SECTION 1.0 INTRODUCTION
This Biological Resources Technical Report (BRTR) was prepared to determine if the proposed building of a single family residence at 3599 Lankershim Boulevard (proposed project) may have a significant impact to biological resources, thus requiring the consideration of mitigation measures or alternatives in accordance with Section 15063 of the State of California Environmental Quality Act (CEQA) Guidelines.1 1.1 PURPOSE OF THE PROPOSED PROJECT The goal of the project is to build a five-bedroom single-family residence. The location of the proposed residence is in close proximity to the property owner’s work places that are located nearby in the City of Los Angeles. The project would provide recreation areas, ventilation, exposure to sunlight, desirable city views, be located at an appropriate distance from adjacent properties, and contain a covered four-car stacked garage. The proposed project has been designed to offer the family comfortable living quarters and recreational areas within a desired Southern California neighborhood. 1.2 PURPOSE OF THE BIOLOGICAL RESOURCES TECHNICAL REPORT The purpose of this report is to provide a characterization of baseline conditions for biological resources, the regulatory framework that guides the consideration of biological resources, and the potential for the proposed project to result in significant impacts. For this assessment, biological resources are defined consistent with Appendix G to the State CEQA Guidelines. Pursuant to the Conservation and Open Space Element of the existing adopted City of Los Angeles General Plan2 and the Mulholland Scenic Parkway Specific Plan (MSPSP),3 this assessment was undertaken to determine if the proposed project would result in adverse significant impacts to biological resources. The potential for impacts to biological resources was assessed through the review of a combination of available information, including a query of the California Natural Diversity Database (CNDDB),4 the California Native Plant Society (CNPS) online inventory,5 field surveys results from 2002–2006 and October and November 2014, and a review of published literature. The proposed project would be subject to discretionary approvals by the City of Los Angeles Planning Department. Acting in its capacity as a lead agency under CEQA, the City Planning Department would need to determine the potential for the proposed project to result in significant impacts, consider mitigation measures and alternatives capable of avoiding significant impacts, and take the environmental effects of the proposed project into consideration as part of its decision-

making process. This BRTR provides the substantial evidence on which the required evaluation of feasibility, environmental analysis, and findings of fact in relation to biological resources can be made. 1.3 INTENDED AUDIENCE This BRTR has been prepared to support the analysis to determine if the proposed project is expected to result in significant impacts to biological resources, to be used by the City of Los Angeles to support the consideration of the proposed project, and whether the proposed project has the potential to result in significant impacts to biological resources requiring the consideration of mitigation measures or alternatives. CEQA requires that the information upon which the decision-making body will render their decision be made available for public review. Ultimately, the City of Los Angeles will use the environmental compliance documentation, and input from responsible and trustee agencies, and the public to advise their decision related to consideration of the proposed project. 1.4 DEFINITIONS Waters of the United States are defined as surface waters such as navigable waters and their tributaries, all interstate waters and their tributaries, natural lakes, all wetlands adjacent to other waters, and all impoundments of these waters. On April 21, 2014, the United States Environmental Protection Agency (EPA) proposed to refine the definition of waters of the United States to include all tributaries of traditional navigable waters, interstate waters, territorial seas, and impoundments of such tributaries; wetlands adjacent to the foregoing; and waters other than wetlands that are adjacent to other jurisdictional waters.6 Federal Wetlands are defined by the U.S. Army Corps of Engineers and the Environmental Protection Agency as: “Those areas that are inundated or saturated by surface or ground water 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. Wetlands generally include swamps, marshes, bogs, and similar areas.”7 State Wetlands/Streams are defined by the California Fish and Game Code. A stream is defined as a body of water that flows at least periodically, or intermittently, through a bed or channel having banks and supporting fish or other aquatic life. Wetlands are defined as areas having riparian vegetation, without regard to wetland vegetation, soils, or hydrology. Streams as defined by Mulholland Scenic Parkway Specific Plan are defined as: “The streams protected by the Specific Plan are those water courses designated by the U.S. Geological Survey (USGS) and shown on the maps available for viewing at the Department of City Planning’s Van Nuys office and the Department’s web site. A stream may include a water course having a surface or subsurface flow that supports or has supported riparian vegetation.8, 9” 6 Federal Register. Vol. 79, No. 76, Monday April 21, 2014.

Special Status Species are those afforded special recognition by federal, state, and/or local resource agencies or jurisdictions, or recognized resource conservation organizations. Special status plant and wildlife species include those federally listed or state listed as endangered, threatened, or candidate species pursuant to the federal Endangered Species Act, the California Endangered Species Act, or other regulations enforced by a federal or state agency (such as BLM or the U.S. Forest Service [USFS]); or those considered by the scientific community to be rare. For this BRTR, special status species include listed, sensitive, and locally important species. Federally Listed Species are those provided with special legal protection under the federal Endangered Species Act. A federally listed endangered species is a species that is in danger of extinction throughout all, or a significant portion, of its range. A federally threatened species is one likely to become endangered in the absence of special protection or management efforts provided by the listing. A candidate species is one that is proposed by the federal government for listing as endangered or threatened. State-listed Species are those provided with special legal protection under the California Endangered Species Act. A state-listed endangered species is a species that is in danger of extinction throughout all, or a significant portion, of its range. A state-listed threatened species is one likely to become endangered in the absence of special protection or management efforts provided by the listing. A candidate species is one that is proposed by the federal or state government for listing as endangered or threatened. Sensitive Species are those not listed by the state government as endangered, threatened, or candidate species but categorized by the state as a species of special concern or fully protected species. A California species of special concern is defined by California Department of Fish and Wildlife (CDFW) as being a wildlife species that has declining population levels, a limited range, and/or continuing threats that have made it vulnerable to extinction. For the purpose of this BRTR, those plant species recognized by California Native Plant Society are considered sensitive species (Rare Plant Rank 1A, 1B, 2A, 2B, 3, or 4) 10 This designation also includes those species listed on the California Special Animals list that are not otherwise covered by other regulations.11 It also includes species afforded protection by the County General Plan, such as some native oak trees. Species of Special Concern are species, subspecies, or distinct population of an animal (bird, mammal, fish, reptile, and amphibian) native to California that currently satisfies one or more of the following criteria: a) is extirpated from the State or, in the case of birds, in its primary seasonal or breeding role; b) is listed as federally-, but not State-, threatened or endangered; c) meets the State definition of threatened or endangered but has not formally been listed; d) is experiencing, or formerly experienced, serious (noncyclical) population declines or range retractions (not reversed) that, if continued or resumed, could qualify it for State threatened or endangered status; e) has naturally small populations exhibiting high susceptibility to risk from any factor(s), that if realized, could lead to declines that would qualify it for State threatened or endangered status.

Sensitive Plant Community is a native plant community listed on CDFW Natural Communities List as being rare within California or threatened by human actions. Nursery Site is considered habitat in which native wildlife may establish nests, maternity roosts, dens, or otherwise engage in breeding and/or the rearing of offspring. Wildlife Movement Corridors are characterized as areas of habitat that are used by wildlife for the purpose of moving between locations. Natural Community Conservation Plan (NCCP) is defined by CDFW as a plan for the conservation of natural communities that identifies and provides for the regional or area-wide protection and perpetuation of plants, animals, and their habitats. Habitat Conservation Plans (HCPs) are required by the USFWS as part of an application for an incidental “take” permit for species listed pursuant to the federal ESA. HCPs describe the anticipated effects of the proposed taking, how the impacts will be minimized and mitigated, and how the HCP is to be funded.

SECTION 2.0 PROJECT DESCRIPTION
2.1 PROJECT LOCATION The proposed project site is located on a 22,284-square-foot lot in the community of Studio City, the City of Los Angeles, County of Los Angeles, California. The proposed project is located on the U.S. Geological Survey (USGS) 7.5-minute series Burbank topographic quadrangle12 (Township 1 North, Range 14 West) within the Rancho Ex Mission de San Fernando Land Grant Boundary at an elevation of 734 to 785 feet above mean sea level (MSL). The proposed project is approximately 0.4 mile southwest of U.S. Highway 101 (Hollywood Freeway). California State Highway 2 (Santa Monica Boulevard) is approximately 3 miles to the south, and U.S. Interstate Highway 405 (San Diego Freeway) is approximately 6 miles to the west. Nearby landmarks include Universal City, which is approximately 0.6 mile northeast. The proposed project site is located at the base of a canyon that is bounded by Ventura Boulevard to the North, Fredonia Road to the east, Wrightwood Lane to the south, and Willowcrest Avenue to the west. The Assessor’s Parcel Number for the lot is 2380-005-009. Access to the site is provided by a private driveway from Lankershim Boulevard that serves one existing home and would also serve the proposed home on the subject property and another currently vacant parcel adjacent to Lankershim Boulevard. 2.2 PROJECT DESCRIPTION The proposed project is the development of a two-story single-family residence with basement (approximately 3,826 square feet) including a stacked stall, four-car garage (Figure 2.2-1, Site Plan). The project would be designed in a modern style with natural exterior finish materials. The project would include a swimming pool, outdoor living areas (barbeque area and patio), a landscaped area, open space, a fence surrounding the property, and an entrance gate that conforms to local tradition, the climate, and the surrounding environment. The layout of the house would follow the natural grade by creating different levels and outdoor spaces in order to blend with the natural topography. A backyard retention wall (maximum height of 10 to 12 feet) would be designed to protect the building from mudslide and debris, and to divert rainwater. The foundation of the house would be composed of concrete footings and pads. The infrastructure system would consist of a wood structure and slab constructed at grade with movement-resistant frames and plywood shear walls. The roof would be constructed using “Class A,” fire retardant, roofing material in accordance with the Los Angeles Department of Building and Safety Codes. The design of the structure would comply with the Los Angeles Building Code 2002 Edition and the City of Los Angeles Fire Department’s requirements for water service, hydrant location, distance from the nearest fire station/installation of substitute watering sources, street width, access, turnaround, and brush clearance as required by the Los Angeles Municipal Code 57.21.07.

2.3 IMPACT AREA This BRTR assesses the maximum impact area associated with the proposed project area. The project footprint covers 0.22 acres, including the driveway (0.04 acres), house/patio (0.1 acres), and a 15-foot wide construction zone (0.08 acres) around the edge of the house to provide sufficient space for the construction crews of the residence. The construction zone has been limited to 5 feet wide, adjacent to the riparian habitat, in order to minimize and avoid impacts. It is anticipated that after the completion of the residence, the construction zone would be landscaped by the property owner; therefore, the construction zone has been included as a permanent impact area.

