Risk MAP

Risk MAP (Mapping, Assessment and Planning) is the next phase in floodplain mapping now that the Map Modernization phase is complete.

  • New multi-year FEMA program using a watershed approach (vs. the county-wide approach used heretofore).
  • Studies will identify flood risk and provide products to communities to help reduce that risk.
  • Current funding provided for parts of projects in Upper Fox, Milwaukee, Kickapoo watersheds, Iron and Lafayette counties, and select flooding in Black River Falls, Lake Wausau, Fort McCoy, and Hoods Creek.

To view any of the projects preliminary maps, flood insurance study or data please go to FEMA's Preliminary Data Search Tool.

To download any of the non-regulatory products (Flood Risk Map, Flood Risk Report, or Flood Risk Data) please go to FEMA's Map Service Center. Watersheds that have had products produced are the Lower Wisconsin (HUC8 07070005), Upper Rock (07090001), Lower Rock (07090002), and Upper Fox(07120006).

Non-regulatory Flood Risk Products help communities gain a better understanding of flood risk and its potential impacts on communities and individuals. These products will also enable communities to take proper mitigation actions to reduce this risk.

Projects

Kickapoo watershed

The Kickapoo Watershed was chosen by the Federal Emergency Management Agency (FEMA) for the Discovery process, which kicked off in 2017. The goal of Discovery is to work with local communities to better understand local flood risk, mitigation efforts, and spark watershed-wide discussions about increasing resilience for flooding. It also includes evaluating the potential to update effective floodplain maps and mitigation planning needs for the basin. This report documents the coordination with stakeholders, and relevant data collected during the Kickapoo Watershed Discovery. This process concluded in September 2018 and the final Discovery Report, Map, and shapefiles are available for download.

Final discovery material

Reference material

Milwaukee River watershed

In February 2014, four Action Discovery meetings were held with communities in the Milwaukee Watershed to get a better idea of their mitigation and floodplain planning needs. As a result, a Final Discovery Report [PDF] was created to further reflect any additional comments by the communities and submitted to FEMA with suggested streams to be studied or included as leverage for data development. FEMA has approved some funding for data development as part of the Fiscal Year 2014 Budget. The details of this data development are still being worked out.

On May 16, 2013, Initial Discovery meetings were held in the Cities of Glendale and West Bend for the Milwaukee River watershed. The Milwaukee River watershed encompasses Dodge, Fond du Lac, Sheboygan, Milwaukee, Ozaukee, Washington and Waukesha counties and 39 incorporated communities. Local officials, engineers, planners and emergency managers participated in discussions about flood risk and hazard mitigation in their communities. The attendants also provided input about any areas of concern on streams they would like potentially restudied.

Additionally, a comment period was open until Monday, June 3, 2013 at the end of which all comments were compiled and re-evaluated by the DNR and captured in the Initial Discovery Report [PDF].

Upper (Illinois) Fox River watershed

In February 2014, four Action Discovery meetings were held with communities in the Upper Fox Watershed to get a better idea of their mitigation and floodplain planning needs. As a result, a Final Discovery Report [PDF] was created to further reflect any additional comments by the communities and submitted to FEMA with the impetus of receiving funding for Preliminary FIRMs in the next FY15 budget cycle. In FY12, FEMA provided funding for Hydrologic & Hydraulic modelling, resulting in the completion of detailed survey work for over 152 stream miles. The decision to fund DFIRM production will be decided in subsequent funding cycles.

On November 13, 2012, Initial Discovery meetings were held in the City of Waukesha and Village of Burlington for the Upper (Illinois) Fox River Watershed. The Upper Fox encompasses the counties of Kenosha, Racine, Walworth and Waukesha. Local officials, engineers, planners and emergency managers from around the watershed participated in the discussions regarding flood risk in their communities. The initial Discovery comment period was open until January 11, 2013 at which time all comments were re-evaluated by the DNR and presented in the Initial Discovery Report [pdf]
