The proposed private horse keeping and grape planting project will develop the entire 42.8-acre site and result in significant impacts to approximately 20.1 acres of sensitive Diegan coastal sage scrub and 14.6 acres of non-native grassland, a pair of coastal California gnatcatchers, two coastal whiptails, two kestrels, red-tailed hawk, turkey vulture, and Cooper’s hawk. These impacts will be significant and require mitigation. Mitigation for habitat impacts will be provided by purchasing 40.2 acres of coastal sage scrub and 7.3 acres of non-native grassland in Daley Ranch Conservation Bank. Mitigation for impacts to the wildlife species will be provided through habitat-based mitigation, for which the coastal sage scrub and non-native grassland mitigation will be adequate. These mitigation measures, in conjunction with standard avoidance measures such as avoiding grading during avian breeding season, will reduce the project’s impacts to below a level of significance. Because the coastal sage scrub on-site is occupied, a Habitat Loss Permit will be required.

INTRODUCTION, PROJECT DESCRIPTION, LOCATION, SETTING

The proposed project (“Project”) consists of grading the site in order to develop a private horse keeping facility and a non-commercial grape-growing area. The Project site has been the subject of past approved land uses. Specifically, it was mined for gravel, and it was approved and partially developed with three house pads, around which fuel management zones are maintained. As part of the permitting process for another proposed grading plan, Everett and Associates performed a California gnatcatcher protocol survey and prepared a survey report in 2006 and

March 2015 Private Horse Keeping and Grape Planting REC Consultants, Inc. Biological Resources Letter Report

prepared a biological technical report in 2007 (Everett 2007), and a Habitat Loss Permit (HLP 06-004, June 2008) was issued for proposed impacts to 20 acres of coastal sage scrub on-site.

Project Description The Project involves grading the site and constructing two grape-growing areas, a barn, a horse pen, a private horse arena, and a pasture. No off-site impacts are anticipated.

Project Location and Setting The Project site is located on Assessors’ parcel numbers 228-400-022, 228-400-016, and 232- 030-015 within the County of San Diego, between the City of San Marcos and the City of Escondido. This location is approximately 0.3 mile south of State Route 78, 1 mile west of Interstate 15, and southwest of the intersection of Country Club Lane and Auto Park Way. A map of the regional location is provided in Figure 1, and the site location and vicinity are illustrated on United States Geological Survey (USGS) 7.5’ topographic quadrangle map(s) in Figure 2. This location occurs at the intersection of four USGS 7.5’ quadrangle maps: San Marcos, Rancho Santa Fe, Escondido, and Valley Center.

The site is bordered by residential development, Country Club Drive, and industrial development to the north; residential development and the new Palomar Medical Center to the east; an undeveloped field and then residential development to the south; and fields, residential, and light industrial development to the west.

The site includes steeply to gently sloping terrain, with a high point of roughly 900 feet above mean sea level (AMSL) at a hilltop near the eastern boundary, sloping down toward the southwest to a low of roughly 710 feet AMSL along the southwestern side. An inactive gravel pit is located in the hillside in the northern part of the site.

According to the Soil Survey, San Diego Area, California (Bowman 1973), the following soil types are present on-site: Vista coarse sandy loam, 5 to 9% slopes, 9 to 15% slopes, and 15 to 30% slopes; and Cieneba coarse rocky sandy loam, 9 to 30%, eroded. The Vista series consists of well-drained, moderately deep and deep coarse sandy loams derived from granodiorite or quartz granodiorite within elevational ranges of 300 to 2,500 feet. The Cieneba series consists of excessively drained, very shallow to shallow coarse sandy loams formed in materials weathered in place from granitic rock on rolling to mountains uplands, at elevations of 500 to 3,000 feet.

REGIONAL CONTEXT

The Project region (near the intersection of Interstate 15 and State Route 78) includes land within the jurisdictions of San Diego County, the City of Escondido, and the City of San Marcos. This area is rapidly urbanizing, especially to the southwest of the freeway interchange, where light industrial development is expanding. An aerial photograph showing the regional context of the Project site is provided in Figure 3.

The Project site is in north San Diego County, within the draft North County Multiple Species Conservation Program (MSCP), and is designated as outside any draft Pre-Approved Mitigation

March 2015 Private Horse Keeping and Grape Planting REC Consultants, Inc. 2 Biological Resources Letter Report

Area (PAMA). The closest draft PAMA is approximately one mile south along Escondido Creek, and the closest edge of the proposed core California gnatcatcher area is approximately 3.3 miles southwest.

Some private and County preserves have been created in the region, including the 774-acre Del Dios Highlands County Preserve, the 784-acre Elfin Forest Recreational Reserve (both more than 2.5 miles south-southwest of the Project), and areas managed by The Escondido Creek Conservancy, but the Project is not near these preserves or Escondido Creek. The Project site is located within the watershed of Escondido Creek, which drains to San Elijo Lagoon (SELC 2013), but the Creek is approximately one mile south of the Project site without direct connectivity.

HABITATS / VEGETATION COMMUNITIES

Existing biological resources on the Project site were investigated through field reconnaissance and literature review by REC biologists.

