This study area was previously evaluated for biological resources In 2001 under the prior owner. New surveys were conducted in 2015 and mitigation sites were assessed in 2017; this letter report serves to update the study area existing conditions, proposed project impacts, and proposed mitigation. The proposed project would result in the creation of a 15-lot subdivision in the northern portion of the study area at the southern terminus of Twain Avenue. The proposed subdivision would be composed of 13 single-family residential lots, each at a minimum of 8,000 square feet: 1 private street lot: 1 Habitat Management Plan open space lot, and 1 water quality basin lot. This biological resources letter report provides a description of the project location and a summary of the pertinent biological resource regulations, and discusses the survey methods, existing biological resources, special-status biological resources, project impacts (direct and indirect), and project mitigation. The project impacts, avoidance, and mitigation measures are discussed in a regulatory context. 1 Pr0Ject Location The Hynek property is located within the City of Carlsbad In northwestern San Diego County, California. The study area is located within the Kelly Ranch neighborhood in Carlsbad (Figure 1) and Is within the City of Carlsbad Habitat Management Plan (Carlsbad HMP), Local Facilities Management Zone (LMFZ) 8. The Carlsbad HMP serves as the City's subarea plan under the North County Multiple Habitat Conservation Program (MHCP) (City of Carlsbad 2004) (Figure 2). The proJect is referred to as the KirgIs property in the HMP. The study area is located within Township 12 South, Range 4 West, Section 16 (Figure 2) on the 7 .5-minute U.S. Geological Survey San Luis Rey quadrangle map. The approximate centroid of the site is 33 °8'15.404"N and 117 ° 17'52.59"W. 1.1 Topography and Land Uses Elevation on the study area ranges from approximately 165 to 328 feet above mean sea level (amsl) and consists of several ridges with gently sloping canyons adjacent to housing developments. Coastal sage scrub occurs primarily along the western and central portions of the study area, with chaparral occurring in the eastern portions of the study area. There are several dirt trails throughout the study area, as the property connects with the Kelly Ranch DUDEI< 1 9012 January 2019 Ms. Gay/ Hynek Subject: Biological Resources Letter Report and Impacts Analysis, Hynek Property, City of Carlsbad, San Diego County, California open space area to the south. The Crossings at Carlsbad golf course also lies south of the study area. To the north and east of the study area are residential and commercial developments, and to the west is open space and, approximately 1 mile from the project site. Agua Hed1onda Lagoon. 1.2 Soils Soils on the study area are mapped as Loamy alluvial land-Huerhuero complex, 9%-50% slopes, severely eroded; Marina loamy coarse sand. 2%-9% slopes; Las Flores loamy fine sand, 15%-30% slopes, eroded; and Huerhuero loam, 2%-9% slopes. These soils are generally either moderately well drained or somewhat excessively drained (USDA 2015). 2 Regulatory Context This section describes the regulatory framework relevant for this proJect. 2 1 Federal The federal Endangered Species Act (FESA) of 1973 (16 U.S.C. 1531 et seq.). as amended, is administered by U.S. Fish and Wildlife Service (USFWS) for most plant and animal species and by the National Oceanic and Atmospheric Administration National Marine Fisheries Service for certain marine species. This legislation is intended to provide a means to conserve the ecosystems endangered and threatened species depend on, and provide programs for the conservation of those species, thus preventing extinction of plants and wildlife. FESA defines an endangered species as "any species that is m danger of extinction throughout all or a significant portion of its range." A threatened species is defined as "any species that is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range." Under FESA, it is unlawful to take any listed species: "take" Is defined as ·'harass. harm, pursue. hunt, shoot. wound. kill, trap, capture, or collect. or to attempt to engage in any such conduct." FESA allows for the issuance of Incidental Take Permits for listed species under Section 7, which Is generally available for projects that also require other federal agency permits or other approvals, and under Section 10, which provides for the approval of habitat conservation plans on private property without any other federal agency involvement. Upon development of a habitat conservation plan, USFWS can issue Incidental Take Permits for listed species. Pursuant to Section 404 of the Clean Water Act. the U.S. Army Corps of Engineers {ACOE) regulates the discharge of dredged and/or fill material into waters of the United States. The term "wetlands" (a subset of waters) is defined in 33 CFR 328.3(b) as "those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas." In the absence of wetlands, the limits of ACOE jurisdiction in non-tidal waters, such as intermittent streams, extend to the ordinaiy high water mark, as defined m 33 CFR 328.3{e). Pursuant to Section 10 of the Rivers and Harbors Appropriation Act of 1899, the ACOE regulates any potential obstruction or alteration of any navigable water of the United States. DUDEI< 2 9012 January 2019 Ms. Gay/ Hynek Subject: Biological Resources Letter Report and Impacts Analysis, Hynek Property, City of Carlsbad, San Diego County, California The Migratory Bird Treaty Act was originally passed In 1918 as four bilateral treaties, or conventions, for the protection of a shared migratory bird resource. The primary motIvatIon for the international negotiations was to stop the "indiscriminate slaughter" of migratory birds by market hunters and others (16 U.S.C. 703 et seq.}. Each of the treaties protects selected species of birds and provides for closed and open seasons for hunting game birds. The Migratory Bird Treaty Act protects over 800 species of birds. Two species of eagles that are native to the United States, the bald eagle (Ha/iaeetus leucocephalus) and golden eagle (Aquila chrysaetos), were granted additional protection within the United States under the Bald and Golden Eagle Protection Act (16 U.S.C. 668 et seq.) to prevent the species from becoming extinct. 2 2 State The California Department of Fish and Wildlife (CDFW, formerly California Department of Fish and Game) administers the California Endangered Species Act (CESA; California Fish and Game Code, Section 2050 et seq.), which prohibits the take of plant and animal species designated by the California Fish and Game Commission as endangered or threatened In the State of California. Under CESA Section 86, "take" Is defined as "hunt. pursue, catch, capture, or kill, or attempt to hunt. pursue, catch, capture, or kill." CESA Section 2053 stipulates that state agencies may not approve projects that will "jeopardize the continued existence of any endangered species or threatened species, or result in the destruction or adverse mod1fIcatIon of habitat essential to the continued existence of those species, if there are reasonable and prudent alternatives available consistent with conserving the species or its habitat which would prevent Jeopardy." CESA defines an endangered species as "a native species or subspecies of a bird, mammal, fish, amphIbIan, reptile, or plant which is in serious danger of becoming extinct throughout all, or a significant portion, of its range due to one or more causes, including loss of habitat, change in habitat, overexploitation, predation, competition, or disease." CESA defines a threatened species as "a native species or subspecies of a bird, mammal, fish, amphibian, reptile, or plant that. although not presently threatened with extinction, is likely to become an endangered species m the foreseeable future in the absence of the special protection and management efforts required by this chapter. Any animal determined by the Commission as rare on or before January 1, 1985, is a threatened species." A candidate species is defined as "a native species or subspecies of a bird, mammal, fish, amphibian, reptile, or plant that the Commission has formally noticed as being under review by the department for addition to either the list of endangered species or the list of threatened species, or a species for which the Commission has published a notice of proposed regulation to add the species to either list." CESA does not list invertebrate species. Sections 2081(b) and 2081(c) of the California Fish and Game Code authorizes take of endangered, threatened, or candidate species if take is incidental to otherwise lawful activity and 1f specific cntena are met. These provisions also require CDFWto coordinate consultations with USFWS for actions involving federally listed species that are also state- listed species. In certain circumstances, Section 2080.1 of CESA allows CDFW to adopt a federal incidental take statement or a 10(a) permit as its own, based on its findings that the federal permit adequately protects the species and Is consistent with state law. A Section 2081(b) permit may not authorize the take of "fully protected" species and uspecified birds" (California Fish and Game Code, Sections 3505, 3511, 4700, 5050, 5515, and 5517). If a project is planned