Box 12727 Palm Desert, CA 92255 Re: Biological Survey of the Hadley Property, Zone 20, City of Carlsbad, California Dear Mr. Witt: A biological survey was conducted of the approximately 14-acre Hadley property situated within Zone 20 of the City of Carlsbad in the western portion of San Diego County, California (Figure 1). The property is located west of El Camino Real, south of Palomar Airport Road, east of Paseo del Norte and north of Aviara Parkway (Figure 2). The property is surrounded by agriculture and greenhouse production or open space to the north, west, and south and residential development to the east. Biological surveys of the property were conducted on 15 September 1998 by Dudek & Associates (DUDEK) to assess the existing conditions of the biological resources. The surveys augmented the existing data base accumulated through previous survey work (e.g., SANDAG 1994). The purpose of the visit was to identify the habitat types present, and identify constraints to development of the property. The project site is located within the City of Carlsbad, east of Black Rail Court, north of the Aviara development, south of the proposed La Costa Boulevard (extension of Camino de las Ondas), and west of El Camino Real. 1.0 METHODS AND SURVEY LIMITATIONS Data regarding biological resources present on the project site were obtained through a review of pertinent literature and through field reconnaissance. 1.1 LITERATURE REVIEW Biological resources present or potentially present on the Hadley property were identified through a from a variety of environmental studies and reports including the Multiple Habitat Conservation Program (SANDAG, 1997). General information regarding wildlife species present in the region was obtained from Unitt (1984) for birds, Bond (1977) for mammals, and Stebbins (1984) for reptiles and amphibians.

Hay worth, Ph.D. on 15 September 1998. All surveys were conducted by foot under favorable weather conditions, and all areas of the property were visited and inventoried for biotic components. The tune of the survey was between 0900 and 1130 for approximately 2.5 hours. Weather conditions were typically mild with temperatures ranging from 73 to 75 °F, windspeed from 1-3 MPH, and skies clear. 1.2.1 Resource Mapping Plant communities were mapped in the field onto an 100-scale (1" = 100') topography map of the site. Plant community classifications used in this report follow Holland (1986), with modifications to accommodate the lack of conformity of the observed communities to those of Holland. Locations of rare or sensitive plant and wildlife species also were mapped. 1.2.2 Flora All plant species encountered during the field surveys were identified and recorded. Species that could not be identified immediately in the field were brought back into the laboratory for further investigation. Latin and common names of plants used in this report follow the Jepson Manual (Hickman 1993). Where not listed in Hickman (1993), common names are taken from Beauchamp (1986). 1.2.3 Fauna Wildlife species detected during field surveys by sight, calls, tracks, scat, or other sign were recorded. Although daytime surveys result in the greatest number and highest diversity of wildlife sightings (because most birds are diurnal), many species of mammals are not observable during the day because of their nocturnal habits. In addition, many species of reptiles have extremely secretive habits, and hence, are difficult to detect as well. Binoculars (10 x 50 power) were used to aid in the identification of observed animals. Latin and common names used hi this report follow Stebbins (1985) for reptiles and amphibians, American Ornithologists' Union (1983, 1989) for birds, and Jones et al. (1992) for mammals. 1.2.4 Sensitive Biological Resources Sensitive biological resources are those defined as follows: (1) species that have been given special recognition by federal, state, or local conservation agencies and organizations due to limited, declining, or threatened population sizes and (2) habitat areas or plant communities that are unique, are of relatively limited distribution, or are of particular value to wildlife. Mr. Wes Witt 21 Sept. 1998 Re: Biological Survey for the Hadley Property Pg. 5 During the field work a special effort was made to survey more thoroughly those areas suspected to support sensitive resources. Most potentially occurring sensitive plants are perennials that can be detected at any tune of year if present in substantial numbers. 1.3 SURVEY LIMITATIONS Limitations of the surveys include a diurnal bias and seasonal constraints. For convenience and maximum visibility, surveys were conducted during the daytime hours. Although diurnal surveys maximize the number of observations of birds, which represent the largest component of the vertebrate fauna, they usually result in few observations of mammals, many of which are active primarily at night. No mammal trapping was conducted. Many species of reptiles and amphibians are secretive in their habitats and are rarely observed using normal survey techniques. No drift lines or pit fall traps were employed. 