DNR’s Database Of Remediation And Redevelopment Activities Can Help Local Governments

The Wisconsin Department of Natural Resources (DNR) maintains a public database of locations with remediation and redevelopment activities in Wisconsin.

The database is referred to as the DNR’s Bureau of Remediation and Redevelopment Tracking System on the web. A visual display of much of the information is available on the web-based mapping system, RR Sites Map.

Over 95,000 properties are in included in the database. Contaminated sites (i.e., the physical area of environmental contamination) affect properties in all counties and in approximately 95% of all cities, towns and villages in Wisconsin. The system includes links to numerous letters, reports and other information about the properties.

The DNR encourages local governmental units to use the database and RR Sites Map to identify contaminated and cleaned up properties within their communities. Information from the database and RR Sites Map may be useful to local governments when:

  • Identifying potential health and safety concerns in the community
  • Evaluating potential real estate transactions (e.g., conducting due diligence activities prior to the initiation of condemnation, tax foreclosure and other property acquisitions efforts)
  • Considering issuance of permits or approving plans for development – this includes understanding the status of contamination at sites where the cleanup is complete because residual contamination may affect the allowed uses and redevelopment options for a property, or require ongoing maintenance (e.g., caps over contaminated areas)
  • Reviewing proposed public works and utility projects to determine feasibility and whether contaminated material needs to be managed
  • Understanding the status of the property within the cleanup process, including what types of contamination is present, what needs to be done to satisfy regulatory requirements, and who is responsible for completing the necessary work

DNR staff are also available to help. Local governments can contact a brownfields specialist or schedule a “Green Team” meeting with DNR to discuss specific properties.
