4.0 ENVIRONMENTAL IMPACTS / ENVIRONMENTAL CONSEQUENCES

This document has been prepared as a joint EIR/EIS as a result of the combined local, State, and federal actions associated with the approval of the proposed MSHCP. As stated in the Purpose and Need (Section 1.0), the co-lead agencies are the County of Riverside, pursuant to CEQA, and the USFWS, pursuant to NEPA. A consistent format was used to assist the reader in understanding the implications of the proposed MSHCP and alternatives. This section provides a narrative of how the analysis was undertaken and presents the organization of the environmental consequences section of the document.

This section of the EIR/EIS forms the scientific and analytical basis for the evaluation of the proposed MSHCP and alternatives. Topics analyzed include biological resources; land use and planning; population, housing and employment; public services (fire protection and parks); and transportation and circulation. Sections are presented in the following format.

Thresholds of Significance/Criteria for Determining Significance

The criteria for determining significance provide a threshold at which a significant impact will occur. Criteria will differ among issues.

Impact Analysis per Issue Statement

This section of the document provides an evaluation of project-specific and alternatives impacts and determines significance based on documented thresholds levels. The Proposed Project/Action is the MSHCP as described in Section 2.3.1 of this EIR/EIS, to include the whole of the action (policy statements, issuance of incidental take authorizations, and the implementing agreement).

According to NEPA, each of the alternatives to the Proposed Action must be analyzed in equal detail as the Proposed Action. In this Section of the EIR/EIS, each environmental issue described in Section 3.0 of this document is analyzed with regard to potential effects related to the proposed MSHCP (Proposed Action) and to each of the four alternatives as well (Listed, Proposed, and Strong Candidate Species Alternative; Listed and Proposed Species Alternative; Existing Reserves Alternative; and the No Project/No MSHCP Alternative).

The Proposed Action and the alternatives are analyzed for direct, indirect, and cumulative impacts/effects.

Mitigation Measures

For those impacts that were determined to be significant, mitigation is provided in this section of the impact analysis.

Level of Significance after Mitigation

An analysis of the significance of an effect after mitigation is applied is discussed in this section of the impact analysis. The outcome of the analysis is to determine whether there is a significant effect caused by the proposed project or its alternatives that cannot be mitigated to below a level of significance.

for biological resources applies the applicable threshold of significance to the potential effects for the Project and each alternative (with the exception of the No Project Alternative) for each of the following biological issues:

Subheadings for each of these issues appear in the analysis section for the project and alternatives. The No Project Alternative discussion is structured differently, since that alternative does not involve issuance of take authorization. The No Project Alternative discussion is formatted to address existing local, State and federal regulations, and the effects of the application of these regulations to future growth in the MSHCP Area.

Impact Analysis Considerations

Consideration in evaluating impacts to sensitive vegetation communities is based on the vegetation data base developed by Pacific Southwest Biological Services (PSBS, 1995) which is based on 1992-1993 aerial photographs. It is important to distinguish between “vegetation communities” and “habitats.” The terms often are used interchangeably, but a vegetation community precisely refers to definable and consistent assemblages of plant species, whereas habitat is the native environment of a plant or animal species.

The vegetation map as incorporated into the MSHCP database is depicted in Figure

4.1.1. This map was created by PSBS and mapped by KTU+A in 1995. As stated in the February 1995 PSBS/KTU+A Western Riverside County Multi-Species Habitat Conservation Plan Phase I Information Collection and Evaluation Report, this map was created by compiling all known vegetation information within the Plan Area. These data sources include biological survey reports, Weislander vegetation maps, satellite imagery and the Dangermond/RECON data set. Methods used to create and interpret vegetation data included aerial photograph interpretation, edge matching, digitizing, and geographically registering the data. In areas of concern, ground truthing occurred. Vegetation types were classified according to Holland. It should be noted that the vegetation map is representative of conditions at the time of the study; existing conditions today may differ from those represented on the map. The MSHCP vegetation map is limited by the time frame within which the data were assembled as well as the precision of those data. The Project encompasses all of western Riverside County, a

total of 1,966 square miles. Due to the large scale of the Project, it is simply not possible to map the Project area with parcel-level precision. Rather, vegetation mapping was based on a broad scale, as has been done with other criteria-based MSHCPs that cover large geographic regions, such as the San Diego MSCP. The vegetation map represents conditions at the time the data were assembled, in this case 1991-1995; the current extent and character of vegetation communities may differ from that depicted on the MSHCP vegetation map. Published and anecdotal data suggest that ecosystem state transition is occurring within some portions of the Plan Area - in particular, fire suppression has resulted in the conversion of frequently burned chaparral and coastal sage scrub to grassland and in shifts from Ponderosa pine and Jeffrey pine to incense cedar and white fir (Minnich, et al., 1995; Keeley, 1990; Zedler, et al., 1983). The MSHCP incorporates features to update the vegetation map as new information is obtained, such as the development of a new vegetation map as part of the MSHCP Monitoring Program. The timing and methodology for developing this map is described in Section 5.3 of this document. The criteria-based format of the MSHCP was designed, in part, to address changing data and/or conditions. The MSHCP calls for assembly of 153,000 acres of Additional Reserve Lands from within an approximately 300,000-acre Criteria Area. Reserve Assembly will involve review of a variety of project-specific vegetation data to refine and guide the Reserve Assembly process. This criteria-based format differs somewhat from large-scale NCCPs/HCPs for which a specific reserve boundary is delineated on a map at the time of permit issuance. Under that type of approach, validation of the vegetation map at the landscape level may be more important than under the criteria-based approach selected for this MSHCP. The organizational structure established for the MSHCP, as described in Section 6.6 of this document, also provides opportunities to incorporate new information during the term of the MSHCP Permit(s).

Consideration in evaluation of impacts to species is based on the MSHCP Species Occurrence Database. The University of California at Riverside (UCR) has assembled a species occurrence database for use during the MSHCP planning process. This database is accessible via http://ecoregion.ucr.edu/mshcp, and is a clearinghouse for biological information for the MSHCP. Occurrence information has been compiled from museum records, USFWS data, published and unpublished accounts, environmental impact reports, and field notes of local naturalists. As of August 2001, this database contained over 12,800 records. It should be noted that the species occurrence data represent known records of species observations. Actual presence and distribution of individual species within the MSHCP Area are likely greater than those reflected in the species occurrence database. Therefore, the analysis contained in this EIR/EIS also includes consideration of vegetation community associations for covered species. As noted in later sections of this analysis, impacts to non-covered species are not quantifiable due to the lack of information available for these species.

Considerations in evaluating reserve design and biological function of cores and linkages involve the following general principles of conservation biology:

Conservation of focus species and their habitats throughout the MSHCP Area;
Conservation of large habitat blocks;
Maintenance of habitat diversity;
Contiguity and connectivity of Conservation Areas; and
Protection of Conservation Areas from encroachment and invasion by nonnative species.

Specific considerations in evaluating cores and linkages are based on the discussion of the function of cores and linkages contained in Section 3.1 of the MSHCP. The effects of the various alternatives on identified cores and linkages are based on the configuration of the Conservation Areas proposed under each alternative. The evaluation of impacts to cores and linkages is considered in the report prepared by the California Wilderness Coalition in November 2000. The report identified the location and major threats to wildlife movement corridors throughout the State of California (California Wilderness Coalition, 2000). The report identified 232 linkages within the State, of which 17 are located within the MSHCP Area. As part of this analysis, a review of the 17 linkages was conducted to compare reserve features of the MSHCP to the linkages identified by the California Wilderness Coalition.

The evaluation of impacts related to Covered Activities is based on the inventory of Covered Activities contained in Section 7.0 of the MSHCP. As stated below, it is assumed that the same list of covered activities would apply to all of the plan alternatives.

Consideration of regional resource planning is based on the following existing planning efforts. As shown in Figure 4.1.2, resource conservation planning efforts surrounding the MSHCP Area consist of the following:

(1) San Bernardino Preliminary MSHCP Planning Area. This conservation planning effort is adjacent to the northern border of the MSHCP Area and encompasses approximately 500 square miles containing six unique habitat types, six State endangered or threatened species, 13 federally endangered or threatened species, and over 53 species of special concern. San Bernardino County, through its Natural History Museum staff, has been conducting biological and botanical surveys for the past several years in order to identify habitat needs and requirements for the various sensitive species.

(2) Coachella Valley MSHCP Alternative 2. This conservation planning effort covers the central portion of Riverside County (adjacent to the eastern border of the MSHCP Area) which is the westernmost edge of the Sonoran Desert. The plan area covers 1,136,261 acres, a diverse mixture of desert and mountain habitats and 28 species in the Coachella Valley. The Coachella Valley Association of Governments (CVAG) has prepared an Administrative Review Draft which reflects the work of the Scientific Advisory Committee, the Implementation Subcommittee, and the Project Advisory Group. After receiving comments from the local, State, and federal agencies, a Public Review Draft and Draft EIR/EIS is scheduled for release in 2002.

(3) County of San Diego Multiple Habitat Conservation and Open Space Program (MHCOSP). The MHCOSP is adjacent to the southern border of the MSHCP Area and the eastern border of the San Diego MSCP North County Subarea. The County of San Diego has deferred planning for this subregion until it completes its North County Subarea Plan MSCP amendment.

(4) San Diego Multiple Species Conservation Program (MSCP) North County Subarea. In December 1996, the California Department of Fish and Game (CDFG) and the U.S. Fish and Wildlife Service (USFWS) approved the San Diego MSCP habitat plan that encompasses 582,000 acres and establishes a 172,000-acre preserve system in southwestern San Diego County. This subregional plan covers 85 species of plants and animals and 23 vegetation types. The San Diego MSCP contains the North County Subarea, which is adjacent to the southern border of the Riverside County MSHCP Area and the western border of the MHCOSP County of San Diego. Lands formerly within the Multiple Habitat Conservation Program (MHCP) area have been redefined as the North County Subarea of the San Diego MSCP and will be amended into the MSCP. Additional biological information has been collected, and a science advisory process is underway. A subarea plan is anticipated to be provided for review shortly.

(5) Proposed Orange County Southern Subregion NCCP Planning Area. Orange County and major landowners are preparing a subregional preserve plan (NCCP/HCP) and special area management plan/master streambed alteration agreement that will integrate wetlands and endangered species permits. The Southern Subregion conservation planning effort is adjacent to the southern half of the western border of the MSHCP Area. An update to Orange County's General Plan and Zoning Ordinance is also underway. A public workshop was held in December 2001, to discuss alternatives that should be addressed for each of the three planning efforts in southern Orange County. Currently the Southern Subregion NCCP is in the public scoping process for the EIS/EIR that is anticipated to be provided for public review in the next few months.

(6) Orange County Central-Coastal Subregion NCCP Planning Area. This subregion NCCP borders the northern half of the western border of the MSHCP Area. This conservation plan was approved in July 1996 and establishes a 37,380-acre reserve system that includes significant areas of 12 major habitat types and covers 39 sensitive plant and animal species.

(7) Orange County Northern Subregion. This subregion borders a small portion of the northwestern corner of the MSHCP Area. This subregion is not a part of Orange County's NCCP plan, but a Chevron USA 4(d) permit concurrence letter was issued by the Wildlife Agencies that will allow Chevron to complete oil field abandonment operations in this subregion. The permit also commits Chevron to setting aside and managing a 28-acre preserve area for California gnatcatchers and funding cowbird control efforts.

4.1.2 Assumptions

The analysis of impacts to biological resources of the Proposed Action-MSHCP and the Plan alternatives - is also based on the following assumptions:

109) All of the following policies related to avoiding or reducing biological impacts, which are outlined in the MSHCP, would be incorporated into all of the proposed alternatives, with the exception of the No Project Alternative and the Existing Reserves Alternative:

Wetlands avoidance and minimization (MSHCP, Section 6.1.2);
Narrow endemics survey/conservation requirements (MSHCP, Section 6.1.3);
Additional survey requirements (MSHCP, Section 6.3.2); and
Guidelines pertaining to Urban/Wildlands Interface (MSHCP, Section 6.1.4).

110) With the exception of the No Project Alternative, all of the alternatives are assumed to include Adaptive Management and Monitoring for the species that are covered under each of the respective alternatives consistent with the measures described for those species in Section 5.0 of the MSHCP.

111) Implementation strategy (i.e., Criteria-based plan) is assumed to be the same for all of the alternatives, with the exception of the No Project Alternative and the Existing Reserves Alternative. It is assumed that Criteria would be established for these alternatives that would result in conservation in the same manner as the MSHCP Criteria.

112) Covered activities are assumed to be the same under all of the alternatives with the exception of the No Project Alternative and the Existing Reserves Alternative.

113) Through the MSHCP process, there has been a total of 254 species identified for analysis of potential conservation within the MSHCP Area. This includes the 247 species originally identified by the Wildlife Agencies early in the MSHCP development process, plus seven additional species considered in the planning process. It is assumed that the list of 254 species encompasses all species for which adequate information is available to conduct an analysis under CEQA and NEPA. Analysis of species other than the 254 identified that are not known to exist in the MSHCP Area, have not been identified, or have not been taxonomically distinguished, would involve speculation that is not within the scope of this analysis.

114) For the No Project Alternative, there would be no core/linkage system, no coordinated biological management, and no coordinated strategy for assembling contiguous blocks of reserve lands. Any conservation that would be achieved with the No Project Alternative would result from regulatory requirements imposed upon individual projects.

115) Lands defined as “Public/Quasi-Public” includes lands known to be in public ownership managed for conservation and/or open space value, or land contained in an existing reserve. Assembly of the public/quasi-public lands database revealed that approximately 347,000 acres of public/quasi-public lands are present within the MSHCP Plan Area, including approximately 200,000 acres of lands within the Cleveland or San Bernardino National Forests that are owned by the federal government and managed by the U.S. Forest Service. It is assumed that the same level of conservation and management that is described for the MSHCP would also occur under the other alternatives, with the exception of the No Project Alternative, with the only difference being the focus of management directed at the species covered under each of these alternatives.

116) For the purpose of this analysis, cumulative biological impacts are defined as those impacts resulting from development within the MSHCP Area as a result of build out of the County's and Cities' General Plans, in accordance with SCAG regional growth projections. The term of the MSHCP is proposed to be 75 years, and the MSHCP includes consideration of growth and development within the MSHCP Plan Area for build out of the General Plans. This analysis examines all of the alternatives under a General Plan build out scenario.

Therefore, the analysis of cumulative biological impacts of the Proposed Action and alternatives is assumed to be incorporated into the analysis of the alternatives themselves, since cumulative growth including build out of the General Plans in accordance with SCAG regional growth projections is considered in the MSHCP and the alternatives.

4.1.3 Thresholds of Significance/Criteria for Determining Significance

The following criteria are used to determine whether the Project or the alternatives would have significant impacts on biological resources. The impacts would be significant if implementation of the Project or the alternative being analyzed would:

Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species (including species listed as threatened or endangered) in local or regional plans, policies, or regulations, or by the CDFG or USFWS;
Have a substantial adverse effect on any wetlands or other sensitive natural vegetation community identified in local or regional plans, policies, or regulations or by the California Department of Fish and Game or the United States Fish and Wildlife Service;
Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, impede the use of native wildlife nursery sites, or obstruct genetic flow for identified planning species;
Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or State habitat conservation plan, either within the MSHCP Plan Area or in the surrounding region;
Introduce land use within an area immediately adjacent to the MSHCP Conservation Area that would result in substantial edge effects; or
Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance.

4.1.4 Impacts

MSHCP Proposed Project

Vegetation Communities. For the purposes of this analysis, vegetation types have been grouped into four primary categories: sensitive upland, wetland, forest, and agriculture. Sensitive upland communities include chaparral, coastal sage scrub, desert scrub, grassland (native grassland only, non-native grassland is not a sensitive community), and Riversidean alluvial fan sage scrub vegetation types. Wetland communities include meadows and marshes, playas and vernal pools, water and riparian scrub/woodland/forest vegetation types. Forest communities include montane coniferous forest, peninsular juniper woodland and scrub, and woodlands and forests.

For sensitive upland communities within the MSHCP Area, implementation of the proposed MSHCP would authorize take of 37 percent of chaparral, 48 percent of coastal sage scrub, 66 percent of desert scrub, 72 percent of grassland (including both native and non-native grassland), and 34 percent of Riversidean alluvial fan sage scrub (Table 4A).

For wetland communities within the MSHCP Area, the proposed MSHCP would authorize take of 76 percent of meadows and marshes, 15 percent of playas and vernal pools, 15 percent of water, and 26 percent of riparian scrub/woodland/forest. For forest communities within the MSHCP Area, the proposed MSHCP would authorize take of 31 percent of montane coniferous forest, and 32 percent of woodlands and forests. In addition, 88 percent of the agricultural land in the Plan Area would be authorized for take under the proposed MSHCP, as it would be outside the MSHCP Conservation Area and could be used for agricultural activities.

Source: Western Riverside County MSHCP, November 2002.

Certain features incorporated in the MSHCP would minimize to the extent feasible potential impacts to sensitive vegetation communities. These include assembly of an approximately 500,000-acre MSHCP Conservation Area encompassing Conserved Habitat. Conserved Habitat is defined as land that is permanently protected and managed for the benefit of the Covered Species with the Proposed Action under legal arrangements that prevent its conversion to other uses. The acreages of vegetation communities not authorized for take would be included as Conserved Habitat within the MSHCP Conservation Area. For example, while 31 percent of the montane coniferous forest would be in the take authorized area for the Proposed Action, 69 percent of the montane coniferous forest would be included in the MSHCP Conservation Area as Conserved Habitat. In general, inclusion of the majority of the forest communities as Conserved Habitat within the MSHCP Conservation Area would not result in a substantial reduction of these communities, therefore impacts are considered to be less than significant.

For the sensitive upland communities, inclusion of 63 percent of the chaparral within the MSHCP Conservation Area would not result in a substantial reduction of these communities given the large percentage of this vegetation community to be included as Conserved Habitat with the Proposed Action, the extensive acreage and wide distribution of this vegetation community in the Plan Area, and the relatively low numbers of listed species preferring this vegetation community within the Plan Area. For coastal sage scrub and Riversidean alluvial fan sage scrub, although 52 percent and 66 percent of these vegetation communities, respectively, would be included as Conserved Habitat, substantial impacts to coastal sage scrub and Riversidean alluvial fan sage scrub would remain due to the patchy distribution of these vegetation communities in the Plan Area and the relatively large numbers of sensitive species occurring in these vegetation communities. However, features incorporated into the proposed project, including the configuration of conserved lands, as well as adaptive management and monitoring, would reduce this impact to a less than significant level. The Project would reduce grassland (including native and non-native grassland) and desert scrub by 72 percent and 66 percent, respectively. Features incorporated into the proposed Plan, including the configuration of conserved lands, as well as adaptive management and monitoring, would reduce impacts to desert scrub to a less than significant level. However, as the vegetation coverage does not distinguish between native and non-native grassland, impacts to sensitive native grassland cannot be quantified independently, and significant impacts to this vegetation community may still occur.

With respect to agriculture, the Project and its associated take authorization could result in impacts to 88 percent of this vegetation community. However, agriculture is not a sensitive natural vegetation community. Thus, impacts to agriculture are not regarded as biologically significant. (For analysis of whether the Project and the alternatives will have significant impacts on agriculture, see Section 4.2. Impacts to species that utilize agricultural lands are discussed below in Impacts to Listed Covered Species and Impacts to Non-Listed Covered Species.)

Section 6.1.2 of the MSHCP discusses mapping of riparian, riverine, vernal pools, and other potentially jurisdictional wetland areas as part of the CEQA review of applications for Covered Activities within the MSHCP Plan Area. The policy calls for avoidance and minimization of impacts to wetland habitat throughout the Plan Area in accordance with existing regulatory standards that call for conservation and mitigation of wetland functions and values. Together, inclusion of substantial acreages of wetland vegetation communities within the MSHCP Conservation Area, and implementation of the Riparian/Riverine/Vernal Pool policy incorporated in the MSHCP, would reduce identified impacts to wetland vegetation communities to a level below significance. Thus implementation of the MSHCP will not have a substantial adverse impact on any wetland or other sensitive natural community identified in local or regional plans, policies, or regulations or by the Wildlife Agencies.

Listed Covered Species. The proposed MSHCP Conservation Area encompasses approximately 500,000 acres, comprising 347,000 acres of public/quasi-public land and 153,000 acres of Additional Reserve Lands and conserves portions of all vegetation communities distributed throughout the MSHCP Plan Area. Representative vegetation communities from the seven bioregions in the Plan Area are conserved with the Proposed Action. No developed areas or disturbed habitats are proposed for conservation.

The MSHCP provides take authorization for covered species resulting from Covered Activities outside of the Criteria Area, as well as those Covered Activities that are consistent with the Criteria and permitted inside the Criteria Area. In addition, coverage is provided for certain activities within the Criteria Area and within existing public/quasi-public lands, including maintenance and minor improvements to existing roads, improvements related to planned roads, and limited future facilities, such as electrical, gas, water, sewer, flood control, and State Park facilities.

The MSHCP includes specific criteria for locating such facilities and provides guidelines for design of the facilities that would avoid or reduce impacts. The best available information has been used to include a quantitative analysis of the impacts from these facilities, which is included in the impacts associated with the Plan as a whole, as presented in Table 4A. It should be noted, however, that existing and future roadways within the Criteria Area, including General Plan Circulation Element Roads, CETAP facilities, and Caltrans facilities would not be included in the total acreage considered for conservation within the MSHCP Conservation Area.

As a result of issuance of the proposed 10(a) permit, the species identified in Table 4B could be legally taken by permitted jurisdictions where they occur outside of the MSHCP Conservation Area. Nineteen of the 83 covered wildlife species and 13 of the 63 covered plant species are listed under FESA or CESA. These 19 wildlife species and 13 plant species will be directly affected by the Plan because they will no longer receive protection outside of the MSHCP Conservation Area. The impacts to the 32 Listed Covered Species are quantified based on the best existing information available for known occurrences and potential suitable habitat for each Listed Covered Species (Table 4B). These impacts vary depending on the species. For example, as shown in Table 4B, implementation of the proposed take authorization would result in the potential direct loss of 45 percent of suitable habitat for the coastal California gnatcatcher. For vernal pool fairy shrimp, approximately 12 percent of suitable habitat occurring outside of the MSHCP Conservation Area would be directly affected, and no known localities would be affected.

Features have been incorporated in the MSHCP to minimize impacts to Listed Covered Species to the extent feasible. These include assembly of an MSHCP Conservation Area that incorporates substantial acreages of suitable habitat and known locations in a configuration that provides live-in and linkage habitat for a number of species. For example, core populations of coastal California gnatcatcher at Alberhill, North Peak, Kabian Park, and Ramsgate would be conserved, as well as linkages, such as the Sedco Hills and Gavilan Plateau, to other localities in the MSHCP Area. Criteria-based Reserve Assembly would occur in a manner consistent with Rough Step policies and the Habitat Evaluation and Acquisition Negotiation Strategy, and other implementation strategies as described in Section 6.1.1, MSHCP, Volume I.

In addition, the proposed MSHCP includes policies that would afford additional protection to some Listed Covered Species occurring outside of the MSHCP Conservation Area. The narrow endemics plant species policy and the additional survey needs policy, described in Section 6.1.3 and 6.3.2, respectively, of the MSHCP, Volume I, require surveys to be conducted as part of the project review process for public and private projects where suitable habitat is present. The following Listed Covered Species are subject to the narrow endemic plant species and additional survey needs policies.

Narrow Endemic Plant Species Policy

Munz's onion
San Diego ambrosia
San Jacinto Valley crownscale
Nevin's barberry
thread-leaved brodiaea

Vail Lake ceanothus
slender-horned spine flower
spreading navarretia
California Orcutt grass

Additional Survey Needs Policy

western yellow-billed cuckoo
southwestern willow flycatcher

least Bell's vireo
San Bernardino kangaroo rat

Species detected during surveys would be conserved in accordance with the respective applicable policy. Information gathered as a result of species surveys would serve to fill data gaps and inform monitoring and management for a species. The additional survey requirements and information gathering efforts would be implemented until the MSHCP Conservation Area is assembled in a manner that is consistent with the conservation objectives for individual species.

Wetland species occurring outside of the MSHCP Conservation Area may also receive additional protection as a result of implementation of the policy related to riparian, riverine, and vernal pool areas described in Section 6.1.2 of the MSHCP, Volume I. As part of this policy, survey, mapping, and documentation of riparian, riverine, vernal pool systems, and other areas that are identified as jurisdictional under Section 1600 et seq. of the California Fish and Game Code or Sections 401, 402, or 404 of the Federal Clean Water Act would occur. These areas may include playas and vernal pools, open water, meadows and marshes, riparian scrub, woodlands and forests, and other habitat types, known to occur in the Plan Area. For areas containing riparian, riverine, or vernal pool features that are located outside of the MSHCP Conservation Area, avoidance and minimization measures, as required as mitigation through the CEQA process or State/federal regulatory processes, would be employed. The avoidance and minimization measures would reduce impacts to wetland habitats supporting Listed Covered Species. The following Listed Covered Species would benefit from implementation of the wetland policy.

Listed Covered Wetland Species

vernal pool fairy shrimp
Riverside fairy shrimp
Santa Ana sucker
arroyo toad
California red-legged frog
mountain yellow-legged frog
western yellow-billed cuckoo
southwestern willow flycatcher

peregrine falcon
bald eagle
least Bell's vireo
California Orcutt grass
San Jacinto Valley crownscale
thread-leaved brodiaea
San Diego button-celery
spreading navarretia

If suitable habitat were determined to be present, focused surveys for the following Listed Covered Species would be conducted: least Bell's vireo, southwestern willow flycatcher, western yellow-billed cuckoo, vernal pool fairy shrimp, and Riverside fairy shrimp. Localities of wetland species observed during focused surveys would be conserved in accordance with the process of wetland conservation identified in Section 6.1.2 of the MSHCP.

Additional covered activities inside the Criteria Area that are considered to be allowable uses within the MSHCP Conservation Area but have not been included in the quantification of impacts contained in Table 4A are the allowances for development of single-family homes on existing legal parcels within the Criteria Area and the possible allowance of agricultural conversion on lands within the Criteria Area up to a maximum of 10,000 acres.

Development of individual single-family homes on existing legal parcels (hereinafter referred to as the “Single-Family Home Expedite Process”), in accordance with existing land use regulations, is a covered activity within the Criteria Area. An expedited review process, through the Property Owner Initiated Habitat Evaluation and Acquisition Negotiation Process has been developed as part of the MSHCP to assist in determining the appropriate location of a single-family home or mobile home on an existing legal lot within the Criteria Area.

If during the review period it is determined that all or part of the property may benefit the assembly of the MSHCP Conservation Area, the Permittee may negotiate with the property owner to acquire the entire lot or portion thereof or determine which incentives may apply in order to acquire a conservation easement over that portion of the property that is not necessary for access road(s) and outside of the building footprint area. If the Permittee is unable to reach agreement with the property owner concerning the acquisition of the entire lot or a conservation easement over a portion of the lot upon completion of the review period, the property owner may proceed with the processing of the grading or site preparation permit application. However, compliance with the location of the building footprint area as well as the location of any necessary road(s) will be required.

