The project site is located in the City of Carlsbad, within San Diego County. The proposed project site is within the City of Carlsbad's Multiple Habitat Conservation Program (MHCP) Subarea Plan boundaries. It is located outside of the Coastal Zone and is within the Standards Area or Local Facilities Management Zone Number 6. It is adjacent to a hardline preserve area. 1.1 Project Description and Location The proposed project is the construction of a single family residence. The project is located at the terminus of Managua Place in the City of Carlsbad, within San Diego County (Figure 1). The proposed project is south of Alicante Road north of San Marcos Creek, northeast of La Costa Resort golf course. The site is surrounded by existing single family residential development to the north, east, south, and City owned open space to the west. The site is located on the Rancho Santa Fe USGS 7.5' Quad in Township 12 South, Range 4 West (Figure 2). 1.2 Physical Characteristics Topography onsite is dominated by a level area near Managua Place which then quickly slopes off to the west. Topography onsite ranges from approximately 235 feet above mean sea level on the level area in the eastern portion of the site to approximately 180 feet above mean sea level near the southwestern property line. The project site has been disturbed in the past and partially leveled at some time. The western slopes of the site are currently undeveloped. Soils onsite consist of Exchequer rocky silt loam, 30-70% slopes (ExG) (Bowman 1973). 1.3 Onsite and Surrounding Land Uses The project site is currently undeveloped with native vegetation covering the western portion of the site. The eastern portion is disturbed and does not contain native vegetation. The project site is bounded by single family residences to the north and south, Managua Place to the east and undeveloped land to the west. 2.0 METHODS AND SURVEY LIMITATIONS On February 7, 2007 REC Consultants, Inc. (REC) biologist, Victor Novik, conducted a biological survey to confirm the habitats and wildlife use onsite. Field notes were maintained throughout the survey and all observed plant and animal species were documented. Habitats, sensitive plants, and sensitive animal locations were mapped on a 100-scale topographic map. April 2007 REC Consultants, Inc. 1 Managua Place Biological Technical Report I I I I I I I I I I I I I I I I I I I Nomenclature for animal species in this report follows American Ornithological Union (AOU 2000) for birds, Stebbins (2003) for reptiles and amphibians, SDNHM (1997) for mammals, and Powell (1979) for insects. Scientific nomenclature for plants follows the Jepson Manual: Higher Plants of California (Hickman 1996) as updated by Simpson & Rebman (2001 ). A limiting factor in survey methodology is the time of year during which the survey was conducted. The project site was not surveyed during spring and summer which may have resulted in many plants and animals not being observed. 3.0 EXISTING CONDITIONS The following discussion summarizes the existing biological resources on the proposed project site. This section includes discussion of habitats, wildlife, and sensitive resources onsite. 3.1 Habitats The project site currently supports two habitat types: black sage dominated coastal sage scrub and ruderal/disturbed (Figure 3). A complete list of plant species per habitat observed onsite is attached (Appendix A). Coastal Sage Scrub, 0.55 acre Coastal sage scrub habitat is comprised of low, soft-woody subshrubs. This habitat type is drought-deciduous, occurring typically on low-moisture availability sites such as dry slopes and hillsides or on clay-rich soils (Holland 1986). Coastal sage scrub is the dominant habitat on the western portion of the site. This habitat is primarily dominated by black sage (Salvia mellifera), bush mallow (Malacothamnus fasciculatus), California buckwheat (Eriogonum fasciculatum), California adolphia (Adolphia californica), laurel sumac (Malosma laurina), and lemonadeberry (Rhus integrifolia). Approximately 0.55 acre ofDiegan coastal sage scrub habitat occurs onsite. Ruderal, 0.63 acre Ruderal habitat typically includes areas that have some sort of disturbance associated with them in the past. Ruderal habitat is dominated by at least 50% cover of invasive broad-leaved non-native plant species including, but not limited to, horseweed (Conyza spp.), garland chrysanthemum (Chrysanthemum coronarium), pineapple-weed (Chamomilla suaveolens), sow-thistle (Sonchus spp.), Russian thistle (Salsola tragus), mustards, knotweed (Polygonum spp.), burclover (Medicago polymorpha), fennel and others. Minor amounts of other species including non-native annual grasses can also be present within this habitat. Areas labeled as ruderal habitat onsite are dominated by filaree (Erodium cicutaia), mustard (Brassica niger), and Russian thistle. Approximately 0.63 acre ofruderal habitat occur onsite. April 2007 REC Consultants, Inc. 2 Managua Place Biological Technical Report I I I I I I I I I I I I I I I I I I I 3.2 Wildlife Wildlife species were identified directly by sight or vocalization and indirectly by scat, tracks, or burrows. Four bird species and one amphibian were documented onsite. The majority of the bird activity onsite were house finches (Carpodacus mexicanus) and northern mockingbirds (Mimus polyglottos) observed flying through the site. A pacific tree frog (Hyla regilla) was heard calling on or near the site. A complete list of wildlife species observed onsite and the habitats in which they were observed is attached (Appendix B). No mammals were detected onsite. 