Biological Resources Assessment for the 1434 Grove Street Project
1.0 INTRODUCTION
At the request of the City of Healdsburg, ECORP Consulting, Inc. conducted a biological resources assessment (BRA) for the ±1.839-acre Industrial 1434 Grove Street Project (Project) located in the City of Healdsburg, Sonoma County, California. The purpose of the assessment was to collect information on the biological resources present or with the potential to occur in the Project Study Area, assess potential biological impacts related to Project activities, and identify potential mitigation measures to inform and support the Project’s California Environmental Quality Act (CEQA) documentation for biological resources.
1.1 Project Location and Description
The Project is located east of Highway 101 at 1434 Grove Street, north of Dry Creek Road and adjacent to Foss Creek (Figure 1. Project Location and Vicinity). The site corresponds to an unsectioned portion of the Rancho Sotoyome Land Grant within the “Geyserville” and “Jimtown”, California” 7.5-minute quadrangles (U.S. Geological Survey [USGS] revised 1997; 1993, respectively). The approximate center of the site is located at latitude 38.629284° (NAD27) and longitude -122.874841° (NAD27) within the Russian Watershed (Hydrologic Unit Code #18010110) Watershed (Natural Resources Conservation Service [NRCS], et al. 2017).
The Project parcel (Assessor’s Parcel Number 089-071-012) is located within the ‘I’ (Industrial) land use designation in the Healdsburg 2030 General Plan and in the ‘I’ (Industrial) zoning district. The Project includes construction of a new one-story, 15,424-square foot building for industrial uses, a covered masonry trash enclosure, construction of a driveway and an uncovered parking lot, and construction of a bioretention basin. The Project site includes a portion of Foss Creek along the western boundary that will not be impacted by the proposed Project.
1.2 Purpose of this Biological Resources Assessment
The purpose of this BRA is to assess the potential for occurrence of special-status plant and animal species and their habitats and sensitive habitats such as wetlands and riparian communities within the Project Study Area. This assessment includes a preliminary analysis of impacts on biological resources anticipated to result from the Project as presently defined. The mitigation recommendations presented in this assessment are based on a preliminary impact analysis, a review of existing literature, and the results of the site reconnaissance, the aquatic resources delineation, and the early season rare plant surveys for the Project.

For the purposes of this assessment, special-status species are defined as plants or animals that:
are listed, proposed for listing, or candidates for future listing as threatened or endangered under the federal Endangered Species Act (ESA);
are listed or candidates for future listing as threatened or endangered under the California ESA;
meet the definitions of endangered or rare under § 15380 of the CEQA Guidelines;
are identified as a species of special concern (SSC) by the California Department of Fish and Wildlife (CDFW);
are birds identified as birds of conservation concern (BCC) by the U.S. Fish and Wildlife Service (USFWS);
are considered by the California Native Plant Society (CNPS) to be "rare, threatened, or endangered in California", “plants about which more information is needed”, or “plants of limited distribution – a watch list” (i.e., species with a California Rare Plant Rank [CRPR] of 1B, 2, 3, or 4);
are plants listed as rare under the California Native Plant Protection Act (NPPA) (California Fish and Game Code, § 1900 et seq.); or
are fully protected in California in accordance with the California Fish and Game Code, §§ 3511 (birds), 4700 (mammals), 5050 (amphibians and reptiles), and 5515 (fishes).
2.0 REGULATORY SETTING
2.1 Federal Regulations
2.1.1 Endangered Species Act
The ESA protects plants and animals that are listed as endangered or threatened by USFWS and the National Marine Fisheries Service (NMFS). Section 9 of ESA prohibits, without authorization, the taking of listed wildlife, where take is defined as “harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, collect, or attempt to engage in such conduct” [50 Code of Federal Regulations (CFR) 17.3]. For plants, this statute governs removing, possessing, maliciously damaging, or destroying any listed plant under federal jurisdiction and removing, cutting, digging up, damaging, or destroying any listed plant in any other area in knowing violation of state law [16 U.S. Code (USC) 1538].
Under Section 7 of ESA, federal agencies are required to consult with USFWS and/or NMFS if their actions, including permit approvals and funding, could adversely affect a listed (or proposed) species (including plants) or its critical habitat. Through consultation and the issuance of a biological opinion (BO), USFWS and NMFS may issue an incidental take statement allowing take of the species that is incidental to an otherwise authorized activity provided the activity will not jeopardize the continued existence of the species. Section 10 of ESA provides for the issuance of incidental take permits where no other federal actions are necessary provided a habitat conservation plan is developed.
ECORP Consulting, Inc. August 20, 2019 3 1434 Grove Street Project 2019-040
Biological Resources Assessment for the 1434 Grove Street Project
Section 7 Consultation
Section 7 of ESA mandates that all federal agencies consult with USFWS and/or NMFS to ensure that federal agencies’ actions do not jeopardize the continued existence of a listed species or adversely modify critical habitat for listed species. If direct and/or indirect effects will occur to critical habitat that appreciably diminish the value of critical habitat for both the survival and recovery of a species, the adverse modifications will require formal consultation with USFWS or NMFS. If adverse effects are likely, the federal lead agency must prepare a biological assessment (BA) for the purpose of analyzing the potential effects of the proposed project on listed species and critical habitat to establish and justify an "effect determination." Often a third-party, non-federal applicant drafts the biological assessment for the lead federal agencies. The USFWS/NMFS reviews the BA; if it concludes that the project may adversely affect a listed species or its habitat, it prepares a BO. The BO may recommend "reasonable and prudent alternatives" to the project to avoid jeopardizing or adversely modifying habitat.
Critical Habitat
Critical Habitat is defined in Section 3 of ESA as:
1. the specific areas within the geographical area occupied by a species, at the time it is listed in accordance with the ESA, on which are found those physical or biological features essential to the conservation of the species and that may require special management considerations or protection; and
2. specific areas outside the geographical area occupied by a species at the time it is listed, upon a determination that such areas are essential for the conservation of the species.
For inclusion in a Critical Habitat designation, habitat within the geographical area occupied by the species at the time it was listed must first have features essential to the conservation of the species (16 USC 1533). Critical Habitat designations identify, to the extent known and using the best scientific data available, habitat areas that provide essential life cycle needs of the species (areas on which are found the primary constituent elements). Primary constituent elements are the physical and biological features that are essential to the conservation of the species and that may require special management considerations or protection. These include but are not limited to the following:
1. Space for individual and population growth and for normal behavior
2. Food, water, air, light, minerals, or other nutritional or physiological requirements
3. Cover or shelter
4. Sites for breeding, reproduction, or rearing (or development) of offspring
5. Habitats that are protected from disturbance or are representative of the historic, geographical, and ecological distributions of a species

2.1.2 Migratory Bird Treaty Act
The Migratory Bird Treaty Act (MBTA) implements international treaties between the United States and other nations devised to protect migratory birds, any of their parts, eggs, and nests from activities such as hunting, pursuing, capturing, killing, selling, and shipping, unless expressly authorized in the regulations or by permit. As authorized under the MBTA, USFWS issues permits to qualified applicants for the following types of activities: falconry, raptor propagation, scientific collecting, special purposes (rehabilitation, education, migratory game bird propagation, and salvage), take of depredating birds, taxidermy, and waterfowl sale and disposal. The regulations governing migratory bird permits can be found in 50 CFR part 13 General Permit Procedures and 50 CFR part 21 Migratory Bird Permits. The State of California has incorporated the protection of non-game birds in § 3800, migratory birds in § 3513, and birds of prey in § 3503.5 of the California Fish and Game Code.