Trend data collected from 1995 to mid 2002 suggests that, on average, there is development of approximately 75 single-family homes on lots averaging approximately 9 acres in size within the Criteria Area on an annual basis. Therefore, the Single-Family Home Expedite Process will have the potential to affect approximately 675 acres of land within the Criteria Area annually. For the purpose of this analysis, it is assumed that approximately 50 percent of that area, or 338 acres, potentially within the area subject to take authorization by such development will be within areas of sensitive habitat that are considered desirable for inclusion in the Reserve. This is based on the overall ratio of Additional Reserve Lands to Criteria Area, which is roughly one half. Based on the trend data and average parcel size, that 338 acres represents approximately 38 parcels. It is estimated that the Permittees will be able to successfully negotiate with 75 percent, or 29 of the 38 property owners through the Property Owner Initiated Habitat Evaluation and Acquisition Negotiation Process. Therefore, it is assumed that conservation that conforms to the Criteria will be achieved on approximately 253 of the 338 acres of land per year that is potentially within the area subject to take authorization through this process. It is assumed that the remaining approximately 85 acres will not be developed in accordance with the Criteria and will become unavailable for conservation on an annual basis, as a result of the Single-Family Home Expedite Process.

The inability to incorporate into the Reserve approximately 85 acres of land that is desirable for conservation throughout the Plan Area on an annual basis will not reduce the overall acreage required for Additional Reserve Lands. So while conservation may be precluded on an estimated average of 85 acres per year, it is not expected that this will adversely affect the ability to assemble a viable MSHCP Conservation Area, since there is adequate additional land within the Criteria Area that could be acquired in lieu of the areas subject to development under the Single-Family Home Expedite Process.

In addition, annual reporting will determine whether the activity of single-family home development occurs in a manner that is consistent with the assumptions used for the MSHCP analysis. The number of grading or site preparation permits for the construction or location of a single-family home or a mobile home on an existing legal lot located within the Criteria Area will be monitored and reported on at least an annual basis in order to insure that appropriate assembly of the MSHCP Conservation Area is occurring. Therefore, no significant impacts on Covered Species will result from the construction or location or single-family or mobile homes on existing legal lots within the Criteria Area.

If Section 6.3 of the MSHCP is implemented, conversion of natural lands to agricultural use, as defined and outlined in that section of the MSHCP, will be allowed as a covered activity within the Criteria Area, up to an established threshold of 10,000 acres over the life of the plan ( the “New Agricultural Lands Cap”). Agricultural Operations, as defined in Section 6.3 of the MSHCP, include all uses conducted as a normal part of such operations, provided such actions are in compliance with all applicable laws and regulations.

To verify the location of the existing Agricultural Operations, the County will establish a database identifying existing Agricultural Operations (“Existing Agricultural Operations Database”) on or before the effective date of the Implementing Agreement or the issuance of the Section 10(a) Permit and the NCCP Authorization. The new Agricultural Lands Cap of 10,000 acres within the Criteria Area will be applied to Agricultural Operations that are in addition to the activities recorded in the Existing Agricultural Operations Database. The 10,000-acre New Agricultural Lands Cap represents approximately 3 percent of the total acreage that is contained within the Criteria Area.

To estimate the potential effects of New Agricultural Lands in relation to the MSHCP, it is assumed that approximately 50 percent of the agricultural conversions that take place within the Criteria Area will be consistent with the Criteria. Therefore, it is assumed that approximately 5,000 acres of New Agricultural Lands will occur within areas considered desirable for conservation under the Criteria. This represents approximately 1.5 percent of the total Additional Reserve Lands proposed to be acquired within the Criteria Area. Tracking of MSHCP implementation, and adjustments to Reserve Assembly strategies as outlined in this section, will provide a mechanism to ensure that adequate acreage of Additional Reserve Lands is being acquired, and that appropriate reserve design and configuration are being achieved. Therefore, no significant biological impacts to Listed Covered Species are anticipated to result from New Agricultural Lands Cap.

With the combination of impact reduction features incorporated into the Proposed Project, including reserve configuration, adaptive management and monitoring, and species survey and avoidance/minimization policies, the Project's impacts to Listed Covered Species would be less than significant.

Non-Listed Covered Species. The Non-Listed Covered Species include 65 of the 83 covered wildlife species and 52 of 63 plant species. The impacts to the 115 Non-Listed Covered Species are quantified based on the best existing information available for known occurrences and potential suitable habitat for each Non-Listed Covered Species (Table 4C). These impacts vary depending on the species. For example, as shown on Table 4C, implementation of the proposed take authorization would result in take authorization for 75 percent of suitable habitat for the burrowing owl. For Santa Rosa Plateau pool fairy shrimp, approximately 15 percent of suitable habitat occurring outside of the MSHCP Conservation Area would be within the area subject to take authorization. For certain Non-Listed Covered Species, such as arroyo chub and San Bernardino flying

Features have been incorporated in the MSHCP to minimize impacts to Non-Listed Covered Species. These include assembly of an MSHCP Conservation Area that incorporates substantial acreages of suitable habitat and known locations in a configuration that provides live-in and linkage habitat for a number of species. For example, core populations of Bell's sage sparrow at Lake Skinner/Diamond Valley Lake, Aguanga, and the Jurupa Mountains, would be conserved, as well as linkages, such as the Sedco Hills and Hogbacks, to other localities in the MSHCP Plan Area. The Criteria-based Reserve Assembly would occur in a manner consistent with Rough Step policies and the Habitat Evaluation and Acquisition Negotiation Process described in Section 6.1.1, MSHCP, Volume I.

The direct and indirect impacts of Covered Activities on Non-Listed Covered Species would be the same as for Listed Covered Species.

In addition, the proposed MSHCP includes policies that would afford some additional protection to Non-Listed Covered Species occurring outside of the MSHCP Conserva-tion Area. The narrow endemics plant species policy and the additional survey needs policy, described in Section 6.1.3 and 6.3.2, respectively, of the MSHCP, Volume I, require surveys to be conducted as part of the project review process for public and private projects where suitable habitat is present. The following Non-Listed Covered Species are subject to the narrow endemic plant species policy and additional survey needs policy.

Narrow Endemic Plant Species Policy

Yucaipa onion
Johnston's rock-cress
Munz's mariposa lily
many-stemmed dudleya
San Jacinto Mountains bedstraw

Brand's phacelia
San Miguel savory
Hammitt's clay-cress
Wright's trichocoronis

Additional Survey Needs Policy

burrowing owl
Aguanga kangaroo rat
Los Angeles pocket mouse
smooth tarplant

Coulter's goldfields
little mousetail
Parish's brittlescale
Nevin's barberry

Species detected during surveys would be conserved in accordance with the respective applicable policy. Information gathered as a result of species surveys would serve to fill data gaps and inform monitoring and management for a species. The additional survey requirements and information-gathering efforts would be implemented until the MSHCP Conservation Area is assembled in a manner that is consistent with the conservation objectives for individual species.

Wetland species occurring outside of the MSHCP Conservation Area may also receive additional protection as a result of implementation of the policy related to riparian, riverine, and vernal pool areas, described in Section 6.1.2 of the MSHCP, Volume I. As part of this policy, survey, mapping, and documentation of riparian, riverine, vernal pool systems, and other areas that are identified as jurisdictional under Section 1600 et seq. of the California Fish and Game Code or Sections 401, 402, or 404 of the federal Clean Water Act would occur. These areas may include playas and vernal pools, open water, meadows and marshes, riparian scrub, woodlands and forests and other habitat types, known to occur in the Plan Area. For areas containing riparian, riverine, and vernal pool features that are located outside of the MSHCP Conservation Area, wetlands avoidance and minimization measures, required as mitigation through the CEQA process or State/Federal regulatory processes, would be employed. The avoidance and minimization measures would reduce impacts to wetland habitats supporting a number of Non-Listed Covered Species, including 10 plant species and 22 wildlife species. The following Non-Listed Covered Species would benefit from implementation of this policy.

Non-Listed Covered Wetland Species

coast range newt
western spadefoot
western pond turtle
American bittern
Lincoln's sparrow breeding
Macgillivray's warbler
Nashville warbler

California spine flower
Coulter's goldfields
Davidson's saltscale
little mousetail
Orcutt's brodiaea
Parish's brittlescale
Parish's meadowfoam
vernal barley
Wright's trichocoronis

If suitable habitat were determined to be present, focused surveys for the Santa Rosa Plateau fairy shrimp would be conducted. Localities of wetland species observed during focused surveys would be conserved in accordance with wetland conservation policies described in Section 6.1.2 of the MSHCP.

With the combination of impact-reduction features incorporated into the proposed project, including reserve configuration adaptive management and monitoring, and species survey and avoidance/minimization policies, impacts to Non-Listed Covered Species would be less than significant.

Non-Covered Species. The list of species that receive coverage under the MSHCP is in part the result of previous analyses conducted by USFWS in their preparation of Tables 1 and 2 included in an August 9, 1999 Draft Proposal for the MSHCP (DUDEK & Associates, 1999). Table 1 of the August 9, 1999 Draft Proposal formed the basis for the initial species list to be considered for conservation in the MSHCP and Table 2 represented the list of species for which additional information was still needed to fully consider the species for conservation.

Together, Tables 1 and 2 identified 247 species for consideration in the MSHCP, and 8 additional species were added to the list under consideration. Through the MSHCP process, a total of 255 species were identified as having the potential to exist within the MSHCP area. Upon the completion of additional analyses and literature reviews by DUDEK and the Wildlife Agencies with respect to species accounts, the final list of Covered Species was narrowed to 146 species. The list of 255 species encompasses all species for which adequate information is available to conduct an impact analysis under CEQA and NEPA. Analysis of species other than the 255 identified would involve speculation that is not required by CEQA or NEPA.

Of these 255 species, it has been determined that the MSHCP will not include 109 of these species as Covered Species. Table 4D includes a list of these 109 species, including an explanation of why the species were not included as Covered Species under the MSHCP. While it is assumed that the conservation provided under the MSHCP could potentially benefit Non-Covered Species that occur within the MSHCP Conservation Area, it is not possible to quantify the level of conservation because of the lack of information available for these species or because the species are not known to occur within the MSHCP Area. The features of the MSHCP that would contribute to the conservation of non-covered species would include maintenance of cores and linkages and impact avoidance and minimization policies. In addition, mitigation of adverse effects offered through the Adaptive Management and Monitoring Programs would provide overall benefits to habitats that could result in a certain level of conservation for non-covered species. However, even with these benefits offered by the Proposed Plan, because of the lack of information available to plan adequately for conservation of these species, impacts, including impacts resulting from Covered Activities, are assumed to be potentially significant and not mitigable.

Cores and Linkages. As described in the Proposed Plan, the MSHCP Conservation Area comprises a variety of existing and proposed cores, extensions of existing cores, linkages, constrained linkages, and non-contiguous habitat blocks. These features, generally referenced as cores and linkages, are depicted in Figure 4.1.3. The following is a summary of definitions that apply to the legend items shown in Figure 4.1.3.

Core	A block of habitat of appropriate size, configuration, and vegetation characteristics to generally support the life history requirements of one or more Covered Species. Although a more typicaldefinition is population-related and refers to a single species(Hunter, 2002; Primack, 2000), in the MSHCP this term is habitat-related because of the multi-species nature of the Proposed Plan.
Extension of Existing Core	A block of habitat contiguous with an existing core area, which serves to provide additional habitat for species in the adjacent existing core and to reduce exposed edge.
Non-contiguous Habitat Block	A block of habitat not connected to other habitat areas via a linkage or constrained linkage.
Constrained Linkage	A constricted connection expected to provide for movement of identified Planning Species between core areas, where options for assembly of the connection are limited due to existing patterns of use.
Linkage	A connection between core areas with adequate size, configuration and vegetation characteristics to generally provide for “live-in” habitat and/or provide for genetic flow for identified Planning Species. Areas identified as linkages in the Proposed MSHCP may provide movement habitat but not live-in habitat for some species, thereby functioning more as movement corridors. Since it is expected that every linkage will provide live-in habitat for at least one species, and since the term “corridor” may be easily confused with the term as it is applied to transportation corridors discussed in the CETAP portion of the RCIP, the term linkage is used here. For a more thorough discussion of linkage and movement corridors, see Section 3.1.4 of the MSHCP Project, Applicable Conservation Biology Principles.

As shown in Table 4E, all of the cores and linkages depicted in Figure 4.1.3 would be incorporated in the MSHCP Conservation Area under the Proposed MSHCP. As noted in the discussion of the Relationship to Adopted or Approved HCPs and NCCPs, these cores and linkages include all the missing links identified in the California Wilderness Coalition Report for cores and linkages in the South Coast Ecoregion. Certain links (like the link from Palomar Mountains to Santa Ana Mountains) include locations not within the MSHCP Area or involve lands that are not a part of the MSHCP. For example, the Palomar Mountains to Santa Ana Mountains linkage includes lands in San Diego County and American Indian Lands that are not a part of the MSHCP. MSHCP is contributing cores and linkages within additional Reserve Lands. Chapter 3 of the Draft MSHCP identifies the distance between existing cores.

The proposed Plan provides for the movement of native resident and migratory species and protects established wildlife corridors and genetic flow. The Plan also protects the use of native wildlife nursery sites. Therefore, impacts related to cores and linkages resulting from the Plan are considered to be less than significant.

Relationship to Adopted or Approved HCPs or NCCPs. As shown in Figure 4.1.2, Regional MSHCP Context, the Additional Reserve Lands and existing public/quasipublic lands do not conflict with the provisions of any adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or State habitat conservation plan, either within the MSHCP Plan Area or in the surrounding region. Rather, the MSHCP will complement other regional planning efforts, including those that are currently underway but have not yet been approved.

The discussion below describes the public and private lands that will provide connection to regional conservation planning adjacent to the MSHCP Area in the different alternative scenarios, and the extent to which the MSHCP will incorporate the missing linkages in the South Coast Ecoregion described in the California Wilderness Coalition Report.

San Bernardino Preliminary MSHCP Planning Area. The northern border of the Plan Area will continue to provide conservation planning in the Santa Ana River and the San Bernardino National Forest (Existing Cores A and I, respectively). In addition to those existing cores, Proposed Linkages 6, 5, and 4, and Proposed Noncontiguous Habitat Blocks 1, 2, and 3 are proposed in the northern border of the Plan Area. These existing and proposed cores and linkages provide connection to the San Bernardino Preliminary MSHCP Planning Area to the North.

Coachella Valley MSHCP Alternative 2. In the eastern border of the MSHCP Area, connection to the Coachella Valley MSHCP Alternative 2 is provided through San Bernardino National Forest and Anza-Borrego Desert State Park (Existing cores K and L, respectively).

San Diego MSCP North County Subarea and MHCOSP. Beauty Mountain Management Area (BLM land), Agua Tibia Mountain Wilderness Area, Santa Margarita Ecological Reserve, and the Cleveland National Forest will continue to be managed for biological resources and will provide connection to the MHCOSP and San Diego MSCP North County Subarea to the south of the MSHCP Area (Existing Cores L, M, G, and B, respectively). A parcel of BLM-owned land (Existing Linkage A), may be used to move from Pechanga Creek south into San Diego County, and Proposed Core 7 will also provide connection south into the MHCOSP through a mosaic of upland and wetland habitat. Proposed Constrained Linkages 9, 10, 11, and 12 connect the Santa Rosa Plateau and Tenaja Corridor to San Diego MSCP North County Subarea to the south, and Proposed Linkage 9 will also provide connection to the Cleveland National Forest in San Diego County.

Orange County Proposed Southern, and Central and Coastal Subregion NCCP Planning Area. The MSHCP provides connection into the Southern and Central and Coastal Subregion NCCP Planning Areas to the west through the Cleveland National Forest (Existing Core B). However, in the southwestern corner of the MSHCP Area is a small piece of land designated as “rural mountainous” surrounded by Cleveland National Forest to the north and east, with the proposed Orange County Southern Subregion NCCP Planning Area to the west. This small piece of land is not proposed to be part of the MSHCP Additional Reserve Lands and does not provide connection to surrounding regional conservation planning. As the Orange County Southern Subregion NCCP is developed, the location of this land should be taken in to account by all affected planning agencies.

Missing Linkages in the California Wilderness Coalition Report. The Proposed MSHCP has incorporated the missing linkages identified in the California Wilderness Coalition Report.

Edge Effects. An edge effect is defined as a change in the “conditions or species composition within an otherwise uniform habitat as one approaches a boundary with a different habitat” (Ricklefs, 1993). Edge effects at the boundary between natural lands and human-occupied lands (“urban edge effects”) arise due to human-related intrusions such as lighting, noise, invasive species, exotic predators (e.g., dogs, cats, and opossums), hunting, trapping, off-road activities, dumping, and other forms of recreation and disturbance. Although some species are in some ways unaffected by edges -- for example, reproductive output of the rufous-crowned sparrow (Morrison and Bolger, 2002), distribution of arthropod species (Bolger, et al., 2000) - or even show preferences for edges - for example, indigo buntings and northern cardinals in Woodward, et al. (2001) - human-induced edge effects are generally unfavorable to native species.

Edge effects could occur to species and habitats within the MSHCP Conservation Area if proposed land uses and activities in take authorized areas occur in proximity to the MSHCP Conservation Area. Edge effects may be short-term effects related to construction or long-term effects associated with development or land use practices in proximity to Conserved Habitat areas. For the Proposed Action, it is assumed that edge effects resulting from construction activities include dust, noise, and general human It is assumed that edge effects resulting from development or land use practices in proximity to Conserved Habitat areas include long-term presence of unshielded noise-generating land uses in proximity to the MSHCP Conservation Area; unshielded night-lighting directed within the MSHCP Conservation Area; use of exotic landscape plant materials that may invade native vegetation communities within the MSHCP Conservation Area; discharge of uncontrolled or unfiltered urban runoff toward the MSHCP Conservation Area, including potential toxics; and uncontrolled access, dumping or trespass within the MSHCP Conservation Area.

For those cores and linkages with higher perimeter-to-area ratios, as identified in Table 4E, edge effects would be considered to have a greater effect on Conserved Habitat and Covered Species than for the larger cores and linkages incorporated in the MSHCP Conservation Area.

As noted in the discussions of Impacts to cores and linkages and Impacts Related to Covered Activities, a variety of features have been incorporated into the proposed MSHCP that will minimize edge effects. These include the following:

Implementation of standard BMPs (Appendix C of the MSHCP);
Implementation of the Land Use Guidelines Pertaining to the Urban/Wildlands Interface (Section 6.1.4 of the MSHCP); and
Implementation of the siting, design, construction, operations, and maintenance guidelines for Covered Activities within the Criteria Area and Allowable Uses within the MSHCP Conservation Area (Section 7.0 of the MSHCP).

With these features incorporated, the MSHCP's edge effects are less than significant.

Listed, Proposed, and Strong Candidate Species Alternative

Vegetation Communities. For sensitive upland communities within the MSHCP Area, implementation of this alternative would authorize take of 43 percent of the chaparral, 53 percent of the coastal sage scrub, 90 percent of the desert scrub, 75 percent of the grassland (including native and non-native grassland), and 44 percent of the Riversidean alluvial fan sage scrub (Table 4F). For wetland communities within the MSHCP Area, this alternative would authorize take of 81 percent of the meadows and marshes, 26 percent of the playas and vernal pools, 17 percent of water, and 38 percent of the riparian scrub, woodland and forest. For forest communities within the MSHCP Area, this alternative would authorize take of 31 percent of the montane coniferous forest, and 35 percent of the woodlands and forests. In addition, 84 percent of the agricultural land in the Plan Area would be authorized for take by implementation of this alternative.

Notes: 1 Impacts associated with the No Project Alternative are presented separately. 2 Includes cismontane alkali marsh. 3 Totals exclude developed/disturbed land, because no additional impact to biological resources would occur in these areas as a result of implementation of the Proposed MSHCP or alternatives. Source: Western Riverside County MSHCP, November 2002.

Certain features incorporated in the MSHCP would minimize impacts to sensitive vegetation communities. These include assembly of an approximately 477,000-acre MSHCP Conservation Area encompassing Conserved Habitat. Conserved Habitat is defined as land that is permanently protected and managed for the benefit of the Covered Species under this alternative under legal arrangements that prevent its conversion to other uses. The acreages of vegetation communities not authorized for take under this alternative would be included as Conserved Habitat within the MSHCP Conservation Area. For the sensitive upland communities, inclusion of 57 percent of the chaparral within the MSHCP Conservation Area under this alternative would reduce identified impacts to these communities to a level below significance given the large percentage of this vegetation community to be included as Conserved Habitat under this alternative, the extensive acreage and wide distribution of this vegetation community in the Plan Area, and the relatively low numbers of listed species preferring this vegetation community within the Plan Area. For Riversidean alluvial fan sage scrub, although 56 percent of this vegetation community would be included as Conserved Habitat under this alternative, significant impacts to Riversidean alluvial fan sage scrub would remain due to the patchy distribution of this vegetation community in the Plan Area and the relatively large numbers of sensitive species occurring in this vegetation community. Due to the large percentages of coastal sage scrub (53%), grassland (75%) (including native and non-native grassland), and desert scrub (90%) potentially within the area subject to take authorization within the take authorized area under this alternative, significant impacts to these vegetation communities would occur even with application of the minimization measures. With respect to agriculture, although the proposed take authorization under this alternative would apply to 84 percent of this vegetation community, this vegetation community is not a sensitive natural community, so impacts to agriculture are not considered biologically significant. (As noted previously, impacts to agriculture are analyzed in Section 4.2, and impacts to species that utilize agricultural lands have been analyzed in the discussions of impacts to Listed Covered Species and impacts to Non-Listed Covered Species.)

In addition, Section 6.1.2 of the MSHCP discusses mapping of riparian, riverine, vernal pools, and other potentially jurisdictional wetland areas as part of review of applications for Covered Activities within the MSHCP Area. The policy calls for avoidance and minimization of impacts to wetland habitat throughout the Plan Area in accordance with existing regulatory standards that call for no net loss of wetland functions and values. Together, inclusion of substantial acreages of wetland vegetation communities within the MSHCP Conservation Area under this alternative, and implementation of the policy related to riparian, riverine, and vernal pool areas incorporated in the MSHCP, would reduce identified impacts to wetland vegetation communities to a level below significance.

Listed Covered Species. The Listed, Proposed, and Strong Candidate Species Alternative encompasses approximately 466,000 acres, comprising 347,000 acres of public/quasipublic land and 119,000 acres of Additional Reserve Lands, and conserves portions of all vegetation communities distributed throughout the MSHCP Area. Representative vegetation communities from the seven bioregions in the Plan Area are conserved under this scenario. None of the land cover types identified on the vegetation map as developed or disturbed are proposed for conservation.

As a result of issuance of a 10(a) permit, the listed species identified in Table 4B could be legally taken by permitted jurisdictions where they occur outside of the MSHCP Conservation Area. The list of Listed Covered Species for this alternative is the same as for the MSHCP Project. The Listed Covered Species would be directly affected by the take authorization because they will no longer receive protection outside of the MSHCP Conservation Area. The impacts to the 32 Listed Covered Species are quantified based on the best existing information available for known occurrences and potential suitable habitat for each Listed Covered Species (Table 4B).

Covered activities under this alternative would be identical to those described for the MSHCP. Therefore, the impacts to Listed Covered Species associated with Covered Activities, including development of single-family homes or location of mobile homes on existing legal parcels and conversion of natural lands to agricultural use (as defined However, the impacts of this alternative would be generally much greater in magnitude when compared to the proposed MSHCP. For example, loss of suitable habitat for southwestern willow flycatcher would be 4,735 acres (34%) under this alternative, and the loss of suitable habitat under the proposed MSHCP would be approximately 3,220 acres (23%) (Table 4B). For certain Listed Covered Species, such as Delhi Sands flower-loving fly and Munz's onion, the precise quantity of the impact is undetermined at this time due to lack of existing available information regarding these species.

Features are incorporated into the Listed, Proposed, and Strong Candidate Species Alternative to minimize impacts to Listed Covered Species. These include assembly of an MSHCP Conservation Area that incorporates substantial acreages of suitable habitat and known locations in a configuration that provides live-in and linkage habitat for a number of species. For example, core populations of coastal California gnatcatcher at Alberhill, North Peak, Kabian Park, and Ramsgate would be conserved, as well as linkages, such as the Sedco Hills and Gavilan Plateau, to other localities in the MSHCP Area. Criteria-based Reserve Assembly would occur in a manner consistent with Rough Step policies and the Habitat Evaluation and Acquisition Negotiation Process described in Section 6.1.1, MSHCP, Volume I.

In addition, this alternative includes policies that would afford some Listed Covered Species occurring outside of the MSHCP Conservation Area additional protection. The narrow endemics plant species policy and the additional survey needs policy, described in Section 6.1.3 and 6.3.2, respectively, of the MSHCP, Volume I, require surveys to be conducted as part of the project review process for public and private projects where suitable habitat is present. The following Listed Covered Species are subject to the narrow endemic plant species and additional survey needs policies.

Narrow Endemic Plant Species Policy

Munz's onion
San Diego ambrosia
San Jacinto Valley crownscale
Nevin's barberry
thread-leaved brodiaea

Vail Lake ceanothus
slender-horned spine flower
spreading navarretia
California Orcutt grass

Additional Survey Needs Policy

western yellow-billed cuckoo
southwestern willow flycatcher

least Bell's vireo
San Bernardino kangaroo rat

Species detected during surveys would be conserved in accordance with the respective applicable policy. Information gathered as a result of species surveys would serve to fill data gaps and inform monitoring and management for a species. The additional survey requirements and information gathering efforts would be implemented until the MSHCP Conservation Area is assembled in a manner that provides for long-term conservation of these species.

Wetland species occurring outside of the MSHCP Conservation Area may also receive additional protection as a result of implementation of the policy related to riparian, riverine, and vernal pool areas, described in Section 6.1.2 of the MSHCP, Volume I. As part of the wetland policy, survey, mapping and documentation of riparian, riverine, vernal pool systems, and other areas that are identified as jurisdictional under Section 1600 et seq. of the California Fish and Game Code or Sections 401, 402, or 404 of the Federal Clean Water Act would occur. These areas may include playas and vernal pools, open water, meadows and marshes, riparian scrub, woodlands and forests, and other habitat types, known to occur in the Plan Area. For mapped resources that are located outside of the MSHCP Conservation Area, wetlands avoidance and minimization measures, consistent with existing regulations, would be employed. The avoidance and minimization measures would reduce impacts to wetland habitats supporting Listed Covered Species. The following Listed Covered Species would benefit from implementation of the policy related to riparian, riverine, and vernal pool areas.

