Lower Rock River Watershed in Winnebago County Discovery

Post Date: January 31, 2012

As part of FEMA's Risk Mapping, Assessment, and Planning (Risk MAP) program, the Illinois State Water Survey (ISWS) will be working with communities to develop a more accurate understanding of their flood risk and help them plan for and communicate the risk. On behalf of FEMA, the ISWS hosted a Discovery meeting regarding flood risk within Winnebago County. The meeting was held Tuesday, January 25, 2011 at 1:00 PM in the REMAP Planning Room at 313 North Main Street, Rockford, IL.

A Discovery map and report have been prepared and may be downloaded along with the Discovery database.

Using information collected during the Discovery process, the ISWS identified streams for which an updated flood study and mapping were needed which would be of greatest use for communities. The ISWS held a second meeting with local officials on September 27, 2011 at 1:30 PM at the Rockford City Hall, 425 East State Street, Rockford, Illinois to review flood study needs. On the basis of this information, the ISWS has prepared and submitted to FEMA a proposed scope of work to prepare updated hydrologic and hydraulic studies and floodplain mapping.

Next Steps

When the scope of work is approved by FEMA, the ISWS, working with the USACE Rock Island District, will collect data and begin preparing hydrologic and hydraulic models. Once draft models are prepared, a Flood Risk Review Meeting will be held in the communities to examine the DRAFT results. Continuing local input is invited and encouraged.

After the Flood Risk Review Meeting, models and mapping will be refined and Preliminary Flood Insurance Rate Maps will be prepared and distributed for public comment and/or appeals.

Continued participation in the process of understanding flood risk is sought from various stakeholders such as community officials and their staff, storm water managers, floodplain and zoning administrators, engineers, GIS specialists, planners and economic development professionals, emergency responders, and natural resource experts. Teamwork among FEMA, ISWS, and the local stakeholders within the communities will be vital to the project's success in identifying, assessing, and communicating flood risks. The new flood risk products and maps produced through this project will help protect lives and property within communities.