4.0 SENSITIVE RESOURCES Sensitive or special interest plant and wildlife species and habitats are those, which are considered rare, threatened, or endangered within the state or region by local, state, or federal resource conservation agencies. Sensitive habitats, as identified by these same groups, are those, which generally support plant or wildlife species considered sensitive by these resource protection agencies. Sensitive species and habitats are so called because of their limited distribution, restricted habitat requirements, particular susceptibility to human disturbance, degradation due to development, invasion by non- native species, or a combination of all of these factors. Sources used for the determination of sensitive biological resources include: U.S. Fish and Wildlife Service (USFWS 2003); California Department of Fish and Game (CDFG 2003); California Native Plant Society (CNPS 2001), and City of Carlsbad HMP (City of Carlsbad 2001). There is one sensitive habitat: coastal sage scrub. There is one sensitive plant species California adolphia (Adolphia californica). No sensitive animal species were observed onsite. Each is discussed below. 4.1 Sensitive Habitats The City of Carlsbad HMP Subarea Plan protects sensitive habitats. Sensitive habitats are those which are considered rare in the region, support sensitive plants or animals, or receive regulatory protection. The one sensitive upland habitat onsite is coastal sage scrub. Coastal Sage Scrub This habitat, which is considered sensitive by the CDFG, USFWS, and City supports a number of state and federally endangered, threatened, and rare plants and animals which are currently listed or are being considered as possible candidates for listing. It is estimated that 70 to 90 percent of the original acreage of this habitat in the state has been lost as a result of urban expansion in coastal areas (Atwood 1990). Even in a disturbed condition, coastal sage scrub habitat may be considered sensitive by the resource agencies since it may still serve as habitat for wildlife and may be regenerating to higher quality coastal sage scrub habitat. Approximately 0.55 acre of sensitive upland habitat occur onsite. April 2007 REC Consultants, Inc. 3 Managua Place Biological Technical Report I I I I I I I I I I I I I I I I I I I 4.2 Sensitive Plants Sensitive plants include those listed by the USFWS (2002), CDFG (2001), and CNPS (2001). The CNPS listing is sanctioned by the California Department of Fish and Game and essentially serves as its list of "candidate" species for listing. The City of Carlsbad HMP stipulates that the City regulate populations of certain sensitive plants and animals within the boundaries of the HMP. This Plan allows the City to authorize the incidental take of covered state and federally listed species, as designated within the plan. The California adolphia (Adolphia californica) is considered sensitive. California adolphia (Adolphia californica) Listing: CNPS List: 2.1 Distribution: This species occurs in San Diego County as well as Baja California. Habitat: Typically found in chaparral, coastal scrub, valley and foothill grasslands. Conservation Status: Threatened by urbanization, road construction, non-native plants, and grazing. Status Onsite: This species is found throughout the coastal sage scrub onsite. Plant species have variable blooming seasons and may only be identifiable at a certain time of year. Since the site was visited early in the season, plants documented from the area have been assessed for their relative potential to occur within the habitats on the project site. Plant species with the potential to occur onsite are discussed in Appendix C. 4.3 Sensitive Wildlife Sensitive animal species include those species listed by USFWS (2003), CDFG (2003), and candidates for listing. The City Carlsbad Habitat Management Plan stipulates that the City regulate populations of certain sensitive animals within the boundaries circumscribed in the Plan. The Plan allows the City to authorize incidental take of covered state and federally listed species, as designated within the Plan, in accordance with the guidelines contained within the Plan. No sensitive wildlife were observed onsite or in the adjacent areas. The black sage dominated sage scrub provides a native habitat to be utilized by animal species. The adjacent canyon may provide a movement corridor for species. Sensitive animals with the potential to occur onsite are listed in Appendix D. 5.0 CITY OF CARLSBAD, STATE and FEDERAL REGULATORY REQUIREMENTS 5.1 Natural Communities Conservation Plan (NCCP) The City of Carlsbad Habitat Management Plan addresses issues pertaining to the conservation of natural biotic communities including sensitive plant and wildlife species, and to accommodate compatible land use. This Subarea Plan is the City's response to April 2007 REC Consultants, Inc. 4 Managua Place Biological Technical Report I I I I I I I I I I I I I I I I I I I USFWS and CDFG (Wildlife Agencies) requirements issued according to the state Endangered Species Act (ESA) and the NCCP of 1992. The Subarea Plan is the implementing agreement between the City of San Marcos and the Wildlife Agencies that remains consistent with Multiple Habitat Conservation Plan (MHCP) standards (City of Carlsbad 2004). 