NOE - Notice of Exemption
Document Description
The Porterville Developmental Center water system has two existing storage tanks; one 1-MIL Gallon water reservoir constructed with concrete material. rectangular shaped, semi-buried, and enclosed structure constructed in 1950, and a steel cylindrical 500,000 Gallon tank. The project consists of replacing the exterior water lines valves next to the concrete reservoir. Work includes the removal and in-kind replacement of the above grade 10” gate valves on the two inflow/outflow pipelines of the concrete water reservoir, and the installation of a new below grade isolation gate valve on the 12” water line running down to the campus, near the concrete reservoir. The new valve will allow the 1-MIL Gallon tank to be taken off-line while maintaining water service to campus facilities through the second water tank. The concrete storage reservoir, constructed in 1951, is a contributor to the National Register-eligible Porteville State Hospital Historic District. Therefore, the project is designed to meet the Secretary of the Interior’s Standards for Rehabilitation.
