Sponsoring Agency Zone 7 Water Agency
Subregions ('East Bay',)
Counties Alameda
Watershed Tributary Alameda Creek Watershed
Public or private land? ('Public', 'Private')
Location (lat/lon) 37.677873, -121.797348

End Date 10/15/2013
Location Description Stanley Boulevard, Iron Horse Trail, Arroyo Mocho, Isabel Avenue

This project takes an innovative approach to flood protection by using natural elements (e.g., stones, trees, and shrubs) to roughen the channel to compenstate the removal of existing energy dissipators. This project will also remove fish barriers through this reach of the Arroyo Mocho, while restoring and enhancing riparian habitat.

This project will remove the Dragon’s Teeth structure and four rip-rap style grade control structures in Arroyo Mocho between Murrieta Blvd and Isabel Avenue. The project will also roughen the channel using key and crest stones, native trees, and shrubs to compensate for the loss in energy dissipation structures, which will serve to develop a greater variety of aquatic ecosystem habitat. 

The project also includes approximately 6,000 feet of riparian enhancement  along both banks of the Arroyo Mocho flood control channel.

Flood Protection
This project improves the stream corridor for fish migration by removing known fish barriers, while also enhancing and restoring riparian habitat.
This project supports groundwater recharge, which will increase long-term drought preparedness by sustaining the local groundwater basin.
This stretch of the Arroyo Mocho is located alongside a future connector to the iron horse trail, which the City of Livermore intends to open to the public. The project also provides riparian habitat that will benefit ecosystem and recreational uses.
