This project would establish or restore underground water and sewer and overhead electrical services to 58 existing spaces in the El Portal trailer court owned by the National Park Service. Established in 1958, The El Portal trailer court was located within the NPS Administrative Area between US Highway 140 and the Merced River in El Portal, California. Approximately 25 spaces are currently occupied; several spaces are temporarily used by seasonal NPS staff or contractors. The proposed temporary use of the trailer court by seasonal concessioner employees is compatible with the established and ongoing land-use in the El Portal trailer court. This project would accommodate privately-owned mobile housing (e.g., roll-in/roll-out trailers, fifth-wheels, or recreational vehicles) that would directly connect to the onsite water, sewer, and electrical services provided to each space
