A new map, detailing areas prone to street flooding during storms in Madison, Wisconsin, has been made available to the public. This map aims to assist residents by showing locations that may experience flash flooding, encouraging caution when driving and parking during extreme weather.

Developed by the City of Madison Engineering Division, this tool complements existing detailed watershed flood risk maps. It comes as part of the initiatives marking Wisconsin Severe Weather Awareness Week, observed from April 7 to April 11, 2025. The map is designed to raise awareness and prepare residents for the active weather season.

The City of Madison Engineering Division offers several resources to help the community understand different types of flooding, such as flash and lake level flooding. Flash flooding can occur when stormwater infrastructure is overwhelmed, while lake level flooding affects the Yahara chain of lakes when water input exceeds what the system can process. Guidelines for lake levels are set by the Department of Natural Resources and executed by Dane County.

Several resources are available to the public, including the City of Madison Engineering Division Historical Street Flash Flooding Map, the Watershed Study Map, and various resources from Wisconsin Emergency Management. Residents are encouraged to utilize the City of Madison’s Flooding Website for further information and to report flooding incidents.

More information and examination of the maps can be accessed through the resources offered by the City.
