Your WaterFlood and Stream ManagementWatershed and Environment

Zone 7 is planning a flood protection project along the Arroyo Mocho between Arroyo Road and Holmes Street in Livermore. The primary purpose of this project is to reduce flood risk to the surrounding community during large storm events. The Medeiros Parkway reach represents one of the last remaining areas of natural floodplain within the urban center. Here, flood waters will be detained within the natural and enhanced floodplain and braided channels along Medeiros Parkway. The project also seeks to improve sediment management, enhance riparian and other habitat, and may augment local groundwater recharge. Although the project does not include construction of park facilities, the design will be compatible with current and anticipated future recreational uses in the area.

Project Schedule: Project planning, design, and permitting will continue through 2018. Construction is anticipated between April and October 2019.

Project Contact: Emily Moshier, Associate Engineer (925) 454-5035

Previous Work: In 2014, Zone 7 completed improvements on the Arroyo Mocho in the Stanley Reach, the one-mile stretch of creek between Murrieta Blvd. and Isabel Ave.


  • A draft Initial Study/Mitigated Negative Declaration (IS/MND) was prepared for the project and is available for public comment from April 25, 2018 to June 8, 2018. The IS/MND may be accessed here. Zone 7 values the public's input and as a result of the comments received has decided to revise the project. Zone 7 will continue to work collaboratively with the City of Livermore and the community on the project revisions. See the June 13, 2018 E-Newsletter for more information.
  • Zone 7 held a public meeting on February 13, 2108 to gather input on our design. Elements discussed include flood risk reduction, sediment management, the planting plan, and access to the site for public safety, maintenance, and recreation. In addition to Zone 7's presentation, officers from Livermore Police Department spoke regarding response to homeless activity. View the slides presented at the meeting.
