Before you buy or build near Horicon, pull up the Waupun flood zone map: FEMA's zone label affects insurance, building rules and resale. In this Waupun guide: finding the address on FEMA's map, reading the zone codes, and pairing it with the Dodge County Beacon site.
Getting started with the Waupun flood zone map
Flood zones come from FEMA's Flood Map Service Center: search an address around Fox Lake, and choose the dynamic map. A tract near Brownsville without an address can still be found: pan from the closest town and click inside the land.
Where the parcel data lives
Your first stop is the Dodge County Beacon site; it maps each tax parcel around Beaver Dam and Kekoskee. For property near Fox Lake, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. On ground around Burnett, a pop-up or side panel usually lists the owner of record, assessed acreage, a parcel ID and often a sale date.
Waupun and the county around it
Waupun lies within Dodge County, Wisconsin, so its parcels are on the county's map. In and around Horicon, the municipality 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 town limits out by Kekoskee generally answers to county rules instead.
Getting your bearings
Juneau is the county seat, where most land records are kept. Other places on the map include Burnett, Fox Lake, Kekoskee, and Brownsville, where town lots give way to larger tracts. About 88,231 people call Dodge County home (Census estimate, 2023) on some 876 square miles. Dodge County dates to 1844, and some chains of title near Burnett are long. Features like Beaver Dam Lake, Fox Lake, and Horicon National Wildlife Refuge are easy to spot when you zoom out from Beaver Dam.
Recorded documents worth pulling
On ground around Beaver Dam, the map is an index, not the title: deeds, plats and easements for parcels in the county sit with the Register of Deeds. Closer to Beaver Dam, bring the instrument number shown in the record panel so staff can find the deed fast.
Sections, lots and bearings
Wisconsin uses the Public Land Survey System, so deeds around Beaver Dam 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 Fox Lake vary in size. Keep the legal description for land near Burnett for any title or survey request.
Limits of the parcel data
Acreage on the record is an estimate; only a licensed surveyor sets the real corners for a parcel near Brownsville. Out toward Burnett, owner names and values update on a schedule, so a deed recorded last month may not show yet.
What the zone letters mean
With a lot near Brownsville, any A or V zone are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any year. For acreage around Kekoskee, shaded Zone X marks moderate flood hazard, roughly the 100- to 500-year range; plain X, or C on older maps, is minimal risk.
Beyond the mapped zones
Creeks and ditches near Kekoskee aren't always studied in detail, so walk the land after rain. Wetlands near Beaver Dam can limit building even outside a flood zone; check the National Wetlands Inventory mapper for a first look.
Use the county map alongside FEMA
FEMA's map shows zones but not ownership, so open the Dodge County Beacon site next to confirm you have the right parcel near Fox Lake.
Money questions tied to the zone
For a structure inside an A or V zone and a federally regulated lender is involved, flood insurance is generally required in communities in the NFIP, whether the land is near Kekoskee or elsewhere in the county. Building or adding on near Fox Lake in a mapped zone usually means extra permit review; check with the county or town building office before you plan.
Questions to ask before you buy
Ask the listing agent for any Elevation Certificate for the house near Brownsville; getting a quote early keeps the budget honest.
Taking the map into the field
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Fox Lake, though signal can drop in rural spots. A screenshot of the parcel near Fox Lake with its ID keeps working without signal.
