The proposed action also involves shoreline flood protection components along Neptune Drive, primarily the construction of a berm and floodwall.
The proposed action consists of improvements to the Estudillo Canal, including expanding the capacity of the existing tidegate to allow for greater discharge flows, lowering a section of the southern canal bank to allow for temporary water storage in existing holding basins (“retention ponds”), and salt marsh modifications. The purpose of the proposed action is to reduce flood hazards.

Pursuant to Executive Order 11988 (Floodplain Management) and Executive Order 11990 (Wetlands Management) and FEMA’s implementing regulations at Title 44 of the Code of Federal Regulations Part 9, FEMA hereby provides interested parties with a notice of its intent to carry out an action affecting a floodplain and wetland. The proposed action would mitigate impacts from flooding by increasing flow capacity and redirecting flow in the Estudillo Canal, thus increasing shoreline protection at Neptune Drive to prevent coastal flooding from entering the project area. Department of Homeland Security’s Federal Emergency Management Agency (FEMA) intends to provide federal financial assistance under the Hazard Mitigation Grant Program to the Alameda County Flood Control and Water Conservation District in Alameda County, California to modify the Estudillo Canal by making improvements to the tidegate, lowering a portion of the canal, and creating a berm and floodwall along Neptune Drive.
