Rosemont sits in Leyden and Maine townships beside O’Hare and the Des Plaines River in northwest Cook County, where the river corridor places lower-lying parcels inside mapped floodplain. For those properties, a FEMA Elevation Certificate documents a building’s floor elevation against the Base Flood Elevation for insurance and permitting.
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.
Rosemont is a compact commercial village of about 4,000 residents across the Leyden and Maine townships of Cook County, adjacent to O’Hare International Airport and the Des Plaines River. Its drainage belongs to the river system managed by the Metropolitan Water Reclamation District (MWRD). The village is heavily developed for hospitality and business, so mapped Special Flood Hazard Areas concentrate in lower-lying areas near the river corridor rather than across the community. Where a structure sits in a mapped zone, the certificate provides the surveyed elevations an insurer uses to rate coverage, documents floodplain-permit compliance for construction, and forms the basis of a Letter of Map Amendment (LOMA) when a building is documented above the flood elevation.

The nearby Des Plaines River corridor creates mapped floodplain in the village’s lower-lying areas; higher, developed ground carries less exposure.
Yes. Any structure in a mapped flood zone, including hospitality and commercial properties, uses the Elevation Certificate to rate insurance and document floodplain compliance.
The surveyor reads it from the effective FEMA flood data for the parcel and records it on the certificate alongside your building’s measured elevations.