2.0 PHYSICAL CHARACTERISTICS 2.1 Site Description Land use within the Hadley property is currently open space/agriculture. The property is situated near the north central portion of the USGS 7.5 minute Encinitas quadrangle. The topography onsite consists of flat terrain in the western portion that slopes relatively steeply into a canyon in the eastern portion of the property Elevations range from approximately 360 feet above mean sea level (AMSL) to approximately 290 feet AMSL . 3.0 RESULTS 3.1 BOTANY - PLANT COMMUNITIES AND FLORAL DIVERSITY Based on species composition and general physiognomy, three plant communities (or habitat types) were identified within the Hadley property: southern mixed chaparral (with a small amount, less than 0.02 acre disturbed chaparral), southern coast live oak riparian forest, and disturbed or agriculture habitats. The existing plant communities are described below and their distribution onsite is presented on the 1" = 150' topographic site map (Figure 3). The acreage of each community was digitized and is indicated in the text and in Table 1. Mr. Wes Witt 21 Sept. 1998 Re: Biological Survey for the Hadley Property Pg. 7 TABLE 1 Existing Plant Community Acreages Plant Community (abbreviation used on map) Southern Mixed Chaparral (SMX) Coast Live Oak Riparian Forest (ORF) Disturbed or Agriculture Habitat (AGR or DH) TOTALS Existing Acreage 4.0 0.2 10.5 14.7 3.1.1 Southern Mixed Chaparral (4.0 acres) Southern mixed chaparral is a drought- and fire-adapted community of woody shrubs, 1.5-3.0 meters tall, frequently forming dense, impenetrable stands. It develops primarily on mesic north-facing slopes and in canyons, and is characterized by crown- or stump-sprouting species that regenerate following burns or other ecological catastrophes. This association is typically a mixture of chamise (Adenostomafasciculatum), mission manzanita (Xylococcus bicolof), ceanothus (Ceanothus sp.), Nuttall's scrub oak (Quercus dumosd), laurel sumac (Malosma laurind), and black sage. A relatively large area onsite is composed of southern mixed chaparral. It is located hi the eastern portion of the property and extends into the drainage that runs offsite to the northeast. Much of the area mapped as southern mixed chaparral onsite is dominated by chamise. There are also scattered individuals of mission manzanita, laurel sumac, chamise, black sage (Salvia mellifera), and California sagebrush (Artemisia californicd). A total of approximately 4.0 acres of southern mixed chaparral is present onsite. 3.1.2 Southern Coast Live Oak Riparian Forest (0.2 acre) Southern coast live oak riparian forest is an open to locally dense evergreen sclerophyllous riparian woodland dominated by coast live oak (Quercus agrifolid). According to Holland (1986) it is richer hi herbs and poorer in understory shrubs than other riparian communities. It typically occurs hi bottomlands and outer floodplains along larger streams, on fine grained, rich alluvium. Riparian habitats such as southern coast live oak riparian forest represent high quality wildlife habitat, providing structural diversity. They are important sites of primary Mr. Wes Witt 21 Sept. 1998 Re: Biological Survey for the Hadley Property Pg. 8 productivity and play a vital role in nutrient recycling and maintenance of water quality. Many species of animals that are resident in adjacent scrub habitat forage hi riparian areas during the drier tunes of the year. Onsite this community is represented by a band of coast live oak dominated habitat, a total of 0.2 acre with scattered individuals of southern mixed chaparral species. 3.1.3 Disturbed or Agriculture Habitat (10.5 acres) Disturbed or agriculture habitat is defined as areas where the native vegetation has been removed by mechanical means. The area may be unvegetated or vegetated with weedy non- native annual dicots, such as telegraphweed (Heterotheca grandiflord), Russian-thistle (Salsola tragus), and tocalote (Centaurea melitensis). This category includes open fields, areas devoid of vegetation, and other areas supporting weeds. Most of the disturbed/agriculture habitat onsite consists of the large area currently disced for agriculture production. A total of approximately 10.5 acres of disturbed or agriculture habitat is located onsite. 3.1.4 Floral Diversity A total of 42 species of vascular plants were recorded from the site (Appendix A). The relatively low floral diversity of the area is the result of its relatively small size and large patch of disturbed habitat located onsite. 