This Biological Resources Assessment (BRA) has been prepared by FirstCarbon Solutions (FCS) at the request of the City of Cloverdale (client) for the proposed Soda Springs Ranch Open Space Preserve (proposed project). The purpose of the BRA is to (1) document existing and potentially occurring biological resources on the project site and adjacent areas; (2) analyze potential projectrelated impacts on regulated biological resources; (3) summarize relevant local, State, and federal regulations; and (4) recommend appropriate measures to mitigate potential impacts on biological resources.

1.1 - Project Location
The project site is located immediately west and north of the City of Cloverdale in Sonoma County, California (Exhibit 1). It is within the Porterfield Creek Watershed and is surrounded by open space to the north, south, and west and by residential development to the east. The 208.72-acre project site consists of Assessor’s Parcel Numbers (APNs) 115-220-006, 115-220-007, and 115-220-019.

The project site is directly outside and adjacent to the Cloverdale city limits but within the City’s Sphere of Influence (SOI) and Urban Growth Boundary.
1 The City’s SOI is the area of the City
designated for future annexation, which would require approval from the Sonoma County Local Agency Formation Commission (LAFCo). The City of Cloverdale General Plan (General Plan) designates the entirety of the project site as Conservation Feature (CF). The purpose of the CF land use designation is to manage and preserve valuable biological, visual, and agricultural resources in the Cloverdale Planning Area.2
The project site is located within an Open Space Preserve zoned for natural resource conservation and very low-density residential development. It is currently and has historically been used for open space, recreational, grazing, hunting, and equipment storage purposes. The project site lies north of West Cherry Creek Road, which extends east via South Cloverdale Boulevard to the United States Highway 101 (US-101; Redwood Highway). Specifically, the project site is located on the Cloverdale, California United States Geological Survey (USGS) 7.5-minute Topographical Quadrangle Map, Township 11 North, Range 11 West, Section 13 Mt. Diablo Base and Meridian (approximately Latitude 38° North 0’ 38.78” and Longitude -123° West 0’ -123.03”).

Areas surrounding the project site consist of a mixture of low-density residential, public institutional, and undeveloped lands (Exhibit 2). Bordering the project site to the east are single-family homes. To 1 Permit Sonoma. 2025. City of Cloverdale. Website:

To the north are undeveloped lands composed of oak woodland and forest habitat. US101 lies approximately 1.10 miles east of the project site.

1.2 - Project Description
The proposed project is an Open Space Preserve, located at 600 Cherry Creek Road (APN 115-220- 007, -006, and -019). The proposed project would establish a conservation easement over the site, resulting in the closure of unnecessary trails, the repair of existing roads, the development of multiuse trails, and additional proposed improvements, as further described below.

1.2.1 - Annexation into the City
The proposed project is located in an unincorporated area of Sonoma County, immediately west of the City of Cloverdale. The proposed project would include annexation of the entire project site into the City. The project site would be pre-zoned as Conservation.

1.2.2 - Trail/Road Closures, Demolition, and Removal
The proposed project would result in the closure of existing roads, which are also used as hiking trails, resulting in the closure of approximately 0.90 mile of existing trails/roads and the removal of associated signage, fencing, and equipment. The proposed project would also involve the demolition of several on-site structures, including an open-walled shed, a trailer adjacent to the West Second Street access gate at the eastern edge of the site, a culvert on the southeastern corner of the site, and a culvert in the eastern portion of the site. The proposed project would include vegetation removal (including brush clearance) as needed, consistent with annual maintenance for fire safety.

1.2.3 - Land Uses
The proposed project would include the development of three new multiuse trails, resulting in the development of approximately 0.94 mile of new trail, as well as the development of 11 new picnic sites and a new 2,000-square-foot parking site (Exhibit 3). The project applicant would also incorporate site-specific improvements, including the installation of new fencing, signage, and buffer areas alongside site boundaries and sensitive habitat areas.

The proposed project would include the installation of signs, trees, and scattered vegetation to discourage the usage of the closed trails. As part of the 208.66-acre conservation easement that would cover the entirety of the site, the proposed project would preserve existing open space adjacent to the proposed improvements; these areas would not contain any new trails or facilities.

The proposed project would also include coordination with the Northern Sonoma County Fire Department to maintain an existing shaded fuel break between the conservation space and the residences along Port Circle. The proposed project components are summarized in Table 1. 317

Sources: Hollis Agricultural Consulting. 2023.

Circulation
Access to the project site is currently provided by a gated dirt road at the western terminus of West Second Street. The proposed project would implement accessibility improvements, including curbside improvements and signage as well as repair improvements to existing roads within the project site.

Eight underutilized trails would be closed and three new trails for bike and pedestrian use would be created. An additional access point to the site, along its eastern flank, would be incorporated at Foothill Boulevard, and proposed curbside improvements and right-of-way improvements, including signage and fencing, would increase visibility (Exhibit 3).

Parking
The proposed project would include a total of up to seven open-air parking spaces within the approximately 2,000-square-foot proposed parking area (Exhibit 3). These would be located adjacent to the Preserve’s entrance on West Second Street and Foothill Boulevard.

Open Space and Recreational Facilities
The proposed project would preserve a total of 208.66 acres of open space, including oak woodland, chaparral, grasslands, fir forest, redwood groves, and riparian vegetation surrounding creeks. This would include preservation of key riparian corridors and landmark features, including the North Branch of Porterfield Creek, a General Plan-designated Priority Riparian Corridor, and Soda Springs, a natural soda water spring along the site’s northern boundary. Upon installation of new picnic areas and multiuse trails, as shown on Exhibit 3, the site would incorporate necessary setbacks along site boundaries and maintain an existing shaded fuel break along the site’s southeastern boundary near Port Circle.

Utilities
Proposed modifications to the existing on-site storm drainage system would consist of culverts, inlets, and basins to detain waters on-site and provide natural filtration and pre-treatment. 318

Electricity and natural gas would continue to be provided by Pacific Gas and Electric Company (PG&E), which provides electricity and natural gas to the City of Cloverdale. 3 Sonoma
Clean Power would provide any electric generation service to the on-site parking area lighting, while PG&E would deliver electricity through the existing grid.4 Demolition and Construction Activities
The proposed project would include the demolition of an open-sided shed and trailer, the removal and replacement of two culverts, widening of the West Second Street access entry area to accommodate fire trucks, construction of a parking area including Americans with Disabilities Act (ADA) spaces, and the construction of new trails. Construction equipment would include a box grader and excavator.

Demolition and construction activities are anticipated to begin as soon as all permits and mitigation activities allow and would have a duration of approximately 3 months. 3 City of Cloverdale. 2008. General Plan Update Draft EIR. Website: https://www.cloverdale.net/243/Long-Range-Planning.

2.1 - Federal

2.1.1 - Endangered Species Act
The United States Fish and Wildlife Service (USFWS) has jurisdiction over species listed as threatened or endangered under the Endangered Species Act. Section 9 of the Endangered Species Act protects listed species from “take,” which is broadly defined as actions taken to “harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or attempt to engage in any such conduct.” The Endangered Species Act protects threatened and endangered plants and animals and their critical habitat. Candidate species are those proposed for listing; these species are usually treated by resource agencies as if they were listed during the environmental review process.

A proposed project may acquire permission to take listed and candidate species through implementation of sections of the Endangered Species Act. If the proposed project is funded by, authorized by, or otherwise involves a federal agency, Section 7 requires those agencies to consult with the USFWS to ensure that the project does not jeopardize the future existence of any listed species. The consultation results in either a concurrence letter from USFWS stating that the proposed action does not jeopardize the species or a Biological Opinion issued by USFWS that includes a defined limit of “take” of listed species that is authorized for the action. When there is no federal nexus to pursue Section 7 permissions, USFWS may authorize take of listed species through Section 10, which allows private landowners, corporations, Native American Tribes, states, cities, and counties to implement projects that could affect listed species. Under this process, the project proponent seeks take permissions through completing and submitting a Habitat Conservation Plan (HCP) for approval by the USFWS. The HCP defines the project and potential for take of species and outlines measures to mitigate or compensate for impacts that would occur during implementation of the project. Often a draft Implementing Agreement (IA) is included with the permit application for larger HCPs, such as a regional plan. An IA is a contract that describes the roles and responsibilities of the permit holder, the federal wildlife agency, and any other parties responsible for implementing the HCP.

2.1.2 - Migratory Bird Treaty Act
Raptors (birds of prey), migratory birds, and other avian species are protected by several State and federal laws. The Migratory Bird Treaty Act (MBTA) implements international treaties between the United States and other nations devised to protect migratory birds, 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. The MBTA prohibits the killing, possessing, or trading of migratory birds except in accordance with regulations prescribed by the Secretary of the Interior. All 326

2.1.3 - Bald and Golden Eagle Protection Act
The golden eagle (Aquila chrysaetos) and bald eagle (Haliaeetus leucocephalus) are afforded additional protection under the Eagle Protection Act, amended in 1973 (16 USC § 669, et seq.) and the Bald and Golden Eagle Protection Act (16 USC §§ 668–668d).

2.1.4 - Clean Water Act
Section 404
The agencies are in receipt of the U.S. Supreme Court’s May 25, 2023, decision in the case of Sackett v. Environmental Protection Agency. In light of this decision, the agencies will interpret the phrase “waters of the United States” consistent with the Supreme Court’s decision in the Sackett case. In Sackett, the Supreme Court adopted the Rapanos plurality’s test for adjacent wetlands: only those wetlands with a continuous surface connection to other regulated waters, such that the two are indistinguishable.

The United States Army Corps of Engineers (USACE) administers Section 404 of the federal Clean Water Act (CWA), which regulates the discharge of dredge and fill material into waters of the United States. The term “waters of the United States” is defined in USACE regulations at 33 Code of Federal Regulations Part 328.3(a) as:

1. Waters which are:
a. Currently used, or were used in the past, or may be susceptible to use in interstate or foreign commerce, including all waters which are subject to the ebb and flow of the tide; b. The territorial seas; or
c. Interstate waters;

2. Impoundments of waters otherwise defined as waters of the United States under this definition, other than impoundments of waters identified under paragraph (a)(5) of this section;

3. Tributaries of waters identified in paragraphs (a)(1) or (2) of this section that are relatively permanent, standing or continuously flowing bodies of water;

4. Wetlands adjacent to the following waters:
a. Waters identified in paragraph (a)(1) of this section; or b. Relatively permanent, standing or continuously flowing bodies of water identified in paragraph (a)(2) or (a)(3) of this section and with a continuous surface connection to those waters;

5. Intrastate lakes and ponds not identified in paragraphs (a)(1) through (4) of this section that are relatively permanent, standing or continuously flowing bodies of water with a continuous surface connection to the waters identified in paragraph (a)(1) or (a)(3) of this section. 327

1. Waste treatment systems, including treatment ponds or lagoons, designed to meet the requirements of the Clean Water Act;

2. Prior converted cropland designated by the Secretary of Agriculture. The exclusion would cease upon a change of use, which means that the area is no longer available for the production of agricultural commodities. Notwithstanding the determination of an area's status as prior converted cropland by any other federal agency, for the purposes of the Clean Water Act, the final authority regarding Clean Water Act jurisdiction remains with the United States Environmental Protection Agency (EPA);

3. Ditches (including roadside ditches) excavated wholly in and draining only dry land and that do not carry a relatively permanent flow of water;

4. Artificially irrigated areas that would revert to dry land if the irrigation ceased;

5. Artificial lakes or ponds created by excavating or diking dry land to collect and retain water and which are used exclusively for such purposes as stock watering, irrigation, settling basins, or rice growing;

6. Artificial reflecting or swimming pools or other small ornamental bodies of water created by excavating or diking dry land to retain water for primarily aesthetic reasons;

7. Waterfilled depressions created in dry land incidental to construction activity and pits excavated in dry land for the purpose of obtaining fill, sand, or gravel unless and until the construction or excavation operation is abandoned and the resulting body of water meets the definition of waters of the United States; and

8. Swales and erosional features (e.g., gullies, small washes) characterized by low volume, infrequent, or short duration flow.

