Agenda — Cloverdale City Council, February 9, 2022 (part 2 of 4)

October 2021
A. INTRODUCTION AND SUMMARY
In May 2009, the City of Cloverdale adopted the City of Cloverdale General Plan,1 as well as an associated Environmental Impact Report (EIR) for the updated General Plan.2 The General Plan
EIR is a program EIR, prepared pursuant to Section 15168 of the CEQA Guidelines (Title 14, California Code of Regulations [CCR], Sections 15000 et seq.). The General Plan EIR analyzed full implementation of the General Plan and identified measures to mitigate the significant adverse impacts associated with the General Plan.

Section 21084 of the Public Resources Code (PRC) requires the CEQA Guidelines to include a list of classes of projects which have been determined not to have a significant effect on the environment and which shall, therefore, be exempt from the provisions of CEQA. In response to that mandate, the Secretary of the Natural Resources Agency has found that several classes of projects listed in Article 19 of the CEQA Guidelines do not have a significant effect on the environment and, thus, are declared to be categorically exempt from the requirement for the preparation of environmental documents.

The purpose of this Memorandum is to evaluate the Cloverdale Alexander Valley Apartments Project (proposed project) to determine whether the proposed project is exempt from review under the California Environmental Quality Act (CEQA). As will be demonstrated below, the proposed project can be considered exempt from CEQA, consistent with CEQA Guidelines Section 15332, In-Fill Development Projects. In addition, none of the exceptions to categorical exemptions specified by CEQA Guidelines Section 15300.2 are applicable to the proposed project.

B. PROJECT DESCRIPTION
The following provides a description of the project site’s current location and setting, as well as the proposed project components and the discretionary actions required for the project.

Project Location and Setting
The project site consists of a 3.43-acre parcel located at 401 Asti Road in the City of Cloverdale, California (see Figure 1 and Figure 2). The majority of the site (3.33 acres) is identified by Assessor’s Parcel Number (APN) 001-211-018 and is designated Transit Oriented Development (TOD) by the City’s General Plan and zoning code, while the remaining 0.10-acre of the site is identified by APN 001-211-019, and is designated Low Density Residential (LDR) by the City’s General Plan and zoning code. The 0.10-acre portion of the site is not part of the proposed residential building development area.

Currently, the project site is undeveloped and consists primarily of annual grassland with a small area of riparian wetland vegetation along the southern boundary and a seasonal wetland/roadside ditch habitat along the western boundary. The site is bounded by Asti Road to the west, followed by Union Pacific Railroad (UPRR) tracks, Highway 101, and single-family residences; Railroad Avenue to the south, followed by a lumber yard; and vacant land with scattered single-family residences to the north and east.

Project Components
The proposed project would include the development of 75 affordable residential units distributed between three, three-story buildings (Building A, Building B, and Building C) (see Figure 3). 1 City of Cloverdale.

A 2,515-square foot (sf) community area would also be developed as part of Building C. Other improvements would include the development of on-site recreational facilities, surface-level parking, and four bioretention areas, as well as off-site improvements along Asti Road at the project frontage.

Building A would consist of 38 units, including 16 one-bedroom units, 12 two-bedroom units, and 10 three-bedroom units. Building B would consist of 20 units, including 10 one-bedroom units, six two-bedroom units, and four three-bedroom units. Building C would consist of 17 units, including six one-bedroom units, six two-bedroom units, and five three-bedroom units. The units would include living areas, kitchens, bathroom areas, and private patios/balconies. One hundred percent of the proposed project’s residential units would be affordable for families with incomes between 30 to 60 percent of the average median income (AMI). The proposed buildings would each consist of three stories, with a maximum height of 40 feet, and the combined square footage of all on-site buildings would be approximately 61,033 sf.

As mentioned above, Building C would include a 2,515-sf community area which would be accessible to all residents. The community area would consist of a community room, kitchen, maintenance room, fitness room, and laundry room. The community area would also include storge and utility closets, a manager’s office, a maintenance room, and public restrooms.

Access to the site would be provided by two driveways along Asti Road in the northwestern and southwestern portions of the project site. The project would include roadway frontage improvements to Asti Road including the development of sidewalks and the undergrounding of utilities. The proposed project would include 99 surface parking spaces located primarily along the southern and eastern boundaries of the project site. In addition, a bike rack and two bike storage lockers would provide 40 bicycle parking spaces on-site.

The proposed project would include approximately 45,624 sf of landscaping and open space areas. In addition, a tot lot would be developed between Building B and Building C, and a pergola seating and barbeque picnic area, community garden, bocce ball court, and fenced dog park would all be located along the western boundary of the project site.

Four bioretention areas would be included within the project site located in the northern corner of the site, above the northwestern site access, in the southwestern corner of the site, above and below the southwestern site access, and in the southeast corner of the site. All infrastructure required to provide utilities such as water and sewer would be developed by a connection to the existing mains in the project vicinity.

Requested/Required Entitlements
The proposed project would require Major Design Review and Plot Plan Review approvals by the City. In addition, the proposed project is seeking a 35 percent density bonus.

C. DISCUSSION
The following section contains substantial evidence showing that the proposed project can be considered exempt from CEQA and is not subject to any of the exceptions set forth in Section 15300.2 of the CEQA Guidelines. As demonstrated in the analysis below, the proposed project qualifies for exemption under CEQA Guidelines Section 15332, Class 32. 162

In-Fill Development Project Exemption
Article 19 of the CEQA Guidelines, Sections 15300 through 15333, includes a list of classes of projects that have been determined to not have a significant effect on the environment, and are therefore exempt from CEQA. Section 15332 of the CEQA Guidelines provides a categorical exemption for infill development projects that meet the following criteria:
(a) The project is consistent with the applicable general plan designation and all applicable general plan polices as well as with applicable zoning designation and regulations. (b) The proposed development occurs within the city limits on a project site of no more than five acres substantially surrounded by urban uses. (c) The project site has no value as habitat for endangered, rare or threatened species. (d) Approval of the project would not result in any significant effects relating to traffic, noise, air quality, or water quality.
(e) The site can be adequately served by all required utilities and public services.

The applicability of the above criteria to the proposed project is described in the following sections.

Criterion 15332(a): General Plan and Zoning Consistency The City’s General Plan and zoning code designate the site where the buildings would be located as TOD. The TOD designation is intended to provide high-density residential and employment destination uses that directly contribute riders for the Sonoma-Marin Area Rail Transit (SMART) passenger rail station by wholly or partially substituting transit use for automobile use. The TOD land use designation is intended for high-density residential, parkland, or limited commercial and retail uses with a maximum floor-to-area ratio (FAR) of 3.0, a maximum building height of 40 feet, and a maximum density of 20.0 per acre. The proposed multi-family residential use would be consistent with the types of uses anticipated for the project site per the City’s General Plan and zoning code. The TOD zone allows for a base density of 66 units on the project site (3.33 acres x 20 units per acre) and provides that “[d]ensities may be increased as provided for under State Density Bonus Law [California Government Code [CGC] Sections 65915 through 65918]…” (Cloverdale Municipal Code, Table 18.05.040-A, fn. 5.) As “[o]ne hundred percent of all units in the development, including total units and density bonus units, but exclusive of a manager’s unit or units, are for lower income households[,]” the State Density Bonus Law allows for up to an 80 percent density bonus for the proposed project, which would allow for up to 119 units on the project site. However, the proposed project would require approval of only a 13 percent density bonus to allow for the proposed 75 dwelling units to be developed on-site. In addition, the project would result in a FAR of 0.4, which is compatible with the City’s maximum FAR for the TOD designation, and the proposed buildings would have a maximum height of 40 feet, which complies with the City’s building height limit for the designation.

Furthermore, the proposed project would comply with applicable General Plan policies and zoning regulations adopted for the purpose of avoiding and/or mitigating adverse environmental effects.

For example, the proposed project would adhere to all of the standards in Section 18.17.070 (Tree Removal Permit Required) of the Cloverdale Municipal Code, which requires the approval of a tree removal permit before the removal of any protected trees, as defined in Section 18.17.050 of the Municipal Code. In addition, the General Plan includes noise-related policies with which the project is consistent, as discussed in the below section addressing 15332(d).

Based on the above, the proposed project meets Criterion 15332(a). 163

October 2021
Criterion 15332(b): Project Location, Size, and Context The project site consists of a 3.43-acre parcel located within the Cloverdale city limits. The site is located near existing urban development including multiple roadways, UPRR tracks, single-family residences and a lumber yard. Thus, the proposed project meets Criterion 15332(b).

Criterion 15332(c): Endangered, Rare, or Threatened Species Given the undeveloped nature of the project site, a Biological Resources Assessment (BRA)3 was conducted to assess the potential for occurrence of special-status plant and animal species or their habitats and sensitive habitats such as wetlands, riparian communities, and sensitive natural communities within the site (see Appendix B).

As part of the BRA analysis, a literature review of multiple state and federal databases was conducted to determine the special-status species that have been documented within the project vicinity. In addition, a field assessment to identify any special-status species occurring or potentially occurring on-site was conducted on March 4, 2021; an aquatic resources delineation was conducted for the project site on April 22, 2021; and two special-status plant surveys were conducted for the project site on April 22, 2021 and June 17, 2021.

The aquatic resources delineation indicated that a total of 0.180-acre of aquatic resources exist within the project area, including 0.020-acre of seasonal wetland swale and 0.160-acre of seasonal creek (see ). Additionally, while the majority of the project site consists of wild oats and annual brome grasslands, a total of 0.45-acre of Fremont cottonwood forest and woodland habitat exist along the southern and southwestern borders of the site. According to the BRA, development of the proposed project would result in the permanent removal of approximately 0.125-acre of riparian woodland. However, impacts to riparian woodland would be limited to small infringements into the western and northern extents of the riparian woodland that occurs along the boundary of the project site, and impacts to the seasonal wetland swale or seasonal creek would not occur as a result of the proposed project. Additionally, the proposed project would be designed to minimize impacts to riparian woodland to the extent practicable; and a large portion of the existing riparian woodland surrounding the seasonal creek would be avoided by the proposed project.

Based on species occurrence information from the literature review and field observations, the BRA concluded that special-status plant species do not occur on-site. However, three specialstatus bat species, the pallid bat, the Townsend’s big-eared bat, and the western red bat, which are all listed as Species of Special Concern by the California Department of Fish and Wildlife (CDFW), have the potential to occur on site. Additionally, five special-status bird species, including the Allen’s Hummingbird, (listed as a Bird of Conservation Concern by the USFWS; the Cooper’s hawk, listed as a CDFW Watch List species; and the Nuttall’s woodpecker, oak titmouse, and wrentit, all listed as Birds of Conservation Concern by the USFWS, have the potential to occur on-site.

This section of the exemption criteria focuses narrowly on whether the project site has value as habitat for endangered, rare or threatened species. Thus, the relevant inquiry is not whether any special-status species could occur on-site due to the habitat types present, but more specifically, whether on-site habitats provide value to endangered, rare, or threatened species. None of the aforementioned bat or bird species are listed pursuant to the California Endangered Species Act or the federal Endangered Species Act. Therefore, while the permanent removal of approximately

0.125-acre of riparian woodland would occur as a result of the project, this would not conflict with 3 ECORP Consulting Group, Inc. Biological Resources Assessment for the Alexander Valley Cloverdale Housing Project. October 15, 2021.

15332(c) because the habitat does not support endangered, rare, or threatened species.

Therefore, impacts to endangered, rare, or threatened wildlife or plant species would not occur as a result of the proposed project; and the project would meet Criterion 15332(c).

Criterion 15332(d): Traffic, Noise, Air Quality, and Water Quality The following sections present analysis regarding potential effects related to traffic, noise, air quality, and water quality resulting from implementation of the proposed project.

Traffic
The law has changed with respect to how transportation-related impacts may be addressed under CEQA. Traditionally, lead agencies used level of service (LOS) to assess the significance of such impacts, with greater levels of congestion considered to be more significant than lesser levels. In 2013, however, the Legislature passed Senate Bill (SB) 743 with the intention of ultimately doing away with LOS in most instances as a basis for environmental analysis under CEQA. As result of SB 743, local jurisdictions may no longer rely on vehicle LOS and similar measures related to delay as the basis for determining the significance of transportation impacts under CEQA.

Pursuant to SB 743, the Natural Resources Agency promulgated CEQA Guidelines Section 15064.3 in late 2018, and it became effective in early 2019. Section 15064.3 of the CEQA Guidelines provides specific considerations for evaluating a project’s transportation impacts.

Pursuant to Section 15064.3, analysis of vehicle miles travelled (VMT) attributable to a project is the most appropriate measure of transportation impacts. Other relevant considerations may include the effects of the project on transit and non-motorized travel. As discussed in a Focused Transportation Analysis prepared for the proposed project by TJKM Transportation Consultants, the project would generate an average of 593 daily trips, including 38 AM Peak Hour Trips, and 46 PM Peak Hour Trips (see Appendix C).4
However, the California Governor’s Office of Planning
and Research (OPR) released The Technical Advisory on Evaluating Transportation Impacts in CEQA, which includes screening thresholds to identify when a lead agency may screen out VMT impacts. The OPR recommendations include the screening thresholds criteria listed below:
• OPR recommends that office or residential projects not exceeding a level of 15 percent below existing VMT per capita may indicate a less-than-significant impact on VMT; • OPR recommends that projects (including office, residential, retail, and mixed-use developments) proposed within half a mile of an existing major transit stop or within a quarter of an existing stop along a high-quality transit corridor may be presumed to have a less-than-significant impact;
• OPR recommends that 100 percent of affordable residential development in infill locations be presumed to have a less-than-significant impact on VMT; and • OPR recommends that projects that generate or attract fewer than 110 trips per day generally may be assumed to cause a less-than-significant impact.

