The purpose of this report is to provide a summary of biological resources in the study area, to evaluate the significance of impacts of the proposed project upon these resources and to discuss mitigation measures that could reduce these impacts to a less-than-significant level. This report serves as the technical analysis of the project's biological resources impacts under the Cahfomia Environmental Quality Act (CEQA). Five vegetation communities and five land covers were identified within the 28.93-acre study area. Vegetation communities present are Diegan coastal sage scrub (coastal sage scrub), disturbed coastal sage scrub, eucalyptus woodland, native grassland, non-native grassland, and riparian scrub (southern willow scrub and disturbed southern willow scrub). Unvegetated stream channel and concrete-lined open channel are not considered vegetation communities but are considered jurisdictional waters. Non-natural land cover types present are developed lands, disturbed lands and ornamental. Within the study area, approximately 8.99 acres are within the Coastal Zone, including areas mapped as coastal sage scrub (including disturbed coastal sage scrub), native grassland, developed, disturbed lands, and ornamental. Project impacts to sensitive uplands include 1.31 acres of coastal sage scrub (including disturbed coastal sage scrub), 0.02 acre of native grassland and 0.11 acre of non-native grassland. Impacts to jurisdictional areas include 0.40 acre of riparian scrub (southern willow scrub, disturbed southern willow scrub), 0.10 acre of unvegetated stream channel and 0.02 acre of concrete-lined channel. Proposed impacts to sensitive habitats within the Coastal Zone are limited to 0.35 acre of coastal sage scrub and 0.02 acre of native grassland. Impacts to sensitive uplands and jurisdictional areas are significant and would require mitigation. Impacts to a total of 16.54 acres of developed, disturbed lands, eucalyptus woodland and ornamental are not significant and mitigation is not necessary. Impacts to 0.96 acre of coastal sage scrub and 0.11 acre of non-native grassland outside of the Coastal Zone will be mitigated at 1:1 and 0.5:1 ratios, respectively, through offsite habitat preservation in a City of Carlsbad habitat mitigation bank. Impacts to 0.35 acre of coastal sage scrub and 0.02 acre of native grassland within the Coastal Zone will be mitigated at 2:1 and 3:1 ratios, respectively, including habitat creation within the Coastal Zone at a 1:1 ratio. The remaining component of mitigation for impacts to coastal sage scrub and native grasslands within the Coastal Zone will be provided through habitat preservation in a City of Carlsbad habitat mitigation bank. 4926-01 DUDEK V September 2007 Biological Resources Technical Report El Camino Real Road Widening Project Impacts to 0.40 acre of riparian scrub, 0.10 acre of unvegetated stream channel and 0.02 acre of concrete-lined channel will be mitigated at 3:1, 1:1 and 1:1 ratios, respectively, including habitat creation at a minimum 1:1 ratio. The remaining component of mitigation for impacts to riparian scrub will be provided through habitat preservation in a City of Carlsbad habitat mitigation bank. Impacts to Cooper's hawk, other raptors, and other migratory bird species nests protected under the Migratory Bird Treaty Act (MBTA) may be avoided by a) conducting vegetation clearing outside of the January - September bird breeding season or b) having a qualified biologist conduct a focused survey for bird nests not more than 72 hours prior to commencement of vegetation clearing activities. If active nests are found, impacts (both direct and indirect) may be avoided by ceasing construction within an appropriate buffer zone around the nest site until juveniles have fledged and the nesting cycle is complete. A minimum of a 50-foot buffer and up to a maximum of 300 feet for raptors will be determined by the project biologist. Impacts to nesting Cooper's hawk, Dulzura California pocket mouse, and northwestern San Diego pocket mouse, if present, will be mitigated through creation and/or preservation of riparian scrub and eucalyptus woodland (Cooper's hawk), and coastal sage scrub and grassland (pocket mice). Note tiiat the loss of approximately 0.73 acre of potential Cooper's hawk nesting habitat (0.33 acre eucalyptus woodland and 0.40 acre riparian scrub) would be mitigated through creation or preservation of 1.20 acres of riparian habitat and preservation of 0.03 acre of eucalyptus woodland. In addition, impacts to 0.33 acre of eucalyptus woodland and 2.60 acres of disturbed lands will be mitigated at a ratio of 0.1:1 at the Lake Calavera Mitigation Bank. Also, no sensitive, including federally- or state-listed, plant or animal species, were observed or are expected to occur on site. Therefore, no impacts to sensitive plant or animal species will occur and no mitigation is required. 4926-01 DUDEK vi September 2007 Biological Resources Technical Report El Camino Real Road Widening Project 1.0 INTRODUCTION Existing and potential biological resources on the approximately 28.93-acre study area for the proposed El Camino Real Road Widening Project were examined through field reconnaissance and evaluation of the potential of habitat to support sensitive wildlife and plant species. The purpose of this report is to provide a summary of biological resources in the study area, to evaluate the significance of impacts of the proposed project upon these resources and to discuss mitigation measures that could reduce these impacts to a less-than-significant level. This report serves as the technical analysis of the project's biological resources impacts under the California Environmental Quality Act (CEQA). 1.1 Project Description The City of Carlsbad (City) proposes to improve the section of El Camino Real fi-om Tamarack Avenue north to Chestnut Avenue. El Camino Real is a major north/south roadway serving as a vital parallel circulation element to Interstate 5 (1-5) for the Cities of Encinitas, Carlsbad and Oceanside. As various developments including subdivisions have occurred in the project vicinity, developers have been required to widen El Camino Real to fiiU prime arterial standards. This section of roadway, fi:om Tamarack Avenue to Chesmut Avenue, is one of the few remaining sections of El Camino Real that has not been widened to its fiall width of six travel lanes with three northbound and three southbound lanes. The proposed roadway improvements would result in a total width of 126 feet including 8-foot bike lanes on both sides of the street, three southbound lanes of 12-foot widtii each, an 18-foot wide landscaped median island, and three northbound lanes of 12-foot width each at the southern and northern ends of the project. In the middle section of tiie roadway, the roadway would transition between the previously discussed typical section to a modified width of 116 feet including a 6 Vi -foot bike lane on the west side of the roadway, three southbound lanes of 12 feet width each, a 14-foot-wide landscaped median island, three northbound lanes of 11 Vi feet width each, and a five-foot bike lane on the east side of the roadway. Parkways consisting of 5 Vi feet of sidewalk and 4 V2 feet of native vegetation (including a bioswale) would be provided on each side of the roadway resulting in a right-of-way width of 116 feet in this reach of the roadway. The project proposes to keep the existing vertical profile of the road. Additional characteristics of the proposed project are described below. Storm Drain: Currently, the roadway in the project area exhibits erosion on the embankment on the east side, pavement cracking and weathering, and bumps/sags. Storm water from the storm drains currently outlets at erosive velocities into a stream channel east of the roadway. Storm drains within the project footprint would be replaced and/or improved. The project includes the placement of erosion protection in the stream channel and/or construction of check dams within 4926-01 QII Q E1^ 1 September 2007 Biological Resources Technical Report El Camino Real Road Widening Project m m the ditch to remedy the issue. The pavement for the roadway would be overlaid with asphalt concrete and/or replaced with a full structural section as necessary. Brow ditches are proposed along the west side of El Camino Real to prevent hillside stormwater fi-om flowing over the sidewalk and onto El Camino Real. The proposed locations are at Stations 513+50 and 536+00. The sizes of the brow ditches would vary from approximately 12-inch minimum depth to 24-inch maximum depth. Lighting: Overhead lighting is proposed as part of the project. Lighting would be installed per applicable City standards for wattage and spacing. Each lighting pole would produce up to 22,000 lumens and would be staggered at 300-foot intervals along both sides of the project section of El Camino Real. Bus Stop: The existing North County Transit District bus stop located on the west side of El Camino Real just south of Chestaut Avenue