PSBS #K80 1 BIOLOGICAL ASSESSMENT OF THE PROPOSED BONITA HILLS ESTATES CITY OF CHULA VISTA, CALIFORNIA Pacific Southwest Biological Services, Inc, 4 September 1992 (Revised 16 March 1993) SUMMARY A biological survey of the 8.52-acre Michael Demish properry west and south of the Bonita Valley Reservoir revealed that the site is utilized by both Coastal Cactus Wrens and the California Gnatcatcher. The former inhabits sage scrub and cactus near the ravine along the western fenceline, and use areas extend off-site into higher quality habitat immediately west. The gnatcatchers were noted at the same locale; as well as in sage scrub now growing on the earthen seal for the reservoir (off-site). Two easements of 1.21 and 1.50 acres are proposed as dedicated biological open spaces to protect these sensitive birds and their habitat. Two plants of limited sensitivity were noted: Several California Adolphia grow near the ravine along the western boundary, and eight San Diego Viguiera occur further upslope to the north. Habitat quality varies widely on the properry, with disturbed grasslands in the south and north, and fair to good quality Diegan Sage Scrub covering much of the canyon's flanks in the center of the properry, INTRODUCTION A biological survey of the Demish site was performed by Pacific Southwest Biological Services, Inc. at the request of Ms. Marilyn Ponseggi. The purpose of the survey was to identify sensitive biological resources and constraints in the preliminary phases of development design for a fourteen lot split. METHODS The botanical portion of the survey was conducted by Craig H. Reiser on August 10, 1992. The on-foot survey covered all slope aspects, soil types, and drainages. Particular attention was given to the native sage scrub habitat, Vegetation and sensitive plant locations were delineated on a l' - 40' topographic map. An additional morning field date was utilized to flag boundaries for open space LotB. The zoological portion of the survey was conducted by Claude Edwards on August 6 from 1245 hours to 1600 hours, Skies were hazy, humidity was high; the temperature was 840 P.; and winds were light and from the west, 1~4{ffff 04/08/93 p4 Sai<thW<Jt BIDIo~ 5trVIas, Hll. PSBS #K80 2 All habitat types present within the study area were surveyed for wildlife, Binoculars of 10 x 40 power were used to observe and help in the identification of wildlife species and their habitats. Surface liner such as fallen logs, rocks and trash were overturned to locate amphibians and/or reptiles. Anention was also given to the identification of mammal tracks, scat or other sign, Listening for and noting wildlife vocalizations was also an important aspect of data gathering, Prior biological surveys of the immediate region were examined to assess sensitive resources known from the vicinity of the site (pSBS 1981, 1989; RECON 1982), Scientific nomenclature used in this report is from the following references: vegetation, Holland (1986); flora, Beauchamp (1986) and Munz (1974); birds, American Ornithologists' Union (1983, 1989); reptiles and amphibians, Collins (1990); and mammals, Jameson and Peeters (1988). Wildlife habitat delineations generally follow Mayer and Laudenslayer (1988). LOCATION The site lies within unsectioned lands of the Spanish grant for Rancho de la Naci6n; Township 17 South, Range 2 West of the San Bernardino Base and Meridian; USGS National City California 7.5' Quadrangle. Access is from the north via Moonview Drive (Figure 1). The 18.7 million gallon reinforced concrete Bonita Valley Reservoir to the east includes a two foot earthen "blanket" over the concrete, on which sage scrub was seeded (RECON 1982). The predominate land use surrounding the property is residential homesites; a large tract of sage scrub occurs on the eastern boundary (including the revegetated reservoir site). GENERAL PHYSIOGRAPHY The site consists primarily of a rectangular tract of land abutting the Bonita Valley Reservoir on the west, accessed by a continuation of Moonview Drive (presently gated at the property line), The southern end of the property features disturbed north-facing slopes which gradually drop into a drainage with sage scrub, The terrain rises again to the north onto a barren ridgeline, before dropping steeply into Bonita Valley. On the eastern boundary near the center of the site is a disturbed fill slope abuning the buried reservoir. The high elevation is 308 feet at the south end of the property, on a hillside below a water tank while the low elevation is approximately 116 feet in the extreme northwestern comer of the property on a steep slope overlooking Bonita Valley. Soils for the site are primarily Linne clay loam on 9-50% slopes, with Olivenhain cobbly loam 9-30% slopes near the southern boundary (Bowman 1973), Underlying geology is mapped as the Otay Formation; San Diego Formation, sandstone part; and Linda Vista Formation (Kennedy 1977). 1- 'f'!

