Northfield lies in Northfield and New Trier townships along the West Fork of the North Branch of the Chicago River, where the river corridor places some parcels inside mapped floodplain. An Elevation Certificate documents a building’s lowest floor against the Base Flood Elevation for flood-insurance rating and permit compliance.
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.
Northfield is a north-suburban village of about 5,800 residents across the Northfield and New Trier townships of Cook County, along the West Fork of the North Branch of the Chicago River. That river, part of the drainage system managed by the Metropolitan Water Reclamation District (MWRD), creates Special Flood Hazard Areas along its corridor through the village. Much of the community sits on higher ground, so exposure concentrates near the river and its tributaries rather than village-wide. Affected owners use the certificate for the surveyed elevations an insurer needs, for confirmation of compliance with Northfield’s floodplain-permit process, and as the basis of a Letter of Map Amendment (LOMA) once a structure is documented above the Base Flood Elevation.

The West Fork of the North Branch of the Chicago River carries the village’s mapped floodplain; higher-ground areas away from it have limited exposure.
When FEMA revises the flood map for your area or when you substantially alter the building, since either can change the recorded elevation relationship.
It gives the insurer your building’s lowest floor height relative to the Base Flood Elevation, the key figure used to rate the flood policy.
