Technical Report for the Martin Residence Project 8093ivJanuary 2017 INTENTIONALLY LEFT BLANK DUDEK Biological Technical Report for the Martin Residence Project 8093v January 2017 SUMMARY OF FINDINGS A general biological reconnaissance survey was conducted at the Martin Residence project in the City of Carlsbad (City) on November 27, 2013. Three vegetation communities or land covers were identified on site: disturbed habitat, beach, estuarine. An additional two vegetation communities or land covers were identified within 100 feet of the project site: Diegan coastal sage scrub (coastal form) and urban/developed land. ACOE, RWQCB, and CCC jurisdiction of tidal wetlands extends to 18 inches above mean ordinary high tide elevation on site or to the 3.5- foot contour. Two special-status plant species were recorded, southwestern spiny rush and woolly seablite, but no special-status wildlife species were observed during the survey. No direct impacts to special-status vegetation, plants, or wildlife, as well as jurisdictional resources (including a 100-foot buffer), are expected to occur with implementation of project avoidance and minimization measures. In addition, no direct impacts to an existing hardline preserve are expected to occur. Mitigation and avoidance measures are provided for potential indirect impacts to biological resources and to comply with the City’s Habitat Management Plan (HMP). DUDEK Biological Technical Report for the Martin Residence Project 8093viJanuary 2017 INTENTIONALLY LEFT BLANK DUDEK Biological Technical Report for the Martin Residence Project 80931 January 2017 1.0 INTRODUCTION 1.1 Purpose of the Report This biological technical report (BTR) summarizes the results of biological studies conducted on the Martin Residence project site to describe the existing conditions of the biological resources on the project site, including on-site vegetation, jurisdictional resources, flora, wildlife, potential for special-status species, and wildlife movement. The biological significance of these resources and potential project impacts are evaluated and measures are recommended to avoid, minimize, or mitigate potential impacts where feasible to less-than-significant levels. 1.2 Project Location The Martin Residence project site is located in the northwestern portion of the City of Carlsbad (see Figure 1, Regional Map). The site lies within the U.S. Geological Survey (USGS) 7.5- minute map San Luis Rey Quadrangle: Section 8, Township 12 South, Range 4 West; principal meridian: San Bernardino; latitude N 33°8'41.445"; and longitude W 117°19'36.928" (see Figure 2, Vicinity Map). Specifically, the project site is located immediately south of Adams Street and north of Agua Hedionda Lagoon. The approximately 0.47-acre project site is currently undeveloped, but has been graded in the past. It is relatively flat with elevation at approximately 0 to 64 feet above mean sea level (amsl). 1.3 Project Description The project proposes to construct an approximately 4,085 square-foot single-family residence with a 850 square-foot garage. Approximately 0.22 acre of the project site along Agua Hediona Lagoon will not be constructed; however, native landscaping is proposed in this area. Access to the project site would be from Adams Street. The site is designated Residential Low-Medium Density (RLM), 0-4 dwelling units per acre, with a Growth Management Control Point of 3.2 dwelling units per acre in the City of Carlsbad General Plan and Residential Single-family, 15,000 square-foot minimum lot size (R-1-15,000) per the City’s Municipal Zoning Code. The project site is located within the California Coastal Zone and would be subject to the requirements of the California Coastal Act as implemented by the City of Carlsbad through their approved local coastal programs (LCPs). DUDEK Biological Technical Report for the Martin Residence Project 80932 January 2017 1.4 Regulatory Context 1.4.1 North County Multiple Habitat Conservation Program The North County Multiple Habitat Conservation Program (MHCP) is a long-term regional conservation plan established to protect sensitive species and habitats in northern San Diego County. The MHCP is divided into seven Subarea Plans—one for each jurisdiction within the MHCP—that are permitted and implemented separately from one another. The City of Carlsbad is the only city under the MHCP that has an approved and permitted Subarea Plan (i.e., the City of Carlsbad Habitat Management Plan). The HMP includes Adjacency Standards by which apply to apply to properties that are adjacent to conserved habitat areas, such as the existing hardline preserve at Agua Hedionda Lagoon at the southern end of the project site. The standards address issues of fire management, erosion control, landscaping, fencing, signage, lighting, and non-native species control (see F-16 through F-24 of the HMP). In addition, the Conditions for Estuarine Species are applicable to the proposed project since the project is located adjacent to a lagoon (City of Carlsbad 2004, 2009). Carlsbad Municipal Code Section 21.210.040(9) The Carlsbad Municipal Code’s Habitat preservation requirements state: All development projects located in the coastal zone shall also be required to comply with the additional, general conservation standards contained in Section D.7, Standards 7-1 through 7-12 of the HMP and the additional, parcel-specific conservation standards contained in Section D.7, Standards 7-13 and 7-14 of the HMP as incorporated into the local coastal program. Standards 7-13 and 7-14 do not apply to this project, but Standards 7-1 through 7-12 provide guidance related to protection of the following: Environmental Sensitive Habitat Areas (ESHAs), coastal sage scrub, oak woodland, streams, ephemeral drainages and ephemeral streams, wetlands, wetland mitigation requirements, no net loss of habitat (i.e., Coastal Sage Scrub, Maritime Succulent Scrub, Southern Maritime Chaparral, Southern Mixed Chaparral, Native Grassland, and Oak Woodland), upland habitat mitigation requirements, highly constrained properties, buffers and fuel modification zones (see Wetland Buffers section below), and grading and landscaping requirements. Standard 7-6 specifies that wetlands in the Coastal Zone be delineated following the definitions and boundary descriptions in Section 13577 of the California Code of Regulations, which requires a 100-foot landward measurement from the upland limit of the wetland. In addition, Standard 7-6 refers to the California Public Resources Code Section 30233, which states that no DUDEK Biological Technical Report for the Martin Residence Project 80933 January 2017 impacts to wetlands shall be allowed in the Coastal Zone except as projected in that Section. Where there are impacts to wetlands, mitigation shall be provided at a ratio of 3:l for riparian impacts and 4:l for saltwater or freshwater wetland or marsh impacts.