2.1.3 Clean Water Act
The purpose of the federal Clean Water Act (CWA) is to “restore and maintain the chemical, physical, and biological integrity of the nation’s waters.” Section 404 of the CWA prohibits the discharge of dredged or fill material into Waters of the United States without a permit from the USACE. The definition of Waters of the U.S. includes rivers, streams, estuaries, the territorial seas, ponds, lakes, and wetlands. Wetlands are defined as those areas “that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions” [33 CFR 328.3 7b]. The U.S. Environmental Protection Agency (USEPA) also has authority over wetlands, including the authority to veto permits issued by USACE under CWA Section 404(c).
Projects involving activities that have no more than minimal individual and cumulative adverse environmental effects may meet the conditions of one of the Nationwide Permits already issued by USACE (Federal Register [FR] 82:1860, January 6, 2017). If impacts on wetlands could be substantial, an individual permit is required. A Water Quality Certification or waiver pursuant to Section 401 of the CWA is required for Section 404 permit actions; this certification or waiver is issued by the Regional Water Quality Control Board (RWQCB).
U.S. Fish and Wildlife Service Birds of Conservation Concern
The 1988 amendment to the Fish and Wildlife Conservation Act mandates USFWS “identify species, subspecies, and populations of all migratory nongame birds that, without additional conservation actions, are likely to become candidates for listing under ESA.” To meet this requirement, USFWS published a list of BCC (USFWS 2008) for the United States. The list identifies the migratory and nonmigratory bird species (beyond those already designated as federally threatened or endangered) that represent USFWS’ highest conservation priorities. Depending on the policy of the lead agency, projects that result in substantial impacts to BCC may be considered significant under CEQA.

2.2 State and Local Regulations
2.2.1 California Endangered Species Act
The California ESA (California Fish and Game Code §§ 2050-2116) protects species of fish, wildlife, and plants listed by the state as endangered or threatened. Species identified as candidates for listing may also receive protection. Section 2080 of the California ESA prohibits the taking, possession, purchase, sale, and import or export of endangered, threatened, or candidate species, unless otherwise authorized by permit. Take is defined in Section 86 of the California Fish and Game Code as “hunt, pursue, catch, capture, or kill, or attempt to hunt, pursue, catch, capture, or kill.” The California ESA allows for take incidental to otherwise lawful projects under permits issued by CDFW.
Fully Protected Species
The State of California first began to designate species as “fully protected” prior to the creation of the federal and the California ESAs. Lists of fully protected species were initially developed to provide protection to those animals that were rare or faced possible extinction and included fish, amphibians and reptiles, birds, and mammals. Most fully protected species have since been listed as threatened or endangered under the federal and/or California ESAs. Fully protected species are identified in the California Fish and Game Code § 4700 for mammals, § 3511 for birds, § 5050 for reptiles and amphibians, and § 5515 for fish.
These sections of the California Fish and Game Code provide that fully protected species may not be taken or possessed at any time, including prohibition of CDFW from issuing incidental take permits for fully protected species under the California ESA. CDFW will issue licenses or permits for take of these species for necessary scientific research or live capture and relocation pursuant to the permit and may allow incidental take for lawful activities carried out under an approved Natural Community Conservation Plan within which such species are covered.
2.2.2 Native Plant Protection Act
The NPPA of 1977 (California Fish and Game Code §§ 1900-1913) was established with the intent to “preserve, protect and enhance rare and endangered plants in this state.” The NPPA is administered by CDFW. The Fish and Game Commission has the authority to designate native plants as “endangered” or “rare”. The NPPA prohibits the take of plants listed under the NPPA, but the NPPA contains a number of exemptions to this prohibition that have not been clarified by regulation or judicial rule. In 1984, the California ESA brought under its protection all plants previously listed as endangered under NPPA. Plants listed as rare under NPPA are not protected under the California ESA, but are still protected under the provisions of NPPA. The Fish and Game Commission no longer lists plants under NPPA, reserving all listings to the California ESA.
2.2.3 California Fish and Game Code Special Protections for Birds
In addition to protections contained within the California ESA and California Fish and Game Code § 3511 described above, the California Fish and Game Code includes a number of sections that specifically protect certain birds.
ECORP Consulting, Inc. August 20, 2019 6 1434 Grove Street Project 2019-040
Biological Resources Assessment for the 1434 Grove Street Project
Section 3800 states that it is unlawful to take nongame birds, such as those occurring naturally in California that are not resident game birds, migratory game birds, or fully protected birds, except when in accordance with regulations of the California Fish and Game Commission or a mitigation plan approved by CDFW for mining operations.
Section 3503 prohibits the take, possession, or needless destruction of the nest or eggs of any bird.
Section 3503.5 protects birds of prey (which includes eagles, hawks, falcons, kites, ospreys, and owls) and prohibits the take, possession, or destruction of any birds and their nests
Section 3505 makes it unlawful to take, sell, or purchase egrets, ospreys, and several exotic nonnative species, or any part of these birds.
Section 3513 specifically prohibits the take or possession of any migratory nongame bird as designated in the MBTA.
2.2.4 Lake or Streambed Alteration Agreements
Section 1602 of the California Fish and Game Code requires individuals or agencies to provide a Notification of Lake or Streambed Alteration to CDFW for “any activity that may substantially divert or obstruct the natural flow or substantially change the bed, channel, or bank of any river, stream, or lake.” CDFW reviews the proposed actions and, if necessary, proposed measures to protect affected fish and wildlife resources. The final proposal mutually agreed upon by CDFW and the applicant is the Lake or Streambed Alternation Agreement.
2.2.5 Porter-Cologne Water Quality Act
The RWQCB implements water quality regulations under the federal CWA and the Porter-Cologne Water Quality Act. These regulations require compliance with the National Pollutant Discharge Elimination System (NPDES), including compliance with the California Storm Water NPDES General Construction Permit for discharges of stormwater runoff associated with construction activities. General Construction Permits for projects that disturb one or more acres of land require development and implementation of a Storm Water Pollution Prevention Plan. Under the Porter-Cologne Water Quality Act, the RWQCB regulates actions that would involve “discharging waste, or proposing to discharge waste, with any region that could affect the water of the state” [Water Code 13260(a)]. Waters of the State are defined as “any surface water or groundwater, including saline waters, within the boundaries of the state” [Water Code 13050 (e)]. The RWQCB regulates all such activities, as well as dredging, filling, or discharging materials into Waters of the State, that are not regulated by USACE due to a lack of connectivity with a navigable water body. The RWQCB may require issuance of a Waste Discharge Requirements for these activities.
