Elevation Certificates in La Crosse County
An elevation certificate documents your building's elevation relative to FEMA's Base Flood Elevation and is required by lenders for federally backed mortgages on properties in Special Flood Hazard Areas. La Crosse County sits along the Mississippi River, which is one of Wisconsin's most significant sources of flood risk. The county has substantial FEMA SFHA-designated areas, particularly in the city of La Crosse and Onalaska.
Mississippi River Flood Risk in La Crosse County
The Mississippi River has a broad, historically active floodplain in La Crosse County. FEMA's flood maps designate significant Special Flood Hazard Areas in the low-lying sections of La Crosse near the river, the floodplain areas of Onalaska near the Black River confluence, and along the river corridor to the north in Holmen and the townships extending toward Trempealeau County.
Spring flooding on the Mississippi is a regular occurrence in this part of Wisconsin. High-water years push the river onto floodplain properties that sit relatively close to the Base Flood Elevation. This makes elevation certificates both a common lender requirement and a useful insurance management tool for property owners in the affected areas.
What an Elevation Certificate Documents
A licensed surveyor visits your property, measures the lowest floor elevation and other required reference points, and completes the official FEMA elevation certificate form. The certificate shows whether your building is above or below the Base Flood Elevation on FEMA's maps, which determines how your National Flood Insurance Program premium is calculated.
In the city of La Crosse, established survey benchmarks are accessible, making the elevation connection part of the process relatively efficient. For properties farther from established benchmarks or in rural coulee areas of the county, more fieldwork may be required to establish the connection.
Using a Certificate to Manage Insurance Costs
La Crosse County property owners in SFHA zones who are elevated above the Base Flood Elevation can document that with a certificate and potentially qualify for significantly lower NFIP premiums. In high-risk zones, annual premiums can reach $2,000 or more, making a $400 to $700 elevation certificate a worthwhile investment that pays back quickly.
