Refuge Palm Desert Project Biological Resources Assessment & MSHCP Compliance Report March 2022 1 1.0 INTRODUCTION At the request of Terra Nova Planning and Research, Inc., this biological resources assessment & Coachella Valley Multiple Species Habitat Conservation Plan (CVMSHCP) compliance report was prepared by Wood Environment & Infrastructure Solutions, Inc. (Wood) for the proposed Refuge Palm Desert Project (project) in the City of Palm Desert, Riverside County, California. The approximately 105-acre project site is located immediately south of Gerald Ford Drive. The nearest major streets to the east, south, and west are respectively Portola Road, Frank Sinatra Drive, and Monterey Avenue (Figure 1). The site is located within Section 32 of Township 4 South, Range 6 East of the United States Geological Survey (USGS) 7.5’ Cathedral City, CA and Myoma, CA quadrangles. Onsite elevation ranges from approximately 275 – 305 feet (84 – 93 meters) above mean sea level (Figure 2). The project site is on assessor’s parcel numbers (APN) 694-310-002, -003, and -006. The project proposes the construction of 504 homes, see the conceptual site plan (Appendix 1). Information contained herein is intended to be used for compliance with state and federal regulations intended to protect waters, wildlife, special status elements, and their habitats. 2.0 REGULATORY FRAMEWORK Several relevant biological and environmental regulations have been included in this section, but the CVMSHCP is the primary regulatory entity for this project. 2.1 Coachella Valley Multiple Species Habitat Conservation Plan Finalized in October 2008, the CVMSHCP is a comprehensive regional plan that addresses the conservation needs of 27 species of native flora and fauna and 27 natural vegetation communities occurring throughout the Coachella Valley region of western Riverside County, California (Coachella Valley Association of Governments [CVAG] 2021). Permits for the CVMSHCP were issued by the California Department of Fish and Game (CDFG) [now the California Department of Fish and Wildlife (CDFW)] on September 9, 2008 and the United States Fish and Wildlife Service (USFWS) on October 1, 2008 (TE104604-0). The CVMSHCP serves two primary purposes: balancing environmental protection and economic development objectives in the CVMSHCP area and simplifying compliance with endangered species related laws. The CVMSHCP accomplishes this by conserving unfragmented habitat to permanently protect and secure viable populations of the covered species. The covered species include plants and animals that are either currently listed as threatened or endangered, are proposed for listing, or are believed by an USFWS and CDFW appointed Scientific Advisory Committee, to have a high probability of being proposed for listing in the future if not provided protection by the CVMSHCP. The goal of the CVMSHCP is to meet the requirements of the state and federal endangered species acts, while at the same time allowing for the economic growth (land development) within the CVMSHCP area without significant delay or hidden costs. Under the CVMSHCP, mitigation is required from all new development projects Path: \\sdg1-fs1\gis\3554_NaturalResources\TerraNova_PalmDesertRefuge_322520120\MXD\ReportFigures\Fig1_Regional.mxd, aaron.johnson 3/10/2022 1 inch = 2 miles 0 21Miles° Service Layer Credits: Sources: Esri, HERE, Garmin, USGS, Intermap, INCREMENT P, NRCan, Esri Japan, METI, Esri China (Hong Kong), Esri Korea, Esri (Thailand), NGCC, (c) FIGURE 1 Regional MapRefuge Palm Desert ProjectRiverside County, California Project Boundary Refuge Palm Desert Project Biological Resources Assessment & MSHCP Compliance Report March 2022 3 This Page Intentionally Left Blank Path: \\sdg1-fs1\gis\3554_NaturalResources\TerraNova_PalmDesertRefuge_322520120\MXD\ReportFigures\Fig2_USGS.mxd, aaron.johnson 3/10/2022 1 inch = 2,000 feet 0 2,0001,000 Feet° Service Layer Credits: Copyright:© 2013 National Geographic Society, i-cubed FIGURE 2 USGS 7.5' Topo Quad: Cathedral CityRefuge Palm Desert ProjectRiverside County, California Project Boundary Refuge Palm Desert Project Biological Resources Assessment & MSHCP Compliance Report March 2022 5 This Page Intentionally Left Blank Refuge Palm Desert Project Biological Resources Assessment & MSHCP Compliance Report March 2022 6 occurring in the CVMSHCP area for the purpose of assembling a preserve system for the covered species and natural vegetation communities within areas identified as having high conservation value. Federal approval for the CVMSHCP was achieved under the Endangered Species Act (FESA or Act). The USFWS and the National Marine Fisheries Service are the designated federal agencies accountable for administering the FESA. FESA defines species as “endangered” or “threatened” and provides regulatory protection at the federal