Marengo lies in southwestern McHenry County within the Kishwaukee River watershed, so parcels near the river and its tributaries carry FEMA flood exposure. Much of the city sits on higher farmland away from those corridors. A surveyed elevation is what distinguishes a low riverside lot from higher ground.
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.
Marengo, with about 7,568 residents, is anchored in Marengo Township with reach into Riley Township, within McHenry County. The Kishwaukee River drains this area, and FEMA Special Flood Hazard Areas follow the river and its tributaries, with county preliminary FIRMs released in 2024. A FEMA Elevation Certificate, prepared by a licensed Illinois surveyor, documents a building’s lowest floor against the Base Flood Elevation, giving insurers a basis to rate flood coverage, the city a way to confirm floodplain-permit compliance, and owners the evidence for a Letter of Map Amendment. Deeds for Marengo parcels are recorded with the McHenry County Recorder in the county seat of Woodstock.
Yes. Marengo lies in the Kishwaukee River watershed, and FEMA maps Special Flood Hazard Areas along the river and its tributaries, so nearby parcels carry flood exposure.
