Marseilles is an Illinois River town in eastern LaSalle County, built where the river and its dam have long been part of daily life. That riverfront setting places some properties within a FEMA Special Flood Hazard Area, and an Elevation Certificate is how owners document a building’s height against the Base Flood Elevation. For riverside parcels, it is a practical first step before insurance and permitting decisions.
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.
Marseilles, with about 4,845 residents in the Manlius Township area, sits directly on the Illinois River, which carries the mapped floodplain that matters most to local property owners. A licensed Illinois surveyor completes the FEMA Elevation Certificate by measuring the lowest floor against the Base Flood Elevation, giving flood insurers a factual rating basis and giving the floodplain administrator what is needed to review a permit near the river. When the survey confirms the building sits above the Base Flood Elevation, the certificate supports a Letter of Map Amendment to FEMA. Recording for Marseilles parcels goes through the LaSalle County Recorder of Deeds at the county seat in Ottawa. Properties on the higher ground back from the river generally face lower exposure.
Yes, Marseilles sits on the Illinois River, and the city’s Special Flood Hazard Areas follow that river corridor where the ground is low.
It records surveyed elevations for the lowest floor, adjacent grade, and reference points, along with the flood zone, Base Flood Elevation, and map panel details for the property.
You may, because an updated certificate is often requested when the flood map changes, the building is modified, or an insurer requires current data.
