The objective of the Hale Creek Enhancement Pilot Project (Project) is to provide Santa Clara Valley Water District (Valley Water) the opportunity to examine a new approach using a hybrid method, instead of only hardscape, to test the potential for restoration of geomorphic habitat functions to a concrete-lined channel in an urbanized and constrained setting while maintaining and enhancing flood protection. The Project is part of the voter-approved renewed Safe, Clean Water and Natural Flood Protection Program (Safe, Clean Water Program) under Project D6: Restoration of Natural Creek Functions.

life.