5.2 Adjacency Standards The City of Carlsbad has implemented a Habitat Management Plan (HMP) which will result in the conservation of native habitats and conservation areas adjacent to development of various types. In order to prevent negative effects of either area on the other, these adjacency standards must be addressed in the planning of any development habitat interface. These are discussed below along with the project's compliance. Fire Management Fire management must accomplish two objectives in the City of Carlsbad. These goals are the achievement of biological resources goals and hazard reduction for humans and property. "Fire management for human safety is one of the City's highest priorities." This will be accomplished in a manner that both ensures human safety and the conservation of biological resources. To meet the fire management needs, the project has implemented a three zone fuel modification plan in cooperation with the City of Carlsbad Fire District. The project will install sprinklers within the residence, to comply with the requirements of the first zone which is 20 feet in width and includes a portion of the house. The portion that extends outward from the house will consist of fire resistant landscaping. The second zone is 20 feet in width and will extend out from the first zone. This area will be non-irrigated and will be thinned so that 40% of the native vegetation remains onsite. The third zone will extend from the edge of the second zone 20 feet. This zone will be non-irrigated and will consist of native vegetation that is thinned to 60% cover. Although zones 2 and 3 will be thinned, they will still provide habitat for sensitive species. No fire related thinning will occur offsite. This area will be left in its natural state. Access for fire personnel to the canyon located adjacent to the site will be through either the SDGE easement located to the west of the site or through the site itself. Erosion Control "Erosion is promoted by the combination of erodable soils, steep slopes, soils with low water-holding capacities, sparse to no vegetation, and hydrologic conditions. Erosion can be aggravated by human disturbance and fire-control activities. Erosion hazards to biological resources include pollution and sedimentation of important water sources and the loss of vegetative cover from landslides. Management activities include:" • Identifying areas in need of erosion control, determining the cause of the erosion and ranking the effect of the erosion on the biological resources within the preserve. • Developing an erosion control plan. • Addressing slope stabilization and surface drainage. April 2007 REC Consultants, lnc. 5 Managua Place Biological Technical Report I I I I I I I I I I I I I I I I I I I The proposed project has addressed erosion control with the erosion control plan. This will include silt fencing at the bottom of all slopes during construction. This will ensure that runoff does carry silt offsite. Post construction water from the site will be collected and funneled to the south through drainage pipes. The outlet of the pipes contain rip rap which will help to reduce the effects of the water on the slope. In addition, all manufactured slopes near the conservation area will be planted with native plant species. This will aide in slope stabilization. If erosion is detected, onsite the property owner shall take remedial measures to correct the problems. Landscaping Restrictions At times landscaping is in conflict with biological objectives. This is often the case when non-native or invasive plant species are used in the plant palette, horticultural changes alter the site conditions, and genetic contamination occurs through the introduction of cultivated natives that may hybridize with native stock. To meet the objectives of the landscaping restrictions, all lands adjacent to the preserve will be left native but thinned for fire protection. Irrigation will not be used in these areas. Landscaping of manufactured slopes adjacent to the preserve will use native plant species, with temporary irrigation to establish the plants. Once plants are established, the irrigation will be shut off. Other landscaping on the site will consist of drought resistant Mediterranean types of plants that will not require the use of much water or fertilizer. Plants listed on Table 12 of the Carlsbad HMP as invasive will not be used onsite. Fencing, Signs, and Lighting "Fencing plays an important role in the use of the landscape by humans, domestic animals, and wildlife. Fencing can control human access, direct wildlife to road crossings, and prevent road kills. Fencing can also restrict the movement of wildlife." Signs can educate people as to the proper use of the preserve. Lighting has the potential to impact the nocturnal activities of native wildlife species. Fencing should not be used within the preserve where it may discourage the normal movement of animal species. However fencing