Habitat Assessment and MSHCP Consistency Analysis
Executive Summary
This report contains the findings of Michael Baker International’s (Michael Baker) habitat assessment and Western Riverside County Multiple Species Habitat Conservation Plan (MSHCP) consistency analysis for the proposed Sunset Crossing Tentative Tract Map (TTM) 38443 (project or project site) located in the City of Moreno Valley, Riverside County, California. Michael Baker biologists conducted a field survey/habitat assessment on April 12, 2022. The field survey was conducted to characterize existing site conditions and assess the potential for special -status1 biological resources to occur within the project site and a 50 -foot buffer (survey area) that could pose a constraint to implementation of the proposed project.

According to the Western Riverside County Regional Conservation Authority’s (RCA) online MSHCP Information Application (RCA 2018), the survey area is not located within any Subunits, Criteria Cells, Conservation Areas, Cores/Linkages, or Public/Quasi -Public Lands identified by the MSHCP. However, the survey area is located within a designated survey area for burrowing owl (Athene cunicularia [BUOW]) according to the RCA’s online MSHCP Information Application (RCA 2018).

The survey area is located within a partially developed portion of the City of Moreno Valley, east of Nason Street and north of Bay Avenue. Natural habitats within the survey area have been eliminated due to routine weed abatement activities (i.e., disking, tilling), resulting in heavily disturbed and compacted surface soils.

As such, native vegetation communities do not occur, and t he survey area is primarily comprised of disturbed land that is dominated by ruderal/weedy and ornamental plant species.

There were no special-status plant species observed within the survey area during the field survey and all special-status plant species identified during the literature review and records search are not expected to occur within the survey area based on existing site conditions and a review of specific- specific habitat preferences, occurrence records, known distributions, and elevation ranges.

One (1) special-status wildlife species that was observed during the field survey included: Cooper’s hawk (Accipiter cooperii; a State Watch List [WL] species). Based on the results of the field survey and a review of specific habitat preferences, occurrence records, known distributions, and elevation r anges, it was determined that the survey area has a low potential to support BUOW (a State Species of Special Concern [SSC]), California horned lark (Eremophila alpestris actia ; a State WL species), western mastiff bat (Eumops perotis californicus; a State SSC), and western yellow bat (Lasiurus xanthinus; a State SSC). All remaining special-status wildlife species identified during the literature review and records search are not expected to occur within the survey area.

Due to the presence of suitable foraging habitat for BUOW, focused surveys were conducted to confirm the presence/absence of BUOW within the project site and a species-specific 500 -foot buffer and analyze potential impacts that could occur as a result of the proposed pro ject. Focused surveys were conducted by

1 As used in this report, “special -status” refers to species that are either federally -/State-listed, proposed, or candidates; plant species that have been designated a California Rare Plant Rank by the California Native Plant Society; wildlife species that are designated by the California Department of Fish and Wildlife as Fully Protected, Species of Special Concern, or Watch List; State/locally rare vegetation communities; or species covered under the Western Riverside County Multiple Species Habitat Conservation Plan.

a qualified biologists during the 2022 breeding season (March 1 to August 31) in accordance with Burrowing Owl Survey Instructions for the Western Riverside County Multiple Species Habitat Conservation Plan (RCA 2006). No BUOWs or sign were found during the focused surveys and the species is presumed absent.

Two (2) drainage features (Aquatic Feature 1 [AF-1] and Aquatic Feature 2 [AF-2]) occur within the survey area and would fall under regulatory authority of the Regional Water Quality Control Board (RWQCB) and the California Department of Fish and Wildlife (CDFW). Based on a review of the conceptual site plan, approximately 0.37 acre of impacts to RWQCB jurisdiction (non -wetland waters of the State) are anticipated, comprised of 0.27 acre of permanent impacts within the project site and 0.10 acre of temporary impacts within the survey area, as well as a total of 0.39 acre of impacts to CDFW jurisdiction , consisting of 0.27 acre of permanent impacts and 0.10 acre of temporary impacts to vegetated streambed, and <0.01 acre of permanent impacts and 0.02 acre of temporary impacts to associated riparian habitat. Therefore, it is anticipated t hat the project applicant would need to obtain the following regulatory permits prior to impacts occurring within jurisdictional areas: 1) Waste Discharge Requirement from the RWQCB, and 2) Section 1602 Streambed Alteration Agreement from CDFW.

AF-1 and AF -2 would qualify as riparian/riverine resources pursuant to Section 6.1.2 of the MSHCP; a total of approximately 0.37 acre of riverine habitat and 0.02 acre of riparian habitat occur within the project site. Riparian/riverine resources within the survey area do not provide suitable habitat for western yellow - billed cuckoo ( Coccyzus americanus occidentalis), southwestern willow flycatcher ( Empidonax traillii extimus), least Bell’s vireo (Vireo bellii pusillus), or fairy shrimp, nor is vernal pool habitat present.

Habitat Assessment and MSHCP Consistency Analysis
Section 1 Introduction
This report contains the findings of Michael Baker International’s (Michael Baker) habitat assessment and Western Riverside County Multiple Species Habitat Conservation Plan (MSHCP) consistency analysis for the proposed Sunset Crossing Tentative Tract Map (TTM) 38443 (project or project site) located in the City of Moreno Valley, Riverside County, California. Michael Baker biologists conducted a field survey/habitat assessment on April 12, 2022. The field surveys were conducted to characterize existing site conditions and assess the potential for special -status2 biological resources to occur within the project site and a 50-foot buffer (survey area) that could pose a constraint to implementation of the proposed project. Special attention was given to the suitability of the habitat within the survey area and its potential to support special -status biological resources that were identified by the California Department of Fish and Wildlife (CDFW) California Natural Diversity Database RareFind 5 ( CNDDB; CDFW 2022a), the CNDDB Biogeographic Information and Observation System (CDFW 202 2b), the California Native Plant Society (CNPS) Inventory of Rare and Endangered Plants of California ( CIRP; CNPS 202 2), the United State Fish and Wildlife Service (USFWS) Information for Planning and Consultation Project Planning Tool (IPaC; USFWS 2022a), the Western Riverside County Regional Conservation Authority’s (RCA) online MSHCP Information Application (RCA 2018), and other databases as potentially occurring in the vicinity of the survey area.

1.1 PROJECT LOCATION
The project site is located within the City of Moreno Valley, generally to the north of Perris Reservoir, east of Interstate 215 (I-215), south of State Route 60 (SR-60), and west of SR-79 (refer to Figure 1, Regional and Project Vicinity). The project site is depicted in Section 10, Township 3 South, Range 3 West , on the United States Geological Survey ’s (USGS) Sunnymead, California 7.5-minute quadrangle. Specifically, the project site is located north of Bay Avenue , south of Cottonwood Avenue , west of Marion Road, and east of Nason Street on assessor’s parcel numbers (APN) 488-190-027, 488- 190-005, and 488-190-028 (refer to Figure 2, Project Site).

1.2 PROJECT DESCRIPTION
The proposed project includes the development of up to 133 residential units, a water basin, a park, and road construction on 29.39 acres (refer to Appendix A, Proposed Site Plan).

2 As used in this report, “special -status” refers to species that are either federally -/State-listed, proposed, or candidates; plant species that have been designated a California Rare Plant Rank by the California Native Plant Society; wildlife species that are designated by the California Department of Fish and Wildlife as Fully Protected, Species of Special Concern, or Watch List; State/locally rare vegetation communities; or species covered under the Western Riverside County Multiple Species Habitat Conservation Plan

Habitat Assessment and MSHCP Consistency Analysis
Section 2 Methodology
Prior to conducting the field survey, Michael Baker conducted thorough literature reviews and records searches to determine which special-status biological resources have the potential to occur on or within the general vicinity of the survey area. A general habitat assessment or field survey was conducted in order to document existing biological conditions and determine the potential for special -status plant and wildlife species to occur within the survey area.

2.1 LITERATURE REVIEW
Prior to conducting the field survey, literature reviews and records searches were conducted within a 5-mile radius for special-status biological resources potentially occurring on or within the vicinity of the survey area. Previous special -status plant and wildlife species occurrenc e records within the USGS El Casco, Perris, Riverside East, Steele Peak, and Sunnymead, California 7.5-minute quadrangles were determined through a query of the CNDDB (CDFW 2022a) and CIRP (CNPS 2022), and for the project region through a review of the IPaC (USFWS 2022a).

The current regulatory/conservation statuses of special -status plant and wildlife species were verified through lists and resources provided by the CDFW, specifically the Special Animals List (CDFW 2022c), Special Vascular Plants, Bryophytes, and Lichens List (CDFW 2022 d), State and Federally Listed Endangered and Threatened Animals of California (CDFW 2022 e), and State and Federally Listed Endangered, Threatened, and Rare Plants of California (CDFW 2022f). USFWS-designated Critical Habitat for species listed under the federal Endangered Species Act (FESA) was reviewed online via the Environmental Conservation Online System: Threatened and Endangered Species Active Critical Habitat Report (USFWS 2022b). In addition, Michael Baker reviewed previously prepared reports, survey results, and literature, as available, detailing the biological resources previously observed on or within the vicinity of the survey area to understand existing site conditions, confirm pr evious species observations, and note the extent of any disturbances, if present, that have occurred within the survey area that would otherwise limit the distribution of special-status biological resources. Standard field guides and texts were reviewed for specific habitat requirements of special-status species, as well as the following resources:
• Calflora Database (Calflora 2022)
• Google Earth Pro Historical Aerial Imagery from 1985 to 2021 (Google, Inc. 2021) • Species Accounts provided by Birds of the World (Billerman et. al 2020) • Cornell Lab of Ornithology’s eBird Database (eBird 2022) • Custom Soil Resource Report for Western Riverside Area, California (United States Department of Agriculture [USDA] 2022)
• National Wetlands Inventory Mapper (USFWS 2022c)

Refer to Section 6 for a complete list of technical references that were reviewed by Michael Baker throughout the course of the habitat assessment.

