The District is responsible for many miles of levees across western Alameda County. A levee can be an earthen embankment or floodwall that contains, controls, or diverts the flow of water so as to provide protection from temporary flooding.

Many of the levees in Alameda County were built in the 1950s and 1960s when standards and building codes were different. Now, the District is taking new measures to address more rigorous federal requirements for levee certification and revised flood insurance maps. At the same time, the District is looking ahead at how its levees may function when the sea level rises due to climate change.
