Planning, Development, & Sustainability

• Missoula County is working with the Federal Emergency Management Agency (FEMA) and the state Department of Natural Resources and Conservation (DNRC) to update floodplain maps for the Clark Fork River, the Bitterroot River and Rock Creek. The new maps are intended to provide more reliable and detailed information about areas prone to flood hazards. Updated floodplain maps will depict the latest, most accurate flood risk data, and will eventually replace the existing floodplain maps, which are based on data from the 1970s. For more information, please visit the Missoula County Voice Site
• This floodplain tool contains GIS information to help identify the Federal Emergency Management Agency (FEMA) designated 100-year floodplain in Missoula County outside of the Missoula City limits. For floodplain information within the City of Missoula, contact the City Floodplain Administrator at 552-6625.
• This GIS information does not imply that the subject property will or will not be free from flooding or damage. A property not in a designated 100-year floodplain may be damaged by a flood greater than predicted by FEMA or from a local drainage problem not shown on the FEMA Floodplain Map. Reliance on this GIS information does not create liability on the part of Missoula County or any Office or employee thereof from any damage that results from reliance on this information.
  
  Amendments to the floodplain maps are approved by FEMA through the Letter of Map Change (LOMC) process. Properties with LOMCs remain subject to Missoula County Floodplain Regulations but are exempt from federal flood insurance requirements. Properties with LOMCs available from Missoula County may be selected in the tool.
• Federal flood insurance may be required for improvements located in the designated floodplain. The lending institution is responsible for making that determination. Elevation Certificates may be used to determine the cost of flood insurance. Properties with elevation certificates available from Missoula County may be selected in the tool. If the subject property is located within the designated floodplain or a LOMC has been approved, a floodplain development permit may be required. Contact the County Floodplain Administrator at 258-4657 or by email at [email protected].
