Public Safety Is the District’s Primary Concern
Many homes and businesses in Alameda County are located in floodplains. A floodplain is the natural area around a creek or river that floods periodically.
While the District works diligently to reduce the potential for flooding, heavy or prolonged rainfall causes increased flows in our creeks and channels. Flooding can still occur in some areas.

Could I Be at Risk of Flood from a Dam Failure?
Though you may not live near a dam, you could be affected if a dam breaks. Inundation maps are available for most large dams in the Bay Area. To see if your property could potentially be flooded, visit Flooding Maps and Information from the Association of Bay Area Governments (ABAG).