Waters of the United States do not include prior converted cropland. Notwithstanding the determination of an area’s status as prior converted cropland by any other federal agency, for the purposes of the CWA, the final authority regarding CWA jurisdiction remains with the EPA and/or USACE.
“Wetland” refers to 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. Wetlands generally include swamps, marshes, bogs, and seasonal wetlands. Wetlands are considered jurisdictional if they fall under one of the categories of waters of the United States defined above. The USACE jurisdiction typically extends up to the ordinary high water mark (OHWM).

In general, a USACE permit must be obtained before placing fill in wetlands or other waters of the United States. The type of permit depends on the impacted acreage, the purpose of the proposed fill, and other factors.

Section 401 of the CWA states that “any applicant for a federal permit for activities that involve a discharge to waters of the State, shall provide the federal permitting agency a certification from the State in which the discharge is proposed that states that the discharge will comply with the applicable provisions under the federal Clean Water Act.” Therefore, before the USACE will issue a Section 404 permit, applicants must apply for and receive a Section 401 Water Quality Certification from the Regional Water Quality Control Board (RWQCB).

2.2 - State

2.2.1 - CEQA Guidelines
The California Environmental Quality Act (CEQA) requires public agencies to evaluate potential impacts to special-status species and their habitat. The following CEQA Guidelines Appendix G checklist questions serve as thresholds of significance when evaluating the potential impacts of a proposed project on biological resources. Impacts are considered significant if a project would:
• Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as being a candidate, sensitive, or special-status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Wildlife (CDFW) or USFWS. • Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, or regulations, or by the CDFW or USFWS. • Have a substantial adverse effect on federally and State protected wetlands as defined by Section 404 of the Clean Water Act (including but not limited to marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means. • 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.
• Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance.
• Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or State Habitat Conservation Plan.

Oak Woodlands Conservation Act
California Senate Bill (SB) 1334, the Oak Woodlands Conservation Act, became law on January 1, 2005, and was added to the CEQA statutes as Section 21083.4. This statute requires that a county must determine whether or not a project will result in a significant impact on oak woodlands and, if it is determined that a project may result in a significant impact on oak woodlands then the county shall require one or more of the following mitigation measures:

• Contribute funds to the Oak Woodlands Conservation Fund for the purpose of purchasing oak woodlands conservation easements;
• Other mitigation measures developed by the county.

2.2.2 - California Endangered Species Act
The State of California enacted the California Endangered Species Act (CESA) in 1984. CESA is similar to the Endangered Species Act but pertains to State-listed endangered and threatened species. CESA requires State agencies to consult with the CDFW when preparing CEQA documents to ensure that the State lead agency actions do not jeopardize the continued existence of a listed species or result in the destruction or adverse modification of habitat essential to the continued existence of those species if there are reasonable and prudent alternatives available (Fish and Game Code [FGC] § 2080). CESA directs agencies to consult with the CDFW on projects or actions that could affect listed species, directs the CDFW to determine whether jeopardy would occur, and allows the CDFW to identify “reasonable and prudent alternatives” to the project consistent with conserving the species. CESA allows the CDFW to authorize exceptions to the State’s prohibition against take of a listed species if the take is incidental to carrying out an otherwise lawful project that has been approved under CEQA (FGC § 2081).

2.2.3 - California Fish and Game Code
Rare, Threated, and Endangered Species
Under CESA, the CDFW has the responsibility for maintaining a list of endangered and threatened species (FGC § 2070). Fish and Game Code Sections 2050 through 2098 outline the protection provided to California’s rare, endangered, and threatened species. Fish and Game Code Section 2080 prohibits the taking of plants and animals listed under the CESA, and Fish and Game Code Section 2081 established an incidental take permit program for State-listed species. The CDFW maintains a list of “candidate species” which it formally notices as being under review in addition to the list of endangered or threatened species.

Fully Protected Species
Fish and Game Code Section 1913 exempts from take prohibition “the removal of endangered or rare native plants from a canal, lateral ditch, building site, or road, or other right-of-way.” Project impacts to these species are not considered significant unless the species are known to have a high potential to occur within the area of disturbance associated with construction of the proposed project. Fish and Game Code Sections 3500–5500 outline protection for fully protected species of mammals, birds, reptiles, amphibians, and fish. Species that are fully protected by these sections may not be taken or possessed at any time. The CDFW cannot issue permits or licenses that authorize the take of any 330

Species of Special Concern
In addition to formal listing under the Endangered Species Act and CESA, some species receive additional consideration by the CDFW and local lead agencies during the CEQA process. Species that may be considered for review are those listed as a “Species of Special Concern.” The CDFW maintains lists of “Species of Special Concern” that serve as species “watch lists.” Species with this status may have limited distributions or limited populations and/or the extent of their habitats has been reduced substantially, such that their populations may be threatened. Thus, their populations are monitored, and they may receive special attention during environmental review. While they do not have statutory protection, they may be considered rare under CEQA and specific protection measures may be warranted. In addition to Species of Special Concern, the CDFW Special Animals List identifies animals that are tracked by the California Natural Diversity Database (CNDDB) and may be potentially vulnerable but warrant no federal interest and no legal protection.

Other Sensitive Species
Sensitive species that would qualify for listing but are not currently listed are afforded protection under CEQA. CEQA Guidelines Section 15065 (Mandatory Findings of Significance) requires that a substantial reduction in numbers of a rare or endangered species be considered a significant effect.

CEQA Guidelines Section 15380 (Rare or Endangered Species) provides for the assessment of unlisted species as rare or endangered under CEQA if the species can be shown to meet the criteria for listing. Unlisted plant species on the California Native Plant Society (CNPS) List ranked 1A, 1B, 2A, and 2B would typically require evaluation under CEQA.

Native Bird Protection
Fish and Game Code Sections 3503, 3503.5, and 3513 protect native birds. Under Section 3503, it is unlawful to take, possess, or needlessly destroy the nest or eggs of any native bird. Under Fish and Game Code Section 3503.5, it is unlawful to take, possess, or destroy any birds in the orders of Falconiformes or Strigiformes (birds of prey) or to take, possess, or destroy the nest or eggs of any such bird. Under Fish and Game Code Section 3513, it is unlawful to take or possess any native, migratory bird as designated in the MBTA except as provided by rules and provisions of the MBTA.

Mitigation for avoidance of impacts to nesting birds is typically included in CEQA and other permitting documents to ensure project compliance with these Fish and Game Code Sections.

Native Plant Protection Act
The Native Plant Protection Act of 1977 (NPPA) (FGC § 1900, et seq.) prohibits the taking, possessing, or sale within the State of any plants with a State designation of rare, threatened, or endangered (as defined by the CDFW). An exception to this prohibition in the NPPA allows landowners to take listed plant species under specified circumstances, provided that the owners first notify CDFW and give the agency at least 10 days to come and retrieve (and presumably replant) the 331

Fish and Game Code Section 1913 exempts from take prohibition “the removal of endangered or rare native plants from a canal, lateral ditch, building site, or road, or other right-of-way.” Project impacts to these species are not considered significant unless the species are known to have a high potential to occur within the area of disturbance associated with construction of the proposed project.

2.2.4 - California Porter-Cologne Water Quality Control Act The RWQCB regulates actions that would involve “discharging waste, or proposing to discharge waste, within any region that could affect the water of the State” (Water Code § 13260(a)), pursuant to provisions of the Porter-Cologne Water Quality Act. “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)). In 2019, the California State Water Resources Control Board (State Water Board) published the State Wetland Definition and Procedures for Discharges of Dredged or Fill Material to Waters of the State (Procedures) to guide wetland/waters of the State determinations and the permitting process.5

2.2.5 - California State Water Resources Control Board/RWQCB Stormwater Management Permitting
While federal CWA National Pollutant Discharge Elimination System (NPDES) regulations allow two permitting options for construction-related stormwater discharges (individual permits and General Permits), the State Water Board has elected to adopt only one Statewide Construction General Permit at this time that will apply to all stormwater discharges associated with construction activity, except those located on Tribal lands in the Lake Tahoe Hydrologic Unit and those performed by the California Department of Transportation (Caltrans).

The Construction General Permit requires all dischargers where construction activity disturbs greater than 1 acre of land or those sites less than 1 acre that are part of a common plan of development or sale that disturbs more than one acre of land surface to:

1. Develop and implement a Storm Water Pollution Prevention Plan (SWPPP) which specifies Best Management Practices (BMPs) that will prevent all construction pollutants from contacting stormwater with the intent of keeping all products of erosion from moving off-site into receiving waters.

2. Eliminate or reduce non-stormwater discharges to storm sewer systems and other waters of the nation. Achieve quantitatively defined (i.e., numeric) pollutant-specific discharge standards, and conduct much more rigorous monitoring based on the project’s projected risk level.

2.2.6 - Sensitive Natural Community Rankings
The CDFW maintains sensitivity rankings of natural vegetation communities in the California Sensitive Natural Communities list.1 CDFW evaluates natural communities using the NatureServe Heritage Methodology and ranking system that indicates conservation status of communities, accordingly:2
• Rank S1–Critically Imperiled: At very high risk of extirpation in the jurisdiction due to very restricted range, very few populations or occurrences, very steep declines, severe threats, or other factors.
• Rank S2–Imperiled: At high risk of extirpation in the jurisdiction due to restricted range, few populations or occurrences, steep declines, severe threats, or other factors. • Rank S3–Vulnerable: At moderate risk of extirpation in the jurisdiction due to a fairly restricted range, relatively few populations or occurrences, recent and widespread declines, threats, or other factors.
• Rank S4–Apparently Secure: At a fairly low risk of extirpation in the jurisdiction due to an extensive range and/or many populations or occurrences, but with possible cause for some concern as a result of local recent declines, threats, or other factors. • Rank S5–Secure: At very low or no risk of extirpation in the jurisdiction due to a very extensive range, abundant populations or occurrences, with little to no concern from declines or threats.

