Northbrook spans Northfield and Wheeling townships, drained by the West Fork of the North Branch of the Chicago River and by Des Plaines River tributaries. Those watercourses place a share of parcels in mapped flood zones, where an Elevation Certificate ties a building’s elevation to the Base Flood Elevation for insurance and permits.
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.
Northbrook is a north-suburban village of roughly 35,200 people in the Northfield and Wheeling townships of Cook County. Its drainage feeds both the North Branch of the Chicago River and Des Plaines River tributaries, all within the Metropolitan Water Reclamation District (MWRD) service area. Most of the village occupies higher ground, so Special Flood Hazard Areas concentrate along these river branches and their tributaries rather than throughout the community. Where a structure sits in a mapped zone, the certificate gives an insurer the surveyed elevations to rate coverage, documents compliance with Northbrook’s floodplain permits, and provides the technical basis for a Letter of Map Amendment (LOMA) once a building is proven above the flood elevation.
Official resources for Northbrook property owners
The West Fork of the North Branch of the Chicago River and Des Plaines River tributaries carry the village’s mapped floodplain; higher-ground areas away from them have limited exposure.
Very. A licensed surveyor measures the elevations precisely and ties them to a vertical datum, because even small differences from the Base Flood Elevation can change how a policy is rated.
Yes. The village uses the certified elevation data to confirm that new construction or substantial improvements meet floodplain-management requirements.
