Document Description
Santa Clara Valley Water District (Valley Water) is proposing to replace the existing Palo Alto Flood Basin tide gate structure in order to maintain flood protection in the communities surrounding the flood basin and along the U.S. Highway 101 corridor. The Project would involve construction of a new 132-foot-wide tide gate structure slightly inboard (upstream) and southeast of the existing 113-foot-wide deteriorating tide gate structure, removal of the existing tide gate structure and levee, and construction of a new levee that ties into the new tide gate structure. Construction of the Project would occur in two phases with separate dewatering systems to allow continued operation of a tide gate throughout construction. Specific project elements include up to 2.3 miles of levee trail resurfacing (for access); installation of two sheet pile dewatering systems; construction of the new tide gate structure on a concrete foundation supported by drilled piles; demolition and removal of the existing tide gate structure and levee; and construction of a new levee connecting to the new tide gate structure. Construction would span up to 5 years but would be limited to September 1 through January 31 annually to avoid and minimize impacts on biological resources.
