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

Active Projects

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 affected communities for review.

Preliminary Maps and Appeal Process

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 house 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:

The Iron County project has had Preliminary products distributed to affected communities. A 90-day appeal/comment period covering these products ended August 11, 2021. No appeals or comments were received during this time.

Adoption Phase

This project has reached the Letter of Final Determination (LFD) date of November 23, 2022. This is the start of the 6-month adoption phase for affected communities. The current Flood Insurance Rate Map (FIRM) panels and Flood Insurance Study (FIS) will be superseded by these updated FIRMs and FIS and the references to these will need to be updated in your local floodplain ordinance.  

Floodplain Ordinance Materials

The DNR issued a new Model Floodplain Ordinance in March 2022 which meets the minimum requirements of the National Flood Insurance Program (NFIP) and Chapter NR 116, Wis. Admin. Code. Use the maps and ordinance adoption resources below when 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 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 23, 2023. 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 - Above are flood storage maps for Iron County and the City of Montreal. 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 made available on the DNR Surface Water Data Viewer

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]

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 [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].

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.
