Lyons sits directly on the Des Plaines River on Cook County’s western side, and that riverside position gives it genuine flood exposure. The village’s parcels near the river fall within mapped Special Flood Hazard Areas, and the community has a long history tied to the river valley. A FEMA Elevation Certificate underpins those steps, measuring the building’s elevation against the Base Flood Elevation.
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.

Lyons is a village of about 10,800 residents across Lyons and Riverside Townships in western Cook County, set along the Des Plaines River. Its drainage runs to the Des Plaines River system managed for regional stormwater by the Metropolitan Water Reclamation District (MWRD). Flood exposure is notable along the river corridor, so riverside parcels carry meaningful risk while higher ground away from the water carries less. In Lyons, an Elevation Certificate documents how a building stands against the Base Flood Elevation, giving insurers, floodplain-permit reviewers, and Letter of Map Amendment requests the survey data they depend on.
Official resources for Lyons property owners
The parcels nearest the Des Plaines River carry the most flood exposure, while higher ground away from the river is largely outside the mapped flood zones.
You would if the building sits in or near the mapped flood zone along the river, or if a lender or insurer requests one for coverage.
It can. If the certificate shows the lowest floor above the Base Flood Elevation, insurers can rate the policy on that verified height, often reducing the premium.
