PHOTOS OF THE 0.57-ACRE LOT LOCATED AT 830 ORCUTT ROAD, SAN LUIS OBISPO, CA ...................................................................................... 56 BIOLOIGCAL RESOURCES SURVEY OF 830 ORCUTT ROAD, SAN LUIS OBISPO, CA 5 EXECUTIVE SUMMARY The proposed project site is a 0.57-acre lot located along the north side of the Orcutt Road at 830 Orcutt Road, San Luis Obispo, CA. Currently there is single-story home set back from Orcutt Road and screened by various landscape trees and shrubs. Behind the home (northern portion of the lot) is a detached garage and parking areas for the current residents. Driveways off Orcutt Road provide access to the lot. The subject lot is situated in an area along the north side of Orcutt Road that is zoned Service Commercial (C-S); therefore, the home is now surrounded my various commercial buildings and areas. Orcutt Road forms the lot’s southern boundary. Along the subject lot’s eastern boundary, there is an ephemeral creek that flows in a north to south direction and continues through a culvert under Orcutt Road and downstream toward Sacramento Street and Broad Street. This project proposes to demolish and remove the existing single-family residence and garage so that a mixed-use development consisting of a collection of multi-family residential and commercial use buildings with parking can be constructed on the lot. In order to provide affordable housing units, the developer was given a density bonus and one incentive or concession. The concession is to allow a minimum of two foot setback for the ephemeral creek where the usual requirement is a 20 foot creek setback. The City of San Luis Obispo has requested that the owner provide a biological resources study of the 0.57- acre lot. Dr. V. L. Holland conducted the biological resource surveys of the site on July 13 and 14, 2020. The purpose of this study is to characterize the biological resources on the lot and to provide technical information that evaluates the proposed mixed use development in sufficient detail to assess the potential effects of the project on the biological resources, especially the presence or potential presence of rare and endangered species and/or sensitive habitats and the creek setback. The natural vegetation on the subject lot and ephemeral creek was replaced long ago by the construction of the home, garage, parking areas, driveway, and landscape plants. Common plants on the upland areas of the subject lot (away from the creek bank) include a variety of planted trees and shrubs, coast live oaks, and several weedy grasses and forbs. The ephemeral creek does not have native riparian woodland but instead it is lined by mostly planted trees like Eucalyptus and Peruvian pepper trees with an understory of various ornamentals and weedy herbs. Therefore, except for the removal of one coast live oak, no significant impacts to native plant species or plant communities are expected. No special status plant or wildlife species that occur on the Department of Fish and Game Natural Diversity Data Base CNDDB lists of Special Status Species or in the California Native Plant Society (CNPS) Inventory of Rare and Endangered Vascular Plants of California database for San Luis Obispo and the eight surrounding quadrangles were found on the subject lot. None of these special status species are expected to occur on the site. I did not find any bird nests in the trees near the project site; however, if the trees are removed during the nesting season (September 1 to February 1), a nesting survey should be conducted within two weeks of starting construction to make sure no nesting birds will be affected. The project will not impact any of the native biological resources as the trees and vegetation removed from the site are introduced, planted trees, shrubs, and herbs with the exception of one coast live oak. All of the buildings are setback from the top of the bank by at least two feet as required by the concession. The Eucalyptus trees to be removed are located along the creek bank and near the bottom of the bank in the northeastern corner of the lot (Figures 2-4; Photo 5). This area will be landscaped open space after tree removal. Consideration should be given to planting coast live oaks where the Eucalyptus trees are removed. A sediment and erosion control plan should be implemented that will protect the creek banks and channel from erosion and prevent sedimentation of the creek near and downstream from the site. Current Best Management Practices (BMP) should be utilized. Washing of concrete, paint, tools, or equipment shall occur only in areas where polluted water and materials can be contained and removed from the site. BIOLOIGCAL RESOURCES SURVEY OF 830 ORCUTT ROAD, SAN LUIS OBISPO, CA 6 INTRODUCTION AND PURPOSE The proposed project site is a 0.57-acre lot located along the north side of the Orcutt Road at 830 Orcutt Road, San Luis Obispo, CA (Figure 1). Currently there is single- story home set back from Orcutt Road and screened by various landscape trees and shrubs (Photos 1 and 2). Behind the home (northern portion of the lot) is a detached garage and parking areas for the current residents. Driveways off Orcutt Road provide access to the lot. The subject lot is situated in an area (north side of Orcutt Road) that is zoned Service Commercial (C-S). North of the subject lot, the Service Commercial zoning changes to manufacturing zoning. The home is likely a remnant from when the area was residential; however, the home is now surrounded my various commercial buildings along its western and northern boundaries. Orcutt Road forms the lot’s southern boundary. South of Orcutt Road clusters of townhouses have been constructed or are under construction in residential planned developments. Along the subject lot’s eastern boundary, there is an ephemeral creek that flows in a north to south direction and continues through a culvert under Orcutt Road (Photos 3 and 4). South of Orcutt Road the creek continues flowing through the residential planned developments and then along the eastern boundary of Sacramento Drive toward Broad Street (Figure 1). There are commercial buildings east of the ephemeral creek that extend along the western boundary of the creek north of Orcutt Road. These businesses front on Duncan Lane. This project proposes to demolish and remove the existing single-family residence, garage, driveways, and landscaping so that a mixed-use development consisting of a collection of multi-family residential and commercial use buildings can be constructed on the lot. The Orcutt Mixed Use project will be composed of three residential buildings, with a total of fifteen townhome apartments, and one commercial building. Parking will be provided mostly by associated private garages with some supplemental surface parking (Figures 2 and 4). In order to provide affordable housing units in the residential development, the developer was given a density bonus and one incentive or concession. The concession is to allow a minimum of two foot setback for the ephemeral creek where the usual requirement is a 20 foot creek setback combined with the 10 foot setback for the third story. The two foot setback is necessary for the inclusion of the requested low income dwelling units and increased density in the proposed project. The City of San Luis Obispo has requested that the owner provide a biological resources study of the 0.57-acre lot. Dr. V. L. Holland conducted the biological resource surveys of the site on July 13 and 14, 2020. The purpose of this study is to characterize the biological resources on the lot and to provide technical information that evaluates the proposed mixed use development in sufficient detail to assess the potential effects of the project on the biological resources, especially the presence or BIOLOIGCAL RESOURCES SURVEY OF 830 ORCUTT ROAD, SAN LUIS OBISPO, CA 7 potential presence of rare and endangered species and/or sensitive habitats. During my analysis of the site, I carefully searched the entire 0.57-acre lot for sensitive habitats and species of concern known to occur in the San Luis Obispo and eight surrounding quadrangles (Tables 5-8 in Appendices 2 and 3). I evaluated the impacts of the two foot setback on the creek habitat. Figure 1. Location of the subject lot, outlined in white, located at 830 Orcutt Road, San Luis Obispo, CA. The ephemeral creek is shown by the blue dashed line. BIOLOIGCAL RESOURCES SURVEY OF 830 ORCUTT ROAD, SAN LUIS OBISPO, CA 8 Figure 2.