2.2.6 California Environmental Quality Act
In accordance with CEQA Guidelines § 15380, a species or subspecies not specifically protected under the federal or California ESAs or NPPA may be considered endangered, rare, or threatened for CEQA review purposes if the species meets certain criteria specified in the Guidelines. These criteria include definitions similar to definitions used in ESA, the California ESA, and NPPA. Section 15380 was included in the CEQA
ECORP Consulting, Inc. August 20, 2019 7 1434 Grove Street Project 2019-040
Biological Resources Assessment for the 1434 Grove Street Project
Guidelines primarily to address situations in which a project under review may have a significant effect on a species that has not been listed under ESA, the California ESA, or NPPA, but that may meet the definition of endangered, rare, or threatened. Animal species identified as SSC by CDFW and plants identified by the CNPS as rare, threatened, or endangered may meet the CEQA definition of rare or endangered.
Species of Special Concern
SSC are defined by the CDFW as a species, subspecies, or distinct population of an animal native to California that are not legally protected under ESA, the California ESA, or the California Fish and Game Code, but currently satisfies one or more of the following criteria:
The species has been completely extirpated from the state or, as in the case of birds, it has been extirpated from its primary seasonal or breeding role;
The species is listed as federally (but not state) threatened or endangered, or meets the state definition of threatened or endangered but has not formally been listed;
The species has or is experiencing serious (noncyclical) population declines or range retractions (not reversed) that, if continued or resumed, could qualify it for state threatened or endangered status;
The species has naturally small populations that exhibit high susceptibility to risk from any factor that if realized, could lead to declines that would qualify it for state threatened or endangered status, and
SSC are typically associated with habitats that are threatened.
Depending on the policy of the lead agency, projects that result in substantial impacts to SSC may be considered significant under CEQA.
California Rare Plant Ranks
The CNPS maintains the Inventory of Rare and Endangered Plants of California (CNPS 2019), which provides a list of plant species native to California that are threatened with extinction, have limited distributions, and/or low populations. Plant species meeting one of these criteria are assigned to one of six CRPRs. The rank system was developed in collaboration with government, academia, non- governmental organizations, and private sector botanists, and is jointly managed by CDFW and the CNPS. The CRPRs are currently recognized in the California Natural Diversity Database (CNDDB). The following are definitions of the CNPS CRPRs:
Rare Plant Rank 1A – presumed extirpated in California and either rare or extinct elsewhere
Rare Plant Rank 1B – rare, threatened, or endangered in California and elsewhere
Rare Plant Rank 2A – presumed extirpated in California, but more common elsewhere
Rare Plant Rank 2B – rare, threatened, or endangered in California but more common elsewhere
ECORP Consulting, Inc. August 20, 2019 8 1434 Grove Street Project 2019-040
Biological Resources Assessment for the 1434 Grove Street Project
Rare Plant Rank 3 – a review list of plants about which more information is needed
Rare Plant Rank 4 – a watch list of plants of limited distribution
Additionally, CNPS has defined Threat Ranks that are added to the CRPR as an extension. Threat Ranks designate the level of threat on a scale of 1 through 3, with 1 being the most threatened and 3 being the least threatened. Threat Ranks are generally present for all plants ranked 1B, 2B, or 4, and for the majority of plants ranked 3. Plant species ranked 1A and 2A (presumed extirpated in California), and some species ranked 3, which lack threat information, do not typically have a Threat Rank extension. The following are definitions of the CNPS Threat Ranks:
Threat Rank 0.1 – Seriously threatened in California (over 80 percent of occurrences threatened/high degree and immediacy of threat)
Threat Rank 0.2 – Moderately threatened in California (20-80 percent occurrences threatened/moderate degree and immediacy of threat)
Threat Rank 0.3 – Not very threatened in California (<20 percent of occurrences threatened/low degree and immediacy of threat or no current threats known)
Factors, such as habitat vulnerability and specificity, distribution, and condition of occurrences, are considered in setting the Threat Rank; and differences in Threat Ranks do not constitute additional or different protection (CNPS 2019).
Depending on the policy of the lead agency, substantial impacts to plants ranked 1A, 1B, or 2, and 3 are typically considered significant under CEQA Guidelines § 15380. Significance under CEQA is typically evaluated on a case-by-case basis for plants ranked 4 and at the discretion of the CEQA lead agency.
California Environmental Quality Act Significance Criteria
Sections 15063-15065 of the CEQA Guidelines address how an impact is identified as significant. Generally, impacts to listed (rare, threatened, or endangered) species are considered significant. Assessment of "impact significance" to populations of non-listed species (e.g., SSC) usually considers the proportion of the species’ range that will be affected by a project, impacts to habitat, and the regional and population level effects.
Specifically, § 15064.7 of the CEQA Guidelines encourages local agencies to develop and publish the thresholds that the agency uses in determining the significance of environmental effects caused by projects under its review. However, agencies may also rely upon the guidance provided by the expanded Initial Study checklist contained in Appendix G of the CEQA Guidelines. Appendix G provides examples of impacts that would normally be considered significant.
An evaluation of whether or not an impact on biological resources would be substantial must consider both the resource itself and how that resource fits into a regional or local context. Substantial impacts would be those that would diminish, or result in the loss of, an important biological resource, or those that would obviously conflict with local, state, or federal resource conservation plans, goals, or regulations. Impacts are sometimes locally important but not significant under CEQA. The reason for this is that
ECORP Consulting, Inc. August 20, 2019 9 1434 Grove Street Project 2019-040
Biological Resources Assessment for the 1434 Grove Street Project although the impacts would result in an adverse alteration of existing conditions, they would not substantially diminish or result in the permanent loss of an important resource on a population-wide or region-wide basis.
2.2.7 City of Healdsburg General Plan 2030
The City of Healdsburg’s Natural Resources Element of their General Plan (City of Healdsburg 2015) provides goals, policies and measures to protect and improve the City’s natural resources including plant and wildlife resources. Goals that could pertain to biological resources within the Project include:
GOAL NR-A: Improve water quality and flows in the Russian River, Dry Creek and Foss Creek to protect the city’s water supply, recreation, fish and wildlife.
GOAL NR-B: Conservation and restoration of Healdsburg’s native plants and wildlife, ecosystems and waterways.
GOAL NR-C: Preservation and enhancement of Healdsburg’s natural setting.
GOAL NR-D: Maintenance of the economic viability of agriculture in the Healdsburg area while providing for the planned development of Healdsburg.
GOAL NR-E: Reduce greenhouse gas emissions and increase energy efficiency communitywide.
GOAL NR-F: Protection and improvement of air quality in the Healdsburg area.
GOAL NR-G: Continuation of existing mineral extraction activities in an environmentally-sensitive manner.
Policies and Implementation Measures for these goals are detailed in the Natural Resources Element of their General Plan (City of Healdsburg 2015).
3.0 METHODS
3.1 Literature Review
The following resources were reviewed to determine the special-status species that had been previously documented within or in the vicinity of the Project Study Area:
CDFW CNDDB data for the for the “Ukiah, California” 7.5-minute quadrangle and the nine surrounding USGS quadrangles (CDFW 2019);
USFWS list of species and other resources under the USFWS jurisdiction that are known or expected to be on or near the Project area (USFWS 2019a);
NMFS list of species and other resources under NMFS jurisdiction that are known or expected to be on or near the Project area (NMFS 2019a); and

Biological Resources Assessment for the 1434 Grove Street Project
CNPS’ electronic Inventory of Rare and Endangered Plants of California was queried for the “Geyserville and Jimtown, California” 7.5-minute quadrangles and the nine surrounding USGS quadrangles (CNPS 2019).