Because the proposed project would be a 100 percent affordable residential development, pursuant to the above OPR recommendations, the proposed project would be presumed to have a less-than-significant impact related to VMT. The OPR guidelines state that adding affordable housing to infill locations generally improves jobs to housing match, in turn shortening commutes and reducing VMT. In addition, the OPR guidelines state that in areas where existing jobs-housing match is closer to optimal, low-income housing generates less VMT than market-rate housing.

Furthermore, the project site is designated as TOD, which is intended to provide development 4 TJKM. Focused Transportation Analysis for Cloverdale Alexander Valley Apartments. April 16, 2021. 165

that directly contributes riders for the SMART passenger rail station. The nearest transit stop is located less than 0.5-mile away from the project site at the corner of S. East Street and Lake Street. The proposed project would also include the development of sidewalks along Asti Road, and 40 bicycle parking spaces would be provided on-site, which would further promote the use of alternative modes of transportation. Therefore, the proposed project is not anticipated to result in VMT that would be considered to have the potential to result in significant effects on the environment.

Noise
Some land uses are considered more sensitive to noise than others, and, thus, are referred to as sensitive noise receptors. Land uses often associated with sensitive noise receptors generally include residences, schools, libraries, hospitals, and passive recreational areas. Noise sensitive land uses are typically given special attention in order to achieve protection from excessive noise.

The nearest sensitive receptors to the project site are the scattered single-family residences located to the north and east of the project site, with the nearest residence located approximately 115 feet east of the project site.

During operation, the primary sources of noise associated with the proposed project would be limited to residential noise and vehicle traffic noise generated on local roadways. Typical residential noise generated by the proposed project would be relatively minimal and compatible with the adjacent existing single-family residential uses. Given the nearest sensitive receptor is located approximately 115 feet from the project site, the proposed project is not anticipated to contribute a measurable operational noise level increase to the existing ambient noise environment at any sensitive receptor locations. Additionally, given that the project is consistent with the site’s existing land use and zoning designations, traffic noise level increases associated with a multi-family residential development on the project site have been previously anticipated by the City. As such, the project would not result in traffic noise level increases beyond what has been analyzed in the General Plan EIR. Therefore, the proposed project is not anticipated to result in operational noise increases that would be considered to have the potential to result in significant effects on sensitive receptors in the project vicinity.

During the construction of the proposed project, heavy equipment would be used for grading, excavation, paving, and building construction, which could result in temporary noise level increases at nearby sensitive receptors. Noise levels would vary depending on the type of equipment used, how the equipment is operated, and how well the equipment is maintained. In addition, noise exposure at any single point outside the project site would vary depending on the proximity of construction activities to that point. Standard construction equipment, such as backhoes, loaders, and trucks, would be used on-site.

Table 1 shows maximum noise levels associated with typical construction equipment. Based on the table, activities involved in typical construction would generate maximum noise levels up to 85 dB at a distance of 50 feet.

As one increases the distance between equipment, or increases separation of areas with simultaneous construction activity, dispersion and distance attenuation reduce the effects of combining separate noise sources. The noise levels from a source decrease at a rate of approximately 6 dB per every doubling of distance from the noise source. According to General Plan Implementation Program NE 1-2.a., all new development or construction projects within the City that create exterior noise impacts in excess of levels shown in Exhibit 4.1 of the General Plan are required to provide mitigation at the affected property line to meet the exterior noise standards.

Pursuant to Exhibit 4.1 of the General Plan, Community Noise Exposure at residential land uses must be between 55 and 60 Ldn/CNEL dB to meet the normally acceptable noise level standards of the City.

Using the maximum construction noise levels (Lmax) provided in Table 1, the distance of the nearest sensitive receptor from the project site (approximately 115 feet), and limitation of construction activities to daytime hours, construction noise for the proposed project was calculated to be between 55 and 60 dBA Ldn at the nearest sensitive receptor.5 Therefore, the
proposed project would not result in exterior noise impacts in excess of levels shown in Exhibit

4.1 of the General Plan.

Based on the above, approval of the proposed project would not result in any significant effects related to noise exposure during project construction or operation.

Air Quality and Greenhouse Gas Emissions
The project site is within the North Coast Air Basin (NCAB), which is under the jurisdiction of the Northern Sonoma County Air Pollution Control District (NSCAPCD). The NCAB is in attainment or unclassified (meaning there is insufficient data to determine attainment) for all California Ambient Air Quality Standards (CAAQS). As a result, numerical thresholds of significance for air pollutants have not been established by the NSCAPCD for CEQA analysis purposes, as such thresholds of significance are typically developed based on attainment goals set forth within an air quality plan.

Based on the recommendation of the NSCAPCD,6
this analysis applies the thresholds of
significance used for CEQA analyses within the nearby San Francisco Bay Area Air Basin (SFBAAB), formulated by the Bay Area Air Quality Management District (BAAQMD). The BAAQMD thresholds of significance are based on the SFBAAB’s current nonattainment status of 5 Saxelby Acoustics. Construction Noise Operation.

ozone and PM emissions and the subsequent air quality attainment plans. Because the NCAB is in attainment or unclassified for all AAQS, using the BAAQMD thresholds of significance for the proposed project analysis would allow for a conservative analysis. The BAAQMD’s thresholds of significance are listed in Table 2. If a project were to exceed the BAAQMD’s criteria pollutant emission thresholds during construction or operations, the project could be considered to result in an adverse air quality impact.

Additionally, based on the recommendation of the NSCAPCD, the City has elected to use the BAAQMD’s thresholds of significance for GHG emissions. The GHG emissions threshold of significance used in this analysis is whether the proposed project would result in operational GHG emissions in excess of the following:
• 1,100 MTCO2e/yr; or
• 4.6 MTCO2e/SP/yr, where “SP” equates to service population, which is the total residents plus employees.

Approach to Analysis
The proposed project’s construction and operational emissions were quantified using the California Emissions Estimator Model (CalEEMod) software version 2020.4.0 - a Statewide model designed to provide a uniform platform for government agencies, land use planners, and environmental professionals to quantify air quality emissions, including greenhouse gas (GHG) emissions, from land use projects. The model applies inherent default values for various land uses, including construction data, vehicle mix, trip length, average speed, etc. Where projectspecific information is available, such information is applied in the model. The proposed project’s modeling assumed the following:
x Construction would occur over approximately 14 months; x Approximately 1,200 cubic yards of soil would be exported during site prep and grading; approximately 4,950 cubic yards of soil would be imported during grading; x The proposed units would not include hearths;
x The project would increase transit accessibility and include on- and off-site pedestrian and bicycle facility improvements;
x The project would include a 20 percent indoor and 25 percent outdoor water reduction; x One hundred percent of the project’s energy demands would be generated on-site; and x The project would have a trip generation rate of 7.9 daily trips per unit.

The proposed project’s estimated emissions associated with construction and operations are provided below. All CalEEMod results are included as Appendix A to this Memorandum. 168

Construction Emissions (Criteria Pollutants)
According to the CalEEMod results, the proposed project would result in maximum construction criteria air pollutant emissions as shown in Table 3. The proposed project’s construction emissions would be below the applicable thresholds of significance. In addition, the proposed project would be subject to all applicable NSCAPCD rules and regulations, such as the implementation of a dust management plan and watering during construction, which would further reduce construction emissions.

Greenhouse Gas Emissions
Emissions of greenhouse gases (GHGs) contributing to global climate change are attributable in large part to human activities associated with the industrial/manufacturing, utility, transportation, residential, and agricultural sectors. Therefore, the cumulative global emissions of GHGs contributing to global climate change can be attributed to every nation, region, and city, and virtually every individual on earth. An individual project’s GHG emissions are at a micro-scale level relative to global emissions and effects to global climate change; however, an individual project could result in a cumulatively considerable incremental contribution to a significant cumulative macro-scale impact.

Implementation of the proposed project would cumulatively contribute to increases of GHG emissions. Estimated GHG emissions attributable to future development would be primarily associated with increases of carbon dioxide (CO2) and, to a lesser extent, other GHG pollutants, such as methane (CH4) and nitrous oxide (N2O) associated with area sources, mobile sources or 169

vehicles, utilities (electricity and natural gas), water usage, wastewater generation, and the generation of solid waste. The primary source of GHG emissions for the project would be mobile source emissions. The common unit of measurement for GHG is expressed in terms of annual metric tons of CO2 equivalents (MTCO2e/yr).

Construction GHG emissions are a one-time release and are, therefore, not typically expected to generate a significant contribution to global climate change. Neither the City nor BAAQMD has an adopted threshold of significance for construction-related GHG emissions and does not require quantification. Nonetheless, the proposed project’s construction GHG emissions have been estimated for disclosure purposes. The CalEEMod emissions estimates prepared for the proposed project determined that unmitigated project construction would result in total emissions of 505.55 MTCO2e over the course of the construction period for the proposed project.

The estimated maximum annual GHG emissions related to operations of the proposed project are presented in Table 5 below. As shown in Table 5, the project’s maximum annual unmitigated operational GHG emissions were estimated to be approximately 659.53 MTCO2e/yr. Thus, implementation of the proposed project would result in operational emissions below the BAAQMD’s applicable 1,100 MTCO2e/yr threshold of significance for GHG emissions.

Source: CalEEMod, October 2021 (see Appendix A).

Based on the above, the proposed project would not be considered to generate GHG emissions, either directly or indirectly, that may have a significant impact on the environment.

Conclusion
As discussed above, the proposed project is not anticipated to result in short-term constructionrelated or long-term operational emissions of air quality pollutants or GHG emissions that would be considered to have the potential to result in significant effects on the environment.

Water Quality
Water quality degradation is regulated by the federal National Pollutant Discharge Elimination System (NPDES) Program, established by the Clean Water Act, which controls and reduces pollutants to water bodies from point and non-point discharges. In California, the NPDES permitting program is administered by the State Water Resources Control Board (SWRCB) through nine RWQCBs. New development within the City that disturbs one or more acres of land is required to comply with the NPDES General Construction Permit and prepare a Stormwater Pollution Prevention Plan (SWPPP) incorporating best management practices (BMPs) to control sedimentation, erosion, and hazardous materials contamination of runoff during construction. The proposed project would disturb approximately 3.43 acres, and, thus, would be subject to the State NPDES General Permit conditions.

Project construction activities such as grading, excavation, and trenching for site improvements would result in the disturbance of on-site soils. As noted previously, the proposed project would be required to provide treatment of on-site stormwater runoff prior to discharging. The exposed soils have the potential to affect water quality in two ways: 1) suspended soil particles and sediments transported through runoff; or 2) sediments transported as dust that eventually reach local water bodies. Spills or leaks from heavy equipment and machinery, staging areas, or building sites also have the potential to enter runoff. Typical pollutants include, but are not limited to, petroleum and heavy metals from construction equipment and products such as paints, solvents, and cleaning agents, which could contain hazardous constituents. Sediment from erosion of graded or excavated surface materials, leaks or spills from equipment, or inadvertent releases of building products could result in water quality degradation if runoff containing the sediment or contaminants should enter receiving waters in sufficient quantities. Impacts from constructionrelated activities would be short-term and of limited duration.

With regard to potential adverse effects to water quality during operations, the proposed project would increase the amount of impervious surface on the project site. However, the proposed project would be subject to post-construction BMP methods to address pollutant loading in offsite discharges. Stormwater runoff within the project site would be directed to on-site bioretention basins located throughout the site, which would provide for treatment of captured runoff prior to discharging; overflow runoff will be allowed to drain to the street system.

Based on the above, the proposed project would not result in any significant effects related to water quality; thus, the project would meet Criterion 15332(d).

Criterion 15332(a): Utilities and Public Services
Water and sewer service for the proposed development would be provided by the City through new connections to existing infrastructure within the project vicinity. The City of Cloverdale has provided a “will serve” letter indicating that the City has adequate capacity in nearby utilities (water, sewer, drainage) to serve the project.7
As discussed previously, stormwater runoff within
the project site would flow into four new on-site bioretention basins, which would provide for treatment and detention of captured runoff prior to discharging. Given the presence of existing utilities in the immediate project vicinity, the proposed project would not require substantial offsite utility improvements. In addition, given that the proposed project is consistent with the site’s current General Plan land use and zoning designations, increases in demand on existing utilities and public services associated with the project have been previously anticipated in the General Plan and accounted for in local planning efforts. Thus, the site would be adequately served by all required utilities and public services.

Exceptions to Categorical Exemptions analysis
Even if a project is ordinarily exempt under any of the potential categorical exemptions, CEQA Guidelines Section 15300.2 provides specific instances where exceptions to otherwise applicable exemptions apply. Exceptions to a categorical exemption apply in the following circumstances:
(a) Location. Classes 3, 4, 5, 6, and 11 are qualified by consideration of where the project is to be located – a project that is ordinarily insignificant in its impact on the environment may in a particularly sensitive environment be significant. Therefore, these classes are considered to apply all instances, except where the project may impact on an 7 Mark Rincon, P.E., Public Works Director, City of Cloverdale.

environmental resource of hazardous or critical concern where designated, precisely mapped, and officially adopted pursuant to law by federal, state, or local agencies. (b) Cumulative Impact. All exemptions for these classes are inapplicable when the cumulative impact of successive projects of the same type in the same place, over time is significant.
(c) Significant Effect. A categorical exemption shall not be used for an activity where there is a reasonable possibility that the activity will have a significant effect on the environment due to unusual circumstances.
(d) Scenic Highways. A categorical exemption shall not be used for a project which may result in damage to scenic resources, including but not limited to, trees, historic buildings, rock outcroppings, or similar resources, within a highway officially designated as a state scenic highway. This does not apply to improvements which are required as mitigation by an adopted negative declaration or certified EIR. (e) Hazardous Waste Sites. A categorical exemption shall not be used for a project located on a site which is included on any list compiled pursuant to Section 65962.5 of the Government Code.
(f) Historical Resources. A categorical exemption shall not be used for a project which may cause a substantial adverse change in the significance of a historical resource.