may be appropriate at the edge of developments to discourage domestic animals and humans from entering the preserve. Onsite, the property will employ a vinyl coated fence to ensure that humans and domestic animals do not enter the preserve area. This fence will be partially buried to discourage the domestic animals from digging underneath the fence. It will be the property owner's responsibility to maintain the fence. Lighting should not be directed into the preserve. Lights will be kept near the residence and will be either low pressure sodium or will be shielded to avoid impacting the preserve. Predator and Exotic Species Control "Native species are often at a disadvantage after exotic species or non-native predators are introduced." Special management is recommended to control these pressures. These April 2007 REC Consultants, Inc. 6 Managua Place Biological Technical Report I I I I I I I I I I I I I I I I I I I include the fencing of the yard to restrict the access to the preserve by domestic animals which may prey upon native species and would discourage native species from habituating humans and food. Domestic animal food should not be left out for native species to feed upon. Trash should be kept in containers that are difficult for native animal species to access. If native animal species are observed utilizing the site in a way that is detrimental to the species, remedial steps should be taken to discourage the animal from continuing the activity. 6.0 PROJECT IMP ACTS Impacts on biological resources can be categorized as direct, indirect, or cumulative. Direct impacts are a result of project implementation, and generally include: the loss of vegetation and sensitive habitats and populations; the introduction of non-native species which may out-compete and displace native vegetation; activity-related to mortalities of wildlife; loss of foraging, nesting or burrowing habitat; destruction of breeding habitats; and fragmentation of wildlife corridors. Indirect impacts occur as a result of the increase in human encroachment in the natural environment and include: off-road vehicle use which impacts sensitive plant or animal species; harassment and or collection of wildlife species; intrusion and wildlife mortality by pets in open space areas following residential development; and inadvertent increased wildlife mortalities along roads. Cumulative impacts occur as a result of on-going direct and indirect impacts for unrelated or fragmented projects overall. Cumulative impacts are assessed on a regional basis and determined the overall effect of numerous activities on a sensitive resource over a larger area. Per CEQA, there are three levels of adverse impacts associated with biological resources: significant, locally important, and not significant. Each of these levels of impacts are defined below (Nelson 1981). Significant impacts would result if the project would affect regionally important or unique species or habitat that are susceptible to stresses or changes. These resources include federal or state-listed species, or their habitat; biotic communities, vegetation associations, and habitats of plant and animal species that are highly restricted on a regional basis; habitat that serves as a concentrated breeding, feeding, resting, or migrating ground and is limited in availability; biotic resources of scientific interest because they are at the extreme of either their physical or geographical limits or represent an unusual variation in a population or community; and areas that serve as habitats to regional plant wildlife and game populations and fisheries. Significant impacts may also occur if the activities of the proposed project would affect federal or state candidate species, regionally sensitive species, or species of special concern. The determination of significance is dependent upon the extent of impact with respect to the regional distribution of the resource. Locally important impacts may occur on resources that support the functioning and integrity of adjacent areas of high significance. These resources include habitats that are April 2007 REC Consultants, Inc. 7 Managua Place Biolog1cal Technical Report I I I I I I I I I I I I I I I I I I I key to the maintenance of localized plant and animal populations even if not significant on a regional basis; areas that act to buffer and protect resources of high significance; and corridors of zones that serve to link areas of high significance and facilitate their ecological interactions. Impacts which would not be considered significant include activities which may affect natural resources but would not change or stress the biological resources in the region. These areas include commonly occurring habitats and areas where biological resources have been previously removed or significantly altered. However, it should be noted, that common habitats may take on increased importance where they function as buffer zones to sensitive habitats or as wildlife corridors. 6.1 Direct Impacts The construction of the single family residence will impact 0.55 acre of coastal sage and 0.63 acre of ruderal/disturbed habitat. 