North Riverside lies in Proviso and Riverside townships near the Des Plaines River in western Cook County, 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.

North Riverside is a west-suburban village of about 7,400 residents across the Proviso and Riverside townships of Cook County, near the Des Plaines River. Its drainage belongs to the river system managed by the Metropolitan Water Reclamation District (MWRD). Much of the village is developed on moderately high ground, so Special Flood Hazard Areas concentrate near the river corridor and low-lying drainage rather than throughout the community. For a structure in a mapped zone, the certificate provides the surveyed elevations an insurer uses to rate coverage, documents compliance with North Riverside’s floodplain permits, and forms the basis of a Letter of Map Amendment (LOMA) when a building is documented above the flood elevation.
Official resources for North Riverside property owners
Areas nearer the Des Plaines River and low-lying drainage carry the clearest mapped exposure, while higher-ground parcels sit at lower risk.
The building’s lowest floor and reference elevations, the flood-zone designation, and the Base Flood Elevation, all tied to a vertical datum and certified by a surveyor.
If it shows your lowest floor is above the Base Flood Elevation, it can support a LOMA that removes the structure from the zone, which may end a mandatory-insurance requirement.
