Updates To Remediation And Redevelopment Program Guidance And Publications Search Tool

The Department of Natural Resources (DNR) Remediation And Redevelopment (RR) Program Guidance And Publication Search Tool is currently undergoing maintenance that will result in a new look and web address, https://widnr.widencollective.com/portals/n3gjtfty/RRDocumentSearchPortal.

Starting June 30, 2023, the former web address will no longer be accessible and will result in a ‘page not found’ error. During the transition, both links will be active. Please update your bookmarks as soon as possible.

The update to the search tool includes a visual interface featuring publications, templates and forms as searchable collections. Multiple documents can be selected and downloaded at once and documents can be viewed in the web browser. Traditional search tools (i.e., general search and by subject/keyword) are available in the upper left-hand corner of each collection.

Links to other RR Program webpages, publications and documents should be unaffected. Contact DNRRRWebRequests@wisconsin.gov if you experience any issues.
