Ahead of any purchase around Howard, look at the Ashwaubenon flood zone map: FEMA's zone label affects insurance, permits and resale. What this Ashwaubenon guide covers: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the Brown County ArcGIS parcel map.
The Ashwaubenon flood zone map: start here
Flood zones come from FEMA's Flood Map Service Center: type an address near Allouez, then open the map view for that panel. Vacant ground around De Pere is still easy to locate: zoom in from the nearest road then click the parcel area.
Pulling up a parcel
Go first to the Brown County ArcGIS parcel map; it maps each assessed parcel from Hobart to Howard. On ground around De Pere, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. If the land is near Howard, a pop-up or side panel normally shows the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
What to request from a seller
Ask the listing agent about past flood claims on the property near Green Bay; an insurance quote early avoids surprises.
Where Ashwaubenon fits in
Ashwaubenon lies within Brown County, Wisconsin, so its parcels are on the county's map. For property near Bellevue, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Land beyond the city limits out by Howard often follows county rules rather than the town's.
Water near Bellevue
Creeks and ditches near Allouez aren't always studied in detail, so walk the land after rain. Wet ground around De Pere is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
Brown County in a few facts
Green Bay is the county seat, where most land records are kept. You'll also find Allouez, De Pere, and Hobart, each with its own cluster of lots. Around 271,417 people call Brown County home (Census Bureau estimate, 2023) on roughly 530 square miles. The county was organized in 1818, and some chains of title near Allouez are long.
Backing up the map with records
The map is an index, not the title: deeds, subdivision plats and easements for land near Hobart sit with the Register of Deeds. If the land is near Howard, have ready the instrument number shown in the record panel so staff can find the deed fast.
Decoding the flood zone labels
An AE label comes with a base flood elevation, while plain Zone A does not; surveyors near Bellevue use that number. For acreage around Howard, a shaded X area marks moderate flood hazard, roughly the 100- to 500-year range; plain X, or C on older maps, is minimal risk.
Legal descriptions in Wisconsin
Wisconsin uses the Public Land Survey System, which means a tract near Allouez is described by section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though sections near Howard can be irregular. Copy the legal description from the record for the parcel near Bellevue for any title or survey request.
Limits of the parcel data
Listed acreage is an assessed number; just a licensed surveyor can set the real boundary for a parcel near De Pere. For land near De Pere, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Using it on a phone
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Bellevue, so load it before you lose signal. A screenshot of the parcel near Hobart with its ID is a good backup.
Use the county map alongside FEMA
FEMA doesn't draw property lines, so open the Brown County ArcGIS parcel map next to confirm you have the right parcel near Green Bay.
Insurance, lenders and building
For a parcel near Howard, get the Elevation Certificate if one exists: it records the building's elevation against the base flood. Remodeling a house in a zone near Allouez often needs a floodplain permit; ask the local floodplain administrator early.
Next door to Brown County
Brown County touches 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 Howard may show up across two assessors' files, so check the adjacent map as well. For a tract near Green Bay, the Platbookmapper state page links each neighboring county map across Wisconsin.
Quick answers
What if the flood map is wrong for my lot near De Pere?
Generally, FEMA's LOMA process is the usual route when a building near Green Bay sits above the base flood elevation; a surveyor's elevation data supports it.
What is a base flood elevation for land near Bellevue?
Good question; a BFE near De Pere tells builders how high the lowest floor should be; surveyors near Allouez use it often.
What does Zone AE mean near Hobart?
In most cases, both are high-risk zones, but only AE has a base flood elevation, so builders near Green Bay design to that elevation.
How often are flood maps updated near Howard?
In most cases, a new study can move a zone line near Bellevue; check the effective date on the panel.
Is the parcel map a survey in Ashwaubenon?
The map near Howard is approximate; a survey sets the real corners

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.
