Summary The City of Angels Camp intends to install continuous sidewalks, upgrade designated crosswalks, and install Class II bicycle lanes along State Route (SR) 49/ South Main Street between Murphy’s Grade Road and Utica Park, using Transportation Enhancement (TE) funds. Compliance is required with the National Environmental Policy Act (NEPA), Executive Orders, and other federal laws, such as the Federal Endangered Species Act (FESA). The Caltrans Local Assistance Program Manual (Caltrans 2004) describes the environmental procedures needed for local agencies to apply for federal funds and for compliance with Executive Orders and other federal laws including FESA and NEPA. Caltrans administers the TE program for Federal Highway Administration (FHWA) and is responsible for ensuring that appropriate technical studies have been prepared to support NEPA findings and compliance with Executive Orders and other federal laws. As the lead local agency, City of Angels Camp is responsible for compliance with the California Environmental Quality Act (CEQA). The Project is along a high-traffic road and will impact existing paved road shoulders, disturbed shoulders that have been colonized by ruderal plant species, and landscaped areas. The Biological Study Area (BSA) does not provide suitable habitat for federal or state listed plant or wildlife species. The Angels Camp Sidewalk Enhancement Project (Project) will have no effect on federal- and state-listed special-status species. No sensitive natural communities occur in the BSA. No wetlands or waters occur in the BSA and no wetlands or waters will be affected by the Project. The project will require a Caltrans encroachment permit. 2. Introduction 2.1. Project History The Project is a Transportation Enhancement (TE) project that is federally and locally funded. The purpose of the project is to construct sidewalks and landscaping on South Main Street/ SR-49 south of Murphy's Grade Road. The new sidewalks will create a safe, continuous pedestrian corridor along South Main Street. 10-0T350_AngelsCampSidewalks_NESMI.doc 6/22/2010 1 2.2. Project Location The approximately 0.76-ac biological study area (BSA) is located on SR-49/ South Main Street approximately 800 feet east of the intersection of SR-49 and Murphy Grade Road in the City of Angels Camp, CA (Figure 1). The BSA is on the Angels Camp, CA USGS 7.5’ topographic quad (T3N, R13E, Section 28 and 33). The BSA is in the Upper Stanislaus Watershed (hydrologic unit code 18040010), and its centroid is 38.076983°N latitude, 120.549447°W longitude (1983 NAD) (UTM Coordinates: 714,943 meters East, 4,217,192 meters North, UTM Zone 10 NAD83). 2.3. Project Description The City of Angels Camp intends to install continuous sidewalks, upgrade designated crosswalks, and install Class II bicycle lanes along State Route 49/ South Main Street south of Murphy’s Grade Road, using Transportation Enhancement (TE) funds. Work will be in Caltrans Right of Way with temporary construction easements for driveway conforms and slope. Landscaping will be included in the project where there is sufficient room for landscaping. Sidewalks are already present on most of South Main Street. Three sections along SR-49/ South Main Street will be constructed: Section 21 immediately east of Lee Lane, Section 24 between Stanislaus Ave and Mark Twain Road, and Section 25 immediately east of Mark Twain Road. Section 21 will add about 400 feet of sidewalk; Section 24 will add about 312 feet of sidewalk; and Section 25 will add 295 feet of sidewalk. 3. Study Methods File data on special-status species that potentially occur in the vicinity of the Project was made from USFWS (2010) . Their response is in Appendix A. A search of the DFG California Natural Diversity Database (CNDDB/ RareFind report dated 1 May 2010; DFG 2010a; Appendix B) was conducted for the Angels Camp USGS topographic quad and eight adjacent quads to determine if there were any known occurrences of state- or federal-listed species in or near the BSA. Data received from USFWS, CNDDB/ RareFind records, and DFG (2010a) species lists were used to compile a table of regional species and habitats of concern (Appendix C). Site visits were conducted by Jeff Little and Jessica Easley, a biologist and certified arborist, on 30 April 2010, and 25 May and 14 June 2010 by Jeff Little. The BSA was surveyed by vehicle to determine if any special-status plant or wildlife species or their habitat were present. 10-0T350_AngelsCampSidewalks_NESMI.doc 6/22/2010 2 4. Environmental Setting 4.1. Physical Conditions The BSA is located in the foothills of the Sierra Nevada in the City of Angels Camp along SR-49 (South Main Street). Elevation of the BSA is approximately 1,540 ft above sea level. Topography of the BSA consists of flat ground and gentle slopes of varying aspect. Land surrounding the BSA is mostly developed with residential and commercial uses. Pavement covers most of the BSA and the areas that will be impacted by the project are mostly paved. 4.2. Biological Conditions in the BSA The BSA is occupied by paved roadways and disturbed and landscaped road shoulders. Ruderal species such as wild oat (Avena sp.) and common dandelion (Taraxacum officinale) occur along the road shoulders and in weak ditches. Landscaping occurs along much of the area where sidewalks are to be installed. No wetlands or waters of the U.S. occur in the BSA. One elderberry (Sambucus mexicana) shrub occurs on SR 49/S. Main Street opposite the Stanislaus Ave intersection. The shrub is outside of the Biological Study Area. No project activities occur within 100 ft of the shrub. This shrub does not occur in a riparian corridor and is located close to SR 49. The project will have no effect on this shrub. 4.3. Regional Species and Habitats of Concern Field surveys were conducted to determine if individuals or suitable habitat for special-status species occur in the BSA. Special-status species listed in the USFWS letter (Appendix A) and the CNDDB (Appendix B) are listed in Table 2. Species for which there is no habitat in the BSA, or whose range precludes their occurrence in the BSA, are not discussed further. Table 1.
