GENERAL BIOLOGICAL RESOURCES AND MSHCP COMPLIANCE REPORT JUNE 2009 LAKE ELS INORE MOTOCROSS FACILITY CITY OF LAKE ELSINORE EXECUTIVE SUMMARY LSA Associates, Inc. (LSA)was retained by the City of Lake Elsinore to prepare necessary biological reports to comply with the Western Riverside County Multiple Species Habitat Conservation Plan (MSHCP) for the Lake Elsinore Motocross Facility Conditional Use Permit (CUP) Project. The project action (project) is the approval of a CUP that will allow changes in operation of an existing motocross facility. Changes associated with the proposed project include permitting the use of the facility by off-road trucks and similar vehicles on a track located at the northwestern corner of the site;the use of nighttime lighting to allow operation of the facility from 8:00 a.m. to 10:00 p.m.; and addition of an outdoor seating area adjacent to the multiuse track at the northwest corner of the site. The project site is located partially within the Lake Elsinore Area Plan, Subunit 3 of the MSHCP. The project is located within the Criteria Area; however, the development does not conflict with MSHCP criteria for conservation. The project site is located within the MSHCP Burrowing Owl Survey Area, Criteria Area Species Survey Area (CASSA), and Narrow Endemic Plant Species Survey Area (NEPSSA). All necessary surveys to comply with MSHCP requirements at this time have been conducted and the proposed project is in compliance with the MSHCP. RACLE0901\Bio\CLE0901 MSHCP Compliance Rpt.doc(6/24/2009) ] LSA ASSOCIATES, INC. GENERAL BIOLOGICAL RESOURCES AND MSHCP COMPLIANCE REPORT JUNE 2009 LAKE ELS INORE MOTOCROSS FACILITY CITY OF LAKE ELSINORE 1.0 INTRODUCTION LSA Associates, Inc. (LSA) was retained to conduct a general biological resources assessment at the existing Lake Elsinore Motocross Facility located at Assessor's Parcel No. (APN)370-030-012 in the City of Lake Elsinore (City), Riverside County (County), California. The facility is located adjacent to Skylark Field, west of Corydon Street, and south of Mission Trail. LSA biologists reviewed relevant background information and visited the site to assess for existing biological resources and determine potential project impacts on these resources. 2.0 PROJECT LOCATION AND DESCRIPTION The study area consists of approximately 89.5 acres and is located approximately 0.75 mile east of Interstate 15 (I-15).It is northwest of Corydon Street and south and west of Mission Trail.The project site is located on the U.S. Geological Survey (USGS) 7.5-minute Lake Elsinore, California quadrangle in a portion of the southeast '/4 of Section 16 and northeast '/a of Section 21, Township 6 South,Range 4 West(Figure 1). The proposed project is the approval of a Conditional Use Permit (CUP) that will allow changes in operation of the existing motocross facility. The proposed CUP would permit the use of the facility by off-road trucks and similar vehicles on an existing track located at the northwestern corner of the site. The project also includes the use of portable,diesel-generator powered lighting.Lighting features will consist of up to 30 lighting units, with each unit consisting of four 1,000-watt fixtures. The portable lighting fixtures will be mounted on standards measuring up to 30 feet in height. As needed, lighting will be provided between the hours of 5:00 and 10:00 (November through March); 6:00 and 10:00 p.m. (April through May, and October);and 7:00 and 10:00 p.m. (June through September). The project also includes addition of an outdoor seating area to a sloped area adjacent to the multiuse track at the northwest corner of the site. The site of the proposed outdoor seating area is heavily disturbed and is devoid of vegetation. The seating area will be seeded and maintained with a turf surface. The seating area will measure approximately 17 feet in height and will include 4-foot wide benches on which temporary seating(e.g., lawn chairs)provided by the track operator can be used. No other changes to the existing facility are proposed. Patrons of the facility will continue to utilize the existing tracks located on site. Parking will continue to consist of hard packed dirt surfaces. No improved curbs, wheel stops, or pavement will be installed. Operation of the motocross facility will continue the existing maintenance regimen, which consists of daily and weekly track repair including the refacing of jumps and "ripping" of tracks to allow moisture into the soil to assist with dust control. Water trucks are cycled through the site to apply water to tracks, access roads, and parking areas to assist with dust control. Appendix A provides the conceptual layout of the motocross facility incorporating the proposed changes in operating conditions.

