Subject: Biological Resources Constraints Assessment for the City of San Carlos Fuel Management Project, San Carlos, San Mateo County, California

Dear Ms. Newby:

At the request of the City of San Carlos, Dudek conducted a biological constraints assessment for the proposed Fuel Management Project (project) that includes four distinct public parks in the City of San Carlos, San Mateo County, California: Big Canyon Park, Crestview Park, Eaton Park, and Highlands Park (Figures 1 and 2).

The currently proposed project would entail a series of vegetation management activities that will abate hazardous vegetation in the four city parks. These parks are largely undeveloped with walking trails that intersect the landscape. Specific goals of the vegetation management project include the following: (1) conduct targeted fuel reduction treatments using hand crews, masticators, track chippers, herbicides, and herbivory to reduce highly combustible underbrush and chaparral within the defensible space zone of adjacent private ownerships, (2) create strategic fuel breaks using hand crews, masticators, track chippers, and herbivory to reduce highly combustible underbrush and chaparral along access roads and ridgelines, and (3) remove dead/diseased and non-native trees as part of a comprehensive fuel reduction effort.

As part of the assessment, a reconnaissance-level field survey was conducted to identify and characterize existing biological conditions within the project site including the nature and extent of both common and sensitive natural vegetation communities, wetlands and other aquatic features potentially under the jurisdiction of state and federal resource agencies, and the potential for special-status and animal to occur. Based on the field survey as well as on a review of appropriate literature and biological databases, potential constraints to proposed fuel management from on-site biological resources were identified.

This report provides a description of the project sites, a summary of the proposed project and purpose, methodology and results of the review of available database and literature searches as well as the field survey, and a discussion of potential constraints posed by biological resources to project implementation. Suggested measures and actions to avoid and/or minimize these constraints are also provided. Site Locations and Description

The project discussed herein consists of four sites: Big Canyon Park, Crestview Park, Eaton Park, and Highlands Park in the City of San Carlos, California (Figure 1). Combined, the four portions of the project site consist of approximately 131.4 acres. The four parks are maintained and operated by the City of San Carlos and located east

of Interstate 280. From Interstate 280, the Big Canyon, Crestview, and Eaton Parks may be accessed via Crestview Drive and Brittan Avenue within the residential neighborhood of Crestview. Highlands Park may be accessed via Melendy Drive within the residential Beverly Terrace neighborhood. The location data for each site is provided in Table 1 and shown in Figure 1.

The project sites are located west of the Mt. Diablo Meridian and are all located within the “Woodside, CA” U.S. Geological Survey (USGS) 7.5-minute quadrangle. The project sites are characterized generally as undeveloped public city parks adjacent to residential neighborhoods.

Geography and Soils

All four sites are generally located east of the Pulgas Ridge Open Space Preserve in San Carlos, California. Terrain is variable within each site and ranges from hilly to flat. Elevations of the four parks range from approximately 220 feet to 700 feet, National Geodetic Vertical Datum.

Specific soil data is described for each project site in Table 2 and Figure 3, and the soil types are described in more detail below.

Table 2. Soil Data Project Site USDA Soils Types Big Canyon Park Fagan loam, 15 to 50 percent slopes; Maymen gravelly loam, 30 to 50 percent slopes; Urban land-Orthents, cut and fill complex, 5 to 75 percent slopes Crestview Park Orthents, cut and fill, 0 to 15 percent slopes; Urban land-Orthents, cut and fill complex, 5 to 75 percent slopes Eaton Park Los Gatos loam, 30 to 75 percent slopes, MLRA 15; Orthents, cut and fill-Urban land complex, 5 to 75 percent slopes; Urban land-Orthents, cut and fill complex, 5 to 75 percent slopes Highlands Park Orthents, cut and fill, 0 to 15 percent slopes; Orthents, cut and fill-Urban land complex, 5 to 75 percent slopes; Urban land; Urban land-orthents, cut and fill complex, 5 to 75 percent slopes Source: USDA 2019.

Fagan Series Soils. Fagan series soils consists of deep, well-drained soils that are of a very high run-off class derived from weathered sandstone and shale, typically found in hill landforms (USDA 2019).

11719 2 April 2019 Ms. Amy Newby Subject: Biological Resources Constraints Assessment for the City of San Carlos Fuel Management Project, San Carlos, San Mateo County, California

Maymen Series Soils. Maymen series soils consists of shallow, somewhat excessively drained soils that formed in residuum weathered from shale, schist, greenstone, sandstone, and conglomerate, typically found in mountain/hill landforms (USDA 2019).

Urban land-Orthents Series Soils. Urban land-Orthents series soils are well drained and primarily occur in the surrounding developed areas of the parks (USDA 2019).

Los Gatos Series Soils. Los Gatos series soils are well drained with a very high run-off class and are members of the fine-loamy, mixed, mesic of Typic Agrixerolls (USDA 2019). This soil type is derived from weathered sedimentary rock, and typically has brown, light clay loam, granular, slightly acid A1 horizons, brown and yellowish red, slightly and medium acid clay loam and gravelly clay loam Bt horizons over sandstone bedrock (USDA 2019).

Drainage refers to the frequency and duration of periods when the soil is saturated with water. The above soil types are non-hydric, although hydric inclusions may occur. The soil types on site are not known to support edaphic special status plant species (i.e., the soils of the site are neither serpentine nor alkaline).

Hydrology

The project sites vary in elevation from approximately 220 feet above mean sea level at Eaton Park to 700 feet above mean sea level at Crestview Park. Crestview and Highland parks do not contain wetland or waterways and are not hydrologically connected to any major waterways or bodies of water, and do not contain features, such as established banks and wetland or riparian vegetation, that would fall under jurisdictional waters of the United States.

Big Canyon Park and Eaton Park contain hydrological features. These features are defined by the steep terrain throughout the two parks, where unnamed ephemeral drainages intersect the properties. The ephemeral drainages contain distinct beds and banks and were flowing lightly during the time of the survey, during the height of the 2019 rain season. No deep-plunge pools (>6 inches in depth) were observed in the drainages. Ephemeral drainages capture and channel rainwater in the parks to the stormwater system of the surrounding neighborhoods. This water enters an unnamed creek to the east of the two parks, which then channels water northeast to the San Francisco Bay, which is a traditional navigable water, as defined by the U.S. Army Corps of Engineers (ACOE). Thus, the drainages on site are potentially jurisdictional features. Preliminary Site Evaluation

The surveys were conducted on foot to visually cover each of the four project sites. Aerial photography with an overlay of the project boundaries was utilized to map the vegetation communities and record any special-status or sensitive biological resources while in the field. Data regarding biological and jurisdictional resources present within the project sites was obtained through a review of pertinent literature and field reconnaissance. The results of the preliminary site evaluation are described in detail below.

Special-Status Species

Special-status biological resources present or potentially present on the project site were identified through a literature and database search using the following sources: US Department of Agriculture soil series maps (USDA

11719 3 April 2019 Ms. Amy Newby Subject: Biological Resources Constraints Assessment for the City of San Carlos Fuel Management Project, San Carlos, San Mateo County, California

2019) (Figure 3); the U.S. Fish and Wildlife Service (USFWS) Information, Planning and Conservation (IPaC) Trust Resource Report (USFWS 2019); the CDFW California Natural Diversity Database (CNDDB) (CDFW 2019); and the California Native Plant Society (CNPS) online Inventory of Rare, Threatened, and Endangered (CNPS 2019a).

Searches of the above-referenced databases were completed for the Woodside and eight surrounding U.S. Geological Survey 7.5-minute quadrangles: San Mateo, Half Moon Bay, Palo Alto, Montara Mountain, San Gregorio, La Honda, Mindego Hill and Redwood Point. CNDDB search results within 2 miles of the project site were overlain on aerial imagery to assess proximity of known occurrences to the project site (Figure 4).

The literature and database review focused on the potential for special-status vegetation communities and/or species to occur on or immediately adjacent to the project site. For this report, special-status plant and animal species are defined as those that are (1) listed, proposed for listing, or candidates for listing as Threatened or Endangered under the federal Endangered Species Act; (2) listed or candidates as Threatened or Endangered for listing under the California Endangered Species Act; (3) a state fully protected species; (4) a California Department of Fish and Wildlife (CDFW) Species of Special Concern; or (5) a species listed on the CNPS Inventory of Rare and Endangered Plants with a California Rare Plant Rank (CRPR) of 1A, 1B, 2A, or 2B. Special-status vegetation communities are those communities identified as high priority for inventory in the List of Vegetation Alliances and Associations (CNPS 2019a) by a state rarity ranking of S1, S2, or S3.

Following review of these resources, Dudek determined the potential for each species to occur within the site based on a review of vegetation communities and available land cover types, soils, and elevation preferences, as well as the known geographic range of each species (Attachments 1 and 2). For example, if the site is within the elevation range of a particular plant species, but a specific soil type for the species is not present, the species is considered to have low potential to occur on the site. Also, species were not expected to occur when the site was clearly outside of the known geographic range of the species.

Field Reconnaissance and Methods

Biological reconnaissance surveys were conducted by Dudek biologists Laura Burris and Emily Scricca on March 7, and March 11, 2019. Because one of the purposes of the site visits was to identify the potential of on-site habitats to support special-status plant and/or wildlife species, no focused presence/absence surveys for such species were conducted. The surveys included walking the project sites where access was possible and conducting visual surveys. Objectives during the surveys included mapping vegetation communities, land cover types encountered, and potentially jurisdictional wetlands or waters of the U.S., and assessing the potential for special-status species to occur within the project sites.

