The mission of the Floodplain Management Program can be broken down into three main components; the Community Assistance Program, flood mitigation assistance, and flood hazard mapping assistance to communities. Activities in the program are undertaken in conjunction with agreements between the Federal Emergency Management Agency (FEMA) and the State, which define floodplain management, flood hazard mapping and flood mitigation objectives.
The Floodplain Management Program was established in the Department of Conservation and Natural Resources, Division of Water Planning by the 1997 state legislature. The need for a statewide flood management program in Nevada became apparent when the damages from the 1997 New Years Flood on the Truckee River were assessed. In the Spring of 2001 the flood management program was transferred within the Department to the Division of Water Resources.
