1.0 INTRODUCTION
A special-status plant survey for the approximately 1.63-acre Badger Street Bridge site (Project) in Amador County, California was conducted to identify and map the locations of special-status plant species observed within the site.
For the purposes of this report, “special-status species” refers to those plant species which:
Are listed, proposed for listing, or candidates for future listing as threatened or endangered under the federal Endangered Species Act (FESA); Are listed or candidates for future listing as threatened or endangered under the California Endangered Species Act (CESA); Meet the definitions of endangered or rare under Section 15380 of the CEQA Guidelines; Are considered by the California Native Plant Society (CNPS) to be "rare, threatened, or endangered in California" [California Rare Plant Rank (CRPR) 1B and 2 (formerly CNPS List 1B and 2)]; or Are listed as rare under the California Native Plant Protection Act (Fish and Game Code of California, Section 1900 et seq.).
CRPR 3 and 4 species (Review List and Watch List, respectively) for Amador County were not considered to be target species for this survey. If any of these species were encountered during the course of the survey, the locations were mapped and included within the discussion section of this report.
1.1 Site Location
The proposed project is located in the City of Sutter Creek along Badger Street, approximately 0.1 mile west of Old Highway 49 in Amador County, California (Figure 1. Project Location and Vicinity). The site corresponds to portions of Sections 6 and 7, Township 6 North, and Range 11 East [(Mount Diablo Base and Meridian (MDBM)] of the “Amador City, California” 7.5-minute United States Geological Survey (USGS) topographic quadrangle [U.S. Department of the

1.2 Existing Site Conditions
The Project site is situated at an elevation of approximately 1,150 to 1,200 feet above mean sea level. The bridge is located approximately 1,170 feet above mean sea level in the center of the Project site. Sutter Creek and its floodplain are at the lowest elevation on site (approximately 1,150 feet) and elevations rise to approximately 1,200 feet on the west side of the Project site, sloping upwards towards Cemetery Road.
1.2.1 Vegetation Communities
The Project site contains six vegetation communities or habitat types, including oak woodland, intermittent drainage, perennial creek (Sutter Creek), riparian scrub, ruderal/disturbed, and developed (existing roads and other paved surfaces and residences) (Figure 2. Vegetation Map).
Two oak woodland areas occur including one area west of the existing bridge/roadway and a second area that is along the edge of Badger Street southeast of the existing bridge. The dominant trees include blue oak (Quercus douglasii), Valley oak (Quercus lobata), and Interior live oak (Quercus wislizenii). The understory is mostly herbaceous grasses and forbs including wild oat (Avena fatua), rip-gut brome (Bromus diandrus), and rose clover (Trifolium hirtum).
An intermittent drainage occurs along the western fringe of Badger Street north of the existing bridge. Vegetation within the intermittent drainage includes a variety of plant species commonly found in wetlands, including narrow-leaf cattail (Typha angustifolia), tall flatsedge (Cyperus eragrostis), horsetail (Equisetum arvense), Himalayan blackberry (Rubus armeniacus), common velvet grass (Holcus lanatus), and rice cutgrass (Leersia oryzoides).

The dominant trees within the riparian scrub community are arroyo willow (Salix lasiolepis) and sandbar willow (Salix exigua). Other trees include white alder (Alnus rhombifolia) and Fremont’s cottonwood (Populus fremontii). Herbaceous species found within the riparian scrub community include cattail, soft rush (Juncus effusus), rice cutgrass, tall flatsedge, common velvet grass, and horsetail.
A portion of the perennial Sutter Creek occurs within the Project site. The creek consists primarily of open water but also supports fringe areas of emergent wetland vegetation such as cattail and sedge. The fringe areas also support a variety of wetland plant species including arroyo willow, white alder, Fremont’s cottonwood, soft rush, rice cutgrass, tall flatsedge, common velvet grass, and horsetail.
The remaining area within the Project site is paved and/or developed. This includes the existing bridge, paved/gravel roadways, residences and outbuildings. These areas are devoid of vegetation.
1.2.2 Wetlands and Other Waters of the U.S.
A wetland delineation was conducted on 9 and 10 October 2012 by ECORP (ECORP 2013) (Figure 3. Wetland Delineation Map Jurisdictional features include an intermittent drainage, a perennial creek (a portion of Sutter Creek) and the riparian scrub wetland within the floodplain of the creek. These features were described as part of the vegetation communities in Section 1.2.1. and include a total of 0.51 ac [0.20 ha] of Waters of the U.S. Included in this acreage total are 0.05 ac [0.02 ha] of intermittent drainage, 0.10 ac [0.04 ha] of Sutter Creek (a perennial creek), and 0.36 ac [0.15 ha] of riparian scrub.
1.2.3 Soils
According to the Soil Survey of Amador County, California (U.S. Department of Agriculture, SSURGO data 2013), four (4) soil units, or types, have been mapped within the Project site: (AsD) Auburn very rocky silt loam, 3 to 31 percent slopes; (AsE) Auburn very rocky silt loam, 31 to 51 percent slopes ; (EcE) Exchequer very rocky silt loam, 31 to 51 percent slopes, and (Mn) Mine tailings and Riverwash (Figure 4.