3.2 Field Surveys Conducted
ECORP senior biologist Tom Scofield conducted a reconnaissance-level site assessment on March 12, 2019. ECORP’s staff biologist, Clay DeLong, conducted an aquatic resources delineation and early season rare plant survey on April 23, 2019, and ECORP’s staff botanist, Casey Peters, conducted a late season rare plant survey on August 13, 2019. The findings of these surveys have been incorporated into this BRA.
An arborist survey was conducted for the Project site by James McNair and Associates and is summarized in an Arborist Report for the Project (McNair and Associates).
3.3 Special-Status Species Considered for the Project
Based on species occurrence information from the literature review and field observations, a list of special-status and CNDDB-tracked plant and animal species considered to have the potential to occur within the Project was generated and is summarized in Section 4.0. Each of the species that were considered as potentially occurring within the Project or vicinity was evaluated based on the following criteria:
Present - Species was observed during field surveys or is known to occur within the Project based on documented occurrences within the CNDDB or other literature.
Potential to Occur - Habitat (including soils and elevation requirements) for the species occurs within the Project.
Low Potential to Occur - Marginal or limited amounts of habitat occurs and/or the species is not known to occur within the vicinity of the Project based on CNDDB records and other available documentation.
Absent - No suitable habitat (including soils and elevation requirements) and/or the species is not known to occur within the vicinity of the Project based on CNDDB records and other documentation.
4.0 RESULTS
4.1 Site Characteristics and Land Use
The Project is located on level terrain and is situated at an elevational range between approximately 140 to 150 feet above mean sea level (msl). The Project site is currently unimproved and bordered by railroad tracks to the east, Foss Creek to the west, a recently constructed industrial building to the north, and undeveloped property to the south. The general vicinity of the Project is largely developed with industrial and commercial uses.

Biological Resources Assessment for the 1434 Grove Street Project
The site is located in the northern coast range subregion of the California Floristic Province (Baldwin et al. 2012). This area is characterized by a Mediterranean climate, which is comprised of hot and dry summer months and cold and wet winter months. The annual precipitation for Healdsburg is approximately 42.13 inches (with the wettest period during October-April), and average daily temperatures range from 47.2˚ - 73.7 ˚F(National Oceanic and Atmospheric Administration [NOAA] 2019). Representative site photographs are provided in Attachment A.
4.2 Vegetation Communities
The Project area includes a densely wooded oak woodland located along the riparian edge of Foss Creek on the west side of the Project. There is also a remnant portion of oak woodland on the eastern side of the Project adjacent to a railroad easement. The dominant tree species occurring onsite include coast live oak (Quercus agrifolia), valley oak (Quercus lobata), native willow (Salix laevigata, and nonnative plum (Prunus spp.).
The Project also includes patches of ruderal/nonnative grassland and weedy vegetation along the edges of the riparian area and existing gravel parking areas. Plants found in this habitat include wild oats (Avena fatua), mustard (Brassica sp.), ripgut brome (Bromus diandrus), yellow star-thistle (Centaurea solstitialis), filaree (Erodium botrys), and prickly lettuce (Lactuca serriola). Vegetation found in the riparian understory include many of the ruderal/nonnative grassland species described above and also included poison oak (Toxicodendron diversilobum), Himalayan blackberry (Rubus armeniacus), and fennel (Foeniculum vulgare).
The eastern boundary near the railroad easement supports seasonal wetlands associated with a drainage swale and low-lying depressional areas that pond water. Vegetation observed in these areas were largely comprised of species found in wetlands including Italian ryegrass (Festuca perennis), Mediterranean barley (Hordeum marinum ssp. gussoneanum), toad rush (Juncus bufonius), hairy hawkbit (Leontodon saxatilis), Himalayan blackberry, Carex species (sedge), and curly dock (Rumex crispus). A comprehensive list of all plant species encountered during field surveys of the Project is provided in Attachment B.
4.3 Soils
According to the Web Soil Survey (NRCS 2019), one soil unit, or type, has been mapped within the Project, (ZaA) Zamora silty clay loam, 0 to 2 percent slopes (Figure 2. Natural Resources Conservation Service Soil Types). A very small area of (210) urban land is mapped along the edge of the highway.

4.4 Potential Waters of the U.S.
A total of 0.129 acre of aquatic resources have been mapped within the Project Area (Table 1). A discussion of the aquatic resources is presented below, and aquatic resources delineation map is provided in Figure 3. Potential Waters of the U.S, which. included two types: seasonal wetland and perennial creek (Foss Creek). These features are described below.
Table 1. Potential Waters of the U.S.
Type Acreage1 Wetlands Seasonal Wetland Swale 0.002 Other Waters Perennial Creek (Foss Creek) 0.127 Total 0.129 1Acreages represent a calculated estimation and are subject to modification following the U.S. Army Corps of Engineers verification process.
4.4.1 Wetlands
Seasonal Wetland
Approximately 0.002 acre of seasonal wetland occurs within the Project along the eastern boundary (Figure 3). Seasonal wetlands are ephemerally wet due to accumulation of surface runoff and rainwater within low-lying areas. Inundation periods tend to be relatively short and they are commonly dominated by nonnative annual and sometimes perennial hydrophytic species.
4.4.2 Other Waters.
Perennial Creek (Foss Creek)
Approximately 0.127-acre of perennial creek (a portion of Foss Creek) occurs within the Project (Figure 3). Perennial creeks are characterized by year-round flows, The limits of this feature were delineated at the ordinary high-water mark, which was identified based on water marks, scour, shifts in vegetation, sediment deposits, and drift deposits. Foss Creek is primarily comprised of open water, with mature riparian occurring along the banks.
4.4.3 Wildlife
Wildlife use onsite is expected to be minimal due to the highly disturbed nature of the Project site, and close proximity to the surrounding developed areas. Bird species found within the Project site during this assessment included red-shouldered hawk (Buteo lineatus), common raven (Corvus corax), Anna’s hummingbird (Calypte anna) northern mockingbird (Mimus polyglottos), oak titmouse (Baeolophus inornatus), western bluebird (Sialia mexicana), black phoebe (Sayornis nigricans), European starling (Sturnus vulgaris), white-crowned sparrow (Zonotrichia leucophrys), yellow-rumped warbler (Setophaga coronata), and Brewer’s blackbird (Euphagus cyanocephalus).

4.5 Evaluation of Special-Status Species Identified in the Literature Search
There are no special-status species previously documented within the Project site boundaries (CDFW 2019, Attachment C), but 21 special-status species are known to occur within the vicinity of the Project (CDFW 2019, USFWS 2019a, CNPS 2019). These species are: Sonoma sunrise (Blennosperma bakeri), bristly sedge Carex comosa), Pappose tarplant (Centromadia parryi ssp. Parryi), dwarf downingia (Downingia pusilla), congested-headed hayfield tarplant (Hemizonia congesta ssp. Congesta), Burke’s goldfields (Lasthenia burkei), Sebastopol meadowfoam (Limnanthes vinculans), Baker’s navarretia (Navarretia leucocephala ssp. bakeri), marsh checkerbloom (Sidalcea oregana ssp. hydrophila), California freshwater shrimp (Syncaris pacifica), hardhead (Mylopharodon conocephalus), Coho salmon (Oncorhynchus kisutch), Chinook salmon (Oncorhynchus tshawytscha), Steelhead (Oncorhynchus mykiss irideus), California giant salamander (Dicamptodon ensatus), California red-legged frog (Rana draytonii), foothill yellow-legged frog (Rana boylii), North Western pond turtle (Emys marmorata), burrowing owl (Athene cunicularia), White- tailed kite (Elanus leucurus), and Pallid bat (Antrozous pallidus).
