Ronald Reagan Park Project
1 July 2023
2022-252.03

1.0 INTRODUCTION
ECORP Consulting, Inc. conducted a biological reconnaissance survey at an approximately 27-acre property for the proposed Ronald Reagan Park Project (Project) in the City of Wildomar in Riverside County. The Project also includes offsite improvement areas. The survey was conducted to identify any potential biological resources that could be affected by the Proposed Project, pursuant to the terms of the California Environmental Quality Act (CEQA) and for the purposes of identifying any biological constraints that would affect the proposed site plan for the Project. The surveys were conducted in accordance with the Western Riverside County Multiple Species Habitat Conservation Plan (MSHCP). The MSHCP provides information on plant and wildlife species of concern to the County of Riverside and outlines goals for their conservation. Information on the MSHCP can be found at www.rctlma.org (Riverside County Transportation and Land Management Agency [RCTLMA] 2023). The Project will be subject to county, state, and federal regulations regarding compliance with the federal Endangered Species Act (ESA), California ESA, Migratory Bird Treaty Act (MBTA), and California Fish and Game Code.

1.1 Project Location
The Project is generally located east of Interstate 15 and north of Clinton Keith Road. The Project Area is located west of Wildomar Trail, north of La Estrella Street, and east of Susan Drive, in the City of Wildomar, Riverside County, California (Figures 1 and 2). The Project Area measures approximately 27 acres and comprises Assessor Parcel Numbers (APNs) 376-350-009 and 376-350-017.

The Project, as depicted on the U.S. Geological Survey (USGS) Murrieta, California 7.5-minute topographic quadrangle map, is located within Section 36 of Township 6 South, Range 4 West. The Project Area is gently sloped with higher elevations in the northeastern corner and lower elevations in the southwestern corner. Elevations range from approximately 1,390 to 1,500 feet (424 to 457 meters) above mean sea level.

The Project Area is currently vacant land covered primarily with California buckwheat (Eriogonum fasciculatum) scrub within the northern portions, and a mix of non-native black mustard (Brassica nigra) and other non-native forbs within the southern portions. Disturbances onsite include several dirt roads used by pedestrians and off-highway vehicles and the presence of off-leash dogs and trash.

1.2 Project Description
The Project proposes to construct a 27-acre park with 221 parking spaces; five driveways (two along Wildomar Trail, one along La Estrella Street, and two along Susan Drive); and amenities, including bike trails and a bike plaza, a fitness plaza, a fire station, a splash pad, playgrounds, volleyball courts, gardens, a community green area, a community center, an amphitheater, shade structures, lookout points, trails, bridge crossings, interpretive signs, bioretention/biofiltration areas, and a connection to Ronald Reagan Elementary School.

Offsite improvements would include full frontage improvements on La Estrella Street, Susan Drive, and Wildomar Trail, including curb, gutter, sidewalk, and street lighting improvements, as well as pavement widening. The Project would also include sewer and potable water main extensions along both La Estrella Street and Susan Drive. The areas of offsite roadway improvements are not addressed in this Biological Technical Report.

1.3 Terms
The following terms will be used throughout this document and are defined as follows:
 Project Area: the approximately 27-acre property, comprising APNs 376-350-009 and 376-350- 017, assessed during the general biological assessment that will be permanently impacted to construct the park and associated amenities.
 Burrowing Owl Study Area: includes the Project Area and a 500-foot survey buffer.

2.0 SPECIAL-STATUS SPECIES REGULATIONS
ECORP conducted the biological reconnaissance survey to identify potential constraints to development and to ensure compliance with state and federal regulations regarding listed, protected, and sensitive species. The regulations are detailed below.

2.1 Federal Regulations

2.1.1 The Federal Endangered Species Act
The federal ESA protects plants and animals that are listed as endangered or threatened by the U.S. Fish and Wildlife Service (USFWS) and the National Marine Fisheries Service. Section 9 of the federal ESA prohibits the taking of endangered wildlife, where taking is defined as “harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, collect, or attempt to engage in such conduct” (50 Code of Federal Regulations [CFR] 17.3). For plants, this statute governs removing, possessing, maliciously damaging, or destroying any endangered plant on federal land and removing, cutting, digging up, damaging, or destroying any endangered plant on non-federal land in knowing violation of state law (16 U.S. Code 1538). Under Section 7 of the federal ESA, federal agencies are required to consult with the USFWS if their actions, including permit approvals or funding, could adversely affect a listed or proposed species, including plants or its critical habitat. Through consultation and the issuance of a biological opinion, the USFWS may issue an incidental take statement allowing take of the species that is incidental to an otherwise authorized activity provided the activity will not jeopardize the continued existence of the species. Section 10 of the federal ESA provides for issuance of incidental take permits where no other federal actions are necessary provided a Habitat Conservation Plan (HCP) is developed.

2.1.2 Migratory Bird Treaty Act
The federal MBTA implements international treaties between the United States and other nations devised to protect migratory birds, any of their parts, eggs, and nests from activities such as hunting, pursuing, capturing, killing, selling, and shipping, unless expressly authorized in the regulations or by permit. As 866
Biological Technical Report and Western Riverside County MSHCP Consistency Analysis ECORP Consulting, Inc.

Ronald Reagan Park Project
5 July 2023
2022-252.03
authorized by the MBTA, the USFWS issues permits to qualified applicants for the following types of activities: falconry, raptor propagation, scientific collecting, special purposes (i.e., rehabilitation, education, migratory game bird propagation, and salvage), take of depredating birds, taxidermy, and waterfowl sale and disposal. The regulations governing migratory bird permits can be found in 50 CFR Part 13 General Permit Procedures and 50 CFR Part 21 Migratory Bird Permits. The State of California has incorporated the protection of birds of prey in Sections 3800, 3513, and 3503.5 of the California Fish and Game Code.

2.1.3 Federal Clean Water Act
The purpose of the federal Clean Water Act (CWA) is to “restore and maintain the chemical, physical, and biological integrity of the nation’s waters.” Section 404 of the CWA prohibits the discharge of dredged or fill material into Waters of the U.S. without a permit from the U.S. Army Corps of Engineers (USACE). The definition of Waters of the U.S. includes rivers, streams, estuaries, the territorial seas, ponds, lakes, and wetlands. Wetlands are defined as those areas “that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions” (33 CFR 328.3 7b). The U.S. Environmental Protection Agency acts as a cooperating agency to set policy, guidance, and criteria for use in evaluation permit applications and reviews USACE permit applications.

The USACE regulates fill or dredging of fill material within its jurisdictional features. Fill material means any material used for the primary purpose of replacing an aquatic area with dry land or changing the bottom elevation of a water body. Substantial impacts to wetlands may require an individual permit.

Projects that only minimally affect wetlands may meet the conditions of one of the existing Nationwide Permits. A Water Quality Certification or waiver pursuant to Section 401 of the CWA is required for Section 404 permit actions; this certification or waiver is issued by the State Water Quality Control Board, administered by each of nine California Regional Water Quality Control Boards (RWQCB).

2.2 State and Local Regulations

2.2.1 California Endangered Species Act
The California ESA generally parallels the main provisions of the federal ESA; however, unlike its federal counterpart, the California ESA applies the take prohibitions to species proposed for listing (called candidates by the State). Section 2080 of the California Fish and Game Code prohibits the taking, possession, purchase, sale, and import or export of endangered, threatened, or candidate species, unless otherwise authorized by permit or in the regulations. Take is defined in Section 86 of the California Fish and Game Code as “hunt, pursue, catch, capture, or kill, or attempt to hunt, pursue, catch, capture, or kill.” The California ESA allows for take incidental to otherwise lawful development projects. State lead agencies are required to consult with the California Department of Fish and Wildlife (CDFW) to ensure that any action they undertake is not likely to jeopardize the continued existence of any endangered or threatened species or result in destruction or adverse modification of essential habitat. 867

6 July 2023
2022-252.03

2.2.2 Fully Protected Species
The State of California first began to designate species as fully protected prior to the creation of the federal and California ESAs. Lists of fully protected species were initially developed to provide protection to those animals that were rare or faced possible extinction, and included fish, amphibians and reptiles, birds, and mammals. Most fully protected species have since been listed as threatened or endangered under federal and/or California ESAs. The regulations that implement the Fully Protected Species Statute (California Fish and Game Code Section 4700) provide that fully protected species may not be taken or possessed at any time. Furthermore, CDFW prohibits any state agency from issuing incidental take permits for fully protected species, except for necessary scientific research.

2.2.3 Native Plant Protection Act
The Native Plant Protection Act (NPPA) of 1977 (California Fish and Game Code Sections 1900-1913) was created with the intent to “preserve, protect and enhance rare and endangered plants in this State.” The NPPA is administered by CDFW. The Fish and Wildlife Commission has the authority to designate native plants as endangered or rare and to protect endangered and rare plants from take. The California ESA of 1984 (California Fish and Game Code Section 2050-2116) provided further protection for rare and endangered plant species, but the NPPA remains part of the California Fish and Game Code.

2.2.4 California Fish and Game Code

2.2.4.1 Streambed Alteration Agreement
Section 1602 of the California Fish and Game Code requires that a Notification of Lake or Streambed Alteration be submitted to CDFW for “any activity that may substantially divert or obstruct the natural flow or substantially change the bed, channel, or bank of any river, stream, or lake.” The CDFW reviews the proposed actions and, if necessary, submits to the Applicant a proposal for measures to protect affected fish and wildlife resources. The final proposal that is mutually agreed upon by CDFW and the Applicant is the Streambed Alteration Agreement (SAA). Often, projects that require an SAA also require a permit from the USACE under Section 404 of the CWA. In these instances, the conditions of the Section 404 permit and the SAA may overlap.

2.2.4.2 Migratory Birds
The CDFW enforces the protection of nongame native birds in Sections 3503, 3503.5, and 3800 of the California Fish and Game Code. Section 3513 of the California Fish and Game Code prohibits the possession or take of birds listed under the MBTA. These sections mandate the protection of California nongame native birds’ nests and make it unlawful to take these birds. All raptor species are protected from take pursuant to California Fish and Game Code Section 3503.5 and are also protected at the federal level by the MBTA of 1918 (USFWS 1918).

2.2.5 Western Riverside County Multiple Species Habitat Conservation Plan The Western Riverside County MSHCP is a comprehensive, multijurisdictional HCP focusing on conservation of species and their associated habitats in western Riverside County. The MSHCP identified 146 species, referred to as Covered Species, for which the federal and California ESAs take authorization has been granted to signatories to the plan as long as they comply with its requirements. Of the 146 Covered Species within the MSHCP, 118 are considered to be adequately conserved. The remaining 28 Covered Species will be considered adequately conserved when certain landmark conservation requirements are met during the course of future development. The goal of the MSHCP is to maintain the biological and ecological diversity within a rapidly urbanizing region while also improving the future economic development in the county by providing an efficient, streamlined regulatory process through which development can proceed in an efficient way.

The approval of the MSHCP and execution of the Implementing Agreement (IA) by the wildlife agencies allows signatories of the IA to issue take authorizations for all species covered by the MSHCP, including state- and federally listed species, as well as other identified sensitive species and/or their habitats. Each city of local jurisdiction will impose a development mitigation fee for projects within their jurisdiction.

With payment of the mitigation fee to the County and compliance with the survey requirements of the MSHCP where required, full mitigation in compliance with CEQA, National Environmental Policy Act (NEPA), and the federal and California ESAs, will be granted. The development mitigation fee varies according to project size and description and is dependent on development density (Riverside County Ordinance No. 810.2). Payment of the mitigation fee and compliance with the requirements of Section 6.0 of the MSHCP are intended to provide full mitigation under CEQA, NEPA, and the California and federal ESAs for impacts to the species and habitats covered by the MSHCP, pursuant to agreements with USFWS, CDFW, and/or any other appropriate participating regulatory agencies as set forth in the IA for the MSHCP.

2.2.6 Stephens’ Kangaroo Rat (Dipodomys stephensi) Habitat Conservation Plan The Project Area is located within the Long-Term Stephens’ kangaroo rat HCP area. The plan is administered by the Riverside County Habitat Conservation Agency (RCHCA) and aims to conserve 15,000 acres of occupied Stephens’ kangaroo rat habitat. To date, more than 46,000 acres have been assembled in western Riverside County for this species. The RCHCA has a Section 10A permit granted by USFWS that allows for take of Stephens’ kangaroo rat as part of development activity. The federal ESA defines take as any attempt to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture or collect, or to attempt to engage in any such conduct as it relates to Stephens’ kangaroo rat. As individual projects are proposed and approved in the Stephens’ kangaroo rat HCP area, public and private land developers are required to pay a Stephens’ kangaroo rat mitigation fee for land that is developed and removes Stephens’ kangaroo rat habitat. This streamlined process benefits developers in the Stephens’ kangaroo rat HCP Area because projects within this area do not require individual review and approval by the wildlife agencies.

Developers benefit from the streamlined process in the Stephens’ kangaroo rat HCP area because projects within this area do not require individual review and approval by the wildlife agencies. The activities covered by the plan fall into three categories:
869
Biological Technical Report and Western Riverside County MSHCP Consistency Analysis ECORP Consulting, Inc.

Ronald Reagan Park Project
8 July 2023
2022-252.03

1. Actions by private landowners, local and regional public agencies, public and private utilities, and farmers that are otherwise lawful but constitute incidental take of Stephens’ kangaroo rat as defined by the federal and California ESA;

2. Establishment and management of permanent Stephens’ kangaroo rat reserves by the RCHCA in cooperation with other public agencies and individual landowners; and

3. Implementation by the RCHCA and its member agencies of the conservation, mitigation, and monitoring measures specified in this plan.

The Mitigation Fee is $500 per gross acre of the parcels proposed for development within the Stephens’ kangaroo rat HCP Area.

2.2.7 California Environmental Quality Act Significance Criteria Section 15064.7 of the CEQA Guidelines encourages local agencies to develop and publish the thresholds the agency uses in determining the significance of environmental effects caused by projects under its review. However, agencies may also rely upon the guidance provided by the expanded Initial Study checklist contained in Appendix G of the CEQA Guidelines. Appendix G provides examples of impacts that would normally be considered significant. Based on these examples, impacts to biological resources would normally be considered significant if the project would:
 have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by CDFW or USFWS;
 have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations or by CDFW or USFWS;  have a substantial adverse effect on state or federally protected wetlands (including, but not limited to, marsh, vernal pool, and coastal) through direct removal, filling, hydrological interruption, or other means;
 interfere substantially with the movement of any native resident or migratory fish or wildlife species, or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites;
 conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance; and
 conflict with the provisions of an adopted HCP, Natural Community Conservation Plan, or other approved local, regional, or state HCP.

An evaluation of whether an impact on biological resources would be substantial must consider both the resource itself and how that resource fits into a regional or local context. Substantial impacts would be those that would diminish, or result in the loss of, an important biological resource, or those that would obviously conflict with local, state, or federal resource conservation plans, goals, or regulations. Impacts 870

are sometimes locally important but not significant according to CEQA because although the impacts would result in an adverse alteration of existing conditions, they would not substantially diminish or result in the permanent loss of an important resource on a population-wide or region-wide basis.

3.0 METHODS

3.1 Literature Review
Prior to conducting the biological reconnaissance survey, ECORP biologists performed a literature review using the CDFW’s California Natural Diversity Database (CNDDB; CDFW 2023a) and the California Native Plant Society (CNPS) Electronic Inventory (CNPSEI; CNPS 2023) to determine the documented specialstatus plant and wildlife species in the vicinity of the Project Area. ECORP searched CNDDB records within 5 miles of the Project and searched CNPSEI records within the USGS Murrieta, California 7.5-minute topographic quadrangle map. Because the Project lies within the northwest corner of the Murrieta Quadrangle, the adjacent three topographic quadrangles (Lake Elsinore, Romoland, and Wildomar) were also included in the CNPSEI records search. The CNDDB and CNPSEI contain records of reported occurrences of federally or state-listed endangered, threatened, proposed endangered or threatened species, California Species of Special Concern (SSC), and/or other special-status species or habitat that may occur within or in the vicinity of the Project. Additional information was gathered from the following sources and includes, but is not limited to:
 U.S. Department of Agriculture, Natural Resources Conservation Service (NRCS) Web Soil Survey (NRCS 2023);
 State and Federally Listed Endangered and Threatened Animals of California (CDFW 2023b);  State and Federally Listed Endangered, Threatened, and Rare Plants of California (CDFW 2023c);  Special Animals List (CDFW 2023d);
 Special Vascular Plants, Bryophytes, and Lichens List (CDFW 2023e);  Information for Planning and Consultation (IPaC) (USFWS 2023a);  The Jepson Manual: Vascular Plants of California (Baldwin et al. 2012);  A Manual of California Vegetation, 2nd Edition (MCV; Sawyer et al. 2009); and  Various online websites (e.g., CalFlora 2023).

Using this information and field observations, ECORP biologists generated a list of special-status plant and wildlife species that have potential to occur within the Project Area. For the purposes of this assessment, special-status species are defined as plants or animals that:
 have been designated as either rare, threatened, or endangered by CDFW, CNPS, or the USFWS, and/or are protected under either the federal or California ESAs;  are candidate species being considered or proposed for listing under these same acts; 871
Biological Technical Report and Western Riverside County MSHCP Consistency Analysis ECORP Consulting, Inc.