PROJECT VICINITY MAP USGS 7.5' National City Quadrangle N . 1- .. 2000' I r So - rr PSBS #K80 4 BOTANICAL RESOURCES VEGETATION Two vegetation types were present on the property: Diegan Sage Scrub and a very disturbed Annual Grassland (Figure 2). DIEGAN SAGE SCRUB (2.89 acres; includes 0.15 acre Cactus Phase Diegan Sage Scrub) Shrub diversity at the Bonita Hills site is relatively limited. Unusual for the region is the high incidence of California Encelia (Encelia californica), which although a common plant, is rarely the dominant cover. Also occurring here is Coastal Sagebrush (Artemisia californica), Lemonadeberry (Rhus integrifolia) in the more mesic canyon bottom, Flat-top Buckwheat (Eriogonum fasciculatum), Spanish Bayonet (Yucca schidigera), and Black Sage (Salvia mellifera). Near the western boundary, by the drainage, grows some Jojoba (Simmondsia chinensis), Coast Cholla (Opuntia prolifera), and further upslope San Diego Viguiera (Viguiera laciniata) in limited numbers. The understory is relatively limited. Native elements include the late-flowering San Diego Wand Chicory (Stephanomeria diegensis), Bicolored Cudweed (Gnaphalium bicolor), Ocean Locoweed (Astragalus trichopodus), and California Filago (Filago californica). At one artificially moist locale along the southern boundary, near an irrigated residential yard, is found one Arroyo Willow (Salix lasiolepis) and a Great Marsh Evening Primrose (Oenothera elata); no other wetland species were seen on the property. In general, the higher quality, more diverse sage scrub is concentrated near the drainage along the western boundary. ANNUAL GRASSLAND/DISTURBED (5.63 acres) This disturbed habitat includes an abundance of the noxious Tecolote (Centaurea melitensis) and Wild Mustard (Brassica geniculata). Both of these weeds sometimes form such a dense, low canopy, that little else can grow beneath. On the south-facing slope is considerable Crystal lee Plant (Mesembryanthemum crystallinum), an introduced succulent species from South Africa. While some sage scrub elements are slowly pioneering within this dismrbed vegetation, the overall quality of this grassland is considered poor. Much of the grassland habitat in the south may have been created during construction of the adjacent buried reservoir. Grassy areas on the ridgeline in the north (near another old homesite) are likely the result of peripheral residential disturbance. c FLORA Seventy species of plants were recorded on-site of which thirty-seven are non-native invasive elements (Appendix 1). An estimated 20% of the flora consists of ephemeral native and non-native annuals which had decomposed by the August survey date. None of these additional species is expected to be listed as sensitive. /. .s/~'Y P""fic SoIdhwtsf BiologiCAl servfces, Inc. 04/08/93 o ex> :.: 'i; (/) II) (/) "- ~ , --~......... ~~. !

