Matteson lies in Rich Township in southern Cook County, drained by tributaries of Thorn Creek and the Calumet system that leave portions of the village in mapped floodplain. An Elevation Certificate documents how a building’s lowest floor compares to 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.
The Pi Surveying process — clear, sealed, and ready for your project.
Matteson is a southern suburb of roughly 19,100 residents within Rich Township, Cook County. Local drainage feeds Thorn Creek tributaries and the broader Calumet River system managed by the Metropolitan Water Reclamation District (MWRD). Much of the village sits on higher ground, so Special Flood Hazard Areas concentrate along the creek corridors and low-lying drainage rather than throughout the community. For a property in a mapped zone, the certificate provides the surveyed elevation figures an insurer uses to rate coverage, documents that construction complies with Matteson’s floodplain rules, and forms the technical basis for a Letter of Map Amendment (LOMA) when a building sits above the flood elevation.