6.1.1 Sensitive Habitats Coastal Sage Scrub The proposed project will impact 0.55acre of coastal sage scrub habitat. The City of Carlsbad considers this a sensitive habitat. Coastal sage scrub supports a variety of federally endangered, threatened, and rare plant and animal species. Any impact to the coastal sage scrub, therefore, is considered significant and would require mitigation. 6.1.2 Sensitive Plants The proposed project would impact the California adolphia located onsite. This loss would be considered significant and will require mitigation. 6.2 Indirect Impacts Indirect impacts would result from the changes in land use adjacent to natural habitats and primarily result form adverse edge effects. Short term impacts would be related to construction activities. 6.2.1 Sensitive Habitats The project site is located adjacent to a City-owned open space. This area is dominated by native vegetation. The project has the potential to impact the offsite resources both during and after construction. To avoid these indirect impacts to the offsite resource, proper BMPs should be used during construction and landscaping should be limited to areas adjacent to the structure. Landscaping should avoid the use of invasive plant species which may escape and invade the offsite habitat. April 2007 REC Consultants, Inc. 8 Managua Place Biological Technical Report I I I I I I I I I I I I I I I I I I I 6.3 Cumulative Impacts The proposed project will result in the loss of 0.55 acre of black sage dominated scrub and 0.63 acre of ruderal/disturbed habitat. The area is bound by development on three sides. The loss of habitat would be significant. However, cumulative impacts would be offset by the preservation of habitat associated with this project and other projects in conformance with the HMP and MHCP, thus reducing cumulative impacts to below a level of significance. 7.0 PROPOSED MITIGATION Under CEQA, the City's HMP and MHCP, mitigation is required for all significant biological impacts. These include, in order of preference: 1) avoidance of impacts, 2) minimization of impacts to the maximum extent practicable, and 3) mitigation, only if avoidance is not feasible and the impacts have been minimized. Whenever possible, the significant impact should be avoided using design alternatives, such as increasing development density in disturbed habitats while reducing or eliminating density in areas that support sensitive biological resources. If it is not feasible to avoid the impact due to either jurisdictional policy or to economic or topographic constraints, then minimizing of impacts should be considered. Impacts on significant resources should be minimized to the greatest extent feasible. Minimizing includes decreasing lot size, narrowing roadways, increasing buffer zones, etc. If unavoidable impacts to significant resources would still occur, a mitigation plan that would meet the requirements of the City of Carlsbad HMP. All mitigation will be accomplished through the payment into the City of Carlsbad "In Lieu Fee". This will occur at a ratio of 1: 1 for the black sage dominated scrub. 7.1 Sensitive Habitats Coastal Sage Scrub Typical mitigation ratios for impacts to coastal sage scrub vary, depending on habitat quality and/or the presence of coastal California gnatcatcher and/or other sensitive species. Generally, each individual project must be assessed for impacts and mitigation requirements. The proposed project will impact 0.55 acres of black sage scrub onsite. This will require mitigation at a ratio of 1: 1 for a total of 0.55 acre. This mitigation will reduce the impact level to that of below significant. The project will preserve 0.19 acre of black sage dominated scrub onsite. 7.2 Sensitive Species Sensitive Plants The loss of California adolphia will be offset by the preservation of habitat within the City of Carlsbad in accordance with the HMP. Sensitive Wildlife No sensitive wildlife were observed onsite. April 2007 REC Consultants, Inc. 9 Managua Place Biological Technical Report I I I I I I I I I I I I I I I I I I I 7.3 Mitigation for Indirect Impacts Mitigation to prevent indirect impacts to sensitive species will be addressed through the installation of fencing to exclude humans and domestic animals from the preserve areas. Potential indirect impacts from invasive plant species will be minimized by using species with a low potential to expand into the native habitats offsite. 7.4 General Mitigation The following general mitigation measures shall be applied to the project to protect the resources during construction: 1. The limits of the sensitive habitat will be flagged or fenced by a qualified biologist prior to grading to prevent inadvertent impacts to the habitat. 2. The coastal sage scrub must be monitored by a qualified biologist during any grading nearby to insure no impacts occur. 3. Grading should take place outside of the coastal California gnatcatcher breeding season (March 1 -August 31 ), unless a survey is conducted to confirm there are no gnatcatchers on or near the site. 4. Selectively place and/or shield light to avoid light from directly entering into the habitat from the proposed development and/or construction. No trash, oil, parking, or other construction related activities are to be allowed outside the grading limits April 2007 REC Consultants, Inc. 10 Managua Place Biological Technical Report I I I I I I I I I I I I I I I I I I I REFERENCES AOU. 2000.