2.2 FIELD SURVEY
Michael Baker biologists Ryan Winkleman and Lauren Mapes inventoried and evaluated the extent and conditions of the vegetation communities found within the boundaries of the project site and a 50-foot buffer (survey area) and confirmed existing conditions within the survey area on April 12, 2022. Michael Baker biologists were not able to survey the entire survey area due to access restrictions associated with the private residential propert ies along the project’s northeast and eastern boundary, as well as a temporary construction yard along a porti on of the project’s western boundary. However, the se areas were observed with binoculars from within the project site . Refer to Table 1 below for a summary of the survey date, timing, surveyors, and weather conditions.

April 12, 2022 0830 / 1000 Ryan Winkleman, Lauren Mapes 63 sunny / 66 sunny 1 – 3 According to the RCA’s online MSHCP Information Application (RCA 2018), the survey area is not located within any Subunits, Criteria Cells, Conservation Areas, Cores/Linkages, or Public/Quasi -Public (P/QP) Lands identified by the MSHCP. However, the survey area is located within a designated survey area for burrowing owl (Athene cunicularia [BUOW]).

Vegetation communities preliminarily identified on aerial photog raphs during the literature review were verified in the field by walking meandering transects through the vegetation communities and along boundaries between vegetation communities. Naturally vegetated areas typically have a higher potential to support special-status plant and wildlife species than areas that are highly disturbed or developed, which usually have lower quality and/or reduced amounts of habitat for wildlife. All plant and wildlife species observed during the habitat assessment, as well as dom inant plant species within each vegetation community, were recorded in a field notebook, as described below. In addition, site characteristics such as soil condition, topography, hydrology, anthropogenic disturbances, indicator species, and the overall condition of on-site vegetation communities were recorded.

2.3 VEGETATION COMMUNITIES
Vegetation communities occurring within the survey area were delineated on an aerial photograph during the field survey and later digitized using GIS ArcView software to quantify the area of each vegetation community in acres. Vegetation communities were classified in accordance with the vegetation communities provided in A Manual of California Vegetation (Sawyer et al. 2009) and cross referenced with the Preliminary Descriptions of the Terrestrial Natural Communities of California (Holland 1986) and the Section 2 - Methodology

Habitat Assessment and MSHCP Consistency Analysis
2012 Western Riverside Vegetation Map for the purposes of evaluating the presence or absence of special- status vegetation communities identified in the CNDDB records search, which uses the Holland vegetation system.

2.4 PLANTS
Plant species observed during the habitat assessment were identified by visual characterist ics and morphology in the field and recorded in a field notebook. Unfamiliar plants were photographed in the field and identified later using taxonomic guides. Plant nomenclature used in this report follows the Jepson eFlora (Jepson Flora Project 2022) and scientific names are provided immediately following common names of plant species (first reference only).

2.5 WILDLIFE
Wildlife species detected during the habitat assessment by sight, calls, tracks, scat, burrows, nests, or other types of sign were recorded in a field notebook. Field guides used to assist with identification of species during the habitat assessment included The Sibley Guide to Birds (Sibley 2014) for birds, A Field Guide to Western Reptiles and Amphibians (Stebbins 2003) for he rpetofauna, and A Field Guide to Mammals of North America (Reid 2006). Although common names of wildlife species are generally well standardized, scientific names are provided immediately following common names of wildlife species in this report (first reference only). To the extent possible, nomenclature of birds follows the most recent annual supplement of the American Ornithological Union’s Checklist of North American Birds (Chesser et al. 2019), nomenclature of amphibians and reptiles follows Scientific and Standard English Names of Amphibians and Reptiles of North America North of Mexico, with Comments Regarding Confidence in Our Understanding (Crother 2017), and nomenclature for mammals follows the Bats of the United States and Canada (Harvey et al. 2011) and Revised Checklist of North American Mammals North of Mexico (Bradley et al. 2014).

Section 3 Results and Discussion

3.1 EXISTING CONDITIONS

3.1.1 TOPOGRAPHY AND SOILS
The survey area is located within a moderately developed portion of the City of M oreno Valley, at an elevation of approximately 1, 611 to 1,644 feet above mean sea level with generally flat topography throughout. Based on a review of Google Earth aerial imagery from 1985 to 2021, the project site has been routinely cleared as a result of routine weed abatement activities (i.e., disking, tilling), resulting in heavily disturbed and compacted surface soils. According to the Custom Soil Resource Report for Western Riverside Area, Ca lifornia (USDA 202 2), the survey area is underlain by the following soil units:

Greenfield sandy loam, 2 to 8 percent slopes, eroded (GyC2), Hanford coarse sandy loam, 2 to 8 percent slopes (HcC), Ramona sandy loam, 2 to 5 percent slopes, eroded (RaB2), an d Ramona sandy loam, 0 to 5 percent slopes, severely eroded (RaB3) . Refer to Figure 3 , USDA Soils, for a depiction of soil units that have been mapped within the survey area. In addition, please refer to Appendix B for representative photographs of the survey area taken during the field survey.

3.1.2 SURROUNDING LAND USES
Land uses in the immediate vicinity of the survey area include vacant, residential, and commercial land uses. Vacant, undeveloped land is located to the north, south, and east of the survey area, while residential uses are located along the west, northwest, and northeast boundaries of the site. Additionally, commercial uses were currently being built along the western boundary at the time of the field survey.

3.2 VEGETATION COMMUNITIES AND OTHER LAND USES
Natural habitats within the survey area have been eliminated due to routine weed abatement activities (i.e., disking, tilling), resulting in heavily disturbed and compacted surface soils. As such, native vegetation communities do not occur. The survey area is primarily comprised of disturbed habitat that is dominated by ruderal/weedy and ornamental plant species. In addition, developed areas were also observed along the northern boundary and along the eastern boundary of the survey area. These land cover types are depicted on Figure 4, Vegetatio n Communities and Other Land Uses , and described in further detail below.

Additionally, refer to Appendix C, Plant and Wildlife Species Observed List , for a complete list of plant species observed within the survey area during the field survey.

3.2.1 DISTURBED HABITAT
Disturbed habitat comprises approximately 22.26 acres of the project site and 24.40 acres of the entire survey area. Disturbed areas within the survey area do not comprise a natural plant community and instead consist of unpaved bare ground or areas that have been previously disked or tilled as part of routine weed !>

abatement activities. Surface soils within these areas have been heavily disturbed/compacted as a result of anthropogenic disturbances and are either devoid of vegetation or support non-native, ruderal plant species or early successional plant species. Plant species observed in the disturbed areas include common fiddleneck (Amsinckia intermedia), wild oat (Avena fatua), ripgut brome ( Bromus diandrus), red brome (Bromus madritensis ssp. rubens), short-podded mustard ( Hirschfeldia incana), and telegraph weed (Heterotheca grandiflora). In addition, some individual mulefat ( Baccharis salicifolia) occurs along the northwest boundary of the survey area.

3.2.2 DEVELOPED
Developed areas make up approximately 7.13 acres of the project site and 10.27 acres of the entire survey area. They consist of areas that have been constructed upon or have been physically altered to a degree that native vegetation is no longer supported. Developed areas within the survey area include two previous residential houses, one in the northeast corner and the other along the eastern boundary of the survey area.

In addition, a small portion of the western side of the survey area was being actively used for a construction yard for a commercial development along the project’s western boundary at the time of the field survey (refer to Appendix B, Site Photographs). Remnant residential and residential and business buildings in the northeast corner of the project site that were abandoned sometime between June 23, 2021 and April 12, 2022 were observed during the survey occurring in April 2022. In August 2022, those abandoned buildings were demolished by the previous landowner prior to the purchase by the current project proponent, Highpointe Communities.

3.3 WILDLIFE
Natural vegetation communities provide foraging habitat, nesting/denning sites, and shelter from adverse weather or predati on. This section provides a general discussion of common wildlife species that were detected during the field survey or that are expected to occur based on existing site conditions. The discussion is to be used as a general reference and is limited by the season, time of day, and weather conditions in which the field survey was conducted. Refer to Appendix C for a complete list of wildlife species observed during the field survey.

3.3.1 FISH
No fish or hydrogeomorphic features (e.g., perennial creeks, ponds, lakes, reservoirs) that would support populations of fish were observed in the survey area during the field survey. Therefore, no fish are expected to occur within the survey area.

3.3.2 AMPHIBIANS
No amphibians or hydrogeomorphic features (e.g., perennial creeks, ponds, lakes, reservoirs) that would provide suitable breeding habitat for amphibians were observed within the survey area. Therefore, no amphibian species are expected to occur.

3.3.3 REPTILES
One (1) reptile was observed within the survey area during the field survey, western side-blotched lizard (Uta stansburiana elegans). Since the survey area is primarily disturbed, it is expected to provide suitable habitat for a limited number of reptilian species that are acclimated to edge or urban environments. Reptilian species that may be present within the survey area include Great Basin fence lizard (Sceloporus occidentalis longipes) and San Diego alligator lizard (Elgaria multicarinata webbii).

3.3.4 BIRDS
The survey area provides marginal foraging and nesting habitat for a variety of resident and migrant bird species that are adapted to a high degree of disturbance such as traffic, noise, and light pollution associated with the surrounding development . Twenty-six (26) bird species were detected during the field survey, some of which included house finch ( Haemorhous mexicanus), California towhee ( Melozone crissalis), savannah sparrow ( Passerculus sandwichensis), Say’s phoebe ( Sayornis saya), and western meadowlark (Sturnella neglecta). Refer to Appendix C for a complete list of bird species observed during the field survey.

Nesting birds are protected pursuant to the federal Migratory Bird Treaty Act (MBTA) of 1918 and the California Fish and Game Code (CFGC) 3. To maintain compliance with the MBTA and CFGC, clearance surveys are typically required prior to any ground disturbance or vegetation removal activities to avoid direct and indirect impacts to active bird nests and/o r nesting birds. Consequently, if an active bird nest is destroyed or if project activities result in indirect impacts (e.g., nest abandonment, loss of reproductive effort) to nesting birds, it is considered “take” and is potentially punishable by fines and/or imprisonment .

The survey area provides marginal nesting habitat for year -round and seasonal avian residents as well as migrating songbirds that could occur in the area. Additionally, the survey area provides nesting habitat for avian species that nest on the open ground (e.g., killdeer [Charadrius vociferus], western meadowlark). No nests were observed within the survey area during the field survey.