SECTION 3.0 REGULATORY FRAMEWORK
This regulatory framework identifies the federal, state, and local statutes, ordinances, policies, and guidelines that govern the conservation and protection of biological resources for the proposed Residence in the community of Studio City (proposed project). During the decision-making process, the City of Los Angeles and other regulatory agencies will utilize the regulatory framework discussed in this section to consider the potential for the proposed project to result in significant impacts to biological resources. 3.1 FEDERAL 3.1.1 Federal Endangered Species Act The federal Endangered Species Act (ESA) defines and lists species as “endangered” and “threatened” and provides regulatory protection for the listed species. The federal ESA provides a program for conservation and recovery of threatened and endangered species; it also ensures the conservation of designated critical habitat that the United States Fish and Wildlife Service (USFWS) has determined is required for the survival and recovery of these listed species. Section 9 of the federal ESA prohibits the “take” of species listed by USFWS as threatened or endangered. Take is defined as follows: “to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect or attempt to engage in such conduct.” In recognition that take cannot always be avoided, Section 10(a) of the federal ESA includes provisions for take that is incidental to, but not the purpose of, otherwise lawful activities. Section 10(a)(1)(B) permits (incidental take permits) may be issued if take is incidental and does not jeopardize the survival and recovery of the species. As defined in the federal ESA, individuals, organizations, states, local governments, and other nonfederal entities are affected by the designation of critical habitat only if their actions occur on federal lands; require a federal permit, license, or other authorization; or involve federal funding.13 At this time, it is not anticipated that the proposed project involves federal lands; federal permit, licenses, or other authorizing; or federal funding. Due to the potential presence of federally listed species in the vicinity of the proposed project property, project compliance with the federal ESA was considered in this evaluation. 3.1.2 Migratory Bird Treaty Act The Migratory Bird Treaty Act (MBTA) makes it unlawful to pursue, capture, kill, or possess any migratory bird or part, nest, or egg of any such bird listed in wildlife protection treaties between the United States, Great Britain, Mexico, Japan, and Russia (formerly the Soviet Union). 14 Similar to the federal ESA, the MBTA authorizes the secretary of the interior to issue permits for incidental take. Due to documented presence of resident and migratory birds within the proposed project property, project compliance with the MBTA was considered in this evaluation. Nesting birds and the

contents of the nest within the proposed project property are afforded protection during the nesting season pursuant to the MBTA. 3.1.3 Section 404 of the Federal Clean Water Act Section 404 of the federal Clean Water Act, which is administered by the U.S. Army Corps of Engineers (USACOE), regulates the discharge of dredged and fill material into waters of the United States. USACOE has established a series of nationwide permits that authorize certain activities in waters of the United States, provided that a proposed activity can demonstrate compliance with standard conditions. Generally, USACOE requires an individual permit for an activity that will affect an area per crossing equal to or in excess of 0.3 acre of waters of the United States. Impacts less than 0.3 acre of waters of the United States per crossing can normally be conducted pursuant to one of the nationwide permits, if consistent with the standard permit conditions. Use of any nationwide permit is contingent on the activities that have no impacts to endangered species. The project has been documented to contain a series of springs, but there are no National Wetlands Inventory (NWI) wetlands documented on site. The springs within the project property have been evaluated to determine if they feed into navigable waters of the United States; therefore, the federal Clean Water Act was taken into consideration in the evaluation of the proposed project due to the potential for the project to impact federal jurisdictional drainages and wetlands within the project property during construction. 3.2 STATE 3.2.1 California Endangered Species Act The California ESA (California Fish and Game Code §§ 2050 et seq.) prohibits the take of listed species, except as otherwise provided in state law. The take for the California ESA is defined as it is in the federal ESA; however, unlike the federal ESA, the California ESA also applies the take prohibitions to species petitioned for listing as state candidates rather than only listed species. State lead agencies are required to consult with the California Department of Fish and Wildlife (CDFW) to ensure that any actions undertaken by the lead agency are not likely to jeopardize the continued existence of any state-listed species or result in destruction or degradation of required habitat. CDFW is authorized to enter into Memoranda of Understanding (MOUs) with individuals, public agencies, universities, zoological gardens, and scientific or educational institutions to import, export, take, or possess listed species for scientific, educational, or management purposes. Due to the potential presence of state-listed rare, threatened, endangered, or candidate species within the proposed project property, compliance with the California ESA was considered in the evaluation of the proposed project. 3.2.2 Sections 2080 and 2081 of the State Fish and Game Code Section 2080 of the State Fish and Game Code (Code) states,
No person shall import into this state [California], export out of this state, or take, possess, purchase, or sell within this state, any species, or any part or product thereof, that the commission [State Fish and Game Commission] determines to be an endangered species or threatened species, or attempt any of those acts, except as

otherwise provided in this chapter [Chapter 1.5, Endangered Species], or the Native Plant Protection Act, or the California Desert Native Plants Act.15
Pursuant to Section 2081 of the Code, the CDFW may authorize individuals or public agencies to import, export, take, or possess any state-listed endangered, threatened, or candidate species. These otherwise prohibited acts may be authorized through permits or MOUs as follows: (1) if the take is incidental to an otherwise lawful activity, (2) if impacts of the authorized take are minimized and fully mitigated, (3) if the permit is consistent with any regulations adopted pursuant to any recovery plan for the species, and (4) if the applicant ensures adequate funding to implement the measures required by CDFW. CDFW shall make this determination based on available scientific information and shall include consideration of the ability of the species to survive and reproduce. Due to the potential presence of state-listed rare, threatened, endangered, or candidate species within the proposed project property, Sections 2080 and 2081 of the Code were considered in the evaluation of the proposed project. 3.2.3 Native Plant Protection Act The Native Plant Protection Act includes measures to preserve, protect, and enhance rare and endangered native plants. The list of native plants afforded protection pursuant to the Native Plant Protection Act includes those listed as rare and endangered under the California ESA. The Native Plant Protection Act provides limitations that no person will import into the state—or take, possess, or sell within the state—any rare or endangered native plant, except in compliance with provisions of the act. Individual landowners are required to notify the CDFW at least 10 days in advance of changing land uses to allow the CDFW to salvage any rare or endangered native plant material. Due to the potential presence of rare and endangered native plants within the proposed project property, the Native Plant Protection Act was considered in the evaluation of the proposed project. 3.2.4 Sections 3503 and 3503.5 of the State Fish and Game Code These sections of the Code provide regulatory protection to resident and migratory birds and all birds of prey within the State of California, including the prohibition of the taking of nests and eggs, unless otherwise provided for by the Code. Specifically, these sections of the Code make it unlawful to take, possess, or needlessly destroy the nest or eggs of any bird, except as otherwise provided by the Code. Due to the potential presence of resident and migratory nesting birds within the proposed project property, Sections 3503 and 3503.5 of the Code were considered in the evaluation of the proposed project. 3.2.5 Sections 1600 through 1603 of the State Fish and Game Code All diversions, obstructions, or changes to the natural flow or bed, channel, or bank of any river, stream, or lake in California are subject to the regulatory authority of CDFW pursuant to Sections 1600 through 1603 of the Code and require preparation of a Streambed Alteration Agreement.

Pursuant to the Code, a stream is defined as a body of water that flows at least periodically, or intermittently, through a bed or channel having banks and supporting fish or other aquatic life. Based on this definition, a watercourse with surface or subsurface flows that support or have supported riparian vegetation is a stream and is subject to CDFW jurisdiction. Altered or artificial waterways valuable to fish and wildlife are subject to CDFW jurisdiction. Due to the presence of springs on the proposed project property, Sections 1600 through 1603 of the Code were considered in the evaluation of the proposed project. 3.3 LOCAL 3.3.1 City of Los Angeles General Plan The City of Los Angeles General Plan includes the following policies related to biological resources:
Require evaluation, avoidance, and minimization of potential significant impacts, as well as mitigation of unavoidable significant impacts on sensitive animal and plant species and their habitats and habitat corridors relative to land development activities
Identify significant habitat areas, corridors and buffers and to take measures to protect, enhance and/or restore them
Work cooperatively with other agencies and entities in protecting local habitats and endangered, threatened, sensitive and rare species
Specifically, there are two policies that are applicable to the development of single-family residences.16 All other sections of the City of Los Angeles General Plan do not apply to the biological resources on the proposed project site. Section 6, Policy 1: continue to require evaluation, avoidance, and minimization of potential significant impacts, as well as mitigation of unavoidable significant impacts on sensitive animal and plant species and their habitats and habitat corridors relative to land development activities. Section 12, Policy 1: continue to identify significant habitat areas, corridors and buffers and to take measures to protect, enhance and/or restore them.
3.3.2 Sherman Oaks–Studio City–Toluca Lake–Cahuenga Pass Community Plan The Sherman Oaks–Studio City–Toluca Lake–Cahuenga Pass Community Plan portion of the City of Los Angeles General Plan17 had no additional regulations or policies on biological resources. The project applicant will be required to demonstrate compliance with the goals of the City of Los Angeles General Plan during the project entitlement process.

3.3.3 Protected Tree Ordinance The City of Los Angeles has issued a protected tree ordinance No. 177404 that protects oaks, such as valley oak (Quercus lobata) and coast live oak (Q. agrifolia); Southern California black walnut (Juglans californica var. californica); western sycamore (Platanus racemosa); and California bay (Umbellularia californica) from relocation, removal, or any act that may result in the death of a protected tree without authorization. Further limitations prohibit construction activity within the dripline of a protected tree. Due to the presence of protected trees on the proposed project property, ordinance No. 177404 was considered in the evaluation of the proposed project. 3.3.4 Mulholland Scenic Parkway Specific Plan The Mulholland Scenic Parkway Specific Plan (MSPSP) has measures in place for potential development projects up to ½ mile away to ensure compatibility with the environment. These measures include restrictions on grading along prominent ridges, construction within a designated distance of a stream bank without approval, removal of oak trees without approval, and restrictions on plant species approved in landscaping. The proposed project lies within the outer corridor of the MSPSP; therefore, the MSPSP was considered in the evaluation of the proposed project. The proposed project site is located within the outer corridor of the MSPSP. Several of the protection measures do not apply to the proposed project, such as parklands, which are not within 200 feet of the proposed project site. As such, the following environmental protection measures could apply to the proposed project site:
1) Streams: No project shall be constructed and no more than 100 cubic yards of earth shall be moved within 100 feet of either stream bank without the prior written approval of the Director pursuant to Section 11. In granting an approval, the Director shall make the following findings: a. The applicant has employed a biologist to prepare a report which contains
the following: the location(s) of the stream's banks, an assessment of the riparian resources, an evaluation of the project's impact on the riparian resources and a recommendation of feasible mitigation measures.
b. The applicant has submitted to the Director for his approval, a copy of the biologist's report and a covenant and agreement which runs with the land and which states that the mitigation measures recommended by the biologist and approved by the Director will be incorporated in the project and maintained. The covenant and agreement shall be recorded by the applicant.
c. The project preserves the natural vegetation and the existing ecological balance.
d. The project protects prominent ridges, streams, and environmentally sensitive areas and the aquatic, biologic geologic and topographic features therein.
e. The project will not damage the integrity of a stream.