Ronald Reagan Park Project
10 July 2023
2022-252.03
 are fully protected by the California Fish and Game Code, Sections 3511, 4700, 5050, or 5515;  are of expressed concern to resource and regulatory agencies or local jurisdictions; and/or  are covered species under the MSHCP.

ECORP assessed special-status species reported for the region in the literature review or for which suitable habitat occurs within the Project Area for their potential to occur within the Project Area based on the following guidelines:
 Present: The species was observed onsite during a site visit or focused survey.  High: Habitat (including soils and elevation factors) for the species occurs within the Project Area and a known occurrence has recently been recorded (within the last 20 years) within 5 miles of the area.
 Moderate: Habitat (including soils and elevation factors) for the species occurs within the Project Area and a documented observation occurs within the database search, but not within 5 miles of the area; a historic documented observation (more than 20 years old) was recorded within 5 miles of the Project Area; or a recently documented observation occurs within 5 miles of the area and marginal or limited amounts of habitat occurs within the Project Area.  Low: Limited or marginal habitat for the species occurs within the Project Area and a recently documented observation occurs within the database search, but not within 5 miles of the area; a historic documented observation (more than 20 years old) was recorded within 5 miles of the Project Area; or suitable habitat strongly associated with the species occurs onsite, but no records or only historic records were found within the database search.  Presumed Absent: Species was not observed during a site visit or focused surveys conducted in accordance with protocol guidelines at an appropriate time for identification; habitat (including soils and elevation factors) does not exist onsite; or the known geographic range of the species does not include the Project Area.

Note: Location information on some special-status species may be of questionable accuracy or unavailable. Therefore, for survey purposes, the environmental factors associated with a species’ occurrence requirements may be considered sufficient reason to give a species a positive potential for occurrence. In addition, just because a record of a species does not exist in the databases does not mean it does not occur. In many cases, records may not be present in the databases because an area has not been surveyed for that particular species.

3.2 U.S. Fish and Wildlife Service-Designated Critical Habitat Biologists reviewed the USFWS online service for information regarding Threatened and Endangered Species Final Critical Habitat designation within California to determine if the Project is within any species’ designated Critical Habitat (USFWS 2023b).

11 July 2023
2022-252.03

3.3 Aquatic Resources
ECORP biologists conducted a desktop review of the NRCS Web Soil Survey (NRCS 2023), USFWS National Wetlands Inventory (USFWS 2023c), and the corresponding USGS topographic maps to determine if there were any blue line streams or drainages that might potentially fall under the jurisdiction of either federal or state agencies within the Project Area.

3.4 Western Riverside County MSHCP Consistency Analysis ECORP reviewed Project data to determine consistency with the MSHCP. Biologists queried the Riverside Conservation Authority (RCA) MSHCP Information Map to determine requirements for habitat assessment(s), potential focused survey(s), or other issues related to biological resources that could exist within the Project Area (RCA 2023a).

Section 6.0 of the MSHCP also requires that an assessment of the Project be completed to identify any potential applicable Project-related effects on biological resources, including riparian/riverine areas, vernal pools, and fairy shrimp. In addition, the MSHCP requires that an Urban/Wildlands Interface analysis be conducted to address the indirect effects associated with locating proposed development in the proximity of MSHCP Conservation Areas.

3.5 Field Survey

3.5.1 Biological Reconnaissance Survey
Biologists conducted a reconnaissance survey by walking the entire Project Area paying special attention to those areas that could host sensitive vegetation communities or had the potential to provide suitable habitat for special-status species. The biologists documented the plant and wildlife species present within the Project Area and assessed the location and condition of the Project for the potential to provide habitat for special-status plant and wildlife species. The data was recorded on a Global Positioning System (GPS) unit, field notebooks, and/or maps. Photographs were taken during the survey to provide visual representation of the various vegetation communities within the Project Area. The biologists examined the Project Area to assess its potential to facilitate wildlife movement or function as a movement corridor for wildlife moving throughout the region. In addition, the biologists mapped the vegetation communities and land cover types present within the Project Area and the 500-foot survey buffer surrounding the Project Area. The following minimum mapping units were used during vegetation mapping: 0.25 acre for sensitive vegetation communities and 1.0 acre for non-sensitive vegetation communities.

ECORP inspected the vegetation communities and habitat conditions to confirm presence and habitat quality of the vegetation found onsite. Where appropriate, biologists utilized descriptions of vegetation communities from the MCV second edition (Sawyer et al. 2009). Any deviations from standard vegetation classifications were made on best professional judgment when areas did not fit into a specific habitat description provided by the MCV. Biologists mapped vegetation communities using field observations and aerial imagery.
873
Biological Technical Report and Western Riverside County MSHCP Consistency Analysis ECORP Consulting, Inc.

Ronald Reagan Park Project
12 July 2023
2022-252.03
ECORP recorded plant and wildlife species including any special-status species that were observed during the survey. Plant nomenclature follows that of The Jepson Manual: Vascular Plants of California (Baldwin et al. 2012). Wildlife nomenclature follows Society for the Study of Amphibians and Reptiles (2017), Checklist of North American Birds (Chesser et al. 2019), and the Revised Checklist of North American Mammals North of Mexico (Bradley et al. 2014). ECORP recorded GPS coordinates, the species, location, and habitat in instances where a special-status species was observed.

3.5.2 Burrowing Owl Habitat Assessment and Focused Burrow Survey The Project is located within the MSHCP Burrowing Owl (BUOW; Athene cunicularia) Survey Area (Figure 3) and is subject to the MSHCP burrowing owl survey requirements (RCA 2023a). ECORP conducted a BUOW habitat assessment concurrently with the biological reconnaissance survey to determine the presence of suitable habitat. Biologists walked the Project Area and a 500-foot buffer (Figure 3) to identify the presence of owl habitat, scanning for suitable habitat using binoculars in areas that were inaccessible by foot. ECORP biologists determined that suitable burrowing owl habitat occurs onsite, therefore, a focused burrow survey was performed concurrently with the habitat assessment. All encountered suitable burrows were marked during the May 30 habitat assessment and focused burrow survey.

4.0 RESULTS
The results of the literature review and field survey, including site characteristics, vegetation communities, wildlife, special-status species, and special-status habitats (including any potential wildlife corridors) are summarized below.

4.1 Literature Review

4.1.1 Special-Status Plants and Wildlife
ECORP conducted the CNDDB, CNPSEI, and IPaC searches on May 22, 2023. The database searches identified 48 special-status plant species and 32 special-status wildlife species that could occur within or near the Project Area. Biologists generated a list from the results of the literature review and evaluated the Project Area for suitable habitat that could support any of the special-status plant or wildlife species on the list.

4.1.2 U.S. Fish and Wildlife Service-Designated Critical Habitat The Project is not located within any USFWS-designated critical habitat. The closest designated critical habitat is for coastal California gnatcatcher (Polioptila californica californica), approximately 0.5 mile northeast of the Project Area (USFWS 2023b).

4.2.1 Site Characteristics and Land Use
The Project Area is currently vacant, and the vegetation observed is primarily composed of native scrub and non-native forbs. Dirt roads transect the Project Area and are used by pedestrians and off-highway vehicles. The biologists also observed scattered trash and off-leash dogs within the Project Area.

Additionally, areas along the perimeter of the Project Area showed evidence of mechanical disturbance, likely associated with annual weed and fire abatement procedures.

The NRCS Web Soil Survey (2023) identified seven soil types within the Project Area:
 Cieneba sandy loam, 5 to 8 percent slopes
 Cieneba sandy loam, 15 to 50 percent slopes, eroded
 Cieneba rocky sandy loam, 15 to 50 percent slopes, eroded  Fallbrook sandy loam, 8 to 15 percent slopes, eroded
 Hanford coarse sandy loam, 2 to 8 percent slopes
 Monserate sandy loam, 0 to 5 percent slopes
 Placentia fine sandy loam, 5 to 15 percent slopes
The Project Area is bounded by Ronald Reagan Elementary School and residential development to the east, an open lot to the north, an open lot and residential development to the south, and low-density rural residences to the west. Representative site photographs are included in Appendix A. 876

4.2.2 Vegetation Communities and Land Cover Types
ECORP identified two vegetation alliances and one additional land cover type within the Project Area and the 500-foot survey buffer surrounding the Project Area. Detailed descriptions of each of these vegetation/land cover types are described below and depicted on Figure 4. A full list of plant species observed within the Project Area and 500-foot survey buffer is included in Appendix B.

4.2.2.1 California Buckwheat Scrub (Eriogonum fasciculatum Shrubland Alliance) California buckwheat scrub occurs within the northern portions of the Project Area and 500-foot survey buffer. California buckwheat scrub is typically dominated or co-dominated by California buckwheat and consists primarily of shrubs less than 2 meters in height with a continuous to intermittent canopy and the herbaceous layer is variable and may be grassy. The areas mapped as this community type were dominated by California buckwheat, California sagebrush (Artemisia californica), deerweed (Acmispon glaber), and purple sage (Salvia leucophylla). Non-native black mustard was also present in some areas classified as California buckwheat scrub. A small stand of coast live oak (Quercus agrifolia) trees is present within this mapped community near the northern boundary of the Project Area; this small area did not meet the minimum mapping unit (described in Section 3.5.1) and was therefore included in this vegetation community type.

4.2.2.2 Upland Mustards (Brassica nigra Herbaceous Semi-Natural Alliance) Upland mustards occurs throughout the Project Area and along the perimeter of the Project Area. This vegetation community was dominated by a mix of non-native forbs and grasses, including black mustard, stinknet (Oncosiphon pilulifer), and foxtail brome (Bromus madritensis). Some areas classified as this community type included native species present to a lesser extent such as rod wirelettuce (Stephanomeria virgata), giant wildrye (Elymus condensatus), deerweed, and turkey-mullein (Croton setiger). A few areas of non-native and native trees/shrubs are included in this mapped community because they are too small to meet the minimum mapping unit (described in Section 3.5.1). This includes a small area of non-native Peruvian peppertree (Schinus molle) and eucalyptus (Eucalyptus sp.) along the western boundary of the Project Area and non-native saltcedar (Tamarix ramosissima) along the eastern boundary. Also included is an area of mixed riparian scrub within the southeastern corner of the Project Area extending southward into the 500-foot survey buffer area; this area is dominated primarily by mulefat (Baccharis salicifolia), coyote brush (Baccharis pilularis), and saltcedar with sparse cover of Fremont cottonwood (Populus fremontii), black willow (Salix gooddingii), and narrowleaf willow (Salix exigua).

4.2.2.3 Disturbed/Developed
The disturbed/developed classification includes: (1) areas where the Project Area has been heavily influenced by human actions, such as off-road use, but lacks development, and (2) areas where anthropogenic disturbance has resulted in permanent impacts such as roads, buildings, and other development. Disturbed/developed areas within the Project Area primarily include dirt roads that lack vegetation cover due to their use by vehicles. Disturbed/developed areas outside of the Project Area but within the 500-foot survey buffer include existing residences, a school, and surface streets. 877

Disturbed/developed is not a vegetation classification, but rather a land cover type and is not typically restricted to a known elevation.

4.2.3 Plants
Plant species observed within the Project Area were composed of both native and non-native species.

Native plant species observed included California buckwheat, California sagebrush, purple sage, coast live oak, and deerweed. Non-native plant species observed included black mustard, foxtail brome, stinknet, saltcedar, and Peruvian peppertree. Appendix B provides a full list of plant species observed on or adjacent to the Project Area.

4.2.4 Wildlife
ECORP biologists observed wildlife species within the Project Area typical of the region. Bird species observed during the reconnaissance survey included red-tailed hawk (Buteo jamaicensis), song sparrow (Melospiza melodia), black phoebe (Sayornis nigricans), and mourning dove (Zenaida macroura). ECORP observed the following mammal species: desert cottontail (Sylvilagus audubonii), California ground squirrel (Otospermophilus beecheyi), and coyote (Canis latrans) scat. Appendix C provides a full list of wildlife species observed on or adjacent to the Project Area.

4.2.5 Potential for Special-Status Species to Occur within the Project Area

4.2.5.1 Special-Status Plants
There were 48 special-status plant species that appeared in the literature review and database searches for the Project Area (CDFW 2023a; CNPS 2023). ECORP generated a list from the results of the literature review and evaluated the Project for suitable habitat that could support any of the special-status plant species on the list.

Several species appeared in the literature review results that had no potential to occur on or near the Project Area due to elevational or habitat requirements. Additionally, biologists eliminated CNPS Rare Plant Rank 3 or 4 species from the analysis (unless they are characterized as MSHCP Covered Species) because these rankings are considered a review list and a watch list, respectively. Table 2 provides descriptions of the CNPS designations. Appendix D consists of a table outlining each plant species, designation, and potential for occurrence within the Project Area.

Note: According to CNPS (Skinner and Pavlik 1994), plants on Lists 1B and 2 meet definitions for listing as threatened or endangered under Section 1901, Chapter 10 of the California Fish and Game Code (California Department of Fish and Game 1984). This interpretation is inconsistent with other definitions.

4.2.5.2 Plant Species Present within the Project Area
One special-status plant species, paniculate tarplant (Deinandra paniculata), was observed in one area of the Project Area during the biological reconnaissance survey. However, paniculate tarplant is a California Rare Plant Rank (CRPR) 4.2 species (limited distribution in California) and is not a species of concern under the MSHCP and CEQA and does not have the same protections that plant species with a rank of 1B.

4.2.5.3 Plant Species with a Moderate Potential to Occur One plant species, Coulter’s matilija poppy (Romneya coulteri; CRPR 4.2, MSHCP Covered Species), was found to have a moderate potential to occur within the Project Area. The site provides suitable disturbed sage scrub and rocky drainage habitat, however, there are no records of the species occurring within 5 miles of the Project Area (Appendix D).

4.2.5.4 Plant Species with a Low Potential to Occur
The following nine (9) species have a low potential to occur within the Project Area because limited habitat for the species occurs onsite and a known occurrence has been reported in the database, but not within 5 miles of the Project Area or a historic documented occurrence (more than 20 years old) was recorded within 5 miles of the Project Area.

4.2.5.5 Plant Species Presumed Absent
A total of 37 plant species were presumed absent from the Project Area due to lack of suitable habitat (including elevation and soils) or because the Project Area is located outside of the known range for the species. A table outlining each species, their designations, and potential for occurrence within the Project Area can be found in Appendix D.

4.2.5.6 Special-Status Wildlife
The literature search documented 32 special-status wildlife species occurrences within 5 miles of the Project Area. ECORP generated a list from the results of the literature review and evaluated the Project for suitable habitat that could support any of the special-status wildlife species on the list. A brief natural history and discussion of the special-status wildlife species found to be present onsite or to have a high/moderate potential to occur within the Project Area is provided below. Appendix E provides a table outlining each species, their designations, and potential for occurrence within the Project Area.

4.2.5.7 Wildlife Species Present within the Project Area No sensitive wildlife species were observed within the Project Area during the biological reconnaissance survey. However, the following species was observed adjacent to the Project Area (within 500 feet).

Coastal California Gnatcatcher
Coastal California gnatcatcher is a federally threatened species, a CDFW Species of Special Concern, and an MSHCP Covered Species. Gnatcatchers are specialists of coastal sage scrub habitat, characterized by low-growing, drought-deciduous, and semi-woody shrubs such as California buckwheat, coast brittlebush (Encelia californica), and California sagebrush. This species nests in relatively dense stands of coastal sage scrub between approximately mid-February to mid-August. This species was heard calling on a slope just north of the Project Area within native habitat composed of California buckwheat, white sage (Salvia apiana), and purple sage. The literature review returned several recent and historic records of occurrences within 5 miles of the Project. USFWS-designated Critical Habitat for the species is located approximately

0.5 mile to the northeast of the Project Area (USFWS 2023b). 881

4.2.5.8 Wildlife Species with a High Potential to Occur Two species were found to have a high potential to occur within the Project Area because habitat (including soils and elevation factors) for the species occurs within the Project Area and a known occurrence has recently been recorded (within the last 20 years) within 5 miles of the area. The specialstatus wildlife species with a high potential to occur are listed below and detailed in Appendix E.  burrowing owl, CDFW SSC, MSHCP Covered Species
 northwestern San Diego pocket mouse (Chaetodipus fallax fallax), CDFW SSC, MSHCP Covered Species

4.2.5.9 Wildlife Species with a Moderate Potential to Occur Seven species were found to have a moderate potential to occur within the Project Area because of one of the following factors:
 Although these species were not observed during the biological reconnaissance survey, somewhat suitable habitat for the species occurs onsite, and a known occurrence has been reported in the database, but not within 5 miles of the Project Area; or  a historic documented observation (more than 20 years old) was recorded within 5 miles of the Project Area; or
 a recently documented observation occurs within 5 miles of the Project Area and marginal or limited amounts of habitat occurs onsite.