Listed Covered Wetland Species

vernal pool fairy shrimp
Riverside fairy shrimp
Santa Ana sucker
arroyo toad
California red-legged frog
mountain yellow-legged frog
western yellow-billed cuckoo
southwestern willow flycatcher

peregrine falcon
bald eagle
least Bell's vireo
California Orcutt grass
San Jacinto Valley crownscale
thread-leaved brodiaea
San Diego button-celery
spreading navarretia

If suitable habitat were determined to be present, focused surveys for the following Listed Covered Species would be conducted: least Bell's vireo, southwestern willow flycatcher, western yellow-billed cuckoo, vernal pool fairy shrimp, and Riverside fairy shrimp. Localities of wetland species observed during focused surveys would be conserved in accordance with wetland conservation policies contained in Section 6.1.2 of the MSHCP.

A reduced level of conservation of suitable habitat and species localities at Temescal Wash, Vail Lake, Temecula Creek, Wilson Creek, Anza Valley, Badlands, and Reche Canyon is anticipated under this alternative. Areas such as the Jurupa Mountain, Cactus Valley, and a number of linkages, including Warm Springs Creek, Tenaja Corridor, Tule Creek, Cahuilla Creek, Garden Aire Wash, and Noble Creek, previously identified for inclusion as part of the MSHCP Conservation Area, would be excluded under this alternative. However, with application of the narrow endemic policy, additional survey needs policy and wetlands policy, as well as reserve assembly and configuration, direct and indirect impacts to Listed Covered Species would be reduced to less than significant levels.

Non-listed Covered Species. Implementation of the Listed, Proposed, and Strong Candidate Species Alternative would result in direct and indirect impacts to Non-Listed Covered Species. The Non-Listed Covered Species for the Listed, Proposed and Strong Candidate Species Alternative include those species identified in Table 4G.

The species identified in Table 4G could be legally taken by permitted jurisdictions where they occur outside of the MSHCP Conservation Area. The impacts to the Non-Listed Covered Species are quantified based on the best existing information available for known occurrences and potential suitable habitat for each Non-Listed Covered Species (the analysis summary for these species is contained in Table 4C).

Covered activities under this alternative would be identical to those described for the MSHCP. Therefore, the impacts to Non-Listed Covered Species associated with Covered Activities, including development of single-family homes or location of mobile homes on existing legal parcels and conversion of natural lands to agricultural use (as defined and outlined in Section 6.3 of the MSHCP, if implemented) within the Criteria Area, are the same as they are for the MSHCP.

The impacts of this alternative would be generally much greater in magnitude when compared to the proposed MSHCP. For example, loss of suitable habitat for yellow-breasted chat would be 4,085 acres (33%) under this alternative, and the loss of suitable habitat under the proposed MSHCP would be approximately 2,780 acres (22%) (Table 4C). For certain Non-Listed Covered Species, such as arroyo chub and San Bernardino flying squirrel, the precise quantification of the impact is undetermined at this time due to lack of existing available information regarding these species.

Features are incorporated into the Listed, Proposed, and Strong Candidate Species Alternative to minimize impacts to Non-Listed Covered Species. These include assembly of an MSHCP Conservation Area that incorporates substantial acreages of suitable habitat and known locations in a configuration that provides live-in and linkage habitat for a number of species. For example, core populations of Bell's sage sparrow at Lake Skinner/Diamond Valley Lake, Aguanga, and the Jurupa Mountains, would be conserved, as well as linkages, such as the Sedco Hills and Hogbacks, to other localities in the Plan Area. Criteria-based Reserve Assembly would occur in a manner consistent with Rough Step policies and the Habitat Evaluation and Acquisition Negotiation Process described in Section 6.1.1, MSHCP, Volume I.

In addition, this alternative includes policies that would afford some Non-Listed Covered Species occurring outside of the MSHCP Conservation Area additional protection. The narrow endemics plant species policy and the additional survey needs policy, described in Section 6.1.3 and 6.3.2, respectively, of the MSHCP, Volume I, require surveys to be conducted as part of the project review process for public and private projects where suitable habitat is present. The following Non-Listed Covered Species are subject to the narrow endemic plant species and additional survey needs policies.

Species detected during surveys would be conserved in accordance with the respective applicable policy. Information gathered as a result of species surveys would serve to fill data gaps and inform monitoring and management for a species. The additional survey requirements and information gathering efforts would be implemented until the MSHCP Conservation Area is assembled in a manner that provides for long-term conservation of these species.

Wetland species occurring outside of the MSHCP Conservation Area may also receive additional protection as a result of implementation of the policy related to riparian, riverine, and vernal pool areas, described in Section 6.1.2 of the MSHCP, Volume I. As part of this policy, survey, mapping and documentation of riparian, riverine, vernal pool systems, and other areas that are identified as jurisdictional under Section 1600 et seq. of the California Fish and Game Code and Sections 401, 402, and 404 of the Federal Clean Water Act would occur. These areas may include playas and vernal pools, open water, meadows and marshes, riparian scrub, woodlands and forests, and other habitat types, known to occur in the Plan Area. For mapped habitat located outside of the MSHCP Conservation Area, avoidance and minimization measures, consistent with existing regulations, would be employed. The avoidance and minimization measures would reduce impacts to wetland habitats supporting a number of Non-Listed Covered Species. The following Non-Listed Covered Species would benefit from implementation of this policy.

A reduced level of conservation of suitable habitat and species localities at Temescal Wash, Vail Lake, Temecula Creek, Wilson Creek, Anza Valley, Badlands, and Reche Canyon is anticipated under this alternative. Areas such as the Jurupa Mountain, Cactus Valley, and a number of linkages, including Warm Springs Creek, Tenaja Corridor, Tule Creek, Cahuilla Creek, Garden Aire Wash, and Noble Creek, previously identified for inclusion as part of the MSHCP Conservation Area, would be excluded under this alternative. However, adequate conservation for the Non-Listed Covered Species is provided with this alternative. It should be noted that certain species that are covered under the MSHCP Project are not covered under this alternative.

Non-Covered Species. The list of defined Non-Covered Species for the Listed, Proposed, and Strong Candidate Species Alternative is presented in Table 4H. Any conservation benefits that would accrue to these species as a result of the MSHCP project would be reduced under this alternative, due to the reduction in overall Conservation Area. However, as noted, it is not possible to fully quantify the potential adverse effects to Non-Covered Species at this time due to the lack of information for these species. Please also refer to discussion of impacts to non-covered species for the proposed MSHCP. Impacts to non-covered species, including impacts resulting from Covered Activities, are therefore assumed to be potentially significant and not mitigable.

Cores and Linkages. Under the Listed, Proposed, and Strong Candidate Species Alternative, all of the cores and linkages noted in Table 4E for this alternative would be incorporated into the MSHCP Conservation Area. As noted in the discussion of the Relationship to Adopted or Approved HCPs and NCCPS, these cores and linkages include most but not all of the missing links identified by the California Wilderness Coalition in its study of linkage priorities in the South Coast Ecoregion, for which the MSHCP has the ability to incorporate such cores and linkages. Table 4E also identifies the proposed cores and linkages that are not included as part of this alternative. Most notable is the exclusion of the constrained linkages from French Valley to Diamond Valley Lake/Lake Skinner (Proposed Constrained Linkages 17 and 18), the proposed linkages and core areas from Diamond Valley Lake/Lake Skinner to the San Jacinto Mountains and Wilson Valley (Proposed Linkage 13 and 14 and Proposed Cores 4 and 7) and the linkages from the Santa Rosa Plateau to Orange County (Proposed Linkage 9) and San Diego County (Proposed Constrained Linkages 9, 10, 11, and 12). Also reduced conservation would occur in the Badlands, Reche Canyon, Wilson Valley, Vail Lake, and Temecula Creek areas under this alternative.

Absence of these cores and linkages would have significant effects with respect to certain species, as well as overall function of the MSHCP Conservation Area. For example, the absence of the linkages from French Valley to the Diamond Valley Lake/Lake Skinner Reserve would affect movement by common mammals and avian species in this area and isolate populations of species occurring within the Diamond Valley Lake/Lake Skinner Reserve. The exclusion of Cactus Valley (Proposed Core 4) from the MSHCP Conservation Area would adversely affect the function of the MSHCP Conservation Area by not providing a connection from Diamond Valley Lake/Lake Skinner to National Forest Lands to the east. Absence of this linkage would isolate the existing multi-species reserve from existing conserved lands to the east. Take authorized in this area would adversely affect planning species identified for this Proposed Core, including Quino checkerspot butterfly. These effects are regarded as significant.

Assembly of the cores and linkages will occur in accordance with the reserve assembly process outlined in the MSHCP Plan, Volume I. However, the combination of constrained linkages and a less robust reserve design under this alternative may affect the ability of the cores and linkages to function. This is regarded as a significant effect.

Relationship to Adopted or Approved HCPs and NCCPs. The following discussion focuses on regional planning efforts. Significant impacts are anticipated due to the failure to maintain critical linkage components present in other adopted HCPs and NCCPs.

San Bernardino Preliminary MSHCP Planning Area. Connections to the San Bernardino Preliminary MSHCP Area to the north are generally the same as discussed for Proposed MSHCP with the exception that Proposed Noncontinuous Habitat Block 2 has been reduced in size, and Proposed Linkage 4 has been eliminated. Proposed Linkage 4 served to create missing linkage 36 in the California Wilderness Coalition Report. Elimination of this connection north into the San Bernardino Mountains could cause conflicts with regional conservation planning efforts, although the San Bernardino MSHCP is not yet adopted or approved.

Coachella Valley MSHCP Alternative 2. Impacts to connections to the Coachella Valley MSHCP area to the east are essentially the same as discussed for the Proposed MSHCP.

San Diego MSCP North County Subarea and MHCOSP. Impacts to connection to resource planning areas in San Diego County to the south are generally the same as discussed for the Proposed MSHCP; however, Proposed Linkage 9 is eliminated under this alternative. Proposed Linkage 9 serves as one of the missing linkages identified as a high priority linkage in the California Wilderness Coalition Report (linkage 55) providing connection to the southeast corner of Cleveland National Forest. Elimination of this linkage could cause conflicts with regional habitat conservation plans and is considered to be a significant impact.

Orange County Proposed Southern, and Central and Coastal Subregion NCCP Planning Area. Connections to the Orange County NCCP Planning Areas to the west are the same as discussed for the Proposed Project. Regional conservation planning impacts discussed under the Proposed MSHCP also apply to this alternative.

Missing Linkages in the California Wilderness Coalition Report. This alternative eliminates Proposed Extension of Existing Core 2. This core extension serves as missing linkage 45 identified in the California Wilderness Coalition Report connecting the Santa Ana Mountains to Lake Matthews. This alternative also eliminates Proposed Constrained Linkages 15 and 18. Proposed Constrained Linkages 15 and 18 serve as missing linkage 58 connecting Diamond Valley Lake to west of Temecula. Elimination of these missing linkages could cause conflicts to regional conservation planning and is considered to be a significant impact. In addition, elimination of the missing linkages discussed under connections north and south into San Bernardino and San Diego Counties, respectively, are also considered to be significant impacts under this alternative.

The same features incorporated in the MSHCP to minimize edge effects would be incorporated in this alternative, including the standard BMPs; Land Use Guidelines Pertaining to the Urban/Wildlands Interface; and siting, design, construction, operations, and maintenance guidelines for Covered Activities and Allowable Uses. However, significant edge effects would remain even with implementation of these minimization measures because of the reduction in cores and linkages under this alternative when compared with the proposed MSHCP.

Listed and Proposed Species Alternative

Vegetation Communities. For sensitive upland communities within the MSHCP Area, implementation of this alternative would authorize take of 46 percent of the chaparral, 59 percent of the coastal sage scrub, 91 percent of the desert scrub, 78 percent of the grassland (including native and non-native grassland), and 44 percent of the Riversidean alluvial fan sage scrub (Table 4I). For wetland communities within the MSHCP Area, this alternative would authorize take of 82 percent of the meadows and marshes, 11 percent of the playas and vernal pools, 18 percent of water, and 40 percent of the riparian scrub, woodland and forest. For forest communities within the MSHCP Area, this alternative would authorize take of 31 percent of the montane coniferous forest, and 35 percent of woodlands and forests. In addition, 84 percent of the agricultural land in the Plan Area would be within the area subject to take authorization by implementation of this alternative.

Certain features incorporated in the MSHCP would minimize impacts to sensitive vegetation communities. These include assembly of an approximately 440,800-acre MSHCP Conservation Area encompassing Conserved Habitat. Conserved Habitat is defined as land that is permanently protected and managed for the benefit of the Covered Species under this alternative under legal arrangements that prevent its conversion to other uses. Under this alternative, to the extent the vegetation communities are not authorized for take, they would be included as Conserved Habitat within the MSHCP Conservation Area. For example, 31 percent of the montane coniferous forest would be in the take authorized area under this alternative, and 69 percent of the montane coniferous forest would be included in the MSHCP Conservation Area as Conserved Habitat. In general, inclusion of the majority of the forest communities as Conserved Habitat within the MSHCP Conservation Area under this alternative would reduce identified impacts to these communities to a level below significance.

For the sensitive upland communities, inclusion of 54 percent of the chaparral within the MSHCP Conservation Area under this alternative would reduce identified impacts to these communities to a level below significance given the large percentage of this vegetation community to be included as Conserved Habitat, the extensive acreage and wide distribution of this vegetation community in the Plan Area, and the relatively low numbers of listed species preferring this vegetation community within the Plan Area. For Riversidean alluvial fan sage scrub, although 56 percent of this vegetation community would be included as Conserved Habitat under this alternative, significant impacts to Riversidean alluvial fan sage scrub would remain due to the patchy distribution of this vegetation community in the Plan Area and the relatively large numbers of sensitive species occurring in this vegetation community. Due to the large percentages of coastal sage scrub (59%), grassland (78%) (including native and nonnative grassland), and desert scrub (91%) potentially within the area subject to take authorization within the take authorized area, significant impacts to these vegetation communities would occur even with application of the minimization measures. With respect to agriculture, although the proposed take authorization under this alternative would apply to 84 percent of this vegetation community, this vegetation community is not a sensitive natural community, so impacts to agriculture are not considered biologically significant. (As noted previously, impacts to agriculture are analyzed in Section 4.2, and impacts to species that utilize agricultural lands have been analyzed in the discussions of impacts to Listed Covered Species and impacts to Non-Listed Covered Species.)

Notes: 1 Impacts associated with the No Project Alternative are presented separately. 2 Includes cismontane alkali marsh. 3 Totals exclude developed/disturbed land, because no additional impact to biological resources would occur in these areas as a result of implementation of the Proposed MSHCP or alternatives. Source: MSHCP.

Section 6.1.2 of the MSHCP contains policies related to riparian, riverine, and vernal pool areas that call for mapping of riparian, riverine, vernal pools, and other potentially jurisdictional wetland areas as part of review of applications for Covered Activities within the MSHCP Area. The policy calls for avoidance and minimization of impacts to these areas throughout the Plan Area in accordance with existing regulatory standards. Together, inclusion of substantial acreages of wetland vegetation communities within the MSHCP Conservation Area under this alternative, and implementation of the riparian, riverine, and vernal pool policy incorporated in the MSHCP, would reduce identified impacts to wetland vegetation communities to a level below significance.

Listed Covered Species. The Listed and Proposed Species Alternative encompasses approximately 440,800 acres, comprising 440,800 acres of public/quasi-public land and 93,800 acres of Additional Reserve Lands, and conserves portions of all vegetation communities distributed throughout the MSHCP Area. Representative vegetation communities from the seven bioregions in the Plan Area are conserved under this scenario. No developed or disturbed habitats are proposed for conservation.

As a result of issuance of a 10(a) permit, the species identified in Table 4B could be legally taken by permitted jurisdictions where they occur outside of the MSHCP Conservation Area. The list of Listed Covered Species for this alternative is the same as for the proposed MSHCP. Likewise, the Covered Activities permitted under this alternative would be identical to those described for the MSHCP. Therefore, the impacts associated with Covered Activities would be the same as for the MSHCP.

The Listed Covered Species would be directly impacted by the alternative because they will no longer receive protection outside of the MSHCP Conservation Area. The impacts to the 32 Listed Covered Species are quantified based on the best existing information available for known occurrences and potential suitable habitat for each Listed Covered Species (Table 4B). The impacts of this alternative would be generally much greater in magnitude when compared to the proposed MSHCP. For example, loss of suitable habitat for southwestern willow flycatcher would be 4,990 acres (36%) under this alternative, while the loss of suitable habitat under the proposed MSHCP would be approximately 3,220 acres (23%). For certain Listed Covered Species, such as Munz's onion, the precise quantity of the impact is undetermined at this time due to lack of existing available information regarding these species.

Features are incorporated into the Listed and Proposed Species Alternative to minimize impacts to Listed Covered Species. These include assembly of a Conservation Area that incorporates substantial acreages of suitable habitat and known locations in a configuration that provides live-in and linkage habitat for a number of species. For example, core populations of coastal California gnatcatcher at Alberhill, North Peak, Kabian Park, and Ramsgate would be conserved, as well as linkages, such as the Sedco Hills and Gavilan Plateau, to other localities in the MSHCP Area. Criteria-based Reserve Assembly would occur in a manner consistent with Reserve Assembly process described in Section 6.1.1, MSHCP, Volume I.

In addition, this alternative includes policies that would afford some additional protection to Listed Covered Species occurring outside of the MSHCP Conservation Area. The narrow endemics plant species policy and the additional survey needs policy, described in Sections 6.1.3 and 6.3.2, respectively, of the MSHCP, Volume I, require surveys to be conducted as part of the project review process for public and private projects where suitable habitat is present. The following Listed Covered Species are subject to the narrow endemic plant species and additional survey needs policies.

Species detected during surveys would be conserved in accordance with the respective applicable policy. Information gathered as a result of species surveys would serve to fill data gaps and inform monitoring and management for a species. The additional survey requirements and information-gathering efforts would be implemented until the MSHCP Conservation Area is assembled in a manner that provides for long-term conservation of these species.

Wetland species occurring outside of the MSHCP Conservation Area may also receive additional protection as a result of implementation of the policy related to riparian, riverine, and vernal pool areas, described in Section 6.1.2 of the MSHCP, Volume I. As part of the this policy, survey, mapping, and documentation of riparian, riverine, vernal pool systems, and other areas that are identified as jurisdictional under Section 1600 et seq. of the California Fish and Game Code or Sections 401, 402, or 404 of the Federal Clean Water Act would occur. These areas may include playas and vernal pools, open water, meadows and marshes, riparian scrub, woodlands and forests, and other habitat types, known to occur in the Plan Area. For mapped habitat located outside of the MSHCP Conservation Area, avoidance and minimization measures, consistent with existing regulations, would be employed. The avoidance and minimization measures would reduce impacts to wetland habitats supporting a number of Listed Covered Species. The following Listed Covered Species would benefit from implementation of the policy related to riparian, riverine, and vernal pool areas.

Listed Covered Wetland Species

vernal pool fairy shrimp
Riverside fairy shrimp
Santa Ana sucker
arroyo toad
California red-legged frog
mountain yellow-legged frog
western yellow-billed cuckoo
bald eagle

least Bell's vireo
California Orcutt grass
San Jacinto Valley crownscale
thread-leaved brodiaea
San Diego button-celery

If suitable habitat were determined to be present, focused surveys for the following Listed Covered Species would be conducted: least Bell's vireo, southwestern willow flycatcher, western yellow-billed cuckoo, vernal pool fairy shrimp and Riverside fairy shrimp. Localities of wetland species observed during focused surveys would be conserved in accordance with policies contained in Section 6.1.2 of the MSHCP.

A reduced level of conservation of suitable habitat and species localities at Temescal Wash, Vail Lake, Temecula Creek, Wilson Creek, and Anza Valley is anticipated under this alternative when compared to the proposed MSHCP. Areas such as the Jurupa Mountain, Cactus Valley, Badlands, Reche Canyon, Lakeview Mountains, and a number of linkages, including Warm Springs Creek, Tenaja Corridor, Tule Creek, Cahuilla Creek, Garden Aire Wash, and Noble Creek, previously identified for inclusion as part of the MSHCP Conservation Area, would be excluded under this alternative. Nevertheless, with application of the narrow endemic policy, additional survey needs policy, and riparian, riverine, and vernal pool policy, as well as Reserve Assembly and configuration, impacts to Listed Covered Species would be less than significant.

Non-Listed Covered Species. Implementation of the Listed and Proposed Species Alternative would result in direct and indirect impacts to Non-Listed Covered Species outside the MSHCP Conservation Area. The list of Non-Listed Covered Species for this alternative is included in Table 4J. The analysis summary for these species is contained in Table 4C.

The impacts to the Non-Listed Covered Species are quantified based on the best existing information available for known occurrences and potential suitable habitat for each Non-Listed Covered Species (Table 4C). The impacts of this alternative would be generally much greater in magnitude when compared to the proposed MSHCP. For example, loss of suitable habitat for yellow-breasted chat would be 4,310 acres (35%) under this alternative, and the loss of suitable habitat under the proposed MSHCP would be approximately 2,780 acres (22%) (Table 4C). For certain Non-Listed Covered Species, such as arroyo chub and San Bernardino flying squirrel, the precise quantity of the impact is undetermined at this time due to lack of existing available information regarding these species.

Features are incorporated into the Listed and Proposed Species Alternative to minimize impacts to Non-Listed Covered Species. These include assembly of a Conservation Area that incorporates substantial acreages of suitable habitat and known locations in a configuration that provides live-in and linkage habitat for a number of species. For example, core populations of Bell's sage sparrow at Lake Skinner/Diamond Valley Lake, Aguanga, and the Jurupa Mountains, would be conserved, as well as linkages, such as the Sedco Hills and Hogbacks, to other localities in the MSHCP Area. Criteria-based Reserve Assembly would occur in a manner consistent with Rough Step policies and the Habitat Evaluation and Acquisition Negotiation Process described in Section 6.1.1, MSHCP, Volume I.

In addition, this alternative includes policies that would afford some additional protection to Listed Covered Species occurring outside of the MSHCP Conservation Area . The narrow endemics plant species policy and the additional survey needs policy, described in Section 6.1.3 and 6.3.2, respectively, of the MSHCP, Volume I, require surveys to be conducted as part of the project review process for public and private projects where suitable habitat is present. The following Non-Listed Covered Species are subject to the narrow endemic plant species and additional survey needs policies.

Narrow Endemic Plant Species Policy

Johnston's rock-cress
Munz's mariposa lily
many-stemmed dudleya

San Jacinto Mountains bedstraw
San Miguel savory
Wright's trichocoronis

Additional Survey Needs Policy

smooth tarplant

Species detected during surveys would be conserved in accordance with the respective applicable policy. Information gathered as a result of species surveys would serve to fill data gaps and inform monitoring and management for a species. The additional survey requirements and information-gathering efforts would be implemented until the MSHCP Conservation Area is assembled in a manner that provides for long-term conservation of these species.

Wetland species occurring outside of the MSHCP Conservation Area may also receive additional protection as a result of implementation of the policy related to riparian, riverine, and vernal pool areas, described in Section 6.1.2 of the MSHCP, Volume I. As part of that policy, survey, mapping and documentation of riparian, riverine, vernal pool systems, and other areas that are identified as jurisdictional under Section 1600 et seq. of the California Fish and Game Code or Sections 401, 402, or 404 of the Federal Clean Water Act would occur. These areas may include playas and vernal pools, open water, meadows and marshes, riparian scrub, woodlands and forests, and other habitat types, known to occur in the Plan Area. For mapped habitat located outside of the MSHCP Conservation Area, avoidance and minimization measures, consistent with existing regulations, would be employed. The avoidance and minimization measures would reduce impacts to areas supporting a number of Non-Listed Covered Species. The following Non-Listed Covered Species would benefit from implementation of the riparian, riverine, and vernal pool policy.

A reduced level of conservation of suitable habitat and species localities at Temescal Wash, Vail Lake, Temecula Creek, Wilson Creek, and Anza Valley is anticipated under this alternative when compared to the proposed MSHCP. Areas such as the Jurupa Mountain, Cactus Valley, Badlands, Reche Canyon, Lakeview Mountains, and a number of linkages, including Warm Springs Creek, Tenaja Corridor, Tule Creek, Cahuilla Creek, Garden Aire Wash, and Noble Creek, previously identified for inclusion as part of the MSHCP Conservation Area would be excluded under this alternative. Nevertheless, with application of the narrow endemic policy, additional survey needs policy and riparian, riverine, and wetlands policy, as well as Reserve Assembly and configuration, impacts to Non-Listed Covered Species would be reduced to less than significant levels.

Non-Covered Species. The list of defined Non-Covered Species for the Listed and Proposed Species Alternative is included in Table 4K. Any conservation benefits that would accrue to these species as a result of the MSHCP developed under the Listed and Proposed Species alternative would likely be reduced, due to the reduction in overall Conservation Area. However, as noted, it is not possible to fully quantify the potential adverse effects to Non-Covered Species at this time due to the lack of information for these species. Therefore, impacts to Non-Covered Species, including impacts resulting from Covered Activities, under this alternative are deemed to be significant and unavoidable. Please also refer to discussion of impacts to non-covered species for the proposed MSHCP.

Cores and Linkages. Under the Listed and Proposed Species Alternative, all of the cores and linkages noted in Table 4E and depicted in Figure 4.1.3 would be incorporated into the MSHCP Conservation Area. As noted in the discussion of the Relationship to adopted or approved HCPs and NCCPs, these cores and linkages include some of the missing links identified by the California Wilderness Coalition in their study of linkage priorities in the South Coast Ecoregion, for which the MSHCP has the ability to incorporate such cores and linkages. Table 4E identifies the proposed cores and linkages that are not included as part of this alternative. In addition to the proposed cores and linkages identified as not a part of the Conservation Area under the Listed, Proposed, and Strong Candidate Species Alternative, this alternative also omits proposed core and linkage areas in the Lakeview Mountains, Badlands, Reche Canyon, Tule Creek, and Temecula Creek east of Vail Lake. Also, reduced conservation would occur at Wilson Valley, Vail Lake, and Anza Valley areas under this alternative.

Absence of these cores and linkages would have significant effects with respect to certain species, as well as overall function of the MSHCP Conservation Area. In addition to the significant effects associated with implementation of the Listed, Proposed, and Strong Candidate Species Alternative, significant effects resulting from the exclusion of the Badlands, Reche Canyon, Lakeview Mountains, Tule Creek, and Temecula Creek would occur. For example, under this alternative, the reserve design in the Badlands would be less robust due to the reduced number of acres conserved when compared to the proposed MSHCP. This alternative would not provide large habitat blocks in the Badlands for foraging raptors or mammals connecting to the National Forest lands. The absence of Temecula and Tule Creeks as linkages further isolates core areas in Anza Valley and the Agua Tibia Wilderness.

Assembly of the cores and linkages will occur in accordance with the MSHCP Criteria and the Habitat Evaluation and Acquisition Negotiation Process. However, as noted in Section 3 of the MSHCP, Volume I and in Table 4E of this document, a number of the identified linkages are regarded as constrained linkages and would be within the area subject to take authorization. The combination of constrained linkages and a less robust reserve design under this alternative may affect the ability of the cores and linkages to function. This is regarded as a significant effect.