BIOLOIGCAL RESOURCES SURVEY OF 830 ORCUTT ROAD, SAN LUIS OBISPO, CA 9 EXISTING CONDITIONS, LOCATION, AND PHYSICAL FEATURES Location and Physical Features The rectangular 0.57-acre lot fronts on the north side of Orcutt Road. The topography is flat with an elevation range from approximately 212 to 230 feet. An ephemeral creek flows along the eastern boundary of the lot in a north to south direction, continues through a culvert under Orcutt Road, and continues downstream toward Broad Street (Figure 1; Photos 3 and 4). Upstream the creek flows through a culvert that runs under a commercial development and then into the creek channel the runs along the subject lot. So the creek corridor is broken up as it passes through several culverts upstream. The creek is seasonal and may have some flowing water for short periods during the winter rains but appears to be dry much of the year. During my July 2020 site visits, there were no signs of flowing or standing water in the creek. The ephemeral creek does not support native riparian or wetland vegetation; instead it is lined by tall Eucalyptus trees, Peruvian pepper trees, and a few native coast live oaks and toyons along with several other ornamentals. The subject lot has been landscaped with several ornamental species have been planted in the yard some of which are near the creek such as redwoods, Peruvian pepper, an Aleppo pine, and a coast live oak. The only native trees and shrubs along the creek are a few coast live oaks and toyon (Photos 1 to 5). Climate The general climate is classified as Subtropical Humid Mesothermal Cool- Summer Mediterranean with frequent fog (Csbn) using the Köppen-Trewartha system (Trewartha and Horn 1983). Winter high temperatures average approximately 62°F (16.7°C) and average low temperatures are near 41°F (5°C). Winter lows below 32°F (0°C) may occur from mid-November through mid- February. Summer high temperatures average approximately 77°F (25°C), and average low temperatures are near 52°F (11°C). Summer highs above 90°F (32°C) are not uncommon. Precipitation falls as rain, primarily from October through April, and averages approximately 16 inches (400 mm) per year. Less than one inch of precipitation is typically recorded from 1 May to 30 September, but overnight and morning fog with near 100% humidity is relatively common unless drier, down sloping winds descend from the Salinas Valley over the Santa Lucia Range to overwhelm the onshore flow of marine air (Felton 1965). Soils According to soil mapping delineations in the San Luis Obispo County Soil Survey (Ernstrom 1977) and the 2020 USDA Web Soil Survey (websoilsurvey.nrcs.usda.gov), the soils on the subject lot are Cropley clay, 0-2% slopes. Cropley clay soils are typically deep alluvial soils that form in valley and flat areas below hillsides. They normally have an effective rooting depth of 60 inches or more, low permeability, and high water and nutrient holding capacity. Surface runoff is low, and erosion hazard BIOLOIGCAL RESOURCES SURVEY OF 830 ORCUTT ROAD, SAN LUIS OBISPO, CA 10 is low to moderate. These clayey soils, like most clay-rich soils, may crack in the summer when they dry, but these cracks close in the wet season due to the shrink/swell characteristics of clayey soils. The natural vegetation on these soils in undisturbed sites is usually grassland. FLORISTIC, VEGETATION, AND WILDLIFE INVENTORY Methods Dr. V. L. Holland conducted biological surveys of the subject site on July 13 and 14, 2020. The purpose of these surveys was to carefully examine the existing flora, vegetation, wildlife, and biological habitats on the site with special attention given to the presence or potential presence of special-status species and sensitive habitats that might be impacted by the proposed project. During the analysis of the site, the entire lot and the ephemeral creek were carefully searched to determine if any of the target special-status species and habitats known to occur in the San Luis Obispo and the eight surrounding 7.5 minute/24,000 feet scale quadrangles (Tables 5-8 in Appendices 2 and 3) are present. The impact of the proposed setback from the ephemeral creek was examined. The biological surveys were conducted during the day light hours between 8:00 a.m. and 4:00 p.m. The weather on the survey days was sunny and partially cloudy with mild temperatures and little wind. During these surveys, I was able to identify most of the herbaceous plants using reproductive and vegetative features as well as the dried remains from this year’s standing crop. This study site was also carefully searched for any evidence of sensitive wildlife species and habitats that are listed by the U. S. Fish and Wildlife Service, California Department of Fish and Wildlife, or are known to occur in the general vicinity of the site. Trees on the lot were examined for nests, roosting sites, etc. No protocol wildlife surveys were conducted because the area was considered outside the range of wildlife species with specific protocol survey requirements or was determined not to support suitable habitat for these species. Consistent with recommended biological survey methodology, I carefully examined the lot using overlapping transects that zigzagged through the area. The plant species found within this study area are listed on Tables 2 and Appendix 1. I also looked for wildlife or signs of wildlife. Photographs were also taken. These methods allowed me to conduct a thorough and careful search for evidence of both sensitive and non-sensitive plant species, wildlife species, and sensitive habitats that are listed by the U. S. Fish and Wildlife Service, California Department of Fish and Game, California Native Plant Society, or are known to occur in the general vicinity of the site. During my examinations of the site, I recorded species presence and relative abundance with the goal of recording all species present on the site, including any rare species. To accomplish this, I surveyed the subject site until no new plant BIOLOIGCAL RESOURCES SURVEY OF 830 ORCUTT ROAD, SAN LUIS OBISPO, CA 11 species were found. (I did not include all the ornamental landscape plants and fruit trees in this study). While only repeated surveys conducted during all seasons, and even over a few years, provide an inventory nearing one hundred percent completeness, I am confident that the results of my studies provide an accurate inventory of the species present on the site during my July 2020 surveys, including any potential rare species known to occur in the general vicinity of the site. The site is a residential lot so there is no native vegetation left on the lot with the possible exception of the coast live oaks, which are likely natural but may have also been planted. References used to verify plant identifications include relevant floras: The Jepson Manual: Vascular Plants of California (Baldwin, et al. 2012); Vascular Plants of San Luis Obispo County, California (Hoover 1970), and Vascular Plants of San Luis Obispo County, California, 2nd ed. (Keil & Hoover, unpublished). Nomenclature follows that of the Jepson Manual (Baldwin, et al, 2012), and on-line revisions that can be accessed on the following website (http://ucjeps.berkeley.edu/IJM.html). FLORA, VEGETATION, AND WILDLIFE ON SITE Flora I made a list of all the native and naturalized plant species encountered in the project site. I also listed a few ornamentals that are in the yard near the creek. A list of common plant species is provided on Tables 2 and 3. Appendix 1 lists all plants found on the site. I found a total of 48 plant species on and around the site; however, it should be noted that most ornamental landscape plants are not included in this survey unless they are along or near the creek. Of the 48 plant species there are 7 trees (1 native; 6 introduced and planted), 10 shrubs (2 native to the site), and 31 grasses and forbs, only one of which is native to the site. Of the 48 species on the site, 4 are native and 44 are introduced. The results of the floristic analysis are summarized below in Table 1. Table 1.

Plant associations are spatially and temporally dynamic. Definitions and boundaries are relative and respond to the sharpness of the controlling environmental factors. Plant BIOLOIGCAL RESOURCES SURVEY OF 830 ORCUTT ROAD, SAN LUIS OBISPO, CA 12 communities are not usually discrete but often transition into one another, forming ecotones or transition zones. Native vegetation found on residential lots almost always have several planted ornamentals and fruit trees as well as many weedy plants. This human modified vegetation cover, which covers the lot and ephemeral creek, is referred to an Urban Association. Urban Associations The natural and native vegetation on the subject lot was replaced long ago by the construction of the home, garage, parking areas, and driveway. In addition, the homeowners have landscaped the lot, including areas along the ephemeral creek, with a variety of ornamental landscape plants that have mixed with the remnants of native and naturalized vegetation. Weedy, introduced grasses and forbs are mixed with the landscape plants sometimes forming dense stands of weedy grasses and forbs. Common plants on the upland areas of the subject lot (away from the creek bank) include a variety of planted trees and shrubs and several weedy grasses and forbs. The weedy plants are scattered on the lot, but a dense stand occurs along the back of the lot along the lot’s northern boundary (Table 2) Table 2.

