Document Description
As a result of the San Simeon Earthquake of December 2003, a geothermal sulfur spring surfaced in the parking lot serving the City Hall and Library. The spring continues to flow to the Salinas River and a portion of the parking lot remains damaged and unusable. The project proposes to reclaim the parking lot through the following three construction efforts: 1) collection of the geothermal water in a filtration/vault system and repair of the parking lot; 2) construct a conveyance pipeline to the Municipal Water Yard within City streets and under Highway 101 and the Union Pacific Rail Road right of way; and 3) construct a percolation leachfield at the Municipal Water Yard to discharge the spring water to the underflow of the Salinas River (a ground discharge).
