Lisle sits directly on the main stem of the DuPage River, which flows through the village and creates a well-defined floodplain. Structures near the river fall within FEMA Special Flood Hazard Areas where an Elevation Certificate is most valuable.
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.
Lisle has roughly 24,223 residents and spans Lisle and Milton townships in DuPage County, administered from the seat at Wheaton. With the DuPage River running through town, a surveyor’s Elevation Certificate documents a building’s lowest-floor elevation against the Base Flood Elevation on the effective map. That record supports accurate flood-insurance rating, floodplain-development permit compliance, and a Letter of Map Amendment where the structure is shown above the flood level. Lisle survey instruments tied to the DuPage River are recorded through the DuPage County Recorder of Deeds.
The DuPage River runs through Lisle and creates a mapped floodplain, so riverside parcels commonly need an Elevation Certificate for insurance and permitting.
The surveyor measures the elevations of the lowest floor and other reference points and ties them to the Base Flood Elevation on the FEMA form.
If it shows the building sits at or above the Base Flood Elevation, it can support a lower flood-insurance rate.