GENERAL BIOLOGICAL RESOURCES AND MSHCP COMPLIANCE REPORT JUNE 2009 LAKE ELSINORE MOTOCROSS FACILITY CITY OF LAKE ELSINORE 3.0 REGULATORY BACKGROUND 3.1 Jurisdictional Waters and Streambeds The U.S. Army Corps of Engineers (ACOE), under Section 404 of the Federal Clean Water Act (CWA), regulates discharges of dredged or fill material into "waters of the United States." These waters include wetlands and non-wetland bodies of water that meet specific criteria, including a connection to interstate or foreign commerce. This connection may be direct (through a tributary system linking a stream channel with traditional navigable waters used in interstate or foreign commerce) or it may be indirect (through a connection identified in ACOE regulations). The ACOE typically regulates as non-wetland waters of the U.S. any body of water displaying an"ordinary high water mark." In order to be considered a jurisdictional wetland under Section 404, an area must possess hydrophytic vegetation,hydric soils, and wetland hydrology. On January 9, 2001, the United States Supreme Court narrowly limited the ACOE jurisdiction of "non-navigable, isolated, intrastate"waters based solely on the use of such waters by migratory birds. The Court ruling derives from the case Solid Waste Agency of Northern Cook County(SWANCC) v. U.S. Army Corps of Engineers, No. 99-1178. The Supreme Court, in a 5-4 decision, determined the ACOE exceeded its statutory authority by asserting CWA jurisdiction over an abandoned sand and gravel pit in northern Illinois that provides habitat for migratory birds. In 2006, the Supreme Court in the consolidated cases Rapanos v. United States and Carabell v.Army Corps of Engineers (Rapanos) addressed CWA jurisdiction over wetlands adjacent or abutting navigable, non-navigable and ephemeral tributaries; jurisdiction over permanent and relatively permanent non-navigable tributaries (126. CT.2208 (2006), 33 U.S.C. §1251 et seq.). The CWA does not assert jurisdiction over upland erosional features, gullies, and roadside ditches that have infrequent, low volume, and short duration of water flow. In addition, ACOE uses a significant nexus analysis. Application of this standard will involve a comprehensive review of the tributary flow characteristics, functions of the tributary, and functions of any adjacent wetlands. The analysis involves completion of a seven-page "Approved Jurisdiction Form." The ACOE uses the standard to determine if the tributary or wetland significantly affects the hydrological, ecological, chemical, physical, and biological integrity of the downstream navigable water. Additional information is provided in United States Environmental Protection Agency (EPA)memorandum titled"Clean Water Act Jurisdiction Following the U.S. Supreme Court's Decision in Rapanos v. United States & Carabell v. United States," dated June 5, 2007 (ACOE 2007), and also the U.S. Army Corps of Engineers Jurisdictional Determination Form Instructional Guidebook(ACOE and EPA 2007). The California Department of Fish and Game (CDFG), under Sections 1600 et seq. of the California Fish and Game Code, regulates alterations to lakes, rivers, and streams. A stream is defined by the presence of a channel bed and banks, and at least an occasional flow of water. The CDFG also regulates habitat associated with the streambed, such as wetland, riparian shrub,and woodlands. The Regional Water Quality Control Board (RWQCB) is responsible for the administration of Section 401 of the CWA, through water quality certification of any activity that may result in a discharge to jurisdictional waters of the U.S. The RWQCB may also regulate discharges to"waters of the State," including wetlands,under the California Porter-Cologne Water Quality Control Act. RACLE0901\Bio\CLE0901 MSHCP Compliance Rptdoc(6/24/2009) 4 LSA ASSOCIATES, INC, GENERAL BIOLOGICAL RESOURCES AND MSHCP COMPLIANCE REPORT JUNE 2009 LAKE ELSINORE MOTOCROSS FACILITY CITY OF LAKE ELSINORE 3.2 MSHCP Compliance The Western Riverside County Multiple Species Habitat Conservation Plan (MSHCP) provides for the assembly of a Conservation Area consisting of Core Areas and Linkages for the conservation of Covered Species (Riverside County 2003). Covered Species are 146 species of plants and animals of various federal and State listing statuses. The Conservation Area is to be assembled from portions of the MSHCP Criteria Area, which consists of quarter-section(i.e., 160-acre) Criteria Cells, each with specific criteria for the species conservation within that cell. The MSHCP provides an incentive- based program,the Habitat Evaluation and Acquisition Negotiation Strategy(HANS)for adding land to the MSHCP Conservation Area. If it is determined that all or a portion of the property is needed for inclusion in the MSHCP Conservation Area,then various incentives may be available to the property owner in exchange for the conveyance of a property interest. The MSHCP requires focused surveys for certain plant, amphibian, owl, and mammal species for project sites located within designated plant and animal survey areas when potential suitable habitat is present. Surveys for Delhi Sands flower-loving fly (Rhaphiomidas terminatus abdominalis) may be required in areas having Delhi soils. Surveys for listed riparian birds are required when suitable riparian habitat is present, and surveys for listed fairy shrimp species are required when vernal pools or other suitable habitat is present. Projects located in proximity to the MSHCP Conservation Area may result in edge effects that could adversely affect biological resources within the MSHCP Conservation area. MSHCP Urban/Wildlands Interface Guidelines (MSHCP Section 6.1.4) are intended to reduce such indirect effects. 