This BRA summarizes the effects on biological resources within the project study area (PSA) for use in the environmental document, and presents technical information upon which later decisions regarding project design may be developed. 1.1 PROJECT LOCATION El Cerrito is located in Contra Costa County, in the northern San Francisco Bay Area, approximately 13.5 miles north of Oakland (Figures 1 and Contra Costa County is bordered by the counties of Alameda to the south, Solano to the north, and San Joaquin to the east. El Cerrito is bordered by Richmond to the north and west, Albany to the south, and Wildcat Canyon Regional Park and Kensington to the east. El Cerrito is approximately 5 miles from the campus of the University of California, Berkeley, and is located approximately one-half mile east of San Francisco Bay. 1.2 PROJECT DESCRIPTION The Elm Street condominium project proposes 13 new condominiums and the rehabilitation and relocation of the existing single-family detached house on the site (Figure The existing 1,116-square-foot house contains two bedrooms. The proposed condominium units will contain a combination of one- and three-bedroom units totaling 14,147 square feet, with 3 one- bedroom units (approximately 869 square feet per unit) and 10 three-bedroom units (approximately 1,154 square feet per unit). The project proposes a residential density of 33 units per acre. Parking will be provided in a gated parking garage located below the units and includes one parking space designed to comply with the requirements of the Americans with Disabilities Act. The project proposes 14 new parking spaces and is requesting an exception to the City parking requirements, which requires 19 spaces. The proposed parking exception is based on the proximity of the project site to the El Cerrito del Norte BART station, several bus lines, and nearby commercial uses. 1.3 PROJECT SETTING The project site is a fairly level, rectangular 0.42-acre lot located at 1715 Elm Street. There is currently a fence running across the front of the property to restrict access to the site. The site slopes from a high point along the Elm Street frontage to the western boundary, representing a 3 percent slope across the property. It currently includes a vacant two-story house built in 1897, a detached garage, a well house, and a shed. There are several persimmon trees and one miniature lemon tree on-site. The site has fallen into disrepair and is now overgrown with weeds and unkempt landscaping. An open, rock-lined drainage ditch runs east–west across the site along the southern edge of the property approximately 20 feet from the house. The ditch is approximately 4 feet deep and continues westerly onto the adjacent property in an open box culvert. The ditch conveys stormwater runoff from upstream properties to the east. The project site is primarily surrounded by residential neighborhoods. Elm Street and residential properties are to the east, residential properties and Hill Street to the north, residential ---PAGE BREAK--- CHAPTER 1 INTRODUCTION Biological Resources Assessment 1715 Elm Street Condominiums 2 properties and Liberty Street to the west, and a day care and Blake Street are located to the south (Figure Windrush School, a private K–8 school, is approximately 700 feet to the northeast, while San Pablo Avenue, which is a major commercial corridor, and a Safeway store are a few blocks to the west. The El Cerrito del Norte BART station is approximately one- quarter mile to the northwest. ---PAGE BREAK--- S a n S a n F r a n c i s c o F r a n c i s c o C o u n t y C o u n t y S o l a n o S o l a n o C o u n t y C o u n t y A l a m e d a A l a m e d a C o u n t y C o u n t y M a r i n M a r i n C o u n t y C o u n t y C o n t r a C o s t a C o n t r a C o s t a C o u n t y C o u n t y S o n o m a S o n o m a C o u n t y C o u n t y N a p a N a p a C o u n t y C o u n t y S a n M a t e o S a n M a t e o C o u n t y C o u n t y S a n t a C l a r a S a n t a C l a r a C o u n t y C o u n t y Oakland San Jose Concord Antioch San Rafael--Novato Santa Rosa Vallejo Fairfield Napa Livermore Petaluma Sonoma Sonoma Half Moon Bay Half Moon Bay Dixon Dixon Fairfield Southwest Fairfield Southwest Yountville Yountville Sacramento River T:\_GIS\CONTRA_COSTA_COUNTY\MXDS\EL_CERRITTO\ELM_STREET\FIG 1 REGIONAL LOCATION.MXD - 11/12/2009 @ 11:01:54 AM 3.5 0 3.5 MILES Project Location Figure 1 Project Regional Location Source: ESRI Streetmap USA P a c i f i c O c e a n San Pablo Bay San Francisco Bay ---PAGE BREAK--- CHAPTER 1 INTRODUCTION Biological Resources Assessment 1715 Elm Street Condominiums 4 This page intentionally left blank. ---PAGE BREAK--- Source: Microsoft Bing Maps, 2013 T:\_GIS\CONTRA_COSTA_COUNTY\MXDS\EL_CERRITTO\ELM_STREET\FIG 2 PROJECT LOCATION.MXD - 2/7/2013 @ 5:09:36 PM 500 0 500 FEET Project Location Figure 2 Project Location ---PAGE BREAK--- CHAPTER 1 INTRODUCTION Biological Resources Assessment 1715 Elm Street Condominiums 6 This page intentionally left blank. ---PAGE BREAK--- Sources: City of El Cerrito, LCA Architects FEET 0 10 20 Figure 3 Site Plan with Conceptual Streetscape and Buffer Yard Planting T:\_CS\Work\El Cerrito, City of\1715 Elm Street 29-0152\figures EXISTING HOUSE PROPOSED CONDOMINIUMS ---PAGE BREAK--- CHAPTER 1 INTRODUCTION Biological Resources Assessment 1715 Elm Street Condominiums 8 This page intentionally left blank. ---PAGE BREAK--- CHAPTER 2 REGULATORY SETTING 1715 Elm Street Condominiums Biological Resources Assessment 9 This section identifies the environmental review and consultation requirements as well as permits and approvals that must be obtained from local, state, and federal agencies before implementation of the proposed project. 