A unique pilot project that Zone 7 Water Agency, Pleasanton's wholesale water retailer, undertook to enhance a section of the Arroyo Mocho flood control channel in Livermore was a recent finalist in the Association of California Water Agencies' 2015 Clair A. Hill Water Agency Award for Excellence.
The award program recognizes innovative projects by ACWA members in water resources management.
Zone 7's Arroyo Mocho Stanley Reach Riparian Restoration and Channel Enhancement Pilot Project is located adjacent to Stanley Boulevard between Murrieta Boulevard and Isabel Avenue.
Its goal is to demonstrate the feasibility of transforming an earthern trapezoidal channel into a vegetated stream reach exhibiting natural characteristics, while also maintaining its core functionality for flood protection and groundwater recharge.
The project's design facilitated stream channel enhancements, including 12 acres of increased riparian vegetation and removal of barriers to fish passages.
Other project benefits are expected to include enhanced habitat conditions (reduced stream temperatures and improved water quality), improved aesthetics and community education.
The revegetation work was accomplished through the Living Arroyos Program, which is a public-private partnership among Zone 7, the City of Livermore and the non-profit Urban Creeks Council. The program uses trained apprentices to oversee community volunteers.
"This volunteer program has been tremendously successful," said Zone 7 officials.