3.3 California Environmental Quality Act Compliance(CEQA) 3.3.1: Adopted Habitat Conservation Plans. Section 10(a)(2)(A) of the 1973 Federal Endangered Species Act(FESA) requires the preparation of a habitat conservation plan(HCP) for incidental take of threatened or endangered species when there is no federal agency involvement in a project. Continuing land development may cause incidental take of listed species and, therefore, HCPs have been prepared for areas within western Riverside County. The MSHCP and the Stephens' Kangaroo Rat Habitat Conservation Plan are the principal habitat conservation plans in western Riverside County. The U.S. Fish and Wildlife Service (USFWS) regional office maintains a current list of habitat conservation plans for the southern California region. 3.3.2: Threatened and Endangered Species. The USFWS or CDFG may list species as threatened or endangered under the FESA or California Endangered Species Act (CESA), respectively. The USFWS can designate critical habitat that identifies specific areas, either occupied or unoccupied, that are essential to the conservation of a listed species. Critical habitat areas may require special management considerations or protections. The USFWS and CDFG have issued permits for the take of most threatened and endangered species within the MSHCP Plan Area. The MSHCP and related EIR/EIS address impacts to these species. However, if a project has the involvement of a federal agency, that agency is required to address impacts to listed species and critical habitat by consulting with the USFWS. The USFWS has RACLE090I\Bio\CLE0901 MSHCP Compliance RpLdoc(6/24/2009) 5 LSA ASSOCIATES, INC. GENERAL BIOLOGICAL RESOURCES AND MSHCP COMPLIANCE REPORT JUNE 2009 LAKE ELSINORE MOTOCROSS FACILITY CITY OF LAKE ELSINORE indicated in the permit issued for the MSHCP that, in such cases, the consultation will be expedited and that no restrictions will be imposed on the project beyond those specified in the MSHCP. 3.3.3: Other Special Interest Species. Other special interest species may occur on the proposed project site. The CDFG, USFWS, local agencies, and special interest groups, such as the California Native Plant Society(CNPS), maintain lists of species that they consider to be in need of monitoring. Legal protection for special interest species varies widely. 3.3.4: Wildlife Movement, Corridors, and Nursery Sites. Wildlife movement includes seasonal migration along corridors, as well as daily movements for foraging. Migration corridors may include areas of unobstructed movement of deer,riparian corridors providing cover for migrating birds,routes between breeding waters and upland habitat for amphibians, and between roosting and feeding areas for birds. During the avian nesting season(typically February 1 through August 31), large trees(greater than 15 to 70 feet in height)may be used by hawks,ravens, or other large birds for nesting. Trees, shrubs, and other vegetation may provide nest sites for smaller birds, and burrowing owls may nest in abandoned ground squirrel burrows, pipes, or similar features. Most birds and their active nests are protected from "take" (meaning destruction, pursuit, possession, etc.) under the Migratory Bird Treaty Act (USFWS 2002) and/or Sections 3503-3801 of the California Fish and Game Code (CDFG 2007). Activities that cause destruction of active nests, or that cause nest abandonment and subsequent death of eggs or young, may constitute violations of one or both of these laws. Removal of vegetation shall be conducted outside of nesting season to avoid impacts to nesting birds. 3.3.5: Natural Communities of Interest. Riparian habitats, oak woodlands, and vernal pools are among the natural communities of interest to the CDFG. Coastal sage scrub is not considered a sensitive natural community unless it is occupied by coastal California gnatcatcher (Polioptila californica californica) or has been declared designated critical habitat for the California gnatcatcher by the USFWS. 3.3.6: Wetlands. Wetlands as defined by the ACOE must possess hydrophytic vegetation, hydric soils, and wetland hydrology under normal circumstances. In order to be considered a vernal pool under the MSHCP, a depression must also meet these three wetland criteria. 3.3.7: Local Policies and Ordinances Protecting Biological Resources. City and County General Plans and development ordinances may include regulations or policies governing biological resources. For example, policies may include tree preservation, locally designated species survey areas, local species of interest, and significant ecological areas (Riverside County Planning Department 2006).

