As part of the district’s 15-year Clean, Safe Creeks Program, the Permanente Creek Flood Protection Project , located in the cities of Cupertino, Los Altos and Mountain View, has been selected for improvements in flood protection, erosion control, structural repair, sediment reduction, and habitat restoration. The planning and design phases of this project are included as part of the district’s Capital Improvement Plan.
The project goal is to provide flood protection to homes, streets, businesses, and public facilities in the Permanente Creek watershed using Natural Flood Protection approach.
- Develop a plan for the entire watershed that presents alternatives and a recommendation for providing flood protection for all flows up to the one-percent flood for Permanente Creek, Hale Creek, and the Permanente Diversion between Foothill Expressway and San Francisco Bay.
- Identify opportunities for environmental enhancement such as stream restoration, as well as trails, parks, and open space for the Board consideration.
- Provide flood protection to 1,664 parcels (1,378 homes, 160 businesses and 4 schools/institutions) downstream of El Camino Real from a 100-year flood (saving potential damages in excess of $47.9 million) by 12/30/2016.
- Prevent flooding of Middlefield Road and Central Expressway by 12/30/2016.
- Minimize the cost for maintenance.
- Floodwalls and levees north of U.S. 101
