Johnsburg sits along the Fox River near the Chain O’Lakes in northeastern McHenry County, so its riverfront and lakeside parcels carry substantial FEMA flood exposure. Areas set back on higher ground are lower risk. Given the flood-prone corridor, a surveyed elevation is important for any building near the water.
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.

Johnsburg, population about 6,355, is centered in McHenry Township with reach into Burton Township, within McHenry County. It lies along the Fox River near the Chain O’Lakes, and FEMA Special Flood Hazard Areas line that corridor, with county preliminary FIRMs released in 2024. A FEMA Elevation Certificate, completed by a licensed surveyor, documents a building’s elevation 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 Johnsburg parcels are recorded with the McHenry County Recorder in the county seat of Woodstock.
