1.0) EXECUTIVE SUMMARY
The proposed Project is division of a ±5.74-acre parcel into four (4) lots and construction of a single-family home on each of three (3) of those lots. No grading work is proposed on the open space easement. The fuel modification zone extends into the open space easement and this area is subject to ongoing impacts. Permanent impacts consist of 2.70 acres (including the fuel modification zone) and there are no temporary or offsite impacts.
The Project site consists of APN 243-230-027 (APN 243-600-025 on RCA MSHCP Information Map, located at 841 Alpine Meadows Lane in the Alessandro Heights area of the City of Riverside.
The site is l ocated within the area covered by the Western Riverside County Multiple Species Habitat Conservation Plan ( MSHCP) but is not within the Criteria Area. Public/Quasi-Public (PQP) Conserved Lands identified as Alessandro Arroyo Big Bend are one mile to the east of the site. There are no other PQP or MSHCP Conserved Lands within a mile of the site. The site is not within or near any MSHCP Core Areas or Linkages. Areas of Lots 2 through 4 outside the grading footprint will be an open space easement.
Surveys required by the MSHCP are a habitat assessment to address riparian/riverine and vernal pool habitats and associated species and burrowing owl (Athene cunicularia). If suitable habitat is present, focused surveys are required.
Vegetation on the site consists of disturbed/developed/ornamental areas and coastal scrub.
There is no riparian or Riversidean alluvial sage scrub habitat present. A total of 0. 72 acre of native habitat (distur bed brittlebush scrub) will be impacted by grading and fuel modification .
Brittlebush scrub is not a sensitive vegetation community and no mitigation is proposed for this impact. An ephemeral drainage runs through the southeast portion of the site and a jurisdictional delineation found 0.46 acre of MSHCP riverine habitat present. Ba sed on current Project plans (TPM 38174), this drainage will be avoided.
No state or federally listed or special status plants were identified on the site during the survey .
Listed and special status plants known from the region are either absent, not expected to occur, or have a low potential for occurrence onsite, except Payson’s jewelflower (Caulanthus simulans).
This species is covered under the MSHCP and considered adequately conserved. No mitigation is proposed for any potential impacts to this species.
There are a number of non-native and ornamental trees on the site. The only native trees onsite are blue elderberry (Sambucus nigra ssp. cerulea) and one black willow (Salix gooddingii) with its MSHCP Consistency Analysis

trunk offsite but a portion of its canopy extending over the site boundary and into the open space easement area. There are no oak species present.
No vernal pools or ponding areas were observed and there is no habitat for fairy shrimp . There is no habitat for riparian birds on the site, but potentially suitable habitat is present i n adjacent areas of Prenda Creek. The grading areas on the Project site (plus a 20-foot buffer) are at least 300 feet away from the suitable riparian habitat in Prenda Creek. However, impacts to riparian birds are possible (i.e., noise and disturbance) if the Project grading plans are revised and will encroach within a 300-foot buffer of the riparian habitat in Prenda Creek to the south of the Project site. If this occurs , proposed mitigation requires either avoidance of the nesting season or a habitat assessment and a protocol survey if suitable habitat is present. If a protocol survey finds any of these species present within 300 feet of the Project disturbance area, additional avoidance and minimization measures are required.
A protocol breeding season burrowing owl survey found no owls or owl sign, but suitable habitat is present and a preconstruction clearance survey will be required within 30 days prior to the start of ground/vegetation disturbance. If burrowing owl is found at that time, additional mitigation will be required in accordance with MSHCP species objectives.
Three (3) special status wildlife species were observed during the survey, Cooper’s hawk (Accipiter cooperii ), San Diego desert woodrat (middens) (Neotoma lepida intermedia ), and Nuttall’s woodpecker ( Dryobates nuttalli). Cooper’s hawk and San Diego desert woodrat are covered species under the MSHCP and considered adequately conserved. Nuttall’s woodpecker is not a covered species. Recommended mitigation includes avoidance of Project impacts during the nesting season (February 1 to August 31) or implementation of preconstruction nesting bird clearance surveys and avoidance buffers for active nests.
Most listed and special status wildlife species known from the region are absent, not expected to occur, or have a low potential for occurrence . Several species have a higher potential to occur and these are covered under the MSHCP and considered adequately conserved, with the exception of Crotch bumble bee ( Bombus crotchii), Southern California legless lizard ( Anniella stebbinsi), Allen’s hummingbird (Selasphorus sasin), pallid bat (Antrozous pallidus), and western mastiff bat (Eumops perotis californicus ). These five (5) species are not covered under the MSHCP.
Prenda Creek is adjacent to the Project and may function as a wildlife corridor for limited local travel between currently undeveloped (but not conserved) areas to the east a nd west. The MSHCP Consistency Analysis

drainage running through the site may contribute to this limited movement through the area. The site is not within or near any MSHCP Core Areas or Linkages.
An ephemeral drainage that is tributary to Prenda Creek crosses the southeast port ion of the parcel. This unnamed drainage is not a blueline stream. A jurisdictional delineation found 0.46 acre of MSHCP riverine habitat and no MSHCP riparian habitat on the parcel. The proposed Project will avoid the drainage.
Full text of Mitigation Measure BIO-1 (Burrowing Owl) is provided in Section 7.3.4. Mitigation Measures BIO-2 (Nesting Birds) and BIO -3 (Crotch Bumble Bee) are provided in Section 8.3.
Mitigation Measure BIO-4 (Riparian Birds) is provided in Section 5.4.4. With implementation of recommended mitigations, the Project would be consistent with the MSHCP.

2.0) INTRODUCTION
The purpose of this Consistency Analysis is to summarize the biological data for the proposed Alpine Meadows Estates Project (Project) and to document the Project’s consistency with the goals and objectives of the Western Riverside County Multiple Species Habitat Conservation Plan (MSHCP) (Dudek 2003). The proposed project consists of division of a single parcel into four (4) lots and construction of a single-family home on each of three (3) of those lots. No grading work is proposed within the proposed open space easement but the fuel modification zone extends into the easement.
2.1) Project Area
The Project site consists of APN 243-230-027 (APN 243-600-025 on RCA MSHCP Information Map) totaling ±5.74 acres. Tentative Parcel Map (TPM) 38174 is provided in Appendix B. No offsite areas are included in the Project.
As shown on TPM 38174, an existing residence is present on the westernmost lot (Lot 1) and will remain. No additional impacts are proposed to Lot 1 except the road dedication area . Areas outside of the grading footprint on Lots 2 through 4 will be an open space easement.
Based on the TPM and information provided by the Project proponent, net acreage for Lots 1, 2, and 3 is 1.07 acres each and Lot 4 is 2.14 acres. Net acreage does not include the road dedication area along the northern edge of the parcel.
Based on the grading limits as shown on the TPM plus the fuel modification zone, the total impact area would be 2. 70 acres. The impact area consists of 1. 99 acres of disturbed/developed/ornamental areas and 0.72 acre of brittlebush scrub. No temporary impact areas are proposed and all impacts would be permanent.
An ephemeral streambed (not a blueline) runs through the southeastern portion of the parcel and includes 0.46 acre of MSHCP riverine habitat. The TPM shows that there would be no grading impacts to this streambed.
2.2) Project Description
The Project is a residential development of three (3) single-family homes. Grading will occur on the northern portions of Lots 2 through 4. No detention basins or other water quality features are proposed. The existing residence on Lot 1 will remain and no impacts to Lot 1 are proposed other MSHCP Consistency Analysis

than the road dedication area. Areas outside of the grading footprint on Lots 2 through 4 will be placed in an open space easement.
2.3) Covered Roads
The Project site is adjacent to Alpine Meadows Lane and a portion of the parcel is reserved for road dedication. Alpine Meadows Lane is not a covered road under the MSHCP and the Project does not involve construction or improvement of any covered roads.
2.4) Covered Public Access Activities
The Project does not involve construction or improvement of any covered public access activities.
2.5) General Setting
The property is generally located southeast of the 91 Freeway and north of Van Buren Boulevard in the City of Riverside, Riverside County, California (Figure 1). The site is located at 841 Alpine Meadows Lane in the Alessandro Heights area of the City of Riverside, just southwest of the intersection of Alpine Meadows Lane and Kingdom Drive and about 0.3 mile east of and upstream from the Prenda Dam. The site is with in Section 13 of Township 3 South, Range 5 West, as shown on the USGS Riverside East 7.5' topographic quadrangle (Figure 2).
The site is generally bounded as follows: to the west by a residential property and Harbart Drive, with Prenda Dam, a blueline stream (Prenda Creek), a mixture of vacant lots, undisturbed lands, residential subdivisions, and Washington Street beyond; to the north by Alpine Meadows Lane, a blueline stream (unnamed), and a mixture of residential developments, vacant lots , and undisturbed lands, with the 91 Freeway and the City of Riverside beyond; to the east by Kingdom Drive and a mixture of residential developments, vacant lots , and undisturbed lands, with Trautwein Road beyond; and to the south by disturbed vacant lands, Prenda Creek , and residential developments, with additional disturbed and undisturbed vacant lands, residential and commercial developments, and Van Buren Boulevard beyond.
The western portion of the site is developed and contains a single-family residence with detached garage and irrigated landscaping that includes a grass lawn and ornamental trees, shrubs, and flowers. The residence was unoccupied during the surveys but the onsite ornamental landscaping was generally well-maintained. There is a row of ornamental trees on the northern site boundary along Alpine Meadows Lane. Two wells are present on the site, one in the northeast quadrant and a second on the south-central portion of the site. The wells are approximately 345 feet apart MSHCP Consistency Analysis