Literature review consisted of a search and review of CNDDB records of rare and special-status plant and animal species within the Project USGS 7.5’ quadrangles (Rancho Santa Fe, San Marcos, Valley Center, and Escondido), review of SanBIOS special-status animal records within a 5-mile radius of the site, review of the 2007 Everett and Associates biological resources report for the site (Everett 2007), recent and historical aerial photographs of the site and surrounding areas, and soil maps and descriptions from the United States Department of Agriculture (USDA) Soil Survey, San Diego Area, California (Bowman 1973).

A general survey of the Project site was conducted by a senior REC biologist and botanist, Catherine MacGregor, to document current biological resources, including plants, animals, and habitats; and separate focused site visits were conducted to confirm the presence of California gnatcatcher and survey wildlife on-site. Field notes were maintained by REC biologists throughout the surveys. All on-site habitats were mapped, and all observed plant and animal species were documented. Plant species that could not be identified in the field were collected for later identification, and wildlife species were identified directly by sight or vocalizations and indirectly by scat, tracks, burrows, or nests. All observed special-status species were documented and mapped, and suitability of habitat for special-status species was evaluated. Habitats and wildlife on surrounding adjacent off-site properties were observed from the site or public roadways, but no surveys were conducted on private property other than this Project site for this report. Mapping of existing resources on the Project site was conducted on an aerial photograph scaled at 1 inch = 200 feet.

Scientific nomenclature and common names for animal species in this letter report follow American Ornithological Union (AOU 2012) for birds, Center for North American Herpetology (CNAH 2013) for reptiles and amphibians, Baker et al. (2003) for mammals, and Powell and Hogue (1979) for insects, as well as the San Diego Natural History Museum butterfly, spider, amphibian, reptile, bird and mammal checklists for subspecies (SDNHM 2002, 2005, and undated). Taxonomy and scientific nomenclature for plants follow the Jepson Manual, second edition (Baldwin et al. 2012) and common names are primarily from Rebman and Simpson

During REC’s site surveys, two vegetation communities/habitats and two other land cover categories were observed: coastal sage scrub, non-native grassland, disturbed land, and developed land; these habitats are shown in Figure 4 and are described below. A complete list of all plants observed during REC’s 2013 surveys is provided in Appendix A.

Diegan coastal sage scrub (County Habitat Code 32500) covers approximately 20.1 acres on hillsides and gentle slopes on-site. This coastal sage scrub is dominated by coastal sagebrush (Artemisia californica) and California buckwheat (Eriogonum fasciculatum var. fasciculatum and var. foliolosum) on the north-, west-, and east-facing slopes, and by black sage (Salvia mellifera) on the south-facing slope. Other native members of the sage scrub community on-site include deerweed (Acmispon glaber), laurel sumac (Malosma laurina), coast monkey flower (Mimulus aurantiacus var. puniceus), long-stem golden-yarrow (Eriophyllum confertiflorum var. confertiflorum), cryptantha (Cryptantha sp.), sand aster (Corethrogyne filaginifolia), chalk Dudleya (Dudleya pulverulenta) and prickly-pear (Opuntia sp.). Rock outcrops in the coastal sage scrub shelter other herbs and ferns such as Nuttall’s snapdragon (Antirrhinum nuttalianum), caterpillar phacelia (P. cicutaria var. hispida), California bee plant (Scrophularia californica), sticky silverback fern (Pentagramma triangularis subsp. viscosa) and California lace fern (Aspidotis californica). Areas of more disturbed coastal sage scrub, such as around the old gravel pit areas, contain higher numbers of disturbance-associated species such as broom baccharis (Baccharis sarothroides) and non-native species such as tree tobacco (Nicotiana glauca), African fountain grass (Pennisetum setaceum), sweet fennel (Foeniculum vulgare), and brome grasses (Bromus diandrus, B. madritensis subsp. rubens). Habitat quality varies from medium in less disturbed areas, to low where it has regenerated in a disturbed condition around areas of historic disturbance. Species diversity is moderately good in less disturbed areas but much poorer in more disturbed areas of scrub. It is likely that areas with more vegetative cover and/or greater species diversity provide better wildlife habitat. For a complete listing of plant species observed in coastal sage scrub on-site refer to Appendix A.

Wildlife species observed in coastal sage scrub on-site include coastal whiptail (Aspidoscelis tigris stejnegeri), western fence lizard, (Sceloporus occidentalis), American kestrel (Falco

March 2015 Private Horse Keeping and Grape Planting REC Consultants, Inc. 4 Biological Resources Letter Report

sparverius), Anna’s hummingbird (Calypte anna), Bewick’s wren (Thryomanes bewickii), black phoebe (Sayornis nigricans), bushtit (Psaltriparus minimus), California thrasher (Toxostoma redivivum), California towhee (Melozone crissalis), coastal California gnatcatchers (Polioptila californica californica), greater roadrunner (Geococcyx californianus), spotted towhee (Pipilo maculatus), western scrub-jay (Aphelocoma californica), Wilson’s warbler (Cardellina pusilla), wrentit (Chamaea fasciata), coyote (Canis latrans) (live and skeletons), cottontail (Silvilagus audubonii), and dusky-footed woodrat (Neotoma fuscipes) (middens only). A complete list of wildlife and estimated numbers is provided in Appendix B.

Diegan coastal sage scrub is considered sensitive by the County, State of California, and United States Fish and Wildlife Service. A Habitat Loss Permit (HLP) must be obtained from the County of San Diego before new impacts to this habitat on-site are permitted. The Project is not a discretionary action that is subject to the Resource Protection Ordinance (RPO), so coastal sage scrub on-site need not be evaluated for RPO Sensitive Lands status.