3.3.5 MAMMALS
One (1) mammal species was observed during the field survey: California ground squirrel (Otospermophilus beecheyi). The survey area and surrounding area provide suitable habitat for a dditional mammalian species adapted to living in edge or urban environments. However, the routine weed abatement and surrounding development limits the potential for mammalian species to occur. Other common mammalian species that may occur within the survey area include coyote ( Canis latrans ), opossum (Didelphis virginiana), striped skunk ( Mephitis mephitis ), desert cottontail ( Sylvilagus audubonii ), and raccoon (Procyon lotor). Bats occur throughout most of southern California and may use the survey area

3 Section 3503 makes it unlawful to take, possess, or needlessly destroy the nest or eggs of any bird, except as otherwise provided by the CFGC or any regulation made pursuant thereto; Section 3503.5 makes it unlawful to take, possess, or destroy any birds in the orders Falconiformes or Strigiformes (birds-of-prey); and Section 3513 makes it unlawful to take or possess any migratory non-game bird except as provided by the rules and regulations adopted by the Secretary of the Interior under provisions of the MBTA, as amended (16 U.S.C. § 703 et seq.).

Section 3 – Results and Discussion

as foraging habitat although it is heavily disturbed. The presence of Mexican fan palms ( Washingtonia robusta), Fremont cottonwood ( Populus fremontii) and other large trees may provide roosting habitat for bats. There were abandoned remnant residential and business buildings in the northeast corner of the project site at the time of the site survey. Bats have been known to occur in the area and are known to occupy these types of remnant building structures. However, these buildings were demolished in August 2022 by the previous landowner prior to the purchase by the current project proponent, Highpointe Communities and therefore no longer support bat habitat.

3.4 WILDLIFE CONNECTIVITY
Wildlife corridors and linkages are key features for wildlife movement between habitat patches. Wildlife corridors are generally defined as those areas that provide opportunities for individuals or local populations to conduct seasonal migrations, permanent dispersals, or daily commutes, while linkages generally refer to broader areas that provide movement opportunities for multiple keystone/focal species or allow for propagation of ecological processes (e.g., for moveme nt of pollinators), often between areas of conserved land.

The survey area is located within a moderately developed area of Moreno Valley but has undeveloped, vacant land around it, particularly to the north and south that could function as something of a movement corridor for mammals . However, surrounding roads and development have fragmented the connection between the survey area and surrounding open space and naturally occurring vegetation communities. The disturbed landscape of the survey area and absence of vegetation for cover most likely precludes the movement of wildlife through the survey area. Further, elevated noise levels, vehicle traffic, lighting, and human presence associated with Nason Street, Alessandro Boulevard, Cottonwood Avenue, and surrounding residential development all decrease the suitability of the survey area to be used as a wildlife movement corridor or linkage.

3.5 SPECIAL-STATUS BIOLOGICAL RESOURCES
The CNDDB , CIRP, and IPaC were queried for reported locations of special -status plant and wildlife species as well as special -status natural vegetation communities in the USGS El Casco, Perris, Riverside East, Steele Peak, and Sunnymead, California 7.5-minute quadrangles. The field survey was conducted to assess the conditions of the habitat(s) within the boundaries of the survey area to determine if the existing vegetation communities, at the time of the field survey, have the potential to provide suitable habitat(s) for special-status plant and wildlife species. Additionally, the potentials for special-status species to occur within the survey area were determined based on the reported locations in the CNDDB and CIRP and the following:
• Present: the species was observed or detected within the survey area during the field survey. • High: Occurrence records (within 20 years) indicate that the species has been known to occur on or within one mile of the survey area and the site is within the normal expected range of this Section 3 – Results and Discussion
Sunset Crossing TTM 38443 13
Habitat Assessment and MSHCP Consistency Analysis
species. Intact, suitable habitat preferred by this species occurs within the survey area and/or there is viable landscape connectivity to a local known extant population(s) or sighting(s). • Moderate: Occurrence records (within 20 years) indicate that the species has been known to occur within one mile of the survey area and the site is within the normal expected range of this species. There is suitable habitat within the survey area, but the site is ecologically isolated from any local known extant populations or sightings.
• Low: Occurrence records (within 20 years) indicate that the species has been known to occur within five miles of the survey area, but the site is outside of the normal expected range of the species and/or there is poor quality or marginal habitat within the survey area. • Not Expected: There are no occurrence records of the species occurring within five miles of the survey area, there is no suitable habitat within the survey area, and/or the survey area is outside of the normal expected range for the species.

The CNDDB, CIRP, and IPaC searches identified forty (40) special-status plant species and forty-three (43) special-status wildlife species as having been previously recorded within the USGS El Casco, Perris, Riverside East , Steele Peak, and Sunnymead, California 7.5-minute quadrangles. In addition, t hree (3) special-status vegetation communities were identified in the literature search results. Special-status plant and wildlife species were evaluated for their potential to occur within the survey area based on habitat preferences, availability and quality of suitable habitat, and known distributions. Special-status biological resources identified during the literature review as having the potential to occur within the vicinity of the survey area are presented in Table D-1: Potentially Occurring Special -Status Biological Resources , provided in Appendix D.

3.5.1 SPECIAL-STATUS PLANT SPECIES
Forty (40) special-status plant species have been recorded in the USGS El Casco, Perris, Riverside East, Steele Peak, and Sunnymead, California 7.5-minute quadrangles by the CNDDB, CIRP, and IPaC (refer to Appendix D). No special-status plant species were observed within the survey area during the field survey.

The survey area is primarily comprised of disturbed/ruderal non-native herbs and grasses. Vegetation that is present primarily consists of common wild oat , ripgut brome, short -podded mustard, and horehound (Marrubium vulgare). Additionally, the routine weed abatement within the survey area and surrounding developed land uses have reduced the potential for the survey area to provide suitable habitat for special - status plant species. Based on existing site conditions and a review of specific habitat preferences, occurrence records, known distributions, and elevation r anges, it was determined that the special -status plant species identified by the CNDDB , CIRP, and IPaC databases are not expected to occur within the survey area.

3.5.2 SPECIAL-STATUS WILDLIFE SPECIES
Forty-three (43) special-status wildlife species have been recorded in the USGS El Casco, Perris, Riverside East, Steele Peak, and Sunnymead, California 7.5-minute quadrangles by the CNDDB (refer to Appendix Section 3 – Results and Discussion
Sunset Crossing TTM 38443 14
Habitat Assessment and MSHCP Consistency Analysis
D). One (1) special-status wildlife species was observed during the field survey: Cooper’s hawk (Accipiter cooperii; a State Watch List [WL] species). One individual Cooper’s hawk was observed foraging across the survey area. Based on the results of the field survey and a review of specific habitat preferences, occurrence records, known distributions, and elevation ranges, it was determined that the survey area has a low potential to support BUOW (a State Species of Special Concern [SSC]), California horned lark (Eremophila alpestris actia; a State WL species), western mastiff bat (Eumops perotis californicus; a State SSC), and western yellow bat ( Lasiurus xanthinus ; a State SSC). All remaining special-status wildlife species identified by the CNDDB database are not expected to occur within the survey area.

Due to regional significance in western Riverside County and the presence of a known population in the project vicinity (CDFW 2022a), the potential occurrence of Stephens’ kangaroo rat (Dipodomys stephensi [SKR]) is described in further detail below. In addition, the potential occurrence of BUOW is described in further detail in Section 4.6.3.

Stephens’ Kangaroo Rat
The SKR is 1 of 19 subspecies of the kangaroo rat ( genus Dipodomys) that comprise a distinct group of rodents from the family Heteromyidae. SKR is federally listed as endangered and State listed as threatened.

SKR occurs in western Riverside County, existing in fragmented populations due to the urban landscape.

The northern end of SKR’s range in western Riverside County extends into southwestern San Bernardino County and the southern end extends into northern San Diego County. Preferred habitats include open grasslands and sparse coastal sage scrub approximately 180 to 4,101 feet above mean sea level. SKR prefers open habitats with less than 50% protective cover with soft, well -drained sandy substrates for building burrows. This species is nocturnal and solitary, spending little time above ground.

Separate from the MSHCP, USFWS and CDFW issued the Riverside County Habitat Conservation Agency a Section 10(a) Permit and CFGC Section 2081 Management Authorization in 1996 establishing the Long- Term Stephens’ Kangaroo Rat Habitat Conservation Plan (SKR HCP ; RCA 1996). Based on a review of the SKR HCP, the survey area is located outside the boundaries of the SKR HCP and associated Core Reserves; the San Jacinto Core Reserve is located approximately 2.5 miles to the southeast of the survey area.

According to the CNDDB, there are eight (8) occurrence records for SKR within the USGS Sunnymead, California 7.5-minute quadrangle (CDFW 2022a). The closest extant occurrence record was recorded in 1989 in M oreno Valley , approximately 0.25-mile northeast of the survey area . The undeveloped areas surrounding the northern side of Perris Reservoir, approximately 2 miles from the survey area, are also known to support a well-established SKR population (CDFW 2022a).

Suitable sparse coastal sage scrub and open grassland habitat with sandy soils preferred by this species for burrowing are not present within the survey area. The survey area is comprised of disturbed habitat that is subject to routine weed abatement, resulting in heavily disturbed and compacted surface soils which likely preclude this species from occurring . Further, ongoing weed abatement on-site further reduces the suitability of the survey area to support SKR. Although the survey area is approximately 2 miles from a well-established population to the north of Perris Reservoir, the site is separated by extensive development, Section 3 – Results and Discussion
Sunset Crossing TTM 38443 15
Habitat Assessment and MSHCP Consistency Analysis
primarily residential, and as a result combined with the lack of suitable on-site habitat the survey area is not expected to support SKR.

3.5.3 SPECIAL-STATUS VEGETATION COMMUNITIES
Three (3) special-status vegetation communities have been reported in the USGS El Casco, Perris, Riverside East, Steele Peak, and Sunnymead, California 7.5-minute quadrangles by the CNDDB: Southern Coast Live Oak Riparian Forest , Southern Cottonwood Willow Riparian Forest , and Southern Sycamore Alder Riparian Woodland. No special-status vegetation communities were observed within the survey area during the field survey.