2.1 FEDERAL 2.1.1 ENDANGERED SPECIES ACT The Endangered Species Act of 1973 (ESA), as amended, provides protective measures for federally listed threatened and endangered species, including their habitats, from unlawful take (16 United States Code (USC) Sections 1531–1544). The ESA defines “take” to mean “harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or to attempt to engage in any such conduct.” Title 50, Part 222, of the Code of Federal Regulations (50 CFR Section 222) further defines “harm” to include “an act which actually kills or injures fish or wildlife. Such an act may include significant habitat modification or degradation where it actually kills or injures fish or wildlife by significantly impairing essential behavioral patterns including feeding, spawning, rearing, migrating, feeding, or sheltering.” ESA Section 7(a)(1) requires federal agencies to utilize their authority to further the conservation of listed species. ESA Section 7(a)(2) requires consultation with the US Fish and Wildlife Service (USFWS) and/or the National Marine Fisheries Service (NMFS) if a federal agency undertakes, funds, permits, or authorizes (termed the federal nexus) any action that may affect endangered or threatened species, or designated critical habitat. For projects that may result in the incidental “take” of threatened or endangered species, or critical habitat, and that lack a federal nexus, a Section 10(a)(1)(b) incidental take permit can be obtained from the USFWS and/or the NMFS. 2.1.2 CLEAN WATER ACT The basis of the Clean Water Act (CWA) was established in 1948; however, it was referred to as the Federal Water Pollution Control Act. The act was reorganized and expanded in 1972 (33 USC Section 1251), and at this time the Clean Water Act became the act’s commonly used name. The basis of the CWA is the regulation of pollutant discharges into waters of the United States (WoUS), as well as the establishment of surface water quality standards. 2.1.2.1 Section 404 CWA Section 404 (33 USC Section 1344) established the program to regulate the discharge of dredged or fill material into WoUS, including wetlands. Under this regulation, certain activities proposed within WoUS require the obtainment of a permit prior to initiation. These activities include, but are not limited to, placement of fill for the purposes of development, water resource projects dams and levees), infrastructure development highways and bridges), and mining operations. The primary objective of this program is to ensure that the discharge of dredge or fill material is not permitted if a practicable alternative to the proposed activities exists that results in less impact to WoUS, or the proposed activity would result in significant adverse impacts to WoUS. To comply with these objectives, a permittee must document the measures taken to avoid and minimize impacts to WoUS, and provide compensatory mitigation for any unavoidable impacts. ---PAGE BREAK--- CHAPTER 2 REGULATORY SETTING 1715 Elm Street Condominiums Biological Resources Assessment 10 The US Environmental Protection Agency (EPA) and the USFWS are assigned roles and responsibilities in the administration of this program; however, the US Army Corps of Engineers (USACE) is the lead agency in the administration of day-to-day activities, including issuance of permits. The agencies will typically assert jurisdiction over the following waters: traditional navigable waters (TNW); wetlands adjacent to TNWs; relatively permanent waters (RPW) that are non-navigable tributaries to TNWs, and have relatively permanent flow or seasonally continuous flow (typically three months); and wetlands that directly abut RPWs. Case-by- case investigations are usually conducted by the agencies to ascertain their jurisdiction over waters that are non-navigable tributaries and do not contain relatively permanent or seasonal flow, wetlands adjacent to the aforementioned features, and wetlands adjacent to but not directly abutting RPWs (USACE 2007). Jurisdiction is not generally asserted over swales or erosional features gullies or small washes characterized by low volume/short duration flow events), or ditches constructed wholly within and draining only uplands that do not have relatively permanent flows. The extent of jurisdiction within WoUS, which lack adjacent wetlands, is determined by the ordinary high water mark (OHWM). The OHWM is defined in 33 CFR Section 328.3(e) as the “line on the shore established by the fluctuations of water and indicated by physical characteristics such as clear, natural line impressed on the bank, shelving, changes in the character of soil, destruction of terrestrial vegetation, the presence of litter and debris, or other appropriate means that consider the characteristics of the surrounding areas.” Wetlands are further defined under 33 CFR Section 328.3 and 40 CFR Section 230.3 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” and typically include “swamps, marshes, bogs, and similar areas.” The USACE (1987) Corps of Engineers Wetland Delineation Manual (1987 Manual) sets forth a standardized methodology for delineating the extent of wetlands under federal jurisdiction. The 1987 Manual outlines three parameters that all wetlands, under normal circumstances, must contain positive indicators for to be considered jurisdictional. These parameters include wetland hydrology, hydrophytic vegetation, and hydric soils (USACE 1987). In 2006, the USACE issued a series of Regional Supplements to address regional differences that are important to the functioning and identification of wetlands. The supplements present “wetland indicators, delineation guidance, and other information” that is specific to the region. The USACE requires that wetland delineations submitted after June 5, 2007, be conducted in accordance with both the 1987 Manual and the applicable supplement. 2.1.2.2 Section 401 Under CWA Section 401 (33 USC Section 1341), federal agencies are not authorized to issue a permit and/or license for any activity that may result in discharges to WoUS, unless a state or tribe where the discharge originates either grants or waives CWA Section 401 certification. CWA Section 401 provides states or tribes with the ability to grant, grant with conditions, deny, or waive certification. Granting certification, with or without conditions, allows the federal permit/license to be issued and remain consistent with any conditions set forth in the CWA Section 401 certification. Denial of the certification prohibits the issuance of the federal license or permit, and waiver allows the permit/license to be issued without state or tribal comment. Decisions made by states or tribes are based on the proposed project’s compliance with EPA water quality standards as well as applicable effluent limitation guidelines, new source performance standards, toxic pollutant restrictions, and any other appropriate requirements of ---PAGE BREAK--- CHAPTER 2 REGULATORY SETTING 1715 Elm Street Condominiums Biological Resources Assessment 11 state or tribal law. In California, the State Water Resources Control Board is the primary regulatory authority for CWA Section 401 requirements (additional details below). 