Cummins SWCA Environmental Consultants 625 Fair Oaks Boulevard, Suite 190 South Pasadena, California 91030 (626) 240-0587 February 3, 2009 SWCA Project Number: 15220 • • BIOLOGICAL RESOURCES ASSESSMENT TURPANJIAN PROPERTY EXECUTIVE SUMMARY Introduction: SWCA Environmental Consultants was retained by Mr. Gerald Turpanjian to conduct a biological resources assessment in support of a grading permit for the proposed construction of a residential home (project) located at 0 Pine Tree Lane in the city of Rolling Hills, Los Angeles County, California. The purpose of this assessment is to determine whether the proposed project has the potential to affect sensitive biological resources, and to explore options for mitigating those resources that will comply with the goals and objectives of the City. The project is located on a parcel approximately 4.05 acres in size; project grading is proposed for 1.8 acres of the parcel. Methods and Results: SWCA biologist Taya Cummins conducted the field visit on January 28, 2008, between 7:00 a.m. and 8:30 a.m., implementing standard biological investigation field methodologies. Vegetation within the project area consists primarily of Venturan coastal scrub, nonnative grassland, and urban lands. Because all of the habitats as well as plants and wildlife species identified in the California Natural Diversity Database (CNDDB) and California Native Plant Society (CNPS) Rare Plant Inventory searches were determined to be "absent," no special -status species are expected to occur within the project area. In addition, no oak trees were identified within the project area. No wetlands or other waters were identified within the project area. Project implementation would result in the removal of approximately 1.8 acres of nonnative grassland. This habitat is not considered sensitive. The project area likely provides nesting habitat for nesting avian species whose nests and young are protected under the Migratory Bird Treaty Act (MBTA) and California Fish and Game Codes. Construction activities that occur from January 15 through September 15 could result in both direct and indirect impacts to nesting avian species. Any impacts (direct or indirect) that result in the abandonment or destruction of an active nest or the destruction of eggs or young of any protected avian species, including special -status species, would be considered a significant impact under the California Environmental Quality Act (CEQA). Recommendations: SWCA recommends that ground -disturbing and vegetation -removal activities associated with construction of the project be performed outside of the breeding season for birds, or between September 16 and January 14. If these project activities cannot be implemented during this time period, biological surveys and nest protection measures will be necessary. In addition, SWCA recommends that a landscape plan, as required by the City, include the use of native drought -tolerant vegetation and conform to the County's fuel modification guidelines.

INTRODUCTION 1.1 PURPOSE OF ASSESSMENT SWCA Environmental Consultants was retained by Mr. Gerald Turpanjian to conduct a biological resources assessment in support of a grading permit for the proposed construction of a residential home (project) in the city of Rolling Hills, Los Angeles County, California. The project is located on a parcel approximately 4.5 acres in size; project grading is proposed for 1.8 acres of the parcel. The purpose of this assessment is to determine whether the proposed project has the potential to affect sensitive biological resources, and to explore options for mitigating those resources that will comply with the goals and objectives of the City. This biological resources assessment did not include a formal wetland delineation or focused surveys and is not intended to provide sufficient documentation for federal or state permits. 1.2 PROJECT LOCATION AND DESCRIPTION The project is located at 0 Pine Tree Drive in the city of Rolling Hills, Los Angeles County, California. The project area is located approximately 0.8 mile southwest of the entrance to the gated community of Rolling Hills at the intersection of Palos Verdes Drive North and Portuguese Bend Road/Rolling Hills Road, and 3.8 miles west of the Interstate 110 freeway. The project area, which is situated at an elevation of approximately 300 meters (984 feet) above mean sea level, is located in the San Bernardino Meridian, Township 5 South, Range 14 West, Section 4 of the 1964 U.S. Geologic Survey (USGS) Torrance 7.5- minute topographic quadrangle, photorevised 1981 (Figure 1). 1.3 REGULATORY SETTING 1.3.1 Federal Regulations Section 404 of the Clean Water Act (33 Unites States Code [USC] 1344 et seq.) Section 404 of the Clean Water Act (33 USC 1344 et seq.) prohibits discharge of dredged or fill material into "waters of the United States" without a permit from the U.S. Army Corps of Engineers (USACE). The USACE and the U.S. Environmental Protection Agency administer this Act. In addition to traditional navigable waters, the definition of waters of the U.S. includes wetland areas in or adjacent to jurisdictional waters "that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions" (33 Code of Federal Regulations [CFR] 328.3 7b). Projects with impacts to waters of the U.S. may require an individual permit. Small-scale projects with minimal impacts may be authorized by nationwide permits, which have an expedited process compared with the individual permit process. Mitigation of wetland impacts is required as a condition of the Section 404 permit and may include preservation, restoration, or enhancement within the study area and/or off - site restoration or enhancement. The characteristics of restored or enhanced wetlands must be equal to or better than those characteristics of affected wetlands to achieve no net loss of wetlands values.