in an area where a fully protected species or a specified bird occurs, an applicant must design the project to avoid take. DUDEI( 3 9012 January 2019 Ms. Gay/ Hynek Subject: Biological Resources Letter Report and Impacts Analysis, Hynek Property, City of Carlsbad, San Diego County, California Pursuant to Section 1602 of the California Fish and Game Code, CDFW regulates all diversions, obstructions, or changes to the natural flow or bed, channel, or bank of any river, stream, or lake that supports fish or wildlife. A Stream bed Alteration Agreement is required for impacts to Jurisdictional wetlands in accordance with Section 1602 of the California Fish and Game Code. Section 2835 of the California Fish and Game Code allows CDFW to authorize incidental take in a natural communities conservation plan (NCCP). Take may be authorized for identified species whose conservation and management is provided for in the NCCP, whether or not the species is listed as threatened or endangered under FESA or CESA, provided that the NCCP complies with the conditions established in Section 2081 of the California Fish and Game Code. The NCCP provides the framework for the Carlsbad HMP. 2.3 Cal1forn1a Coastal Act Under the California Coastal Act (CCA} (California Public Resources Code, Section 30000 et seq.), the California Coastal Commission regulates impacts to wetlands In the "coastal zone" and requires a coastal development permit for almost all development within this zone. From 3 miles seaward, the coastal zone generally extends approximately 1,000 yards inland. ln less developed areas, It can extend up to 5 miles inland from the mean high tide line, but can also be considerably less than 1,000 yards inland In developed areas. The CCA also protects designated sensitive coastal areas by providing additional review and approvals for proposed actions in these areas. Section 30121 of the CCA defines wetlands as "lands within the coastal zone which may be covered periodically or permanently with shallow water and include saltwater marshes, swamps. mudflats, and fens." The CCA allows disking, filling, or dredging of wetlands for certain uses, such as restoration. The CCA also directs each city or county within the coastal zone to prepare a Local Coastal Program for California Coastal Commission certification (California Public Resources Code, Section 30000 et seq.}. In contrast to ACOE, which uses a three-parameter definition to delineate wetlands, the Galifornia Coastal Commission essentially uses the CowardIn method of wetlands classification, which defines wetland boundaries by a single parameter (i.e., hydric soils, hydrophytic vegetation, or hydrology) (Cowardin et al. 1979). 2.4 California Environmental Quality Act The California Environmental Quality Act (CEQA) requires identification of a proJect's potentially significant impacts on biological resources and ways that such impacts can be avoided, minimized, or mitigated. The act also provides guidelines and thresholds for use by lead agencies for evaluating the significance of proposed impacts. 2 4.1 Spec1al-Stat·,JS n:i'ltS and Wildlife The CEQA Guidelines (14 CCR 15000 et seq.) define endangered animals or plants as species or subspecies whose "survival and reproduction in the wild are In immediate jeopardy from one or more causes. including loss of habitat. change in habitat, overexploitation, predation, competition, disease, or other factors" (14 CCR 15380(b)(1)). A rare animal or plant Is defined in CEQA Guideline 15380(b)(2) as a species that, although not currently threatened with extinction. exists "in such small numbers throughout all or a significant portion of its range that it may become endangered if its environment worsens; or ... [t]he species Is likely to become endangered within the foreseeable DUDEI< 4 9012 January 2019 Ms. Gay/ Hynek Subject: Biological Resources Letter Report and Impacts Analysis, Hynek Property, City of Carlsbad, San Diego County, California future throughout all or a significant portion of its range and may be considered 'threatened' as that term 1s used in the federal Endangered Species Act." Additionally, an animal or plant may be presumed to be endangered, rare, or threatened 1f it meets the criteria for listing, as defined further in CEQA Guideline 15380{c). For purposes of this impact analysis, species are considered sensitive If they are (1) listed or proposed for listing by state or federal agencies as threatened or endangered (CDFW 2015a, 2015b); (2) plant species with a California Rare Plant Rank (CRPR) (formerly California Native Plant Society {CNPS) List) 1 through 4 {CNPS 2015); (3) covered under the Carlsbad HMP (City of Carlsbad 2004); or (4) considered California Species of Special Concern (SSC) or California Fully Protected Species {FP) {CDFW 2015c, 2015d, 2015e) or Birds of Conservation Concern (BCC) (USFWS 2008). Some mammals and birds are protected by the state as fully protected species, as described in the California Fish and Game Code. Sections 4700 and 3511, respectively. Fully protected species may not be taken or possessed without a permit from the California Fish and Game Commission, and no permit Is available for the incidental take of a fully protected species. Species considered state candidates for listing as threatened or endangered are subJect to the taking proh1bitIons and provisions under CESA as if the species were listed. 2 4.2 Soec:ial-Statuc, Vegetat,on C1rrn1ulllt12s Appendix G of the CEQA Guidelines (14 CCR 15000 et seq.) requires an evaluation of impacts to "any riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations, or by the California Department of Fish and Game1 or the U.S. Fish and Wildlife Service." For the purposes of this analysis, native vegetation communities identified as requiring m1t1gation under the Carlsbad HMP are considered special status due to having been identified in a local and regional conservation plan. 2.5 North County Multiple Habitat Conservation Program The North County MHCP is a long-term regional conservation plan established to protect sensitive species and habitats in northern San Diego County. The North County MHCP is divided into seven subarea plans-one for each jurisdiction within the North County MHCP-that are permitted and implemented separately from one another. The City of Carlsbad is the only city under the North County MHCP that has an approved and permitted subarea plan (1.e., the Carlsbad HMP} (City of Carlsbad 2004). The North County MHCP sets forth general and subarea condItIons of coverage that must be met for each covered species in order for the Cities of Carlsbad, Encinitas, Escondido, Oceanside, San Marcos, Solana Beach, and Vista to obtain take authorization. These conditions can be found In Appendix C of the Carlsbad HMP. 1 Effective January 1, 2013, the California Department of Fish and Game changed its name to the CDFW. In this document. references to guidance or documents prior to the official name change use California Department of Fish and Game, whereas references after the name change use CDFW. References in quoted material are not altered. DUDEI< 5 9012 January 2019 Ms. Gay/ Hynek Subject: Biological Resources Letter Report and Impacts Analysis, Hynek Property, City of Carlsbad, San Diego County, California carlsbad Habitat Management Plan The Carlsbad HMP was adopted by the City in December 1999, and the final approvals from USFWS and CDFW, including implementing agreement and terms and conditions, were granted in November 2004. The purpose of the Carlsbad HMP Is to guide the design, management, monitoring, and public use of the preserve system. The Carlsbad HMP calls for 6,478 acres of natural habitat to be preserved within the City, as well as an additional 308 acres of habitat for the coastal California gnatcatcher (Polioptila californica ca//fornica) within the City or County gnatcatcher core area. The Carlsbad HMP identifies LMFZs, which were developed based on the distribution of existing vegetation communities and sensitive species. The zones were further broken down into Carlsbad HMP cores, linkages, and special resource areas. The proposed project is within a Standards Area, identified in the HMP as the Kirgis property, and must be developed consistent with LMFZ 8 specific standards. These standards include avoidance of impacts to Narrow Endemic plant populations, 25% total development allowance, and a requirement to place development m the least environmentally sensitive portion of the property. 3 Methods Data regarding biological and jurisdictional resources present within the proJect study area were obtained through a review of pertinent literature and field reconnaissance; both are described in detail In the following text. The review of pertinent literature and field reconnaissance was conducted in June and July 2015. 