2.1.3 MIGRATORY BIRD TREATY ACT Migratory birds are protected under the Migratory Bird Treaty Act of 1918 (16 USC Sections 703–711). The Migratory Bird Treaty Act makes it unlawful to take, possess, buy, sell, purchase, or barter any migratory bird listed in 50 CFR Section 10, including feathers or other parts, nests, eggs, or products, except as allowed by implementing regulations (50 CFR Section 21). The majority of birds found in the project vicinity would be protected under the act. 2.1.3.1 Bald and Golden Eagle Protection Act The bald eagle (Haliaeetus leucocephalus) and golden eagle (Aquila are federally protected under the Bald and Golden Eagle Protection Act (16 USC Sections 668– 668c). Under the act, it is illegal to take, possess, sell, purchase, barter, offer to sell or purchase or barter, transport, export, or import at any time or in any manner a bald or golden eagle, alive or dead; or any part, nest, or egg of these eagles unless authorized by the Secretary of the Interior. Violations are subject to fines and/or imprisonment for up to one year. Active nest sites are also protected from disturbance during the breeding season. 2.2 STATE 2.2.1 CALIFORNIA ENDANGERED SPECIES ACT Under the California Endangered Species Act (CESA), the California Department of Fish and Wildlife (CDFW) has the responsibility for maintaining a list of endangered and threatened species (California Fish and Game Code [FGC] Section 2070). The CDFW also maintains a list of “candidate species,” which are species formally noticed as being under review for potential addition to the list of endangered or threatened species, and a list of “species of special concern,” which serve as a species “watch lists.” Pursuant to the requirements of the CESA, an agency reviewing a proposed project within its jurisdiction must determine whether any state-listed endangered or threatened species may be present, and determine whether the proposed project will have a potentially significant impact on such species. In addition, the CDFW encourages informal consultation on any proposed project that may impact a candidate species. Project-related impacts to species on the CESA endangered or threatened list would be considered significant. State-listed species are fully protected under the mandates of the CESA. “Take” of protected species incidental to otherwise lawful management activities may be authorized under FGC Section 206.591. Authorization from the CDFW would be in the form of an incidental take permit. 2.2.2 CALIFORNIA FISH AND GAME CODE 2.2.2.1 Streambed Alteration Agreement State and local public agencies are subject to FGC Section 1602, which governs construction activities that will substantially divert or obstruct the natural flow or substantially change the bed, channel, or bank of any river, stream, or lake designated as waters of the state by the CDFW. Under FGC Section 1602, a discretionary Streambed Alteration Agreement must be ---PAGE BREAK--- CHAPTER 2 REGULATORY SETTING 1715 Elm Street Condominiums Biological Resources Assessment 12 issued by the CDFW to the project proponent prior to the initiation of construction activities within lands under CDFW jurisdiction. As a general rule, this requirement applies to any work undertaken within the 100-year floodplain of a stream or river containing fish or wildlife resources. 2.2.2.2 Native Plant Protection Act The Native Plant Protection Act (FGC Sections 1900–1913) prohibits the taking, possessing, or sale within the state of any plants with a state designation of rare, threatened, or endangered (as defined by the CDFW). An exception in the act allows landowners, under specified circumstances, to take listed plant species, provided that the owners first notify the CDFW and give that state agency at least 10 days to retrieve the plants before they are plowed under or otherwise destroyed (FGC Section 1913). Project impacts to these species are not considered significant unless the species are known to have a high potential to occur within the area of disturbance associated with construction of the proposed project. 2.2.2.3 Birds of Prey Under FGC Section 3503.5, it is unlawful to take, possess, or destroy any birds in the orders Falconiformes or Strigiformes (birds of prey), or to take, possess, or destroy the nest or eggs of any such bird except as otherwise provided by this code or any regulation adopted pursuant thereto. 2.2.2.4 Fully Protected Species California statutes also afford “fully protected” status to a number of specifically identified birds, mammals, reptiles, and amphibians. These species cannot be “taken,” even with an incidental take permit. FGC Section 3505 makes it unlawful to “take” “any aigrette or egret, osprey, bird of paradise, goura, numidi, or any part of such a bird.” FGC Section 3511 protects from “take” the following fully protected birds: American peregrine falcon (Falco peregrinus anatum); brown pelican (Pelecanus occidentalis); California black rail (Laterallus jamaicensis coturniculus); California clapper rail (Rallus longirostris obsoletus); California condor (Gymnogyps californianus); California least tern (Sterna albifrons browni); golden eagle; greater sandhill crane (Grus canadensis tabida); light-footed clapper rail (Rallus longirostris levipes); southern bald eagle (Haliaeetus leucocephalus leucocephalus); trumpeter swan (Cygnus buccinator); white- tailed kite (Elanus leucurus); and Yuma clapper rail (Rallus longirostris yumanensis). FGC Section 4700 identifies the following fully protected mammals that cannot be “taken”: Morro Bay kangaroo rat (Dipodomys heermanni morroensis); bighorn sheep (Ovis canadensis), except Nelson bighorn sheep (subspecies Ovis canadensis nelsoni); Guadalupe fur seal (Arctocephalus townsendi); ring-tailed cat (genus Bassariscus); Pacific right whale (Eubalaena sieboldi); salt-marsh harvest mouse (Reithrodontomys raviventris); southern sea otter lutris nereis); and wolverine (Gulo gulo). FGC Section 5050 protects from “take” the following fully protected reptiles and amphibians: blunt-nosed leopard lizard (Crotaphytus wislizenii silus); San Francisco garter snake (Thamnophis sirtalis tetrataenia); Santa Cruz long-toed salamander macrodactylum croceum); limestone salamander (Hydromantes brunus); and black toad (Bufo boreas exsul). ---PAGE BREAK--- CHAPTER 2 REGULATORY SETTING 1715 Elm Street Condominiums Biological Resources Assessment 13 FGC Section 5515 also identifies certain fully protected fish that cannot lawfully be “taken” even with an incidental take permit: Colorado River squawfish lucius); thicktail chub (Gila crassicauda); Mohave chub (Gila mohavensis); Lost River sucker (Catostomus luxatus); Modoc sucker (Catostomus microps); shortnose sucker (Chasmistes brevirostris); humpback sucker (Xyrauchen texanus); Owens River pupfish (Cyprinoden radiosus); unarmored threespine stickleback (Gasterosteus aculeatus williamsoni); and rough sculpin (Cottus asperrimus). 