GENERAL BIOLOGICAL RESOURCES KEAELSI NOREPMOTOCROSS FACILITY CITY OF LAKE ELSINORE JUNE 2009 3.3.8: Direct Effects.Direct effects are impacts that occur at the same time and in the location of the actual construction work. associated with construction e potential to result in the destruction, disturbance, and removal of plats, anmals, watercourses, and natural communities. 3.3.9: Indirect Effects. Indirect effects are impacts caused by the project action but are later in time or farther in distance from the actual construction work. Indirect effects include growth inducement, changes in land use patterns, increased human intrusion, population growth, noise,and impacts to air quality, wind movements, water quality, hydrology, plant communities, wildlife movement, and regional ecosystems. 3.3.10: Cumulative Effects. According to Section 15130 of the CEQA Guidelines (Consulting Engineers and Land Surveyors of California 2007), cumulative impacts refer to incremental effects of an individual project when viewed in connection with the effects of past projects, current projects, and probable future projects. 4.0 METHODS 4.1 Literature Review A literature review was conducted to determine the existence or potential occurrence of special-status plant and animal species on the project site and in the project vicinity. Database records for the Lake Elsinore, California; Alberhill, California; Wildomar, California; and Romoland, California USGS 7.5-minute quadrangles were searched on June 8,2009, using the CDFG Natural Diversity Data Base Rarefind 3 application (version 3.1.0, dated January 4, 2009) and the California Native Plant Society's Electronic Inventory of Rare and Endangered Vascular Plants of California(online edition, v7-07d, 2007, http://www.cnps.org/inventory). An aerial photograph (AirPhoto USA 2008) was reviewed and Geographic Information Systems(GIS)software generated maps of USFWS designated critical habitats(USFWS 1994,2005, 2006,2007, and 2008) were used to determine the locations of critical habitats relative to the project site. Volume 1,Parts 1 and 2 of the Western Riverside County Multiple Species Habitat Conservation Plan were also used to prepare the biological resources report. Soil information was taken from Soil Survey of Western Riverside Area, California (Soil Conservation Service 1971)and electronic data provided by Soil Data Mart(MRCS 2003). 4.2 Field Surveys The general biological resources assessment included a site visit on May 21, 2009, by LSA Biologist Sarah Barrera. Habitat suitability assessments for Narrow Endemic Plant Species, Criteria Area Survey Species,and burrowing owl (Athene cunicularia h u aea were conducted at this time. Field surveys were conducted following applicable survey protocols or guidelines for each species. 7 RACLE0901\Bio\CLE0901 MSHCP Compliance Rpt_doc(6/24/2009) COMPLIANCE REPORT GENERAL BIOLOGICAL RESOURCES AEAELSINOREFMOTOCROSS FACILITY LSA ASSOCIATES.

A large patch of Water is also indicated on the soils map(Figure 2). Historic aerials reveal that the Water portions of the site were inundated with water as recently as 1980 (http://historicaerials.com/). Soils observed on site were alkaline, and in the less disturbed northeastern and southeastern areas fit the description for Wa. The rest of the site contains imported,compacted soils used to build the motocross tracks. 5.4 Wildlife Wildlife common to disturbed areas was observed, including house finch (Carpodacus mexicanus), song sparrow (Melospiza melodia), house sparrow (Passer domesticus), California ground squirrel (Spermophilus beecheyi), and coyote (Canis latrans). A complete list of wildlife species observed on the site is included in Appendix B. Trees and shrubs on site may provide nesting habitat to birds observed using the site and surrounding areas. It is recommended that construction activities within 250 feet of trees and shrubs be scheduled outside of the avian nesting season(February 15 to August 15). If construction activities are planned during the avian nesting season, a pre-construction nesting bird survey should be conducted within three days prior to commencement to avoid impacts to birds protected under the Migratory Bird Treaty Act(MBTA). 5.5 Potential Jurisdictional Wetlands and Streambeds Any activities resulting in fill, discharge or alteration of a lake, river or streambed are subject to jurisdiction by the CDFG, ACOE, and/or RWQCB. No areas potentially under agency jurisdiction occur on site. Although several plant species common to wet areas occur on site,these are present due to the use of watering trucks used to minimize dust from the motocross tracks. Runoff water collects in lower areas of the site and allows vegetation requiring higher amounts of water to survive. No indicators of water flow (i.e., water marks, sediment deposits, drift deposits, and drainage patterns) were observed within the study area. Therefore,this portion of the project would not be considered to be under the jurisdiction of CDFG or ACOE. A water quality Certification or Waste Discharge Requirements from the RWQCB will not be required. The findings and conclusions presented in this report, including the location and extent of wetlands and other waters subject to regulatory jurisdiction, represent the professional opinion of LSA. These findings and conclusions should be considered preliminary until verified by the resource agencies. 6.0 MSHCP COMPLIANCE A portion of the study area is located within MSHCP Criteria Area Cell 5131 (Figure 3).This cell lies within the Elsinore Area Plan, Subunit 3. Specific conservation measures have been developed for this portion in accordance with its location within the MSHCP. These criteria were identified by conducting a search on the Riverside County Integrated Project (RCIP) Conservation Summary Report Generator. The remainder of the study area is not within a criteria cell and is not subject to conservation criteria associated with a Criteria Area Cell.