Federal Endangered Species Act (ESA; 16 USC 153 et seq.) Applicants for projects that could result in adverse impacts to any federally listed species are required to mitigate potential impacts in consultation with the U.S. Fish and Wildlife Service (USFWS). Adverse impacts, defined as "take," are prohibited except under authorization through Section 7 or Section 10 consultation, and Incidental Take Authorization. During consultations, determinations are made regarding the proposed project and its potential to jeopardize the continued existence of federally listed species, and reasonable and prudent mitigation measures required to avoid such jeopardy. Mitigation is required for adverse impacts to any listed species or candidate species proposed for listing. Take, under federal definition, currently includes actions that could result in "significant habitat modification or degradation" (50 CFR Section 17.3). Candidate species are not protected under ESA. However, the USFWS advises project applicants that candidate species could be elevated to listed status at any time, and should be regarded as species with special consideration. Migratory Bird Treaty Act (MBTA; 16 USC 703 to 711) The MBTA prevents the take of all migratory birds, including their nests and eggs. Bald and Golden Eagle Protection Act (16 USC 668) This act specifically protects bald and golden eagles from being killed or their eggs taken. 1.3.2 State Regulations California Endangered Species Act (CESA; Fish and Game Code Section 2050 et seq.) Species listed under the CESA cannot be taken or harmed, except under specific permit. As currently stated in the act, "take" means to hunt, pursue, catch, capture, or kill or to attempt to do so. Fish and Game Code Sections 3511, 4700, 5050, and 5515 These sections provide a provision for the protection of bird, mammal, reptile, amphibian, and fish species that are "fully protected." Fully protected animals may not be harmed, taken, or possessed. Fish and Game Code Section 3503 This section states that it is unlawful to take, possess, or needlessly destroy the nest or eggs of any bird, except as otherwise provided by this Code or any regulation made pursuant thereto. Fish and Game Code Section 3503.5 This section provides protection for all birds of prey, including their eggs and nests. SWCA Environmental Consultants BIOLOGICAL RESOURCES ASSESSMENT TURPANJIAN PROPERTY Fish and Game Code Section 3513 This section makes it unlawful to take or possess any migratory non -game bird as designated in the MBTA. Fish and Game Code Sections 1900 et seq., or Native Plant Protection Act This section lists threatened, endangered, and rare plants so designated by the California Fish and Game Commission. Title 14, California Code of Regulations, Sections 670.2 and 670.5 These sections list animals designated as threatened or endangered in California. The California Department of Fish and Game (CDFG) designates species considered to be indicators of regional habitat changes, or candidate species for future state listing, as California Species of Special Concern. Species of Special Concern do riot have special legal status, but are used by the CDFG as a management tool when considering the future use of any land parcel. California Fish and Game Code (Sections 1601 through 1607) These sections prohibit alteration of any lake or streambed, including intermittent and seasonal channels and many artificial channels, without execution of a Streambed Alteration Agreement through the CDFG. This applies to any channel modifications that would be required to meet drainage, transportation, or flood control objectives of the project. California Environmental Quality Act (CEQA) CEQA requires that a project's effects on environmental resources must be analyzed and assessed using criteria determined by the lead agency. CEQA defines a rare species in a broader sense than the definitions of threatened, endangered, or California Species of Concern. Under this definition, CDFG can request additional consideration of species not otherwise protected. 