3.2 ZOOLOGY - WILDLIFE DIVERSITY Eleven species of birds were observed during the surveys. The most commonly encountered residents in project area include California towhee (Pipilo crissalis), house finch (Carpodacus mexicanus) and scrub jay (Aphelocoma coerulescens). Most of the bird species observed onsite are fairly common in the region and are tolerant of occurring within an agricultural setting. One mammal species, California ground squirrel (Spermophilus beecheyi), was observed onsite. Two reptile species were observed onsite. 3.3 SENSITIVE BIOLOGICAL RESOURCES The following resources are discussed in this section: (1) plant and animal species present in the project vicinity that are given special recognition by federal, state, or local conservation agencies and organizations owing to declining, limited, or threatened populations, that are the results, in most cases, of habitat reduction; and (2) habitat areas that are unique, are of Mr. Wes Witt 21 Sept. 1998 Re: Biological Survey for the Hadley Property Pg. 9 relatively limited distribution, or are of particular value to wildlife. Sources used for determination of sensitive biological resources are as follows: wildlife — U.S. Fish and Wildlife Service (USFWS 1989, 1991), California Natural Diversity Data Base (CNDDB), California Department of Fish and Game (CDFG 1980, 1986), Remsen (1978), McGurty (1980); plants - USFWS (1990, 1993), CDFG (1987), CNDDB, and Skinner and Pavlik (1995); and habitats - CNDDB. 3.3.1 Sensitive Plant Species Two sensitive plant species, Nuttall's scrub (Quercus dumosd) and wart-stemmed ceanothus (Ceanothus verrucosus) were observed onsite. Both species were observed within the southern mixed chaparral area in the eastern and northern portions of the property. These species are described below and their distribution is shown on Figure 3. Ceanothus verrucosus - wart-stemmed ceanothus USFWS: former Category 2 candidate CDFG: None CNPS: List 2, 1-2-1 Wart-stemmed ceanothus is an erect, stiff-branched, rounded, evergreen shrub, 1.0-3.0 m tall, that occurs on dry hills and mesas hi coastal and mixed chaparral habitats below 300 m in western San Diego County and adjacent Baja California, Mexico. It is a spring-blooming species, flowering from January to April (Munz 1974). Beauchamp (1986) reports this species from Agua Hedionda, Encinitas, Leucadia, Torrey Pines State Reserve, Kearny Mesa, Lake Hodges, and Point Loma. Although moderately common chaparral along the coast, this species is the dominant shrub in some chaparral in the Lake Hodges/Mount Israel area. In Baja California, wart-stemmed ceanothus ranges from the Pacific coast to the foothills of the Sierra Juarez and Sierra San Pedro Martir (Wiggins 1980). A number of individuals of wart-stemmed ceanothus are present onsite. They are scattered throughout the southern mixed chaparral habitat and are in the eastern sloped portion of the property. Quercus dumosa - Nuttall's scrub oak USFWS: former Category 2 candidate CDFG: None CNPS: List IB, 2-3-2 In the Jepson Manual (Hickman 1993), the common, widespread species formerly known as scrub oak (Quercus dumosd) was treated as two closely related species ~ Nuttall's scrub oak (Quercus dumosd) and "ulterior" scrub oak (Quercus berberidifolid). Although interior scrub oak is widely distributed throughout southern California in chaparral habitats, Nuttall's scrub oak is restricted to the narrow coastal strip, and hence, has been severely affected by Mr. Wes Witt 21 Sept. 1998 Re: Biological Survey for the Hadley Property Pg. 10 development. Nuttall's scrub oak was one of eight native plants included in a "southern maritime chaparral listing package" circulated by the U.S. Fish and Wildlife Service in 1994. One individual of Nuttall's scrub oak was observed on the east-facing slope near the eastern property boundary of the site. It is likely that more individuals are present onsite. They would be located within the open space area of the proposed project, thus it was not deemed important that every individual be accounted for. 3.3.2 Sensitive Wildlife Species No sensitive wildlife species were observed or are likely to occur on the project site. 3.3.3 Sensitive Habitats Sensitive habitats are those that 1) are considered rare within the region, 2) support sensitive plant and/or wildlife species, or 3) function as corridors for wildlife movement. Sensitive habitats occurring onsite include the coast live oak riparian forest. Although southern mixed chaparral habitat is not considered sensitive by the resource agencies, because this patch of habitat contains two sensitive plant species, the habitat may be considered sensitive by the City of Carlsbad and/or the resource agencies. CORRIDORS Due to the location of the property within a residential development and agricultural area, little corridor potential exists. The habitat located at the eastern edge of the property connects to additional native habitat offsite to the east, however, the habitat ends at Aviara Parkway. The patch of coastal sage scrub is a small-sized patch connected to a medium- sized patch and although it varies in quality, still provides important coastal sage scrub resources for providing a possibly territory and possible stepping-stone movement corridor for sensitive species such as the California gnatcatcher. Unfortunately, the patch of habitat does not connect to additional habitat to form a corridor to aid in providing for dispersal of wildlife species in the area. Due to the location of the property in a developing portion of the City of Carlsbad, it is not possible for the property to play an important role as a wildlife corridor. The patch of native habitat located within the vicinity essentially runs into a dead end on this property. 