San Bernardino Preliminary MSHCP Planning Area. Connections to the San Bernardino Preliminary MSHCP Planning Area to the north are generally the same as discussed for the Listed, Proposed, and Strong Candidate Alternative with the exception that Proposed Linkages 5 and 6 have been reduced in size. Impacts discussed for the Listed, Proposed, and Strong Candidate Species Alternative also apply to the Listed and Proposed Species Alternative.

Coachella Valley MSHCP Alternative 2. Connections to the Coachella Valley MSHCP Area to the east are essentially the same as discussed for the Listed, Proposed, and Strong Candidate Alternative.

San Diego MSCP North County Subarea and MHCOSP. Connections to resource planning areas in San Diego County to the south are the same as discussed for the Listed, Proposed and Strong Candidate Species Alternative. Significant impacts discussed under the Listed, Proposed, and Strong Candidate Species Alternative also apply to this alternative.

Orange County Proposed Southern, and Central and Coastal Subregion NCCP Planning Area. Connections to the Orange County NCCP Planning Areas to the west are the same as discussed for the Proposed Project. Regional resource planning impacts discussed under the Listed, Proposed, and Strong Candidate Species Alternative also apply to this alternative.

Missing Linkages in the California Wilderness Coalition Report. Regional planning impacts are the same as those discussed under the Listed, Proposed, and Strong Candidate Species Alternative.

Edge Effects. The types of edge effects under this alternative would be the same as for the proposed MSHCP, and identified impacts would be minimized by the same features incorporated in the MSHCP. As noted in the discussion of Impacts to cores and linkages under this alternative (and identified in Table 4E), all of the proposed cores and linkages and extensions of existing cores and linkages would be absent from this alternative. For these absent cores and linkages under this alternative, no edge effects would occur. Given the greatly increased take authorized area, and the fact that existing cores would remain isolated and would not be connected by new proposed cores and linkages, it is anticipated that significant edge effects would occur for all of the existing cores and linkages under this alternative with the exception of the existing Cleveland and San Bernardino National Forest cores. Edge effects to Conserved Habitats and Covered Species within these cores and linkages would be greater than would occur under the proposed MSHCP. Under this alternative, edge effects to sensitive species not included on the Covered Species list for this alternative, but present within the Conserved Habitat areas, would also occur. The same features incorporated in the MSHCP under the proposed MSHCP to minimize edge effects would be incorporated in this alternative, including the standard BMPs; the Land Use Guidelines Pertaining to Urban/Wildlands Interface; and siting, design, construction, operations, and maintenance guidelines for Covered Activities and Allowable Uses. Significant edge effects would remain even with implementation of these minimization measures for all of the existing cores and

Existing Reserves Alternative

Vegetation Communities. For sensitive upland communities within the MSHCP Plan Area, implementation of this alternative would provide take authorization within areas that include 52 percent of the chaparral, 78 percent of the coastal sage scrub, 91 percent of the desert scrub, 85 percent of the grassland (including native and non-native grassland), and 74 percent of the Riversidean alluvial fan sage scrub (Table 4L). For wetland communities within the MSHCP Plan Area, this alternative would provide take authorization within areas that include 86 percent of the meadows and marshes, 63 percent of the playas and vernal pools, 25 percent of water, and 52 percent of the riparian scrub, woodland and forest. For forest communities within the MSHCP Plan Area, this alternative would provide take authorization in areas that include 31 percent of the montane coniferous forest and 38 percent of the woodlands and forests. In addition, 93 percent of the agricultural land in the Plan Area would be within areas subject to take authorization in this alternative.

Notes: 1 Impacts associated with the No Project Alternative are presented separately. 2 Includes cismontane alkali marsh. 3 Totals exclude developed/disturbed land, because no additional impact to biological resources would occur in these areas as a result of implementation of the Proposed MSHCP or alternatives. Source: Western Riverside County MSHCP, November 2002.

Under the Existing Reserves Alternative, approximately 347,000 acres of existing reserves would be managed to provide Conserved Habitat for as many species as possible. Conserved Habitat is defined as land that is permanently protected and managed for the benefit of the Covered Species under legal arrangements that prevent its conversion to other uses. Under this alternative, the vegetation communities not included in existing reserves would be subject to take authorization. For the sensitive upland communities, due to the large percentages of chaparral (52%), coastal sage scrub (78%), desert scrub (91%), grassland (85%) (including native and non-native grassland), and Riversidean alluvial fan sage scrub (74%) potentially within the area subject to take authorization under this alternative, significant impacts to these vegetation communities would occur even with application of the minimization measures. With respect to agriculture, although 93 percent of this vegetation community is within the area subject to take authorization, this vegetation community is not a sensitive natural community, so impacts to it are not regarded to be significant. (As noted previously, impacts to Agriculture are analyzed in Section 4.2, and impacts to species that utilize agricultural lands are analyzed below in the discussions of impacts to Listed Covered Species and impacts to Non-Listed Covered Species.)

Listed Covered Species. The Existing Reserves Alternative encompasses approximately 347,000 acres comprising public/quasi-public land and land under pre-existing conservation agreements. Land that is shown as developed or disturbed on the vegetation map is not proposed for conservation.

This alternative would not include coverage for the Covered Activities described for the MSHCP except for those Covered Species Adequately Conserved in the existing reserves. Therefore, the Existing Reserves Alternative would not result in any impacts to Listed Covered Species from Covered Activities.

As a result of issuance of a 10(a) permit, the species identified in Table 4M could be legally taken by permitted jurisdictions where they occur outside of the Conservation Area. The Listed Covered Species would be directly affected by the take authorization because they will no longer receive protection outside of Existing Reserves. The impacts to the Listed Covered Species are quantified based on the best existing information available for known occurrences and potential suitable habitat for each Listed Covered Species (Table 4B). The impacts of this alternative would be generally much greater in magnitude when compared to the proposed MSHCP. For example, loss of suitable habitat for southwestern willow flycatcher would be 6,610 acres (48%) under this alternative, while the loss of suitable habitat under the proposed MSHCP would be approximately 3,220 acres (23%) (Table 4B).

Amphibians
California red-legged frog	mountain yellow-legged frog
Birds
peregrine falcon	western yellow-billed cuckoo
Mammals

Because conservation would only occur on Existing Reserves, take authorization would be granted in areas of suitable habitat and known species localities at French Valley, Temescal Wash, Vail Lake, Temecula Creek, Wilson Creek, Anza Valley, the Jurupa Mountain, Cactus Valley, Badlands, Reche Canyon, Lakeview Mountains, and a number of linkages, including San Jacinto River, Bautista Creek, Hemet vernal pools, Sedco Hills, Gavilan Plateau, Warm Springs Creek, Tenaja Corridor, Tule Creek, Cahuilla Creek, Garden Aire Wash, and Noble Creek. Also, under this alternative, an interconnected reserve system that incorporates both live-in and linkage habitat would not be assembled. Therefore, impacts to Listed Covered Species would be significant.

Non-listed Covered Species. The impacts to the Non-Listed Covered Species identified in Table 4N are quantified based on the best existing information available for known occurrences and potential suitable habitat for each Non-Listed Covered Species (Table 4C). The impacts of this alternative would be generally much greater in magnitude when compared to the proposed MSHCP.

This alternative would not include coverage for the Covered Activities described for the MSHCP. Therefore, the Existing Reserves Alternative would not result in any impacts to Non-Listed Covered Species from Covered Activities.

Under this alternative, significant impacts to the Non-Listed Covered Species would occur due to the fact that no additional lands would be conserved as habitat for these species.

Non-Covered Species. The list of defined Non-Covered Species for the Existing Reserves Alternative is contained in Table 4O. Any conservation benefits that would accrue to these species as a result of the MSHCP would be reduced under the Existing Reserves Alternative, due to the reduction in overall Conservation Area. However, as noted, it is not possible to fully quantify the potential adverse effects to Non-Covered Species at this time due to the lack of information for these species. Please also refer to discussion of impacts to non-covered species for the proposed MSHCP. Impacts to Non-Covered Species are therefore assumed to be potentially significant and not mitigable.

Cores and Linkages. As shown in Table 4E, all proposed cores and linkages would be missing from this alternative. This would isolate existing reserves that would continue to be managed for biological resources. Section 3 of the MSHCP identifies the distances between these existing core habitat areas. In addition to isolating cores, the Existing Reserves Alternative would result in increased edge effects. Absence of the proposed cores and linkages would have significant effects with respect to certain species that occur within those cores and linkages, as well as overall function of the MSHCP Conservation Area. For example, the Proposed Core 3 missing from this alternative would adversely affect function of the MSHCP Conservation Area by not connecting the San Bernardino National Forest to the northeast with San Bernardino County and other conserved areas to the north of the core. Absence of this core would authorize take in this core area and would isolate the existing reserve in the San Bernardino National Forest and the Potrero Area of Critical Environmental Concern from the San Bernardino Preliminary MSHCP Planning Area to the north.

Relationship to adopted or approved HCPs and NCCPs. The following section discusses the regional resource planning efforts. Significant impacts are anticipated due to the failure to maintain critical linkage components present in other adopted HCPs and NCCPs.

San Bernardino Preliminary MSHCP Planning Area. Connections to the San Bernardino Preliminary MSHCP Planning Area to the north have changed from those described in the Listed and Proposed Species Alternative. Proposed Noncontiguous Habitat Block 1 and Proposed Linkages 5 and 6 have been eliminated. Proposed Linkages 5 and 6 help create missing linkage 38 from the California Wilderness Coalition report. Eliminating this high priority linkage north to the San Bernardino Mountains could create conflicts to regional conservation planning, and, but as the plan has not yet been adopted, it is not considered to be a significant impact.

Coachella Valley MSHCP Alternative 2. Connections to the Coachella Valley MSHCP planning area to the east are generally the same as those for the Listed and Proposed Alternative. Connections will be maintained through existing public lands.

San Diego MSCP North County Subarea and MHCOSP. This alternative eliminates Proposed Core 7 and its connection south to conservation planning areas in San Diego County, but connection south is still maintained through a variety of public lands as described under the Proposed MSHCP. Significant impacts discussed in the Listed and Proposed Alternative also apply to this alternative.

Orange County Proposed Southern, and Central and Coastal Subregion NCCP Planning Area. Connection west to conservation planning areas in Orange County is the same as that discussed under the Listed and Proposed Species Alternative. Significant impacts discussed in the Listed and Proposed Species Alternative also apply to this alternative.

Missing Linkages in the California Wilderness Coalition Report. Several missing linkages from the California Wilderness Coalition Report have been removed under this alternative in addition to those already discussed under the Listed and Proposed Alternative. These missing linkages include numbers 44 (Corona to Temecula Foothills Linkage), 41 (Mystic Lake/San Jacinto Wildlife Area to Portrero/San Jacinto Mountains Area), 57 (South Lake Skinner to San Jacinto Mountains), 12 (Santa Margarita Ecological Reserve to Cleveland National Forest), 53 (San Jacinto River), 46 (Gavilan Hills to Santa Ana Mountains), 52 (Estelle Mountain/Good Hope to San Jacinto River), and 59 (East Side Reservoir to San Jacinto Foothills). Under the Existing Reserves Alternative, all proposed cores and linkages have been eliminated, so the MSHCP fails to incorporate several missing linkages identified in the South Coast Ecoregion. Failure to provide these linkages could conflict with regional habitat conservation planning and is considered a significant impact.

Edge Effects. The cores and linkages identified for the proposed MSHCP would be absent from this alternative. Edge effects would be exacerbated because of the greatly increased amount of take authorized area, the loss of cores and linkages, and increased human interaction with wildlife. Edge effects would therefore be significant.

No Project Alternative

This section provides an analysis of potential biological impacts associated with the No Project Alternative, which represents the anticipated conditions and circumstances that would result if an MSHCP were not implemented in western Riverside County.

The purpose of this analysis is to roughly quantify and analyze the effects upon habitats and species if no action were to be taken on the MSHCP. The outcome of no action would be continuation of existing regulatory processes related to the development of, and the resulting impacts to, species and habitats. It should be noted that the ability to quantify such impacts to species is limited by the extent of existing data available on the occurrence and distribution of species within the MSHCP Area. Therefore, the rough quantification of impacts is based on estimated impacts to vegetation communities. An additional complication in the quantification of impacts is the inability to accurately predict the extent and pattern of future development and mitigation associated with that development. For the purpose of this analysis, certain assumptions are made regarding the number of acres and type of development that would occur in the future, based on the proposed County of Riverside General Plan and existing city general plan land use designations and policies and SCAG regional growth projections. For example, within the areas within the Rural designation, it is assumed that impacts would occur on approximately 60 percent of the land. This is based on the roughly average minimum parcel size for a single-family dwelling of 10 acres, and the assumption that the loss of habitat value associated with a single-family dwelling is 6 acres. Assumptions for each land use category are noted below.

The section also describes existing regulatory processes that would result in conservation of regulated resources, such as listed species and wetlands. While these mechanisms are described in detail, the mitigation resulting from these processes cannot be accurately quantified. However, it is assumed that the mitigation would occur within areas that would not otherwise be developed (e.g., within areas designated as open space). Therefore, the estimates of conservation resulting from General Plan land use designations and policies also account for individual project mitigation.

Table 4P provides a rough estimate of anticipated impacts to vegetation types based on generalized land uses from the proposed County General Plan update and existing city general plans within the MSHCP Area. These estimates are provided to assist in the analysis of potential impacts and conservation that may result from land use designations, policies, and regulations that are contained in the updated County General Plan and existing city general plans. The County General Plan update contains a land use map that consists of four broad Foundation Component land uses. Land uses depicted in the city general plans have been standardized to these Foundation Components for consistency in this analysis.

Note: 1 Acreages presented in the land use and vegetation summaries are rounded to the nearest 10 acres.

The generalized Foundation Component land use categories are described below. The relative impact/conservation value of these land use components is also estimated. The actual impact or conservation that occurs within these land use categories may differ from the rough estimates provided.

Open Space. Open Space identifies those areas appropriate for the preservation of open space for habitat, recreation, scenic value, mineral resource extraction, and natural resource preservation. This category also identifies remote, large-parceled areas that allow limited development. Areas designated Open Space are assumed to have a very high potential for conservation for the benefit of species addressed in the MSHCP, recognizing that permitted uses and management issues remain to be evaluated. For the purpose of this analysis, it is assumed that 80 percent of natural vegetation communities within the Open Space designated areas would be conserved. This is based on the assumption that approximately 20 percent of open space lands would involve improvements that would preclude conservation.

Rural. Rural identifies those areas with a distinctive rural character, including existing rural communities, and mountainous and desert areas that allow limited development. Areas designated as Rural have some potential for conservation of biological resources. However, the pattern of allowable development may result in fragmentation of habitats that may reduce the value of undeveloped areas for certain suites of species. For the purpose of this analysis, it is assumed that 40 percent of natural vegetation communities would be conserved within the Rural designated areas. This is based on the assumption that approximately 60 percent of rural areas would be developed or disturbed.

Agriculture. Agriculture identifies those areas to be used for agricultural production. Areas designated agriculture have potential for conservation for the benefit of species addressed in the MSHCP; however, disturbance represented by agricultural activities would reduce conservation values. For the purpose of this analysis, it is assumed that 50 percent of land designated Agriculture would result in conservation of species within the MSHCP Area. This is based on the assumption that approximately one-half of agricultural lands would be subject to activities that would preclude conservation.

Community Development. Community Development identifies those areas that are appropriate for urban or suburban development, including areas for single family and multiple family residential uses, commercial, industrial, business park, public facilities, and a mix of uses. Areas with these designations are assumed to have little or no potential for conservation for the benefit of species addressed in the MSHCP. It is assumed that areas within the Community Development designations would result in impacts to 95 percent of natural habitats. This is based on the assumption that approximately 5 percent of Community Development areas would be placed in open space that would have some benefit to species conservation.

The No Project Alternative includes approximately 439,470 acres of land designated as Open Space. Based on the above-stated assumptions, it is anticipated that impacts to 20 percent of natural vegetation communities would occur within this land use category, and that conservation would include including approximately 202,176 acres of chaparral, 24 acres of cismontane alkali marsh, 43,728 acres of coastal sage scrub, 2,000 acres of desert scrub, 23,680 acres of grassland (including native and non-native grassland), 536 acres of meadows, 19,112 acres of montane coniferous forest, 3,792 acres of playas and vernal pools, 6,896 acres of riparian scrub, 1,92 acres of Riversidean sage scrub, 6,344 acres of open water, and 18,072 acres of woodlands.

Within the Rural designation area, impacts to natural vegetation communities would include the following: 75,738 acres of chaparral, 48 acres of cismontane alkali marsh, 33,084 acres of coastal sage scrub, 3,720 acres of desert scrub, 23,814 acres of grassland (including native and non-native grassland), 1,032 acres of montane coniferous forest, 180 acres of playas and vernal pools, 1,086 acres of riparian scrub, 1,122 acres of Riversidean sage scrub, 66 acres of open water, and 5,382 acres of woodland.

Within the areas designated for Agriculture, impacts to natural vegetation communities would include the following: 2,600 acres of chaparral, 935 acres of coastal sage scrub, 5 acres of desert scrub, 3,040 acres of grassland (including native and non-native grassland), 25 acres of meadows and marshes, 515 acres of montane coniferous forest, 254 acres of playas and vernal pools, 95 acres of riparian scrub, 130 acres of Riversidean sage scrub, 70 acres of open water, and 160 acres of woodlands.

Impacts within the Community Development designated areas would include approximately 48,241 acres of chaparral, 1,092 acres of cismontane alkali marsh, 42,532 acres of coastal sage scrub, 5,530 acres of desert scrub, 74,841 acres of grassland (including native and non-native grassland), 57 acres of meadows and marshes, 3,097 acres of montane coniferous forest, 2,242 acres of playas and vernal pools, 4,180 acres of riparian scrub, 3,249 acres of Riversidean sage scrub, and 3,591 acres of open water and 2,308 acres of woodland.

Included within the 439,470 acres of Open Space designations are existing public/quasipublic lands. A variety of management activities would continue to occur under the No

Impacts resulting from development activities are currently subject to a variety of local State and federal regulatory processes. Under the No Project Alternative, these existing processes, and the resulting project modifications and mitigation, are anticipated to result in some conservation of habitats and species within the MSHCP Area. Biological resources that are afforded the greatest level of protection under existing regulations and policies are those species that are listed as threatened or endangered and those species and habitats associated with wetland systems, as further discussed below.

The following is a summary of existing environmental regulations that are currently applied in western Riverside County and would continue to be applied under the No Project Alternative:

Federal Regulations

Federal Endangered Species Act (FESA). Section 7 of the FESA stipulates that a federal action such as issuance of a permit under the Clean Water Act by the U.S. Army Corps of Engineers requires the federal agency enter into consultation with the USFWS to ensure that the federal action is not likely to jeopardize the continued existence of any federally-listed endangered or threatened species or result in the destruction or adverse modification of habitat of such species which is determined to be critical (Section 7[a][2]).

To facilitate compliance with the requirements of Section 7[a][2]), the federal agency shall request a list of endangered, threatened, candidate (now known limited to Category 1 candidate species), or proposed species in the area of the Proposed Action. If these species may be present, the federal agency prepares a Biological Assessment to identify any endangered or threatened species that are likely to be within the area subject to take authorization by the action (Section 7[c]) and whether a formal consultation with the USFWS is required. If a formal consultation is required, the USFWS reviews the Biological Assessment and issues a Biological Opinion determining whether the action is likely to jeopardize the continued existence of any endangered or threatened species or result in the destruction or adverse modification of habitat of such species which is determined to be critical. The Biological Opinion also may recommend reasonable and prudent alternatives that are consistent with the intended purpose of the action (project) and would allow the action to proceed without violation of Section 7(a)(2).

Section 9 of the FESA prohibits the taking of species listed by the USFWS as threatened or endangered. As defined by the FESA, “taking” means “to harass, harm, pursue, hunt, shoot, wound, kill, trap, or capture or collect, or attempt to engage in such conduct.” “Harass” and “harm” are further defined in federal regulation and case law as follows:

Harass means an intentional or negligent act or omission which creates the likelihood of injuring wildlife by annoying it to such an extent as to significantly disrupt normal behavioral patterns which include, but are not limited to, breeding, feeding, or sheltering (50 CFR 17.3).

Harm means an act which actually kills or injures wildlife. Such acts may include significant habitat modification or degradation where it actually kills or injures wildlife by significantly impairing essential behavior patterns, including breeding, feeding, or sheltering (50 CFR 17.3).

With respect to listed plants, the FESA makes it unlawful to:

Remove and reduce to possession any species from areas under federal jurisdiction;
Maliciously damage or destroy any such species on such area; or
Remove, cut, dig up, or damage or destroy any such species on any other area in knowing violation of any law or regulation in any State or in the course of any violation of a State criminal trespass law.

FESA protection for threatened plants is substantially the same as that given to endangered plants, except that the seeds of threatened plants may be collected.

Section 10(a) of the FESA provides for takings that are incidental to, but not the purpose of, otherwise lawful activities. Similar provisions also are found under Section 7 for actions by federal agencies.

Under Section 10(a)(1)(B), USFWS (via powers delegated by the Secretary of the Interior) is authorized to approve “incidental take” permits provided that the applicant has met certain conditions. As described in the Code of Federal Regulations (CFR) and Draft Conservation Planning Guidelines prepared by the USFWS, the application for such permits must be submitted on a specific form and must be accompanied by an HCP that contains the following information:

The impact that likely will result from the proposed taking of the species;
Steps the applicant will take to monitor, minimize, and mitigate such impacts;
The level and source of funding available to implement such steps;
Procedures that will be used to deal with unforeseen circumstances;
The names of the responsible party or parties;
Alternatives to the taking and the reasons why they were not pursued; and
Other measures that may be required by the USFWS as necessary or appropriate.

The application is submitted to the Regional Director of the USFWS who, after a public comment period, must issue the permit if it is found that:

The taking will be incidental to an otherwise lawful activity;
The applicant will, to the maximum extent practicable, minimize and mitigate the impacts of the taking;
The applicant will ensure that adequate funding for the conservation plan and procedures to deal with unforeseen circumstances will be provided;
The taking will not appreciably reduce the likelihood of the survival and recovery of the species in the wild;
The applicant will ensure that other measures (if any) that USFWS may require as being necessary or appropriate will be met; and
USFWS is assured that the HCP will be implemented. (USFWS' practice has been to require a legally binding “implementing agreement” signed by the permittee and the USFWS in which actions identified in the HCP are presented in the form of a legal contract.)

Prior to approval of the HCP, the USFWS must conduct an internal consultation in accordance with Section 7 of the FESA. USFWS also must comply with the environmental review requirements of the National Environmental Policy Act (NEPA), which requires that the potential effects of a major federal action be analyzed in a written statement (Environmental Assessment [EA] and a Finding of No Significant Impact [FONSI] or an Environmental Impact Statement [EIS], depending on the project and its impacts).

Federal Clean Water Act. Section 404 of the Clean Water Act, which is administered by the U.S. ACOE, regulates the discharge of dredged and/or fill material into “waters of the United States.” The term “waters of the United States” generally sets forth the jurisdiction of the U.S. ACOE and is defined in 33 CF

All navigable waters (including waters subject to the ebb and flow of the tide);
All interstate waters and wetlands;
All other waters such as intrastate lakes, rivers, streams (including intermittent streams), mudflats, sandflats, wetlands, sloughs, prairie potholes, wet meadows, playa lakes, or natural ponds, the use, degradation or destruction of which could affect interstate or foreign commerce;
All impoundments of waters mentioned above;
All tributaries of waters mentioned above;
The territorial seas; and
All wetlands adjacent to waters mentioned above.

R Part 328 as:

Wetlands are further defined in 33 CFR 328.3(b) as:

Those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support . . . a prevalence of vegetation typically adapted for life in saturated soil conditions.

The vegetation, soils, and hydrology of a wetland are further characterized in the manual used by the U.S. ACOE as normally meeting the following three criteria:

More than 50 percent of the dominant plant species at the site must be typical of wetlands (i.e., rated as facultative or wetter in the National List of Plant Species That Occur in Wetlands);
Soils must exhibit physical and/or chemical characteristics indicative of permanent or periodic saturation (e.g., a greyed color, or mottles with a matrix of low chroma indicating a relatively consistent fluctuation between aerobic and anaerobic conditions); and
Hydrology characteristics must indicate that the ground is saturated to within 12 inches of the surface for at least 5 percent of the growing season during a normal rainfall year.

The permitting process entails consultation with federal agencies, public notice, and preparation of a project alternatives analysis in accordance with guidelines issued by the U.S. Environmental Protection Agency (EPA). EPA's guidelines are used as the primary environmental criteria for evaluating the necessity of the proposed activity and for determining the least damaging feasible alternative and/or appropriate mitigation for unavoidable impacts. In accordance with the provisions of Section 404, Fish and Wildlife Coordination Act, and, if federally listed species are present, Section 7 of the FESA, U.S. ACOE also is required to consult with the USFWS prior to acting on the permit.

State Regulations

California Endangered Species Act (CESA). Section 2080 of CESA prohibits the import, export, take, possession, purchase, or sale of listed species unless explicitly authorized by other provisions of the law. Take is defined as to “hunt, pursue, or kill or attempt the same.” Section 2081 of the CESA authorizes the CDFG to enter into Memorandums of Understanding (MOUs) with persons, universities, zoological gardens, other institutions, and public agencies to incidentally take, posses, import, or export State-listed threatened and endangered species. A 2081 MOU is a legal contract with CDFG regarding the implementation of conservation and mitigation measures. Section 2053 of the CESA states that “. . . it is the policy of the State that State agencies should not approve projects as proposed which would jeopardize the continued existence of any endangered species or threatened species or result in the destruction or adverse modification of habitat essential to the continued existence of those species, if there are reasonable and prudent alternatives available with conserving the species or its habitats which would prevent jeopardy.”

California Fish and Game Code. Sections 1600-1603 of the California Fish and Game Code regulate all diversions, obstructions, or changes to the natural flow of bed, channel, or bank of any river, stream, or lake in California that supports fish or wildlife. “Stream” is defined in CDFG regulations as:

A body of water that flows at least periodically or intermittently through a bed or channel having banks and supporting fish or other aquatic life. This includes water courses having surface or subsurface flow that supports or has supported riparian vegetation.

Under State law, CDFG must be contacted for a streambed alteration agreement for any activity that may impact a streambed or wetland. CDFG has maintained a “no net loss” policy regarding potential impacts and traditionally has required replacement of wetlands on at least an acre-for-acre (1:1) basis. In practice, replacement ratios are typically higher than 1:1 to compensate for the immediate loss, replacement time, and inherent failures of mitigation attempts.

