A flood plain is an area that will be inundated by a flood from a river, creek, ditch, lake, or other source of flooding.
100 Year Flood
A 100-year flood is the flood that statistically has a 1% chance of occurring each year.
A 100-year floodplain is the area that is referred to by FEMA as the Special Flood Hazard Area (SFHA). It is the area of a community where development must be regulated through a local ordinance conforming to the National Flood Insurance Program (NFIP).
FEMA is the Federal Emergency Management Agency. It is an independent agency of the federal government with the mission “to reduce loss of life and property and protect our nation’s critical infrastructure from all types of hazards through a comprehensive, risk-based, emergency management program of mitigation, preparedness, response and recovery.”
To determine if property is in a FEMA floodplain, we use the Flood Insurance Rate Maps (FIRMs) produced by FEMA to identify FEMA floodplain areas.
Permitting may be required in a FEMA floodplain area for any type of development including but not limited to fences, landscaping, excavating or structures.
The Floodplain Administrator will assist in matters concerning the FEMA floodplain and can be reached at the Public Works Office at 609 High Street or by phone at 785-594-6907.
