The purpose of this letter is to provide information on the current condition of the biological resources within the project boundary and an assessment of potential impacts and mitigation of the proposed project in accordance with federal, state, and local laws and regulations. Introduction The proposed project would construct a private residence located at 4246 Hillside Drive in the city of Carlsbad, California (Figure 1). The project boundary is located in an unsectioned portion of the Agua Hedionda Land Grant in Range 4 West, Township 12 South, of the San Luis Rey Quadrangle U.S. Geological Survey topographic map, and consists of .a 0.26-acre undeveloped lot surrounded by development (Figures 2 and 3). The project boundary is also located within the boundaries of the final Multiple Habitat Conservation Plan (MHCP), which is a multi-jurisdictional habitat conservation plan that was prepared for seven north San Diego County jurisdictions: Oceanside, Carlsbad, Encinitas, San Marcos, Vista, Solana Beach, and Escondido (San Diego Association of Governments [SANDAG] 2003). More specifically, the project site falls within the City of Carlsbad's MHCP Subarea Plan, which is the City of Carlsbad's Habitat Management Plan (HMP). The project boundary is not within or adjacent to a HMP Preserve Area (Figure 4). Methods RECON biologist Cailin Lyons conducted a general biological survey of the project boundary on July 27, 2018. Prior to conducting surveys, species occurrence records in the California Natural Diversity Database (CNDDB) from within two miles were reviewed. Vegetation communities were mapped on al-inch-equals- 25-foot aerial photograph flown in 2018. Vegetation community classifications follow Oberbauer et al. (2008), which are based on Holland's 1986 Preliminary Descriptions of the Terrestrial Natural Communities of California. All plant species observed on-site were also noted, and plants that could not be identified in the field were identified later in the laboratory using taxonomic keys. The survey also included a directed search for sensitive plants and wildlife that would have been apparent during the time of the survey. The project boundary was assessed for potential sensitive biological and aquatic resources, including sensitive vegetation communities, wetlands/waters, plants, and wildlife. Assessments for the potential occurrence of sensitive species are based upon known ranges, habitat preferences for the species, and species occurrence records from the CNDDB (State of California 2018). 1927 Fifth Avenue, San Diego, CA 92101 I 619.308.9333 I reconenvironmental.com SAN DIEGO I CENTRAL COAST I BERKELEY I TUCSON * Project Location REC O N M:IJOBSS\9228\common_gis\fig1 .mxd 8/1/2018 Imm FIGURE 1 Regional Location * Project Location REC ON M:\JOBS5\9228\common_gis\fig2.mxd 8/1/2018 Imm 0 Feet 2,000 0 FIGURE 2 Project Location on USGS Map 0 Feet D Pr oject Boundary REC ON M:\JOBS5\9228\common_gis\fig3.mxd 8/1/2018 Imm FIGURE 3 Project Location on Aerial Photograph c:::J Project Boundary [I] Local Facility Management Zone 1 Carlsbad FPA / Core #4 RECON ~ Existing Hardline -Pre-existing Natural Open Space Preserve ~ Proposed Standards Area FIGURE 4 Project in Relation to City of Carlsbad HMP Area M:\JOBS5\9228\common_gis\fig4.mxd 8/1/2018 Imm Mr. Jesse Smith Page 6 August 2, 2018 Survey Results Physical Characteristics The project boundary occurs in an undeveloped lot in a neighborhood in Carlsbad, California. The undeveloped lot shows evidence of recent grading and vegetation removal within a portion of the site. The project site is bounded by private residences to the north and south, with a landscaped slope and residence to the north, and Hillside Drive to the south (see Figure 3). The project boundary is further surrounded by a mosaic of residential development and undeveloped lots. One soil type, Corralitos loamy sand (5 to 9 percent slopes), is mapped within the project boundary. Corralitos loamy sand consists of somewhat excessively drained, very deep loamy sands. This soil type is formed in alluvium derived from marine sandstone and is typically located in narrow valleys and on small alluvial fans (U.S. Department of Agriculture 1973). Biological Resources The project boundary contains two land cover types: disturbed land and urban/developed (Table 1; Figure 5; Photographs 1 and 2). The urban/developed consists of an unvegetated area that was recently graded prior to the biological survey. The disturbed land consists primarily of bare ground with ripgut grass (Bromus diandrus), castor bean (Ricinus communis), chrysanthemum (Chrysanthemum sp.), and ice plant (Ca,pobrotus edulis). Some scattered native shrubs, such as lemonade berry (Rhus integrifolia), laurel sumac (Malosma laurina), and coastal California buckwheat (Eriogonum fasciculatum var. fasciculatum) occur intermixed with the non-native vegetation but generally provide low cover and provide low habitat value due to the isolated nature of the site. Based on aerial photography and street imagery, the Urban/Developed land appears to have had similar vegetation composition as the Disturbed Land prior to the recent grading activities. Table 1 Existing Land Cover Types within the Project Boundary Land Cover Tvoes Acreage Disturbed Land 0.13 Urban/Develooed 0.13 TOTAL 0.26 A total of 13 plant species were identified within the project boundary. Of these plant species, four are considered native and nine are considered non-native. A complete list of the plant species identified within the project site is shown in Table 2. In addition, one wildlife species, honeybee (Apis mellifera) was identified within the project site at the time of the survey. Sensitive Biological Resources The presence of sensitive biological resources and their potential for occurrence were evaluated within the project boundary. No sensitive biological resources, including sensitive plants or wildlife, were identified at the time of the survey. Furthermore, no sensitive plants are anticipated to occur due to high levels of disturbance within the project boundary (e.g., visible soil disturbance and prevalence of non-native species). One sensitive wildlife species, California horned lark (Eremophila alpestris actia), has moderate potential to nest within the disturbed habitat within the project site. Additionally, there is potential for nesting of migratory birds to occur within the project boundary. The potential for sensitive plants and wildlife within the project boundary are discussed further in Attachments 1 and 2.