Local Regulations

California Environmental Quality Act (CEQA). The County of Riverside and each of the 14 cities, as well as special districts, and other public entities with autonomous land use authority are subject to the environmental review requirements of CEQA. CEQA requires that any discretionary action carried out by the decision-making authority (Lead Agency) be subject to review for potential adverse impacts to the environment. Where the Lead Agency finds that a project or activity could result in a potentially significant impact, it is required to develop and implement mitigation measures to reduce or eliminate that impact. The Lead Agency determines the threshold of significance for an impact and is responsible for ensuring that mitigation measures are feasible and are implemented by the appropriate responsible party. CEQA mitigation has the ability to contribute to conservation by requiring modifications to projects, and/or mitigation for adverse impacts through setting aside land, either on-site or off-site. Such conservation would occur on a project-by-project basis.

Other Land Use-Related Regulations

The County of Riverside and each of the 14 cities in the MSHCP Area maintain a variety of development regulations contained in their respective zoning ordinances, municipal codes, General Plans, and other policies and development standards. Such regulations, policies, and standards have the ability to contribute to conservation through restrictions on development of areas with steep slope, sensitive habitat, and other natural constraints. Conservation of land through these mechanisms is not specifically designed to conserve habitat for sensitive species, and is implemented on a project-by-project basis.

Impact Summary

Conservation of species and habitats provided through mitigation and compensation under the existing regulatory framework would likely result in a pattern of conservation that is fragmented and managed in a piecemeal fashion. There would not be a coordinated system of linkages provided to connect Conservation Areas, and the ability to provide linkages through project-by-project mitigation may be precluded over time through continued development.

Although the aforementioned regulations and policies would continue to be applied throughout the MSHCP Area in the absence of a comprehensive MSHCP, history has demonstrated that application of these regulations and policies would not avoid the decline of species in the MSHCP Area that has resulted in increased listings of species in recent years. Based on historic trends, it is anticipated that under the No Project/No MSHCP Alternative, new species would continue to be listed in the future, and regulation of those species and their habitats would be applied under the current regulatory processes.

Therefore, the No Project Alternative would have significant biological impacts under each of the thresholds of significance.

Summary of Analysis

Proposed MSHCP

Vegetation Communities. Because of features incorporated into the proposed MSHCP, impacts to sensitive vegetation communities are reduced to less than significant levels; with exception to impacts to native grasslands, which will remain a significant and unavoidable impact.

Listed Covered Species. With the combination of impact reduction features incorporated into the Proposed Project, including reserve configuration, adaptive management and monitoring, and species survey and avoidance/minimization policies, the Project's impacts to Listed Covered Species would be less than significant.

Non-Listed Covered Species. With the combination of impact-reduction features incorporated into the proposed project, including reserve configuration adaptive management and monitoring, and species survey and avoidance/minimization policies, impacts to Non-Listed Covered Species would be less than significant.

Non-Covered Species. Conservation provided under the MSHCP could potentially benefit Non-Covered Species that occur within the MSHCP Conservation Areas. However, impacts are considered to be significant due to the lack of adequate data supporting conservation of these species.

Cores and Linkages. The MSHCP provides for the movement of native resident and migratory species and for genetic flow identified for Covered Species. Therefore, impacts related to cores and linkages resulting from the Plan are considered less than significant.

Relationship to Adopted or Approved HCPs and NCCPs. As shown in Figure 4.1.2, Regional MSHCP Context, the Additional Reserve Lands and existing public/quasipublic lands do not conflict with the provisions of any adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or State habitat conservation plan, either within the MSHCP Plan Area or in the surrounding region. Rather, the MSHCP will complement other regional planning efforts, including those that are currently underway but have not yet been approved.

Edge Effects. Implementation of features incorporated into the Plan to control edge effects would reduce impacts to a level that is less than significant.

Vegetation Communities. Implementation of features incorporated into the Plan would reduce impacts to most of the vegetation communities to less than significant levels. However, for the sensitive upland communities, due to the large percentages of chaparral (52%), coastal sage scrub (78%), desert scrub (91%), grassland (85%) (including native and non-native grassland), and Riversidean alluvial fan sage scrub (74%) potentially within the area subject to take authorization under this alternative, significant impacts to these vegetation communities would occur even with application of the minimization measures.

Listed Covered Species. A reduced level of conservation of suitable habitat and species localities at Temescal Wash, Vail Lake, Temecula Creek, Wilson Creek, Anza Valley, Badlands, and Reche Canyon is anticipated under this alternative. Areas such as the Jurupa Mountain, Cactus Valley, and a number of linkages, including Warm Springs Creek, Tenaja Corridor, Tule Creek, Cahuilla Creek, Garden Aire Wash, and Noble Creek, previously identified for inclusion as part of the MSHCP Conservation Area, would be excluded under this alternative. However, with application of the narrow endemic policy, additional survey needs policy and wetlands policy, as well as reserve assembly and configuration, direct and indirect impacts to Listed Covered Species would be reduced to less than significant levels.

Non-Listed Covered Species. A reduced level of conservation of suitable habitat and species localities at Temescal Wash, Vail Lake, Temecula Creek, Wilson Creek, Anza Valley, Badlands, and Reche Canyon is anticipated under this alternative. Areas such as the Jurupa Mountain, Cactus Valley, and a number of linkages, including Warm Springs Creek, Tenaja Corridor, Tule Creek, Cahuilla Creek, Garden Aire Wash, and Noble Creek, previously identified for inclusion as part of the MSHCP Conservation Area, would be excluded under this alternative. However, adequate conservation for the Non-Listed Covered Species is provided with this alternative. It should be noted that certain species that are covered under the MSHCP Project are not covered under this alternative.

Non-Covered Species. Any conservation benefits that would accrue to these species as a result of the MSHCP would be reduced under this alternative due to the reduction in overall Conservation Area. Impacts to non-covered species would remain significant.

Cores and Linkages. Issuance of take authorization would result in significant impacts to the proposed and existing cores and linkages depicted in Figure 4.1.3.

Relationship to Adopted or Approved HCPs and NCCPs. Significant impacts are anticipated due to the failure to maintain critical linkage components present in other adopted HCPs and NCCPs.

Edge Effects. The same features incorporated in the MSHCP to minimize edge effects would be incorporated in this alternative, including the standard BMPs; Land Use Guidelines Pertaining to the Urban/Wildlands Interface; and siting, design, construction, operations, and maintenance guidelines for Covered Activities and Allowable Uses. However, significant edge effects would remain even with implementation of these minimization measures because of the reduction in cores and linkages under this alternative when compared with the proposed MSHCP.

Vegetation Communities. Inclusion of substantial acreages of wetland vegetation communities within the MSHCP Conservation Area under this alternative, and implementation of the riparian, riverine, and vernal pool policy incorporated in the MSHCP, would reduce identified impacts to wetland vegetation communities to a level below significance. Impacts to most other vegetation communities would likewise be reduced to a level below significance. However, due to the large percentages of coastal sage scrub (59%), grassland (78%) (including native and non-native grassland), and desert scrub (91%) potentially within the area subject to take authorization within the take authorized area, significant impacts to these vegetation communities would occur even with application of the minimization measures.

Listed Covered Species. With application of the narrow endemic policy, additional survey needs policy, and riparian, riverine, and vernal pool policy, as well as Reserve Assembly and configuration, impacts to Listed Covered Species would be less than significant.

Non-listed Covered Species. With application of the narrow endemic policy, additional survey needs policy and riparian, riverine, and wetlands policy, as well as Reserve Assembly and configuration, impacts to Non-Listed Covered Species would be reduced to less than significant levels.

Non-Covered Species. Any conservation benefits that would accrue to species as a result of the MSHCP and the Listed, Proposed, and Strong Candidate Species Alternative would likely be somewhat reduced under this alternative, due to the reduction in overall Conservation Area. Impacts to non-covered species would remain significant.

Cores and Linkages. Issuance of take authorization would result in significant impacts to the proposed and existing cores and linkages depicted in Figure 4.1.3.

Relationship to Adopted or Approved HCPs and NCCPs. Significant impacts are anticipated due to the failure to maintain critical linkage components present in other adopted HCPs and NCCPs.

Edge Effects. Significant edge effects would remain even with implementation of these minimization measures for all of the existing cores and linkages, due to the absence of important linkages, reduction in core areas, and increased human interaction with wildlife.

Existing Reserves Alternative

Vegetation Communities. Impacts to most vegetation communities would be less than significant with incorporation of wetland policies. However, due to the large percentages of chaparral (52%), coastal sage scrub (78%), desert scrub (91%), grassland (85%) (including native and non-native grassland), and Riversidean alluvial fan sage scrub (74%) potentially within the area subject to take authorization under this alternative, significant impacts to sensitive natural vegetation communities would occur even with application of the minimization measures.

Listed Covered Species. Because conservation would only occur on Existing Reserves, take authorization would be granted in areas of suitable habitat and known species Non-Listed Covered Species. This alternative would not include coverage for the Covered Activities described for the MSHCP. Therefore, the Existing Reserves Alternative would not result in any impacts to Non-Listed Covered Species from Covered Activities. Under this alternative, significant impacts to the Non-Listed Covered Species would occur due to the fact that no additional lands would be conserved as habitat for these species.

Non-Covered Species. Any conservation benefits that would accrue to species as a result of the proposed MSHCP; the Listed, Proposed, and Strong Candidate Species Alternative; and the Listed and Proposed Alternative would be reduced under this alternative, due to the reduction in overall Conservation Area. These impacts remain considered significant and unavoidable.

Cores and Linkages. Issuance of take authorization would result in significant impacts to the proposed and existing cores and linkages depicted in Figure 4.1.3.

Relationship to HCPs and NCCPs. Significant impacts are anticipated due to the failure to maintain critical linkage components present in other adopted HCPs and NCCPs.

Edge Effects. Significant edge effects would occur under this alternative to all the existing cores and linkages (as identified in Table 4E).

No Project Alternative

No significant effects associated with take authorization would occur under this alternative. However, significant effects associated with existing ongoing development, land use, and regulatory practices would continue to occur under this alternative.

4.1.5 Mitigation Measures

Under all alternatives with the exception of the No Project Alternative, the management and monitoring programs incorporated in the MSHCP would be implemented to mitigate to the extent feasible significant effects remaining after application of minimization measures incorporated in the MSHCP. Minimization measures are described in the Impact Analysis discussion for each alternative. For the purpose of analysis, it is assumed that the management and monitoring programs for the alternatives would be implemented according to the approaches and level of effort described in the Sections 5.0, 6.6, and 8.0 of the MSHCP, Volume I. The generalized management and monitoring activities would occur for all alternatives within the MSHCP Conservation Area identified for each particular alternative. The species-specific management and monitoring activities described in Section 5.0 of the MSHCP would be directed only toward the Covered Species identified for each particular alternative.

Aside from the features which have already been incorporated into the Plan (and each of the criteria-based reserve alternatives), no mitigation is available to reduce any of the identified significant impacts.

4.1.6 Level of Significance after Mitigation

MSHCP Proposed Project

Implementation of mitigation measures identified above would reduce identified impacts to a level below significance for all impacts except those associated with Non-Covered Species. Impacts to Non-Covered Species are significant and not mitigated.

Listed, Proposed, and Strong Candidate Species Alternative

Impacts to Non-Covered Species would remain significant. Due to the less robust reserve configuration and greater magnitude of take, significant impacts to the cores and linkages identified for this alternative would remain significant even after implementation of mitigation measures identified above.

Listed and Proposed Species Alternative

Existing Reserves Alternative

Due to the less robust reserve configuration and greater magnitude of take, significant impacts to the vegetation communities, Listed-Covered Species, Non-Listed Covered Species, Non-Covered species, and cores and linkages identified for this alternative would remain significant even after implementation of mitigation measures identified above.

No Project Alternative

The No Project Alternative would result in significant unmitigable impacts to habitats and species, due to the lack of adequate conservation and management of natural vegetation communities, and the lack of an adequate reserve configuration.

4.2 Agricultural and Extractive Resources

4.2.1 Agricultural Resources

In terms of dollar value, agriculture is today the largest industry in Riverside County, providing employment for a significant portion of the County's population. Currently, agriculture faces continuing pressure from urbanization, foreign competition, and rising production costs. Despite these pressures, those areas which remain in agricultural production represent a significant open space and economic resource for the County.

MSHCP Conservation Area. The MSHCP Conservation Area will contain approximately 500,000 acres comprised of the following: 1) conservation of existing publicly owned lands, 2) voluntary acquisition of privately held lands by the Cities, the County, or other Permittees, 3) voluntary acquisition of privately held lands by state and/or federal agencies, and 4) contributions from public and private development.

The MSHCP Conservation Area will be assembled through conservation of approximately 347,000 acres of existing public/quasi-public lands (PQP), and the voluntary acquisition of approximately 153,000 acres privately held lands by the cities, County, or other Permitees. The 153,000 acres of Additional Reserve Lands (ARL) will be drawn from the 310,000 acre Criteria Area.

Existing Agricultural Operations (on parcels included in the Agricultural Operations Database that do not require a County discretionary permit, certain City ministerial permits, or other discretionary authorization) will receive incidental Take Authorization and will not be required to implement MSHCP mitigation requirements. After the effective date of the proposed MSHCP, if Section 7.3.3 of the MSHCP is implemented, the Take Authorization may be applied to up to 10,000 acres of new agricultural lands within the Criteria Areas during the term of the proposed MSHCP, upon:

• Submission and approval of an Agricultural Grading/Clearing Exception Form as set forth in Riverside County Ordinance No. 457; and either

• Execution of a Williamson Act contract covering the new Agricultural Land; or

• County approval of any other mechanism providing equal or better assurance that the proposed new agricultural lands will be used for agricultural production.

In all instances, issuance of a Certificate of Inclusion (or other mechanism acknowledging Take Authorization) will occur prior to incidental take authorization. The County will process all Agricultural Grading/Clearing Exception Forms pursuant to the requirements of Riverside County Ordinance No. 457.

Existing Farmland and Farmland Designations Farmland Categories within the MSHCP Plan Area

Various methods were utilized to identify the extent, and location, and status of agricultural land within the proposed MSHCP Plan Area. This EIR/EIS analyzes potential impacts to agricultural resources within the MSHCP Plan Area in three categories: These methods, distinguish between the different methods that have been used to identify farmland Designated Farmland, Existing Agricultural Operations, and land zoned or designated for agricultural use under the Cities' existing or the County's Draft General Plans or subject to a Williamson Act contract within western Riverside County and are summarized below. Because the extent, configuration, and status (farmed/fallow) of land within each category may vary, and because the differing categories may overlap, separate baselines were identified for each category.

State Farmland Designations. Utilizing data from the U.S. Department of Agriculture (USDA) Natural Resource Conservation Service (NRCS) soil survey and current land use information, the California Department of Conservation, Farmland Mapping and Monitoring Program (FMMP), compiles important farmland maps for each county within the State. Maps and statistics are produced biannually using a process that integrates aerial photo interpretation, field mapping, a computerized mapping system, and public review. These maps categorize land use into eight mapping categories and represent an inventory of agricultural soil resources within the county. A total of 383,650 acres in western Riverside County has been recognized as agriculturally significant important by either State or local authorities. This sum includes 99,090 acres designated by the Department of Conservation's Farmland Mapping and Monitoring Program under its soils mapping program as Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (“Designated Farmland”). Of the 99,090 acres of Designated Farmland, 48,099 acres are Prime; 29,680 acres are Unique; and 21,311 acres are Statewide Important. The EIR/EIS utilizes 99,090 acres as the baseline for determining whether there are impacts to Designated Farmland. The 99,090-acre baseline represents se totals are inclusive of all land within the pre-project amount of Designated Farmland throughout the MSHCP Plan Area, including land within western Riverside County, within cities and unincorporated areas, and within existing reserves. Of the 99,090 acres of Designated Farmland within the MSHCP Plan Area, 18,653 are located within the Criteria Area, from which the Additional Reserve Lands will be drawn and the reserves will be assembled.

(An additional 284,560 acres have been designated as locally important (172,418 acres) or grazing land (112,142 acres). ) Riverside County has defined locally important farmlands to include:

• Those areas with soils that would be classified as Prime and Statewide but which lack available irrigation water;

• Lands planted to dryland crops of barely, oats, and wheat;

• Lands producing major corps for Riverside County but that are not listed as Unique crops. These crops are identified as returning $1 million or more on the 1980 Riverside County Agriculture Crop Report. Crops identified include permanent pasture (irrigated), summer squash, okra, eggplant, radishes, and watermelons;

• Dairylands, including corrals, pastures, milking facilities, and hay and manure storage areas if accompanied by permanent pasture or hayland of 10 acres or more;

• Lands identified by city or county ordinance as Agricultural Zones or Contracts. This includes Riverside City “Proposition R” lands; and

• Lands planted to jojoba that are under cultivation and are of producing age.

Grazing land is defined as land on which existing vegetation is suited to the grazing of livestock.

Lands planted to dryland crops, land producing crops, dairy lands, and lands planted to jojoba are analyzed under the threshold of significance relating to Existing Agricultural Operations. Lands identified by City or County ordinance as agricultural zones are analyzed in the discussion of lands zoned or General Plan-designated for agricultural use. Therefore, the Draft EIR/EIS' analysis already encompasses impacts to Locally Important Farmlands under the thresholds of significance established by the Lead Agencies and utilized in the Draft EIR/EIS. Consequently, the Draft EIR/EIS did not engage in further analysis of potential impacts on Locally Important Farmlands.

While a farmland designation may be assigned to a particular area, it does not necessarily follow that agricultural operations occur there. By intersecting the GIS data layers that depict existing agricultural uses and Designated Farmland, it is possible to discern the amount of Designated Farmland that is actually farmed. Based on this exercise, 76,384 acres, or approximately 77 percent, of the Prime, Unique, and Statewide Important farmland within the MSHCP Plan Area is utilized for agricultural production. Table 4R identifies the amount of Prime, Unique, or Statewide Important (collectively, Designated Farmland) that exists throughout the MSHCP Plan Area, within The Criteria Area, and the amount that may would fall within the limits of the Proposed Action and each MSHCP alternative within the limits of the Proposed Action and each MSHCP alternative.

Based on this threshold, this EIR/EIS utilizes 90,090 acres as the baseline for Designated Farmland from which potentially significant impacts are assessed.

Active Existing Agricultural Operations Use. This document analyzes "agriculture" as a both a vegetation community and a land use. Active agricultural use is distinguishable from agricultural vegetation. Active agricultural use refers to commercial and residential agricultural operations. Agricultural operations are defined as the production of all plants (horticulture), fish farms, animals and related production activities, including the planting, cultivation and tillage of the soil, dairying, and apiculture; and the production, plowing, seeding, cultivation, growing, harvesting, pasturing and fallowing for the purpose of crop rotation of any agricultural commodity, including viticulture, apiculture, horticulture, and the breeding, feeding and raising of livestock, horses, fur-bearing animals, fish, or poultry and all uses conducted as a normal part of such operations; provided such actions are in compliance with all applicable laws and regulations.

In contrast, agricultural vegetation is one of four broad vegetation communities analyzed in the MSHCP and in the Biological Resources section of this document. The vegetation map and agricultural vegetation acreage figure cited in the MSHCP which was incorporated into the proposed MSHCP was created by Pacific Southwest Biological Services and mapped by KTU+A in 1995. This map was created by compiling all known vegetation information within the Plan Area. These data sources include biological survey reports, Weislander vegetation maps, satellite imagery and the Dangermond/RECON data set. Methods used to create and interpret vegetation data included aerial photograph interpretation, edge matching, digitizing and geographically registering the data. In areas of concern, ground truthing occurred. Vegetation types were classified according to Holland. The Holland classification system classifies vegetation categories and recognizes "agriculture" as crops, orchards, vineyards or similar uses. The Holland classification does not encompass typically agriculture-related uses such as dairies, corrals, or feedlots as "agriculture." An analysis of agriculture as a vegetation community is provided in Table ES-A, and impacts to vegetation communities are analyzed in Section 4.1.4 of this document. Based on the 1995 vegetation mapping, 169,470 169,480 acres in western Riverside County throughout the MSHCP Plan Area are identified as agricultural lands.

Agricultural lands uses include areas occupied by dairies, and livestock feed yards and related uses; agricultural production/storage areas; and areas that have been tilled for use as croplands, vineyards, groves, or orchards. An interpretation of land use undertaken during the preparation of the Riverside County Existing Setting Report (1999) for the 2002 Riverside County General Plan identified approximately 161,792 acres (amounting to 13 percent of the proposed MSHCP Plan Area) actively utilized for agricultural production. This interpretation was supported by field checks and a verification of land use. Of the 161,792 acres of active farmland in western Riverside County, up to 32,726 acres may be located within the Criteria Area from which the Additional Reserve Lands will be drawn. The largest areas of dairy and livestock feed yards are located north of San Jacinto and north of Juniper Flats in the communities of Lakeview, Mystic Lake, Nuevo, southeast Perris, Eastvale, Lake Norconian off Bellegrave Avenue, Norco, and in Glen Avon. Field croplands are mapped extensively throughout the Plan Area. The largest areas are around State Route 371 (SR-371) in the vicinity of Anza; in an east-west strip from Murrieta Hot Springs; through French Valley; Antelope Valley; Paloma Valley; Menifee Valley; Winchester; Domenigoni Valley to West Hemet; the Diamond Valley area; and in Eastvale. The largest area of grove/orchard use is in Santa Rosa East between Gavilan Mountain and Mesa de Colorado. Table 4S identifies the amount of land actively utilized for agricultural production that would may fall within the limits of the Proposed Action and each MSHCP alternative.

A discrepancy between The amount of "agricultural" acreage within western Riverside County the MSHCP Plan Area exists varies according to the unit of measurement that is used. The vegetation map and data derived from it are representative of vegetation community conditions at the time the vegetation study was prepared (1995), while the Riverside County Existing Setting Report is a (1999) more recent (1999) interpretation of land use. As its data is more recent Since this section of the EIR/EIS analyzes impacts to existing agricultural land uses, the agricultural acreage data identified in the Riverside County Existing Setting Report will be is used as the basis for analysis in this section of the EIR/EIS.

MSHCP Provisions Regarding Existing Agricultural Operations

The Take Authorization for Existing Agricultural Operations becomes effective upon the County's receipt of a properly executed Certificate of Inclusion and the inclusion of the operation into County's Existing Agricultural Operations Database. Provided requirements set forth in the MSHCP and its Implementing Agreement are met, Existing Agricultural Operations:

• Are exempt from the payment of mitigation fees or other mitigation measures; and

• May change agricultural crop type and continue to receive Take Authorization.

(The conversion from grazing or pastureland uses to a tilled crop represents a fundamental change in the biological value of the land use and therefore does not fall within the definition of Existing Agricultural Operations.) The Existing Agricultural Operations Database will be established on or before the effective date of the MSHCP. The MSHCP and its Implementing Agreement allow landowners 36 months (48 months for agricultural operations occurring on less than 40 acres) from the effective date of the MSHCP to provide evidence that supports the inclusion of land into the Existing Agricultural Operations Database.

Expansion of Existing Agricultural Operations or similar uses requiring a County or City discretionary permit, other discretionary authorization, or certain City ministerial permits will also receive Take Authorization, provided the requirements set forth in the MSHCP and Implementing Agreement are met. If the expansion requires a discretionary authorization and occurs within the Criteria Area, then the Criteria will be applied and appropriate mitigation imposed. Such projects will not be subject to the Criteria and mitigation requirements if construction and operation disturbance and impacts are confined solely to the existing building footprint (i.e., limited to those areas that have been recently and consistently disturbed and have little or no habitat value). If the expansion requires discretionary authorization and occurs outside the Criteria Area, then the Criteria will not be applied. However, the policies for the protection of Narrow Endemic Plant Species and Riparian/Riverine Areas and Vernal Pools requirements, and/or additional survey requirements forth the MSHCP shall be applied, if appropriate.

Inside the Criteria Area, the Take Authorization will be applied to a limited number of New Agricultural Lands to be used for Agricultural Operations (including the expansion of Existing Agricultural Operations not requiring a discretionary permit or other discretionary authorization) after the effective date of the Implementing Agreement and consistent with the goals of the MSHCP. The Take Authorization may be applied to up to 10,000 acres of new agricultural land within the Criteria Area during the term of the MSHCP. The Take Authorization shall apply to new agricultural lands, as allowed pursuant to the MSHCP, upon: 1) submission and approval of an Agricultural Grading/Clearing Exception Form as set forth in Riverside County Ordinance No. 457; and 2) either a) execution of a Williamson Act contract covering the New Agricultural Lands or b) County or City approval of any other mechanism providing equal or better assurance that the proposed new agricultural lands will be used for Agricultural Operations. In all instances, issuance of a Certificate of Inclusion must occur prior to Take Authorization. This requirement shall not be applicable to projects: 1) currently within an agricultural zone established by Ordinance No. 348, and 2) whose building footprint will be wholly within property previously tilled as part of the Existing Agricultural Operations. Take Authorization may be applied to unlimited new lands for Agricultural Operations outside the Criteria Area. New agricultural lands shall be exempt from the payment of any impact mitigation fee or other mitigation measures imposed by the MSHCP, except as set forth in the Implementing Agreement. The cap on New Agricultural Lands acreage is intended to accommodate expansion of agricultural operations while providing a mechanism for accounting for Take within the Criteria Area. It is not to be interpreted as restricting the expansion of agricultural land uses in the MSHCP Plan Area.

Agricultural Zone(s) or General Plan Designation(s). In addition to zoning and General Plan designated land in the unincorporated areas of Riverside County, seven Cities (Banning, Beaumont, Corona, Hemet, Moreno Valley, Norco, and San Jacinto) within western Riverside County the MSHCP Plan Area have established agricultural zones and/or have designated agriculture as a distinct General Plan land use. Throughout western Riverside, 38,280 acres are specifically designated or zoned for agricultural use.

The proposed Riverside County General Plan (also known as the "Draft General Plan" or the "General Plan Update") identifies agriculture as a "Foundation Component." In the proposed General Plan, "Foundation Components" are considered to be the first tier of land uses and describe the overall nature and intent of the Draft General Plan. The "Agriculture" Foundation Component consists of one area plan land use designation of the same name. The Agriculture (AG) land use designation has been established to help conserve productive agricultural lands within the County. These include row crops, nurseries, citrus groves and vineyards, dairies, ranches, poultry and hog farms, and other agricultural related uses. Within the unincorporated areas of western Riverside County, 30,553 30,610 acres have been specifically designated for agricultural uses under the "Agriculture" Foundation Component. Table 4T details the amount of land specifically zoned or designated for agricultural uses under the Cities' existing General Plans or the "Agriculture" Foundation Component of the County's General Plan Update. Under the Cities' existing and the County's Draft General Plan (General Plan Update), a total of 38,223 acres (Table 4T) within the MSHCP Plan Area may be designated in the General Plan(s)/zoned for agricultural uses. Of the 38,223 acres of land within the MSHCP Plan Area that are zoned or designated for agricultural use under the Cities' existing and the County's Draft General Plans, 16,947 acres will be located within the Criteria Area from which the Additional Reserve Lands will be drawn.