Vegetation Community and Land Cover Mapping

The surveys were conducted on foot to visually cover each of the four project sites. Aerial photography with an overlay of the project boundaries was utilized to map the vegetation communities and record any special-status or sensitive biological resources while in the field.

Flora

Plant species encountered during the field surveys that were able to be identified were recorded directly into a field notebook. Common and scientific names for plant species with a California Rare Plant Rank (CRPR, formerly CNPS List) follow the CNPS On-Line Inventory of Rare, Threatened, and Endangered Plants of California (CNPS 2019a). Unknown plant species were either photographed or collected when the population could sustain collection, and identified at the lab. A list of plant species observed on the sites is presented in Attachment 3.

Fauna

Wildlife species detected during the field surveys by sight, calls, tracks, scat, or other signs were recorded directly into a field notebook. The sites were scanned with and without binoculars to aid in the identification of wildlife. In addition to species actually detected during the surveys, expected wildlife use of the sites was determined by known habitat preferences of local species and knowledge of their relative distributions in the area. A list of wildlife species observed on the sites is presented in Attachment 4.

Jurisdictional Wetlands

Dudek conducted a constraints-level analysis for potentially jurisdictional waters and wetlands based on criteria provided by the following agencies:

• Waters of the U.S., including wetlands, under the jurisdiction of the ACOE pursuant to Section 404 of the federal Clean Water Act. • Wetlands under the jurisdiction of the Regional Water Quality Control Board (RWQCB) pursuant to Section 401 of the Clean Water Act and the Porter-Cologne Act. • Wetlands under the jurisdiction of CDFW, pursuant to Section 1602 of the California Fish and Game Code.

Pursuant to the federal Clean Water Act, ACOE- and RWQCB-jurisdictional areas include those supporting all three wetlands criteria described in the ACOE manual: hydric soils, hydrology, and hydrophytic vegetation. Areas regulated by the RWQCB are generally coincident with the ACOE, but may also include isolated features that have evidence of surface water inundation pursuant to the state Porter Cologne Act. These areas generally support at least one of the three ACOE wetlands indicators but are considered isolated through the lack of surface water hydrology/connectivity downstream. The extent of CDFW-regulated areas typically include areas supporting a predominance of hydrophytic vegetation (i.e., 50% cover or greater) where associated with a stream channel.

Specifically, Dudek performed a constraints-level wetland assessment within the project sites, reviewed current and historical aerial photography, and then identified potentially jurisdictional features based on aerial signatures and field observations. Because the focus of this assessment was to identify areas potentially under the jurisdiction of these resource agencies, no formal protocol-level jurisdictional delineation was conducted at this time. Any water and drainage features and associated vegetation was assessed and marked directly on aerial imagery in the field. Dudek geographic information systems (GIS) specialists mapped observed and documented biological and wetland resources on aerial imagery and provided figures using ArcGIS software.

Results

The quantification of biological resources described below pertains to habitats and species present within the project sites only. No off-site areas are included in this analysis since these areas were not evaluated as part of the assessment. Representative photographs of the proposed project sites are depicted in Attachment 5.

Vegetation Communities and Land Cover Types

The majority of the sites contained coast live oak woodland with hillsides lined with chamise chaparral and California sage brush scrub (Figure 4). Areas of sparse vegetation were dominated mostly by annual grassland, and some parks contained developed, manicured park ground with landscaped plantings and eucalyptus groves. These land cover types are described for each project site in detail below.

Big Canyon Park. The Big Canyon Park project site is comprised of approximately 23 acres of coast live oak woodland. This vegetation community most closely resembles coast live oak (Quercus agrifolia) woodland alliance as defined by The Manual of California Vegetation, Online Edition (CNPS 2019b). The coast live oak woodland vegetation community within the project site is dominated by coast live oak, with California bay laurel (Umbellularia californica) as a secondary canopy species and an understory of dense shrub containing poison oak (Toxicodendron diversilobum), California buckeye (Aesculus californica), toyon (Heteromeles arbutifolia) and various herbaceous and annual grassland species. Bay laurel becomes codominant in the coast live oak woodland alongside the ephemeral drainages throughout the Big Canyon Park. The stands of oak woodland forest found within Big Canyon Park are mature tree stands with a naturalized and well-established canopy and understory. As such, the habitat value throughout the project site is overall of good quality to support an abundance of wildlife species including bird species, mammals, reptiles and amphibians. Most notably, a high density of woodrat (Neotoma fuscipes) nests were observed throughout Big Canyon Park during the March 7, 2019 site visit; because these sites fall within the range of the special-status San Francisco dusky-footed woodrat, these nests are likely protected and are discussed further below.

Stands of chamise chaparral habitat occur primarily along the south-facing slopes of Big Canyon Park and comprises approximately 17 acres of the project site (Figure 4). This chamise chaparral habitat most closely resembles chamise–black sage (Adenostoma fasciculatum–Salvia mellifera) chaparral shrubland alliance (CNPS 2019b). The stands of chamise chaparral throughout the site are co-dominated by chamise and black sage with other species including coyote brush (Baccharis pilularis), buck brush (Ceanothus cuneatus) and California sagebrush (Artemisia californica). These areas consist largely of mature, naturalized stands with a variety of native plant species and few non-native shrub species occurring within this habitat type. On site, the chamise chaparral has a high cover of poison oak and black sage. Non-native plant species which were observed adjacent to or within the project site included small stands of French broom (Genista monspessulana) and Scotch broom (Cytisus scoparius) along more disturbed areas adjacent to the pedestrian trails. Since the chaparral stands are well established and of good habitat quality, it is expected that a diversity of birds, mammals and reptiles are supported in this habitat type. Bird species observed during the March 7, 2019 site visit within the chamise chaparral community was consistent with what can be expected in mature chaparral stands: California scrub jay (Aphelocoma californica), Steller’s jay (Cyanocitta stelleri), and spotted towhee (Pipilo maculatus). Other resident and migratory hawks, owls, songbirds, and woodpeckers, particularly those adapted to more urbanized settings, are also known to use transitional areas within and adjacent to the project site for nesting, food, and cover (CDFW 2019).

Stands of California sagebrush scrub occur primarily along the western and northern-facing slopes of Big Canyon Park and comprises approximately 9 acres of the project site (Figure 4). This coastal sage habitat is dominated by black sage and California sagebrush, with patchy tree species present throughout.

The Big Canyon Park project site includes approximately 7 acres of California annual grassland (Figure 4). The grassland is dominated by non-native, naturalized grassland species such as slender wild oats (Avena fatua), and stands of various non-native thistle species such as yellow star thistle (Centaurea solstitialis) and Maltese star- thistle (Centaurea melitensis), which were observed during the March 7, 2019 site survey. The California annual grassland community species composition is typical of what is found throughout much of the Bay Area, with introduced grass species dominating the landscape. Annual grassland community may support a wide range of bird, mammal and reptile species but displaces many of the native herbaceous flowering plants and grasses. Birds of prey such as white-tailed kite (Elanus leucurus) rely on grassland habitat for foraging/hunting.

The Big Canyon Park project site is bounded on the north, east, and west by residential development, and on the south by Eaton Park.

Crestview Park. The Crestview Park project site includes approximately 1 acres of landscape plantings on the northern boundary of the park (Figure 4). This area is dominated by Tasmanian bluegum (Eucalyptus globulus) and ornamental cypress (Cupressus sp.). The hillside in this area also contained coast live oak, Acacia (Acacia sp.), and shining willow (Salix lasiandra). Shrubs in the Landscape plantings include French and scotch broom, and coyote brush (Baccharis pilularis).

On the western edge of Crestview Park is approximately 1 acre of Eucalyptus Grove, which is dominated by Tasmanian bluegum (Figure 4). These trees are generally naturalized on uplands or bottomlands and adjacent to stream courses, lakes, or levees (CNPS 2019b).

On the southern edge of Crestview Park is approximately 1 acre of Coast live oak woodland. This area is dominated by coast live oak with non-native, naturalized grassland species such as purple pampas grass (Cortaderia jubata) which was observed during the March 7, 2019 site survey.

Wildlife species such as gray squirrels, chestnut-back chickadees, golden-crowned sparrows, spotted towhees and dark- eyed juncos may inhabit these habitats. A Townsend’s warbler was observed foraging among the coast live oak canopy during the March 7 survey. Several botta’s pocket gopher burrows were also observed in the grassland patches.

The Crestview Park project site is shaped around a developed baseball field and is bounded by residential development in all four cardinal directions.

Eaton Park. The Eaton Park project site is comprised of approximately 50 acres of coast live oak woodland (Figure 4). Descriptions of this habitat type are provided above in the Big Canyon Park project site description. A high density of San Francisco dusky-footed woodrat nests were observed throughout Eaton Park during the March 11, 2019 site visit.

Stands of chamise chaparral habitat occur primarily along the south-facing slopes of Eaton Park and comprises approximately 1.5 acres of the project site, and California sage brush scrub occur primarily along the western and

11719 7 April 2019 Ms. Amy Newby Subject: Biological Resources Constraints Assessment for the City of San Carlos Fuel Management Project, San Carlos, San Mateo County, California

northern-facing slopes totaling 4 acres (Figure 4). Descriptions of both habitat types are provided above in the Big Canyon Park project site description.

The Eaton Park project site includes approximately 6 acres of California annual grassland (Figure 4). The grassland is dominated by non-native, naturalized grassland species similar to those found in the Big Canyon Park project site. Small clusters of native perennial bunch grass were observed along the trail side of Eaton Park where annual grassland had not encroached.

