2012 West Side Flood Study

In 2012, the City of Lockport engaged Manhard Consulting to complete a comprehensive flood study for the revision of the floodplain limits on the west side of Lockport, between the I & M Canal and the Des Plaines River. The study has been submitted to FEMA through the Illinois State Water Survey as a first step in seeking approval for a letter of map revision (LOMR). There are some outstanding projects that need to be completed before the map can be revised.

The attached Floodplain Exhibit shows the existing floodplain limits (blue) vs. the modified limits per the completed study (yellow).