Wetland buffer areas establish an upland zone adjacent to wetlands designed to avoid and minimize indirect effects on wetland functions (e.g., species habitat, water quality maintenance, flood capacity). Several documents establish guidelines for wetland buffers that would be applicable to this project, including: City of Carlsbad LCP has provisions that state: Buffers shall be provided between all preserved habitat areas and development. Minimum buffer widths shall be provided as follows: a. 100 feet for wetlands b. 50 feet for riparian areas c. 20 feet for all other native habitats (coastal sage scrub, southern maritime chaparral, maritime succulent scrub, southern mixed chaparral, native grassland, oak woodland). Buffer widths shall be measured from the edge of preserved habitat nearest the development to the closest point of development…Any proposed reductions in buffer widths for a specific site shall require sufficient information to determine that a buffer of lesser width will protect the identified resources. Such information shall include, but is not limited to, the size and type of the development and/or proposed mitigation (such as planting of vegetation or the construction of fencing) that will also achieve the purposes of the buffer. The California Department of Fish and Game, the U.S. Fish and Wildlife Service, and the Coastal Commission staff shall be consulted in such buffer determinations. HMP Permit 1.4.2 California Coastal Act The project is located within the boundaries of the coastal zone within a coastal deferred certification area. Under the California Coastal Act (CCA), the California Coastal Commission (CCC) regulates the “coastal zone” and requires a coastal development permit for almost all development within this zone. The CCA also protects designated sensitive coastal areas by providing additional review and approvals for proposed actions in these areas. 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, DUDEK Biological Technical Report for the Martin Residence Project 80939 January 2017 mudflats, and fens” (California Public Resources Code, Section 30121). The CCA allows diking, 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 an LCP for CCC certification (California Public Resources Code, Section 30500). 1.4.3 Agua Hedionda Land Use Plan and Local Coastal Program Agua Hedionda Lagoon and surrounding properties are also regulated by the City’s Agua Hedionda Land Use Plan and Local Coastal Program (LCP) (City of Carlsbad 1982). The LCP identifies the lagoon as supporting water quality, viewshed, public use, and biological values that require protection. The lagoon is designated as a pre-existing natural open space hardline preserve (Figure 2). DUDEK Biological Technical Report for the Martin Residence Project 809310 January 2017 2.0 METHODS AND SURVEY LIMITATIONS A general biological reconnaissance survey was conducted by Dudek biologists Kathleen Dayton and Patricia Schuyler on November 26, 2013 (8:00–9:30 am; 57–63 degrees Fahrenheit; 80%– 95% cloud cover; 0–2 mile per hour winds). This survey included vegetation mapping, a jurisdictional delineation, and habitat assessment for special-status plant and wildlife species. 2.1 Literature Review A review of existing biological resource information for the project site was conducted to provide baseline information regarding special-status biological resources potentially occurring on the site and in the surrounding area. The following sources were reviewed for pertinent information prior to conducting the baseline biological diversity surveys: California Natural Diversity Database (CNDDB) information provided by CDFW (2013), CNPS’s Inventory of Rare and Endangered Vascular Plants (CNPS 2013), the U.S. Fish and Wildlife Service (USFWS)’s species occurrence database (USFWS 2013), MSHCP species occurrences (SANDAG 2010), and the San Diego Plant Atlas (SDNHM 2013). 2.2 Vegetation Mapping Vegetation communities and land covers were mapped in the field directly onto 100-scale (1 inch = 100 feet) base maps of the project area using color aerial imagery overlaid with 2-foot topographic contours. Vegetation surveys were conducted throughout the site on foot. Following the completion of fieldwork, vegetation polygons were digitized using ArcGIS and geographic information system (GIS) coverage was created. Acreage calculations of vegetation communities and land covers were determined using ArcGIS. Vegetation community classifications used in this report follow Holland (1986), as revised by Oberbauer et al. (2008). Vegetation mapping was conducted in November 2013 by Dudek biologists Kathleen Dayton and Patricia Schuyler. The jurisdictional delineation was conducted concurrently with vegetation mapping. 2.3 Jurisdictional Delineation A jurisdictional delineation was conducted within the project boundary to delineate areas under the jurisdiction of the CDFW, pursuant to Sections 1600–1603 of the California Fish and Game Code, under the jurisdiction of the U.S. Army Corps of Engineers (ACOE), pursuant to Section 404 of the federal Clean Water Act (CWA), under jurisdiction of Regional Water Quality Control Board (RWQCB), pursuant to CWA Section 401 and the Porter-Cologne Act, and under the jurisdiction of the CCC under the CCA. The ACOE jurisdictional wetlands delineation was conducted in accordance with the U.S. Army Corps of Engineers Wetland Delineation Manual (ACOE 1987), the Interim Regional Supplement to the Corps of Engineers Wetland Delineation DUDEK Biological Technical Report for the Martin Residence Project 809311 January 2017 Manual: Arid West Region (ACOE 2008), and Rapanos Guidance (ACOE and EPA 2007); hydrology, vegetation, and soils were examined at potential wetland sites and were recorded on wetland determination data forms. A predominance of hydrophytic vegetation, where associated with a stream channel, was used to define CDFW-regulated riparian vegetation. The limits of areas under the jurisdiction of the RWQCB generally match those areas delineated as ACOE-jurisdictional. However, stream channels with evidence of an ordinary high water mark (OHWM) that lack connectivity to “waters of the U.S.” may be considered to be under the jurisdiction of RWQCB and CDFW but not under the jurisdiction of ACOE. CCC jurisdiction was based on presence of any one of the three wetland criteria. ACOE jurisdiction of tidal wetlands, regardless of the presence/absence of indicators, extends to 18 inches above mean ordinary high tide elevation. Based on tide charts for the Carlsbad area, ordinary mean high tide was determined to be approximately 3 feet amsl, and therefore tidal wetlands jurisdiction extends to the 4.5-foot contour amsl (Anderson 2011). It is presumed that RWQCB and CCC also take jurisdiction over this tidal area. Additional wetlands jurisdiction may occur above the 4.5-foot contour, but would be based on presence of appropriate wetlands indicators. CDFW, under the Lake and Streambed Alteration program, does not regulate impacts to marine wetlands that are supported by tidal influences. The extent of wetland features was determined in the field by collecting data using a Global Positioning System (GPS) unit; the shapes were then transferred to topographic base, and GIS coverage was created. The results of the study include areas delineated as jurisdictional by the ACOE, RWQCB, and the CCC. Since the project area is solely influenced by tides, none of the wetlands on site is under the jurisdiction of the CDFW. 2.4 Special-Status Plants Sensitive biological resources present or potentially present were identified through a literature search using the following sources: CNDDB (CDFW 2013), the Inventory of Rare and Endangered Vascular Plants (CNPS 2013), the San Diego Plant Atlas (SDNHM 2013), the USFWS’s species occurrence database (USFWS 2011), and MSHCP species occurrences (SANDAG 2013). Special-status plant species considered in this report are those that are: (a) listed by federal and/or state agencies, proposed for listing as threatened or endangered, or are candidate species; (b) included in the CNPS inventory; or (c) listed species covered by the Carlsbad HMP (City of Carlsbad 2009). No focused surveys for special-status plant species have been conducted on site. However, a general reconnaissance survey was conducted to determine the potential for special-status plant species to occur on the project site. The potential for special-status plant species to occur on site was evaluated based on the elevation, soils, vegetation communities, and level of disturbance of the site, as well as DUDEK Biological Technical Report for the Martin Residence Project 809312 January 2017 their status and distribution in the vicinity of the project site. Table 1, Special-Status Plant Species Detected or Potentially Occurring on the Project Site, summarizes the results of this analysis.