The special-status wildlife species with a moderate potential are listed below and detailed in Appendix E.  Bell’s sage sparrow (Artemisiospiza belli belli), CDFW Watch List Species, MSHCP Covered Species  California glossy snake (Arizona elegans occidentalis), CDFW SSC  Crotch bumble bee (Bombus crotchii), State-listed (candidate)  loggerhead shrike (Lanius ludovicianus), CDFW SSC, MSHCP Covered Species  red-diamond rattlesnake (Crotalus ruber), CDFW SSC, MSHCP Covered Species  San Diego black-tailed jackrabbit (Lepus californicus bennettii), CDFW SSC, MSHCP Covered Species
 southern California rufous-crowned sparrow (Aimophila ruficeps canescens), CDFW Watch List Species, MSHCP Covered Species

4.2.5.10 Wildlife Species with a Low Potential to Occur The following seven species have a low potential to occur within the Project Area because of one of the following factors:
882
Biological Technical Report and Western Riverside County MSHCP Consistency Analysis ECORP Consulting, Inc.

Ronald Reagan Park Project
21 July 2023
2022-252.03
 There is limited habitat for the species onsite and a known occurrence has been reported in the database, but not within 5 miles of the Project Area; or  a historic documented observation (more than 20 years old) was recorded within 5 miles of the Project Area; or
 suitable habitat strongly associated with the species occurs onsite, but no records were found in the database search.

The special-status wildlife species with a low potential to occur are listed below and detailed in Appendix E.
 California horned lark (Eremophila alpestris actia), CDFW Watch List species, MSHCP Covered Species
 coast horned lizard (Phrynosoma blainvillii), CDFW SSC, MSHCP Covered Species  coastal whiptail (Aspidoscelis tigris stejnegeri), CDFW SSC, MSHCP Covered Species  orange-throated whiptail (Aspidoscelis hyperythra), CDFW Watch List species, MSHCP Covered Species

 western spadefoot (Spea hammondii), CDFW SSC, MSHCP Covered Species

4.2.5.11 Wildlife Species Presumed Absent
A total of 15 species were presumed absent. These species were not present at the Project Area during the biological reconnaissance survey and the habitat present within the Project Area was not suitable to support these species. For some species, there were historic or recent sightings near the Project Area; however, these species are presumed absent due to the lack of suitable habitat within the Project Area.

Appendix E outlines each species, their designations, and potential for occurrence within the Project Area.

4.3 Burrowing Owl Habitat Assessment
A BUOW habitat assessment was required because the Project is located within the MSHCP-designated BUOW survey area (Figure 5). ECORP biologists Verity Richardson and Carley Adams conducted the BUOW habitat assessment and focused burrow survey concurrently with the biological reconnaissance survey on May 30, 2023 by within the Burrowing Owl Study Area. Weather conditions during the assessment are summarized in Table 1.

The assessment determined that the Project Area included suitable habitat for BUOW primarily within the southern portions of the Project Area consisting of non-native forbs and grasses on level to gently rolling terrain, with an abundance of active California ground squirrel burrows, a few of which could be suitable for BUOW. Therefore, ECORP conducted a focused burrow survey concurrently with the habitat assessment and recorded potential burrows within the Burrowing Owl Study Area (Figure 3). Protocollevel burrowing owl surveys were not performed by ECORP following the habitat assessment and focused burrow survey.

4.4 Raptors and Migratory Birds
Potential nesting habitat for migratory birds and raptors protected by the MBTA and California Fish and Game Code was present on and adjacent to the Project Area in some of the larger trees and shrubs.

Raptors typically breed between February and August, and songbirds and other passerines generally nest between March and August. There is potential for nesting to occur within the Project Area due to the presence of suitable nesting habitat.

4.5 Aquatic Resources Delineation
ECORP conducted a desktop review to identify potential streams and hydric soils on the property. This entailed examination of the NRCS Web Soil Survey (2023), National Wetland Inventory (NWI) mapping, USGS topographic mapping, and historic and recent aerial imagery of the Project Area to aid in identifying potential biological constraints to the Project due to jurisdictional streams. The NWI identified one drainage feature occurring within the Project Area, which flows into the Project Area from the north and exits near the southwestern corner (Figure 6). Based on the desktop review of topographic mapping and historic and recent aerial imagery, two additional drainage features may occur within the Project Area: (1) a drainage feature appears to occur near the southern boundary of the Project Area beginning at the terminus of La Estrella Street where mulefat thickets occur (refer to Figure 4), and (2) a drainage feature appears to occur within the northeastern portion of the Project Area, flowing in a north to south direction into a culvert.

A formal Aquatic Resources Delineation was not performed by ECORP for the Project.

4.6 Wildlife Movement Corridors, Linkages, and Significant Ecological Areas
The concept of habitat corridors addresses the linkage between large blocks of habitat that allow the safe movement of mammals and other wildlife species from one habitat area to another. The definition of a corridor is varied, but corridors may include such areas as greenbelts, refuge systems, underpasses, and biogeographic land bridges. In general, a corridor is described as a linear habitat, embedded in a dissimilar matrix, which connects two or more large blocks of habitat. Wildlife movement corridors are critical for the survivorship of ecological systems for several reasons. Corridors can connect water, food, and cover sources, spatially linking these three resources with wildlife in different areas. 885

In addition, wildlife movement between habitat areas provides for the potential of genetic exchange between wildlife species populations, thereby maintaining genetic variability and adaptability to maximize the success of wildlife responses to changing environmental conditions. This is especially critical for small populations subject to loss of variability from genetic drift and effects of inbreeding. Naturally, the nature of corridor use and wildlife movement patterns varies greatly among species.

ECORP assessed the Project for its ability to function as a wildlife corridor. The Project likely provides wildlife movement opportunities because it consists of open land and there are undeveloped parcels of land to the north and south of the Project Area. A large open space area occurs north of the Project Area, which includes preserved open space areas managed by the RCA; Wildomar Trail Road and several undeveloped parcels of unknown ownership lie between the Project Area and this large, open space habitat to the north. The Project Area is unlikely to function as a wildlife corridor for this open space habitat as no large open space habitats occur directly south, east, or west of the Project.

The Project Area likely plays a minor role in local wildlife dispersal and foraging. Common wildlife species including coyotes, skunks (Mephitis mephitis), opossums (Didelphis virginiana), and raccoons (Procyon lotor) likely travel through the Project Area and neighboring developed and undeveloped areas, but the Project Area does not provide connectivity between large areas of open space on a local or regional scale.

5.0 IMPACT ANALYSIS
Impacts to sensitive biological resources resulting from construction activities are presented below.

5.1 Limitations of Analysis
This impact analysis is limited to the approximately 27-acre Project Area, comprising APNs 376-350-009 and 376-350-017, which will be permanently impacted to construct the proposed park and associated amenities. Offsite impacts are not addressed.

5.2 Special-Status Species
The literature review and database searches identified 48 special-status plant species. Of these, one species, paniculate tarplant, was observed within the Project Area; however, this species has a CRPR rank of 4.2 (limited distribution in California) and does not have the same protections as plant species with a rank of 1B; therefore, impacts to this species are not considered significant. However, it is recommended, if possible, to avoid impacting the species. In addition, one species, Coulter’s matilija poppy, was found to have a moderate potential to occur within the Project Area due to the presence of suitable habitat, however, there are no records of the species occurring within 5 miles of the Project. This species is an MSHCP covered species and a CRPR 4.2 species; thus, additional surveys will not be required. The remaining 46 species were determined to have a low potential to occur onsite or were presumed absent.

No additional sensitive plant species were observed during the biological surveys. No impacts to specialstatus plant or narrow endemic plant species are expected to occur as a result of the Proposed Project within the Project Area.

2022-252.03
Of the 32 special-status wildlife species identified in the literature search, one bird species was present during the biological reconnaissance survey just north of the Project Area and within the 500-foot survey buffer: coastal California gnatcatcher (federally listed threatened species and CDFW SSC). Suitable sage scrub habitat for this sensitive bird species occurs within the Project Area. This species is covered under the MSHCP; no additional surveys or mitigation will be required. As the Project Area is not located within a Criteria Area nor within Public Quasi-Public (PQP) lands, there are no seasonal limitations for clearing of suitable gnatcatcher habitat within the Project Area. The Project will be required to conduct a preconstruction nesting bird survey prior to site disturbance, as described in Section 8.0 of this document, to avoid take of any nesting birds.

Two special status wildlife species were determined to have a high potential to occur within the Project Area: BUOW and northwestern San Diego pocket mouse. The San Diego pocket mouse is covered under the MSHCP; no additional surveys or mitigation will be required. The Project is located within a designated survey area under the MSHCP for BUOW and the biological reconnaissance survey and habitat assessment determined that suitable BUOW habitat was present in the BUOW Study Area. If BUOW are present within the Project Area, direct impacts in the form of ground disturbance, vegetation removal, habitat loss, and mortality and indirect impacts from construction noise and vibrations may occur. Protocol-level surveys for BUOW will need to occur within the Burrowing Owl Study Area to determine presence/absence of the species within and adjacent to the Project Area, as described in Section 8.0 of this document.

Seven special status wildlife species were determined to have moderate potential to occur within the Project Area. Crotch bumble bee has a moderate potential to occur onsite and is listed as a Candidate species under the California ESA. Additional surveys for this species will be required in order to determine presence/absence of the species within the Project Area, as described in Section 8.0 of this document. Five of the special status wildlife species with moderate potential to occur are covered by the MSHCP: Bell’s sage sparrow, loggerhead shrike, red-diamond rattlesnake, San Diego black-tailed jackrabbit, and southern California rufous-crowned sparrow. These five species are considered adequately conserved under the MSHCP; no additional surveys or mitigation will be required. California glossy snake has a moderate potential to occur onsite and is a CDFW SSC. Direct impacts in the form of ground disturbance, vegetation removal, habitat loss, and mortality and indirect impacts from construction noise and vibrations may occur to the species. However, if this species were to be present within the Project Area; they would likely occur in low numbers due to anthropogenic disturbances and lack of connectivity on the Project and Project-related impacts would not contribute to the overall decline of populations of this species. Therefore, no impacts to California glossy snake are anticipated to result from this Project.

The remaining 22 special status wildlife species analyzed were determined to have a low potential to occur or are presumed absent due to the lack of suitable habitat occurring within the Project Area; thus, these species are not expected to occur within the Project Area and impacts to these species are not anticipated as a result of the Proposed Project.

The large eucalyptus trees and other ornamental trees located within or near the Project Area could provide nesting habitat for nesting birds and raptors protected by the MBTA and California Fish and Game Code. Ground-disturbing construction activities could directly affect nesting birds and other birds protected by the MBTA and their nests through habitat removal within the Project Area, and indirectly 888

through increased noise, vibrations, and increased human activity if any tree or vegetation removal needs to occur during the bird breeding season (typically January 15 through August 31). Impacts to sensitive bird species and/or nesting birds would be less than significant with the implementation of preconstruction surveys for nesting birds as described in Section 8.0 of this document.

5.3 Sensitive Natural Communities
No sensitive natural communities were observed within the Project Area or surrounding 500-foot survey buffer. No impacts to sensitive natural communities are anticipated to result from the Proposed Project.

5.4 State or Federally Protected Wetlands and Waters of the U.S.

As discussed in Section 4.5 of this document, the NWI identified one drainage within the Project Area and a desktop review of aerial imagery by ECORP identified another two potential drainage features within the Project Area. A formal Aquatic Resources Delineation was not conducted by ECORP as part of this Biological Technical Report. A formal delineation is recommended as further detailed in Section 8.0 of this document.

5.5 Wildlife Corridors and Nursery Sites
The Project likely provides local wildlife movement opportunities because it consists of open land and there are undeveloped parcels of land to the north and south of the Project Area. A large open space area occurs north of the Project Area; however, the Project Area is unlikely to function as a wildlife corridor for this open space habitat because no large open space habitats occur directly south, east, or west of the Project Area. No migratory wildlife corridors or native wildlife nursery sites were identified within the Project Area. No impacts to these resources are expected to occur within the Project Area.

5.6 Habitat Conservation Plans and Natural Community Conservation Plans
The Project is located within the planning area for the Western Riverside MSHCP. The Project is not located within any Conservation Areas. An MSHCP Consistency Analysis is included in Section 6.0, below.

6.0 MSHCP CONSISTENCY ANALYSIS

6.1 Introduction
The purpose of this Consistency Analysis is to summarize the biological data for the Proposed Project and to document the Proposed Project’s consistency with the goals and objectives of the MSHCP.

Please refer to Section 1.2 of this document for a Project description. This Consistency Analysis is limited to the approximately 27-acre Project Area composed of the two parcels identified above.

6.1.2 Covered Roads
The Project proposes to widen the following existing streets that surround the two parcels on-site: La Estrella Street, Susan Drive, and Wildomar Trail. The RCA MSHCP Information Map identifies Wildomar Trail as a Covered Road (Secondary) [RCA 2023a]. These offsite roadway improvements were not assessed as part of this Consistency Analysis.

6.1.3 General Setting
The Project is surrounded by a mix of developed and undeveloped land, with residential development and an elementary school to the south and east, undeveloped parcels to the north, and low-density rural residences to the west.

6.2 Reserve Assembly Analysis
The Project is located in the Elsinore Area Plan but not within any Area Plan Subunits with specific target conservation acreages and goals, planning species, biological issues and considerations, or criteria. The Project is not located within any Criteria Cells. The nearest Criteria Cell is 5350 located approximately

0.25 mile north of the northeastern boundary of the Project. The Project is not located within any Linkage that connects Core Areas nor does it function as a Core Area itself.

The entire Project Area lies within the MSHCP Burrowing Owl Survey Area (RCA 2023a). The Project is within the Menifee Habitat Management Unit. The Project Area is not within a Criteria Area Species Survey Area or a Cell Group.

The Proposed Project will be able to contribute to the overall MSHCP Reserve Assembly goals. The Proposed Project would not result in impeding the functionality of the Reserve features that are the focus of the Menifee Habitat Management Unit or the Elsinore Area Plan.

6.2.1 Public Quasi-Public Lands
The Proposed Project is not located within PQP Conserved Lands (RCA 2023a). The nearest PQP Conserved Lands occur approximately 0.2 mile northeast of the Project Area. Furthermore, the Project is not located in an area designated as Rural/Mountainous in the MSHCP Area, American Indian Lands, Lake, Pre-existing Conservation Agreements, or San Jacinto Wildlife Area Additional Acquisitions. Therefore, the Proposed Project would not have impacts on PQP-designated lands.

6.3 Vegetation Mapping and Species Compendia
Vegetation communities within the Project Area were mapped as part of the biological reconnaissance survey conducted by ECORP, as depicted in Figure 4. Please refer to Section 4.2.2 of this report for descriptions of vegetation communities onsite. Plants and wildlife observed within and adjacent to the 890

6.4 Protection of Species Associated with Riparian/Riverine Areas and Vernal Pools (Section 6.1.2)

6.4.1 Riparian/Riverine
In accordance with Section 6.1.2 of the MSHCP, ECORP performed a habitat assessment for riparian and riverine communities. The MSHCP defines Riparian and Riverine resources as “…areas dominated by trees, shrubs, persistent emergent plants, or emergent mosses and lichens which occur close to or are dependent upon nearby freshwater, or areas with freshwater flowing during all or a portion of the year” (RCTLMA 2023).

According to the RCA MSHCP Consistency Analysis Report Template, a riverine feature includes:
“any feature that is natural in origin as well as past natural features that have been heavily modified and/or redirected and can include features indirectly created through man-made manipulation of the landscape, including channelization of a historic riverine feature. If these features connect to nearby downstream resources that are either existing or described conservation lands, they would be considered riverine” (RCA 2023b).

Both vegetated (riparian) and unvegetated (riverine) drainages may be considered MSHCP resources.

6.4.1.1 Methods
Literature Review
Hydrology, soil, and USFWS NWI data were reviewed prior to the habitat assessment. In addition, Google Earth™ aerial imagery was reviewed to locate potential additional riparian/riverine areas within the Project Area.

Habitat Assessment
ECORP biologists visually surveyed the potential riparian/riverine areas of the Project Area. Where riparian/riverine habitat was present, the extent was verified if it had been previously mapped and new areas were mapped using a post-processing-capable GPS device. The extent of riparian habitat was based on the canopy of the riparian community, to the limits of the dripline, within or directly adjacent to the streambed that is likely deriving benefit from the hydrology of the streambed.

6.4.1.2 Existing Conditions and Results
The riparian/riverine habitat assessment was conducted for the Project Area by ECORP biologists Verity Richardson and Carley Adams on May 30, 2023.

The NWI identified one drainage feature occurring within the Project Area, which flows into the Project Area from the north and exits near the southwestern corner (Figure 6). The habitat assessment confirmed 891

that this drainage feature contains MSHCP riverine resources due to the presence of a bed and bank and its connection to downstream drainage features (Figure 7). This feature does not contain MSHCP riparian resources due to the lack of riparian vegetation.

Based on the desktop review of topographic mapping and historic and recent aerial imagery coupled with the on-site habitat assessment, two additional MSHCP riparian/riverine features occur within the Project Area. One drainage feature occurs near the southern boundary of the Project Area, beginning at the terminus of La Estrella Street where runoff from the street flows into the Project Area and continues in a southwestward direction (Figure 7); this feature contains both MSHCP riverine and riparian habitat based on the presence of a bed and bank, its connection to downstream drainage features, and the presence of riparian vegetation located within or directly adjacent to the drainage feature.

The third drainage feature occurs within the northeastern portion of the Project Area, flowing in a north to south direction into a culvert located along the perimeter of the Project Area boundary, north of the elementary school (Figure 7). This feature contains MSHCP riverine resources due to the presence of a bed and bank and its connection to downstream drainage features; this feature does not contain MSHCP riparian resources due to the lack of riparian vegetation.