3 1 Literature Review The following data sources were reviewed to assist with the biological efforts: • CDFW CNDDB {2015c) • CNPS Inventory of Rare and Endangered Plants (2015) • Biological Constraints Analysis of Kirgis Property Encinitas, California (Dudek & Associates 2000a) • Sensitive Plant Survey of Kirgis Property Carlsbad {Dudek & Associates 2000b) • Wilson Residences Initial Study/Environmental Checklist {Dudek & Associates 2002) • USFWS Species Occurrence Data (2015) 3.2 Field Reconnaissance Initial field surveys were petiormed in 2001 for the prior property owner. These surveys were conducted by Dudek Biologists Darren Smith, Julie Vanderwier, Jeff Priest, and Myloc Nguyen and by Shana Dodd of S.C. Biological Consulting. An update to the previous field surveys was conducted by Dudek Biologists Emily Wier and Kathleen Dayton in June 2015 {Table 1). The biological surveys included protocol-level presence/absence surveys for coastal California gnatcatcher, the mapping of vegetation communities and land covers present, and rare plant surveys within the project study area. An evaluation of wetlands and waters of the United States were also evaluated during DUDEI< 6 9012 January 2019 Ms. Gay/ Hynek Subject: Biological Resources Letter Report and Impacts Analysis, Hynek Property, City of Carlsbad, San Diego County, California surveys maximize the number of observations ofth1s portion of the fauna. In contrast, daytime surveys usually result 1n few observations of mammals, many of which may only be active at night. In addition, many species of reptiles and amphibians are secretive in their habits and are difficult to observe using standard meandering transects. Pitfall trapping 1s the most effective technique tor detecting many of these species: however, such trapping was beyond the scope of this project. Therefore, identification of mammals primarily relied on detection of surface sign, such as scat. burrows, and tracks. 4 Results 4.1 Vegetation Communities and Land Covers Five vegetation communities and land cover types, totaling 21.8 acres, were identified within the study area during the biological resources evaluation: D1egan coastal sage scrub-coastal form (including disturbed form), southern maritime chaparral, disturbed habitat, and urban/developed. These vegetation communities and land cover types are described in the following text, their acreages are presented in Table 2, and their spatial distributions are presented on Figure 3. Table 2.

Many of the taxa w1th1n this community are facultatively drought dec1du ous. Diegan coastal sage scrub-coastal form occurs below 1,000 feet and is dominated by coastal sagebrush (Artemisia californica). Other associated dominants may include Eastern Mojave buckwheat (Eriogonum fascicu/atum var. fascicu/atum), snapdragon penstemon (Keck/el/a antirrhinoides), laurel sumac (Malosma laurina), lemonade sumac (Rhus integrifo/ia), DUDEI< g 9012 January 2019 Ms. Gay/ Hynek Subject: Biological Resources Letter Report and Impacts Analysis, Hynek Property, City of Carlsbad, San Diego County, California species; and wart-stemmed ceanothus (Ceanothus verrucosus), a CRPR 2B.2 species {Figure 3).2 A brief description of each species observed in the study area is provided in the following text. There are eight special-status plant species that have a moderate or high potential to occur on the study area: chaparral sand-verbena (Abronia vi/losa var. aurita), a CRPR 1B.1 species; decumbent goldenbush (lsocoma menziesii var. decumbens), a CRPR 18.2 species; Del Mar manzanita (Arctostaphylos glandu/osa ssp. crassifo/ia), a federally listed endangered, CRPR 1B.1, and Carlsbad HMP List 3, Narrow Endemic species; Palmer's grappl1nghook (Harpagonella palmer0, a CRPR 4.2 species: Robinson's pepper grass (Lepidium virginicum var. robinsoni1), a CRPR 4.3 species; small- flowered morning glory (Convo/vu/us simu/ans), a CRPR 4.2 species: summer holly (Comarostaphylis diversifo/ia ssp. diversifolia), a CRPR 1B.2 and Carlsbad HMP List 3 species; and western d1chondra (Dichondra occidentalis), a CRPR 4.2 species. Palmer's grapplinghook, small-flowered morning glory, summer holly, and western dichondra were observed in the study area during surveys conducted in 2001 (Dudek & Associates 2002). Galifomia adolphia (Adolph/a californica), CRPR 2B.1 California adolphia is a native shrub less than 1.5 meters (4.9 feet) tall. Thts species is found below 400 amsl in coastal scrub and chaparra! areas and flowers from December to April. Within the study area, California adolphia Is found in several locations within the Diegan coastal sage scrub community. The species is spread throughout the site in approximately four large patches in the eastern section of the study area and several smaller patches throughout the western half (Figure 3). Ashy spike-moss (Se/ag/nel/a cinerascen), CRPR 4.1 Ashy spike-moss Is a perennial rhizomatous herb. This species is found below 640 meters (2,100 feet) amsl in coastal scrub and chaparral (CNPS 2015). Given the low sens1t1vity status and spreading nature of this species, the exact locations of individuals of this species on site have not been mapped. Golden-rayed pentachaeta (Pentachaeta aurea ssp. aurea), CRPR 4.2 Golden-rayed pentachaeta Is an annual herb. This species Is found between 80 and 1.850 meters (262 and 6,070 feet) amsl in chaparral and coastal scrub. Flowers with a yellow to brown-orange color bloom between March and July {CNPS 2015; Jepson Flora Project 2013). Given the low sens1t1vity status of this species. the exact locations of individuals of this species on site have not been mapped. Nuttall's scrub oak (Querous dumosa), CRPR 1B.1 Nuttall's scrub oak is a native shrub that can reach 1-4 meters In height and is generally an evergreen. The species 1s found below 200 amsl in generally sandy soils near the coast, sandstone, chaparral. or coastal-sage scrub areas. 2 Only species with CRPR of 1, 2, or 3 were mapped. DUDEI( 12 9012 January 2019 Ms. Gay/ Hynek Subject: Biological Resources Letter Report and Impacts Analysis, Hynek Property, City of Carlsbad, San Diego County, California Within the study area, Nuttall's scrub oaks were found in the southern maritime chaparral habitat on the southeastern section of the site. The population ranged from 100 to 200 individuals. Another individual was identified in the northeastern part of the study area (Figure 3). Wart-stemmed ceanothus (Ceanothus verrucosus), CRPR 2B.2 Wart-stemmed ceanothus Is a perennial evergreen shrub found between 1 and 380 meters (3 and 1,247 feet) In chaparral habitats (CNPS 2015). Within the study area, this species was found in southern maritime chaparral in the northeastern section of the site (Figure 3). 4.4 Special-Status Wildlife Species Endangered, rare, or threatened wildlife species, as defined in CEQA Guidelines, Section 15380(b) (14 CCR 15000 et seq.), are referred to as ~special-status wildlife species" and, in this report, include (1) endangered or threatened wildlife species recognized in the context of CESA and FESA (CDFW 2015a, 2015c); (2) California SSC and Watch List (WL) species, as designated by the CDFW (2015c, 2015e); (3) mammals and birds that are fully protected species, as described in the California Fish and Game Code, Sections 4700 and 3511; (4) BCC-designated species {USFWS 2008); and (5) wildlife species covered under the Carlsbad HMP (City of Carlsbad 2004). A search of CNDDB records was used to develop a matrix of special-status wildlife species that may have potential to occur on site due to the presence of suitable habitat (taking into consideration vegetation communities, soils, elevation, geographic range, life form/blooming period, and others). Appendix D provides an assessment of each special-status wildlife species' potential to occur on the study area based on the findings of the field investigations. Two special-status species were observed on site during biological surveys. The coastal California gnatcatcher is a federally listed threatened species and a CDFW SSC and is covered under the Carlsbad HMP. The northern harrier (Circus cyaneus) Is a CDFW SSC. A brief descnption of each of the species observed In the study area is provided in the following text. There are five special-status wildlife species with moderate or high potential to occur in the study area: Betding's orange-throated whiptail (Aspidoscelis hyperythra, SSC/Covered), Bla1nv1lle's horned lizard (Phrynosoma b/ainvillii, SSC), Bell's sage sparrow (Amphispiza be/Ii be/Ii, BCC/WL}, southern California rufous--crowned sparrow (Aimophila ruficeps canescens, WL/Covered), and northwestern San Diego pocket mouse (Chaetodipus fa/lax fa/lax, SSC). Belding's orange-throated wh1ptail and northwestern pocket mouse were observed within the study area during surveys conducted in 2001 (Dudek & Associates 2002). Coastal California gnatcatcher (Polloptlfa califomica ca//fornica) The coastal CalIfornIa gnatcatcher Is a federally listed threatened species and a CDFW SSC. It Is closely associated with coastal sage scrub habitat and typically occurs below 950 feet elevation and on slopes less than 40% {Atwood 1990), but coastal California gnatcatcher have been observed at elevations greater than 2,000 feet. The species is threatened primarily by loss, degradation, and fragmentation of coastal sage scrub habitat, and Is also impacted by brown-headed cowbird (Mo/othrus ater) nest parasitism (Braden et al. 1997). DUDEI( 13 9012 January 2019 Ms. Gay/Hynek Subject: Biological Resources Letter Report and Impacts Analysis, Hynek Property, City of Carlsbad. San Diego County, California A total of four coastal California gnatcatcher individuals were observed in the study area during the protocol-level surveys, including two pairs of coastal California gnatcatcher (Figure 3). No nests, nesting behavior, or Juveniles were observed in the study area. Northern harrier (Circus cyaneus) The northern harrier Is a California SSC. This species Is found year-round in California from below sea level up to 10,000 feet In elevation In marshes, grasslands, and in open spaces (MacWhirter and Bildstein 2011). The species Is threatened primarily by loss and degradation of nesting and foraging habitat. Other threats include nest failure from human disturbance. predator-control projects, agricultural practices, and unnatural predation pressure {Shuford and Gardali 2008). A northern harrier was observed on two different occasions during biological reconnaissance surveys. This species was not mapped because it was observed foraging over the site. It is presumed that this species nests and forages within the Agua Hedionda Lagoon, approximately 1 mile west of the study area. Critical Habitat Almost the entire study area Is located within USFWS-designated critical habitat for the coastal California gnatcatcher (72 FR 72010-72213). A thin area along the northernmost border of the study area is not within critical habitat. 