2) Oak Trees: No oak tree (Quercus agrifolia, Q. lobata, Q. virginiana) shall be removed, cut down or moved without the prior written approval of the Director. The Director may approve the removal, cutting down or moving of an oak tree after making the following findings: a. The removal, cutting down or moving of an oak tree will not result in
undesirable, irreversible soil erosion through diversion or increased flow of surface waters.
b. The oak tree is not located with reference to other trees or monuments in such a way as to acquire a distinctive significance at said location.
3.4 AUTHORIZATIONS, PERMITS, REVIEWS, AND APPROVALS This section summarizes the authorizations, permits, reviews, and approvals required for the proposed project that pertain to biological resources. State, local, and federal discretionary entitlements that may be required include:
CDFW Streambed Alteration Agreement Pursuant to Section 1600 of the State Fish and Game Code
Los Angeles Regional Water Quality Control Board Water Quality Certification pursuant to Section 401 of the Federal Clean Water Act
Approval from the Director of the City Planning Department City of Los Angeles Building Permit

SECTION 4.0 METHODS
This section describes the methods for surveys conducted in 2014. Prior to surveys, Sapphos Environmental, Inc. conducted a review of the existing data collected from previous visits to the proposed project site on April 15, 2002; January 22, 2003; April 23, 2004; March 10, 2005; June 8, 2005; and March 28, 2006.18,19,20,21,22 4.1 SENSITIVE PLANT AND ANIMAL SURVEYS Plant and wildlife records from the CNDDB were searched prior to any field surveys to establish species that have the potential to occur in the proposed project site. In 2003, Sapphos Environmental, Inc. searched CNDDB records for potentially sensitive species within the Burbank U.S. Geological Survey (USGS) 7.5-minute series topographic quadrangle. In 2014, Sapphos Environmental, Inc. expanded the search area by including all CNDDB records within a 10-mile radius around the project, which hereafter is referred to as the project vicinity. Searching the larger radius allows for a more thorough assessment of potentially occurring sensitive species and impacts that may occur as a result of the proposed project. In addition, the following databases were queried for additional records for sensitive plants and animals: CNPS, Consortium of California Herbaria (Herbaria), and eBird. Based on the CNDDB query of plant and wildlife records within 10 miles, the proposed project site is within the historical range of 51 listed and sensitive species (24 plant and 27 wildlife species; Appendix A, CNDDB Records within 10 Miles). As a result of further literature and record searches, two bird species were added to the list of potential species. However, 15 species (13 plant and 2 wildlife species) have been extirpated or presumed extirpated because of the high-level of development in the area; there was no evidence to suggest that these species are still extant on the proposed project site, supported by surveys conducted from 2002–2006 and in 2014. Therefore, habitat on the proposed project site was evaluated for 38 species (5 listed and 33 sensitive) with nearby extant populations, but only 8 species needed directed surveys after the habitat evaluation was performed.

On October 9, and 23, 2014, two Sapphos Environmental, Inc. biologists performed plant and wildlife surveys. One botanist performed a floristic survey of the entire property, by identifying all species of trees, shrubs, and forb observed on the proposed project site and immediately adjacent parcels.23 Given the small size of the parcel, plants were surveyed by walking the entirety of the property (area search) rather than transects. For herbaceous plants that were not currently flowering and could not be identified, the plants were collected by a botanist (Permit #2081(a)-13-2-V) and compared to sensitive plants to determine if the unknown forbs were sensitive species. For plant species that had habitat on the proposed project site and a fall bloom period, reference sites were visited.24 Oak tree larger than 3 inches in diameter at breast height (DBH) on the proposed project site had been previously tagged on March 28, 2006; therefore, evaluation in 2014 was simply to determine if each oak tree was present and determine the extent of their dripline. Plant species were identified using The Jepson Manual: Vascular Plants of California25 On October 9 and 23, 2014, a second biologist walked the entire parcel looking for wildlife species, including reptiles, birds, and mammals on the proposed project site and immediately adjacent parcels. Wildlife surveys consisted of area searches to ensure complete coverage of the site and to observe sign of wildlife usage within the proposed project area. Presence of wildlife and wildlife sign were noted and recorded. In addition, a bat roost survey was conducted at twilight on November 17, 2014 to search for tree roosting bat species. Two bat biologists used an Anabat SD2 acoustic bat detector to record bat calls as they searched trees and any tree cavities for sign of guano. Sunset was 4:47 p.m., and bats were surveyed from 4:15 to 5:45 p.m. in order to increase the likelihood of detecting bats during the emergence period. All survey personnel were experienced in the undertaking of field surveys for wildlife species, as well as knowledgeable about the identification and ecology of species within the area of the proposed project area.

survey personnel were familiar with both federal and state statutes related to listed and sensitive wildlife species. All plant and animal species observed were compiled into a compendium (Appendix B, Floral and Faunal Compendium). 4.2 PLANT COMMUNITY SURVEYS Surveys of plant community type were conducted previously on April 15, 2002; January 22, 2003; April 23, 2004; March 10, 2005; and March 28, 2006 by Sapphos Environmental, Inc.26,27,28 However, these surveys used the Holland Classification System based on the Preliminary Descriptions of the Terrestrial Natural Communities of California.29 The Holland Classification system is no longer used by CNPS or CDFW. Instead, the current CDFW list of sensitive natural communities30 is based on A Manual of California Vegetation, second edition (MCV).31 Therefore, the plant communities on the proposed project site and adjacent parcels were reclassified based on MCV on October 9, 2014 and boundaries verified on October 23, 2014 in order to update the plant community to the current classification system. Sapphos Environmental, Inc. used the CNPS and CDFW approved Relevé method to assess the plant communities, in which the percent cover of all plant species within a plot is determined. Sapphos Environmental, Inc. used a 100-square-meter plot (10x10 meters), which is smaller than the recommended plot size of 1,000 square meters, but the small parcel size prohibited the use of the larger plots within existing plant communities. The parcel was first walked to determine potential stands and to determine locations that best represented the structure and composition in each stand within the parcel.32 Four plots were placed to assess four potential plant communities. A fifth plant community (Mulefat Scrub) primarily exists adjacent to the parcel and was not assessed using Relevé methods; however, the boundary of this plant community was delineated on October 9 and 23, 2014. Sapphos Environmental, Inc. recorded locational information (site, elevation, exposure, and slope) about the plot using an Ashtech Mobile Mapper GPS unit and compass. Soil texture and topography were determined on site, and the geology code was determined from existing records of the area. Standing from the southwest corner of the plot, photographs were taken clockwise in the four cardinal directions (north, east, south, and west) with additional photos of the canopy and across the plot facing the

northeastern corner.33 Surface cover of the abiotic substrates was estimated as water, basal area of stems, litter, bedrock, boulders (>60 centimeter diameter), stones (25-60 centimeter diameter), cobble (7.5-25 centimeter diameter), gravel (0.2-7.5 centimeter diameter), and fine sediments.34 Notes were taken about the stand history, disturbance, evidence of fire, bioturbation of underground mammals, and area punched down by hooves.35 Finally, percent cover of each species within the plot was recorded; plants with <1% cover were denoted with a “+” symbol. The boundary of the plant communities was mapped with the Ashtech GPS, and the data were post-processed to generate the highest spatial accuracy possible for the community limits. Mapping occurred on October 9, 2014 and was then further verified on October 23, 2014. The data collected on species composition were then compared to the community requirements within MCV to determine the plant community type and rarity. 4.3 JURISDICTIONAL DELINEATION Sapphos Environmental, Inc. used a combination of literature and database review, followed by field verification, to delineate non-wetland waters by identifying the Ordinary High Water Mark (OHWM). Sapphos Environmental, Inc. reviewed NWI Maps,36 the Burbank USGS 7.5-minute series topographic quadrangle map,37 and the previously prepared USACOE38 determination and Streambed Alteration Agreements (SAA)39,40,41 to assess the existing conditions on site. The OHWM is defined as “that line on the shore established by the fluctuation of water and indicated by physical characteristics such as a clear, natural line impressed on the bank; shelving; changes in the character of the soil; destruction of terrestrial vegetation; the presence of litter and debris; or other appropriate means that consider the characteristics of the surrounding areas.”42 Additional guidance was issued by the USACOE in 2005 to clarify the meaning of “or other appropriate means that consider the characteristics of the surrounding areas.” The USACOE further states that the following characteristics should be considered: wracking, matted down or bent vegetation, sediment sorting, leaf litter disturbed or washed away, scour, deposition, multiple observed flow events, bed and banks, water staining, and changes in plant communities.43 Based on the USACOE, an area is determined to be a federal wetland if “evidence of a minimum of one positive wetland indicator from each parameter (hydrology, soil, and vegetation) must be found in order to make a positive wetland determination.”44

Therefore, federal wetlands have three diagnostic features: 1) Vegetation: Dominated by plants composed of hydrophytic species that can grow in
anaerobic soil conditions.45,46 2) Soils: Presence of hydric soils or soils that possess characteristics of reduced soil
conditions. 3) Hydrology: An area permanently or periodically inundated with water to a depth of less
than 6.6 feet. CDFW’s jurisdiction is similar to that of the USACOE, but differs in placing more emphasis on habitat function and value and less on the OHWM. Riparian plant communities often fall under CDFW jurisdiction and occur above the ordinary high water level. CDFW jurisdictional wetlands (one subset of riparian habitats) do not need to exhibit the three criteria associated with federal jurisdiction (wetland hydrology, hydrophytic vegetation, and hydric soils). Pursuant to Sections 1600 through 1603 of the California Fish and Game Code, all diversions, obstructions, or changes to the natural flow or bed, channel, or bank of any river, stream, or lake in California are subject to the regulatory authority of CDFW. A field evaluation by Sapphos Environmental, Inc. was conducted on October 9, 2014 and October 23, 2014. The evaluation was completed by a wetland delineator certified by the Wetland Training Institute47 in accordance with the USACOE region-specific guidance for the Arid West48 and guidelines set forth by CDFW.49 The site assessment was performed by first looking for the OHWM along the entirety of a small drainage that bisects the property and then checking the upstream and downstream portions of the drainage. The results of the field verification were transferred to digital format using GIS software, for subsequent use in analyses. The botanist marked the boundaries of potential wetlands based on the presence of wetland/riparian plant species and/or bed and bank. Wetland boundaries and sampling locations were recorded using an Ashtech GPS unit with sub-meter accuracy. Within potential wetlands, a certified wetland delineator recorded vegetation, soil, and hydrology data as outlined in the standard USACOE data forms. Vegetation, soils, and hydrology were sampled at two locations: 1) in the center of the potential wetland and 2) at the location where water had been previously documented as pooled.50,51 The position of each sampling location was recorded using a GPS unit. 45 United States Army Corps of Engineers. 1987.

