What an Elevation Certificate Is
An elevation certificate is a standardized FEMA form documenting the elevation of a building relative to the Base Flood Elevation (BFE) in its flood zone. A licensed Professional Land Surveyor measures the lowest floor of the structure, the ground elevation at the foundation, and related data, then certifies the completed FEMA form. Insurance agents use it to calculate National Flood Insurance Program premiums; floodplain administrators use it to confirm permit compliance for new construction in flood zones.
Montana's River Flood Zones
Montana's flood risk comes almost entirely from spring snowmelt. The state's mountains accumulate snowpack through winter, and when temperatures rise in April and May, rapid snowmelt sends large volumes of water into the river systems. The result is predictable but significant annual flooding in valley communities located downstream of mountain drainage basins.
Major flood-risk rivers in Montana include:
- Yellowstone River through Billings and Laurel (Yellowstone County)
- Flathead River through Kalispell and Columbia Falls (Flathead County)
- Clark Fork River through Missoula (Missoula County)
- Missouri River through Great Falls (Cascade County)
- Gallatin and East Gallatin rivers through Bozeman (Gallatin County)
- Milk River through Havre (Hill County)
- Bitterroot River south of Missoula
Properties within the 100-year floodplain of these rivers are in Special Flood Hazard Areas and may require elevation certificates for flood insurance purposes.
Elevation Certificate Costs in Montana (2026)
Most residential elevation certificates in Montana cost $325 to $675. Properties in remote areas with long travel times from the surveying firm may run higher. The certificate does not expire, but FEMA recommends obtaining a new one if the property has been substantially improved or if a new flood map panel has been issued for the area.
Who Needs an Elevation Certificate in Montana
- Your mortgage lender requires flood insurance because your property is in a Special Flood Hazard Area
- Your insurance agent needs the certificate to calculate an accurate NFIP premium
- You want to apply for a Letter of Map Amendment (LOMA) to demonstrate your property should not be in the flood zone
- You are building or substantially improving a structure in a Montana river floodplain
- You are purchasing riverfront property and want to understand actual flood insurance costs before closing
What the Surveyor Measures
- The lowest floor elevation of your structure, including any basement, crawl space, or attached garage
- Ground elevation at the foundation and the lowest adjacent grade
- The building's latitude, longitude, and flood zone designation from the applicable FEMA map panel
- Flood opening details for any enclosures below the BFE
