Full Breakdown

Under Winnebago County Code § 23.8-292(e), a truck stop's designated parking and other activity areas must be designed and located so that noise measured at the boundary line of an adjoining residential-zoned property does not exceed 60 decibels on the dB(A) scale between 10:00 p.m. and 7:00 a.m. The limit is one of several truck-stop-specific standards in § 23.8-292, alongside a 10-acre minimum lot size, U.S./state highway proximity, and a 22-foot cap on pump island canopy height. It is the only numeric decibel standard in the county's zoning code, and it applies only in towns that adopted the ordinance under Wis. Stat. § 59.69.

Violations & Fines

Exceeding the nighttime noise limit is a zoning violation under § 23.14-9: forfeiture plus prosecution costs, up to 6 months in jail for nonpayment, with each day of continued violation a separate offense.
