Union is a small village in southwestern McHenry County set in rural farmland within the Kishwaukee River watershed. Its FEMA flood exposure is limited and localized to small creek corridors. Most parcels sit on higher ground, and a surveyed elevation confirms any near a drainageway.
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.

Union, population about 551, sits in Coral Township within McHenry County. The surrounding rural land drains through small creeks in the Kishwaukee River watershed, and FEMA Special Flood Hazard Areas here are limited to those minor corridors, with county preliminary FIRMs released in 2024. A FEMA Elevation Certificate, completed by a licensed surveyor, documents a building’s lowest floor against the Base Flood Elevation so insurers can rate any required flood coverage, the village can confirm permit compliance, and owners can pursue a Letter of Map Amendment. Deeds for Union parcels are recorded with the McHenry County Recorder in the county seat of Woodstock.
Union’s flood exposure is limited to small creek corridors in the Kishwaukee watershed; most of the village lies outside the FEMA Special Flood Hazard Area.
If a property sits in or near a mapped flood zone, the certificate provides the surveyed elevations needed to rate insurance, meet permits, or challenge the mapping.
It compares your building’s lowest floor to the Base Flood Elevation on the FEMA map for your location.
