The Green Bay plat map: start here
For a lot in Green Bay, look for the plat book reference on the parcel record; that makes the request quick.
Getting to the right map
Property in and around Allouez appear on the Brown County ArcGIS parcel map, free to use and open without a login. On ground around Bellevue, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. For acreage around Howard, the parcel card typically gives the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
Amended plats
An amended plat may change lots around Suamico, so check for later filings; vacated streets or alleys also get recorded.
Brown County in a few facts
Green Bay serves as the county seat, which is where the courthouse records live. You'll also find Allouez, Bellevue, Howard, and Ashwaubenon, where town lots give way to larger tracts. About 271,417 people call Brown County home (Census Bureau estimate, 2023) spread over roughly 530 square miles. Brown County was organized in 1818, and some chains of title near Howard are long.
Before you lean on the lines
Acreage on the record is an assessed number; only a licensed surveyor can set the real boundary for a parcel near Howard. Out toward Suamico, owner names and values update on a schedule, so a deed recorded last month might lag behind.
On site with the map
Most viewers work in a phone browser, useful out on a road near Howard, but coverage can be spotty out of town. A screenshot of the parcel near Allouez with its ID keeps working without signal.
Green Bay, WI: the basics
Green Bay sits in Brown County, Wisconsin, which means parcel data comes from the county. Green Bay is also the county seat, handy when you need recorded documents. If the land is near Ashwaubenon, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Land beyond the city limits toward Ashwaubenon generally follows county rules rather than the town's.
Next door to Brown County
Brown County meets Calumet County, Door County, Kewaunee County, Manitowoc County, and Oconto County; every one of them runs a separate parcel map. Acreage along the edge near Ashwaubenon can be split across two assessors' files, so check the neighboring map too.

Plat map vs. parcel map
Where lines don't match in Green Bay, go with the plat and a surveyor's work.
Which office to call

Sections, lots and bearings
Wisconsin uses the Public Land Survey System, so rural legal descriptions near Bellevue cite section, township and range.

Copy the legal description from the record for the parcel near De Pere before you request a deed or survey.
Lots, blocks and easements
Closer to De Pere, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
When there's no plat

Getting a copy

Backing up the map with records

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