Binoculars (10×40) were used to aid in the identification of observed wildlife. A cumulative list of wildlife species observed by Dudek during the reconnaissance survey is presented in Appendix B, Wildlife Species List. Latin and common names of animals follow American Ornithologists’Union (AOU) (2008). The potential for special-status wildlife species to occur on site was evaluated based on the elevation, vegetation communities, and level of disturbance of each site, as well as their status and distribution in the vicinity and the results of wildlife surveys conducted on site.

The timing of the surveys did not coincide with the blooming period for many annual plant species so presence or absence of species with suitable habitat could not be confirmed. In addition, no focused surveys for wildlife species were conducted on site. However, conditions were appropriate for the detection of species and performing habitat assessments for species. DUDEK Biological Technical Report for the Martin Residence Project 809341 January 2017 3.0 PHYSICAL CHARACTERISTICS 3.1 Environmental Setting The Project area is located in the in the northwestern portion of the City of Carlsbad immediately north of Agua Hedionda Lagoon, and east of Interstate 5 (see Figures 1 and 2). Land use in the project vicinity is primarily residential development although Agua Hedionda Lagoon lies to the south. The Encinas Power Plant occurs to the west and agricultural land occurs south of Agua Hedionda. Additional open space occurs to the east of the lagoon and extends to El Camino Real. 3.2 Topography The Project area generally has flat topography with an elevation of approximately 0 to 64 feet amsl. 3.3 Soils According to the Soil Survey of the San Diego Area, California (Bowman 1973), the only soil type identified within the project vicinity is Marina loamy coarse sand, 9% to 30% slopes. This soil type is formed in eolian sands derived from mixed sources and is somewhat excessively drained (Bowman 1973). Marina soils are slightly to strongly acid (USDA 2001). DUDEK Biological Technical Report for the Martin Residence Project 809342 January 2017 INTENTIONALLY LEFT BLANK DUDEK Biological Technical Report for the Martin Residence Project 809343 January 2017 4.0 RESULTS 4.1 Vegetation Mapping Three vegetation communities and land covers were mapped on the project site based on general physiognomy and species composition: disturbed habitat, beach, and estuarine. Two additional vegetation communities and land covers were mapped within the 100-foot buffer of the project site: Diegan coastal sage scrub and urban/developed land (see Table 3, Vegetation Communities and Land Covers). Vegetation communities considered sensitive by the Carlsbad HMP include those listed in Habitat Groups A through E. Figure 3, Biological Resources, shows the distribution of vegetation communities and land covers on the project site. Table 3 Vegetation Communities and Land Covers Vegetation Community/Land Cover Habitat Group1 Acres on Site Acres within 100 feet of the Site Non-Natural Land Covers Disturbed Habitat F 0.36 0.52 Urban/Developed NA —0.79 Non-Natural Land Covers Subtotal 0.36 1.31 Unvegetated Habitat Beach B 0.06 0.21 Estuarine A 0.05 0.60 Unvegetated Subtotal 0.11 0.81 Upland Scrub Diegan Coastal Sage Scrub D —0.18 Upland Scrub Subtotal —0.18 Total 0.47 2.29 1 Habitat Groups and the Mitigation Ratios for Impacts to HMP Habitats are listed in Table 3 of the Guidelines for Biological Studies (City of Carlsbad 2008). 4.1.1 Disturbed Habitat (11300) Disturbed habitat refers to areas that are not developed yet lack vegetation, and generally are the result of severe or repeated mechanical perturbation. Disturbed habitat is a Habitat Group F vegetation community in the Carlsbad HMP, indicating that it has limited habitat value. Disturbed habitat on site occurs throughout the majority of the site and is either lacks vegetation or is composed of ruderal, non-native species. There are some scattered and mostly immature coastal sage scrub or marsh species with low cover. The site is characterized primarily by disturbed habitat as a result of previously permitted grading. I I I I I I DUDEK Biological Technical Report for the Martin Residence Project 809344 January 2017 4.1.2 Urban/Developed (12000) Developed land consists of buildings, structures, homes, parking lots, paved roads, and maintained areas. Developed areas do not support native vegetation. Urban/developed land is not included in a Habitat Group in the Carlsbad HMP, indicating that it has little to no habitat value. Urban/developed land is located off site and is associated with the residences on either side of the proposed project and with Adams St. to the north. 4.1.3 Diegan Coastal Sage Scrub: Coastal Form (32510) Coastal sage scrub is a native plant community composed of a variety of soft, low, aromatic shrubs, characteristically dominated by drought-deciduous species such as California sagebrush (Artemisia californica), flat-top buckwheat (Eriogonum fasciculatum), and sages (Salvia spp.); with scattered evergreen shrubs, including lemonadeberry (Rhus integrifolia), laurel sumac (Malosma laurina), and toyon (Heteromeles arbutifolia). Below 1,000 feet amsl, Diegan coastal sage scrub develops as the coastal form, which typically includes more California sagebrush than inland forms (Oberbauer et al. 2008). Diegan coastal sage scrub typically develops on south- facing slopes and other xeric situations. Diegan coastal sage scrub is in Habitat Group D of the Carlsbad HMP since it is unoccupied by coastal California gnatcatcher; mitigation would be required for impacts to this habitat. The Diegan coastal sage scrub occurs off site north of Adams Street. It is strongly dominated by laurel sumac with few other species. 4.1.4 Estuarine (64130) Estuarine habitats include periodically and permanently flooded areas and open water portions of semi-enclosed coastal waters where tidal seawater mixes with flowing fresh water. Estuarine habitats generally have high species richness, but low species diversity because of the variation in salinity and depth (Oberbauer et al. 2008). Estuarine is in Habitat Group A of the Carlsbad HMP; mitigation would be required for impacts to this habitat. Estuarine can be regulated by CDFW pursuant to Section 1600 of the California Fish and Game Code, the RWQCB pursuant to Section 401 of the federal CWA and the Porter-Cologne Act, and ACOE pursuant to Section 404 of the federal CWA. Agua Hedionda Lagoon makes up the estuarine habitat on site. The site is located on the northern shore of the lagoon.