Per the CDFW, natural communities ranked S1–S3 are considered Sensitive Natural Communities to be addressed during CEQA review or other environmental review. Not all the natural communities listed on the 2023 CDFW California Natural Community List are ranked, however all sensitive natural communities are indicated by a “Y” in the Sensitive column, while those that are not considered sensitive are indicated by an “N” in the Sensitive column. Thus, potential impacts to communities ranked S1-S3 and/or marked “Y” in the Sensitive column on the Sensitive Natural Communities list should be analyzed during the preparation of environmental documents pursuant to CEQA as they may meet the definition of Rare or Endangered under the CEQA Guidelines Section 15380 criteria.

The CNDDB maintains listings of sensitive communities in the database that were entered in the mid1990s using a previous classification system. CDFW recommends that these “Legacy Sensitive Natural Communities” be classified using the current Manual of California Vegetation (MCV) system and that they be addressed in the environmental review process under the new classification and current sensitivity rankings.

2.2.7 - California Native Plant Society Rare Plant Rankings The CNPS maintains a rank of plant species that are native to California and that have low population numbers, limited distribution, or are otherwise threatened with extinction. This information is 333

• Rank 1A: Plants presumed extirpated in California and either rare or extinct elsewhere • Rank 1B: Plants rare, threatened, or endangered in California and elsewhere • Rank 2A: Plants presumed extirpated in California but common elsewhere • Rank 2B: Plants rare, threatened, or endangered in California but more common elsewhere • Rank 3: Plants about which more information is needed • Rank 4: Watch List: Plants of limited distribution
Potential impacts to populations of CNPS ranked plants receive consideration under CEQA review. All plants appearing on the CNPS List ranked 1 or 2 are considered to meet CEQA Guidelines Section 15380 criteria. Rank 3 and 4 plants do not automatically meet this definition. Rank 4 plants do not clearly meet CEQA standards and thresholds for impact considerations. Nevertheless, some level of CEQA review is justified for California Rare Plant Rank (CRPR) 4 taxa, and under some circumstances, a full impact analysis is warranted. Taxa that can be shown to meet the criteria for endangered, rare, or threatened status under CEQA Guidelines Section 15380(d) or that can be shown to be regionally rare or unique as defined in CEQA Guidelines Section 15125(c) must be fully analyzed in a CEQA document. Some circumstances, such as local rarity, having occurrences peripheral to the taxon’s distribution, or having occurrences on unusual substrates or rare and declining habitats, provide justification for treating some CRPR 4 taxa occurrences as regionally rare or unique.

Preservation of individual trees or features rather than the larger habitat does not satisfy this policy.

Policy CDO 6-3 Large or otherwise significant trees shall be maintained both in residential, nonresidential, and open space areas by: (1) Revising development plans that would remove significant trees so that those trees are saved. (2) Developing standard conditions of approval to minimize damage during construction and provisions to assure that building foundations, utilities, walkways, irrigation, or use patterns will not damage root structures, trunks or crowns.

Policy CDO 6-4 New private and public development, including public street, sidewalk, utility, and park construction, shall provide a mix of trees with a crown that can provide shade and summer cooling and trees with height to create a silhouette against the skyline.

Policy CDO 6-5 New public and private development shall provide street trees parallel to streets— in planter strips, in sidewalks, or at back of sidewalks, spaced at regular intervals along the street. Tree intervals shall provide a canopy with leaves touching at maturity. Tree locations shall be identified prior to design of utilities, drainage, hydrants, electrical equipment boxes, vaults, etc., and those features should be subservient to tree locations.

Policy CDO 7-1 Conserve and protect the area's natural vegetation by: (1) Ensuring that drainage and runoff from City sources is not impairing the water quality of the Russian River. (2) Retaining existing riparian vegetation within the conservation buffers along all natural watercourses to preserve riparian vegetation and habitat. (3) Restoring degraded riparian habitats where feasible. (4) Prohibiting agricultural activities within the conservation buffers along all natural watercourses. (5) Avoiding the contamination of groundwater supplies.

2.3.2 - City of Cloverdale Municipal Code
The City has implemented Municipal Code Chapter 18.17–Tree Preservation (Tree Ordinance) to establish standards and programs to protect, preserve, and maintain groves and stands of mature trees and specified individual protected trees through discretionary permits.

Chapter 18.17–Tree Preservation
The City defines a protected trees any tree following tree species with a diameter at breast height (DBH) of 24 inches or greater: native oaks (Quercus sp.) including, but not limited to, black oak, valley oak, blue oak, interior live oak, coast live oak, Oracle oak (Quercus x morehus), and Oregon oak; American sycamore (Platanus occidentalis); California bay (Umbellularia californica), Douglas fir (Pseudotsuga menziesii), Ponderosa pine (Pinus ponderosa), Black walnut (Juglans nigra), and English walnut (Juglans regia). The City also considers California or coast redwood (Sequoia sp.) 335

Multi-trunk trees must possess at least one trunk with the stated DBH above to be considered a protected tree. All trees designated as a heritage tree or located within a riparian corridor, public right-of-way, or mitigation plantings are considered protected trees.

The City prohibits the removal of or damage to protected trees without a tree removal permit. Tree removal permit applications require an arborist report, identifying all protected trees on-site and which are proposed for removal. A landscape plan must depict the location of all in-kind replacement tree plantings and/or proof of in lieu fee payment. Some tree removals may be exempt from the City’s Tree Ordinance in emergency situations. If the City determines that a protected tree poses an imminent threat to the public safety or general welfare, or to private property or persons, or is deemed a fire hazard, it is exempt from the Tree Ordinance.

If tree(s) are proposed for removal, applicants must adhere to the City’s mitigation and tree replacement requirements, including, but not limited to, the replacement ratio for any removed trees, whether replacement should be on-site or through the payment of an in lieu fee, and the types of trees which may be planted as replacement trees, as determined by the planning commission or City council. Tree replacement ratios are required as follows in relation to the trees permitted to be removed:
• All protected trees permitted to be removed which have been determined by a qualified Arborist to be in excellent or good health and/or with moderate to good structure shall be replaced on a one-to-one trunk diameter basis.
• All protected trees permitted to be removed which have been determined by a qualified Arborist to have moderate or marginal health and/or with marginal structure shall be replaced on a twoto-one trunk diameter basis. • All protected trees permitted to be removed and determined by a qualified Arborist to have poor health or poor structure shall not be required to be replaced.

The Tree Ordinance states that the design of every development project shall preserve trees to the greatest extent possible. The design of proposed development shall address preservation of the most desirable and significant of the healthy trees and developers are encouraged to utilize creative land planning techniques to achieve this goal. All applicants for a development project shall include a tree preservation plan, including the following items: (1) a tree inventory with tree locations, size (trunk DBH), health, and species; (2) identification of all protected trees; (3) proposed locations of all new trees to be planted; (4) existing vegetation and proposed landscape plans; (5) location of trees to be removed; and (6) preservation measures.

All developments must adhere to the City’s guidelines to protect trees during construction activities, including, but not limited to: (1) Protective barriers must be placed around all newly planted and mature trees on-site; (2) All personnel must remain outside the established Environmental Sensitive Area (ESA); (3) No grading may occur within the tree ESAs; (4) No signage or other attachments can be fixed to trees; (5) Any required work within the tree ESAs may only be completed using hand tools; (6) Harmful liquids must remain away from the tree; and (7) No equipment, solvents, paint, asphalt, or debris of any kind shall be placed, stored, or allowed within the ESAs. 336

3.1 - Literature and Database Reviews
FCS conducted a literature review to evaluate potential project impacts on biological resources on the project site and in the surrounding area.

3.1.1 - Existing Documentation
As part of the literature review, an FCS Biologist compiled and analyzed existing environmental documentation for the project site. This included a nine-quadrangle search, as further described in Section 3.1.4 below. This documentation included literature pertaining to the habitat requirements of special-status species with the potential to occur in the project site and project vicinity; and federal register listings, protocols, and species data provided by the USFWS, CDFW, and CNPS. Additional existing documentation included previous technical studies as outlined below:
• Conservation Easement Baseline Documentation, Soda Springs Ranch Open Space Preserve, Hollis Agricultural Consulting (2023)

3.1.2 - Topographic Maps and Aerial Photographs
An FCS Biologist reviewed current USGS 7.5-minute topographic quadrangle map(s) and aerial photographs as a preliminary analysis of the existing conditions within the project site and immediate vicinity.7 Information obtained from the topographic maps included elevation, general watershed information, and potential drainage feature locations using Google Earth in conjunction with the EPA Watershed Assessment, Tracking, and Environmental Results System (WATERS).8 Aerial photographs provided a perspective of the current site conditions relative to on-site and off-site land use, plant community locations, and potential locations of wildlife movement corridors. To assess changes in site conditions over time, FCS Biologists reviewed historical aerial imagery maintained in Google Earth9 and assessed how these changes affected biological resources on-site. 7 United States Geological Survey (USGS). 2025.

3.1.3 - Soils
The United States Department of Agriculture (USDA) has published soil surveys that describe the soil series (i.e., group of soils with similar profiles) occurring within a particular area.10 These profiles include major horizons with similar thickness, arrangement, and other important characteristics.

These series are further subdivided into soil mapping units that provide specific information regarding soil characteristics. Many special-status plant species have a limited distribution based exclusively on soil type. Therefore, pertinent USDA soil survey maps were reviewed to determine the existing soil mapping units within the project site and to inform whether the soil conditions on-site are potentially suitable for any special-status plant species. However, Natural Resources Conservation Service (NRCS) soil maps utilize an approximately 1.4-acre minimum mapping unit, and line placement may not be accurate on a large (i.e., parcel-level) scale.

3.1.4 - Special-status Species Database Search
An FCS Biologist compiled a list of threatened, endangered, and otherwise special-status plant species previously recorded within the project vicinity based on a search of the USFWS Information for Planning and Consultation (IPaC) database,
11 the CNDDB,12 and the CNPS Inventory13 for the
Cloverdale, California USGS 7.5-minute Topographic Quadrangle Map and the eight surrounding quadrangles (Appendix A). The CNDDB Biogeographic Information and Observation System (BIOS 6) was used to determine the distance between the known occurrences of special-status plant species or populations and the project site.
14 3.1.5 - Trees
Biologists reviewed applicable State and local ordinances pertaining to tree preservation and protective measures and their tree replacement conditions or permits required.

3.1.6 - Jurisdictional Waters and Wetlands
FCS Biologists reviewed USGS topographic maps and aerial photography to identify any potential natural drainage features and water bodies. In general, all surface drainage features identified as blue-line streams on USGS maps and associated riparian habitat are considered potentially subject to State and federal regulatory authority as “waters of the United States and/or State.” 10 United States Department of Agriculture (USDA).

3.1.7 - Wildlife Movement Corridors and Nursery Sites
Wildlife movement corridors link areas of suitable wildlife habitat that are otherwise separated by natural and anthropogenic dispersal barriers, including rugged terrain, changes in vegetation, development, or human disturbance. Urbanization and the resulting fragmentation of open space areas create isolated “islands” of wildlife habitat, forming separated populations. Corridors act as an effective link between populations.