As designated Under the Cities' and the County's current General Plans, 84,364 acres within the MSHCP Plan Area are specifically General Plan designated or zoned for agricultural uses. By intersecting the GIS data layers that depict existing agricultural uses and land zoned or general plan designated for agricultural uses, it is possible to discern the amount of land zoned or otherwise designated for agricultural use that is actually farmed. Based on this exercise, 33,927 acres of the land zoned or General Plan designated for agricultural uses within the MSHCP Plan Area is actively utilized for agricultural production. Of the 84,364 acres of land in western Riverside County currently the MSHCP Plan Area zoned or General Plan designated for agricultural uses under the Cities' and County's existing GPS, up to 16,947 acres are located within the Criteria Area from which the Additional Reserve Lands will be drawn. Table 4U details the amount of land currently designated or zoned for agricultural uses that would may fall within the limits of the Proposed MSHCP and each alternative.

Existing Policies and Regulations

Williamson Act Land Preserves. In 1965, the California Land Conservation Act, also known as the Williamson Act, was adopted. This voluntary program allows property owners to have their property assessed on the basis of its agricultural production rather than at the current market value. The property owner is thus relieved of having to pay higher property taxes as long as the land remains in agricultural production. The purposes of the Act is are to encourage property owners to continue to farm their land, and to prevent the premature conversion of farmland to urban uses. Participation requires that the area consist of 100 contiguous acres of agricultural land under one or more ownerships. Statewide, in 2001, 16.3 million acres, representing approximately one-half of the State's farmland (and one-third of the State's privately owned land), were enrolled under Williamson Act contracts.

Upon approval of an application by the Board of Supervisors local governing body with land use authority, the an agricultural preserve is established, and the land within the preserve is restricted to agricultural and compatible uses for 10 years. Williamson Act contracts are automatically renewed annually for an additional one-year period, unless the property owner applies for non-renewal or early cancellation. Nonrenewal initiations are requested either by the landowner or the local government and are often filed in anticipation of converting farmland to other uses. In 2001, Riverside County ranked fourth in the State in the amount of land (1,526 acres) on which nonrenewal was initiated. Throughout the County in 2001, Williamson Act contracts expired on 539 acres of farmland on which nonrenewals were initiated.

The Williamson Act also contains limited provisions for cancellation of contracts. A cancellation of a Williamson Act contract is the immediate termination of an enforceable restriction by a landowner. A Williamson Act contract cancellation requires payment of a cancellation fee as well as approval by the County Board of Supervisors or City Council. Specific findings regarding the non-viability of the agricultural use must be made, and a substantial penalty for the cancellation is assessed. Because of the rigorous findings required for such approvals, cancellations typically amount to a small fraction of total contract terminations each year. In 2001, Riverside County also ranked fourth in the State in the amount (55 acres) of Williamson Act contract cancellations.

Williamson Act contracted land may be acquired for a wide range of public uses. Public acquisition through eminent domain by a public agency results in the immediate termination of an enforceable contract. Wildlife habitat, water resource management, public open space, and public schools are common alternative uses for publicly acquired contracted land. In 2001, a total of 87 acres of contracted land throughout the County was publicly acquired. To exercise its right to take land under Williamson Act contract, the public agency may be required to make specific findings and notifications.

Based on figures obtained from the California Department of Conservation, Division of Land Resources Protection, 62,668 acres within the whole of Riverside County were under Williamson Act protection in 2001. Of this amount, 55,954 acres were Prime farmland, while 6,714 acres were located on non-prime farmland.

In 1998, the State Legislature established the Farmland Security Zone (FSZ) provision of the Williamson Act. An FSZ is an area created within an agricultural preserve which offers landowners greater property tax reduction in return for an initial contract term of twenty years, with renewal occurring automatically every year. For the purpose of property assessment, land restricted by an FSZ contract is valued at 65 percent of its Williamson Act valuation. According to the State's 2002 Williamson Act Status Report, no land within Riverside County is currently covered under an FSZ contract.

County of Riverside Ordinance No. 509. This ordinance establishes uniform rules which apply to agricultural preserves.

Impacts

Criteria for Determining Significance. The Proposed Action will have a significant on agricultural resources if its implementation would result in the conversion of agricultural land to non-agricultural uses. The thresholds criteria listed below are derived from Appendix G of the State CEQA Guidelines and were used by the Lead Agencies to determine the significance of impacts related to agricultural resources. Impacts would be significant if the implementation of the Proposed Action Project or Alternative would:

Conflict with existing agricultural designations for land within the MSHCP Plan Area or a Williamson Act contract;
Result in the conversion of Existing Agricultural Operations to non-agricultural use;
Result in the conversion of Designated Farmland (Prime, Unique, or Statewide Important farmland (collectively, “Designated Farmland”) as shown on maps prepared by the Farmland Mapping and Monitoring Program, to non-agricultural uses; or
Involve other changes in the existing environment which, due to their location or nature, could result in the conversion of Designated Farmland to non-agricultural use.

Impacts of the Alternative Scenarios

The following discussions assess potential impacts to the various categories of agricultural land (e.g., Existing Agricultural Operations, land zoned or General Plan designated for agricultural use or subject to a Williamson Act contract, or Designated Farmland). Because the extent, configuration, and status (farmed/fallow) of land within each farmland category may vary, the analysis utilizes different baselines for each category. Using these varying baselines, this document analyzes the potential impacts to each category of agricultural operations that would result from implementation of the proposed MSHCP and its various alternatives.

Existing Agricultural Designations and Williamson Act Contracts Impacts to Existing Agricultural Operations.

Based on the thresholds identified above, impacts would be significant if the implementation of the Proposed Action or any Alternative would result in the conversion of Existing Agricultural Operations to non-agricultural uses. Agricultural operations are defined as the production of all plants (horticulture), fish farms, animals and related production activities, including the planting, cultivation and tillage of the soil, dairying, and apiculture; and the production, plowing, seeding, cultivation, growing, harvesting, pasturing and fallowing for the purpose of crop rotation of any agricultural commodity, including viticulture, apiculture, horticulture, and the breeding, feeding and raising of livestock, horses, fur-bearing animals, fish, or poultry and all uses conducted as a normal part of such operations; provided such actions are in compliance with all applicable laws and regulations.

Proposed MSHCP. Of the 161,792 acres of active farmland within the proposed MSHCP Plan Area, 16,898 acres will fall may be included within the Conservation Area upon implementation of the Proposed Action. Under alternatives to the Proposed Action, the amount of active farmland within the Conservation Area ranges from 7,235 to 15,745 8,510 acres. The amounts of active agricultural land that will may fall within the Conservation Area under the proposed MSHCP and each alternative (and the change from existing conditions) are identified in Tables 4 UR-4 XU. As stated in Section 6.2 of the MSHCP document, "Take" Authorization will apply to those lands within MSHCP boundaries being used for Existing ongoing Agricultural Operations for at least one of the last five years preceding the effective date of the Implementing Agreement. Existing Agricultural Operations within the conservation Criteria Area are generally exempt from the payment of impact mitigation fees or other mitigation measures.

In order to verify the location of the Existing Agricultural Operations, the proposed MSHCP includes provisions for the creation of a database identifying "Existing Agricultural Operations" on or before the effective date of the proposed MSHCP. The "Existing Agricultural Operations Database" will include parcel numbers, acreage, ownership/operation names, and a map or other representation identifying parcels containing Existing Agricultural Operations. The information contained in the Existing Agricultural Operations Database will be submitted to the Wildlife Agencies on an annual basis. A Certificate of Inclusion (a ministerial action that verifies agricultural uses on a property) or other mechanism will be completed to obtain incidental take coverage for Existing Agricultural Operations, which will occur solely for the purpose of documenting acknowledgment of incidental take authorization.

Note: 1 A farmland designation may be assigned to a parcel of land but it does not necessarily follow that agricultural operations occur or are planned on that parcel.

Outside the Criteria Area, Existing Agricultural Operations may expand and new operations may commence indefinitely. Inside the Criteria Area, the expansion of Existing Agricultural Operations or similar use requiring a County discretionary permit, or other discretionary authorizations, or certain City ministerial permits (as set forth in the MSHCP) will not be subject to requirements of the proposed MSHCP if construction and operation disturbance is confined to the existing building footprint. Existing Agricultural Operations may change agricultural crop types and continue to receive Incidental Take coverage, provided all requirements outlined in Section 6.0 of the proposed MSHCP have been met. However, conversion from grazing or pastureland uses to a tilled crop does not fall within the definition of Existing Agricultural Operations.

As stated in Section 6.2 of the MSHCP, "Take" Authorization will apply to those lands within the MSHCP Plan Area that were being used for Existing Agricultural Operations for at least one of the last five years preceding the effective date of the MSHCP Implementing Agreement. Existing Agricultural Operations within the MSHCP Plan Area are exempt from the payment of impact mitigation fees or other mitigation measures. Because Existing Agricultural Operations are a Covered Activity and will be permitted to continue even within the Conservation Area (subject to provisions outlined in the proposed MSHCP), implementation of the proposed MSHCP will not will not significantly reduce the amount of land presently utilized for agricultural production or otherwise affect existing agricultural operations convert Existing Agricultural Operations into nonagricultural uses and no significant impact resulting from the conversion of active agricultural land to non-agricultural uses will occur.

Listed, Proposed, and Strong Candidate Species Alternative. This alternative was developed to depict a potential conservation scenario that would address listed, proposed, and strong candidate species. Implementation of the Listed, Proposed, and Strong Candidate Species Alternative may conserve a total of about 465,830 acres, including 346,530 acres within existing reserves and 119,300 acres of private land outside of existing reserves.

As stated in Table 4S, if this Alternative were implemented, 15,745 acres of the land currently utilized for agricultural production (9.7%) may be within the Conservation Area. As with the MSHCP, Existing Agricultural Operations would be a Covered Activity under this Alternative. Compared to the Proposed Action, this alternative decreases the amount of land potentially subject to conservation. However, because Existing Agricultural Operations would continue to be a Covered Activity under this Alternative, no significant impact resulting from the loss of active agricultural land would occur.

Note: 1 A farmland designation may be assigned to a parcel of land but it does not necessarily follow that agricultural operations occur or are planned on that parcel.

Listed and Proposed Species Alternative. This Alternative was developed to depict a potential conservation scenario that would address only the 32 species listed or proposed for listing, with less consideration of the broad-based NCCP biological concepts. Under this Alternative, a total of about 439,140 acres would be conserved, including 346,530 acres within existing reserves and 92,610 acres of private lands outside existing reserves.

As shown in Table 4S, approximately 15,178 acres of land currently utilized for agricultural production (9.4%) may fall within the Conservation Area under this alternative. Compared to the Proposed Action, this alternative would decrease the amount of active agricultural land potentially subject to conservation by up to 1,720 acres. However, because Existing Agricultural Operations would continue to be a Covered Activity under this Alternative, the Alternative does not affect Existing Agricultural Operations. Therefore, this Alternative will not cause any significant impact resulting from the loss of active agricultural land.

Note: 1 A farmland designation may be assigned to a parcel of land but it does not necessarily follow that agricultural operations occur or are planned on that parcel.

Existing Reserves Alternative. Under this Alternative, no additional conservation or management would occur within the existing reserves beyond that currently occurring or what might occur in the future with implementation of the U.S. Forest Service (USFS) Southern California Conservation Strategy. This Alternative is described in further detail in Section 2.5.

Table 4S identifies the amount of active agricultural land within unincorporated areas and cities that lie within existing reserves. As shown in Table 4S, under this Alternative, the 7,235 acres of active agricultural land located within existing reserves would receive Incidental Take Authorization. Existing Agricultural Operations within the existing reserves would be permitted to continue, and no additional private lands would be subject to conservation. Therefore, implementation of this Alternative will not result in any significant impacts to active agricultural land.

This Alternative would not conserve any additional land beyond that conserved in existing reserves. As this Alternative consists solely of existing reserves, compared to the proposed MSHCP, the amount of active agricultural land potentially subject to conservation is reduced by 9,663 acres. Because this Alternative will not conserve any additional land and Existing Agricultural Operations would continue to be a Covered Activity under this Alternative, no significant impacts to agricultural resources would result from implementation of this Alternative.

No Project Alternative. Under this Alternative, the land use changes and policies set forth in the proposed MSHCP would not be implemented. Development permitted under General Plans of the County and the Cities may result in the future Take of listed species and regulated habitats. As is currently the case, activities involving Take of State and/or federally listed species would require individual permitting on a project-by-project basis. Under this alternative, existing reserves would be retained with existing management strategies. Because the existing reserves would be retained in their current configuration, this Alternative results in no impacts to Existing Agricultural Operations.

Impacts to Lands Zoned or General Plan Designated Existing Zoning for Agricultural Use & or Subject to Williamson Act Contracts. Based on the thresholds identified above, impacts would be significant if the implementation of the proposed MSHCP or any of the alternatives would conflict with: (1) agricultural zoning or General Plan land use designations within the MSHCP Plan Area, or (2) a Williamson Act contract.

Proposed MSHCP. The proposed MSHCP will result in the conservation of approximately 347,000 acres on of existing public/quasi-public lands , and development application of criteria to assure additional conservation on private lands of approximately 153,000 acres (the Additional Reserve Lands). Lands defined as "public/quasi-public" include lands: (1) known to be in public ownership or managed for conservation and/or open space value, (2) or land contained in an existing reserve. Within the boundaries of existing reserves are 7,235 acres of active agricultural land , and 285 acres of land that is zoned or designated for agricultural use under a General Plan (Table 4). While the proposed MSHCP will encompass conservation on both public and private lands, the discussion that follows addresses only the potential impacts that may result from establishment of conservation areas on private lands that are currently not conserved because the Plan The proposed MSHCP will not change the allowable uses or otherwise affect the approximately 347,000 acres of existing reserves that are already in place. These activities will be permitted to continue as regulated by USFS, the Bureau of Land Management (BLM), and the other agencies which have administration over these public/quasi-public lands. Likewise, the MSHCP will have no effect on land outside of the Criteria Area which is zoned or General Plan designated for agricultural use. Potential impacts to lands zoned or General Plan designated for agricultural use or subject to Williamson Act contracts are therefore limited to the acreage within the Criteria Area, but outside of existing reserves, which may be conserved as Additional Reserve Lands.

About 161,792 acres of land within the MSHCP Plan Area are currently utilized for agricultural production. Using the Cities' existing and the County's proposed General Plan land use designations, of the 38,280 38,233 acres within the MSHCP Plan Area that are zoned or have a General Plan designation for agricultural use, it is anticipated that approximately 5,584 acres (about 14%) would may be included in the reserve areas, including 285 acres in existing reserves. Thus, up to 5,299 acres of land zoned or designated under the Cities' existing and the County's Draft General Plans may be included in the Additional Reserve Lands.

Under the Cities' and County's existing General Plan land use designations, of the 84,364 acres within the MSHCP Plan Area that are zoned or have a General Plan designation for agricultural use, up to 8,926 acres may be located within the Conservation Area, including 3,370 acres in existing reserves. Thus, up to 5,556 acres of land zoned or General Plan designated for agriculture under the current General Plans may be included in the Additional Reserve Lands.

It is not possible to determine how much of this acreage the 38,233 acres is subject to a Williamson Act contract because Williamson Act contracts are parcel-specific and, due to the criteria-based nature of the Plan, it is not possible to predict precisely which parcels will be included in the reserves. Thus, the MSHCP has the potential to conflict with existing agricultural designations for land included within the Conservation Area. However, the Proposed MSHCP is not a land use document and does not change zoning or land use designations. Under the MSHCP, Existing Agricultural Operations are a Covered Activity and would be allowed both within the Criteria Area and in the Plan Area outside of the reserves. Regardless of whether the potential impacts to agricultural resources are analyzed using the County's existing or proposed General Plan land use designations, Existing Agricultural Operations on land designated for agricultural uses will be permitted to continue. Therefore, under either the existing or proposed General Plan, implementation of the MSHCP will not result in the conversion of active farmland to non-agricultural uses. Thus, to the extent the 5,584 acres zoned or designated for agricultural use are being used for Existing Agricultural Operations, the MSHCP allows these uses to continue and the Existing Agricultural Operations will not be required to be assembled into the reserve if existing agricultural operations are occurring on those lands. Moreover, to the extent that General Plan designated or zoned land is not actively utilized for Existing Agricultural Operations, the MSHCP allows for the conversion of 10,000 acres of natural lands to agricultural uses within the Criteria Area and unlimited conversion to agricultural uses outside of the Criteria Area. Plus, the remaining 32,696 acres (about 86%) lands designated for agricultural use would benefit from the Plan , as because, to the extent these lands include Existing Agricultural Operations, their ongoing agricultural activities would receive Take coverage. Parcels subject to Williamson Act contracts qualify as Existing Agricultural Operations; the MSHCP specifically allows these agricultural activities to continue indefinitely. On balance, then Consequently, the MSHCP will not conflict with any existing agricultural zoning or General Plan designations or Williamson Act contracts and ; therefore, will not have significant agricultural impacts.

Table 4U identifies the amount of currently zoned or General Plan designated agricultural land in each city and the unincorporated areas of the County which will could fall within the limits of the Conservation Area and thus might be included in the reserves assembled under the MSHCP.

Listed, Proposed, and Strong Candidate Species Alternative. This alternative was developed to depict a potential conservation scenario that would address listed, proposed, and strong candidate species. A total of 32 listed and proposed species occurs in the proposed MSHCP Plan Area. In addition to the listed and proposed species, this alternative also considers the conservation needs of seven species identified as "strong candidates" for listing. Implementation of the Listed, Proposed, and Strong Candidate Species Alternative would conserve a total of 465,830 acres, including 346,530 acres within existing reserves and 119,300 acres of private land outside of existing reserves. Under the Cities' existing and the County's proposed General Plans, the Listed, Proposed, and Strong Candidate Species Alternative , it is anticipated that the reserve would may include about 2,724 3,009 acres (7%) of land that is zoned or designated under a General Plan for agricultural uses, including 285 acres within existing reserves. As with the MSHCP, the Listed, Proposed and Strong Candidate Species Alternative would include Existing Agricultural Operations as a Covered Activity , and agricultural operations which would be allowed to continue, even within the Criteria Area as well as in the Plan Area outside of the reserves. Thus, assuming the County's General Plan Update is adopted, 2,724 acres of zoned or General Plan designated agricultural land may be included in the Additional Reserve Lands under this alternative.

Under the Listed, Proposed, and Strong Candidate Species Alternative, it is anticipated that the Conservation Area may include approximately 7,544 acres of land that is zoned or designated under the Cities' and the County's existing General Plans for agricultural uses, including 3,370 acres within existing reserves. Thus, up to 4,174 acres of land currently General Plan designated or zoned for agricultural use might be conserved as part of the Additional Reserve Lands. As compared to the Proposed Action, this Alternative reduces the amount of land potentially subject to inclusion in the Additional Reserve Lands by 2,575 acres (assuming the County's General Plan Update is adopted) or 1,382 acres (calculated using the Cities' and the County's existing zoning and General Plan land use designations). (Table 4U)

As with the proposed MSHCP, the Listed, Proposed and Strong Candidate Species Alternative is not a land use policy and would not change zoning or land use designations. As with the MSHCP, the Listed, Proposed, and Strong Candidate Species Alternative would include Existing Agricultural Operations as a Covered Activity, which would be allowed to continue throughout the MSHCP Plan Area, including within the Criteria Area. To the extent that General Plan designated or zoned land is not actively utilized for Existing Agricultural Operations, this Alternative also allows for the conversion of natural lands to agricultural uses. The "Take Authorization" may apply to up to 10,000 acres of New Agricultural Land within the Criteria Area and unlimited Take Authorization is provided for the conversion of natural lands to agricultural uses outside of the Criteria Area.

The remaining 35,556 acres (about 93%) not located within the Criteria Area would further benefit from implementation of this Alternative, as their ongoing Existing Agricultural activities Operations would receive Take Coverage. As with the MSHCP, it is not possible to determine the extent of potential impacts to how much agriculturally zoned or designated acreage is subject to a Williamson Act contract due to the parcel-specific nature of Williamson Act contracts and the criteria-based nature of the Plan.

Tables 4T and 4U identify ies the amount of zoned or General Plan designated agricultural land with the Cities and the unincorporated areas of the County that would may be included in the reserve areas.

When compared to the proposed MSHCP, implementation of this alternative will reduce the potential conflict with land zoned or otherwise designated for agricultural use that is removed from agriculture to assemble the reserve by 2,860 acres (about 49%). Impacts to agriculturally zoned or designated land under this alternative remain less than significant because, like the MSHCP, this alternative allows all Existing Agricultural Operations to continue indefinitely, regardless of their location within the MSHCP Plan Area. Therefore, this alternative will not conflict with existing agricultural zoning, General Plan designations or Williamson Act contracts and will not have significant impacts to agricultural resources.

Listed and Proposed Species Alternative. This alternative was developed to depict a potential conservation scenario that would address only the 32 species listed or proposed for listing that are found within the MSHCP Plan Area. This alternative focuses largely on the conservation of the 32 listed and proposed species within the proposed MSHCP Plan Area, with less consideration of the broad-based NCCP biological concepts. Under this alternative, a total of 439,140 acres would be conserved, including 346,530 acres within existing reserves and 92,610 acres of currently private lands outside existing reserves. This alternative, including a list of covered species, is discussed in further detail in Section 2.4.

Under Cities' existing and the County's proposed General Plans, this alternative , may include approximately 2,445 2,730 acres (6%) of land currently zoned or designated under a General Plan for agricultural use would fall within the Conservation Area, including 285 acres within existing reserves. Thus, 2,445 acres of land zoned or designated under the Cities' existing and the County's Draft General Plans may be included in the Additional Reserve Lands under this alternative.

Under the Listed and Proposed Candidate Species Alternative, it is anticipated that the Conservation Area may include approximately 7,475 acres of land that is zoned or designated under the Cities' and the County's existing General Plans for agricultural uses, including 3,370 acres within existing reserves. Thus, 4,105 acres of currently designated or zoned land may be conserved as part of the Additional Reserve Lands under this alternative. As compared to the Proposed Action, this alternative reduces the amount of land within the Additional Reserve Lands that is currently zoned or designated under a General Plan for agricultural use by 2,854 acres (assuming the County's Draft General Plan is adopted) or 1,451 acres (calculated using the Cities' and the County's existing zoning and General Plan land use designations).

However, as indicated above and as with the proposed MSHCP, this alternative would include Existing Agricultural Operations as a Covered Activity , and agricultural operations which would be allowed to continue in the Criteria Area as well as in throughout the MSHCP Plan Area, including within the Criteria Area outside of the reserves. To the extent that land zoned or General Plan designated for agricultural use is not actively utilized for Existing Agricultural Operations, this alternative also allows for the conversion of natural lands to agricultural uses. The "Take Authorization" may apply to up to 10,000 acres of New Agricultural Land within the Criteria Area and unlimited Take Authorization is provided for the conversion of natural lands to agricultural uses outside of the Criteria Area. Agricultural lands outside the Criteria Area would further benefit from implementation of this alternative, as their ongoing Existing Agricultural activities Operations would receive Take Coverage. As with the MSHCP, it is not possible to determine the extent of potential impacts to how much agriculturally zoned or designated acreage is subject to a Williamson Act contract due to the parcel-specific nature of Williamson Act contracts and the criteria-based nature of the Plan. Tables 4T and 4U 4W identifies the amount of land within unincorporated areas and cities that would fall within the conservation area under this alternative.

As compared to the MSHCP, this alternative reduces the potential conflict with agriculturally zoned or General Plan designated land that would be removed from agriculture to assemble the reserve by 3,139 acres (54%). Impacts to agriculturally zoned or designated land under this alternative remain less than significant because, like the MSHCP, this alternative allows all Existing Agricultural Operations to continue indefinitely, regardless of their location within the MSHCP Plan Area. Therefore, this alternative will not conflict with existing agricultural zoning, General Plan designations or Williamson Act contracts and will not have significant impacts to agricultural resources.

Existing Reserves Alternative. Information regarding the size, character, and mission of the existing reserves is included in the MSHCP Description of Existing Reserves document (April 2000). Under this alternative, it is assumed that an MSHCP would be developed and associated take permits issued based on the existing reserves, but no additional conservation or management would occur within the existing reserves beyond that currently occurring or what might occur in the future with implementation of the U.S. Forest Service (USFS) Southern California Conservation Strategy. This alternative is described in further detail in Section 2.5.

Under the Existing Reserves Alternative, the land use status quo would not change in that no additional land would be conserved. Currently, the existing reserves include 7,235 acres (4%) of Existing Agricultural land Operations and 285 acres (0.8%) of land within western Riverside County that is zoned or designated for agricultural use under the Cities' existing or the County's Draft a General Plans. Under the Cities' and the County's current General Plans, 3,370 acres of land within the MSHCP Plan Area is zoned or General Plan designated for agricultural uses. Table 4U identifies the amount of currently zoned or General Plan designated land within unincorporated areas and cities the MSHCP Plan Area that lies within existing reserves.

While the MSHCP includes the establishment of conservation areas on private lands that are currently not conserved and the incorporation of existing reserves, this alternative does not. This alternative contemplates conservation in includes only those areas on which reserves are already established. Because the Alternative would not conserve any additional land, it would not change the existing environmental setting and would not create any conflict with any agricultural zoning, General Plan agricultural land use designation, or Williamson Act contract.

No Project Alternative. Under the No Project Alternative, subregional permits pursuant to the following State and federal regulations would not be issued: 1) Section 10(a)(1)(B) under the FESA; 2) Section 2081 under the CESA; and 3) Section 2835 of the NCCP Act (CFGC). Activities involving take of State and/or federally listed species would require individual permitting on a project-by-project basis, as is currently the case. This alternative is addressed in further detail in Section 2.6.

Under this alternative, the land use changes and policies that are being contemplated to implement the proposed MSHCP would not occur. However, the planning efforts currently being conducted under the RCIP for the County's General Plan and Countywide circulation element could still be adopted. Implementation of the various elements of those plans may result in the take of listed species and regulated habitats. Activities involving take of State and/or federally listed species would require individual permitting on a project-by-project basis, as is currently the case. Under this alternative, existing reserves would be retained with existing management strategies. Because the existing reserves would be retained in their current configuration, and no additional lands would be conserved, the no impacts would result from implementation of this alternative, as explained above in the discussion of would be the same as the Existing Reserves Alternative , as summarized in Table 4X.

Analysis of Significance.

Because Existing Agricultural Operations will be permitted to continue within the Criteria Area (subject to provisions outlined in the proposed MSHCP), and an additional 10,000 acres of non-agricultural land may be converted to agricultural land and receive Take Authorization, implementation of the proposed MSHCP, and the Listed, Proposed and Strong Candidate Alternative and the Listed and Proposed Candidate Alternative each of the alternatives will not significantly conflict with zoning or designation of lands for agricultural use or any Williamson Act contract or result in the conversion of Existing Agricultural Operations to non-agricultural uses. Since no additional land will be conserved under the Existing Reserves Alternative and the No Project Alternative, these Alternatives likewise will not conflict with zoning or designation of lands for agricultural use or any Williamson Act contract; therefore, these alternatives will not have a significant effect on Existing Agricultural Operations.