Downstream from the subject lot (south of Orcutt Road), portions of the creek is lined by native riparian woodland vegetation consisting mostly of arroyo willow trees. However, the small stretch of the creek that runs along the eastern boundary of the subject lot is lined by tall Eucalyptus trees, Peruvian pepper trees, coast live oaks, and an Aleppo pine. There are also a few small coast live oaks and toyons along the creek (Photos 3-5). The understory consists of the herbaceous plants and a few scattered shrubs including the native toyon and introduced big-leaved cotoneaster and cape plumbago. Weedy grasses and forbs make up the majority of the flora on the creek bank under the trees and along the edge of the creek channel. However, there are several scattered umbrella sedges, which is a native species, that occur in the along the creek channel. The creek channel itself is mostly rocky and gravely and barren of vegetation (Photos 3 and 4). The creek bank on the opposite side east of the subject lot has a thicket of periwinkle along with big-leaved cotoneaster, cape plumbago, Nasturtium, and scattered weedy plants. Ornamental trees and shrubs have also been planted on the adjoining lot next to the creek. As mentioned previously, two tall sycamore trees occur on the upper bank oppositie the subject lot near Orcutt Road. BIOLOIGCAL RESOURCES SURVEY OF 830 ORCUTT ROAD, SAN LUIS OBISPO, CA 14 Table 3.

Introduced or naturalized species are exotics introduced to California in historic times from other parts of the world and now reproducing spontaneously in California and on the study site. Ornamentals are used as landscape plants but sometimes can escape and grow along the creek WILDLIFE As described previously in this report, the subject site is a residential lot within an area with commercial buildings; therefore, the whole area has lost most of its native wildlife habitat value or its value has been highly disturbed. As a result, the wildlife habitat has been highly compromised and degraded. Commercial development and roads surround the subject lot. In addition, the area along the ephemeral creek is now covered mostly by mixture of planted introduced trees and shrubs with an understory of weedy and ornamentals plants. Consequently, the creek provides no or very little native riparian habitat for wildlife. The wildlife expected in the area would be species typical of urban residential and commercial developments. Some of these species are those listed in Table 4 below. No signs of special status wildlife species were found, and none would be expected to use this site. Table 4. List of some of the wildlife species known to occur in local residential and commercial areas near the subject lot. None of these species are considered rare or have special status.

The results of this search are found in Tables 5-7 in Appendix 2. Table 5 provides information on the current rarity status of these target special status species, and Table 6 provides information on life form, flowering period, and elevation range. I also investigated the habitat requirements for all the special status species found in our nine-quadrangle search and evaluated whether or not potential habitats for these species exist on the project site. Results of these investigations and determinations are shown on Table 7. To generate these lists, I referred to the most recent edition of the California Department of Fish and Game Natural Diversity Data Base: Special Vascular Plants, Bryophytes, and Lichen List (CNDDB) and the most recent edition of the California Native Plant Society (CNPS) Inventory of Rare and Endangered Vascular Plants of California database, both of which are accessible through the internet (http://www.dfg.ca.gov/whdab/html/cnddb.html and www.cnps.org). This search revealed 75 special status plant species that occur within the San Luis Obispo and eight surrounding quadrangles, 34 of these plant species have been reported to occur within the San Luis Obispo quadrangle (Table 5 Appendix 2). Those found in the San Luis Obispo quadrangle are in bold in Table 5. Most of the rare plants on the list are not expected to occur on the study site because they are highly restricted in distribution range, in habitat requirements, and have never been reported growing in the San Luis Obispo quadrangle or near the site. BIOLOIGCAL RESOURCES SURVEY OF 830 ORCUTT ROAD, SAN LUIS OBISPO, CA 17 I conducted careful biological surveys of the 0.57-acre lot and surrounding areas and no special status plants were found. The proposed mixed use project is proposed for a developed and highly disturbed residential lot. There is no evidence of any special status plant species on or near the subject lot. Please refer to Table 7 in Appendix 2 for information about the habitats in which special status species occur. The timing of these surveys falls within a period of time when some of the plants would not be in identifiable condition; however, I think most of the weedy grasses and forbs could be identified using reproductive and/or vegetative features as well as the dried remains of this season’s standing crop. Trees and shrubs can be identified using vegetative features. I carefully searched for any signs of special status species on the project site, but none was found. SPECIAL STATUS WILDLIFE SPECIES To determine the special status wildlife species that could potentially be present on the project site, I conducted a search for target special status species known to occur within the San Luis Obispo (246C), Pismo Beach (221B), Lopez Mountain (246D), Port San Luis (222A), Morro Bay South (247D), Morro Bay North (247A, Arroyo Grande NE (221A), Santa Margarita (246A), and Atascadero (246B). 7.5 minute/24,000 scale quadrangles. The special status wildlife species revealed in the nine-quadrangle search are listed in Table 8, Appendix 3. To generate this list, I referred to the most recent edition of the California Department of Fish and Game Natural Diversity Data Base (CNDDB) and other appropriate publications. A survey for special status wildlife species was conducted on the 0.57-acre lot and surrounding areas to determine actual and potential utilization of this site by wildlife species that have special listing. The project site is a developed, disturbed residential lot surrounded by commercial buildings. Only a few wildlife species would be expected to use the subject lot. During my surveys no signs (scat, tracks, fur, or live observations) of special status wildlife species were observed. For the most part, special status animal species that occur within the San Luis Obispo and surrounding quadrangles (Table 8; Appendix 3) are highly restricted both in distribution range and in habitat requirements and are not expected to occupy the urban habitats found on and around the subject lot. For example, some rare animal species occur in salt or brackish water, e.g., the Tidewater goby; some require permanent standing water, e.g., Steelhead; some occur in vernal pools, e.g., the fairy shrimp; some occur only in specific soils and or other substrate conditions, e.g., the globose dune beetle (fore dune sands) and Morro Bay shoulderband snail; some require specific roosting sites, e.g., the bat species; some require large, deep bodies of water, e.g., the western pond turtle and red-legged frogs; some require permanent standing water to lay their eggs; e.g. coast range newt. In addition, the site is simply out of the geographic range in which many special status species have been found, e.g., Atascadero June beetle. None of the specialized habitats listed above occur on or near the subject lot. BIOLOIGCAL RESOURCES SURVEY OF 830 ORCUTT ROAD, SAN LUIS OBISPO, CA 18 The ephemeral nature of creek precludes the potential of the property to maintain water throughout the year; therefore, there is no or extremely marginal habitat for any of the special status amphibians such as species of salamanders, Arroyo toads, California red-legged frogs, foothill yellow-legged frog, or western spadefoot. The same is true for the bird species that utilize water, or those restricted to wetland or oceanic communities. Birds that prefer or require grassland habitat would not be present as there is no suitable grassland habitats on this property. The lack of adequate open areas or grassland precludes utilization by many listed bird species including the tri-colored black bird, the grasshopper sparrow, Belding’s savannah sparrow, burrowing owls, loggerhead shrikes, and California horned larks. The raptor species noted in the CNDDB reports could potentially fly over the area, but there is no adequate open areas for them to hunt and forage on or near the subject lot. The trees on the property were examined for the presence of bird nests, and none was observed. No signs of any special status species of birds were found on the lot or adjacent areas. There is not adequate habitat for any of the listed reptiles, and no signs of legless lizards, two striped garter snake, or coast horned lizards were found on the site. Likewise, none of the mammals listed in the CNDDB reports were found or expected to use the subject lot, including the ephemeral creek. The marine mammals (Northern fur seal and Stellar’s sea lion) are obviously precluded. The opportunity for special status bats to utilize the property is remote at best. No roosting habitat exists for the special status bat species. No signs of woodrats were found on the site or upstream from the site. It must also be noted that the potential presence of domestic dogs and cats in the general neighborhood will deter woodrat occupancy. There is no suitable habitat for the special status mammal species, including the American badger and Morro Bay kangaroo rat. . There are a few large mature planted trees along the creek both on the subject site adjacent properties that occur next to the creek on the site. These trees could potentially provide nesting sites for birds; however, the special status bird species are very unlikely to nest in the trees near the property because of the human activities that occur each day in the residential lot and in the surrounding commercial areas. If the trees are removed during the nesting season (September 1 to February 1), a nesting survey should be conducted prior to their removal. No signs of special status wildlife species were found on the subject lot or surrounding areas; therefore, no impacts to special status wildlife is expected as a result of the proposed project. In conclusion, there is no habitat on the project site for any of the special status wildlife species listed in Table 8. Appendix 3 provides information about the habitats of these special status species and why it was concluded they are not present on the project site. BIOLOIGCAL RESOURCES SURVEY OF 830 ORCUTT ROAD, SAN LUIS OBISPO, CA 19 CONCLUSION AND POTENTIAL IMPACTS TO BIOLOGICAL RESOURCES AND RECOMMENDED MITIGATION MEASURES This project proposes to demolish and remove the existing single-family residence and garage so that a mixed-use development consisting of a collection of multi-family residential, commercial use buildings and parking can be constructed on the lot. The developer was given a density bonus and one incentive or concession. The concession is to allow a minimum of two foot setback for the ephemeral creek bank. The project will not impact any of the native biological resources as the trees and vegetation removed from the site are introduced, planted trees, shrubs, and herbs with the exception of one coast live oak as described below. Creek Setback: All of the buildings are setback from the top of the bank by at least two feet as required by the concession (Figures 3 and 4). The Eucalyptus trees to be removed are located along the creek bank and near the bottom of the bank in the northeastern corner of the lot (Figures 2-4; Photo 5). This area will be landscaped open space after tree removal. Consideration should be given to planting coast live oaks where the Eucalyptus trees are removed. Figure 3. Shows the approximate location of the top of the creek bank (blue dashed line) in relationship to the proposed building locations. The creek setback will be a minimum of two feet.