would be relocated as part of the project, although the specific location is in the process of being determined in concert with North County Transit District. It is assumed that the chosen location would not be located outside of the project Area of Potential Effects (APE). Utilities: Depending on the availability of fimding, the existing overhead power lines along the west and east sides of El Camino Real may be imdergrounded as part of the project. Should fimding be available at the time of construction, possibly as a joint cost sharing effort with SDG&E, the City would underground these electrical utilities. If a fimding source for undergrounding is not located, the existing power poles along the west side, north of APN 207- 090-20, Station 526+00, are proposed to be relocated 5 to 10 feet to the west. The relocation or undergrounding of these poles is necessary to accommodate the proposed street widening. Retaining Walls: Retaining walls are proposed on the west side of El Camino Real in the approximate midpoint of the project area. The height of the retaming walls would vary between six to 15 feet high maximum. The specific wall types would be Caltrans cast-in-place concrete or masonry block cantilever with fascia for walls less than 10 feet in height. These have a concrete spread footing and a vertical retaining face. For walls over 10 feet in height, a tieback wall type would be implemented. This type of retaining wall is an anchored wall system that relies on steel bars grouted into the retained slope and a reinforced facing. The anchors are prestressed to provide an active clamping force. The facing is typically constructed with reinforced shotcrete or cast-in-place concrete, and are constructed with a "top-down" approach that does not require substantial excavation behind the wall face. 4926-01 DUDEK 2 September 2007 it Biological Resources Technical Report El Camino Real Road Widening Project The retaining walls are proposed to be built with a boulderscape architectural treatment and landscaping screening. Drainage systems would be included behind the walls to allow proper drainage of the adjacent hillside. Landscape Concept Plan: A Landscape Concept Plan has been prepared as part of the project to provide a transition between the ornamental landscape and natural landscape on either sides of the project reach of El Camino Real. The Landscape Concept Plan takes into account El Camino Real's scenic corridor designation by incorporating a median landscape treatment that continues adjacent median designs. The specific objectives of the design include low water use, minimization of fire hazards, minimization of visual impacts of the proposed retaining walls, and stabilization of disturbed slopes. Staging Areas: Staging areas for temporarily storing construction equipment would be identified during final design of the project, and would be located in previously paved areas within the APE. 2.0 METHODS 2.1 Literature Review Prior to the field investigation, a review of the existing biological resources within the vicinity of the project site was conducted using California Department of Fish and Game (CDFG) (2005 a- e) and the Inventory of Rare and Endangered Vascular Plants (California Native Plant Society [CNPS] 2005). General information regarding wildUfe species present in tiie region was obtained from Unitt (1984, 2004) for birds, Bond (1977) for mammals, Stebbins (2003) for reptiles and amphibians, and Emmel and Emmel (1973) for butterflies. 2.2 Field Reconnaissance Dudek biologists Phil Behrends, Ph.D (PRB), David FUetaer (DWF) and Kamarul Muri (KJM) conducted general and focused biological surveys of the study area between January and December, 2006. The surveys consisted of mapping vegetation communities, inventories of plant and wildlife species observed, a jurisdictional wetiands delineation, focused surveys for the state- and federally-listed endangered least Bell's vireo {Vireo bellii pusillus) and the federally- listed threatened coastal California gnatcatcher {Polioptila californica californica\ focused surveys for sensitive plant species, a habitat assessment for the federally-listed endangered Pacific pocket mouse {Perognathus longimembris pacificus), and a winter Monarch butterfly survey. Table 1 lists the dates, conditions, and focus of these surveys. 4926-01 DUDEK 3 September 2007 Biological Resources Technical Report El Camino Real Road Widening Project TABLE 1 Schedule of Surveys DATE HOURS STAFF FOCUS CONDmONS 1/3/06 1100- 1630 DWF, KJM Wetlands delineation, vegetation mapping, plant inventory 0 - 30% cloud cover, 0 - 4 mph wind, 65 - 72° F 1/12/06 1100- 1500 DWF, KJM Wetlands delineation, vegetation mapping, plant inventory. 30% cloud cover, 2 - 5 mph wind, 68 - 70" F 1/13/06 1045-1200 DWF Wetlands delineation (west side) 0 - 70% cloud cover, 2 - 5 mph wind, 58 - 60° F 1/31/06 0830- 1100 KJM Wildlife survey and habitat assessment 0 - 20% cloud cover, 1 - 3 mph wind, 58 - 63° F 3/22/06 1145- 1330 DWF Additional mapping, plant inventory 10% cloud cover, 3-8 mph wind, 65° F 3/30/06 0830- 1000 KJM Gnatcatcher survey 30 -100% cloud cover, 0 - 5 mph wind, 63 - 65° F 4/06/06 1000- 1135 KJM Gnatcatcher survey 50 -100% cloud cover, 0 - 5 mph wind, 60 - 65° F 4/13/06 0700 - 0830 KJM Gnatcatcher survey 0% cloud cover, 0-3 mph wind, 45 - 61" F 4/13/06 0615-0700 KJM Vireo survey 0% cloud cover, 0-3 mph wind, 45 - 61° F 4/21/06 0645 - 0850 KJM Vireo survey 60 - 100% cloud cover, 0 - 2mph wind, 60 - 64° F 5/2/06 0630-0800 KJM Vireo survey 100% cloud cover, 0 -1 mph wind, 62 - 64° F 5/11/06 0900- 1030 KJM Vireo survey 100% cloud cover, 0 -1 mph wind, 65 - 66° F 5/15/06 0500-0600 PRB Pacific Pocket Mouse Assessment Overcast, 0-3 mph wind 5/25/06 0600-0720 KJM Vireo survey 0% cloud cover, 0 mph wind, 57 - 58° F 6/7/06 0745 - 0845 KJM Vireo survey 100% cloud cover (fog, drizzle), 0 mph wind, 67° F 6/20/06 0830-0930 KJM Vireo survey 100% cloud cover, 0 mph wind, 69° F 7/6/06 0630-0735 KJM Vireo survey 100% cloud cover, 0 -1 mph wind, 72° F 7/12/06 0915-1130 DWF Rare plant survey 0% cloud cover, 0 - 2 mph wind, 80 - 83° F 12/7/06 0900- 1000 KJM Winter monarch butterfly survey 0% cloud cover, 0 mph wind, 59-60° F 2.2.1 Resource Mapping Upland vegetation communities were mapped in the field directly onto a 200-scale (1" ^ 200') color infrared aerial photograph flown in 2000 or a 100-scale color aerial photograph flown in 2005, both overlaid onto a surveyed topography map. The limits of riparian vegetation and jurisdictional waters were mapped in the field using a Trimble Asset Surveyor v 5.26 Global Positioning System (GPS) receiver with sub-meter accuracy; where access was difficult or GPS data could not be obtained, jurisdictional waters were mapped directly onto the 200-scale aerial photograph overlaid onto a topographic base map. The data were downloaded or digitized into a Geographic Information Systems (GIS) coverage with surveyed topography and a February 2005 real color aerial photograph using ArcGIS software. The areas of vegetation communities and lengths and areas of jurisdictional waters were calculated using the GIS software. Upland plant community classifications used in this report follow the City of Carlsbad (2004) Habitat Management Plan, except as noted. Wetlands communities and jurisdictional areas are classified according to both the City of Carlsbad's classification and that of Holland (1986), with modifications to include jurisdictional definitions commonly used by wetlands regulatory agencies. DUDEK 4926-01 September 2007 Biological Resources Technical Report El Camino Real Road Widening Project 2.2.2 Flora Plant species encountered during the field surveys were recorded, if they were identifiable at the time of the survey. Latin and common names of plants follow The Jepson Manual (Hickman, 1993) or more recent published taxonomic revisions of genera. Where not listed in Hickman (1993), common names are taken from Simpson and Rebman (2002) and Roberts (1998). A cumulative list of plant species observed in the study area is presented in Appendix A. The focused survey for sensitive plant species was conducted on July 12, 2006, during the blooming period of San Diego ambrosia {Ambrosia pumila\ Del Mar Mesa sand aster (Corethrogyne filaginifolia var. linifolia), and decumbent goldenbush (Isocoma menziesii var. decumbens), all plants considered to have a moderate or high potential to occur on site. All suitable habitat was surveyed on foot. 2.2.3 Fauna Wildlife species detected during the field surveys by sight, calls, tracks, scat, or other signs were recorded. Binoculars were used to aid in the identification of observed wildlife. In addition to species actually detected, expected wildlife use of the site was determined by known habitat preferences of local species and knowledge of their relative distributions in the area. A list of wildlife species observed on the property is presented in Appendix B. Latin and common names of animals follow Stebbins (2003) for reptiles and amphibians, American Ornithologists' Union (2006) for birds, Jones et al. (1997) for mammals, and Emmel and Emmel (1973) for butterflies. Mr. Muri (TE-051250-1) conducted focused surveys for the least Bell's vireo and California gnatcatcher. Focused surveys for least Bell's vireo were conducted in accordance with current U.S. Fish and Wildlife Service (USFWS) (2001) guidelines. The focused survey for least Bell's vireo included eight surveys between April 10 and July 31, with a minimum 10-day interval between surveys. Focused surveys for California gnatcatcher were conducted in accordance with ciurent USFWS (1997) guidelines. Surveys consisted of walking a meandering transect through appropriate habitat on the site. While walking the transect, taped gnatcatcher vocalizations were played approximately every 40 to 50 feet. Binoculars (10 X 50) were used to aid in detecting and identifying gnatcatchers and other birds. Phil Behrends, Ph.D, (TE 031287-6) conducted a habitat assessment for Pacific pocket mouse on May 15,2006. 