Oak Forest sits in Bremen Township in southern Cook County, where Tinley Creek and Midlothian Creek in the Calumet drainage carve mapped floodplain through the community. For structures in those corridors, a FEMA Elevation Certificate records the floor elevation against the Base Flood Elevation to support 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.

Oak Forest is a southern suburb of roughly 27,500 residents within Bremen Township, Cook County. Its creeks, including Tinley Creek, drain toward the Calumet River system managed by the Metropolitan Water Reclamation District (MWRD). While much of the city sits on higher ground, the creek corridors and adjacent low areas fall inside Special Flood Hazard Areas. In those zones the certificate supplies the elevation figures an insurer uses to rate coverage, documents that construction complies with Oak Forest’s floodplain regulations, and forms the technical basis for a Letter of Map Amendment (LOMA) when a building is shown above the Base Flood Elevation.
Official resources for Oak Forest property owners
Land along Tinley Creek, Midlothian Creek and their tributaries carries the clearest mapped flood exposure, while much of the rest of the city is on higher ground.
The city’s floodplain rules require that new or substantially improved structures meet elevation standards, and an Elevation Certificate documents whether those standards are met.
It has no set expiration but should be updated if FEMA revises the flood map or if the building is altered, since either can change the recorded elevation relationship.
