Posen sits in Bremen and Thornton townships in southern Cook County near Midlothian Creek and the Calumet drainage, where low-lying land falls inside mapped flood zones. For those parcels, 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.
The village of Posen, about 5,600 residents across the Bremen and Thornton townships of Cook County, lies in the southern suburbs near Midlothian Creek. Its drainage feeds the Calumet River system managed by the Metropolitan Water Reclamation District (MWRD). Portions of the village are low-lying, so Special Flood Hazard Areas follow the creek corridors and drainage rather than every block, while higher-ground areas carry less exposure. Owners in mapped zones rely on the certificate for the surveyed elevations an insurer uses to rate coverage, for compliance with Posen’s floodplain permits, and for the basis of a Letter of Map Amendment (LOMA) when a structure is documented above the Base Flood Elevation.

It follows Midlothian Creek and low-lying Calumet-system drainage; parcels on higher ground away from those corridors have limited mapped exposure.
If your parcel is in a mapped flood zone, yes; the data can affect flood-insurance rating and may support a LOMA that removes the structure from the zone.
The Elevation Certificate is the surveyed document of your building’s elevations; a LOMA is FEMA’s determination, based on that data, that a structure can leave the flood zone.