These species and other special-status species that were evaluated are presented in Table 2, which lists all of the special-status plants and wildlife species identified in the literature review as potentially occurring within the Project. Included in these tables are the listing status for each species, a brief habitat description, and a determination on the potential to occur within the Project site. Following the table are brief descriptions and discussions of each special-status species that have the potential to occur in the Project.
Several species came up in the database and literature searches (Attachment B) but are not included in Table 2 because they are only tracked by the CNDDB and possess no special status or because the identified sensitive habitats are not located within the Project area. They are not discussed further in this report.

Based on the literature review and habitat types recorded in the Project, nine special-status plant species were identified as having a low potential to occur within the Project (Table 1). Several species identified in the database search were determined to be absent due to the absence of suitable habitat and/or because the Project is outside the range of the species.
A focused early rare plant survey (conducted by ECORP on April 24, 2019) found no potentially occurring early season special-status plants. Accordingly, potentially occurring early blooming plant species including: bristly sedge, Pappose tarplant, dwarf downingia, congested-headed hayfield tarplant, Burke’s goldfield, Sebastopol meadowfoam, and Baker’s navarretia are considered not to occur in the Project.
A second focused late season rare plant survey will be conducted in June 2019 to address two potentially occurring late season blooming rare plant species: Sonoma sunrise and marsh checkerbloom.
4.5.2 Special-Status Animals
Based on the literature review and habitat types recorded in the Project, 12 of the 17 special-status animals are considered to potentially occur within the Project (Table 1).
Invertebrates
One special-status invertebrate (California freshwater shrimp [Syncaris pacifica]) is considered to potentially occur in Foss Creek.

California Freshwater Shrimp
The California fresh water shrimp is a small fresh water shrimp that occurs in a relatively small range of coastal low elevation, low gradient (low velocity) streams in central California. The species is known to occur in Napa, Sonoma, and Marin counties. Due to habitat loss and degradation in many parts of this coastal stream system and the limited range in which this species occurs, California fresh water shrimp is listed as endangered pursuant to both the federal and California ESAs. This species may occur onsite within Foss Creek.
Fish
Four of the special-status fish species identified in the literature search (hardhead (Mylopharadon conocephalus), Central California Coast Coho salmon, California Coastal Chinook salmon, and Central California Coast steelhead) potentially occur in the Project site in association with Foss Creek.
Hardhead
Hardhead is a relatively large minnow (Family Cyprinidae) that is a California SSC. Hardhead are widely distributed, but declining in abundance, in relatively undisturbed low- to mid-elevation streams throughout the Sacramento-San Joaquin river and Russian River drainages (Moyle 2002). Hardhead may reach lengths of 60 cm or greater (Moyle et al. 2015). Juvenile hardhead typically aggregate and forage at the surface of pools and runs during the day, while adults tend to occur in deeper pools where they forage on invertebrates and aquatic plants. The primary threats to hardhead include dams and diversions, agricultural practices, urbanization, instream mining, stream channel modifications, fisheries management (i.e., historic eradication and harvest as a “rough fish”), and competition from nonnative fish species (Moyle et al. 2015). Foss Creek provides potential habitat for supporting hardhead. Hardhead have the potential to occur within Foss Creek on the Project site.
Coho Salmon (Central California Coast ESU)
The Central California Coast (CCC) Evolutionarily Significant Unit (ESU) of Coho salmon (Oncorhynchus kisutch) was first listed as threatened under the ESA in 1996 (61 FR 56138) and subsequently listed as endangered under the ESA in 2005 (70 FR 37160). The CCC ESU was listed as endangered under the California ESA in March 2005. The CCC ESU includes populations from Punta Gorda, California south to the San Francisco Bay (excluding the Sacramento-San Joaquin river system). Critical Habitat was designated for the CCC ESU under the ESA on May 5, 1999 (64 FR 24049).
Coho salmon are anadromous salmonids, which spend the adult life stage in the ocean, and migrate into their natal freshwater rivers for spawning, egg incubation, and early life stage rearing. Adults enter freshwater to spawn in riffles of coastal streams from September through January. Eggs incubate in the gravel from November through April and alevins (hatchlings) remain within the gravels for two to 10 weeks until their yolk sac is absorbed. Fry emerge from the gravel from March to July and become parr (immature juveniles) over the summer months. After spending their first year rearing in their natal freshwater stream, Coho salmon smolts migrate to the ocean under winter flows in March and April. Adult Coho salmon typically spend two years in the ocean before returning to their natal streams to spawn. The primary threats to CCC ESU Coho salmon are largely human-related and include habitat loss, genetic
ECORP Consulting, Inc. August 20, 2019 27 1434 Grove Street Project 2019-040
Biological Resources Assessment for the 1434 Grove Street Project
introgression with hatchery-reared fish, overexploitation, and climactic changes (e.g., oceanic conditions) (Moyle 2002). Foss Creek provides potential habitat for supporting CCC ESU Coho salmon but is not designated Critical Habitat for the ESU. Coho salmon have the potential to occur within Foss Creek on the Project site.
Chinook Salmon (California Coastal ESU)
The California Coastal (CC) ESU of Chinook salmon includes naturally spawned populations from rivers south of the Klamath River to the Russian River. The CC ESU was first listed as threatened under the ESA in 1999 (64 FR 50394) and subsequently reaffirmed with the addition of hatchery stocks in 2005 (70 FR 37160). Critical habitat was designated for the CC ESU under the ESA on September 2, 2005 (70 FR 52488). The CC ESU is not listed under the California ESA, nor does it have a special-status designation in California.
Chinook salmon are anadromous salmonids. Adult CC ESU Chinook salmon spend three to five years in the ocean before entering freshwater to spawn in their natal streams from September through January. The timing of spawning and early life stage development is somewhat elastic and dependent upon annual, climatic, and hydrologic conditions. Spawning occurs in the late fall and early winter months and the adults die shortly after spawning. Eggs incubate in the gravel from approximately November through March and alevins (hatchlings) remain within the gravels for two to 10 weeks until their yolk sac is absorbed. Fry emerge from the gravel in late winter or early spring. Some portion of these fish may emigrate toward the ocean as post-emergent fry immediately after gravel emergence, or as smolts up to several weeks or months after emergence. The primary threats to CC ESU Chinook salmon are largely human-related and include habitat loss (e.g., due to dams and other migration barriers) and degradation, alteration of river flows, urbanization, gravel mining, and competition or predation from introduced species (Moyle 2002). Foss Creek provides potential habitat for supporting CC ESU Chinook salmon but is not designated Critical Habitat for the ESU. Chinook salmon have the potential to occur within Foss Creek on the Project site.
