Flood Plain Administrator: Steve Warner
All low lying areas near rivers and streams within Fremont County are subject to flood hazards.
Several highly populated areas in Fremont County are at risk of flooding, based upon historic events. To identify our community’s flood risk, the Federal Emergency Management Agency (FEMA) conducted a Flood Insurance Study in those areas. The data compiled during that study was used to create Flood Insurance Rate Maps (FIRMS), which provide an official depiction of the mapped flood hazards for properties within each community.
Based on the Flood Insurance Study, Fremont County Floodplain Zoning Regulations were developed for FEMA Mapped flood regions near Lander, Dubois, Hudson and Riverton where the 0.1 percent annual chance of flooding (100 year flood plain) has been determined.
Construction is restricted in all zones with a 0.1 percent annual chance of flooding and forbidden within the mapped Floodway.
In other areas of the County, flood hazards can be spatially defined but water depth and velocities have not been determined.
It is extremely important that property owners and prospective buyers be informed of flood hazards and building requirements in designated floodplains prior to building design or any construction.
How do I find out if my property lies within a flood hazard area?
The easiest way to see if your property lies within a flood hazard area is to turn on the ‘Flood Hazard Zones’ tab on the Fremont County Mapserver. This will highlight in blue the mapped 100 year event flood plain. It will also highlight in blue and red stripes the Floodway. This is an area where no construction can occur.
What should I do if my property is in a flood hazard area and I want to make improvements?
If your property is located within a mapped flood hazard area and you are planning to make changes (such as excavation or construction), you will need to fill out an Application for Floodplain Development through the Planning Department.
Am I eligible for flood insurance?
Fremont County participates in the NFIP, a program that provides means for property owners to financially protect themselves from flood risks. If you are a homeowner, renter, or business owner in unincorporated Fremont County, flood insurance coverage options from the NFIP are available to you whether your property lies within a flood hazard area or not.
Several towns within Fremont County also participate in the NFIP: Lander, Riverton, Dubois, Hudson and Shoshoni participate while Pavillion does not.
Detailed information on Flood Insurance coverage and limitations can be found on the Fremont County Emergency Management Agency tab on the website.