QUIN-05-R752.CD1 (final).rev4 clean 9 L&L
at either end of an onsite unimproved dirt road. The entire site perimeter is fenced with rail fencing, chain link, or barbed wire.
The western and north -central areas of the site have been cleared and have virtu ally no vegetation. Native vegetation is present in the east, southeast, and south-central portions of the site and consists of coastal scrub , specifically brittlebush scrub (Encelia farinosa Shrubland Alliance). Several rock piles are present on the northeastern corner of the site, including concrete debris.
The project is located within the Santa Ana River watershed in Riverside County and more specifically in the City of Riverside. An unnamed ephemeral streambed (not a blueline stream) runs through the southeast portion of the site from east to west. There has been disturbance to the drainage, particularly on the west end. On the east end, vegetation in and along the drainage is brittlebush scrub. On the west end, it is either unvegetated or non-native and ruderal. The only riparian vegetation is one native willow tree. The trunk of this willow is offsite but a portion of its canopy overhangs the eastern site boundary.
The onsite stream is tributary to Prenda Creek, a blueline stream that is about 150 feet south of the site. A second blueline stream (unnamed) is about 350 feet north of the site and converges with Prenda Creek at the Prenda Dam, about 0.3 mile west and downstream of the site. Most of the site is within the mapped extent of the Prenda Arroyo (Figure 4).
The northwestern portion of the site and the southeast ern corner are relatively flat, sloping downward to the drainage running through the site. The elevation onsite ranges from 1279 feet (390 meters) above mean sea level (AMSL) in the southwest corner to 1334 feet (407 meters) AMSL in the northeast corner.
Soils onsite are mapped as Buren fine sandy loam (BuD2), Cieneba rocky sandy loam (CkF2), Hanford coarse sandy loam (HcC), and terrace escarpments (TeG) (NRCS 2021) (Figure 5).
Precipitation data was obtained from the Clark and Lake Mathews Remote Automated Weather Stations (RAWS) (WRCC 2021). The Clark RAWS is located about 4.0 miles southeast of the Project site at an elevation of 1,720 feet and the Lake Mathews RAWS is about 8.6 miles southwest of the site at an elevation of 1,516 feet (WRCC 2021).
Tables 1a and 1b provide precipitation da ta from the Clark and Lake Mathews RAWS, respectively, from October 2018 through July 2021 (WRCC 2021). Total precipitation recorded by the Clark RAWS for the 2019 water year (October 2018 through September 2019) was 12.92 MSHCP Consistency Analysis

4.0) VEGETATION MAPPING
4.1) Methods
Vegetation mapping was conducted during a biological resources assessment survey conducted by L&L biologist Guy Bruyea. Mr. Bruyea visited the Project site during June and July of 2021 to describe vegetation and habitat and evaluate the site for presence of suitable habitat for special status plant and wildlife species (Table 2). A protocol breeding season burrowing owl survey was conducted concurrently (see Section 7.3).
Table 2. Survey dates, times, and weather conditions.

*sunrise times from www.timeanddate.com
A total of about 6.5 person-hours were spent onsite. All habitat types onsite were visited on foot.
The site was surveyed by conducting a series of meandering transects across the subject property where possible, stopping periodically for observations and notations. A general habitat map and field notes were completed during the survey . All field surveys were conducted during daylight hours. Digital photographs were taken to record site conditions during the survey.
Plants of uncertain identity were collected and subsequently identified from keys, descriptions, and illustrations in Abrams (1923, 1944, and 1951), Abrams and Ferris (1960), Munz (1974), and Parker (1999).
Pertinent literature was reviewed to identify local occurrences and habitat requirements of special status species and communities occurring in the region. Literature reviewed included compendia provided by resource agencies (CDFW 2021a, 2021b), a search of the California Natural Diversity Database (CNDDB; CDFW 2021c) and California Native Plant Society Inventory of Rare and Endangered Plants (CNPS 2021) for the Project topographic quadrangle ( Riverside East) and adjacent quadrangles (Fontana, San Bernardino South, Redlands, Riverside West, Sunnymead, Lake Mathews, Steele Peak, and Perris), and a search of USFWS Information for Planning and Consultation (IPAC; USFWS 2021) for the Project site.

Potentials for occurrence of plant and wildlife species were evaluated and classified as either absent, not expected, low, moderate, high, or occurs. These classifications are based on the presence and quality of habitat, geographic and elevation range of species, proximity to a known occurrence of a species obtained from CNDDB or other reliable data, and field observations.

In this report, the “site” or “property” refers to the entire ±5.74-acre parcel.
L&L also conducted a biological survey of the site in 2006 (L&L 2006a) and a s ummary of that information is included in this report as appropriate. The 2006 survey consisted of one site visit on August 17, 2006. In this report, the “survey” refers to the 2021 survey unless the 2006 survey is specifically stated.
4.2) Existing Conditions and Results
The site, particularly the western portion, has been disturbed for residential use since 1947 (L&L 2006b). A review of historical aerial images finds that the entire parcel appears to have been completely cleared of vegetation in 1978 but vegetation had reestablished by 1994 (NETRonline 2021). The cleared area currently present in the western and north-central areas of the site is first apparent in 2004 (Google Earth 2021) although it increases in size over time. The road between the wells is also first visible in 2004.
The site is currently occupied by developed areas and ornamental vegetation associated with the residence, disturbed/ruderal areas, and disturbed an d relatively undisturbed brittlebush scrub (Table 3 and Figures 7a and 7b).
An unnamed ephemeral streambed crosses through the southeastern portion of the site.
A mature black willow (Salix gooddingii) is present within the streambed and its trunk is just offsite at the east-central fence line. A portion of t his willow’s canopy extends over the site boundary MSHCP Consistency Analysis

but no native riparian or wetland vegetation is present on the site. On the east end, vegetation in and along the drainage is brittlebush scrub. On the west end, it is either unvegetated or non - native and ruderal.
The MSHCP mapped vegetation layer (1994 baseline) depicts the parcel as largely coastal sage scrub with developed/disturbed land on the west end immediately surrounding the existing residence. No riparian or Riversidean alluvial fan sage scrub is mapped on the parcel in the 1994 baseline (RCA 2021).
Based on the grading limits as shown on the TPM plus the fuel modification zone, the total impact area on Lots 2 through 4 plus the road dedication area would be 2. 70 acres. The impact area consists of 1. 99 acres of disturbed/developed/ornamental areas and 0. 72 acre of brittlebush scrub. No temporary impact areas are proposed and all impacts would be permanent. The TPM does not show any impacts to Lot 1 other than the road dedication area.

Brittlebush Scrub
Patches of native scrub vegetation are present in the eastern, southeastern, and south -central portions of the site (Figures 7a and 7b ). Brittlebush (Encelia farinosa) is the dominant shrub associated with this vegetation community on the site and it is best characterized as brittlebush scrub ( Encelia farinosa Shrubland Alliance). The brittlebush scrub on the eastern and southeastern portions of the site is relatively undisturbed. The more centrally located patches of brittlebush scrub on the site have been disturbed by v ehicle tracks and storage of materials, mainly around the periphery of the patches.
Additional perennials associated with this community include California buckwheat ( Eriogonum fasciculatum), California sagebrush ( Artemisia californica ), white sage ( Salvia apiana), and MSHCP Consistency Analysis

cudweed aster ( Corethrogyne filaginifolia var. filaginifolia ). Other native perennials present include blue elderberry (Sambucus nigra ssp. cerulea ) and Anderson box -thorn ( Lycium andersonii). Non -native plants commonly observed include shortpod mustard ( Hirschfeldia incana), wild oat (Avena species), and red brome (Bromus madritensis ssp. rubens). Castor bean (Ricinus communis ), a non -native large shrub or small tree, is conspicuous along the southwestern and south-central site edges in alluvial soils associated with a small onsite drainage.
Brittlebush scrub is ranked as S4 (apparently secure, uncommon but not rare) and is not considered sensitive (CDFW 2020).
Disturbed/Developed/Ornamental
The disturbed/developed/ornamental portion of the property is occupied by the residence and associated structures, driveway, trees, lawn, and garden; the two wells and the unimproved access road for the wells; trees and fencing along Alpine Meadows Lane; and the cleared area in the western and north-central areas of the site.
Disturbed areas that are not vegetated with ornamental plants are sparsely to densely inhabited by various non-native annual plants, including non-native grasses (Bromus species and Schismus barbatus), mustards (Hirschfeldia incana and Sisymbrium irio), Russian thistle ( Salsola tragus), tocalote ( Centaurea melitensis ), filaree ( Erodium species), horehound ( Marrubium vulgare ), cheeseweed (Malva parviflora), and tree tobacco (Nicotiana glauca).
Some native annual plants that are tolerant of disturbed places are also present and include large flower rancher’s fiddleneck (Amsinckia intermedia ), western sunflower ( Helianthus annuus ), jimsonweed (Datura wrightii), and horseweed (Erigeron canadensis).
Non-native ornamental landscaping include s Peruvian pepper tree (Schinus molle ), blue jacaranda (Jacaranda mimosifolia), eucalyptus (Eucalyptus species), pine (Pinus species), elm (Ulmus species), acacia (Acacia longifolia), crepe myrtle (Lagerstroemia species), and Mexican fan palm ( Washingtonia robusta ). Additional unidentified ornamental shrubs and smaller landscape annuals are present.
Non-native weedy plants are present in the landscaped areas and include (but are not limited to) common sow thistle ( Sonchus oleraceus ), prickly lettuce ( Lactuca serriola ), lamb's -quarters (Chenopodium album ), pineapple weed ( Matricaria discoidea ), and tumbling pigweed (Amaranthus albus).

