Zone 7 is planning a flood protection project along the Arroyo Mocho between Arroyo Road and Stanley Boulevard 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 is located between Arroyo Road and Holmes Street. This 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 Granada-Murrieta Reach extends from Holmes Street to Stanley Boulevard. In this reach, Zone 7 seeks to improve existing berms to minimize the potential of bank overtopping. 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.