The following analysis addresses whether any of the exceptions to the CEQA exemption apply to the proposed project.

Criterion 15300.2(a): Location
CEQA exemptions 3, 4, 5, 6, or 11, are qualified by consideration of where the project is to be located. Given that the proposed project qualifies for exemption under CEQA Guidelines Section 15332, Class 32, an exception to the exemption under CEQA Guidelines Section 15300.2(a) does not apply to the proposed project.

Criterion 15300.2(b): Cumulative Impact
Per CEQA Section 15300.2(b), in applying this exception, the cumulative impact must result from “successive projects of the same type in the same place.” Both the “same type” and “same place” limitations restrict the scope of this exception.8
The project site is located near existing urban
development including multiple roadways, UPRR tracks, single-family residences and a lumber yard. Currently, two properties, located approximately 0.35-mile and 1.8-mile from the project site, are proposed for development within the City of Cloverdale. However, the proposed project is consistent with the project site’s General Plan land use and zoning designations, and, therefore, cumulative impacts associated with buildout of the project site, as well as development of other uses in the project area, have been previously anticipated by the City and analyzed in the General Plan EIR. As discussed above, the project would not require substantial off-site utility upsizing or other related improvements with the potential to result in cumulatively considerable impacts. Thus, the project does not include any unique features that would result in new or more severe cumulative impacts beyond what has been analyzed in the General Plan EIR, and an exception to the exemption under CEQA Guidelines Section 15300.2(b) does not apply to the proposed project.

Criterion 15300.2(c): Significant Effect
In listing a class of projects as exempt, the Secretary has determined that the environmental changes typically associated with projects in that class are not significant effects within the meaning of CEQA, even though an argument might be made that they are potentially significant. 8 Stephen L. Kostka and Michael H. Zischke. Practice Under the California Environmental Quality Act, Second Edition [pg. 5-68]. March 2019 Update.

The plain language of CEQA Guidelines Section 15300.2, subdivision (c), requires that a potentially significant effect must be “due to unusual circumstances” for the exception to apply.

The determination as to whether there are “unusual circumstances” (CEQA Guidelines, Section 15300.2(c)) is reviewed under PRC Section 21168.5’s substantial evidence prong. Whether a particular project presents circumstances that are unusual for projects in an exempt class is an essentially factual inquiry. As to this question, the lead agency serves as “the finder of fact”.

First, the proposed project is consistent with the site’s General Plan land use designation and zoning district. Thus, nothing unusual about the type of development proposed would occur, which has been anticipated for the site in prior City planning efforts. Other urban development is also located in the vicinity. As the courts have noted, local conditions are relevant in determining whether the environmental effects of a proposed project are unusual or typical. However, nothing particularly unusual about the project site’s history exists, as the surrounding area has long been subject to residential uses.

Multiple assessments have been conducted for the project site including a Phase I Environmental Site Assessment (ESA) (see Appendix E),9
a Geotechnical Engineering Study (see Appendix
D),10 and a BRA (see Appendix B).11
The Phase I ESA investigation included research of Sanborn maps, aerial photographs, regulatory records and City directories, as well as a search of government environmental databases, a site inspection on November 2, 2020, a Vapor Encroachment Screen (VES), and a search of groundwater monitoring data as maintained by the SWRCB Geotracker database.

Based on the information obtained during the Phase I ESA investigation, the project site has been essentially vacant land from at least 1941 through the present. The project site is located in a commercial/retail and residential area where information related to environmental assessment, remediation and/or management practices is documented for numerous other properties in the general vicinity of the site. Based on the information obtained during Phase I ESA investigation and the site inspection, subsurface environmental site assessment activity that would indicate potential migration of contamination from other nearby sites towards the project site was not discovered or observed. Additionally, the VES did not identify a Vapor Encroachment Condition (VEC) originating from the project site, or from other nearby sites in the project vicinity.

Furthermore, monitoring data collected from wells located in the project vicinity indicated that the average depth to groundwater is between 4.98 and 9.55 feet below the surface. As discussed in the section for Criterion 15300.2(e) below, the project site is not included on any lists of hazardous waste sites.

In addition, after a search of historical aerial imagery of the project site dating back to 1993, and a site visit, which included two exploratory soil boring samples, the Geotechnical Engineering Study concluded that from a geotechnical standpoint, the site is considered suitable for the proposed construction provided the conclusions and recommendations presented in the report are incorporated into the design and construction of the project. As such, the proposed project would be conditioned by the City to submit all project Improvement Plans to a qualified geotechnical engineer, in coordination with the City Engineer, for review and approval to assess 9 KCE Matrix.

whether all recommendations from the Geotechnical Engineering Study have been properly implemented. The recommendations include, but are not limited to: site clearing and stripping, subgrade preparation, fill compaction, utility trench backfilling, foundation design criteria. In addition, the proposed project would be required to comply with all applicable provisions of the 2019 California Building Standards Code (CBSC).

Based on the above, an exception to the exemption under CEQA Guidelines Section 15300.2(c) does not apply to the proposed project.

Criterion 15300.2(d): Scenic Highway
According to the California Department of Transportation (Caltrans) Scenic Highway Mapping System, officially designated State or County scenic highways do not occur in the project vicinity.12 Thus, an exception to the exemption under CEQA Guidelines Section 15300.2(d) does not apply to the proposed project.

Criterion 15300.2(e): Hazardous Waste Sites
The California Environmental Protection Agency provides a list of data resources that provide information regarding the facilities or sites identified as meeting the “Cortese List” requirements, pursuant to Government Code 65962.5. Per a Phase I ESA prepared for the proposed project by KCE Matrix (see Appendix E), the project site is not located on any list compiled pursuant to Section 65962.5 of the Government Code.13 Thus, an exception to the exemption under CEQA Guidelines Section 15300.2(e) does not apply to the proposed project.

Criterion 15300.2(f): Historical Resources
Currently, the project site is vacant and undeveloped, and consists primarily of annual grassland.

As such, the project site does not include any historic structures.

Based on the above, the proposed project would not result in a substantial adverse change in the significance of a historical resource, and an exception to the exemption under CEQA Guidelines Section 15300.2(f) does not apply to the proposed project.

D. CONCLUSION
This Memorandum demonstrates that the proposed project can be considered exempt from CEQA under Section 15332, and does not meet any of the exceptions to categorical exemptions set forth in Section 15300.2 of the CEQA Guidelines.

1.0 INTRODUCTION
On behalf of The Pacific Companies (TPC), ECORP Consulting, Inc. conducted a Biological Resources Assessment (BRA) for the Alexander Valley Cloverdale Affordable Housing Project (Project) located in Sonoma County. For this BRA, the Environmental Study Limits (Study Area) is 3.43 acres. The purpose of the assessment was to collect information on the biological resources present and evaluate the potential for special-status species and their habitats to occur in the Study Area, assess potential biological impacts related to Project activities to inform the Project’s California Environmental Quality Act (CEQA) and National Environmental Policy Act (NEPA) documentation for biological resources.

1.1 Project Location
The Study Area is located in an unsectioned portion of the Rincon De Musalacon Landgrant (Mount Diablo Base and Meridian) of the “Cloverdale, California” 7.5-minute topographic quadrangle (U.S.

Geological Survey [USGS] 1960, photo inspected 1975) (Figure 1-1) and corresponds to Sonoma County Assessor’s Parcel Number (APN) 001-211-018-000 and APN 001-211-019. The Study Area is located northeast of the Asti Road and Railroad Avenue intersection and east of Highway 1 in Cloverdale. The approximate center of the Study Area is located at NAD83 coordinates 38.804580° latitude and - 123.010836° longitude within the Russian Watershed (Hydrologic Unit Code #18010110; Natural Resources Conservation Service [NRCS] et al. 2016).

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 or their habitats and sensitive habitats such as wetlands, riparian communities, and sensitive natural communities within the Study Area.

This assessment includes information generated from assessment-level site reconnaissance of the Study Area. This BRA does not include determinate presence or absence field surveys for any plant or animal species. This assessment includes an analysis of biological resources anticipated to occur within the Study Area as presently defined. The mitigation recommendations presented in this assessment are provided as possible measures to mitigate for impacts to biological resources; these recommendations are based on the preliminary analysis, a review of existing literature, and the results of site reconnaissance survey.

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 Section 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 plants considered by the California Native Plant Society (CNPS) to be rare, threatened, or endangered in California (California Rare Plant Rank [CRPR] 1 and 2), plants about which more information is needed (i.e., species with a CRPR of 3), or plants of limited distribution – a watch list (i.e., species with a CRPR of 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).

Only species that fall into one of the above-listed groups were considered for this assessment. While other species (i.e., special-status lichens, California Natural Diversity Database [CNDDB] tracked species with no special status) are sometimes found in database searches or within the literature, these species were not included within this analysis.

1.3 Project Description
TPC is proposing the development of the Project, an 81-unit affordable housing apartment development in the city of Cloverdale. TPC is a privately held group of firms that develop multifamily housing and charter school facilities.

The Project site (APN 001-211-018) is located in a commercial and residential area on the eastern side of Asti Road, approximately 300 feet north of the intersection of Asti Road and Railroad Avenue in Cloverdale in Sonoma County. The 3.43-acre Project site can be accessed along the entire western property line from Asti Road and along vacant adjacent properties located north, east, and south of the Project site. The site consists of vacant land with no structures. The ground consists of dirt and grass areas and is not improved. Additionally, a dirt road runs in a northwest-southwest direction in the northern portion of the site. The site is located in a mixed-use area of Cloverdale, and commercial, industrial, and residential land uses are located within the general vicinity of the site.

The Proposed Project is within the Cloverdale city limits and is consistent with the property’s intended use.

The site is designated and zoned Transit Oriented Development, which allows for the proposed multifamily development. The adjacent parcels to the north and east are zoned single-family residential.

The adjacent parcel to the south is vacant and zoned general industrial. U.S. Highway 101 borders to the west of Asti Road. The proposed complex would be in close proximity to services including grocery stores, medical services, schools, parks, and employment opportunities. A tentative site plan for the Project is provided in Attachment A.

2.0 REGULATORY SETTING

2.1 Federal Regulations

2.1.1 National Environmental Policy Act
NEPA was signed into law in 1970. NEPA requires federal agencies to integrate environmental values into their decision-making processes by considering the environmental impacts of their proposed actions and reasonable alternatives to those actions. To meet NEPA requirements, federal agencies prepare detailed environmental assessments and Environmental Impact Statements to assess the potential impacts of federally directed projects on the environment.

2.1.1.1 National Environmental Policy Act Significance Criteria The following criteria are used to determine if a project will result in significant impact under NEPA.

According to the NEPA Regulations adopted by the President’s Council on Environmental Quality (40 Code of Federal Regulations [CFR] 1500-1508), the term significantly is based on the twin criteria of context and intensity (40 CFR 1508.27). Context means the affected environment in which a proposed action would occur; it can be local, regional, national, or all three, depending upon the circumstances.

Intensity means the degree to which the proposed action would involve one or more of the following 10 criteria:

Adverse effects associated with beneficial projects;
Effects on public health or safety;
Unique characteristics of the geographic area (e.g., historic resources, park lands, wetlands, wild and scenic rivers, ecologically critical areas);
Degree of controversy;
Degree of highly uncertain effects or unique or unknown risks; Precedent setting effects;
Cumulative effects;
Adverse effects on scientific, cultural, or historical resources; Adverse effects on endangered or threatened species or designated critical habitat (pursuant to the ESA); and
Violations of federal, state, or local environmental law.

2.1.2 Federal Endangered Species Act
The federal ESA protects plants and animals that are listed as endangered or threatened by the USFWS and the National Marine Fisheries Service (NMFS). Section 9 of the ESA prohibits the taking of listed 284
Biological Resources Assessment
ECORP Consulting, Inc.

2020-228
wildlife, where take is defined as “harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, collect, or attempt to engage in such conduct” (50 CFR 17.3). For plants, this statute governs removing, possessing, maliciously damaging, or destroying any listed plant on federal land and removing, cutting, digging up, damaging, or destroying any listed plant on non-federal land in knowing violation of state law (16 U.S.

Code [USC] 1538). Under Section 7 of the ESA, federal agencies are required to consult with the USFWS if their actions, including permit approvals or 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), the USFWS 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 the ESA provides for issuance of incidental take permits where no other federal actions are necessary provided a habitat conservation plan is developed.

2.1.2.1 Section 7
Section 7 of ESA mandates that all federal agencies consult with USFWS and NMFS to ensure federal agencies’ actions do not jeopardize the continued existence of a listed species or adversely modify critical habitat for listed species. If direct 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 applicant must conduct a biological assessment (BA) for the purpose of analyzing the potential effects of the project on listed species and critical habitat to establish and justify an "effect determination." The federal agency reviews the BA; if it concludes that the project may adversely affect a listed species or its habitat, it prepares a BO, which may recommend "reasonable and prudent alternatives" to the project to avoid jeopardizing or adversely modifying habitat.

2.1.2.2 Critical Habitat
Critical habitat is defined in Section 3 of the 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.

Critical habitat designations identify, to the extent known and using the best scientific data available, habitat areas that provide essential lifecycle needs of the species. 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; 285

3. Cover or shelter;

4. Sites for breeding, reproduction, or rearing (or development) of offspring; and

5. Habitats that are protected from disturbance or are representative of the historic, geographical, and ecological distributions of a species;

2.1.3 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.

2.1.4 Federal 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 U.S. Army Corps of Engineers (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 and may override a USACE permit.