4926-01 DUDEK 5 September 2007 Biological Resources Technical Report El Camino Real Road Widening Project 2.2.4 Jurisdictional Wetlands Delineation Mr. Flietner and Mr. Muri conducted a routine jurisdictional delineation of waters of the United States, including wetlands, under the jurisdiction of the U.S. Army Corps of Engineers (ACOE) and the California Regional Water Quality Control Board (RWQCB), and waters of the State, including riparian areas and wetlands, under the jurisdiction of the California Department of Fish and Game (CDFG) and California Coastal Commission (CCC). The jurisdictional wetlands delineation was conducted in accordance with the Corps of Engineers Wetlands Delineation Manual (TR Y-87-1) (ACOE 1987); hydrology, vegetation, and soils were examined at potential wetland sites. Munsell Soil Color Charts were used to determine soil chroma and value. The wetlands indicator status of the plant species was determined by using the National List of Plant Species that Occur in Wetlands: California (Region 0) (Reed 1988). Non-wetland jurisdictional waters of the U.S. were determined by observation of the ordinary high water mark. Areas under jurisdiction of the RWQCB were determined by the presence of hydrology indicators; these areas are generally coincident with waters of the U.S., but may also include isolated waters not under ACOE jurisdiction. Waters of the State under the jurisdiction of the CDFG were mapped based on the presence of one of three ACOE criteria (primarily vegetation) in association with a stream chaimel. Wetiand determinations were made at 19 sampling points (data stations) to determine whether jurisdictional waters, including wetlands were present. Areas of similar vegetation composition and topography were assumed to be under the same jurisdictions. The wetland determination forms for these data stations are included in Appendix C. To determine whether the waters on site were isolated, and thus not under ACOE jurisdiction, the stream channel was observed downstream and offsite. The limits of jurisdictional wetlands, as defined by the CCC, were determined by the presence of one of the three ACOE wetlands criteria, pursuant to the provisions of the California Coastal Act. The dimensions of wetlands and non-wetland jurisdictional areas (i.e., incised channels with no wetland vegetation) were recorded in the field with a GPS receiver with sub-meter accuracy. The data were downloaded into a GIS coverage using ArcGIS software and used to calculate stream lengths and areas. 2.2.5 Sensitive/Regulated Biological Resources Sensitive biological resources are those defined as follows: (1) species that have been given special recognition by federal, state, or local regulatory agencies due to limited, declining, or threatened 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 4926-01 Q y Q E1^ 6 September 2007 Biological Resources Technical Report El Camino Real Road Widening Project relatively limited distribution, or are of particular value to wildlife; (4) jurisdictional waters, including wetiands; and (5) wildlife corridors and habitat linkages. Regulated biological resources may or may not be considered sensitive, but are regulated under local, state, and/or federal laws. Sources used for determination of sensitive biological resources are as follows: wildlife, Carlsbad (2004), CDFG (2005b and d), and USFWS (2005); plants, Carlsbad (2004), CDFG (2005c and e), and CNPS (2001); habitats, Carlsbad (2004) and Holland (1986); jurisdictional waters, ACOE (1987) and methods described above; and wildlife corridors, Carlsbad (2004). An explanation of resource sensitivity categories is provided as Appendix D. 2.3 Survey Limitations Plant surveys were conducted in winter and early summer; most plant species would have been detected, with the potential exception of early-blooming spring annuals. The surveys were conducted during a year with below-average rainfall, and some plant species may not have germinated or grown large enough to be recognizable. Wildlife surveys were conducted in winter, spring, and eariy simmier, and most diurnal resident and spring migratory species would have been detected. Surveys were conducted during the daytime to maximize visibility for the detection of plants and most animals. Birds represent the largest component of the vertebrate fauna, and because they are active in the daytime, diurnal surveys maximize the number of observations of this portion of the fauna. In contrast, daytime surveys usually result in few observations of mammals, many of which may be active at night. In addition, many species of reptiles and amphibians are nocturnal or cryptic in their habits and are difficult to observe using standard meandering transects. 3.0 PHYSICAL CHARACTERISTICS 3.1 Site Description 3.1.1 Project Location and Regional Setting The El Camino Real Road Widening Project is located in the northeastern part of the City of Carlsbad, California (Figure /). The 28.93-acre study area extends south fi-om Chestnut Avenue at an elevation of approximately 300 feet above mean sea level (AMSL), to Tamarack Avenue, at approximately 70 feet AMSL in the southeast. This portion of El Camino Real is situated m a small canyon between northwest-southeast trending hills. The site is located on die U.S. Geological Service (USGS) 7.5 minute San Luis Rey quadrangle map in projected sections 4, 5 and 9; Township 12 South, Range 3 West (Figure 2). An isolated, intermittent blue line stream 4926-01 DUDEK 7 September 2007 m m m Biological Resources Technical Report El Camino Real Road Widening Project was mapped in the study area, running parallel and east of El Camino Real and dissipating into the valley extending southward toward Agua Hedionda. The project's Area of Potential Effects (APE) is that part of the 28.93-acre study area witiiin which potential environmental impacts would occur including construction related and potential long term effects. The APE is approximately 18.50 acres for the El Camino Real Road Widening Project, and is displayed in Figures 4 through 4D later in this report. The APE lies within the Habitat Management Plan for Natural Communities in the City of Carlsbad (HMP) plan area. The southwestern portion of die APE is withm tiie Coastal Zone and subject to applicable provisions of the HMP, which includes conservation measures required by the CCC (see Figure 2). 3.1.2 On-Site and Surrounding Land Uses The APE includes El Camino Real, a heavily-trafficked four-lane roadway, adjacent undeveloped land, and portions of intersecting streets. Residential development surrounds the APE, except for agricultural lands that extend to the east from the southern end of die APE. 3.1.3 Soils Two soil types dominate the APE; Gaviota fine sandy loam, 30 to 50 percent slopes in die northern half of the area, and Salinas clay loam, 2 to 9 percent slopes in die southeast. The periphery of tiie APE (i.e., the tops of the slopes) contains, fi-om north to southeast, small inclusions of Marina loamy coarse sand, 2 to 9 percent slopes; Carlsbad gravelly loamy sand, 15 to 30 percent slopes; and Las Flores loamy fine sand, 15 to 30 percent slopes, eroded. These latter three soil types are considered to provide substrates for sensitive plant taxa associated with southern maritime chaparral. Gaviota fine sandy loam soils are shallow soils formed from weathered marine sandstone. The topsoil is about 16 inches deep over rock and brown to yellowish-brown in color. Gaviota loamy coarse sand, 2 to 9 percent slopes is moderately permeable and has medium to high runoff Gaviota soils are classified as Entisols (Lithic Haploxeralf) (Bowman 1973). Gaviota loamy coarse sand, 2 to 9 percent slopes is not listed as a hydric soil (National Resource Conservation Service [NRCS] 2005). ii 4926-01 DUDEK ^ September 2007 Orange County Project S La Jolla San Diego m El Camino Real Widening Project - Biological Resources Report Regional Map FIGURE SOURCE: USGS, 7.5 Minute Series, San Luis Rey Quadrangle.