Ocean beaches are a shoreline feature of deposited sand formed by waves and tides off the coast. Lake beaches may form from waves, disturbance, or geological formations Beaches are generally Unvegetated, but sometimes the upper portions may have a low cover of herbaceous species. Beach is in Habitat Group B of the Carlsbad HMP; mitigation would be required for impacts to this habitat. On site, beach includes the sandy portion north of the estuarine habitat of the Agua Hedionda Lagoon. 4.2 Inventory of Plants and Wildlife A total of 40 vascular plant species, including 26 native species (65%) and 14 non-native species (35%) were recorded during the surveys (Appendix A). A total of seven bird species were detected in the study area during the reconnaissance survey of the site (Appendix B). 4.3 Special-Status Plants Two special-status plant species were identified during the biological reconnaissance survey conducted in November 2013. Both species are CRPR 4.2 species, indicating they are watch list species with a limited distribution that are moderately threatened in California. Southwestern spiny rush is a perennial rhizomatous herb that blooms March through June and grows in mesic coastal dunes, alkaline seeps, and coastal salt marshes and swamps (CNPS 2013). One individual occurs in the southern portion of the project site and two immature individuals occur just off site (Figure 3). Woolly seablite is a perennial evergreen shrub that blooms January to December and generally occurs on coastal bluff scrub, coastal dunes, and the margins of coastal salt marshes and swamps (CNPS 2013). Two woolly seablite individuals were observed in the southeastern portion of the site (Figure 3). Table 2 lists special-status plant species reported in the USGS 7.5 minute San Luis Rey quad and the surrounding seven topographic quadrangles, as well as species covered under the Carlsbad HMP, and their potential to occur on site based on habitat associations, preferred soil substrate, life form, and blooming period. 4.4 Special-Status Wildlife No special-status wildlife species were observed during the general biological reconnaissance survey conducted in November 2013. Special-status species having the potential to occur within the project study area, based on the presence of suitable habitat and/or distribution, are listed in Table 3. Table 3 includes special-status wildlife species reported in the USGS 7.5 minute San Luis Rey quad and the surrounding seven topographic DUDEK Biological Technical Report for the Martin Residence Project 809348 January 2017 quadrangles (CDFW 2013; SANDAG 2013; USFWS 2013), as well as species covered under the Carlsbad HMP, and their potential to occur on site based on the location of the site and general vegetation communities found in the area. Where pertinent, a distinction is made between foraging and breeding habitat available on site. 4.5 Special-Status Vegetation Two special-status vegetation communities were recorded on site: estuarine and beach. One special-status vegetation community was recorded off site: Diegan coastal sage scrub (see Table 3). 4.6 Jurisdictional Delineation The jurisdictional determinations provided in this report are considered preliminary; final determinations would require completion of significant nexus analysis and confirmation with the wetlands resource agencies staff. The preliminary determinations are provided to determine the maximum extent of potential jurisdictional areas and, therefore, define the area of necessary impact avoidance to avoid any requirement for wetlands permits. Three agencies (ACOE, RWQCB, and CCC) have jurisdiction up to 18 inches above mean ordinary high tide elevation, regardless of whether the lands within that area support any of the three wetland criteria (vegetation, soils, and hydrology). Based on the results of the jurisdictional delineation, there were no other areas above this jurisdictional line that would have met the wetland definition of supporting all three wetland criteria: hydrology, soils, and vegetation. CDFW, under its Lake and Streambed program, does not regulate marine environments and wetlands mainly supported by tidal conditions. The shoreline and wetlands within the project area are marine environments supported by tidal conditions and therefore not regulated by CDFW. There is a total of 0.09 acre of ACOE/RWQCB non-wetland waters and CCC tidelands on site (Table 4).

DUDEK Biological Technical Report for the Martin Residence Project 809349 January 2017 4.7 Wildlife Movement Corridors Wildlife movement is restricted through the site considering the Interstate 5 (I-5) occurs west of the site and Adams Street occurs to the north. There is also chain-link fencing along the northern boundary of the site and fencing around neighboring homes. Wildlife movement may be permitted along the lagoon shoreline along the southern boundary of the site and through the lagoon. To the east, the lagoon leads to the Agua Hediona Lagoon CDFW Ecological Reserve on the north shore. The lagoon also leads to an established private and City-owned preserve east of the lagoon (Figure 2). The lagoon leads to the Pacific Ocean after crossing under the I-5, the railroad tracks, and Carlsbad Boulevard to the west. DUDEK Biological Technical Report for the Martin Residence Project 809350 January 2017 INTENTIONALLY LEFT BLANK DUDEK Biological Technical Report for the Martin Residence Project 809351 January 2017 5.0 EVALUATION OF PROJECT IMPACTS This section addresses direct and indirect to biological resources that would result from implementation of the proposed project. Direct impacts result from the direct removal or conversion of an area’s biological resources (e.g., through grading associated with development or other ground disturbance activities). Direct impacts can be both temporary and permanent. Direct impacts to vegetation communities were quantified by overlaying the proposed impact limits on the biological resources map of the study area. For special-status wildlife species, impacts to suitable primary habitat were quantified in the same manner. For the proposed project, the impact limits were determined by the development footprint. All biological resources within the impact limits were considered directly, permanently impacted except for temporary impacts associated with an constructing a connection with an existing sewer line at the existing cleanout. Indirect impacts result primarily from adverse edge effects, and may be short-term in nature, related to construction, or long-term in nature, associated with development in proximity to biological resources within natural open space. For the proposed project, it is assumed that the potential indirect impacts resulting from short-term construction activities include dust, noise, and general human presence that may temporarily disrupt species and habitat vitality, and construction-related soil erosion and runoff. With respect to these potential indirect impacts, however, all project grading will be subject to the typical restrictions (e.g., Best Management Practices) and requirements that address erosion and runoff, and may include the federal Clean Water Act, National Pollution Discharge Elimination System (NPDES), and preparation of a Stormwater Pollution Prevention Plan (SWPPP). Long-term indirect impacts associated with the proposed project may include noise, lighting, invasion by exotic plant and wildlife species, effects of toxic chemicals (e.g., fertilizers, pesticides, herbicides, and other hazardous materials) on the adjacent Agua Hedionda Lagoon, urban runoff from developed areas, soil erosion, litter, hydrological changes, and an increase in general human presence. Cumulative impacts refer to incremental individual environmental effects over the long-term implementation of the project when considered together with impacts from other projects in the area. These impacts taken individually may be minor but are collectively significant because they occur over a period of time. 5.1 Direct Impacts 5.1.1 Vegetation Communities Permanent direct impacts to vegetation communities are shown in Table 5, Direct Permanent Impacts to Vegetation Communities and Land Covers. Approximately 0.21 acre of the site would be impacted by the proposed project on site and 0.03 acre of off-site impacts would occur just DUDEK Biological Technical Report for the Martin Residence Project 809352 January 2017 north of the project site. All impacts are considered permanent impacts except for less than 0.01 acre of temporary impacts to disturbed habitat on site as a result of a sewer line connection. Figure 4, Impacts Map, illustrates the distribution of biological resources in the project study area and the locations where proposed impacts would occur.