Substantial impacts to wetlands may require an individual permit. Projects that only minimally affect wetlands may meet the conditions of one of the existing Nationwide Permits. A Water Quality Certification or waiver pursuant to Section 401 of the CWA is required for Section 404 permit actions; in California, this certification or waiver is issued by the Regional Water Quality Control Board (RWQCB).

2.2 State or 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 286

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.

2.2.2 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 California ESAs. Fully protected species are identified in the California Fish and Game Code § 4700 for mammals, § 3511 for birds, §5 050 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.

2.2.3 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 California 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 the NPPA. Plants listed as rare under NPPA are not protected under the California ESA but are still protected under the provisions of the NPPA. The Fish and Game Commission no longer lists plants under NPPA, reserving all listings to the California ESA.

2.2.4 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:

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.
287
Biological Resources Assessment
ECORP Consulting, Inc.

Alexander Valley Cloverdale Housing Project
8 October 15, 2021

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.

2.2.5 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 (LSA) 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 LSA Agreement.

2.2.6 Porter-Cologne Water Quality Act
The RWQCB implements water quality regulations under the federal CWA and the state 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 storm water 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 the USACE due to a lack of connectivity with a navigable water body. The RWQCB may require issuance of Waste Discharge Requirements for these activities.

2.2.7 California Environmental Quality Act
In accordance with CEQA Guidelines § 15380, a species or subspecies not specifically protected under the federal or California ESAs or the NPPA may be considered endangered, rare, or threatened for CEQA review purposes if the species meets certain criteria specified in the Guidelines. These criteria parallel the definitions used in the ESA, California ESA, and NPPA. Section 15380 was included in the CEQA 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 the ESA, California ESA, or NPPA, but that may meet the definition of endangered, rare, or threatened. Animal species identified as SSC by CDFW, birds identified as a BCC by USFWS, and plants identified by the CNPS as rare, threatened, or endangered may meet the CEQA definition of rare or endangered.

2.2.7.1 Species of Special Concern
Species of special concern are defined by CDFW as a species, subspecies, or distinct population of an animal native to California that are not legally protected under the federal ESA, California ESA, or California Fish and Game Code, but currently satisfy 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 range; 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
Species of special concern are typically associated with habitats that are threatened.

Projects that result in substantial impacts to SSC may be considered significant under CEQA.

2.2.7.2 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 U.S. The list identifies the migratory and nonmigratory bird species (beyond those already designated as federally threatened or endangered) that represent the USFWS highest conservation priorities. Projects that result in substantial impacts to BCC may be considered significant under CEQA.

2.2.7.3 Sensitive Natural Communities
The CDFW maintains the California Natural Community List (CDFW 2020), which provides a list of vegetation alliances, associations, and special stands as defined in the Manual of California Vegetation (Sawyer et al. 2009), along with their respective state and global rarity ranks. Natural communities with a state rarity rank of S1, S2, or S3 are considered sensitive natural communities. Impacts to sensitive natural communities may be considered significant under CEQA.

2.2.7.4 California Rare Plant Ranks
The CNPS maintains the Inventory of Rare and Endangered Plants of California (CNPS 2021), which provides a list of plant species native to California that are threatened with extinction, have limited 289
Biological Resources Assessment

2020-228
distributions, 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 CNDDB maintained by CDFW. 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; Rare Plant Rank 3 – a review list of plants about which more information is needed; and 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 (more than 80 percent of occurrences threatened/high degree and immediacy of threat);
Threat Rank 0.2 – Moderately threatened in California (20 to 80 percent occurrences threatened/moderate degree and immediacy of threat); and Threat Rank 0.3 – Not very threatened in California (less than 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 2021).

Substantial impacts to plants ranked 1A, 1B, 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.

2.2.7.5 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 (e.g., rare, threatened, or endangered) species are considered significant.

Assessment of impact significance to populations of non-listed species (e.g., SSC) usually considers the 290

2020-228
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 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, which provides examples of impacts that would normally be considered significant.

An evaluation of whether 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 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.

2.2.8 City of Cloverdale Tree Protection Ordinance
Projects shall be designed to minimize the destruction of protected trees. With development permits, a tree preservation plan designating all trees with a trunk diameter of 45 inches or greater and their protected perimeters in areas that will be impacted by the proposed development, such as the building envelopes and access roads will be submitted. Protected tree means black oak (Quercus kelloggii), valley oak (Quercus lobata), blue oak (Quercus douglasii), interior live oak (Quercus wislizenii), coast live oak (Quercus agrifolia), oracle oak (Quercus morehus), Oregon oak (Quercus garryana), American sycamore (Planatus occidentalis), California bay (Umbellularia californica), California or coast redwood (Sequoia sempervirens), Douglas fir (Pseudotsuga Menziesii), Ponderosa pine (Pinus ponderosa), black walnut (Juglans nigra), English walnut (Juglans regia), and their hybrids. In addition, heritage trees, all trees located in a riparian corridor, any tree required to be planted or preserved as environmental mitigation or condition of approval for a discretionary development application or other development permit, and trees in the public right-of-way are protected.

2.2.9 City of Cloverdale General Plan
The purpose of the Conservation, Design, and Open Space Element of the City of Cloverdale General Plan is to is to maintain and encourage development that complements the natural visual setting of Cloverdale—a small town on the valley floor with hills to the west, north, and south and the Russian River to the east, separated from the other urbanized areas of Sonoma County by natural features and agricultural areas (City of Cloverdale 2010). The following goals of the Conservation, Design, and Open Space Element are pertinent to this Project:

CDO 3: Maintain and improve the design of the built environment. Improve the appearance of entries and approaches to the downtown and the community. Provide design guidelines for new development and growth.

3.2 Field Surveys Conducted

3.2.1 Reconnaissance Field Assessment
This BRA includes an initial site visit to generally characterize onsite resources including plant communities, wildlife, special-status species, and sensitive natural communities. A preliminary aquatic resources (i.e., potential Waters of the U.S./State) assessment was conducted during this site visit.

A field assessment for special-status species was conducted by ECORP biologist Keith Kwan on March 4, 2021. The purpose of this assessment was to identify potential biological resources constraints (e.g., aquatic resources, special-status species) onsite, identify regulatory requirements for development of the site, and assess potential mitigation needs. During the assessment, the following biological resource information was collected:

Direct observations of special-status species;
Animal and plant species directly observed;
Habitat and vegetation communities; and
Identification of aquatic resources.

3.2.2 Aquatic Resources Delineation
An aquatic resources delineation was conducted for the Project site on April 22, 2021. The aquatic resources delineation report is provided in Attachment C.

3.2.3 Special-Status Plant Survey
A special-status plant survey was conducted for the Study Area by ECORP Biologist Hannah Stone on April 22 and June 17, 2021. The survey was conducted in accordance with guidelines promulgated by the USFWS (USFWS 2000), CDFW (CDFW 2018), and CNPS (CNPS 2001). No special-status plant species were observed within the Study Area during the survey. Results of the survey have been incorporated into this BRA. A list of all plant species observed onsite during the survey is included in Attachment D.

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 species considered to have the potential to occur within the Study Area was generated (Table 4-1; Section 4.6). Each of the species that were considered as potentially occurring within the Study Area or vicinity was evaluated based on the following criteria:

Present - Species was observed during field surveys or is known to occur within the Study Area 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 Study Area.

Low Potential to Occur - Marginal or limited amounts of habitat occur, or the species is not known to occur within the vicinity of the Study Area based on CNDDB records and other available documentation.

Absent - No suitable habitat (including soils and elevation requirements), or the species is not known to occur within the Study Area or the vicinity of the Study Area based on CNDDB records and other documentation or determinate field surveys.

3.4 Sensitive Natural Communities
The Manual of California Vegetation, Second Edition (Sawyer et al., 2009) was used to describe vegetation communities onsite. Sensitive natural communities are those that are listed in the CNDDB.

4.0 RESULTS

4.1 Site Characteristics and Land Use
The Study Area is located on flat terrain in an area of rural residential and industrial/commercial development. The Study Area is situated at an elevational range of approximately 320 feet above mean sea level in the North Coast subregion of the Northwestern California region of the California floristic province (Baldwin et al. 2012). The average winter low temperature is 39.5 degrees )DKUHQKHLW Ü)

average summer high temperature is 90.7Ü); the average annual precipitation is approximately 43.13 inches (NOAA 2021b).

The Study Area is made up of undeveloped lands comprised of annual grassland and riparian wetland vegetation communities and seasonal wetland/roadside ditch habitat. There is an abandoned gravel/asphalt access road along the eastern edge of the annual grassland, and numerous old dirt spoils piles are in the southern portion of the annual grassland; the dirt piles are overgrown with weedy nonnative plants.

The riparian wetland is located in a low-lying area between the annual grassland onsite and an abandoned railroad spur along Railroad Avenue. This wetland does not appear to support flows except runoff along Asti Road. The vegetation was quite dense on the southern boundary of the Study Area along Railroad Avenue but thinned out along Asti Road.

The plant species composition of the annual grassland and riparian communities are described in detail in Section 4.2.

The surrounding lands include Asti Road and Highway 101, rural residences, undeveloped land, and a lumber processing plant.

Representative photographs of the Study Area are included in Attachment E.

4.2 Vegetation Communities
There are two vegetation communities or land cover types onsite (Figure 4-1). Annual grassland makes up the upland and most of the roadside portions of the Study Area, and riparian woodland/scrub is found along the southwestern and southern boundary. The annual grassland onsite most closely resembles the Avena species - Bromus species Herbaceous Semi-Natural Alliance (wild oats and annual brome grasslands) and the riparian woodland/scrub most close resembles the Populus fremontii - Fraxinus velutina - Salix gooddingii Forest & Woodland Alliance (Fremont cottonwood forest and woodland) as described in the Manual of California Vegetation, Second Edition (Sawyer et al. 2009). The wild oats and annual brome grassland does not have a state or global rarity rank according to CDFW and is not a sensitive natural community. The Fremont cottonwood forest and woodland has a state rank of S3.2 and a global rank of G4 and is a sensitive natural community according to CDFW.

The grassland onsite is comprised of a variety of non-native weedy plants including wild oat (Avena fatua), foxtail barley (Hordeum murinum), Italian ryegrass (Festuca perennis), soft brome (Bromus hordeaceus), narrow-leaved plantain (Plantago lanceolata), and prickly lettuce (Lactuca serriola). Much of the grassland onsite appears to be historically disturbed by grading or leveling. The Study Area appears to have been graded around 2004 according to Google Earth photos. The southern portion of the annual grassland was recently disturbed by heavy equipment that was used to move dirt spoil piles that were stockpiled in the southern portion of the annual grassland.

Arroyo willow (Salix lasiolepis) dominates the subcanopy, which also includes valley oak, interior live oak, and coast live oak. The understory is scattered with open to dense areas of Himalayan blackberry (Rubus armeniacus) and coyote bush (Baccharis pilularis).

4.3 Wildlife Observations and Movement/Corridors/Nursery Sites The Study Area is located in rural residential setting with Highway 101 and Asti Road to the west and cleared lands on a lumber processing operation to the south. Some wildlife use expected onsite, primarily commonly occurring birds in the riparian habitat.

During the site visit in March 2021, a variety of bird species were observed in the Study Area.

Representative wildlife species observed included American crow (Corvus brachyrhynchos), Brewer’s blackbird (Euphagus cyanocephalus), Anna’s hummingbird (Calypte anna), California scrub-jay (Aphelocoma californica), lesser goldfinch (Spinus psaltria), and yellow-rumped warbler (Setophaga coronata). Several California ground squirrel burrows (Spermophilus beecheyi) were seen in the dirt piles, and Sierran treefrog (Pseudacris sierra) were heard from the riparian vegetation.

4.4 Soils
According to the Web Soil Survey (NRCS 2021a), two soil units, or types, have been mapped within the Study Area (Figure 4-2):

JoG – Josephine loam, 50 to 75 percent slopes and
PcB – Pajaro clay loam, 2 to 5 percent slopes.

Neither of these soil units are derived from serpentinite or other ultramafic parent materials. The Josephine soil series consists of well-drained loams that have a clay loam subsoil; at a depth of 24 to over 60 inches they are underlain by weathered, fine-grained sandstone and shale (Soil Conservation Service [SCS] 1972). The Pajaro soil series consists of somewhat poorly drained fine sandy loams. These soils are underlain by mixed alluvial material derived from a variety of sedimentary sources. The soils are on low terraces and on alluvial flood plains and fans in valley areas (SCS 1972).

JoG-Josephine loam is does not have hydric inclusions or components and is not considered a hydric soil.

PcB-Pajaro clay loam has hydric components (Pajaro) on terraces and hydric inclusions (unnamed) in depressions (NRCS 2021b).

4.5 Aquatic Resources
An aquatic resources delineation was conducted for the Study Area. A total of 0.180 acre of aquatic resources have been mapped within the Study Area, including 0.020 acre of seasonal wetland swale and

0.160 acre of seasonal creek (Attachment C). The aquatic resources delineation has not been verified by the USACE and is subject to changes during the verification process. 296

4.6.6.1 Allen’s Hummingbird
Allen’s hummingbird (Selasphorus sasin) is not listed and protected under either the federal or California ESAs; however, it is considered a species of conservation concern according to the U.S. Fish and Wildlife Service. Allen’s hummingbirds breed along the Pacific Coast from Oregon to southern California (Clark and Mitchell 2020). Male breeding territories are located in open areas of coastal scrub or riparian vegetation, and females select nest sites in densely vegetated areas with some tree cover, such as mixed evergreen, Douglas fir, redwood, and Bishop pine forests; riparian woodlands; eucalyptus and cypress groves; live oak woodlands; and coastal scrub (Clark and Mitchell 2020). Nesting occurs during February through June.