Shows where the Eucalyptus trees and top of the creek bank (blue dashed line) on the lot are located. Top of Bank BIOLOIGCAL RESOURCES SURVEY OF 830 ORCUTT ROAD, SAN LUIS OBISPO, CA 21 Native Plant Impacts: The plants on the residential lot is composed of mostly of ornamental landscape plants and introduced, weedy grasses and forbs on the both the upland portion of the lot as well as along ephemeral creek. No native riparian vegetation occurs along this section of the creek. The only native tree affected will be the removal of a coast live oaks (24 inch DBH). Other than that only planted, introduced trees will be removed (three Eucalyptus trees, eight Peruvian pepper trees, one pine tree, three palm trees, and four planted coastal redwood trees). Therefore, except for the removal on the on coast live oak, no significant impacts to native plant species or plant communities are expected. Special Status Species: No special status plant or wildlife species that occur on the Department of Fish and Game Natural Diversity Data Base CNDDB lists of Special Status Species or in the California Native Plant Society (CNPS) Inventory of Rare and Endangered Vascular Plants of California database for San Luis Obispo and eight surrounding quadrangles were found on the subject lot or ephmeral creek (Tables 5-8 in Appendices 2 and 3), and none are expected to occur on the site. In Tables 7 and 9 in Appendices 2 and 3, I discuss potential special status species of plants and wildlife in detail and explain why I would not expect them to occur on or use the project site. No impacts to special status plant or wildlife species will occur as a result of the proposed project. It is always important to carefully evaluate any area that has a source of water near a project site, as there are three special status wildlife species that could be of concern as a result of the presence of water. The three species that I carefully examined and evaluated are California red-legged frog, southwest pond turtle, and steelhead trout. I accessed the creek habitat as to whether potential appropriate aquatic habitats exist for them to survive and complete their life cycle on or near the project site. My conclusion is that there is no suitable habitat for these species on or near the subject lot. However, ephemeral creek may offer habitat elsewhere along its corridor for these species, such as the downstream areas south of the subject lot. Nesting birds: Typically, it is recommended that disturbances and/or construction activities should occur outside the typical nesting season (September 1 to February 1) if possible to avoid impacts to potential active bird nests. I did not find any bird nests in the trees near the project site during our surveys; however, because our surveys were outside the typical nesting season, further nesting studies of the site may be needed. If the trees are removed during the nesting season, a nesting survey should be conducted within two weeks of starting construction to make sure no nesting birds will be affected. If active nests are found, adequate buffer zones and/or mitigation measures will need to be established. Landscaping: I recommend that native riparian trees or coast live oaks be planted along the ephemeral creek where the three large Eucalyptus trees are removed if possible. No invasive plant species listed in the California Invasive Plant Council BIOLOIGCAL RESOURCES SURVEY OF 830 ORCUTT ROAD, SAN LUIS OBISPO, CA 22 are included in the landscaping of the site. Many ornamental plants have already invaded and become established along the creek as it traverses the commercial and residential areas. Erosion control: A sediment and erosion control plan should be implemented during construction as necessary to protect the creek banks and channel from erosion. Erosion control will prevent sedimentation of the creek channel near and downstream from the site. . Current Best Management Practices (BMP) should be utilized. All pollutants originating from construction equipment should be collected and disposed of as necessary. For example, washing of concrete, paint, tools, or equipment should occur only in areas where polluted water and materials can be contained and removed from the site.