The remaining impacts to disturbed habitat are permanent. 5.1.2 Special-Status Vegetation Communities Implementation of the proposed project will not result in direct impacts to any special-status vegetation communities (see Table 5). Because disturbed habitat and developed land provides little, if any, wildlife habitat value, the permanent loss of 0.24 acres of disturbed habitat and developed land is not a significant impact. However, impacts to disturbed habitat require an in lieu mitigation fee in an amount to be determined by the City Council (City of Carlsbad 2004, Table 11). 5.1.2.1 Jurisdictional Wetlands/Waters Implementation of the proposed project would not result in direct impacts to the ACOE/RWQCB non-wetland waters and CCC tidelands on site (Figure 4). In addition, less than 0.01 acre of the total project impacts occur within 100 feet of the jurisdictional resources on site. Therefore, direct impacts to jurisdictional wetlands/waters are not anticipated. I I I DUDEK Biological Technical Report for the Martin Residence Project 809353 January 2017 5.1.3 Special-status Plant Species No direct impacts to the special-status plants would occur from project construction. Both the southwestern spiny rush and woolly seablite are south of the project footprint. However, landscaping is proposed south of the project footprint on site in the area where southwestern spiny rush and woolly seablite occur. The landscaping plan will be designed to avoid these species to avoid direct impacts as described in Section 6.1.3.1, Special-Status Plants. All special- status plant species evaluated in Table 2 that have a moderate potential to occur would only have a moderate potential to occur in the southern portion of the site along Agua Hedionda Lagoon and outside of the proposed project footprint. Therefore, direct impacts to special-status plant species are not anticipated.

No special-status species that may potentially occur within these areas would be significantly impacted by the loss of 0.24 acre of disturbed habitat or developed area. Therefore, direct impacts to special-status wildlife are not anticipated. While no active or inactive nests were identified during the survey conducted in November 2013, there is a potential for birds to nest on site. In the event that work occurs during the breeding season (February 15 through September 1), nesting raptors and other nesting birds could be directly impacted by vegetation clearing activities. 5.1.5 Wildlife Corridors/Habitat Linkages The proposed project will avoid direct permanent impacts to Agua Hediona Lagoon and the beach above it. Because the project site likely facilitates terrestrial and avifauna wildlife movement through Agua Hediona Lagoon, these functions will not be permanently impacted by the project. Although wildlife movement may be disrupted temporarily during construction, these impacts are considered temporary in nature and implementation of the overall project will not result in permanent direct impacts to wildlife movement functions. Following construction, wildlife will continue to use the lagoon and shoreline to aid in movement to other areas of biological value. Therefore, direct, permanent impacts to wildlife corridors/habitat linkages are not anticipated. 5.2 Cumulative Impacts The majority of the site is characterized by disturbed habitat, and impacts to these areas would not result in any cumulative impacts to biological resources when considered in conjunction with other planned state, local, federal, and private projects in the project vicinity. The project avoids the Agua Hediona Lagoon. 5.3 Indirect Impacts Indirect impacts may result from (1) temporary, short-term effects due to construction activity; and (2) long-term effects from development. 5.3.1 Vegetation Communities/Special-status Vegetation Communities Indirect effects to vegetation communities in general primarily would result from adverse “edge effects.”During construction, short-term edge effects may include dust, soil erosion, and runoff that could disrupt plant vitality. However, all project grading will be subject to the implementation of Best Management Practices (BMPs) and typical restrictions and requirements that address dust control, erosion, and runoff, including the federal Clean Water Act and NPDES. No impacts over 0.01 acre are proposed within 100 feet of the wetlands/waters on site in order, DUDEK Biological Technical Report for the Martin Residence Project 809357 January 2017 which will minimize indirect effects to the Agua Hedionda Lagoon. Furthermore, development of the home is not expected to degrade water quality or cause changes in surface water or ground water as they will draw from the City water system. Runoff, erosion and sedimentation will be addressed through implementation of BMPs. Long-term indirect effects due to the increased use of adjacent roadways potentially include dispersal of trash and debris, potential for polluted runoff from the roadway, accidental and intentional fire ignitions, and invasion by exotic plants. Absent avoidance, minimization, and mitigation, these impacts are considered significant. 5.3.2 Special-status Plant Species Indirect effects to southwestern spiny rush and woolly seablite, like vegetation, may include dust, soil erosion, and runoff that could disrupt plant vitality. However, all project grading will be subject to the implementation of Best Management Practices (BMPs) and typical restrictions and requirements that address dust control, erosion, and runoff, including the federal Clean Water Act and NPDES. Absent avoidance, minimization, and mitigation, these impacts are considered significant. 5.3.3 Special-Status Wildlife Species Indirect impacts to vegetation communities cited above also apply to habitats for special-status wildlife species. Additional potential wildlife species-specific indirect impacts include noise, lighting, increased human presence on trails and paths, non-native species (e.g., cowbirds and Argentine ants), and increases in vehicle traffic on the improved roadway. Absent avoidance, minimization, and mitigation, these impacts are considered significant. Nesting birds can be significantly affected by short-term construction-related noise, resulting in decreased reproductive success or abandonment of an area as nesting habitat. Breeding passerine and raptor species may use some portions of the site for nest construction and foraging. 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). Indirect impacts to nesting birds resulting from construction noise would be considered significant absent mitigation. 5.3.4 Wildlife Corridors/Habitat Linkages Local wildlife movement would be subject to the same edge effects described above for special- status wildlife. The construction of a single residential unit could increase human presence, noise, and trash/debris near Agua Hediona Lagoon where movement would be expected to occur. The edges along the lagoon increase the likelihood of invasion by exotic species. Runoff and sedimentation may also indirectly impact the lagoon. This could result in long-term indirect impacts to existing wildlife movement. This would be considered a significant impact absent avoidance, minimization, and mitigation. DUDEK Biological Technical Report for the Martin Residence Project 809358 January 2017 6.0 RECOMMENDED AVOIDANCE AND MINIMIZATION MEASURES 6.1 Mitigation for Direct Impacts Impacts will be avoided, minimized, and mitigated to the greatest extent possible. Development will be limited to disturbed and developed areas. 