Sawyer et al. (2009) does not provide a classification for disturbed or ornamental areas. CDFW does not assign an S rank to non -native vegetation communities and they are not considered sensitive (CDFW 2020).
4.3) Impacts
Grading will include the northern portions of Lots 2 through 4 . Grading areas plus the road dedication area and fuel modification zone will impact 1. 99 acres of disturbed/developed/ornamental areas and 0.72 acre of disturbed brittlebush scrub.
4.4) Mitigation
The majority of the impact area is disturbed/developed/ornamental areas. Brittlebush scrub is not considered sensitive and no mitigation is proposed.

5.1.1) Methods
Pre-Survey Research Methods and Purpose
A wealth of information is available online and is updated at regular intervals by the agencies and universities. To ensure efficiency and greater accuracy in the field, areas of interest are identified during the research stage prior to conducting the field survey. Useful maps are uploaded to handheld GPS and applications are downloaded in preparation for real -time data inquiries.
Potential for jurisdictional features (riparian/riverine) to occur onsite is assessed via aerial photography, topographic mapping, soil types, trends to hydric conditions, area hydrology, and prior wetlands inventory mapping, etc. Finally, condition of area drainages is forecast based on available rainfall data.
Online data sources include wildlife agencies, California Native Plant Society (CNPS), California Natural Diversity Database (CNDDB), WebSoil, GlobeXplorer, Google Earth, 2016 Arid West Regional Wetland Plant List, Natural Resources Conservation Service, University of California at Davis, Agriculture and Natural Resources, California Soil Resources Lab, U.

Field Survey Methods and Purpose
Field work was conducted by L&L delineator Leslie Irish on September 7, 2021. L&L visited the site and examined the drainage width and length. Aerial images of previous years available in Google Earth were reviewed and compared to verify consistency and to detect any anomalies for further examination in the field.
Project boundaries were investigated to identify areas where water is received onto the property or transmitted offsite to downstream resources. These areas were then walked, measured, and assessed via three (3) criteria to determine presence or absence of evidence of flow, hydrophilic vegetation, or hydric soil conditions. Where evidence of flow was present, combined with or without hydrophytes, soils were examined for anoxic conditions. Soils identified as suitable for development of hydric conditions were given spec ial attention. Soil color characteristics were evaluated using a “Munsell color chart” and all data were reported on appropriate Arid West Wetland Determination Data Forms (WD).
The hydrology criterion is satisfied by the observation of standing or flow ing water. The soil condition is satisfied by the development of saturated soils with anoxic conditions. The vegetation criterion is satisfied if half or more of the dominant plant species within a feature are ranked as "obligate wetland," "facultative w etland," or "facultative" species (OBL, FACW, or FAC, respectively, see Table 4) for federal jurisdiction or by presence of any of these species for state/local jurisdiction. A Wetland Data Point (WDP) was collected for each test pit location and a WD For m was completed. During analysis, L&L used the indicators found in Table 4 as evidence of wetlands vegetation.

Table 4. Summary of wetlands vegetation indicator categories Indicator
Status Symbol Definitions
Obligate OBL
Almost always occur in wetlands. With few exceptions, these plants (herbaceous or woody) are found in standing water or seasonally saturated soils (14 or more consecutive days) near the surface.
Facultative
Wetland FACW
Usually occur in wetlands but may occur in non-wetlands.
These plants predominantly occur with hydric soils, often in geomorphic settings where water saturates the soils or floods the soil surface at least seasonally.
Facultative FAC
Occur in wetlands and non-wetlands. These plants can grow in hydric, mesic, or xeric habitats. The occurrence of these plants in different habitats represents responses to a variety of environmental variables other than just hydrology, such as shade tolerance, soil pH, and elevation, and they have a wide tolerance of soil moisture conditions.
Facultative
Upland FACU
Usually occur in non-wetlands but may occur in wetlands.
These plants predominantly occur on drier or more mesic sites in geomorphic settings where water rarely saturates the soils or floods the soil surface seasonally.
Upland UPL
Almost never occur in wetlands. These plants occupy mesic to xeric non-wetland habitats. They almost never occur in standing water or saturated soils. Typical growth forms include herbaceous, shrubs, woody vines, and trees.
Vernal Pools
During our investigation, the property was searched for vernal pools. To meet the definition of a vernal pool three (3) factors must be addressed: (1 ) suitable soil and soil conditions, (2) proper hydrology, and (3) one or more indicator species. Two (2) pools/ponds were assessed during our study. Test pits were excavated at both locations and a wet season fairy shrimp survey was initiated.
Nomenclature Used
Terminology has changed over the years. Toward greater clarity and understanding, L&L used terms in this report that follow RCA guidelines, both published and expressed. We also describe linear features or channels as riverine and woody facultative habitat as riparian.

5.1.2) Existing Conditions and Results
An ephemeral drainage (not a blueline) runs from east to west through the southeastern portion of the site. The jurisdictional delineation found 0.46 acre of MSHCP riverine habitat and no MSHCP riparian habitat in this drainage (Table 5 and Figure 8).
There has been disturbance to the drainage, particularly on the west end. On the east end, vegetation in and along the drainage is brittlebush scrub. On the west end, it is either unvegetated or non-native and ruderal.

5.1.3) Impacts
Impacts to MSHCP riparian/riverine habitat require the preparation of a Determination of Biologically Equivalent or Superior Preservation (DBESP). Based on TPM 38174 (Appendix B), the Project will avoid impacts to the drainage and riverine habitat and a DBESP is therefore not required.
5.1.4) Mitigation
No MSHCP riparian habitat is present and Project will avoid the riverine habitat. Therefore, no mitigation is proposed.

5.2) Vernal Pools
5.2.1) Methods
The site was surveyed in June and July of 2021 (see Table 2) including an assessment of the potential for vernal pools or ponding areas and associated species. The jurisdictional delineation also evaluated the site for the presence of vernal pools or evidence of ponding areas.
5.2.2) Existing Conditions and Results
Soil types mapped on the site are not consistent with an alkali playa or vernal pool complex (Bauder et al 2011). Pools or depressions characteristic of vernal habitat were not observed on the site and no wetland or vernal pool plant species were present. No evidence of ponding areas (i.e., cracked soils, tire ruts, etc.) were observed on the site during surveys.
5.2.3) Impacts
No vernal pools are present on the site and none would be impacted.
5.2.4) Mitigation
The Project would not impact any vernal pools and no mitigation is proposed.

5.4) Riparian Birds
5.4.1) Methods
A biological resources assessment survey and vegetation mapping was conducted by L&L biologist Guy Bruyea (see Section 4.1). No protocol surveys for riparian birds were conducted.
5.4.2) Existing Conditions and Results
Least Bell’s vireo (Vireo bellii pusillus) is state and federally listed as endangered. It is a covered species under the MSHCP and considered adequately conserved, but surveys are required in suitable habitat as described in MSHCP Section 6.1.2 and mitigation is required if the species is present. This species is migratory and breeds in California , arriving in March and departing by September or October. Males establish and defend territories in riparian woodlands and riparian scrub. Territory size ranges from 0.5 to 7.5 acres (USFWS 1998). Dense shrub cover is required for nesting.
There are 22 CNDDB documented occurrences of nesting least Bell’s vireo within five (5) miles of the site. The closest is within Prenda Arroyo, about 0.5 miles east of the site in an area of dense riparian vegetation that extends along Prenda Creek for about a mile. There is no riparian habitat on the site and no suitable habitat for least Bell’s vireo. Riparian vegetation near the site includes a few isolated willows adjacent to the site on the eastern boundary and riparian vegetation in Prenda Creek, to the south of the site. The isolated willows to the east do not provide the dense cover and/or the extent of habitat required by least Bell’s vireo. The riparian vegetation in Prenda Creek south of the site includes mulefat (Baccharis salicifolia), willows (Salix species), cottonwood ( Populus fremontii ), tamarisk ( Tamarix species), castor bean ( Ricinus communis), arundo (Arundo donax), and other species. This area provides potentially suitable habitat for least Bell’s vireo.
Southwestern willow flycatcher ( Empidonax traillii extimus ) is state and federally listed as endangered. It is a covered species under the MSHCP and considered adequately conserved, but surveys are required in suitable habitat as described in MSHCP Section 6.1.2 and mitigation is required if the species is present . This species inhabits dense riparian forests with ample numbers of willows and other associated trees and shrubs.
MSHCP Consistency Analysis
Alpine Meadows Estates, City of Riverside, Riverside County, California March 2023
QUIN-05-R752.CD1 (final).rev4 clean 33 L&L
There are no CNDDB documented occurrences of nesting southwestern willow flycatcher within five (5) miles of the site. There is no riparian habitat on the site and no habitat for southwestern willow flycatcher. However, there is riparian vegetation within Prenda Creek. This area consists mainly of mulefat and shrubby willows with some cottonwood tr ees. This offsite area provides potentially marginal habitat for southwestern willow flycatcher.
Western yellow-billed cuckoo (Coccyzus americanus occidentalis) is federally listed as threatened and state listed as endangered. It is a covered species und er the MSHCP and considered adequately conserved, but surveys are required in suitable habitat as described in MSHCP Section 6.1.2 and mitigation is required if the species is present. This species inhabits extensive riparian thickets or forests with dense, low-level or understory foliage and abutting on slow-moving watercourses, backwaters, or seeps.
There is one CNDDB documented occurrences of nesting western yellow-billed cuckoo within five (5) miles of the site. This occurrence is from 1894 in the Riverside area, exact location unknown, and mapped 3.7 miles north of the site. The CNDDB lists this occurrence as extirpated by development. There is no riparian habitat on the site and no habitat for western yellow -billed cuckoo. The riparian vegetatio n within Prenda Creek likely does not provide the dense cover and/or the extent of habitat required by the western yellow-billed cuckoo.
There is no suitable habitat for least Bell’s vireo, southwestern willow flycatcher, or western yellow-billed cuckoo on or immediately adjacent to the site. Riparian vegetation is present in Prenda Creek to the south of the site. A protocol survey for riparian birds was not conducted, but Prenda Creek provides potentially suitable habitat for least Bell’s vireo and potentially marginal habitat for southwestern willow flycatcher. This area likely does not provide suitable habitat for western yellow-billed cuckoo.
5.4.3) Impacts
Based on TPM 38174 and review of aerial images (Google Earth 2021), the grading areas on the Project site are at least 300 feet away from the suitable riparian habitat in Prenda Creek (Figure 9). However, impacts to these species are possible (i.e., noise and disturbance) if the Project grading plans are revised and will encroach within a 300 -foot buffer of the riparian habitat in Prenda Creek to the south of the Project site. Project-related disturbance could cause avoidance of the habitat and/or territory/nest abandonment.