3.6 LOCAL POLICIES AND ORDINANCES

3.6.1 CITY OF MORENO VALLEY MUNICIPAL CODE
The City of Moreno Valley’s Municipal Code addresses tree removal on all land uses, for all projects, in all districts requiring City approval. The Moreno Valley Municipal Code addresses requirements for preservation and protection of heritage trees within the City located on both private and public property.

Under Title 9 Chapter 9.17 of the Moreno Valley Municipal Code, the City has identified two tree species as “heritage trees.” The olive trees (Olea europaea) located near the northwestern corner of the site qualify as heritage trees according to the definition in Chapter 9.17.030, which states that heritage trees include any tree which “defines the historical and cultural character of the city including older Palm and Olive trees, and/or any tree designated as such by official action.” In addition, some of the trees surrounding abandoned residences that were demolished in August 2022 may qualify as “heritage trees” according to the definition in Chapter 9.17.030, which states that heritage trees include any tree which “is fifteen (15) inch diameter measured twenty-four (24) inches above ground level or that have reached a height of fifteen (15) feet or greater.” Under Chapter 9.17.030 of the Moreno Valley Municipal Code, the removal of heritage trees requires the review of the ecological historical preservation board.

It is Michael Baker’s determination that there are trees within the survey area that potentially fit the City of Moreno Valley’s definition of heritage trees. Michael Baker recommends that an arborist conduct a tree survey on-site to determine which trees, if any, qualify as heritage trees.

3.7 CRITICAL HABITAT
Under the definition used by the FESA, “Critical Habitat” refers to specific areas within the geographical range of a species that were occupied at the time it was listed that contain the physical or biological features that are essential to the survival and eventual recovery of that species and that may require special management considerations or protection, regardless of whether the species is still extant in the area. Areas that were not known to be occupied at the time a species was listed can also be designated as Critical Habitat if they contain one or more of the physical or biological features that are essential to that species’ conservation and if the occupied areas are inadequate to ensure the species’ recovery. If a project may result in take or adverse modification to a species’ designated Critical Habitat and the project has a federal nexus, Section 3 – Results and Discussion
Sunset Crossing TTM 38443 16
Habitat Assessment and MSHCP Consistency Analysis
the project proponent may be required to provide suitable mitigation. Projects with a federal nexus include those that occur on federal lands, require federal permits (e.g., federal Clean Water Act [CWA] Section 404 permit), or receive any federal oversight or funding. If there is a federal nexus, then the federal agency that is responsible for providing funds or permits would be required to consult with the USFWS under the FESA.

The survey area is not located within any federally designated Critical Habitat (refer to Figure 5 , Critical Habitat).

3.8 STATE AND FEDERAL JURISDICTIONAL AREAS
There are three agencies that regulate activities within inland streams, wetlands, and riparian areas in California. The United States Army Corps of Engineers (USACE) Regulatory Branch regulates discharge of dredged or fill material into waters of the U.S. (WoUS) pursuant to Section 404 of the CWA and Section 10 of the Rivers and Harbors Act. Of the State agencies, the Regional Water Quality Control Board (RWQCB) regulates discharges to waters of the State (WotS), including wetlands, pursuant to Section 401 of the CWA, Section 13263 of the California Porter -Cologne Water Quality Control Act (Porter -Cologne Act), and State Wetland Definition and Procedures for Discharges of Dredged or Fill Material to Waters of the State ; and the CDFW regulates alterations to lakes, streambeds, and riparian habitats pursuant to Section 1600 et seq. of the CFGC.

As documented in the Delineation of State and Federal Jurisdictional Waters (Michael Baker 2022), two (2) drainage features were documented within the boundaries of the survey area as follows: Aquatic Feature 1 (AF-1) and Aquatic Feature 2 (AF -2). Neither feature qualified as a wetland. Refer to Table 2 and the following sections for a summary of jurisdictional features documented within the survey area.

3.8.1 UNITED STATES ARMY CORPS OF ENGINEERS
The USACE regulates discharge of dredged or fill material into WoUS pursuant to Section 404 of the CWA and Section 10 of the Rivers and Harbors Act. No USACE jurisdiction occurs in association with the project site, as neither AF -1 nor AF -2 exhibit any downstream surface connection (significant nexus) to a Relatively Permanent Water or a Traditionally Navigable Water.

3.8.2 REGIONAL WATER QUALITY CONTROL BOARD
The RWQCB regulates discharges to surface waters pursuant to Section 401 of the CWA and Section 13263 of the Porter -Cologne Act. Based on a review o f the conceptual site plan, approximately 0.37 acre of impacts to RWQCB jurisdiction (non-wetland WotS) are anticipated, comprised of 0.27 acre of permanent impacts within the project site, and 0.10 acre of temporary impacts within the survey area. Therefo re, it would be necessary for the project proponent to obtain a Waste Discharge Requirement from the RWQCB prior to impacts occurring within RWQCB jurisdictional areas.

Section 3 – Results and Discussion

Habitat Assessment and MSHCP Consistency Analysis

3.8.3 CALIFORNIA DEPARTMENT OF FISH AND WILDLIFE
The CDFW regulates alterations to lakes, streambeds, and riparian habitats pursuant to Section 1600 et seq. of the CFGC. Based on a review of the conceptual site plan, a total of 0.39 acre of impacts to CDFW jurisdiction are anticipated. Anticipated impac ts consist of 0.27 acre of permanent impacts and 0.10 acre of temporary impacts to vegetated streambed, and <0.01 acre of permanent impacts and 0.02 acre of temporary impacts to associated riparian. Therefore, it would be necessary for the project proponen t to obtain a Section 1602 Streambed Alteration Agreement from the CDFW prior to impacts occurring within CDFW jurisdictional areas.

Section 4 MSHCP Consistency Analysis
This section contains the findings of Michael Baker’s MSHCP consistency analysis for the proposed project. The purpose of this consistency analysis is to summarize the biological data for the proposed project and to document the project’s consistency with the goals and objectives of the MSHCP. This analysis is focused on the project site. According to the RCA’s online MSHCP Information Application (RCA 2018), the project site is not located within any Subunits, Criteria Cells, Conservation Areas, Cores/Linkages, or P/QP lands identified by the MSHCP (refer to Figure 6, MSHCP Conservation Areas). However, the project site is located within a designated survey area for BUOW according to the RCA’s online MSHCP Information Application (RCA 2018).

4.1 PROJECT INTRODUCTION AND SETTING

4.1.1 PROJECT AREA
The project site consists of APN 488-190-027, 488- 190-005, and 488-190-028 which is approximately

29.39 acres. As previously stated, according to the RCA’s online MSHCP Information Application (RCA 2018), the project site is located within a designated survey area for BUOW and is not located within any Subunits, Criteria Cells, Conservation Areas, Cores/Linkages, or P/QP lands identified by the MSHCP.

4.1.2 PROJECT DESCRIPTION
The proposed project includes the development of up to 133 residential units, a water basin, a park, and road construction on 29.39 acres (refer to Appendix A, Proposed Site Plan).

4.1.3 COVERED ROADS
The proposed project does not include the construction of, or improvements to, any Covered Roads referenced in Section 7 of the MSHCP. Therefore, a discussion related to the proposed project and Covered Roads is not warranted.

4.1.4 GENERAL SETTING
The project site is located within a moderately developed portion of the City of M oreno Valley, east of Alessandro Boulevard and Nason Street intersection. Natural habitats within the project site have been eliminated due to routine weed abatement activities (i.e., disking, tilling), resulting in heavily disturbed and compacted surface soils. The topography of the project site is generally flat. Land uses in the immediate vicinity of the project site include vacant, residential, and commercial land uses. Vacant, undeveloped land is located to the north, south, and east of the project site, while residential uses are located along the west, northwest, and northeast boundaries of the site. Additionally, commercial uses were currently being built along the western boundary at the time of the field survey.

4.2 RESERVE ASSEMBLY ANALYSIS
According to the RCA’s online MSHCP Information Application (RCA 2018), the project site is not located within any Subunits, Criteria Cells, Conservation Areas, Cores/Linkages, or P/QP lands identified by the MSHCP (refer to Figure 6, MSHCP Conservation Areas). Therefore, a Reserve Assembly discussion related to the proposed project is not warranted.

4.2.1 PUBLIC/QUASI-PUBLIC LANDS ANALYSIS
According to the RCA’s online MSHCP Information Application (RCA 2018), the project site is not located within any P/QP lands identified by the MSHCP. Therefore, a discussion related to P/QP lands and the proposed project is not warranted.

4.3 VEGETATION MAPPING
As stated in Section 6.3.1 of the MSHCP, project-level vegetation mapping may be required for projects that meet certain criteria to assess whether conservation is required . Michael Baker conducted a review of the 2012 vegetation layer presented in the RCA’s online MSHCP Information Application and aerial photography to understand existing site conditions and extent of any disturbances that have occurred on the project site (RCA 2018). In addition, a field survey was conducted in order to document the extent and condition of the vegetation communities occurring within the boundaries of the project site.

Vegetation communities occurring within the project site were delineated on an aerial photograph during the field surveys and later digitized using the GIS ArcView software to quantify the area of each vegetation community in acres. Vegetation communities occurring within the project site were classified in accordance with the vegetation descriptions provided in the Manual of California Vegetation (Sawyer et al., 2009) and cross referenced with the vegetation communities described in the MSHCP and the 2012 vegetation layer presented in the RCA’s online MSHCP Information Application (RCA 2018).

Based on the results of the field survey, natural habitats within the project site have been eliminated due to routine weed abatement activities (i.e., disking, tilling), resulting in heavily disturbed and compacted surface soils. As such, native vegetation communities do not occur. The project site is primarily comprised of disturbed and developed land that is dominated by ruderal/weedy, low -growing plant species and ornamental plant species (refer to Figure 4, Vegetation Communities and Other Land Uses). Based on the 2012 vegetation layer presented in the RCA’s online MSHCP Information Application, the entire project site was mapped as developed/disturbed land (RCA 2018). Refer to Table 3 below for a summary of the vegetation communities and land cover types within the project site and 50-foot survey area.

