Folsom Powerhouse Parking Lot Improvements

Folsom Powerhouse Parking Lot Improvements

Construct a formal paved parking lot at the existing informal parking area adjacent to Riley Street in Folsom Powerhouse State Historic Park. Pave and stripe 28 parking spaces, including three ADA-compliant accessible spaces; install walkways and curbs around the parking area and construct a small trailhead plaza area using locally native plant species and install an irrigation system. Preserve three mature oak trees within the parking lot project area and one elderberry shrub that is 25 feet outside the project boundary. Specific conditions developed in consultation with the US Fish and Wildlife Service shall be implemented as part of the project to protect the shrub which is the host for the Valley Elderberry Longhorn Beetle (VELB), a federally designated threatened species. These dustproof barrier around the shurb if work occurs from March through June, the active feeding and mating season for VELB; prohibiting construction activities within 15 feet of the shrub; and watering exposed soil in the construction area within 100 feet of the shrub as needed to minimize dust impacts. The existing parking area is part of an old paved roadway and the new paved lot will require minimal grading; however, a DPR-qualified archaeologist will monitor excavation of the wall footing and electric light on the south side of the project area. If potentially-significant cultural resources are unearthed, work in the immediate area of the find will be temporarily halted or diverted until identification and proper treatment are completed. The project manager shall notify the archaeologist a minimum of two weeks before the project excavation activities will take place.