The NRCS Web Soil Survey (2023) identified seven soil types within the Project Area, as described in Section 4.2.1 of this document. All of the identified soils are well-drained sandy loam soils. None are characterized as hydric, alkaline, or saline. The MSHCP riparian/riverine resources onsite may provide certain physical or chemical functions; however, their functionality is limited by their ephemeral nature, the presence of well-draining soils that prevent onsite retention or ponding, and by the routine habitat disturbance that occurs in some areas for weed/fire abatement. Functions may include nutrient and toxicant trapping, pollutant filtration, and flood flow attenuation.

The two MSHCP riverine features that flow within the Project Area from the north occur within both native California buckwheat scrub and non-native upland mustards vegetation communities. The areas containing non-native upland mustard vegetation contain low-quality habitat because they are disturbed in nature due to annual vegetation management consistent with weed/fire abatement activities. The areas of MSHCP riverine resources within California buckwheat scrub are characterized as moderate to high quality habitat due to the relative lack to disturbance; however, some areas are impacted by trash, offleash dogs, and dirt roads used by off-highway vehicles. The MSHCP riparian resource located within the Project Area contains low- to moderate-quality riparian habitat due to the abundance of non-native saltcedar that dominates the vegetation community within this area of the Project Area.

The MSHCP riparian/riverine resources within the Project Area provide some biological functions due to the presence of native habitat in some areas; however, low-quality, disturbed habitat dominated by nonnative vegetation is also present on-site. Furthermore, the MSHCP riparian/riverine resources do not support or provide habitat for MSHCP Section 6.1.2 species, including amphibians, riparian birds, fairy shrimp, fish, or sensitive plants, as detailed in the following sections of this document. 892

6.4.1.3 Impacts and Mitigation
The Project proposes to impact MSHCP riparian/riverine resources located within the Project Area. A Determination of Biologically Equivalent or Superior Preservation will be required to address proposed impacts to these resources. Mitigation may include on-site habitat restoration, off-site habitat restoration, the purchase of mitigation credits from an approved mitigation bank, or a combination thereof.

6.4.2 Vernal Pools and Fairy Shrimp
In accordance with Section 6.1.2 of the MSHCP, a habitat assessment was conducted for vernal pools and fairy shrimp species on May 30, 2023 for the Proposed Project.

6.4.2.1 Vernal Pools
The MSHCP defines vernal pools as:
“…seasonal wetlands that occur in depression areas that have wetlands indicators of all three parameters (soils, vegetation and hydrology) during the wetter portion of the growing season but normally lack wetlands indicators of hydrology and/or vegetation during the drier portion of the growing season. Obligate hydrophytes and facultative wetlands plant species are normally dominant during the wetter portion of the growing season, while upland species (annuals) may be dominant during the drier portion of the growing season. The determination that an area exhibits vernal pool characteristics, and the definition of the watershed supporting vernal pool hydrology, must be made on a case-by-case basis. Such determinations should consider the length of the time the area exhibits upland and wetland characteristics and the manner in which the area fits into the overall ecological system as a wetland. Evidence concerning the persistence of an area's wetness can be obtained from its history, vegetation, soils, and drainage characteristics, uses to which it has been subjected, and weather and hydrologic records (RCTLMA 2023).” Vernal pools are seasonal wetlands that alternate between periods of inundation and desiccation on an annual basis, corresponding to California’s Mediterranean climate of cool, wet winters and warm, dry summers. Distinct phases in this annual cycle include a wetting phase, an aquatic or inundation phase, a waterlogged-terrestrial phase, and a drought phase (Keeley and Zedler 1998). Keeley and Zedler (1998) define vernal pools as “precipitation-filled seasonal wetlands inundated during periods when temperature is sufficient for plant growth, followed by a brief waterlogged-terrestrial stage and culminating in extreme desiccating soil conditions of extended duration.”
California vernal pools host unique communities of plants and animals that have adapted to vernal pool conditions over a long geological timeframe. Vernal pools provide fishless breeding habitat for numerous invertebrates, aquatic insects, and amphibians during the aquatic phase (Zedler 1987). Western spadefoot toads utilize vernal pools for reproductive purposes and as a food source. As stated in Zedler’s report:
“…because of the brief periods of high productivity of the aquatic and amphibious plants and animals, the vernal pools probably also are a significant source of forage and prey” (Zedler 1987). Snakes may be attracted by the abundance of amphibians to prey upon, and mammals may utilize inundated pools as a source of water. Wading birds and waterfowl are attracted to the pools for food and as migratory 894

stopovers and are probably a major means by which plant propagules too large for wind dispersal are carried long distances (Zedler 1987). The desiccating soil conditions present during the summer months prevent the establishment of plant species typical of more perennial wetland ecosystems. The growth period of vernal pool plant species typically begins during the wetting or inundation phases. As pools begin to draw down, flowering is initiated for the majority of vernal pool plants. The drawdown process often creates ring-shaped stratification of plant species adapted to drier or wetter conditions around the perimeter of the shrinking inundation zone. Invasive plants such as Italian rye grass (Festuca perennis) and wild oat (Avena barbata and A. fatua) also follow the receding water, often crowding out the native vernal pool plant species.

6.4.2.2 Fairy Shrimp
Riverside Fairy Shrimp (Streptocephalus woottoni)
According to the USFWS 5-Year Review, Riverside fairy shrimp was first described in 1985 using specimens collected in Murrieta, California (USFWS 2008). This small crustacean is in the Order Anostraca and is distinguished from other fairy shrimp species due to the shape of their second antennae (males). Riverside fairy shrimp typically occur in vernal pools and other basins that hold water for sufficient periods (i.e., 7 to 8 weeks) to allow for completion of its lifecycle. Riverside fairy shrimp typically occur in vernal pools with depths greater than 12 inches (30 centimeters) and consume algae, bacteria, protozoa, rotifers, and particulate organic matter. Riverside fairy shrimp would not be able to persist in perennial bodies of water because they have evolved to require habitat that dries completely during the summer months, as well as having temperature constraints that cue hatching of cysts during the wet season. Once rainfall fills a vernal pool, cyst hatching, maturity, and reproduction occur within 7 to 8 weeks, and during some years hatch later in the season if late rains occur; typically, Riverside fairy shrimp are observed from January through March. Cysts (eggs) are typically deposited in the water column by females and sink to the bottom of the vernal pool, or if still within the brood sac of the female, will later fall to the floor of the basin when the female dies. Cysts can withstand temperature extremes and prolonged dry periods and not all cysts hatch during each inundation of a vernal pool, thereby producing a cyst bank. This cyst bank is one of the factors contributing to the long-term survival of Riverside fairy shrimp (USFWS 2008).

Vernal Pool Fairy Shrimp (Branchinecta lynchi)
The vernal pool fairy shrimp are endemic to California and southern Oregon and have the widest geographic range of the federally listed vernal pool crustaceans. They are genetically distinct from other Branchinecta species, distinguished by the morphology of the male’s second antenna and the female’s third thoracic segment (Belk and Fugate 2000). As with Riverside fairy shrimp, the vernal pool fairy shrimp has an ephemeral life cycle that relies on winter rains to fill pools for sufficient periods of time. Vernal pool fairy shrimp mostly occur in vernal pools and require cool water with temperatures below 50 degrees Fahrenheit for cysts to hatch (Eriksen and Belk 1999; Helm 1998). Vernal pool fairy shrimp are typically associated with smaller, shallow pools (6 inches deep) with relatively short inundation periods (Helm 1998). Their time to reach maturity and reproduction is temperature dependent, ranging from 18 to 147 days, with a mean of 40 days (Helm 1998).

Santa Rosa Plateau Fairy Shrimp (Linderiella santarosae) The Santa Rosa Plateau fairy shrimp is endemic to southern California and has an extremely restricted range. It is only known to occur in a few vernal pools on the Santa Rosa Plateau, which are characterized as southern basalt flow vernal pools that contain cool clear to milky waters (Eriksen and Belk 1999; Thiéry and Fugate 1994). The specific microhabitat used by Santa Rosa Plateau fairy shrimp is only known to occur on the Santa Rosa Plateau, and as such, it is unlikely Santa Rosa Plateau fairy shrimp occur outside this range (Keeler-Wolf et al. 1998).

6.4.2.3 Methods
Literature Review
ECORP performed a literature search prior to the habitat assessments to determine if any fairy shrimp species observations were documented in the Project vicinity. ECORP conducted a review of the (CDFW 2023a), NRCS Web Soil Survey (2023), NWI (USFWS 2023c), and RCA MSHCP Information Map (RCA 2023a) to determine if listed fairy shrimp species are known to occur within the Project Area or vicinity (within 5 miles) prior to the habitat assessment. ECORP performed a review of the USFWS IPaC (USFWS 2023a) to determine if USFWS-designated Critical Habitat is present within the Project Area. Google Earth™ historic aerial imagery was reviewed to locate any wetted depressions that may have the potential to support listed fairy shrimp or could qualify as a vernal pool within the Project Area.

Habitat Assessment
Following completion of the literature review, ECORP biologists Verity Richardson and Carley Adams conducted a habitat assessment survey to evaluate potential vernal pool and branchiopod habitat within the Project Area. The biologists walked the Project Area and areas of the 500-foot surrounding buffer where accessible in search of features that could provide listed branchiopod habitat and/or qualify as vernal pools. Potential habitat for federally listed large branchiopods, per USFWS Guidelines, is defined as any seasonal inundated depression that ponds water at a sufficient depth and duration for a listed large branchiopod to complete its life cycle (USFWS 2017). The presence of water marks, algae mats, drift lines, hydrophytic vegetation (i.e., water-loving plants), slope, contributing watershed, maximum potential ponding depth, and aquatic arthropod (i.e., crustacean and insect) exoskeletons are helpful indicators for evidence of ponding depth and duration. Habitats with swiftly flowing water (e.g., creeks, streams, ephemeral drainages) or semi-permanently to permanently inundated areas that support population of predators (e.g., bullfrogs, fish, crayfish) are generally not considered suitable habitat for listed large branchiopods.

6.4.2.4 Existing Conditions and Results
Literature Review
The review of the CNDDB documented six regional listed fairy shrimp species occurrences within 5 miles of the Project Area. The IPaC review identified no USFWS-designated Critical Habitat within or adjacent to the Project Area.

Riverside Fairy Shrimp
Riverside fairy shrimp is federally listed as Endangered and is an MSHCP Covered Species. There are four CNDDB occurrences within 5 miles of the Project Area. The nearest occurrence (#8) is located approximately 0.9 mile east of the Project Area within the Clayton Ranch mitigation site (FKA Schleuniger Pool). Occurrence #19 is located approximately 1.4 miles southeast of the Project Area, known as the Clayton Ranch site; the site was developed in 2003 and the species is now extirpated for this occurrence.

Occurrence #39 is located approximately 1.0 mile southeast of the Project Area and was recorded in 2009; this occurrence documents the species onsite, including gravid females, from vouchers taken in 2008 and 2009. Occurrence #11 is located within the Australia Pool mitigation site within the Lake Elsinore Back Basin, approximately 4.8 miles northwest of the Project Area.

Vernal Pool Fairy Shrimp
Vernal pool fairy shrimp is federally listed as Threatened and is an MSHCP Covered Species. There is one CNDDB occurrence within 5 miles of the Project Area, located within the Santa Rosa Plateau Ecological Reserve, approximately 5.0 miles south of the Project Area (Occurrence #641).

Santa Rosa Plateau Fairy Shrimp
Santa Rosa Plateau fairy shrimp is an MSHCP Covered Species. There is one CNDDB occurrence within 5 miles of the Project Area, located within the Santa Rosa Plateau Ecological Reserve, approximately

5.0 miles south of the Project Area (Occurrence #2).

Habitat Assessment
The vernal pool and fairy shrimp habitat assessment was conducted on May 30, 2023 by ECORP biologists Verity Richardson and Carley Adams. The biologists observed no features that could provide listed branchiopod habitat and/or qualify as vernal pools within the Project Area.

6.4.2.5 Impacts and Mitigation
The Project Area lacks suitable fairy shrimp and/or vernal pool habitat; therefore, impacts to these resources are not expected to occur due to implementation of the Proposed Project. Mitigation is not required for fairy shrimp or vernal pool habitat.

6.4.3 Riparian Birds
In accordance with Section 6.1.2 of the MSHCP, Protection of Species Associated with Riparian/Riverine Areas and Vernal Pools, ECORP assessed areas potentially supporting riparian bird populations during a habitat assessment for special-status riparian bird species conducted on May 30, 2023. 897

6.4.3.1 Methods
Literature Review
ECORP performed a literature search prior to the habitat assessment to determine if any special-status bird species observations were documented in the Project vicinity. Biologists performed a review of the CNDDB (CDFW 2023a) to determine the special-status bird species that have been documented within 5 miles of the Project Area. ECORP performed a review of the USFWS IPaC (USFWS 2023a) to determine if USFWS-designated Critical Habitat is present on or within the Project vicinity. The literature search results were reviewed prior to the habitat assessment in order to identify the locations of previously documented special-status species. The CNDDB results were then mapped on aerial background for surveyor reference in the field and to aid in data analysis.

Habitat Assessment
Following completion of the literature review, ECORP biologists experienced with special-status riparian bird species habitat, identification, behavior, sign, and vocalizations conducted a habitat assessment. The biologists conducted the assessment by walking throughout the entire Project Area and 500-foot buffer where accessible to characterize and map the suitability of habitat for special-status riparian bird species.

The biologists determined habitat suitability based on the natural history, habitat requirements, and the currently documented range boundaries of special-status bird species. Photographs were taken during the assessment to provide visual representation of the various vegetation communities within the Project Area.

6.4.3.2 Existing Conditions and Results
Literature Review
The review of the CNDDB yielded four recent records (within the last 20 years) of special-status riparian bird species occurrences within 5 miles of the Project Area. The IPaC identified no USFWS-designated Critical Habitat within or adjacent to the Project Area. Documented occurrences for special-status riparian bird species are discussed in greater detail below.

Western Yellow-Billed Cuckoo (Coccyzus americanus)
The western Distinct Population Segment (DPS) of the yellow-billed cuckoo (YBCU) is migratory and arrives from its wintering grounds in South America during June and departs from California during September (Small 1994). Breeding activity for the western DPS peaks in July (Halterman et al. 2016). The YBCU is federally listed as threatened, state listed as endangered, a USFWS Bird of Conservation Concern, and a MSHCP Covered Species. Federal Critical Habitat for YBCU was proposed in 2014 (USFWS 2014), revised in 2020 (USFWS 2020), and finalized in 2021 (USFWS 2021). The Project Area is not located within Critical Habitat for the YBCU (USFWS 2023b). No CNDDB records occur within 5 miles of the Project Area for this species.

Least Bell’s Vireo (Vireo bellii pusillus)
The least Bell’s vireo (LBVI) is endemic to California and Baja California, Mexico. Least Bell’s vireos are migratory species in which the males arrive in California between late March to April and establish breeding territories, and the females arrive shortly thereafter (USFWS 1998). The least Bell's vireo usually returns to the wintering grounds between August to September. The LBVI is federally listed as endangered, state listed as endangered, and a MSHCP Covered Species. Critical Habitat for LBVI was designated on March 4, 1994 (USFWS 1994). The Project Area is not located within or adjacent to Critical Habitat for the LBVI (USFWS 2023b). Four recent (within the last 20 years) CNDDB occurrences were recorded within 5 miles of the Project Area (CDFW 2023a).

Southwestern Willow Flycatcher (Empidonax traillii extimus) The southwestern willow flycatcher (SWWF) is a neotropical migratory bird that winters in Central America and migrates to the U.S. and Canada to breed during summer. Their breeding habitat currently ranges from southern California, through Arizona, New Mexico, southern Nevada, southern Utah, and southwestern Colorado. Overall, individuals only spend three to four months paired with a mate during the breeding season. Individuals then begin their southward migration in early August through September. During their migration, individuals will stop at food-rich stopover locations in order to replenish their energy reserves (USFWS 2013). The SWWF is federally listed as endangered, state listed as endangered, and an MSHCP Covered Species. Critical Habitat for this species was originally designated in 1997, revised in 2005, and revised again in 2013 (USFWS 2013). The Project Area is not located within or adjacent to designated Critical Habitat for the SWWF (USFWS 2023b). No CNDDB occurrences were recorded within 5 miles of the Project Area for this species.

Habitat Assessment
ECORP biologists Verity Richardson and Carley Adams conducted the habitat assessment on May 30, 2023. Habitat suitability for sensitive riparian bird species within the Project Area is discussed in further detail below.

Western Yellow-Billed Cuckoo
Habitat requirements for the YBCU includes fairly large trees and dense vegetation, and the species is typically associated with riparian woodlands along perennial rivers and streams at elevations below 6,600 feet above mean sea level (amsl). The most commonly inhabited communities include species such as Fremont cottonwood and willow (Salix spp.); however, saltcedar, mesquite (Prosopsis sp.), and other riparian tree communities may also be used. Approximately 2 to 3 weeks prior to breeding, YBCU may occupy upland vegetation including pinyon (Pinus spp.), oak (Quercus spp.), juniper (Juniperus spp.), and manzanita (Arctostaphylos spp.) (Hughes 2020). Nesting habitat typically includes large contiguous patches of multilayered riparian habitat with dense understory foliage. YBCU feed primarily on large insects such as caterpillars, katydids, cicadas, grasshoppers, and crickets. Cuckoo populations fluctuate greatly with food availability and increase dramatically in years of highest insect abundance (Heath and Wilkin 1970).