California Rare Plant Rank 1A: Plants Presumed Extirpated in California and Either Rare or Extinct Elsewhere Plants with a California Rare Plant Rank of 1A are presumed extirpated or extinct because they have not been seen or collected in the wild in California for many years. A plant is extinct if it no longer occurs anywhere. A plant that is extirpated from California has been eliminated from California but may still occur elsewhere in its range. All of the plants constituting California Rare Plant Rank 1A meet the definitions of the California Endangered Species Act of the California Department of Fish and Game Code and are eligible for state listing. Should these taxa be rediscovered, and impacts proposed to individuals or their habitat, they must be analyzed during preparation of environmental documents relating to the California Environmental Quality Act (CEQA), or those considered to be functionally equivalent to CEQA, as they meet the definition of Rare or Endangered under CEQA Guidelines §15125 (c) and/or §15380. BIOLOIGCAL RESOURCES SURVEY OF 830 ORCUTT ROAD, SAN LUIS OBISPO, CA 33 California Rare Plant Rank 1B: Plants Rare, Threatened, or Endangered in California and Elsewhere Plants with a California Rare Plant Rank of 1B are rare throughout their range with the majority of them endemic to California. Most of the plants that are ranked 1B have declined significantly over the last century. California Rare Plant Rank 1B plants constitute the majority of taxa in the CNPS Inventory, with more than 1,000 plants assigned to this category of rarity. All of the plants constituting California Rare Plant Rank 1B meet the definitions of the California Endangered Species Act of the California Department of Fish and Game Code and are eligible for state listing. Impacts to these species or their habitat must be analyzed during preparation of environmental documents relating to CEQA, or those considered to be functionally equivalent to CEQA, as they meet the definition of Rare or Endangered under CEQA Guidelines §15125; (c) and/or §15380. California Rare Plant Rank 2A: Plants Presumed Extirpated in California, But Common Elsewhere Plants with a California Rare Plant Rank of 2A are presumed extirpated because they have not been observed or documented in California for many years. This list only includes plants that are presumed extirpated in California, but more common elsewhere in their range. All of the plants constituting California Rare Plant Rank 2A meet the definitions of the California Endangered Species Act of the California Department of Fish and Game Code and are eligible for state listing. Should these species be rediscovered, any impacts proposed to individuals or their habitat must be analyzed during preparation of environmental documents relating to CEQA, or those considered to be functionally equivalent to CEQA, as they meet the definition of Rare or Endangered under CEQA Guidelines §15125 (c) and/or §15380. California Rare Plant Rank 2B: Plants Rare, Threatened, or Endangered in California, But More Common Elsewhere Except for being common beyond the boundaries of California, plants with a California Rare Plant Rank of 2B would have been ranked 1B. From the federal perspective, plants common in other states or countries are not eligible for consideration under the provisions of the Federal Endangered Species Act. With California Rare Plant Rank 2B, we recognize the importance of protecting the geographic range of widespread species. In this way we protect the diversity of our own state's flora and help maintain evolutionary processes and genetic diversity within species. All of the plants constituting California Rare Plant Rank 2B meet the definitions of the California Endangered Species Act of the California Department of Fish and Game Code and are eligible for state listing. Impacts to these species or their habitat must be analyzed during preparation of environmental documents relating to CEQA, or those considered to be functionally equivalent to CEQA, as they meet the definition of Rare or Endangered under CEQA Guidelines §15125 (c) and/or §15380. California Rare Plant Rank 3: Plants About Which More Information is Needed - A Review List Plants with a California Rare Plant Rank of 3 are united by one common theme - we lack the necessary information to assign them to one of the other ranks or to reject them. Nearly all of the plants constituting California Rare Plant Rank 3 are taxonomically problematic. For each California Rare Plant Rank 3 plant we have provided the known information and indicated in the “Notes” section of the CNPS Inventory record where assistance is needed. Data regarding distribution, endangerment, ecology, and taxonomic validity are welcomed and can be submitted by emailing the Rare Plant Botanist at asims@cnps.org. All of the plants constituting California Rare Plant Rank 3 meet the definitions of the California Endangered Species Act of the California Department of Fish and Game Code and are eligible for state listing. Impacts to these species or their habitat must be analyzed during preparation of environmental documents relating to CEQA, or those considered to be functionally equivalent to CEQA, as they meet the definition of Rare or Endangered under CEQA Guidelines §15125 (c) and/or §15380. California Rare Plant Rank 4: Plants of Limited Distribution - A Watch List Plants with a California Rare Plant Rank of 4 are of limited distribution or infrequent throughout a broader area in California, and their status should be monitored regularly. Should the degree of endangerment or rarity of a California Rare Plant Rank 4 plant change, we will transfer it to a more appropriate rank. Some of the plants constituting California Rare Plant Rank 4 meet the definitions of the California Endangered Species Act of the California Department of Fish and Game Code, and few, if any, are eligible for state listing. Nevertheless, many of them are significant locally, and we strongly recommend that California Rare Plant Rank 4 plants be evaluated for impact significance during preparation of environmental documents relating to CEQA, or those considered to be functionally equivalent to CEQA, based on CEQA Guidelines §15125 (c) and/or §15380. This may be particularly appropriate for: • The type locality of a California Rare Plant Rank 4 plant, • Populations at the periphery of a species' range, • Areas where the taxon is especially uncommon, • Areas where the taxon has sustained heavy losses, or • Populations exhibiting unusual morphology or occurring on unusual substrates. Threat Ranks • 0.1-Seriously threatened in California (over 80% of occurrences threatened / high degree and immediacy of threat) • 0.2-Moderately threatened in California (20-80% occurrences threatened / moderate degree and immediacy of threat) • 0.3-Not very threatened in California (less than 20% of occurrences threatened / low degree and immediacy of threat or no current threats known) BIOLOIGCAL RESOURCES SURVEY OF 830 ORCUTT ROAD, SAN LUIS OBISPO, CA 34 California Dept. of Fish & Game Endangered Species (CE) Plant taxa whose prospects for survival are in immediate jeopardy from one or more causes Threatened Species (CT) Plant taxa not presently threatened with extinction, but likely to become endangered within the foreseeable future in the absence of special protection and management efforts Rare Species (CR) Plant taxa not presently threatened with extinction, but occurring in such small numbers throughout its range that they may become endangered if habitat conditions worsen State Ranking S1 = Less than 6 EOs or less than 1,000 individuals or less than 2,000 acres S2 = 6-20 EOs or 1,000–3,000 individuals or 2,000–10,000 acres S3 = 21-100 EOs or 3,000-10,000 individuals or 10,000-50,000 acres S4 = Apparently secure in California – No threat rank S5 = Demonstrably secure in California – No threat rank Number following S ranks: 1 – Very threatened 2 – Threatened 3 – No current threats U. S. Dept. of Fish and Wildlife Endangered Species (FE) Taxa in danger of extinction throughout all or a significant portion of their range Threatened Species (FT) Taxa likely to become endangered within the foreseeable future throughout all or a significant portion of their range Candidate Species (C) Taxa for which the Service has on file enough substantial information on biological vulnerability and threat (s) to support proposals to list them as endangered or threatened species, but such action has been delayed by other listing activity Global Ranking GX Presumed Extinct Believed to be extinct throughout its range. Not located despite intensive searches of historical sites and other appropriate habitat, and virtually no likelihood that it will be rediscovered. GH Possibly Extinct Known from only historical occurrences but may nevertheless still is extant; further searching needed. G1 Critically Imperiled Critically imperiled globally because of extreme rarity or because of some factor (s) making it especially vulnerable to extinction. Typically, 5 or fewer occurrences or very few remaining individuals (<1,000) or acres (<2,000) or linear miles (<10). G2 Imperiled Imperiled globally because of rarity or because of some factor (s) making it very vulnerable to extinction or elimination. Typically, 6 to 20 occurrences or few remaining individuals (1,000 to 3,000) or acres (2,000 to 10,000) or linear miles (10 to 50). G3 Vulnerable Vulnerable globally either because very rare and local throughout its range, found only in a restricted range (even if abundant at some locations), or because of other factors making it vulnerable to extinction or elimination. Typically, 21 to 100 occurrences or between 3,000 and 10,000 individuals. G4 Apparently Secure Uncommon but not rare (although it may be rare in parts of its range, particularly on the periphery), and usually widespread. Apparently not vulnerable in most of its range, but possibly cause for long-term concern. Typically, more than 100 occurrences and more than 10,000 individuals. G5 Secure Common, widespread, and abundant (although it may be rare in parts of its range, particularly on the periphery). Not vulnerable in most of its range. Typically, with considerably more than 100 occurrences and more than 10,000 individuals. T# Infraspecific Taxon (trinomial) The status of infraspecific taxa (subspecies or varieties) are indicated by a "T-rank" following the species' global rank. Rules for assigning T-ranks follow the same principles outlined above. For example, the global rank of a critically imperiled subspecies of an otherwise widespread and common species would be G5T1.

