De Pere, WI Environmental Rules: Vehicle Idling Restrictions (2026)

Section 14-89(1)(e) of the zoning ordinance folds a specific idling limit into the design requirements for commercial loading spaces. Rather than a standalone citywide anti-idling law, the rule attaches to every off-street loading space required under 14-89: the space must carry a posted sign prohibiting engine idling for more than 5 minutes. The requirement sits alongside the rest of the loading-space package, which requires 10-foot by 25-foot spaces with 15 feet of overhead clearance, on-site maneuvering rather than idling in the right-of-way, and a dustless all-weather surface approved by the public works director.

Because the idling limit is a posting requirement tied to loading docks and truck terminals rather than a general nuisance ordinance covering every parked car in the city, it targets the diesel trucks and delivery vehicles that use those bays, not residential driveways or downtown parking spaces. The development services director administers Article VIII citywide, and the general zoning enforcement provisions of Article XV apply: the city may issue a municipal citation under city code § 1-11 for a loading space that lacks the required signage or where idling is allowed to continue past the posted limit, and each day the violation remains uncorrected after notice counts as a separate offense.
