The proposed project could result in a significant impact on sensitive habitats including Diegan coastal sage scrub, non-native grassland, and eucalyptus woodland and on nesting birds. However, it is anticipated that incorporation of mitigation measures outlined in Section 5 would avoid significant impacts on these resources. The-project site is within the City's HMP area. The project site is not within or adjacent to an existing or proposed hardline or standards area as defined in the City's HMP and is not within the Coastal Zone. The Project site does not support state and/or federally listed plants, animals, or jurisdictional wetlands or other Waters of the U.S. 2 Introduction The project site is located at 2200 Afton Way in the City and is bordered by Carlsbad Village Drive on the north and residential housing on the east, south, and west. There is an existing home and associated outbuildings on the 3.79-acre site that are no longer occupied or used. The proposed project consists of razing the existing structures, clearing of vegetation, grading, and construction of nine single-family homes on 10,000 square-foot minimum lots. 3 METHODS AND SURVEY LIMITATIONS This study included the following activities: • Review of City Guidelines for Biological Studies (2008) and HMP (2004) • General biological survey and vegetation mapping • Analysis of potential project impacts on biological resources • Analysis of project conformance with local, state, and federal biological regulations Rocks Biological Consulting (RBC) began preparations for surveys by creating field maps using Geographic Information System (GIS) and incorporating relevant data including a color aerial photograph and the California Department of Fish and Wildlife's (CDFW) California Natural Diversity Database (CNDDB) information for the U.S. Geological Society 7.5' San Luis Rey Quadrangle. The CNDDB information was used to assess the potential for sensitive species to occur within or immediately adjacent the project site. On September 10, 2014 RBC mapped vegetation communities/land uses within the project site to provide a baseline of the biological resources that occur or have the potential to occur. Vegetation mapping was conducted by walking the project site and classifying habitats based on the dominant and characteristic plant species in accordance with Holland's Preliminary Descriptions of the Terrestrial Natural Communities of California (Holland 1986), as modified by Oberbauer in Draft Vegetation Communities of San Diego County (Oberbauer et al. 2008). The vegetation and land uses were mapped on an aerial photograph at 1 :2400 scale (1 inch= 200 ROCKS BIOLOGICAL CONSUL TING 1 in = 2.5 miles City of Carlsbad HMP -Existing Hardline -Proposed Hardline Standards Area -Outside-Conserved Source.

The extent of each habitat type (delineated as a habitat polygon on the compiled vegetation map) was calculated using GIS. Representative photographs of the project site were taken and are included as Appendix A. General biological surveys and/or habitat assessments for plants and animals were conducted during the vegetation mapping effort and included a reconnaissance survey for off-site wetlands, riparian habitat, oak woodland, nesting raptors, and/or narrow endemic species located within 100-feet of the property. Plant species observed during the field survey were identified and recorded in field notebooks. Plant names follow the Checklist of the Vascular Plants of San Diego County, 5th edition (Rebman and Simpson 2014); a list of the vascular plant species observed within the project site is presented in Appendix B. Wildlife species were detected during the field survey by sight, calls, tracks, scat, or other signs, and were recorded in field notebooks. Binoculars (8X42 magnification) were used to aid in the identification of wildlife. In addition to species observed during the surveys, expected wildlife use of the BSA was determined by known habitat preferences of local species and knowledge of their biogeographic distribution in the region. Scientific and common names of animals follow American Ornithologists' Union (AOU 2014) for birds, Wilson and Reeder (2005) for mammals, and Crothers (2014) for reptiles and amphibians. A list of wildlife species observed within or adjacent the project site is presented in Appendix B. The project site was also assessed for the presence of potential wetlands and/or jurisdictional streambeds, but no formal jurisdictional delineation per U.S. Army Corps of Engineers was conducted. The field survey was conducted under clear skies, calm winds, and warm weather (77 °F). Due to the late season timing of the survey, faunal activity at the time was low and early spring annual plant species were not observable. However, summer flowering species and evergreen perennial species were documented. No focused surveys for rare, threatened, or endangered plant or wildlife species were conducted. 