A. Introduction and Site Description The project area is located south of La Costa Avenue, east of El Carnino Real. The project site is within Township 12 South, Range 4 West, Section 36 of the USGS 7.5' Encinitas quadrangle (Figure 2). It is not within the boundaries of any pre-approved mitigation areas It is not within or adjacent to any existing or proposed hardline conservation areas or proposed standards areas of the City's Habitat Management Plan (HMP, City of Carlsbad, 1999). The majority of the property is a flat area which appears to have been repeatedly disced and/or mowed for many years. The northern property boundary, adjacent to La Costa Avenue, is a moderately steep slope. Very steep slopes are on the southwestern, southern, and southeastern portions of the property. Elevations range from about 106 ft above mean sea level (amsl) at the lowest point in the northwestern corner of the property to about 205 ft amsl in the high point at the top of the slope in the southern portion of the site. Soils mapped by the US Soil Conservation Service are Altamont clay, 15-30% slopes, eroded, and Terrace escarpments (Bowman 1973). The property is vacant. Land adjacent to the south and west is developed, as is land across La costa Avenue to the north. The property immediately to the east is vacant, but additional residential development is just to the east of that parcel. B. Methods and Survey Limitations Prior to the initial survey, the California Department of Fish and Game's Natural Diversity Database (NDDB, version date March 1, 2002) was accessed to provide lists of all sensitive species that could potentially occur on the property. 1 m m • •AN CLCHINTC SAN ONOFftE VAUIT CENTEH OCEANSIDE CARtSBA ESCONDIOO WI7CM SAN FAMUAL C ICUCADI ENCINITA CARDIFF SOLANA BEACH PROJECT LOCATION ce CAJON B03TONIA •N093MONT 9PHIH9 VALLEY PACIFIC BfACH MISSION BEACH OCEAN BEACH SAN DIEGO CORONA DO MCITT SAN VSIOHO0 5 10 Scale in miles IMPERIAI BEACH Affinis REGIONAL LOCTION IN SAN DIEGO COUNTYShadow Valley Center 847 Jamacha Road EICajon.CA 92019 FIGURE 1 m m m m PROJECT LOCATION Affinis PROJECT LOCATION ON USGS 7.5' ENCINITAS QUADRANGLEShadow Valley Center 847 jamacha Road EICajon.CA 92019 FIGURE 2 The property was surveyed on May 22, 2002, between 10:00 am and 12:00 pm. The weather was clear, with a westerly breeze, and temperatures from the upper 60s to low 70s. The majority of the property was traversed, although binoculars were used to view vegetation on the steep southerly slopes. Habitats were mapped and all plant and animal species observed were recorded (Appendices 1 - 3). Nomenclature for plant species is according to Munz (1974), Beauchamp (1986), and Hickman (1993); and for animals is according to the National Geographic Society (1983), American Ornithologists Union (DeBenedictis, 1989), Jameson and Peeters (1988), and Stebbens (1985). Plant community classification is according to Holland (1986). C. Results 1. Vegetation. The biological resources of the site are mapped on Figure 3. Plant species observed are listed in Appendix 1. Four habitat types/vegetative associations were mapped on the property. Typical views of habitats are shown hi Figures 4-6. Disturbed/Ruderal (3.6 acres). The flat, previously disced and mowed area of the site was mapped as disturbed/ruderal. Furrow marks are evident across the site, and there are many patches of bare ground. In some areas there is a sparse growth of non-native grasses such as soft chess (Bromus mollis), ripgut grass (B. diandrus), and wild oat (Avena sp.). Occasionally, there are some very small sprouts of shrubs such as goldenbush (Isocoma menziesii) and coyote brush (Baccharis pilularis var. consanguinea), but overall the area is highly disturbed and weedy (Figure 4). Non-native grassland/landscaped (0.6 acre). The slope along the northern property boundary adjacent to La Costa Avenue supports a low growth of wild oats, pampas grass (Cortaderia jubata), and occasional ornamental trees including pines and Brazilian peppers (Figure 5). Landscaped (2.7 acres). The steep southerly slopes, which are below residential development to the south, are largely landscaped with trees and shrubs such as acacia, eucalyptus, Brazilian pepper, and myoporum. There are also occasional native shrubs such as chamise (Adenostoma fasciculatum), lemonade berry (Rhus integrifolid), and toyon (Heteromeles arbutifolia), but overall, the area is dominated by landscaping (Figure 6). Coastal sage scrub/mixed chaparral (1.1 acres). The steep southeastern slope supports a mix of coastal sage and chaparral species (Figure 6). Shrubs occurring in this area include black sage (Salvia mellifera), coast sage brush (Artemisia California*), toyon, lemonade berry, coyote brush, sawtooth goldenbush (Hazardia squarrosd), honeysuckle (Lonicera subspicata), and monkeyflower (Diplacus puniceus}. No plant species indicative of southern maritime chaparral were observed. -I . * m Affinis a Shadow Valley Center 847 jamacha Road ElCajon, CA 92019 DISTURBED/RUDERAL AREAS FIGURE 4 q i i i Affinis Shadow Valley Center 847 Jamacha Road ElCajon, CA 92019 NON-NATIVE GRASSLAND/ LANDSCAPED AREAS FIGURE 5 MIXED CHAPARRAL/COASTAL SAGE SCRUB LANDSCAPED AREAS Af finis Shadow Valley Center 847 Jamacha Road ElCajon, CA 92019 VEGETATION ON SLOPES FIGURE 6 2. Wildlife. Little wildlife was observed on the site. Only two species of birds were observed in the landscaped areas; these were California towhee (Pipilo crissalis) and house finch (Carpodacus mexicanus). Other common bird species would be expected to occur farther upslope in the mature trees. No raptor nests were noted in any of the trees. Two mammals were detected on-site. Mounds of Botta's pocket gopher (Thomomys bottae) were common in the disturbed/ruderal areas. Sign of Audubon's cottontail (Sylvilagus audubonii) was also noted in this area. No reptiles or amphibians were observed. Other animals such as small rodents may occur on-site, but these were not observed due to their nocturnal or secretive habits. • — - — . 