Flood Plain Administrator: Steve Warner

All low lying areas near rivers and streams are subject to flood hazards. Specific floodplain regulations are in force in the unincorporated areas of the county near Lander, Hudson, Dubois, and Riverton where the elevation of the 100 year flood has been determined. Construction is prohibited in some areas and restricted in others. Permits for construction must be obtained before the project is begun. In other areas of the county, flood hazards can be spatially defined but depth estimates are not available. It is extremely important that property owners and prospective buyers be informed of flood hazards and building requirements in designated floodplains before site preparation or construction is begun. Please contact the Fremont County Planning and Rural Addressing Department for further information. The municipalities of Lander, Hudson, Dubois and Riverton also have designated floodplains and building regulations specific to those areas.  To determine if your property is affected by a FEMA authorized flood rate map (FIRM) you can use the Flood Hazard Zone application on the Mapserver page of the County Website.