GENERAL BIOLOGICAL RESOURCES AND MSHCP COMPLIANCE REPORT ,TUNE 2009 LAKE ELSINORE MOTOCROSS FACILITY CITY OF LAKE ELSINORE 6.3 Overall Consistency with MSHCP and Reserve Assembly Criteria A portion of the project area is located within Criteria Cell 5 13 1.Areas identified within this cell are targeted for conservation, which will contribute to extension of Existing Core 3. Extension of this Core is intended to conserve grassland habitat and soils associated with Lake Elsinore. Within Cell 5131, 30 to 40 percent of the southwestern portion is targeted for conservation. An existing access road and highly disturbed tamarisk scrub vegetation currently comprise this portion of the study area. No new activities are proposed within the portion of the project area located within Cell 5131. Approval of the CUP will not result in the loss of grassland habitat or interfere with habitat or soils associated with Existing Core 3. The project is located within a highly disturbed area and surrounded by existing recreational and commercial land uses. Use of the project site as proposed will not conflict with MSHCP conservation objectives for the area. The proposed project is consistent with the MSHCP and MSHCP Reserve Assembly and will not be required for conservation. 6.3.1: Cores and Linkages. A Linkage is 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. A Core is a block of habitat that supports the life history requirements of Covered Species. The proposed project site lies within a cell containing land identified for potential use to extend Existing Core 3. According to the MSHCP, this extension consists of two blocks of land extending from the southern border of Existing Core 3. It is intended to conserve Traver series soils which provide habitat for several Narrow Endemic Plant Species. The northern portion of the extension also provides for movement of species along the lower San Jacinto River to Proposed Linkage 8(Sedco Hills/Wildomar). Potential areas identified for extension of Existing Core 3 are not within the study area; therefore, approval of the CUP will be in compliance with MSHCP conservation goals related to Cores and Linkages. 6.3.2: Planning Species. Planning species are some of the Covered Species identified to be the focus of land conservation objectives for a local area of the MSHCP Plan Area. Planning species are subsets of Covered Species that are identified to provide guidance for Reserve Assembly in Cores and Linkages and/or Area Plans. Planning species for the Elsinore Planning Area, Subunit 3 are listed in Section 6.1.2. Due to the highly disturbed nature of the area, the project site does not provide habitat for most of the planning species for this area. However, a population of smooth tarplant was found in the northeastern corner of the study area, which is not within a criteria cell or CASSA or NEPSSA area. Alkaline soils occur within this corner and throughout the project site. New activities are not proposed within either of these areas and existing tarplant populations will not be affected. The study area does not provide suitable habitat for any of the remaining planning species identified; therefore, impacts will not occur to any planning species and approval of the CUP will be consistent with MSHCP conservation goals related to planning species. RACLE0901\13io\CLE0901 MSHCP Compliance Rpt.doc(6/24/2009) 15 LSA ASSOCIATES. INC. GENERAL BIOLOGICAL RESOURCES AND MSHCP COMPLIANCE REPORT JUNE 2009 LAKE ELSINORE MOTOCROSS FACILITY CITY OF LAKE ELSINORE 6.3.3: Riparian/Riverine and Vernal Pool Requirements. Riparian/riverine areas are lands that contain habitat dominated by trees,shrubs,and persistent emergents, which occur close to or depend upon soil moisture from a nearby water source; or areas with fresh water flowing during all or a portion of the year. Unvegetated drainages(ephemeral streams)may be included if alterations to that drainage have the potential to affect Covered Species and Conservation Areas. No riparian/riverine or vernal pools occur within the portion of the project site within Cell 5131. Plant species indicative of riparian areas, including narrow-leaved cattail, rabbitfoot grass, and alkali bulrush, occur in small patches throughout the bare ground/disturbed areas of the project site. These species are growing in depressions that exist as a result of creation and maintenance of the motocross tracks and associated parking facilities. Water from water trucks used multiple times daily to reduce dust from the tracks collects in these depressions and provides sufficient water to support riparian vegetation species.However,these depressions are not naturally