Castle Crags Accessibility Improvements - Geotech Investigation

The California Department of Parks and Recreation, through its Northern Service Center, is seeking geotechnical investigation services at Castle Crags State Park in Dunsmuir, California. The primary objective is to identify soil conditions at potential building locations to guide the construction or replacement of facilities within the park's Day Use and Campground areas to improve accessibility. This project is categorized as a forecast under NAICS code 541380 and is considered categorically exempt from certain environmental reviews as it involves basic data collection and resource evaluation. The scope of work requires the use of a truck-mounted drill equipped with hollow-stem or solid flight augers. In the proposed new restroom area, the contractor must drill two 6-inch diameter borings at a depth of 15 feet and perform three percolation tests in shallow boreholes for a new leach field. For the existing leach field area, the requirements include drilling one 15-foot deep boring, machine excavating 6 to 8 exploratory test pits, and hand excavating 15 test pits. All borings must be logged according to the Unified Soil Classification System and backfilled with excavated materials. Monica Aleman serves as the primary point of contact for this effort.