The coastal sage scrub on-site has little conservation value in terms of regional or local importance because it has become surrounded and isolated by suburban and light industrial development, and has been heavily disturbed by gravel mining and bicyclists and other trespassers, over the years. The nearest substantial blocks of undeveloped natural land are more than a mile to the west or southwest.

Non-native grassland (County Habitat Code 42200) covers approximately 14.6 acres on gently sloping portions of the site. The non-native grassland on-site is dominated by red brome (Bromus madritensis subsp. rubens) and ripgut brome (Bromus diandrus) with filaree (Erodium sp.), oats (Avena sp.), soft chess (Bromus hordeaceus), short-pod mustard (Hirschfeldia incana), and limited native species such as doveweed (Croton setiger), blue-eyed grass (Sisyrinchium bellum) and occasional coastal sage shrubs like deerweed and coastal sagebrush. Grass and forb cover is fairly dense. All plants observed in non-native grassland on-site are included in Appendix A.

Wildlife observed in and over non-native grassland on-site included black phoebe, black-headed grosbeaks (Pheucticus melanocephalus), lesser goldfinch (Spina psaltria), house finch (Haemorhous mexicanus), mourning dove (Zenaida macroura), northern mockingbird (Mimus polyglottos), western kingbird (Tyrannus verticalis), California ground squirrel (Spermophilus beecheyi), and cottontail. A turkey vulture (Cathartes aura) and a red-tailed hawk (Buteo jamaicensis) were observed flying over the non-native grassland. A complete list of wildlife and estimated numbers is provided in Appendix B.

This non-native grassland is considered sensitive by the County because of its importance for foraging raptors. The non-native grassland habitat on-site supports few of the native herbs that would make it more valuable wildlife habitat, such as bunchgrasses, blue-eyed grass, and herbaceous perennials from bulbs, and it has little conservation value because it is relatively small and isolated from larger habitat areas. The Project is not a discretionary action that is subject to the RPO, so non-native grassland on-site need not be evaluated for RPO Sensitive Lands status.

March 2015 Private Horse Keeping and Grape Planting REC Consultants, Inc. 5 Biological Resources Letter Report

Disturbed land (County Habitat Code 11300) occurs on approximately 7.6 acres of unpaved roads and trails, within fuel management zones around existing concrete house pads, and in and around the former gravel pit location. These areas of disturbed land have been repeatedly cleared, compacted, and impacted. Vegetation on most disturbed land is primarily weedy non- native species such as scarlet pimpernel (Anagallis arvensis), non-native annual grasses (Bromus spp., Avena spp.), Italian thistle (Carduus pycnocephalus subsp. pycnocephalus), tocalote (Centaurea melitensis), and globe chamomile (Oncosiphon piluliferum); or weedy native species such as horseweed (Erigeron canadensis) and telegraph weed (Heterotheca grandiflora). Plants observed growing on disturbed land on-site are included in Appendix A.

Wildlife observed on disturbed land included western fence lizard (Sceloporus occidentalis), greater roadrunner, and California ground squirrel (see Appendix B).

Developed land (County Habitat Code 12000) on-site consists of 0.5 acre on three existing concrete house pads and a paved section of driveway or access road at the northern entrance to the site. Although a few weedy plants may sprout from cracks in the concrete and pavement, this land cover category is essentially unvegetated. All plants observed growing on developed land on-site are included in Appendix A.

SPECIAL-STATUS SPECIES

For the purposes of this report, a sensitive or special-status plant or animal is any taxon (species, subspecies, or variety) that is officially listed by the State of California or the federal government as Endangered, Threatened, or Rare, or a candidate for one of those listings; classified as Fully Protected, Species of Special Concern, or Watch List animal species by CDFW; included in California Rare Plant Ranks (CRPR) 1 through 4; or included in the County of San Diego Sensitive Plant Lists A through D or Sensitive Animals Groups A or B.

Lists of special-status plants and animals with the potential to occur on the Project site were generated from the CNDDB RareFind5 database, SanBIOS database (County of San Diego 2011), and a list provided by the County of San Diego. The resulting lists include any special- status species documented within the Project site’s four USGS 7.5’ quadrangles (San Marcos, Rancho Santa Fe, Escondido, and Valley Center) within an applicable elevation range, as well as any other species requested by the County for this Project. Appendix C provides information on these special-status plant species, as well as an evaluation of the potential for each species to occur on-site, based on CNDDB search results, the CNPS Inventory of Rare and Endangered Plants (on-line version, 2013), Reiser’s Rare Plants of San Diego County (2001), professional botanical experience, and field observations. Appendix D provides information on these animal species, and an evaluation of the potential for each species to occur on-site, based on species requirements, CNDDB and SanBIOS search results, other biological reports conducted in this area, and field observations.

No special-status plants were observed on-site. One listed special-status animal and four other special-status animal species were observed on or over the site: coastal California gnatcatcher, coastal whiptail, American kestrel, red-tailed hawk, and turkey vulture.