Reiser pers. obs.) prior to extensive grading over the last decade. Presence of Jojoba and dense concentrations of Coast Cholla (primarily immediately off-site to the west) are indicative of the desert influences seen in this region. ZOOLOGICAL RESOURCES GENERAL WILDLIFE HABITAT There are two major habitat-types for wildlife found over the site, Diegan Sage Scrub and Annual Grassland. A small canyon with a few large shrubs at the western end of the properry is kept moist by suburban runoff. This is an attractive area for animal-life in an otherwise arid environment. Two sensitive species of birds were observed utilizing the available sage scrub habitat, Coastal Cactus Wren (Campylorhynchus brunneicapillus sandiegense) and California Gnatcatcher (Polioptila californica). AMPHIBIANS Due to the timing and length of the survey, no species of amphibians were observed. Pacific Chorus Frog (Pseudacris regilla) and Western Toad (Bufo boreas) may occur in the artificially moist canyon area. REPTILES Only one species of reptile was observed due to humid, overcast weather conditions at the time of the survey. The Side-blotched Lizard (Uta stansburiana) is a common inhabitant of the sage scrub. Additionally, the following reptiles may also occur on the properry: Western Fence Lizard (Sceloporus occidentalis), Coastal Whiptail (Cnemidophorus tigris multiscutatus), Orangethroat Whiptail (Cnemidophorus hyperythrus) and San Diego Horned Lizard (Phrynosoma coronatum blainvillet). BIRDS Fifteen species of birds were observed on the site (Appendix 2). Most of the species were associated with the natural sage scrub habitat, including California Quail (Callipepla californica), Bewick's Wren (Tbryomanes bewicki.), Wrentit (Chamaea fasciata), California Thrasher (Toxostoma redivivum), California Towhee (Pipilo crissalis) and Rufous-sided Towhee (Pipilo erythrophthalmus). Anna's Hummingbirds (Calypte anna) fed in association with Tree Tobacco (Nicotiana glauca) growing on-site. Mourning Dove (Zenaida macroura), Northern Mockingbird (Mimus polyglottos) and House Finch (Carpodacus mexicanus) are associated with urban, exotic vegetation. As many as six Coastal Cactus W reDS were observed and heard during the field survey on-site and in an immediately adjacent area. These birds were seen and heard in the cholla and prickly pear cactus growing in the canyon along the western fenceline both on and just off-site. A separate single 1- S "3 -If 04/08/93 PAdftc &>IIthwcst JltDlogtCA' SlrViClS, Inc. PSBS #K80 7 Cactus Wren was heard singing from similar habitat in the canyon off-site and north of the gate on Moonview, and additiona! habitat is present on south-facing slopes within Diegan Sage Scrub to the east of this property. One pair of Ca!ifornia Gnatcatchers utilize this property, and adjacent, similar sage scrub habitat off-site. No nesting activity was detected, but the qua!ity of the available sage scrub habitat is rather good. A separate single gnatcatcher was seen and heard briefly to the northeast of this property along Randy Lane, indicating their presence there as well. Another pair of gnatcatchers uses the revegetated sage scrub covering the adjacent underground reservoir and the sma!l tract of sage scrub off-site in the southeast (south of Moonview Drive). MAMMALS Desert Cottontail (Sylvilagus auduboni/) was observed. Coyote (Canis latrans) was detected from its scat. Ca!ifornia Ground Squirrel (Spermophilus beecheyl) burrows were found, and they undoubtedly occur on-site, particularly within the disturbed terrain. SENSITIVE BIOLOGICAL RESOURCES SENSmVE VEGETATION SAGE SCRUB Both the Riversidian phase and the Diegan phase of Coasta! Sage Scrub have been severely reduced in tota! acreage over the last century. The principa! reasons for this reduction were initia!ly overgrazing by livestock and clearance of agricultura! lands, followed in many cases by urban residential and commercia! development. Some fauna! elements heavily dependent upon sage scrub habitat have suffered corresponding severe drops in individua! numbers and distribution. Notable examples include the Ca!ifornia Gnatcatcher, San Diego Cactus Wren, the coasta! race of the Sage Sparrow, and to a more limited extent, the San Diego Horned Lizard (which also occupies chaparra! habitats and open grasslands). Along with the extensive reduction in sage