Sediment Reduction and Habitat Enhancement


The goals of the project are to:

(1) Decrease erosion in the upper watershed, thereby decreasing siltation of the reservoirs, and improving riparian habitat.

(2) Decrease streambank failures in the lower watershed, thereby decreasing soil erosion and downstream siltation to improve habitat for fish and wildlife.

(3) Provide alternative stream restoration strategies instead of traditional concrete lining of the watershed's streams and improve habitat for fish and wildlife.

Three sites were chosen to demonstrate alternative bioengineering techniques to repair streambank failures:

Palomares Creek (6395 Palo Verde Road, Castro Valley)
Eden Creek (22469 Eden Creek, Castro Valley)
Cull Creek (Cull Canyon Road, Castro Valley)
