Destined for DFIRMs
Criteria for our displayed studies:
- Must have a finalized contract for work
- Publicly funded
- Submitted voluntarily
This site shows those areas where the Illinois State Water Survey's CHAMP group is either performing engineering studies, collecting information, or incorporating new engineering data submitted by others as Physical Map Revisions (PMRs) to the Digital Flood Insurance Rate Maps, as well as, other publicly funded studies.The Web application can be a tool to guide those seeking Letters of Map Revision (LOMRs) through MT-2 form submission. If there are LOMR studies or other flood hazard studies ongoing in or near the identified streams on our application, please contact our staff to verify precise locations to avoid redundancy.
At this time, we cannot display an individual study's progress, but inquires can be made to our staff regarding timelines. Once fully approved, these studies will be incorporated into the Federal Emergency Management Agency's effective Digital Flood Insurance Rate Maps (DFIRMS), and removed from this map application.
