Stormwater and Erosion Control Management

In 2014, the City of Monona obtained a grant from the State of Wisconsin Department of Natural Resources to develop a Stormwater Management Plan. This high level planning document will be used to help guide decision makers in selecting the best stormwater management solutions to improve water quality and meet the goals of the City's MS4 permit. View the plan.

In 2022 the City updated its Erosion Control and Stormwater Management Ordinance to meet the same standards set in the updated Dane County ordinance. These standards now include regulations for managing larger rain events and illicit discharges. With these changes came revisions to Monona's Erosion Control and Stormwater Management Permit Application.

The Federal Clean Water Act requires certain communities with stormwater systems that discharge to a lake or stream to obtain a permit for the discharge. Information on the requirements for an MS4 permit can be found at https://www.epa.gov/npdes.
