Focus Groups

The City of Madison Engineering Division set locations, times, and dates for focus group meetings for the Dunn's Marsh Watershed. The meetings were requested by community members, and were open to the public, but the conversation was tailored to gathering more information on flooding issues in the meeting area. The focus groups looked further into the issues that caused flooding in the last few years specific to each meeting area.  The Engineering Division worked with alders, and residents to find a date, location and time that worked for the specific areas.

Report Flooding

If anyone has experienced flooding, and is willing to share with the City, please report it on the City's website. Even if a homeowner reported flooding to 2-1-1, FEMA, or a City official, the City needs standardized information to create stormwater models that show existing flooding conditions. The flood data helps the City prioritize different flood projects and future watershed studies. Please report any flooding you’ve experienced.