Ronald Reagan Park Project
38 July 2023
2022-252.03
ECORP determined that suitable breeding and foraging habitat for YBCU was not present within the Project Area. Based on the habitat requirements of YBCU, no potential nesting YBCU habitat was found within the Project Area. While small patches of willows, mulefat, and cottonwoods are present, the Project Area lacks the complex old growth structure that the YBCU need for foraging and breeding. Consequently, YBCU individuals are not expected to occur on or near the Project Area.

Least Bell’s Vireo
The LBVI is dependent upon riparian habitat during the breeding season and prefers willow-dominated woodland or scrub that typically exists along streams and rivers (Franzreb 1989). Other habitat types used by this species include mulefat scrub, mixed oak/willow woodland, mesquite woodland, and elderberry (Sambucus spp.) scrub. In southern California, least Bell’s vireos typically occur below 2,000 feet amsl (Zeiner et al. 1990). The species has been documented at extreme elevations in Death Valley (i.e., -175 feet) and in the City of Bishop in Inyo County (i.e., 4,100 feet), although it is uncommon above 4,000 feet amsl in coastal southern California (Grinnell and Miller 1944; Brown 1993). Habitat characteristics that appear to be essential for least Bell’s vireo occupation include dense cover from three to six feet in height for nesting and foraging, and a stratified canopy providing both foraging habitat and song perches for territorial advertisement.

ECORP determined that suitable breeding and foraging habitat for LBVI was not present within the Project Area. Based on the habitat requirements of LBVI, no potential nesting habitat was found within the Project Area. While small patches of willows, mulefat, and cottonwoods are present, they are not abundant or continuous enough to provide suitable foraging and breeding habitat for the species. Consequently, LBVI individuals are not expected to occur on or near the Project Area.

Southwestern Willow Flycatcher
Habitat requirements for the SWWF includes dense riparian vegetation near permanent or semipermanent sources of water or saturated soil, such as cottonwood, willow, and salt cedar vegetation communities along rivers and streams below 8,500 feet amsl. SWWF typically breed within dense tree or shrubby riparian vegetation that is equal to or greater than 10 feet tall (Allison et al. 2003). Additional migration habitat occurs along major drainages in the southwest, and may include riparian habitats without an understory, non-riparian areas with high food concentrations, or within linear patches that may typically be considered too small or short (USFWS 2013).

ECORP determined that suitable nesting and foraging habitat for the SWWF was not present within the Project Area. While small patches of willows, mulefat, and cottonwoods are present, they are not abundant or continuous enough to provide suitable foraging and breeding habitat for the species.

Consequently, SWWF individuals are not expected to occur on or near the Project Area.

6.4.3.3 Impacts and Mitigation
Impacts are not expected to occur to YBCU, LBVI, or SWWF due to implementation of the Proposed Project. Therefore, mitigation is not required for YBCU, LBVI, or SWWF. 900

6.4.4 Other Section 6.1.2 Species
ECORP assessed other Section 6.1.2 plant and wildlife species for their potential to occur which are included in Appendices D and E of this document. Please refer to Section 4.2.5 for a discussion of sensitive species with potential to occur onsite.

No impacts are expected to Section 6.1.2 plant and wildlife species provided in Appendices D and E.

Comprehensive plant and wildlife species compendia documenting plant and wildlife species observed within the proposed Project Area are included as Appendices B and C, respectively.

6.5 Protection of Narrow Endemic Plant Species (Section 6.1.3) The RCA MSHCP Information Map was reviewed to determine whether the Proposed Project is located within a Narrow Endemic Plant Species Survey Area (NEPSSA; RCA 2023a) in accordance with Section 6.1.3 of the MSHCP. The Proposed Project is not located within an NEPSSA, and no further discussion is provided in this document.

6.6 Additional Survey Needs and Procedures (Section 6.3.2)

6.6.1 Criteria Area Plant Species
The proposed Project Area is not located within a mapped survey area for MSHCP Criteria Area plant species (RCA 2023a); therefore, no further discussion is provided in this document.

6.6.2 Amphibians
The proposed Project Area is not located within a mapped survey area for MSHCP amphibian species (RCA 2023a); therefore, no further discussion is provided in this document.

6.6.3 Burrowing Owl
The Proposed Project is located within the MSHCP Survey Area for BUOW (RCA 2023a; Figure 3). A BUOW habitat assessment was conducted within the Burrowing Owl Study Area on May 30, 2023.

6.6.3.1 Methods
Literature Review
ECORP performed a literature search prior to the habitat assessment to determine if any burrowing owl observations were documented in the Project vicinity. Biologists performed a review of the CNDDB (CDFW 2023a) to determine the burrowing owl occurrences that have been documented within 5 miles of the Project Area. The literature search results were reviewed prior to the habitat assessment in order to identify the locations of previously documented species occurrences. The CNDDB results were then mapped on aerial background for surveyor reference in the field and to aid in data analysis. 901

Habitat Assessment
Following completion of the literature review, ECORP conducted a BUOW habitat assessment concurrently with the biological reconnaissance survey to determine the presence of suitable habitat. Biologists walked the Project Area and a 500-foot buffer (Figure 3) to identify the presence of owl habitat, scanning for suitable habitat using binoculars in areas that were inaccessible by foot. All encountered burrows were marked during the habitat assessment and focused burrow survey.

Photographs were taken during the assessment to provide visual representation of the various vegetation communities within the Burrowing Owl Study Area.

6.6.3.2 Existing Conditions and Results
Literature Review
The review of the CNDDB yielded seven records of burrowing owl occurrences within 5 miles of the Project area, all of which were documented between 2005 and 2008. The nearest occurrence to the Project was documented in 2007 and was located 3.0 miles northwest of the Project (Occurrence #974).

Habitat Assessment
ECORP biologists Verity Richardson and Carley Adams conducted the BUOW habitat assessment and focused burrow survey concurrently with the biological reconnaissance survey on May 30, 2023 within the Burrowing Owl Study Area. Weather conditions during the assessment are summarized in Table 1.

The assessment determined that the Project Area included suitable habitat for BUOW, primarily within the southern portions of the Project Area consisting of non-native forbs and grasses on level to gently rolling terrain, with an abundance of active California ground squirrel burrows, a few of which could be suitable for BUOW. ECORP recorded potential burrows within the Burrowing Owl Study Area (Figure 3). Protocollevel burrowing owl surveys were not performed by ECORP following the habitat assessment and focused burrow survey.

6.6.3.3 Impacts and Mitigation
Direct impacts to habitats that support foraging and nesting habitat for breeding and/or overwintering BUOW habitat may occur as a result of the Project. Other direct impacts that may occur include injury or mortality during construction activities, injury by vehicles and equipment using the roadway, and/or loss of nest or nest occupants if habitat is cleared during the breeding season. Indirect impacts to BUOW foraging, nesting, migratory, or overwintering activities may also occur as a result of Project construction in the form of increased human and vehicular activity, noise, dust, ground vibrations, nighttime lighting, and habitat degradation. These temporary changes in the existing environment during construction of the Project may result in altered adult bird behavior that could lead to lower fitness due to decreased foraging activities, loss of shelter or protective cover, or abandonment of young or a nest with eggs in it.

Potential direct and indirect impacts can be avoided or reduced with the implementation of appropriate avoidance and minimization measures.

2022-252.03
Suitable burrowing owl habitat exists within the Project Area. Therefore, protocol-level burrowing owl surveys will be required to be performed during the breeding season (March 1 through August 31) as required under Part 2B of the MSHCP Burrowing Owl Survey Instructions, consisting of four separate surveys conducted throughout the Project Area, and within the 500-foot buffer (Burrowing Owl Study Area; RCA 2006), where accessible, to determine if, when, and how the Study Area is being used by BUOW. Additionally, a preconstruction survey will be required within 30 days prior to site disturbance. It is typically recommended by CDFW that two preconstruction surveys take place: one within 14 to 30 days and the second within 24 hours of the start of ground-disturbing activities (including vegetation removal, clearing and grubbing, grading, etc.).

6.6.4 Mammals
The proposed Project Area is not located within a mapped survey area for MSHCP mammal species (RCA 2023a); therefore, no further discussion is provided in this document.

6.7 Information on Other Species

6.7.1 Delhi Sands Flower Loving Fly
The proposed Project Area is not located within an area with Delhi soils mapped within the MSHCP baseline data (RCA 2023a); no further discussion is provided in this document.

6.7.2 Coastal California Gnatcatcher
Coastal California gnatcatcher was heard calling within native scrub habitat located north of the Project Area, within the 500-foot survey buffer area. As the Project Area is not located within a Criteria Area nor within PQP lands, there are no seasonal limitations for clearing of suitable gnatcatcher habitat within the Project Area. The Project will be required to conduct a pre-construction nesting bird survey prior to site disturbance, as described in Section 8.0 of this document, to avoid take of any nesting birds.

6.7.3 Species Not Adequately Conserved
No MSHCP Table 9-3 species were observed within or adjacent to the Project Area during the May 2023 biological reconnaissance survey. All species listed in MSHCP Table 9-3 were determined to have a low potential or are presumed absent from the Project Area, based on a lack of suitable habitat/soils and/or the Project Area is located outside of the known elevational range or distribution for the species.

6.8 Guidelines Pertaining to the Urban/Wildlands Interface (Section 6.1.4) The proposed Project Area is not located adjacent to and does not have onsite connection to either existing conservation or land described for conservation. As defined in the MSHCP, Conservation Areas are approximately 500,000 acres composed of roughly 347,000 acres of PQP Lands and 153,000 acres of Additional Reserves Lands within western Riverside County. The Urban/Wildland Interface is defined as a zone (less than 100 feet) between a project site and the MSHCP Conservation Area. Avoidance measures must be implemented if a project is located adjacent to a Conservation Area. The nearest Conservation Area is located 0.25 mile north of the northeast corner of the Project Area, known as Iodine Springs (RCA 903

2023a). Thus, no further discussion of the guidelines pertaining to the Urban/Wildlands Interface is provided.

7.0 BEST MANAGEMENT PRACTICES
The Project shall comply with the Standard Best Management Practices (BMPs) of the MSHCP (Volume I, Appendix C), as follows:

1. A condition shall be placed on grading permits requiring a qualified biologist to conduct a training session for project personnel prior to grading. The training shall include a description of the species of concern and its habitats, the general provisions of the Endangered Species Act (Act) and the MSHCP, the need to adhere to the provisions of the Act and the MSHCP, the penalties associated with violating the provisions of the Act, the general measures that are being implemented to conserve the species of concern as they relate to the project, and the access routes to and project site boundaries within which the project activities must be accomplished.

2. Water pollution and erosion control plans shall be developed and implemented in accordance with RWQCB requirements.

3. The footprint of disturbance shall be minimized to the maximum extent feasible. Access to sites shall be via pre-existing access routes to the greatest extent possible.

4. The upstream and downstream limits of projects disturbance plus lateral limits of disturbance on either side of the stream shall be clearly defined and marked in the field and reviewed by the biologist prior to initiation of work.

5. Projects should be designed to avoid the placement of equipment and personnel within the stream channel or on sand and gravel bars, banks, and adjacent upland habitats used by target species of concern.

6. Projects that cannot be conducted without placing equipment or personnel in sensitive habitats should be timed to avoid the breeding season of riparian identified in MSHCP Global Species Objective No. 7.

7. When stream flows must be diverted, the diversions shall be conducted using sandbags or other methods requiring minimal instream impacts. Silt fencing of other sediment trapping materials shall be installed at the downstream end of construction activity to minimize the transport of sediments offsite. Settling ponds where sediment is collected shall be cleaned out in a manner that prevents the sediment from reentering the stream. Care shall be exercised when removing silt fences, as feasible, to prevent debris or sediment from returning to the stream.

8. Equipment storage, fueling, and staging areas shall be located on upland sites with minimal risks of direct drainage into riparian areas or other sensitive habitats. These designated areas shall be located in such a manner as to prevent any runoff from entering sensitive habitat. Necessary precautions shall be taken to prevent the release of cement or other toxic substances into surface waters. Project related spills of hazardous materials shall be reported to appropriate entities including but not limited to applicable jurisdictional city, [USFWS], and [California Department of 904
Biological Technical Report and Western Riverside County MSHCP Consistency Analysis ECORP Consulting, Inc.

Ronald Reagan Park Project
43 July 2023
2022-252.03
Fish and Game], RWQCB and shall be cleaned up immediately and contaminated soils removed to approved disposal areas.

9. Erodible fill material shall not be deposited into water courses. Brush, loose soils, or other similar debris material shall not be stockpiled within the stream channel or on its banks.

10. The qualified project biologist shall monitor construction activities for the duration of the project to ensure that practicable measures are being employed to avoid incidental disturbance of habitat and species of concern outside the project footprint.

11. The removal of native vegetation shall be avoided and minimized to the maximum extent practicable. Temporary impacts shall be returned to pre-existing contours and revegetated with appropriate native species.

12. Exotic species that prey upon or displace target species of concern should be permanently removed from the site to the extent feasible.

13. To avoid attracting predators of the species of concern, the project site shall be kept as clean of debris as possible. All food related trash items shall be enclosed in sealed containers and regularly removed from the site(s).

14. Construction employees shall strictly limit their activities, vehicles, equipment, and construction materials to the proposed project footprint and designated staging areas and routes of travel. The construction area(s) shall be the minimal area necessary to complete the project and shall be specified in the construction plans. Construction limits will be fenced with orange snow screen.

Exclusion fencing should be maintained until the completion of all construction activities.

Employees shall be instructed that their activities are restricted to the construction areas.

15. The Permittee shall have the right to access and inspect any sites of approved projects including any restoration/enhancement area for compliance with project approval conditions including these BMPs.

8.0 AVOIDANCE AND MINIMIZATION MEASURES
Avoidance and minimization measures for the Project are included below in order to satisfy federal, state, and local regulations.
 To the greatest extent practicable, ground-disturbing activities, including vegetation removal, shall be conducted outside of the nesting bird season (approximately September 1 through January 14) to avoid direct and indirect impacts to nesting birds. This will avoid violations of the Migratory Bird Treaty Act and California Fish and Game Code Sections 3503, 3503.5, and 3513. If seasonal avoidance cannot be implemented, it is recommended that ground-disturbing activities, including vegetation removal, be conducted outside of suitable habitat during the breeding season to the greatest extent possible. If Project-related activities cannot avoid the nesting bird season then preconstruction surveys, non-disturbance limit buffers, and biological monitoring during Project activities will be necessary to avoid impacts to nesting birds. 905

 Offsite roadway improvements along La Estrella Street, Susan Drive, and Wildomar Trail were not assessed as part of this Biological Technical Report and MSHCP Consistency Analysis. An analysis of impacts to potential biological resources within these offsite improvement areas is recommended.
 Due to the presence of suitable habitat, a focused survey for Crotch bumble bee, a California ESA Candidate species, is recommended in order to determine presence/absence of the species within the Project Area. If the species is observed within the Project Area, coordination with CDFW will be required.
 A formal Aquatic Resource Delineation is recommended in order to determine if the drainage features within the Project Area contain aquatic resources jurisdictional to the USACE, RWQCB, or CDFW, and to determine the acreage of MSHCP Riparian/Riverine resources present onsite.

Impacts to jurisdictional waters require mitigation through habitat creation, restoration, or enhancement as determined by consultation with the regulatory agencies during the permitting process. Any impacts to CDFW jurisdiction would require a Section 1602 SAA from CDFW. Any impacts to Waters of the U.S. would require a Section 404 permit from the USACE. Impacts to Waters of the U.S. or State would also require a 401 Certification or Waste Discharge Requirements from the San Diego RWQCB.
 A Determination of Biologically Equivalent or Superior Preservation is recommended to be prepared, in conjunction with the Aquatic Resource Delineation, to address proposed impacts to MSHCP Riparian/Riverine resources located within the Project Area. Impacts to MSHCP Riparian/Riverine resources will require mitigation to be approved by the Wildlife Agencies (CDFW and USFWS).
 Protocol-level surveys for burrowing owl are recommended in order to demonstrate consistency with the requirements of the MSHCP. Surveys are required to be performed during the breeding season (March 1 through August 31) as required under Part 2B of the MSHCP Burrowing Owl Survey Instructions, consisting of four separate surveys conducted throughout the Project Area, and within a 500-foot buffer surrounding the Project Area (RCTLMA 2006), where accessible, to determine if, when, and how the Study Area is being used by burrowing owl. Additionally, a preconstruction survey will be required within 30 days prior to site disturbance. Recommended mitigation measure language for the preconstruction survey is included below:

Preconstruction Survey for BUOW: A preconstruction survey for BUOW shall be conducted within the Project Area and adjacent areas within 30 days prior to the start of grounddisturbing activities. The surveys shall follow the methods described in the Western Riverside MSHCP Burrowing Owl Survey Instructions (RCTLMA 2006). If BUOW and/or suitable BUOW burrows with sign (e.g., whitewash, pellets, feathers, prey remains) are identified within the Project Area during the survey and impacts to those features are unavoidable, consultation with the RCA and CDFW will be required.
 A preconstruction survey for nesting birds is recommended prior to the commencement of ground-disturbing activities within the identified nesting bird season to avoid take of nesting birds. Recommended mitigation measure language is provided below:

Ronald Reagan Park Project
45 July 2023
2022-252.03
Preconstruction Survey for Nesting Birds: All ground-disturbing activities shall be conducted during the nonbreeding season for birds (approximately September 1 through January 14) to the greatest extent possible. This will avoid violations of the MBTA and California Fish and Game Code Sections 3503, 3503.5 and 3513. If activities with the potential to disrupt nesting birds are scheduled to occur during the bird breeding season (January 15 through August 31), a preconstruction survey for nesting birds shall be conducted by a qualified biologist who is experienced in the identification of avian species and conducting nesting bird surveys. The nesting survey shall include the Project Area and adjacent areas where Project activities have the potential to cause nest failure. The preconstruction survey shall be conducted no more than 3 days prior to the start of ground-disturbing activities within the bird breeding season. If no nesting birds are observed during the survey, site preparation and construction activities may begin. If nesting birds (including nesting raptors) are found to be present, avoidance or minimization measures shall be implemented to avoid potential Project-related impacts. Measures may include establishment of an avoidance buffer until nesting has been completed and periodic nest monitoring by the Project biologist until the juveniles have fledged and there has been no evidence of a second attempt at nesting.