The dark gray- brown topsoil is neutral to mildly alkaline, with increasing alkalinity at greater depth. In some areas, the surface layer is clay. Salinas clay loam, 2 to 9 percent slopes has slow to medium runoff, and is moderately well-drained. Salinas soils are classified as a MoUisol (Calcic Pachic HaploxeroU) (Bowman 1973). Salinas clay loam 2 to 9 percent slopes is not listed as a hydric soil, although Salinas clay loam 0 to 2 percent slopes and Salinas loam 2 to 9 percent slopes are so listed (NRCS 2005). Marina loamy coarse sand, 2 to 9 percent slopes form on old beach ridges from iron-rich windblown sands. These very deep soils are composed of loamy coarse sands through almost the entire profile and are rapidly permeable and excessively drained (Bowman 1973). Carlsbad gravelly loamy sand, 15 to 30 percent slopes is derived from soft iron-rich sandstone weathered in place. The brown to pale brown surface layer and heavy loamy sand subsoil overlay a moderately deep, weakly cemented iron-silica hardpan. Carlsbad soils are classified as Inceptisols (Haplic Durochrepts) (Bowman 1973). Carlsbad gravelly loamy sands are not Usted as hydric soils (NRCS 2005). Las Flores loamy fine sand, 15 to 30 percent slopes, eroded are formed by the weathering of silica-rich marine sandstone and consists of loamy fine sand topsoil, a sandy clay subsoil, and a loamy coarse sand layer above the decomposing sandstone (Bowman 1973). 4.0 RESULTS OF SURVEY 4.1 Botany - Vegetation Communities and Floral Diversity Five vegetation communities and five land covers were identified on site. Vegetation communities present are Diegan coastal sage scrub (coastal sage scrub), disturbed coastal sage scrub, eucalyptus woodland, native grassland, non-native grassland, and riparian scrub (southern willow scrub and disturbed southern willow scrub). Unvegetated stream channel and concrete- lined open channel are not considered vegetation communities but are considered jurisdictional waters. Non-natural land cover types present are developed lands, disturbed lands and omamental. Vegetation communities and land covers are described below, their acreages are presented in Table 2, and their locations are shown in Figures 3, 3A through 3D. 4926-01 DUDEK '''' September 2007 Biological Resources Technical Report El Camino Real Road Widening Project TABLE 2 Vegetation Communities and Land Covers VEGETATION COMMUNrTY/ LAM) COVER TYPE ACREAGE Native Uplands Coastal sage scrub 4.27 Native Uplands Coastal sage scrub-disturbed 0.86 Native Uplands Native grassland 0.45 Native Uplands Native grassland-disturbed 0.14 Jurisdictional Wetlands/Waters'2 Riparian scrub (Southern willow scrub) 0,07 Jurisdictional Wetlands/Waters'2 Riparian scrub (Southern willow scrub) CDFG only 0.61 Jurisdictional Wetlands/Waters'2 Riparian scrub (Southern willow scrub-disturbed) CDFG only 0.11 Jurisdictional Wetlands/Waters'2 Unvegetated stream channel 0.44 Jurisdictional Wetlands/Waters'2 Concrete-lined channel 0.03 Non-native Land Covers Non-native grassland 0.38 Non-native Land Covers Developed 13.19 Non-native Land Covers Disturbed lands 6.23 Non-native Land Covers Eucalyptus woodland 1.40 Non-native Land Covers Omamental 0.78 T0TAL3 28^ ^ Holland (1986) nomenclature applies to wetlands and riparian communities. ^ Acreage is given to the hundredths place because of the greater accuracy of mapping for jurisdictional ^ Total may not sum precisely due to rounding. areas. 4.1.1 Coastal Sage Scrub (including disturbed) Diegan coastal sage scrub (coastal sage scrub) is characterized by drought-deciduous shrubs and subshrubs that often occur on dry south-facing slopes or on clay-rich soils that are slow to release stored water. Their leaves function mostly in the winter and early spring, with many plants being drought-deciduous. Characteristic species include California sagebrush (Artemisia californica), California buckwheat (Eriogonum fasciculatum), sages (Salvia spp.) lemonadeberry (Rhus integrifolia) and laurel sumac (Malosma laurina). A diverse understory of annual and perennial grasses and herbs is typically present (City of Carlsbad 2004). Coastal sage scrub occurs primarily on east-facing slopes on the west side of El Camino Real and between El Camino Real and the stream channel on the east side. Lemonadeberry and black sage are typically the dominant species in these areas, with California enceiia (Encelia californica), California sagebrush, and laurel sumac important components on the slopes west of El Camino Real. Coyote bush (Baccharis pilularis) is also common in places on the eastern side of El Camino Real. Smaller areas of flat or west-facing coastal sage scrub are dominated by California sagebrush; these areas also contain non-native grasses and sweet fennel (Foeniculum vulgar e).

El Camino Real Widening Project - Biological Resources Report Biological Resources Map FIGURE 3D Biological Resources Technical Report El Camino Real Road Widening Project Disturbed coastal sage scrub is defined as areas containing at least 20 percent cover of native coastal sage scrub vegetation but over 50 percent non-native plant cover. Disturbed coastal sage scrub includes the native species listed above, particularly coyote bush and black sage, but contains abundant pampas grass (Cortaderia selloana), sweet fennel, black mustard (Brassica nigra) and other invasive non-native species. Although disturbed coastal sage scrub is mapped separately to provide an accurate representation of the project, for the purpose of analyzing significance of impacts, it is combined with undisturbed coastal sage scrub. 4.1.2 Native Grassland (including disturbed) Native grassland (i.e., valley needlegrass grassland) is dominated by purple needlegrass (Nassella pulchra), a tussock-forming perennial grass that reaches about two feet in height. It usually occurs on fine-textured soils that are moist or wet in winter, becoming very dry in summer. On moister sites it often occurs among oak woodlands. Native annuals and grasses and non-native grasses, such as bromes (Bromus spp.) and wild oats, occur between the bunchgrasses, often forming most of the vegetative cover (Holland 1986). Native grassland is typically mapped when purple needlegrass exceeds ten percent cover. The east-facing slopes on the west side of El Camino Real support three patches of native grassland. Purple needlegrass and wild oat (Avena barbata) are the dominant grasses with purple needlegrass providing up to an estimated 60 percent of the vegetation cover. The southemmost patch of grassland west of El Camino Real is mapped as disturbed native grassland, because the grasses have been cut at the time of the summer survey; the purple needlegrass cover is estimated at 25 percent in this habitat. 4.1.3 Riparian Scrub Riparian scrub includes both natural and semi-disturbed wetland communities found along rivers and seasonal drainages, including southern willow scrub, mule fat scrub, and baccharis/tamarisk scrub. Dominant species in riparian scrub include willows (Salix spp.), Fremont cottonwood (Populus fremontii) and mule fat (Baccharis salicifoUa). The density of understory vegetation depends on the tree canopy, but it may include poison oak (Toxicodendron diversilobum), desert grape (Vitis girdiana) and western ragweed (Ambrosiapsilostachya). Riparian scrub on site consists of southern willow scrub and disturbed southern willow scrub. Arroyo willow is the dominant species in southern willow scrub on site, with a few mule fat present and usually no native understory vegetation. Non-native species, particularly pampas grass and sweet fennel, may be present in the understory. Areas of riparian scrub with greater than 50 percent non-native cover are mapped as disturbed southern willow scrub. 4926-01 DUDEK 18 September 2007 Biological Resources Technical Report El Camino Real Road Widening Project 4.1.4 Unvegetated Stream Channel Unvegetated stream channel typically describes ephemeral or intermittent stream channels with limited vegetation or that lack vegetation entirely. Ephemeral stream channels flow only briefly following rain events, whereas intermittent stream channels may include groundwater as a source of flows in addition to surface flows from surrounding areas. Unvegetated stream channel is mapped for the stream channel that runs the length of the study area along the eastern side of El Camino Real, as well as for small tributary streams. The main channel has a sandy bottom, varies from three to ten feet wide, and is unvegetated. Most of the channel flows through areas mapped as upland; where riparian vegetation occurs along the channel it generally occurs above the ordinary high water mark. The main channel is considered an intermittent stream channel as the presence of riparian vegetation in association with the stream channel suggests that groundwater or sufficiently frequent surface flows occur. A small tributary draining off the slope to the east of the main channel is considered ephemeral. 