6.1.1 Vegetation Communities Because there are no direct impacts to special-status vegetation communities (Habitat Groups A through E), no mitigation for impacts to these communities is proposed. However, the per-acre in-lieu mitigation fee is estimated to be $800 for disturbed habitat as a Habitat Group F habitat type. Therefore, approximately $176 will be provided as mitigation for permanent direct impacts to 0.22 acre of disturbed habitat. The fee will be determined by city council resolution and collected at issuance of Grading Permit (City of Carlsbad 2004). The fee is in lieu of providing on-site or off-site mitigation land and will be adjusted as necessary to acquire suitable habitat on a per acre basis comparable to the land being developed. The fee will be used to fund the acquisition of habitat land in the MHCP as required by the HMP and implementing agreement (Section 21.210.040 of the Zoning Ordinance). 6.1.2 Jurisdictional Resources Because there are no direct impacts to jurisdictional resources, no mitigation is proposed. However, the jurisdictional areas on site are regulated by ACOE, RWQCB, and/or CCC so they will be subject to the requirements imposed through these agencies. The project may be required to have a federal Clean Water Act, National Pollution Discharge Elimination System (NPDES), and preparation of a Stormwater Pollution Prevention Plan (SWPPP). These would need to be prepared to the standards of the appropriate wetland permitting agency and the City. 6.1.3 Special-Status Species 6.1.3.1 Special-Status Plants Direct impacts to southwestern spiny rush and woolly seablite will be avoided in the landscaping plan design. In addition, prior to implementation of the landscaping plan, a qualified biologist will flag or temporarily fence the southwestern spiny rush or woolly seablite on site to prevent any unintentional impacts to these species during implementation of the plan. 6.1.3.2 Special-Status Wildlife Direct impacts to special-status wildlife are not anticipated; therefore, no species-specific mitigation is necessary for direct impacts. To address potential impacts to nesting birds the DUDEK Biological Technical Report for the Martin Residence Project 809359 January 2017 following mitigation from the City’s guidelines (City of Carlsbad 2004, Section 8.1.3) will be implemented: Clearing and grubbing activities will be avoided during the bird breeding season (February 15 –September 15). The USFWS will be notified at least seven 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 to USFWS the number and location of any federally listed birds disturbed by clearing and grubbing. 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: x Surveys will be conducted by a qualified biologist in appropriate habitat for nesting raptors and migratory birds and within an additional 500-foot survey buffer within three days of construction. x The USFWS will be notified immediately of any federally listed species that are located during pre-construction surveys. x 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 300 feet from other sensitive bird species. All construction activity will be prohibited within this area. x During the breeding season, construction noise will be measured regularly to maintain a threshold at or below 60 dBA hourly 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. 6.1.4 Habitat Linkages/Wildlife Corridors No mitigation is proposed for direct impacts to habitat linkages/wildlife corridors because the proposed impacts are not considered significant. 6.2 Mitigation for Indirect Impacts 6.2.1 Vegetation Communities and Jurisdictional Resources The following mitigation measures to mitigate for indirect impacts to special-status vegetation communities and jurisdictional resources include the following: 1. To mitigate for indirect impacts to vegetation communities and jurisdictional resources, a buffer will be incorporated into the project to lessen adverse impacts at the development- DUDEK Biological Technical Report for the Martin Residence Project 809360 January 2017 open space interface. A 100-foot buffer will be established from the edge of jurisdictional resources associated with Agua Hedionda Lagoon. Buffers are intended to ensure the biological integrity and preservation of the wetland. The limits of this 100-foot wetland buffer will be staked and flagged to ensure that the project does not encroach upon it. 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. Fencing plans will describe the type and location of fencing, including (a) permanent fencing along any urban/wildlands interface to deter unauthorized access (if deemed necessary by the City), (b) permanent fencing to direct animals toward wildlife undercrossings and away from traffic, and (c) temporary fencing to delineate the construction footprint, impact zones within the footprint, protected areas, and no- construction buffer zones 5. Plans for landscaping adjacent to natural habitat will include the following stipulations: (1) No invasive exotic plant species (Lists A and B of the Cal-IPC exotics list) will be used in landscaping, (2) No plants that require excessive irrigation, fertilizers, or pesticides will be used in landscaping, and (3) Irrigation of landscaping within 200 feet of a hardline boundary will be controlled to prevent runoff into the preserve. 6. Plans for lighting, fencing, drainage, restoration and other activities that might directly or indirectly impact sensitive habitats or species; the plans will document compliance with Adjacency Standards, including the following: a. Since new development is proposed, fuel management will be incorporated within the development boundaries and cannot encroach into the preserve. b. Fuel reduction zones, fire breaks and access routes will be positioned to (1) avoid sensitive biological resources, (2) be located at the top or bottom of (not across) a slope, or (3) be located along existing fire breaks where available. c. Erosion control measures will be implemented to avoid new surface drainage or erosion within or near the preserve. d. The use of non-native or invasive plant species in landscaping for public projects adjacent to preserves will be prohibited. e. Native plants used for restoration or revegetation will be obtained from local genetic stock to avoid genetic contamination of native species. DUDEK Biological Technical Report for the Martin Residence Project 809361 January 2017 f. Irrigation runoff will be prevented from entering into the preserve from adjacent landscaping to reduce nitrogen, pesticides, and excess moisture. g. Signage and fencing will be used as necessary to prevent harmful or unauthorized use of the adjacent preserve, and to protect animals from road kill mortality. Fences that restrict animal movement across movement corridors and habitat linkages will be removed. h. Lighting adjacent to preserves will be reduced (low pressure sodium lighting) and/or shielded. i. The use of noise generating equipment will be avoided during the breeding season. Noise levels inside the preserve should not exceed 60 dBA Leq. 7. Since the project is adjacent to the Agua Hedionda Lagoon, it will adhere to the Conditions for Estuarine Species (MHCP Vol II, Appendix E): a. The project will not contribute to degraded water quality, changes in surface water or groundwater hydrology, or increased runoff, erosion, and sedimentation with implementation of the following BMPs: i. Regulatory measures, such as erosion control ordinances and floodplain restrictions ii. Structural measures, such as detention or retention basins, filters, weirs, check dams, or drainage diversions iii. Vegetative controls that reduce runoff volume and accomplish pollutant removal by a combination of filtration, sedimentation, and biological uptake iv. Maintenance of pump station and sewer lines and stormwater conveyance systems v. Cultural practices like restrictions on pesticide and fertilizer applications, storage or disposal of toxic chemicals, or washing of vehicles or equipment in areas that can drain to the estuary b. For clearing, grading, and other construction activities within the watershed, ensure that proper irrigation and stormwater runoff mitigation measures are employed to reduce sediment loads and to prevent contamination from pesticides, fertilizers, petroleum products, and other toxic substances. 