Naperville straddles the DuPage River, whose main stem runs through the heart of downtown before continuing south toward Will County. Homes and businesses along the river and its adjacent low-lying blocks sit within mapped FEMA Special Flood Hazard Areas, which is exactly where an Elevation Certificate carries the most weight.
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.
Home to roughly 149,540 residents, Naperville spans Naperville, Lisle, Milton, and Winfield townships and is the largest municipality in DuPage County, whose seat is Wheaton. The DuPage River threads directly through the city, so a licensed surveyor’s Elevation Certificate documents how a structure’s lowest floor compares to the Base Flood Elevation on the countywide FIRM. That measured record lets an insurer rate a policy accurately, satisfies floodplain-permit conditions for building near the river, and forms the evidence base for a Letter of Map Amendment. Completed Elevation Certificates for Naperville addresses are recorded through the DuPage County Recorder of Deeds in the county seat.
If a Naperville parcel sits in or near the DuPage River’s mapped flood hazard area, an Elevation Certificate documents the building’s elevation against the Base Flood Elevation so flood insurance can be rated correctly and permit reviews can proceed.
It is a standardized FEMA form, completed by a licensed surveyor, that captures the elevations of a building’s lowest floor and reference features relative to the Base Flood Elevation shown on the effective flood map.
When it shows a structure is elevated at or above the Base Flood Elevation, the certificate can support a more favorable insurance rating and, in some cases, a Letter of Map Amendment removing the building from the mapped floodplain.
