Floodplain Development Requirements

All construction or fill within a floodplain requires a floodplain management permit. If you plan to build or grade within a federal or local floodplain, contact Water Resources staff at (916) 874-6851. Non-permitted floodplain construction or fill should be reported to (916) 875-RAIN.

All proposed new structures or substantial improvement of existing structures in a flood hazard area must be constructed at least 18 inches above the flood hazard elevation.