4.5 Wildlife Corridors and Habitat Linkages Wildlife corridors are linear features that connect large patches of natural open space and provide avenues for dispersal or migration of animals, as well as dispersal of plants (e.g., via wildlife vectors). Wildlife corridors contribute to population viability in several ways: (1) they assure continual exchange of genes between populations, which helps maintain genetic diversity; (2) they provide access to adjacent habitat areas representing additional territory for foraging and mating; (3) they allow for a greater carrying capacity; and (4) they provide routes for colonization of habitat lands following local population extinctions or habitat recovery from ecological catastrophes (1.e., the rescue effect). Habitat linkages are stretches of native habitat that function to join two larger habitat areas. These stretches may be represented by continuous patches of habitat or by nearby habitat "islands" that function as stepping stones for dispersal and movement (especially for birds and flying insects). These linkages function as connectors that reduce the adverse effects of habitat fragmentation. Habitat fragmentation may lead to decreased gene flow for small animals, such as reptiles, amphibians, and rodents. The areas to the north and east of the study area are mostly residential and commercial development (along Faraday Avenue), with native vegetation surrounding part of the project boundary and interspersed throughout the developed areas. The study area's southern boundary consists of the Kelly Ranch open space and the Crossings at Carlsbad golf course, and the western boundary consists of open space that eventually leads to the Agua Hedionda Lagoon. The Hynek property is located within Local Facility Management Zone 8. Local Facility Management Zone 8 is largely made up of core habitat areas, and the Hynek property serves as a significant component of this core area. The DUDEI< 14 9012 January 2019 Ms. Gay/ Hynek Subject: Biological Resources Letter Report and Impacts Analysis, Hynek Property, City of Carlsbad, San Diego County, California core habitat within Local Facility Management Zone 8 is connected to other core habitat areas identified in the Carlsbad HMP via linkage areas to the northeast, southeast, and west (City of Carlsbad 2004). Given the current design of the Carlsbad HMP reserve, it is likely that the Hynek property will continue to function as a regional wildlife dispersal corridor and will serve as a site for occupation by wildlife for breeding and foraging. 5 ProJect Impacts This section addresses direct impacts and 1nd1rect impacts that will result from implementation of the Project. Direct Impacts may include both the permanent loss of on-site habitat and the plant and wildlife species that it contains and the temporary loss of on-site habitat. Direct impacts were quantified by overlaying the proposed project plans onto the biological resources map; the development footprint includes proposed grading and fuel management zones 1 and 2 and is considered a permanent direct impact. A 20-foot upland buffer 1s required between the development footprint and open space; this buffer include fuel management zone 3 and 1s considered impact-neutral. A proposed trail easement extends on the northern edge of the proposed development and connects with an existing trail. The portion of the trail within the development is considered a permanent direct impact; the portion of the trail within the 20-foot upland buffer and within the open space is considered impact neutral as no improvements to the existing trail are proposed. Indirect Impacts refer to off-site and on-site effects that are either short-term impacts (i.e., temporary) due to project construction or long-term impacts (i.e., permanent) due to the design of the proposed proJect and the effects 1t may have on adJacent resources. For this proposed project, it is assumed that the potential indirect impacts resulting from construction act1vit1es may include dust, noise, general human presence that maytemporarilydisruptspecies and habitat vitality, and construction-related soil erosion and runoff. With respect to these latter factors, however, project grading will be subject to the typical restrictions (e.g., best management practices (BMPs)) and requirements that address erosion and runoff, including the federal CWA, National Pollution Discharge Elimination System (NPDES), and preparation of a Water Pollution Control Plan. Long-term indirect impacts associated with the proposed project may include adverse edge effects, such as intrusions by humans and domestic pets, noise, lighting, invasion by exotic plant and wildlife species, effects oftox1c chemicals (fertilizers, pesticides, herbicides, and other hazardous materials), urban runoff from developed areas, srnl erosion, litter, fire, and hydrological changes {e.g., groundwater level and quality). These indirect impacts could be significant if not addressed through the implementation of proper construction monttoring and design of the proposed project's development-habitat edge. BMPs will be implemented when construction begins. Additionally, any preserved open space areas would be protected via fencing or other means from trespassing and dumping of trash. 5.1 Direct Impacts Vegetation Communities Implementation of the proposed project will result in permanent direct impacts to 4.64 acres of native and non- native vegetation communities and land covers, including 4.13 acres of Diegan coastal sage scrub-coastal form (including disturbed Diegan coastal sage scrub-coastal form (Table 3). No temporary direct impacts will occur as a result of project 1mplementat1on.

Direct permanent impacts to native habitats, including Diegan coastal sage scrub-coastal form and disturbed Diegan coastal sage scrub- coastal form, requtre mitigation according at a 2:1 ratio as established by the City (2008) and include a requirement to provide no-net-loss of habitat within the Coastal Zone. Special-Status Plants Implementation of the proposed project would not result in the loss of any state-or federal listed threatened or endangered plant species. Five special-status plant species were observed within the study area. Ashy spike-moss and golden-rayed pentachaeta are CRPR 4 species, indicating they have limited sensitivity, and are not covered under the Carlsbad HMP. Therefore, impacts to these species would be considered less than significant. Wart-stemmed ceanothus and Nuttall's scrub oak were mapped in the study area but were outside the project impact area (see Figure 4). Although these species were not detected within the project impact footprint, suitable coastal scrub habitat for Nuttall's scrub oak is present within the impact footprint and direct impacts to Nuttall's scrub oak may occur as a result of proJect 1mplementatIon. BMPs and other construction-related measures will reduce these impacts to less than significant. These measures would also ensure that no impacts occur to the Nuttall's scrub oak w1thIn the study area. California adotphia, a CRPR 2B.1 species, occupies approximately 1.01 acres in the study area. In addition, suitable coastal scrub habitat for California adolphia is present within the impact footprint. Implementation of the proposed proJect would result in the direct permanent loss of 0.01 acre occupied by California adolophia along the southwest edge of the impact footprint; additional direct impacts to this species may occur as a result of project implementation due to the presence of suitable coastal scrub habitat within the impact footprint. BMPs and other construction-related measures will reduce these impacts to less than significant. Eight special-status plant species are considered to have a high or moderate potential to occur in the study area: chaparral sand-verbena, decumbent goldenbush, Del Mar manzanita, Palmer's grapplinghook, Robinson's pepper- grass, small-flowered morning glory, summer holly, and western dichondra. Direct impacts to Del Mar manzanita and summer holly are not expected because of a lack of suitable chaparral habitat within the impact footprint. Palmer's DUDEI< 16 9012 January 2019 Ms. Gay/ Hynek Subject: Biological Resources Letter Report and Impacts Analysis. Hynek Property, City of Carlsbad, San Diego County, California