There is a small stand of Eucalyptus Grove on the western end of Eaton Park totaling approximately 2 acres. South of this grove was a hillside dominated by Landscape Plantings, approximately 2 acres, containing plant species such as scotch broom, poison oak, purple leaf plum (Prunus cerasifera).

Numerous bird species are expected to inhabit areas throughout Eaton Park for foraging and breeding. Nuttall’s woodpeckers and Acorn woodpeckers were heard in the canopies during the March 11 survey, while species such as lesser goldfinch, dark-eyed junco, yellow-rumped warbler, spotted towhee, and black phoebe were observed in the mid canopy. Tree swallows were observed on the hillsides. A red-tailed hawk and red-shouldered hawk was observed flying over the park during the March 11 survey. Black-taileddeer scat and several deer trails were present.

The Eaton Park project site is bounded on the north by Big Canyon Park, and residential development to the south, east, and west.

Highlands Park. The Highlands Park project site is comprised almost entirely of Eucalyptus grove, totally approximately 4 acres (Figure 4). The Eucalyptus Grove at this site contained Tasmanian bluegum dominating the canopy with also some coast live oak present. Plantings of Aleppo pine (Pinus halapensis) are present on the slope just west of the playing fields at Highlands Park. Stands of French broom, Scotch broom, and poison oak were observed along more disturbed areas adjacent to the pedestrian trails. There is also approximately 1.5 acres of Landscaped Plantings along the eastern edge of Highlands Park (Figure 4). Bird species expected to occur throughout this park include dark-eyed junco, California towhee, chestnut-backed chickadee, and Anna’s hummingbird. American crows were observed with nesting materials during the March 7 survey.

The Highlands Park project site is bounded on the north, south, and west by residential development, and on the east by public sports fields.

Aquatic Habitats and Jurisdiction Wetlands and Waters

Only Big Canyon Park and Eaton Park contain hydrological features. These aquatic habitats are limited to ephemeral streams, and wetland delineations have not been completed for these sites.

Plants and Wildlife

A total of 86 species of vascular plants were recorded during the site surveys (Attachment 3); of the 86 species observed, 56 were native to California and 30 were nonnative.

Twenty-nine wildlife species or their sign were observed during the field surveys: gray squirrel (Sciurus griseus), Anna’s hummingbird (Calypte anna), California gull (Larus californicus), red-shouldered hawk (Buteo lineatus), red-

tailed hawk (Buteo jamaicensis), acorn woodpecker (Melanerpes formicivorus), Nuttall’s woodpecker (Dryobates nuttallii), northern flicker (Colaptes auratus), black phoebe (Sayornis nigricans), Steller’s jay (Cyanocitta stelleri), California scrub-jay (Aphelocoma californica), American crow (Corvus brachyrhynchos), common raven (Corvus corax), tree swallow (Tachycineta bicolor), chestnut-backed chickadee (Poecile rufescens), bewick’s wren (Thryomanes bewickii), ruby-crowned kinglet (Regulus calendula), American robin (Turdus migratorius), house finch (Haemorhous mexicanus), lesser goldfinch (Spinus psaltria), spotted towhee (Pipilo maculatus), California towhee (Melozone crissalis), golden-crowned sparrow (Zonotrichia atricapilla), dark-eyed junco (Junco hyemalis), yellow- rumped warbler (Setophaga coronata), Townsend’s warbler (Setophaga townsendi), black-tailed deer (Odocoileus hemionus ) tracks and scat, coyote (Canis latrans) scat, and Botta’s pocket gopher (Thomomys bottae) burrows. Additionally, ephemeral streams in Big Canyon Park and Eaton Park likely provide habitat to amphibians and reptiles for foraging and cover.

Special-Status Species

Plants

A total of 61 special-status plants have been documented within the project USGS quadrangle or the surrounding 8 quadrangles and are listed in Attachment 1. Occurrences of special-status species within a 2-mile radius of the project site are mapped on Figure 2. Of the 61 total species documented in the project vicinity, 16 special-status plants have been identified as having moderate to high potential to occur within or adjacent to the project site. These species include San Mateo thorn-mint (Acanthomintha duttonii), Franciscan onion (Allium peninsulare var. franciscanum), bent-flowered fiddleneck (Amsinckia lunaris), Crystal Springs Fountain thistle (Cirsium fontinale var. fontinale), San Francisco collinsia (Collinsia multicolor), western leatherwood (Dirca occidentalis), fragrant fritillary (Fritillaria liliacea), Marin western flax (Hesperolinon congestum), Crystal Springs lessingia (Lessingia arachnoidea), arcuate bush-mallow (Malacothamnus arcuatus), woodland woolythreads (Monolopia gracilens), white-rayed pentachaeta (Pentachaeta bellidiflora), chaparral ragwort (Senecio aphanactis), San Francisco campion (Silene verecunda ssp. verecunda), two fork clover (Trifolium amoenum), and San Francisco owl’s clover (Triphysaria floribunda) (CDFW 2019; CNPS 2019a). The remaining 45 plant species listed in Attachment 1 are associated with unaltered grassland habitat, specific soil types, or seasonal wetlands such as vernal pools. The lack of such habitat features in the mostly naturalized landscapes within the project sites create a very low probability for the occurrence of some of these species. Thus, these species are not likely to occur within the project sites.

San Mateo thorn-mint, Crystal Springs fountain thistle, Marin western flax, arcuate bush-mallow, woodland woolythreads, chaparral ragwort, and San Francisco campion have potential to occur in chaparral habitat on site. Franciscan onion, bent-flowered fiddleneck, fragrant fritillary, Crystal Springs lessingia, white-rayed pentachaeta, two-fork clover and San Francisco owl’s-clover have potential to occur in grassland habitat on site.

Franciscan onion was documented within the northwestern section of the Eaton Park project site in 2015 by the City of San Carlos (CDFW 2019). San Francisco collinsia has been previously documented within Big Canyon Park and Eaton Park in habitats of chaparral and serpentine soils, with the most recent occurrences documented in 2017 within the park boundaries (CDFW 2019). Western leatherwood was documented in 2015 in the northern section of the Eaton Park project site within oak woodland habitat (CDFW 2019). San Mateo thorn-mint, Crystal Springs fountain thistle, Crystal Springs lessingia, and white-rayed pentachaeta have been recorded immediately south and within 2-miles of the Crestview Park project site. Fragrant fritillary, Marin western flax, and San Francisco

11719 9 April 2019 Ms. Amy Newby Subject: Biological Resources Constraints Assessment for the City of San Carlos Fuel Management Project, San Carlos, San Mateo County, California

campion have been recorded immediately south and within 2-miles of the Eaton Park project site. Arcuate bush- mallow, woodland woolythreads and chaparral ragwort have been recorded immediately north and within 2-miles of the project site. These observations are shown in Figure 4.

Several San Francisco collinsia plants were noted during the March 7, 2019 site survey at the Big Canyon Park project site in the same location the species was previously documented within the CNDDB (Figure 5). The collinsia was young and did not yet have identifying characteristics but coincided with previously documented occurrences. Western leatherwood was noted during the March 11, 2019 site survey at the Eaton Park project site in the same location the species was previously documented within the CNDDB, in woodland habitat adjacent to drainages on site. No other special-status plant species were discovered during the March 2019 site surveys.

The surveys did not coincide with the appropriate blooming periods for the above listed plants. The timing of the surveys made detection unlikely for the remaining species with potential to occur.

Wildlife

A total of 38 special-status wildlife species were identified within the project USGS quadrangle and surrounding 8 quadrangles (Attachment 2). Of the 38 species identified, three have potential to occur on site based on vegetation communities, soils, and previously documented occurrences in the vicinity and are discussed further below. The remaining 35 species listed in Attachment 2 were excluded from further consideration due to the lack of suitable breeding, nesting, migration, or estivation habitat observed during the March 7 and March 11, 2019 site visits. Many of these species are associated with specific habitat types such as wetlands with open water features, open flat grasslands with minimal to no urban development present.

Special-status bat species identified in proximity to the project site included pallid bat (Antrozous pallidus) and Townsend’s big-eared bat (Corynorhinus townsendii).These species may be temporally present in the project area; however, the site does not provide adequate maternity roost habitat and occurs within a disturbance area with regular human activity. The pallid bat is very sensitive to disturbance of roost sites; therefore, not likely to occur within the project site. The Townsend’s bat roosts in limestone caves and lava tubes, which are habitats that are not found within the project area.

Species with low potential to occur on site include California (CA) red-legged frog (Rana draytonii), and San Francisco garter snake (Thamnophis sirtalis tetrataenia). CA red-legged frog is known to occur west of Highway 280, approximately 1.6-miles from the Crestview Park project area. No CA red-legged frog was observed during the site visits with no suitable breeding or upland habitat identified during the site visits. San Francisco garter snake is known to occur approximately 1.7-miles from the Big Canyon Park project site in adjacent open space/undeveloped areas. San Francisco garter snake is highly associated with wetland vegetation and open water, with CA red-legged frog as a main prey item. No observations of individuals, their prey item or suitable habitat was observed during the site visits.

Other special-status species with moderate or high potential to occur on the project site are white tailed kite (Elanus leucurus), the San Francisco dusky-footed woodrat (Neotoma fuscipes annectens), and Bay checkerspot butterfly (Euphydryas editha bayensis). These species are discussed in further detail, below.