The width of the avoidance buffer will be determined by the Project biologist. The monitoring biologist will monitor the nest(s) during construction and document any findings. Once nesting is deemed complete by the Project biologist, work may resume within the avoidance buffer area.

MANAGEMENT SUMMARY
PlaceWorks, Inc. retained ECORP Consulting, Inc. in 2023 to conduct an archaeological resources inventory for the Ronald Reagan Park Project in Riverside County, California. The Project proposes to construct a 27- acre park with parking spaces, driveways, bike trails, playgrounds, various outdoor fitness areas and a fire station.

The inventory included a records search, literature review, and field survey. Due to delayed response time to records search requests with the California Historical Resources Information System’s (CHRIS) Eastern Information Center (EIC), project specific records search results were not available at time of writing. To mitigate this gap of information, ECORP utilized results from its own previous projects within 0.5 mile of the Project Area. These results indicated that two previous cultural resources studies have been conducted within 0.5 mile of the Project Area. As a result of those studies, five cultural resources have previously been recorded within 0.5 mile of the Project Area: four are historic-period, associated with agriculture and buildings; and one is a pre-contact lithic debitage scatter.

The field survey did not yield any cultural resources. The results received from the EIC may alter the findings of the report and additional work may be required. Until the results from EIC are received, no recommendations can be provided at this time.

1.0 INTRODUCTION
PlaceWorks, Inc. retained ECORP Consulting, Inc. in 2023 to conduct an archaeological resources inventory for the Ronald Reagan Park Project in the City of Wildomar, Riverside County, California. A survey of the Proposed Project Area was required to identify potentially eligible cultural resources (i.e., archaeological sites and historic buildings, structures, and objects) that could be affected by the Project.

1.1 Project Location
The Project Area consists of approximately 27 acres of property located in the southeastern quarter of the northeastern quarter of Section 36 of Township 6 South, Range 4 West, San Bernardino Base and Meridian as depicted on the 1953 (photorevised 1979) Murrieta, California U.S. Geological Survey (USGS) 7.5- minute topographic quadrangle map (Figure 1). It is also known as Assessor’s Parcel Numbers 376-350-009 and 376-350-017. The Project Area is located north and west of Ronald Reagan Elementary School, north of La Estrella Street, east of Susan Drive, and west of Wildomar Trail in the City of Wildomar, Riverside County.

1.2 Project Description
The Proposed Project entails the construction of a 27-acre park with 221 parking spaces; five driveways (two along Wildomar Trail, one along La Estrella Street, and two along Susan Drive); and amenities, including bike trails, a bike plaza, a fitness plaza, a fire station, a splash pad, playgrounds, volleyball courts, gardens, a community green area, a community center, an amphitheater, shade structures, lookout points, trails, bridge crossings, interpretive signs, bioretention/biofiltration areas, and a connection to Ronald Reagan Elementary School. The 8,700-square-foot fire station will be constructed on the western side of the Project Area, with access via one of the driveways from Susan Drive. A shared parking lot with 39 spaces would wrap around the northern and eastern side of the building and would include sidewalks security fencing along the perimeter. The proposed fire station would include exterior lighting for emergencies and safety. The proposed 8,700-square-foot community center would be in the approximate center of the Project Area and would be accessed via the southern entrance and parking area. The southwestern side of the building would have a landscaped patio with interpretive signage. The northeastern side of the building would feature a stage for the amphitheater. The amphitheater would be located to the northeast of the community center and would be constructed of rock retaining walls.

1.3 Area of Potential Effects
The Area of Potential Effects (APE) consists of the horizontal and vertical limits of a project and includes the area within which significant impacts or adverse effects to Historical Resources or Historic Properties could occur as a result of the project. The APE is defined for projects subject to regulations implementing Section 106 (federal law and regulations). For projects subject to the California Environmental Quality Act (CEQA) review, the term Project Area is used rather than APE. The terms Project Area and APE are interchangeable for the purpose of this document.

The horizontal APE consists of all areas where activities associated with a project are proposed and, in the case of this Project, equals the Project Area subject to environmental review under the National Environmental Policy Act (NEPA) and CEQA. This includes areas proposed for construction, vegetation removal, and other elements in the official Project description. The horizontal APE is illustrated in Figure 1.

The vertical APE is described as the maximum depth below the surface to which excavations for project foundations and facilities will extend. Therefore, the vertical APE for this Project includes all subsurface areas where archaeological deposits could be affected. The subsurface vertical APE varies across the Project Area; however, this study assumes the depth of ground disturbance will not exceed 6 feet below the current surface. Therefore, a review of geologic and soils maps was necessary to determine the potential for buried archaeological sites that cannot be seen on the surface.

The vertical APE also is described as the maximum height of structures that could impact the physical integrity and integrity of setting of cultural resources, including districts and traditional cultural properties.

For this Project, the above-surface vertical APE is as high as 50 feet above the surface, which is the excepted height of the construction development described in Section 1.2.

1.3.1 National Environmental Policy Act
NEPA establishes national policy for the protection and enhancement of the environment. Part of the function of the federal government in protecting the environment is to “preserve important historic, cultural, and natural aspects of our national heritage.” Cultural resources need not be determined eligible for the National Register of Historic Places (NRHP) through the National Historic Preservation Act (NHPA) of 1966 (as amended) to receive consideration under NEPA. NEPA is implemented by regulations of the Council on Environmental Quality (40 Code of Federal Regulations [CFR] 1500-1508).

The definition of effects in the NEPA regulations includes adverse and beneficial effects on historic and cultural resources (40 CFR 1508.8). Therefore, the Environmental Consequences section of an Environmental Impact Statement [see 40 CFR 1502.16(f))] must analyze potential effects to historic or cultural resources that could result from the proposed action and each alternative. In considering whether an alternative may “significantly affect the quality of the human environment,” a federal agency must consider, among other things:
 Unique characteristics of the geographic area, such as proximity to historic or cultural resources (40 CFR 1508.27(b)(3)), and
 The degree to which the action may adversely affect districts, sites, highways, structures, or objects listed in or eligible for listing in the NRHP (40 CFR 1508.27(b)(8)).

Therefore, because historic properties are a subset of cultural resources, they are one aspect of the human environment defined by NEPA regulations.

1.3.2 National Historic Preservation Act
The federal law that covers cultural resources that could be affected by federal undertakings is the NHPA of 1966, as amended. Section 106 of the NHPA requires that federal agencies take into account the effects 952
Archaeological Resources Inventory Report
ECORP Consulting, Inc.

Ronald Reagan Park Project
4 July 2023
2022-252.03
of a federal undertaking on properties listed in or eligible for the NRHP. The agencies must afford the Advisory Council on Historic Preservation (ACHP) a reasonable opportunity to comment on the undertaking. A federal undertaking is defined in 36 CFR 800.16(y):
“A federal undertaking means a project, activity, or program funded in whole or in part under the direct or indirect jurisdiction of a federal agency, including those carried out by or on behalf of a federal agency; those carried out with Federal financial assistance; and those requiring a Federal permit, license, or approval.” The regulations that stipulate the procedures for complying with Section 106 are in 36 CFR 800. The Section 106 regulations require:
 definition of the APE;
 identification of cultural resources within the APE;
 evaluation of the identified resources in the APE using NRHP eligibility criteria;  determination of whether the effects of the undertaking or project on eligible resources will be adverse; and
 agreement on and implementation of efforts to resolve adverse effects, if necessary.

The federal agency must seek comment from the State Historic Preservation Officer (SHPO) and, in some cases, the ACHP, for its determinations of eligibility, effects, and proposed mitigation measures. Section 106 procedures for a specific project can be modified by negotiation of a Memorandum of Agreement or Programmatic Agreement between the federal agency, the SHPO, and, in some cases, the project proponent.

Effects to a cultural resource are potentially adverse if the lead federal agency, with the SHPO’s concurrence, determines the resource eligible for the NRHP, making it a Historic Property, and if application of the Criteria of Adverse Effects (36 CFR 800.5[a][2] et seq.) results in the conclusion that the effects will be adverse. The NRHP eligibility criteria, contained in 36 CFR 63, are as follows:

The quality of significance in American history, architecture, archaeology, and culture is present in districts, sites, buildings, structures, and objects of state and local importance that possess aspects of integrity of location, design, setting, materials, workmanship, feeling, association, and
A. that are associated with events that have made a significant contribution to the broad patterns of our history; or
B. that are associated with the lives of persons significant in our past; or C. that embody the distinctive characteristics of a type, period, or method of construction, or that represent the work of a master, or that possess high artistic values, or that represent a significant and distinguishable entity whose components may lack individual distinction; or
953

D. that have yielded, or may be likely to yield, information important in prehistory.

In addition, the resource must be at least 50 years old, barring exceptional circumstances (36 CFR 60.4).

Resources that are eligible for, or listed on, the NRHP are historic properties.

Regulations implementing Section 106 of the NHPA (36 CFR 800.5) require that the federal agency, in consultation with the SHPO, apply the Criteria of Adverse Effect to historic properties within the APE.

According to 36 CFR 800.5(a)(1):
“An adverse effect is found when an undertaking may alter, directly or indirectly, any of the characteristics of a historic property that qualify the property for inclusion in the National Register in a manner that would diminish the integrity of the property’s location, design, setting, materials, workmanship, feeling or association.”

1.3.3 California Environmental Quality Act
CEQA is the state law that applies to a project’s impacts on cultural resources. A project is an activity that may cause a direct or indirect physical change in the environment and that is undertaken or funded by a state or local agency, or requires a permit, license, or lease from a state or local agency. CEQA requires that impacts to Historical Resources be identified and, if the impacts will be significant, then apply mitigation measures to reduce the impacts.

A Historical Resource is a resource that 1) is listed in or has been determined eligible for listing in the California Register of Historical Resources (CRHR) by the State Historical Resources Commission, or has been determined historically significant by the CEQA lead agency because it meets the eligibility criteria for the CRHR, 2) is included in a local register of historical resources, as defined in Public Resources Code (PRC) 5020.1(k), or 3), and has been identified as significant in a historical resources survey, as defined in PRC 5024.1(g) (California Code of Regulations [CCR] Title 14, Section 15064.5(a)).

The eligibility criteria for the CRHR are as follows (CCR Title 14, Section 4852(b)):
(1) It is associated with events that have made a significant contribution to the broad patterns of local or regional history, or the cultural heritage of California or the United States; (2) It is associated with the lives of persons important to local, California, or national history; (3) It embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of a master or possesses high artistic values; or (4) It has yielded, or has the potential to yield, information important to the prehistory or history of the local area, California, or the nation.

In addition, the resource must retain integrity, which is evaluated with regard to the retention of location, design, setting, materials, workmanship, feeling, and association (CCR Title 14, Section 4852(c)). Resources that have been determined eligible for the NRHP are automatically eligible for the CRHR. 954
Archaeological Resources Inventory Report

2022-252.03
Impacts to a Historical Resource, as defined by CEQA (listed in an official historic inventory or survey or eligible for the CRHR), are significant if the resource is demolished or destroyed or if the characteristics that made the resource eligible are materially impaired (CCR Title 14, Section 15064.5(b)). Demolition or alteration of eligible buildings, structures, and features that they would no longer be eligible would result in a significant impact. Whole or partial destruction of eligible archaeological sites would result in a significant impact. In addition to impacts from construction resulting in destruction or physical alteration of an eligible resource, impacts to the integrity of setting (sometimes termed visual impacts) of physical features in the Project Area could also result in significant impacts.

Tribal Cultural Resources (TCRs) are defined in Section 21074 of the California PRC as sites, features, places, cultural landscapes (geographically defined in terms of the size and scope), sacred places, and objects with cultural value to a California Native American tribe that are either included in or determined to be eligible for inclusion in the CRHR, or are included in a local register of historical resources as defined in subdivision (k) of Section 5020.1, or are a resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision (c) of Section 5024.1. Section 1(b)(4) of Assembly Bill (AB) 52 established that only California Native American tribes, as defined in Section 21073 of the California PRC, are experts in the identification of TCRs and impacts thereto. Because ECORP does not meet the definition of a California Native American tribe, it only addresses information in this report for which it is qualified to identify and evaluate, and that which is needed to inform the cultural resources section of CEQA documents. This report, therefore, does not identify or evaluate TCRs. Should California Native American tribes ascribe additional importance to or interpretation of archaeological resources described herein, or provide information about nonarcheological TCRs, that information is documented separately in the AB 52 tribal consultation record between the tribe(s) and lead agency and summarized in the TCRs section of the CEQA document, if applicable.

1.4 Report Organization
The following report documents the study and its findings and was prepared in conformance with the California Office of Historic Preservation’s (OHP) Archaeological Resource Management Reports:

Recommended Contents and Format. Appendix A includes ECORP’s request of the records search with the California Historical Resources Information System (CHRIS) and historical society coordination. Appendix B contains documentation of a search of the Sacred Lands File. Appendix C presents photographs of the Project Area.

Sections 6253, 6254, and 6254.10 of the California Code authorize state agencies to exclude archaeological site information from public disclosure under the Public Records Act. In addition, the California Public Records Act (Government Code Section 6250 et seq.) and California’s open meeting laws (The Brown Act, Government Code Section 54950 et seq.) protect the confidentiality of Native American cultural place information. Because the disclosure of information about the location of cultural resources is prohibited by the Archaeological Resources Protection Act of 1979 (16 U.S. Code 552 470hh) and Section 307103 of the NHPA, it is exempted from disclosure under Exemption 3 of the federal Freedom of Information Act (5 U.S. Code 552) Likewise, the Information Centers of the CHRIS maintained by the OHP 955

prohibit public dissemination of records search information as well as the records of ECORP’s previous investigations.

2.0 SETTING

2.1 Environmental Setting
The Project Area is located on a gradual incline that slopes from the northeast to the southwest; a more abrupt slope with a change in elevation of approximately 10 feet is in the northeastern section of the Project Area (Figure 1). A drainage that runs from the northeast to southwest passes through the western half Project Area. Elevations within the Project Area range from 1,398 to 1,524 feet above mean sea level.

2.2 Geology and Soils
U.S. Department of Agriculture’s Natural Resources Conservation Service (NRCS) Web Soil Survey website (NRCS 2023) indicates that the soils within the Project Area consist of:
• Cieneba sandy loam, eroded, 15 to 50 percent slopes;
• Cieneba sandy loam, 5 to 8 percent slopes;
• Cieneba rocky sandy loam, eroded, 15 to 50 percent slopes; • Fallbrook sandy loam, eroded, 8 to 15 percent slopes; • Hanford coarse sandy loam, 2 to 8 percent slopes;
• Monserate sandy loam, 0 to 5 percent slopes; and
• Placentia fine dandy loam, 5 to 15 percent slopes.

A review of geologic area maps for the Project Area shows the soil is composed of types known as Fanglomerate and terrace deposits of sedimentary and metamorphic rock, which are slightly waterworn, heterogeneous fragments of all sizes, deposited in an alluvial fan and later cemented into a firm rock; it is characterized by persistence parallel to the depositional strike and by rapid thinning downdip (Engel, Gay and Rogers 1959)
A moderate potential for buried pre-contact archaeological sites exists within the Project Area due to the presence of the drainage in the western portion of the Project Area and Iodine Springs approximately

0.5 mile northeast of the Project Area along the same drainage.

2.3 Vegetation and Wildlife
The dominant plant community within the Project Area includes nonnative grasses, such as Bermuda grass (Cynodon dactylon), cheeseweed (Malva parviflora), pigweed amaranth (Amaranthus albus), shortpod mustard (Hirschfeldia incana), wild oat (Avena sp.), bromegrass (Bromus diandrus), Russian thistle (Salsola tragus). It also includes native grasses, such as telegraph weed (Heterotheca grandiflora), common sunflower (Helianthus annuus), and jimson weed (Datura wrightii). The Project Area also contains other 956
Archaeological Resources Inventory Report
ECORP Consulting, Inc.