Natural Resources Conservation Service Soil Types 2012-106 Sutter Creek-Badger Street Bridge Replacement 2.0 METHODS
The special-status plant survey included a review of resource agency species lists, literature review, on- line database query, voucher specimen and reference population review, and field surveys. Background information was collected on the potential existence of the special-status plants within or near the site from a variety of sources including:
California Department of Fish and Game's Natural Diversity Database (CNDDB) record search for the “Amador City, California” 7.5-minute quadrangle and the eight surrounding quadrangles (CDFG 2003); California Native Plant Society’s Inventory of Rare and Endangered Plants record search for the “Amador City, California” 7.5-minute quadrangle and the eight surrounding quadrangles (CNPS 2013); Species List for the “Amador City, California” 7.5-minute quadrangle created by the U.S. Fish and Wildlife Service (USFWS) (USFWS 2013); Status of Rare, Threatened, and Endangered Animal and Plants of California 2000-2004 (CDFG 2005); Inventory of Rare and Endangered Vascular Plants of California (CNPS 2001); Soil Survey of Amador County, California (U.S. Department of Agriculture, SSURGO data 2013); and Wetland Delineation for Badger Street Bridge Replacement, Amador County (ECORP 2013).
Focused rare plant surveys were conducted in accordance with guidelines promulgated by the U.S. Fish and Wildlife Service (USFWS 2000), California Department of Fish and Game (CDFG 1983), and California Native Plant Society (CNPS 2001). The field surveys were conducted on 2 July 2013. ECORP botanist Daria Snider walked meandering transects throughout the site to ensure complete coverage of all suitable habitat, including all aquatic features on-site. Ms. Snider’s qualifications are included as Attachment A.
Reference populations for the target species were visited to assess bloom phenology and to observe species morphology. When reference populations were not available, mounted herbarium specimens were observed at the U.C. Davis Herbarium. Attachment B identifies the reference source for each of the
8 2012-106 Rare Plant Report target species including the location of the population, dates of visits, and phenological stage of the species at the time of the field visits.
Plant species identification, nomenclature, and taxonomy followed The Jepson Manual, Second Edition (Baldwin et al 2012). Vegetation community classification was based on the classification systems presented in A Manual of California Vegetation, Second Edition (Sawyer, Keeler-Wolf, and Evans 2009), Preliminary Descriptions of the Terrestrial Natural Communities of California (Holland 1986), and A Guide to Wildlife Habitats of California (Mayer and Laudenslayer Jr. 1988).
3.0 RESULTS AND DISCUSSION
3.1 Previously Documented Special-Status Plant Occurrences
There are no previously documented occurrences of special-status plants within the site in the CNDDB (CDFG 2003). However, prairie wedge grass (Sphenopholis obtusata, CRPR 2) occurs within the vicinity (approximately five-mile radius) of the Project site (Figure 5. CNDDB Occurrence Records for Special- Status Plant Species).
This species was evaluated for its potential to occur on-site. Additional species located outside of the five-mile radius around the site were also evaluated for their potential to occur on-site due to the presence of suitable habitat.
3.2 Target Species
Based on the information listed above, vegetation communities and conditions present within the site, and data on known species’ distribution, a list of potentially occurring special-status plants was developed (Table 1). The target special-status plant species for this survey are:
Hoover's calycadenia (Calycadenia hooveri, CRPR 1B) Tuolumne button celery (Eryngium pinnatisectum, CRPR 1B ),