level. Section 10(a) of the FESA authorizes the issuance of incidental take permits and establishes standards for the content of habitat conservation plans, such as the CVMSHCP. State approval for the CVMSHCP was under the Natural Community Conservation Planning (NCCP) Program, managed by the CDFW. NCCPs are intended to conserve multiple species and their associated habitats, while also providing for compatible use of private lands. Through local planning, the NCCP planning process is designed to provide protection for wildlife and natural habitats before the environment becomes so fragmented or degraded by development that species listings are required under the California Endangered Species Act (CESA). Instead of conserving small, often isolated “islands” of habitat for just one listed species, agencies, local jurisdictions, and/or other interested parties have an opportunity through the NCCP to work cooperatively to develop plans that consider broad areas of land for conservation that would provide habitat for many species. Partners enroll in the programs, and, by mutual consent, areas considered to have high conservation priorities or values are set aside and protected from development. Partners may also agree to study, monitor, and develop management plans for these high value “reserve” areas. The NCCP provides an avenue for fostering economic growth by allowing approved development in areas with lower conservation value. The Coachella Valley NCCP is included as a part of the CVMSHCP. 2.2 Protection of Migratory Birds 2.2.1 Migratory Bird Treaty Act The Migratory Bird Treaty Act (MBTA) signed by the U.S., Great Britain, Mexico, Japan, and the countries of the former Soviet Union make it unlawful to pursue, capture, kill, and/or possess, or attempt to engage in any such conduct to any migratory bird, nest, egg or parts thereof listed in the MBTA document (USFWS 2022). The Secretary of the Interior can issue permits for incidental take of migratory bird species. As with the FESA, the MBTA also allows the Secretary of the Interior to grant permits for the incidental take of these protected migratory bird species. The USFWS permit for the CVMSHCP allows only for the take of covered bird species which are also listed under the FESA, as amended and which are also listed under the MBTA. For other birds protected by the MBTA, and not listed under the FESA, no take is authorized (including killing and wounding of any such birds or take of eggs and active nests). Take is defined as “to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, collect, or attempt to engage in such conduct.” Refuge Palm Desert Project Biological Resources Assessment & MSHCP Compliance Report March 2022 7 2.2.2 Section 3503, 3505.5, & 3513 of the State Fish and Game Code Section 3503 makes it unlawful to take, possess, or needlessly destroy the nest or eggs of any bird. Section 3505.5 makes it unlawful to take, possess, or destroy any birds in the order Falconiformes or Strigiformes (birds-of-prey, i.e.: owls, hawks, eagles, etc.) or to take, possess, or destroy the nest or eggs of any bird-of-prey. Section 3513 makes it unlawful to take or possess any migratory nongame bird as designated in the MBTA. See California Legislative Information (2022). 2.3 Waters of the United States and the State of California Impacts to federal and state jurisdictional waters are not covered by the CVMSHCP. 2.3.1 United States Army Corps of Engineers (USACE) The USACE regulates the discharge of dredged or fill material in Waters of the United States (WUS) pursuant to Section 404 of the Clean Water Act (CWA). 2.3.2 Regional Water Quality Control Board (RWQCB) The RWQCB regulates activities pursuant to Section 401(a)(1) of the CWA. Section 401 of the CWA specifies that certification from the State is required for any applicant requesting a federal license or permit to conduct any activity including, but not limited to, the construction or operation of facilities that may result in any discharge into navigable waters. Through the Porter Cologne Water Quality Control Act, the RWQCB asserts jurisdiction over Waters of the State of California (WSC) which is generally the same as WUS but may also include isolated waterbodies. The Porter Cologne Act defines WSC as “surface water or ground water, including saline waters, within the boundaries of the state”. 