Markham lies in Bremen and Thornton townships in southern Cook County, within the Calumet drainage where tributaries and low ground create mapped floodplain across parts of the city. An Elevation Certificate documents a building’s floor elevation against the Base Flood Elevation for insurance rating and floodplain 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.

Markham is a southern suburb of about 11,700 residents across the Bremen and Thornton townships of Cook County. Its drainage feeds the Calumet River system managed by the Metropolitan Water Reclamation District (MWRD), including tributaries that carry stormwater through the area. Portions of the city 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 needs, for confirmation of compliance with Markham’s floodplain regulations, and for the technical basis of a Letter of Map Amendment (LOMA) when a structure is proven above the flood elevation.

Tributaries of the Calumet system and low-lying drainage carry the city’s mapped floodplain; higher-ground parcels away from them have limited exposure.
Generally yes, unless FEMA revises the flood map or the building is altered, in which case an updated certificate may be needed to reflect the current situation.
If it documents your lowest floor at or above the Base Flood Elevation, the insurer can apply that margin when rating your policy, which may lower the premium.
