This Plan proposes a cooperative effort between FEMA and IDNR (Office of Water Resources and State Water Survey) to develop and maintain Illinois flood hazard data in a digital format. With funding from FEMA, IDNR proposes to continue modernization of flood maps over the next three years. To do this it will:
- Identify the best available digital base maps that meet FEMA standards,
- Convert Illinois flood hazard mapping to a digital, geo-database format (DFIRM2003),
- Help NFIP communities adopt the new maps, and
- Develop internal tracking to coordinate state flood mitigation projects, new hydrology and hydraulics reviews for flood insurance studies, and applications for letters of map change.
The funding request for FFY06-08 averages $5.2 million per year. These resources will permit IDNR to complete the job of modernizing maps for the remaining 76 counties in Illinois within the timeframe envisioned in the Multi-Year Flood Hazard Identification Plan.