1.3.3 Local Regulations City of Rolling Hills The City of Rolling Hills Planning Department oversees all development permits. As part of this process, they ensure that projects are developed in an environmentally responsible manner. The City's Planning Department seeks to respect native wildlife and natural surroundings by protecting natural resources through project -specific recommendations. 1.4 ENVIRONMENTAL SETTING The project area is situated primarily on a hilltop and an adjoining hillside that slopes to a horse trail to the north, Pine Tree Lane to the east, an adjacent residential property to the south, and Upper Blackwater Canyon Road to the west. Vegetation within the project area and the adjacent parcels is highly disturbed and consists primarily of nonnative grassland with a few coastal sage scrub community shrubs scattered along the project boundary. No drainages are present within or adjacent to the parcel. Soils throughout the SWCA Environmental Consultants 7 • • BIOLOGICAL RESOURCES ASSESSMENT TURPANJIAN PROPERTY project area have been highly disturbed. Land uses in the vicinity of the project area include large residential lots, equestrian facilities, ruderal fields, and orchards, pastures, and urban development. The Pacific Ocean is located 4 miles south of the project area. 2. METHODS 2.1 LITERATURE AND DATABASE SEARCH SWCA biologists reviewed existing sources of information regarding occurrences of special -status species and assessed the potential for occurrence of these species within the project area. Special -status species are plants and animals in one or more of the following categories: • Species listed or proposed for listing as threatened or endangered under the federal ESA (50 CFR 17.12 [listed plants], 50 CFR 17.11 [listed animals], and various notices in the Federal Register [FR] [proposed species]). • Species that are candidates for possible future listing as threatened or endangered under ESA (67 FR 40657, June 13, 2002). • Species listed or proposed for listing by the State of California as threatened or endangered under CESA (14 California Code of Regulations [CCR] 670.5). • Species that meet the definitions of rare or endangered under CEQA (State CEQA Guidelines Section 15380). • Plants listed as rare under the California Native Plant Protection Act (California Fish and Game Code Section 1900 et seq.). • Plants considered by the CNPS to be "rare, threatened, or endangered in California" (Lists 1B and 2 in CNPS 2009). Plants listed by CNPS as plants about which more information is needed to determine their status and plants of limited distribution (Lists 3 and 4 in CNPS 2001), which may be included as special -status species on the basis of local significance or recent biological information. Animal species of special -concern as listed by CDFG (2008). Animals fully protected in California (California Fish and Game Code Sections 3511 [birds], 4700 [mammals], 5050 [amphibians and reptiles], and 5515 [fish]). Animals included on the California Special Animals List (CDFG 2008) because of inclusion on one or more of several "watch lists," including the International Union for Conservation of Nature (IUCN) Red List, the American Bird Conservancy (ABC) Green List, the Audubon WatchList, the Bureau of Land Management Sensitive Species list, the California Department of Forestry and Fire Protection Sensitive Species list, the U.S. Department of Agriculture (USDA) Forest Service Sensitive Species list, the USFWS Birds of Conservation Concern list, the United States Bird Conservation (USBC) Watch List, bat species included on the Western Bat Working Group's (WBWG) Regional Priority Matrix as High or Medium, and the Xerces Society Red list of pollinators. The following sources of information were consulted: • The California Natural Diversity Database (CNDDB) (CNDDB 2009) for the USGS Torrance 7.5-minute quadrangle and eight surrounding quadrangles in the project vicinity, including Venice, Inglewood, South Gate, Redondo Beach, Long Beach, Redondo Beach OE S, San Pedro, and Long Beach OE S; accessed January 28, 2009.

