How De Pere Handles Environmental Rules: A Practical Guide
De Pere maintains 93 local ordinances across all categories, and 3 of those deal specifically with environmental rules. Here is a breakdown of what the city actually requires, what is prohibited, and where De Pere falls on the strict-to-permissive spectrum compared to other cities.
Stormwater Management
De Pere bans putting anything but stormwater into its municipal storm sewer system (MS4) under City Code Sec. 29-4(a)(1), and bars illicit connections outright. The director of public works enforces the rule with warning notices, written orders and emergency shutoffs, and a violator faces a forfeiture of $1.00 to $1,000.00 per occurrence under Sec. 29-9(e).
Key details: What's banned: Any non-stormwater discharge to the MS4. Penalty: $1.00-$1,000.00 forfeiture per occurrence. Appeal deadline: 7 days to Board of Public Works. Spill-notice deadline: Next business day for non-hazardous releases. Enforcing officer: Director of Public Works.
Sec. 29-9(e) sets a forfeiture of $1.00 to $1,000.00 per occurrence, and every day a violation continues is a separate offense. The director can also recover attorney's fees, court costs, sampling and monitoring expenses under Sec. 29-12, and an uncorrected violation after appeal is treated as a public nuisance under chapter 78.
Erosion Control
Anyone starting land-disturbing construction in De Pere needs an erosion and sediment control permit from the building inspector before work begins, under City Code Sec. 42-10(a). The inspector must approve or reject a complete application within 20 business days, and violations draw a forfeiture of $200.00 to $1,000.00 per day under Sec. 42-14(f).
Key details: Permit required for: Any land-disturbing construction activity. Application review deadline: 20 business days. Permit duration: 180 days (extendable up to 180 more). Penalty: $200.00-$1,000.00 forfeiture per day. Enforcing officer: Building Inspector.
Section 42-14(f) sets a forfeiture of $200.00 to $1,000.00 plus the cost of prosecution for each violation, with every day a violation exists counted as a separate offense. The building inspector can also perform the required corrective work directly and bill the responsible party, with interest, and that unpaid amount becomes a special assessment collected on the tax roll.
Vehicle Idling Restrictions
De Pere's zoning ordinance caps truck engine idling at loading docks: every commercial loading space must be posted with a sign prohibiting engines from idling more than 5 minutes, part of the city's Article VIII loading-space design standards.
Key details: Idling limit: 5 minutes maximum. Applies to: Posted loading spaces. Governing section: § 14-89(1)(e). Enforcement: Municipal citation, § 1-11.
Failing to post the required no-idling signage at a commercial loading space, or allowing trucks to idle past the 5-minute limit once posted, is enforced by the development services director as a zoning violation. The city may issue a municipal citation under city code § 1-11, and each day the sign is missing or the limit is ignored after notice counts as a separate violation.
The rules around vehicle idling restrictions in De Pere lean permissive, but that does not mean anything goes.
The Bottom Line
De Pere's environmental rules rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming De Pere is broadly strict or permissive.
All of the above reflects De Pere's municipal code as of our last review. If you need specifics on fines, exemptions, or filing requirements, the detailed ordinance pages linked above have the full breakdown.
