Dane County Land & Water Resources Department

Stormwater Management

Stormwater management involves measures taken to reduce or minimize the negative impacts of runoff of rainwater or melted snow from land disturbing and land development activities. Uncontrolled stormwater runoff can have adverse impacts on land and water. To reduce these impacts, Dane County Ordinance Chapter 14 (PDF) requires a permit for specific land disturbing activities that occur in Dane County. General permit information links:
