Before an offer near Green Bay, look at the Suamico flood zone map: a mapped flood zone changes insurance, permits and resale. In this Suamico guide: finding the address on FEMA's map, decoding A, AE and X, and matching it with the county parcel viewer.
Getting started with the Suamico flood zone map
Start with FEMA's Flood Map Service Center: search an address around Pulaski, and pick the FIRMette or map view. Vacant ground around Pulaski can still be found: search the nearest road and click the spot.
Getting to the right map
Go first to the Brown County ArcGIS parcel map; it covers each assessed parcel around Pulaski and Howard. On ground around Howard, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a parcel near Howard, the record panel usually lists the owner of record, acreage on the tax roll, a parcel ID and often a sale date.
Who handles what
If the acreage or value on a parcel near Ashwaubenon looks off go to the county real property listing office, which maintains the tax roll. Questions about what you can build around Pulaski go to planning, building or health offices, and the answer depends on jurisdiction.
Where Suamico fits in
Suamico lies within Brown County, Wisconsin, which means parcel data comes from the county. If you're looking near Hobart, 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. Lots just outside the city limits out by Hobart generally falls under county rules, not municipal ones.
A short flood checklist
Request for any Elevation Certificate for the house near Green Bay; getting a quote early avoids surprises.
Zones on the Suamico flood zone map
Zone AE comes with a base flood elevation, and an unnumbered A zone has none; that elevation drives building rules near Hobart. For a home near Pulaski, a shaded X area marks moderate flood hazard, roughly the 100- to 500-year range; unshaded X means minimal mapped risk.
Limits of the parcel data
The acreage figure is a tax-roll number; just a licensed surveyor establishes the real lines for a parcel near Allouez. For a tract near Green Bay, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Sections, lots and bearings
Wisconsin is laid out under the Public Land Survey System, which means a tract near Pulaski 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 Hobart can be irregular. Copy the legal description from the record for the parcel near Hobart before you request a deed or survey.
Taking the map into the field
Most viewers work in a phone browser, which helps when you're standing on land near Howard, so load it before you lose signal. A saved image of the lot near Pulaski and its lines helps when you meet an owner or agent.
Water near Green Bay
Low-lying fields near Allouez may not have detailed mapping, so ask neighbors about past flooding. Wet ground around Ashwaubenon is a separate issue from flood zones; the National Wetlands Inventory mapper shows mapped wetlands.
Matching the zone to the lot lines
FEMA doesn't draw property lines, so pair it with the Brown County ArcGIS parcel map to confirm you have the right parcel near Howard.
Lenders and permits
In and around Allouez, an Elevation Certificate from a surveyor helps: it can change the insurance price a lot. Remodeling a house in a zone near Hobart can trigger elevation rules; ask the local floodplain administrator before you plan.
A quick look at the area
Green Bay is the county seat, home to the main records offices. You'll also find Howard, Pulaski, and Ashwaubenon, where town lots give way to larger tracts. Roughly 271,417 people call Brown County home (Census estimate, 2023) across some 530 square miles. Brown County was formed in 1818, and some chains of title near Ashwaubenon are long.
The paper trail behind a parcel
The map is an index, not the title: recorded deeds, plats and easements covering ground around Pulaski are filed with the Register of Deeds. Long-held tracts near Green Bay may go back through many deeds, and a title company can sort it out if money is changing hands.
Quick answers
How can I tell if a house near Hobart is in a flood zone?
Good question; FEMA's free map shows the zone for any spot near Green Bay; no account is needed.
What is a base flood elevation for land near Pulaski?
Usually, the BFE is printed in AE zones on FEMA's map; surveyors near Ashwaubenon use it often.
What does Zone AE mean near Green Bay?
It depends, but an AE zone has a 1% annual chance of flooding and a base flood elevation, which shapes building rules near Green Bay.
Is there a flood layer on the parcel viewer near Pulaski?
In most cases, a flood layer may appear in the Brown County ArcGIS parcel map layer list, though it can lag behind FEMA's current panels.
Where do I find the parcel number for land near Ashwaubenon?
It's the number the county real property listing office uses to track a tract near Pulaski; you'll see it in the viewer and on tax statements.

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.