White-tailed Kite. The white-tailed kite is a California Fully Protected species. It is commonly associated with certain types of agriculture areas (Grinnell and Miller 1944). It also generally occurs in low-elevation grassland, wetland,

11719 10 April 2019 Ms. Amy Newby Subject: Biological Resources Constraints Assessment for the City of San Carlos Fuel Management Project, San Carlos, San Mateo County, California

oak woodland, low shrub, open woodlands, or savannah habitats. It is tolerant of moderate disturbance, such as occurs near residential subdivision developments. This species also uses fencerows and irrigation ditches (with residual vegetation). Riparian areas adjacent to open space areas are typically used for nesting, where kites prefer dense, broadleafed deciduous trees for nesting and night roosting (Brown and Amadon 1968). They also nest in young redwoods and mid-sized Douglas firs in .

Trees in the project sites provide potentially suitable nesting habitat for this species and open, grassy areas provide suitable foraging habitat. This species was not observed during the March 7 and 11, 2019 site surveys; however, there is potential for it to utilize trees in the project sites for nesting.

San Francisco Dusky-footed Woodrat. San Francisco dusky-footed woodrat is a subspecies of the more widely distributed dusky footed woodrat, and the subspecies is considered a Species of Special Concern by CDFW.

The San Francisco dusky-footed woodrat is a small-sized rodent that builds nests made of sticks, typically at the base of trees and shrubs, but sometimes in the low to mid-level canopy of a tree. This species prefers forested habitat with a moderate canopy and dense undergrowth, particularly on the upper banks of riparian forests or within poison oak- dominated shrublands. The dusky-footed woodrat feeds on a variety of woody plants, fungi, flowers and seeds. Research has indicated that a single nest may be used by many generations over the period of several years or more (Murray and Barnes 1969). The project sites are located within oak woodland and riparian habitats with a dense understory dominated by poison oak and other shrub vegetation, which are the preferred habitat for this species.

During the March 7 and 11, 2019 site surveys, numerous woodrat nests were observed on the project sites in Big Canyon and Eaton parks. The nests that were inspected contained scat and food debris at the entrances, which indicates some degree of occupation by woodrats. Several nests appeared to be somewhat dilapidated, and others were located within thickets of poison oak and were not able to be inspected. It is anticipated that the majority of these nests are active, or were active at one time, based on the suitability of habitat and the presence of food items throughout the project sites.

Bay Checkerspot Butterfly. Bay checkerspot butterfly is known to occur in Edgewood Regional Park, which is approximately 1.0-mile south of the Eaton Park project area. A summary description providing further information is below. Bay checkerspot butterfly is a federally threatened species under the Federal Endangered Species Act. It is a medium-sized butterfly with a wing span of a little more than 2-inches and black bands along the wing veins contrasting with bright red, yellow and white spots on the dorsal surface of the wings. The range of this species is limited to the San Francisco Bay Area with its current range reduced to six known core areas-one on the San Francisco peninsula, one in San Mateo County and four in Santa Clara County. Bay checkerspot are found in open grassland habitats with shallow, serpentine-derived soils which support the host plants on which the larvae feed. The primary host plant is dwarf plantain (Plantago erecta), with Indian paintbrush ( exserta spp. exserta) acting as a secondary host plant. Adults emerge in the early spring between late February and early May to lay eggs during the flight season. Larvae hatch from the eggs in about ten days then enter into a diapaus stage in which they enter a period of dormancy. This diapause ends with the onset of the next rainy season and the germination of the host plant. The larvae then resume feeding to complete their development.

No host plants were observed during the March 7 and March 11, 2019 site surveys; however, the timing of the surveys limited the ability to identify flowering host plants. The open grassland habitat found throughout the project sites is dominated by introduced European grasses with minimal patches of native grassland and high cover of

11719 11 April 2019 Ms. Amy Newby Subject: Biological Resources Constraints Assessment for the City of San Carlos Fuel Management Project, San Carlos, San Mateo County, California

thatch. The limited distribution of native grassland on the project site makes it unlikely this species is present. Additionally, grazing in areas containing dense thatch would likely increase native forb germination and recruitment, increasing the likelihood that these areas will become more suitable for this species’ host and nectar plants (Jain 2015; Weiss 2001).

Nesting and Migratory Birds

Although no special-status bird species were observed during the March 7 and March 11, 2019 field surveys, all native birds in California are protected by the federal Migratory Bird Treaty Act (MBTA) of 1918 and Sections 3503 and 3503.5 of the California Fish and Game Code which respectively protect active nests and eggs of any bird and individuals and nests/eggs of raptors. The trees and landscaping within and adjacent to the project sites provide suitable nesting habitat for a number of native local and migratory bird species. For example, California thrasher (Toxostoma redivivum), Nuttall’s woodpecker (Picoides nuttallii), oak titmouse (Baeolophus inornatus)), song sparrow (Melospiza melodia), spotted towhee (Pipilo maculatus clementae), and wrentit (Chamaea fasciata) are year-round residents in the region that may breed on the project site based on presence of habitat. Allen’s hummingbird (Selasphorus sasin) and rufous hummingbird (Selasphorus rufus) are summer migrants that may breed on the project site from late February through August.

Sensitive Natural Communities

The vegetation communities on site all have state rarity rankings of S4 or higher; thus, no sensitive natural communities occur on site and no impacts to sensitive natural communities are anticipated as a result of project activities.

Potentially Jurisdictional Wetlands and Waters

Due to the ephemeral nature of the hillside drainages at Big Canyon and Eaton parks, which capture and channel rainwater to the stormwater system of the surrounding neighborhoods, which eventually channel water northeast to the San Francisco Bay, the drainages in these parks are potentially jurisdictional features (80 FR 37054–37127; Figure 4). Additionally, discharges to other “waters of the state” remain subject to state regulation under the Porter- Cologne Water Quality Control Act.

Wildlife Corridors and Habitat Linkages

Wildlife corridors are linear features that connect large patches of natural open space and provide avenues for the migration of animals. Habitat linkages are small patches that join larger blocks of habitat and help reduce the adverse effects of habitat fragmentation; they may be continuous habitat or discrete habitat islands that function as stepping stones for wildlife dispersal.

Ephemeral drainages with riparian cover such as those within the Big Canyon and Eaton parks project sites serve as local movement corridors that connect foraging, breeding, and cover habitat for resident wildlife species. Additionally, because these riparian areas are surrounded by developed areas, they may also provide essential habitat linkages between fragmented segments of natural habitat.

11719 12 April 2019 Ms. Amy Newby Subject: Biological Resources Constraints Assessment for the City of San Carlos Fuel Management Project, San Carlos, San Mateo County, California

Because the project sites are situated within fragmented habitat within a suburban setting, the ephemeral drainages provide moderately functional wildlife corridors and habitat linkages. However, the proposed short-term fuel management activities would not impede local or seasonal movements of animals through the surrounding habitat. Constraints Analysis

This section addresses potential constraints to implementation of the project due to special-status biological and wetland resources present or potentially present within or immediately adjacent to the project site.

Special-Status Plant and Wildlife Species

Several special-status plant species were identified on site during the reconnaissance-level surveys, western leatherwood and, potentially, San Francisco collinsia. Ground disturbing activities have the potential to adversely affect special-status plant species, and trimming of woody species may result in direct impacts to western leatherwood. To protect special-status plant species, a survey will be conducted prior to ground-disturbing activities with heavy equipment and prior to vegetation management adjacent to identified western leatherwood trees by a qualified botanist at the appropriate period when these species are evident and identifiable to identify the locations of special-status plant species within the treatment areas. If species are found within the selected treatment areas during surveys, the individuals or populations will be flagged with high-visibility flagging and completely avoided. If avoidance is not feasible, an appropriate mitigation plan will be developed and implemented. The mitigation plan will include translocation and propagation methods, monitoring requirements, and success criteria based on the identified species.

San Francisco Dusky-footed Woodrat. As discussed above, several woodrat nests were identified during the March 7, and March 11, 2019 site surveys, occurring throughout much of the project site. Based on the project location, they are presumed to belong to the San Francisco subspecies. If project implementation were to occur near an active nest, vegetation removal and other human activities associated with the project could adversely affect these nests and woodrats within them. With implementation of the following measures, no impacts to this species are anticipated to occur as a result of project activities.

• Woodrat nests will not intentionally be destroyed. Where feasible, an exclusion buffer of at least 10 feet from nests shall be established to avoid moving or bumping the nests or the logs or branches on which the nests rest. Screening for houses will be left in place provided the integrity of the fuel break is not compromised. • If establishing a buffer and avoiding the nests is not feasible, the nests shall be dismantled and the nesting material moved to a new location outside the project’s impact areas so that it can be used by woodrats to construct new nests. Prior to nest deconstruction, each active nest shall be disturbed by a qualified wildlife biologist to the degree that all woodrats leave the nest and seek cover out of the impact area. Whether the nest is on the ground or in a tree, the nest shall be slightly disturbed (nudged) to cause the woodrats to flee. For tree nests, a tarp shall be placed below the nest and the nest dismantled using hand tools (either from the ground or from a lift). The nest material shall then be piled at the base of a nearby tree or large shrub outside of the impact area.

Bay Checkerspot. Grassland habitat within the project site is largely overgrown with non-native European grasses and habitat for Bay checkerspot host plants and nectar plants is limited. Thus, the likelihood that this species is

11719 13 April 2019 Ms. Amy Newby Subject: Biological Resources Constraints Assessment for the City of San Carlos Fuel Management Project, San Carlos, San Mateo County, California

present on site is low. Additionally, grazing activities will reduce the amount of non-native grass thatch. The reduction in thatch will likely aid in the germination of native forbs, including host plant species for this species. Thus, the fuels management activities will likely be beneficial for this species.