The special status wildlife species revealed in the nine-quadrangle search are listed in Table 8, Appendix 3. To generate this list, I referred to the most recent edition of the California Department of Fish and Game Natural Diversity Data Base (CNDDB) and other appropriate publications. A survey for special status wildlife species was conducted on the 0.57-acre lot and surrounding areas to determine actual and potential utilization of this site by wildlife species that have special listing. The project site is a developed, disturbed residential lot surrounded by commercial developments. Only a few wildlife species would be expected to use the subject lot. During my surveys no signs (scat, tracks, burrows, or live observations) of special status wildlife species were observed. For the most part, special status animal species that occur within the San Luis Obispo and surrounding quadrangles (Table 8; Appendix 3) are highly restricted both in distribution range and in habitat requirements and are not expected to occupy the urban habitats found on and around the subject lot. For example, some rare animal species occur in salt or brackish water, e.g., the Tidewater goby; some require permanent standing water, e.g., Steelhead; some occur in vernal pools, e.g., the fairy shrimp; some occur only in specific soils and or other substrate conditions, e.g., the globose dune beetle (fore dune sands) and Morro Bay shoulderband snail; some require specific roosting sites, e.g., the bat species; some require large, deep bodies of water, e.g., the western pond turtle and red-legged frogs; some require permanent standing water to lay their eggs; e.g. coast range newt. In addition, the site is simply out of the geographic range in which many special status species have been found, e.g., Atascadero June BIOLOIGCAL RESOURCES SURVEY OF 830 ORCUTT ROAD, SAN LUIS OBISPO, CA 47 beetle. None of the specialized habitats listed above occur on or near the subject lot. Invertebrates: There will be no impacts to the special status invertebrate species as a result of this subdivision. The special status species of mollusks, insects, and crustaceans listed from the San Luis Obispo and surrounding quadrangles (Table xxx) either do not have appropriate habitat on the study site, or the site is located out of their known ranges. The subject lot is out of range and does not have suitable habitats for the listed mollusks. The Morro Bay shoulderband snail is only known to occur in limited numbers on stabilized, vegetated, Flandrian and pre-Flandrian dunes in the general vicinity of Morro Bay and Los Osos, California. The San Luis Obispo pyra occurs in largely in brackish water, and the California brackish water snail only occurs in brackish water. No wetlands or brackish water habitats occur on the subject parcel. Fish: No fish were found on the subject lot. There will be no impacts to the special status fish species as a result of this subdivision. Steelhead is a species that is listed as threatened by the federal government. This fish occurs in well-vegetated stream margins, gravel bedded rivers and streams with shaded deep pools and perennial water available. Tidewater goby is a small fish found in brackish, shallow lagoons and lower stream reaches where water is relatively still. Monterey roach is a cyprinid fish that is mostly a bottom feeder on filamentous algae, aquatic insects, and crustaceans. They move into shallow, flowing water, over bottoms covered with small rocks, and form up into schools. The three-spined stickleback usually inhabits coastal waters or freshwater bodies. It can live in fresh, brackish, or salt water. It prefers slow-flowing water with areas of emerging vegetation. It can be found in ditches, ponds, lakes, backwaters, quiet rivers, sheltered bays, marshes, and harbors. Clearly the small ephemeral creek does not provide habitat for any of these fish. Amphibians: There will be no impacts to the special status amphibian species as a result of this subdivision. None of the special status species of amphibians were found or are expected to us the subject lot because of the absence of appropriate habitat, or the site is located out of their known ranges. These species are discussed in detail below. The U.S. Fish and Wildlife Service (USFWS) and a California Special Concern species by the California Department of Fish and Game (CDFG) list California red- legged frog (Rana aurora draytonii) as Threatened. California red-legged frogs (CRF hereafter) have historically been found in riparian habitats throughout the coastal areas of California and in some inland areas. They were likely widespread throughout San Luis Obispo County and were probably found in most streams with BIOLOIGCAL RESOURCES SURVEY OF 830 ORCUTT ROAD, SAN LUIS OBISPO, CA 48 permanent pools, as well as permanent ponds, lakes, and marshes. Unfortunately, today CRF have disappeared from almost all of its former range. Jennings and Hayes (1985) and Tatarian (2008) report that CRF typically occur in habitats with deep sheltered pools of water and stands of overhanging protective vegetation. Typha (cat-tails), Scripus (tules), and Salix (willows) are typically associated with the presence of CRF. Canopy cover keeps the water temperature low, which is a particularly important habitat requirement for CRF according to Hayes (1990). Accessibility to such habitat is important for the long-term survival of this species and can be a factor limiting population density and distribution. Even in intermittent stream habitats, CRF require pools of permanent standing water, usually 20 inches deep with dense shoreline or emergent vegetation. U.S. Fish and Wildlife Service (1996) found that incised stream channels with portions narrower and deeper than 18 inches also provide habitat for CRF. Other studies have found that individual CRF have been found using channels and pools of various depths; however minimum depths of at least 12 to 18 inches, generally from late spring to the fall, are required (M. Allaback , 2000). CRF usually occur in habitats that typically lack introduced bullfrogs, non-native fish, and other introduced predators and competitors (Hayes and Jennings 1989). According to Stebbins (1985) and Tatarian (2008) sufficient pond depth and emergent vegetation cover are both critical, because they offer means of escape from predators and provide vegetation areas to deposit eggs during the breeding season. Biological surveys of the creek channel and woodland areas on the subject property indicate that these habitat requirements for CRF do not exist on the site. The Designation of Critical Habitat for the CRF, as described by the USFWS (2006), consists of the following four main habitat elements. (1) For successful breeding and reproduction, the aquatic habitat must have a permanent water source that supports pools of water with a minimum depth of 20 inches (although this may vary now). These pools must be able to maintain water for the entire tadpole-rearing season, a minimum of 20 weeks. (2) The area must have a non- breeding aquatic habitat that provides food, space, and vegetative cover that is spatially distinct from breeding habitat. (3) The property must have upland areas (up to 300 feet from the water’s edge) that is associated with the aquatic habitat described above and provide shelter (i.e., boulders, rocks, trees, shrubs, or logs), forage, maintenance of the water quality, and dispersal areas. (4) The adjacent upland areas must also provide barrier-free dispersal habitat that is at least 300 feet wide. The upland area must also connect at least two (or more) suitable breeding habitats (as defined previously) that are within 1.25 miles of each other. The small ephemeral creek along the project site does not provide habitat for California red-legged frogs. BIOLOIGCAL RESOURCES SURVEY OF 830 ORCUTT ROAD, SAN LUIS OBISPO, CA 49 The Coast Range newt is a California species that occurs in wet forests, oak forests, chaparral, and rolling grasslands. It utilizes ponds, reservoirs, and pools in streams to breed, typically beginning in December or January or with the first heavy rains. Eggs are attached to submerged vegetation or stones. Larvae transform and begin to live on land at the end of the summer or in early fall. In summer they can be found in moist habitats under woody debris, or in rock crevices and animal burrows, but can also sometimes be seen wandering overland in moist habitats any time of the year. No appropriate habitats occur for this species on or near the project site. The small ephemeral creek does not provide habitat for the coast range newt. The California tiger salamander is a California species that is restricted to grasslands and low foothill regions (typically below 2000 feet but up to 3,500 in coastal areas). They occur and breed in natural ephemeral or vernal pools but also occur in seasonal ponds (e.g. stock ponds) that are allowed to go dry. In the Coastal region, California tiger salamanders occur in scattered populations from Sonoma County to Santa Barbara County. I found no vernal pools or ephemeral ponds on or near the home site. The small ephemeral creek does not provide habitat for the California tiger salamander. Arroyo toad occurs in washes, arroyos, sandy riverbanks, and riparian areas. It has extremely specialized habitat needs, which includes exposed sandy streamsides with scattered vegetation for shelter, stable terraces for burrowing, and still pools with no predatory fishes. For breeding, the arroyo toad requires still pools of water with sandy or gravel bottoms that have not been heavily silted. The