occurring and sufficient water would not exist to support this vegetation without artificial water sources. A small patch of arroyo willow trees, also associated with riparian areas, occurs in the northeast corner of the study area. No above-ground water sources were observed in this area and the trees likely either receive water from an underground source or from watering trucks. This vegetation will not be affected by the proposed project activities. No other riparian/riverine areas occur in the study area. Project activities will not impact any riparian/riverine areas; therefore, no surveys for riparian birds will be required. Additionally, no vernal pools or similar habitats suitable for special interest fairy shrimp species are present on the project site; therefore, no surveys for fairy shrimp species will be required. The project will avoid all streambed, riparian, and vernal pool habitat. No substantial indirect effects to riparian/riverine areas will occur and approval of the CUP will be consistent with MSHCP conservation goals related to Riparian/Riverine and Vernal Pool Requirements. 6.3.4: Narrow Endemic and Criteria Area Plant Species Survey Area. A small portion of the project site is within MSHCP Survey Area 5 of the NEPSSA and is within a CASSA for plant species (Figure 3). Seven narrow endemic plants and eight criteria area species identified for the study area, listed below: • Narrow Endemic Plants o Munz's onion(Allium munzii); o San Diego ambrosia(Ambrosia pumila); o Many-stemmed dudleya(Dudleya multicaulis); o Spreading navarretia(Navarretia fossalis); o California Orcutt grass(Orcuttia californica); o Hammitt's clay-cress(Sibaropsis hammittii); and o Wright's trichocoronis(Trichocoronis wrightii var.wrightii). R:\CLE0901\Bio\CLE0901 MSHCP Compliance Rpt.doc(6/24/2009) 16 LSA ASSOCIATES, INC. GENERAL BIOLOGICAL RESOURCES AND MSHCP COMPLIANCE REPORT JUNE 2009 LAKE ELS I NORE MOTOCROSS FACILITY CITY OF LAKE ELSINORE • Criteria Area Species o San Jacinto Valley crownscale(Atriplex coronata var.notatior); o Parish's brittlescale(Atriplex parishii); o Davidson's saltscale(Atriplex serenana var. davidsonii); o Thread-leaved brodiaea(Brodiaea filifolia); o Round-leaved filaree(California macrophylla); o Smooth tarplant(Centromadia pungens ssp. laevis); o Coulter's goldfields(Lasthenia glabrata ssp.coulteri); and o Little mousetail(Myosurus minimus ssp.apus). A Habitat Suitability Assessment(HSA)was conducted at the time of the site visit(May 21, 2009)to determine the habitat suitability within the NEPSSA and CASSA areas for the species listed above. The procedures of a focused plant survey entail conducting an HSA to determine if suitable soils and/or if growing conditions are present on site. If so, then a focused plant survey is required during the plant species blooming period. The MSHCP requires that the HSA and focused survey for most of the NEPSSA and CASSA plants be done during a normal rainfall year and/or rainy season. Seasonal rainfall totals at this time were significantly lower than average in 2009, but many annual plants bloomed due to concentrations of rainfall over short periods of time during the rainy season. Soils mapped in the NEPSSA area on site are mapped as water and Wa. Soils mapped in the CASSA area are mapped as Wa. Soil conditions in the water portion of the site are disturbed and plants requiring or preferring alkaline soils, including smooth tarplant, tamarisk, and silverscale occur on site, indicating that Wa soils are likely present in the small portion of the site that is within the NEPSSA. Less than 1 percent of the project site is within the NEPSSA; a small fragment near the western corner and another small fragment at the southwestern corner (see Figure 3). Less than 1 percent of the project site is within the CASSA; a portion of the southeastern corner. The fragment at the southwestern corner is intended to remain vacant and will not be affected by activities associated with the proposed CUP. The fragment at the western corner is highly disturbed as it is currently in use as part of the existing motocross facility. Suitable soils and/or habitat conditions for the fifteen target species do not occur in the NEPSSA or CASSA portions of the site and focused surveys are not required(Table C). Smooth tarplant, a CASSA species, occurs within the northeastern corner of the project site. However, this corner is outside of the CASSA survey area and will not be affected by activities associated with the proposed CUP. No other NEPSSA or CASSA species were observed within the project site. R:\CLE0901\Bio\CLE0901 MSHCP Compliance Rpt.doc(6/24/2009) 17 LSA ASSOCIATES, INC.

