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) 37.676709, -121.787062
Start Date Depends on availability of grant funding
End Date Depends on availability of grant funding
Location Description Livermore, California, Arroyo Mocho between Holmes Street and Stanely Boulevard
Holmes Street Sedimentation Basin and Granada/Murrieta Protection and Enhancement (Madeiros) Project (R3-4)

This project will construct a sedimentation basin just upstream of Holmes Street and will include creation of 0.95 acres of wetlands as environmental mitigation.  This project also includes levee construction and dedication of approximately 25 acres of land as 100-year floodplain park/open space to prevent development within floodplain.  Lastly, the project will conduct approximately 3,340 feet of riparian enhancement along both banks of Arroyo Mocho from Holmes Street sedimentation basin to Stanley Blvd, including along levees.  The project will also remove the existing Granada High School crossing, which is a potential fish barrier.
