When a deed near Howard says lot and block, you'll need the Allouez plat map to make sense of it. What this Allouez guide covers: where to request a copy, how a plat differs from a parcel map, and what to look for on the sheet.
The Allouez plat map: start here
For a lot in Allouez, the deed or parcel record often names the subdivision and plat reference; use it to request a copy.
Pulling up a parcel
Your first stop is the Brown County ArcGIS parcel map; it includes each tax parcel from Howard to Green Bay. When a rural tract has no street number, pan along the nearest road until the lines appear, then click inside the one you want, which applies near Hobart as much as anywhere. Around Green Bay, write down the parcel ID while you have it open; each office in the county asks for it first.
On site with the map
The parcel map usually runs in a mobile browser, useful out on a road near De Pere, but coverage can be spotty out of town. A printout of the tract near De Pere keeps working without signal.
Amended plats
Lots near Hobart can be combined or reconfigured by a replat, search the index for replats of the same subdivision; street vacations show up in the records too.
Allouez and the county around it
Allouez is part of Brown County, Wisconsin, so its parcels are on the county's map. For a tract near Ashwaubenon, the municipality handles things like zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Lots just outside the city limits near De Pere usually falls under county rules rather than the town's.
Metes and bounds instead
Acreage around Ashwaubenon outside a subdivision is often described by metes and bounds or survey description; the deed and any recorded survey describe it instead.
A quick look at the area
Green Bay is the county seat, where most land records are kept. Smaller places on the map include Ashwaubenon, Bellevue, and De Pere. Around 271,417 people call Brown County home (Census Bureau estimate, 2023) on about 530 square miles. Brown County was organized in 1818, and some chains of title near Bellevue are long.
Who handles what
Questions about value or the owner field for land near Green Bay belong with the county real property listing office, which maintains the tax roll. Building or septic questions for a lot near Howard are for the local planning and health departments, and the answer depends on jurisdiction.
Reading the legal description
Wisconsin is laid out under the Public Land Survey System, so deeds around Ashwaubenon reference sections and townships. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though real sections near De Pere vary in size. Copy the legal description from the record for the parcel near Howard for any title or survey request.
Recorded plat or GIS layer
The tax map on the Brown County ArcGIS parcel map is a summary, while the recorded plat is the legal document.
Details on the Allouez plat map
Near Ashwaubenon, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
When a parcel crosses a boundary
Brown County borders Calumet County, Door County, Kewaunee County, Manitowoc County, and Oconto County, and each of those keeps its own parcel map. Acreage along the edge near Hobart may show up in two county records, so look at the adjacent map as well. Closer to Ashwaubenon, the Platbookmapper state page lists every neighboring county map across Wisconsin.
Limits of the parcel data
Parcel lines are drawn for taxes, not surveyed, so the edge of a yard near De Pere often sits some distance off the line on screen. Closer to Ashwaubenon, records update in batches, so a deed recorded last month might lag behind.
Backing up the map with records
The map is an index, not the title: deeds, subdivision plats and easements for land near Howard sit with the Register of Deeds. Closer to De Pere, have ready the book and page shown in the record panel so staff can find the deed fast.
Requesting the plat
Out toward Hobart, many recorder offices offer an online index, otherwise call or visit with the reference; copy fees are usually small.

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.