2.2.3 CALIFORNIA WETLANDS AND OTHER WATER POLICIES The State Water Resources Control Board and its various departments do not authorize or approve projects that fill or otherwise harm or destroy coastal, estuarine, or inland wetlands. Exceptions may be granted if all of the following conditions are met: The project is water-dependent. No other feasible alternative is available. The public trust is not adversely affected. Adequate compensation is proposed as part of the project. 2.2.3.1 Porter-Cologne Water Quality Control Act The Porter-Cologne Water Quality Control Act of 1966 (California Water Code Section 13000 et seq.; CCR Title 23, Chapter 3, Subchapter 15) is the primary state regulation that addresses water quality. The requirements of the act are implemented by the at the state level and by the Regional Water Quality Control Board at the local level. The carries out planning, permitting, and enforcement activities related to water quality in California. The act provides for waste discharge requirements and a permitting system for discharges to land or water. Certification is required by the for activities that can affect water quality. 2.2.3.2 Clean Water Act, Section 401 Water Quality Certificaton CWA Section 401 (33 USC Section 1341) requires that any applicant for a federal license or permit, which may result in a pollutant discharge to WoUS, obtain a certification that the discharge will comply with EPA water quality standards. The state or tribal agency responsible for issuance of the Section 401 certification may also require compliance with additional effluent limitations and water quality standards set forth in state/tribal laws. In California, the is the primary regulatory authority for CWA Section 401 requirements. The San Francisco Bay is responsible for enforcing water quality criteria and protecting water resources in the project area. In addition, the is responsible for controlling discharges to surface waters of the state by issuing waste discharge requirements (WDR), or commonly by issuing conditional waivers to WDRs. The requires that a project proponent obtain a CWA Section 401 water quality certification for CWA Section 404 permits issued by the USACE. A request for water quality certification (including WDRs) by the and an application for a General Permit for Storm Water Discharges Associated with Construction Activities are prepared and submitted following completion of the California Environmental Quality Act (CEQA) environmental document and submittal of the wetland delineation to the USACE. ---PAGE BREAK--- CHAPTER 2 REGULATORY SETTING 1715 Elm Street Condominiums Biological Resources Assessment 14 2.2.3.3 Delegated Permit Authority California has been delegated permit authority for the National Pollutant Discharge Elimination System permit program including stormwater permits for all areas except tribal lands. Issuance of CWA Section 404 dredge and fill permits remains the responsibility of the USACE; however, the state actively uses its CWA Section 401 certification authority to ensure CWA Section 404 permits are in compliance with state water quality standards. 2.2.3.4 State Definition of Covered Waters Under California state law, “waters of the state” means “any surface water or groundwater, including saline waters, within the boundaries of the state.” Therefore, water quality laws apply to both surface water and groundwater. After the US Supreme Court decision in Solid Waste Agency of Northern Cook County v. US Army Corps of Engineers, the Office of Chief Counsel of the released a legal memorandum confirming the state’s jurisdiction over isolated wetlands. The memorandum stated that under the California Porter-Cologne Water Quality Control Act (Porter-Cologne), discharges to wetlands and other waters of the state are subject to state regulation, and this includes isolated wetlands. In general, the State Water Resources Control Board regulates discharges to isolated waters in much the same way as it does for WoUS, using Porter-Cologne rather than Clean Water Act authority. 2.3 NONGOVERNMENTAL AGENCY 2.3.1 CALIFORNIA NATIVE PLANT SOCIETY The California Native Plant Society (CNPS) is a nongovernmental agency that classifies native plant species according to current population distribution and threat level, in regard to extinction. These data are utilized by the CNPS to create and maintain a list of native California plants that have low numbers, limited distribution, or are otherwise threatened with extinction. This information is published in the Inventory of Rare and Endangered Plants of California (CNPS 2012). Potential impacts to populations of CNPS-listed plants receive consideration under CEQA review. The following identifies the definitions of the CNPS listings: List 1A: Plants believed to be extinct List 1B: Plants that are rare, threatened, or endangered in California and elsewhere List 2: Plants that are rare, threatened, or endangered in California, but are more numerous elsewhere All of the plant species on Lists 1 and 2 meet the requirements of the Native Plant Protection Act Section 1901, Chapter 10, or FGC Section 2062 and Section 2067 and are eligible for state listing. Plants appearing on List 1 or 2 are considered to meet the criteria of CEQA Section 15380, and effects on these species are considered “significant.” Plants on List 3 (plants about which we need more information) and/or List 4 (plants of limited distribution), as defined by the CNPS, are not currently protected under state or federal law. Therefore, no detailed descriptions or impact analysis was performed on species with these