2.3.3 California Department of Fish and Wildlife The CDFW regulates water resources under Section 1600-1616 of the California Fish and Game Code. Section 1602 states: “An entity may 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.” Refuge Palm Desert Project Biological Resources Assessment & MSHCP Compliance Report March 2022 8 3.0 METHODS 3.1 Literature Review In preparation for the field visit, a literature search was conducted to identify special status biological resources known from the vicinity of the site. In the context of this report, and for the purpose of this assessment, vicinity is defined as areas within a five-mile radius of the site. The literature review included the following documents:  California Natural Diversity Data Base (CNDDB) RareFind 5 (CDFW 2022a)  California Native Plant Society's (CNPS) Inventory of Rare, Threatened, and Endangered Plants of California (CNPS 2022)  CVMSHCP (CVAG 2022)  United States Department of Agriculture (USDA), Natural Resources Conservation Service (NRCS). 2019. Web Soil Survey  USGS 7.5’ Cathedral City, Myoma, Rancho Mirage, and La Quinta, CA quadrangles This document utilized the following standard references: for plant communities, the CVMSHCP (2022); for flora, the Jepson Flora Project (2022) and USDA NRCS PLANTS Database (2022); for amphibians, reptiles, and mammals, CDFW (2016); and for birds, the California Bird Records Committee (2022). 3.2 Field Assessment The field assessment was conducted on 7 March 2022 by Wood Senior Biologist John F. Green. General weather and site conditions were recorded at the beginning and end of the assessment. Temperatures and wind speeds were recorded with a handheld Kestrel anemometer. Temperatures during the 0830-1135 site visit ranged from 64 to 67 degrees Fahrenheit with winds from 0 to 5 miles per hour under nearly clear skies. Suitable habitat was assessed based on the presence or absence of habitat components (e.g., soils, vegetation and topography) characteristic of special status biological resources which were determined by the literature review to be potentially present. Pedestrian transects were walked around the entire site. All flora and fauna observed or otherwise detected (e.g., dead remains [primarily plants], vocalizations, presence of scat, tracks, and/or bones) during the assessment were recorded in field notes and are included in Appendices 2 and 3. Plant species of uncertain identity were photographed for identification. Photos representing general site conditions were taken at various points (Appendix 4). Refuge Palm Desert Project Biological Resources Assessment & MSHCP Compliance Report March 2022 9 4.0 RESULTS The project site is largely undeveloped, but not entirely undisturbed. The surrounding area is almost entirely developed with a golf course, sheriff’s station, and residences immediately adjacent to the site. Active construction is underway on the east project boundary where the largest remaining adjoining undeveloped land had been. These adjacent developments have caused edge effects to the project site such as construction disturbance; intrusion of landscaping vegetation; growth of atypical native vegetation around site margins due to adjacent irrigation; trash and debris; and site entry by vehicles, domestic dogs, and pedestrians. Drift fencing presumably meant to control blow-sand were also installed onsite. Only one small area adjacent to the northeastern-most portions of the site remains undeveloped and in similar condition to the project area (Figure 3). 4.1 Hydrology / Jurisdictional Waters There are no drainages or jurisdictional features onsite. Therefore, there will be no further discussion of hydrology or jurisdictional waters. 4.2 Topography and Soils The project site is covered with a surprising amount of blow-sand for a location so isolated by development. It forms small dunes in some areas and has also overtopped the golf course wall at some points. Some areas have lost sand depth or stabilized around athel trees or other obstacles. The Web Soil Survey (USDA, NRCS 2019) shows the following soil types on the site (Figure 4):  Myoma fine sand, 0 - 5% slopes  Myoma fine sand, 5 to 15 percent slopes Myoma soils are somewhat excessively drained with very slow runoff and rapid permeability. They are moderately alkaline fine and very fine sands which formed in sand blown from recent alluvium. Slopes are level to rolling. Sandy soils are associated with several potentially occurring special status species. 4.3 Vegetation A review of vegetation communities described by the CVMSHCP (natural communities) revealed “stabilized and partially stabilized desert dunes” as the community matching the physical and vegetative parameters of the site (Figure 5). This community is described as: “sand dune accumulations that are stabilized or partially stabilized” and “characterized by prominent dune features, with consistent cover of vegetation. This community may intergrade with” “stabilized and partially stabilized desert sand fields” and “includes perennial plant species typical of a creosote bush scrub matrix, with perennial shrub species including creosote bush (Larrea tridentata), four-wing saltbush (Atriplex canescens), California croton (Croton californicus), and indigo bush (Psorothamnus sp.).” All of these species occur onsite.

