2019 Flood Protection Maintenance Projects

Zone 7 works hard to maintain the integrity of your flood protection system. This summer’s planned, current, and completed construction projects on Zone 7 flood control channels, as well as potential impacts to trails, can be viewed on this map. Please check back regularly for updates.

Update June 27, 2019: 

The Centennial Trail will be closed between the entrance onto Arroyo Mocho from West Las Positas Blvd to the bridge by Val Vista Park through mid-July. This is to allow for the construction of a bank slide repair by a U.S. Army Corps of Engineers contractor. Thank you for your patience while we make important repairs to your flood protection system.

Preliminary Lake Use Evaluation for the Chain of Lakes (2014)

The purposes of this 2014 study are to identify which potential lake uses may be more suitable for individual former quarries – especially where conflicting proposed alternatives uses may exist – and provide a framework for evaluating proposed uses as lakes are transferred to Zone 7 ownership. The evaluation generally does not preclude any given lake from distinct uses, but instead provides a tool for examining the benefits or impacts associated with a proposed use.
