Where the Green Bay GIS map lives
Around Suamico, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
Opening the official parcel viewer
Property in and around Suamico appear on the Brown County ArcGIS parcel map, a viewer that needs no account. For a home near Bellevue, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. For land near Ashwaubenon, the parcel card typically gives the owner of record, assessed acreage, a parcel ID and sometimes recent sales.
Sections, lots and bearings
Wisconsin is laid out under the Public Land Survey System, which means a tract near De Pere is described by section, township and range. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though sections near Suamico can be irregular. Keep the legal description for land near Suamico before you request a deed or survey.
Printing and saving
Print or screenshot the parcel near De Pere with its ID visible, so you have it when calling an office.
Land on the county line
Brown County borders Calumet County, Door County, Kewaunee County, Manitowoc County, and Oconto County; every one of them runs a separate parcel map. A tract near the line by Suamico may show up across two assessors' files, so check the neighboring map too. For acreage around Ashwaubenon, the Platbookmapper state page links every bordering county map across Wisconsin.
Who handles what
Questions about value or the owner field for land near De Pere are handled by the county real property listing office, the office behind the parcel record. Questions about what you can build around Allouez need the planning or permitting office, and the answer depends on jurisdiction.
Troubleshooting the viewer
When the map won't open around De Pere, try a desktop browser or clear the cache; the Platbookmapper county page tracks the current link.
Using it on a phone
Most viewers work in a phone browser, useful out on a road near Suamico, but coverage can be spotty out of town. A printout of the tract near Ashwaubenon helps when you meet an owner or agent.
Green Bay, WI: the basics
Green Bay is part of Brown County, Wisconsin, so its parcels are on the county's map. As the county seat, Green Bay hosts the courthouse, so deeds and plats are filed in town. For acreage around Allouez, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Acreage past the city limits out by Suamico usually answers to county rules, not municipal ones.
Getting your bearings
Green Bay is the county seat, which is where the courthouse records live. Smaller places on the map include Allouez, Bellevue, Howard, and Ashwaubenon. About 271,417 people live in Brown County (Census Bureau estimate, 2023) spread over roughly 530 square miles. Brown County dates to 1818, and some chains of title near Suamico are long.
Search tips
Addresses are the easiest route inside Green Bay; owner names are usually entered last name first. For a parcel near Suamico, searching by parcel number never misses, and you'll find it on tax statements.
Beyond the parcel lines
If you're looking near Howard, look in the layer list for city limits, flood hazard, zoning or soils; availability varies.
Recorded documents worth pulling
The map is an index, not the title: deeds, plats and easements covering ground around Bellevue sit with the Register of Deeds. Inherited tracts near Bellevue can sit on many deeds, so a title company can sort it out before a purchase.
Owner, value and acreage
A parcel card near Howard normally gives owner, mailing address, assessed value and acreage.
A word on accuracy
Listed acreage is an assessed number; only a licensed surveyor establishes the real boundary on land around Howard. For a tract near De Pere, records update in batches, so a deed recorded last month might lag behind.
