Outagamie County, WI Environmental Rules: Stormwater Management (2026)

Adopted under Wis. Stat. § 59.693, Chapter 48 requires anyone starting a land-disturbing construction activity to obtain a post-construction runoff permit from the county zoning department before work begins. The permit application must include a stormwater management plan meeting the chapter's water-quality, peak-discharge, infiltration and protective-area performance standards, plus a maintenance agreement and fee. One- and two-family homes that aren't part of a larger development and disturb less than one acre are exempt, as are agricultural and silviculture non-point discharges. The rule applies within the county's zoning jurisdiction, not to activities in incorporated cities running their own program.