4 RESULTS 4.1 Physical Setting The approximately 3.79-acre project site is located on moderately sloping to flat ground near the terminus of Afton Way. The site consists primarily of residential development and associated ornamental plantings, including large patches of eucalyptus woodland. The surrounding land use is dense residential housing with associated local roads. 4.2 Vegetation Communities and Land Uses A total of five vegetation communities or land uses were identified within the project site as shown in Table 1. The spatial distribution of each vegetation community and land use is presented on the Biological Resources Map (Figure 3). ROCKS BIOLOGICAL CONSUL TING 5 ,,..,.,,, 2200 AFTON WAY PROJECT BIOLOGICAL ~OURCES TECHNICAL REPORT Table 1. Vegetation Communities and Land Uses Vegetation Community Acreage Diegan coastal sage scrub -disturbed 0.18 Non-native grassland 1.27 Ornamental 1.22 Eucalyptus woodland 0.91 Urban/Developed 0.22 Total 3.79 Diegan Coastal Sage Scrub -Disturbed Diegan coastal sage scrub is comprised of low growing, aromatic, drought deciduous, soft- woody shrubs to about four feet high, many of which are facultatively drought-deciduous. The Diegan subtype of coastal sage scrub consists of California sagebrush (Artemisia californica), California buckwheat (Eriogonum fasciculatum), laurel sumac (Malosma laurina), lemonadeberry (Rhus integrifolia), and black and white sage (Salvia mellifera and S. apiana). This collection of species is typically found on dry, south-facing slopes or clay-rich soils that are slow to release stored water. Within the project site, the Diegan coastal sage scrub has been degraded by previous clearing or ground disturbance likely associated with the previous residential use of the property. The small patch still present is located near the northern boundary of the site and consists of an over story of eucalyptus woodland in most areas further reducing its habitat value. The Diegan coastal sage scrub -disturbed onsite is not suitable for the federally-listed threatened coastal California gnatcatcher (Polioptila californica californica) because of its small size, highly degraded condition, and isolation from other patches of suitable Diegan coastal sage scrub offsite. Eucalyptus Woodland Eucalyptus woodland is typically characterized by dense stands of gum trees (Eucalyptus spp.) that are native to Australia. Eucalyptus trees were originally planted in groves throughout many regions of coastal California as a source of lumber, as windbreaks, and as a horticultural novelty. Eucalyptus trees have increased their cover through natural regeneration, particularly in moist areas sheltered from strong coastal winds. Within the project site, eucalyptus trees occur primarily in dense groves with a barren understory or sparse non-native grassland. Although a non-native species, eucalyptus trees provide some wildlife habitat value as they have the potential to support nesting birds including raptor species because of their height and dense canopy. Non-Native Grassland Non-native grassland consists of a dense to sparse cover of annual grasses, often with native and non-native annual forbs (Holland 1986). This habitat generally occurs on fine-textured loam or clay soils that are moist to waterlogged during the winter rainy season, and very dry during the summer and fall. This habitat is a disturbance-related community most often found in old fields or ROCKS BIOLOGICAL CONSUL TING 6 C """"'' """" 2200 AFTON WAY PROJECT BIOLOGICAL RESOURCES TECHNICAL REPORT openings within native scrub habitats. This association has replaced native grassland and coastal sage scrub at many localities throughout southern California. The non-native grassland within the project site is comprised primarily of ripgut brome (Bromus diandrus), slender wild oat (Avena barbata), and purple false-brome (Brachypodium distachyon). Some broad-leaved forbs such as Russian thistle (Sa/so/a tragus), and short-pod mustard (Hirschfeldia incana) are also present. Ornamental Ornamental vegetation typically consists of non-native landscape and/or garden species that are planted in association with buildings, roads, and developments or have escaped cultivation and occur within native habitats. San Diego County supports a wide variety of ornamental trees and shrubs, as well as herbs that decorate urban areas. Ornamental vegetation within the project site is primarily associated with the house and adjacent yard. Species present include Cape leadwort (Plumbago auriculata), Italian stone pine (Pinus pinea), mousehole tree (Myoporum /aetum), golden wattle (Acacia longifolia), eucalyptus, hottentot fig (Carpobrotus edu/is), and desert carpet (Acacia redo/ens). Urban/Developed