4.4 PROTECTION OF SPECIES ASSOCIATED WITH RIPARIAN/

RIVERINE RESOURCES AND VERNAL POOLS

4.4.1 RIPARIAN/RIVERINE
As defined under Section 6.1.2 of the MSHCP, riparian/riverine resources are 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. Conservation of these areas is intended to protect habitat that is essential to a wide variety of listed or special-status water- dependent fish, amphibian, avian, and plant species.

As documented in the Delineation of State and Federal Jurisdictional Waters (Michael Baker 2022), t wo (2) drainage features were recorded within the survey area (AF-1 and AF-2). These drainage features qualify as riparian/riverine resources pursuant to Section 6.1.2 of the MSHCP and total approximately 0.27 acre of riverine habitat within the project site (0.37 acre within the entire survey area) and < 0.01 acre of riparian vegetation within the project site (0.02 acre within the entire survey area) consisting primarily of mulefat (refer to Figure 7, Riparian/Riverine Resources). AF-1 and AF-2 are ephemeral and only flow in direct response to precipitation. If impacts to riparian/riverine resources cannot be avoided, a Determination of Biologically Equivalent or Superior Preservation (DBESP) report would need to be prepared and submitted to the RCA and Wildlife Agencies (USFWS and CDFW) for review and approval prior to implementation of the proposed project.

4.4.2 VERNAL POOLS
One of the factors for determining the presence of vernal pools would be demonstrable evidence of seasonal ponding in an area of topographic depression that is not subject to flowing waters. Prior to conducting the habitat assessment, a review of historical aerial photographs using Google Earth was conducted. In addition, a review of the USDA Custom Soil Resource Report for Western Riverside Area , California, was also conducted to determine the soil associations within the project site . The MSHCP lists two general classes of soils known to be associated with special -status plant species and presence of vernal pool habitat; clay soils and Traver -Domino Willow association soils. The specific clay soils known to be associated with special-status species/vernal pool habitat within the MSHCP Plan Area include Bosanko, Auld, Altamont, and Porterville series soils, whereas Traver-Domino Willows association includes saline-alkali soils largely !>

located along floodplain areas of the San Jacinto River and the Salt Creek flood control channel.

Based on a review of the Custom Soil Resource Report for Western Riverside Area, California (USDA 2022), none of the soil classes (e.g., Bosanko, Auld, Altamo nt, and Porterville series and Traver -Domino Willows association) known to be associated with vernal pool habitat occur within the project site . The mapped soils throughout the project site primarily consist of sandy loam textures and not the clay soil textures which are needed to form the impermeable restrictive duripan layer below the soils surface.

Therefore, no direct or indirect impacts are expected to occur, and no further discussion related to the proposed project and vernal pools is warranted.

4.4.3 FAIRY SHRIMP
One species of fairy shrimp has been recorded in the USGS Sunnymead, California 7.5-minute quadrangle:

Riverside fairy shrimp (Streptocephalus woottoni ). Riverside fairy shrimp are restricted to deep seasonal vernal pools, vernal pool like ephemeral ponds, stock ponds , and other human modified depressions that are typically dry a portion of the year, but usually are filled by late fall, winter or spring rains, and may persist through May. In Riverside County, the species been found in pools formed over the following soils:

Murrieta stony clay loams, Las Posas series, Wyman clay loam, and Willows soils. According to the CNDDB, there are t wo (2) occurrence records for Riverside fairy shrimp within the USGS Sunnymead, California 7.5-minute quadrangle. The closest occurrence (Occurrence Number 27) was recorded in 1998, approximately 4-miles southwest of the project site in a complex of pools on March Airforce Base ; Riverside fairy shrimp cysts were found during dry-season survey in 1998 and there were no mature Riverside fairy shrimp during the wet season. However, this occurrence record is now considered extirpated since 2009 (CDFW 2022a).

Based on the results of the vernal pool habitat assessment in the previous section 4.4.2, no vernal pools occur within the project site. In addition, the project site is separated from the closes t extant occurrence record for Riverside fairy shrimp (Occurrence Number 27) by residential and commercial development and highly trafficked roadways. Based on this information, it was determined that there is no suitable habitat for fairy shrimp within or adjacent to the project site and that fairy shrimp are not known to occur anywhere in close proximity to the site. Therefore, no direct or indirect impacts are expected to occur, and no further discussion related to the proposed project and fairy shrimp is warranted.

4.4.4 RIPARIAN BIRDS
Based on the field survey, riparian/riverine resources were not observed within the project site. Therefore, a discussion related to riparian birds (i.e., western yellow-billed cuckoo [Coccyzus americanus occidentalis], southwestern willow flycatcher [Empi donax traillii extimus], least Bell’s vireo [Vireo bellii pusillus]) and the proposed project is not warranted.

4.1 PROTECTION OF NARROW ENDEMIC PLANT SPECIES
According to the RCA’s online MSHCP Information Application (RCA 2018) and Figure 6 -1 of the MSHCP, the proposed project is not located within a designated survey area for Narrow Endemic Plant Species. Therefore, a discussion related to Narrow Endemic Plant Species and the proposed project is not warranted.

4.2 ADDITIONAL SURVEY NEEDS AND PROCEDURES

4.6.1 CRITERIA AREA PLANT SPECIES
Based on a desktop review of the RCA’s online MSHCP Information Application (RCA 2018) and Figure 6-2 of the MSHCP, the proposed project is not located within a designated survey area for Criteria Area plant species. Therefore, a discussion related to the proposed project and any associated Criteria Area plant species is not warranted.

4.6.2 AMPHIBIANS
Based on a desktop review of the RCA’s online MSHCP Information Application (RCA 2018) and Figure 6-3 of the MSHCP, the proposed project is not located within a designated survey area for amphibians.

Therefore, a discussion related to the proposed project and MSHCP amphibian species is not warranted.

4.6.3 BURROWING OWL
According to the RCA’s online MSHCP Information Application (RCA 2018) and Figure 6 -4 of the MSHCP, the proposed project is located within a mapped survey area for BUOW.

Literature Review and Habitat Assessment Results
The BUOW is currently designated as a State SSC and is a fully covered species under the MSHCP . The BUOW is a grassland specialist distributed throughout western North America where it occupies open areas with short vegetation and bare ground within shrub, desert, and grassland environments. BUOWs use a wide variety of arid and semi -arid environments with well -drained, level to gently sloping areas characterized by sparse vegetation and bare ground (Haug and Didiuk, 1993; Dechant et al., 1999). BUOWs are dependent upon the presence of burrowing mammals (e.g., California ground squirrels, coyotes, American badger [ Taxidea taxus ]) whose burrows are used for roosting and nesting. The presence or absence of mammal burrows is often a major factor that limits the presence or absence of BUOW. Where mammal burrows are scarce, BUOWs have been found occupying man -made cavities, such as buried and non-functioning drain pipes, stand-pipes, and dry culverts. BUOWs may also burrow beneath rocks and debris or large, heavy objects such as abandoned cars, concrete blocks, or concrete pads. They also require open vegetation allowing open line -of-sight of the surrounding habitat to forage as well as watch for predators.

Section 4 - MSHCP Consistency Analysis
Sunset Crossing TTM 38443 27
Habitat Assessment and MSHCP Consistency Analysis
According to the CNDDB, there are two (2) occurrence records for BUOW within the USGS Sunnymead, California 7.5-minute quadrangle. The closest extant occurrence (Occurrence Number 65) was recorded in 1980, approximately 2.25 miles south of the project site, where a colony of owls was observed at the Perris Reservoir Recreation Area (CDFW 2022a ). Additionally, another occurrence (Occurrence Number 439) approximately 4 miles to the southwest of the project site has seen continual BUOW use since 1991, with the most recent update being in 2007 (CDFW 2022a). In addition, there are dozens of records of this species in the eBird database, within and just outside of a 5-mile radius from the project site (eBird 2022).

Michael Baker biologists surveyed 100% of the project site during the field survey. No BUOWs, sign (i.e., pellets, feathers, castings, or whitewash), occupied burrows, or remnant burrows were observed. However, the project site is sparsely vegetated with a variety of low-growing plant species that allow for open line - of-sight and foraging opportunities for BUOW. In accordance with the Burrowing Owl Survey Instructions for the Western Riverside Multiple Species Habitat Conservation Plan Area , if BUOW habitat occurs on - site, both focused surveys and pre-construction clearance surveys are required (RCA 2006).

Focused Burrowing Owl Surveys
Michael Baker conducted focused BUOW surveys in April, May, and June 2022 following the MSHCP survey protocol, Burrowing Owl Survey Instructions for the Western Riverside County Multiple Species Habitat Conservation Plan Area (RCA 2006). Surveys were conducted between April 12 and June 28, 2022 on the project site and in suitable habitat in the designated survey a rea within 500 feet. Although suitable burrows were found within the survey area, no BUOW s were detected by Michael Baker and the species was determined to be absent from the project site and its immediate vicinity (refer to Appendix E, Focused Burrowing Owl Survey Report).

Additional Survey and Mitigation Requirements
Although BUOWs were not observed during the focused surveys, the survey area contains suitable burrows and habitat that could become occupied by BUOW s prior to implementation of the proposed project.

Therefore, a pre-construction clearance survey would be required to reconfirm the absence of BUOWs and maintain compliance with the MSHCP, MBTA, and CFGC. In accordance with the MSHCP survey protocol (RCA 2006), the pre-construction clearance survey would need to be conducted by a qualified biologist no more than 30 days prior to initiating any ground disturbing activities to avoid direct take of BUOWs. Once the survey is completed, the qualified biologist should prepare and submit a final report documenting the results of the clearance survey to the City of Moreno Valley for review and file. If no BUOWs or occupied burrows are detected, project activities may begin, and no additional avoidance or minimization measures would be required. However, if an occupied burrow is found within the project impact area during the pre- construction clearance survey, a BUOW avoidance and minimization plan and Determination of Biologically Equivalent or Superior Preservation analysis would need to be prepared and su bmitted to the Wildlife Agencies (CDFW and USFWS) for approval prior to initiating project activities.