Native riparian habitat is not present within the 300-foot buffer. The buffer includes the edge of a large clump of non-native arundo, also called giant reed (Arundo donax). Arundo is an invasive exotic species that degrades riparian habitat. It is very rarely uti lized as nesting habitat by least Bell’s vireo. An extensive study in the Prado Basin found only 0.8 percent of vireo nests were located in arundo (Pike et al. 2006).

5.4.4) Mitigation
If the Project is revised such that grading impacts will encroach within 300 feet of the riparian habitat in Prenda Creek, proposed mitigation requires either avoidance of the nesting season or a habitat assessment and a protocol survey if suitable habitat is present. If a protocol survey finds any of these species present within 300 feet of the Project disturbance area, additional avoidance and minimization measures are required.
Text of the proposed mitigation measure:
MM BIO-4. Riparian Birds
If Project grading plans are revised such that grading is extended to the south and within a 300 -foot buffer from riparian habitat in Prenda Creek to the south, then either construction shall avoid the nesting season (February 1 to August 31) , or a habitat assessment for riparian birds (least Bell’s vireo, southwestern willow flycatcher, and western yellow-billed cuckoo) in that area shall be completed by a qualified biologist . If suitable habitat for least Bell’s vireo, southwestern willow flycatcher, or western yellow - billed cuckoo is present, then a protocol survey shall be conducted by a qualified and permitted biologist to determine presence or absence of any of these species within 300 feet of Project disturbance areas.
If any of these species are present within 300 feet of the Project disturbance area , additional avoidance and minimization mea sures shall be implemented as identified by the qualified biologist in consultation with the Western Riverside County Regional Conservation Authority, California Department of Fish and Wildlife , and U.S. Fish and Wildlife Service.
With implementation of recommended mitigation, the Project would be consistent with the MSHCP.
5.5) Other Section 6.1.2 Species
Other Section 6.1.2 species are either absent, not expected to occur, or have a low potential for occurrence (Table 6). The Project will avoid impacts to the riverine habitat.

“Documented occurrences” refers to species occurrences in the California Natural Diversity Database (CNDDB) unless otherwise noted. For plant species that are not tracked in the CNDDB, records from the Consortium of California Herbaria (CCH) may be used (only CCH records that include map coordinates are utilized). EBird (eBird.org) is an online database of bird distribution and abundance sponsored by the Cornell Laboratory of Ornithology and compiled from observations submitted by citizen scientists. eBird records of bird observations are noted but should be interpreted with caution. eBird records “in vicinity” means records within about a 5-mile radius of the site.
Definitions of occurrence probability:
These definitions provide general guidance. Classifications for individual species may be modified based on biologists’ experience and expert opinion.
Occurs: Species was detected during surveys or previously documented on the Project site or adjacent areas .
High: Species documented in the vicinity (i.e., within 5 miles) o f the Project site and suitable habitat is present, but species not detected during surveys.
Moderate: Species documented in the vicinity of the Project site or suitable habitat present and site is within geographic and elevational range of the species.
Low: Species not documented in the vicinity of the Project site or suitable habitat is marginal .
Not Expected: Species not documented in the vicinity of the Project site and suitable habitat marginal or absent, or site is not within geographic and elevational range of the species.
Absent: No potential for the species to occur due to lack of habitat, geographic or elevation range, species life history, survey results, etc.
Unknown: No focused surveys have been performed in the region, and the species' distribution and habitat are poorly known.

Based on review of the MSHCP Information Map (RCA 2021) for the parcel, the Project is within the mapped survey area for burrowing owl (Athene cunicularia) and a habitat assessment is required. If suitable habitat is present, focused surveys are required.
7.3.1) Methods
A habitat assessment for burrowing owl was conducted on June 22, 2021 and found potentially suitable habitat for burrowing owl, including open areas onsite and areas where California ground squirrel (Spermophilus beechyi) or other small mammal activity was observed (i.e., potentially suitable burrows).
A focused burrow survey and focused burrowing owl survey was conducted on June 22, July 7, July 19, and July 28, 2021 in areas identified during the habitat assessment as potential burrowing owl habitat (Table 7). An additional 150-meter (500-foot) buffer area surrounding the site was visually inspected, where possible, in areas identified as potential burrowing owl habitat (Figure 10). Any developed areas were visually surveyed with binoculars due to private property trespassing concerns.

The site and buffer area were examined for suitable burrow sites and for signs of occupation by burrowing owl, including pellets, feathers, whitewash, prey remains, and eggshell fragments, as well as individual owls. A search for potentially suitable burrows within dirt, wood, or rock debris piles, artificially created berms, and other locations was conducted during surveys.
Transects were walked throughout the property where suitable habitat is present. Coupled with binocular surveys of any restricted offsite areas, this allowed for complete visual ground coverage of the survey area. Distance between transects was approximately 15 to 20 meters.
Per MSHCP protocol for burrowing owl surveys (RCA 2006), surveys should be conducted during weather that is conducive to observing owls outs ide their burrows and detecting burrowing owl sign. Surveys will not be accepted if they are conducted during rain, high winds (> 20 mph), dense fog, or temperatures over 90°F. Surveys should be conducted in the morning one hour before sunrise to two hou rs after sunrise or in the early evening two (2) hours before sunset to one (1) hour after sunset. Surveys were conducted during appropriate hours and weather conditions (Table 7).

7.3.2) Existing Conditions and Results
Burrowing owl (Athene cunicularia) is protected under the federal Migratory Bird Treaty Act and California Fish and Game Code and is a CDFW Species of Special Concern. It is a small, ground- dwelling owl found in open dry grassland, desert, or shrubland areas and in uncultivated agricultural areas, rangelands, and other open areas with low-growing vegetation.
Burrows are an essential element of burrowing owl habitat. Although burrowing owl is capable of excavating its own burrows in soft soils, it typically modifies and inhabits abandon ed burrows of small burrowing mammals, such as ground squirrels and pocket gophers. Burrowing owl has also been known to use man-made structures such as cement culverts, debris piles, and other artificial burrows.
Occupancy of burrowing owl habitat can be verified at a site by observation of at least one (1) owl or owl sign (molted feathers, cast pellets, prey remains, eggshell fragments, or excrement) at or near a burrow entrance. A site is considered occupied if at least one (1) owl has been identified onsite in the past three (3) years, because (if undisturbed) burrowing owls exhibit high site fidelity (CDFG 2012, CBOC 1993).
There are six (6) CNDDB documented occurrences of burrowing owl within five (5) miles of the Project site (CDFW 2021c). The closest is Element Occurrence (EO) #1074, located about 0.5 mile west of the site and downstream of Prenda Dam. This occurrence is from 2004 and consisted of a breeding pair. The CNDDB records it as extirpated.
EO #441 is from 1989 and consisted of one adult. It is about 2.3 miles southwest of the site. The CNDDB records this occurrence as presumed extant but (based on Google Earth aerial images) the area is now developed.
EO #1283 and 1284 were both observed at the March Air Force Base St ephens’ Kangaroo Rat Preserve in 2009. These records consist of a breeding pair with a chick and a breeding pair, respectively. These occurrences are 2.7 and 2.6 miles east of the site, respectively, and are assumed to be extant.
EO #929 is from 2006 and is about 2.9 miles southeast of the site. The record consists of one adult. Based on Google Earth aerial images, this location remains undeveloped agricultural fields and this occurrence is assumed to be extant.