There are no CNDDB occurrences of Allen’s hummingbird reported within five miles of the Study Area (CDFW 2021a). The scrub habitat and trees in the riparian habitat within the Study Area could provide nesting habitat for this species. Allen’s hummingbird has potential to occur onsite.

4.6.6.2 Cooper’s Hawk

The Study Area supports potential nesting habitat for a variety of common birds protected under the MBTA and California Fish and Game Code § 3503, among others.

4.6.7 Mammals
Four special-status mammal species were identified as having the potential to occur within the Study Area based on the literature review (Table 4-1). However, upon further analysis and after the site visit, only the Sonoma tree vole (Arborimus pomo) was considered to be absent from the site due to the lack of suitable habitat. No further discussion of this species is provided within this assessment. A brief description of the remaining three special-status bat species that have the potential to occur within the Study Area is presented below.

4.6.7.1 Pallid Bat
The pallid bat (Antrozous pallidus) is not listed pursuant to either the California or federal ESAs; however, this species is considered a 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 317

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 2021).

There is one CNDDB occurrence of pallid bat reported within five miles of the Study Area (CDFW 2021a).

The trees in the riparian scrub within and surrounding the Study Area could support suitable roosting habitat for this species.

4.6.7.2 Townsend’s Big-Eared Bat
The Townsend’s big-eared bat (Corynorhinus townsendii) is not listed pursuant to either the California or federal ESAs; however, this species is considered a SSC by CDFW. Townsend’s big-eared bat is a fairly large bat with prominent bilateral noes lumps and large “rabbit-like” ears. This species occurs throughout the west and ranges from the southern portion of British Columbia south along the Pacific coast to central Mexico and east into the Great Plains. This species has been reported from a wide variety of habitat types and elevations from sea level to 10,827 feet. Habitats used include coniferous forests, mixed meso-phytic forests, deserts, native prairies, riparian communities, active agricultural areas, and coastal habitat types.

Its distribution is strongly associated with the availability of caves and cave-like roosting habitat including abandoned mines, buildings, bridges, rock crevices, and hollow trees. This species is readily detectable when roosting due to their habit of roosting pendant-like on open surfaces. Townsend’s big-eared bat is a moth specialist with over 90 percent of its diet composed of Lepidopterans. Foraging habitat is generally edge habitats along streams adjacent to and within a variety of wooded habitats. This species often travels long distances when foraging and large home ranges have been documented in California (WBWG 2021).

There is one CNDDB occurrence of Townsend’s big-eared bat reported within five miles of the Study Area (CDFW 2021a). The trees in the riparian scrub within and surrounding the Study Area could support suitable roosting habitat for this species.

4.6.7.3 Western Red Bat
The western red bat (Lasiurus blossevillii) is not listed pursuant to either the California or federal ESAs; however, this species is considered a SSC by CDFW. The western red bat is easily distinguished from other western bat species by its distinctive red coloration. This species is broadly distributed; its range extending from southern British Columbia in Canada through much of the western U.S. to Argentina and Chile in South America. This solitary species day-roosts primarily in the foliage of trees or shrubs in edge habitats bordering streams or open fields, in orchards, and occasionally urban areas. They may be associated with intact riparian habitat, especially with willows, cottonwoods, and sycamores. This species may occasionally utilize caves for roosting as well. They feed on a variety of insects, and generally begin to forage one to two hours after sunset. This species is considered highly migratory; however, the timing of migration and the summer ranges of males and females may be different. Winter behavior of this species is poorly understood (WBWG 2021).

4.7 Sensitive Natural Communities
The Fremont cottonwood forest and woodland onsite has a state rank of S3.2, a global rank of G4, and is a sensitive natural community according to CDFW.

5.0 IMPACT ANALYSIS
This section specifically addresses the questions raised by the CEQA - Appendix G Environmental Checklist Form, IV. Biological Resources. This impact analysis assumes the Project will implement measures that fulfill the intent of recommended measures described in Section 6.0.

5.1 Special Status Species
Would the Project result in effects, either directly or through habitat modifications, to species identified as a candidate, sensitive, or special-status species in local or regional plans, policies, or regulations, or by the CDFW or USFWS?
No special-status species are known to occur within the Study Area; however, special-status animal surveys have not been conducted. The Study Area includes potential habitat for special-status species within the impact area. Potential effects to special-status species are summarized in the following sections by taxonomic group or species.

5.1.1 Special-Status and Other Protected Birds
There is no potential habitat for federally or state-listed bird species in the Study Area, However, the Study Area supports potential habitat for five non-listed special-status bird species and a variety of other birds that are protected under the MBTA and the California Fish and Game Code. Project development could permanently remove or alter upland nesting and foraging habitat in the development area, and Project construction would generate a temporary disturbance that would likely displace foraging birds from the riparian habitat during construction. Permanent removal or alteration of a minimal amount of habitat and displacement of foraging birds during construction is not expected to significantly impact special-status birds.

Implementation of recommendations BIO-2 and BIRD-1 described in Section 6.0 would avoid or minimize potential effects to special-status birds and other protected birds.

5.1.2 Special-Status Mammals
Three non-listed special-status bats have potential to occur in the Study Area. Removal of trees may directly impact roosting habitat. Project development would permanently remove a minimal amount of potential roosting and foraging habitat in the development area, and Project construction would generate a temporary disturbance during the day that would likely displace day-roosting bats from the Study Area. 319

Permanent removal of a minimal amount of potential roosting or foraging habitat and displacement of day-roosting bats during construction is not expected to significantly impact special-status bats.

Implementation of recommendations BIO-2 and BAT-1 described in Section 6.0 would avoid or minimize potential effects to special-status bats.

5.2 Riparian Habitat and Sensitive Natural Communities
Would the Project have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations or by the California Department of Fish and Game or US Fish and Wildlife Service? The Fremont cottonwood forest and woodland onsite has a state rank of S3.2 and a global rank of G4 and is a sensitive natural community according to CDFW. The Fremont cottonwood forest and woodland onsite currently surrounds the mapped seasonal creek and is bordered by Asti Road on the west and a historical railroad on the south. The current site plan (Attachment A) will result in permanent impacts (removal) of approximately 0.125-acre of riparian woodland. Note, impact acreage is approximate as impacts have been calculated using the site plan and are subject to change once grading plans are finalized. Additionally, riparian canopy is mapped using aerial imagery and is subject to modification based on current ground conditions during Project implementation. Impacts to riparian woodland are limited to small infringements into the northern extent of the riparian woodland that occurs along the southern boundary of the Project (Attachment A). The Project is being designed to minimize impacts to riparian woodland to the extent practicable, and a large portion of the existing riparian woodland surrounding the seasonal creek would be avoided by the Project. Implementation of recommendations BIO-1 and RIP-1 described in Section 6.0 would further minimize potential effects to riparian habitat and sensitive natural communities.

5.3 Aquatic Resources, Including Waters of the U.S. and State Would the Project have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act CWA (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? Based on aquatic resources delineation conducted for the Study Area, it is likely that federally protected wetlands are present onsite. The current site plan (Attachment A) avoids all aquatic resources. A free-span bridge will be construction across the seasonal creek; however, all impacts associated with the bridge will be above the OHWM of the creek. If changes to the site plan occur that result in impacts federally and state protected aquatic resources, implementation of recommendations BIO-1 and WATERS-1, WATERS-2, WATERS-3, described in Section 6.0 would avoid or minimize potential effects to protected aquatic resources, including Waters of the U.S. and State.

5.4 Wildlife Movement/Corridors
Would the Project interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites?
The Study Area provides limited migratory opportunities for terrestrial wildlife because of the adjacent rural residences, Asti Road and Highway 101, and the lumber processing operations to the south. Project construction is likely to temporarily disturb and displace some wildlife from the Study Area. Some wildlife such as birds or nocturnal species are likely to continue to use the habitats opportunistically for the duration of construction. Once construction is complete, wildlife movements are expected to resume but will likely be more limited through the developed areas of the Study Area. The Project is not expected to substantially interfere with wildlife movement.

There are no documented nursery sites and no nursery sites were observed within the Study Area during the site reconnaissance. Therefore, the Project is not expected to impact wildlife nursery sites.

5.5 Local Policies, Ordinances, and Other Plans
Does the Project conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance?
Coast live oak, interior live oak, and valley oak trees are present within the riparian community in the Study Area. The Project may impact trees protected under the City of Cloverdale’s Tree Preservation Ordinance. Implementation of recommendations RIP-1 described in Section 6.0 would avoid or minimize potential effects to protected trees.

Does the Project conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan?
The Study Area is not covered by any local, regional, or state conservation plan. Therefore, the Project would not conflict with a local, regional, or state conservation plan.

6.0 RECOMMENDATIONS
This section summarizes recommended measures to avoid, minimize, or compensate for potential impacts to biological resources from the proposed Project.

6.1 General Recommendations
The following general measures are recommended to avoid impacts to offsite and onsite biological resources:

BIO-1: The project should implement erosion control measures and best management practices to reduce the potential for sediment or pollutants at the Project site. Examples of appropriate measures are included below.
321

2020-228
Erosion control measures should be placed between Paradise Lake and the outer edge of the impact limits prior to commencement of construction activities. Such identification and erosion control measures should be properly maintained until construction is completed and the soils have been stabilized.

Any fueling in the Study Area should use appropriate secondary containment techniques to prevent spills.

BIO-2: A qualified biologist should conduct a mandatory Worker Environmental Awareness Program for all contractors, work crews, and any onsite personnel to aid workers in recognizing special-status species and sensitive biological resources that may occur onsite. The program shall include identification of the special-status species and their habitats, a description of the regulatory status and general ecological characteristics of sensitive resources, and review of the limits of construction and Mitigation Measures required to reduce impacts to biological resources within the work area.

6.2 Riparian Habitat and Sensitive Natural Communities
For impacts to riparian vegetation, sensitive natural communities, or habitat subject to Section 1600 of the Fish and Game code, the following measure is recommended:

RIP-1: Prepare an LSA Notification to CDFW under California Fish and Game Code Section 1602 to request authorization to impact regulated aquatic features. Work with CDFW to develop compensatory mitigation for loss of riparian vegetation/sensitive natural communities.

Compensatory mitigation may include planting of riparian vegetation onsite or at an offsite location or purchase of mitigation credits from an approved mitigation bank.

6.3 Waters of the U.S./State
There are Waters of the U.S./State present within the Study Area. If there are any proposed impacts to the Waters of the U.S./State, the following measures are recommended:

WATERS-1: File a request for authorization to fill wetlands and other Waters of the U.S. under Section 404 of the federal CWA (Section 404 Permit) 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 process to ensure no net loss of wetland function and values. To facilitate such authorization, an application for a Section 404 Nationwide Permit for the Project should be prepared and submitted to USACE. 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.

WATERS-2: File a request for a Water Quality Certification or waiver pursuant to Section 401 of the CWA must be obtained from the RWQCB for Section 404 permit actions.

WATERS-3: Pursuant to the Porter-Cologne Water Quality Act, a permit authorization from the RWQCB is required prior to the discharge of material in an area that could affect Waters of the State. 322

Mitigation requirements for discharge to Waters of the State within the Project site will be developed in consultation with the RWQCB.

6.4 Wildlife Movement/Corridors/Nursery Sites
No impacts to wildlife movement, corridors, or nursery sites are expected.

6.5 Special-Status Species
There is potentially suitable habitat within the Study Area for five special-status birds and three specialstatus mammals. None of these eight potentially occurring special-status species are candidates or fully listed and protected under the California and federal ESAs. A brief discussion of recommended avoidance and minimization measures is presented below for each group.

6.5.1 Special-Status Birds and Migratory Bird Treaty Act-Protected Birds For Project activities with potential to affect active bird nests, the following measures are recommended.

BIRD-1: If construction is to occur during the nesting season (generally February 1 through August 31), conduct a preconstruction nesting bird survey of all suitable nesting habitat on the Project within 14 days of the commencement of construction. The survey shall be conducted within a 500-foot radius of Project work areas for raptors and within a 100-foot radius for other nesting birds. If any active nests are observed, these nests shall be designated a sensitive area and protected by an avoidance buffer established in coordination with CDFW until the breeding season has ended or until a qualified biologist has determined that the young have fledged and are no longer reliant upon the nest or parental care for survival.

Preconstruction nesting surveys are not required for construction activity outside the nesting season.

6.5.2 Special-Status Bats
There is potential for three special-status bats to occur within the Study Area, and the majority of the Study Area is planned for impact. The following measure is recommended to minimize potential impacts to special-status bats.

BAT-1: Within 14 days prior to Project activities that may impact bat roosting habitat (e.g., removal of manmade structures or trees), a qualified biologist will survey for all suitable roosting habitat within the Project impact limits. If suitable roosting habitat is not identified, no further measures are necessary. 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 roosting bats are determined to be present within the Project site, consultation with CDFW prior to initiation of construction activities or preparation of a Bat Management Plan outlining avoidance and minimization measures specific to the potentially affected roost(s) may be required.

IPaC resource list
This report is an automatically generated list of species and other resources such as critical habitat (collectively referred to as trust resources) under the U.S. Fish and Wildlife Service's (USFWS) jurisdiction that are known or expected to be on or near the project area referenced below. The list may also include trust resources that occur outside of the project area, but that could potentially be directly or indirectly aàected by activities in the project area. However, determining the likelihood and extent of eàects a project may have on trust resources typically requires gathering additional site-speciÕc (e.g., vegetation/species surveys) and project-speciÕc (e.g., magnitude and timing of proposed activities) information.

Below is a summary of the project information you provided and contact information for the USFWS oÞce(s) with jurisdiction in the deÕned project area. Please read the introduction to each section that follows (Endangered Species, Migratory Birds, USFWS Facilities, and NWI Wetlands) for additional information applicable to the trust resources addressed in that section.