March 2015 Private Horse Keeping and Grape Planting REC Consultants, Inc. 6 Biological Resources Letter Report

Coastal California gnatcatcher (Polioptila californica californica) is federally listed as Threatened and classified as a State of California Species of Special Concern. This small gray songbird is a year-round resident of coastal sage scrub in southwestern California from the Los Angeles Basin through Baja California, Mexico. California gnatcatcher populations have declined due to extensive conversion of Diegan coastal sage scrub habitat to urban and agricultural uses. A series of focused protocol surveys for the California gnatcatcher was completed by USFWS-permitted biologist William Everett (Permit TE-788036) in February and March of 2006, at which time one California gnatcatcher was detected on-site. A copy of the report from the 2006 California gnatcatcher survey is provided in Appendix E. An REC biologist visited the site in February 2013 to determine if California gnatcatcher was still present; during that non-protocol survey, a single California gnatcatcher was heard and visually confirmed at the location shown in Figure 4. During REC’s August 2013 wildlife survey (also non-protocol), a pair of California gnatcatchers was heard and visually confirmed in the northeastern coastal sage scrub, as shown in Figure 4. California gnatcatcher calls and one individual were also heard and seen at the northernmost edge of coastal sage scrub (~0.1 mile from observed pair location), a pair was heard calling near the central disturbed area (~0.1 mile from observed pair location), and one scolding call was heard at the western edge of the northwestern area of sage scrub (~0.2 mile from pair location); based on the short distances, it’s possible that these could all have been the same pair seen and heard in the northeastern part of the site.

Coastal whiptail (Aspidoscelis tigris stejnegeri) does not have federal or state special status but is included in the County’s Sensitive Animals List Group 2. This subspecies of the tiger whiptail occurs in coastal southern California, where much of its shrubland habitat has been developed or fragmented. Two tiger whiptails were observed on-site in 2013, darting under coastal sage scrub shrubs at the locations shown in Figure 4.

Turkey vulture (Cathartes aura) is not a state or federal special-status species, but is included in the County’s Sensitive Animals List Group 1. It is also protected as a raptor under California Fish and Game Code Section 3503.5, which specifically protects all birds in the orders Falconiformes or Strigiformes (raptors, including owls and turkey vultures). It is unlawful to take, possess or destroy any such raptors or their nests and eggs except as otherwise provided in the Fish and Game Code. Turkey vultures soar over dry open country such as coastal sage scrub, mixed and chamise chaparral, grassland, mixed conifer and closed cone forest habitats, as well as riparian habitat and roadsides, in search of the carrion upon which they feed. One turkey vulture was observed flying over the site at a height of about 75 feet.

American kestrel (Falco sparverius) is not a state or federal special-status species nor included on the County sensitive animal lists, but is protected as a raptor under California Fish and Game Code. Kestrels were observed foraging over coastal sage scrub and a non-native grassland on- site. A pair of kestrels was also observed off-site to the east, perched on a large power pole near the new hospital.

Red-tailed hawk (Buteo jamaicensis) is also neither a state nor federal special-status species nor included in the County sensitive animal lists, but is protected as a raptor under California Fish and Game Code. According to the San Diego Bird Atlas, red-tailed hawks are the most

March 2015 Private Horse Keeping and Grape Planting REC Consultants, Inc. 7 Biological Resources Letter Report

widespread bird of prey in San Diego County; they favor grassland with scattered trees but use all of the County's terrestrial habitat to some extent, and are even commonly seen perching on light poles along freeways. One red-tailed hawk was observed soaring high over the site in May 2013.

Raptor foraging and migratory birds:

The site serves as hunting ground for raptors. Kestrels were observed hunting over the coastal sage scrub and non-native grassland habitats, a turkey vulture flew low over the site, and a red- tailed hawk soared over the site. The site supports many prey animals such as ground squirrels, other rodents, and cottontail rabbits, as indicated by the number of live cottontails, rabbit scat, live ground squirrels, ground squirrel and other rodent burrows, and woodrat middens observed. As noted above, these raptors are protected under California Fish and Game Code Section 3503.5, which specifically protects all birds in the orders Falconiformes or Strigiformes.

California Fish and Game Code Section 3503 makes it unlawful to take, possess, or needlessly destroy the nest or eggs of any bird, except as otherwise provided by the Fish and Game Code or any regulation made pursuant to the Code, and the federal Migratory Bird Treaty Act prohibits the killing or transport of native migratory birds, or any part, nest, or egg or any such bird unless allowed by another regulation (such as for “game” birds), Therefore, all native, non-game birds (except for wrentit) on the Project site, and the nests and eggs of all native non-game birds, are protected during the nesting season even if these birds are not special-status or otherwise protected.

Special-status species with moderate to high potential to occur on or adjacent to the site

Based on CNDDB and SanBIOS records searches, review of the 2006 biological resources report, and evaluation of current site conditions, the following species have moderate to high potential to occur on-site:

Monarch butterfly (Danaus plexippus) is) is not a state or federal special-status species, but is included in the County’s Sensitive Animals List Group 2. No monarchs or their host plants (milkweeds, Asclepias spp.) were observed on-site, but it possible that milkweeds could have bloomed on-site and died before REC’s surveys, or that the site includes sufficient nectar plants to serve as a feeding area for monarchs. Monarchs are still somewhat widespread in San Diego County; therefore, they have moderate potential to occur on the Project site.