4.6.4 MAMMALS
The proposed project is not located within a mapped survey area for mammal species according to the RCA’s online MSHCP Information Application (RCA 2018) and Figure 6-5 of the MSHCP. Therefore, a discussion related to the proposed project and MSHCP mammal species is not warranted.

4.3 INFORMATION ON OTHER SPECIES

4.7.1 DELHI SANDS FLOWER-LOVING FLY
According to the RCA’s online MSHCP Information Application (RCA 2018) and the Custom Soil Resource Report for Western Riverside Area, California (USDA 2022), the project site is not underlain by and does not fall within an area containing Delhi Sand soils. Therefore, no direct or indirect impacts are expected to occur, and no further discussion related to the proposed project and the Delhi Sands flower - loving fly (Rhaphiomidas terminatus abdominalis) is warranted.

4.7.2 SPECIES NOT ADEQUATELY CONSERVED
As described in Section 2.1.4 of the MSHCP, of the one hundred and forty-six (146) Covered Species addressed in the MSHCP, one-hundred and eighteen (118) species are considered to be adequately conserved. The remaining twenty-eight (28) Covered Species will be considered to be adequately conserved when certain conservation requirements are met as identified in the species-specific conservation objectives listed in Table 9-3 of the MSHCP. Based on the current status of covered species not adequately conserved presented in Table 9 -3, the Monitoring Program has collected sufficient data in 2019 to confirm that beautiful hulsea ( Hulsea vestita ssp. callicarpha), Coulter's matilija poppy ( Romneya coulteri ), Fish's milkwort ( Polygala cornuta var. fishiae), graceful tarplant ( Holocarpha virgata ssp. elongata), Parry’s spineflower (Chorizanthe parryi var. parryi), peninsular spine flower (Chorizanthe leptotheca), Plummer's mariposa lily ( Calochortus plummerae ), rainbow manzanita ( Arctostaphylos rainbowensis ), and small- flowered microseris (Microseris douglasii var. platycarpha) met the requirements listed in Table 9-3 of the MSHCP.

None of the species listed in Table 9-3 of the MSHCP were observed within the project site during the field survey. All remaining species listed in Table 9-3 of the MSHCP are not expected to occur within the project site based on existing site conditions and a review of specific habitat requirements, occurrence records, and known distributions.

4.4 GUIDELINES PERTAINING TO THE URBAN/WILDLANDS

INTERFACE
The urban/wildlands interface guidelines presented in Section 6.1.4 of the MSHCP are intended to address indirect effects associated with new development in proximity to MSHCP Conservation Areas. The project site is not located adjacent to any Criteria Cells, Conservation Areas, Cores/Linkages, or P/QP lands Section 4 - MSHCP Consistency Analysis
Sunset Crossing TTM 38443 29
Habitat Assessment and MSHCP Consistency Analysis
identified by the MSHCP. Therefore, a discussion related to the proposed project and the urban/wildlands interface guidelines presented in Section 6.1.4 of the MSHCP is not warranted.

4.5 STANDARD BEST MANAGEMENT PRACTICES
In accordance with Appendix C of the MSHCP, the following standard best management practices (BMPs) should be implemented to reduce project-related impacts:
• A qualified biologist should present to project personnel (including temporary, contractors, and subcontractors) a worker environmental awareness program prior to the initiation of grading activities. Project personnel should be advised on any special -status wildlife species of concern , the steps to avoid impacts to the species and the potential penalties for taking such species. At a minimum, the program should include the following topics: occurrence of the listed and sensitive species in the area, their general ecology, sensitivity o f the species to human activities, legal protection afforded to these species, penalties for violations of federal and State laws, reporting requirements, and project features designed to reduce the impacts to these species and promote continued successful occupation of the project area. Color photographs of the listed species should be included in the program and be shown to personnel . Following the program, the photographs should be posted in the contractor and resident engineer office and remain through the duration of the project. The contractor, resident engineer, and the qualified biologist should be responsible for ensuring that personnel are aware of the listed species. If additional personnel are added to the project after initiation, they should receive instruction prior to working on the project. • In order to avoid or minimize impacts to water quality, a construction Storm Water Pollution Prevention Plan and Soil Erosion and Sedimentation Plan should be developed to minimize erosion and identify specific pollution prevention measures that would eliminate or control potential point and non‐point pollution sources on‐site during and following the project’s construction phase. The project design should incorporate permanent erosion control elements to e nsure that storm water runoff does not cause soil erosion. In addition, erosion control measures sh ould be applied to all exposed areas during construction. Erosion control measures may include the trapping of sediments within the construction area by placing barriers, such as straw bales, at the perimeter of downstream drainage points or by construction of temporary detention basins. Other methods of minimizing erosion impacts include hydromulching and limiting the amount and length of exposure of graded soil.
• Disturbance related to the project should be minimized to the maximum extent possible. Project site access should also be limited to existing disturbed roads and access routes. • Prior to construction, highly visible barriers (e.g., orange construction fencing) should be clearly defined and installed around the perimeter of the project impact area and access routes. • In order to avoid impacts to nesting birds, any native vegetation removal or tree (native or exotic) trimming activities sh ould occur outside of the nesting bird season (February 1 – August 31). If Section 4 - MSHCP Consistency Analysis
Sunset Crossing TTM 38443 30
Habitat Assessment and MSHCP Consistency Analysis
avoidance of the nesting bird season is not feasible, a pre-construction nesting bird clearance survey should be conducted by a qualified biologist no more than three days prior to the start of any vegetation removal or ground disturbing activities to maintain compliance with the MBTA and CFGC and ensure that impacts to nesting birds do not occur. The qualified biologist should survey all suitable nesting habitat within the project impac t area, including areas within a biologically defensible buffer distance surrounding the project impact area, for the presence of nesting birds and should provide documentation of the surveys and findings to the City of Moreno Valley for review prior to in itiating project activities. If no active bird nests are detected, project -related activities may begin. If an active nest is found, the bird should be identified to species and the approximate distance from the closest work site to the active nest should be estimated and the qualified biologist should establish a “no -disturbance” buffer around the active nest. The distance of the “no - disturbance” buffer may be increased or decreased according to the judgement of the qualified biologist depending on the level of activity and species (i.e., listed, sensitive). In addition, the qualified biologist should periodically monitor any active bird nests to determine if project-related activities occurring outside the ‘no disturbance” buffer disturb the birds and if the buffer should be increased. Once the young have fledged and left the nest, or the nest otherwise becomes inactive under natural conditions, project-related activities within the ‘no disturbance” buffer may occur. • All equipment maintenance, staging, and dispensing of fuel, oil, or any other such activities should occur in developed or previously disturbed upland areas so as to prevent the runoff from any spills from entering waters of the U.S., waters of the State, or riparian/riverine resources. All construction equipment should be operated in a manner to prevent accidental damage to nearby preserved areas and any project-related spills of hazardous materials should be immediately reported to appropriate entities.
• Silt fence barriers should be installed around water courses to prevent accidental deposition of fill material in these areas. And brush, loose soils, or other similar debris materials should be stockpiled in developed or disturbed upland areas.
• A qualified biologist should monitor construction for the duration of the project to ensure that BMPs and other avoidance and minimization measures are properly implemented. • Removal of native vegetation should be minimized to the maximum extent possible. • Removal of exotic species that prey upon or displace target species of concern should be removed from the project work area, if possible.
• Trash, construction refuse (e.g., broken equipment parts, cables, etc.), and food items should be contained in closed containers and removed daily.

Habitat Assessment and MSHCP Consistency Analysis
Section 5 Conclusions and Recommendations
The survey area is located within a moderately developed portion of the City of M oreno Valley, north of Bay Avenue, south of Cottonwood Avenue, west of Marion Road, and east of Nason Street. Natural habitats within the survey area have been eliminated due to routine weed abatement activities (i.e., disking, tilling), resulting in heavily disturbed and compacted surface soils. As such, native vegetation communities do not occur. The survey area is primarily comprised of disturbed land that is dominated by ruderal/weedy and ornamental plant species.

No special-status plant species were observed within the survey area during the field survey. Based on the results of the field survey and a review of specific habitat preferences, distributions, and elevation ranges, Michael Baker determined that all special -status plant species identified by the CNDDB, CIRP, and IPaC either have a low potential or are not expected to occur within the survey area.

Cooper’s hawk was the only special-status wildlife species observed during the field survey. Based on the results of the field survey and a review of specific habitat preferences, occurrence records, known distributions, and elevation ranges, it was determined that the survey area has a low potential to support BUOW (a State SSC), California horned lark (a State WL species), western mastiff bat (a State SSC), and western yellow bat (a State SSC). Additionally, although not observed or expected to occur within the survey area, because the survey area is an undeveloped open space, bats may still forage over it if an insect prey base is present, particularly because there is also roosting habitat on-site. All remaining special-status wildlife species identified during the literature review and records s earch are not expected to occur within the survey area.

In addition to the standard BMPs identified in Section 4.9 above, it is recommended that the following Avoidance and Minimization Measures ( AMMs) be implemented to avoid and/or minimize potential impacts to special-status biological resources:

AMM BIO-1: If project -related activities are to be initiated during the nesting season (February 1 to August 31), a pre -construction nesting bird clearance survey shall be conducted by a qualified biologist no more than three (3) days prior to the start of any vegetation removal or ground disturbing activities. The qualified biologist shall survey all suitable nesting habitat within the project impact area, and areas within a biologically defensible buffer zone surrounding the project impact area. If no active bird nests are detected during the clearance survey, project activities may begin, and no additional avoidance and minimization measures shall be required. If an active bird nest is found, the species shall be identified, and a “no-disturbance” buffer shall be established around the active nest. The size of the “no-disturbance” buffer shall be increased or decreased based on the judgment of the qualified biologist and level of activity and sensitivity of the species. The qualified biologist shall periodically monitor any active bird nests to determine if project-related activities occurring outside the “no -disturbance” buffer disturb the birds and if the buffer shall be increased. Once the young have fledged and left the nest, or the nest otherwise Section 5 – Conclusions and Recommendations
Sunset Crossing TTM 38443 32
Habitat Assessment and MSHCP Consistency Analysis
becomes inactive under natural conditions, project activities within the “no -disturbance” buffer may occur following an additional survey by the qualif ied biologist to search for any new bird nests in the restricted area.