Endangered species
This resource list is for informational purposes only and does not constitute an analysis of project level impacts.

The primary information used to generate this list is the known or expected range of each species.

Additional areas of inÖuence (AOI) for species are also considered. An AOI includes areas outside of the species range if the species could be indirectly aàected by activities in that area (e.g., placing a dam upstream of a Õsh population even if that Õsh does not occur at the dam site, may indirectly impact the species by reducing or eliminating water Öow downstream). Because species can move, and site conditions can change, the species on this list are not guaranteed to be found on or near the project area. To fully determine any potential eàects to species, additional site-speciÕc and project-speciÕc information is often required.

Section 7 of the Endangered Species Act requires Federal agencies to "request of the Secretary information whether any species which is listed or proposed to be listed may be present in the area of such proposed action" for any project that is conducted, permitted, funded, or licensed by any Federal agency. A letter from the local oÞce and a species list which fulÕlls this requirement can only be obtained by requesting an oÞcial species list from either the Regulatory Review section in IPaC (see directions below) or from the local Õeld oÞce directly.

For project evaluations that require USFWS concurrence/review, please return to the IPaC website and request an oÞcial species list by doing the following:

1. Draw the project location and click CONTINUE.

2. Click DEFINE PROJECT.

3. Log in (if directed to do so).

4. Provide a name and description for your project.

5. Click REQUEST SPECIES LIST.

Listed species and their critical habitats are managed by the Ecological Services Program of the U.S.

The graphs below provide our best understanding of when birds of concern are most likely to be present in your project area. This information can be used to tailor and schedule your project activities to avoid or minimize impacts to birds. Please make sure you read and understand the FAQ "Proper Interpretation and Use of Your Migratory Bird Report" before using or attempting to interpret this report.

Probability of Presence ( )
Each green bar represents the bird's relative probability of presence in the 10km grid cell(s) your project overlaps during a particular week of the year. (A year is represented as 12 4-week months.) A taller bar indicates a higher probability of species presence. The survey eàort (see below) can be used to establish a level of conÕdence in the presence score. One can have higher conÕdence in the presence score if the corresponding survey eàort is also high.

How is the probability of presence score calculated? The calculation is done in three steps:

1. The probability of presence for each week is calculated as the number of survey events in the week where the species was detected divided by the total number of survey events for that week. For example, if in week 12 there were 20 survey events and the Spotted Towhee was found in 5 of them, the probability of presence of the Spotted Towhee in week 12 is 0.25.

2. To properly present the pattern of presence across the year, the relative probability of presence is calculated. This is the probability of presence divided by the maximum probability of presence across all weeks. For example, imagine the probability of presence in week 20 for the Spotted Towhee is 0.05, and that the probability of presence at week 12 (0.25) is the maximum of any week of the year. The relative probability of presence on week 12 is 0.25/0.25 = 1; at week 20 it is

0.05/0.25 = 0.2.

3. The relative probability of presence calculated in the previous step undergoes a statistical conversion so that all possible values fall between 0 and 10, inclusive. This is the probability of presence score.

To see a bar's probability of presence score, simply hover your mouse cursor over the bar.

Breeding Season ( )
Yellow bars denote a very liberal estimate of the time-frame inside which the bird breeds across its entire range. If there are no yellow bars shown for a bird, it does not breed in your project area.

Survey Eàort ( )
Vertical black lines superimposed on probability of presence bars indicate the number of surveys performed for that species in the 10km grid cell(s) your project area overlaps. The number of surveys is expressed as a range, for example, 33 to 64 surveys.

To see a bar's survey eàort range, simply hover your mouse cursor over the bar.

No Data ( )
A week is marked as having no data if there were no survey events for that week.

Survey Timeframe
Surveys from only the last 10 years are used in order to ensure delivery of currently relevant information. The exception to this is areas oà the Atlantic coast, where bird returns are based on all years of available data, since data in these areas is currently much more sparse.

Nationwide Conservation Measures describes measures that can help avoid and minimize impacts to all birds at any location year round. Implementation of these measures is particularly important when birds are most likely to occur in the project area. When birds may be breeding in the area, identifying the locations of any active nests and avoiding their destruction is a very helpful impact minimization measure. To see when birds are most likely to occur and be breeding in your project area, view the Probability of Presence Summary. Additional measures or permits may be advisable depending on the type of activity you are conducting and the type of infrastructure or bird species present on your project site.

What does IPaC use to generate the migratory birds potentially occurring in my speciÕed location? The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern (BCC) and other species that may warrant special attention in your project location.

The migratory bird list generated for your project is derived from data provided by the Avian Knowledge Network (AKN). The AKN data is based on a growing collection of survey, banding, and citizen science datasets and is queried and Õltered to return a list of those birds reported as occurring in the 10km grid cell(s) which your project intersects, and that have been identiÕed as warranting special attention because they are a BCC species in that area, an eagle (Eagle Act requirements may apply), or a species that has a particular vulnerability to oàshore activities or development.

Again, the Migratory Bird Resource list includes only a subset of birds that may occur in your project area. It is not representative of all birds that may occur in your project area. To get a list of all birds potentially present in your project area, please visit the AKN Phenology Tool.

What does IPaC use to generate the probability of presence graphs for the migratory birds potentially occurring in my speciÕed location?
The probability of presence graphs associated with your migratory bird list are based on data provided by the Avian Knowledge Network (AKN). This data is derived from a growing collection of survey, banding, and citizen science datasets .

Probability of presence data is continuously being updated as new and better information becomes available. To learn more about how the probability of presence graphs are produced and how to interpret them, go the Probability of Presence Summary and then click on the "Tell me about these graphs" link.

How do I know if a bird is breeding, wintering, migrating or present year-round in my project area? To see what part of a particular bird's range your project area falls within (i.e. breeding, wintering, migrating or year-round), you may refer to the following resources: The Cornell Lab of Ornithology All About Birds Bird Guide, or (if you are unsuccessful in locating the bird of interest there), the Cornell Lab of Ornithology Neotropical Birds guide. If a bird on your migratory bird species list has a breeding season associated with it, if that bird does occur in your project area, there may be nests present at some point within the timeframe speciÕed. If "Breeds elsewhere" is indicated, then the bird likely does not breed in your project area.

What are the levels of concern for migratory birds?
Migratory birds delivered through IPaC fall into the following distinct categories of concern:

1. "BCC Rangewide" birds are Birds of Conservation Concern (BCC) that are of concern throughout their range anywhere within the USA (including Hawaii, the PaciÕc Islands, Puerto Rico, and the Virgin Islands);

2. "BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation Regions (BCRs) in the continental USA; and

3. "Non-BCC - Vulnerable" birds are not BCC species in your project area, but appear on your list either because of the Eagle Act requirements (for eagles) or (for non-eagles) potential susceptibilities in oàshore areas from certain types of development or activities (e.g. oàshore energy development or longline Õshing). (AKN). The AKN data is based on a growing collection of survey, banding, and citizen science datasets y, g, and is queried and Õltered to return a list of those birds reported as occurring in the 10km grid cell(s) which your project intersects, and that have been identiÕed as warranting special attention because they are a BCC species in that area, an eagle (Eagle Act g requirements may apply), or a species that has a particular vulnerability to oàshore activities or development.

Although it is important to try to avoid and minimize impacts to all birds, eàorts should be made, in particular, to avoid and minimize impacts to the birds on this list, especially eagles and BCC species of rangewide concern. For more information on conservation measures you can implement to help avoid and minimize migratory bird impacts and requirements for eagles, please see the FAQs for these topics.

Details about birds that are potentially aàected by oàshore projects For additional details about the relative occurrence and abundance of both individual bird species and groups of bird species within your project area oà the Atlantic Coast, please visit the Northeast Ocean Data Portal. The Portal also oàers data and information about other taxa besides birds that may be helpful to you in your project review.

Alternately, you may download the bird model results Õles underlying the portal maps through the NOAA NCCOS Integrative Statistical Modeling and Predictive Mapping of Marine Bird Distributions and Abundance on the Atlantic Outer Continental Shelf project webpage.

Bird tracking data can also provide additional details about occurrence and habitat use throughout the year, including migration. Models relying on survey data may not include this information. For additional information on marine bird tracking data, see the Diving Bird Study and the nanotag studies or contact Caleb Spiegel or Pam Loring.

What if I have eagles on my list?
If your project has the potential to disturb or kill eagles, you may need to obtain a permit to avoid violating the Eagle Act should such impacts occur.

Proper Interpretation and Use of Your Migratory Bird Report The migratory bird list generated is not a list of all birds in your project area, only a subset of birds of priority concern. To learn more about how your list is generated, and see options for identifying what other birds may be in your project area, please see the FAQ "What does IPaC use to generate the migratory birds potentially occurring in my speciÕed location". Please be aware this report provides the "probability of presence" of birds within the 10 km grid cell(s) that overlap your project; not your exact project footprint. On the graphs provided, please also look carefully at the survey eàort (indicated by the black vertical bar) and for the existence of the "no data" indicator (a red horizontal bar). A high survey eàort is the key component. If the survey eàort is high, then the probability of presence score can be viewed as more dependable. In contrast, a low survey eàort bar or no data bar means a lack of data and, therefore, a lack of certainty about presence of the species. This list is not perfect; it is simply a starting point for identifying what birds of concern have the potential to be in your project area, when they might be there, and if they might be breeding (which means nests might be present). The list helps you know what to look for to conÕrm presence, and helps guide you in knowing when to implement conservation measures to avoid or minimize potential impacts from your project activities, should presence be conÕrmed. To learn more about conservation measures, visit the FAQ "Tell me about conservation measures I can implement to avoid or minimize impacts to migratory birds" at the bottom of your migratory bird trust resources page.

Any activity proposed on lands managed by the National Wildlife Refuge system must undergo a 'Compatibility Determination' conducted by the Refuge. Please contact the individual Refuges to discuss any questions or concerns.

Bird tracking data can also provide additional details about occurrence and habitat use throughout the year, including migration. Models relying on survey data may not include this information. For additional information on marine bird tracking data, see the Diving Bird Study g and the nanotag studies g or contact Caleb Spiegel or Pam Loring.

THERE ARE NO KNOWN WETLANDS AT THIS LOCATION.

Data limitations
The Service's objective of mapping wetlands and deepwater habitats is to produce reconnaissance level information on the location, type and size of these resources. The maps are prepared from the analysis of high altitude imagery. Wetlands are identiÕed based on vegetation, visible hydrology and geography. A margin of error is inherent in the use of imagery; thus, detailed on-the-ground inspection of any particular site may result in revision of the wetland boundaries or classiÕcation established through image analysis.

The accuracy of image interpretation depends on the quality of the imagery, the experience of the image analysts, the amount and quality of the collateral data and the amount of ground truth veriÕcation work conducted.

Metadata should be consulted to determine the date of the source imagery used and any mapping problems.

Wetlands or other mapped features may have changed since the date of the imagery or Õeld work. There may be occasional diàerences in polygon boundaries or classiÕcations between the information depicted on the map and the actual conditions on site.

Data exclusions
Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and nearshore coastal waters.

Some deepwater reef communities (coral or tuberÕcid worm reefs) have also been excluded from the inventory.

These habitats, because of their depth, go undetected by aerial imagery.

Data precautions
Federal, state, and local regulatory agencies with jurisdiction over wetlands may deÕne and describe wetlands in a diàerent manner than that used in this inventory. There is no attempt, in either the design or products of this inventory, to deÕne the limits of proprietary jurisdiction of any Federal, state, or local government or to establish the geographical scope of the regulatory programs of government agencies. Persons intending to engage in activities involving modiÕcations within or adjacent to wetland areas should seek the advice of appropriate federal, state, or local agencies concerning speciÕed agency regulatory programs and proprietary jurisdictions that may aàect such activities.

Impacts to NWI wetlands and other aquatic habitats may be subject to regulation under Section 404 of the Clean Water Act, or other State/Federal statutes.

1.0 INTRODUCTION
On behalf of the Pacific Companies, ECORP Consulting, Inc. conducted an aquatic resources delineation for the Alexander Valley Cloverdale Housing Project (Project) located in Sonoma County, California (Figure

1. Project Location and Vicinity). The approximately 3.43-acre Study Area corresponds to an unsectioned portion of the Rincon de Musalacon land grant within the “Cloverdale, California” 7.5-minute quadrangle (U.S. Geological Survey [USGS] 1960, photorevised 1975). The approximate center of the Study Area is located at 38.804580° latitude and -123.010836° longitude within the Russian Watershed (Hydrologic Unit Code #18010110; Natural Resources Conservation Service [NRCS], USGS, and U.S. Environmental Protection Agency [USEPA] 2016). Driving directions from Sacramento to the Study Area are included as Attachment A.

This report describes aquatic resources identified within the Study Area that may be regulated by the U.S.

Army Corps of Engineers (USACE) pursuant to Section 404 of the federal Clean Water Act (CWA). The information presented in this report provides data required by the USACE San Francisco District’s Minimum Standards for Acceptance of Aquatic Resources Delineation Reports (USACE 2016a). The aquatic resource boundaries depicted in this report represent a calculated estimation of the jurisdictional area within the Study Area and are subject to modification following the USACE verification process.

The purpose of this report is to provide adequate information to USACE for the issuance of a Preliminary Jurisdictional Determination (PJD).

2.0 REGULATORY SETTING

2.1 Waters of the United States
This report describes aquatic resources, including wetlands, that may be regulated by USACE under Section 404 of the federal CWA. The following sections define these regulations.

2.1.1 Wetlands
Wetlands are “those areas that are inundated or saturated by surface or groundwater 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” (51 Federal Register [FR] 41250, Nov. 13, 1986, as amended at 58 FR 45036, Aug. 25, 1993). Wetlands can be perennial or intermittent.