EO #1771 was observed at the Riverside Municipal Airport in 2007 and is 4.8 miles northwest of the site. This occurrence consists of two adults assumed to be a breeding pair and is assumed to be extant.
There are four (4) eBird records of burrowing owl observations within five (5) miles of the Project site (eBird 2021). One record consists of multiple observations of one to five burrowing owls from January to November 2008. The July observation was of two juveniles and one adult. This record is from the Riverside Municipal Airport and appears to be the same location as EO #1771.
The second record is from December 2016 at the Ben Clark Public Training Center, about 4.0 miles southeast of the site. This record consists of one burrowing owl. The third and fourth records are in close proximity to each other at/near the Sycamore Canyon Wilderness Park, about
3.1 miles northeast of the site. These records are from May 2007 and September 2013 and consist of one and two burrowing owls, respectively.
No burrowing owls, owl sign (pellets, scat, fe athers, tracks, etc.), or occupied burrows were observed onsite during the 2006 survey or 2021 protocol breeding season survey. Potentially suitable burrowing owl habitat is present on the site, including small mammal burrows and cavities under rock/concrete debris. Potentially suitable habitat is also present within the 150-meter buffer area, but no owls, owl sign, or occupied burrows were observed in the buffer.
Potentially suitable burrowing owl habitat is present on the site, including small mammal burrows (see Figure 11 and Exhibit 1). No burrowing owls, owl sign (pellets, scat, feathers, tracks, etc.), or occupied burrows were observed onsite during the 2006 or 2021 surveys. Potentially suitable habitat is also present within the buffer area (Figure 6), but no owls, owl sign, or occupied burrows were observed in the buffer.

7.3.3) Impacts
No burrowing owls were detected utilizing the site and under current conditions, impacts to burrowing owl would be limited to loss of potential but unoccupied habitat. If burrowing owls colonize the site prior to the start of construction, potential Project impacts include loss of occupied habitat and active burrows and potential injury/mortality of burrowing owls, including eggs and chicks.
7.3.4) Mitigation
Since potentially suitable habitat is present, the MSHCP requires a preconstruction clearance survey for burrowing owl within 30 days prior to initial ground and/or vegetation disturbance. If ground-disturbing activities occur, but the site is left undisturbed for more than 30 days, a pre-construction survey will again b e necessary to ensure burrowing has not colonized the site since it was last disturbed. If burrowing owl is present during a preconstruction survey, the Project proponent will be required to prepare a Burrowing Owl Protection and Relocation Plan (Plan).
Text of the proposed mitigation measure:
MM BIO-1. Burrowing Owl
A preconstruction clearance survey for burrowing owl shall be conducted by a qualified biologist and the results submitted to the City of Riverside within no more than 30 calendar days prior to any site disturbance, including vegetation clearing/grubbing, ground disturbance, fence installation, demolition, etc. The survey will be conducted as close to the actual initiation of site disturbance as possible. The survey is valid for 30 calendar days. If work does not commence within the 30 days, the survey s hall be repeated. If work starts and is suspended for 30 or more calendar days, the survey shall be repeated.
If burrowing owls are found on the site during the preconstruction survey, the Project biologist shall consult with the City of Riverside , the Western Riverside County Regional Conservation Authority (RCA), and the California Department of Fish and Wildlife as needed to develop and implement a mitigation plan. The mitigation plan shall be based on the following goals and requirements in the MSHCP:
1. If the site contains or is part of an area supporting less than 35 acres of suitable habitat or the survey reveals that the site and the surrounding area supports fewer MSHCP Consistency Analysis
Alpine Meadows Estates, City of Riverside, Riverside County, California March 2023
QUIN-05-R752.CD1 (final).rev4 clean 50 L&L
than three (3) pairs of burrowing owls, the onsite burrowing owls will be passively or actively relocated following accepted protocols.
a. Occupied nests shall be avoided during the nesting season (February 1 to August 31) and a buffer of 300 to 500 feet shall be employed, depending on the level of disturbance surrounding the burrow.
b. Burrow exclusion shall be utilized outside of the nesting season by installing a one-way door in burrow openings. The burrow shall be closed following verification that burrows are empty (through site monitoring and scoping).
c. Prior to implementation of exclusion and/or relocation, a relocation plan shall be prepared for review and approval by the California Department of Fish and Wildlife. This plan shall include, but not be limited to, the following:
• Project Overview
• Species Biology
• Summary of Burrowing Owl Surveys and Results
• Impact Avoidance and Minimization including buffers,
monitoring during construction, worker environmental
awareness program, and other measures
• Relocation Methods including location of adjacent suitable habitat and replacement bu rrows, conservation and
management of relocation area, enhancement of replacement burrows and/or construction of artificial burrows, ratio of replacement burrows to removed burrows, timing of relocation, burrow exclusion, and burrow inspection and excavati on of removed burrows
• Monitoring and Reporting including monitoring during and after construction, surveys, cleaning and maintenance and/or
replacement of artificial burrows, duration of monitoring, and reporting requirements

2. If the site (including adja cent areas) supports three (3) or more pairs of burrowing owls, supports greater than 35 acres of suitable habitat, and is noncontiguous with MSHCP Conservation Area lands, at least 90 percent of the area with long-term conservation value and burrowing owl pairs shall be conserved onsite.
With implementation of recommended mitigation, the Project would be consistent with the MSHCP.
7.4) Mammals
Based on review of the MSHCP Information Map (RCA 2021) for the parcel, the Project site is not within a mapped survey area for mammal species and surveys for mammal species are not required.

8.3) Other Species
Three special status wildlife species were observed during the 2021 surveys, Cooper’s hawk (Accipiter cooperii; CDFW Watch List species), Nuttall’s woodpecker ( Picoides nuttallii; USFWS Bird of Conservation Concern), and San Diego desert woodrat (middens) (Neotoma lepida intermedia; CDFW Species of Special Concern). Details of these observations are provided in Table 9 and observation locations are shown on Figure 12. No special status wildlife species were noted during the 2006 survey.
Cooper’s hawk and San Diego desert woodrat are covered under the MSHCP and considered adequately conserved. Nuttall’s woodpecker is not covered under the MSHCP. Recommended mitigation includes avoidance of Project impacts during the nesting season (February 1 to August 31) or implementation of preconstruction nesting bird clearance surveys and avoidance buffers for active nests.
Text of the proposed mitigation measure:
MM BIO-2. Nesting Birds
Site disturbance (vegetation and /or ground disturbance, tree trimming/encroachment/removal, fence installation, demolition, etc.) shall be scheduled outside of the nesting season (February 1 to August 31 ). If site disturbance cannot be scheduled outside the nesting season, a preconstruction survey for nesting birds shall be conducted by a qualified biologist within three (3) days prior to any site disturbance during the nesting season.
If active nest(s) are present, an avoidance buffer of 500 feet for raptors and special status birds and 300 feet for all other birds (or as recommended by the biologist) shall be established and maintained until a qualified biologist has determined that the juvenile birds have fledged and are no longer dependent on the nest or the nest has otherwise become MSHCP Consistency Analysis
Alpine Meadows Estates, City of Riverside, Riverside County, California March 2023
QUIN-05-R752.CD1 (final).rev4 clean 57 L&L
inactive. An active nest is defined as a nest with eggs, chicks, or dependent juveniles, or a nest actively being constructed or utilized for reproduction.
The size of the avoidance buffer shall be determined by the biologist based on the nature of Project activities, the birds’ tolerance to disturbance (if known), conservation status of the affected species, and any applicable agency recommendations or requirements. The boundary of the buffer shall be clearly flagged or marked, and construction crews informed of the restrictions.
Four (4) middens (stick nests) of San Diego desert woodrat were observed in the northeast corner of the site in piles of rocks and concrete debris during the 2021 surveys (middens were not noted during the 2006 survey). The nest materials appeared weathered and there was no sign of recent activity at any of the middens. In coastal scrub habitat, the home range of this species is 0.1 to
0.5 acre (CDFW 2008). Based on the locations of the middens, the home ranges of the occupants (if present) would likely be confined to the open space easement and adjacent offsite areas to the east. Under the MSHCP, a survey is not required for San Diego desert woodrat.