Orangethroat whiptail (Aspidoscelis hyperythra), a State of California Species of Special Concern and County Sensitive Animals List Group 2 species, lives in semi-arid brushy areas west of the Peninsular ranges, that typically have loose soil and rocks, including washes, rocky hillsides, and coastal chaparral and scrub. Because suitable habitat occurs on-site and the species is known to occur in the Project quadrangles, orangethroat whiptail has moderate potential to occur on the Project site.

Cooper’s hawk (Accipiter cooperii) is on the State of California Watch List and is included in the County’s Sensitive Animals List Group 1. One was documented flying over the site in 2006 as

March 2015 Private Horse Keeping and Grape Planting REC Consultants, Inc. 8 Biological Resources Letter Report

reported in the 2007 Everett and Associates biological resources report. Cooper’s hawks have adapted to urban and suburban settings and increased in abundance since the 1980s, and are now widespread over the San Diego County coastal slope wherever there are trees. Because the site and surrounding residential areas support eucalyptus trees and residential backyards likely to include bird feeders, Cooper’s hawk has high potential to forage on-site.

Sharp-shinned hawk (Accipiter striatus) is on the State of California Watch List and is included in the County’s Sensitive Animals List Group 1. This hawk is a widespread but uncommon winter visitor in San Diego County, especially along the coastal slope. It uses a variety of habitats, but prefers areas with trees or tall shrubs and is attracted to any place that concentrates small prey birds. Because the site is located next to residential properties that may have bird feeders, and because numerous trees and shrubs are present in the area, sharp-shinned hawk has moderate potential to use the site in winter.

Mexican long-tongued bat (Choeronycteris mexicana) is a State of California Species of Special Concern that, in California, is found in residential areas, and roosts in garages, sheds, porches, and under houses on stilts. This bat feeds on pollen and nectar, especially of agaves and columnar cacti. It will also visit hummingbird feeders and possibly avocado flowers. Because the land immediately around the site includes an abandoned home and other residences, and columnar cacti and agaves were observed in a yard adjacent to the east side of the site, the Mexican long-tongued bat has moderate potential to occur on the Project site.

Western yellow bat (Lasiurus xanthinus) is a State of California Species of Special Concern that most commonly occurs in desert palm oases, but is increasingly found in urban areas that have palm trees. This bat roosts in the hanging dead palm fronds and subsists on insects. Because the site and surrounding properties support numerous Mexican fan palms (Washingtonia robusta) and this species appears to be adapting to urban or suburban conditions, western yellow bat has moderate potential to occur on the Project site.

Large mammal use

No evidence of use by large mammals including mule deer (Odocoileus hemionus) and mountain lion (Puma concolor), such as scat or deer laydown areas, was found during REC’s 2013 surveys, nor were any large mammals reported in the 2007 biological resources report for the Project site. The site is likely too isolated and urbanized to support large mammals.

JURISDICTIONAL WETLANDS AND WATERWAYS

No jurisdictional wetlands or waters were found on the Project site. Two erosional features were examined for potential jurisdictional status through both on-site evaluation and off-site investigation of potential continuation to the west. These features likely formed from run-off after vegetation removal during past gravel mining activity, since each originates in a highly disturbed area. The more northern of the two contains an eroded channel with a section of bed and banks and supports a willow tree, but the channel completely fades away on-site before it reaches the western boundary. The southern erosional feature has an eroded channel with bed and banks that passes off the site onto the adjoining property to the west, and the western-most

March 2015 Private Horse Keeping and Grape Planting REC Consultants, Inc. 9 Biological Resources Letter Report

section has been concreted off-site, but the concrete ends and the channel completely fades before it intersects an existing paved driveway on the next parcel. The off-site investigation along the western property boundary confirmed that neither connects to any other water body or stream, and both are only non-jurisdictional erosional features.

OTHER UNIQUE FEATURES / RESOURCES

The Project site includes a hilltop and rock outcrops. A small ridgeline runs along the eastern side of the site, and this steeper portion of the site includes numerous small to medium rock outcrops. The hilltop topography is now dwarfed by the new the 11-story Palomar Medical Center that opened in 2012 on the slope just east of the site, after five years of construction (the long-term construction noise and presence of this large facility have likely contributed to degradation of habitat on the Project site).

Based on a review of aerial photography, the Project site has no connection to any wildlife corridors or linkages. The site appears to be more or less isolated in a setting that is now heavily developed for residential, light industrial, and industrial uses. State Route 78 and a railroad line are located 0.3 and 0.2 mile north of the site, respectively; Interstate 15 is located just over a mile to the east. Except for a “fringe” of residential land use next to the site, most land to the north, west, and east is developed commercially. To the south and southwest there are undeveloped field or yard areas, but beyond those areas the residential and light industrial development continues. There appears to be no possible wildlife corridor to any other open space that wouldn’t have to pass through the fenced yards of homes. This evaluation of the site’s isolation is supported by a previously issued but unused 2008 Habitat Loss Permit for the site (County of San Diego 2008), which states “The proposed project is surrounded by urban/developed lands and residential development…The project is not located within a wildlife corridor or linkage…Loss of the on-site habitat will not hinder the assembly of the preserve as it is not connected to any high-quality habitat.”

