Wilmette fronts Lake Michigan on the North Shore and is also drained inland by the North Branch of the Chicago River and the North Shore Channel. Both the lakefront and the interior channels contribute mapped flood exposure, and an Elevation Certificate documents floor elevation against the Base Flood Elevation for those properties.
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.
Wilmette, a lakefront village of about 28,200 residents in New Trier and Northfield townships, sits in northern Cook County along Lake Michigan. Inland drainage flows to the North Branch of the Chicago River and the North Shore Channel, both within the Metropolitan Water Reclamation District (MWRD) system. Flood exposure here is a mix of shoreline and interior-channel risk, with Special Flood Hazard Areas mapped in low-lying spots rather than across the whole village. Affected owners use the certificate for the surveyed elevations an insurer needs, for confirmation of compliance with Wilmette’s floodplain-permit requirements, and as the survey basis for a Letter of Map Amendment (LOMA) once a building is documented above the Base Flood Elevation.
Official resources for Wilmette property owners
Coastal-style exposure can apply near the shoreline, while interior flood risk follows the North Branch and North Shore Channel. Mapped zones identify exactly where each applies.
Owners whose parcels sit in a mapped flood zone, those told by a lender or insurer that one is needed, and anyone seeking to challenge a flood-zone designation through a LOMA.
The surveyor reads it from the effective FEMA flood data for your location and records it on the certificate alongside your measured building elevations.