classifications. ---PAGE BREAK--- CHAPTER 2 REGULATORY SETTING 1715 Elm Street Condominiums Biological Resources Assessment 15 2.4 LOCAL 2.4.1 EL CERRITO MUNICIPAL CODE 2.4.1.1 Chapter 19.12 – Creek Protection Overlay District Chapter 19.12 of the El Cerrito Municipal Code affords protective measures to natural watercourses identified in the –CP Creek Protection (CP) overlay district. The purpose of the CP overlay district is to delineate creeks and major drainages and ensure that development or other activities in these sensitive areas achieves the following goals: Preserves, enhances, and restores natural drainage ways as parts of the storm drainage system, minimizing any alterations or structures within the natural stream channel and streambed. Preserves riparian vegetation and protects wildlife habitat and wildlife corridors along natural drainage ways. Protect lands adjacent to riparian areas as public or private permanent open space through dedication or easements. Protects property owners and the public from erosion and flooding. Increases access to creeks for maintenance purposes and for potential public access to creek-side amenities. Ensures that projects are consistent with City Council adopted guidelines and resolutions for creek restoration and improvement, including designated creeks as natural corridors with habitat enhancement. Furthers the Joint Watershed Goals Statement of restoring creeks by removing culverts, underground pipes, and obstructions to fish and animal migration, and daylighting creeks where they can be enjoyed by people and wildlife. ---PAGE BREAK--- CHAPTER 3 STUDY METHODS 1715 Elm Street Condominiums Biological Resources Assessment 16 This section describes the survey methods used to collect data on biological resources on and in the vicinity of the project site. 3.1 STUDIES REQUIRED Pedestrian surveys were conducted within the PSA to assess the biological resources that may be impacted as part of the proposed project. A habitat assessment was performed to identify the habitat present within the PSA and in the vicinity, along with an informal evaluation of potentially jurisdictional waters. A biologist reviewed the proposed project description, performed literature reviews and database searches, and conducted biological surveys to obtain information regarding habitat quality and the presence of sensitive plant and wildlife species within the PSA. 3.1.1 LITERATURE REVIEW A list of special-status species and habitats that have the potential to occur within the PSA or in the vicinity was prepared using information provided by the USFWS Sacramento office’s Species Lists (2012a), the USFWS Critical Habitat Portal (2012b), the CDFW’s California Natural Diversity Database 2012a), and the CNPS’s Inventory of Rare and Endangered Plants of California (2012). A search of the USFWS Sacramento office Species List database was performed for the Richmond, California, USGS 7.5-minute quadrangle to identify special-status species under their jurisdiction that may be affected by the proposed project. In addition, a query of the USFWS Critical Habitat Portal was conducted to identify any designated critical habitat on or in the vicinity of the PSA. No critical habitat was identified. The provided a list of known occurrences for special-status species within a 1-mile and 5-mile radius of the PSA. Lastly, the CNPS database was queried to identify special-status plant species with the potential to occur within the Richmond, California, USGS quadrangle. Please see Appendix A for the raw data returned from the database queries. 3.1.2 HABITAT ASSESSMENT A reconnaissance-level survey was conducted by PMC biologists Summer Pardo on September 21, 2012. The purpose of this survey was to identify habitat types within the PSA, including potentially jurisdictional waters and sensitive natural communities. The field investigation included a general inspection of the PSA. Data collected during the survey was used to generate a habitat layer for the PSA using ESRI’s ArcGIS mapping program.

In addition, the impact analysis utilized data collected from the literature review, reconnaissance-level survey, and habitat mapping. Impacts to specific biological resources are identified, and appropriate avoidance, minimization, compensation, and/or mitigation measures are discussed further in Chapter 5. ---PAGE BREAK--- CHAPTER 4 BIOLOGICAL SETTING 1715 Elm Street Condominiums Biological Resources Assessment 18 This chapter describes the region in which the project will occur, including a description of the existing biological conditions. 4.1 EXISTING LAND USES The site survey on September 21, 2012, revealed that urban residential land uses dominate the proposed project site and adjacent lands. The site is dominated by residential uses, with one surface water feature on the southern portion of the parcel (Table 1, Figure The site contains one residential structure, along with a storage shed, carport, and pump house. The vegetation on-site is characterized by ruderal herbaceous species, with scattered orchard trees. In addition, one U-shaped surface water feature traverses the property from east to west. This feature is characterized by cobble reinforced sidewalls and bed, and is dominated by watercress (Nasturtium officinale). TABLE 1: EXISTING LAND USE CLASSIFICATIONS Land Use Acreage Urban 0.41 Surface Water 0.01 Total 0.42 4.2 REGIONAL SPECIES AND HABITATS OF CONCERN 4.2.1 WETLANDS AND OTHER WATERS OF THE US Jurisdictional WoUS and isolated wetlands provide a variety of functions for plants and wildlife. Wetlands and other water features provide habitat, foraging, cover, migration, and movement corridors for both special-status and common species. In addition to habitat functions, these features provide physical conveyance of surface water flows capable of handling large stormwater events. Large storms can produce extreme flows that cause bank cutting and sedimentation of open waters and streams. Jurisdictional waters can slow these flows and lessen the effects of these large storm events, protecting habitat and other resources. The informal evaluation of potentially jurisdictional waters identified one surface water feature within the PSA, which is a daylighted portion of Baxter Creek. A formal delineation has not been conducted or verified to date. ---PAGE BREAK--- Elm Street Blake Street