The project site was evaluated for evidence of wildlife movement corridors and nursery sites during the reconnaissance-level survey and review of aerial photographs. The focus of this study was to determine whether a change in land use at the project site could have significant impacts on the regional movement of wildlife. Conclusions are based on the information compiled during the literature review, including the aerial photographs, USGS topographic maps, and resource maps for the vicinity; the field survey; and professional experience with the desired topography, habitat, and resource requirements of the special-status species potentially utilizing the project site and vicinity.

3.2 - Field Survey

3.2.1 - Survey Personnel
FCS Biologists Juliet Simpson and Hannah Carney and FCS Geographic Information Systems (GIS) Analyst Sebastian Macias conducted a general wildlife, habitat, vegetation community, and aquatic resource survey on May 15 and May 16, 2025. The objective of the field survey was to ascertain general site conditions and wildlife use and to identify whether existing vegetation communities provide suitable habitat for special-status plant or wildlife species. Potentially sensitive areas identified during the literature review were ground-truthed during the field surveys for mapping accuracy. Special attention was paid to sensitive habitats and areas potentially supporting specialstatus floral and faunal species. Project site photographs taken during the field survey can be found in Appendix C.

Wildlife species detected during the reconnaissance-level surveys by sight, calls, tracks, scat, or other signs were recorded. Notations were made regarding suitable habitat for those special-status species determined to have the potential to occur within the project site.15

3.2.2 - Vegetation
Common plant species observed during the reconnaissance-level surveys were identified by visual characteristics and morphology in the field and recorded.

This section summarizes the results of the literature search, database review, and field surveys.

Sensitive biological resources including special-status species and the impact analysis are addressed separately in Section 5 and Section 6 of this BRA.

4.1 - Environmental Setting
The 208.72-acre project site is located immediately west of the City of Cloverdale and north of Cherry Creek Road in Sonoma County, California. It is within the Porterfield Creek Watershed and is surrounded by open space to the north, south, and west and by residential development to the east.

The site is developed with dirt access roads for recreation and maintenance access. There is an existing open-walled shed in the easternmost portion of the project site in proximity to the site’s eastern access point on Foothill Boulevard, as well as an unoccupied trailer, a covered hand well, and real estate signage. An established fuel break27 borders the southeastern corner of the site adjacent to residences on Port Circle. Fencing runs along the northern and eastern boundaries, and an overhead utility line runs along the southern boundary of the site near Cherry Creek Road.

The project site is dominantly covered in native woodland, specifically California bay woodland, coast live oak forest, coast redwood forest, Douglas fir forest, and Pacific madrone forest. Southeast portions of the site are covered in native serpentine and non-native grasslands. There is an intermittent creek supporting riparian woodland and multiple drainages dispersed throughout the site.

Areas surrounding the project site consist of a mixture of low-density residential, public institutional, and undeveloped lands (Exhibit 2). Bordering the project site to the east are single-family homes. To the south and southeast are several institutional facilities, including the Clearwater Ranch Community and the Cloverdale Healthcare Center, in addition to undeveloped lands composed of oak woodland and forest. To the north are undeveloped lands composed of oak woodland and forest habitat. US101 lies approximately 1.10 miles east of the project site.

4.1.1 - Topography and Hydrology
The elevation within the project site varies, ranging from approximately 375 feet above mean sea level (AMSL) along the northeast edge to approximately 1,175 feet AMSL in the northwest corner.

Elevations along the southern boundary of the project site range from approximately 400 feet AMSL to approximately 900 feet AMSL.

There is an unnamed intermittent creek supporting riparian woodland that runs west to east along the north boundary of the site and conveys flows off-site before eventually emptying into the Cloverdale 27 A block or stirp of land where vegetation and other flammable material is removed to prevent the spread of wildfire. 342

A comprehensive list of wildlife species observed can be found in Appendix D.

4.5 - Jurisdictional Waters and Wetlands
There is an unnamed intermittent creek that runs west to east along the northern portion of the project site adjacent to the dirt access road. After leaving the site, the creek travels through neighboring wooded areas for approximately 0.25 mile before appearing to terminate at the start of the residential 352

The North Branch Porterfield Creek, also classified as intermittent riverine, traverses the southern portion of the project site north of Cherry Creek Road. After leaving the site, the creek travels through neighboring wooded areas for approximately 0.5 mile before meeting up with the main branch of Porterfield Creek, approximately 1.5 miles west of where Porterfield Creek empties into the Russian River.

4.6 - Wildlife Movement Corridors and Nursery Sites
A wildlife corridor is an area of habitat connecting wildlife populations separated by human activities or structures (such as roads, development, or logging). This allows an exchange of individuals between populations, which may help prevent the negative effects of inbreeding and reduced genetic diversity (via genetic drift) that often occur within isolated populations. The CNDDB Terrestrial Connectivity, Areas of Conservation Emphasis (ACE) Map shows that the project site is mapped as an area having connections with implementation flexibility. Adjacent to the project site on the east is the City of Cloverdale residential developments, which are mapped as having limited connection opportunity. The undeveloped forested areas to the north of the project site are mapped as conservation planning linkages, likely for the mapped irreplaceable and essential corridors much further north and west of the project site which are mostly surrounding existing wilderness preserves.
29 An FCS Biologist evaluated the CDFW’s BIOS 6 information on wildlife linkages within the project site and concluded that the proposed project does not have the potential to interfere with the movement of native wildlife. The project site has previously been used for logging and old dirt access roads exist throughout the site; however, there has not been active logging activities for many years and recent use is limited to local recreational hikers.

The forests, woodlands, and creeks on-site may provide suitable habitat connectivity for some species; however, the planned recreational trail use for the site should not be significantly different in nature from the current uses of the site. Wildlife nursery sites include nesting birds and maternity bat roosts, aquatic breeding habitats, and special-status and non-special-status wildlife breeding or nesting colonies. No significant breeding/nesting colonies were observed during field surveys; however, there were multiple avian species observed during the reconnaissance-level survey, including red-tailed, red-shouldered hawk, Nuttall's woodpecker, acorn woodpecker, ash-throated flycatcher, black-headed grosbeak, hermit warbler, and others. These species, or additional nesting birds or migratory wildlife, have the potential of being present on-site and within disturbance distance during maintenance activities. The project site contains suitable nesting habitat and wildlife movement opportunities, given the presence of open space, containing mature and relatively undisturbed oak woodlands, Douglas fir forests, California bay woodlands, and coast redwood forests. 29 California Department of Fish and Wildlife (CDFW). 2025.

The following section discusses the existing site conditions and presence or potential presence for sensitive biological resources to occur within the project site.

5.1 - Sensitive Natural Communities
Sensitive natural communities are vegetation communities or special wildlife habitats that are rare or occur in limited distributions or provide specific habitat requirements for special-status plant or wildlife species. The CDFW maintains a list of natural communities which attempts to classify vegetation types found within the State of California and rank them based on rarity. Communities ranked S1–S3 are considered sensitive natural communities that are protected under CEQA.30 The CDFW maintains a geodatabase of sensitive natural communities in the CNDDB that were entered in the mid-1990s using a previous classification system. CDFW recommends that these “Legacy Sensitive Natural Communities” be classified using the current MCV system and that they be addressed in the environmental review process under the new classification and current sensitivity rankings. Wetlands and riparian habitats are also typically considered sensitive natural communities and are addressed in the environmental review process.

No Legacy Sensitive Natural Communities have been recorded within 10 miles of the project site. 31 Five CDFW sensitive natural communities occur on the project site and are described in further detail below: California bay woodland, small fescue-dwarf plantain serpentine flower field, manzanita chaparral, needle grass-melic grass serpentine grassland, and redwood forest.

5.1.1 - California Bay Riparian Woodland
California bay woodland is present surrounding the unnamed intermittent drainage along the north boundary of the site. California bay is the dominant tree species in this riparian woodland with scattered bigleaf maple and some black oak also present. This vegetation community corresponds to the 74.100.00 Umbellularia californica Alliance on the CDFW Sensitive Natural Communities List.

This vegetation community is described in detail in Section 4.2.2 above. There is approximately 0.49 acre of California bay woodland in the temporary impact areas and approximately 0.49 acre in the permanent impact areas. However, the proposed project would limit impacts to the California bay woodland present on-site, as described in Section 6.1.1 below. 30 California Department of Fish and Wildlife (CDFW). 2023.

5.1.2 - Manzanita Chaparral
Manzanita chaparral is present along two small sections of the existing dirt acces roads near the center of the site. Manzanita is the dominant species in this shrubland community, with a sparse to moderate herbaceous understory of native species. This vegetation community corresponds to the

37.323.00 Arctostaphylos (canescens, manzanita, stanfordiana) Alliance on the CDFW Sensitive Natural Communities List. This vegetation community is described in detail in Section 4.2.7 above.

There is approximately 0.003 acre of manzanita chaparral in the permanent impact areas and none in the temporary impact areas. However, the proposed project would avoid all impacts to the manzanita chaparral present on-site, as described in Section 6.1.2 below.

5.1.3 - Needle Grass-Melic Grass Serpentine Grassland
Needle grass-melic grass serpentine grassland is present in the southeast portion of the site. Purple needle grass is the characteristic grass species of this community, with California oatgrass also present in certain areas. This vegetation community corresponds to the 41.151.00 Nassella spp.- Melica spp. Alliance on the CDFW Sensitive Natural Communities List. This vegetation community is described in detail in Section 4.2.9 above. There is approximately 0.10 acre of needle grass-melic grass serpentine grassland in the temporary impact areas and approximately 0.08 acre in the permanent impact areas. However, the proposed project would limit impacts to the needle grassmelic grass serpentine grassland present on-site, as described in Section 6.1.3 below.

5.1.4 - Redwood Forest
Redwood forest is present surrounding in the northern sections of the site, surrounding the unnamed intermittent creek and in the new trail to be added section. This vegetation community is composed of stands of coast redwood with no other dominant tree species. The understory is parse with native shrubs, including tanoak and wild rose. This vegetation community corresponds to the 86.100.00 Sequoia sempervirens Alliance on the CDFW Sensitive Natural Communities List. This vegetation community is described in detail in Section 4.2.10 above. There is approximately 0.54 acre of redwood forest in the temporary impact areas and approximately 0.53 acre in the permanent impact areas. However, the proposed project would limit impacts to the redwood forest present on-site, as described in Section 6.1.4 below.

5.1.5 - Small Fescue-Dwarf Plantain Serpentine Flower Field Small fescue-dwarf plantain serpentine flower fields are present in patches surrounding the dirt access road in a few sections of the site. Small fescue, dwarf plantain, and hairy cat’s ear are the dominant plants in the serpentine-specific herbaceous community, with California oatgrass present in scattered areas. This vegetation community corresponds to the 44.108.04 Vulpia microstachysPlantago erecta Association on the CDFW Sensitive Natural Communities List. This vegetation community is described in detail in Section 4.2.11 above. There is approximately 0.01 acre of small fescue-dwarf plaintain serpentine flower field in the permanent impact areas and none in the 357

However, the proposed project would avoid all impacts to the small fescuedwarf plantain serpentine flower fields present on-site, as described in Section 6.1.5 below.