Steelhead (Central California Coast ESU)
Steelhead is the anadromous form of rainbow trout. The CCC ESU of steelhead includes populations from coastal streams extending from the Russian River to Aptos Creek, and drainages of San Francisco Bay, San Pablo Bay, and Suisun Bay eastward to Chipps Island, and tributary streams to Suisun Marsh. The CCC ESU was first listed as threatened under the ESA in 1997 (62 FR 43937) and subsequently reaffirmed 2006 (71 FR 834). Critical habitat was designated for the CC ESU under the ESA on September 2, 2005 (70 FR 52488). The CC ESU is not listed under the California ESA nor does it have a special-status designation in California.
Adult steelhead spend one to three years in the ocean before migrating back to their natal streams to spawn, typically from December through March. Spawning occurs shortly after arrival at suitable habitats in their natal stream and eggs incubate for three to four weeks. Fry emerge from the gravel within two to three weeks after hatching. Juveniles spend the first year or two residing in cool, fast-moving, and clear perennial streams before emigrating to the ocean under high winter flows. The primary threats to CCC ESU steelhead include overharvest, degradation and loss of estuarine habitat, hydropower development
ECORP Consulting, Inc. August 20, 2019 28 1434 Grove Street Project 2019-040
Biological Resources Assessment for the 1434 Grove Street Project
and associated dams, degraded ocean conditions, and hatchery practices (NMFS 2011). Foss Creek provides potential habitat for supporting CCC ESU steelhead but is not designated critical habitat for the ESU. Steelhead have the potential to occur within Foss Creek on the Project site.
Amphibians
Three special-status amphibian species: California giant salamander (Dicamptodon ensatus), California red- legged frog (Rana draytonii), and foothill yellow-legged frog (Rana boylii), potentially occur in the Project site in association with Foss Creek.
California Giant Salamander
The California giant salamander (Dicamptodon ensatus) is listed as federally endangered by the USFWS and is a California state listed endangered species. California giant salamander is a large (to 17 cm snout- vent length [snout-vent length), heavy-bodied salamander occurring in California’s mesic coast forests (Thomson et al. 2016). Adults are terrestrial most of the year, and are found under rocks, debris, bark, and other cover near streams. California giant salamanders occur in the Coast Range from the Point Arena vicinity of Mendocino County, east into Lake and Glenn counties, and south to Santa Cruz County. This species may occur onsite within and adjacent to Foss Creek.
California Red-legged Frog
The California red-legged frog (Rana draytonii) is listed as federally threatened by the USFWS and is a California SSC. Critical Habitat was designated pursuant to the ESA across approximately 1,636,609 acres in 27 counties including Alameda, Butte, Calaveras, Contra Costa, El Dorado, Marin, Napa, Nevada, Placer, Solano, and Yuba counties. The California red-legged frog range extends through Pacific slope drainages and parts of the Central Valley from Shasta County, California, to Baja, Mexico. This area includes the Coast Ranges and the west slope of the Sierra Nevada Mountains at elevations below 1,548 meters (5,000 feet). The current range is greatly reduced, with most remaining populations occurring along the coast from Marin County to Ventura County; and in isolated locations in the foothills of the western slope of the Sierra Nevada. Breeding habitat includes coastal lagoons, marshes, springs, permanent and semi- permanent natural ponds, and ponded and backwater portions of streams. California red-legged frogs also breed in artificial impoundments including stock ponds, irrigation ponds, and siltation ponds. Upland and riparian areas provide important habitat during summer when California red-legged frogs are known to aestivate in dense vegetation, burrows and leaf litter. California red-legged frogs often disperse from breeding habitats to forage and seek upland refugia and are often found within close proximity to a pond or deep pool in a creek where emergent vegetation, undercut banks, or semi-submerged rootballs afford shelter (USFWS 2005). This species may occur onsite within and adjacent to Foss Creek.
Foothill Yellow-Legged Frog
The foothill yellow-legged frog has been proposed for listing as threatened under California’s ESA and is a California SSC. It occurs in the Coast Ranges, from the Oregon border south to the Transverse Mountains in Los Angeles County, west of the Cascade crest in most of northern California, and in the Sierra Nevada foothills south to Kern County, from sea level to 6,000 feet above msl (Stebbins 1985). Foothill yellow-
ECORP Consulting, Inc. August 20, 2019 29 1434 Grove Street Project 2019-040
Biological Resources Assessment for the 1434 Grove Street Project
legged frogs occupy rocky streams in valley-foothill hardwood, valley-foothill hardwood-conifer, valley- foothill riparian, ponderosa pine, mixed conifer, coastal scrub, mixed chaparral, and wet meadow plant communities. They are rarely found far from water and will often dive into water to take refuge under rocks or sediment when disturbed (Zeiner et al. 1988). This species may occur onsite within and adjacent to Foss Creek.
Reptiles
One special-status reptile species, northern western pond turtle (Actinemys marmorata) was identified as potentially occurring in the Project site in association with Foss Creek.
Northern Western Pond Turtle
The northern western pond turtle is not listed pursuant to either the federal or California ESAs; however, it is designated as an SSC. Western pond turtles occur in a variety of fresh and brackish water habitats including marshes, lakes, ponds, and slow moving streams (Jennings and Hayes 1994). This species is primarily aquatic; however, they typically leave aquatic habitats in the fall to reproduce and to overwinter (Jennings and Hayes 1994). Deep, still water with abundant emergent woody debris, overhanging vegetation, and rock outcrops is optimal for basking and thermoregulation. Although adults are habitat generalists, hatchlings and juveniles and hatchlings require shallow edgewater with relatively dense submergent or short emergent vegetation in which to forage. Northern western pond turtles deposit their eggs within excavated nests in upland areas, with substrates that typically have high clay or silt fractions (Jennings and Hayes 1994). The majority of nesting sites are located within 200 meters (650 feet) of the aquatic sites; however, nests have been documented as far as 400 meters (1,310 feet) from the aquatic habitat. The CNDDB database includes known occurrences of northern western pond turtles within Foss Creek. This species is therefore considered to potentially occur onsite. This species may occur onsite within and adjacent to Foss Creek.
4.5.3 Birds
Two of the three of the special-status bird species identified in the literature search, Western white-tailed kite (Elanus leucurus) and burrowing owl (Athene cunicularia) potentially occur in the Project. While riparian and oak trees occur in the Project, the lack of suitable snags in the onsite trees likely preclude this species from nesting in the Project.
White-tailed Kite
White-tailed kite is not listed pursuant to either the California or federal ESAs; however, the species is fully protected pursuant to Section 3511 of the California Fish and Game Code. This species is a common resident in the Central Valley and the entire length of the California coast, and all areas up to the Sierra Nevada foothills and southeastern deserts (Dunk 1995). In northern California, white-tailed kite nesting occurs from March through early August, with nesting activity peaking from March through June. Nesting occurs in trees within riparian, oak woodland, savannah, and agricultural communities that are near foraging areas such as low elevation grasslands, agricultural, meadows, farmlands, savannahs, and emergent wetlands (Dunk 1995). This species may utilize the onsite trees for nesting.