Special attention was given to the proposed project grading limits plus a 50- foot buffer around this area to determine whether sensitive habitats or special -status species occur there. Photographs were taken to document biological resources and field conditions. Specific survey methods are described in detail below. All plant species observed during the survey, including special -status species, were identified to species or further using taxonomic nomenclature provided in The Jepson Manual of Higher Plants of California (Hickman 1993). Vegetation communities observed during the survey were described in field notes, verified on aerial photographs, and described according to A Manual of California Vegetation (Sawyer and Keeler -Wolf 1995) and Preliminary Descriptions of the Terrestrial Natural Communities of California (Holland 1986) whenever appropriate. Any potential wetland areas were also described and noted on aerials, but not formally delineated. Wildlife species were recorded during the survey of the project area and were detected by sight and sound. Wildlife habitats were also assessed within the project area. Special attention was given to the potential for nesting bird species, including raptors, that could nest in trees within and adjacent to the project area. All species were identified to the lowest possible taxonomic level. No nocturnal or protocol surveys were conducted. 2.3 ASSESSMENT OF SPECIAL -STATUS SPECIES POTENTIAL Following the database searches and field survey, SWCA assessed the potential for occurrence for special -status species within the project area and its immediate vicinity. This consisted of assessing the biological conditions within the project area and its immediate vicinity and the known occurrences of special -status species within the general vicinity of the project area (nine -quadrangle area). During the assessment, each species was assigned to one of the categories listed below. Present: Species is known to occur within the study area, based on recent (within 20 years) CNDDB or other records, and/or was observed within the study area during the field survey(s). May occur: Species is known to occur in the vicinity of the study area (based on recent [within 20 years] CNDDB or other records within 5 miles [10 miles for butterfly, bird, and bat species] and/or based on professional expertise specific to the study area or species), and there is suitable habitat within the study area. Alternatively, there is suitable habitat within the study area and the study area limits are within the known range' of the species. For avian species, a distinction was made between occurrence potential on the study area as a forager, nester, and/or transient. SWCA Environmental Consultants BIOLOGICAL RESOURCES ASSESSMENT TURPANJIAN PROPERTY Not likely to occur: Species is known to occur in the vicinity of the study area (within 5 miles for plants and terrestrial animals or 10 miles for butterfly, bird, and bat species); however, there is poor quality or marginal habitat in the study area. If the species occurs at the study area, it would likely be as a migrant, and the species is not likely to reproduce (breed or nest) within the study area due to a lack of suitable habitat or because the study area is outside of their known breeding range. Absent: There is no suitable habitat for the species within the study area, or the study area is located outside of the known range of the species. Alternatively, a species was surveyed for during the appropriate season with negative results for species occurrence. 3. RESULTS 3.1 FIELD SURVEY SWCA biologist Taya Cummins conducted the field visit on January 28, 2009, between 7:00 a.m. and 8:30 a.m. Conditions encountered during the survey included average temperatures of 58 degrees Fahrenheit and a slight breeze. 3.2 BIOTIC HABITATS Habitats identified within the project area are mapped in Figure 2 and described in detail below. Acreages of biotic habitats within the project area are provided in Table 1, including graded areas and total acreages.

This habitat was identified on an abandoned orchard site within the grading limits and the surrounding 50-foot buffer of the adjacent parcels (Photograph 1). Plant species identified in this habitat included brome grasses (Bromus spp.), black mustard (Brassica nigra), prickly lettuce (Lactuca seriola), Bermuda buttercup (Oxalis pes-capre), sweet fennel (Foeniculum vulgare), and redstem filaree (Erodium cicutarium). In addition, two mature pepper trees (Schinus molle) were identified at the entrance to the project area along Pine Tree Lane, and a mature pine tree (Pinus sp.) was located along the western project boundary. This habitat dominates the project area, encompassing 3.727 acres (Table 1; Figure 2). In addition, the grading area includes 1.80 acres of this habitat, which will be directly affected by the project. This habitat is not considered sensitive.