Ronald Reagan Park Project

2022-252.03
trees such as gum trees (Eucalyptus sp.), juniper (Platycladus sp.), olive tree (Olea europaea), mule fat, and tree of heaven (Ailanthus altissima; ECORP 2023).

Wildlife species that may occur within the Project Area include California horned lark (Eremophila alpestris), red-tailed hawk (Buteo jamaicensis), killdeer (Charadrius vociferus), mourning dove (Zenaida macroura), desert cottontail (Sylvilagus audubonii), and California ground squirrel (Otospermophilus beecheyi; ECORP 2023).

3.0 CULTURAL CONTEXT

3.1 Regional Pre-Contact History

3.1.1 Paleo-Indian Period/Terminal Pleistocene (12,000 to 10,000 BP) The first inhabitants of southern California were big game hunters and gatherers exploiting extinct species of Pleistocene megafauna (e.g., mammoth and other Rancholabrean fauna). Local "fluted point" assemblages comprised of large spear points or knives are stylistically and technologically similar to the Clovis Paleo-Indian cultural tradition dated to this period elsewhere in North America (Moratto 1984).

Archaeological evidence for this period in southern California is limited to a few small temporary camps with fluted points found around late Pleistocene lake margins in the Mojave Desert and around Tulare Lake in the southern San Joaquin Valley. Single points are reported from Ocotillo Wells and Cuyamaca Pass in eastern San Diego County and from the Yuha Desert in Imperial County (Rondeau et al. 2007).

3.1.2 Early Archaic Period/Early Holocene (10,000 to 8,500 BP) Approximately 10,000 years ago, at the beginning of the Holocene, warming temperatures, and the extinction of the megafauna resulted in changing subsistence strategies with an emphasis hunting smaller game and increasing reliance on plant gathering. Previously, Early Holocene sites were represented by only a few sites and isolates from the Lake Mojave and San Dieguito complexes found along former lakebeds and grasslands of the Mojave Desert and in inland San Diego County. More recently, southern California Early Holocene sites have been found along the Santa Barbara Channel (Erlandson 1994), in western Riverside County (Goldberg 2001; Grenda 1997), and along the San Diego County coast (Gallegos 1991; Koerper et al. 1991; Warren 1967).

The San Dieguito Complex was defined based on material found at the Harris site (CA-SDI-149) on the San Dieguito River near Lake Hodges in San Diego County. San Dieguito artifacts include large leafshaped points; leaf-shaped knives; large ovoid, domed, and rectangular end and side scrapers; engraving tools; and crescentics (Koerper et al. 1991). The San Dieguito Complex at the Harris site dates to 9,000 to 7,500 years Before Present (BP) (Gallegos 1991). However, sites from this time period in coastal San Diego County have yielded artifacts and subsistence remains characteristic of the succeeding Encinitas Tradition, including manos, metates, core-cobble tools, and marine shell (Gallegos 1991; Koerper et al. 1991). 957

3.1.3 Encinitas Tradition or Milling Stone Period/Middle Holocene (8,500 to 1,250 BP)
The Encinitas Tradition (Warren 1968) and the Milling Stone Period (Wallace 1955) refer to a long period of time during which small mobile bands of people who spoke an early Hokan language foraged for a wide variety of resources including hard seeds, berries, and roots/tubers (yucca in inland areas), rabbits and other small animals, and shellfish and fish in coastal areas. Sites from the Encinitas Tradition consist of residential bases and resource acquisition locations with no evidence for overnight stays. Residential bases have hearths and fire-affected rock indicating overnight stays and food preparation. Residential bases along the coast have large amounts of shell and are often termed shell middens.

The Encinitas Tradition as originally defined (Warren 1968) applied to all of the non-desert areas of southern California. Recently, four patterns within the Encinitas Tradition have been proposed which apply to different regions of southern California (Sutton and Gardner 2010). The Topanga Pattern includes archaeological material from the Los Angeles Basin and Orange County. The Greven Knoll Pattern pertains to southwestern San Bernardino County and western Riverside County (Sutton and Gardner 2010). Each of the patterns is divided into temporal phases. The Topanga Pattern included the Los Angeles Basin and Orange County. The Topanga I phase extends from 8,500 to 5,000 BP and Topanga II runs from 5,000 to 3,500 BP. The Topanga Pattern ended about 3,500 BP with the arrival of Takic speakers, except in the Santa Monica Mountains where the Topanga III phase lasted until about 2,000 BP.

The Encinitas Tradition in inland areas east of the Topanga Pattern (southwestern San Bernardino County and western Riverside County) is the Greven Knoll Pattern (Sutton and Gardner 2010). Greven Knoll I (9,400 to 4,000 BP) has abundant manos and metates. Projectile points are few and are mostly Pinto points. Greven Knoll II (4,000 to 3,000 BP) has abundant manos and metates and core tools. Projectile points are mostly Elko points. The Elsinore site on the east shore of Lake Elsinore was occupied during Greven Knoll I and Greven Knoll II. During Greven Knoll I faunal processing (butchering) took place at the lakeshore and floral processing (seed grinding), cooking, and eating took place farther from the shore.

The primary foods were rabbit meat and seeds from grasses, sage, and ragweed. A few deer, waterfowl, and reptiles were consumed. The recovered archaeological material suggests that a highly mobile population visited the site at a specific time each year. It is possible that their seasonal round included the ocean coast at other times of the year. These people had an unspecialized technology as exemplified by the numerous crescents, a multi-purpose tool. The few projectile points suggest that most of the small game was trapped using nets and snares (Grenda 1997). During Greven Knoll II, which included a warmer drier climatic episode known as the Altithermal, it is thought that populations in interior southern California concentrated at oases and that Lake Elsinore was one of them. The Elsinore site (CA-RIV-2798) is one of five known Middle Holocene residential sites around Lake Elsinore. Tools were mostly manos, metates, and hammerstones. Scraper planes were absent. Flaked-stone tools consisted mostly of utilized flakes used as scrapers. The Elsinore site during the Middle Holocene was a “recurrent extended encampment” which could have been occupied during much of the year.

The Encinitas Tradition lasted longer in inland areas because Takic speakers did not move east into these areas until circa 1,000 BP. Greven Knoll III (3,000 to 1,000 BP) is present at the Liberty Grove site in Cucamonga (Salls 1983) and at sites in Cajon Pass that were defined as part of the Sayles Complex (Kowta 958
Archaeological Resources Inventory Report
ECORP Consulting, Inc.

1969). Greven Knoll III sites have a large proportion of manos and metates and core tools as well as scraper planes. Kowta (1969) suggested the scraper planes may have been used to process yucca and agave. The faunal assemblage consists of large quantities of lagomorphs (rabbits and hares) and lesser quantities of deer, rodents, birds, carnivores, and reptiles.

3.1.4 Palomar Tradition (1,250 to 150 BP)
The native people of southern California (north of a line from Agua Hedionda to Lake Henshaw in San Diego County) spoke Takic languages which form a branch or subfamily of the Uto-Aztecan language family. The Takic languages are divided into the Gabrielino-Fernandeño language, the Serrano-Kitanemuk group (the Serrano [includes the Vanyume dialect] and Kitanemuk languages), the Tataviam language, and the Cupan group (the Luiseño-Juaneño language, the Cahuilla Language, and the Cupeño language) (Golla 2011). According to Sutton (2009), Takic speakers occupied the southern San Joaquin Valley before 3,500 BP. Perhaps as a result of the arrival of Yokutsan speakers (a language in the Penutian language family) from the north, Takic speakers moved southeast. The ancestors of the Kitanemuk moved into the Tehachapi Mountains and the ancestors of the Tataviam moved into the upper Santa Clara River drainage.

The ancestors of the Gabrielino (Tongva) moved into the Los Angeles Basin about 3,500 BP, replacing the native Hokan speakers. Speakers of proto-Gabrielino reached the southern Channel Islands by 3,200 BP (Sutton 2009) and moved as far south as Aliso Creek in Orange County by 3,000 BP.

Takic people moved south into southern Orange County after 1,250 BP and became the ancestors of the Juaneño. Takic people moved inland from southern Orange County about 1,000 BP, becoming the ancestors of the Luiseño, Cupeño, and Cahuilla. Takic people from the Kitanemuk area moved east along the northern slopes of the San Gabriel Mountains and spread into the San Bernardino Mountains and along the Mojave River becoming the ancestors of the Serrano and the Vanyume.

The material culture of the inland areas where Takic languages were spoken at the time of Spanish contact is part of the Palomar Tradition (Sutton 2011). San Luis Rey I Phase (1,000 to 500 BP) and San Luis Rey II Phase (500 to 150 BP) pertain to the area occupied by the Luiseño at the time of Spanish contact.

The Peninsular I (1,000 to 750 BP), II (750 to 300 BP), and III (300 to 150 BP) Phases are used in the areas occupied by the Cahuilla and Serrano (Sutton 2011).

San Luis Rey I is characterized by Cottonwood Triangular arrow points, use of bedrock mortars, stone pendants, shell beads, quartz crystals, and bone tools. San Luis Rey II sees the addition of ceramics, including ceramic cremation urns, red pictographs on boulders in village sites, and steatite arrow straighteners. San Luis Rey II represents the archaeological manifestation of the antecedents of the historically known Luiseño (Goldberg 2001). During San Luis Rey I there were a series of small permanent residential bases at water sources, each occupied by a kin group (probably a lineage). During San Luis Rey II people from several related residential bases moved into a large village located at the most reliable water source (Waugh 1986). Each village had a territory that included acorn harvesting camps at higher elevations. Villages have numerous bedrock mortars, large dense midden areas with a full range of flaked and ground stone tools, rock art, and a cemetery.

3.2 Local Pre-Contact History
The Peninsular Complex is the further inland counterpart to the San Luis Rey Complex of the Palomar Tradition which dominated the areas south and east of the Los Angeles Basin during the Late Period. The Peninsular complex developed in and around the San Jacinto Mountains and the northern portion of Lake Cahuilla. It is divided into three temporal phases characterized by shifts in subsistence, material culture, settlement patterns, and mortuary practices, among other traits (Sutton 2011).

3.2.1 Peninsular I (950 to 750 BP)
This first phase of the Peninsular Complex began approximately 950 BP as populations relocated to the area around Lake Cahuilla as it filled with water. Lasting for about 200 years, the Peninsular I phase is characterized by the appearance of Cottonwood points and bow shaft straighteners as an augmentation of already existing bow and arrow technology. Obsidian sources utilized consisted of Coso Volcanic Field, Obsidian Butte, Bagdad, and others. Ceramic vessels from this phase are comprised of Tumco buff and Salton buff, exhibiting a continuation of use of these materials. The presence of Lake Cahuilla allowed for a shift to lacustrine subsistence and settlement patterns were primarily long-term lakeshore villages with special use sites elsewhere. Rock art was present, but less ubiquitous than in cultural groups to the west.

There was also a continued practice of primary pit cremation in mortuary contexts. Linguistically, this phase was characterized by a Proto-Cahuilla language splitting from Proto-Cupan and moving east (Sutton 2011).

3.2.2 Peninsular II (750 to 350 BP)
The shift to the Peninsular II phase began 750 BP, lasting approximately 450 years. Material culture from this time included the continued use of Tumco buff and Salton buff pottery with the addition of Tizon brownware, ceramic pipes, and ceramic figurines. Obsidian continued to be sourced from Coso Volcanic Field and Obsidian Butte along with other sources. Rock art of the San Luis Rey style replaced the previous Rancho Bernardo style, and cremation practices shifted to secondary container cremations and included mourning ceremonies. Subsistence continued to rely heavily on Lake Cahuilla, with the addition of stone fish trap technology. However, village sites along the lakeshore shifted to short-term occupation, with additional villages for special purposes remaining in use elsewhere. Proto-Cahuilla language characterized this phase, with a possible split of Desert Cahuilla to move east to the norther Coachella Valley (Sutton 2011).

3.2.3 Peninsular III (300 BP to AD 1769)
The third phase in the Peninsular Complex occurred from 300 BP to the time of European contact. During this time, the recession of Lake Cahuilla forced subsistence patterns to become reliant on exclusively terrestrial sources. There was a continuation in the use of Cottonwood and Desert Side-notched points, with Obsidian Butte being the primary source of material. Tizon brown pottery also saw continued use during this phase, however, Tumco buff and Salton buff pottery fell out of use, and Colorado buff was introduced. Rock art from this time demonstrated a loss of the San Luis Rey style, which was replaced with “Cahuilla B” style. Permanent settlements were situated around springs, with movement west into more 960

mountainous areas as Lake Cahuilla dried up. Mortuary practices reverted to primary pit cremations but integrated the mourning ceremonies of Peninsular II culture. The Cahuilla language developed three distinct dialects during this phase (Sutton 2011).

3.3 Ethnohistory
The Luiseño are a Takic-speaking people who occupied what is now western Riverside County and northern San Diego County (the San Luis Rey River drainage) in prehistoric and historic times. The term Luiseño was given by the Spanish to the native groups who were living in this area and who were forcibly removed to Mission San Luis Rey. The Luiseño believe the world was created in the area now known as Temecula and that they have been here since the beginning of time (Temecula Valley Historical Society 2014).

The Luiseño lived in sedentary and autonomous village groups, each with specific subsistence territories encompassing hunting, collecting, and fishing areas. Villages were typically located in valley bottoms, along streams, or along coastal strands near mountain ranges where water was available and village defense was possible. Inland populations had access to fishing and gathering sites on the coast, which they used during the winter months (Bean and Shipek 1978).

Luiseño subsistence was centered around the gathering of acorns, seeds, greens, bulbs, roots, berries, and other vegetal foods. This was supplemented with hunting mammals such as deer, antelope, rabbit, woodrat, ground squirrels, and mice, as well as quail, doves, ducks, and other birds. Bands along the coast also exploited marine resources, such as sea mammals, fish, crustaceans, and mollusks. Inland, trout and other fish were taken from mountain streams (Bean and Shipek 1978).

Hunting was carried out both individually and by organized groups. Tool technology for food acquisition, storage, and preparation reflects the size and quantity of items procured. Small game was hunted with the use of curved throwing sticks, nets, slings, or traps. Bows and arrows were used for hunting larger game.

Dugout canoes, basketry fish traps, and shell hooks were used for near-shore ocean fishing. Coiled and twined baskets were made for food gathering, preparation, storing, and serving. Other items used for food processing included large shallow trays for winnowing chaff from grain, ceramic and basketry storage containers, manos and metates for grinding seeds, and ceramic jars for cooking (Bean and Shipek 1978).

Villages had hereditary chiefs who controlled religious, economic, and territorial activities (Bean and Shipek 1978; Boscana 1933). An advisory council of ritual specialists and shamans was consulted for environmental and other knowledge. large villages located along the coast or in inland valleys may have had more complex social and political structures than settlements controlling smaller territories (Bean and Shipek 1978; Strong 1929).

Most Luiseño villages contained a ceremonial structure, enclosed by circular fencing and located near the center of the village. Houses were semisubterranean and thatched with locally available brush, bark, or reeds. Earth-covered semisubterranean sweathouses were also common and were used for purification and curing rituals (Bean and Shipek 1978).

The Luiseño first came into contact with Europeans in 1769 when the expedition led by Gaspar de Portolá arrived in their territory. That same year, the San Diego Mission was established just to the south, followed by the San Juan Capistrano Mission in 1776 and the San Luis Rey Mission in 1798. Poor living conditions at the missions and introduced European diseases led to a rapid decline of the Luiseño population.

Following the Mission Period (1769-1834), Luiseño Indians scattered throughout southern California.

Some became serfs on the Mexican ranchos, others moved to newly founded pueblos established for them, some sought refuge among inland groups, and a few managed to acquire land grants. Later, many moved to or were forced onto reservations. Although many of their cultural traditions had been suppressed during the Mission Period, the Luiseño were successful at retaining their language and certain rituals and ceremonies. Starting in the 1970s, there was a revival of interest in the Luiseño language and classes were organized. Since then, traditional games, songs, and dances have been performed, traditional foods have been gathered and prepared, and traditional medicines and curing procedures have been practiced (Bean and Shipek 1978).

3.4 Regional History
The first European to visit California was Spanish maritime explorer Juan Rodriguez Cabrillo in 1542.

Cabrillo was sent north by the Viceroy of New Spain (now Mexico) to look for the Northwest Passage.

Cabrillo visited San Diego Bay, Catalina Island, San Pedro Bay, and the northern Channel Islands. The English adventurer Francis Drake visited the Miwok Native American group at Drake’s Bay or Bodega Bay in 1579. Sebastian Vizcaíno explored the coast as far north as Monterey in 1602. He reported that Monterey was an excellent location for a port (Castillo 1978). Vizcaíno also named San Diego Bay to commemorate Saint Didacus. The name began to appear on European maps of the New World by 1624 (Gudde 1998).