The long-term anthropogenic disturbances on the site limit the potential for listed and special status wildlife species known from the region to occur on the site. Most are absent, not expected to occur, or have a low potential for occurrence. Species that have a low to moderate, moderate, or high potential to occur are:

• Western mastiff bat (foraging) (Eumops perotis californicus ; CDFW Species of Special Concern).
None of these species were observed during surveys in 2006 or 2021. These species are covered under the MSHCP and considered adequately conserved, with the exception of Crotch bumble
2 Based on CDFW information, crotch bumble bee was previously a candidate for state listing (CDFW 2021a, 2022), but the Sacramento Superior Cou rt ruled that insects are not eligible for listing under the California Endangered Species Act : Almond Alliance of California v. California Department of Fish and Wildlife, Sacramento Superior Court No. 34 -2019-80003216 (Nov. 13, 2020). The California Fis h and Game Commission filed an intent to appeal this decision in February 2021. On May 31, 2022, California's Third District Court of Appeal ruled that the California Endangered Species Act can protect invertebrates, including crotch bumble bee (CFS 2022). A State Supreme Court ruling reinstated its candidacy on September 30, 2022 (Supreme Court Case S275412).

bee, Southern California legless lizard, Allen’s hummingbird, pallid bat, and western mastiff bat.
These five species are not covered under the MSHCP.
Crotch bumble bee was originally advanced to candidacy for state listing in June 2019. This status was challenged in court and a trial court decision temporarily r emoved its candidacy in February 2021. A State Supreme Court ruling reversed this judgement and reinstated its candidacy on September 30, 2022 (Supreme Court Case S275412). The latest information from CDFW indicates that crotch bumble bee is a candidate for state listing as endangered. Under the California Endangered Species Act, candidate species receive the same protections as a listed species. This species was not observed on the site but surveys for invertebrates were not conducted. Crotch bumble bee has a low to moderate potential for occurrence on the site, mainly in the avoided area.
Text of proposed mitigation measure:
MM BIO-3. Crotch Bumble Bee
Prior to the start of Project activities on the site (i.e., ground or vegetation disturbing activities), a qualified biologist shall conduct a focused survey for crotch bumble bee using the CDFW survey protocol for this species. If CDFW has not established a survey protocol for crotch bumble bee, a focused survey shall be conducted during the appropriate season and utilizing an appropriate survey method based on the species’ biology. Survey results shall be provided to the City of Riverside and CDFW.
If the survey finds that crotch bumble bee is present on the site, the biologist shall consult with CDFW. If the Project will impact crotch bumble bee, an incidental take permit from the CDFW shall be obtained and/or other measures shall be implemented as required by CDFW.
Impacts to the other four (4) species not covered under the MSHCP are not expected to be significant. The Project site is not within the Criteria Area or PQP Lands so the restriction on clearing coastal California gnatcatcher occupied habitat between Marc h 1 and August 15 does not apply.

9.0) BEST MANAGEMENT PRACTICES (MSHCP VOLUME 1, APPENDIX C) Volume 1, Appendix C of the MSHCP includes best management practices (BMPs) to be implemented if project activities could directly or indirectly impact MSHCP resources. Based on the potential for direct or indirect impacts to MSHCP resources, the Project will implement BMPs #2, 3, 5, 6, 8, 9, 11, 13, 14, and 15 and these will be added as notes in the grading plans. BMPs #7 and 12 are not applicable to the Project. BMPs #1, 4, 10 are associated with biological monitoring and are not proposed for the Project.
The MSHCP BMPs are:
1. A condition shall be placed on grading permits requiring a qualified biologist to conduct a training session for project personnel prior to grading. The training shall include a description of the species of concern and its ha bitats, the general provisions of the Endangered Species Act (Act) and the MSHCP, the need to adhere to the provisions of the Act and the MSHCP, the penalties associated with violating the provisions of the Act, the general measures that are being implemented to conserve the species of concern as they relate to the project, and the access routes to and project site boundaries within which the project activities must be accomplished.
2. Water pollution and erosion control plans shall be developed and implemented in accordance with RWQCB [Regional Water Quality Control Board] requirements.
3. The footprint of disturbance shall be minimized to the maximum extent feasible. Access to sites shall be via pre-existing access routes to the greatest extent possible.
4. The upstream and downstream limits of projects disturbance plus lateral limits of disturbance on either side of the stream shall be clearly defined and marked in the field and reviewed by the biologist prior to initiation of work.
5. Projects should be designed to avoid the placement of equipment and personnel within the stream channel or on sand and gravel bars, banks, and adjacent upland habitats used by target species of concern.
6. Projects that cannot be conducted without placing equipment or personnel in sensitive habitats should be timed to avoid the breeding season of riparian [species] identified in MSHCP Global Species Objective No. 7.

7. When stream flows must be diverted, the diversions shall be conducted using sandbags or other meth ods requiring minimal instream impacts. Silt fencing of other sediment trapping materials shall be installed at the downstream end of construction activity to minimize the transport of sediments offsite. Settling ponds where sediment is collected shall be cleaned out in a manner that prevents the sediment from reentering the stream. Care shall be exercised when removing silt fences, as feasible, to prevent debris or sediment from returning to the stream.
8. Equipment storage, fueling, and staging areas shall be located on upland sites with minimal risks of direct drainage into riparian areas or other sensitive habitats. These designated areas shall be located in such a manner as to prevent any runoff from entering sensitive habitat.
Necessary precautions shall be taken to prevent the release of cement or other toxic substances into surface waters. Project related spills of hazardous materials shall be reported to appropriate entities including but not limited to applicable jurisdictional city, FW S [U.S. Fish and Wildlife Service], and CDFG [California Department of Fish and Wildlife] , [and] RWQCB and shall be cleaned up immediately and contaminated soils removed to approved disposal areas.
9. Erodible fill material shall not be deposited into wate r courses. Brush, loose soils, or other similar debris material shall not be stockpiled within the stream channel or on its banks.
10. The qualified project biologist shall monitor construction activities for the duration of the project to ensure that practicable measures are being employed to avoid incidental disturbance of habitat and species of concern outside the project footprint.
11. The removal of native vegetation shall be avoided and minimized to the maximum extent practicable. Temporary impacts shall be returned to pre-existing contours and revegetated with appropriate native species.
12. Exotic species that prey upon or displace target species of concern should be permanently removed from the site to the extent feasible.
13. To avoid attracting predators of the species of concern, the project site shall be kept as clean of debris as possible. All food related trash items shall be enclosed in sealed containers and regularly removed from the site(s).
14. Construction employees shall strictly limi t their activities, vehicles, equipment, and construction materials to the proposed project footprint and designated staging areas and routes of travel. The construction area(s) shall be the minimal area necessary to complete the project and shall be spec ified in the construction plans. Construction limits will be fenced with orange MSHCP Consistency Analysis

Report Summary:
Within the project footprint one ( 1) jurisdictional drainage was identified. The drainage does not include any USGS mapped blue-line streambed. The nearest mapped ephemeral blue-line stream is approximately 450 feet south of the site. Jurisdictional areas on the project site include 20, 222 sq. ft. (0.46 acre) of state streambed and 20,222 sq. ft. ( 0.46 acre) of MSHCP riverine habitat. Of this, 3,834 sq. ft. ( 0.088 acre) comprise federal jurisdictional drainages or “waters of the U. S.” No state or federal wetlands or MSHCP riparian habitat were identified onsite. One willow is located upstream, offsite. No vernal pool, fairy shrimp, or potential fairy shrimp habitat was found. Development plans submitted to L&L indicate no direct impacts to state streambed, federal “waters of the U. S.,” or MSHCP vegetation. L&L recommends appropriate BMPs to ensure grading on slopes above drainage areas does not result in debris entering the drainage.

MANAGEMENT SUMMARY
At the request of Robert Quintero of Landbuild, L&L Environmental, Inc. (L&L) conducted a preliminary jurisdictional delineation on ±5.74 acres identified as APN 243-230-027 (TPM 38174) in the City of Riverside, Riverside County, California. The purpose of this delineation is to quantify that portion of the property subject to the jurisdiction of the California Department of Fish and Wildlife (CDFW) and the Regional Water Quality Control Board (RWQCB) and subject to Section
6.1.2 of the Western Riverside County Multiple Species Habitat Conservation Plan (MSHCP). A jurisdictional determination is performed to map wetland and non-wetland features on the property that may be subject to regulation by state or federal agencies and may require permits prior to disturbance/construction. All jurisdictional delineations are considered preliminary until verified and accepted by the agencies.
Due to changes in regulatory guidelines, multiple reports are now required for permit application submittal packages. This report has been written for the lead agency to support the CEQA process and includes combined agency information. At the regulatory permit submittal stage, this report will be reformatted into the following: 1) a federal level document intended for use with the U. S. Army Corps of Engineers (USACE); 2) a Regional Water Quality Control Board (RWQCB) appropriate document suitable under Section 401 of the Clean Water Act , including a Least Environmentally Damaging Practicable Alternative (LEDPA) Analysis or Porter Cologne Analysis to support a Waste Discharge Permit ; 3) a State of California level document intended for use with the CDFW under the 1600 Code; and 4) a Western Riverside County Multiple Species Habitat Conservation Plan (MSHCP) Section 6.1.2 document, that defines riparian/riverine and vernal pool resources. This report is not intended to be appropriate for submittal to the regulatory agencies for state or federal level jurisdictional permits.
L&L’s regulatory analysts and wetland delineator Leslie Irish and Joshua Ball evaluated the site during a series of actions that included pre -survey research and data review followed by a field survey and mapping effort conducted on the property September 7 th 2021. The research consisted of a review of topographic maps, soils information, and aerial photography and a field examination of vegetation, soils, and hydrology using definitions contained in the Arid West Guidelines. Post processing of data included a review of files collected with along with topographic maps and Google Earth.
The project is located on a 5.74-acre fenced parcel at 841 Alpine Meadows Lane. The majority of the property is disturbed by regular tilling for weed abatement purposes. A single residence is Jurisdictional Delineation
TPM 38174, City of Riverside, Riverside County, CA July 2022 QUIN-05-752.JD2 (CEQA) 4 L&L
present within the westernmost portion of the parcel and ornamental trees are located along Alpine Meadows Lane. Riversidean Sage Scrub is located on steeper slopes not included in regular weed abatement tilling.
L&L identified 20,222 sf (0.46 acre) of CDFW combined streambeds and MSHCP riparian habitat present on the Project Site. Of this, 3,834 sq. ft. (0.088 acre) may comprise federal jurisdictional drainages or “waters of the U. S.” No state or federal wetlands or MSHCP riparian habitat were identified onsite. No vernal pool, fairy shrimp, or potential fairy shrimp habitat was found.
Development plans submitted to L&L indicate no direct impacts to state streambed, federal “waters of the U. S.,” or MSHCP habitat. L&L recommends appropriate BMPs to ensure grading on slopes above drainage areas does not result in debris entering the drainage.