grapplinghook, Robinson's pepper grass, small-flowered morning glory, and western dichondra are CRPR 4 species, indicating they have limited sensitivity, and are not covered under the Carlsbad HMP. Therefore, impacts to these species would be considered less than significant Although chaparral sand-verbena and decumbent golden bush were not detected in the study area, suitable coastal scrub habitat for these species is present within the impact footprint, and direct impacts to these CRPR 1 species may occur as a result of project implementation. BMPs and other construction-related measures will reduce these impacts to less than significant. Special-status Wildlife Two pairs of coastal California gnatcatchers (Federally Threatened/SSC/Covered) were observed w1thIn the study area. One pair is located on the eastern edge of the impact area {see Figure 4). Northern harrier (SSC) was observed foraging within the study area. Beld1ng's orange-throated whiptatl was observed within the study area during surveys conducted in 2001 (Dudek & Associates 2002) and is considered to have a high potential to occur on site. An additional four special-status species have a high or moderate potential to occur within the study area: Blainv1lle's horned lizard (SSC), Bell's sage sparrow (BCC/WL), southern California rufous-crowned sparrow {WL/Covered}, and northwestern San Diego pocket mouse (SSC). Because Bell's sage sparrow, coastal California gnatcatcher, northern harrier, and southern California rufous-crowned sparrow are highly mobile bird species, it Is unlikely that the proposed project would result in the direct loss of 1nd1vidual birds. Avoidance measures would be implemented to avoid impacts during the nesting season for these species. Direct impacts to three state species of concern-Blainville's coast lizard, northwestern San Diego pocket mouse, and Belding's orange- throated whiptail-could occur as a result of project implementation. However, because these species are common throughout the region and suitable habitat will be conserved within the study area, these impacts would not be considered significant. The study area supports native habitats m and adJacent to the proposed proJect site that could provide potential nesting and foraging habitat for a variety of songbirds and raptors in the area, including Belt's sage sparrow, coastal California gnatcatcher, northern harrier, and southern California rufous-crowned sparrow. If work were to occur during the breeding season for nesting birds (February 15 through September 15 for most bird species, and January 1 through August 31 for raptors), potential direct impacts to nesting individuals could occur. Such impacts would be considered significant. Impacts to nesting bird species covered under the Migratory Bird Treaty Act would be mitigated through construction avoidance of the bird breeding season or pre-construction breeding bird surveys. Habitat impacts will be mitigated according to ratios defined by the Carlsbad HMP and will help offset any potential impacts to special-status species. Wildlife Corridors and Habitat Linkages The proposed proJect is an extension of already existing development north of the impact area and will not create additional fragmentation of habitat or habitat islands. Wildlife access to the native habitat north and south of the site will remain intact, along with access to the Agua Hedionda Lagoon. Although wildlife movement may be disrupted temporarily during construction due to noise or increased human presence, these impacts are considered temporary in nature, and implementation of the proposed project will not result in permanent direct impacts to wildlife movement functions. Following construction, wildlife will continue to use the site to aid in movement to other areas of biological value. Therefore, direct, permanent impacts to wildlife corridors/habitat linkages are not anticipated. DUDEI< 17 9012 January 2019 Ms. Gay/ Hynek Subject: Biological Resources Letter Report and Impacts Analysis, Hynek Property, City of Carlsbad, San Diego County, California 5.2 Indirect Impacts Vegetation Communities Indirect impacts may result from (1) temporary, short-term effects due to construction activity; and (2) long-term effects from development. Indirect impacts to vegetation communities in general would primarily result from adverse ''edge effects.tt During construction, edge effects may include impacts related to the generation of fugitive dust, which could disrupt plant vitality in the short-term, and changes in hydrology, including sedimentation and erosion. Potential long-term indirect impacts include trampling by humans traveling off trail, invasion by exotic plants, exposure to urban pollutants (fertilizers, pest1c1des, herbicides, and other hazardous materials), increase or decrease in natural fire regime, srnl erosion, and hydrologic changes (e.g., surface and groundwater level and quality). These short-term and long-term impacts are described in more detail in the following text. Fugitive Dust Excessive dust can decrease the vigor and productivity of vegetation through effects on light, penetration, photosynthesis, resp1rat1on, transpiration, increased penetration of phytotox1c gaseous pollutants, and increased incidence of pests and diseases. These effects will be limited by the implementation of BMPs that would reduce fugitive dust. Chemical Pollutants. The introduction of chemical pollutants, such as herbicides, pest1c1des, or insecticides, could result in potential impacts to special-status species through direct or indirect consumption of the pollutant. Chemical pollutants can degrade native habitats and water quality over time. BMPs and requirements that address erosion and runoff, including the federal CWA, NPDES, and preparation of a Water Pollution Control Plan, will mitigate for impacts associated with chemical pollutants. Increased Human Activity. Increased human activity could result 1n the potential for trampling of vegetation outside of the impact footprint, as well as soil compaction, and could affect the viability of plant communities. Trampling can alter the ecosystem, creating gaps 1n vegetation and allowing exotic, non-native plant species to become established, leading to soil erosion. Trampling may also affect the rate of rainfall interception and evapotranspirat1on, soil moisture, water penetration pathways, surface flows, and erosion. BMPs and other design features will mitigate for impacts associated with an increased human presence in the area. All grading will be subject to the implementation of BMPs and typical restrictions and requirements that address dust control, erosion, and runoff, including the federal Clean Water Act and NPDES. The following design features would be included to reduce the potential for indirect impacts to special-status plants: • Signs will be placed at key access points, describing the sensitive biological resources in the surrounding areas and identifying the allowable and prohibited uses in these areas. • Fugitive dust will be avoided and minimized through watenngand other appropriate measures. • To avoid attracting predators of the target species of concern, the project site shall be kept as clean of debris as possible. All food-related trash 1temsshall be enclosed in sealed containers and regularly removed from the site. Pets of project personnel shall not be allowed on site where they may come into contact with any listed species. DUDEI< 18 9012 January 2019 Ms. Gay/Hynek Subject: Biological Resources Letter Report and Impacts Analysis, Hynek Property, City of Carlsbad, San Diego County, California Furthermore, all native habitats not permanently impacted within the study area will be protected in accordance with the Carlsbad HMP, which requires a 20-foot buffer around all native habitats. Approximately 0.57 acre of Diegan coastal sage scrub-coastal form and 0.05 acre of disturbed Diegan coastal sage scrub-coastal form are within 20 feet of the permanent impact footprint. Retaining this buffer will further limit the indirect impacts to the remaining native habitats on site that will result from implementation of the proposed project. Special-Status Plants The potential indirect impacts to vegetation communities cited previously could potentially affect special-status plant species found within the study area. Standard construction BMPs and construction-related minimization measures to control dust, erosion, and runoff would minimize these effects. Any indirect impacts will be mitigated according to the requirements of the Carlsbad HMP (City of Carlsbad 2004). Special-Status Wildlife Most of the indirect impacts to vegetation communities and special-status plants cited previously can also affect special-status wildlife. In addition, wildlife may be indirectly affected in the short-term and long-term by noise, lighting, and an increased human presence. Noise impacts can have a variety of indirect impacts on wildlife species, including increased stress, weakened immune systems. altered foraging behavior, displacement due to startle, degraded communication with conspecifics (e.g., masking), damaged hearing from extremely loud noises, and increased vulnerability to predators {Lovich and Ennen 2011). Indirect impacts from construction-related noise may occur to sensitive wildlife if construction occurs during the breeding season (i.e., February 15 through September 1). Measures that limit noise levels and require pre-construction surveys for breeding birds during breeding season would ensure no impacts to nesting birds occurred as a result of construction noise. Lighting will be provided around the proposed project. All lights will be shielded downward and away from the upland buffer to avoid spillage at night into the conserved area. Shielded foot lighting will be provided along any recreational trails. Human activity within the study area has the potential to facilitate the presence and spread of non-native animal species, such as the brown-headed cowbird or Argentine ant(Linepithema humile). These species can cause habitat degradation, outcompete native species for food, displace native prey species, and decrease the nest productivity and viab1l1ty of offspring. An increased human presence also results in an increased incidence of vehicle strikes that could occur. Project design features shall be put 1n place to reduce these impacts to below significance. Wildlife Corridors and Habitat Linkages Indirect impacts to habitat linkages/wildlife corridors may occur during construction and post-construction activities. BMPs and measures, such as fencing and directing lighting away from open space areas, would minimize indirect impacts to habitat linkages and wildlife corridors. DUDEI< 19 9012 January 2019 Ms. Gay/ Hynek Subject: Biological Resources Letter Report and Impacts Analysis, Hynek Property, City of Carlsbad, San Diego County, California 6 Mitigation Measures Mit1gat1on measures are proposed for potential impacts resulting from implementation of the proposed project. The mit1gat1on measures will mitigate for potential impacts to sensitive habitat, special-status plant and wildlife species, and nesting birds protected under the Migratory Bird Treaty Act. These mitigation measures will reduce identified and potential significant impacts to a level that is less than s1grnf1cant, pursuant to CEQA. 6.1 Vegetation Communities and Land Covers Impacts to vegetation communities will be mitigated according to the ratios and requirements outlined in the Carlsbad HMP (City of Carlsbad 2004), which require permanent impacts to coastal sage scrub habitats to be mitigated at a 2:1 ratio (8.26 acres). Because the coastal sage scrub within the study area is occupied by gnatcatcher, at least 67% {10.18 acres) of the total coastal sage scrub must be conserved. LMFZ 8 Standards require that at least 75% of the site be preserved. Further, because the proposed project is within the Coastal Zone, mitigation must include a 1:1 creation {or substantial restoration) component to satisfy the no-net loss habitat standard, and on-site preservation cannot be counted toward this mitigation requirement. Therefore, the Carlsbad HMP would require 10.18 acres of coastal sage scrub habitat to be conserved on site, along with 8.26 acres of off-site preservation (including a minimum 4.13-acre creation/substantial restoration component), to mitigate for impacts to approximately 4.13 acres of coastal sage scrub habitat. No other sensitive habitats requiring mItIgatIon would be impacted as a result of the proposed proJect. Typically, impacts to non-native vegetation communities or land cover types require payment of an in-lieu mitigation fee. However, because more than 67% of the habitat within the property is bemg conserved, no fee Is required (City of Carlsbad 2008). The project retains 10.43 acres of Diegan coastal sage scrub, which exceeds the required 67% presetvation when California gnatcatcher is present. Additional mitigation measures to mitigate for indirect impacts to vegetation communities include the following: 1. Final habitat restoration plans shall be submitted to the City of Carlsbad and regulatory agencies for review at least 30 days prior to project initiation (See Appendix E ~ Proposed Onsite and Offsite Habitat Restoration). 2. All site preparation and construction actIvItIes should incorporate standard BMPs, including, but not limited to, straw bales, gravel bags, sand bags, the periodic watering of bare areas, and the dIrectIon of construction area drainage to existing storm drain facilities. 3. During construction, material stockpiles shall be placed such that they cause minimal interference with on- site drainage patterns. Silt fencing and other silt containment devices will be installed, where necessary, to prevent off-site transport of sediment and pollutants. 4. Prior to initiating grading/earth movement activItIes, all preserved habitats immediately adjacent to the work limits will be marked with temporary fencing and other appropriate markers clearly visible to construction personnel. No construction access, parking, or storage of equipment or materials will be permitted in such marked areas: staging areas will be located in disturbed habitat to the extent feasible. DUDEK 20 9012 January 2019 Ms. Gay/ Hynek Subject: Biological Resources Letter Report and Impacts Analysis, Hynek Property, City of Carlsbad, San Diego County, California 5. Equipment storage, fueling, and staging areas shall be located on disturbed upland sites with minimal risk of direct drainage into sensitive habitats. These designated areas shall be located in such a manner as to prevent any runoff from entering sensitive habitat. All necessary precautions shall be taken to prevent the release of cement or other toxic substances into surface waters. All project-related spills of hazardous materials shall be reported to the City and shall be cleaned up immediately, and contaminated soils shall be removed to approved disposal areas. 6. No plant species listed as problematic and/or invasive by the California Invasive Plant Council (formerly the California Exotic Pest Plant Council) or State of California shall be employed or allowed to naturalize or persist on the site. No plant species listed as a ··noxious weed" by the State of California or federal government shall be used in the property. 7. A qualified project biologist shall review grading plans (e.g., all access routes and staging areas) and monitor construction activities throughout the duration of the proposed project to ensure that all practicable measures are being employed to avoid incidental disturbance of habitat and any target species of concern outside the project footprint. 8. Construction monitoring reports summarizing how the project is in compliance with applicable conditions shall be completed and provided to the City. The project biologist should be empowered to halt work activity if necessary and to confer with City staff to ensure the proper implementation of species and habitat protection measures. 9. Any habitat destroyed that 1s not in the identified proJect footprint shall be disclosed immediately to the City, USFWS, and CDFW, and shall be compensated at a minimum ratio of 5:1. 10. Access to and from the site will be located along existing access routes or disturbed areas to the greatest extent possible. All access routes outside of existing roads or construction areas will be clearly marked. 11. Construction employees will limit their act1v1ties, vehicles, equipment, and construction materials to the fenced project footprint. 12. Equipment storage, fueling, and staging areas shall be located on disturbed upland sites with minimal risk of direct drainage into riparian areas or other sensitive habitats, and at least 100 feet from Waters of the United States. These designated areas shall be located in such a manner as to prevent any runoff from entering sensitive habitat. Al! necessary precautions shall be taken to prevent the release of cement or other toxic substances into surface waters. All project related spills of hazardous materials shall be reported to the City and shall be cleaned up immediately, and contaminated soils shall be removed to approved disposal areas. 13. Upon project completion, signage should be included in the sensitive habitat areas, where determined appropriate, for the purpose of identifying adJacent habitats and educating residents on the importance of staying on designated trails/paths, disposing trash properly, and reducing fire hazards. 14. All mitigation sites shall be conserved through fee title acquisition or Conservation Easement, as defined in California Civil Code Section 815.1, and proof of recordat1on shall be provided to the Jurisdictional city prior to land disturbance. DUDEI< 21 9012 January 2019 Ms, Gay/ Hynek Subject: Biological Resources Letter Report and Impacts Analysis, Hynek Property, City of Carlsbad, San Diego County, California 6.2 Special-Status Plant Species Potential impacts to special-status plant species would be mitigated by many of the same measures that apply to sensitive vegetation communities and land covers. Additionally, the following measure will mitigate any potential impacts to special-status plants occurring w1th1n the impact footprint: 1. A water pollution and erosion control plan that describes sediment and hazardous materials control, dewatering or diversion structures, fueling and equipment management practices, and other factors deemed necessary by reviewing agencies shall be developed. Erosion control measures shall be monitored on a regularly scheduled basis, particularly during times of heavy rainfall. Corrective measures will be implemented in the event erosion control strategies are inadequate. Sediment/erosion control measures will be continued at the project site until such time as the revegetation efforts are successful at soil stabilization. Avoidance of any impacts to Nuttall's scrub oak will be ensured by the following measure: 1. The footprint of disturbance shall be minimized to the maximum extent feasible and shall be specified in the construction plans. Construction limits will be delineated with orange fencing, which will be maintained until the completion of all construction activities. All employees shall be instructed that their activities, vehicles, equipment, and construction materials are restricted to the proposed project footprint, designated staging areas, and routes of travel. 