2.1.2 Other Waters
Other waters are nontidal, perennial, and intermittent watercourses and tributaries to such watercourses (51 FR 41250, Nov. 13, 1986, as amended at 58 FR 45036, August 25, 1993). The limit of USACE jurisdiction for nontidal watercourses (without adjacent wetlands) is defined in 33 Code of Federal Regulations (CFR) 328.4(c)(1) as the “ordinary high water mark” (OHWM). The OHWM is defined as the “line on the shore established by the fluctuations of water and indicated by physical characteristics such as clear, natural line impressed on the bank, shelving, changes in the character of soil, destruction of terrestrial vegetation, the

presence of litter and debris, or other appropriate means that consider the characteristics of the surrounding areas” approximation of the lateral limit of USACE jurisdiction. The upstream limits of other waters are defined as the point where the OHWM is no longer perceptible.

2.2 Clean Water Act
The USACE regulates discharge of dredged or fill material into Waters of the U.S. under Section 404 of the CWA. “Discharges of fill material” is defined as the addition of fill material into Waters of the U.S., including, but not limited to, the following: placement of fill necessary for the construction of any structure, or impoundment requiring rock, sand, dirt, or other material for its construction; sitedevelopment fills for recreational, industrial, commercial, residential, and other uses; causeways or road fills; and fill for intake and outfall pipes, and subaqueous utility lines” (33 CFR § 328.2(f)). In addition, Section 401 of the CWA (33 U.S. Code 1341) requires any applicant for a federal license or permit to conduct any activity that may result in a discharge of a pollutant into Waters of the U.S. to obtain a certification that the discharge will comply with the applicable effluent limitations and water quality standards.

Substantial impacts to wetlands (over 0.5 acre of impact) may require an individual permit. Projects that only minimally affect wetlands (less than 0.5 acre of impact) may meet the conditions of one of the existing Nationwide Permits. 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.

2.3 Section 10 of the Rivers and Harbors Act
Section 10 of the Rivers and Harbors Act of 1899 requires authorization from the Secretary of the Army, acting through the USACE, for the construction of any structure in or over any navigable Waters of the U.S. Structures or work outside the limits defined for navigable Waters of the U.S. require a Section 10 permit if the structure or work affects the course, location, or condition of the water body. The law applies to any dredging or disposal of dredged materials, excavation, filling, re-channelization, or any other modification of a navigable water of the U.S., and applies to all structures, from the smallest floating dock to the largest commercial undertaking. It further includes, without limitation, any wharf, dolphin, weir, boom breakwater, jetty, groin, bank protection (e.g., riprap, revetment, bulkhead), mooring structures such as pilings, aerial or subaqueous power transmission lines, intake or outfall pipes, permanently moored floating vessel, tunnel, artificial canal, boat ramp, aids to navigation, and any other permanent, or semi-permanent obstacle or obstruction.

2.4 Jurisdictional Assessment
Pursuant to the U.S. Environmental Protection Agency (USEPA) and USACE memorandum regarding CWA jurisdiction, issued following the United States Supreme Court’s decision in the consolidated cases Rapanos v. United States and Carabell v. United States (herein referred to as Rapanos), the agencies will assert jurisdiction over the following waters: “Traditional Navigable Waters” (TNW), all wetlands adjacent to TNWs, non-navigable tributaries of TNWs that are “relatively permanent” waters (RPW) (i.e., tributaries 350
$TXDWLF5HVRXUFHV'HOLQHDWLRQ

Alexander Valley Cloverdale Housing Project 4 September 24, 2021 2020-228
that typically flow year-round or have continuous flow at least seasonally), and wetlands that directly abut such tributaries (USEPA and USACE 2007).

Waters requiring a significant nexus determination by the USACE and USEPA to establish jurisdiction include non-navigable tributaries that are not relatively permanent, wetlands adjacent to non-navigable tributaries that are not relatively permanent, and wetlands adjacent to but do not directly abut a relatively permanent non-navigable tributary (USEPA and USACE 2007). The jurisdictional determination is a factbased evaluation to establish whether a water has a significant nexus with a TNW. The significant nexus analysis will assess the flow characteristics and functions of the non-navigable tributary itself and the functions performed by all wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity of downstream TNWs (USEPA and USACE 2007). PorterCologne 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 storm water 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 the 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).

3.0 METHODS
This aquatic resources delineation was conducted in accordance with the Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory 1987), the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Arid West Region (Arid West Region Supplement) (USACE 2008a), and A Field Guide to the Identification of the Ordinary High Water Mark (OHWM) in the Arid West Region of the Western United States (OHWM Guide; USACE 2008b).

The boundaries of aquatic resources were delineated through standard field methods (e.g., paired sample set analyses), OHWM transects, and aerial photograph interpretation. Field data were recorded on Wetland Determination Data Forms - Arid West Region or Arid West OHWM Data Forms (Attachment B).

A color aerial ESRI imagery (accessed April 2021) was used to assist with mapping and ground-truthing.

Munsell Soil Color Charts (Munsell Color 2009) and the Web Soil Survey (NRCS 2021a) were used to aid in identifying hydric soils in the field. The Jepson Manual, 2nd Edition (Baldwin et al. 2012) was used for plant nomenclature and identification.

The field survey was conducted on April 22, 2021 by ECORP biologists Emily Mecke and Hannah Stone.

The biologists walked accessible areas of the Study Area to determine the location and extent of aquatic 351

resources. Paired locations were sampled to evaluate whether or not the vegetation, hydrology, and soils data supported an aquatic resource determination. At each paired location, one point was located such that it was within the estimated aquatic resource area, and the other point was situated outside the limits of the estimated aquatic resource area. Additional non-paired points were taken in suspect areas to document upland conditions. Arid West OHWM Data Forms were used to document the OHWM of aquatic resources. Aquatic resources within the Study Area were recorded in the field using a postprocessing capable Global Positioning System (GPS) unit with sub-meter accuracy (Apple iPad, Collector for ArcGIS app with EOS Arrow 100 submeter GPS unit with real-time correction).

3.1 Routine Determinations for Wetlands
To be determined a wetland, the following three criteria must be met:

A majority of dominant vegetation species are wetland-associated species.

Hydrologic conditions exist that result in periods of flooding, ponding, or saturation during the growing season.

Hydric soils are present.

3.1.1 Vegetation
Hydrophytic vegetation is defined as the sum total of macrophytic plant life that occurs in areas where the frequency and duration of inundation or soil saturation produce permanent or periodically saturated soils of sufficient duration to exert a controlling influence on the plant species present (Environmental Laboratory 1987). The definition of wetlands includes the phrase "a prevalence of vegetation typically adapted for life in saturated soil conditions." Prevalent vegetation is characterized by the dominant plant species comprising the plant community (Environmental Laboratory 1987). The dominance test is the basic hydrophytic vegetation indicator and was applied at each sampling point location. The "50/20 rule" was used to select the dominant plant species from each stratum of the community. The rule states that for each stratum in the plant community, dominant species are the most abundant plant species (when ranked in descending order of coverage and cumulatively totaled) that immediately exceed 50 percent of the total coverage for the stratum, plus any additional species that individually comprise 20 percent or more of the total cover in the stratum (USACE 1992, 2008a).

Dominant plant species observed at each sampling point were then classified according to their indicator status (probability of occurrence in wetlands; Table 1), North American Digital Flora: National Wetland Plant List (Lichvar et al. 2016; Lichvar et al. 2018). If the majority (more than 50 percent) of the dominant vegetation on a site are classified as obligate (OBL), facultative wetland (FACW), or facultative (FAC), the site was considered to be dominated by hydrophytic vegetation. 352

In instances where indicators of hydric soil and wetland hydrology were present, but the plant community failed the dominance test, the vegetation was re-evaluated using the Prevalence Index. The Prevalence Index is a weighted-average wetland indicator status of all plant species in the sampling plot, where each indicator status category is given a numeric code (OBL=1, FACW=2, FAC=3, FACU=4, and UPL=5) and weighting is by abundance (percent cover). If the plant community failed the Prevalence Index, the presence/absence of plant morphological adaptations to prolonged inundation or saturation in the root zone was evaluated.

3.1.2 Soils
A hydric soil is defined as a soil that formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part (NRCS 2003).

Indicators that a hydric soil is present include, but are not limited to, histosols, histic epipedon, hydrogen sulfide, depleted below dark surface, sandy redox, loamy gleyed matrix, depleted matrix, redox dark surface, redox depressions, and vernal pools.

At each sampling point a soil pit was excavated to the depth needed to document an indicator, to confirm the absence of indicators, or until refusal at each sampling point. The soil was then examined for hydric soil indicators. Soil colors were determined while the soil was moist using the Munsell Soil Color Charts (Munsell Color 2009). Hydric soils are formed predominantly by the accumulation or loss of iron, manganese, sulfur, or carbon compounds in a saturated and anaerobic environment. These processes and the features in the soil that develop can be identified by looking at the color and texture of the soils.

3.1.3 Hydrology
Wetlands, by definition, are seasonally or perennially inundated or saturated at or near (within 12 inches of) the soil surface. Primary indicators of wetland hydrology include, but are not limited to, visual observation of saturated soils, visual observation of inundation, surface soil cracks, inundation visible on aerial imagery, water-stained leaves, oxidized rhizospheres along living roots, aquatic invertebrates, water marks (secondary indicator in riverine environments), drift lines (secondary indicator in riverine environments), and sediment deposits (secondary indicator in riverine environments). The occurrence of one primary indicator is sufficient to conclude that wetland hydrology is present. If no primary indicators are observed, two or more secondary indicators are required to conclude wetland hydrology is present. 353

Secondary indicators include, but are not limited to, drainage patterns, crayfish burrows, FAC-neutral test, and shallow aquitard.

3.2 Ordinary High-Water Mark/Non-Wetland Waters
The discussion in this section briefly summarizes the OHWM Guide (USACE 2008b). The OHWM Guide is intended for delineating ephemeral/intermittent channels. OHWM indicators commonly found in the Arid West include a clear natural scour line impressed on the bank, recent bank erosion, destruction of native terrestrial vegetation, and the presence of litter and debris. Resources needed to delineate OHWM include aerial photography and other imagery, topographic maps and other maps (e.g., geological, soil, vegetation), rainfall data, stream gage data, and existing delineations (if present). Field identification of the OHWM includes noting general impression of the vegetation species and distribution, geomorphic features present, surrounding upland land use, and hydrologic alterations and instream and floodplain structures. In the field, the process of delineating the OHWM includes the identification of a low-flow channel (if present), a transition to an active floodplain, and an active floodplain through the presence of geomorphic features (e.g., presence of an active floodplain, benches, break in bank slope, staining of rocks, litter, or drift) and vegetation indicators (e.g., presence of sparse/low vegetation, annual herbs, hydromesic ruderals, pioneer tree seedlings and saplings, xeroriparian species).

3.3 Weather Conditions During Survey
Weather conditions for the survey were ideal, with partly cloudy skies and temperatures ranging from 60 to 70 degrees Fahrenheit

.

3.4 Limitations of the Survey
Limitations of the survey included the following:

Portions of the Survey Area were inaccessible due to dense riparian vegetation or steep/unstable banks. The limits of aquatic resources in these inaccessible areas were mapped in the field from nearby accessible locations, usually the top of the bank, and/or mapped from aerial imagery.

3.5 Previous Delineation
The Study Area overlaps with a portion of a larger property that the USACE issued a PJD for in 2016 (2016-00196N). The aquatic resources delineation report, field datasheets, and/or Geographic Information System Shapefiles were not available for review. Additionally, it appears the 2016 PJD map was not georeferenced, as when it was overlayed with the georeferenced aerial and property boundary, the mapped wetland feature did not correspond to the features visible on aerial imagery. Thus, the 2016 PJD was reviewed prior to conducting the site visit, but aquatic resources mapped within the Study Area were based on existing field conditions and data collected during the April 2021 survey. 354

4.0 RESULTS

4.1 Existing Site Conditions
The Study Area is made up of undeveloped lands comprised of annual grassland and riparian woodland/scrub. There is an abandoned gravel/asphalt access road along the eastern edge of the annual grassland, and numerous old dirt spoils piles are in the southern portion of the annual grassland; the dirt piles are overgrown with weedy non-native plants.

4.1.1 Regional Conditions
The Study Area is located on flat terrain in an area of rural residential and industrial/commercial development setting. The Study Area is situated at an elevational range of approximately 320 feet above mean sea level in the North Coast subregion of the Northwestern California region of the California IORULVWLFSURYLQFH

WKHDYHUDJHDQQXDOprecipitation is
approximately 43.13 inches (National Oceanic and Atmospheric Administration [NOAA] 2021a).

This aquatic resources delineation was conducted in spring, during the blooming season for many plant species. Most plants were identifiable to species based upon flowers, vegetative, and/or fruit morphology.

The survey was conducted at an appropriate time of the year to observe wetland hydrology. During the 2020-2021 water year leading up to the field survey date (October 1, 2020 to April 22, 2021), a total of

10.63 inches of precipitation was recorded at the Cloverdale 3.2 ESE, CA US reporting station (NOAA 2021b). The last recorded precipitation events for this region prior to the field survey was 0.39 inch between March 18 and March 19, 2021 (NOAA 2021b).

4.1.2 Vegetation Communities and Land Cover Types
There are two vegetation communities or land cover types onsite. Annual grassland makes up the upland and most of the roadside portions of the Study Area, and riparian woodland/scrub is found along the southwestern and southern boundary.

Annual Grassland
The annual grassland onsite is comprised of a variety of non-native weedy plants including wild oats (Avena fatua), foxtail barley (Hordeum murinum), Italian ryegrass (Festuca perennis), soft brome (Bromus hordeaceus), narrow-leaved plantain (Plantago lanceolata), and prickly lettuce (Lactuca serriola). Much of the grassland onsite appears to be historically disturbed by grading or leveling. The Study Area appears to have been graded around 2004 according to Google Earth photos. Dirt spoil piles are located in the annual grassland and have been overgrown with weedy vegetation.