Urban/developed areas within the project site support no native vegetation and are comprised of human-made structures such as buildings and roads. The level of soil disturbance is so high that only ruderal plant species can persist. The developed areas onsite include the existing house, outbuildings, and paved driveway and Afton Way. 4.3 Flora The project site supports a low diversity of vegetation types and plant species due to the developed and disturbed nature of the site. In addition, observations of annual plant species were likely low due to the late season timing of the field survey. Most of the floral diversity onsite is due to the large number of ornamental plantings associated with the residential landscaping. No sensitive plant species, including City narrow endemic species, were observed or have the potential to occur onsite. A list of plant species observed during the field survey is included as Appendix B. 4. 4 Wildlife The project site supports a low diversity of wildlife due to the urban setting of the site, the developed and degraded nature of the vegetation communities, and isolation from large vegetated open space areas. In addition, observations of wildlife species were likely low due to the late season timing of the field survey. Also, a nighttime survey was not conducted so nocturnal animals were not documented. No sensitive wildlife species, including City Narrow Endemic Species, were observed or have the potential to occur onsite. A list of wildlife species observed during the field survey is included as Appendix B. 4.5 Sensitive Species and Habitats Sensitive biological resources are those defined as follows: 1) Species that have been given special recognition by federal, state, or local conservation agencies and organizations due to ROCKS BIOLOGICAL CONSUL TING 7 .....,, 2200 AFTON WAY PROJECT BIOLOGICAL RESOURCES TECHNICAL REPORT limited, declining, or threatened/endangered population sizes; 2) Species and habitat types recognized by local and regional resource agencies as sensitive; 3) Habitat areas or vegetation communities that are unique, are of relatively limited distribution, or are of particular value to wildlife; 4) Wildlife corridors and habitat linkages; and/or 5) Biological resources that may or may not be considered sensitive, but are regulated under local, state, and/or federal laws. For the purposes of this report, species are considered to be sensitive if they meet one or more of the following criteria: • Listed under the federal or state Endangered Species Act (CDFW 2014; USFWS 2014). • City of Carlsbad HMP Covered Species (2004) • USFWS Birds of Conservation Concern (USFWS 2014) • CDFW Special Animals List (CDFW 2011) • CDFW Species of Special Concern (CDFW 2014). • CDFW Fully Protected Species (CDFW 2014). • Covered as a state protected furbearing mammal (California Code of Regulations [14 CCR Section 460]). • Listed as having a California Rare Plant Rank (CRPR; formerly CNPS List, CNPS 2014). No sensitive plant or animal species were observed and none are expected due to the developed and disturbed nature of the project site. 4.6 Jurisdictional Wetlands The project site does not support jurisdictional wetlands or other Waters of the U.S. or state such as intermittent or ephemeral streambeds. A concrete-lined brow ditch is present along the northern and eastern boundaries of the site. These features are not jurisdictional because they were constructed in upland areas for the purpose of conveying storm water runoff and do not represent or replace a naturally occurring streambed or other wetland area. 4.7 Wildlife Movement Corridors A wildlife corridor can be defined as a link of wildlife habitat, usually consisting of native vegetation that joins two or more larger areas of similar wildlife habitat. Corridors are critical for the maintenance of ecological processes including allowing for the movement of animals and the continuation of viable populations. Corridors enable migration, colonization and interbreeding of plants and animals. Corridors can consist of large, linear stretches of connected habitat (such as riparian vegetation) or as a sequence of stepping-stones across the landscape (discontinuous areas of habitat such as wetlands and ornamental vegetation), or corridors can be larger habitat areas with known or likely importance to local fauna. Regional corridors are defined as those linking two or more large patches of habitat, and local corridors are defined as those allowing resident animals to access critical resources (food, cover, and water) in a smaller area that might otherwise be isolated by urban development. The project site does not function as a wildlife corridor because it is surrounded on all sides by dense residential development. The nearest sizable open space habitats are associated with ROCKS