Each sampling point was classified as wetland or non-wetland based on the presence of hydrophytic plants, hydric soil, and wetland hydrology. Hydrophytic vegetation was determined based on visual estimates of percent cover in plots at sampling location. Plant species observed at potential wetlands were identified using The Jepson Manual: Vascular Plants of California52 and categorized based on their tendency to occur in wetlands or uplands.53Soil test pits were combined with vegetation sampling points where deemed necessary. At each sampling location, the depth, color, and texture of the soil, matrix, and redoximorphic features—spots of different colors within the dominant color of the layer—were documented. The soil from each pit was examined for hydric soil indicators, including low chroma, iron or manganese concentrations, organic layers, gleization, sulfuric odor, and so forth, as listed on the Data Form as primary hydric soil indicators. The soil pits were dug to a depth of approximately 20 inches whenever possible. The soil color was determined from moist soil samples using the Munsell Soil Color Charts.54 The Pocket Guide to Hydric Soil Field Indicators was used to assess the hydric soils at each pit.55 The entirety of the potential wetland was searched for wetland hydrological indicators. 4.4 MIGRATORY COORIDOR On October 9, 2014, five wildlife cameras were placed on the proposed project site to observe potential wildlife trails (Figure 4.4-1, Location of Wildlife Cameras). Wildlife cameras were placed along apparent game trails and aimed away from existing houses, such that only undeveloped areas were visible. Wildlife cameras had a sensor, such that when wildlife passed by the camera, the wildlife camera would take one photograph and then a short video. The wildlife cameras were removed on October 23, 2014 (14 days). All photos and video were reviewed for evidence of an animal. 4.5 ORDINANCES Sapphos Environmental, Inc. reviewed state policies and regulations on oak woodlands, the state Fish and Game Code, the Los Angeles General Plan, the City of Los Angeles ordinances, and the MSPSP in order to determine if the proposed project was in conflict with any of the policies specific to biological resources. 4.6 HCPs Sapphos Environmental, Inc. reviewed the boundaries of any Habitat Conservation Plan (HCP) or Natural Community Conservation Plan (NCCP) in relation to the proposed project site using CDFW’s NCCP California Regional Conservation Plans Map.56

SECTION 5.0 RESULTS
5.1 EXISTING CONDITIONS The proposed project site is located in a residential neighborhood and surrounded by development. Indeed, there are only three parcels that have not been developed, including the proposed project site (Figure 5.1-1, Developed and Vacant Parcels). All of the other surrounding parcels have had houses built on more than half of the parcel. However, a small woodlot is present because owners have chosen not to build on the remaining half of the occupied parcel (Figure 5.1-1). The proposed project would be consistent with the current development by building on no more than half of the parcel and leaving the other half undeveloped for wildlife. 5.1.1 Special-status Species: Listed, Candidate, and Sensitive Species There were extant populations for 38 species (5 listed and 33 sensitive) within 10 miles of the proposed project (Figure 5.1.1-1, CNDDB Records of Extant Populations; Figure 5.1.1-1a, CNDDB Records of Extant Plants and Plant Communities; Figure 5.1.1-1b, CNDDB Records of Extant Wildlife). Federally and State Listed Species Habitat Evaluation Based on the habitat evaluation conducted in 2002–2006 and reviewed in 2014 for the five listed species with extant populations within 10 miles of the proposed project, there was no habitat present for all five federally or state-listed endangered and threatened species (two plant and three bird species; Table 5.1.1-1, Federally and State Listed Species in the Project Vicinity). Rare plant surveys for Nevin’s barberry (Berberis nevinii) and slender-horned spineflower (Dodecahema leptoceras) determined that these species was absent and would not be expected to occur due to the lack of suitable sandy or gravelly wash habitat at the proposed project site.57,58,59,60 Coastal California gnatcatcher (Polioptila californica californica) was determined to be absent from the proposed project site and the “coastal scrub” (i.e., laurel sumac scrub) on site is not habitat because the plant community is too small to support this species; the 1.0 acre of “coastal scrub” with and adjacent to the proposed project site is less than the California gnatcatcher home range size of 4 and 11 acres61 (Figure 5.1.1-2, Coastal Scrub Habitat Location; Figure 5.1.1-3, Coastal Scrub Habitat). Likewise, the proposed project is within the historical range of southwestern willow flycatcher (Empidonax traillii extimus) and least Bell’s vireo (Vireo bellii pusillus), but these species are absent and have no habitat because both species need river bottoms with a dense understory

dominated by shrubby willows, cottonwoods, and similar associated species.62,63,64,65 In contrast, the riparian habitat (i.e., an arroyo willow thicket) on and adjacent to the proposed project site is small (0.2 acre), isolated from other riparian areas, and lacking understory, meaning the proposed project site is not habitat for willow flycatcher or Bell’s vireo (Figure 5.1.1-4, Riparian Habitat Location, Figure 5.1.1-5, Riparian Habitat).66,67,68,69 Therefore, the proposed project would not impact federally or state listed species or their habitat.

SPECIES IN THE PROJECT VICINITY
Species Special Status
Status at Proposed Site Habitat Requirements and Historic Records
Plants
Nevin’s barberry (Berberis nevinii)
FE, SE, 1B.1
Absent/ No habitat
Preferred habitats include sandy and gravelly areas along margins of dry washes in the foothills of the Transverse and Peninsular Ranges below 2,000 feet in chaparral, coastal sage, cismontane woodland, and riparian scrub communities.70,71 One record is presumed to be a transplanted population in Griffith Park below water tower #113 along Vista Del Valle Road; this is the only record in the Santa Monica Mountains. Two naturally occurring records were from the Verdugo Mountains in Big Tujunga Wash and Wildwood Canyon.
slender-horned spineflower (Dodecahema leptoceras)
FE, SE, 1B.1
Absent/ No habitat
Preferred habitats include chaparral, coastal sage scrub, alluvial fan sage scrub, often found along flood deposited terraces and washes; once known from more than a dozen locations on outwash alluvial fans and terraces from the San Fernando Valley east along the San Gabriel Mountains frontage to the San Bernardino Valley and to Riverside County.72 Two records from within the Crescenta Valley; one record population is possibly extirpated due to development of La Crescenta-Montrose, but the second record in Big Tujunga Wash is likely extant.
Birds southwestern willow flycatcher (Empidonax traillii extimus)
FE, SE Absent/ No habitat
Requires riparian woodland and breeds in relatively dense riparian tree and shrub communities associated with rivers, swamps, and other wetlands. Habitat patches must be at least 0.25 acre in size and at least 9 m (30 ft) wide. One CNDDB record within 10-miles was from 1894. No habitat on the proposed project site given the riparian area is 0.1 acre and lacks understory.
least Bell's vireo (Vireo bellii pusillus)
FE, SE Absent/ No habitat
Habitat is riparian forest, riparian scrub, and riparian woodland with dense understory, which is required for nesting. Nests usually 1 m (3 ft) above ground. Population in Los Angeles County is increasing, with recent CNDDB records at Hansen Dam and Sepulveda Basin and numerous other eBird records in appropriate habitat. No habitat exists on the proposed project site given the riparian area is 0.1 acre and lacks understory.
coastal California gnatcatcher (Polioptila californica californica)
FT, SSC
Absent/ No habitat
A locally uncommon, non-migratory obligate nester of dense coastal sage scrub habitats occurring below or on arid hillsides, mesas, and washes. Its distribution is fragmented and restricted to Southern California; historical range extends from the southernmost coastal counties of Ventura, Los Angeles, Orange, San Diego, San Bernardino, and Riverside. Most recent records within 10 miles have been near Hansen Dam and Tujunga Valley. No habitat exists on the proposed project site given the level of surrounding development, plant community structure, and coastal scrub is about 1 acre.

Sensitive Species Habitat Evaluation Based on the habitat evaluation conducted in 2002–2006 and reviewed in 2014 for the 33 sensitive species with extant populations within 10 miles of the proposed project, there was no habitat for 25 of the 33 species of rare plants, species of special concern, or designated California special animals with species. The following species did not have habitat and would not occur:
Southern tarplant (Centromadia parryi ssp. australis), Coulter’s goldfields (Lasthenia glabrata ssp. coulteri), and Parish’s brittlescale (Atriplex parishii) because saline or alkaline wetlands were absent.
White rabbit-tobacco (Pseudognaphalium leucocephalum) because dry streambeds and washes were absent.
Plummer's mariposa-lily (Calochortus plummerae) because granitic and rocky soils were absent.
Mesa horkelia (Horkelia cuneata var. puberula) because the habitat is sandy or gravelly soils in maritime chaparral, cismontane woodland, and coastal scrub, especially foothills edges of the Los Angeles Basin. Recent records have only been along the foothills of the San Gabriel Mountains.
Nuttall’s scrub oak (Quercus dumosa) because the location of the CNDDB record is only “true,” un-hybridized Nuttall’s scrub oak in Los Angeles County. An oak survey on the site documented that only coast live oak and scrub oak were present on the parcel.73
Monarch butterfly (Danaus plexippus) roosts because Eucalyptus trees were absent. The distance from the coast and no sightings of this species in the fall 2014 surveys provide further evidence that no autumnal or winter roost occurs on the proposed project site.
Gertsch's socalchemmis spider (Socalchemmis gertschi) because records indicate that this species was first recognized as a species in 2001 from four museum specimens collected from 1936–1997 in the Santa Monica Mountains, mostly near Topanga Canyon.74 Scant other details exist on habitat requirements; therefore, this species was considered absent on the proposed project site.
Arroyo chub (Gila orcuttii), Santa Ana speckled dace (Rhinichthys osculus ssp. 3), western pond turtle (Emys marmorata), two-striped garter snake (Thamnophis hammondii), and south coast marsh vole (Microtus californicus stephensi) because freshwater wetlands or flowing water was absent.
Silvery legless lizard (Anniella pulchra pulchra) because looser soil types generally associated with active dune or old dune complexes were absent.
Burrowing owl (Athene cunicularia), San Diego black-tailed jackrabbit (Lepus californicus bennettii), and American badger (Taxidea taxus) because flat, open terrain was absent.
Peregrine falcon (Falco peregrinus) because there is no nesting or foraging habitat on the proposed project site given that these birds require open area in which to

