Sunnyvale East and West Channels

Brief description:
As part of the water district’s 15-year Clean, Safe Creeks and Natural Flood Protection Plan approved by the voters in November 2000,  the  Sunnyvale East and West Channels Flood Protection Project  (fact sheet, PDF), located in the cities of Cupertino and Sunnyvale, will identify and implement improvements in flood protection, erosion control, water quality, sediment reduction, and environmental and recreational enhancements.

The project's primary objectives are to protect 1,618 homes and 47 acres of highly valuable industrial and government lands from the 100-year riverine flood, saving potential flood damages in excess of $33.6 million.

Project scope of work/goals:
The Sunnyvale East and West Channels were identified initially as separate projects in the Clean, Safe Creeks Plan. In order to combine efforts and improve efficiency, the Planning Phase of the two projects was performed as a single planning effort. After the conclusion of the Planning Phase, the design phase was initiated for the Sunnyvale East and West Channels and is being performed as a single design effort.

  • Provide 100-year riverine flood protection to 1,618 parcels in the Sunnyvale East Channel Watershed and to 47 acres of industrial and government lands in the Sunnyvale West Channel Watershed.
  • Provide erosion control measures to decrease sediment and turbidity thereby improving water quality.
  • Provide for recreation enhancements by accommodating the City of Sunnyvale's trail plan
  • Revise the FEMA flood hazard maps to reflect 100-year flood protection along the improved channels to eliminate the requirements for flood insurance in this community.
