Erosion Control & Stormwater Management

Stormwater is untreated runoff from rainfall and snowmelt. It flows across impervious surfaces, through fields and over construction sites, crossing municipal boundaries and carrying contaminants to our lakes and streams. These contaminants can include sediment, excess nutrients, heavy metals, oil, pesticides and bacteria. Because runoff is often warmer than our lakes and streams, it can raise their temperatures and degrade fish habitat.

The Dane County Lakes and Watershed Commission, after more than two years of careful and collaborative work, developed a stormwater management ordinance to control damaging stormwater runoff. During that time, the Commission turned for help, input, advice and expertise to a number of stakeholders throughout the county, including technical experts, local officials, builders and citizens.

The Ordinance went into effect on August 22, 2002, and was amended in fall 2005. Dane County administers the ordinance in unincorporated areas. Check the "Where to Apply for a Permit" document below to learn who administers these requirements within cities and villages in Dane County.

Effective January 2, 2007, Dane County's stormwater and erosion control programs are now all under one roof at the Land and Water Resources Department, located in the Lyman F. Anderson Agriculture and Conservation Center, Room 208, 5201 Fen Oak Drive in southeast Madison (phone 224-3730). Updated application forms and a completely updated and expanded Dane County Erosion Control and Stormwater Management Manual are found below.

The Water Resources Engineering Division also administers county erosion control and stormwater management requirements for the shoreland zone of navigable waters within unincorporated areas. The shoreland zone lies within 1,000 feet from the ordinary high-water mark of lakes, ponds or flowages and within 300 feet of the ordinary high-water mark (or landward side of the flood plain) of rivers and streams. See section 11.05 of the Dane County Code of Ordinances for these erosion and stormwater requirements (a link to Chapter 11 is found below). All other aspects of Chapter 11 are administered by Dane County Zoning.
