The Federal Emergency Management Agency (FEMA) Flood Insurance Rate Maps for most of Nevada County were updated by FEMA on February 3, 2010. These maps indicate the approximate location of the floodplains for the major drainage courses within the County. Floodplains may be mapped for entire properties or portions of properties. The maps are available for viewing at the Planning Department Front Counter.
Constructing or placing fill within a floodplain requires a use permit. Additionally, zoning regulations establish a 100 foot non-disturbance buffer from the boundaries of a floodplain. If you propose construction in or near a floodplain you are advised to obtain a copy of the County Floodplain Ordinance and/or the Zoning Ordinance for reducing buffer areas. Copies are available at the Planning Department Front Counter.
