2006 Arroyo de la Laguna Restoration Project
In Fall 2006, the Conservation Partnership implemented a streambank stabilization project along a 1,000-foot section of creek between Pleasanton and Sunol, a half-mile south of the Verona Road Bridge. The project was designed to reduce streambank erosion, establish vegetation, and improve riparian habitat. The Arroyo is important habitat for the Western pond turtle, a CA species of special concern. The project was a successful collaboration with San Francisco Public Utilities Commission, Zone 7 Water Agency, Alameda County Public Works Agency, the Dublin San Ramon Services District, and Alameda County Water District on this $620,000 pilot project. Hanford ARC was the contractor for the project.
In 2010, we partnered with San Francisco Public Utilities Commission to install additional vegetation and rootwads along the creek toe to provide aquatic habitat and additional erosion protection.
After a few dry years, the vegetation has really taken off and there has been a lot of sediment deposition on the constructed terrace and along the edge of the terrace between barbs. No additional trees from the top of bank have been lost since construction.