hunt and cliffs or tall buildings for nesting.75,76 Further, their primary prey (i.e., ducks and pigeons) was absent from the proposed project site, and the forested community would be difficult for peregrine falcon to forage within because they hunt by diving at prey at an excess of 200 miles per hour.77 Even though nearby residents claimed to have observed peregrine falcon in the past,78 the observation would have been of a flyover (i.e., bird over the site but not using the habitat) or a misidentified raptor.
Western yellow bat (Lasiurus xanthinus) and roosts because palms and more arid environments were absent.
Western mastiff bat (Eumops perotis californicus) and big free-tailed bat (Nyctinomops macrotis) because rocky crevices were absent; furthermore, western mastiff bat generally avoids highly developed areas, such as the area surrounding the proposed project site.
Southern grasshopper mouse (Onychomys torridus ramona) because chenopod scrub in more arid environments was absent.
Los Angeles pocket mouse (Perognathus longimembris brevinasus) because the populations within the San Fernando Valley may all be extirpated.79
San Diego desert woodrat (Neotoma lepida intermedia) because habitat is coastal scrub, sagebrush scrub, chaparral often associated with large cactus patches. Although it can occur in oak woodlands, these woodlands have rocky outcroppings with crevices suitable for midden building; there were no rocky outcropping present that had crevices.
Directed Survey Of the 38 species with extant populations within 10 miles of the proposed project, only eight species had habitat on the proposed project site (Table 5.1.1-2, Sensitive Species with Habitat on the Proposed Project Site). The entire site is potential habitat for Davidson's bush-mallow (Malacothamnus davidsonii), Cooper’s hawk (Accipiter cooperii), silver-haired bat (Lasionycteris noctivagans), hoary bat (Lasiurus cinereus), and pallid bat (Antrozous pallidus). In addition, only the chaparral/coast sage scrub areas have habitat for slender mariposa-lily (Calochortus clavatus var. gracilis), coast horned lizard (Phrynosoma blainvillii), and coastal whiptail (Aspidoscelis tigris stejnegeri). Of these 8 species, 7 were determined to be absent based on directed surveys in 2002–2006 and 2014 (Table 5.1.1-2); only the Cooper’s hawk was observed to be present on the proposed project site.

Species Rarity Rank
Status at Proposed
Site Habitat Requirements and Historic Records Plants
Davidson's bush-mallow (Malacothamnus davidsonii)
1B.2 Absent/ Habitat present
The habitat is chaparral, cismontane woodland, coastal scrub, and riparian woodland on slopes and washes.80,81 The majority of records within Los Angeles County are on south-facing slopes on the northern edges of San Fernando Valley. No records exist from the Santa Monica Mountains. The laurel sumac scrub on site is marginal habitat. Bush mallows are evident at this time of the year; reference population visited.
slender mariposa-lily (Calochortus clavatus var. gracilis)
1B.2 Absent/ Habitat present
The habitat is chaparral plant communities in the shaded foothill canyons.82,83 There is limited chaparral plant community on the proposed project site, and community structure is less favorable for this species. The laurel sumac scrub is habitat, but a site visit to a reference population indicates that the proposed project site is not optimal habitat.
Reptiles
coast horned lizard (Phrynosoma blainvillii)
SSC Absent/ Habitat present
Habitat is coastal scrub, coastal bluff scrub, valley and foothill grassland, chaparral, cismontane woodland, pinyon and juniper woodlands, riparian scrub, riparian woodland and desert. Habitat is low quality and only within the open areas around the laurel sumac scrub; the closed canopy throughout a majority of the parcel is not habitat for this species.
coastal whiptail (Aspidoscelis tigris stejnegeri)
CSA Absent/ Habitat present
Occurs in open habitats that are primarily hot and dry with sparse foliage in chaparral, woodland, and riparian areas. Vegetation is generally too dense, and the location of the proposed project site within a north-facing canyon is likely too cool for this species. Habitat is low quality and only within the open areas around the laurel sumac scrub; the closed canopy throughout a majority of the parcel is not habitat for this species.
Birds
Cooper’s hawk (Accipiter cooperii)
CSA Present
Often found in suburban areas with interspaced woodlots or large planted trees. This forest hawk is adapted at hunting prey from under the forest canopy and within brush. Commonly hunts small birds at backyard feeders.
Mammals
silver-haired bat (Lasionycteris noctivagans)
SSC Absent/ Habitat present
Habitat is primarily forested areas adjacent to lakes, ponds, or streams. Roosts and nursery sites are in tree foliage, cavities, or under loose bark. Large trees suitable for roosting and foraging are present on the proposed project site.

Plants Davidson’s bush mallow is a shrub that primarily grows on the north side of San Fernando Valley on south-facing slopes of the foothills of the San Gabriel Mountains. It can be identified at any time of the year but was not observed on the proposed project site in 2014 or during surveys conducted from 2002–2006. Sapphos Environmental, Inc. performed a visit to a reference population of Davidson’s bush mallow, in which various bush mallow species were easily differentiated from other plant species. No bush mallows of any type were detected on the proposed project site. Therefore, Davidson’s bush mallow habitat is marginal and the species was determined to be absent from the proposed project site. Although 2014 surveys were conducted outside the bloom period for slender mariposa-lily, this species should have been detected during four different surveys conducted from 2002–2006 conducted during the spring bloom. Sapphos Environmental, Inc. performed a visit to a reference population of slender mariposa-lily. The reference population had desiccated seed heads that were apparent, indicating that slender mariposa-lily should have been detected on the proposed project site, if present. The reference population occurred within drier chaparral and was associated with different species than the dominant plants on the proposed project site. Therefore, slender mariposa-lily habitat is marginal and the species was determined to be absent from the proposed project site. Reptiles Coast horned lizard and coastal whiptail are associated with coastal scrub, chaparral, and open cismontane woodland. The woodlands on the proposed project site are not likely habitat given the dense canopy and litter cover, but the parcel uphill has a more open oak canopy, cleared understory, and a mix of chaparral-associated plant species. There is an opening in the woodlands
Single-Family Residence in Studio City Biological Resources Technical Report January 15, 2015 Sapphos Environmental, Inc. W:\PROJECTS\1259\1259-011\Documents\Updated BRTR\Biological Resources Technical Report_2014 12 18.doc 5-8
where coastal scrub/chaparral associated shrub species occur; however, most of the shrub community occurs adjacent to the proposed project site. The shrubs on the proposed project site are generally tall with a contiguous canopy, with most of the better quality habitat for coast horned lizard and coastal whiptail on the adjacent parcels. Therefore, habitat is low quality and only within the open areas around the laurel sumac scrub on the proposed parcel; these species were determined to be absent based on surveys in 2002–2006 and 2014. Birds Cooper’s hawk is a forest-dwelling hawk that lives in urban forested areas of Los Angeles County.84,85,86 Cooper’s hawk, a CDFW watch list species, was observed during surveys in 2014. This hawk has adapted to living in suburban areas and frequently hunts bird feeders for small birds. Although the proposed project would reduce potential nesting and foraging habitat, the overall effect would be minimal. Furthermore, if the proposed project used landscaping that attracted and benefited small birds, then Cooper’s hawk would also benefit from increased prey. Mammals No bats, bat signs, or bat roosts were observed during surveys. However, almost every large oak on the property had holes in the trunk that would be suitable roosts for tree-dwelling bats. Silver-haired bat, hoary bat, and pallid bat are tree-roosting bats that have the potential to occur in areas dominated by oaks. The woodlands on the proposed project site could serve as roosting and foraging habitat, but the lack of nearby water limits the value to these woodlands as roosting habitat. Although these trees may provide roosting habitat, these bats species are not typically faithful to a single roost,87 meaning that the loss of specific trees may not impact a population of tree roosting species because they will switch roost trees from night to night. Although habitat is present, these three species were determined to be absent based on directed surveys in 2014. Common Species The proposed project site serves as habitat for commonly encountered species of plants and animals that can tolerate a high level of urban development. As a result of surveys, Sapphos Environmental, Inc. observed 28 plants, 27 birds, 1 reptile, and 3 mammals (Appendix B). Forty-three (43) percent (12 of 28) of the plants species observed were nonnative species. Four (4) plant species had been previously observed but are currently extirpated, absent because of the drought, or present in very low abundance.

In addition to the species observed, CDFW and nearby residents identified 14 additional species, which were not observed during surveys, which have the potential to be present88,89 (Table 5.1.1-3, Not Observed Common Species with the Potential to Occur).
TABLE 5.1.1-3
NOT OBSERVED COMMON SPECIES WITH THE POTENTIAL TO OCCUR
Species Survey Results Habitat Notes
Amphibians California treefrog (Pseudacris cadaverina)
Absent/ No habitat
The typical habitat for this species is streams within canyons and rocky washes that have permanent pools.90,91
Pacific tree frog (Pseudacris regilla)
Absent/ Habitat present
In 2006, the Pacific tree frog was split into three species, with the local species being the Baja California treefrog (Pseudacris hypochondriaca). The species habitat can occur far from water, including woodlands, chaparral, and urban areas,92 all habitats documented on the proposed project site.
Reptiles
western toad (Anaxyrus boreas halophilus)
Absent/ Habitat present
The habitat for this species habitat includes a variety of areas, including streams, marshes, springs, and woodlands. The habitat on the proposed project site would be habitat for this species.
Birds black-chinned hummingbird (Archilochus alexandri)
Absent/ Habitat present
This is an uncommon species, and it does not associate with woodlands; however, the shrub community on and adjacent to the project site could be habitat for this species.
western scrub-jay (Aphelocoma californica)
Absent/ Habitat present
Presumed present because the presence of oaks could provide their primary food source of acorns.
northern rough-winged swallow (Stelgidopteryx serripennis)
Absent/ No habitat
There is no habitat for northern rough-winged swallow on the proposed project site because this species requires more open areas, especially near flowing or open water.93 The drainage on site is intermittent, and the vegetation cover is too dense for this species; however, it could forage in the skies above.

Species Survey Results Habitat Notes
Birds
Phainopepla (Phainopepla nitens)
Absent/ Habitat present
The oaks provide habitat; however, Phainopepla strongly associate with mistletoe, a primary food source.94 Given that mistletoe presence was observed to be absent-low within the surrounding woodland, this species is likely absent or rarely present.
song sparrow (Melospiza melodia)
Absent/ Habitat present
Potentially present. The lack of understory, especially a lack of understory in the riparian area, reduces the quality of the parcel for song sparrow; however, this species can be associated with houses.95
western screech-owl (Megascops kennicottii) /great horned owl (Bubo virginianus)
Absent/ Habitat present
Both species occurs in suburban to urban environments, but great horned owl is more likely to occur.
Mammals
raccoon (Procyon lotor) Absent/ Habitat present
This species is commonly associates with suburban to urban areas with tree cover.
striped skunk (Mephitis mephitis)
Absent/ Habitat present
This species associates with suburban to urban areas where natural areas border development.
bobcat (Lynx rufus) Absent/ Habitat present
This species is typically found within the foothills of the Santa Monica Mountains but is known to venture into proximal suburban areas.
rabbit species (Lepus curpaeums)
Absent/ Habitat present
The observers did not specify the type of rabbit species that have been observed,96 but cottontails (Sylvilagus sp.) are the only rabbit species within the area of the proposed project site. Cottontails associate with suburban to urban areas.
Virginia opossum (Didelphis virginiana)
Absent/ Habitat present
This species commonly associates with suburban to urban areas with tree cover.

micaceous clay shale or claystone, crumbly where weathered, and thin interbeds of gray to tan semi-friable sandstone.98 As a result of plant community mapping in 2005 using the Holland classification, the proposed project site was characterized as having three plant communities: mule fat scrub, Venturan coastal sage scrub, and coast live oak woodland.99,100 The plant community mapping has been updated using the MCV classification system and field surveys conducted in 2014. As a result, three plant communities were identified: coast live oak woodland , arroyo willow thicket, and laurel sumac scrub (Table 5.1.2-1, Plant Communities on the Proposed Project Site; Figure 5.1.2-1, Plant Communities, Appendix C, Plant Community Survey Data Sheets).