scrub has come a piecemeal fragmentation of larger tracts of such habitat. Isolation into small parcels devoid of viable linkages to other similar lands has undercut the value of such lands. The sensitivity of sage scrub in southern California will inevitably become more acute as additional lowland development takes place in San Diego, Orange and Riverside counties. SENSITIVE PLANTS DETECTED ON-SITE Two sensitive plant species occur on-site, California Adolphia and San Diego Viguiera. Severa! of the former grow near the western fence line near the area occupied by the Coasta! Cactus Wrens. Upslope, and of little botanica! significance, were seen eight San Diego Viguiera. This species is relatively common in the region, but has a limited U.S. range. 1- S ~-~ 04/08/93 Pllctftc southw,s( 11"'108100 5m>ias, I". PSBS IIK80 8 California Adolphia (Adolphia califorruca) LISTING: DISTRIBUTION: HABITAT: KNOWN SITES: 04/08/93 CNPS List 2 R-E-D Code 1-2-1 State/Fed. Status - None RHAMNACEAE Coastal San Diego County; Baja Califorrua, Mexico This short shrub is often intermixed with Diegan Sage Scrub, but occasionally occurs in peripheral chaparral habitats, particularly hillsides near creeks, The Califorrua Adolphia (sometimes called Califorrua Spinebush) is usually associated with Eriogonum fasciculatum and Artemisia californica in xeric locales where shrub canopy reaches four or five feet in height. During late summer and fall it may be virtually leafless, and therefore not apparent from a distance; however, its spiny stems are readily noted at close range. The San Miguel and Friant soils are both quite amenable to Califorrua Adolphia. Califorrua Adolphia is still found at a variety of coastal San Diego County locales. Substantial populations occur south of Del Dios Highway and 1 mile southwest of Lake Hodges Dam on steep north-facing slopes, and on south-facing slopes of Escondido Creek east of Lake Val Soreno. A very extensive colony with over 1000 shrubs was found in 1990 near the Inspiration Point Cross north of the Questhaven Retreat. One of the largest sites noted is a football field sized colony almost entirely composed of Adolphia upstream of the Sweetwater Reservoir, south of the old wooden bridge, on the south side of the river. Several thousand are found across the river and just upstream where they are a dominant element within the sage scrub. Scanered sites are in the hills south of the Sweetwater Reservoir and on the flanks of Mother Miguel Mountain. Another large population occurs on a west-facing slope east of Saxony Road near Batiquitos Lagoon. This shrub was noted in limited numbers at numerous other surveyed sites including the finger canyon east of Dillon Road on southern Otay Mesa, at scanered locales in Otay Valley east of the Interstate 805, in the sage scrub north of Lower Otay Lake, below Sweetwater Dam, a hillside west of Lake Murray Dam, along San Marcos Creek below San Marcos Dam, west of Melrose Drive and south of Shadowridge Drive in Vista, and on north-facing slopes of Peiiasquitos Canyon just south of the water treatment plant near Poway, Small populations were seen near Akita Lane in Rancho Santa Fe, at the eastern terminus of Rosemont Street in La Jolla, near the Fairbanks Country Club south of San Dieguito Road, south of Aliso Canyon Road near Rancho Santa Fe, on the Green Oaks Ranch at Agua Hedionda Creek, on canyon slopes west of Black Mountain Road and north of Peiiasquitos Canyon, on the eastern boundary of Fairbanks Ranch, near Mercy Road east of Interstate 15, and near the intersection of Poinsenia Avenue and Palomar Airport Road. Also, old reports on the periphery of its known range are near southern Camp Pendleton at Moro Hill, as well as to the southeast of most reports near Barrett Junction. Old Biological survey reports note sites, northwest of Lake Hodges Dam, near Lake Calavera, west of the Olivenhain Cemetery, on Rancho Aqua Hedionda Y Los Manos near Aqua Hedionda Creek, near El Apajo Road just south and beyond the Rancho San Dieguito boundary, 0.5 mile north of La Zanja Canyon and 1 mile east of San Dieguito Valley, southwest of Sienna Canyon Drive in Encirutas,. Sundance Mountain near Carmel Mountain Drive, between Evans Point and Lenerbox Canyon, and near the intersection of Fairrnont and Montezuma Roads in the viciruty of San Diego State Uruversity.

