Active Projects

Lafayette County

The Lafayette County Modernization project has distributed preliminary products to affected communities. A 90-day appeal/comment period covering these products ended September 20, 2019. No appeals or comments were received during this time.

This project has reached the Letter of Final Determination (LFD) date of June 17, 2020. What this means is the start of the 6-month adoption phase has begun. All communities in Lafayette County are affected. The current Flood Insurance Rate Map (FIRM) panels and Flood Insurance Study (FIS) will be superseded by these updated FIRMs and FIS and will need to be replaced in your local floodplain ordinance.

DNR has the materials listed below, to aid in updating your local floodplain ordinance. Please be on the lookout for a letter and/or email from DNR staff explaining this process. DNR staff are prepared to assist in 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 NR116, Wisconsin Administrative Code. The effective date of these products is December 17, 2020. Your floodplain ordinance must be adopted and approved by the DNR by this date to remain in good standing with the National Flood Insurance Program (NFIP).

Floodplain Ordinance Materials:

The DNR issued a new Model Floodplain Ordinance effective July 18, 2017 which meets the minimum requirements of the NFIP and Chapter NR116, Wisconsin Administrative Code.

Project Reference material

  • Resilience products [ZIP]: Areas of Mitigation Interest and Changes Since Last FIRM, developed as part of the Flood Risk Products to help identify changes in the floodplain and potential areas of mitigation.

Pierce County Physical Map Revision

FEMA is completing a physical map revision in the unincorporated areas of Pierce County and the Village of Spring Valley. This project is being managed by Rajendra Rachamalla with Atkins Global.

Walworth County's portion of the preliminary flood maps for the Upper Fox River Watershed are now available. They can be found at, FEMA Map Service Center [exit DNR].

There was an open house for the public to view the updated preliminary Flood Insurance Rate Maps on November 21, 2019, in Lake Geneva, WI. The updated preliminary Flood Insurance Rate Maps for Walworth County were on display for public review in preparation for the upcoming 90-day appeal period. During the 90-day appeal period citizens and floodplain professionals have the opportunity to submit an engineering study to request a change to the boundaries of the mapped floodplain. Representatives from local and state agencies are available to answer questions about flood risk, flood insurance, floodplain development regulations, the 90-day appeal period, and the process for floodplain mapping in Walworth County communities.

Kenosha County and Racine County

Kenosha and Racine Counties are in the preliminary map production phase for the Upper Fox Watershed. More information to follow as these projects progress.

Project History

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]

Discovery materials

Scope of work

Shapefiles for the final stream centerlines and survey locations as well as an overview map for the proposed scope of work (new detailed studies) can be downloaded. Additional information for contractors is also available.

Milwaukee River watershed

The regulatory products have reached the draft milestone and have been distributed to the communities. 

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. 

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 [PDF] 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 [PDF].

Kickapoo watershed

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 a 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.

Iron County

Iron County is a Map Modernization Project. The purpose is to update paper floodplain maps from the 1970s with better available data. Work maps and draft data have been completed and distributed to the affected communities for review.

A project delay of 12-18 months is now over. FEMA’s discussions regarding floodplain studies within tribal boundaries with the Lac du Flambeau Band of Lake Superior Chippewa Indians is at the stage where we can move forward with Preliminary map products. Once complete, preliminary products will be distributed to affected communities for review and comment in the coming months. Affected communities will be notified when this happens. A local officials meeting will then be scheduled to go over these preliminary products, answer questions, and discuss next steps. A public open house will be held in the evening.

Preliminary Maps for Iron County were released on July 8, 2020 and can be downloaded here: FEMA's Preliminary Data Search Tool [exit DNR]. The CCO (local officials) and public open were held via Zoom on November 4, 2020 and included presentations from both Wisconsin DNR and Wisconsin Emergency Management (WEM). Reference materials for the CCO meeting and Public Open are now available for viewing:

A 90-day appeal and comment period will begin in early 2021. During the appeal period anyone can submit comments and appeals requesting the preliminary maps be changes with supporting materials. FEMA will review all appeals and comments and make a determination of validity. DNR and FEMA are available to answer questions about the appeal/comment submission process.   

For questions, please contact Emily Szajna.

Shawano County

Shawano County is a Map Modernization Project. Hydrology and hydraulics are complete. Work maps and draft data were distributed to affected communities in November and are described further below. A Flood Risk Review and Resilience meeting was held on December 16, 2020 via Zoom to talk with local officials about these products. In addition, a 30-day comment period started on this date and ends on January 16, 2021. The regulatory products have reached the draft phase and have been distributed to the communities via an online through the Shawano County Proposed Data and Workmaps webmap.

Along with the regulatory products produced for the Shawano County modernization 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.

Work maps and a Flood Risk Database containing Changes Since Last FIRM (CSLF) and Areas of Mitigation Interest (AOMI) were discussed at the Flood Risk Review and Resilience Meeting. The draft work maps, which display the current effective and proposed revised floodplains, were viewed in the online map viewer and layers explained during the meeting. Information about the meeting follows.

Flood Risk Review/Resilience Meeting Material

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

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.

A project kick-off meeting was held on March 20, 2020 to present the process and timeline of the project. The current project phase is data development. Data was gathered from local, state, and federal sources to incorporate into the map products as base data. Survey is being completed and floodplains are being generated using engineering methods discussed at the kick-off meeting. Once this is complete draft data will be displayed on work maps showing proposed floodplains and other base data such as roads and political boundaries. A 30-day comment period will be provided on this draft data.

For questions, please contact Emily Szajna.

Florence County

Florence County is a Map Modernization Project. Hydrology and hydraulics have been completed for this project and floodplain linework created. Draft work maps and associated data have been produced and were available for review at a Flood Risk Review and Resilience meeting held in February 2020. A workshop covering floodplain management (flood insurance, ordinance requirements) and digital data access and use was done the same day.

The preliminary map products were distributed November 16, 2020. The next step will be holding a local officials’ meeting and public open house to discuss these products. Both meetings are scheduled for February 17th, 2021. Sometime after the open house, a 90-day comment/appeal period will start. Florence County will be notified by letter when this will occur.