Coast Live Oak Woodland (Quercus agrifolia Woodland Alliance) The small woodlot surrounded by developed houses is dominated by coast live oak woodland. The community is surrounded by existing houses. This community occurs along the hillside, both on the proposed project parcel and on adjacent parcels (Figure 5.1.2-1; Figure 5.1.2-2, Coast Live Oak Woodland Photos). Coast live oak woodland was determined to be present on the proposed project site based on a >50% cover of coast live oak in the tree canopy.101 Coast live oak woodland has a rarity ranking of G5 S4, and is not considered sensitive in California. In addition, the alliance found on the proposed project site is not considered sensitive. The non-drainage portions of the hillside are dominated by mature coast live oak, but the understory is generally lacking. Approximately 5–10 deer were noted within the small parcels and game trails, and hoof punch was noted throughout this plant community; the high concentration of deer may have resulted in a lack of understory, which has been noted in urban areas where deer are over abundant.102 In addition, the adjacent occupied parcel appears to have the understory vegetation cleared, which reduces the value for wildlife and sensitive plant species.

mellifera) were observed within the eastern portion but were less prevalent on the western portion of the woodland on the parcel, but the western portion had some scrub oak (Quercus berberidifolia) in the understory. Other shrubs were present along the plant community boundaries where coast live oak woodland integrates with mulefat thickets, laurel sumac scrub, arroyo willow thickets, and annual brome grassland communities. There is 0.25 acre of coast live oak woodland on the proposed project parcel. The proposed project would convert approximately 0.09 acre of coast live oak woodland to development to accommodate a house and associated landscaping. Permanent impacts could be smaller if alternative project footprints were approved. In addition, although the buffer was analyzed as a permanent impact in this BRTR, it could be considered a temporary impact if landscaping within the project buffer were designed to restore the area to coast live oak woodland. Arroyo Willow Thicket (Salix lasiolepis Shrubland Alliance) The arroyo willow thickets occur on the proposed project site at the end of an existing driveway (Figure 5.1.2-1, Figure 5.1.2-3, Arroyo Willow Thicket Photos). Arroyo willow thickets were determined to be present on the proposed project site based on a >50% relative cover of arroyo willow (Salix lasiolepis) in the tree canopy and no other shrubs with greater relative cover.103 Arroyo willow thicket has a rarity ranking of G4 S4, and is not considered sensitive in California. The willow community occurs in an area that has been previously impacted (i.e., scrapped out and appears to have been anthropogenically flattened) and replanted. Further, a slight man-made berm at the end of the driveway may curtail the natural water flow such that water could pool. This flattened area is the only location that willows are growing within the drainage and the understory is lacking. The understory appears to have been heavily impacted by human foot traffic given a foot trail was observed. Indeed, the nearby residents stated that they regularly used the private parcel to access their adjoining lands.104 The understory species present were generally nonnative species: date palm (Phoenix sp.), Washington fan palm (Washingtonia robusta), oleander (Nerium oleander), horehound (Marrubium vulgare), tree tobacco (Nicotiana glauca), smilo grass (Stipa miliacea), ripgut brome (Bromus diandrus), leafy bent grass (Agrostis pallens), Italian thistle (Carduus pycnocephalus), and cape honeysuckle (Tecoma capensis). Slightly upstream, at the edge of the willow, mulefat (Baccharis salicifolia) is growing along a steep slope (Figure 5.1.2-4, Mulefat at Edge of Arroyo Willow Thicket); given the small size of the mulefat shrub, this congregation was classified as part of the arroyo willow thicket rather than an independent plant community. Water was observed below this plant community, draining into the arroyo willow thicket. Potentially, groundwater is flowing under the mulefat thickets, allowing this riparian species to occur on the steep slopes. Another “perennial spring” occurred at the edge of the existing driveway as recently as 2005;105 however, the area appears to have been naturally or unnaturally filled, such that the hole where the “spring” occurred is no longer visible.

There is 0.10 acre of arroyo willow thickets on the proposed project site. The proposed project would convert approximate 0.006 acre of arroyo willow thicket to development to accommodate the driveway. Laurel Sumac Scrub (Malosma laurina Shrubland Alliance) Laurel sumac scrub was determined to be present on the proposed project site based on a >30% relative cover of laurel sumac (Malosma laurina) in the shrub canopy with co-dominant black sage.106 The laurel sumac scrub occurs on the proposed parcel along a drainage and adjacent to the coast live oak woodland (Figure 5.1.2-1, Figure 5.1.2-5, Laurel Sumac Scrub Photos). The community extends onto adjacent parcels, uphill along the drainage. Openings in the laurel sumac cover allow other coastal sage species to grow, such as black sage (Salvia mellifera), chamise (Adenostoma fasciculatum), horehound, coast sagebrush (Artemisia californica), greenbark ceanothus (Ceanothus spinosus), and deerweed (Acmispon glaber). A portion of this community appears to have been previously disturbed (Figure 5.1.2-6, Disturbed Scrub Photos). The site appears to have been impacted by erosion or humans because the terrain is concave, as if topsoil had been removed. In addition, a concrete wall occurs along the edge of the community at the convergence with the mulefat thicket and arroyo willow thicket. The edges of the clearing are dominated by native shrubs, but the center is mostly ripgut brome with a few low growing shrubs, mostly sticky monkeyflower (Mimulus aurantiacus), olive (Olea europaea), Italian thistle (Carduus pycnocephalus), and horehound and native poison oak. There is 0.14 acre of laurel sumac scrub on the proposed project site. It is expected that less than 0.12 acre would be impacted. Laurel sumac scrub has a rarity ranking of G4 S4, and is not considered sensitive in California. In addition, the alliance found on the proposed project site is not considered sensitive. Developed There is 0.01 acre of developed land, composed of a driveway, within the proposed project site. It is expected that there would be 0.01 acre of impact to the developed area. 5.1.3 Drainages, Wetlands, and Waterways Water on the property enters the site through two locations: a drainage feature in the southeast corner and springs/seeps. The defined bed and bank disappear on the parcel, either becoming surface flow down a game trail or traveling underground. Further, this drainage feature is not riparian because the surrounding plant community is laurel sumac scrub. Water was observed to be flowing out of the ground, and soils were damp at a second location, downhill from the drainage feature (Figure 5.1.3-1, Spring/Seep Location, Figure 5.1.3-2, Spring/Seep Photos). A previous land owner had to construct a perennial spring pursuant to SAA No. 5-365-99 as mitigation for impacts related to the illegal filling of three natural springs on the property.107 The spring/seep observed do not appear to be a constructed spring, and the location of the constructed

spring appears to have been naturally filled. However, the surface flow quickly returns underground. Any surface water from the drainage feature of the spring/seep would then enter a basin (Figure 5.1.2-3), which appears to be an area previously impacted by construction due to the presence of a cut-out cliff and spoils that direct the water away from the developed driveway. Downstream and off the parcels, the terrain is such that water is likely to flow along the edge of the existing driveway. Surface flow was observed at the bottom of the driveway, where water was flowing into a storm drain located at the end of Lankershim Boulevard. Based on existing data on terrain and storm drainages in the area, it is assumed that the storm drain connects to an existing storm drain system at the corner of Lankershim Boulevard and Vineland Avenue, which then drains into the Los Angeles River (Figure 5.1.3-3, Storm Drains Downhill of the Proposed Project Site). Federal Wetlands The NWI map for this project does not include any federal wetlands.108 Based on the wetland delineation performed on site in 2014, the proposed project does not have a wetland subject to USACOE jurisdiction because of a lack of wetland vegetation, soils, or hydrology. Previously, the USACOE surveyed the site and determined that the riparian area on the parcel is not subject to USACOE jurisdiction.109,110,111 The results of the 2014 wetland delineation found:
1) Vegetation: Facultative wetland and facultative plants were present in the Arroyo Willow Thicket and Mulefat Scrub communities. The tree stratum at both sampling locations was dominated by arroyo willow, a facultative wetland species, but the shrub and herb stratums were dominated by cape honeysuckle (Tecoma capensis), laurel sumac, leafy bent grass, and smilo grass, which are all facultative upland species. The vegetation at the sampling location at the center of the riparian area was positive for wetland vegetation, based on the Prevalence Index. Therefore, wetland vegetation was determined to be present (Appendix D, USACOE Wetland Determination Data Form-Arid West Region).
2) Soils: Given the presence of roots and compact soils, soil pits could be dug only to a depth of 17 and 13 inches. Soils within both soils pits did not have redox, color indicating wetland soils, or any of the other hydric soil indicators (Appendix D). Therefore, the soils were determined to be non-wetland.
3) Hydrology: No primary or secondary wetland hydrology features were observed (Appendix D). Therefore, the hydrology was classified as non-wetland.