3. Sensitive Habitat. No sensitive habitat occurs within the proposed development area (see Section E, below). The mixed chaparral/coastal sage scrub habitat would be considered sensitive. Under the draft City's HMP, habitats are ranked by sensitivity ("A" being the most sensitive and "F" being the least); coastal sage/chaparral mix is ranked at tier "D." 4. Rare and Endangered or Sensitive Species. No rare, endangered, or threatened plant species were observed on the site or are expected to occur. Sensitive plant and animal species reported by the NDDB from the general vicinity are listed in Appendices 2 and 3. While the coastal sage scrub/mixed chaparral habitat on-site is small, it is adjacent to additional habitat off-site to the east. Three protocol surveys were conducted to determine the presence or absence of the coastal California gnatcatcher (Polioptila calif ornica californica}, a federal-listed Threatened species. No gnatcatchers were observed on or adjacent to the property (Appendix 5). The property is within the geographic range (within two miles of the coast) of the federal- listed Endangered Pacific pocket mouse (PPM; Perognathus longimembris pacificus), a small rodent endemic to coastal Southern California. While the biology of this species is not well understood, PPM have been found on fine-grain, sandy substrates along the coastal strand, coastal dunes, river alluvium, and coastal sage scrub habitats on marine terraces; hi sparse to moderately dense coastal sage scrub or grassland vegetation on loose, sandy soils (Dodd, 2002). The potential for this species' occurrence on-site is considered low, given the lack of suitable soils, long-term disturbance of the site, and lack of suitable habitats. Additionally, there are no records of PPM from the Carlsbad area, and the species is not listed as a target species of concern hi the City's draft HMP. D. Evaluation of Resourcesc Native habitat is very limited on the project site. The coastal sage scrub/chaparral mix i ' contiguous with habitat to the east, but this off-site area is also relatively small and is sx / J 10 surrounded by development on three sides. Overall, the subject property does not support high- quality biological resources. E. Project Impacts and Recommended Mitigation Measures Project grading/encroachment would impact 5.2 acres of the property (Figures 7 and 8). Impacts would be 0;6 acre of non-native grassland/landscaping adjacent to La Costa Avenue, 0.5 acres of landscaped area at the base ofthTsoutnefljTslopeTand 4.1 acres of ruderal habitat. No significant direct unpactsjwould^ccur to biological resources, and thus nojnitigation measures would be required. • ~ No_grading is proposed in thejnixed_ghapaiTal/coastal sage scrub habitat, although the grading plan calls for construction of a retaining wall along die base of the slope supporting this habitat. The wall would vary in height from a minimum of six inches to a maximum of nine feet in height. V To avoid indirect impacts to biological resources, the following measure is recommended: • Prior to commencement of grading, the lower boundary of the mixed chaparral/coastal sage scrub habitat shall be staked and flagged by a qualified biologist at the base of the slope. The contractor shall be advised to avoid encroachment into this habitat during project grading and construction of the retaining wall.

No. 1716) Dear Christine, This letter is provided to summarize the results of three protocol surveys for the coastal California gnatcatcher (Polioptila californica californicd). Affinis surveyed a portion of an approximately 8-acre parcel on La Costa Avenue in the City of Carlsbad (Figures 1 and 2). The majority of the site is disturbed, but there is about one acre of mixed coastal sage scrub and chaparral habitat on a steep slope along the southeastern site boundary. This habitat is adjacent to additional off-site habitat, and thus it was concluded that there is some potential for the gnatcatcher to occur on-site. Three surveys were conducted as follows: DATE 7/02/02 7/09/02 7/16/02 TIME 09:30-10:15 10:00-10:30 09:00-09:30 WEATHER CONDITIONS Clear, upper 60s-lower 70s, light variable breeze Clear, 70s, breezy Clear, 70s, calm The survey route is shown on Figure 3. The area supporting the habitat is a steep slope. The base of the slope was walked, as well as a small dirt road running along the slope. Taped vocalizations were played to elicit responses. No California gnatcatchers were observed on or adjacent to the property during the three surveys. If you have any questions, please do not hesitate to call.