BIOLOGICAL CONSUL TING 8 """"' 2200 AFTON WAY PROJECT BIOLOGICAL ~OURCES TECHNICAL REPORT Buena Vista Creek and Lagoon to the north and west that are approximately 0.6 to 1 mile from the project site. There is no continuous connection or corridor between the project site and these open space areas. The project site is not included as a Core or Linkage area under the City's HMP. 5 PROJECT IMPACTS This section describes the proposed project's potential direct, indirect, and/or cumulative impacts on sensitive biological resources that could occur with implementation of the proposed project. The following thresholds of significance have been used to determine whether project implementation would result in a significant direct, indirect, and/or cumulative impact. These thresholds are based on Appendix G of the state CEQA Guidelines (CCR Title 14, Division 6, Chapter 3, Sections 15000-15387). A significant biological resources impact would occur if the project would: • Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by CDFW or USFWS; • Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, or regulations or by CDFW or USFWS; • Have a substantial adverse effect on federal protected wetlands as defined by Section 404 of the Clean Water Act (CWA) (including, but not limited to, marshes, vernal pools, and coastal areas) or any state-protected jurisdictional areas not subject to regulation under Section 404 of the CWA through direct removal, filling, hydrological interruption, or other means; • Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites; • Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy, or ordinance; • Conflict with the provisions of an adopted habitat conservation plan; natural community conservation plan; or other approved local, regional, or state habitat conservation plan; or • Substantially reduce the habitat of a fish or wildlife species; cause a fish or wildlife population to drop below self-sustaining levels; threaten to eliminate a plant or animal community; or substantially reduce the number or restrict the range of an endangered, rare, or threatened species. 5.1 Direct impacts Direct impacts include actions that result in removal or disturbance of sensitive habitat; incidental take of sensitive species; and degradation of habitats due to construction-related activities. Direct project impacts were quantified by overlaying the project plan or 'footprint' on the Biological ROCKS BIOLOGICAL CONSUL TING 9 ,-., '-:) 2200 AFTON WAY PROJECT BIOLOGICAL RESOURCES TECHNICAL REPORT Resources Map (Figure 3). Direct impacts on habitats or land uses are listed in Table 2 and shown on Figure 3. Table 2. Proposed Project Impacts on Vegetation Communities and Land Uses Existing Proposed Vegetation Community Acreage Impact Acreage Diegan coastal sage scrub -disturbed 0.18 0.18 Non-native grassland 1.27 1.20 Ornamental 1.22 1.03 Eucalyptus Woodland 0.91 0.88 Urban/Developed 0.22 0.22 Total 3.79 3.50 Permanent direct impacts on Diegan coastal sage scrub, non-native grassland, and eucalyptus woodland are considered potentially significant under the City's Guidelines for Biological Studies and HMP and would require mitigation to offset the impact. Impacts on ornamental and urban/developed areas onsite are not considered significant and would not require mitigation. Habitats within the project site have the potential to support nests that would be protected under the Migratory Bird Treaty Act and/or the California Fish and Game Code (§3503) under which it is unlawful to "take, possess, or needlessly destroy" avian nests or eggs. Thus potential direct impacts could occur if vegetation clearing is undertaken during the breeding season (February 15 -September 15). There would be no significant impacts on sensitive species including HMP Covered Species as none are present onsite. There would be no significant impacts on wildlife movement as the project site does not serve as a local or regional wildlife corridor. 5.2 Indirect impacts Indirect impacts include short-term impacts that may occur during construction, such as sediment or other discharges that could impact water quality; noise impacts; lighting impacts; increase in human activity during construction; and project operations. The project would entail demolition of existing structures, earthwork, and single-family home construction activities with the potential to generate dust and noise. Ground disturbance during construction also has the potential to result in accelerated erosion. However, the project will incorporate measures to address and reduce these types of impacts, including implementation of standard dust control measures and compliance with City residential noise regulations. With these in place, and given the temporary nature of dust and noise-generating activities, construction dust and noise are not