Whats the difference between Alameda Creek, in Zone 5, and Old Alameda Creek, in Zone 3A?
The first waterway to be named Alameda Creek was one of several channels that crossed Zone 3A’s coastal plain to reach San Francisco Bay. From 1965 to 1975, a manmade flood control channel was constructed to dramatically increase flood protection for the area. This channel was termed the Alameda Creek Federal Project or “New Alameda Creek.” Today, the manmade channel is referred to as Alameda Creek, and the natural channel in Zone 3A is called “Old Alameda Creek.” For more information on Alameda Creek, visit the Alameda Creek Alliance.