State Wetlands No blue-line features were present on the site, and the USGS maps do not indicate the presence of streams. However, the presence of the riparian habitat and connection to the Los Angeles River via covered storm drains means that the proposed project is subject to the jurisdiction of CDFW and the Regional Water Quality Control Board (RWQCB). Based on CDFW’s definition of a wetland, the drainage feature and basin on the proposed project site is subject to CDFW jurisdiction. Indeed, SAAs had been previously issued by CDFW and the parcels had been mitigated for prior, unauthorized impacts from a previous land owner.112,113,114 CDFW typically asserts jurisdiction to the top of a stream bank, or the outer limits of riparian vegetation, whichever is greater. Therefore, mapping of the CDFW jurisdictional area followed the limit of the riparian vegetation except for downstream portions of the basin where vegetation was absent but a man-made bank was present (Figure 5.1.1-4, Figure 5.1.2-1); based on this, the limits of the CDFW jurisdiction included the springs/seeps but not where surface flow from the non-riparian drainage feature would be entering the riparian area and basin. All of the areas meeting criteria for CDFW jurisdiction also met the criteria for RWQCB jurisdiction. 5.1.4 Fish or Wildlife Movement Corridors or Nursery Sites Sapphos Environmental, Inc. observed worn game trails on the proposed project site that generally was parallel with the crest of the hill (Figure 5.1.4-1, Approximate Location of Observed Game Trails). In addition, 5–10 deer were observed moving on and adjacent to the proposed project parcel, especially higher up the slope on an occupied parcel where a wider man-made trail was created from a slope stabilization feature. Wildlife cameras took 249 sets of photos/videos on the proposed project site, but wildlife was detected only on 138 photos/videos (55%); the remainder of the photos without wildlife was not used because it was not possible to determine if wind-blown plants or fast-moving wildlife were the reason the camera activated. Sapphos Environmental, Inc. observed mule deer in 106 photo/video sets, a gray squirrel on 31 photo/video sets, and an unidentified snake in one (1) photo/video set (Figure 5.1.4-2, Wildlife Camera Photos). During the October 9, 2014 survey, biologists observed that deer were more frequently using trails upslope on undeveloped portions of occupied parcels. Biologists also noted coyote running up the driveway of the adjacent houses on Lankershim Boulevard, but the understory on the proposed project site is conducive for foraging only. Mule deer have a home range of 0.8 to 2 square miles, and coyotes have a home range of 4 to 8 square miles, meaning that both species could use the proposed project parcel for foraging only and be bedding down/denning in larger areas of contiguous habitat within several miles of the proposed project site. Camera 1 observed only squirrels (i.e., no deer); however, the numbers of deer photographs were similar among Camera 2–5, with 28, 20, 34, and 24 photos, respectively. However, despite similar number of photos, many of the photos from Camera 2 and 3 were of foraging deer; indeed, deer was observed at Camera 2 on 43 percent (6 of 14) and at Camera 3 on 36 percent (5 of 14) of the observation days. In contrast, Camera 4 photographed deer on 85 percent (12 of 14) and Camera 5 on 81 percent (9 of 11) of the observation days.

Based on the data, local deer movement in autumn seems to occur more regularly on the eastern and upper portions of the proposed project parcel. Impacts would occur in the lower and western portions of the parcel, close to Cameras 1 and 2, which had less frequent deer observations. Areas with more frequent deer observations would be preserved. Indeed, Cameras 4 and 5 were placed near this trail. Most likely, this slope stabilization feature serves as a primary movement route. Wildlife corridors are areas in between large tracts of habitat, in which wildlife pass through in order to reach higher quality habitat. Given the terrain, local movement would generally occur from an east to west/north-west direction. The parcel has limited value as a corridor because highly developed areas, such as Universal Studios and housing developments, occur north and west (Figure 5.1.4-3, Potential Corridors of Undeveloped Areas within Developed Areas). Wildlife moving westerly would cross Willowcrest Avenue to reach a woodlot surrounded by houses, but the movement farther west/north across Vineland Avenue and Sunshine Terrance is impeded by development. However, there are less developed lots to the south of the project, which could allow for wildlife movement near the ridge crest that Mulholland Drive bisects. Wildlife moving along these areas may enter the parcel from the east, but movement would end near Vineland Avenue and Sunshine Terrance. Two local game trails (including one cutoff) are expected to be impacted as a result of the proposed project parcel; however, the deer in the area persist despite development and are utilizing man-made trails. No migratory fish routes or nurseries would be affected as a result of the proposed project given the lack of permanent water connecting to waterways. Birds have a potential to nest on site; however, no rookeries are present. 5.1.5 Plans and Policies City of Los Angeles General Plan After further review of the City of Los Angeles General Plan, it was determined that one policy may potentially conflict with the proposed project.115 The proposed project would not be expected to conflict with Section 12, Policy 1. The proposed project is in conflict with Section 6, Policy 1 because sensitive wildlife has the potential to occur based on the presence of habitat and riparian habitat. Protected Tree Ordinance The Protected Tree Ordinance established which species are protected and the regulations enacted for those tree species within the boundaries of the City of Los Angeles. An oak tree survey was performed by a certified arborist, which documented two oak species, coast live oak and scrub oak, with a trunk diameter of 2 inches or greater;116 both species were observed on October 9 and 23, 2014. However, only the coast live oak is classified as “Protected Trees” under the oak tree ordinance because the ordinance does not extend to scrub oaks. Although the ordinance specifically calls out Quercus dumosa scrub oak, a rare plant, Q. dumosa is a term that is often applied to 6+ scrub oak species within the Q. dumosa complex, whose taxonomy has been

periodically realigned.117 According to the oak tree report, there are 11 coast live oaks (Quercus agrifolia), eight (8) of which were rated D by the certified arborist, meaning that the trees are in various states of decline as a result of disease, pests, or stress and could be considered hazardous.118 Based on the tree condition specified by the certified arborist, these eight (8) trees may be permitted for removal, contingent on approval by the Board of Public Works, because the ordinance allows for removal of protected trees that show “a substantial decline from a condition of normal health and vigor, and restoration.” A maximum of three (3) protected oaks and one (1) scrub oak may be impacted as a result of the proposed project. In addition, the driplines of four (4) healthy protected oaks occur within the proposed project buffer; activity within the driplines are considered impacts under the City of Los Angeles ordinance because construction could damage the root system. Mulholland Scenic Parkway Specific Plan
Sapphos Environmental, Inc. reviewed USGS topographical maps of the proposed project site. Based on these maps, there were no streams located on the project parcel; rather, the riparian plants are present because an erosional drainage can provide enough water for these plants.119 Therefore, the proposed project is not in conflict with the stream provision of the MSPSP based on the MSPSP’s definition of streams. There are Quercus agrifolia (i.e., coast live oak) present on the proposed project site, which has a potential to conflict with the oak tree provision of the MSPSP. 5.1.6 HCPs and NCCPs The proposed project site is not located within the boundaries of any Habitat Conservation Plan (HCP) or Natural Community Conservation Plan (NCCP).120 This was confirmed by USFWS and CDFW.121,122 There are three HCPs/NCCPs in Los Angeles County: the West Mojave HCP and Desert Renewable Energy Conservation Plan NCCP/HCP located in the Mojave Desert and the Palos Verdes Peninsula NCCP/HCP. 5.2 CEQA ANALYSIS The State CEQA Guidelines recommend the consideration of the following six questions when addressing the potential for significant impacts to biological resources: (a) Have a substantial adverse effect, either directly or through habitat modification, on any
species identified as a candidate, sensitive, or special status species in local or regional

There is no occupied habitat or potential habitat for the five listed state or federally threatened and endangered species; therefore, there are no impacts to listed species. There was 1 fully protect or sensitive species observed and habitat for seven other species. The proposed project would result the loss of less than 0.25 acre of habitat for: Davidson’s bush mallow, slender mariposa-lily, coast horned lizard, coastal whiptail, Cooper’s hawk, silver-haired bat, hoary bat, and pallid bat (Table 5.2-1, Habitat Impacts; Figure 5.2-1, Maximum Impact Area). Despite the fact that the majority of coastal scrub (i.e., Laurel Sumac Scrub) on the proposed project parcel would be lost, only 12 percent of the overall habitat would be lost when considering that the overall plant community extends onto adjacent developed parcels (Figure 5.1.1-2). However, the habitat is generally small or of low quality (i.e., some habitat conditions are not fully met), and none of the fully protected and sensitive species were observed. All of the large oak trees on the project site have the potential for roosting bats given that they have holes in the tree trucks. Although these trees may provide roosting habitat, these bats species are not typically faithful to a single roost,123 meaning that the loss of specific trees may not impact a population of tree roosting species because they will switch roost trees from night to night. Furthermore, no bats, bat signs, or bat roosts were observed during surveys. Therefore, impacts are not expected to be significant. However, out of an abundance of caution, one mitigation measure has been proposed to ensure that any potential impacts would be reduced to below the level of significance.

Note: * Indicates community that would be the primary habitat on the proposed project site
More than half of the 0.5-acre parcel would be untouched and remain as habitat for sensitive and common species. The proposed project is not expected to result in extirpation of these species, and these species would be expected to be observed even after construction is complete. None of the common species are afforded special protection, except for nests of breeding native birds pursuant to the MBTA. Construction of the proposed project would result in the loss of up to 0.2 acre of habitat; however, the species observed by biologists and local citizens are species that have persisted in the area despite a high-level of development and regular human disturbance (e.g., noise, pets, lawn care, traffic, etc.). Indeed, some of these species can benefit from development because of a potential for increased food sources, such as California towhee and song sparrow, which are birds that frequent bird feeders. Furthermore, human-tolerant species such as deer, raccoon, skunks, coyote, opossums, owls, hawks, small birds, and frogs and toads are known to survive in urban environments and can often become pests.124,125126,127 Therefore, impacts are not

expected to be significant, but mitigation measures have been recommended to ensure that any potential impacts to nesting birds, roosting bats, and sensitive plants would be reduced to below the level of significance. Recommended Mitigation Measures BIO-1: Prior to initial ground-disturbance and vegetation removal activities for all project-related
construction activities, a qualified biologist shall conduct a pre-construction sweep of the project site for special-status wildlife. This includes at least one nocturnal survey for roosting bats and one diurnal survey for reptiles and birds.
BIO-2: Prior to initial ground-disturbance and vegetation removal activities for all project-related
construction activities, a qualified biologist shall conduct a breeding bird nest survey for raptors and owls (January 1–August 31) and small birds (February 1–August 31). Alternatively, clearing may occur in the non-breeding season (September 1–December 31) without a nesting bird survey.
(b) Have a substantial adverse effect on any riparian habitat or other sensitive natural
community identified in local or regional plans, policies, regulations; or by the California Department of Fish and Game or the U.S. Fish and Wildlife Service?
There are no state sensitive plant communities on the proposed project site.128 The proposed project would result in impacts for up to 0.226 acre of commonly occurring plant communities. Individual oak trees will be addressed further under the CEQA question related to ordinances. Although the buffer around the house was analyzed as a permanent impact in this BRTR, it could be considered a temporary impact if landscaping within the project buffer were designed to restore the area to coast live oak woodland. The springs/seeps present on the parcel would not be impacted as a result of the proposed project. Based on MCV, the riparian habitat was classified as arroyo willow thicket, which is not state sensitive. Given that this is community is riparian habitat, mitigation, or avoidance may be required for these plant communities should direct impacts occur. There is 0.1 acre of riparian habitat on the proposed project parcel and another 0.05 acre located on the adjacent property. A maximum of 0.006 acre of riparian habitat may be impacted as a result of construction of a driveway, which amounts to <6 percent of the total riparian area within the parcel and on the adjacent parcel (Figure 5.1.1-2). An area of disturbance occurs adjacent to the riparian areas, and ripgut brome extends into the existing springs/seeps; this area could be restored as a potential mitigation site (Figure 5.2-2, Potential Riparian Mitigation Site). The proposed house and patios would not be located within the inflow drainage, but soil stabilization may be needed along the inflow and riparian edges so that erosion would not affect the drainage. The driveway would have to be designed such that additional water would not contribute to soil erosion and additional

