Risk MAP Projects

Risk MAP (Mapping, Assessment and Planning) is the next phase in floodplain mapping.

The Risk MAP process includes:

  • A multi-year FEMA program using a watershed approach
  • High quality flood maps and information
  • Non-Regulatory tools to better assess the risk from flooding
  • Planning and outreach support to communities to help them take action to reduce flood risk

Please visit FEMA to learn more about RiskMAP.

To view and download effective maps, flood insurance studies, or data please visit FEMA's Map Service Center.

To view and download preliminary maps, flood insurance studies, or data, for active projects please visit FEMA's Preliminary Data Search Tool.

Active Projects

Door County

Floodplain Ordinance Materials

The DNR has a Model Floodplain Ordinance which meets the minimum requirements of the National Flood Insurance Program (NFIP) and Chapter NR 116, Wis. Admin. Code. All ordinance updates need to contain the minimum standards in the model. Please be on the lookout for an email from DNR staff explaining the update process. DNR staff are prepared to assist with the ordinance review and adoption process and explain state and federal regulatory requirements. Communities should have DNR staff review the draft local floodplain ordinance well before the ordinance is presented to the local governing body for adoption in order to ensure compliance with the NFIP and Chapter NR 116, Wis. Admin. Code. The Effective date of these products is May 8, 2024. Your floodplain ordinance must be adopted and approved by the DNR and FEMA by this date for your community to remain in good standing in the NFIP.

Maps

Note - Below are flood storage maps for Door County, Wisconsin. A flood storage map is part of the mapped floodplain that identifies the natural flood storage capacity of that watershed area. A shapefile has been sent to affected communities and will be available for viewing on the DNR Surface Water Data Viewer. If your community is listed on one of the flood storage maps below, flood storage language should be part of the community ordinance and the appropriate flood storage maps adopted.

For questions about the FIRM maps, please contact Nicole Metzger, Project Manager, nicole.metzger@atkinsglobal.com

For questions about the Flood Storage Maps, please contact Allison Kielar.

Countywide Projects

Bayfield County

Bayfield County floodplain maps are being updated countywide. Revised floodplains will be produced with better available data resulting in new engineered Zone A and redelineated detailed studies. A project kick-off meeting was held on March 19, 2020, to present the process and timeline of the project.

Douglas County

Project History

Douglas County floodplain maps are currently being updated. We are using better available data to produce newly engineered Zone A areas and update mapping along the Lake Superior coastline with data that FEMA has been working on as part of the Great Lake Coastal mapping effort. Coastal data will be incorporated into the mapping during the Preliminary phase of the project.

A project kick-off meeting was held on March 20, 2020, to present the process and timeline of the project. The data development phase is in progress. Data was gathered from local, state, and federal sources to incorporate into the map products as base data.

Flood Risk Review Meeting

Work maps and draft data were discussed at the Flood Risk Review Meeting held on January 25, 2023. An informal 30-day comment period started with this meeting allowing communities to provide input on the draft maps and data.

Langlade County

Langlade County is a Map Modernization Project where we are using better quality data to update floodplains and provide digital products to affected communities replacing the old, outdated paper maps. A project kick-off meeting was held on April 29, 2020, via Skype.

Project Kick-Off Meeting Materials

During this phase, the base map data and aerial photo are gathered from local and state sources and the floodplains are being updated using hydrologic and hydraulic methods. Once this is complete, draft work maps and data will be produced and shared with local officials.

Along with the regulatory products (FIRMs and FIS) created for the Langlade County modernization project, there is a set of non-regulatory products we will be generating. These non-regulatory 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.

For questions, please contact Allison Kielar.

Flood Risk Review/Resilience Meeting

Work maps and draft data were discussed at the Flood Risk Review and Resilience Meeting held on April 14, 2023. The draft work maps, which display proposed floodplains, are available for viewing.

Watershed Projects and Physical Map Revisions (PMR)

    Castle Rock Watershed (Adams, Clark, Columbia, Jackson, Juneau, Langlade, Marathon, Marquette, Monroe, Portage, Sauk, Shawano, Waushara, Wood)

    Discovery

    In September 2020, FEMA funded the DNR to begin the Discovery Phase of RiskMAP for the Castle Rock watershed.

    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. A kick-off meeting was held on May 25, 2021 and final Discovery meetings were held on August 4-5, 2022. The final Discovery Report and Map are available for download.

    Final Discovery Material

    Kickapoo Watershed (Crawford, Monroe, Richland, Vernon)

    In September 2020, FEMA funded the DNR to begin data development in the Kickapoo Watershed based on recommendations from the Discovery Report. This will include new and revised floodplain, draft maps, and changes since last FIRM map.

    Discovery

    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.

    Watershed Project History

    Prior to the development of these non-regulatory products, four Action Discovery meetings were held with communities in the Milwaukee Watershed to get a better idea of their mitigation and floodplain planning needs, in February 2014. As a result, a Final Discovery Report was created to further reflect any additional comments by the communities. This report was submitted to FEMA with suggested streams to be studied or included as leverage for data development. FEMA has approved and funded some of these projects 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.

    Along with the regulatory products produced for the Milwaukee River Watershed Mapping Project, there is a set of non-regulatory products. These non-regulatory 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.

    Non Regulatory products were delivered to the communities in August 2019. Work maps, Flood Risk Report, and Flood Risk Database were presented at Resiliency and Flood Risk Review Meetings on August 28, 2019 in Port Washington and West Bend. Printed work maps, which display the current effective and proposed revised floodplains, were available for review and comment at these meetings.
