Ashwaubenon, WI Environmental Rules: Erosion Control (2026)

Ashwaubenon adopted its construction-site erosion control ordinance under the authority Wisconsin gives villages in Wis. Stat. 354, and Section 5-9-770 supersedes any older village ordinance passed under Wis. Stat. 35. The Village Board designates the director of public works to administer and enforce it. A permit is required whenever a construction site disturbs 4,000 square feet or more of land; sites under that threshold still must meet the ordinance's baseline performance standards even without a permit, and the director can require a permit anyway if compliance, targeted performance standards, or protection of state waters calls for it.

One- and two-family homes built outside a larger development plan that disturb less than an acre are exempt from the Village's process and fall instead under the Wisconsin Department of Safety and Professional Services' rule, Wis. Admin. 125, not this ordinance. For permitted sites of an acre or more, the erosion and sediment control plan must hold the sediment load discharged in runoff to no more than 5 tons per acre per year, to the maximum extent practicable, using best management practices that keep soil off streets, out of storm inlets and out of waters of the state.

Permit holders must notify the director within 48 hours of starting work, inspect the site at least weekly and within 24 hours of any half-inch rain event, and keep written weekly inspection logs at the site. The director has 20 business days to approve or deny a complete application; silence beyond that period counts as approval. Permits run 180 days, renewable in further 180-day increments. Appeals of the director's decisions go to the Board of Appeals created under Chapter 17. The ordinance was last amended by Ord. No. 6-1-16 on June 28, 2016, building on Ord. No. O10-3-08 from October 28, 2008.
