The Central Valley is home to more than 1,600 miles of State-Federal levees. In many areas protected by this levee system, the risk of flooding is greater than the risk of fire.
Consider these facts:
- Since 1950, flood disasters have been declared in every California county at least ten times, with some counties having as many as 29 state and federal disaster declarations.
- Since 1983, Central Valley State-Federal project levees have been breached and overtopped more than 70 times.
- Local, State and Federal agencies are continuing to improve the State-Federal project levee system. But, there will always be some flood risk.
- Just one foot of flood water can cause more than $54,000 in damages to a $150,000 single-family home and its contents in the Central Valley; three feet of flooding could cause more than $93,000 in damages.
Entering an address on the Levee Flood Protection Zone maps gives an estimate of the maximum area for that address that may be flooded if a State/federal levee fails with flows at maximum capacity that may be reasonably conveyed.