A list including common and scientific names, is attached (Appendix 2). Seventeen were native (74%). It should be noted that short-term biological studies of this nature are limited by the seasonality of plants and the timing of field visits. Drought conditions have likely limited the number of annuals as well as stunted those that have germinated. 4.4 Wildlife Vertebrate wildlife directly observed and/or detected otherwise (e.g., scat, bones, prints, feathers, burrows, etc.) during the assessment included a minimum of 19 species. This included two reptiles, 14 birds and at least three mammals. See Appendix 3 for a list of the species detected. It should be noted that short-term biological studies of this nature are limited by seasonality (for example migratory birds and “hibernating” mammals and reptiles), the fossorial and nocturnal habits of many mammals and reptiles, and the timing of field surveys. A complete inventory of the wildlife on the site would require extensive year-round surveys for invertebrates, amphibians, reptiles, birds, and mammals including, for example: diurnal netting/collecting and nocturnal black light traps for invertebrates, pitfall traps for amphibians and reptiles, and live trapping and/or the placement of tracking stations for the detection of nocturnal mammals. 4.5 Special Status Elements Plant or animal taxa may be considered "sensitive" or as having “special status” due to declining populations, vulnerability to habitat change, or because they have restricted ranges. Some are listed as threatened or endangered by the USFWS or by the CDFW and are protected by the FESA and/or CESA. Others have been identified as sensitive or as special status species by the USFWS, the CDFW, or by private conservation organizations, including the CNPS. Unlisted sensitive species do not have formal state or federal status but impacts to these species (if any) may nevertheless be considered significant. Knowledge of habitat associations, natural history, seasonality, and distribution is essential in the assessment of the potential for occurrence of the various sensitive plants and animals known to occur throughout the region. This knowledge, along with the literature review and site reconnaissance resulted in the identification of 43 special status elements which were either observed on the site, had CNDDB records within an approximate five-mile radius of the site, and/or which have potentially suitable habitat on the site. These included 18 plants, one vegetation community, five insects, one fish, two reptiles, nine birds, and seven mammals. Tables 1 through 7 provide a complete list of these sensitive biological resources, their associated status, their general habitat associations, and their respective site occurrence potential based on geographic distribution, the presence of potentially suitable habitat, and the collective expertise of Wood biologists.

Its goals are (1) to facilitate communication among interested parties and reduce risks of species decline or extinction; (2) to provide a mechanism by which current information on bat ecology, distribution and research techniques can be readily accessed; and (3) to develop a forum to discuss conservation strategies, provide technical assistance and encourage education programs. H: High: Species which are imperiled or are at high risk of imperilment based on available information on distribution, status, ecology and known threats. M: Medium: Species which warrant a medium level of concern and need closer evaluation, more research, and conservation actions of both the species and possible threats. A lack of meaningful information is a major obstacle in adequately assessing these species' status and should be considered a threat. L: Low: Species for which most of the existing data support stable populations, and for which the potential for major changes in status in the near future is considered unlikely. There may be localized concerns, but the overall status of the species is believed to be secure. Conservation actions would still apply for these bats, but limited resources are best used on High and Medium status species. P: Periphery: This designation indicates a species on the edge of its range, for which no other designation has been determined. 4.6 CVMSHCP Conservation Areas The project site is not within or adjacent to any CVMSHCP conservation areas (Figure 6), so it is not subject to conservation area guidelines. Therefore, there will be no further discussion of CVMSHCP conservation areas.