1.0) INTRODUCTION
The following report was prepared by L&L Environmental, Inc. (L&L) for Landbuild . It describes the results of a jurisdictional delineation conducted on a proposed development site in the City of Riverside in Riverside County, California. The study area consists of Assessor Parcel Number (APN) 243-230-027 (TPM 38174), totaling ±5.74 acres.
Section 404 of the federal Clean Water Act requires permitting of activities that will result in discharge of dredge or fill material into "Waters of the U. S." or adjacent wetlands. The Regional Board is in the process of expanding state laws beyond federal levels. Federal policy directs "no net loss" of wetland habitats. Section 1602 of the California Fish and Game code requires a "Streambed Alteration Agreement" for projects that will alter a stream channel.
This report documents the presence of state streambeds subject to Section 1600 of the California Fish and Game Code present on the Project Site. It also documents presence of drainages subject to control of the Regional Water Quality Control Board and riverine habitat subject to the Western Riverside County Multiple Species Habitat Conservation Plan (MSHCP), Section 6.1.2.
The proponent is advised the drainage may be subject to Section 404 of the Clean Water Act and the Army Corps of Engineers. Consultation with the USACE would determine which of the various jurisdictional rules will be implemented during the life of the project, however because no impact to the drainage is planned this will not be necessary.
All jurisdictional delineations conducted by consultants are considered preliminary until verified and accepted or acted upon by the agencies.

2.0) PROPERTY LOCATION
The study area includes the parcel and offsite improvements located at 841 Alpine Meadows Lane in the City of Riverside in Riverside County, California (Figure 1). Specifically, the site is located just southwest of the intersection of Alpine Meadows Lane and Kingdom Drive. The site is located within Section 13 of Township 3 South, Range 5 West, as shown on a portion of the USGS Riverside East 7.5' topographic quadrangle (Figure 2). The parcel can be accessed by taking the 91 Freeway to Madison Street (Exit 60), turn south and follow the street to Victoria Avenue. Turn northeast on Victoria Avenue and proceed to Washington Street. Follow Washington Street to Bradley Street and turn east. Follow Bradley Street to Harbart Drive and turn north. At the first opportunity turn west on Alpine Meadows Lane and the parcel is the second house/parcel on the right (south side of the street). The site is generally bounded as follows: to the west by a residential structure, with disturbed open space, Prenda Dam, and tract home developments, and Washington Street beyond; to the east by Kingdom Drive, a mixture of relatively undisturbed and disturbed open space, residential areas, with I-215 beyond; to the north by Alpine Meadows Lane, homes associated with Solitude Court , with a mixture of disturbed open space and relatively undisturbed lands and Muirfield Road beyond; and to the south by disturbed open space and a mapped blue-line stream, with residential areas (some still under construction) along Horizon View Drive and Kingdom Drive, with a mixture of disturbed open space and relatively undisturbed areas beyond (Figure 3).
2.1) Property Site Description
The subject property contains evidence of previous disturbance including past clearing, off -road vehicle (ORV) activity and pedestrian use, and the introduction of ornamental trees and other invasive non-native vegetation in association with an onsite residence. A n associated unpaved road is present on the eastern portion of the site. No mapped blueline stream (riparian/riverine area) is present on the site. Two (2) mapped blue-line streams are present near the site to the northwest and south.
2.2) Proposed Project Description
The project is described as Tentative Parcel Map 38174, a division of a single parcel into four (4) lots. The westernmost lot already has a house built on it and the parcel map shows houses to be constructed on Lots 2, 3, and 4 (see Figure 4). The southern area of the parcels to be created are shown avoided within jurisdictional drainage areas.

3.0) METHODS
3.1) Pre-Survey Research Methods and Purpose
In this report, the “Project” or “Project Site” refers to the ±5.74-acre parcel. A report prepared by L&L in 2006 (L&L 2006) was examined for comparison with current conditions onsite. A wealth of information is available online and is updated at regular intervals by agencies and universities.
To ensure efficiency and greater accuracy in the field, areas of interest were identified during the research stage prior to conducting the field survey. Useful maps were uploaded to handheld GPS and applications we re downloaded in preparation for real -time data inquiries. Potential for jurisdictional features and riparian/riverine habitat to occur onsite wa s assessed via aerial photography, topographic mapping, soil types, trends to hydric conditions, area hydrology, and prior wetlands inventory mapping, etc. Finally, condition of area drainages was forecast based on available rainfall data.
Online data sources include wildlife agencies, California Native Plant Society (CNPS), California Natural Diversity Database (CNDDB), WebSoil, GlobeXplorer, Google Earth, 2016 Arid West Regional Wetland Plant List, Natural Resources Conservation Service, University of California at Davis, Agriculture and Natural Resources, California Soil Resources Lab, U.

3.2) Field Survey Methods and Purpose
Field work was conducted on September 7
th, 2021, by Leslie Irish and Joshua Ball, during which three (3) person hours were expended. P roject boundaries were investigated to identify areas where water is received onto the property or transmitted offsite to downstream resources. These Jurisdictional Delineation
TPM 38174, City of Riverside, Riverside County, CA July 2022 QUIN-05-752.JD2 (CEQA) 11 L&L
areas were then walked, measured, and assessed via three (3) criteria to determine presence or absence of evidence of flow, hydrophilic vegetation, or hydric soil conditions. Where evidence of flow is present, combined with or without hydrophytes, soils were examined for anoxic conditions.
Soils identified as suitable for development of hydric conditions were given special attention. Soil color characteristics were evaluated using a “Munsell color chart” and all data are reported on appropriate Arid West Wetland Determination Data Forms (WD). The hydrology criterion is satisfied by the observation of standing or flowing water. The soil condition is satisfied by the development of saturated soils with anoxic conditions. The vegetation criterion is satisfied if half or more of the dominant plant species within a feature are ranked as "obligate wetland," "facultative wetland," or "facultative" species (OBL, FACW, or FAC, respectively, see Table 1) for federal jurisdiction, presence of any of these species for state/local jurisdiction, or the presence of woody facultative species for MSHCP jurisdiction.
During our analysis, L&L personnel used the following indicators of wetlands vegetation:
Table 1. Summary of wetlands vegetation indicator categories.
Indicator
Status Symbol Definitions
Obligate OBL
Almost always occur in wetlands. With few exceptions, these plants (herbaceous or woody) are found in standing water or seasonally saturated soils (14 or more consecutive days) near the surface.
Facultative
Wetland FACW
Usually occur in wetlands but may occur in non-wetlands. These plants predominantly occur with hydric soils, often in geomorphic settings where water saturates the soils or floods the soil surface at least seasonally.
Facultative FAC
Occur in wetlands and non-wetlands. These plants can grow in hydric, mesic, or xeric habitats. The occurrence of these plants in different habitats represents responses to a variety of environmental variables other than just hydrology, such as shade tolerance, soil pH, and elevation, and they have a wide tolerance of soil moisture conditions.
Facultative
Upland FACU
Usually occur in non-wetlands but may occur in wetlands. These plants predominantly occur on drier or more mesic sites in geomorphic settings where water rarely saturates the soils or floods the soil surface seasonally.
Upland UPL
Almost never occur in wetlands. These plants occupy mesic to xeric non-wetland habitats. They almost never occur in standing water or saturated soils. Typical growth forms include herbaceous, shrubs, woody vines, and trees.
Vernal Pools
Jurisdictional Delineation
TPM 38174, City of Riverside, Riverside County, CA July 2022 QUIN-05-752.JD2 (CEQA) 12 L&L
During our investigation, the property was searched for vernal pools. To meet the definition of a vernal pool three (3) factors must be addressed: (1) suitable soil and soil conditions, (2) proper hydrology, and (3) one or more indicator species.
Nomenclature Used
Terminology has changed over the years. Toward greater clarity and understanding, L&L uses terms in this report that follow CDFW, RWQCB, and MSHCP guidelines both published and expressed. We also describe linear features or channels as Streambeds (CDFW) and State Waters (RWQCB) and Wetlands as habitat areas meeting any one (1) of the three (3) criteria of appropriate hydrology, hydric soils , or hydric vegetation. Within the MSHCP (Plan) area state drainages are also considered riverine habitat and woody wetland vegetation is considered riparian.

4.0) RESULTS
4.1) Soils
Topographically, the site is hilly and generally slopes downward from northeast to southwest. The northwestern portion of the site and the southeastern corner are relatively flat, sloping downward towards the drainage present onsite. The elevation onsite ranges from 1279 feet (390 meters) above mean sea level (AMSL) in the southwest corner to 1334 feet (407 meters) AMSL in the northeast corner. An area of lower elevation between the eastern corners of the parcel contains the onsite drainage feature.
Soil Survey Geographic (SSURGO) Database shapefiles and Web- Soils identify soils onsite as Buren fine sandy loam, Cieneba rocky sandy loam, Hanford coarse sandy loam, and Terrace escarpments (Figure 5). All soils mapped on the property have a hydric rating of zero (Table 2).
Table 2. Mapped soils.