4.1.5 Concrete-lined Channel Concrete-lined channels are brow ditches and other concrete-lined structures that supply water to the unvegetated stream channel or riparian vegetation in the study area. The brow ditches on the east side of El Camino Real convey water from upper slopes into the natural channel. On the west side of El Camino Real, a brow ditch conveys water north into a small stream that flows into southern willow scrub. The brow ditch, concrete headwall, and pipe beneath Tamarack Avenue are also mapped as concrete-lined channel. 4.1.6 Developed Developed areas have been graded or buih upon. El Camino Real, Tamarack Avenue, Chestnut Avenue, paved driveways and private roadways, and a cement berm adjacent to El Camino Real are mapped as developed. 4.1.7 Disturbed Lands Disturbed lands refer to land that is repeatedly, or has been permanently, altered by previous human activity and to areas dominated by invasive exotic vegetation. Native or naturalized vegetation is no longer present and the land lacks habitat value for sensitive wildlife. Disturbed land is mapped for areas that lack vegetation entirely as the result of repeated plowing, recent eucalyptus cutting, or use for parking; dense stands (90-100 percent cover) of non-native weedy species that typically result from past disturbance; and for the linear strips adjacent to either side of El Camino Real that support only sparse annual weeds, presumably as a resuU of repeated roadside weed control activities. Large areas of ruderal vegetation in the eastern part of the site 4926-01 DUDEK ^9 September 2007 Biological Resources Technical Report El Camino Real Road Widening Project are dominated by Italian thisfle (Carduus pycnocephalus) or black mustard, other non-native species in disturbed lands include pampas grass, ice plant (Carpobrotus edulis), artichoke thistle, and fennel. These species usually occur in monotypic stands on site. 4.1.8 Eucalyptus Woodland Eucalyptus woodland is a non-native vegetation type dominated by various species of planted eucalyptus (Eucalyptus spp.), usually with a poorly developed or absent understory. Raptors and other birds often nest and bats often roost in eucalyptus woodland (City of Carlsbad 2004). Eucalyptus woodland is composed predominantly of blue gum (E. globulus) trees with or without understory vegetation. Where it occurs near the stream channel to the east of El Camino Real, understory vegetation is typically lacking beneath the dense canopy. Beneath the more open canopy on the slopes along the eastern edge of the site, non-native grasses and, occasionally, fennel, jade (Crassula argentea) or non-native plants are in the understory. 4.1.9 Non-native Grassland Non-native grassland contains wild oats and bromes, and other non-native annual grasses, as well as annual native herbs, such as telegraph weed (Heterotheca grandiflora) and fascicled tarweed (Deinandra fasciculata), and non-native herbs, such as black mustard and tocalote (Centaurea melitensis). Non-native grasslands may support raptor foraging and sensitive plant species (City of Carlsbad 2004). Non-native grassland on site is dominated by African fountain grass (Pennisetum setaceum), with non-native plants such as black mustard, Italian thistle, tocalote, sweet fennel, and weedy native annuals herbs such as horseweed (Conyza canadensis) also common. A patch of saltgrass (Distichlis spicata), a rhizomatous native grass, is also included as part of this vegetation type. 4.1.10 Ornamental Omamental is a vegetation type not considered as a habitat type within the City of Carlsbad (2004) nor as a distinct vegetation community by Holland (1986). It is included in this report as a non-natural land cover to distinguish areas occupied by omamental trees, including pines (Pinus spp.) and Peruvian pepper (Schinus molle) and groundcovers, such as hottentot-fig. Omamental vegetation occurs primarily on the west side of the study area near off-site residences. Included in this mapping is a small patch of arroyo willow (Salix lasiolepis), with an understory of garden nasturtium (Tropaeolum majus), Indian-fig (Opuntia ficus-indica) and other non-native species. The willows are not associated with a stream channel and apparently are maintained by runoff fi-om irrigated yards of the uphill residences. 4926-01 DUDEK 20 September 2007 Biological Resources Technical Report El Camino Real Road Widening Project Blue gum trees, though also a type of planted omamental tree, are mapped as eucalyptus woodland as described above. 4.1.11 Floral Diversity A total of 85 species of vascular plants, 43 native (51 percent) and 42 non-native (49 percent), have been noted on site (Appendix A). The site likely supports a greater diversity of annual plant species than would be apparent during the spring and summer. The high proportion of the vegetation cover provided by non-native plants, however, reflects the high level of disturbance and edge effects in this long narrow parcel of undeveloped land within an urban setting. 4.2 Zoology - Wildlife Diversity Thirty-eight wildlife species were observed during the wildlife reconnaissance and focused bird surveys (Appendix B). The wildlife recorded during these surveys generally were common species typically encountered in human-altered environments. 4.2.1 Reptiles and Amphibians The westem fence lizard (Sceloporus occidentalis) was the only reptile species observed. Other common species that may occur include side-blotched lizard (Uta stansburiana), southern alligator lizard (Gerrhonotus multicarinatus), and gopher snake (Pituophis melanoleucus), among others. No amphibian species were observed during the survey. The stream and riparian areas may support species such as Pacific treefrog (Hyla regilla) and westem toad (Bufo boreas). 4.2.2 Birds Thirty-one bird species were observed during the survey, including common, human-adapted species such as Califomia towhee (Pipilo crissalis), mourning dove (Zenaida macroura), wrentit (Chamaea fasciata), westem scrub-jay (Aphelocoma californica), lesser goldfinch (Carduelis psaltria), Anna's hummingbird (Calypte anna), and house sparrow (Passer domesticuis). Two common raptor species, red-tailed hawk (Buteo jamaicensis) and red- shouldered hawk (B. lineatus), were recorded. Bird species observed in riparian habitats include Pacific-slope flycatcher (Empidonax difficilis), Nuttall's woodpecker (Picoides nuttallii), warbling vireo (Vireo gilvus), yellow-mmped warbler (Dendroica coronata), and Wilson's warbler (Wilsoniapusilla). 4926-01 DUDEK 21 September 2007 Biological Resources Technical Report El Camino Real Road Widening Project 4.2.3 Mammals Five common mammal species were noted on the site: Virginia opossum (Didelphis virginica), brush rabbit (Sylvilagus bachmani), Califomia ground squirrel (Spermophilus beecheyi), woodrat (Neotoma sp.), and coyote (Cams latrans). Other common mammals that may occur include raccoon (Procyon lotor), Botta's pocket gopher (Thomomys bottae), and striped skunk (Mephitis mephitis), as well as a variety of small mice species. 4.2.4 Invertebrates One invertebrate species was recorded: checkered white butterfly (Pontia protodice). Other common butterflies are expected to occur, such as moming cloak (Nymphalis antiopa), acmon blue (Plebejus acmon), and west coast lady (Vanessa annabella). 4.3 Sensitive Biological Resources 4.3.1 Sensitive Plant Species Table 3 includes a list of sensitive plant species known to occur in Carlsbad or in the surrounding area and their potential to occur on site. Because of the general level of disturbance of the study area, the urbanized setting, and the lack of southem maritime chaparral vegetation, few sensitive plant species have potential to occur on site. Directed surveys were conducted for three sensitive plant species considered to have a moderate potential to occur: HMP narrow endemic (NE) Del Mar Mesa sand aster (Corethrogyne filaginifolia var. linifolia)', NE and federally listed endangered San Diego ambrosia (Ambrosia pumila); and CNPS List IB decumbent goldenbush (Isocoma menziesii var. decumbens). The surveys did not detect these species and no sensitive plant species are therefore considered to occur on site.