anticipated to result in significant impacts on biological resources. In addition, the project will require a Stormwater Pollution Prevention Plan (SWPPP), which will include measures to control erosion during and following construction. With the SWPPP in place, significant impacts associated with accelerated erosion of disturbed ground are not expected. ROCKS BIOLOGICAL CONSUL TING 10 -~,"""'i'-, ~ 2200 AFTON WAY PROJECT BIOLOGICAL RESOURCES TECHNICAL REPORT 5.3 Cumulative impacts Cumulative impacts include both the potential regional (long-term, additive) effects of a project and the ways a project, in combination with other projects and conditions in a region, may affect an ecosystem or one of its components beyond the project limits and on a regional scale. Because the project would be consistent with the City of Carlsbad's HMP, a regional conservation plan, there would be no cumulatively significant biological impacts. 6 MITIGATION MEASURES This section describes the mitigation measures that, if implemented, would reduce the proposed project's potential direct, indirect, and/or cumulative impacts on sensitive biological resources to below the level of significant. 6.1 Habitat Mitigation Under the City's Guidelines for Biological Studies (2008), project impacts on sensitive HMP habitats must be mitigated. Project mitigation must occur at ratios outlined in Table 3, which also itemizes the proposed impacts on each habitat type and the resulting mitigation requirement. Pursuant to City regulations, mitigation for impacts on HMP habitats may be achieved by conserving lands on or off-site, or through payment of in lieu fees to the City's HMP. As shown in Table 3, the City currently charges a per acre fee based on the habitat group and type. Project impacts on Diegan coastal sage scrub -disturbed, non-native grassland, and eucalyptus woodland can be mitigated by payment of the in-lieu fee. Lands designated as urban/developed and ornamental are not considered to have significant habitat value and would not require mitigation. With the payment of in lieu fees the project will provide adequate mitigation for impacted habitats. Table 3. Summary of Mitigation Fees for Impacts on HMP Habitats Impact HMP Mitigation Ratio HMP Habitat Group and Type Acreage and In Lieu Fee In Lieu Fees 1: 1 D. Unoccupied coastal sage scrub 0.18 $30,626/acre $5,512.68 E. Annual (non-native grassland) 0.5:1 1.20 $15,313/acre $9,187.80 Mitigation Fee F. Eucalyptus 0.88 $3,063/acre $2,695.44 Ornamental 1.03 ---- Urban/Developed 0.22 ---- Total 3.50 --$17,395.92 Note: Mitigation ratios and fees per City of Carlsbad's development fee schedule (September 1, 2014) 6.2 Nesting Bird Mitigation Within the City's HMP area, clearing and grubbing activities are generally prohibited during the bird breeding season (February 15 -September 15) to avoid direct impacts on raptors and/or native/migratory birds. If construction activities cannot be avoided during the breeding season, a ROCKS BIOLOGICAL CONSUL TING 11 ~· "'""\ '-"' -.,I 2200 AFTON WAY PROJECT BIOLOGICAL RESOURCES TECHNICAL REPORT qualified biologist shall conduct a pre-construction (precon) survey to determine the presence or absence of nesting birds within the proposed impact area and an additional 500-foot survey buffer within three days of construction (including removal of vegetation). If nests of listed birds, migratory birds, raptors, or other sensitive species are located they will be fenced with a buffer of at least 500 feet of active nests of listed species and 300 feet from other sensitive bird species. All construction activity will be prohibited within this area. If nesting birds are not observed during the precon survey, no further mitigation is required. 7 DISCUSSION The project site is not within or adjacent to an existing or proposed hardline or standards area as defined in the City's HMP and is not within the Coastal Zone. The project site does not support state and/or federally listed plants, animals, or jurisdictional wetlands or other Waters of the U.S. or state. The site does not support City Narrow Endemic or Covered Species. The proposed project could result in a significant impact on habitats including Diegan coastal sage scrub, non-native grassland, and eucalyptus woodland and on nesting birds. However, through incorporation of the mitigation measures outlined in Section 5, impacts would be reduced to below a level of significance. In addition to the mitigation requirements listed above, the project will require a Carlsbad HMP Permit and must comply with the Standard Impact Mitigation Measures listed in Appendix A in the City's Guidelines for Biological Studies. These guidelines provide project design, pre- construction, and construction related mitigation measures that should be addressed before and during project implementation.