White tailed kite, and Nesting and Migratory birds. Impacts could occur through direct destruction of nesting habitat or nests, or by reducing reproductive success at nests due to increased noise, vibration, and human presence during hand clearing or mastication should these activities take place during the nesting bird season. Nesting bird activity was observed during the March 7 and March 11, 2019 site visits. American crows at the Highlands Park project site were observed carrying nesting materials and displaying courtship behavior. Anna’s hummingbirds throughout the project sites were displaying courtship behavior. Implementation of the following measures is expected to avoid/minimize potential impacts to nesting birds:

• If possible, fuel management using goat and mastication work shall be conducted outside of the nesting bird season (February 1 through August 30, depending on species) to avoid impacts to nesting birds. • If construction will occur within the nesting season, a pre-construction nesting bird survey of all potential nest habitat within the fuel management areas, including a 100-foot buffer for passerine species and a 250-foot buffer for raptors, shall be completed by a qualified biologist no earlier than 10 days prior to beginning fuel management during the nesting season to determine if any native birds are nesting on or near the site. If there is a lapse between the survey time and initiation of work activities of 10 days or greater, the nesting bird survey should be repeated. • If active nests are encountered at any time during fuel management activities, work in that area will stop and a qualified biologist will determine a suitable avoidance buffer from the nest based on work activity and species. The nest(s) and associated avoidance buffers will be flagged by the biologist based on species, location and planned fuel management activity. These nests should be avoided until the chicks have fledged and the nests are no longer active, as determined by the biologist. Conclusions

With implementation of the measures outlined herein, biological resources on the project sites should not significantly constrain the proposed fuels management.

City of San Carlos Fuel Management Project

Addendum A – Project Description

City of San Carlos Fuel Management Project Addendum A – Project Description

Purpose The purpose of the proposed project is to reduce hazardous fuel loads and vertical and horizontal fuel continuity within the Wildland Urban Interface (WUI) in City-owned parks located in the southwest portion of the City of San Carlos. The majority of the project area is classified by the City as a Hazardous Fire Area. The project will benefit up to 307 residential properties that directly abut the parks where proposed fuel management activities will take place, and will provide benefits to a significant number of residential structures, infrastructure, and natural resources in the surrounding area by minimizing the potential for wildfire ignition and spread. The project will also benefit responding fire agency personnel by providing defensible space areas and moderating fire behavior should a fire occur. Location and Timing The project consists of four (4) distinct parks in the City of San Carlos which can be accessed by Crestview Drive, Brittan Avenue, and Melendy Drive. Fuel reduction treatments will be used to create a mosaic of retained vegetation on up to 65.3 acres in Eaton Park, 55.3 acres in Big Canyon Park, 3.4 acres in Crestview Park, and 7.4 acres in Highlands Park (See Project Location Map). Some areas will not be treated due to the presence of cut banks, light fuel loads, steep slopes, riparian set-backs and/or access or equipment limitations. It is anticipated that this project will be conducted over a 2-year timespan, beginning during spring of 2019, and concluding prior to the end of the grant period in the fall of 2021. Project Site Description and Environmental Setting Terrain in the proposed project area is moderate to steep with slopes generally between 30 to 50 percent. Portions of the proposed project area are covered with annual grasses, extremely dense brush, and heavy concentrations of dead and down material resulting from sudden oak death and recent drought conditions. The predominant vegetation types in the project area are coast live oak woodland, chamise chaparral, and California sage brush scrub. Common shrub species include poison oak (Toxicodendron diversilobum), toyon (Heteromeles arbutifolia), California buckeye (Aesculus californica), coyote brush (Baccharis pilularis), chamise (Adenostoma fasciculatum), monkey flower (Mimulus aurantiacus), and black sage (Salvia mellifera) as well as various ceanothus (Ceanothus spp.), manzanita (Arctostaphylos spp.), and acacia (Acacia sp.) species. Common trees include coast live oak (Quercus agrifolia), California bay laurel (Umbellularia californica), Tasmanian bluegum (Eucalyptus globulus), Monterey pine (Pinus radiata), and ornamental pine (Pinus sp.) and cypress (Cupressus sp.). French broom (Genista monspessulana) is present in most locations, with significant cover found at Highlands Park. Elevation in the project area ranges from 220 to 700 feet above mean sea level. Slopes are variable, ranging from near flat (0 percent) to 100 percent, while proposed project activities will typically occur on slopes between 30 to 50 percent. The climate is Mediterranean, with warm dry summers and cool wet winters. Activities The project proposes to manage vegetation to reduce fuel loads and the horizontal and vertical continuity of surface and ladder fuels within project area through the use of hand crews, chippers, herbivory, herbicide, and masticators. Fuel management will include the treatment of grasses, forbs, brush, small live trees (<10 inches trunk diameter at breast height (DBH)), dead and dying brush and trees, and downed, dead material. The City of San Carlos will conduct outreach to educate adjacent homeowners, request right-of-entry for project area access, where necessary, and coordinate contracts to execute the proposed project. Following implementation of the proposed project, the fuel reduction sites will also require ongoing maintenance. It is anticipated that maintenance would be conducted by the City of San Carlos. Hand crews will utilize hand tools such as chainsaws, pole saws, loppers, axes, and/or weed wrenches for pulling/grubbing weeds, thinning brush, felling small diameter live trees (<10 DBH), pruning, felling dead and dying trees, and bucking material into smaller, manageable lengths. Crews will hand carry and feed cut material to staged chippers. Hand crews will also utilize hand tools such as shovels, Pulaskis, or McLeods to scrape ground fuels. The project proponent anticipates very limited availability of hand crews within the proposed project timeframe. Large diameter (>10 inches DBH) or overstory trees may be removed only if determined to be dying, or hazardous, by a

1 City of San Carlos Fuel Management Project Addendum A – Project Description

Registered Professional Forester or International Society of Arboriculture Certified Arborist. No limbs measuring 6 inches or greater in diameter will be removed from large retained oak trees. Removal of invasive species, such as French broom, will be a high priority. Chippers will be operated on existing roads, road shoulders, existing trails, and/or on stable slopes in the proposed project area. Herbicide application will be done by a Licensed Applicator according to a Pest Control Advisor’s recommendations and in accordance with the City’s Integrated Pest Management (IPM) policy. Goats or other herd animals may be used to reduce fine fuels such as annual grasses and new growth on brush and trees. Animals will be monitored and moved periodically through the project area. Animals will be contained in the project area with existing and temporary fencing, such as 3-foot high electric wire fencing supported by ½ inch ground stakes. Monitoring will ensure that grazing pressure does not result in overgrazed and denuded slopes. If the previous location of the animals is not known, or may have had known invasive species present, animals will be quarantined for a minimum of 24 hours prior to turnout. Masticators may be used where they can operate on existing roads, trails, or slopes with gradients measuring <30%, avoiding riparian areas. The objective will be to disrupt the horizontal and vertical continuity of surface and ladder fuels. A spotter will be used to inspect the ground in advance of the masticator. Brush will be treated in a mosaic pattern, leaving trees and larger brush specimens interspersed throughout the treated fuel break area for maintenance of aesthetics and visual screens. All project staging areas will be located in turnouts, parking areas, or existing clearings within or adjacent to the project area. Avoidance and Minimization Measures Consistent with the recommendations included in the Cultural Resources Inventory Report (Addendum B) and the Biological Resources Constraints Assessment (Addendum C) prepared for the project, the following measures will be implemented during the project: Cultural Resources:

• No archaeological resources were identified within the project site or immediate vicinity; however, some may be encountered during project implementation. • All crews should be alerted to the potential to encounter archaeological material. In the event that cultural resources (sites, features, or artifacts) are exposed during work activities for the proposed project, all ground disturbing work occurring within 100 feet of the find shall immediately stop until a qualified specialist, meeting the Secretary of the Interior’s Professional Qualification Standards, can evaluate the significance of the find and determine whether additional study is warranted. Prehistoric archaeological deposits may be indicated by the presence of discolored or dark soil, fire-affected material, concentrations of fragmented or whole freshwater bivalves shell, burned or complete bone, non-local lithic materials, or the characteristic observed to be atypical of the surrounding area. Common prehistoric artifacts may include modified or battered lithic materials; lithic or bone tools that appeared to have been used for chopping, drilling, or grinding; projectile points; fired clay ceramics or non-functional items; and other items. Historic-age deposits are often indicated by the presence of glass bottles and shards, ceramic material, building or domestic refuse, ferrous metal, or old features such as concrete foundations or privies. Depending upon the significance of the find under CEQA (14 CCR 15064.5(f); PRC Section 21082), the archaeologist may simply record the find and allow work to continue. If the discovery proves significant under CEQA, additional work, such as preparation of an archaeological treatment plan, testing, or data recovery may be warranted. • In accordance with Section 7050.5 of the California Health and Safety Code, if human remains are found, the county coroner shall be immediately notified of the discovery. No further excavation or disturbance of the site or any nearby area reasonably suspected to overlie adjacent remains shall occur until the county

2 City of San Carlos Fuel Management Project Addendum A – Project Description

coroner has determined, within 2 working days of notification of the discovery, the appropriate treatment and disposition of the human remains. If the county coroner determines that the remains are, or are believed to be, Native American, he or she shall notify the NAHC in Sacramento within 24 hours. In accordance with California Public Resources Code, Section 5097.98, the NAHC must immediately notify those persons it believes to be the most likely descendant from the deceased Native American. The most likely descendant shall complete his/her inspection within 48 hours of being granted access to the site. The designated Native American representative would then determine, in consultation with the property owner, the disposition of the human remains. Biological Resources:

• To protect special-status plant species, a survey will be conducted prior to ground-disturbing activities with heavy equipment and prior to vegetation management adjacent to identified western leatherwood trees by a qualified botanist at the appropriate period when these species are evident and identifiable to identify the locations of special-status plant species within the treatment areas. If species are found within the selected treatment areas during surveys, the individuals or populations will be flagged with high-visibility flagging and completely avoided. If avoidance is not feasible, an appropriate mitigation plan will be developed and implemented. The mitigation plan will include translocation and propagation methods, monitoring requirements, and success criteria based on the identified species. • San Francisco Dusky-footed Woodrat o Woodrat nests will not intentionally be destroyed. Where feasible, an exclusion buffer of at least 10 feet from nests shall be established to avoid moving or bumping the nests or the logs or branches on which the nests rest. Screening for houses will be left in place provided the integrity of the fuel break is not compromised. o If establishing a buffer and avoiding the nests is not feasible, the nests shall be dismantled and the nesting material moved to a new location outside the project’s impact areas so that it can be used by woodrats to construct new nests. Prior to nest deconstruction, each active nest shall be disturbed by a qualified wildlife biologist to the degree that all woodrats leave the nest and seek cover out of the impact area. Whether the nest is on the ground or in a tree, the nest shall be slightly disturbed (nudged) to cause the woodrats to flee. For tree nests, a tarp shall be placed below the nest and the nest dismantled using hand tools (either from the ground or from a lift). The nest material shall then be piled at the base of a nearby tree or large shrub outside of the impact area. • White Tailed Kite, and Nesting and Migratory Birds o If possible, fuel management using goat and mastication work shall be conducted outside of the nesting bird season (February 1 through August 30, depending on species) to avoid impacts to nesting birds. o If construction will occur within the nesting season, a pre-construction nesting bird survey of all potential nest habitat within the fuel management areas, including a 100-foot buffer for passerine species and a 250-foot buffer for raptors, shall be completed by a qualified biologist no earlier than 10 days prior to beginning fuel management during the nesting season to determine if any native birds are nesting on or near the site. If there is a lapse between the survey time and initiation of work activities of 10 days or greater, the nesting bird survey should be repeated. o If active nests are encountered at any time during fuel management activities, work in that area will stop and a qualified biologist will determine a suitable avoidance buffer from the nest based on work activity and species. The nest(s) and associated avoidance buffers will be flagged by the biologist based on species, location and planned fuel management activity. These nests should be avoided until the chicks have fledged and the nests are no longer active, as determined by the biologist.

City of San Carlos Fuel Management Project Addendum B – Cultural Resources Inventory Report

April 14, 2019

Amy Newby, Director City of San Carlos Department of Parks and Recreation 600 Elm Street San Carlos, CA 94070

Subject: Cultural Resources Inventory Report for the San Carlos Fuel Management Project, City of San Carlos, California – Negative Findings

Dear Ms. Newby:

This letter documents the negative cultural resources inventory conducted by Dudek for the San Carlos Fuel Management Project (Project), located in the City of San Carlos, California. The City of San Carlos (City) is lead agency responsible for compliance with the California Environmental Quality Act (CEQA). All cultural resource fieldwork and reporting for this project has been conducted by archaeologists meeting the Secretary of the Interior’s Professional Qualifications Standards. A Native American Heritage Commission (NAHC) Sacred Lands File (SLF) search did not suggest the presence of any Native American cultural resources. A Northwest Information Center (NWIC) records search indicated that no cultural resources have been recorded within the area of potential effects (APE). Intensive-level pedestrian survey conducted of the APE did not identify cultural resources.

PROJECT LOCATION DESCRIPTION

The Project site is located in the southern portion of the City of San Carlos. The Project site is situated in Sections 14, 22, and 23, Township 18 South, Range 17 East and the very western portion of Section 9, Township 5 South, Range 4 West, on the Woodside U.S. Geological Survey 7.5- topographic quadrangles (Figure 1). The Project site is divided into four sections, each located in four parks within the city limits: Eaton Park, Big Canyon Park, Crestview Park, and Highlands Park (Figures 2 and 3). The parks are currently in use and contain athletic fields, parking lots, and hiking trails. All sections of the project area are extremely sloped with elevations ranging from 270 feet to 760 feet above mean sea level.

The Project consists of vegetation treatment or removal in an effort to reduce wildfire fuel to ensure safety of the surrounding community. The City proposes to treat vegetation in selected areas of

Subject: Cultural Resources Inventory Report for the San Carlos Fuel Management Project, City of San Carlos, California – Negative Findings

Eaton Park, Big Canyon Park, Crestview Park, and Highlands Park. The City has described three main goals for the Project:

 Conduct targeted fuel reduction treatments using hand crews, masticators, track chippers, herbicides, and herbivory to reduce highly combustible underbrush and other flammable vegetation within the defensible space zone of adjacent private ownerships.

 Create strategic fuel breaks using hand crews, masticators, track chippers, and herbivory to reduce highly combustible underbrush and other flammable vegetation along access roads and ridgelines

 Remove dead/diseased and non-native shrubs/trees as part of a comprehensive fuel reduction effort.

Maximum acreage of vegetation treatment consists 65.3 acres in Eaton Park, of 55.3 acres in Big Canyon Park, 3.4 acres in Crestview Park, and 7.4 acres in Highlands Park. The Project APE consists of all the areas of vegetation treatment, totaling 131.4 acres.

REGULATORY CONTEXT

While the Project as currently planned is subject only to state and local regulatory conditions, all work has been conducted in compliance with federal regulations as well. As such, federal regulations are also provided here for reference should they be required in the future.

Federal Regulations

National Historic Preservation Act

The NHPA established the National Register of Historic Places (NRHP) and the President’s Advisory Council on Historic Preservation (ACHP), and provided that states may establish State Historic Preservation Officers (SHPOs) to carry out some of the functions of the NHPA. Most significantly for federal agencies responsible for managing cultural resources, Section 106 of the NHPA directs that “[t]he head of any Federal agency having direct or indirect jurisdiction over a proposed Federal or federally assisted undertaking in any State and the head of any Federal department or independent agency having authority to license any undertaking shall, prior to the approval of the expenditure of any Federal funds on the undertaking or prior to the issuance of any license, as the case may be, take into account the effect of the undertaking on any district, site, building, structure, or object that is included in or eligible for inclusion in the NRHP.” Section 106 also affords the ACHP a reasonable opportunity to comment on the undertaking (16 USC 470f).

11719 2 April 2019 Subject: Cultural Resources Inventory Report for the San Carlos Fuel Management Project, City of San Carlos, California – Negative Findings

36 Code of Federal Regulations, Part 800 (36 CFR 800) implements Section 106 of the NHPA. It defines the steps necessary to identify historic properties (those cultural resources listed in or eligible for listing in the NRHP), including consultation with federally recognized Native American tribes to identify resources with important cultural values; to determine whether or not they may be adversely affected by a proposed undertaking; and the process for eliminating, reducing, or mitigating the adverse effects.

The content of 36 CFR 60.4 defines criteria for determining eligibility for listing in the NRHP. The significance of cultural resources identified during an inventory must be formally evaluated for historic significance in consultation with the California SHPO to determine if the resources are eligible for inclusion in the NRHP. Cultural resources may be considered eligible for listing if they possess integrity of location, design, setting, materials, workmanship, feeling, and association. The criteria for determining eligibility are essentially the same in content and order as those outlined under the California Environmental Quality Act (CEQA), but the criteria under NHPA are labeled A through D (rather than 1-4 under CEQA).

Regarding criteria A through D of Section 106, the quality of significance in American history, architecture, archaeology, engineering, and culture is present in districts, cultural resources, buildings, structures, and objects that possess integrity of location, design, setting, materials, workmanship, feeling, and association, and that:

A. are associated with events that have made a significant contribution to the broad patterns of our history; or B. are associated with the lives of persons significant in our past; or C. embody the distinctive characteristics of a type, period, or method of construction, or that represent the work of a master, or that possess high artistic values, or that represent a significant and distinguishable entity whose components may lack individual distinction; or D. have yielded or may be likely to yield, information important in prehistory or history [36 CFR 60.4]. The current cultural resources inventory is not designed to generate enough data to make eligibility recommendations on previously recorded cultural resources that are outside of the project area, or newly discovered cultural resources; such determinations are typically made during a subsequent evaluation phase (e.g., excavations at prehistoric sites). However, the survey was designed to generate enough information to provide informal assessments of eligibility to help guide management considerations.

State of California

The California Register of Historical Resources

In California, the term “historical resource” includes “any object, building, structure, site, area, place, record, or manuscript which is historically or archaeologically significant, or is significant in the architectural, engineering, scientific, economic, agricultural, educational, social, political, military, or cultural annals of California” (Public Resources Code (PRC) Section 5020.1(j)). In 1992, the California legislature established the California Register of Historical Resources (CRHR) “to be used by state and local agencies, private groups, and citizens to identify the state’s historical resources and to indicate what properties are to be protected, to the extent prudent and feasible, from substantial adverse change” (PRC Section 5024.1(a)). The criteria for listing resources on the CRHR, enumerated in the following text, were developed to be in accordance with previously established criteria developed for listing in the NRHP. According to PRC Section 5024.1(c)(1–4), a resource is considered historically significant if it (i) retains “substantial integrity,” and (ii) meets at least one of the following criteria:

(1) Is associated with events that have made a significant contribution to the broad patterns of California’s history and cultural heritage (2) Is associated with the lives of persons important in our past (3) Embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of an important creative individual, or possesses high artistic values (4) Has yielded, or may be likely to yield, information important in prehistory or history

To understand the historic importance of a resource, sufficient time must have passed to obtain a scholarly perspective on the events or individuals associated with the resource. A resource less than 50 years old may be considered for listing in the CRHR if it can be demonstrated that sufficient time has passed to understand its historical importance (see 14 CCR 4852(d)(2)).