SIGNIFICANCE OF PROJECT IMPACTS AND PROPOSED MITIGATION

Impacts to biological resources can be categorized as direct, indirect, or cumulative. Direct impacts are a result of Project implementation, and generally include loss of vegetation, special- status habitats, and plant and animal populations; introduction of non-native species which may outcompete and displace native vegetation; activity-related wildlife mortality; loss of foraging, nesting, breeding, or burrowing habitat; and fragmentation of wildlife corridors. Indirect impacts occur as a result of the increase in human encroachment in the natural environment and include off-road vehicle use, which impacts special-status plant and animal species; harassment and/or collection of wildlife species; wildlife predation by domestic animals that intrude into open space areas; and increased wildlife mortality along roads.

Figure 5 depicts the direct impacts to biological resources that would occur from implementation of the Project. Direct and indirect Project impacts to habitats and special-status resources are discussed in the following sections.

Direct Impacts

March 2015 Private Horse Keeping and Grape Planting REC Consultants, Inc. 10 Biological Resources Letter Report

Implementation of the Project would result in impacts to 42.8 acres of land (the entire site), consisting of 20.1 acres of coastal sage scrub, 14.6 acres of non-native grassland, and 8.1 acres of developed and disturbed land. Habitat impacts resulting from implementation of the Project are summarized in Table 2.

Table 2. Habitat/Vegetation Communities and Impacts

Vegetation Community Existing Impacts Mitigation Mitigation Off-Site (acres) (acres) Ratio Required Mitigation (acres) (acres) Diegan coastal sage scrub 20.1 20.1 2:1 40.2 40.2 (County Habitat Code 32510) Non-native grassland 14.6 14.6 0.5:1 7.3 7.3 (County Habitat Code 42200) Disturbed land 7.6 7.6 - - - (County Habitat Code 11300) Developed land 0.5 0.5 - - - (County Habitat Code 12000) TOTAL 42.8 42.8 47.5 47.5

Impacts to 20.1 acres of coastal sage scrub and 14.6 acres of non-native grassland are significant and require mitigation.

The Project will also directly impact special-status wildlife species. A pair of California gnatcatchers and two coastal whiptails will be directly impacted through habitat loss, and two kestrels, a red-tailed hawk, and a turkey vulture will be directly impacted through loss of hunting/foraging land. Cooper’s hawk was not observed during REC’s surveys but was observed on-site in 2006 and has a high potential to occur on-site; therefore, loss of hunting/foraging land would be considered an impact to Cooper’s hawk as well. These impacts are significant and require mitigation. The impact to California gnatcatcher-occupied coastal sage scrub also requires a Habitat Loss Permit.

Because no special-status plant species were observed on-site or have high potential to occur on- site, the Project is not expected to result in significant direct impacts any special-status plants.

Common wildlife such as ground squirrels would be directly impacted by the Project; however, these impacts will be addressed through habitat mitigation and are not considered significant.

The Project will not result in significant impacts to any wildlife corridors, linkages, or wildlife nursery sites.

Indirect Impacts Because no special-status species have high potential to occur in the immediate Project area due to its location within a developed area, the Project is not expected to cause significant indirect impacts to any special-status plants or animals, or any wildlife corridors, linkages, or wildlife

March 2015 Private Horse Keeping and Grape Planting REC Consultants, Inc. 11 Biological Resources Letter Report

nursery sites.

Water quality and air quality in the Project area will be protected from significant indirect impacts by design features that would reduce environmental impacts, such as Best Management Practices that will be included in the Storm Water Pollution Prevention Plan.

Proposed Mitigation Because the Project will result in significant direct impacts to coastal sage scrub, non-native grassland, California gnatcatchers, coastal whiptails, kestrels, red-tailed hawk, turkey vulture, and Cooper’s hawk, mitigation will be required.

Mitigation for significant impacts to a pair of California gnatcatchers will consist of purchasing 40.2 acres of coastal sage scrub habitat/habitat credit in the Daley Ranch Conservation Bank.

Mitigation for significant impacts to two coastal whiptails, which are considered sensitive by the County of San Diego but not federal or State agencies, will be provided via habitat-based mitigation: the coastal sage scrub purchased for California gnatcatcher mitigation will also serve as coastal whiptail mitigation acreage.

Mitigation for significant impacts to turkey vulture, Cooper’s hawk, and other raptors including kestrel and red-tailed hawk, will be provided via habitat mitigation for non-native grassland; 7.3 acres of non-native grassland habitat or habitat credit will be purchased in Daley Ranch Conservation Bank.

Avoidance Measures

In addition to the mitigation measures and design features described above, the Project would incorporate these avoidance measures to prevent additional impacts:  All clearing and grubbing of vegetation and/or grading will occur outside the avian breeding season (February 15 to August 31, or sooner if a qualified biologist demonstrates to the satisfaction of the wildlife agencies that all nesting is complete).  If construction (other than vegetation clearing and grubbing) must occur during the breeding season, pre-construction surveys should be performed by a County-approved biologist within 10 calendar days prior to the start of construction to determine the presence of absence of nesting birds within 300 feet of the impact area. If nesting birds are detected, the County and Wildlife Agencies should be contacted to discuss the potential impact minimization measures to be implemented.  Project-related landscaping shall not include exotic plant species that may be invasive to native habitats. Invasive exotic plant species not to be used include those listed on the California Invasive Plant Council’s Invasive Plant Inventory.  In addition, landscaping adjacent to native habitat should not use plants that require intensive irrigation, fertilizers, or pesticides. Water runoff from landscaped areas should be directed away from adjacent habitat and contained and/or treated within the development footprint.  If the project is free of insect pests, particularly Argentine ants (Iridomyrmex humil) and fire ants (Solenopsis invicta), any planting stock to be brought onto the project site for

March 2015 Private Horse Keeping and Grape Planting REC Consultants, Inc. 12 Biological Resources Letter Report

landscaping should first be inspected by a qualified pest inspector to ensure it is free of pest species that could invade natural areas. Infested stock should not be allowed on the project site and should be quarantined, treated, or disposed of by qualified experts according to best management principles (i.e., in a manner that precludes invasion into natural habitats).