Vegetation within the horse trail easement is consistent with species identified in the nonnative grassland habitat. Within the project area, the horse trail consists of 0.183 acre and will not be affected by grading associated with this project (Table 1; Figure 2). This habitat is not considered sensitive. Photograph 3. Horse Trail (center) and toyon shrub. Urban or Built-up Urban or built-up lands are characterized by areas of intensive use, with much of the land covered by structures or associated facilities (Anderson et al. 1976). Included in this category are cities, transportation, power, and communications facilities. Within the project area, these lands include paved roads that fall within the parcel boundary. The habitat value of these lands is generally poor due to the high levels of activity on the sites and the lack of substantial vegetative cover. Approximately 0.115 acre of urban or built-up land occurs within the project area along Pine Tree Lane and Upper Blackwater Canyon Road (Photograph 4).

Urban or built-up land (Upper Black Canyon Road). 3.3 ASSESSMENT OF SENSITIVE BIOLOGICAL RESOURCES A list of special -status species known to occur within the vicinity of the study area was generated from the CNDDB and the CNPS 2009 online Inventory of Rare and Endangered Plants of California. A total of 60 special -status species, including 25 plants and 35 wildlife species as well as three sensitive habitats, were identified within the nine -quadrangle area in the vicinity of the project area (Appendix B; Figure 3). Provided below are expanded descriptions for those species or habitats that were either present within the project area, or their occurrence potential was evaluated as "may occur" within the project area. 3.3.1 Sensitive Habitats During the field survey, the potential for sensitive and potentially jurisdictional habitats was assessed within the project area. A search of the CNDDB records for sensitive habitats was also conducted, which identified three sensitive habitats within the nine -quadrangle area, including southern coastal bluff scrub, southern coastal salt marsh, and southern dune scrub. None of these habitats were identified within the project area during the survey. 3.3.2 Special -status Species Special -status Plants During the field survey, habitats capable of supporting special -status plant species were evaluated within the project area. Based on the analysis provided in Appendix B, the following species were eliminated from further consideration because (1) there is no suitable habitat within the project area and there are no local records (within 5 miles) in the vicinity of the project area and/or (2) the project area is outside of their known range. Alternatively, although there' are records of these species within the project's vicinity (within 5 miles), there is no suitable habitat within the project area to support the occurrence of these species. These species were assessed as "absent:" SWCA Environmental Consultants 14 BIOLOGICAL RESOURCES ASSESSMENT TURPANJIAN PROPERTY • Aphanisma (Aphanisma blitoides) • Ventura Marsh milk -vetch (Astragalus pycnostachyus var. lanosissimus) • Coastal Dunes milk -vetch (Astragalus tener var. titi) • South Coast saltscale (Atriplex pacifica) • Parish's brittlescale (Atriplex parishii) • Davidson's saltscale (Atriplex serenana var. davidsonii) • Lewis' evening -primrose (Camissonia lewisii ) • Southern tarplant (Centromadia (=Hemizonia) parryi ssp. australis • Orcutt's pincushion (Chaenactis glabriuscula var. orcuttiana) • San Fernando Valley spineflower (Chorizanthe parryi var. fernandina • Salt marsh bird's -beak (Cordylanthus maritimus ssp. maritimus) • Catalina crossosoma (Crossosoma californicum) • Beach spectaclepod (Dithyrea maritime) • Island green dudleya (Dudleya virens ssp. insularis) • Vernal barley (Hordeum intercedens) • Coulter's goldfields (Lasthenia glabrata ssp. coulteri) • Santa Catalina Island desert thorn (Lycium brevipes var. hassei) • Spreading navarretia (Navarretia fossalis ) • Coast woolly -heads (Nemacaulis denudata var. denudate) California orcutt grass (Orcuttia californica ) Lyon's pentachaeta (Pentachaeta lyonii) Brand's star phacelia (Phacelia stellaris) Ballona cinquefoil (Potentilla multijuga) Estuary seablite (Suaeda esteroa) San Bernardino aster (Symphyotrichum defoliatum) Because all of the plants identified in the CNDDB and CNPS Rare Plant Inventory searches were determined to be "absent," no special -status plant species are expected to occur within the project area. In addition, no oak trees were identified within the project area. Special -status Wildlife During the field survey, habitats capable of supporting special -status wildlife species were evaluated within the project area. Based on the analysis provided in Appendix B, the following species were eliminated from further consideration because (1) there is no suitable habitat within the project area AND there are no local records (within 5 miles or 10 miles for butterfly, bird, and bat species) in the vicinity of the project area, and/or (2) the project area is outside of their known range. Alternatively, although there are records of these species within the project's vicinity (within 5 miles or 10 miles for butterfly, bird, and bat species), there is no suitable habitat within the project area to support the occurrence of these species.