sediments into the riparian area. Alternatively, redesigning the driveway could avoid the riparian area altogether. A SAA between the property owner and the CDFW may be required to ensure that there is no net loss of habitat, thus reducing impacts to below the thresholds for significance.129,130 The final SAA shall specify any and all mitigation requirements, including performance standards, such as: 1) the provision of restoration of the riparian area, 2) a conservation easement through a portion of the proposed project site, 3) the placement a wildlife guzzler, or 4) the purchase of mitigation bank property. Therefore, impacts to biological resources in relation to the riparian habitat would be reduced to below the level of significance by the incorporation of the specified mitigation measures in the SAA. One mitigation measure has been recommended to reflect the need for a SAA to reduce impacts so that there is a “no net loss” of riparian habitat. Recommended Mitigation Measure BIO-3: Prior to the issuance of a building permit, the project applicant shall demonstrate:
a. A Streambed Alteration Agreement has been obtained from the California Department of Fish and Wildlife. All required avoidance and minimization measures, as finalized through consultations with the California Department of Fish and Game, shall be implemented during construction. Restoration and mitigation of riparian areas could be mitigated on site, especially adjacent to the springs/seeps where Annual Brome Grasslands encroach upon the springs/seeps. Alternatively, mitigation through a local mitigation bank may be acceptable.
b. Construction shall avoid the existing riparian vegetation except for the maximum of 0.01 acre needed to place the driveway. Construction crews shall avoid entering the riparian area outside of the project impact area unless a qualified biologist is present. Riparian areas within the buffer shall be avoided, but any temporary impacts will be restored post-construction with native riparian shrubs.
c. The driveway design shall be engineered to divert run-off away from the riparian area to avoid erosion.
d. Construction crew will be required to construct temporary erosion controls so that soil is not added to the existing drainage.
e. Landscaping post-construction shall be used to prevent further erosion into the existing riparian area. Potential soil erosion can also be controlled with appropriate structures, such as retaining walls.
f. In the event that construction activities take place during the rainy season, silt fence shall be put in place, near drainages, to minimize erosion.
g. Pollution resulting from servicing and refueling of equipment shall be prevented to the maximum extent feasible by disposing of waste properly and selecting service

and refueling areas away from wet areas and surface water. All residues, waste oil, and other materials shall be removed from the proposed project property and disposed of properly.
(c) Have a substantial adverse effect on federally protected wetlands as defined by Section 404
of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means?
The proposed project would not be expected to result in impacts to biological resources in relation to federally protected wetlands or as defined by Section 404 of the Clean Water Act through direct removal, filling, hydrological interruption, or other means. Therefore, this drainage is not subject to the jurisdiction of the USACOE pursuant to Section 404 of the Clean Water Act. Impacts to wetlands as defined by CDFW had been disclosed above within the CEQA question that addresses state-designated riparian habitat. Furthermore, implementation of the recommended mitigation measure BIO-3 would reduce impacts of state-designated wetlands to below the level of significance. (d) Interfere substantially with the movement of any native resident or migratory fish or wildlife
species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites?
The proposed project would not be expected to substantially interfere with the movement of any native resident or migratory fish or wildlife species because the majority of the parcel would not be subject to construction. The proposed project would not be expected to result in impacts to biological resources in relation to impeding the use of native wildlife nursery sites. Two game trails would be affected by the development of the house; a third game trial across the proposed project property would be slightly altered but not eliminated because the wildlife would likely access the trail via accessing the driveway. There are a large number of game trails on the parcel and on the adjacent parcels; removal of two trails may shift the local game movement but not completely eliminate the movement because most of the wildlife movement was observed upslope on a soil stabilization structure and on the eastern portions of the parcel. The location of the proposed house is within an existing potential wildlife corridor that is approximately 90 meters wide (Figure 5.2-3, Potential Corridor Widths After Impacts). The location of the proposed house has been situated so that the potential wildlife corridor shall remain at least 49 meters wide (i.e., the size of the existing potential wildlife corridor would be reduced by a maximum of 45). The 49 meters of potential wildlife corridor that would remain after the development of the house is comparable in size or larger than nearby existing potential wildlife corridors; for example, the undeveloped area to the east is 10–30 meters wide, given the proximity between existing houses (Figure 5.2-1). Although the size of the potential corridor is reduced, the connectivity is unchanged. Furthermore, the parcel and surrounding parcels may be a poor potential corridor because wildlife would have to travel back upslope given that the east-west movement of wildlife likely would not continue beyond Ventura Boulevard due to a high-level of development to the north and northwest. Wildlife that traversed the parcel from east to west would either have to turn around or cross developed neighborhood to the southwest in order to return to move westward along the Santa Monica Mountains. Note that undeveloped slopes located to the south near the crest of the ridge may function as a better potential wildlife movement corridor and, therefore, some wildlife

movement may occur on the proposed project site because of the proximity to these larger, undeveloped areas. The proposed project site does not act as a migratory corridor for fish. The species of bats potentially present on the proposed project site are not site faithful and their roost periodically move; therefore, the loss of up to three (3) oak trees is not expected to significantly potential impact bat roosts because of the number of oak trees on project parcel and the surrounding parcels. Furthermore, no bats, bat signs, or bat roosts were observed during surveys. The riparian habitat present at the proposed project site is of low value to wildlife because there is no connection to other riparian areas, including streams or bodies of water or open space. The area is more likely being used by local wildlife. However, the proposed project would not be expected to impact any potential wildlife corridors because 1) less than half of the existing potential corridor habitat would be reduced; 2) the remaining corridor would still be larger than the potential corridors to the east and west of the proposed project site; 3) two game trails may be impacts, but there are a large number of trails on site, including ones that currently bypass the proposed project; 4) any wildlife that wanted to move between Griffith Park and the western Santa Monica Mountains would likely be moving higher upslope where larger patches of habitat exist; and 5) east-west movement of wildlife across the proposed project site would either end at Ventura Boulevard or backtrack to traverse housing in order to get to larger tracts uphill. Therefore, there would be no expected impacts to biological resources related to movement of any migratory fish or wildlife species or with an established wildlife corridor, and no mitigation is required. Implementation of recommended mitigation measure BIO-1 would ensure protection of any roosting bats and reduce any potential impacts to below the level of significance. (e) Conflict with any local policies or ordinances protecting biological resources, such as a tree
preservation policy or ordinance? The proposed project would be expected to result in potentially significant impacts to biological resources in relation to conflicts with any local policies or ordinances protecting biological resources, thus requiring the consideration of mitigation measures. The City of Los Angeles Protected Tree Ordinance131 and the MSPSP132 both have protection on oak trees. Of the 11 coast live oak, a maximum of 7 could be impacted as a result of project implementation (Figure 5.2-4, Oaks within Maximum Footprint). However, a maximum of three (3) may need to be removed; therefore, four (4) trees that have dripline within the buffer around the proposed house could be avoided during construction. The arborist rated these trees as a C– (1 tree) or D (2 trees) because their overall condition was below average/poor.133 To ensure compliance with the MSPSP and the City of Los Angeles oak tree ordinance, prior written approval from the Director of the City Planning Department and the City of Los Angeles Board of Public Works would need to be obtained. In addition, the trees that would be removed may need to be replaced on site at a ratio of 4:1 to remain in compliance with the MSPSP and City of Los Angeles conditions for the removal of oak trees.134 131 City of Los Angeles Ordinance No. 177404 132 City of Los Angeles, Planning Department, 13 May 1992.

The MSPSP oak tree provision allows for limited tree removal at the discretion of the Director. The MSPSP states:
No oak tree (Quercus agrifolia, Q. lobata, Q. virginiana) shall be removed, cut down or moved without the prior written approval of the Director. Therefore, the Director may approve the removal, cutting down or moving of an oak tree after making the following findings: a. The removal, cutting down or moving of an oak tree will not result in an undesirable, irreversible soil erosion through diversion or increased flow of surface waters. b. The oak tree is not located with reference to other trees or monuments in such a way as to acquire a distinctive significance at said location.
Therefore, the proposed project must demonstrate that soil erosion will not increase because of water flowing over the ground and that the trees are not distinctively significant. Based on the proposed site plan and site surveys:
1) The removal of trees would not contribute to increased erosion via surface flow
because a house will be placed on top of the tree locations, such that water flowing from uphill would have the energy reduced by the house and plants that will be planted around the house.
2) There are no monuments, not within an easily visible location, and the trees are in poor health, meaning that the removal of 27 percent (3 of 11 coast live oak) of the trees on the proposed project site is not expected to result in a loss of a distinctive significance of the location.
Therefore, the proposed project would reduce potential impacts to oak trees to below the level of significance by complying with local ordinances and regulations. Recommended Mitigation Measures BIO-4: Prior to the issuance of a building permit, the project applicant shall obtain approval from
the Director of the City Planning Department indicating that the removal of up to three (3) oak trees would not result in undesirable, irreversible soil erosion or the distinctive significance, if any were present.
BIO-5: Prior to the issuance of a building permit, the project applicant shall apply for and obtain a
Tree Removal Permit from the City of Los Angeles Department of Public Works. The project applicant shall consult with the Board of Public Works and the Bureau of Street Services to determine the value of the trees and determine the required mitigation, if any.
BIO-6: Prior to construction, a certified arborist shall place “No Work” buffers around coast live
oak trees that are not required to be moved in order to implement the proposed project. The minimum buffer size shall be the extent of the individual trees dripline. Only foot traffic is allowed within the “No Work” buffer. Activities prohibited within the “No Work” buffer include equipment storage, grading, vegetation removal, equipment movement, trimming, or the placement of fill. Equipment refueling shall not occur adjacent to the buffer.
(f) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community
Conservation Plan, or other approved local, regional, or state habitat conservation plan?

The proposed project is not located within or near the boundaries of any HCP or NCCP; therefore the proposed project would not conflict with the provisions of any adopted HCP or NCCP. Given the lack of an HCP/NCCP, there will be no further analysis of alternative on HCPs/NCCPs in the EIR.

PREVIOUS SURVEYS The following species were documented on previous surveys but were absent from the 2014 surveys. Fuchsia-flowered gooseberry (Ribes speciosum) is a shrub and its absence during 2014 surveys suggests that this species is extirpated from the proposed project site. The perennial chilicothe (Marah macrocarpus) and nonnative grasses previously documented are either extirpated or the current drought has resulted in these species temporarily being absent.
