Prairie Grove is a small village in central McHenry County near the Fox River corridor, drained by creeks feeding that system. Its FEMA flood exposure is localized to those corridors, with some proximity to the river’s low ground. Much of the village sits higher, and a surveyed elevation identifies the parcels the maps affect.
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.
Prairie Grove, with roughly 1,963 residents, sits in Nunda Township within McHenry County near the Fox River. Local creeks drain toward the Fox, and FEMA Special Flood Hazard Areas here follow those corridors and the nearby river’s low ground, with county preliminary FIRMs released in 2024. A FEMA Elevation Certificate, prepared by a licensed surveyor, documents a building’s lowest floor against the Base Flood Elevation so insurers can rate flood coverage, the village can confirm floodplain-permit compliance, and owners can pursue a Letter of Map Amendment. Deeds for Prairie Grove parcels are recorded with the McHenry County Recorder in the county seat of Woodstock.