5.0 ANTICIPATED PROJECT IMPACTS This section addresses potential impacts to biological resources that would result from implementation of the proposed project, and provides analyses of significance for each potential impact. Impacts were quantified by overlaying the limits of project grading on the Mr. Wes Witt 21 Sept. 1998 Re: Biological Survey for the Hadley Property Pg. 11 biological resources map of the site. For purposes of this assessment, all biological resources within the limits of grading for development are considered 100 percent lost. Impacts to biological resources can be direct - resulting from the permanent removal of habitat, or indirect - resulting from changes in land use adjacent to natural habitat (e.g., increased light, noise, and urban runoff, interruption of wildlife movement, etc.). Both of these types of impacts and their levels of significance are discussed in this section. 5.1 EXPLANATION OF DETERMINATION OF SIGNIFICANCE For this section, the following criteria are used to determine the significance of an impact: Substantial effect on a rare or endangered species plant or animal or habitat of that species is considered a significant impact. Substantial interference with the movement of any resident or migratory fish or wildlife species is considered a significant impact. Substantial reduction of habitat for fish, wildlife, or plants is considered a significant impact. 5.2 IMPACTS TO PLANT COMMUNITIES Direct Impacts Implementation of the proposed project would result in the direct loss of approximately 10.2 acres. This impact occurs only to the agriculture habitat and no impacts occur to the native habitat types or the disturbed habitat patches within the southern mixed chaparral habitat. Impact to the agriculture habitat is less than significant. The proposed plan results hi the preservation in open space of 4.5 acres (31 percent), 4.2 acres of which are native habitats. This includes preservation of 100 percent of coast live oak woodland and southern mixed chaparral. The location and configuration of the open space land is conducive to the long-term viability - it is a single, large, concentrated block of habitat linked with offsite natural habitat and provides a corridor between the Aviara development north to Palomar Airport Road and beyond via a stepping stone formation of preserved habitat. Mr. Wes Witt 21 Sept. 1998 Re: Biological Survey for the Hadley Property Pg. 12 Indirect Impacts Indirect impacts from the proposed development include the following: Reduction in carrying capacity of adjacent native habitats as a result of noise and lighting associated with development. Inadvertent potential increase of feral rat, cat, and other small predator populations in native habitats adjacent to proposed development areas. These impacts probably are most severe within the first 50 feet of development. Because the first 50 feet already is considered 100 percent impacted from the brush management zones, and indirect impacts from these sources are minimal beyond 50 feet, these impacts are consider less than significant. Nonetheless certain measures should be implemented to inhibit additional indirect impacts. These are discussed below under mitigation. 5.3 IMPACTS TO SENSITIVE PLANTS Direct Impacts Implementation of the proposed project would result in no loss the sensitive plant species occurring onsite. Indirect Impacts Indirect impacts may result in the intrusion of non-native plant species within the first 50 feet of the proposed development. However, due to the density of the habitat and high percent cover by native plant species, this intrusion will probably be negligible. These indirect impacts are considered less than significant. 5.4 IMPACTS TO SENSITIVE ANIMALS Direct Impacts No impacts would occur to sensitive animal species - no sensitive animal species were found onsite or are likely to occur. Indirect Impacts Indirect impacts may result in the reduction of the carrying capacity of the native habitats, however, the patch of habitat onsite is connected to additional habitat offsite. These indirect impacts are considered less than significant. Mr. Wes Witt 21 Sept. 1998 Re: Biological Survey for the Hadley Property Pg. 13 6.0 RECOMMENDED MITIGATION MEASURES No impact occurs to sensitive habitats, species, or habitat features, thus no mitigation is required for the proposed development project for the Hadley property.