Mitigation. No significant impact would occur. Therefore, no mitigation is required.

Significance of Impacts after Mitigation. No significant impacts would occur due to conflict with agricultural zoning, land use designations, or Williamson Act contracts would occur under the Proposed Action or any of the MSHCP alternatives.

Impacts to Designated Farmland. Impacts would be significant if the implementation of the Proposed Action or an alternative would result, directly or indirectly, in the conversion of Designated Farmland to non-agricultural uses. The specific discussions and tables charts included above detail the amount of Designated Farmland that would may be incorporated within the Conservation Area(s) created under the proposed MSHCP and the various alternatives. (See Table 4R.) As stated earlier in this section, the designation of land by the State as Prime, Unique, or Statewide Important Farmland does not necessarily imply that the land is currently utilized for active agricultural production. The proposed MSHCP will not impose new or additional restrictions on agricultural operations adjacent to the MSHCP Conservation Area Reserve nor will it attempt to displace Existing Agricultural Operations that the property owners wish to continue.

Under the Proposed Action, 3,848 up to an estimated 10,419 acres of Designated Farmland may be located within the Conservation Area; this figure includes the acreage included in both the Additional Reserve Lands and the existing reserves. in the MSHCP Plan Area will be added to the conservation area (above the amount of Designated Farmland already included in the existing reserves). Under the alternatives to the proposed MSHCP, the amount of Designated Farmland that is potentially subject to inclusion in the Additional Reserve Lands and thus might be added to the Conservation Area ranges from 3,935 to 6,563 3,869 to 3,935 acres.

Agricultural activities (on parcels included in the Existing Agricultural Operations Database that do not require a County discretionary permit, or other discretionary authorization, or certain City ministerial permits) will receive Incidental Take Authorization and will not be required to implement MSHCP mitigation requirements. After the effective date of the proposed MSHCP, if Section 7.0 of the MSHCP is implemented, the Take Authorization may be applied to a limited number of new lands to be used for new agricultural operations. The take authorization may be applied to up to 10,000 acres of New Agricultural Lands within the Criteria Area during the term of the proposed MSHCP. The Take Authorization may be applied to new Agricultural Lands as allowed to increase pursuant to applicable provisions of the proposed MSHCP, upon:

Submission and approval of an Agricultural Grading/Clearing Exception Form as set forth in Riverside County Ordinance No. 457; and either
Execution of a Williamson Act contract covering the new agricultural land; or
County approval of any other mechanism providing equal or better assurance that the proposed new agricultural lands will be used for agricultural production.

In all instances, issuance of a Certificate of Inclusion (or other mechanism acknowledging Take Authorization) will occur prior to Incidental Take Authorization. The County will process all Agricultural Grading/Clearing Exception Forms pursuant to the requirements of Riverside County Ordinance No. 457.

Proposed MSHCP. Approximately 99,090 acres of land within the MSHCP Plan Area qualify as Designated Farmland. It is important to note that these designations are based on soils mapping prepared by the Farmland Mapping and Monitoring Program rather than existing or authorized land use. Therefore, it is possible for the amount of acreage included in Designated Farmland to exceed the amount of acreage currently utilized for agricultural production. Under the MSHCP, up to 10,419 acres of Designated Farmland may be located within the Conservation Area. Of this, 6,563 acres are located in existing reserves. To the extent that Designated Farmland within the Criteria Area is not being used for current Existing Agricultural Operations, it could be assembled into the reserve, or it may become a Covered Activity if new Agricultural Operations are commenced onsite. The amount of Designated Farmland that could be conserved as Additional Reserve Lands under the MSHCP if they are not being used for Existing Agricultural Operations is approximately 3,848 3,856 acres or 4 percent of existing Designated Farmland within the MSHCP Plan Area. Because the proposed MSHCP exempts Existing Agricultural Operations and provides a mechanism for the conversion of up to 10,000 acres of non-agricultural land within the conservation Criteria Area to agricultural use, potential impacts related to conversion of Designated Farmland would be offset and, overall, less than significant. However, if Section 7.3.3 of the MSHCP is not implemented, the offset will not occur. In this event, impacts related to conversion of Designated Farmland will may be significant.

Listed, Proposed, and Strong Candidate Species Alternative. Under the Listed, Proposed, and Strong Candidate Species Alternative, to the extent that Designated Farmland within the Criteria Area is not being used for current Existing Agricultural Operations, it could be assembled into the reserve. This would may result in up to 10,498 acres 3,935 acres (4%) of the Designated Farmland being added to located within the Conservation Area under this alternative. Table 4R identifies the amount of Designated Farmland within the Cities and unincorporated areas that will may fall within the Conservation Area. When compared to the Proposed MSHCP, this alternative reduces increases the amount of Designated Farmland added to within the Conservation Area by 79 acres.

Listed and Proposed Species Alternative. Under the Listed and Proposed Species Alternative, to the extent that Designated Farmland within the Criteria Area is not being used for current Existing Agricultural Operations, it could be assembled into the reserve. This would may lead to 4,881 10,432 acres (5%) of the Designated Farmland within the proposed MSHCP Plan Area being added to the Conservation Area. Table 4R identifies the amount of Designated Farmland within the Cities and unincorporated areas that would may fall within the Conservation Area under this alternative. When compared to the proposed MSHCP, the amount of Designated Farmland within the Conservation Area would may be reduced increased by 13 acres under this alternative.

Existing Reserves Alternative. Under the Existing Reserves Alternative, the amount of Designated Farmland (6,563 acres) included within existing reserves will not change. When compared to the proposed MSHCP, the amount of Designated Farmland within the Conservation Area would may be reduced. This alternative will not have any significant impact related to the conversion of Designated Farmland, since no additional land will be conserved. Compared to the Proposed Action, the amount of Designated Farmland potentially subject to inclusion within the Conservation Area may be decreased by 3,856 acres under this alternative.

No Project Alternative. Under this alternative, the land use changes and policies being contemplated to implement the proposed MSHCP would not occur. However, planning currently being conducted under the RCIP for the County's General Plan and Countywide circulation element could still be adopted. Implementation of the various elements of those plans may result in the Take of listed species and regulated habitats. Activities involving Take of State and/or federally listed species would require individual permitting on a project-by-project basis, as is currently the case. Under this alternative, existing reserves would be retained with existing management strategies. Because the existing reserves would be retained in their current configuration, no additional land would be conserved and the amount of Designated Farmland that will may fall within the Conservation Area under this alternative would be the same as that for the Existing Reserves Alternatives (as further identified in Table 4X). This alternative will not have any significant impact related to the conversion of Designated Farmland, since no additional land will be conserved. Compared to the Proposed Action, the amount of Designated Farmland potentially subject to inclusion within the Conservation Area may be decreased by 3,856 acres under this alternative.

Analysis of Significance. Up to 10,419 6,563 acres of Designated Farmland may be will be added to the reserve located within the Conservation Area under the proposed MSHCP. Between 6,563 acres and 10,498 acres may be included in the Conservation Area under and the alternatives. However, because Existing Agricultural Operations on Designated Farmland will be permitted to continue throughout the MSHCP Plan Area, including within the Criteria Area (subject to provisions outlined in the proposed MSHCP), and Designated Farmland not actively utilized for agricultural operations may obtain Take Coverage if it is converted to agricultural use, implementation of the proposed MSHCP; the Listed, Proposed and Strong Candidate Species Alternative; and the Listed and Proposed Species Alternative will not result in the conversion of Designated Farmland to non-agricultural use. Since no Designated Farmland will be conserved under the Existing Reserves Alternative and the No Project Alternative, these Alternatives will not have a significant effect. Assuming that Section 7.3.3 of the MSHCP is implemented, the potential impact associated with this issue is less than significant under the MSHCP and each of the alternatives. Therefore, no mitigation is required. However, if Section 7.3.3 of the MSHCP is not implemented, the offset will may not occur and impacts related to conversion of Designated Farmland will be significant under the MSHCP (Proposed Project); the Listed, Proposed and Strong Candidate Species Alternative; and the Listed and Proposed Species Alternative.

Mitigation. Assuming that Section 7.3.3 of the MSHCP is implemented, the potential impact associated with this issue is less than significant. Therefore, no mitigation is required. However, if Section 7.3.3 of the MSHCP is not implemented, the offset will not occur and impacts related to conversion of Designated Farmland will be significant under the MSHCP (Proposed Project) Project; the Listed, Proposed and Strong Candidate Species Alternative; and the Listed and Proposed Species Alternative. There is no feasible means of mitigating for this potentially significant impact under these three alternatives.

Significance of Impacts after Mitigation. Assuming that Section 7.3.3 of the MSHCP is implemented, impacts related to conversion of Designated Farmland would be less than significant for implementation of the proposed MSHCP and each of the proposed MSHCP alternatives. However, if Section 7.3.3 of the MSHCP is not implemented, the allowance of up to 10,000 acres of New Agricultural Lands within the Criteria Area the offset will not occur and impacts related to conversion of Designated Farmland will be significant and unavoidable under the MSHCP (Proposed Project) Project; the Listed, Proposed and Strong Candidate Species Alternative; and the Listed and Proposed Species Alternative.

4.2.2 Mineral Resources

Mineral extraction is an important component of Riverside County's economy. The County has extensive deposits of clay, limestone, iron, sand, and aggregates. Mineral deposits in the County are important to many industries, including construction, transportation, and chemical processing. The value of mineral deposits within the County is enhanced by their close proximity to urban areas. The proposed MSHCP Plan Area includes an area of approximately 1.26 million acres (1,966 square miles) and encompasses unincorporated portions of western Riverside County and 14 incorporated cities (Banning, Beaumont, Calimesa, Canyon Lake, Corona, Hemet, Lake Elsinore, Moreno Valley, Murrieta, Norco, Perris, Riverside, San Jacinto, and Temecula). Portions of land designated for conservation in cities and in unincorporated areas of the County may contain mineral resources. Implementation of the proposed MSHCP could prohibit or limit the future extraction potential of these resources.

Currently, the majority of mineral resource extraction within western Riverside County takes place in unincorporated County areas (3,100 acres). Resource extraction in incorporated cities within the Plan Area ranges from 2 to approximately 500 acres, with the majority of extraction occurring in Corona and Lake Elsinore. The Riverside County General Plan has set aside approximately 5,200 areas (an increase of 68%) for future mineral extraction use. Projections for incorporated cities are not available, but it is assumed that this increase is representative of the region.

Classification of land within California takes place according to a priority list that was established by the State Mining and Geology Board (SMGB) in 1982, or when the SMGB is petitioned to classify a specific area. The SMGB has also established Mineral Resources Zones (MRZ) to designate lands that contain mineral deposits.

Mineral Resource Zone 2

Based on the assessment of mineral resources prepared by the California State Department of Mines and Geology, significant aggregate mineral resources exist within Riverside County. Land designated as Mineral Resource Zone 2 (MRZ-2) represents areas containing significant mineral deposits, which may be suitable for mineral extraction. MRZ-2 is defined as an area where adequate information indicates that significant mineral deposits are present, or where it is judged that a high likelihood for their presence exists.

As discussed in Section 3.2.2, approximately 22 percent of land that is designated MRZ2 is currently used for mineral extraction within the Plan Area. Also, as discussed, many areas designated MRZ-2 are also highly suited for uses other than mineral resource extraction (such as urban/residential development and natural open space). It is highly unlikely that all MRZ-2 areas within the region would ultimately be used for mineral extraction. Furthermore, mineral resource extraction often requires extensive environmental mitigation to compensate for the harmful impacts to biological resources present in or near mining operations. The proposed MSHCP would facilitate the permitting process for mineral extraction with respect to biological resources, as it would for other development throughout the Plan Area. The MRZ-2 designation does not specify the quality or quantity of mineral deposits, which may make the use of these areas for impact quantification potentially misleading. However, as the MRZ classifications represent the best available data for mineral resources (aside from current extraction data, which was provided in Section 3.2.2), the mineral resource impact analysis focuses on impacts to MRZ-2 areas.

Impacts

The proposed MSHCP and alternatives would attain most of the basic objectives of the project with varying environmental effects. Table 4 YV identifies approximate acreage of MRZ-2 that currently exists and that would be set aside for conservation under the proposed MSHCP and alternatives.

Thresholds of Significance/Criteria for Determining Significance

The Proposed Action or alternatives would have a significant impact on mineral resources if they:

Resulted in the loss of availability of a known mineral resource that would be of value to the region and the residents of the State;
Resulted in the loss of an availability of a locally important mineral resource recovery site delineated on a local general plan, specific plan, or other land use plan; or
Directly conflicted or resulted in land use incompatibility with adjacent existing and planned land uses or with the environmental goals of the general plans and community plans of the jurisdictions participating in the proposed MSHCP.

Loss of Regionally Valuable Resource

Proposed MSHCP. Implementation of the proposed MSHCP would result in 4,300 acres of land with known potential to be used for mineral extraction being set aside for conservation. This represents approximately 22 percent of such lands within the proposed Plan Area. Areas set aside for conservation would not be available for mineral extraction use; however, no areas currently used for mineral extraction would be set aside. As 10,900 acres (2.5 times the number of acres currently used in mineral resource extraction) of MRZ-2 lands would remain available for use, the proposed MSHCP would not result in a significant loss of a regionally valuable resource.

Table 4 YV - Mineral Resource Zone 2 Acres under the Proposed MSHCPand Action Alternatives¹

Notes: 1 Cities not listed above (Beaumont, Calimesa, Canyon Lake, Hemet, Moreno Valley, Murrieta, Norco, Perris, San Jacinto, and Temecula) do not contain areas designated as Mineral Resources Zone 2 (MRZ-2) within the city limits. The Existing Reserves Alternative would not result in restrictions to land use beyond those already existing within reserve areas. 2 Numbers are a percentage of the total 19,500 acres of MRZ-2 existing within the proposed MSHCP Plan Area. 3 Numbers are a percentage of the total existing MRZ-2 acres within individual cities/western Riverside County under the indicated Alternative

Listed, Proposed, and Candidate Species Alternative. Implementation of this alternative would result in 3,900 acres of land with known potential to be used for mineral extraction being set aside for conservation. This represents approximately 17 percent of such lands within the Plan Area. Areas set aside for conservation would not be available for mineral extraction use; however, no areas currently used for mineral extraction would be set aside. As 11,300 acres (2.6 times the number of acres currently used in mineral resource extraction) of MRZ-2 lands would remain available for use, this alternative would not result in a significant loss of a regionally valuable resource.

Listed and Proposed Species Alternative. Implementation of this alternative would result in 3,300 acres of land with known potential to be used for mineral extraction being set aside for conservation. This represents approximately 20 percent of such lands within the Plan Area. Areas set aside for conservation would not be available for mineral extraction use; however, no areas currently used for mineral extraction would be set aside. As 11,300 acres (2.6 times the number of acres currently used in mineral resource extraction) of MRZ-2 lands would remain available for use, this alternative would not result in a significant loss of a regionally valuable resource.

Existing Reserves Alternative. Implementation of this alternative would not represent a change over existing conditions for mineral resource extraction. No currently available MRZ-2 zones would be set aside for conservation, except where required for project mitigation under current Wildlife Agency regulations. No significant impacts would occur.

No Project Alternative. Implementation of this alternative would not represent a change over existing conditions for mineral resource extraction. No currently available MRZ-2 zones would be set aside for conservation, except where required for project mitigation under current Wildlife Agency regulations. No significant impacts would occur.

Loss of Locally Important Resource

Proposed MSHCP. Mineral resource extraction throughout the Plan Area presently occurs on approximately 22 percent of available land. The existing extraction sites are locally important resources, and would not be affected under the proposed MSHCP. The sites currently in use would not be restricted in any way. The potential for establishment of additional mineral extraction sites in the future would, however, be restricted in some areas. By applying the estimated growth rate of 68 percent (from the Riverside County General Plan build out land use designations) to each area, and comparing the acres needed for growth to the acres of MRZ-2 available after project implementation, potential impacts to local resources were determined (for cities with land classified as MRZ-2). These impacts are summarized in Table 4 ZW. As indicated in Table 4 ZW, there would be sufficient available acres of MRZ-2 land to accommodate anticipated future growth in mineral extraction.

Table 4ZW - Land Available to Accommodate Anticipated Mineral Extraction Growth
Location	Anticipated Growth (68 percent of Existing)	Acres Remaining for Growth after Proposed Action/Impact	Acres Remaining for Growth after Listed, Proposed, and Strong Candidate Species Alternative/Impact	Acres Remaining for Growth after Listed and Proposed Species Alternative/Impact
Unincorporated Western Riverside County	2,100	9,500 / no	10,300 / no	10,900 / no
Banning	120	1,400 / no	1,300 / no	1,300 / no

Riverside	10	1,700 / no	1,700 / no	1,700 / no

Listed, Proposed, and Candidate Species Alternative. Mineral resource extraction throughout the Plan Area presently occurs on approximately 22 percent of available land. The existing extraction sites are locally important resources, and would not be affected under this alternative. The sites currently in use would not be restricted in any way. The potential for establishment of additional mineral extraction sites in the future would, however, be restricted in some areas. As indicated in Table 4 ZW, there would be sufficient available acres of MRZ-2 land to accommodate anticipated future growth in mineral extraction throughout the Plan Area, with the exception of the City of Lake Elsinore. Mineral extraction growth within Lake Elsinore would be restricted to 55 percent.

Listed and Proposed Species Alternative. Mineral resource extraction throughout the Plan Area presently occurs on approximately 22 percent of available land. The existing extraction sites are locally important resources, and would not be affected under this alternative. The sites currently in use would not be restricted in any way. The potential for establishment of additional mineral extraction sites in the future would, however, be restricted in some areas. As indicated in Table 4 ZW, there would be sufficient available acres of MRZ-2 land to accommodate anticipated future growth in mineral extraction throughout the Plan Area, with the exception of the City of Lake Elsinore. Mineral extraction growth within Lake Elsinore would be restricted to 55 percent.

Existing Reserves Alternative. Implementation of this alternative would not change the existing land uses or planned land uses throughout the Plan Area. Thus, no locally important resources would be adversely affected. No significant impacts would occur.

No Project Alternative. Implementation of this alternative would not change the existing land uses or planned land uses throughout the Plan Area. Thus, no locally important resources would be adversely affected. No significant impacts would occur.

Conflicts and Land-Use Incompatibilities

Proposed MSHCP. Implementation of the proposed MSHCP would not result in development or mineral extraction. Thus, no land-use incompatibilities would occur. The proposed MSHCP would accommodate growth and development as well as natural resource conservation throughout the Plan Area, and would further the goals of the general plans and community plans of the jurisdictions participating in the proposed MSHCP. Thus, no significant impacts would occur.

Listed, Proposed, and Candidate Species Alternative. Implementation of this alternative would not result in development or mineral extraction. Thus, no land-use incompatibilities would occur. This alternative would accommodate growth and development as well as natural resource conservation throughout the Plan Area, and would further the goals of the general plans and community plans of the jurisdictions participating in the proposed MSHCP. Thus, no significant impacts would occur.

Listed and Proposed Species Alternative. Implementation of this alternative would not result in development or mineral extraction. Thus, no land-use incompatibilities would occur. This alternative would accommodate growth and development as well as natural resource conservation throughout the Plan Area, and would further the goals of the general plans and community plans of the jurisdictions participating in the proposed MSHCP. Thus, no significant impacts would occur.

Existing Reserves Alternative. This alternative would not change the existing land uses or have any effect on the planned land uses throughout the Plan Area. Thus, it would not result in any change to the environmental or planning goals of the jurisdictions within western Riverside County. The potential beneficial effects of the proposed MSHCP (facilitating growth and development, including potential mineral extraction) would also not occur with this alternative.

No Project Alternative. This alternative would not change the existing land uses or have any effect on the planned land uses throughout the Plan Area. Thus, it would not result in any change to the environmental or planning goals of the jurisdictions within western Riverside County. The potential beneficial effects of the proposed MSHCP (facilitating growth and development, including potential mineral extraction) would also not occur with this alternative.

Analysis of Significance

Impacts to regionally valuable resources would be less than significant for the Proposed Action and all alternatives. Likewise, impacts pertaining to conflicts and land-use incompatibilities would be less than significant for all. Impacts pertaining to a loss of a locally important resources would be less than significant for the proposed MSHCP and the Existing Reserves/No Project Alternative. With the Listed, Proposed, and Strong Candidate Species Alternative and the Listed and Proposed Species Alternative, impacts to locally important resources would be restricted to the City of Lake Elsinore, where potential growth of mineral extraction areas would be restricted to 55 percent, which is less than the anticipated regional growth rate of 68 percent. This impact would be significant and unavoidable.

Mitigation Measures

As no significant impacts would occur for the proposed MSHCP and the Existing Reserves/No Project Alternative, no mitigation measures are required. The Listed, Proposed, and Strong Candidate Species Alternative and the Listed and Proposed Species Alternative would result in a significant unavoidable impact to the City of Lake Elsinore, as conserved lands would reduce the area available for expansion of mineral resource extraction to below the anticipated growth rate. No mitigation is available for this impact.

Level of Significance after Mitigation

No significant impacts would occur for the proposed MSHCP, the Existing Reserves Alternative, or the No Project Alternative. No regionally significant impacts would occur under the remaining alternatives, however, a significant unavoidable impact with respect to future mineral resource extraction expansion would occur in the City of Lake Elsinore with the Listed, Proposed, and Strong Candidate Species Alternative and with the Listed and Proposed Species Alternative.

4.3 Population, Housing, and Employment

4.3.1 Introduction

The following section analyzes the impacts resulting from implementation of the proposed MSHCP and alternatives and the requirement for the County and each City to provide adequate housing for its proportionate share of the population. Additionally, the impacts related to employment are also addressed.

Section 65581 of the California Government Code, requires cities and counties within each jurisdiction's Housing Element to identify adequate sites for housing and make adequate provisions for the existing and projected needs of all economic segments of the community.

The Housing Element's requirements to accommodate projected housing needs are a critical factor influencing the housing supply and availability statewide and within regional housing markets. The local regulation of the housing supply through planning and zoning powers affects the State's ability to achieve the State housing goal of “decent housing and a suitable living environment for every California family,” and is an important influence on housing costs.

The implementation of the proposed MSHCP will be consistent with and complement the implementation of the Riverside County General Plan and its Housing Element. Therefore, the population, housing, and employment policies and standards set forth in the General Plan and its Housing Element will be adhered to at all times during the MSHCP process.

One of the goals of the proposed MSHCP is to enhance and maintain biological diversity and ecosystem processes while accommodating projected future economic growth. Implementation of the proposed MSHCP would preserve quality of life by providing that growth will be well-managed and well-planned and will be integrated with an open-space system. This leads to a balance in land use planning of not only homes and jobs, but also habitat and open space. One of the goals of the proposed MSHCP is to improve the future economic development in the County by providing an efficient, streamlined regulatory process through which development can proceed in an efficient way. The proposed MSHCP and the General Plan will provide the County with a clearly articulated blueprint describing the general areas where future development should and should not occur. These goals are also included in the proposed Western Riverside County MSHCP Planning Agreement, which states that “the County and Cities concur with the goals of the NCCP Act and have determined that it may be the proper vehicle for the County and Cities to provide appropriate protection for the range of biological resources within its jurisdiction while at the same time safeguarding the economic, social, health, safety, and property rights of its residents and property owners.”

4.3.2 Criteria for Determining Significance

The following criteria were used to determine significance of impacts from the adoption or implementation of the proposed MSHCP or alternatives on population, housing, and employment in the MSHCP study area. Impacts shall be considered significant if the project would:

Directly or indirectly induce substantial growth;
Displace substantial numbers of residential units, requiring the construction of replacement housing elsewhere;
Displace a substantial number of persons, necessitating the construction of replacement housing; and/or
Exacerbate (make worse) the jobs-to-housing imbalance in western Riverside County and the cities within western Riverside County.

4.3.3 Impacts Analysis

Proposed MSHCP

The proposed MSHCP will be comprised of conservation on existing public/quasi-public lands and new conservation on approximately 153,000 acres of private lands within the Criteria Area. The precise configuration for new conservation within the Criteria Area has not been defined or mapped. The proposed MSHCP includes 120,200 acres within the County and 14,800 acres within the cities of western Riverside County that are currently designated for housing units. It also includes 3,200 acres in the County and 2,900 acres within the cities of western Riverside County that are currently designated for employment use.

Implementation of the MSHCP will likely cause dwelling units and employment facilities previously planned for development within the Criteria Area to be shifted into areas that are not to be conserved. However, implementation of the proposed MSHCP will not change (either reduce or increase) the amount of development (dwelling units and/or employment facilities) allowed pursuant to local land use controls. Regardless of whether the MSHCP is adopted, then, the same number of dwelling units and commercial/industrial/office space will be developed. Implementation of the MSHCP will simply change the location of development and possibly site-specific density (e.g., clustering) within western Riverside County. In other words, the only difference the MSHCP will make to future development is to change the precise location of the anticipated land uses within western Riverside County.

To address the challenge of a rapidly growing region and the need to adequately develop housing and employment opportunities for all economic segments of the community, the County and cities within western Riverside County will utilize multiple planning techniques. These methods include zoning overlays, general plan amendments, zoning ordinance amendments, the clustering of development, and density bonuses.

State law requires density bonuses in all jurisdictions. California Government Code Section 65915 requires that cities and counties provide development incentives, such as a density bonus, for projects providing the following affordable housing.

20 percent of the dwelling units for lower income households, as defined in Health and Safety Code Section 50079.5 (up to 80 percent of the area median income, adjusted for household size);
10 percent of the dwelling units for very low income households as defined in Health and Safety Code Section 50105 (up to 50 percent of the area median income, adjusted for household size); or
50 percent of the dwelling units for “qualifying residents” as defined in Section 51.3 of the Civil Code (senior citizens).

Utilizing density bonuses will not only help to ensure the jurisdictions' availability of housing units, but will also be an incentive for developers to construct dwelling units at a higher density.

The MSHCP does not authorize or contemplate any growth, construction or development. Rather, the Plan merely provides a means for managing and planning for anticipated regional growth in a manner that will be sensitive to the needs of regional biological resources. Thus, the MSHCP is more accurately characterized as providing a means of planning for the biological effects of projected growth, not as a project that facilitates growth. The MSHCP therefore will does not directly induce growth and will not have a significant direct impact on population, housing, and employment.

However, the MSHCP will remove existing impediments to growth because it will authorize take of listed species. Currently, the federal and state Endangered Species Acts require issuance of an incidental take permit prior to any action that would take species. Once the MSHCP is implemented, the regulatory process for development of land will be simplified because incidental take coverage will be granted in accordance with the terms of the Plan and the IA. Thus, the MSHCP will remove existing impediments to growth outside the Conservation Area but within the Plan Area. Because the MSHCP removes these existing impediments, it will indirectly induce growth. Although implementation of the MSHCP will not cause growth in western Riverside County to exceed regional growth projections, out of an abundance of caution, the Project's indirect growth-inducing impacts are deemed to be substantial and therefore significant. Therefore, the MSHCP will have significant indirect impacts on this subcategory of population, housing, and employment.