The entire project site is within the MSHCP burrowing owl survey area. Burrowing owls are found in open, dry grasslands, agricultural and range lands, and desert habitats often associated with burrowing animals. They can also inhabit grass, forb, and shrub stages of pinyon, and ponderosa pine habitats. They nest in abandoned burrows of ground squirrels or other animals, in pipes, under piles of rock or debris, and in other similar features. Sites within the MSHCP burrowing owl survey area require a burrowing owl habitat suitability assessment, and, if suitable, focused burrowing owl surveys. A habitat suitability assessment and burrow survey for the burrowing owl were conducted in June 2008, according to the MSHCP Burrowing Owl Survey Guidelines (MSHCP October 2005) and California Burrowing Owl Consortium Burrowing Owl Survey Protocol and Mitigation Guidelines (August 2000). Burrowing owls generally forage in short grass (2 to 6 inches in height), mowed and grazed pastures, and ruderal vegetation. Burrowing owls avoid vegetation taller than approximately three feet. Burrowing owls avoid foraging in open fields that do not provide adequate cover from potential predators. An HSA for burrowing owl was conducted at the time of the general biological resources survey (May 21, 2009). The majority of the site does not provide suitable habitat for burrowing owl as it is in use as a motocross facility. Constant vehicle use and grading of track and parking areas preclude burrowing owl establishment. Vegetation within the tamarisk scrub vegetation community at the RACLE0901\Bio\CLE0901 MSHCP Compliance Rpt.doc(6/24/2009) 20 LSA ASSOCIATES, INC. GENERAL BIOLOGICAL RESOURCES AND MSHCP COMPLIANCE REPORT JUNE 2009 LAKE ELS INORE MOTOCROSS FACILITY CITY OF LAKE ELSINORE southeastern portion of the site contains too many trees to provide suitable burrowing owl habitat. Suitable habitat was determined to occur in the disturbed/bare ground vegetation community in the northeastern corner of the site. Vegetation in this area is low and sparse. Several small mammal burrows were observed, as well as a concrete pipe that would provide a suitable burrow (see Figure 2A, Photograph 2).No owls or owl sign(pellets, whitewash, feathers,prey remains, etc.)were observed at the time of the HSA. Although suitable burrowing owl habitat occurs in a small portion of the site, focused surveys were not conducted and are not necessary as no activities associated with the proposed CUP will occur in the suitable habitat area of the site. Areas with proposed activities associated with the CUP do not provide suitable burrowing owl habitat due to high disturbance. If activities are planned within the northeastern corner of the site where suitable burrowing owl habitat occurs, a focused burrowing owl survey will be required. Impacts to burrowing owls and suitable burrowing owl habitat will not occur and approval of the CUP will be consistent with MSHCP conservation goals related to Burrowing Owl Requirements. 6.3.6: Other MSHCP Survey Requirements. The project site is not within designated MSHCP survey areas for any other animal species, nor does the site contain Delhi series soils. Therefore, no surveys for other animal species are necessary for MSHCP consistency. 6.3.7: Urban/Wildlands Interface Requirements. The MSHCP Conservation Area is to be assembled from portions of the Criteria Area and existing Public/Quasi-Public Lands. Any development in proximity to the MSHCP Conservation Area may result in edge effects that adversely affect biological resources within the MSHCP Conservation Area. The guidelines provided in MSHCP Section 6.1.4 (Guidelines Pertaining to the Urban/Wildlands Interface) are intended to reduce such edge effects. The guidelines describe mitigation for project effects related to drainage, toxics, lighting, noise,invasive species, barriers,grading, and land development. The study area is not adjacent to any proposed or existing MSHCP Conservation Area lands; therefore,MSHCP Section 6.1.4 Guidelines do not apply to this project 7.0 CEQA COMPLIANCE 7.1 Adopted Habitat Conservation Plans The project site is within the MSHCP area. Other adopted Habitat Conservation Plans (HCPs) in the area include the Stephens' Kangaroo Rat HCP. The project site is not within the Stephens' Kangaroo Rat Habitat Conservation Plan(SKR HCP)fee area. The project site is not subject to any other adopted HCP. 7.2 Threatened and Endangered Species No threatened or endangered species occur on the project site. The site is not within designated critical habitat of any species. The nearest designated critical habitat is for the California gnatcatcher RACLE0901\Bio\CLE0901 MSHCP Compliance Rp4doc(6124/2009) 21 LSA ASSOCIATES. INC. GENERAL BIOLOGICAL RESOURCES AND MSHCP COMPLIANCE REPORT ,TUNE 2009 LAKE ELSINORE MOTOCROSS FACILITY CITY OF LAKE ELSINORE (CAGN) approximately 1.5 miles northeast of the proposed project site. Critical habitat for Munz's onion occurs approximately 3 miles southwest of the proposed project site. No suitable habitat for CAGN, Munz's onion, or any other threatened or endangered species occurs on site. No impacts will occur to listed species. 7.3 Other Special Interest Species The special interest species listed in Table D may be expected to occur in the general project vicinity but are not covered under the MSHCP or are not adequately conserved by the MSHCP at this time. None of these species is expected to occur on the project site due to lack of suitable soils and/or habitat. None of these species is listed as threatened or endangered under state or federal law. Therefore, any impacts to these species by the project would not be substantial. Neither additional surveys nor additional conservation measures will be required by this project for these species.