6.2.2 Special-Status Species Although no focused surveys were conducted for special-status plants or wildlife, no focused surveys would be recommended given the high level of disturbance of the site and low suitability for special-status species. In addition, the following mitigation measures address impacts to potentially occurring special-status species. DUDEK Biological Technical Report for the Martin Residence Project 809362 January 2017 6.2.2.1 Special-Status Plants Indirect impacts on special-status plants, including southwestern spiny rush and woolly seablite, will be mitigated through implementation of the proposed avoidance and mitigation measures for vegetation communities and jurisdictional resources, discussed above. 62.3.2 Special-Status Wildlife Indirect impacts on potentially occurring special-status wildlife will be mitigated through implementation of the proposed avoidance and mitigation measures for vegetation communities and jurisdictional resources, discussed above, as well as the following. 1. A biological monitor will be on site during the initial clearing to assure that special-status species will not be directly impacted by brush-clearing and earth-moving equipment. The biological monitor will also perform a final check to verify that construction activities did not extend beyond the staked and fenced construction limits. 2. To avoid short-term indirect noise impacts on potentially occurring special-status wildlife, an avian nesting survey shall be performed per the City’s guidelines (see Section 7.1.3.2). 3. Since the project is adjacent to the Agua Hedionda Lagoon, it will adhere to the Conditions for Estuarine Species (SANDAG 2003, Appendix E): a. Restrict/limit recreational or other activities within 200 feet of important foraging, breeding, and roosting areas. b. Require attenuation measure for activities that generate noise levels greater than 60 dB if occurring within 200 feet of important breeding habitat during the breeding season. 6.3 Mitigation for Cumulative Impacts Cumulative effects on biological resources will be mitigated through implementation of the proposed avoidance and mitigation measures, discussed above. 6.4 HMP Compliance The proposed project requires an HMP permit per Section 21.210.020(A)(4) of the City of Carlsbad Code of Ordinances. This section constitutes an analysis of how this project complies with the requirements and standards of the HMP as required by HMP Permit submittal items (Item G). DUDEK Biological Technical Report for the Martin Residence Project 809363 January 2017 6.4.1 HMP Mitigation Requirements The HMP complies with the mitigation requirements contained in Table 11 of the HMP. As discussed in Section 6.1.1, project implementation will not result in direct impacts to Habitat Groups A through E. Approximately $176 will be provided as mitigation for permanent direct impacts to 0.22 acre of disturbed habitat based on the estimated per-acre in-lieu mitigation fee required for impacts to Habitat Group F habitat types. 6.4.2 Additional Preservation Conditions This project complies with the additional preservation conditions contained in Section 21.210.040D of the Zoning Ordinance as follows: 1. No narrow endemic species were identified in the project area and no narrow endemic species have a moderate or high potential to occur on site. Therefore, no impacts to narrow endemic species will occur with implementation of the proposed project. 2. As described in more detail in Section 6.1.3.2, the City’s guidelines (City of Carlsbad 2004, Section 8.1.3) will be implemented to address potential impacts to nesting birds. Clearing and grubbing activities during the bird breeding season (February 15 – September 15) will be avoided. 3. The project is designed to avoid all wetlands on the project site, including a 100-foot buffer of the wetlands. In addition, no special-status vegetation or suitable habitat for special-status plants and animals will be directly impacted with project implementation. The project also avoids Agua Hedionda Lagoon and the beach directly above it, thereby avoiding potential wildlife movement corridors. Therefore, the project is located and designed to minimize overall impacts to natural habitat. 4. All fuel modification (brush management) zones are located outside the preserve areas, and are considered within the permanent impact footprint analyzed in Section 5.1. 5. The project is designed to avoid all wetlands on the project site, including a 100-foot buffer of the wetlands. No riparian habitat occurs on site. 6. No vernal pools occur on site. 7. No coastal sage scrub occurs on site. There is some potentially suitable habitat for gnatcatcher to the west, but it is buffered from the site by a residence. The Diegan coastal sage scrub mapped off site north of Adams Street is dominated by laurel sumac, making it unsuitable gnatcatcher habitat. DUDEK Biological Technical Report for the Martin Residence Project 809364 January 2017 8. The project complies with all of the applicable standards of the MHCP. The following measures are adapted from the standard best management practices (SANDAG 2003, Appendix B) and will be implemented as part of this project: o 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 MHCP, the need to adhere to the provisions of the Act and the MHCP, the penalties associated with violating the provisions of the Act, the access routes to and project site boundaries within which the project activities must be accomplished. o A water pollution and erosion control plan shall be developed that describes sediment and hazardous materials control, dewatering or diversion structures, fueling and equipment management practices, and other factors deemed necessary by reviewing agencies. 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. o The footprint of disturbance shall be minimized to the maximum extent feasible. Access to sites shall be via pre-existing access routes to the greatest extent possible. o Projects should be designed to avoid the placement of equipment and personnel on the beach of Agua Hedionda lagoon. o Projects that cannot be conducted without placing equipment or personnel in sensitive habitats should be timed to avoid the breeding season of the target species of concern. o Equipment storage, fueling, and staging areas shall be located on upland sites with minimal risks of direct drainage into Agua Hedionda Lagoon. 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 appropriate entities including, but not limited to, the City of Carlsbad, USFWS, CDFW, and State Water Resources Control Board (SWQCB) and shall be cleaned up immediately and contaminated soils removed to approved disposal areas. DUDEK Biological Technical Report for the Martin Residence Project 809365 January 2017 o Erodible fill material shall not be deposited into Agua Hedionda Lagoon. Brush, loose soils, or other similar debris material shall not be stockpiled on the beach of the lagoon. o The qualified project biologist shall monitor construction activities throughout the duration of the project to ensure that all practicable measures are being employed to avoid incidental disturbance of habitat outside the project footprint. Construction monitoring reports shall be completed and provided to the City of Carlsbad, USFWS, and the CDFW summarizing how the project is in compliance with applicable conditions. The project biologist will have the authority to halt work activity if necessary and to confer with staff from the City of Carlsbad, USFWS, and CDFW to ensure the proper implementation of species and habitat protection measures. o All food related trash items shall be enclosed in sealed containers and regularly removed from the site(s). Pets of project personnel shall not be allowed on-site where they may come into contact with any listed species. o Construction employees shall strictly limit their activities, vehicles, equipment, and construction materials to the proposed project footprint and designated staging areas and routes of travel. The construction