Collected south in Baja California to 300 6' North by Moran (SD 87216) at Sauzalito-2. Lightly collected in Baja with 14 specimens deposited in the San Diego Natural History Museum's herbarium. STATUS: California Adolphia is declining substantially due to urban growth; still healthy populations are extant. Rarely, this spiny shrub is a dominant on hillsides and such sites should be protected. Although Adolphia is not uncommon, a decade of continued urbanization along the coast will drastically reduce the populations now extant. California Adolphia should be considered for native revegetation projects in suitable habitat. I-~"-'f 04/08/93 PAC~' SOItthwtsf BlDloglC4! StrVIas, Inc. PSBS #K80 10 San Diego Viguiera (Viguiera /aciniata) LISTING: DISTRIBUTION: HABITAT: KNOWN SITES: CNPS List 2 R-E-D Code 1-2-1 State/Fed. Status - None ASTERACEAE San Diego County, Baja California, Mexico An arid Diegan Sage Scrub is typically the preferred habitat of this species, which is often a co-<lominant element of the shrub community where it occurs, along with Artemisia califomica. Generally the shrub cover is more open than at mesic, coastal locales where sage scrub is found. This species occurs on a variety of soil types. Olivenhain cobbly loam is mapped for the large populations of Viguiera at Lower Otay Lake and Sweetwater Lake; Las Posas fine sandy loam and Cieneba very rocky coarse sandy loam are utilized at some sites further inland such as near Sequan Indian Reservation. This is a dominant shrub in southern San Diego County in Diegan Sage Scrub habitat away from the immediate coast. It is very common in areas of the Jamul Mountains, and found by the thousands east of Upper Otay Lake and along the north shore of Lower Otay Lake. It is also abundant near Jamul Butte, Dehesa, Donohoe Mountain, at the south end of Dillon Road on Otay Mesa, in the hills east of Isham Springs and Jamacha Road, as well as near the Sequan Indian Reservation and Sloane Canyon. San Diego Viguiera is occasional northeast of Magnolia Avenue in Santee, in Murphy Canyon north of Clairemont Mesa Boulevard, at Tim Street in Bonita, by Lynndale Lane east of Interstate 805 in Chula Vista, around Lake Murray such as near Navajo Road, at Hidden Mountain Drive near EI Cajon, on the north-facing slopes overlooking the Otay River near Bayer Boulevard, at the terminus of Halifax Street in the Mission Gorge area, off Valley View Truck Trail in EI Cajon, near Serena Road in the Eucalyptus Hills area, by Farrell Lane in Crest, by Fuerte Valley Road in the Calavo Gardens area, near Ivanho Street on Dictionary Hill, off Vista de Chaparros Drive in Jamul, near Chester Grade Road in La Mesa, between Imperial A venue and 59th Street in Encanto, in Johnson Canyon on northeastern Otay Mesa, and in La Zanja Canyon near Rancho Santa Fe. It is rare north of Highway 78 and progressively more common as one travels south. It is found in open sage scrub in Military Sector Charlie on Camp Pendleton overlooking San Mateo Creek, its northernmost known locale. Old reports include east to Potrero, at Tecate, and near Barrett. Well inland it becomes uncommon north of Poway. Forty-two collections are found at the San Diego Natural History Museum's herbarium from Baja California; south to 280 6' North; where collected by Moran (SD 65229) approximately 5.5 miles southwest of Rancho el Canon. It is COmmon immediately south of San Diego County into Baja California. STATUS: San Diego Viguiera is declining but still found at numerous locales where occasionally it is a dominant shrub. This species shows some ability to colonize areas of mild disturbance and is readily grown from seed. This species is recommended for de-listing by the CNPS; it is too Common and wide-ranging in San Diego County to warrant such a listing. 04/08/93 I-57-If PAdjt' southw,st BloiDgtcal StTYfas, I.,. PSBS #K80 11 SENSITIVE PLANT SPECIES KNOWN FROM THE REGION Bur NOT FOUND ON-SITE Growing on a hillside approximately one half mile to the west of the study site in similar sage scrub habitat (pSBS 1989) are San Diego Barrel Cactus (Ferocactus viridescens) and Snake Cholla (Opuntia parryi var. serpentina), Both were searched for on-site but not seen. Also known from the area are Otay T arweed (Hemizonia conjugens) on clay substrate near Otay Lakes Road and along Proctor Valley Road to the east, Cleveland's Golden Stars (Muilla clevelandi!) a bulb not readily seen except during the spring, Green's Ground Cherry (Plrysalis greene!) which grows beneath sage scrub in Otay Valley, and San Diego Marsh Elder (Iva hayesiana) in drainages such as the Otay River. San Diego Thornmint (Acanthomintha ilicifolia) is found in Poggi Canyon in distinctive friable soils; Orcutt's Bird's Beak (Cordylanthus orcuttianus) and San Diego Bur-Sage (Ambrosia