5.2 - Special-status Plant Species
Fifty-eight special-status plant species have been recorded within the nine-quadrangle region of the project site (Exhibit 6; Appendix B, Table 1). Table 1 in Appendix B includes the species’ status, required habitat, and a summary analysis of the potential for each of these species to occur within the project site. Special-status plant species that were determined to have no potential or low potential to occur on-site are included in the table, along with the justification for their exclusion from further discussion. The potential for a species to occur in the project site was based on presence of suitable habitats, soil types, and occurrences recorded by the CNPS Inventory, CNDDB, and Calflora. 32,33,34,35
Previous existing structures and dirt access roads and the abundance of several non-native, invasive, annual plant species may have lowered the potential for persistence and occurrence of populations of many special-status plant species within much of the temporary impact areas.

Seven special-status plant species have at least a moderate potential to occur within the project site and are therefore discussed in further detail below: Howell’s manzanita (Arctostaphylos hispidula), serpentine reed grass (Calamagrostis ophitidis), Rincon Ridge ceanothus (Ceanothus confusus), congested-headed hayfield tarplant (Hemizonia congesta ssp. congesta), bristly leptosiphon (Leptosiphon aureus), Cobb Mountain lupine (Lupinus sericatus), and bearded jewelflower (Streptanthus barbiger).

5.2.1 - Howell’s Manzanita
Howell’s manzanita is a perennial shrub in the Ericaceae family found in chaparral in sandstone, serpentine soils. Howell’s manzanita typically blooms March through April. This species has been assigned a CRPR of 4.2 from CNPS. There was one recent occurrence recorded approximately 5.5 miles southwest of the project site, on the west side of Lake Sonoma. There is potentially suitable habitat for this species in the manzanita chaparral on the project site.

5.2.2 - Serpentine Reed Gass
Serpentine reed grass is a perennial herb in the Poaceae family found in chaparral, lower montane coniferous forest, meadows and seeps, and valley and foothill grassland in rocky, serpentine soils.

Serpentine reed grass typically blooms in the months of April through July. This species has been 32 California Department of Fish and Wildlife (CDFW). 2025.

5.2.7 - Bearded Jewelflower
Bearded jewelflower is an annual herb in the Brassicaceae family found in chaparral in serpentine soils. Bearded jewelflower typically blooms May through July. This species has been assigned a CRPR of 4.2 from CNPS. There have been two recent checklist occurrences recorded within 5 miles of the project site. There is potentially suitable habitat for this species in the manzanita chaparral on the project site.

5.3 - Special-status Wildlife Species
The CNDDB and IPaC identify 16 federal and State-listed threatened and/or endangered wildlife species and State Species of Special Concern (SSC) that have been recorded within the Cloverdale, California USGS Topographic Quadrangle Map and eight surrounding quadrangles. The CNDDB occurrences near the project site are shown on Exhibit 6. The Special-status Wildlife Species Evaluation Table (Appendix B, Table 2) includes the species’ status, required habitat types and features, and potential to occur within the project site. The table also includes special-status wildlife species that have been determined to have no potential to occur on-site, primarily based on the absence of suitable habitat and the lack of recorded occurrence in the project vicinity, along with other justification(s) for their exclusion from further discussion.

Four special-status wildlife species have at least a low potential to occur within the project site and are therefore discussed in further detail below: Foothill yellow-legged frog (Rana boylii), Crotch’s bumble bee (Bombus crotchii), northwestern pond turtle (Actinemys marmorata), and purple martin (Progne subis).

5.3.1 - Foothill Yellow-legged Frog
Foothill yellow-legged frog is a SSC protected by the CDFW and has a moderate potential to occur on-site. This species is typically found in partly shaded shallow streams and riffles with a rocky substrate in a variety of habitats. The species requires at least some cobble-sized substrate for egglaying and at least 15 weeks to attain metamorphosis. Project site contains marginally suitable drainages and a creek with riparian woodland. However, the existing aquatic features on-site do not contain the required microhabitat, specifically cobble-sized substrate, to support larvae and breeding activities. One CNDDB occurrence was recorded approximately 0.5 mile southwest of the project site along Cherry Creek Road in 2002. Additionally, one occurrence was previously recorded approximately 0.75 mile south of the project site, along Porterfield Creek, in 2018.

5.3.2 - Crotch’s Bumble Bee
Crotch’s bumble bee is a candidate for listing and receives protections under the Endangered Species Act and has a moderate potential to occur on-site. The are typically found in coastal California east to the Sierra-Cascade crest and south into Mexico. Food plant genera include Antirrhinum, Phacelia, Clarkia, Dendromecon, Eschscholzia, and Eriogonum. The project site contains the required host plant Eschscholzia, Clarkia, and Eriogonum for foraging to support this species. One CNDDB occurrence was recorded approximately 9.5 miles south of project site in 2023. 362

Https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/4859/48590006/BRA/48590006 Soda Springs Ranch Open Space Preserve BRA.docx Because of the suitable host plants on-site, and recent occurrence within the project vicinity, it cannot be ruled out that Crotch’s bumble bee individuals could occupy the site. Ground-disturbing activities, including vegetation removal, could result in potentially significant impacts to Crotch’s bumble bee.

5.3.3 - Northwestern Pond Turtle
Northwestern pond turtle is proposed threatened under the Endangered Species Act and a SSC protected by the CDFW and has a moderate potential to occur on-site. This species is thoroughly aquatic turtle found in ponds, marshes, rivers, streams, and irrigation ditches, usually with aquatic vegetation below 6,000 feet elevation. The species requires basking sites and suitable upland habitat (sandy banks or grassy open fields) up to 0.5 km from water for egg-laying. The project site contains drainages and a creek that supports riparian woodland and nearby grassland habitat. Two CNDDB occurrences were recorded in 2002 within the Russian River approximately 1 mile east of project site, within dispersal distance, and approximately 3.5 miles southeast of project site. Because of the recent occurrences in proximity of the Russian River and suitable aquatic features to support this species, it cannot be ruled out northwestern pond turtle individuals could occupy the site.

5.3.4 - Protected Nesting Birds (Including Purple Martin and All Special-status Avian Species)
The project site’s existing trees, shrubs, and riparian woodland habitats may provide potential nesting habitat for birds, including purple martin. The entirety of the project site, channel banks and riparian vegetation along Salvador Channel, and areas adjacent to the project site contain a number of trees and shrubs that could provide potential nesting habitat could be used by the special-status birds.

Should these be present, construction-related activities could result in their loss, which would result in a significant impact to special-status bird species.

5.4 - State and Federally Protected Waters and Wetlands The project site contains North Branch Porterfield Creek, which feeds into to the main Porterfield Creek, which is a tributary to the Russian River; and an unnamed intermittent creek that feeds into the Cloverdale Creek, which is also a tributary to the Russian River. The Russian River is considered waters of the US and waters of the State, and as intermittent tributaries the North Branch Porterfield Creek and the unnamed intermittent creek would also be potentially considered waters of the US under the jurisdiction of the USACE and waters of the State under the jurisdiction of CDFW and the RWQCB.

5.5 - Protected Trees
As described in Section 4.4 above, the project site contains many native tree species that are listed in the City of Cloverdale Tree Protection Ordinance, including black oak, valley oak, blue oak, interior live oak, coast live oak, Oregon oak, California bay, coast redwood, Douglas fir, and ponderosa pine.

Many of these meet the minimum DBH size requirement to be considered protected under the City’s Tree Ordinance and are within the project temporary or permanent impact areas. 363

The following discussion addresses potential project impacts on sensitive biological resources, including special-status species, and recommends measures to avoid and/or mitigate impacts to a less than significant level under CEQA. Potential project-related temporary impacts are depicted in Exhibit 7a, and permanent impacts are depicted in Exhibit 7b, respectively.

6.1 - Impact Analysis for Sensitive Natural Communities Five sensitive natural communities, as identified on the CDFW Sensitive Natural Communities List, occur on the project site and are addressed below: California bay woodland, manzanita chaparral, needle grass-melic grass serpentine grassland, coast redwood forest, and small fescue-dwarf plantain serpentine flower field

6.1.1 - California Bay Woodland
California bay woodland is present surrounding the unnamed intermittent drainage along the north boundary of the site. This vegetation community corresponds to the 74.100.00 Umbellularia californica Alliance on the CDFW Sensitive Natural Communities List. The proposed project will not be removing any trees within this community and impacts would be limited to removal of dead trees and trimming of shrubs where they overgrow the existing dirt access road. As such, the impacts of the proposed project on this community would be considered less than significant.

6.1.2 - Manzanita Chaparral
Manzanita chaparral is present along two small sections of the existing dirt acces roads near the center of the site. This vegetation community corresponds to the 37.323.00 Arctostaphylos (canescens, manzanita, stanfordiana) Alliance on the CDFW Sensitive Natural Communities List.

There are no shrubs overgrowing the dirt access road in this community and none of the trails to be added or culverts to be replaced are located within this community. There are no planned project activities within this community; therefore, the proposed project should not have any impacts on this community.

6.1.3 - Needle Grass-Melic Grass Serpentine Grassland
Needle grass-melic grass serpentine grassland is present in the southeast portion of the site. This vegetation community corresponds to the 41.151.00 Nassella spp.-Melica spp. Alliance on the CDFW Sensitive Natural Communities List. There are no shrubs overgrowing the dirt access road in this community and none of the culverts to be replaced are located within this community; however; one of the new trails to be added meets the dirt access road in this community. This section of the proposed new trail to be added is relatively flat with no shrubs or emergent trees and should not significantly disturb this community. Additionally, the section of this community that will be impacted by 364

Https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/4859/48590006/BRA/48590006 Soda Springs Ranch Open Space Preserve BRA.docx the new trail to be added already surrounds an existing dirt access road that has resulted in the presence of non-native and invasive plant species. Therefore, the proposed new trail in this vegetation community would not significantly change the species composition and impacts would be considered less than significant.

6.1.4 - Redwood Forest
Coast redwood forest is present surrounding in the northern sections of the site, surrounding the unnamed intermittent creek and in the new trail to be added section. This vegetation community corresponds to the 86.100.00 Sequoia sempervirens Alliance on the CDFW Sensitive Natural Communities List. The project does not propose the removal of any coast redwood trees protected under the City Tree Ordinance, so all coast redwood trees at least 48 inches in diameter would be preserved, per the direction of the City Arborist. The construction of proposed new trails would include cuts into the hillside, and shrubs and smaller trees would likely be removed. However, the preservation of the large coast redwood trees should allow for the community to recover after the disturbances; therefore, the impacts of the proposed project on this community would be considered less than significant.

6.1.5 - Small Fescue-Dwarf Plantain Serpentine Flower Field Small fescue-dwarf plantain serpentine flower fields are present in patches surrounding the dirt access road in a few sections of the site. This vegetation community corresponds to the 44.108.04 Vulpia microstachys-Plantago erecta Association on the CDFW Sensitive Natural Communities List.