The CRHR protects cultural resources by requiring evaluations of the significance of prehistoric and historic resources. The criteria for the CRHR are nearly identical to those for the NRHP, and properties listed or formally designated as eligible for listing in the NRHP are automatically listed in the CRHR, as are state landmarks and points of interest. The CRHR also includes properties designated under local ordinances or identified through local historical resource surveys.

California Environmental Quality Act

As described further in the following text, the following CEQA statutes and CEQA Guidelines are of relevance to the analysis of archaeological, historic, and tribal cultural resources:

PRC Section 21083.2(g) defines “unique archaeological resource.” PRC Section 21084.1 and CEQA Guidelines Section 15064.5(a) define “historical resources.” In addition, CEQA Guidelines Section 15064.5(b) defines the phrase “substantial adverse change in the significance of an historical resource.” It also defines the circumstances when a project would materially impair the significance of a historical resource. PRC Section 21074(a) defines “tribal cultural resources.” PRC Section 5097.98 and CEQA Guidelines Section 15064.5(e) set forth standards and steps to be employed following the accidental discovery of human remains in any location other than a dedicated ceremony.

Commission (NAHC) to resolve disputes regarding the disposition of such remains. In addition, the Native American Historic Resource Protection Act makes it a misdemeanor, punishable by up to 1 year in jail, to deface or destroy a Native American historic or cultural site that is listed or may be eligible for listing in the CRHR.

California Health and Safety Code Section 7050.5

California law protects Native American burials, skeletal remains, and associated grave goods, regardless of their antiquity, and provides for the sensitive treatment and disposition of those remains. California Health and Safety Code Section 7050.5 requires that if human remains are discovered in any place other than a dedicated cemetery, no further disturbance or excavation of the site or nearby area reasonably suspected to contain human remains can occur until the County Coroner has examined the remains (Section 7050.5b). PRC Section 5097.98 also outlines the process to be followed in the event that remains are discovered. If the County Coroner determines or has reason to believe the remains are those of a Native American, the coroner must contact the California NAHC within 24 hours (Section 7050.5c). The NAHC will notify the Most Likely Descendant. With the permission of the landowner, the Most Likely Descendant may inspect the site of discovery. The inspection must be completed within 48 hours of notification of the Most Likely Descendant by the NAHC. The Most Likely Descendant may recommend means of treating or disposing of, with appropriate dignity, the human remains and items associated with Native Americans. PRC Sections 21083.2(b)–(c) and CEQA Guidelines Section 15126.4 provide information regarding the mitigation framework for archaeological and historic resources,

11719 5 April 2019 Subject: Cultural Resources Inventory Report for the San Carlos Fuel Management Project, City of San Carlos, California – Negative Findings including examples of preservation-in-place mitigation measures; preservation-in-place is the preferred manner of mitigating impacts to significant archaeological sites because it maintains the relationship between artifacts and the archaeological context, and may also help avoid conflict with religious or cultural values of groups associated with the archaeological site(s).

Under CEQA, a project may have a significant effect on the environment if it may cause “a substantial adverse change in the significance of an historical resource” (PRC Section 21084.1; CEQA Guidelines Section 15064.5(b)). If a site is either listed or eligible for listing in the CRHR, or if it is included in a local register of historic resources, or identified as significant in a historical resources survey (meeting the requirements of PRC Section 5024.1(q)), it is a “historical resource” and is presumed to be historically or culturally significant for purposes of CEQA (PRC Section 21084.1; CEQA Guidelines Section 15064.5(a)). The lead agency is not precluded from determining that a resource is a historical resource, even if it does not fall within this presumption (PRC Section 21084.1; CEQA Guidelines Section 15064.5(a)).

A “substantial adverse change in the significance of an historical resource” reflecting a significant effect under CEQA means “physical demolition, destruction, relocation, or alteration of the resource or its immediate surroundings such that the significance of an historical resource would be materially impaired” (CEQA Guidelines Section 15064.5(b)(1); PRC Section 5020.1(q)). In turn, the significance of a historical resource is materially impaired when a project does any of the following:

(1) Demolishes or materially alters in an adverse manner those physical characteristics of an historical resource that convey its historical significance and that justify its inclusion in, or eligibility for, inclusion in the California Register; or (2) Demolishes or materially alters in an adverse manner those physical characteristics that account for its inclusion in a local register of historical resources pursuant to Section 5020.1(k) of the PRC or its identification in an historical resources survey meeting the requirements of Section 5024.1(g) of the PRC, unless the public agency reviewing the effects of the project establishes by a preponderance of evidence that the resource is not historically or culturally significant; or (3) Demolishes or materially alters in an adverse manner those physical characteristics of a historical resource that convey its historical significance and that justify its eligibility for inclusion in the California Register as

11719 6 April 2019 Subject: Cultural Resources Inventory Report for the San Carlos Fuel Management Project, City of San Carlos, California – Negative Findings

determined by a lead agency for purposes of CEQA [CEQA Guidelines Section 15064.5(b)(2)].

Pursuant to these sections, the CEQA inquiry begins with evaluating whether a project site contains any “historical resources,” then evaluates whether that project will cause a substantial adverse change in the significance of a historical resource such that the resource’s historical significance is materially impaired.

If it can be demonstrated that a project will cause damage to a unique archaeological resource, the lead agency may require reasonable efforts be made to permit any or all of these resources to be preserved in place or left in an undisturbed state. To the extent that they cannot be left undisturbed, mitigation measures are required (Section 21083.2(a), (b), and (c)).

Section 21083.2(g) defines a unique archaeological resource as an archaeological artifact, object, or site about which it can be clearly demonstrated that without merely adding to the current body of knowledge, there is a high probability that it meets any of the following criteria:

(1) Contains information needed to answer important scientific research questions and that there is a demonstrable public interest in that information (2) Has a special and particular quality such as being the oldest of its type or the best available example of its type (3) Is directly associated with a scientifically recognized important prehistoric or historic event or person

Impacts to nonunique archaeological resources are generally not considered a significant environmental impact (PRC Section 21083.2(a); CEQA Guidelines Section 15064.5(c)(4)). However, if a nonunique archaeological resource qualifies as tribal cultural resource (PRC 21074(c); 21083.2(h)), further consideration of significant impacts is required.

CEQA Guidelines Section 15064.5 assigns special importance to human remains and specifies procedures to be used when Native American remains are discovered. As described in the following text, these procedures are detailed in PRC Section 5097.98.

California State Assembly Bill 52

Assembly Bill (AB) 52 of 2014 amended PRC Section 5097.94 and added PRC Sections 21073, 21074, 21080.3.1, 21080.3.2, 21082.3, 21083.09, 21084.2, and 21084.3. AB 52 established that Tribal Cultural Resources (TCR) must be considered under CEQA and also provided for additional Native American consultation requirements for the lead agency. Section 21074 describes a TCR

11719 7 April 2019 Subject: Cultural Resources Inventory Report for the San Carlos Fuel Management Project, City of San Carlos, California – Negative Findings as a site, feature, place, cultural landscape, sacred place, or object that is considered of cultural value to a California Native American Tribe. A TCR is either:

 On the California Register of Historical Resources or a local historic register; Eligible for the California Register of Historical Resources or a local historic register; or  A resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision (c) of Section 5024.1. AB 52 formalizes the lead agency–tribal consultation process, requiring the lead agency to initiate consultation with California Native American groups that are traditionally and culturally affiliated with the project, including tribes that may not be federally recognized. Lead agencies are required to begin consultation prior to the release of a negative declaration, mitigated negative declaration, or environmental impact report.

Section 1 (a)(9) of AB 52 establishes that “a substantial adverse change to a tribal cultural resource has a significant effect on the environment.” Effects on tribal cultural resources should be considered under CEQA. Section 6 of AB 52 adds Section 21080.3.2 to the PRC, which states that parties may propose mitigation measures “capable of avoiding or substantially lessening potential significant impacts to a tribal cultural resource or alternatives that would avoid significant impacts to a tribal cultural resource.” Further, if a California Native American tribe requests consultation regarding project alternatives, mitigation measures, or significant effects to tribal cultural resources, the consultation shall include those topics (PRC Section 21080.3.2[a]). The environmental document and the mitigation monitoring and reporting program (where applicable) shall include any mitigation measures that are adopted (PRC Section 21082.3[a]).

Native American Human Remains

State law (PRC Section 5097 et seq.) addresses the disposition of Native American burials in archaeological sites and protects such remains from disturbance, vandalism, or inadvertent destruction; establishes procedures to be implemented if Native American skeletal remains are discovered during construction of a project; and established the Native American Heritage Commission (NAHC).

In the event that Native American human remains or related cultural material are encountered, Section 15064.5(e) of the CEQA Guidelines (as incorporated from PRC Section 5097.98) and California Health and Safety Code Section 7050.5 define the subsequent protocol. In the event of the accidental discovery or recognition of any human remains, excavation or other disturbances shall be suspended of the site or any nearby area reasonably suspected to overlie adjacent human remains or related material. Protocol requires that a county-approved coroner be contacted in order

11719 8 April 2019 Subject: Cultural Resources Inventory Report for the San Carlos Fuel Management Project, City of San Carlos, California – Negative Findings to determine if the remains are of Native American origin. Should the coroner determine the remains to be Native American, the coroner must contact the NAHC within 24 hours. The most likely descendent may make recommendations to the landowner or the person responsible for the excavation work, for means of treating, with appropriate dignity, the human remains and any associated grave goods as provided in PRC Section 5097.98 (14 CCR 15064.5(e)).