Of the remaining 32 species which have some occurrence potential, nine are fully covered and conserved through participation in the CVMSHCP: Coachella Valley milk-vetch, Mecca-aster, Coachella giant sand treader cricket, Coachella Valley Jerusalem cricket, flat-tailed horned lizard, Coachella Valley fringe-toed lizard, western yellow bat, Palm Springs pocket mouse, and Coachella Valley (Palm Springs) round-tailed ground squirrel. Since potential impacts to these nine species will be mitigated through participation in the CVMSHCP they will not be discussed further. The remaining 23 species are discussed below. 5.1.1 Plants Thirteen special status plant species not covered by the CVMSHCP have potential to occur onsite: chaparral sand-verbena, gravel milk-vetch, pointed dodder, glandular ditaxis, California ditaxis, Abram’s spurge, Arizona spurge, flat-seeded spurge, ribbed cryptantha, Torrey’s box- thorn, slender cottonheads, narrow-leaved sandpaper plant, and Mecca-aster. None are state or federally listed as endangered or threatened. The site is isolated by development, becoming a small island of habitat. Research has shown that such sites tend to lose biodiversity over time, so even if any of these plant species persist now, they are likely to decline and be lost even if the site were to remain undeveloped. Given this, we do not anticipate the presence of any populations of significance. Since the project site is not within or immediately adjacent to a conservation area, no additional pre-construction surveys are required. 5.1.2 Insects Two insects not covered by the CVMSHCP have potential to occur on-site: Crotch bumble bee and cheeseweed owlfly. Neither is state or federally listed as endangered or threatened. For the reasons outlined in Section 5.1.1, even if present these species would not be expected to persist in the long term. We do not anticipate the presence of any populations of significance. Since the project site is not located within a conservation area and the project site is not likely to contain any long-term beneficial use for these species, no additional surveys are required. 5.1.3 Burrowing Owl The burrowing owl is a covered species under the CVMSHCP, but the federal permit for the CVMSHCP does not allow take of this species under the MBTA. This species nests and roosts underground and is thus particularly vulnerable to ground disturbing activities. Marginal habitat is present onsite for the owl, but the isolated nature of the site and limited burrowing opportunities observed make the possibility of occurrence quite low. Nevertheless, to avoid take of the burrowing owl the “CDFW recommends two take avoidance surveys. The first should Refuge Palm Desert Project Biological Resources Assessment & MSHCP Compliance Report March 2022 28 occur between 14 and 30 days prior to ground disturbance and the second within 24 hours of ground disturbance” (CDFG 2012, CDFW 2014). 5.1.4 Non-Nesting Special Status Bird Species Potentially Occurring Prairie falcon and willow flycatcher (southwestern and other subspecies) could occur onsite as migrants and/or foragers, but no nesting habitat is available. We do not recommend any further action regarding these species. 5.1.5 Special Status Bird Species The Costa’s hummingbird, loggerhead shrike, black-tailed gnatcatcher, vermilion flycatcher, and LeConte’s thrasher are all special status species which may nest onsite and in the project area. Costa’s hummingbird was present onsite during the field assessment. Of these five, only the LeConte’s thrasher is covered by the CVMSHCP. Regardless of their status, all are protected from take by the MBTA and state code. Nesting bird surveys for compliance with the MBTA and state code will prevent impacts to these species. This will be discussed further below. 5.2 Migratory Bird Treaty Act (MBTA) and State Code Virtually all native migratory and resident bird species, including many of the birds already known to occur in the vicinity (Appendix 3) are protected by the MBTA and state code. Avoidance of impacts to nesting migratory and resident birds is a requirement of the federal permit issued for the CVMSHCP. In order to avoid impacting nesting birds, either avoidance of project-related disturbance during the nesting season (generally from approximately 1 February to 31 August) or nesting bird surveys conducted by a qualified ornithologist or biologist immediately prior to site disturbance during the nesting season would be required. If an active nest is detected, a buffer would be established around it and no work would be permitted in that area near the nest until young have fledged. While there is no established protocol for nest avoidance, when consulted, the CDFW generally recommends avoidance buffers of about 500 feet for birds-of-prey and listed species, and 100 – 300 feet for unlisted songbirds. These measures will protect nesting birds, including the potentially occurring special status species. 5.3 Special Status Mammals Only one special status mammal not covered by the CVMSHCP was identified as being of potential occurrence: pallid San Diego pocket mouse. The possibility of occurrence is low, as the site is likely beyond the edge of this species’ range. Because of that, and for the reasons outlined in Section 5.1.1, even if present this species would not be expected to persist in the long term. We do not anticipate the presence of any population of significance and have no further recommendations. Refuge Palm Desert Project Biological Resources Assessment & MSHCP Compliance Report March 2022 29 6.0 CONCLUSION Implementation of the proposed project would result in permanent impacts to the project site (see Appendix 1) including the biological resources occurring or potentially occurring in the impacted area. Project impacts will be mitigated through participation in the CVMSHCP. CVMSHCP landscaping suggestions are included in Appendices 5 and 6. With the implementation of the recommendations in this report, impacts to special-status species potentially occurring in the project area and their habitats would be expected to be less than significant. Recommendations include pre-construction surveys for burrowing owl and MBTA protected nesting birds.
