Dane County ECSM Manual

The Dane County erosion control and stormwater (ECSM) manual is designed to help landowners, developers and consultants meet the requirements of Dane County's Erosion Control and Stormwater Management Ordinance and aid in the erosion control and stormwater management permit process.

The manual includes information on why erosion control and stormwater management is needed, the standards that must be met, who needs a permit, and the steps to obtain an approved plan and permit. A list of approved management practices that will assist landowners and builders in selecting a combination of practices to meet the performance standards set by the ordinance. This is not an all-inclusive manual. Users will still need to refer to technical guidance manuals. Other practices not included in the manual may be used as long as they meet performance standards.