Sensitive habitats typically are vegetation communities that have undergone significant decline in the past and the wildlife and plants species associated with them have also been reduced in numbers. Onsite sensitive habitats are riparian scrub (southem willow scrub and disturbed southem willow scmb), coastal sage scrub (including disturbed), native grassland (including disturbed) and non-native grassland (including disturbed). As discussed below, riparian scmb provides potential nesting habitat for several sensitive migratory bird species, including the state- and federally-listed endangered least Bell's vireo. Coastal sage scmb provides potential habitat for the federally-listed threatened coastal Califomia gnatcatcher and other sensitive bird, mammal, and plant species. Native grassland and non-native grassland may support San Diego ambrosia. DUDEK 26 4926-01 September 2007 Biological Resources Technical Report El Camino Real Road Widening Project Disturbed lands and eucalyptus woodland are listed as HMP habitats in the City's HMP. Eucalyptus woodland may provide wintering and nesting or roosting habitat for some sensitive wildlife such as raptors, bats, and monarch butterfly, but the community dominated by this invasive exotic species is generally of lower habitat value than the native communities that it replaced. Disturbed lands may provide foraging habitat for raptors. 4.3.3 Sensitive Wildlife Species Table 4 provides a list of all known sensitive species that occur in the area and discusses their potential to occur on the project site. No sensitive wildlife species were detected during the initial wildlife reconnaissance survey of the study area. No state- or federally-listed threatened or endangered species were observed on site. Focused surveys for the coastal Califomia gnatcatcher and least Bell's vireo were negative. A habitat assessment for the Pacific pocket mouse determined that suitable habitat is not present. Existing coastal sage scmb is much too fragmented to support this species.

Cooper's hawk (Accipiter cooperii) and other raptors may nest in riparian habitat or eucalyptus trees on site, although existing traffic noise from El Camino Real may affect nesting. Dulzura Califomia pocket mouse (Chaetodipus californicus femoralis) and northwestern San Diego pocket mouse (C. fallax fallax) may be present in the open coastal sage scrub and/or grassland habitats on the site, but the long-time fragmentation of the habitat makes this area marginal for even these relatively common species. The abundant eucalyptus DUDEK 31 4926-01 September 2007 Biological Resources Technical Report El Camino Real Road Widening Project trees on site provide potential wintering habitat for monarch butterfly (Danaus plexippus). However, monarch butterfly were not detected during a winter roosting survey conducted within the eucalyptus trees on site. 4.4 Jurisdictional Waters Based on the 19 wetlands sample points (data stations) examined in the study area and subsequent mapping of riparian vegetation and jurisdictional waters, wetlands and waters under jurisdiction of ACOE, RWQCB, and CDFG are present in the study area. No jurisdictional waters are present within the portion of the study area within the Coastal Zone. The wetland delineation forms are provided in Appendix C. The locations of these jurisdictional waters are shown in Figure 3, 3A-3D and their areas are quantified in Table 5; areas under the sole jurisdiction of CDFG are denoted on Figure 3 by "-C".

The stream channel is therefore mapped as a water of the United States, with widths varying between 3 and 10 feet. The stream supports riparian vegetation sporadically throughout its length and is therefore considered to be an intermittent stream. Data station 10 is adjacent to a pair of small tributary streams feeding the central channel; although a single velvet ash (Fraxinus velutina) grows near the streams, these narrow, shallow channels are deemed to carry water only briefly following rainfall and are mapped as ephemeral channels occurring within uplands. Concrete-lined channels (i.e., brow ditches) in the study area are generally considered ephemeral waters of the U.S., being designed to convey water rapidly. A portion of concrete-lined channel at Tamarack Avenue is considered an intermittent waters of the U.S. because it occurs between riparian scrub. DUDEK 32 4926-01 September 2007 Biological Resources Technical Report El Camino Real Road Widening Project All channels on site eventually convey water into Agua Hedionda, a navigable waters of the U.S., and are under jurisdiction of ACOE, CDFG, and RWQCB. 44.2 ACOE Wetlands A small patch (0.07 acre) of southem willow scrub south of Tamarack Avenue is the only area that meets all three ACOE criteria. It includes a widened stream channel with standing water at the time of the survey and the first terrace up to about four feet above the channel. Areas under ACOE jurisdiction (data stations 11 and 12) were distinguished from the surrounding CDFG- jurisdictional area by indicators of wetlands hydrology. The CDFG-jurisdictional area (data stations 13 and 14) has the same species composition (arroyo willow and pampas grass) and low- chroma hydric soils. The presence of hydric soil indicators without evidence of wetlands hydrology in this case is thought to indicate that this higher-elevation area had been regularly flooded in the past, before channelization of the stream under Tamarack Avenue. This area is under jurisdiction of ACOE, CDFG, and RWQCB. 4.4.3 CDFG-Jurisdictional Riparian Areas Data stations 4, 8, 16, and 17 occur in southem willow scrub vegetation and have a predominance of wetlands species (e.g., arroyo willow), but lack evidence of wetlands hydrology and hydric soils. These areas are therefore not under federal jurisdiction, but meet CDFG criteria for jurisdictional riparian habitat. Similar areas of southem willow scrub and disturbed southem willow scmb throughout the site are also under CDFG jurisdiction. A total of 0.79 acre of riparian vegetation is under CDFG jiuisdiction. All other sampling points (data stations 2, 3, 5, and 9) are in upland vegetation and lack predominance of wetlands vegetation and hydrology and thus are not considered jurisdictional waters. One such location (data stations 2 and 18) does have hydric soils at depth, but these are considered to be residual indicators of the historic floodplain prior to development of the area and are not considered CDFG-jurisdictional. 4.5 Wildlife Corridor and Habitat Linl^age Wildlife corridors are linear features that connect large patches of natural open space and provide avenues for wildlife movement. Wildlife corridors contribute to population viability by maintaining genetic diversity through gene flow, providing access to adjacent habitat for foraging and mating, and providing routes for recolonization following local disturbance due to fire and other catastrophes. The City of Carlsbad (2004) considers a wildlife corridor to be a linear tract of land that species must travel through to reach suitable habitat for reproduction and other life needs. 4926-01 DUDEK 33 September 2007 Biological Resources Technical Report El Camino Real Road Widening Project Habitat linkages are patches of native habitat that connect two larger patches of habitat, helping to reduce the adverse effects of habitat fragmentation. A linkage provides a potential route for gene flow and long-term dispersal and may also serve as primary habitat for small animals, such as reptiles and amphibians. Habitat linkages may be continuous or a series of habitat islands that function as stepping stones for dispersal. The City of Carlsbad (2004) specifically identifies habitat linkages as a part of the HMP, with Linkages consisting of conserved habitat that provides a connection between the Core areas (large blocks of conserved habitat) and other natural habitat areas. The study area is not identified as a Linkage in the HMP (City of Carlsbad 2004). Riparian scmb occurs in the study area from north to south and continues to the southeast into a large block of agricultural land that continues into a large block of natural habitat surrounding Aqua Hedionda. Small mammals, birds, and reptiles may move between the study area and more extensive habitat areas to the south and east. However, the study area is surrounded by residential development to the east, west, and north, and, therefore, does not provide a corridor through which wildlife would pass to any other block of habitat. 