chenopodiifolia) once grew in Rice Canyon. SENSITIVE SPECIES OF VERTEBRATES OF VERIFIED OCCURRENCE Two species of sensitive vertebrates were detected on the subject property. Coastal Cactus Wren (Campylorlrynchus brunneicapi/lus sandiegense) LISTING: DISTRIBUTION: HABITAT: STATUS: USFWS (1991) - Category 2 CDFG (1990, 1991b) - Species of Special Concern Scattered populations occur from Piano T rabuco in southern Orange County, east to the Peninsular Ranges of San Diego County and south to Valle de las Palmas, Baja California. Patches of Prickly Pear or Cholla cactus in sage scrub. Declining. This subspecies is one of the most endangered birds in California. Large areas of its limited habitat has been lost and continues to decline due to urban development. Cactus wrens nest in the Coast Cholla in the drainage on-site and in similar habitat immediately west. As many as six birds were seen in this area of which 2 pairs are expected to make use of the site. Presence of cactus wrens on-site is considered extremely significant and warranting protection, California Gnatcatcher (Polioptila californica) LISTING: DISTRIBUTION: HABIT A T: STATUS: 04/08/93 USFWS (1986, 1989) - Category 2. A petition to list the California Gnatcatcher as Endangered was accepted in September 1991. A decision is due by spring of 1993. CDFG (1990, 1991b) - Species of Special Concern Everett (1979) - Declining San Diego County, Riverside County, and Orange County; Baja California, Mexico. Diegan and Riversidean Sage Scrub. Also occurs in Maritime Succulent Scrub. Seriously declining due to loss of habitat. BetWeen 85% and 90% of this species' habitat has been lost to urban or agricultural development. It has already been extirpated from Ventura, San Bernardino and most of Los Angeles counties. This bird is non-migratory. The United States population is currently estimated to be 1- .s 4K- If Plldftt southwest BiologiCAl 5<rViw, Inc. PSBS #K80 12 between 1,200 and 2,000 pairs (Atwood 1990). The California subspecies (P. c. cali/omicus) has a very narrow coastal range in Baja California, Mexico from the United States border south to the vicinity of EI Rosario. San Diego County appears to be the center of abundance within the United States for this species. This bird has been proposed for Endangered status by the U.S. Fish and Wildlife Service. One pair of gnatcatchers was observed in the reservoir lands to the east (off-site) which have been revegetated with Diegan Sage Scrub. The male was observed to cross the road into the sage scrub immediately off-site (and adjacent to disturbed grasslands on-site). A second pair was observed along _ __ __ ~he western boundary near the cactus wrens. SENSITIVE VERTEBRATES WHICH POSSIBLY OR PROBABLY OCCUR ON-SITE Six additional species of sensitive vertebrates are known from the region and may occur on-site. San Diego Homed Lizard (Phrynosorna coronaturn blainvillei) LiSTING: DISTRIBUTION: HABITAT: STATUS: USFWS (1991) - Category 2 CDFG (1990, 1991b) - Species of Special Concern CDFG (1991a) - Fully Protected SDHS (1980) - Endangered SDNGWS (1976) - Species of Local Concern Ashton (1976) - Threatened CITES (1976) - Category 2 IUCN (1979) - Depleted California and Baja California, Mexico Open chaparral, sage scrub, pinel oak woodlands, and along washes. Declining, primarily due to habitat destruction and habitat degradation. Pet collection has also attributed to their decline. This lizard is potentially present within the sage scrub. Its occurrence would be of limited biological import. Orangethroat Whiptail (Cmmidophorus hyperythrus belding') LiSTING: DISTRIBUTION: HABITAT: STATUS: 04/08/93 USFWS (1986, 1989, 1991) - Category 2 CDFG (1990, 1991b) - Species of Special Concern SDHS (1980) - Threatened SDNGWS (1976) - Species of Local Concern CITES (1976) - Category 2 IUCN (1979) - Rare Limited; found from southern Orange County, western Riverside and San Diego counties south to southern Baja California, Mexico. Open sage scrub, chaparral and along the edges of riparian zones and washes. This species is still relatively common in areas where good habitat occurs; however, vast areas of former habitat in the coastal lowlands have been converted to urban and agricultural development. /- s. '1-/f PAdftt SDlto,wtst BIDlcgilAl StrVItts, loc. PSBS #K80 13 This lizard is potentially present within the sage scrub and more likely than the horned lizard to occur on the properry. Its occurrence would be of limited biological import. Coastal Whiptail (Cnemidophorus tigris mu/tiscutatus) LISTING: DISTRIBUTION: HABITAT: STATUS: USFWS (1991) - Category 2 Santa Barbara County southward through the northern two-thirds of Baja California, Mexico. Open sage scrub, chaparral, open woodlands and bordering areas, along the edges of riparian zones