There are no shrubs overgrowing the dirt access road in this community and none of the trails to be added or culverts to be replaced are located within this community. There are no planned project activities within this community; therefore, the proposed project should not have any impacts on this community.

6.2 - Impact Analysis for Special-status Plant Species
Seven special-status plant species were assessed as having at least a moderate potential to occur within the project site: Howell’s manzanita, serpentine reed grass, Rincon Ridge ceanothus, congested-headed hayfield tarplant, bristly leptosiphon, Cobb Mountain lupine, and bearded jewelflower. Compliance with Mitigation Measure (MM) BIO-1 would ensure potential project-related impacts to special-status plant species would be reduced to a less than significant level.

MM BIO-1 Protocol-level Rare Plant Surveys
A qualified Plant Biologist shall conduct three surveys within the Rare Plant Survey Area (see Exhibit 8) for special-status plant species according to the California Department of Fish and Wildlife (CDFW) Protocols for Surveying and Evaluating Impacts to Special-status Native Plant Populations and Sensitive Natural Communities (2018, rev. 2021). These surveys shall be timed to capture the local blooming period of special-status plant species with a moderate to high potential to occur on-site, including Howell’s manzanita, serpentine reed grass, Rincon Ridge ceanothus, congested-headed hayfield tarplant, bristly leptosiphon, Cobb Mountain lupine, and bearded jewel flower.

If any special-status plant species are found within the project site impact area, the occurrences shall be mapped, recorded, and submitted to the California Natural Diversity Database (CNDDB). The Rare Plant Survey Report shall detail any specialstatus plant species or sensitive natural communities found on-site, as well propose potential avoidance or mitigation measures based upon specific occurrences. 370

6.3 - Impact Analysis for Special-status Wildlife Species

6.3.1 - Foothill Yellow-legged Frog
Foothill yellow-legged frog was assessed as having a low potential to occur within the project site.

Construction activities within the project site, within or adjacent to existing aquatic features and associated riparian habitat, could result in direct harm to foothill yellow-legged frog and their burrows, while noise, light, and other anthropogenic disturbances may cause indirect impacts to frogs and prematurely abandon their burrows. Compliance with MM BIO-2 would ensure potential projectrelated impacts to protected foothill yellow-legged frog would be reduced to a less than significant level.

MM BIO-2 Pre-construction Surveys and Avoidance of Foothill Yellow-legged Frog To the extent practicable, the applicant shall avoid construction during the wet season when foothill yellow-legged frog (FYLF) are most active. Except for limited vegetation clearing (necessary to minimize effects to nesting birds) work shall be limited to the dry season (from June 1 to October 31.

No more than 15 days prior to the first ground-disturbing activities, the applicant shall retain a qualified Wildlife Biologist to conduct a focused survey for FYLF within the ground disturbance area and immediate vicinity to determine presence or absence of this species. If the species is observed within the Study Area during the focused survey, the California Department of Fish and Wildlife (CDFW) shall be contacted and all construction activities within the disturbance area shall be delayed until an appropriate course of action is established and approved by CDFW.

Before any activities begin on the project, the applicant shall retain an approved Biologist to conduct Worker Environmental Awareness Program (WEAP) training for all construction personnel. At a minimum, the training shall include a description of the FYLF and its habitat, the specific measures that are being implemented to conserve the FYLF for the current project, and the boundaries within which the project may be accomplished. Brochures, books, and briefings may be used in the WEAP, provided that a qualified person is on hand to answer any questions.

The applicant shall limit the number of access routes, size of staging areas, and the total area of the construction activity to the minimum necessary to achieve the project goal. Environmentally Sensitive Areas (ESAs) shall be established to confine access routes and construction areas to the minimum area necessary to complete construction, and minimize the impact to FYLF habitat; this goal includes locating access routes and construction areas outside of riparian areas to the maximum extent practicable.

6.3.2 - Crotch’s Bumble Bee
Crotch’s bumble bee was assessed as having a moderate potential to occur within the project site.

Construction activities within the project site, within or adjacent to on-site areas containing suitable habitat and/or host plants, could result in direct harm to Crotch’s bumble bee and their hives, while noise, light, and other anthropogenic disturbances may cause indirect impacts to queens and prematurely abandon their hives. Compliance with MM BIO-3 would ensure potential project-related impacts to protected Crotch’s bumble bee would be reduced to a less than significant level.

MM BIO-3 Protocol-level Crotch’s Bumble Bee Surveys
A qualified Biologist shall conduct focused Crotch’s bumble bee surveys, in accordance with survey guidelines described in the 2023 California Department of Fish and Wildlife (CDFW) Survey Considerations for California Endangered Species Act (CESA) Candidate Bumble Bee Species, within 1 year of initiation of grounddisturbing activities (i.e., grubbing, grading, disking, etc.). If the focused surveys are positive for Crotch’s bumblebee, the project applicant shall obtain take authorization under CESA in the form of an Incidental Take Permit (ITP) issued by CDFW prior to conducting any ground-disturbing activities. Mitigation measures outlined in the ITP shall be used to offset impacts to this species.

Areas scheduled for grading and/or vegetation shall be revegetated utilizing an assemblage of native upland vegetation suitable for the area. Invasive, exotic plants shall be controlled to the maximum extent practicable during construction. This measure shall be implemented in all areas disturbed by activities associated with the project unless the CDFW, the United States Fish and Wildlife Service (USFWS), and the project applicant determine that it is not feasible or practical.

6.3.3 - Northwestern Pond Turtle
Northwestern pond turtle was assessed as having a moderate potential to occur within the project site. Construction activities within the project site, within or adjacent to existing aquatic features and associated riparian habitat, could result in direct harm to northwestern pond turtle and their burrows, while noise, light, and other anthropogenic disturbances may cause indirect impacts to turtles and prematurely abandon their burrows. Compliance with MM BIO-4 would ensure potential projectrelated impacts to protected northwestern pond turtle would be reduced to a less than significant level.

MM BIO-4 Pre-construction Surveys and Avoidance of Northwestern Pond Turtle A qualified Biologist with relevant survey experience shall conduct a survey within the project site impact area for northwestern pond turtle no more than 5 days prior to beginning ground disturbance and/or construction. If any life stage of the northwestern pond turtle is detected, construction activities shall not be allowed to 375

Before any activities begin on the project, a qualified Biologist shall conduct a Worker Environmental Awareness Program (WEAP) for all construction personnel. At a minimum, the training will include a description of the northwestern pond turtle and its habitat, the specific measures that are being implemented to conserve the northwestern pond turtle for the current project, and the boundaries within which the project may be accomplished. Barrier fencing shall be installed around the worksite to prevent northwestern pond turtle from entering the work area. A qualified Biologist shall be present during the installation of exclusion fencing. Barrier fencing shall be removed within 72 hours of completion of work.

Areas scheduled for grading and/or vegetation shall be revegetated utilizing an assemblage of native upland vegetation suitable for the area.  Invasive, exotic plants shall be controlled to the maximum extent practicable during construction. This measure shall be implemented in all areas disturbed by activities associated with the project unless the CDFW, the USFWS, and the project applicant determine that it is not feasible or practical.

6.3.4 - Protected Nesting Birds (Including Purple Martin and All Special-status Avian Species)
Many bird species covered under the MBTA were observed on-site, including California scrub jay (Aphelocoma californica), oak titmouse, red-tailed hawk, red-shouldered hawk, California quail (Callipepla californica), Anna's hummingbird (Calypte anna), turkey vulture (Cathartes aura), common raven (Corvus corax), Steller's jay (Cyanocitta stelleri), Nuttall’s woodpecker, western flycatcher (Empidonax difficilis), dark-eyed junco (Junco hyemalis), orange-crowned warbler (Leiothlypis celata), acorn woodpecker, ash-throated flycatcher, black-headed grosbeak, chestnut-backed chickadee (Poecile rufescens), hermit warbler, white-breasted nuthatch (Sitta carolinensis), lesser goldfinch (Spinus psaltria), violet-green swallow (Tachycineta thalassina), warbling vireo (Vireo gilvus), and Hutton's vireo (Vireo huttoni). Additionally, the purple martin was assessed as having a low potential to occur within the project site. Construction activities that occur during the avian nesting season (generally February 1 to August 31) could significantly disturb or destroy nesting sites for bird species protected under the Fish and Game Code or MBTA. The removal of trees during the nesting season could result in direct harm to nesting birds, while noise, light, and other anthropogenic disturbances may cause nesting birds to prematurely abandon their nests. Compliance with MM BIO-5 would ensure potential project-related impacts to protected nesting birds, including the purple martin, would be reduced to a less than significant level.

Https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/4859/48590006/BRA/48590006 Soda Springs Ranch Open Space Preserve BRA.docx If the proposed project initiates construction/maintenance activities during the avian nesting season, the project applicant shall retain a qualified Biologist to perform preconstruction surveys for nesting birds, including purple martin. The survey shall be conducted 5 days prior to the initiation of project activities to determine whether active nests are present. If an active nest is located, the qualified Biologist shall determine an appropriately sized avoidance buffer based on the species and anticipated disturbance level. A qualified Biologist will delineate the avoidance buffer using Environmentally Sensitive Area (ESA) fencing, pin flags, and or yellow caution tape. No construction/maintenance activities or other foot traffic is allowed to occur within the avoidance buffer(s). The ESA buffer zone shall be maintained around the active nest site(s) until the qualified Biologist determines that the young have fledged and are foraging independently. The qualified Biologist shall monitor the active nest during maintenance and/or construction activities and stop or divert project activities in the vicinity, as needed, to prevent any potential impacts that may result from the construction of the proposed project until the young have fledged.

6.4 - Impact Analysis for Wildlife Movement Corridors and Nursery Sites
Based on the Essential Connectivity Areas geospatial data set, which uses habitat modeling to identify areas of land with value as wildlife corridors, the project site is situated well outside of any essential habitat corridors.
36 Moreover, and as noted in Section 4.6 of this BRA, based on the CNDDB Terrestrial Connectivity, ACE Map, the project site is located in an area considered to have connections with implementation flexibility, allowing marginal wildlife movement on-site, however, does not serve as an essential wildlife movement corridor. The project site is adjacent to residential development to the east and Cherry Creek Road to the south, which are mapped as having limited connection opportunity. The rest of the project site is directly bounded by undeveloped forest and woodland that is mapped as conservation planning linkages.37 Because of the adjacent residential development and Cherry Creek Road, it is unlikely that the project site would provide corridor functions for any species that are not already present, including urbanized wildlife species such as coyotes, wild turkeys, raccoons, skunks, and squirrels. Moreover, as noted in Section 1.2 the proposed project would establish a conservation easement over the site, resulting in the closure of unnecessary trails, the repair of existing roads, the development of multiuse trails, and does not constitute development that would have the potential to substantially interfere with wildlife movement.

Therefore, the project site is not likely to function as a wildlife movement corridor. 36 California Department of Fish and Wildlife (CDFW) and California Department of Transportation (Caltrans). 2025.