arroyo toad was not found on or expected to use the subject site. The seasonal creek on site does not provide the specialized habitat required by this species and is not suitable for breeding. Lesser slender salamander is endemic to a small area in the southern Santa Lucia Mountains of San Luis Obispo County. It is found in moist locations above 1,300 ft. (400 m) in forests composed of mixed oak, tanbark oak, sycamore and laurel. It was not found on or expected to use the site subject site. The site is out of the known range of this species and is below 1,300 feet elevation. The San Simeon slender salamander is endemic to the Santa Lucia Range in southwestern Monterey and northern San Luis Obispo Counties. Its distribution is not well known, but it is found in habitats that range from open oak woodlands near the coast to closed-canopy forest including open yellow pine forest and the leaf- litter of laurel and sycamore woodland on Pine Mountain and Rocky Butte in northern San Luis Obispo County. This species was not found on the subject site, which is not within its known range, and it not expected to use the site. Western spadefoot occurs primarily in grassland habitats but can be found in oak woodlands, chenopod scrub, alkali sink, and in sandy, gravelly washes and river BIOLOIGCAL RESOURCES SURVEY OF 830 ORCUTT ROAD, SAN LUIS OBISPO, CA 50 floodplains. Must have vernal pools for breeding and egg lying. It was not found on or expected to use the seasonal creek on the subject lot. Foothill yellow-legged frog at one time was found from northern Oregon west of the Cascades south to the San Gabriel Mountains in southern California, and along the western side of the Sierra Nevada to the edge of the Tehachapi Mountains. However, it is now absent or very rare along the California coast south of Monterey County and only a few populations have survived in the foothills of the southern Sierra Nevada Mountains. Foothill yellow-legged frog habitats include streams and rivers with rocky substrate that traverse woodlands and forest and have exposed, open sunny banks. This species was not found on the subject site, which is not within its known range, and it not expected to use the ephemeral creek on the site. Reptiles: There will be no impacts to the special status reptile species as a result of this subdivision. The listed special status reptiles (Table 8) have no or very limited potential habitat on or around the subject lot; so, they are not expected to use the site. Black and silvery legless lizards typically occur in sand dunes along the coast where they are fairly common in sandy soils of Montana de Oro State Park, Los Osos, and Morro Bay. These species of legless lizards are adapted for burrowing in sandy or loamy soils but can also occur in leaf litter or under logs in moist environments. The ephemeral creek on the subject property is dry much of the year and does not provide suitable habitat for the legless lizards. Black and silvery legless lizards are found in somewhat similar habitats as the Coast Range newts, and neither of these occurs on the home site. The same is true for the two-stripped garter snake, which prefers moist habitats. It is highly unlikely that the two-stripped garter snake would utilize the creek. The subject lot and ephemeral creek does not provide habitat for the coast range newt The coast horned lizard is a California reptile species of concern whose populations are in decline. Historically, the horned lizard was found along the Pacific coast from Baja California north to the Bay Area, and inland as far north as Shasta Reservoir. This species also extends inland to the Kern Plateau east of the crest of the Sierra Nevada. However, its current range is more scattered and fragmented. Horned lizards are found in open areas of loose or sandy soil and low vegetation and have been found in various places in San Luis Obispo County. No horned lizards were observed during field surveys, and no habitat for this species was found on the project site. Western pond turtles require ponds, lakes, or deeper waters to avoid predators and to feed. They can live on land and will often travel overland in search of a source of water or a place to over summer in underground burrows in dry years. No appropriate aquatic or wetland habitats for western pond turtles occur on the project BIOLOIGCAL RESOURCES SURVEY OF 830 ORCUTT ROAD, SAN LUIS OBISPO, CA 51 site, and no signs of them were found. This species was not found on the subject site, and it not expected to use the ephemeral creek on the site. Birds: There will be no impacts to the special status bird species as a result of this subdivision. There are several special status bird species reported from the San Luis Obispo and surrounding quadrangles (Table 8) but most of them do not have appropriate habitats on or near the home site. For example, all of the shore birds and those associated with inland water sources, such as the gulls, rails, terns, plovers, pelicans, brants, herons, egrets, oystercatchers, and loons, would not be expected to use the subject site. In addition, condors could potentially do a rare fly over but this is unlikely and condors would not use the site as habitat. There are nine special status species of raptors reported from the San Luis Obispo and surrounding quadrangles (Table 8). Most raptors, such as the golden eagles, northern harriers, and bald eagles, hunt and forage in large open areas that are away from development; therefore, they would not use the subject site other than perhaps an occasional fly over. The subject lot is also not appropriate habitat for ospreys, which prefers habitats with open water or large streams. Coopers hawks and sharp shinned hawks may visit the general area around the site but are not expected to use the subject lot. The white-tailed kite might visit the general area occasionally or fly over the subject lot but are not expected to use it. In conclusion, I would not expect any of the listed special status raptors to utilize the subject lot other than perhaps an occasional fly by. The proposed project will not affect these species The two special status species of owls listed on Table 8 are not expected to utilize the subject site. Burrowing owls range from the Mississippi to the Pacific and from the Canadian Prairie Provinces into South America where they are found in dry, open areas such as grasslands, prairies, savannas, deserts, and farmlands. Burrowing owls gets their name because they live in underground burrows, which provide shelter and a permanent nesting site. Unlike other owls, burrowing owls are diurnal species that live in the ground utilizing the burrows of other burrowing animals. This species is most generally associated with interior habitats of eastern San Luis Obispo County (Carrizo plain, Elkhorn Plains, and Cuyama Valley) but occasionally are seen near the coast. Occurrence of this species along the coast is most generally expected along the northern county coast (Cambria area) and even then occurrence is rare. There are no signs of burrowing owl activity on the subject lot and they would not be expected on or near the site. Burrowing owls prefer open areas with low ground cover and would not use the area on or immediately around the subject lot. The proposed project will not affect burrowing owls. California spotted owls occur in densely forested habitats. They are considered a BIOLOIGCAL RESOURCES SURVEY OF 830 ORCUTT ROAD, SAN LUIS OBISPO, CA 52 resident species and bellwether species of old-growth forests. California spotted owls nest in old abandoned nests of birds of prey, in tree holes, and sometimes in rock crevices. They are nocturnal owls that feeds on small mammals and birds. The forested habitat used by this species does not exist on the study site. The proposed project will not affect the spotted owl. A large number of special status passerine birds have been reported from the San Luis Obispo and surrounding quadrangles (Table 9), but most would not find appropriate habitats on the subject parcel. For example, tricolored blackbirds are found in western coastal North America where they are native to California and parts of Oregon, Washington, and Nevada. The largest populations are found in the San Joaquin Valley of California, as well as coastal areas. Tricolored blackbirds are typically found in freshwater marsh areas that have dense growths of cattails, bulrushes, and tules. This vegetation provides nesting and foraging sites. The tricolored blackbird populations have declined by over 80% in the last 80 years and may continue to decline as a result of continued habitat loss and disturbance in colonies established in agricultural fields of California (especially the San Joaquin Valley). Currently, over 40% of the world’s population nests in agricultural fields of the San Joaquin Valley, which are continuing to disappear or be disturbed. No appropriate aquatic or wetland habitats for this species occur on and near the project site. The proposed project will not affect this species. Western yellow-billed cuckoo was once common along the streams and rivers of the American West including California but is now a candidate for protection under the Endangered Species Act. Most of the remaining breeding pairs are found in Arizona, California, and New Mexico. Yellow-billed cuckoos prefer open woodlands with clearings and dense, low vegetation. No western yellow-billed cuckoos were observed on or near the study site, and no appropriate habitat for this species occurs on or near the subject lot. The proposed project will not affect the western yellow-billed