6 3 Special-Status Wildlife Species Impacts to coastal California gnatcatcher habitats will be mitigated in accordance with the Carlsbad HMP, which requires habitat replacement at a ratio of 2:1 for gnatcatcher-occup1ed sage scrub. In add1t1on to this and other measures presented previously, measures to avoid direct and indirect impacts to special-status wildlife species include the following: 1. L1ght1ng in or adjacent to the conserved area will not be used, except where essential for roadway, facility use, and safety. If nighttime construction lights are necessary, all lighting adJacent to natural habitat will be shielded and/or directed away from habitat. 2. To avoid attracting predators of the target species of concern, the project site shall be kept as clean of debris as possible. All food-related trash items shall be enclosed in sealed containers and regularly removed from the site. Pets of project personnel shall not be allowed on site where they may come into contact with any listed species. 3. A qualified biologist shall conduct a training session for all project personnel prior to proposed activities. At a minimum, the training shall include a description of the target species of concern and its habitats, the general provisions of FESA and the Carlsbad HMP, the need to adhere to the provisions of the act and the Carlsbad HMP, the penalties associated with violating the provisions of the act, the general measures that are being implemented to conserve the target species of concern as they relate to the project, access routes, and project site boundaries within which the project activities must be accomplished. DUDEI< 22 9012 Januaiy 2019 Ms. Gay/ Hynek Subject: Biological Resources Letter Report and Impacts Analysis, Hynek Property, City of Carlsbad, San Diego County, California 4. The monitoring biologist shall be on site during any initial clearing of habitat (annual ground cover, shrubs, or trees}. The monitoring biologist will flush sensitive species (avian or other mobile species} from occupied habitat areas immediately prior to brush-clearing and earth-moving activities. 5. If dead or injured listed species are located, initial notification must be made within 3 working days, in writing, to the USFWS Division of Law Enforcement in Torrance, California, and by telephone and in writing to the applicable JurisdIctIon, the Carlsbad Field Office of USFWS. and CDFW. 6. Exotic species that prey on or displace target species of concern should be permanently removed from the site. 7. 1n order to avrnd impacts to nesting birds, clearing and grubbing activ1t1es are generally prohibited during the bird breeding season (February 15-September 15). USFWS will be notified at least 7 days before clearing and grubbing begins. During this activity, a qualified biologist will walk the area ahead of construction equipment to flush birds away from impact areas. The biologist will immediately report the number and location of any federally listed birds disturbed by clearing and grubbing to USFWS. No gnatcatchers will be injured or killed. Other construction activities will also be avoided during the breeding season, if feasible. If this cannot be avoided, the following measures will be taken: • A qual1f1ed biologist will conduct a focused species gnatcatcher survey in appropriate habitat within and surrounding the project area. The surveys will consist of three visits, 1 week apart; the last of these will be conducted no more than 3 days pnor to construction. • Surveys will also be conducted by a qualified biologist in appropriate habitat for nesting raptors and migratory birds and within an additional 500-foot survey buffer within 3 days of construction. • USFWS will be notified immediately of any federally listed species that are located during pre- construction surveys. • If nests of listed birds, migratory birds, raptors, or other sensitive species are located, they will be fenced with a protective buffer of at least 500 feet from active nests of listed species and of at least 300 feet from nests of other sensItIve bird species. All construction activity will be prohibited within this area. 8. During the breeding season (March through September), construction noise will be measured regularly to maintain a threshold at or below 60-decibel (dBA) hourly equivalent level over a given time period (leq) within 500 feet of breeding habitat occupied by listed species. If noise levels supersede the threshold, the construction array will be changed or noise attenuation measures will be implemented. Other measures discussed in Section 6.1, Vegetation Communities and Land Covers, of this report would further reduce potential adverse indirect impacts to special-status wildlife during construction. 64 Wildlife Corridors and Habitat Linkages Implementation of the proposed project is not expected to result in direct impacts to any wildlife corridors. Measures to mitigate direct permanent and temporary impacts. as well as indirect short-and long-term impacts discussed previously, would adequately reduce potential adverse effects on habitat linkages and wildlife corridors. DUDEI< 23 9012 January 2019 Ms. Gay/ Hynek Subject: Biological Resources Letter Report and Impacts Analysis, Hynek Property, City of Carlsbad, San Diego County, California 6.5 HMP Adjacency Standards The following HMP Adjacency Standards, as listed in HMP Section F pages F-16 to F-24, have been met through project design or will be met through cond1t1ons of approval: • Fuel management 1s limited to w1th1n the development footprint and does not extend in proposed on-site HMP Preserve open space. • Fuel modification areas are positioned to avoid sensitive biological resources, at the toe of the development slopes: no existing fire breaks occur 1n the area. • Erosion control measures are incorporated to avoid surface drainage within or near the Preserve. • Native plants used for required restoration/revegetation will be obtained from local genetic stock. • Irrigation runoff will be prevented from entering the Preserve. • S1gnage and fencing have been incorporated into the design consistent with the HMP Adjacency Standards. Rear perimeter residential fences. located at the top of the graded slope, consist of 1-2 feet of concrete block wall topped with metal fence with a maximum total height of 6 feet. An additional 3-wire fence is located at the toe of slope (i.e., edge of upland buffer) and open space signage will be placed every 100-feet. • lighting adjacent to the preserve will be reduced and/or shielded. • No proposed land uses are expected to general excessive noise within the Preserve. • Public outreach wrll be incorporated into the project, including information on potential adverse effects of invasive species used in landscaping, overuse of pesticides and fert1l1zers, and unleashed pets and pet waste. 7 Proposed Habitat Mitigation M1t1gation to meet Carlsbad HMP requirements for creation/substantial restoration and off-site preservation are detailed in Appendix E. In summary, proposed habitat restoration would occur at three sites: • On-Site Ocean View Pointe, • Off-Site Emerald Pointe Preserve • Off-Site Shorepointe Preserve, and • Off-site Batiqu1tos Lagoon Preserve Habitat restoration at these four sites will provide 8.66 acres of mitigation to meet the minimum 8.30-acre mitigation requirement for the proposed Ocean View Pointe project. The add1t1onal 0.36 acre is included as a contingency m case there are changes that occur during implementation or monitoring. The Ocean View Pointe preserve will be added the City of Carlsbad Habitat Management Plan (HMP) Preserve as part of the project, which includes preparing and funding a long-term Preserve Management Plan (PMP). The Shorepointe preserve area is already within the Carlsbad HMP Preserve but lacks a PMP or funding. The proposed mitigation would include preparing and funding a long-term PMP for the restoration treatment areas within the Shoreprnnte preserve. The Emerald Pointe preserve 1s already within the Carlsbad HMP Preserve and has a funded PMP; however. the proposed restoration area at Emerald Pointe is not funded for long-term management. The proposed mitigation would include a provision for additional funding for long-term management of the restoration treatment area. The Batiqu1tos Lagoon preserve area is partially with the Carlsbad HMP Preserve.