No significant breeding/nesting colonies were observed during the field survey. However, individual nesting birds have the potential of being present on-site, during nesting seasons. Potential impacts to individual nesting birds are addressed through the implementation of MM BIO-5. As such, impacts to wildlife nursery sites would be less than significant.

6.5 - Impact Analysis for State and Federally Protected Waters and Wetlands
The project site contains two potentially jurisdictional waters: the North Branch Porterfield Creek in the southern section of the project site and the unnamed intermittent creek along the north boundary of the project site, both of which are hydrologically connected to the Russian River, which is considered a water of the United States and water of the State. The proposed project would not include work within the OHWM so there should be no direct impacts to federally jurisdictional waters.

The proposed project would result in impacts to the riparian corridor that are potentially under the jurisdiction of CDFW and the RWQCB. Compliance with MM BIO-6a through MM BIO-6c would ensure potential project-related impacts to jurisdictional waters would be reduced to a less than significant level.

MM BIO-6a Avoidance and Minimization of Impacts to Aquatic Features and Riparian Habitat
The applicant shall ensure that no substances toxic to fish and wildlife shall be discharged or allowed to leach into the existing aquatic features on-site. Reasonable precautions to protect aquatic habitats of the potentially jurisdictional features from pollution with harmful materials (e.g., fuels, oils, lubricants, and solvents) shall be implemented. Specifically, all potentially hazardous materials shall be controlled, cleaned up, and properly disposed of in accordance with the proposed project’s water quality control permits and plans. Materials deleterious or toxic to fish and wildlife, including, but not limited to, asphalt, tires, concrete, construction materials, treated wood, and creosote-containing materials, shall not be stockpiled within 100 feet of the existing drainage features. Refueling and maintenance areas for equipment shall be limited to areas 100 feet from the existing drainage features on-site.

At no time shall silt-laden runoff be allowed to enter the drainage features. Erosion control measures shall be utilized throughout all phases of construction where sediment runoff from the proposed project may enter the aquatic features. Best Management Practices (BMPs) to avoid erosion and uncontrolled stormwater runoff shall be implemented. BMPs typically include silt fencing, coir rolls, and/or straw bale dikes.

Https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/4859/48590006/BRA/48590006 Soda Springs Ranch Open Space Preserve BRA.docx The project applicant, after coordination with the California Department of Fish and Wildlife (CDFW), shall obtain and file a notification of a Streambed Alteration Agreement, if and to the extent required by applicable laws and regulations, prior to conducting construction and/or maintenance activities within any aquatic resources or associated riparian habitat that may qualify as streams or sensitive natural communities under CDFW jurisdiction (i.e., those having bed and bank and at least periodical flow). If required, the project applicant shall implement all mitigation measures, imposed by the CDFW, related to the subject Streambed Alteration Agreement, which may include but not be limited to the implementation of erosion and bank stabilization measures, seasonal work restrictions, and/or restoration and revegetation of the riparian corridor, as determined by the CDFW.

MM BIO-6c Obtain Appropriate Permits Prior to Construction (CWA Sections 404/401 or Waste Discharge Requirement)
Prior to the fill of any potentially jurisdictional waters as part of the proposed project, the project applicant shall consult with the United States Army Corp of Engineers (USACE) to determine the extent, if at all, that waters of the United States may be impacted by the proposed project.

The applicant shall obtain a Section 404 Clean Water Act (CWA) permit for impacts to waters of the United States and Section 401 Water Quality Certification from the Regional Water Quality Control Board (RWQCB). These permits and certifications shall be obtained prior to issuance of grading permits for the implementation of the proposed project. If the existing drainage features on-site are found to be exempt from being regulated by the USACE as a water of the United States, the applicant shall consult with the RWQCB and obtain a Waste Discharge Requirement (WDR) if deemed necessary. The applicant shall design the proposed project to result in no net loss of functions and values of waters of the United States by incorporating impact avoidance, impact minimization, and/or compensatory mitigation for the impact, as determined in the CWA 404/401 or WDR.

Compensatory mitigation may consist of (1) obtaining credits from a mitigation bank; (2) making a payment to an in lieu fee program that will conduct wetland, stream, or other aquatic resource restoration, creation, enhancement, or preservation activities; and/or (3) providing compensatory mitigation through an aquatic resource restoration, establishment, enhancement, and/or preservation activity. This final type of compensatory mitigation may be provided at or adjacent to the impact site (i.e., onsite mitigation) or at another location, usually within the same watershed as the permitted impact (i.e., off-site mitigation). The project/permit applicant retains responsibility for the implementation and success of the mitigation project. 379

6.6 - Protected Trees
The proposed project would adhere to General Plan Policies LU 3-4, CDO 6-1, CDO 6-2, CDO 6-3, CDO 6-4, CDO 6-5, CDO 7-1 through project design features. The proposed project would adhere to the City’s Tree Ordinance through project design features, obtaining the required permits, if necessary, BMPs, and tree avoidance to preserve City protected trees and heritage trees on-site to the maximum extent possible. All trees proposed for removal are downed and considered a hazard on-site and therefore would be exempt from the City’s Tree Ordinance. All other protected trees onsite would be avoided and preserved as a part of the proposed design through consultation with the City Arborist. The proposed project would not conflict with any local policies or ordinances protecting biological resources, including protected trees; therefore, impacts would be less than significant.

6.7 - Conflict with Habitat Conservation Plans
The project site does not fall under an adopted HCP/Natural Community Conservation Plan (NCCP), or other approved local, regional, or State HCP. However, the project site will be subject to the Sonoma County HCP, currently under review, once adopted by the County. Therefore, the proposed project would not conflict with the provisions of any current adopted regional conservation plan and no impacts would occur.

Dicamptodon ensatus
California giant salamander
— SSC Known from wet coastal forests near streams and seeps from Mendocino County south to Monterey County, and
east to Napa County. Aquatic larvae found in cold, clear streams, occasionally in lakes and ponds. Adults known
from wet forests under rocks and logs near streams and
lakes.

Unlikely to Occur: Project site contains marginally
suitable riparian woodland, drainages, a creek, and
seeps to support this species. One occurrence recorded
~0.5 mile southwest of project site in 1988. Two
historical occurrences recorded ~7.5 miles south of
project site in 1955. Due to the 37-year lapse since the last recorded occurrence, and lack of suitable streams
and lake habitat, this species is unlikely to occur on the project site.

Rana boylii pop. 1
foothill yellow-legged frog -
north coast DPS
— SSC Found in partly shaded shallow streams and riffles with a rocky substrate in a variety of habitats. Needs at least some cobble-sized substrate for egg-laying and at least 15 weeks to attain metamorphosis.

Moderate Potential to Occur: Project site contains
drainages and a creek with riparian woodland. One
occurrence recorded ~0.5 mile southwest of project site in 2002 along Cherry Creek Road. One occurrence
recorded ~0.75 mile south of project site in 2018 along Porterfield Creek. Due to the recent occurrence of the
foothill yellow-legged frog within dispersal distance,
there is a moderate potential for the species to occur
within the project site.

—
MBTA
SSC Found in dense grasslands on rolling hills, lowland plains, in valleys, and on hillsides on lower mountain slopes.

Favors native grasslands with a mix of grasses, forbs,
and scattered shrubs. A loosely colonial species when
nesting.

Unlikely to Occur: Project site contains marginally
suitable native grasslands on hill slopes to support this species. One CNDDB occurrence has been recorded
within 10 miles of the project site in 1991. Due to the 34- year lapse since the last recorded occurrence, distance from site, and lack of suitable habitat, this species is unlikely to occur on the project site.

Progne subis
purple martin
—
MBTA
SSC Inhabits woodlands, low elevation coniferous forest of Douglas-fir, ponderosa pine, and Monterey pine. Nests in old woodpecker cavities mostly; also in human-made
structures. Nest often located in tall, isolated tree/snag.

Low Potential to Occur: Project site contains
marginally suitable Douglas-fir forest and redwood forest habitat to support this species. One occurrence recorded ~5.5 miles south of project site in May 2025, along Lake Sonoma. Due to the recent occurrence and marginally
suitable habitat, this species has a low potential to occur on-site.

Mammals
Antrozous pallidus
pallid bat
— SSC Found in deserts, grasslands, shrublands, woodlands, and forests. Most common in open, dry habitats with
rocky areas for roosting. Roosts must protect bats from high temperatures. Species is very sensitive to
disturbance of roosting sites.

Unlikely to Occur: Project site contains chaparral,
Douglas-fir forest, mixed oak woodland, coast live oak
woodland and grassland, and has low levels of
anthropogenic activity on site.

One occurrence recorded ~3.5 miles east of project site in 1976. One occurrence recorded ~9 miles north of
project site in 1927. Due to the 49 years since the last recorded occurrence and lack of suitable microhabitat to support roosting activities, this species is unlikely to occur on the project site.

western red bat
— SSC Roosts primarily in trees, 2-40 ft above ground, from sea level up through mixed conifer forests. Prefers habitat edges and mosaics with trees that are protected from
above and open below with open areas for foraging.

Unlikely to Occur: Project site contains Douglas-fir
forest and redwood forest. One occurrence recorded ~2
mile east of project site in 1954. Due to the 71 years
since the last recorded occurrence and lack of suitable microhabitat to support roosting activities, this species is unlikely to occur on the project site.

Reptiles
Actinemys marmorata
northwestern pond turtle
— SSC This species is a thoroughly aquatic turtle found in ponds, marshes, rivers, streams, and irrigation ditches, usually with aquatic vegetation below 6000 feet elevation.

Requires basking sites and suitable upland habitat
(sandy banks or grassy open fields) up to 0.5 km from
water for egg-laying.

Moderate Potential to Occur: Project site contains
drainages and a creek with riparian woodland and
nearby grassland habitat. Two occurrences recorded in
2002 within the Russian River ~1 mile east of project site and ~3.5 miles southeast of project site. Due to the
recent occurrence of the foothill yellow-legged frog within dispersal distance, and marginally suitable breeding
habitat, there is a moderate potential for the species to occur within the project site.

Via Email to: [email protected] & [email protected] Re: Native American Tribal Consultation, Pursuant to the Assembly Bill 52 (AB 52), Amendments to the California Environmental Quality Act (CEQA) (Chapter 532, Statutes of 2014), Public Resources Code Sections 5097.94 (m), 21073, 21074, 21080.3.1, 21080.3.2, 21082.3, 21083.09, 21084.2 and 21084.3, Soda Springs Ranch Open Space Preserve Project, Sonoma County To Whom It May Concern:

Pursuant to Public Resources Code section 21080.3.1 (c), attached is a consultation list of tribes that are traditionally and culturally affiliated with the geographic area of the above-listed project. Please note that the intent of the AB 52 amendments to CEQA is to avoid and/or mitigate impacts to tribal cultural resources, (Pub. Resources Code §21084.3 (a)) (“Public agencies shall, when feasible, avoid damaging effects to any tribal cultural resource.”) Public Resources Code sections 21080.3.1 and 21084.3(c) require CEQA lead agencies to consult with California Native American tribes that have requested notice from such agencies of proposed projects in the geographic area that are traditionally and culturally affiliated with the tribes on projects for which a Notice of Preparation or Notice of Negative Declaration or Mitigated Negative Declaration has been filed on or after July 1, 2015. Specifically, Public Resources Code section 21080.3.1 (d) provides:

Within 14 days of determining that an application for a project is complete or a decision by a public agency to undertake a project, the lead agency shall provide formal notification to the designated contact of, or a tribal representative of, traditionally and culturally affiliated California Native American tribes that have requested notice, which shall be accomplished by means of at least one written notification that includes a brief description of the proposed project and its location, the lead agency contact information, and a notification that the California Native American tribe has 30 days to request consultation pursuant to this section.