4.6 Regional Resource Planning Context 4.6.1 Carlsbad Habitat Management Plan Several conservation planning efforts are currently in progress in San Diego County with the long-term goal of establishing a regional habitat reserve system that will protect native habitat lands and their associated biota. The Multiple Habitat Conservation Program (MHCP) is the subregional habitat conservation program for northwestem San Diego County, including the City of Carlsbad. The City's plan to implement the goals of the MHCP is through implementation of the Carlsbad Habitat Management Plan for Natural Communities in the City of Carlsbad (HMP), approved in 2004. The HMP is a comprehensive, citywide conservation program designed to preserve sensitive biological resources within the City while allowing for development consistent with the City's General Plan and Growth Management Plan. Specific biological objectives of the HMP are to conserve the hall range of vegetation types remaining in the City, with a focus on protecting rare and sensitive habitats and species. Conservation is achieved through designated Cores and Linkages that include "hard-line" preserves, where no development is permitted, and "soft-line" areas where a portion of the area may be developed. In addition, certain areas, designated as "Standards Areas" must be designed, permitted, and developed according to special land use regulations adopted by the City. Preserve assembly methods are specifically identified by Local 4926-01 DUDEK 34 September 2007 Biological Resources Technical Report El Camino Real Road Widening Project Facilities Management (LFM) Zones within the City, each with specific conservation goals and development restrictions. The HMP provides incidental take permits for five "covered" plant species and 17 wildlife species, based on a conservation analysis of existing, proposed, and allowable development impacts and proposed conservation measures. Upon adoption of other Subarea Plans within the MHCP planning area, an additional six plant species and 13 wildlife species would be covered under the plan. Specific conservation measures for certain covered species, such as survey requirements and minimization and avoidance measures for certain bird species, and preservation of 80% of narrow endemic plant (referred to as "NE" in this report) species outside of designated preserves are required by the HMP. The study area is located within the Local Facilities Management (LFM) Zones 1 and 2, which are divided at El Camino Real. The study area is not within a Core Area or Linkage. LFM Zones 1 and 2 are almost entirely developed, with scattered patches of natural vegetation, mostly on the slopes adjoining Buena Vista and Agua Hedionda Lagoons. The HMP Conservation goal for LFM Zone 1 is to conserve habitat contiguous to these lagoons. The study area is not within a Zone 1 Standards area. The HMP Conservation goal for LFM Zone 2 is to enhance Core Area 2, adjacent to the City of Oceanside, to assure the City of Carlsbad's portion of a regional Califomia gnatcatcher corridor. The study area is not within a Zone 2 Standards area. In accordance with the Carlsbad HMP, mitigation for impacts to Califomia gnatcatcher-occupied coastal sage scmb would occur at a 2:1 ratio, a 1:1 ratio for unoccupied coastal sage scmb, and a 0.5:1 ratio for annual grassland. Mitigation for impacts to jurisdictional waters requires no net loss, but varies by type of replacement habitat. City projects that impact unoccupied coastal sage scmb, armual grassland, disturbed lands, and eucalyptus will mitigate at the Lake Calavera Mitigation Bank and may mitigate out-of-kind. 4.6.2 Coastal Zone The Coastal Zone extends eastward from the cul de sac at the end of Alder Avenue into the study area and southward along the eastern edge of the El Camino Real right-of-way, encompassing 8.99 acres of the study area. Table 6 provides the acreages of the project's vegetation communities and land covers within the Coastal Zone. 4926-01 DUDEK 35 September 2007 Biological Resources Technical Report El Camino Real Road Widening Project TABLE 6 Vegetation Communities/Land Covers Within the Coastal Zone VEGETATION COMMU NTTY/LAND COVER TYPE ACREAGE Native Uplands Coastal saqe scrub 0.26 Native Uplands Coastal saqe scrub-disturbed 0.091 Native Uplands Native grassland-disturbed 0.022 Non-native Land Covers Developed 8.24 Non-native Land Covers Disturbed lands 0.32 Non-native Land Covers Omamental 0.063 TOTAL* 8.99 ^ 4,013 square feet ^ 715 square feet 3 2,703 square feet ^ Total may not sum precisely due to rounding The CCC regulates Environmentally Sensitive Habitat Areas (ESHA), including coastal sage scrub and native grassland, to protect these from significant disruption of habitat values. The Carlsbad HMP incorporates additional conservation standards to be applied to properties in the Coastal Zone to meet CCC requirements. General conservation standards that apply to portions of Carlsbad within the Coastal Zone include: • No net loss of sensitive uplands or wetlands habitats. • Mitigation for impacts to coastal sage scrub at a 2:1 ratio • Mitigation for native grassland at a 3:1 ratio • Natural buffers of 100 feet to wetlands and 20 feet to native uplands. 5.0 ANTICIPATED PROJECT IIVIPACTS This section addresses direct, indirect, and cumulative impacts to biological resources that may result from implementation of the proposed project. Direct Impacts consist of the loss of habitat and the plant and wildlife species that it contains within the Area of Potential Effect (APE) provided in December 2006. For the purposes of this assessment, all biological resources within the APE are considered 100% lost. Direct impacts were quantified by overlaying digital maps showing the APE on the vegetation map. Indirect Impacts are more difficult to quantify but may be as significant as direct impacts. They primarily result from adverse "edge effects," either short-term indirect impacts related to construction or long-term, chronic indirect impacts associated with the location of development in proximity to biological resources within natural open space. Few long-term indirect biological 4926-01 DUDEK 36 September 2007 Biological Resources Technical Report El Camino Real Road Widening Project impacts are anticipated because the project will expand the existing roadway without introducing new land uses into the area. Short-term indirect impacts that could potentially result from project construction include dust, which could affect plant growth and insect activity; noise, which could disrupt wildlife communication, including bird breeding behavior; lighting, which could disrupt behavior of nocturnal reptiles, mammals, and raptors; sedimentation, siltation, and erosion, which could affect water quality of on-site streams; and pollutant run-off, including chemicals used during construction and machinery maintenance, which could contaminate soil and water. However, implementafion of standard best-management practices (BMPs) required as part of the project permitting process will minimize these effects. Cumulative Impacts refer to incremental individual environmental effects of the proposed project and other past, present, and reasonably foreseeable fiiture projects when combined together. These impacts taken individually may be minor, but collectively may be significant as they occur over a period of time. 5.1 Direct Impacts 5.1.1 Vegetation Communities Direct permanent impacts include all areas within the proposed APE, as shown in Figure 4, 4A- 4D.

The project would have no direct impacts to sensitive plant species. 5.1.4 Sensitive Wildlife Species Nesting Cooper's hawk, Dulzura Califomia pocket mouse and northwestem San Diego pocket mouse, if present, may be impacted by loss of habitat. The project has the potential to impact 0.73 acre of potential Cooper's hawk nesting habitat (southem willow scrub and eucalyptus woodland) and 1.44 acres of Dulzura pocket mouse and northwestem San Diego pocket mouse habitat (coastal sage scmb and grasslands). 5.1.5 Regional Resource Planning Context The project is part of the El Camino Real Widening - South Chestnut to South Alga, which is covered by proposed City-lands mitigation bank (Carlsbad 2004). (Note: subsequent to the submittal of the HMP, the street name was changed to Aviara Parkway to the west of El Camino Real, and Alga Road east of El Camino Real). The project is therefore consistent with the Carlsbad HMP. DUDEK 43 4926-01 September 2007 Biological Resources Technical Report El Camino Real Road Widening Project 5.1.6 Coastal Zone The project would impact 0.35 acre of coastal sage scmb and 0.02 acre (715 square feet) of disturbed native grassland within the Coastal Zone. No narrow endemic plant species or Califomia gnatcatchers within the Coastal Zone would be impacted. 5.2 Indirect Impacts No additional long-term indirect impacts to sensitive vegetation, jurisdictional waters, sensitive plant or wildlife species, or regional wildlife corridors are anticipated because the project will not introduce new land usage in the vicinity. No short-term indirect impacts to sensitive vegetation, jurisdictional waters, sensitive plant or wildlife species, or regional wildlife corridors are anticipated because implementation of standard BMPs will reduce potential constmction-related effects. No potential indirect impacts due to noise during constmction are anticipated because sensitive species, such as the state- and federally-listed endangered least Bell's vireo and the federally-listed threatened Califomia gnatcatcher, are not present adjacent to the study area. 5.3 Cumulative Impacts Implementation of the El Camino Real Road Widening Project would contribute to the cumulative loss of biological resources within the City of Carlsbad. The cumulative loss of these resources may be considered significant, but mitigation for project impacts within Carlsbad would reduce these cumulative impacts. Furthermore, the project is consistent with the Carlsbad General Plan and HMP, which address the cumulative loss of biological resources within the City. 6.0 ANALYSIS OF SIGNIFICANCE 6.1 Explanation of Findings of Significance Impacts to native habitats, sensitive plants, and sensitive wildlife species must be quantified and analyzed to determine whether such impacts are significant under the Califomia Environmental Quality Act (CEQA). For purposes of this report, the proposed project may have a significant effect on the environment if the project has the potential to impact directly, indirectly, or cumulatively the following: (1) sensitive habitats; (2) sensitive species; (3) raptor foraging, habitat, or wildlife movement; (4) the ability of the City to implement the HMP; and (5) conformance with applicable ordinances, policies, and habitat conservation plans. The evaluation of whether an impact to a biological resource is significant must consider both the resource itself and the role of the resource in a regional context. Substantial impacts are those that 4926-01 DUDEK September 2007 Biological Resources Technical Report El Camino Real Road Widening Project contribute to or result in permanent loss of an important resource, such as a population of a rare plant or animal. Impacts may be important locally because they result in an adverse alteration of existing site conditions, but considered not significant because they do not contribute substantially to the permanent loss of that resource regionally. The severity of an impact is the primary determinant of whether or not that impact can be mitigated to a level below significant. 