P Species is covered but not considered adequately conserved pending completion of MSHCP specified requirements. 7.4 Wildlife Movement,Corridors,and Nursery Sites Wildlife movement includes seasonal migration along corridors, as well as daily movements for foraging and reaching water sources. Migrational corridors may include areas of unobstructed movement for deer, riparian corridors providing cover for migrating birds, routes between breeding waters and upland habitat for amphibians, and between roosting and feeding areas for birds. The project site is not adjacent to any existing or proposed linkage or core areas as identified in the MSHCP. The site is surrounded by recreational and commercial uses on the south and east. A small amount of open space occurs to the north, but residential development less than '/3 of a mile north of the site blocks any potential wildlife movement in this direction. Undeveloped areas of the site could provide wildlife movement for species associated with Lake Elsinore to the west; however,there is no habitat to the east to which the site would provide a connection. There are no nursery sites, such as bat roosting sites or bird rookeries, on the project site. R:\CLE090I\Bio\CLE0901 MSHCP Compliance Rpt.doc(6/24/2009) 25 LSA ASSOCIATES. INC. GENERAL BIOLOGICAL RESOURCES AND MSHCP COMPLIANCE REPORT JUNE 2009 LAKE ELSINORE MOTOCROSS FACILITY CITY OF LAKE ELSINORE 7.5 Natural Communities of Interest Riparian habitats, oak woodlands, wetlands, aquatic sites, and vernal pools are among the natural communities of interest to the CDFG. No native plant communities considered sensitive or of special concern to the CDFG or USFWS are present on the project site;therefore, no impacts are expected. 7.6 Wetlands There are no features that might be considered vernal pools on the project site. No plant communities that might be considered sensitive are present on the project site. There are no wetlands on the project site. Additionally, the project will not result in any fill, grade or excavation of waters of the U.S., or removal of riparian vegetation. 7.7 Local Policies and Ordinances Protecting Biological Resources County General Plans and development ordinances may include regulations or policies governing biological resources. For example, policies may include tree preservation, locally designated species survey areas, local species of interest, and significant ecological areas. There are no other local ordinances applicable to biological resources except for code provisions related to the MSHCP mitigation fee and land credits. The project will not be in conflict with any local policies or ordinances applicable to biological resources. 7.8 Indirect Effects Indirect impacts to surrounding areas as a result of the project may include, but are not limited to, increased dust, noise, lighting, and traffic. Expanded use of the existing dirt tracks as proposed in the CUP will result in increased dust and new use of night lighting. Dust will be minimized through the use of watering trucks on a regular basis, as is the current practice. The proposed CUP envisions operation of the facility from 8:00 a.m. to 10:00 p.m. Currently, the motocross facility does not provide any nighttime lighting. Lighting features will consist of up to 30 lighting units, with each unit consisting of four 1,000-watt fixtures. As needed, lighting will be provided between the hours of 5:00 and 10:00 p.m. (November through March); 6:00 and 10:00 p.m. (April through May, and October); and 7:00 and 10:00 p.m. (June through September). Night lighting is regulated under Section 17.112.400 of the City's Municipal Code and Riverside County Ordinance 655. These regulations require directing lights and using shielding to prevent direct overhead illumination and prevent any glare or direct illumination on adjacent properties or streets. Light and glare from portable lighting fixtures and vehicles entering/exiting the project site will increase lighting sources in the project area. However, the site is located within an urbanizing area of the City, which already experiences some levels of light and/or glare from the existing buildings, vehicles, and streetlights. Additionally the site is not adjacent to the MSHCP Conservation Area or any wildlife movement areas or corridors.

GENERAL BIOLOGICAL RESOURCESLAKE ELSINORE AND pMOTOCROSS FACILITY JUNE 2009 CITY OF LAKE ELSINORE Because the lighting will adhere to City and County regulations requiring shielding and other efforts to reduce glare or illumination,substantial indirect impacts to wildlife in adjacent habitat as a result of night lighting would not be substantial.Other indirect impacts are not anticipated. 7.9 Cumulative Effects Cumulative impacts potentially include habitat fragmentation, increased edge effects, reduced habitat quality, and increased wildlife mortality.No new development will occur and no loss of any existing biological resources is expected. The project's contributions to cumulative biological impacts are not expected to be cumulatively considerable. 27 RACLE0901\Bio\CLE0901 MSHCP Compliance Rpt doc(6/24/2009) LSA ASSOCIATES, INC.