BuD2 Buren fine sandy loam, 8 to 15 percent slopes, eroded 0 CkF2 Cieneba rocky sandy loam, 15 to 50 percent slopes, eroded 0 HcC Hanford coarse sandy loam, 2 to 8 percent slopes 0
TeG Terrace escarpments 0
Hydric soils are defined by the National Technical Committee for Hydric Soils (NTCHS) as soils that formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part (Federal Register 1994). Under natural conditions, these soils are either saturated or inundated long enough during the growing season to support growth and reproduction of hydrophytic vegetation. https://websoilsurvey.sc. egov.usda.gov/App/WebSoilSurvey.aspx (accessed 10/11/2019).
The NTCHS definition identifies general soil properties that are associated with wetness. To determine whether a specific soil is a hydric soil or nonhydric soil more specific information, such as the depth and duration of the water table, is needed. Thus, criteria that identify those estimated soil properties unique to hydric soils have been established (Federal Register 2002). These criteria are used to identify map unit components that normally are associated with wetlands. The criteria used are selected estimated soil properties that are described in "Soil Taxonomy" (Soil Survey Staff 1999), "Keys to Soil Taxonomy" (Soil Survey Staff 2014), and the "Soil Survey Manual" (Soil Survey Division Staff 2017).

If soils are wet for long enough to be considered hydric, they should exhibit certain properties easily observed in the field. These visible properties are indicators of hydric soils and are specified in "Field Indicators of Hydric Soils in the United States" (Vasilas, Hurt, and Noble 2010).
Soils were examined in the field via test pit (Figure 6).
The project area had no rain for the 30 days preceding the site visit. Rainfall between October 2020 and August 2021 totaled 4.92 inches (http://agacis.rcc-acis.org/?fips=06065).
Soils on the surface of the ground were drained. No hydric soils or undisturbed vegetation was present in any of the streambeds.
4.2) Vegetation
The site has been historically utilized for residential, agricultural, and ranching purposes.
Recently disked open fields are present throughout the majority of the site. A house is present along the western boundary with associated landscape and ornamental trees are present along Alpine Meadows Lane. The remainder of the parcel is either regularly disked for weed abatement purposes or covered with Riversidean sage scrub.
The following vegetation alliance is present within or near to the drainage:
4.2.1) Encelia farinosa Shrubland Alliance
Brittlebush shrubland (Encelia farinose) is found on approximate one half of the site primarily within the southeast corner. Lower areas associated with the drainage also contain common sunflower (Helianthus anuus) and black mustard (Brassica nigra, see Figure 7).

4.2.2) Developed and Disturbed Lands
Developed and disturbed areas onsite include existing structures and paved, cleared, or graded land altered by human activities. This habitat community is estimated to occupy ±3.66 acres or 63% of the site.
Non-native trees and other ornamental landscape shrubs are present in association with the onsite residence and areas along the driveway and road (Alpine Meadows Lane).
4.2.3) Vernal Pool
Soil types are not consistent with an alkali playa or vernal pool complex and pools or depressions characteristic of vernal pool habitat were not noted as present on the subject property. Soils are well drained and slopes present prevent pooling from occurring onsite.
Vernal pools are defined as:
“. . . seasonal wetlands that occur in depression areas that have wetlands indicators of all three parameters (soils, vegetation and hydrology) during the wetter portion of the growing season but normally lack wetlands indicators of hydrology and/or vegetation during the drier portion of the growing season. Obligate hydrophytes and facultative wetlands plant species are normally dominant during the wet ter portion of the growing season, while upland species (annuals) may be dominant during the drier portion of the growing season.
4.3) Site Specific Hydrology
The U. S. Geological Survey (USGS) the U. S. Fish and Wildlife Service (USFWS) Wetland Mapper shows one (1) Riverine feature a few hundred feet south of the property; however, none are mapped onsite. An unnamed feature crosses under Kingdom Drive and enters the parcel in the middle of the eastern boundary. Periodic flows cross the eastern half of the parcel, flowing southwest before leaving the site (https://www.fws.gov/wetlands/Data/Mapper.html).
The parcel is within Zone X , an area of minimal flood hazard (FIRMette Map - https://msc.fema.gov/portal/search?AddressQuery=841%20ALPINE%20MEADOWS%20LANE %2C%20Riverside%2C%20Riverside%20County%2C%20CA#searchresultsanchor). Prenda Dam (a flood control facility) is located a few hundred feet west of the project area.

The average high temperature in Riverside in the summer is around 94 degrees and the average low in the winter is 42 degrees. Precipitation averages 11 inches per year (https://www.bestplaces.net/climate/city/california/riverside).
4.4.2) Precipitation
Information is available from Natural Resources Conservation Service Wetlands Climate Tables (NRCS WETS) for Riverside County, Riverside 5.8 E, CA (CoCoRaHS). The project area had no rain during the 30 days preceding the site visit. L&L concluded from this information that if hydric conditions were to exist onsite some form of evidence would be present during the field surveys (http://agacis.rcc-acis.org/?fips=06065).

4.5) Description of Drainages
4.5.1) Streambed/Riverine 1
Streambed / Riverine Feature 1 is 20,222 sq. ft. is unvegetated and disturbed or contains upland vegetation with an average width of 6.625 feet. Of the present 3,834.40 Sq. Ft. with an average width of 5.863, this feature qualifies as Non- wetland Waters of the United States at the federal level under jurisdiction of the USACE . Vegetation alongside the drainages includes mustard, tree tobacco and brittlebush.
At the time of the field visit soils were completely dry and no water was observed. An examination of Google Earth images accessed while conducting the site visit indicated the presence of discrete flows. The feature lacks any of the three (3) criteria necessary for wetland status at the state level. This feature consists of state streambed and MSHCP riverine habitat (Tables 5a and 5b).

5.0) CONCLUSIONS
L&L found jurisdictional “waters of the state” present within the site. "Waters of the state" means any surface water or groundwater, including saline waters, within the boundaries of the state (Water Code Section 13050[e]). Jurisdictional streambeds or drainages that connect to downstream flows are also jurisdictional.
L&L found jurisdictional “waters of the US” present within the site. Until the Navigable Waters Protection Rule takes effect, the Step One rule is in effect. 40 CFR 230.3(s) indicates tha t the term “waters of the United States” means:
1. All waters which are currently used, or were used in the past, or may be susceptible to use in interstate or foreign commerce, including all waters which are subject to the ebb and flow of the tide;
2. All interstate waters including interstate wetlands;
3. All other waters such as intrastate lakes, rivers, streams (including intermittent streams), mudflats, sandflats, wetlands, sloughs, prairie potholes, wet meadows, playa lakes, or natural ponds, the use, degradation or destruction of which could affect interstate or foreign commerce including any such waters:
a. Which are or could be used by interstate or foreign travelers for recreational or other purposes; or
b. (From which fish or shellfish are or could be taken and sold in interstate or foreign commerce; or
c. Which are used or could be used for industrial purposes by industries in interstate commerce;
4. All impoundments of waters otherwise defined as waters of the United States under this definition;
5. Tributaries of waters identified in paragraphs (s)(1) through (4) of this section;
6. The territorial sea;
7. Wetlands adjacent to waters (other than waters that are themselves wetlands) identified in paragraphs (s)(1) through (6) of this section.
Waste treatment systems, including treatment ponds or lagoons designed to meet the requirements of CWA (other than cooling ponds as defined in 40 CFR 423.11(m) which also meet the criteria of this definition) are not waters of the United States.
Waters of the United States do not include prior converted cropland. Notwithstanding the determination of an area’s status as prior converted cropland by any other federal agency, for the purposes of the Clean Water Act, the final authority regarding Clean Water Act jurisdiction remains with EPA. Definition of "Waters of the United States" under the Clean Water Act | US EPA.

TPM 38174, City of Riverside, Riverside County, CA July 2022 QUIN-05-752.JD2 (CEQA) 27 L&L
Wetland areas within or adjacent to features are regulated by the state of California where they exhibit any one (1) of the three (3) parameters (water modified soils, facultative vegetation, or surface or subsurface water).
L&L found state streambeds present within the site. FGC Section 1602 states: (a) An entity shall not substantially divert or obstruct the natural flow of, or substantially change or use any material from the bed, channel, or bank of, any river, stream, or lake, or deposit or dispose of debris, waste, or other material containing crumbled, flaked, or ground pavement where it may pass into any river, stream, or lake, unless all of the following occur:
All jurisdictional delineations conducted by consultants are considered preliminary until verified and accepted or acted upon by the agencies.
Total Resources
L&L found 20,222 sf (0.46 acre) of CDFW streambeds of which 20,222 (0.46 acre) is also subject to Section 6.1.2 of the MSHCP. L&L found 3,834.40 sf (0.088 acre) subject to the USACE jurisdiction. No state or federal wetlands are present. No vernal pools or vernal pool species are present.
Project Impacts
No impact to CDFW streambeds or waters is planned. No impact to USACE “waters” is planned.
Not impact to MSHCP riverine habitat is planned nor will occur as a result of the development of the project as proposed (Figure 9). No impact to state or federal wetlands or MSHCP riparian habitat is planned as none are present on the site.