IMPACT ANALYSIS 4.1 BIOTIC HABITATS Project implementation would result in the removal of approximately 1.80 acres of nonnative grassland. This habitat is not considered sensitive but may provide suitable nesting or foraging habitat for a variety of birds. 4.2 SENSITIVE HABITATS No sensitive habitats listed by CNDDB were identified within the project area. Also, no wetlands or other waters of the U. S. were identified within the project area. 4.3 SPECIAL -STATUS PLANTS No special -status plant species listed by CNPS or CNDDB were determined to occur within the project area. Therefore, no impacts to special -status plant species are expected as the result of implementation of the proposed project. 4.4 SPECIAL -STATUS WILDLIFE No special -status wildlife species listed by CNDDB were determined to occur within the project area. Therefore, no impacts to special -status wildlife species are expected as the result of implementation of the proposed project. 4.4.1 Nesting Migratory and Native Avian Species The project area likely provides nesting habitat for nesting avian species whose nests and young are protected under the MBTA and California Fish and Game Codes. Construction activities associated with the proposed project that result in ground disturbance and/or the removal of vegetation could have both direct and indirect impacts to these sensitive resources. The breeding season for birds generally occurs from February 1 through August 31; implementation of the project during this period could result in both direct and indirect impacts to nesting avian species. Direct project impacts would include the destruction of active nests, eggs, or young located within vegetation removed within the proposed project. Indirect impacts would include noise and disturbance associated with the construction activities that cause birds in adjacent habitats to abandon their nests. Any impacts (direct or indirect) that result in the abandonment or destruction of an active nest or the destruction of eggs or young of any protected avian species, including special -status species, would be considered a significant impact under CEQA. 5. RECOMMENDATIONS 5.1 NESTING MIGRATORY AND NATIVE AVIAN SPECIES SWCA recommends that ground -disturbing and vegetation -removal activities associated with construction of the project be performed outside of the breeding season for birds, or between September 1 and January 31. If these project activities cannot be implemented during this time period, the project applicant should retain a qualified biologist to perform preconstruction nest surveys to identify active nests within and adjacent to (up to 500 feet) the project area. If the preconstruction survey is conducted SWCA Environmental Consultants 18 • • BIOLOGICAL RESOURCES ASSESSMENT TURPANJIAN PROPERTY early in the nesting season (February 1—March 15) and nests are discovered, a qualified biologist may remove the nests only after it has been determined that the nest is not active (i.e., the nest does not contain eggs, nor is an adult actively brooding on the nest). Any active non -raptor nests identified within the project area or within 300 feet of the project area should be marked with a 300-foot buffer, and the buffer area would need to be avoided by construction activities until a qualified biologist determines that the chicks have fledged. Active raptor nests within the project area or within 500 feet of the project area should be marked with a 500-foot buffer and the buffer avoided until a qualified biologist determines that the chicks have fledged. If the 300-foot buffer for non -raptor nests or 500-foot buffer for raptor nests cannot be avoided during construction of the project, the project applicant should retain a qualified biologist to monitor the nests on a daily basis during construction to ensure that the nests do not fail as the result of noise generated by the construction. The biological monitor should have the authority to halt construction if the construction activities cause negative effects, such as the adults abandoning the nest or chicks falling from the nest. 5.2 LANDSCAPING PLAN In accordance with the City's regulations, a landscape plan must be prepared for the project. SWCA recommends that graded areas where ornamental landscaping may be impracticable be vegetated with native drought -tolerant vegetation. Vegetation should be of low stature, including shrubs, subshrubs, and annual herbaceous species. In addition, the landscaping plan should conform to the County of Los Angeles' Fuel Modification Plan Guidelines (County of Los Angeles 1998). Plants selected for landscaping should be of local genetic stock. A list of suggested plant materials appropriate for the site is provided below (Table 2). Table 2.