Areas with less than 10% cover of non-natfve invasive species are not included in the acreage calculations. Ocean View Pointe The Ocean View Pointe preserve consists of 16.7 acres of mostly coastal sage scrub (CSS) habitat proposed to be added to the Carlsbad HMP Preserve as part of the proJect. Areas within the proposed Ocean View Pointe preserve proposed for CSS Restoration consist of non-vegetated segments of dirt roads and/or trails, with a minor presence of Maltese star thistle and brome grasses scattered along the margins. Ocean View Point vegetation communities proposed for Enhancement include a mix of CSS of varying levels of disturbance, ranging between 10 and 20 percent composition of non-native plant species (see attached map set and photos}. The site is crossed by a variety of dirt roads/ trails. Native species dominating the CSS on site include: California buckwheat (Eriogonum fascicu/atum), California sagebrush (Artemisia californica), lemonade berry (Rhus integrifolia), California bush sunflower (Encelia californica), and clustered tarweed (Deinandra fasciculata). Non-native plant species most abundant on site are: mustards (Brassica spp.), various brome grasses (Bromus spp.) and Maltese star thistle (Centaurea me/itensis). 20 Percent Enhancement area contains lemonade berry, California sagebrush and California buckwheat. There is an area that appears to have been cleared in the past, and has colonized over time by primarily non-native species such as mustards, brome grasses and Maltese star thistle. Clustered tarweed is also scattered throughout the disturbance areas. 10 Percent Enhancement area contains lemonade berry, California sagebrush and California buckwheat. Substantial patches of mustards have outcompeted portions of the CSS where lower stature native species are present, such as Galiforn1a buckwheat and Cal1forn1a sagebrush. Additional areas in the proposed preserve area support approximately 5% cover of non-native invasive species. These areas will be treated but are not included in the pro~sed mitigation acreages because of the relative small area of habitat enhancement these treatments would achieve. DUDEI< 2 January 2019 Memorandum Subject: Ocean View Pointe -Proposed Onsite and Offsite Habitat Restoration See attached map for the location of proposed restoration areas: photos of the site are shown 1n the attached photo pages. Emerald Pointe The Emerald Pointe preserve consists of 10.1 acres of mostly CSS habitat located in the Carlsbad HMP Preserve. The property 1s owned and managed by the San Diego Habitat Conservancy consistent with an approved PMP. One contiguous polygon is proposed for Restoration within the Emerald Pointe preserve. This area consists of a nearly monotyp1c stand of mustard, which appears to be mowed semi-regularly. The Restoration polygon is adjacent the development buffer to the southeast, and a pre-existing CSS mitigation site to the northwest. A point of connection for irrigation appears to likely be available based on the presence of landscaping and temporary above-ground irrigation components. Emerald Pointe vegetation communities proposed for Enhancement include a mix of coastal sage scrub (CSS) with approximately 10 percent composition of non-native plant species (see attached map). The site has a dirt road utility easement, and a pre-existing mitigation site on the property. Native species dominating the CSS on site include: California buckwheat, California sagebrush, lemonade berry, clustered tarweed and sawtoothed golden bush (Hazardia squarrosa) in lesser numbers. Non-native plant species most abundant throughout site are: mustards, various brome grasses, Maltese star thistle and Russian thistle (Kali tragus). See attached map for the location of proposed restoration areas; photos of the site are shown in the attached photo pages. Shorepointe The Shorepomte preserve consists of 21.6 acres of mostly CSS habitat located in the Carlsbad HMP Hard(ine Preserve. The property is owned by the Carlsbad Shorepo1nte Homeowners Association. Historic descriptions of vegetation communities and vegetation mapping were reviewed (Biological Resources Assessment of the Roesch Site, Located in the City of Carlsbad, County of San Diego, California (Natural Resource Consultants, December 8, 1998). A field review was conducted of the parcel m the sprrng and summer of 2017 to evaluate the current condition and level of disturbance of the vegetation communities. Areas were mapped for either Restoration or Enhancement, with an approximate percentage of non-native and/ or disturbed area for Enhancement areas, as shown in the attached map set. Three large polygons are 1dent1fied for Restoration, with the smaller polygons through the drainage area of the site consisting primarily of individual occurrences of Pampas grass or tree tobacco. The large Restoration polygon at the far western side of the site consists of a highly disturbed area dominated by mustards, with star thistles and non-native grasses in lesser numbers. Native cover by CSS species is extremely sparse. The northernmost of the three main Restoration polygons consists primarily of mustards and Italian thistle (Carduus pycnocepha/us), with a sparse scattering of native CSS species. The central Restoration polygon consists of a mix of non-native grasses, herbaceous natives, and a few native grasses. Sparse occurrences by native CSS species are present. especially around the margins. Since the 1998 biological resources report describes native grasslands on site, the current mitigation approach and forthcoming conceptual m1t1gat1on plan would take into account presence of such native resources. DUDEI< 3 .Januaty 2019 Memorandum Subject: Ocean View Pointe -Proposed Onsite and Offsite Habitat Restoration 50 Percent Enhancement area is a polygon which is approximately 50 percent California sagebrush, and 50 percent non- native plant species such as mustard, Maltese star thistle and brome grasses. It is surrounded on the western side by primarily lemonade berry, and on the other penmeters by CSS, dominated by coyote brush (Baccharis pilularis). 15 Percent Enhancement areas consist primarily of the fall-lines of the valley floor, containing a drainage that runs generally east-west, originating upslope at the eastern end of the basin, and another drainage that runs generally south to north on the western side of the main access road. The 15 percent Enhancement areas also include the transitional uplands adjacent the drainages and their associated riparian vegetation. Dominant native vegetation within the drainages and associated riparian zone includes arroyo willow {Salix lasiolepis) and mulefat (Baccharis salicifo/ia). In the wettest areas associated with the channels, rushes were observed (Juncus spp.). In the transitional zones adjacent the riparian corridor, dominant species include giant wild rye (Elymus condensatus) and coyote brush. Non-native species within these areas to be controlled include Pampas grass (Cortaderia selloana}, tree tobacco (Nicotiana gtauca) and some giant reed (Arundo donax) along the western drainage. Upland weeds in associated with the transitional areas through these zones include non--native grasses, Maltese star thistle and mustards. 10 Percent Enhancement area is dominated by lemonade berry, California sagebrush, black sage (Sa/via me/lifera) California bush sunflower (Encelia ca/ifornica) and California buckwheat. Mustards, star thistles and non-native grasses have outcompeted portions of the CSS where lower stature native species are present. such as California buckwheat and California sagebrush. Additional areas in the proposed preserve area support approximately 5% cover of non-native invasive species. These areas will be treated but are not included in the proposed mitigation acreages because of the relative small area of habitat enhancement these treatments would achieve. See attached map for the location of proposed restoration areas; photos of the site are shown in the attached photo pages. Batiquitos Lagoon The Bat1qu1tos Lagoon preserve area consists of 20.8 acres of mostly CSS and wetland habitats. Approximately 11.6 acres of the property 1s within the Carlsbad HMP Preserve and 9.2 acres is outside the Preserve but considered conserved because the property is owned by the Batiqu1tos Lagoon Foundation. Areas proposed for Restoration are disturbed habitat or coastal sage scrub with at least 80% disturbance. The significantly disturbed coastal sage scrub areas contain a preponderance of black mustard, Maltese thistle, pampas grass, with lesser occurrences of Sydney golden wattle (Acacia /atifolia}, African sumac (Searsia /ancea), gum trees (Eucalyptus sp.) and tree tobacco. The Bat1quitos Lagoon vegetation communities proposed for Enhancement include a mix of coastal sage scrub (CSS) with levels of disturbance ranging between 10 and 50 percent. Native species prevalent within the CSS onsite include: coastal goldenbush (/socoma menziesii), California sagebrush, coyote bush, California buckwheat, California bush sunflower (Encelia califomica), coast cholla (Cylindropuntia prolifera), coast prickly pear (Opuntia littoralis), lemonade berry, and Mojave yucca (Yucca schidigera). Bladderpod (Cleome arborea) and California boxthorn (Lycium californ/cum) occur in lesser numbers. Non-native plant species most abundant within the CSS habitat include the following: mustards (Brassica spp.) Maltese star thistle, and pampas grass. Sweet fennel (Foenicu/um vu/gare), tree tobacco (Nicotiana g/auca) and other herbaceous annual weeds are also present in lesser numbers.
