Ottawa sits at the meeting of the Illinois and Fox Rivers, a confluence that has shaped both the city’s growth and its flood exposure for generations. Property near either bank can fall within a FEMA Special Flood Hazard Area, where a surveyed Elevation Certificate becomes the document that ties a building’s height to the Base Flood Elevation. Ottawa serves as the LaSalle County seat, so many owners here also weigh floodplain permitting as they build or improve near the water.
A FEMA Elevation Certificate documents your building’s elevation relative to the Base Flood Elevation on the FEMA flood map. Insurers use it to rate flood policies and communities use it to confirm floodplain compliance; it can also support a Letter of Map Amendment (LOMA) to remove a structure from a flood zone.
The Pi Surveying process — clear, sealed, and ready for your project.
As the LaSalle County seat and home to roughly 18,840 residents across the Ottawa Township area, the city carries some of the county’s most defined riverfront floodplain because two rivers converge within it. A FEMA Elevation Certificate prepared by a licensed Illinois surveyor records your lowest floor elevation against the Base Flood Elevation, which flood insurers use to rate a policy and which a floodplain administrator reviews before issuing a permit. When a structure sits above the Base Flood Elevation, that same certificate supports a Letter of Map Amendment application to FEMA. Recorded documents for parcels here are handled by the LaSalle County Recorder of Deeds in Ottawa. For owners along the Illinois or Fox corridors, the certificate is often the single most useful measurement on file.
Because Ottawa lies where the Illinois and Fox Rivers meet, buildings near either bank can fall inside a mapped Special Flood Hazard Area, and an Elevation Certificate documents how the structure sits relative to the Base Flood Elevation for insurance and permitting.
It records surveyed elevations of the lowest floor, the lowest adjacent grade, and related reference points, then compares them to the Base Flood Elevation shown on the FEMA flood map for the property.
If the survey shows your lowest floor is at or above the Base Flood Elevation, the certificate gives your insurer the data to rate the policy accurately, and in some cases it supports a request to remove the property from the mapped floodplain.