area(s) are the minimal area necessary to complete the project and are specified in the construction plans. Construction limits will be fenced with orange snow screen. Exclusion fencing will be maintained until the completion of all construction activities. All employees will be instructed that their activities are restricted to the construction areas. o Any habitat destroyed that is not in the identified project footprint shall be disclosed immediately to the City of Carlsbad, USFWS, and CDFW and shall be compensated at a minimum ratio of 5:1. o If dead or injured listed species are located, initial notification must be made within three working days, in writing, to the Service’s Division of Law Enforcement in Torrance, California and by telephone and in writing to the applicable jurisdiction, Carlsbad Field Office of the USFWS, and CDFW. o The City of Carlsbad will have the right to access and inspect any sites of approved projects for compliance with project approval conditions including these BMPs. The USFWS and CDFW may accompany City representatives on this inspection. DUDEK Biological Technical Report for the Martin Residence Project 809366 January 2017 o Any planting stock to be brought onto the site for landscaping or ecological restoration shall first be inspected by a qualified pest inspector to ensure it is free of pest species that could invade natural areas, including but not limited to Argentine ants, fire ants, and other insect pests. Any planting stock found to be infested with such pests shall not be allowed on the project site or within 300 feet of natural habitats. The stock shall be quarantined, treated, or disposed of according to best management principles by qualified experts in a manner that precludes invasions into natural habitats. The project is consistent with measures to minimize impacts to covered species described in Section D.6, Table 9, and Appendix C of the HMP. The project would not affect lands occupied by narrow endemic species. Therefore, conservation standards described for narrow endemic species in Section D.6 would not apply to this project. The project would mitigate for impacts to disturbed habitat based on the mitigation requirements provided in Table 11 of the HMP as described in Section 6.1.1. Species-specific measures for species described in Section D.6 of the HMP would not apply to this project because suitable habitat for least Bell’s vireo, southwestern willow flycatcher, and Harbison’s dun skipper butterfly would not be impacted. Measures for HMP Species listed in Table 9 of the HMP and in Appendix C would also not apply since no covered species were observed or are expected to occur on site. 9. Since this project is located in the coastal zone it will comply with the additional, general conservation standards contained in Section D.7, Standards 7-1 through 7-12 of the where applicable as described below. The additional, parcel-specific conservation standards contained in Section D.7, Standards 7-13 and 7-14 of the HMP do not apply for this project. x 7-1: Pursuant to Section 30240 of the California Coastal Act, environmentally sensitive habitat areas (ESHA), as defined in Section 30107.5 of the Coastal Act, shall be protected against any significant disruption of habitat values, and only uses dependent on those resources shall be allowed within those areas. On site, the beach, estuarine, and jurisdictional areas may constitute ESHA and no direct impacts will occur to this area of the project site or to the 100-foot buffer of the jurisdictional area. x 7-2: No coastal sage scrub occurs on site. The coastal sage scrub off site will not be impacted. x 7-3: No oak woodlands occur on site. x 7-4: No streams occur on site. x 7-5: No ephemeral drainages or ephemeral streams occur on site. DUDEK Biological Technical Report for the Martin Residence Project 809367 January 2017 x 7-6: Wetlands in the Coastal Zone have been delineated following the definitions and boundary descriptions in Section 13577 of the California Code of Regulations. Pursuant to California Public Resources Code Section 30233, no impacts to wetlands will occur with project implementation. x 7-7: No impacts to wetlands will occur with project implementation. Therefore, no wetland mitigation would be required. x 7-8: The proposed project will not impact coastal sage scrub, maritime succulent scrub, southern maritime chaparral, southern mixed chaparral, native grassland, or oak woodland. x 7-9: No mitigation will be required for impacts to habitats stated in 7-8 since no impacts to these communities will occur. x 7-10: The property is not entirely or almost entirely constrained by ESHA. All impacts will occur within disturbed habitat. x 7-11: A 100-foot buffer will be implemented between wetlands and development. No riparian habitats or other native habitats occur on site that require a buffer beyond that required for wetlands. No fuel modification will take place within 50 feet of the wetlands on site. Buffer areas that do not contain native habitat shall be landscaped using native plants. Signage and physical barriers such as walls or fences will be required to minimize edge effects of development. x 7-12: In addition to the requirements of the model grading ordinance in the Carlsbad Master Drainage Plan, this project will comply with the following requirements: o Grading activity shall be prohibited during the rainy season: from October 1st to April 1st of each year. o All graded areas shall be landscaped prior to October 1st of each year with either temporary or permanent landscaping materials, to reduce erosion potential. Such landscaping shall be maintained and replanted if not well-established by December 1 st following the initial planting. o The October 1st grading season deadline may be extended with the approval of the City Engineer subject to implementation by October 1st of special erosion control measures designed to prohibit discharge of sediments off-site during and after the grading operation. Extensions beyond November 15th may be allowed in areas of very low risk of impact to sensitive coastal resources and may be DUDEK Biological Technical Report for the Martin Residence Project 809368 January 2017 approved either as part of the original coastal development permit or as an amendment to an existing coastal development permit. o If any of the responsible resource agencies prohibit grading operations during the summer grading period in order to protect endangered or rare species or sensitive environmental resources, then grading activities may be allowed during the winter by a coastal development permit or permit amendment, provided that appropriate best management practices (BMPs) are incorporated to limit potential adverse impacts from winter grading activities. x 7-12: In addition to the requirements of the model grading ordinance in the Carlsbad Master Drainage Plan, this project will comply with the following requirements: 6.4.3 Additional Mitigation Additional mitigation required is consistent with Sections 21.210.040C and E of the Zoning Ordinance. The project complies with the mitigation ratios contained in Table 11 in Section D.6 of the HMP by providing a fee for impacts to disturbed habitat as described in Section 6.1.1. 6.4.4 Coastal Zone Additional Information Refer to Section 6.4.2, Number 9 for an analysis of how the development complies with the additional conservation standards for Coastal Zone properties, contained in Section D.7-1 through D.7-14 of the HMP. 6.4.5 Other Additional Information None of the specific preserve related information is applicable to this project. Specifically, a proposed hardline preserve area does not occur on the project site. The existing hardline preserve is shown in relation to the proposed development area on Figure 4. The project is not located within a Standards Preserve Area. The project will not impact narrow endemic species. The project will not impact wetlands or the 100-foot buffer from the wetlands on site.