ECORP Consulting, Inc. August 20, 2019 30 1434 Grove Street Project 2019-040
Biological Resources Assessment for the 1434 Grove Street Project
Western Burrowing Owl
The Western burrowing owl is not listed pursuant to either the California or federal ESAs; however, it is designated as a BCC by the USFWS and an SSC by the CDFW. Burrowing owls inhabit dry open rolling hills, grasslands, desert floors, and open bare ground with gullies and arroyos, but can also inhabit developed areas such as vacant lots and golf courses. This species typically uses burrows created by fossorial mammals, most notably the California ground squirrel (Spermophilus beecheyi) but may also use manmade structures such as pipes and culverts. This species may utilize onsite ruderal and grassland areas. The observed lack of suitable burrows onsite, likely precludes this species from occurring in the Project.
MBTA Protected Birds
Riparian woodland and other trees found in the Project support potential nesting habitat for birds protected under the MBTA. These could include common species such as northern mockingbird and house finch (Haemorhous mexicanus).
4.5.4 Mammals
One special-status mammal species, Pallid bat, was identified as potentially occurring in the Project site. This species is considered to potentially roost in in trees located in the riparian corridor and in other scattered areas of the Project.
Pallid Bat
The pallid bat is not listed pursuant to either the California or federal ESAs; however, this species is considered an SSC by CDFW. The pallid bat is a large, light-colored bat with long, prominent ears and pink, brown, or grey wing and tail membranes. This species ranges throughout North America from the interior of British Columbia, south to Mexico, and east to Texas. The pallid bat inhabits low elevation (below 6,000 feet) rocky arid deserts and canyonlands, shrub-steppe grasslands, karst formations, and higher elevation coniferous forest (above 7,000 feet). This species roosts alone or in groups in the crevices of rocky outcrops and cliffs, caves, mines, trees, and in various human structures such as bridges, and barns. Pallid bats are feeding generalists that glean a variety of arthropod prey from surfaces as well as capturing insects on the wing. Foraging occurs over grasslands, oak savannahs, ponderosa pine forests, talus slopes, gravel roads, lava flows, fruit orchards, and vineyards. Although this species utilizes echolocation to locate prey, often they use only passive acoustic cues. This species is not thought to migrate long distances between summer and winter sites (WBWG 2017). This species may utilize the onsite trees for roosting.
4.6 Wildlife Movement/Corridors
While wildlife use and wildlife movements through the Project is expected to be minimized due to the developed nature of the lands surrounding the Project, Foss Creek, including its perennial flows and adjacent riparian habitat, provide a movement for a variety of species, including several special status species (see Section 4.5).

4.7 Critical Habitat
There is no Critical Habitat designated within the Project (CDFW 2019, USFWS 2019b, NMFS 2019).
5.0 RECOMMENDATIONS
This section summarizes possible measures to avoid, minimize, or compensate for potential impacts to biological resources from the proposed Project, including those to Waters of the U.S., special-status plant and wildlife resources, movement corridors, and oak woodland. Mitigation recommendations are provided, but may be revised based on the CEQA analysis and project permitting.
5.1 Waters of the U.S.
The aquatic resources delineation (ARD) field surveys identified potential Waters of the U.S. within the Project Area. An ARD report has been developed but has not been submitted to the USACE for verification. The current proposed Project has been designed to avoid impacts to the potential Waters of the U.S. identified on-site (Figure 4, Site Plan). If these features are verified as Waters of the U.S. by USACE and if disturbance would occur to Waters of the U.S. within the Project, the following measures would be recommended to minimize potential impacts to Waters of the U.S.:
Authorization to fill wetlands under the Section 404 of the federal CWA (Section 404 Permit) must be obtained from USACE prior to discharging any dredged or fill materials into any Waters of the U.S. Mitigation measures will be developed as part of the Section 404 Permit to ensure no net loss of wetland function and values. To facilitate such authorization, an application for a Section 404 Permit for the Project will be prepared and submitted to USACE, and will include direct, avoided, and preserved acreages to Waters of the U.S. Mitigation for impacts to Waters of the U.S. typically consists of a minimum of a 1:1 ratio for direct impacts; however final mitigation requirements will be developed in consultation with USACE.
A Water Quality Certification or waiver pursuant to Section 401 of the CWA must be obtained for Section 404 permit actions.
5.2 Special-Status Plants
Following completion of the initial site visit, the Project Area was found to provide potential habitat for nine special-status plants (Section 4.5). These include Sonoma sunrise, bristly sedge, Pappose tarplant, dwarf downingia, congested-headed hayfield tarplant, Burke’s goldfield, Sebastopol meadowfoam, Baker’s navarretia, and marsh checkerbloom. No special-status plants, however, were found during the focused protocol-level special status early and late season plant surveys and none are considered to occur on-site. No further measures pertaining to special-status plants are recommended.

5.3 Special-Status Invertebrate
Suitable habitat for one special-status invertebrate species, California freshwater shrimp, occurs in the Project site in association with Foss Creek. The Project is currently proposing to avoid Foss Creek. The following measure is recommended to minimize potential impacts to California freshwater shrimp:
If impacts to Foss Creek are avoided, no further measures are recommended. However, if impacts to Foss Creek will occur for the Project, surveys and/or consultation with USFWS and CDFW will be required for potential impacts to California freshwater shrimp.
5.4 Special-Status Fish
Foss Creek provides suitable habitat for four special-status fish species: hardhead, Central California Coast Coho salmon, California Coastal Chinook salmon, and Central California Coast steelhead, which have a potential to occur in Foss Creek at the Project site. The Project is currently proposing to avoid impacting Foss Creek and riparian vegetation along the stream bank within the Project boundary. The following measures are recommended to minimize potential impacts to special-status fish potentially occurring in Foss Creek:
Conduct vegetation removal during the dry season construction window (e.g., June through October) to minimize the potential adverse effects on sensitive early life stages of special-status fish.
Implement Best Management Practices to minimize potential erosion entering Foss Creek.
If impacts to Foss Creek are avoided, no further measures are recommended. However, if impacts to Foss Creek will occur for the Project, consultation with NMFS will be required for potential impacts to ESA-listed CCC Coho salmon, CC Chinook salmon, and CCC steelhead; consultation with CDFW will be required for potential impacts to California ESA-listed CCC Coho salmon.
5.5 Special-Status Amphibians
Suitable habitat for three special-status amphibian species, California giant salamander, California red- legged frog, and foothill yellow-legged frog, occur in the Project site in association with Foss Creek. The Project is currently proposing to avoid Foss Creek. The following measures are recommended to minimize potential impacts to California giant salamander, California red-legged frog, and foothill yellow-legged frog:
Conduct a pre-construction clearance survey for California giant salamander, California red- legged frog, and foothill yellow-legged frog within 48 hours of the start of construction. If California red-legged frog are observed, consultation with USFWS will be required. If California giant salamander and/or Foothill yellow-legged frog are observed, consultation with CDFW will be required.
If impacts to Foss Creek are avoided, no further measures are recommended. However, if impacts to Foss Creek will occur for the Project, surveys and/or consultation with USFWS and CDFW will

be required for potential impacts to California giant salamander, California red-legged frog, and foothill yellow-legged frog.