AMM BIO-2: No less than 60 days prior to initiating project activities, a qualified bat biologist shall conduct a bat roosting habitat suitability assessment of any vegetation that m ay be removed, altered, or indirectly impacted by the project activities. Any locations identified as having potentially suitable bat roosting habitat by the qualified approved bat biologist shall be subject to additional nighttime surveys (bat surveys) durin g the summer months (i.e., June through August) to determine the numbers and bat species using the roost(s).

The information collected during these additional bat surveys shall be used by the qualified bat biologist to develop species -specific measures to minimize impacts to roosting bats should bats be detected using the site. The bat surveys shall be conducted by the qualified bat biologist using an appropriate combination of visual inspection, sampling, exit counts, and acoustic surveys. The results of the pre-construction bat surveys shall be submitted to CDFW for review no less than 30 days prior to the initiation of project activities.

If the presence of bats within the project is confirmed, avoidance and minimization measures, including the designation of buffers based upon the particular bat species found and phased removal of trees, shall be developed and submitted to CDFW for review and approval. If the site supports maternity roosts, the project applicant shall avoid disturbing those areas during the breeding season.

If the site supports a maternity roost(s) or special-status species, the project applicant shall contact CDFW and conduct an impact assessment prior to commencing project activities to assist in the development of minimization and mitig ation measures. The project applicant shall compensate for impacts and losses to maternity roosts and/or special-status bat habitat through a mitigation strategy approved by CDFW.

AMM BIO-3: A pre-construction clearance survey would be required to reconfirm the absence of BUOW within the project impact area and maintain compliance with the MSHCP, MBTA, and CFGC. In accordance with the MSHCP, the pre-construction clearance survey would need to be conducted by a qualified biologist no more than 30 days prior to initiating any ground disturbing activities to avoid direct take of BUOWs. Once the survey is completed, the qualified biologist should prepare and submit a final report documenting the results of the clearance survey to the City of Moreno Valley for review and file. If no BUOWs or occupied burrows are detected, project activities may begin, and no additional avoidance or minimization measures would be required. However, if an occupied burrow is found within the project impact area during the clearance survey, a DBESP report outlining specific avoidance, minimization, and compensatory mitigation methods that will be implemented to avoid impacts to BUOW would need to be prepared and submitted to the Wildlife Agencies (CDFW and USFWS) for approval prior to initiating project activities.

Section 5 – Conclusions and Recommendations
Sunset Crossing TTM 38443 33
Habitat Assessment and MSHCP Consistency Analysis
No evidence of hydrology or vernal pool indicator plant species were observed during the field survey.

Based on a review of the Custom Soil Resource Report for Western Riverside Area, California (USDA 2022), none of the soil classes (e.g., Bosanko, Auld, Altamont, and Porterville series and Traver -Domino Willows association) known to be associated with vernal pool habitat occur within the survey area. The mapped soils throughout the survey area primarily consist of sandy loam textures and not the clay soil textures which are needed to form the impermeable restrictive duripan layer below the soils surface.

Therefore, no direct or indirect impacts are expected to occur to vernal pools.

Based on the results of the vernal pool habitat assessment, no vernal pools are expected to occur within the survey area. In addition, the survey area is separated from extant populations of Riverside fairy shrimp known to occur in the surrounding area by residential and commercial development, I-215, and other highly trafficked roadways. Therefore, no direct or indirect impacts are expected to occur to Riverside fairy shrimp.

Two (2) drainage features (AF -1 and AF-2) occur within the survey area and would fall under regulatory authority of the RWQCB and CDFW. Based on a review of the conceptual site plan, approximately 0.37 acre of impacts to RWQCB jurisdiction (non-wetland WotS) are anticipated, comprised of 0.27 acre of permanent impacts within the project site and 0.10 acre of t emporary impacts within the survey area, as well as a total of 0.39 acre of impacts to CDFW jurisdiction consisting of 0.27 acre of permanent impacts and 0.10 acre of temporary impacts to vegetated streambed, and <0.01 acre of permanent impacts and 0.02 acre of temporary impacts to associated riparian.. It is anticipated that the project proponent would need to obtain the following regulatory permits prior to impacts occurring within jurisdictional areas: 1) Waste Discharge Requirement from the RWQCB , and 2 ) Section 1602 Streambed Alteration Agreement from CDFW.

AF-1 and AF -2 would qualify as riparian/riverine resource s pursuant to Section 6.1.2 of the MSHCP; a total of approximately 0.37 acre of riverine habitat and 0.02 acre of riparian habitat occur within the project site. Riparian/riverine resources within the survey area do not provide suitable habitat for western yellow- billed cuckoo, southwestern willow flycatcher, least Bell’s vireo , or fairy shrimp, and vernal pools are not present. If impacts to riparian/riverine resources cannot be avoided, a DBESP report would need to be prepared and submitted to the RCA and Wildlife Agencies (USFWS and CDFW) for review and approval prior to implementation of the proposed project.

* Non-native species
** California Invasive Plant Council (Cal-IPC) Ratings
High These species have severe ecological impacts on physical processes, plant and animal communities, and vegetation structure. Their reproductive biology and other attributes are conducive to moderate to high rates of dispersal and establishment. Most are widely distributed ecologically.

Moderate These species have substantial and apparent —but generally not severe —ecological impacts on physical processes, plant and animal communities, and vegetation structure. Their reproductive biology and other attributes are conducive to moderate to high rates of dispersal, though establishment is generally dependent upon ecological disturbance. Ecological amplitude and distribution may range from limited to widespread.

Limited These species are invasive but their ecological impacts are minor on a statewide level or there was not enough information to justify a higher score. Their reproductive biology and other attributes result in low to moderate rates of invasiveness. Ecological amplitude and distribution are generally limited, but these species may be locally persistent and problematic.

Watch These species have been assessed as posing a high risk of becoming invasive in the future in California. *** Special-Status Rank

Appendix E Focused Burrowing Owl Survey Report

HIGHPOINTE COMMUNITIES

530 Technology Dr, #100
Irvine, California 92618
SUBJECT: Results of Focused Burrowing Owl (Athene cunicularia) Surveys for Sunset Crossing TTM 38443 – City of Moreno Valley, Riverside County, California Dear Mr. Yamaguchi:

This report contains the findings of Michael Baker International’s (Michael Baker) focused burrowing owl (Athene cunicularia; [BUOW]) surveys conducted during the 202 2 breeding season for Sunset Crossing TTM 38443 (project) located in the City of Moreno Valley, Riverside County, California. Based on the results of Michael Baker’s initial review of California Natural Diversity Database RareFind 5 (CDFW 2022) occurrence records, the project site is located within an area that is or was previously known to be occupied by BUOW and likely provides suitable nesting and foraging habitat . As such, focused BUOW surveys were conducted in accordance with the Burrowing O wl Survey Instructions for the Western Riverside Multiple Species Habitat Conservation Plan Area (RCA 2006). The focused BUOW survey s were conducted on four (4) separate days during the 202 2 breeding season to document the presence/absence of BUOW within the project site and areas of suitable habitat within 500 feet ( survey area).

Project Location
The project site is located within the City of Moreno Valley, generally to the north of Perris Reservoir, east of Interstate 215 (I-215), south of State Route 60 (SR-60), and west of SR-79 (refer to Figure 1, Regional and Project Vicinity, in Attachment A). The project site is depicted in Section 10, Township 3 South, Range 3 West, on the United States Geological Survey’s (USGS) Sunnymead, California 7.5-minute quadrangle.

Specifically, the project site is located north of Bay Avenue, east of Nason Street , south of Cottonwood Avenue, and west of Marion Road, on assessor’s parcel numbers (APN) 488 -190-027, 488-190-005, and 488-190-028.

Project Description
The proposed project includes the development of up to 133 residential units, a water basin, a park, and road construction on 29.39 acres.

Sunset Crossing TTM 38443 2
Focused Burrowing Owl Survey Report
Background
Burrowing Owl
The BUOW is a grassland specialist distributed throughout western North America, where it is known to occupy a wide variety of arid and semi -arid open areas within shrub, desert, and grassland environments.

The California Department of Fish and Wildlife (CDFW) currently lists the BUOW as a California Species of Special Concern. BUOWs require large open, sparsely vegetated areas, on rolling or level terrain with an abundance of fossorial mammal burrows (> 4 inches in diameter). In addition, BUOWs require low- growing vegetation allowing line -of-sight of the surrounding habitat to forage as well as watch for predators. BUOWs are dependent upon the presence of burrowing mammals (e.g., California ground squirrel [ Otospermophilus beecheyi], coyote [ Canis latrans], American badger [ Taxidea taxus ]) whose burrows are used for roosting and nesting (Haug et al. 1993). The presence or absence of fossorial mammal burrows is often a major factor that limits the presence or absence of BUOW. Where mammal burrows are scarce, BUOWs have been observed digging their own burrows in soft, friable soil and have been observed utilizing man-made cavities such as buried and non-functioning drain pipes, stand-pipes, and dry culverts.

Additionally, BUOWs may burrow beneath rocks and debris or large, heavy objects such as abandoned cars, concrete blocks, or concrete pads. Large, hard objects at burrow entrances stabilize the entrance from collapse and may inhibit excavation by predators.

Adult BUOWs are small owls (approximately 7.5 to 9.8 inches) with long legs and short tails that are speckled brown and white, with yellow eyes and a yellow bill. A bold white throat and eyebrows are also typical distinguishing features for BUOWs. Juvenile BUOWs are usually less mottled than adults, with buffy-yellow underparts. BUOWs have crepuscular (dawn and dusk) hunting habits but are often observed perched in or near the burrow entrance during the day. One burrow is typically selected for use as the main nest burrow, however, BUOWs also utilize satellite burrows that are often located within the immediate vicinity of the main nest burrow. BUOWs prey upon invertebrates and small vertebrates through the low growing vegetation which allows for foraging visibility (Thomsen 1971). They typically forage in short - grass, mowed, or overgrazed pasture, golf courses and airports (Thomsen 1971). Based on the Staff Report on Burrowing Owl Mitigation (CDFG 2012), the BUOW breeding season in California extends from February 1 through August 31 . BUOWs in California may migrate southerly, but often remain in their breeding area during the non -breeding months. The BUOW was once abundant and widely distributed within southern California, but it has declined precipitously in counties such as Los Angeles, Orange, San Diego, Riverside, and San Bernardino.