cuckoo. California horned lark is a species of concern that occupies coastal plains, open fields, and grasslands from Sonoma County to San Diego County. It is also occupies most of the San Joaquin Valley. In San Luis Obispo County, horned larks occur primarily in open fields, short-grass grasslands, rangelands, saltbush scrub, and salt flats (e.g. Carrizo Plain). Grasses, shrubs, forbs, rocks, litter, clods of soil, and other surface irregularities provide cover. No signs of California horned larks were found on the project site, and no appropriate habitat conditions are present on the home site. The proposed project will not affect the California horned lark. The grasshopper sparrow prefers large open expanses of grassland often near water sources. This property lacks a permanent source of water. No signs of the grasshopper sparrow were found on the project site, and it is highly unlikely that this species will use the study site. No grassland habitats occur on the project site. The proposed project will not affect the grasshopper sparrow. BIOLOIGCAL RESOURCES SURVEY OF 830 ORCUTT ROAD, SAN LUIS OBISPO, CA 53 Oak titmouse is almost entirely restricted to the dry slopes of California that surround the central San Joaquin Valley. This species prefers open woodlands of warm, dry oak and oak-pine at low to mid-elevations but can also be found in forests as long as adequate oak trees are present. This species was not found on subject site. There is no suitable habitat for the oak titmouse on the project site. I would not expect this species to use the subject site. Vaux’s swift is found in habitats that include old growth coniferous or deciduous forests. Vaux's Swifts typically nest in old growth forests in hollow tree snags. This species was not found on or expected to use the subject site. No old growth or appropriate forest habitats are present on the subject site. American Bittern is mostly a coastal species, which is a common winter visitor to coastal freshwater marshes that contain dense cattails or bulrushes and is also a rare or irregular visitor to the salt marshes of Morro Bay. This species was not found on or expected to use the subject site. No suitable wetland habitats occur on site for this species. Purple martin is a species of concern in California and is often in association with human settlement. Their breeding habitat is throughout temperate North America in open areas across eastern North America, and also some locations on the west coast from British Columbia to Mexico. Purple martins are insectivores and are attracted to the large populations of insects that occur near wetlands; therefore, they prefer open spaces that are situated close to bodies of water. Due to urban development and human interactions in their natural habitats, purple martins are now accustomed to human interaction and live in close proximity with humans today. They tend to find shelter in urban areas where humans put in birdhouse specifically for purple martin’s nests. They are usually absent from areas where no such nest sites are provided. Historically, this species inhabited forest edges, montane forests, and deserts and nested in abandoned woodpecker cavities. Some populations that breed in the western United States continue to live in these natural settings, however, most utilize human-made birdhouses. Purple martins were not observed on the site or expected to use the subject site. The lark sparrow is a common bird in the United States and southern Canada. These birds forage on the ground or in low bushes. They mainly eat seeds but also prey on insects, including grasshoppers, in the breeding season. They will breed in a variety of open habitats including grasslands and cultivated areas. They nest on the ground close to clumps of grass or other vegetation. No habitat for lark sparrows occurs on the project site. Belding’s savanna sparrows are one of seventeen subspecies of savanna sparrows. These birds forage on the ground or in low bushes, particularly in winter when they are also found in grazed, low-growth grassland. They mainly eat seeds, but also eat insects in the breeding season. They are typically encountered as pairs or family groups in the breeding season and assemble in flocks for winter migration. BIOLOIGCAL RESOURCES SURVEY OF 830 ORCUTT ROAD, SAN LUIS OBISPO, CA 54 Belding’s savanna sparrows were not found on or near the study site as no suitable habitat occurs. The southern California rufus-crowned sparrow habitat includes moderate to steep, dry, rocky slopes vegetated with low growing scattered shrubs interspersed with patches of grasses and forbs or rock outcrops. This sparrow often occurs in coastal scrub dominated by Artemisia californica (California sagebrush) but also may occur in coastal bluff scrub, low chaparral on serpentine outcrops, sparse chaparral recovering from a burn, and edges of tall chaparral. It is generally absent from dense, unbroken stands of coastal scrub and chaparral. Nests are on the ground at the base of rocks, grass tufts, or saplings, or may be 0.3-1 meters above ground in the branches of shrubs or trees. There is no suitable habitat for the southern California rufus-crowned sparrow on the project site. Lawrence gold finches nest along the central and southern California coastal ranges, the Sierra Nevada foothills, and into Baja California. They overwinter in the deserts of southern Arizona. The typical nesting habitat is dry and open woodlands that are near both brushy areas and grassy fields, and usually within 0.5 mi (0.80 km) of a small body of water. This species may nest in other habitats, including rural residential areas, but not in deserts or dense forests. Outside the nesting season it occurs in many open habitats including deserts, suburbs, and city parks. There is no suitable habitat for Lawrence gold finches on the project site. Loggerhead shrikes are often found in open pastures or grasslands and appear to prefer trees like red cedar and hawthorn trees for nesting. The hawthorn’s thorns and the cedar’s pin-like needles protect and conceal the shrike from predators. Loggerhead shrikes may also nest in fencerows or hedgerows near open pastures. They require elevated perches as lookout points for hunting, and they forage in adjacent open pastures and grasslands with shorter vegetation. The shorter vegetation increases their hunting efficiency while taller vegetation often requires more time and energy to search for prey. As a result, these birds gravitate towards areas of shorter vegetation. They are also more common in large areas of grassland and oak savannas. There is no appropriate habitat for loggerhead shrike on the project site. Impacts to nesting birds during future project development need to be considered; however, the construction of the home should not impact any special status and other bird species that are protected by the Migratory Bird Treaty Act (MBTA) and/or California Fish and Game Code. Mammals: There will be no impacts to the special status mammal species as a result of this subdivision. There is no or very limited use of the subject site by mammals largely because the site is highly disturbed, has continuous human activity, and does not provide suitable habitat. I found nothing in the way of trails, scat, or diggings to suggest that BIOLOIGCAL RESOURCES SURVEY OF 830 ORCUTT ROAD, SAN LUIS OBISPO, CA 55 small mammals use the subject lot area. There will be no significant negative impacts to the mammals that currently use the habitats near the lot. Most of the special status mammals reported from the San Luis Obispo and surrounding quadrangles (Table 9), have specialized habitat requirements that are not present on the subject parcel. For example, there are obviously no appropriate habitats for marine mammals such as northern fur seals and Steller sea lions. Other mammals such as the Morro Bay kangaroo rat have specialized habitat needs as well as highly restricted ranges. Morro Bay kangaroo rats, which are believed to be extirpated, only occur in the Baywood fine sands with coastal dune scrub vegetation found around Morro Bay, Los Osos, and Montana de Oro State Park . No Morro Bay kangaroo rats have been found since the 1980s. Clearly no habitat for this species occurs on the subject parcel. No wood rat nests were observed on or near the property and no potential wood rat habitats will be affected by the proposed project. The American badger is a species of special concern in California that inhabits the western United States. Badgers are largely solitary and almost entirely nocturnal, foraging at night and then remaining underground during the daylight hours. It would be a vagrant that moved across the landscape, digging a new burrow every day or two. Badgers can be found in grasslands where they often dig burrows and forage for small mammals and reptiles; however, badgers can also visit a variety of habitats. No signs of badgers were observed, and no diggings or burrows were found. There is not suitable habitat for badgers on the subject lot. No bat species were observed on or near the home site and no habitat for these bats was found on the site. There is a remote possibility that Pallid bats, Townsend’s big-eared bats, big free-tailed bats, western mastiff bat, big free-tailed bats, California leaf-nosed bat and/ or Yuma bats might find habitat somewhere on the hills in the general vicinity of the project site but they are not expected to use the subject lot. The proposed project will not impact any special status bat species. BIOLOIGCAL RESOURCES SURVEY OF 830 ORCUTT ROAD, SAN LUIS OBISPO, CA 56 APPENDIX 3.
