Elevation Certificates in Silver Bow County
An elevation certificate is an official 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 NFIP flood insurance premiums; floodplain administrators use it to confirm compliance for new construction in flood zones.
Flood Risk in Silver Bow County
Silver Bow County's flood risk is relatively low. Butte sits at high elevation on the Continental Divide. Some properties near Silver Bow Creek, which runs through the historic Butte mining district and is part of the Clark Fork Superfund cleanup area, may have FEMA flood zone designations in the lower creek corridor. Historic mining drainage patterns affect local hydrology in ways not typical of other Montana counties. Property owners with riverfront or low-lying properties should confirm their flood zone status with their insurance agent and lender before assuming they are outside a Special Flood Hazard Area.
Elevation Certificate Costs in Silver Bow County (2026)
Most residential elevation certificates in Silver Bow County cost $300 to $575. Properties in remote areas with longer 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 Silver Bow County
- 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 floodplain
- You are purchasing property near Butte and want to understand actual 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
The surveyor certifies the completed FEMA form. Keep the original with your property records and share it with any future buyer, as it stays valid with the property as long as the building and flood map have not changed significantly.
