Downers Grove is drained by St. Joseph Creek and other Salt Creek and DuPage River tributaries that wind through older neighborhoods. Where those creeks define FEMA Special Flood Hazard Areas, an Elevation Certificate becomes the document that ties a building’s floor to the regulatory flood level.
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.
With about 50,247 residents, Downers Grove covers portions of Downers Grove, York, Milton, and Lisle townships in DuPage County, whose administrative center is Wheaton. Local creeks feeding the Salt Creek and DuPage River systems create mapped floodplain corridors, and a surveyor’s Elevation Certificate records the lowest-floor elevation against the Base Flood Elevation for structures within them. The certificate is used to rate or reduce flood insurance, demonstrate compliance with floodplain-development permits, and support a Letter of Map Amendment where warranted. For Downers Grove parcels, the finished survey and its exhibits are filed with the DuPage County Recorder of Deeds.
Those along or near the village’s creeks and tributaries that appear inside mapped flood hazard areas on the DuPage County flood map are the most common candidates for an Elevation Certificate.
A plat of survey shows boundaries and improvements, while an Elevation Certificate specifically documents floor and grade elevations relative to the Base Flood Elevation on the FEMA form.
A Letter of Map Amendment is FEMA’s determination that a specific structure is not in the floodplain; elevation data from the certificate is the technical evidence that supports the request.