Liberty Street Source: Bing Maps, 2012; PMC, 2012 T:\_GIS\CONTRA_COSTA_COUNTY\MXDS\EL_CERRITTO\ELM_STREET\FIG HABITAT.MXD - 10/26/2012 @ 1:12:37 PM 25 0 25 FEET Figure 4 Existing Land Use Map Legend Project Site Habitat Surface Water Urban ---PAGE BREAK--- CHAPTER 4 BIOLOGICAL SETTING 1715 Elm Street Condominiums Biological Resources Assessment 20 This page intentionally left blank. ---PAGE BREAK--- CHAPTER 4 BIOLOGICAL SETTING 1715 Elm Street Condominiums Biological Resources Assessment 21 4.2.2 SPECIAL-STATUS SPECIES Candidate, sensitive, or special-status species are commonly characterized as species that are at potential risk or actual risk to their persistence in a given area or across their native habitat. These species have been identified and assigned a status ranking by governmental agencies such as the CDFW, the USFWS, and private organizations such as the CNPS. The degree to which a species is at risk of extinction is the determining factor in the assignment of a status ranking. Some common threats to a species’ or a population’s persistence include habitat loss, degradation, and fragmentation, as well as human conflict and intrusion. For the purposes of this BRA, special-status species are defined by the following codes: Listed, proposed, or candidates for listing under the ESA (50 CFR Section 17.11 – listed; 61 Federal Register Section 7591, February 28, 1996, candidates) Listed or proposed for listing under the CESA (FGC 1992 Section 2050 et seq.; 14 California Code of Regulations (CCR) Section 670.1 et seq.) Designated as Species of Special Concern by the CDFW Designated as Fully Protected by the CDFW (FGC Sections 3511, 4700, 5050, 5515) Species that meet the definition of rare or endangered under CEQA (14 CCR Section 15380), including CNPS List 1 and 2 Several special-status species were identified by the database queries (Table however, the urban land uses on and adjacent to the proposed project site do not provide suitable habitat for any of the special-status plant species listed as occurring in the area. In addition, several wildlife species were identified. The majority of the species with the potential to occur in the project vicinity are associated with coastal habitats salt marshes, mangroves, brackish/estuarine waters). These habitats do not occur on-site; therefore, no impacts to special-status species associated with coastal habitats will occur. Further discussions regarding potential impacts to special-status species are provided in Subsection 5.2. ---PAGE BREAK--- ---PAGE BREAK--- CHAPTER 4 BIOLOGICAL SETTING 1715 Elm Street Condominiums Biological Resources Assessment 23 TABLE 2: SPECIAL-STATUS SPECIES IN THE PROJECT VICINITY Common Name Scientific Name Federal Status State Status CNPS Rare Plant Rank General Habitat Characteristics Potential to Be Affected by the Project Plants Pallid manzanita Arctostaphylos pallida T E 1B.1 Siliceous shale, sandy or gravelly soil.

Potential effects to species are based on the pre-application subdivision exhibit; current project description; likelihood of each species to occur within the PSA; and each species’ biological growth, reproduction, feeding, resting, and cover requirements as appropriate. Each species is discussed, including results of surveys for the species, designated critical habitat for the species within the PSA (if applicable), avoidance and minimization measures proposed to avoid or reduce project-related impacts to the species, expected or potential project-related effects to the species, and cumulative effects to the species when considered with other proposed, completed, or reasonably foreseeable projects in the project vicinity. Project-related effects to plant and wildlife species can be direct, indirect, permanent, temporary, and cumulative. Direct impacts are those caused by the proposed project and occur at the time of project construction or implementation. Indirect effects are those that are caused by the proposed project and are reasonably certain to occur, but occur later in time. 5.1 STANDARDS OF SIGNIFICANCE The impact analysis provided below is based on the following CEQA Guidelines Appendix G thresholds of significance: 1) Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special-status species in local or regional plans, policies or regulations, or by the CDFW or USFWS. 2) Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, or regulations or by the CDFW or USFWS. 3) Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the CWA (including but not limited to marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means. 4) 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. 5) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance. 6) Conflict with the provisions of an adopted habitat conservation plan, natural community conservation plan, or other approved local, regional, or state habitat conservation plan. ---PAGE BREAK--- CHAPTER 5 DISCUSSION OF IMPACTS AND MITIGATION Biological Resources Assessment 1715 Elm Street Condominiums 32 7) Reduce the number or restrict the range of an endangered, rare, or threatened plant or animal species or biotic community, thereby causing the species or community to drop below self-sustaining levels. 5.2 METHODOLOGY The impact assessment below discusses impacts from implementation of project activities. The impact assessment was based on the project description, information described in the project and biological setting, and the standards of significance described above. In addition, the impact analysis is organized by the significance criteria noted above: special-status plant and wildlife species, sensitive vegetation communities, federally protected wetlands, wildlife movement corridors, and compliance with local plans and policies, or existing habitat conservation plans. Each impact category includes a description of the specific potential impacts as well as avoidance, minimization, and mitigation measures that can potentially reduce and mitigate potentially significant impacts. 