Trask House Garage Reroof

The Trask House Garage Reroof project, managed by the California Department of Parks and Recreation, involves the replacement of a worn and leaking roof on the Trask House garage located within Columbia State Historic Park in Tuolumne County. The primary objective is to ensure the facility remains viable for storing district office records and supplies. The scope of work includes removing existing cedar shingles and repairing soffits, flashing, rafters, joists, and rafter tails using in-kind materials. Technical specifications require the installation of half-inch OSB plywood over existing skip sheeting, painted cedar at exposed ends, rubber underlayment, nylon cedar breather, and white metal drip edges at the eaves. The roof will be finished with 16-inch Class B fire-rated cedar shingles. Additionally, the project includes interior repairs to remove and replace damaged drywall, which will be taped, sanded, and painted to match the existing ceiling. Because the project is located within a historic park, all work must adhere to the Secretary of the Interior's Standards for the Treatment of Historic Properties and the 1995 Guidelines for Preserving, Rehabilitating, Restoring, and Reconstructing Historic Buildings. The project is classified under categorical exemption classes 1, 2, and 31, as it consists of minor alterations and maintenance without expanding the current use of the structure. Administrative oversight is provided by Andrew Collum, an Environmental Scientist with the DEC Central Valley District. The project is categorized under NAICS code 238160.