The AB 52 amendments to CEQA law does not preclude initiating consultation with the tribes that are culturally and traditionally affiliated within your jurisdiction prior to receiving requests for notification of projects in the tribe’s areas of traditional and cultural affiliation. The Native American Heritage Commission (NAHC) recommends, but does not require, early consultation as a best practice to ensure that lead agencies receive sufficient information about cultural resources in a project area to avoid damaging effects to tribal cultural resources.

The NAHC also recommends, but does not require that agencies should also include with their notification letters, information regarding any cultural resources assessment that has been completed on the area of potential effect (APE), such as:

1. The results of any record search that may have been conducted at an Information Center of the California Historical Resources Information System (CHRIS), including, but not limited to:

• A listing of any and all known cultural resources that have already been recorded on or adjacent to the APE, such as known archaeological sites;
• Copies of any and all cultural resource records and study reports that may have been provided by the Information Center as part of the records search response; • Whether the records search indicates a low, moderate, or high probability that unrecorded cultural resources are located in the APE; and
• If a survey is recommended by the Information Center to determine whether previously unrecorded cultural resources are present.

2. The results of any archaeological inventory survey that was conducted, including:
• Any report that may contain site forms, site significance, and suggested mitigation measures.

All information regarding site locations, Native American human remains, and associated funerary objects should be in a separate confidential addendum, and not be made available for public disclosure in accordance with Government Code section 6254.10.

3. The result of the Sacred Lands File (SLF) check conducted through the Native American Heritage Commission was positive. Please contact the Mishewal-Wappo Tribe of Alexander Valley on the attached list for more information.

4. Any ethnographic studies conducted for any area including all or part of the APE; and

5. Any geotechnical reports regarding all or part of the APE.

Lead agencies should be aware that records maintained by the NAHC and CHRIS are not exhaustive and a negative response to these searches does not preclude the existence of a tribal cultural resource. A tribe may be the only source of information regarding the existence of a tribal cultural resource.

This information will aid tribes in determining whether to request formal consultation. In the event that they do, having the information beforehand will help to facilitate the consultation process.

If you receive notification of change of addresses and phone numbers from tribes, please notify the NAHC. With your assistance, we can assure that our consultation list remains current.

If you have any questions, please contact me at my email address: [email protected] Sincerely,
Melina Carlos

Subject: Soda Springs Ranch Trail Project
Dear Chairperson McCloud:

FirstCarbon Solutions (FCS) is preparing an Initial Study/Mitigated Negative Declaration for the Mill Residential Project in the City of Anaheim. As part of the environmental review process, we are conducting a cultural resources assessment.

The project site is located at 275 to 375 Santa Ana Street. A Records Search map with a 0.5-mile buffer around the site is enclosed for your reference.

As part of the cultural resources assessment, FCS conducted a Sacred Lands File (SLF) search and a California Historical Resource Information (CHRIS) search. The results of the SLF records search was negative. The CHRIS search found that there were no recorded resources or reports within the project site. However, there are17 resources within a 0.5- mile radius of the project site, all of which are historic. Furthermore, there are 10 reports recorded within a 0.5-mile radius of the project site. The Native American Heritage Commission (NAHC) suggested you might be able to provide further information. If you have any additional information regarding potential historic or cultural resources in proximity or relation to the proposed project area, we would greatly appreciate your input.

Please note that this letter is a request for information pertaining to a cultural resources assessment and is not notification of a project under Senate Bill (SB) 18, Assembly Bill (AB) 52 or Section 106 of the National Historic Preservation Act.

Designated lead agencies under the California Environmental Quality Act (CEQA) and National Environmental Policy Act (NEPA) are handling project notification and consultation requirements. Please feel free to contact me at 707-591-6523or via email at [email protected] and thank you for your valuable assistance.

Subject: Proposed Soda Springs Ranch Open Space Preserve Project
Dear Vice-Chairperson Tasheena:

FirstCarbon Solutions (FCS) is is preparing a Phase I Cultural Resources Assessment (PI-CRA) for the proposed Soda Springs Ranch Open Space Preserve Project, in the City of Cloverdale, California. As part of the environmental review process, we are reaching out to the tribes for any additional information that can be incorporated into our analysis.

The City of Cloverdale (City) is proposing to acquire a conservation easement to protect the property at 600 Cherry Creek Road, known as the Soda Springs Ranch Open Space Preserve. The 208.72-acre project site corresponds to the Assessor’s Parcel Number (APN) 115-220-007, -006, and -019. The project site is undeveloped and has historically been used for timber harvest, hunting, grazing, equipment storage, personal recreation, and open space. The permanent conservation of the Soda Springs Ranch Open Space Preserve (proposed project) would place a conservation easement over the project site to protect its natural resources, scenic resources, and recreational and educational resources. In the process, the City would close eight unnecessary trails, repair remaining roads to allow access to City maintenance vehicles, create three new multiuse trails, 5 picnic sites, fencing, as well as a parking area. A Records Search Map, with a 0.5-mile search radius of the proposed project is enclosed for your reference (Attachment A).

As part of the cultural resources assessment, FCS conducted a Sacred Lands File (SLF) search with the Native American Heritage Commission (NAHC) and a California Historical Resource Information (CHRIS) search.

Subject: Proposed Soda Springs Ranch Open Space Preserve Project
Dear Chairperson Campbell:

FirstCarbon Solutions (FCS) is is preparing a Phase I Cultural Resources Assessment (PI-CRA) for the proposed Soda Springs Ranch Open Space Preserve Project, in the City of Cloverdale, California. As part of the environmental review process, we are reaching out to the tribes for any additional information that can be incorporated into our analysis.

The City of Cloverdale (City) is proposing to acquire a conservation easement to protect the property at 600 Cherry Creek Road, known as the Soda Springs Ranch Open Space Preserve. The 208.72-acre project site corresponds to the Assessor’s Parcel Number (APN) 115-220-007, -006, and -019. The project site is undeveloped and has historically been used for timber harvest, hunting, grazing, equipment storage, personal recreation, and open space. The permanent conservation of the Soda Springs Ranch Open Space Preserve (proposed project) would place a conservation easement over the project site to protect its natural resources, scenic resources, and recreational and educational resources. In the process, the City would close eight unnecessary trails, repair remaining roads to allow access to City maintenance vehicles, create three new multiuse trails, 5 picnic sites, fencing, as well as a parking area. A Records Search Map, with a 0.5-mile search radius of the proposed project is enclosed for your reference (Attachment A).

As part of the cultural resources assessment, FCS conducted a Sacred Lands File (SLF) search with the Native American Heritage Commission (NAHC) and a California Historical Resource Information (CHRIS) search. The results of the SLF records search were positive for any known cultural resources within the project boundaries.

We are still awaiting the CHRIS records search results. The NAHC suggested you might be able to provide further information regarding potential historic or cultural resources in proximity or relation to the proposed project. We would greatly appreciate your input.

Subject: Proposed Soda Springs Ranch Open Space Preserve Project
Dear Robert:

FirstCarbon Solutions (FCS) is is preparing a Phase I Cultural Resources Assessment (PI-CRA) for the proposed Soda Springs Ranch Open Space Preserve Project, in the City of Cloverdale, California. As part of the environmental review process, we are reaching out to the tribes for any additional information that can be incorporated into our analysis.

The City of Cloverdale (City) is proposing to acquire a conservation easement to protect the property at 600 Cherry Creek Road, known as the Soda Springs Ranch Open Space Preserve. The 208.72-acre project site corresponds to the Assessor’s Parcel Number (APN) 115-220-007, -006, and -019. The project site is undeveloped and has historically been used for timber harvest, hunting, grazing, equipment storage, personal recreation, and open space. The permanent conservation of the Soda Springs Ranch Open Space Preserve (proposed project) would place a conservation easement over the project site to protect its natural resources, scenic resources, and recreational and educational resources. In the process, the City would close eight unnecessary trails, repair remaining roads to allow access to City maintenance vehicles, create three new multiuse trails, 5 picnic sites, fencing, as well as a parking area. A Records Search Map, with a 0.5-mile search radius of the proposed project is enclosed for your reference (Attachment A).

As part of the cultural resources assessment, FCS conducted a Sacred Lands File (SLF) search with the Native American Heritage Commission (NAHC) and a California Historical Resource Information (CHRIS) search. The results of the SLF records search were positive for any known cultural resources within the project boundaries.

We are still awaiting the CHRIS records search results. The NAHC suggested you might be able to provide further information regarding potential historic or cultural resources in proximity or relation to the proposed project. We would greatly appreciate your input.

Please note that this letter is a request for information pertaining to a cultural resources assessment and is not notification of a project under Senate Bill (SB) 18, Assembly Bill (AB) 52, or Section 106 of the National Historic Preservation Act.

Subject: Proposed Soda Springs Ranch Open Space Preserve Project
Dear President Russ:

FirstCarbon Solutions (FCS) is is preparing a Phase I Cultural Resources Assessment (PI-CRA) for the proposed Soda Springs Ranch Open Space Preserve Project, in the City of Cloverdale, California. As part of the environmental review process, we are reaching out to the tribes for any additional information that can be incorporated into our analysis.

The City of Cloverdale (City) is proposing to acquire a conservation easement to protect the property at 600 Cherry Creek Road, known as the Soda Springs Ranch Open Space Preserve. The 208.72-acre project site corresponds to the Assessor’s Parcel Number (APN) 115-220-007, -006, and -019. The project site is undeveloped and has historically been used for timber harvest, hunting, grazing, equipment storage, personal recreation, and open space. The permanent conservation of the Soda Springs Ranch Open Space Preserve (proposed project) would place a conservation easement over the project site to protect its natural resources, scenic resources, and recreational and educational resources. In the process, the City would close eight unnecessary trails, repair remaining roads to allow access to City maintenance vehicles, create three new multiuse trails, 5 picnic sites, fencing, as well as a parking area. A Records Search Map, with a 0.5-mile search radius of the proposed project is enclosed for your reference (Attachment A).

As part of the cultural resources assessment, FCS conducted a Sacred Lands File (SLF) search with the Native American Heritage Commission (NAHC) and a California Historical Resource Information (CHRIS) search. The results of the SLF records search were positive for any known cultural resources within the project boundaries.

We are still awaiting the CHRIS records search results. The NAHC suggested you might be able to provide further information regarding potential historic or cultural resources in proximity or relation to the proposed project. We would greatly appreciate your input.
