Document Description
The California Department of Fish and Wildlife has executed Lake and Streambed Alteration Agreement EPIMS Notification No. EPIMS-CCA-52793-R3, pursuant to Section 1602 of the Fish and Game Code to East Bay Municipal Utility District.
The project is limited to retrofitting the Lafayette Reservoir Outlet Tower (Tower) and
conduits to address the seismic deficiencies under the Maximum Considered
Earthquake (MCE). The project seismic activities include shortening the Tower by
approximately 40 feet and modifying the existing spillway conduit (located within the
tower and embankment) and reservoir inlet/outlet conduit, by installing a 36-inch steel
pipeline and a 24-inch steel pipeline within the reservoir spillway and outlet, respectively. Construction access to facilitate modification of the tower and conduit will require temporary staging, modification of an existing access road and boat ramp, deployment of a floating work platform, and vegetation removal. Construction is expected to start in spring 2026, and to last approximately 18 months.