5.3 IMPACTS TO CANDIDATE, SENSITIVE, OR SPECIAL-STATUS SPECIES (STANDARD OF SIGNIFICANCE 1) Impact BIO-1 Implementation of project-related activities could result in substantial adverse effects, either directly or through habitat modifications, to special-status species, which would be considered a potentially significant impact. Several special-status species were identified by the database queries; however, the urban land uses on and adjacent to the proposed project site do not provide suitable habitat for any of the special-status plant species listed as occurring in the area. In addition, several wildlife species were identified. The majority of the species with the potential to occur in the project vicinity are associated with coastal habitats salt marshes, mangroves, brackish/estuarine waters). These habitats do not occur on-site; therefore, no impacts to special-status species associated with coastal habitats will occur. A few species associated with streams/creeks were identified as having the potential to occur in the project vicinity. The on-site surface water was historically a natural creek that was channelized for stormwater conveyance. A geographic information system (GIS) data layer was obtained from Contra Costa County (2007) that depicts the location and extent of creeks in El Cerrito. An analysis was conducted using the creek GIS layer and aerial photointerpretation of existing land uses to determine the extent of Baxter Creek that has been undergrounded. This analysis determined that Baxter Creek is approximately 9,550 feet in length, approximately 7,750 linear feet have been undergrounded, and 1,800 linear feet remain daylighted (Figure The on-site surface water represents approximately 115 linear feet of the daylighted segments. The special-status fish species associated with streams/creeks, which have the potential to occur in the project vicinity, are anadramous. Although Baxter Creek eventually drains into San Francisco Bay, approximately 1.25 miles of the creek is undergrounded between the project site and the bay. The extent of creek that is underground before reaching the property precludes the migration of any special-status fish species into the on-site surface water. In addition, the lack of natural connections to suitable habitat for the special-status amphibian ---PAGE BREAK--- CHAPTER 5 DISCUSSION OF IMPACTS AND MITIGATION 1715 Elm Street Condominiums Biological Resources Assessment 33 and reptile species associated with streams/creeks in the project vicinity, and the unsuitable habitat conditions within the on-site surface water, eliminate the potential for these species to occur on-site. Therefore, no impact to special-status species will occur as a result of the proposed project. The proposed project does, however, have the potential to impact migratory birds, raptors, and bats. Trees on and adjacent to the project site may provide suitable nesting habitat for birds protected under the Migratory Bird Treaty Act, as well Sections 3503.5 and 3800–3806 of the Fish and Game Code. In addition, the abandoned structures on-site have the potential to provide suitable nesting habitat for protected birds, as well as roosting habitat for bats. The demotion of the abandoned structures and removal of trees during construction activities could result in noise, dust, human disturbance, and other direct/indirect impacts to nesting birds and roosting bats on or in the vicinity of the project site. Potential nest abandonment and mortality to eggs and chicks would be considered a potentially significant impact to protected bird species; however, implementation of mitigation measures MM-BIO-1 through MM-BIO-3 will reduce those impacts to a less than significant level. In addition, mortality of roosting bat species during construction would be considered a potentially significant impact; however, implementation of mitigation measure MM-BIO-4 will reduce those impacts to a less than significant level. 5.3.1 AVOIDANCE AND MINIMIZATION MEASURES MM-BIO-1 Survey for Migratory Birds. If clearing and/or construction activities will occur during the migratory bird nesting season (April 15–August 15), preconstruction surveys for nesting migratory birds shall be conducted by a qualified biologist, up to 14 days before initiation of construction activities. The qualified biologist shall survey the construction zone and a 250- foot radius surrounding the construction zone to determine whether the activities taking place have the potential to disturb or otherwise harm nesting birds. If active nest(s) are identified during the preconstruction survey, a qualified biologist shall monitor the nest to determine when the young have fledged. monitoring reports, documenting nest status, will be submitted to the City Planning Department until the nest(s) is deemed inactive. The biological monitor shall have the authority to cease construction if there is any sign of distress to a raptor or migratory bird. Reference to this requirement and the Migratory Bird Treaty Act shall be included in the construction specifications. MM-BIO-2 Survey for Active Raptor Nests. If construction activities will occur during nesting season for raptors (January 15–August 15), all suitable raptor nesting habitat within 0.5 mile of the impacted area will be surveyed for active raptor nests before construction activity commences. If an active raptor nest is located within 0.5 mile of the construction site, a no-activity buffer will be erected around the nest while it is active to protect the nesting raptors. This buffer distance may be ---PAGE BREAK--- CHAPTER 5 DISCUSSION OF IMPACTS AND MITIGATION Biological Resources Assessment 1715 Elm Street Condominiums 34 amended to account for nests that are not within the line of sight of the construction activity. MM-BIO-3 Conduct Surveys for Bird Nests in Structures. If demolition of abandoned structures will take place during of the migratory bird nesting season (April 15–August 15), then, a survey for nesting migratory birds swallows, phoebes) will precede demolition. If bird nests are discovered in the structure, the building will not be removed until the nest(s) become inactive. MM-BIO-4 Conduct Surveys of Potential Bat Roosts. Demolition of abandoned structures will be preceded by a survey for bat presence. Structures being used by bats will not be removed until it has been determined that bats are no longer using the site or until demolition can be carried out without harming any bats. 5.4 IMPACTS TO RIPARIAN HABITAT OR SENSITIVE NATURAL COMMUNITIES (STANDARD OF SIGNIFICANCE 2) Sensitive habitats include those that are of special concern to resource agencies and those that are protected under CEQA, Section 1600 of the Fish and Game