6.2 Direct Impacts 6.2.1 Sensitive Vegetation Communities Direct permanent impacts to vegetation communities and land covers listed as HMP habitats in the City HMP would be considered significant. Direct impacts to 1.31 acre of coastal sage scmb (including disturbed), 0.02 acre of disturbed native grassland, 0.11 acre of non-native grassland, 0.40 acre of southem willow scmb (including disturbed), 0.33 acre eucalyptus woodlands, and 2.60 acres disturbed land, all vegetation communities and land covers listed as HMP habitats in the City HMP, are considered significant. 6.2.2 Jurisdictional Waters Direct permanent impacts to 0.19 acre of waters, including wetlands, under the jurisdiction of ACOE, CDFG, and RWQCB, and an additional 0.33 acre of riparian vegetation under the jurisdiction of CDFG only (for a total CDFG-jurisdictional area of 0.52 acre) are considered significant. 6.2.3 Sensitive Wildlife Species Direct impacts to Cooper's hawk and other raptors are prohibited under Section 3503.5 of the Califomia Fish and Game Code. Potential impacts to nesting Cooper's hawk, Dulzura Califomia pocket mouse and northwestem San Diego pocket mouse, if present, would be considered significant. 6.3 Indirect Impacts No significant indirect impacts during constmction are anticipated because all potentially significant indirect impacts would be avoided through implementation of standard project BMPs. Potential indirect impacts due to noise during constmction are not significant because sensitive state- and/or federally-listed species are not present adjacent to the study area. 4926-01 DUDEK September 2007 Biological Resources Technical Report El Camino Real Road Widening Project 6.4 Cumulative Impacts No significant cumulative impacts would result from the project because the project is consistent with the Carlsbad General Plan and HMP, which address the cumulative loss of vegetation and wildlife habitat within the City. Long-term indirect impacts are not additive to existing indirect impacts from use of El Camino Real, so long-term indirect impacts are considered not significant. 7.1.1 Sensitive Vegetation Mitigation for significant direct impacts to sensitive vegetation communities consists of creation or preservation of vegetation communities in accordance with the Carlsbad HMP in the amounts shown in Table 9 and discussed below.

The loss of 0.02 acre (715 SF) of disturbed native grassland within the Coastal Zone (CZ) will be mitigated at a ratio of 3:1, including 1:1 habitat creation. Because only 0.02 acre of native grassland creation is required, this will be incorporated (as container plantings) into the coastal sage scrub habitat creation discussed below. The loss of 0.35 acre of CZ coastal sage scrub will be mitigated at a 2:1 ratio including habitat creation at a 1:1 ratio. A total of 0.37 acre of coastal sage scrub habitat will be created within the CZ, including a sufficient quantity of container plants as native grasses equivalent to the creation of 0.02 acre of native grassland. The remaining 1:1 mitigation for impacts to CZ coastal sage scrub, together with 1; 1 mitigation for non-CZ coastal sage scrub impacts, will be achieved DUDEK 46 4926-01 September 2007 Biological Resources Teclinical Report El Camino Real Road Widening Project through preservation of 1.31 acres of coastal sage scrub habitat by use of mitigation credit in the City of Carlsbad's Lake Calavera Mitigation Bank. Loss of 0.11 acre of non-native grassland will be mitigated by preservation of 0.06 acre of non- native grassland (or superior habitat) by use of mitigation credit in the City of Carlsbad's Lake Calavera Mitigation Bank. Impacts to 0.33 acre of eucalyptus woodland and 2.60 acres of disturbed lands will be mitigated by 0.03 acre and 0.26 acre habitat preservation, respectively, at the Lake Calavera Mitigation Bank and may be out-of-kind. 7.1.2 Jurisdictional Waters Mitigation for impacts to jurisdictional waters and riparian habitats include 1:1 creation in accordance with the "no-net loss" wetlands policy. As shown in Table 9, impacts to 0.40 acre of southem willow scrub (i.e., riparian scrub), including disturbed, will be mitigated at a 3:1 ratio, consisting of creation of 0.40 acre (1:1) of southem willow scrub and use of 0.80 acre (2:1) of mitigation credit in the City of Carlsbad's Lake Calavera Mitigation Bank. Impacts to 0.12 acre of ephemeral and intermittent stream channels will be mitigated through creation of 0.12 acre of stream channel (or superior) habitat. A total of 0.52 acre of wetland habitat will therefore be created in partial mitigation for wetland impacts. A Clean Water Act (CWA) Section 404 Nationwide Permit will be required from the ACOE for project impacts to 0.19 acre of ACOE-jurisdictional waters. Projects causing a loss of less than 0.50 acre of non-tidal waters of the U.S. qualify for Nationwide Permit 14 (Linear Transportation Crossings). A CWA Section 401 permit from the RWQCB will be required for impacts to 0.19 acre of waters under their jurisdiction. A Califomia Fish and Game Code Section 1602 Streambed Alteration Agreement will be required from the CDFG for impacts to 0.52 acre of jurisdictional waters and riparian vegetation. 7.1.3 Sensitive Wildlife Impacts to Cooper's hawk, other raptors, and other migratory bird species nests protected under the Migratory Bird Treaty Act (MBTA) may be avoided by a) conducting vegetation clearing outside of the January - September bird breeding season or b) having a qualified biologist conduct a focused survey for bird nests not more than 72 hours prior to commencement of vegetation clearing activities. If active nests are found, impacts (both direct and indirect) may be avoided by ceasing construction within an appropriate buffer zone around the nest site until 4926-01 QIJQEI^ 47 September 2007 Biological Resources Technical Report El Camino Real Road Widening Project juveniles have fledged and the nesting cycle is complete. A minimum of a 50-foot buffer and up to a maximum of 300 feet for raptors will be determined by the project biologist. Impacts to Cooper's hawk, Dulzura Califomia pocket mouse, and northwestem San Diego pocket mouse will be mitigated through creation and/or preservation of riparian scrub and eucalyptus woodland (Cooper's hawk), and coastal sage scmb and grassland (pocket mice) habitats discussed above. Note that the loss of approximately 0.73 acre of potential Cooper's hawk nesting habitat (0.33 acre eucalyptus woodland and 0.40 acre riparian scmb) would be mitigated through creation and preservation of 1.20 acres of riparian habitat, and preservation of 0.03 acre of eucalyptus woodland. 8.0 ACKNOWLEDGMENTS This report was prepared by Dudek biologist David Flietner.

Taxa likely to become endangered in the foreseeable future. Taxa for which the USFWS currently has on file substantial information on biological vulnerability and threat(s) to support the appropriateness of proposing to list them as endangered or threatened species. Taxa that were formerly Category 2 Candidates for listing as threatened or endangered. This category is an "unofficial" designation for species that may warrant listing, but for which substantial information to support the listing is lacking. STATE OF CALIFORNIA Endangered Threatened Rare Candidate California or CDFG Species of Special Concern Taxa which are in serious danger of becoming extinct throughout all, or a significant portion, of their range due to one or more causes including loss of habitat, change in habitat, over exploitation, predation, competition, or disease (Section 2062 of the Fish and Game Code). Taxa which, although not presently threatened with extinction, are likely to become endangered species in the foreseeable future (Section 2067 of the Fish and Game Code). Taxa which, although not presently threatened with extinction, are present in such small numbers throughout their range that they may become endangered if the present environment worsens (Section 1901 of the Fish and Game Code). Taxa which the Fish and Game Commission has formally noticed as being under review by the Department in addition to the list of threatened and endangered species. Taxa that appear to be vulnerable to extinction because of declining populations, limited ranges, and/or continuing threats.