CUMULATIVE IMPACTS Cumulative impacts occur as a result of ongoing direct and indirect impacts from unrelated projects within a geographic area, and are assessed on a regional basis to determine the overall effect of numerous activities on a sensitive resource over a larger area. Impacts that may not be considered significant on a project-specific level can become significant when viewed in the context of other losses in the vicinity of the Project site. When evaluating cumulative impacts, CEQA states that “lead agencies should define the geographic scope of the area affected by the cumulative effect and provide a reasonable explanation for the geographic limitation used” (Sec. 15130(b)(3)). Cumulative projects that were evaluated in this analysis include those projects found within a geographic area of sufficient size to provide a reasonable basis for evaluating cumulative impacts. The geographic scope for this cumulative impact analysis includes past, present and future development projects (Tentative Tract Maps, Major Use Permits, etc.) within an approximate two (2) mile radius of the Project site.

In total, 54 cumulative projects were reviewed for this cumulative analysis, including projects located within the City of Escondido and the County of San Diego. Cumulative projects are identified in the Appendix F table and figure. The geographic scope of the analysis is based on the nature of the geography surrounding the Project site and the characteristics and properties of each resource and the region to which they apply. The analysis utilizes a conservative approach in order to capture the greatest number of projects that have the potential to create cumulatively considerable physical impacts when combined with this Project. The cumulative impact analysis focuses on reasonably searchable and foreseeable projects in the Project vicinity and also represents a reasonable and thorough analysis for the Project’s potential to create a cumulatively considerable physical impact on the environment.

Sensitive Habitats

Cumulative projects within the geographic scope of analysis have the potential to result in impacts to riparian habitat and other sensitive natural communities through direct loss of habitat from construction activities or the indirect loss of habitat from edge effects and habitat degradation. Cumulative projects may propose construction activities in undisturbed areas which would affect riparian or sensitive natural communities. Several of the cumulative projects listed in Appendix F would likely result in impacts to riparian habitat and sensitive natural communities. One such example is the Citracado Parkway Extension Project, which was determined to result in adverse impacts to sensitive natural communities such as southern willow riparian forest, southern willow scrub, coast live oak woodland and coastal sage scrub. Cumulative projects would be required to comply with applicable federal and/or state regulations, which provide protections for riparian and other sensitive habitats. In addition, many projects that affect riparian or other protected habitat types require approval from the USFWS and the CDFW. If potentially significant impacts would occur from particular cumulative

March 2015 Private Horse Keeping and Grape Planting REC Consultants, Inc. 13 Biological Resources Letter Report

projects, then mitigation measures would be implemented to reduce impacts to the extent feasible. However, without an adopted MSCP in place for the long-term protection of sensitive natural communities, a cumulative loss of riparian and other sensitive habitat would occur, even after mitigation has been implemented for individual projects. Therefore, a significant cumulative impact to riparian and other sensitive habitat, associated with the Citracado Parkway Extension Project and other cumulative projects, would occur. As discussed above, the Project would result in significant impacts to Diegan coastal sage scrub and non-native grassland habitat, and these impacts would contribute to a cumulative impact to sensitive natural communities. However, implementation of the mitigation identified above would ensure that this Project’s cumulative impacts are reduced to a level below significant. Therefore, the Project’s contribution, in combination with other cumulative projects, would not be cumulatively considerable.

Jurisdictional Wetlands and Waters

Cumulative projects within the geographic scope of analysis would have the potential to result in a cumulative impact associated with state and federally protected wetlands. For example, the Escondido Research and Technology Specific Plan resulted in impacts to jurisdictional wetlands. Cumulative projects would be required to comply with applicable state and federal regulations such as the Porter Cologne Water Quality Control Act and Sections 401 and 404 of the Clean Water Act. If potentially significant impacts would occur from particular cumulative projects, then mitigation measures would be implemented to reduce impacts to the extent feasible to meet the no-net-loss standard. Existing regulations would ensure that a significant cumulative impact associated with protected wetlands would not occur. As discussed above, the Project would not impact jurisdictional waters or wetlands. Therefore, the Project’s contribution, in combination with other cumulative projects, would not be cumulatively considerable.