Code, and Section 404 of the Clean Water Act (CWA). The project proponent is proposing to underground the on-site surface water for the purposes of constructing new condominiums. This U-shaped feature is characterized by cobble reinforced sidewalls and bed, and is dominated by watercress (Nasturtium officinale). No riparian habitat is associated with this feature; therefore, this impact would be less than significant. ---PAGE BREAK--- Tributary of Baxter Creek Baxter Creek Source: Bing Maps, 2012; Contra Costa County, 2012; PMC, 2012 T:\_GIS\CONTRA_COSTA_COUNTY\MXDS\EL_CERRITTO\ELM_STREET\FIG CREEK.MXD - 10/26/2012 @ 1:11:32 PM 500 0 500 FEET Figure 5 Creek Map Legend Project Site Daylighted Underground ---PAGE BREAK--- CHAPTER 5 DISCUSSION OF IMPACTS AND MITIGATION Biological Resources Assessment 1715 Elm Street Condominiums 36 This page intentionally left blank. ---PAGE BREAK--- CHAPTER 5 DISCUSSION OF IMPACTS AND MITIGATION 1715 Elm Street Condominiums Biological Resources Assessment 37 5.5 IMPACTS TO FEDERALLY PROTECTED WETLANDS (STANDARD OF SIGNIFICANCE 3) Impact BIO-2 Implementation of project-related activities could result in the disturbance, degradation, and/or removal of federally protected wetlands, which would be considered a potentially significant impact. To date, a jurisdictional determination for the project has not been verified by any state or federal agencies. However, the on-site surface water is presumed to be jurisdictional to the USACE, Regional Water Quality Control Board, and CDFW. Authorization to place fill within the on-site jurisdictional feature may be required by the USACE, through the CWA Section 404 permitting process prior to project implementation. If a CWA Section 404 permit were to be required, a CWA Section 401 permit would be also required from the If it is determined that the on-site jurisdictional feature qualifies as waters of the state, and would be affected by the proposed project, the applicant would be required to obtain authorizations from the and the CDFW to fill/disturb these features prior to project implementation. Furthermore, construction-related impacts to water quality would be mitigated through the implementation of best management practices (BMPs). Implementation of mitigation measure MM-BIO-5 would reduce impacts to waters of the state and waters of the United States to a less than significant level. 5.5.1 AVOIDANCE AND MINIMIZATION MEASURES MM-BIO-5 Mitigate for Loss of Waters of the United States. If the US Army Corps of Engineers identifies that the feature is jurisdictional, the project applicant shall ensure that the project will result in no net loss of waters of the United States by providing mitigation through impact avoidance, impact minimization, and/or compensatory mitigation for the impact, as determined in the CWA Section 404/401 permits and/or 1602 Streambed Alteration Agreement. Compensatory mitigation may consist of obtaining credits from a mitigation bank; or making a payment to an in-lieu fee program that will conduct wetland, stream, or other aquatic resource restoration, creation, enhancement, or preservation activities. Evidence of compliance with this mitigation measure shall be provided prior to construction and grading activities for the proposed project. If the USACE verifies that the feature is not jurisdictional, no mitigation will be required. 5.6 IMPACTS TO THE MOVEMENT OF NATIVE RESIDENT OR MIGRATORY FISH OR WILDLIFE SPECIES OR WITHIN ESTABLISHED MIGRATORY CORRIDORS (STANDARD OF SIGNIFICANCE 4) Implementation of the proposed project would not interfere substantially with the movement of native resident or migratory fish or wildlife species. No established migratory routes are identified on or adjacent to the project site. Additionally, the on-site drainage feature has no natural connections to perennial features utilized by anadromous fish species. Due to the highly urbanized land uses in the project vicinity, it is unlikely that any significant aquatic or ---PAGE BREAK--- CHAPTER 5 DISCUSSION OF IMPACTS AND MITIGATION Biological Resources Assessment 1715 Elm Street Condominiums 38 wildlife corridors exist in the project vicinity. Therefore, no impact will occur, and no mitigation is proposed. 5.7 CONFLICT WITH LOCAL POLICIES AND ORDINANCES (STANDARD OF SIGNIFICANCE 5) Impact BIO-8 Implementation of project-related activities may conflict with El Cerrito Municipal Code Chapter 19.12, which would be considered a potentially significant impact. The proposed project will result in the bridging/undergrounding of the on-site surface water for the purposes of constructing new condominiums. Therefore, the proposed activities would conflict with local policies or ordinances protecting biological resources. The on-site surface water provides marginal habitat value for wildlife that may include utilization by local birds and mammals, as well as by feral/domesticated pets. As a result, bridging/undergrounding the on-site surface water would result in less than significant impacts to biological resources, and no mitigation is proposed. 5.8 CONFLICT WITH CONSERVATION PLANS (STANDARD OF SIGNIFICANCE 6) The proposed project would not conflict with the provisions of an adopted habitat conservation plan, natural community conservation plan, or other approved local, regional, or state habitat conservation plan. There are no adopted habitat conservation plans that overlap the PSA; therefore, the proposed project would not conflict with such plans, and no impact is anticipated. No avoidance and minimization measures are proposed. 5.9 SPECIAL-STATUS SPECIES POPULATION IMPACTS (STANDARD OF SIGNIFICANCE 7) Implementation of project-related activities would not reduce the number or restrict the range of an endangered, rare, or threatened plant or animal species or biotic community, thereby causing the species or community to drop below self-sustaining levels. As such, there would be no impact. Mitigation measures MM-BIO-1 through MM-BIO-9 will ensure that the proposed project does not reduce sensitive plant, wildlife, habitat, and/or other biological resources below self- sustaining levels. As such, there would be a less than significant impact, and no additional avoidance and minimization measures are proposed. ---PAGE BREAK--- CHAPTER 6 REFERENCES 1715 Elm Street Condominiums Biological Resources Assessment 39 Busby, P.
