De Pere, WI: the basics
De Pere lies within Brown County, Wisconsin, and the county assessor maps its lots. Out toward Bellevue, the municipality handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Lots just outside the city limits toward Allouez usually follows county rules rather than the town's.