Colonization of California began with the Spanish Portolá land expedition. The expedition, led by Captain Gaspar de Portolá of the Spanish army and Father Junipero Serra, a Franciscan missionary, explored the California coast from San Diego to the Monterey Bay Area in 1769. As a result of this expedition, Spanish missions to convert the native population, presidios (forts), and towns were established. The Franciscan missionary friars established 21 missions in Alta California (the area north of Baja California) beginning with Mission San Diego in 1769 and ending with the mission in Sonoma established in 1823. The purpose of the missions and presidios was to establish Spanish economic, military, political, and religious control over the Alta California territory. Mission San Diego was established to convert the Native Americans that lived in the area, known as the Kumeyaay or Diegueño. Mission San Gabriel Archangel was founded in 1771 east of what is now Los Angeles to convert the Tongva or Gabrielino. Mission San Fernando, also in Tongva/Gabrielino territory, was established in 1797. Mission San Juan Capistrano was established in 1776 on San Juan Creek (in what is now southern Orange County) to convert the Agjachemem or Juaneño.

Mission San Luis Rey was established in 1798 on the San Luis Rey River (in what is now northern San Diego County) to convert the Luiseño. Missions San Buenaventura and Santa Barbara were founded in Chumash territory in 1782 and 1786, respectively (Castillo 1978).

Some missions later established outposts in inland areas. An asistencia (mission outpost) of Mission San Luis Rey, known as San Antonio de Pala, was built in Luiseño territory along the upper San Luis Rey River near Mount Palomar in 1810 (Pourade 1961). A chapel administered by Mission San Gabriel Archangel 962

was established in the San Bernardino area in 1819 (Bean and Smith 1978). The present asistencia within the western outskirts of present-day Redlands was built circa 1830 (Haenszel and Reynolds 1975). The missions sustained themselves through cattle ranching and traded hides and tallow for supplies brought by ship. Large cattle ranches were established by Mission San Luis Rey at Temecula and San Jacinto (Gunther 1984). The Spanish also constructed presidios, or forts, at San Diego and Santa Barbara, and a pueblo, or town, was established at Los Angeles. The Spanish period in California began in 1769 with the Portola expedition and ended in 1821 with Mexican independence.

After Mexico became independent from Spain in 1821, what is now California became the Mexican province of Alta California. The Mexican government closed the missions in the 1830s and former mission lands were granted to retired soldiers and other Mexican citizens for use as cattle ranches. Much of the land along the coast and in the interior valleys became part of Mexican land grants or “ranchos” (Robinson 1948). During the Mexican period there were small towns at San Diego (near the presidio), San Juan Capistrano (around the mission), and Los Angeles. The rancho owners lived in one of the towns or in an adobe house on the rancho. The Mexican Period includes the years 1821 to 1848.

The American period began when the Treaty of Guadalupe Hidalgo was signed between Mexico and the United States in 1848. As a result of the treaty, Alta California became part of the United States as the territory of California. Rapid population increase occasioned by the Gold Rush of 1849 allowed California to become a state in 1850. Most Mexican land grants were confirmed to the grantees by U.S. courts, but usually with more restricted boundaries which were surveyed by the U.S. Surveyor General’s office. Land that was not part of a land grant was owned by the U.S. government until it was acquired by individuals through purchase or homesteading. Floods and drought in the 1860s greatly reduced the cattle herds on the ranchos, making it difficult to pay the new American taxes on the thousands of acres they owned.

Many Mexican-American cattle ranchers borrowed money at usurious rates from newly arrived AngloAmericans. The resulting foreclosures and land sales transferred most of the land grants into the hands of Anglo-Americans (Cleland 1941).

3.5 City of Wildomar Area History
Rancho La Laguna was a grant of three square leagues made by Mexican governor Manuel Micheltorena to Julian Manriquez in 1844 (Gunther 1984). Rancho La Laguna included Lake Elsinore and what is now Wildomar. The land grant was confined to the valley floor and did not include the surrounding hills.

After Julian Manriquez died, Rancho La Laguna was sold by his widow to Abel Stearns in 1852. Stearns, who lived in Los Angeles, sold the rancho to Agustín Machado in 1858. Machado and his family lived in an adobe house northwest of the lake. When confirmed by the United States in 1872, the grant had an area of 13,339 acres (Gunther 1984). Machado’s widow and 11 of the 12 children sold most of the rancho to an Englishman, Charles A. Sumner, in 1873. Machado’s oldest son, Juan Machado, retained the house and 513 acres. Sumner mortgaged his property in 1875 and lost the property through foreclosure and a sheriff’s sale in 1877. The new owner, Milton Latham, sold the property to Frederick M. Sumner, brother of the previous owner, Charles A. Sumner. In 1881, ownership was transferred to a San Francisco bank and in 1883 it was purchased by Franklin Heald, William Collier, and Donald Graham (Gunther 1984). The partners subdivided part of the property and began selling lots in what would become the town of 963

Elsinore. The Elsinore post office was established in November 1883 (Gunther 1984). These partners divided the La Laguna Ranch property in 1885 with Heald taking the area north of Corydon Road, which included Lake Elsinore and the town of Elsinore, and Collier and Graham taking the area southeast of Corydon Road, which became Wildomar (Gunther 1984).

Wildomar began as the Car B station, established in 1884 on the California Southern Railroad Company (CSRR), 6 miles south of the Elsinore Junction station (Gunther 1984). The station began as a railroad car on a siding. The name was changed to Wildon and lots were surveyed and platted in 1885. The name Wildon was based on the first names of William Collier and Donald Graham, owners of this part of the former Rancho La Laguna. A new plat was recorded in 1886 with the name changed to Wildomar. The name Wildomar was formed using Wildon plus part of the first name of Margaret Collier, wife of William Collier and sister of Donald Graham.

The original town was between Palomar Street and Grand Avenue and between Gruwell Street and Pasadena Avenue, according to the 1901 edition of the USGS Elsinore Quadrangle. These streets are shown on this map. Buildings were mostly along Central Avenue between Palomar Street and Grand Avenue. The Wildomar post office and the elementary school were established in 1886. With the arrival of many Quaker families from West Branch, Iowa, Wildomar became known as a Quaker colony. Wildomar became one of the original election precincts and school districts when Riverside County was formed in 1893 (Gunther 1984). The development of Wildomar slowed when the CSRR’s tracks in Temecula Canyon were washed out for the final time and not rebuilt in 1892 (Robertson 1998). This severed the connection with San Diego. In 1927 the track in Railroad Canyon washed out and the AT&SF track from Perris to Temecula was abandoned (Gunther 1984), after which Wildomar no longer had rail service. Wildomar remained a rural farming and horse ranching community for most of the twentieth century. Completion of Interstate 15 through the area in the early 1980s led to urban growth. Wildomar was incorporated as a city on July 1, 2008 with a population of 28,000 (Wildomar 2015).

4.2 Records Search Methods
ECORP requested a records search for the Project Area at the Eastern Information Center (EIC) of the CHRIS at the University of California, Riverside on May 9, 2023 (Appendix A). The purpose of the records search was to determine the extent of previous surveys within a 0.5-mile (800-meter) radius of the Proposed Project Area and whether previously documented pre-contact or historic archaeological sites, architectural resources, or traditional cultural properties exist within this area. The EIC has experienced delays and results of the records search are still pending as of the date of this report. A supplemental records search using previous investigations was utilized (ECORP 2016a, 2016b, 2020).

In addition to the official records and maps for archaeological sites and surveys in Riverside County, the following historic references were also reviewed: Built Environment Resource Directory (OHP 2020); Historic Property Data File for Riverside County (OHP 2012); the National Register Information System (National Park Service [NPS] 2023); Office of Historic Preservation, California Historical Landmarks (CHL; OHP 2023); CHL (OHP 1996 and updates); California Points of Historical Interest (OHP 1992 and updates); Directory of Properties in the Historical Resources Inventory (1999); Caltrans Local Bridge Survey (California Department of Transportation [Caltrans] 2019); Caltrans State Bridge Survey (Caltrans 2018); and Historic Spots in California (Kyle 2002).

Other references examined include a RealQuest Property Search and historic General Land Office (GLO) land patent records (Bureau of Land Management [BLM] 2023). Historic maps reviewed include:

ECORP reviewed historic aerial photographs taken in 1938, 1967, 1978, 1982, 1985, 1996, 2002, 2005, and 2009 for any indications of property usage and built environment.

ECORP conducted a search for a local historical registry. The search revealed that the nearest registry is the Wildomar Historical Society, which is an entirely digital repository for the history of the City of Wildomar.

4.3 Sacred Lands File Coordination Methods
In addition to the records search, ECORP contacted the California Native American Heritage Commission (NAHC) on May 9, 2023 to request a search of the Sacred Lands File for the Project Area (Appendix B). This search determines whether the California Native American tribes within the Project Area have recorded Sacred Lands, because the Sacred Lands File is populated by members of the Native American community with knowledge about the locations of tribal resources. In requesting a search of the Sacred Lands File, ECORP solicited information from the Native American community regarding TCRs, but the responsibility to formally consult with the Native American community lies exclusively with the federal and local agencies under applicable state and federal laws. The lead agencies do not delegate government-togovernment authority to any private entity to conduct tribal consultation.

4.4 Tribal Coordination Methods
At the request of the client, ECORP contacted Jessica Valez and Joseph Ontiveros of the Soboba Band of Luiseño Indians via email on June 16, 2023 and invited them to participate in the field effort. One representative monitor from the tribe was present during the field effort.

4.5 Other Interested Party Consultation Methods
ECORP emailed letters to the Wildomar Historical Society and the Riverside Historical Commission on May 9, 2023 to solicit comments or obtain historical information that the repository might have regarding events, people, or resources of historical significance in the area (Appendix A).

4.6 Field Methods
ECORP subjected the Project Area to an intensive pedestrian survey on June 22, 2023 under the guidance of the Secretary of the Interior's Standards for the Identification of Historic Properties (NPS 1983) using 15- meter-spaced transects (Figure 2). ECORP expended 2 person days in the field. ECORP examined the ground surface for indications of surface or subsurface cultural resources and inspected the general morphological characteristics of the ground surface ted for indications of subsurface deposits that may be manifested on the surface, such as circular depressions or ditches. 966

Whenever possible, ECORP examined the locations of subsurface exposures caused by such factors as rodent activity, water or soil erosion, or vegetation disturbances for artifacts or for indications of buried deposits. ECORP did not conduct subsurface investigations or artifact collections during the pedestrian survey.

Standard professional practice requires that all cultural resources encountered during the survey be recorded using Department of Parks and Recreation (DPR) 523-series forms approved by the California OHP. The resources are usually photographed, mapped using a handheld Global Positioning System receiver, and sketched as necessary to document their presence using appropriate DPR forms.

5.0 RESULTS

5.1 Records Search
The records search consisted of a review of previous research and literature, records on file with ECORP for previously recorded resources, and historical aerial photographs and maps of the vicinity. In lieu of the pending record search results from the EIC, this study utilizes previous investigations by ECORP.

5.1.1 Previous Research
Due to the delay in CHRIS results, two previous ECORP investigations from 2015 and 2020 (ECORP 2016a, 2016b, 2020) were utilized as proxy results pending the official results from CHRIS. Based on these previous investigations, none of the current Project Area has been previously surveyed for cultural resources. An update to this inventory report will be submitted when the CHRIS results are received. These combined results are summarized in Table 1. Parts of the 0.5-mile buffer to the south of the Project Area (less than 40 percent in total) have been previously surveyed; however, these studies were conducted by other firms and more than 10 years ago.

5.1.2 Records
The OHP’s Built Environment Resource Directory for Riverside County (dated March 3, 2020) included one resource within 0.5 mile of the Project Area (OHP 2020). The resource is located southeast of the Project Area. There are a total of 14 properties included on the list in the City of Wildomar.

The National Register Information System (NPS 2023) failed to reveal any eligible or listed properties within the Project Area. The nearest National Register properties are located in the City of Murrieta.

ECORP reviewed resources listed as California Historical Landmarks (OHP 1996) by the OHP (2023) on May 16, 2023. The nearest listed landmark is #1005 Santa Rosa Rancho; the plaque is located 6 miles southwest of the Project Area.

Historic Spots in California (Kyle 2002) mentions a painted rock located south of the City of Corona, 12 miles northwest of the Project Area.

Historic GLO land patent records from the BLM’s patent information database (BLM 2023) revealed that the northern half of Section 36 was issued on August 25, 1880 and patented to the State of California under the California Enabling Acton of March 3, 1853 for the purpose of supporting public schools.

A RealQuest online property search for APNs 376-350-009 (20 acres) and 376-350-017 (7 acres) revealed that the properties consists of a total of 27 acres of public vacant land and miscellaneous land. No other property history information was on record with RealQuest.

The Caltrans Bridge Local and State Inventories (Caltrans 2018, 2019) did not list any historic bridges within 0.5 mile of the Project Area.

The Handbook of North American Indians (Castillo 1978) mentions a Luiseño rancheria in the City of Temecula.

5.1.3 Map Review and Aerial Photographs
The review of historical aerial photographs and maps of the Project Area provides information on the past land uses of the property and potential for buried archaeological sites. This information shows the Project Area was vacant and not developed.
 An aerial photograph from 1938 show the Project Area as vacant land.  The 1943 USGS Murrieta, California topographic quadrangle map (1:62,500 scale) depicts the Project Area as vacant land.
 The 1953 USGS Murrieta, California topographic quadrangle map (1:24,000 scale) also depicts the Project Area as vacant land.
 An aerial photograph from 1967 shows the Project Area as agricultural land without any built environment features.
 The 1973 USGS Murrieta, California topographic quadrangle map (1:24,000 scale) depicts the Project Area as vacant land.
 An aerial photograph from 1978 shows the Project Area as mostly unchanged with some potential agricultural buildings and irrigation features in the southwest section of the Project Area.  Aerial photographs from 1982, 1985, and 1996 show an unpaved north–south-oriented road to the east of the Project Area, which would eventually become the present-day paved Wildomar Trail. The Project Area and surrounding land remain vacant and undeveloped.  Aerial photographs from 2002, 2005 and 2009 show the Ronald Reagan Elementary School in various stages of construction to completion, south of the Project Area. The photographs also show housing development to the east of the Project Area.

In sum, the Project Area has been undeveloped and vacant at least since 1938 and is located north and west of Ronald Reagan Elementary School.

5.2 Sacred Lands File Results
The search of the Sacred Lands File by the NAHC failed to indicate the presence of Native American cultural resources within the Project Area. A record of all correspondence to date is provided in Appendix B.

5.3 Tribal Coordination Results
A tribal monitor, Jesse Resvaloso with the Soboba Band of Luiseño Indians, accompanied the ECORP archaeologists during the survey. The Soboba Band of Luiseño Indians responded on June 20, 2023 with confirmation of their participation.

5.4 Other Interested Party Consultation Results
ECORP has not received any responses to the letters sent to the Wildomar Historical Society and the Riverside Historical Commission as of the date of the preparation of this document.

5.5 Field Survey Results
ECORP surveyed the Project Area for cultural resources on June 22, 2023. Approximately 95 percent of the Project Area was covered by dense vegetation and no greater than 5 percent of the ground surface was visible. The 5 percent of the Project Area that was not covered by dense vegetation comprised small patches that were scattered mostly on the western side of the Project Area; these patches had only 20 percent ground surface visibility due to the presence of vegetation. Dead grass covered the majority of the surface level in between the dense vegetation, which were as tall as 5 feet. A north–south-oriented drainage that passes through the Project Area was impassable at its northern end due to its indiscernible depth and the presence of dense vegetation on either side. The archaeologists encountered a small, undiagnostic irrigation feature on the western side of the Project Area, comprising a small concrete foundation (most of which was covered by vegetation), two plastic PVC pipes, a larger metal pipe, and a T-shaped stand. No dates, words, or symbols were discernible on the visible surfaces. The earliest aerial photographs potentially depicting these resources are from 1978, and it is clear no resources appear in the 1967 aerial photograph. The presence of modern polyvinyl chloride pipe within this resource and lack of any temporally diagnostic features leads to the determination that this is a modern irrigation feature. 971

6.0 MANAGEMENT CONSIDERATIONS

6.1 Conclusions
Data from existing available records searches and the 2023 field survey did not yield any historic-period or pre-contact cultural resources within the Project Area. However, this additional research does not replace an official records search from the EIC and the cultural resource study may not be considered complete by 972

the lead agency until the results and any additional research is completed, if required. Until the CHRIS results for this project are provided, no conclusions or recommendations can be made at this time.

6.2 Likelihood for Subsurface Cultural Resources
A moderate potential for buried pre-contact archaeological sites exists within the Project Area due to the presence of the drainage in the western portion of the Project Area and Iodine Springs approximately

0.5 mile northeast of the Project Area along the same drainage.

6.3 Recommendations
Until the CHRIS results for this project are provided, no conclusions or recommendations can be made at this time.

RE: Cultural Resources Identification Effort for the Ronald Reagan Sports Park Project, Riverside County, California
Dear Riverside Historical Commission:

ECORP Consulting, Inc. has been retained to assist in the planning of the development on the project indicated above. The proposed project consists of approximately 27 acres located in the sectioned portions of Township 6 South Range 3 West, Santa Margarita Watershed as depicted on the enclosed map. The property is located behind the Ronald Reagan Elementary School in Wildomar. As part of the identification effort, we are seeking information from all parties that may have knowledge of or concerns with historic properties or cultural resources in the area of potential effect.

Included are maps showing the project area outlined. We would appreciate input on this undertaking from the historical society with concerns about possible cultural properties or potential impacts within or adjacent to the area of potential effect. If you have any questions, please contact me at (909) 255-2634 or [email protected].

Thank you in advance for your assistance in our cultural resource management study.

Sincerely,