Regulatory Framework
The BUOW is a resident and migratory bird species protected by international treaty under the Migratory Bird Treaty Act (MBTA) of 1918. The MBTA reflects agreements made between the U.S., England, Mexico, the former Soviet Union, and Japan to protect all of North America’s migratory bird populations.

The MBTA protects migratory bird nests from possession, sale, purchase, barter, transport, import and export, and collection. The other prohibitions (i.e., capture, pursue, hunt, and kill) of the MBTA are inapplicable to nests. The regulatory definition of take, as defined in Title 50 Code of Federal Regulations (C.F.R.) Part 10.12, means to pursue, hunt, shoot, wound, kill, trap, capture, or collect, or attempt to hunt, shoot, wound, kill, trap, capture, or collect. Only the verb “collect” applies to nests. It is illegal to collect, possess, and by any means transfer possession of any migratory bird nest. The MBTA prohibits the

Sunset Crossing TTM 38443 3
Focused Burrowing Owl Survey Report
destruction of a nest when it contains birds or eggs, and no possession shall occur d uring the destruction (U.S. Fish and Wildlife Service 2017). Certain exceptions to this prohibition are included in Title 50 C.F.R.

Section 21. Pursuant to Section 3513 of the California Fish and Game Code (CFGC), CDFW enforces the MBTA consistent with rules and regulations adopted by the Secretary of the Interior under provisions of the MBTA.

Additionally, BUOW is protected under Sections 3503, 3503.3, 3511, and 3513 of the CFGC which prohibit the take, possession, or destruction of birds, their nests or eggs. Implementation of the take provisions requires that project-related disturbance at active nesting territories be reduced or eliminated during critical phases of the nesting cycle (March 1 - August 15, annually). Section 3503.5 of the CFGC protects birds in the orders Falconiformes or Strigiformes (birds of prey, such as hawks and owls, including BUOWs) which makes it unlawful to take, possess, or destroy their nest or eggs.

The Staff Report on Burrowing Owl Mitigation (CDFG 2012) offers long-term assurances for conservation of t his species in exchange for biologically appropriate levels of incidental take and/or habitat loss as defined in the approved plan. California’s Natural Community Conservation Plan (NCCP) Act (CFGC §2800 et seq .) governs such plans at the state level, and was designed to conserve species, natural communities, ecosystems, and ecological processes across a jurisdiction or a collection of jurisdictions.

Complementary Habitat Conservation Plans (HCPs) are governed by the federal endangered Species Act (7 U.S.C. § 136, 16 U.S.C.§ 1531 et seq.). Regional conservation plans (and certain other landscape-level conservation and management plans) may provide conservation for unlisted as well as listed species.

Because the geographic scope of NCCPs and HCPs may span many hundreds of thousands of acres, these planning tools have the potential to play a significant role in conservation of BUOWs.

BUOWs have been included as one of the one hundred and forty -six (146) focal species covered by the Western Riverside County Multiple Species Habitat Conservation Plan ( MSHCP). The objectives for BUOWs within the MSHCP are to maintain and ensure the conservation of occupied burrows on current conserved lands, decrease harmful effects to BUOWs, and identify and implement m onitoring and management to sustain the BUOW population within the MSHCP. BUOWs can be found in a variety of habitats within the MSHCP, predominantly on open land, including grassland, agriculture (e.g., dry -land farming and grazing areas), playa, and spar se coastal sage scrub and desert scrub habitats. Within the MSHCP, BUOWs are narrowly distributed at relatively few locations where suitable habitat is present.

Methodology
As documented in the Habitat Assessment and Western Riverside County Multiple Speci es Habitat Conservation Plan Consistency Analysis (Michael Baker 202 2), the project site is located within a designated survey area for BUOW as identified in the MSHCP and also provides suitable habitat and foraging opportunities for BUOW. As such, focused BUOW surveys were conducted by qualified biologists Lauren Mapes, Ryan Winkleman, April Nakagawa, and Tom Millington on four (4) separate days during the 2022 breeding season: April 12, May 31, June 14, and June 28, 2022. Please refer to Table 1 below for a summary of the survey dates, timing, surveyors, and weather conditions for each of the surveys.

Areas providing suitable habitat for BUOWs within the survey area were surveyed for suitable, occupied, and remnant burrows consisting of natural and non -natural substrates (refer to Figure 2, Survey Area, in Attachment A). Survey transects were conducted at 10-meter (approximately 33 feet) intervals to ensure 100% visual coverage of al l areas in suitable habitat, as applicable based on -site topography, and access.

Binoculars were used to scan areas that were inaccessible due to lack of right -of-entry to observe and identify distant birds; identify any suitable, occupied, and remnant burrows consisting of natural and non- natural substrates ; and search for any activity around suitable BUOW habitat. Methods to detect the presence of BUOWs included direct observation, aural detection, and signs of presence (i.e., pellets, white wash, feathers, or prey remains). The location of all suitable habitat, potential burrows, sign, and BUOWs observed within the survey area were recorded and mapped with a hand -held Global Positioning System (GPS) unit . Surveys were not conducted during rain, high winds, dense fog, or high temperatures. All BUOW focused surveys were conducted between morning civil twilight and 1000 hours.

Results
Existing Conditions
After a review of Google Earth historic imagery and results from the field survey, it was determined that the survey area is comprised of developed land and areas of disturbed habitat and bare ground which consist of heavily disturbed/compacted soils. Google Earth historic imagery from 19 85 through 2021 also shows that the survey area has continually been exposed to disturbances due to routine weed abatement activities (i.e., disking, tilling) throughout the undeveloped portions of the survey area and that these activities have eliminated any natural vegetation communities. Vacant land is present in patches to the north, south, and east of the survey area. Residential land use is located along the west, northwest, and northeast boundary of the survey area. Additionally, commercial uses were currently being built along the western boundary of the project site at the time of the surveys. Please refer to Attachment B for representative photographs taken throughout the survey area.

Regional Context
According to the CNDDB, there are twenty-two (22) occurrence records for burrowing owl within the USGS El Casco, Perris, Riverside East, Steele Peak, and Sunnymead, California 7.5-minute quadrangles, which constitute the quadrangles within a 5-mile radius of the survey area . The closest extant occurrence

Sunset Crossing TTM 38443 5
Focused Burrowing Owl Survey Report
(Occurrence Number 65) was recorded in 1980, approximately 2.25 miles south of the project site where a colony of owls was observed at the Perris Reservoir Recreation Area (CDFW 2022). Additionally, another occurrence (Occurrence Number 439) approximately 4 miles to the southwest of the project site has seen continual BUOW use since 1991, with the most recent update being in 2007 (CDFW 2022). In addition, there are dozens of records of this species in the eBird database, within and just outside of a 5 -mile radius from the project site (eBird 2022).

Focused Survey Results
No BUOWs or BUOW sign (i.e., pellets, white wash, feathers, or prey remains) were observed during any of the four (4) focused surveys. Suitable foraging habitat and line of site opportunities were observed throughout the survey area, as well as suitable burrows (> 4 inches in diameter) capable of providing roosting and nesting opportunities for BUOW. Most burrows observed were located within the southern portions of the 500-foot buffer area and consisted of small mammal burrows < 4 inches in dia meter (refer to Figure 2, Survey Area, in Appendix A). The existing telephone poles, light posts, fencing, and residential and commercial land use that occur within the survey area decrease the likelihood that BUOWs would occur as these features provide perching opportunities for larger raptor species (i.e., red-tailed hawk [Buteo jamaicensis]) that prey on BUOWs. Further, between the third and fourth survey an unknown entity conducted disking/weed abatement activities on -site, which removed much of the non -native vegetation that was present during the first three surveys.

Common bird species detected during the focused surveys included common raven (Corvus corax), house finch ( Haemorhous mexicanus ), northern mockingbird ( Mimus polyglottos ), house sparrow ( Passer domesticus), Say’s phoebe (Sayornis saya), western meadowlark (Sturnella neglecta), and white-crowned sparrow ( Zonotrichia leucophrys). Please refer to Attachment C for a complete list of wildlife species observed during the surveys.

Conclusions and Recommendations
No BUOWs, BUOW sign, occupied BUOW burrows, or remnant BUOW burrows were observed on or within the vicinity of the survey area. Therefore, project-related activities are not expected to result in any direct or indirect impacts to BUOWs or occupied BUOW burrows on or within the vicinity of the survey area.

Although BUOWs were not observed during the focused survey s, the survey area does contain suitable foraging and nesting habitat for BUOW. Due to the presence of suitable foraging habitat for BUOW and the proximity of the survey area to existing occurrence records for BUOW, in accordance with the Burrowing Owl Survey Instructions for the Western Riverside Multiple Species Habitat Conservation Plan Area (RCA 2006), one (1) pre-construction clearance survey should be conducted no more than thirty (30) days prior to any ground disturbing activities to avoid direct take of BUOWs. The clearance survey shall be conducted by a qualified biologist and cover all suitable habitat within the project impact area, including adjacent suitable habitat within a 500 -foot buffer (as accessible). Following completion of the clearance survey, the qualified biologist shall prepare and submit a final report documenting the methods and results of the survey. If no BUOWs or occupied burrows are detected, project activities may begin, and no additional avoidance and minimization measures would be required. If an occupied burrow is found within the project impact area during pre -construction clearance surveys, a BUOW exclusion plan shall be

prepared and submitted to the RCA and Wildlife Agencies (USFWS and CDFW) for approval prior to initiating project activities that includes proposed mitigation for direct and permanent impacts to nesting, occupied, and satellite burrows and/or BUOW habitat.