Sensitive Species

Cumulative projects have the potential to impact sensitive species through clearing, grading, grubbing, trenching and other construction activities. Several of the cumulative projects listed in Appendix F would likely result in loss of habitat or edge effects that would significantly impact special-status plant and wildlife species. One such example is the Harmony Grove Specific Plan which would result in impacts to narrow endemic plant species. Cumulative projects would be required to comply with applicable federal and/or state regulations that provide protections for special-status plant and wildlife species, such as the Federal Endangered Species Act, the California Endangered Species Act and the California NCCP Act. In addition, some projects that affect special-status species require approval from the USFWS and the CDFW. If significant impacts occur from particular cumulative projects, then mitigation measures are usually implemented to reduce impacts to the extent feasible. However, without a comprehensive NCCP in place for the long-term protection of special-status plant and wildlife species for the entire southern California region, a cumulative loss of habitat supporting special-status plant and wildlife species would occur, even after mitigation has been implemented for individual projects. Further, past and present cumulative projects have caused the populations of some plant and wildlife species to drop below self-sustaining levels, which has resulted in their classification as candidate, sensitive or special-status. As indicated by their sensitive status, a significant

March 2015 Private Horse Keeping and Grape Planting REC Consultants, Inc. 14 Biological Resources Letter Report

cumulative impacts has already occurred to some of these species from past as present cumulative impacts. Therefore, a significant cumulative impact associated with special -status plant and wildlife species would occur. As discussed above, the Project would result in significant impacts related to sensitive animal species. These impacts would contribute to a cumulative impact to California gnatcatcher, coastal whiptail, kestrel, red-tailed hawk, turkey vulture, and Cooper’s hawk through loss of Diegan coastal sage scrub and non-native grassland habitat. However, implementation of the mitigation measures identified above would ensure that this Project’s contribution towards a cumulative impact is reduced to a level below significant. Therefore, the Project’s contribution, in combination with other cumulative projects, would not be cumulatively considerable.

This concludes REC’s biological letter report for the Private Horse Keeping and Grape Planting Project. Please do not hesitate to contact REC with any questions.

Re: Report on the Jet Ridge (APNs 228-400-13, 228-400-16, & 232-030-15) California Gnatcatcher Presence/Absence Surveys, Escondido, San Diego County, California.

Dear Mr. Wunderlin,

This report presents the results of three focused presence/absence surveys that I recently conducted for the federally threatened Coastal California Gnatcatcher Polioptila californica californica. The surveys were conducted within the above-referenced parcels totaling approximately 43 acres near the western boundary of the City of Escondido.

The California Gnatcatcher is a federal threatened species, a state species of concern, and is a "target species" of the NCCP process. This species is a non-migratory resident whose range covers the coastal plains and foothills of Southern California and northern Baja California. In San Diego County, it is widespread in coastal lowlands below about 2,000 feet elevation and typically occurs in or near Coastal Sage Scrub (CSS). The California Gnatcatcher population is seriously declining due to loss of habitat. Between 85% and 90% of this species’ habitat has been lost to urban or agricultural development. It is almost extirpated from Ventura, San Bernadino, and Los Angeles counties. The U.S. population is estimated to be just under 5000 pairs. San Diego County appears to be the center of abundance within the United States for this species.

The survey site is situated along the western boundary of the City of Escondido, in an area contiguous with County of San Diego jurisdiction and near the eastern boundary of the City of San Marcos (Figures 1 and 2). The approximate USGS coordinates for the site are 33°07’N, 117°07’W (San Marcos 7.5 minute series quadrangle, see Figure 3), as determined on-site by Global Positioning System (GPS) receiver. The property is bounded on the west by an area of existing industrial development, and on the east by the area under development for a power- producing facility and other industrial uses. Existing single-family residences border the site on the north and northeast. Land uses to the south include low-density residential, agricultural, or undisturbed native vegetation.

SITE CONDITIONS AND VEGETATION COMMUNITIES

Much of the central portion of the site was historically used as a quarry and gravel pit. Since abandonment of the gravel operation native plants typical of Diegan Coastal Sage Scrub have re-established. However, the habitat is low-quality at best, due to the relative low density of JET RIDGE GRADING PLAN L-14881 GNATCATCHER SURVEY REPORT

native plants, the original severe soil disturbance, and the high proportion of weedy non-native vegetation. Surrounding the historic gravel operation are areas of former avocado and citrus groves. Portions of these areas are currently dry-farmed to grow plant material to be baled and used for erosion-control purposes. At the present time, single-family homes are under construction on each of the three parcels. Permitted grading and clearing of pads, driveways, and cut and fill slopes has removed vegetation from these areas. Within the remaining undisturbed portions of the parcels are two areas of medium to high quality Diegan Coastal Sage Scrub (Figure 4).

METHODS

I surveyed the site three times in conformance with current USFWS protocol guidelines. The surveys were conducted under the authority granted to me by USFWS permit # TE-788036. The surveys were conducted by slowly walking routes within the project site (See Figure 4). After stopping, listening, and observing at intervals of approximately 30 meters, taped Coastal California Gnatcatcher vocalizations were played for 30 seconds. After the vocalizations were played, an additional two minutes were spent observing and listening before moving to the next observation site. Weather conditions and time of day were appropriate for the detection of Coastal California Gnatcatchers (Table 1).

RESULTS

A single California Gnatcatcher was detected on-site during the focused surveys (See Figure 4). Although the CSS on-site is relatively undisturbed, its fragmentation, relatively small size, and isolation from any nearby larger tracts of CSS (by dense industrial and residential development), limits the long-term viability of its values and functions as gnatcatcher habitat. Therefore, even though it is occupied at this time, this habitat on-site is considered medium- quality.

Thank you very much for the opportunity to conduct this work and prepare this report. Please contact me if you need any additional information or clarification.