Impacts to disturbed land and urban/developed are not considered significant, as these land cover types are not considered sensitive biological resources. Although these land cover types are not considered sensitive, mitigation is required by the City of Carlsbad's HMP for impacts to disturbed land. The urban/developed land that was previously graded will also require mitigation, as it was likely comprised of disturbed land prior to grading. No direct impacts to sensitive plant are expected to occur, as no sensitive plants were identified within the project boundary and none are expected to occur. There is a potential for direct and indirect impacts to migratory or nesting birds, including California horned lark, within the project boundary should vegetation removal and/or grading occur during the general bird breeding season (February 15-September 15). Mitigation for potentially significant direct impacts to nesting and migratory birds are required under the California Fish and Game Code 3503 (California Department of Fish and Wildlife 1991).

All impacts to sensitive biological resources should be avoided to the maximum extent feasible and minimized when possible. Mitigation for potential impacts to land cover types and nesting birds, including California horned lark, are discussed in further detail below. Sensitive Biological Resources Vegetation Communities/Land Cover Types. Prior to the issuance of any permits for land disturbance or grading, the project applicant shall pay the per acre in lieu mitigation fee to the City of Carlsbad for impacts to 0.13 acre of disturbed land (including the 0.13 acre of urban/developed that was previously graded). Nesting Birds. To conform to the California Fish and Game Code, no impacts shall occur to any nesting birds or their eggs, chicks, or nests during the breeding season (i.e., February 15-September 15). If vegetation removal and/or grading are proposed during the bird breeding season, a qualified biologist shall conduct a survey for active nests within the project boundary and an addition 500-foot survey buffer within three days of construction. If nests of sensitive birds or migratory birds are located, they will be fenced with a protective buffer of at least 500 feet from active nests of listed species, and 300 feet from other sensitive bird species (City of Carlsbad 2008). All construction activity will be prohibited within this area. Conclusion The aforementioned mitigation measures would mitigate potential impacts to vegetation communities, horned lark, and nesting birds to below a level of significance.

Though the project boundary occurs within a residential ai·ea which may provide suitable foraging habitat for this species, the project boundary itself contains a single tree which would provide mar inal value fo1· roostin°. .\ttachment I Sensitive Wildlife Species Occul'l'ing or with the Potential to Occur (I) = Introduced species STATUS CODES Listed/Proposed FE Listed as endangered by the federal government FT Listed as threatened by the federal government SE Listed as endangered by the state of California California fully protected species ilihfil CFP csc WL HMP List 1 California Department of Fish and Wildlife species of special concern California Department of Fish and Wildlife watch list species City of Carlsbad Habitat Management Plan S ecies Pro osed for Covera e under the Carlsbad Subarea Plan Hillside Drive Residence Project Page 6 ATTACHMENT 3 Project Compliance with City of Carlsbad Habitat Management Plan Conservation Standards within the Coastal Zone Attachment 3 Project Compliance with City of Carlsbad Habitat Management Plan Conse1·vation Standai·ds Resource/Habitat Management Plan Reference Environmentally Sensitive Habitat Areas (ESRA) 7-1 Coastal Sage Scrub 7-2 Wetlands 7-6 Wetlands 7-7 No Net Loss of Habitat 7-8 within the Coastal Zone Conservation Standard within the Coastal Zone ESRA shall be protected against significant disruption of habitat values. Only uses dependent on those resources shall be allowed within those areas. ESRA is defined as "any area in which plant or animal life or their habitats are either 1·are or especially valuable because of their special nature or role in an ecosystem and which could be easily disturbed or degraded by human activities and developments. Conserve a minimum of 67% of the coastal sage scrub habitat and 75% of the gnatcatchers on-site. No impacts to wetlands are allowed except where stated in California Public Resources Code Section 30233. If impacts to wetlands a.re allowed, mitigation shall be provided at a ratio of 3: 1 for riparian impacts and 4: 1 for impacts to saltwater or freshwater wetland, or marsh A no net loss standard applies to coastal sage scrub, maritin1e succulent scrub, southern maritime chaparral, southern mixed chaparral, native grassland, and oak woodland. Mitigation shall include a creation component that achieves the no-net-loss standard. Substantial restoration may be substituted for creation if approved by wildlife agencies and California Coastal Commission. Hillsdale Drive Residence Project Page 1 Project Compliance The project site consists of two non-sensitive land cover types: disturbed land and urban/developed, and is restricted by residential development on all sides. No sensitive plant or wildlife species were observed at the time of the survey. Though the project site has potential to supp01t one sensitive species that is adapted to disturbed lands, California horned lark (Eremophila alpestris), the project site as a whole provides low habitat value. As such, the project site would not meet the c1·iteria for ESRA as defined in the California Coastal Act and thus complies with this standard. The project site does not contain coastal sage scrub habitat; thus, the project meets this standard. The project site does not contain wetlands; thus, the project meets this standard. The project site does not contain wetlands; thus, the project meets this standard. The project site does not contain coastal sage scrub, maritime succulent scrub, southern maritime chaparral, southern mixed chaparral, native grassland, and oak woodland; thus, the project meets this standard.