Riparian Woodland/Scrub
The riparian woodland/scrub community onsite is located within and adjacent to the seasonal creek along the southern and southeastern portions of the Study Area. This community is dominated by Goodding’s black willow (Salix gooddingii), arroyo willow (Salix lasiolepis), a variety of other willow species (Salix sp.), 355

coast live oak (Quercus agrifolia), and Fremont’s cottonwood (Populus fremontii). The understory is scattered with open to dense areas of Himalayan blackberry (Rubus armeniacus), French broom (Genista monspessulana), poison oak (Toxicodendron diversilobum), and coyote brush (Baccharis pilularis).

4.1.3 California Aquatic Resource Inventory
The California Aquatic Resource Inventory (CARI; San Francisco Estuary Institute [SFEI] 2017) is a statewide map of surface waters and related habitats combining multiple national and regional datasets, including the National Wetlands Inventory and the National Hydrography Dataset. CARI includes aquatic resource features mapped using a variety of remote sensing and modeling techniques. As such, these aquatic features may or may not exist as represented. In addition, CARI data varies in detail, accuracy, and age, and is meant to be used as a tool to assist with an aquatic resource delineation but not as the only source of information (SFEI 2017).

There are no CARI waters mapped within the Study Area. A fluvial natural feature (Russian River) is mapped to the east of the Study Area and another fluvial natural feature (Cloverdale Creek) is mapped to the north of the Study Area (Figure 2. California Aquatic Resources Inventory).

4.1.4 Soils
According to the Web Soil Survey (NRCS 2021a), two soil units, or types, have been mapped within the Study Area (Figure 3. Natural Resources Conservation Service Soil Types):

JoG – Josephine loam, 50 to 75 percent slopes
PcB – Pajaro clay loam, overwash, 2 to 5 percent slopes Pcp – Pajaro clay loam, overwash, 2 to 5 percent is considered hydric and contains hydric components (NRCS 2021b) (Table 2).

4.2.1 Wetlands
Seasonal Wetland Swale
Seasonal wetland swales are generally linear wetland features that convey storm water runoff, but do not exhibit an OHWM, and support a predominance of hydrophytic vegetation. These are typically inundated for short periods during and immediately after rain events, but usually maintain soil saturation for longer periods mainly during the growing season. There is one seasonal wetland swale along the northern boundary of the Study Area, adjacent to the gravel road. Dominant species within the seasonal wetland swale included Italian ryegrass (FAC), pennyroyal (OBL; Mentha pulegium), curly dock (FAC; Rumex crispus), and spiny-fruit buttercup (FACW; Ranunculus muricatus).

Sample point 2 was taken in the seasonal wetland swale. The soil matrix color was 10YR4/2 with 10- percent redox concentrations colored 5YR 4/6. Soils were determined to be hydric based on the presence of field indicator depleted matrix (F3). Wetland hydrology indicators observed included water marks (B1) and biotic crust (B12).

4.2.2 Other Waters
Seasonal Creek
One seasonal creek flows along the southern boundary of the Study Area. The creek is deeply incised in portions with a sparsely vegetated bed composed primarily of cobbles and woody debris. The creek banks are highly vegetated with riparian vegetation such as Goodding’s willow, arroyo willow, Fremont’s cottonwood, Himalayan blackberry, and poison oak. OHWM Transect 7 was collected across the seasonal creek to document the OHWM. OHWM indicators observed included break in bank slope and change in vegetation cover. The boundary of aquatic resources within this area was delineated using the OHWM of the seasonal creek, consistent with the OHWM Guide (USACE 2008a). The riparian woodland above the OHWM was not mapped as an aquatic resource, as it was above the observed OHWM and hydrology indicators were not observed above the mapped OHWM. Vegetation above the OHWM transitioned from willow species (FACW) to Freemont’s cottonwood and oak species (N/L, assumed UPL). Because of the 360

lack of hydrology indicators and hydrophytic vegetation a wetland determination sample point was not collected within the riparian woodland above the OHWM.

Four upland points (sample points 3, 4, 5, and 6) were collected along the western boundary in a slight roadside depression, north of the mapped seasonal creek. The 2016 PJD appeared to have wetlands mapped within this area; however, sample points collected within this area did not demonstrate a dominance of hydrophytic vegetation, the presence of hydric soils, or wetland hydrology (Attachment B), and no OHWM indicators were observed. This area was mapped as uplands. While vegetation and hydrologic indicators may be adversely affected by drought conditions, as is the case for this region, it is highly unlikely that soils would be affected as such. No hydric soil indicators were found at sample points 3, 4, 5, and 6. Therefore, under normal precipitation conditions, it is unlikely this roadside area would support wetlands.

5.0 JURISDICTIONAL ASSESSMENT
The Russian River is designated as a navigable water. The seasonal creek mapped onsite appears to be hydrologically connected to the Russian River via culverts located offsite. Thus, the seasonal creek is likely an intermittent tributary to the Russian River. The seasonal wetland swale appears to receive hydrology from the property north of the Study Area and flows adjacent to the existing gravel road, without a direct surface water connection to the seasonal creek. The seasonal wetland swale does not appear to have a direct surface connection to the seasonal creek or another feature. The USACE will make the ultimate jurisdictional determination for the aquatic features mapped onsite.

6.0 CONCLUSION
A total of 0.180 acre of aquatic resources have been mapped within the Study Area. This acreage represents a calculated estimation of the extent of aquatic resources within the Study Area and do not imply jurisdiction; they are subject to modification following USACE review and/or the verification process.

The placement of dredged or fill material into jurisdictional features would require a permit pursuant to Section 404 of the CWA and certification or waiver in compliance with Section 401 of the CWA.

CALIFORNIA | FLORIDA | TEXAS
Corporate Office 4305 Hacienda Drive, Suite 550, Pleasanton, CA 94588 925.463.0611 www.TJKM.com 1 TECHNICAL MEMORANDUM
TJKM prepared a focused transportation analysis for the proposed residential development located at Asti Road and Railroad Avenue in Cloverdale, California. The following memorandum evaluates trip generation, on-site circulation and sight distance, and parking supply for the proposed project.

Currently, the project site is vacant. The project proposes to construct 62,442 square feet (s.f.) of 81 multifamily housing units and 1,130 s.f. of shared amenities, including a community area, community kitchen, laundry facility, and fitness room. Figure 1 shows the project site plan dated March 16, 2021.

VEHICLE MILES TRAVELED
TJKM evaluated the proposed multifamily residential development utilizing the Institute of Transportation Engineers (ITE) Trip Generation Manual, 10th edition. The trip generation is based on ITE rates for Multifamily Housing (LU 220).

The project is expected to generate a total of 593 daily weekday trips, with 38 (9 inbound, 29 outbound) trips during the a.m. peak hour and 46 (29 inbound, 17 outbound) trips during the p.m. peak hour.

Table 1 summarizes the expected trips generated by the proposed development.

As explained in the Office of Planning and Research’s 2018 Technical Advisory on Evaluating Transportation Impacts in CEQA (OPR VMT Advisory), “evidence supports the presumption of less than significant impact for a 100 percent affordable residential development … in infill locations.” (OPR VMT Advisory, p. 15.)
Furthermore, the nearest transit stop is located less than 0.5 mile away from the Project site at the corner of S. East Street and Lake Street.

4 ON-SITE CIRCULATION
TJKM reviewed internal and external access for the project site for delivery vehicles based on the proposed site plan (Figure 1). The proposed project will be accessed via two full-access driveways on Asti Road. The driveways provide project access to and from Asti Road, a two-lane roadway with a posted speed limit of 45 miles per hour (mph). The project driveways are located north of the Asti Road/Railroad Avenue intersection. There are single family residential uses around the project site, along with industrial uses located south of Railroad Avenue. Vehicles will enter the project site by turning right or left into the project driveway from Asti Road, and will exit by turning right or left onto Asti Road. Delivery vehicles will turn left or right into the project site from the north or south via Asti Road. Once inside the project site, the trucks will circulate around the project site via the internal roadway system, which forms a loop through the project site and connects to both project driveways.

Two proposed screened trash enclosures are located in the northern and southern portions of the project site. Garbage trucks will use the internal roadway to circulate to the two trash enclosures located in the northwest and southwest areas of the project site. The garbage trucks will likely enter the project site via the southern driveway, turning right to reach the southern trash enclosure, then following the loop to the northern trash enclosure and exiting via the northern driveway. Emergency vehicles may access the project site via both driveways and following the internal loop to access each building. A system of internal sidewalks, crosswalks and curb ramps provide a network for pedestrians to circulate through the development. The pedestrian network connects the residential buildings to each other and to the community amenities located in the center of the project site. Additionally, the pedestrian network connect residents to the accessible parking stalls through the project site. There are three bike storage lockers and five bike racks located in the project site. Bicyclists can access the project site via existing Class II bike lanes on Asti Road.

SIGHT DISTANCE
Sight distance is evaluated to determine if a driver will have adequate visibility to enter a roadway safely and without conflicts with existing traffic on the roadway. The project access point(s) should be free and clear of any obstructions that would materially and adversely affect the sight distance of exiting vehicles to and from oncoming vehicles, pedestrians, and cyclists. The project site plan proposes two access points withal movements permitted for motorists to enter and exit the project site. The driveways are located on the east side of Asti Road, north of the Asti Road/Railroad Avenue intersection. Sight distance evaluation at the driveway follows.

The Highway Design Manual (HDM), Chapter 200, 2018, requires a minimum stopping sight distance of 360 feet for a design speed of 45 mph (Asti Avenue). The lines of sight for vehicles exiting the proposed southern driveway on Asti Road and vehicles travelling southbound on Asti Road is clear and visible for at least 360 feet. The lines of sight for vehicles exiting the proposed southern driveway on Asti Road and vehicles travelling northbound on Asti Road is obstructed by trees and other greenery located on the east side of Asti Road, however, it is assumed these obstructions will be removed during construction. Based on preliminary analysis, the project provides adequate sight distance for vehicles entering and exiting the project site at the southern driveway. The lines of sight for vehicles exiting the proposed northern driveway on Asti Road and vehicles travelling northbound and southbound on Asti 405
5 Road is clear and visible for at least 360 feet. Based on preliminary analysis, the project provides adequate sight distance for vehicles entering and exiting the project site at the northern driveway.

PARKING DEMAND
This section discusses vehicle parking for the proposed project and includes an assessment of whether the proposed parking supply is adequate based on the proposed project size and zoning regulations.

Based on the project site plan (Figure 1), the project proposes to provide 119 automobile parking spaces, including 14 accessible parking spaces, and 50 bicycle parking spaces.

The City of Cloverdale Municipal Code requires one covered parking space plus 0.5 unrestricted shared parking places per studio unit, one covered parking space plus one unrestricted shared parking places per one bedroom unit, and one covered parking space and two unrestricted shared parking places per units with two or more bedrooms. The Code does not provide requirements for bicycle parking for residential land uses. To comply with the Cloverdale Municipal Code, the proposed project requires 213 parking spaces total, based on the project site plan, which proposes 30 one bedroom units and 51 units with two or more bedrooms. Additionally, to comply with the State Disables Access Regulations, the proposed project requires seven accessible parking spaces. The proposed project meets the requirements for accessible parking, but does not satisfy the City of Cloverdale parking requirements for automobiles. In order to meet the parking requirements for the City of Cloverdale, the project must provide 94 additional automobile parking spaces.

PEDESTRIAN, BICYCLE, AND TRANSIT IMPACTS
Pedestrian Access
An impact to pedestrians occurs if the proposed project disrupts existing pedestrian’s facilities; or create inconsistencies with planned pedestrian facilities or adopted pedestrian system plans, guidelines, policies, or standards. Pedestrian facilities do not exist near the project site, thus the proposed project does not conflict with existing and planned pedestrian facilities; therefore, the impact to pedestrian facilities is less-than-significant.

Bicycle Access
An impact to bicyclists occurs if the proposed project disrupts existing bicycle facilities; or conflicts or creates inconsistencies with adopted bicycle system plans, guidelines, policies or standards within the City of Cloverdale. The project is expected to generate few additional bicycle trips on existing and planned bicycle facilities. The additional bicycle trips will be supported by existing Class II bike lanes on Asti Road and a Class I pathway along the west side of Asti Road, proposed by the Countywide Bicycle and Pedestrian Master Plan (Sonoma County Transportation Authority, 2014). Assuming the proposed project conform to the existing and proposed bike facilities on Asti Road, the impact to bicycle facilities is less-than-significant.
406
6 Transit Access
A proposed project is considered to have a significant impact on transit if it conflicts with existing or planned transit facilities, or is expected to generate additional transit trips and does not provide adequate facilities for pedestrians and bicyclists to access transit routes and stops. There are no transit stops in the immediate vicinity of the project site. Therefore, impacts to transit service are expected to be less-than-significant.

CONCLUSION
Pursuant to CEQA, the proposed project’s VMT impacts is less than significant. Based on preliminary analyses, the proposed site plan supports on-site circulation of vehicles, delivery trucks, garbage trucks, emergency vehicles and pedestrians. Additionally, both project driveways are free from sight distance obstructions. The proposed project is expected to have less-than-significant impacts to existing and proposed pedestrian, bicycle and transit facilities.

GENERAL NOTES
1: Soil classifications are based on the Unified Soil Classification System (USCS). Descriptions and stratum lines are interpretive, and actual lithologic changes may be gradual. Field descriptions may have been modified to reflect results of lab tests. 2: Descriptions on these logs apply only at the specific boring locations and at the time the borings were advanced. They are not warranted to be representative of subsurface conditions at other locations or times.
