Calabazas Creek Capacity Improvement Project

Brief description:
The Calabazas Creek Capacity Improvement Project which extends from San Francisco Bay to Miller Avenue in Cupertino was completed in 2007.

The purpose of the Calabazas Creek Capacity Improvement Project was to identify improvements to channel sections on Calabazas Creek, to achieve one-percent flood protection between San Francisco Bay and Miller Avenue, to obtain a Letter of Map Revision (LOMR) from the Federal Emergency Management Agency (FEMA), and to stabilize the channel between Lawrence Expressway and Miller Avenue. In January 2010, letters and final LOMR maps were mailed to residents along this stretch of Calabazas Creek to inform them that FEMA approved changes to the LOMR for the Calabazas Creek Flood Protection Project. A one-percent flood is an event which has a one percent chance of occuring in any given year (also known as a 100-year flood).

These channel improvements removed 2,250 parcels from the existing one-percent floodplain, extending over portions of the cities of Santa Clara, San Jose, and Cupertino and stabilize the channel invert.

Project goals:

  • Provide continuous one-percent flood protection between San Francisco Bay and Miller Avenue to remove 2,250 parcels from the one-percent floodplain.
  • Stabilize channel invert along Calabazas Creek between Lawrence Expressway and Miller Avenue.