We understand that the Property is 4 acres in size. . Scope of Work Task 1. Database/Literature Search. SWCA will review the sensitive biological resource occurrence records contained within the California Natural Diversity Database (CNDDB) and the California Native Plant Society's (CNPS) rare plant inventory. SWCA will also conduct a literature review of projects previously completed within the vicinity of the project area to gather relevant information regarding the natural resources and special -status species in the vicinity. The goal of this task will be to compile a list of special status -species occurrences within and immediately adjacent to the project area, and to aid in assessing the occurrence potential for other special -status species known from within the vicinity of the project area. In addition to special -status species information, SWCA will assemble data regarding other biological resources within the project area, including review of recent aerial photos, GAP vegetation data, USFWS critical habitat mapper and wetlands mapper, and the California watersheds mapper. SWCA will prepare a map of the project area that depicts important biological information, such as vegetation communities, wetlands, land uses, etc. SWCA will produce a biological resources map with the various resource overlays, which will be used in assessing the biological constraints within the project area. Task 2. Field Survey. SWCA will conduct a biological assessment of the project area to verify vegetation communities and habitats against recent aerial photos of the project area; verify soils against a soils map of the project area; compile a list of all plant and wildlife species observed on and directly adjacent to the project area; estimate population sizes of all organisms detected during the survey; note indications of breeding activities (dens, nests, etc.); and assess the project area for its potential to support special -status plant and wildlife species known to occur in the vicinity of the project. SWCA biologists will also verify potential wetland features visible on the aerial photos and USGS topographic maps. SWCA will not perform wetland delineations at this stage, but will identify potential wetlands that should be evaluated in future studies. The results of the vegetation mapping and habitat assessment will be used to evaluate the need for • ;VP: SWC ENVIRONMENTAL CONSULTANTS conducting focused surveys for special -status wildlife species. Should habitat for federally -listed species occur within the project area, a change order would be necessary to conduct focused surveys, if required. Task 3. Biological Resources Assessment Technical Report. Following the background research and field survey, SWCA will prepare a biological resources assessment report (report) detailing an assessment of the biological resources within the project area. The report will include 1) an introduction describing the project location and environmental setting; 2) a description of the methods used in the background research, field survey, and assessment of the potential for special -status species; 3) a description of the results of the database (CNPS/CNDDB) searches and vegetation/habitat mapping; 4) a discussion of the distribution of biological features within the project area, including vegetation communities, wildlife habitats (including movement corridors and breeding habitats), potential jurisdictional wetlands, and sensitive plant and wildlife populations, including federally -listed species; 5) an assessment of project impacts to biological resources; and 6) recommendations for focused surveys wetland delineations (if required), and/or other additional studies or mitigation measures, as necessary. The report will also include maps depicting special -status species occurrences within ten miles of the project area, vegetation/habitats with project overlay, and CNDDB Forms/CNPS Field Survey Forms for any special -status species occurrences observed within or directly adjacent to the project area. SWCA assumes that a draft of this report and figures will be submitted to Mr. Turpanjian electronically for review. Upon receipt of comments on the draft document, SWCA will incorporate Mr. Turpanjian's input and produce the final report. SWCA assumes that only one round of review will be necessary. The final report will submitted to Mr. Turpanjian and the City electronically. Should focused surveys for federally -listed species be conducted within the project area, a change order would be necessary to revise the report to include a Biological Assessment of the listed species, if required. Cost Estimate Based on thoughtful consideration of the project requirements, and a thorough estimate of the attendant labor and direct costs, SWCA's estimate for completion of the scope of work described above is $5,000.00 (not to exceed). This cost estimate includes all labor and direct expenses required to perform the work and is based on the following tasks: Task 1 — Database/Literature Search Task 2 — Field Survey Task 3 — Biological Resources Assessment Technical Report *TOTAL ESTIMATED COST Est cite $612.00 $618.00 $3,420.00 $4,650.00 Assumptions • Staff working on the project will be billed based on their current standard title and default rate at the time the work is completed.