5.6 Special-Status Reptiles
Suitable aquatic habitat and marginally suitable upland habitat for one special-status reptile species, northern western pond turtle, is present within the Project site. The following measures are recommended to minimize potential impacts to the northern western pond turtle:
Conduct a preconstruction clearance survey for northern western pond turtle within 48 hours of the start of construction. If northern western pond turtles are observed in the construction zone, a qualified biologist shall relocate the turtle to a location away from the construction zone.
5.7 Special-Status Birds and MBTA-Protected Birds (including Raptors)
Suitable nesting habitat for two special-status birds is present within the Project Area (Section 4.5). These include white-tailed kite and western burrowing owl. If special-status nesting birds are present, the proposed Project could result in harassment to nesting individuals and may temporarily disrupt foraging activities.
In addition to white-tailed kite and western burrowing owl, all native birds, including raptors, are protected under the federal MBTA. As such, to ensure that there would be no impacts to protected active nests, the following measures would be recommended if construction were to take place during the nesting bird season:
Conduct a pre-construction nesting bird survey of all suitable habitats in the Project Area within 14 days prior to the commencement of construction during the nesting season (February 1 – August 31). Conduct a pre-construction nesting raptor survey within 500 feet of the Project Area and conduct a pre-construction nesting passerine survey within 100 feet of the Project Area. These surveys may be conducted concurrently. Pre-construction nesting surveys are not recommended for construction activities that begin outside of the nesting season.
If active nests are found, a no-disturbance buffer around the nests shall be established. The buffer distance shall be established by a qualified biologist in consultation with CDFW and/or USFWS based upon the species. The buffer shall be maintained until the fledglings are capable of flight and become independent of the nest tree (which is to be determined by a qualified biologist). Once the young are independent of the nest, no further measures are recommended.
5.8 Special-Status Mammals
There is one special-status mammal, pallid bat, that could potentially occur within the Project Area (Section 4.5). To ensure that this species is not impacted, the following measures are recommended:
Conduct pre-construction roosting bat surveys for all suitable roosting habitat (i.e., trees and manmade structures) prior to construction activities. If suitable roosting habitat is identified, a qualified biologist will conduct an evening bat emergence survey that may include acoustic monitoring to determine whether or not bats are present. If pallid bats are found, consultation
ECORP Consulting, Inc. August 20, 2019 35 1434 Grove Street Project 2019-040
Biological Resources Assessment for the 1434 Grove Street Project
with CDFW prior to initiation of disturbance of suitable roosting habitat will be required. If bats are not found during the preconstruction surveys, no further measures will be necessary.
5.9 Tree/Riparian Impacts
Tree protection procedures are identified in the Project’s Arborist report (MacNair and Associates 2019) and include tree protection and riparian fencing, trunk protection, and soil protection. Additional mitigation recommendations provided in the Arborist report include plantings, improvement of the site through removal of exotic, invasive plant species, and general woodland cleanup. No riparian trees will be removed.

In Reply Refer To: March 18, 2019 Consultation Code: 08ESMF00-2019-SLI-1402 Event Code: 08ESMF00-2019-E-04507 Project Name: Industrial Project Healdsburg, CA
Subject: List of threatened and endangered species that may occur in your proposed project location, and/or may be affected by your proposed project
To Whom It May Concern:
The enclosed species list identifies threatened, endangered, proposed and candidate species, as well as proposed and final designated critical habitat, under the jurisdiction of the U.S. Fish and Wildlife Service (Service) that may occur within the boundary of your proposed project and/or may be affected by your proposed project. The species list fulfills the requirements of the Service under section 7(c) of the Endangered Species Act (Act) of 1973, as amended (16 U.S.C. 1531 et seq.).
Please follow the link below to see if your proposed project has the potential to affect other species or their habitats under the jurisdiction of the National Marine Fisheries Service: http://www.nwr.noaa.gov/protected_species/species_list/species_lists.html
New information based on updated surveys, changes in the abundance and distribution of species, changed habitat conditions, or other factors could change this list. Please feel free to contact us if you need more current information or assistance regarding the potential impacts to federally proposed, listed, and candidate species and federally designated and proposed critical habitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the Act, the accuracy of this species list should be verified after 90 days. This verification can be completed formally or informally as desired. The Service recommends that verification be completed by visiting the ECOS-IPaC website at regular intervals during project planning and implementation for updates to species lists and information. An updated list may be requested through the ECOS-IPaC system by completing the same process used to receive the enclosed list. 03/18/2019 Event Code: 08ESMF00-2019-E-04507 2
The purpose of the Act is to provide a means whereby threatened and endangered species and the ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2) of the Act and its implementing regulations (50 CFR 402 et seq.), Federal agencies are required to utilize their authorities to carry out programs for the conservation of threatened and endangered species and to determine whether projects may affect threatened and endangered species and/or designated critical habitat.
A Biological Assessment is required for construction projects (or other undertakings having similar physical impacts) that are major Federal actions significantly affecting the quality of the human environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2) (c)). For projects other than major construction activities, the Service suggests that a biological evaluation similar to a Biological Assessment be prepared to determine whether the project may affect listed or proposed species and/or designated or proposed critical habitat. Recommended contents of a Biological Assessment are described at 50 CFR 402.12.
If a Federal agency determines, based on the Biological Assessment or biological evaluation, that listed species and/or designated critical habitat may be affected by the proposed project, the agency is required to consult with the Service pursuant to 50 CFR 402. In addition, the Service recommends that candidate species, proposed species and proposed critical habitat be addressed within the consultation. More information on the regulations and procedures for section 7 consultation, including the role of permit or license applicants, can be found in the "Endangered Species Consultation Handbook" at: http://www.fws.gov/endangered/esa-library/pdf/TOC-GLOS.PDF
Please be aware that bald and golden eagles are protected under the Bald and Golden Eagle Protection Act (16 U.S.C. 668 et seq.), and projects affecting these species may require development of an eagle conservation plan (http://www.fws.gov/windenergy/ eagle_guidance.html). Additionally, wind energy projects should follow the wind energy guidelines (http://www.fws.gov/windenergy/) for minimizing impacts to migratory birds and bats.
Guidance for minimizing impacts to migratory birds for projects including communications towers (e.g., cellular, digital television, radio, and emergency broadcast) can be found at: http:// www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/towers.htm; http:// www.towerkill.com; and http://www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/ comtow.html.
We appreciate your concern for threatened and endangered species. The Service encourages Federal agencies to include conservation of threatened and endangered species into their project planning to further the purposes of the Act. Please include the Consultation Tracking Number in the header of this letter with any request for consultation or correspondence about your project that you submit to our office.

Endangered Species Act Species There is a total of 6 threatened, endangered, or candidate species on this species list.
Species on this list should be considered in an effects analysis for your project and could include species that exist in another geographic area. For example, certain fish may appear on the species list because a project could affect downstream species.
IPaC does not display listed species or critical habitats under the sole jurisdiction of NOAA Fisheries1, as USFWS does not have the authority to speak on behalf of NOAA and the Department of Commerce.
See the "Critical habitats" section below for those critical habitats that lie wholly or partially within your project area under this office's jurisdiction. Please contact the designated FWS office if you have questions.