On-site mitigation is not eligible for mitigation credit in the Coastal Zone. On-site or off- site areas may be used for mitigation if habitat is disturbed and suitable for 1·esto1·ation 01· enhancement, or if habitat is devoid of habitat value and therefore eligible for the 1: 1 creation/substantial restoration mitigation component. Mitigation should be provided within the Coastal Zone. Refer to 7-9 for more details, including mitigation ratios and habitat creation requirements (summarized in Table 6 below) (a) If more than 80% of property is covered with ESHA, at least 75% of the pmperty shall be conserved, OR (b) If the City approves a hardline preserve bounda1-y for these properties as part of the Habitat Management Plan, the amount of on-site prese1·vation as identified in the hardline boundary will apply. Mininrnm buffers between all preserved habitat and development are (a) 100 feet for wetlands; (b) 50 feet for riparian areas; (c) 20 feet for native uplands No development, grading, or alteration shall occur within a buffer except (a) Fuel modification in Zone 3 to max of 20 feet fo1· upland and non-riparian habitat, and not within 50 feet of riparian, wetland or oak woodland habitat; (b) some recreational trails and paths (see 7-11 f01· details) Buffer areas that do not contain native habitat will be landscaped using native plants. Hillsdale Drive Residence Project Page 2 Proiect Comnliance The project site is comprised of disturbed land and urban/developed, which is not considered a sensitive habitat type requiring the creation or restoration of habitat. The project will comply with the fee in lieu requirement for disturbed lands, as detailed in the project's mitigation. The pmject site does not contain ESHA 01· a Habitat Management Plan hardline preserve boundary that would require on-site preservation. Thus, the project is consistent with this standard. The project site is not adjacent to any wetlands, riparian, oak woodland, 01· native upland habitat that would requii·e a buffet area. Thus, the project is consistent with this standard. Attachment 3 Project Compliance with City of Cal'lsbad Habitat l\lanagement Plan Conservation Standa1·ds Resource/Habitat Management Plan Reference Grading and Landscaping 7-12 Parcel-specific Standards 7-13, 7-14 within the Coastal Zone Conservation Standard within the Coastal Zone See model grading ordinance in Carlsbad Maste1· Drainage Plan; (a) Grading in the Coastal Zone has generally been prohibited during the rainy season, October 1 to Ap1·il l; (however, pursuant to revisions to the City Zoning Ordinance processed through a Local Coastal Plan Amendment, grading is allowed if appropriate Best Management Practices (BMPs) are established); (b) All graded areas will be landscaped by October 1 to reduce el'Osion. Exceptions to these guidelines may be approved as described in 7-12. For example, habitat should not be cleared during the bird breeding season (September 15 -March 15) unless birds are cleared from the habitat fi.l'St. The following pl'Operties have parcel specific standards: (a) city owned lands adjacent to Macario Canyon and Veterans Memorial Park, and (b) specific parcels in Zones 20 and 21 that are located within biological core and linkage areas; see Habitat Manae:ement Plan 7-14 for a list. Hillsdale Drive Residence Project Page 3 Project Compliance All necessary grading requirements will be included as conditions for the pl'Oject on the grading plans, as approved by the City of Carlsbad. The project site does not consist of city owned lands adjacent to Macario Canyon or Veterans Memorial Park, and does not occu1· within a biological core and linkage area in Zone 20 and 21. Thus, the project is consistent with this standard. CAUTION Garage Door WILL NOT operate when Attic Ladder is in the lower position. Close stairs to operate.