The MSHCP will not displace substantial numbers of housing units or persons; implementation will only restrict where future development could occur. Additionally, implementation of the MSHCP will not exacerbate the jobs to housing imbalance within western Riverside County and cities. Implementation of the proposed plan will have the same effect on employment facilities as housing units, which is merely to modify future locations and densities of development. Therefore, the adoption and/or implementation of the MSHCP will not have a significant impact on population, housing, and employment with regard to the second, third, or fourth thresholds of significance.

Listed, Proposed, and Strong Candidate Species Alternative

Under this alternative, a total of 465,860 acres would be conserved, including 346,530 acres within existing reserves and 119,330 acres of private land outside existing reserves. Of the 119,330 acres of private land within the Listed, Proposed, and Strong Candidate Species Alternative, there are 71,800 acres within the County and 13,400 acres within the cities of western Riverside County that are currently designated for housing units. This Alternative also includes conservation of 2,000 acres in the County and 2,400 acres within the cities of western Riverside County that are currently designated for employment use.

In regard to population, housing, and employment, the only difference between the proposed plan and the Listed, Proposed, and Strong Candidate Species Alternative is the amount of privately held land that would be included in the plan. The Listed, Proposed, and Strong Candidate Species Alternative will conserve 33,698 acres less of privately held land than the proposed MSHCP. Although the Listed, Proposed, and Strong Candidate Species Alternative will conserve far less species and acres of land, all of the other goals of this Alternative are exactly the same as the MSHCP.

The difference between implementing the proposed MSHCP and the Listed, Proposed, and Strong Candidate Species Alternative would be a reduction in the amount open space conserved, and, hence, in the amount of land uses shifted outside the conservation area. Within the unincorporated western Riverside County, the Alternative would conserve 48,400 acres less of land designated for housing units and 1,200 acres less of land designated for employment use than the MSHCP would. Implementation of this alternative would therefore cause less shifting in the location of development within western Riverside County. Within the currently incorporated cities of western Riverside County, the Alternative would conserve 1,400 acres less of land designated for housing and 500 acres less of land designated for employment use. Again, implementation of this alternative would reduce the shifting of land use locations in this acreage.

Like the MSHCP, the Listed, Proposed, and Strong Candidate Species Alternative would create a criteria-based reserve system. The only differences between the MSHCP and the Listed, Proposed, and Strong Candidate Species Alternative are the number of species and the amount of acreage conserved. As with the MSHCP, this Alternative is growth-accommodating, not growth-inducing. Therefore, it would not have significant direct impacts on population, housing, and employment in that it would not directly induce substantial population growth in the Plan Area. However, just like the MSHCP, the Listed, Proposed, and Strong Candidate Species Alternative would remove an impediment to growth in that it would provide authorization to take the species covered by the alternative plan. Thus, like the MSHCP, the Listed, Proposed and Strong Candidate Species Alternative could be characterized as having significant indirect impacts on population, housing, and employment because it could be deemed to indirectly induce substantial population growth in the Plan Area.

Like the MSHCP, the Listed, Proposed and Strong Candidate Species Alternative does not propose or authorize construction or development; the Alternative merely restricts the location of future development on undeveloped lands. Thus, implementation of the Alternative will not displace substantial numbers of housing units or persons. Additionally, implementation of the Listed, Proposed and Strong Candidate Species Alternative will not exacerbate the jobs-to-housing imbalance within western Riverside County and cities. Hence, adoption and implementation of the Listed, Proposed and Strong Candidate Species Alternative would have a less than significant impact on the second, third, and fourth thresholds of significance for population, housing and employment.

Listed and Proposed Candidate Species Alternative

Under the Listed and Proposed Candidate Species alternative, a total of 451,370 acres would be conserved, including 357,530 acres within existing reserves and 93,809 acres of private land outside existing reserves. Of the 93,840 acres of private land within the Listed and Proposed Candidate Species Alternative there are 52,800 acres within the County and 12,300 acres within the cities of western Riverside County that are currently designated for housing units. This Alternative would also conserve 2,000 acres in the County and 3,000 acres within the cities of western Riverside County that are currently designated for employment use.

In regard to population, housing, and employment, the only difference between the MSHCP and the Listed and Proposed Candidate Species Alternative is the amount of privately held land that would be included in the plan. The Listed and Proposed Candidate Species Alternative will conserve 65,530 acres less of privately held land than the MSHCP. Like the Listed, Proposed, and Strong Candidate Species Alternative, the Listed and Proposed Species Alternative will conserve fewer species and acres than the MSHCP, but all of the other goals of the Listed and Proposed Species Alternative are exactly the same as the MSHCP.

As compared to the MSHCP, the Listed and Proposed Species Alternative would reduce the amount of open space conserved, and, hence, reduce the amount of land uses that would be shifted outside the conservation area. Within the unincorporated western Riverside County 67,400 acres less of land designated for housing units and 1,200 acres less of land designated for employment use would be shifted. Within the cities of western Riverside County 2,500 acres less of land designated for housing would be shifted.

Like the MSHCP and the Listed, Proposed, and Strong Candidate Species Alternative, the Listed and Proposed Species Alternative would create a criteria-based reserve system. Again, the only differences between this Alternative and the MSHCP and the Listed, Proposed, and Strong Candidate Species Alternative are the number of species and the amount of acreage conserved. As with the MSHCP, the Listed and Proposed Species Alternative is growth-accommodating, not growth-inducing . Therefore, the Listed and Proposed Species Alternative would not have significant direct impacts on population, housing, and employment because it would not directly induce substantial population growth in the Plan Area.

However, just like the MSHCP and the Listed, Proposed, and Strong Candidate Species Alternative, the Listed and Proposed Species Alternative would remove an impediment to growth by providing take authorization for the species covered by the alternative plan, i.e., the 31 listed species and the one species proposed for listing that occur in within the Plan Area. Thus, like the MSHCP, the Listed and Proposed Species Alternative may be deemed to have significant indirect impacts on population, housing, and employment because it can be characterized as indirectly inducing substantial population growth in the Plan Area.

The Listed and Proposed Species Alternative will not displace substantial numbers of housing units or persons; as with the Plan and the Listed, Proposed and Strong Candidate Species Alternative, implementation of the Listed and Proposed Species Alternative will only restrict where future development could occur. Additionally, implementation of the Listed and Proposed Species Alternative will not exacerbate the jobs-to-housing imbalance within western Riverside County and cities. Hence, adoption and implementation of the Listed and Proposed Candidate Species Alternative would have a less than significant impact on the second, third, and fourth thresholds of significance for population, housing, and employment.

Existing Reserves and No Project Alternatives

With the Existing Reserve and No Project Alternatives, no land would be added to the existing conservation areas that total approximately 346,530 acres within western Riverside County. Future development within western Riverside County would be constructed as permitted by the County's and cities' General Plans, Housing Elements,

and Zoning Ordinances. Under these Alternatives, land use changes and policies that are being contemplated to implement the MSHCP would not occur. However, planning currently being conducted under the RCIP for the County's General Plan could still be adopted. Under the No Project Alternative, existing reserves would be retained with existing management strategies, whereas under the Existing Reserves Alternative, existing reserves would be retained and new management strategies would be implemented to increase the reserves' benefits to sensitive species and their habitat. Impacts resulting from development activities would continue to be subject to a variety of local, State, and federal regulatory processes. Implementation of either the Existing Reserves Alternative or the No Project/No Action Alternative would not change the current development pattern or development regulation processes within western Riverside County or its cities. The location and impacts of development would be analyzed on a case-by-case basis, as it is currently done. There would be no regulatory change to lands that are privately held. Moreover, implementation of either the Existing Reserves Alternative or the No Project/No Action Alternative would not include the authorization of any incidental take of listed species. Thus, in contrast to the MSHCP and the Alternatives discussed above, neither of these Alternatives removes any existing regulatory impediment to growth. Neither the Existing Reserves nor the No Project/No Action Alternative will induce substantial population growth, either directly or indirectly.

Moreover, neither of these Alternatives will cause the displacement of a substantial number of persons or residential units. Likewise, neither of these Alternatives will exacerbate the jobs-to-housing imbalance within the County and cities of western Riverside County. Hence, adoption and implementation of either the Existing Reserve or the No Project/No Action Alternatives would have a less than significant impact on population, housing and employment.

4.3.4 Mitigation Measures

Proposed MSHCP; Listed, Proposed, and Strong Candidate Species Alternative; and Listedand Proposed Candidate Species Alternative

Implementation of the proposed MSHCP; the Listed, Proposed, and Strong Candidate Alternative; the Listed and Proposed Alternative will have a significant impact on population, housing, or employment because the Plan and each of these Alternatives will indirectly induce substantial population growth in the Plan Area by providing take authorization for the species covered by the plans proposed in those alternatives. There is no feasible means of mitigating this significant environmental impact.

Existing Reserves and No Project/No Action Alternative

Implementation of the Existing Reserves or the No Project/No Action Alternatives would not have any significant impact on population, housing, or employment. Therefore, no mitigation measures are required.

4.3.5 Significance of Impacts after Mitigation

Proposed MSHCP; Listed, Proposed, and Strong Candidate Species Alternative; and Listed and Proposed Species Alternative

As explained above, there is no feasible means of mitigating the significant indirect impact on population, housing and employment. The MSHCP; the Listed, Proposed and Strong Candidate Alternative; and the Listed and Proposed Species Alternative all create criteria-based reserve systems that would remove an impediment to growth by authorizing take of listed species within the Plan Area. Thus, the MSHCP and each of these Alternatives will indirectly induce substantial population growth in the Plan Area. This impact is significant and unavoidable.

Neither the Project (the MSHCP) nor any of the Alternatives will have a significant impact concerning: (1) displacement of people or substantial numbers of existing housing, or (2) the jobs-to-housing imbalance. Therefore, no mitigation of these impacts is required.

Existing Reserves and No Project/ No Action Alternative

The Existing Reserves and the No Project/No Action Alternative will not have any significant direct or indirect impact on population, housing, or employment.

4.4 Public Services (Fire Protection and Parks)

4.4.1 Impact Analysis Considerations and Assumptions

Fire

Impacts to fire protection would occur if the Proposed MSHCP or an alternative eliminated fire protection resources, prevented planned development of a fire station, restricted needed roadway access to provide protection to an area, interfered with existing fire prevention programs, or increased the risk of fires.

Parks

In each alternative, existing parks are considered acceptable land uses within the Conservation Area and would not be removed. While some modification to trail systems might occur to protect sensitive resources, the possible loss of access to certain areas would be offset by the overall increase in open space recreation opportunities, including additional trails. (This would not apply to the Existing Reserves Alternative, which would be unlikely to modify existing parks.) Regional and Historic Trails are covered activities with the proposed MSHCP. Community trails are existing uses which would also be permitted with the proposed Plan. Bike trails are addressed in the Transportation and Circulation section, and would not be affected by the proposed MSHCP. Impacts to parks would occur mainly in the areas where future parks are planned but have not been developed. Should such areas fall within the boundaries of an alternative, the development of park facilities would be restricted to compatible uses. Facilities such as playgrounds, outdoor amphitheaters, ball fields, and other uses that can significantly modify the natural environment might not be permitted in certain areas.

4.4.2 Thresholds of Significance/Criteria for Determining Significance

The proposed MSHCP would have a significant effect on parks and the ability to provide fire protection if implementation of the alternative would result in the need for deletion or relocation of fire protection services or of existing or planned parks, and such deletion or relocation would have adverse effects on the ability of local jurisdictions to provide fire protection and park facilities in an adequate manner to residents of the region.

4.4.3 Impacts

Fire

Proposed MSHCP. The proposed MSHCP would not directly result in additional development, nor would it involve expansion of wildlands. Thus, the risk of wildland fires would not increase, as the urban-wildland edge would not change. However, the proposed MSHCP would accommodate growth in areas outside of the Conservation Areas. Thus, indirect effects could occur as development in the non-conserved regions approaches the edges of the Conservation Areas. It is anticipated that adequate fire protection facilities will be provided to accommodate the increased development at the time such development occurs. Furthermore, as existing fire protection facilities are located in public/quasi-public lands, and as additional fire protection facilities are allowed to be constructed within Conservation Areas, the configuration of Conservation Areas would not limit fire protection access in the Plan Area. Thus, no existing or planned fire protection facilities would require deletion or relocation as a result of the proposed MSHCP.

Setting aside areas for conservation within larger natural areas would allow cities and the County to plan appropriate land uses along the anticipated urban-wildland border. This could indirectly result in decreased risk of wildland fire damage by placing compatible land uses and necessary buffer areas along the edges of the Conservation Areas.

Listed, Proposed, and Strong Candidate Species Alternative. The Listed, Proposed, and Strong Candidate Species Alternative would not directly result in additional development, nor would it involve expansion of wildlands. Thus, the risk of wildland fires would not increase, as the urban-wildland edge would not change. However, the proposed MSHCP would accommodate growth in areas outside of the Conservation Areas. Thus, indirect effects could occur as development in the non-conserved regions approaches the edges of the Conservation Areas. It is anticipated that adequate fire protection facilities will be provided to accommodate the increased development at the time such development occurs. Furthermore, as existing fire protection facilities are located in public/quasi-public lands, and as additional fire protection facilities are allowed to be constructed within Conservation Areas, the configuration of Conservation Areas would not limit fire protection access in the Plan Area. Thus, no existing or planned fire protection facilities would require deletion or relocation as a result of this alternative. Indirect effects would be similar to the proposed MSHCP.

Listed and Proposed Species Alternative. The Listed and Proposed Species Alternative would not directly result in additional development, nor would it involve expansion of wildlands. Thus, the risk of wildland fires would not increase, as the urban-wildland edge would not change. However, the proposed MSHCP would accommodate growth in areas outside of the Conservation Areas. Thus, indirect effects could occur as development in the non-conserved regions approaches the edges of the Conservation Areas. It is anticipated that adequate fire protection facilities will be provided to accommodate the increased development at the time such development occurs. Furthermore, as existing fire protection facilities are located in public/quasi-public lands, and as additional fire protection facilities are allowed to be constructed within Conservation Areas, the configuration of Conservation Areas would not limit fire protection access in the Plan Area. Thus, no existing or planned fire protection facilities would require deletion or relocation as a result of this alternative. Indirect effects would be similar to the proposed MSHCP.

Existing Reserves and No Project Alternatives. The Existing Reserves and No Project Alternatives would not directly result in additional development, nor would it involve expansion of wildlands. Thus, the risk of wildland fires would not increase, as the urban-wildland edge would not change as a result of this alternative. Development would continue to occur outside of the reserve areas, and it is anticipated that fire protection facilities would be constructed to serve the additional development as required by applicable ordinances and planning documents. Fire protection facilities are permitted, and could be constructed in reserve areas as needed. Thus, the Existing Reserves and No Project Alternatives would not result in the deletion or relocation of existing or future fire protection facilities. The potential indirect benefit of fire-safe planning would be significantly reduced under this alternative, as impacts to species would require setting aside natural areas whose location would not be predictable.

Parks

Proposed MSHCP. As discussed, no impact would occur to existing park facilities. Planned park facilities that are located within the Conservation Area of the proposed MSHCP would be subject to potential restrictions contained in the Reserve Criteria for the cell in which the park is located. Recreational use is considered to be a conditionally compatible use within proposed the MSHCP Conservation Area. Five planned park facilities are proposed within the Conservation Area of the proposed MSHCP, as indicated in Table 4 AAX. All of these parks are located near edges of the Conservation Area, which would facilitate public access. Thus, the proposed MSHCP would not require the deletion or relocation of planned parks.

The preservation of natural land may provide additional opportunities for recreation. As recreational use is included as a conditionally compatible use within the Conservation Area, the protected areas may result in higher-quality natural areas for public enjoyment. Thus, planned park facilities may be supplemented by recreational opportunities available in the Conservation Area.

Listed, Proposed, and Strong Candidate Species Alternative. Planned park facilities that are located within the Conservation Area of the Listed, Proposed, and Strong Candidate Species Alternative would be required to comply with any applicable MSHCP regulations. Recreational use is considered to be a conditionally compatible use within the MSHCP Conservation Area. Seven planned park facilities are proposed within the Conservation Area of this alternative, as indicated in Table 4 AAX. All of these parks are located near edges of the Conservation Area, which would facilitate public access. Thus, the Listed, Proposed, and Strong Candidate Species Alternative would not require the deletion or relocation of planned park facilities. Indirect beneficial effects would be similar to the proposed MSHCP, though as less land would be set aside, proportionately fewer acres of additional recreational resources would be expected.

Listed and Proposed Species Alternative. Planned park facilities that are located within the Conservation Area of the Listed and Proposed Species Alternative would be required to comply with any applicable MSHCP regulations. Recreational use is considered to be a conditionally compatible use within MSHCP Conservation Areas. Seven planned park facilities are proposed within the Conservation Area of this alternative, as indicated in Table 4AAX. All of these parks are located near edges of the Conservation Area, which would facilitate public access. Thus, the Listed and Proposed Species Alternative would not require the deletion or relocation of planned parks. Indirect beneficial effects would be similar to the proposed MSHCP, though as less land would be set aside, proportionately fewer acres of additional recreational resources would be expected.

Existing Reserves and No Project Alternatives. One planned park facility, the College Park in Moreno Valley, is located within the Existing Reserves and No Project Alternatives area. As parks and recreational activities are allowed within existing reserves, no alteration of the planned facility would be required, and no significant impact would occur.

Table 4AAX - Summary of Impacts to Planned Park Facilities

Cotton Wood Park (Aguanga)	In	In	In	Out	Out

College Park (Moreno Valley)	In	In	In	In	Out

Analysis of Significance

None of the proposed alternative scenarios (including the proposed MSHCP) would result in the deletion or relocation of park or fire protection facilities. Thus, no significant impacts would occur.

4.4.4 Mitigation Measures

As no significant impacts would occur, no mitigation measures are required.

4.4.5 Level of Significance after Mitigation

Impacts to parks and fire protection would be less than significant for each of the alternative scenarios.

4.5 Transportation and Circulation

4.5.1 Introduction

The existing circulation and transportation system serving the proposed MSHCP Plan Area is composed of a series of separate modes or types of passenger travel and goods movement. These modes of travel and goods movement include passenger vehicles and truck freight, transit, passenger and freight rail, passenger and cargo air, and non-motorized systems (bicycle facilities, pedestrian facilities, and equestrian facilities).

In each alternative, existing roadways are considered acceptable land uses and would not be removed. While the construction of planned roadways (as identified in Figure 7.1 of the MSHCP) is a covered activity, the design, sitting, and construction of these planned roadways will be subject to guidelines outlined in the MSHCP to ensure consistency with the objectives of the MSHCP.

Transportation-related impacts would generally occur where the use or improvement of existing roadways or construction of planned roadways was prohibited, resulting in reduced levels of service, increased congestion, or reduced access.

4.5.2 Thresholds of Significance/Criteria for Determining Significance

The proposed MSHCP and alternatives would have a significant effect on the operation of transportation facilities if they:

Cause an increase in traffic that is substantial in relation to the existing traffic load and capacity of the street system (i.e., result in a substantial increase in either the number of vehicle trips, the volume to capacity ratio on roads, or congestion at intersections);
Exceed, either individually or cumulatively, a level of service standard established by the county congestion management agency for designated roads or highways;
Substantially increase hazards due to a design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment);
Result in inadequate emergency access; and/or
Conflict with adopted policies, plans, or programs supporting alternative transportation (e.g., bus turnouts, bicycle racks).

4.5.3 Impacts

Existing and Planned Roadways

Proposed MSHCP

Existing Roadways. There are many existing roadways within public/quasi-public lands, including interstates, freeways, State highways, city- and County-maintained roadways, as well as local roads, which are not city- or County-maintained, that provide property access. This latter category of roadways is generally maintained by the adjacent property owners, either individually or collectively. Necessary operation and maintenance activities conducted for safety purposes will be permitted within public/quasi-public lands. Therefore, there will be no significant impact on existing roadways and emergency access within public/quasi public lands.

Some of the existing County/City-maintained unpaved roads may be paved within the existing roadbed as future traffic, safety and/or environmental conditions warrant. In addition, safety improvements to other publicly maintained existing roadways within public/quasi-public lands are covered activities. Therefore, there will be no significant impact on existing roadways and emergency access within public/quasi public lands for roadways owned by the County.

Maintenance activities on roadways maintained by others are afforded limited coverage, subject to the submittal of an application for Certificate of Inclusion. The covered maintenance activities for these roadways are substantially limited in scope, including only such grading as necessary to restore a smooth driving surface, maintain existing graded shoulders within the existing rights-of way, and essential weed abatement, excluding the application of any herbicides. Therefore, there will be no significant impact on existing roadways and emergency access within public/quasi public lands for privately owned roadways.

Planned Roadways. Coverage of new planned road facilities within existing public/quasipublic lands is limited to the Hemet to Corona/Lake Elsinore CETAP Corridor. In the areas where these impacts occur, the estimated width of right-of-way for the corridor is approximately 500 feet. This facility will potentially include the following elements:

Three mixed-flow lanes in each direction;
One high-occupancy vehicle (HOV) lane in each direction;
Shoulders at Caltrans standards for freeways;
Medians of sufficient width to accommodate Caltrans standard median widths, including an exclusive transitway, either rail or bus; and
Buffer areas and areas for utilities.

No interchanges are proposed within existing public/quasi-public lands. Any interchanges that may be proposed in the future with public/quasi-public lands will not be covered.

Planned roadways are defined as either existing facilities that require improvements (e.g., widening) or new facilities to be constructed. Planned roadways include seven types of roadways (expressways, urban arterials, arterials, major roads, mountain arterials, secondary roads, and collector roads), freeways, CETAP corridors, and other major facilities that have been identified as part of the General Plan circulation element. The specific location for planned roads, bridges and interchanges are not exact. The ultimate alignment and design will be determined during project-level engineering, and approval for the alignment will include appropriate environmental review pursuant to CEQA. The ultimate alignment and design of the facility will be subject to the design, siting, and construction guidelines outlined in the MSHCP.

Approximately 5,840 acres of roads will be improved/constructed within the Criteria Area. The improvement/construction as well as the operation and maintenance of circulation element roadways are covered activities within the Criteria Area, subject to guidelines described in the MSHCP.

State freeways within the MSHCP Plan Area include I-215, I-15, I-10, SR-60, and SR-91. Freeways are operated and maintained by Caltrans. Caltrans has identified preliminary improvements for these facilities that are included in the analysis as Covered Activities.

Two CETAP transportation corridors are proposed to be located within the MSHCP Plan Area: a north-south CETAP transportation corridor from Winchester to Temecula, and an east-west transportation corridor from Hemet to Corona/Lake Elsinore. Multiple alternatives for each CETAP corridor are currently being contemplated; however, only one east-west corridor and one north-south corridor will be selected and built. The estimated width of right-of-way for the CETAP corridors ranges between approximately 500 and 1,000 feet. The facilities will potentially include the following elements:

Three mixed-flow lanes in each direction;
One HOV lane in each direction;
Shoulders at Caltrans standards for freeways;
Medians of sufficient width to accommodate Caltrans standard median widths, including an exclusive transitway, either rail or bus;
Buffer areas and areas for utilities; and
Interchanges at locations to be identified.

The San Bernardino to Moreno Valley corridor is not proposed to be covered under the MSHCP. The selected alternative for the Orange County-Riverside County corridor would be considered a covered activity under the MSHCP (subject to the provisions and conditions set forth in the MSHCP).

Planned roadways are proposed within the County and cities to facilitate planned growth. Planned roadways identified in Section 7.3.5 of the MSHCP are covered activities within the Criteria Area. Roadways other than those identified in Section 7.3.5 of the MSHCP are not covered without an amendment of the MSHCP. The MSHCP includes design and sitting guidelines for planned roadways. The implementation of these guidelines will ensure that planned roadways are designed and constructed in a manner consistent with the objectives of the MSHCP, while providing for the efficient passage of persons and goods through western Riverside County, the alleviation of traffic congestion, the maintenance of level of service standards, and continuation of adequate emergency access/evacuation routes. Therefore, the proposed MSHCP would not have significant impacts on planned roadways.

Listed, Proposed, and Strong Candidate Species Alternative. The operation, maintenance, and construction of the existing and planned roadways identified in Section 7.0 of the MSHCP are required for the efficient movement of persons and goods through western Riverside County. Under this alternative, the location and alignment of existing and planned transportation facilities will be unchanged from that identified in the Proposed Action; therefore, potential impacts resulting from implementation of this alternative would be identical to those occurring under the Proposed Action.

Listed and Proposed Species Alternative. The operation, maintenance, and construction of the existing and planned roadways identified in Section 7.0 of the MSHCP is required for the efficient movement of persons and goods through western Riverside County. Under this alternative, the location and alignment of existing and planned transportation facilities will be unchanged from that identified under the Proposed Action; therefore, potential impacts resulting from implementation of this alternative would be identical to those occurring under the Proposed Action.

Existing Reserves Alternative. Under this alternative, the land use changes and policies being contemplated to implement the proposed MSHCP would not occur. Planning currently being conducted for the County's General Plan and Countywide circulation element could still be adopted. Implementation of the various elements of those plans may result in the take of listed species and regulated habitats. Under the Proposed Action, the maintenance construction of roadways, freeways, CETAP corridors, and other major facilities identified as part of the General Plan circulation element are covered activities. Because this alternative will maintain the current inventory of roadways and because planned roadways are identical to those identified under the Proposed Action, potential impacts to transportation facilities under the Existing Reserves Alternative would be identical to those resulting from implementation of the Proposed Action.

No Project Alternative. Impacts resulting from development activities are currently subject to a variety of local, State, and Federal regulatory processes. Under this alternative, activities involving take of State and/or Federal listed species would require individual permitting on a project-by-project basis.

As with the Proposed Action, planned roadways under this alternative are those roadways identified in the cities' and County General Plan Circulation elements. Because this alternative will maintain the current inventory of roadways and because planned roadways are identical to those identified under the Proposed Action, potential impacts to transportation facilities under the No project alternative would be identical to those resulting from implementation of the Proposed Action.

Analysis of Significance

Guidelines detailed in Section 7.0 of the MSHCP would avoid and minimize impacts to sensitive species and habitats known to occur in the vicinity of planned roadways, while permitting the construction, operation, and maintenance of roadways. The operation, maintenance, and construction of existing and planned roadways is necessary for the efficient and effective passage of persons and goods through western Riverside County, the alleviation of traffic congestion, the maintenance of level of service standards, and continuation of adequate emergency access/evacuation routes. As the operation, maintenance, and construction of existing and planned roadways, detailed in Section 7.0 of the MSHCP, are covered activities within the Conservation Area, potential transportation-related impacts resulting from implementation of the Proposed Action or its alternatives will be less than significant.

4.5.4 Mitigation Measures

Because impacts associated with this issue are less than significant, no mitigation measures are required.

4.5.5 Level of Significance after Mitigation

Transportation-related impacts would be less than significant for the proposed MSHCP and each of the alternative scenarios.