NWIC RECORDS SEARCH

A records search of the APE and the surrounding one half-mile was completed by Dudek staff on March 1, 2019 (Confidential Appendix A). This search included their collection of mapped prehistoric, historical and built-environment resources, Department of Parks and Recreation (DPR) Site Records, technical reports, archival resources, and ethnographic references. Additional consulted sources included the National Register of Historic Places (NRHP), California Inventory of Historical Resources/CRHR and listed OHP Archaeological Determinations of Eligibility, California Points of Historical Interest, California Historical Landmarks, and Caltrans Bridge Survey information.

Previously Conducted Studies:

NWIC records indicate that fifteen (15) previous cultural resources technical investigations have been conducted within a one half-mile of APE. Of these, none have included any portion of the current APE (Table 1).

NAHC CORRESPONDENCE

Dudek requested a NAHC search of their Sacred Lands File on March 8, 2019 for the proposed project area. The NAHC provided results on March 13, 2019. This search did not indicate the presence of Native American sacred sites or cultural resources within this area or the surrounding one half-mile buffer (Appendix B). The NAHC additionally provided a list of Native American tribes and individuals/organizations that might have knowledge of cultural resources in this area.

The proposed project is subject to compliance with Assembly Bill 52 (PRC Section 21074), which requires consideration of impacts to “tribal cultural resources” as part of the CEQA process, and requires the CEQA lead agency to notify any groups (who have requested notification) of the proposed project who are traditionally or culturally affiliated with the geographic area of the project. Because Assembly Bill 52 is a government-to-government process, all records of correspondence related to Assembly Bill 52 notification and any subsequent consultation are on file with the City.

METHODS

Intensive Pedestrian Survey

Dudek Archaeologist William Burns inspected all areas of the APE on March 12, 2019. No archaeological or historic-era built-environment artifacts or features were identified. Modern developments (concrete lined drainage ditches, hiking paths, park equipment and landscaping)

11719 11 April 2019 Subject: Cultural Resources Inventory Report for the San Carlos Fuel Management Project, City of San Carlos, California – Negative Findings were observed within the project area. All areas of the APE appeared to have either been previously disturbed through grading or landscaping of park areas or have extreme slopes indicating a low potential for archaeological resources. Assessment of each survey area is as follows.

Eaton Park is the largest survey area at 65.3 acres. The park appears relatively undisturbed with the exception of hiking trails. The park contains hills and canyons filled with oak, pine, bay trees, sagebrush, and poison oak. The vast majority of the park consists of slopes between 20° (37%) and 50° (120%). Much of the area was covered in grass reducing ground visibility to 20% overall. Artifacts and archaeological deposits were opportunistically sought after in exposed trails, areas of natural erosion, and animal burrows, particularly in more level areas. No cultural resources were observed.

Big Canyon Park is the largest survey area after Eaton Park at 55.3 acres. This park also consists entirely of hiking trails, some of which have been closed due to erosion. The park appears as relatively undisturbed as Eaton Park. The park contains hills and canyons filled with oak, pine, bay trees, sagebrush, and poison oak. The vast majority of the park consists of slopes between 20° and 50°. Much of the area was covered in grass reducing ground visibility to 20% overall. Artifacts and archaeological deposits were opportunistically sought out in exposed trails, areas of natural erosion, and animal burrows, especially in more level areas. No cultural resources were observed.

Crestview Park is a small park west of Big Canyon Park and is the smallest survey area at 3.4 acres. This survey area consists of landscaped areas surrounding a soccer field, a basketball court, and a parking lot. The park displays high levels of disturbance due to the park facilities and grading and landscaping surrounding it. The survey area is relatively flat adjacent to the athletic fields and then slopes down as one moves away from the fields in a 40° (84%) slope. Much of the area was covered in grass reducing ground visibility to 20% overall. Artifacts and archaeological deposits were opportunistically sought out in exposed trails, areas of natural erosion, and animal burrows, especially in more level areas. No cultural resources were observed.

Highlands Park is a small park north of Big Canyon Park with a survey area of 7.4 acres. This survey area consists of landscaped areas surrounding several mixed-use athletic fields. The park displays high levels of disturbance due to the park facilities and grading and landscaping surrounding it. The survey area is relatively flat adjacent to the athletic fields and then slopes down as one moves away from the fields in a 40° slope. The sloped area contains several modern concrete lined irrigation ditches. Much of the area was covered in grass reducing ground visibility to 20% overall. Artifacts and archaeological deposits were opportunistically sought out in exposed trails, areas of natural erosion, and animal burrows, especially in more level areas. No cultural resources were observed.

GEOMORPHOLOGY

Archaeological Sensitivity

Potential for yet identified cultural resources in the vicinity was reviewed against geologic and topographic GIS data for the area and information from other near-by projects. The “archaeological sensitivity,” or potential to support the presence of buried prehistoric archaeological deposits, is generally interpreted based on geologic landform and environmental parameters (i.e., distance to water and landform slope). The landform in the area is comprised of Franciscan Complex generally associated with the Mesozoic. Several small drainages are present in the vicinity of the project area but no major drainages. The vast majority of the project area consists of extreme slopes ranging from 20° to 50°, which are topographically unsuited to provide for the formation of archaeological deposits. Based on review of this information, the project area is indicated to have a low-moderate potential for unanticipated buried cultural resources.

The likelihood for significant prehistoric archaeological sites to be present within the project area is considered low-moderate. Given the extreme slopes and the lack of permanent water, the most likely type of prehistoric site in this area would be related to non-intensive use and non-reoccurring activities. The potential for small historic-period sites such as trash scatters and water-related features within the project site is considered low due to extreme slopes.

SUMMARY AND MANAGEMENT CONSIDERATIONS

No archaeological resources were identified within the Project site or immediate vicinity as a result of intensive pedestrian survey, the CHRIS records search or NAHC SLF search. However, it is always possible that intact archaeological deposits are present at subsurface levels. Based on geomorphological evidence, the area has a relatively low potential to contain unanticipated cultural resources. Management recommendations to reduce potential impacts to unanticipated archaeological resources and human remains during work activities are provided below.

Unanticipated Archaeological Resources

All crews should be alerted to the potential to encounter archaeological material. In the event that cultural resources (sites, features, or artifacts) are exposed during work activities for the proposed project, all ground disturbing work occurring within 100 feet of the find shall immediately stop until a qualified specialist, meeting the Secretary of the Interior’s Professional Qualification Standards, can evaluate the significance of the find and determine whether additional study is warranted. Prehistoric archaeological deposits may be indicated by the presence of discolored or dark soil, fire-affected material, concentrations of fragmented or whole freshwater bivalves shell, burned or complete bone, non-local lithic materials, or the characteristic observed to be atypical

11719 13 April 2019 Subject: Cultural Resources Inventory Report for the San Carlos Fuel Management Project, City of San Carlos, California – Negative Findings of the surrounding area. Common prehistoric artifacts may include modified or battered lithic materials; lithic or bone tools that appeared to have been used for chopping, drilling, or grinding; projectile points; fired clay ceramics or non-functional items; and other items. Historic-age deposits are often indicated by the presence of glass bottles and shards, ceramic material, building or domestic refuse, ferrous metal, or old features such as concrete foundations or privies. Depending upon the significance of the find under CEQA (14 CCR 15064.5(f); PRC Section 21082), the archaeologist may simply record the find and allow work to continue. If the discovery proves significant under CEQA, additional work, such as preparation of an archaeological treatment plan, testing, or data recovery may be warranted.

Unanticipated Human Remains

In accordance with Section 7050.5 of the California Health and Safety Code, if human remains are found, the county coroner shall be immediately notified of the discovery. No further excavation or disturbance of the site or any nearby area reasonably suspected to overlie adjacent remains shall occur until the county coroner has determined, within 2 working days of notification of the discovery, the appropriate treatment and disposition of the human remains. If the county coroner determines that the remains are, or are believed to be, Native American, he or she shall notify the NAHC in Sacramento within 24 hours. In accordance with California Public Resources Code, Section 5097.98, the NAHC must immediately notify those persons it believes to be the most likely descendant from the deceased Native American. The most likely descendant shall complete his/her inspection within 48 hours of being granted access to the site. The designated Native American representative would then determine, in consultation with the property owner, the disposition of the human remains.

Should you have any questions relating to this report and its findings please do not hesitate to contact me directly.

RE: San Carlos Fuel Management Project, City of San Carlos; Woodside USGS Quadrangle, San Mateo County, California.

Dear Mr. Burns:

A record search of the Native American Heritage Commission (NAHC) Sacred Lands File (SLF) was completed for the information you have submitted for the above referenced project. The results were negative. However, the absence of specific site information in the SLF does not indicate the absence of cultural resources in any project area. Other sources of cultural resources should also be contacted for information regarding known and recorded sites.

Attached is a list of Native American tribes who may also have knowledge of cultural resources in the project area. This list should provide a starting place in locating areas of potential adverse impact within the proposed project area. I suggest you contact all of those indicated; if they cannot supply information, they might recommend others with specific knowledge. By contacting all those listed, your organization will be better able to respond to claims of failure to consult with the appropriate tribe. If a response has not been received within two weeks of notification, the Commission requests that you follow-up with a telephone call or email to ensure that the project information has been received.

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 lists contain current information. If you have any questions or need additional information, please contact me at my email address: [email protected].

Sincerely,

Gayle Totton, Totton B.S., M.A., Ph.D. Associate Governmental Program Analyst
