Due to the lack of restroom facilities at Santa Susana Pass State Historic Park, visitors often use the surrounding vegetation, creating public health and wildlife concerns. The Foundation for the Preservation of the Santa Susana Mountains is installing permanent vaulted toilets at two trailheads to better serve park visitors and protect the park’s habitat.
"The Santa Susana Pass State Historic Park is classified as an “undeveloped” Park. One of the disadvantages is the lack of toilet facilities. For Park events, Our Foundation rents portable sanitation units to fill this void. The Angeles Sector of the CA DPR has committed making the Park trails more hospitable to visitors by installing permanent SST vault toilets at two major trailheads to the Park. The entire cost of transporting the toilets from their storage site and installing them is beyond the DPR’s budget. The California State Parks Foundation’s Park Enrichment Grant makes this project possible."