and washes, desert and semi-arid habitats. This species is still relatively common in areas where good habitat occurs; however, vast areas of former habitat in the coastal lowlands have been converted to urban and agricultural development. This lizard is potentially present within the sage scrub; its occurrence on the site :""ould not be considered biologically significant. Northern Red Diamond Rattlesnake (Crotalus ruber ruber) LISTING: USFWS (1991) - Category 2 CDFG (1991b) - Species of Special Concern DISTRIBUTION: Within its United States range confined primarily to the Peninsular Ranges, being found from extreme southern Los Angeles County and Morongo Valley south into Baja California, Mexico. HABITAT: Frequents rocky outcrops in chaparral, sage scrub or desert scrub on both coastal and desert slopes, usually below 1219 meters. STATUS: Still fairly common where extensive areas of habitat remain. This and other species of rattlesnakes are frequently persecuted by humans. This species is considered sensitive because of its limited United States range. This snake is potentially present in the sage scrub. Occurrence on-site would be of limited biological importance. Northwestern San Diego Pocket Mouse (Perognathus fallax fallax) LISTING: DISTRIBUTION: HABITAT: STATUS: USFWS (1991) - Category 2 San Onofre north to Claremont, northeast to Banning, then south to J acumba and on into Baja California to San Quentin. Coastal sage scrub. Unknown, believed to be declining due to extensive habitat loss to development. This pocket mouse is locally common in the Bonita area in sage scrub and may occur on-site. Only a trapping program would likely indicate presence/absence. Occurrence on-site would be of no biological significance. I-lie-if 04/08/93 pll!lftt SOIIthwoJ( BIoIDgitAl Smiw, I.c. PSBS #K80 14 San Diego Desert Woodrat (Neatama lepida intermedia) HABITAT: STATUS: USFWS (1991) - Category 2 Coastal Southern California and Baja California from San Luis Obispo south to San Bernardino Mountains, Redlands, and continuing south through Julian and Dulzura and on into Baja California to the Sierra San Pedro M:hir. A disjunct population also is reported from the Porterville area. Sage scrub and chaparral. Unknown but believed to be declining due to loss of habitat. LISTING: DISTRIBUTION: This woodrat is locally common in the Bonita area in sage scrub and may occur on-site. Only a trapping program would likely indicate presence/absence. Occurrence on-site would be of no biological significance. EXPECTED BIOLOGICAL IMP ACTS Substantial redesign has eliminated initial significant biological impacts. Several adverse biological impacts will result from the proposed 12-lot split. 1. Loss of 1.5 acres of Diegan Sage Scrub. This habitat is severely declining in the Bonita region due to urban development, and its conservation is a focus of regional planning for both Chula Vista and San Diego Counry. This highest quality sage scrub is situated in proposed open space B (1.2 acres). Impact sage scrub is of lesser or degraded quality. 2. The loss of eight San Diego Viguiera are not considered biologically significant. RECOMMENDA nONS TO REDUCE BIOLOGICAL IMP ACTS Two dedicated biological open spaces are recommended which will include 1.2 acres of the higher quality Diegan Sage Scrub on-site in Area B, and protect habitat for both the Coastal Cactus Wren and the California Gnatcatcher (see Figure 2). The California Adolphia will also be protected within these areas. This western open space is 1.5 acres and is contiguous with high quality cactus wren and gnatcatcher habitat off-site to the west. It also links the revegetated lands of the reservoir with this sage scrub-dominated habitat (separated only by the existing paved road). A second easement (Lot A) covers a steep north-facing slope with grassland habitat. No clearance of vegetation or other forms of habitat and soil disturbance should occur within these dedicated areas with the exception of the sewage pipes and storm drainage pipe. As mitigation for the loss of fair to poor quality sage scrub (not within Open Space Log B), 0.3 acre of disturbed grassland in Lot B is recommended for revegetation and Diegan Sage Scrub. . A rtemisia cali/arnica, Encelia cali/arnica, Eriaganum fascicu/atum, Dip/acus puniceus, and Salvia melli/era should be the principal shrubby components of this revegetation. A three-year monitoring plan is /-/,/-/f' 04/08/93 PAJ:Iftt S/IfIIhwtJl BfuID,ptAI S<rvfas, Inc. PSBS #K80 15 further recommended to ensure the successful establishment of this scrub. The 0.3 acre constitutes the entire area within Area B mapped as grassland. Completion of this revegetation program will mitigate anticipated significant biological impacts from the project to a level of less than significant.
