Weighing a property around Mayville? A quick look at the Dodge County flood zone map shows whether the lot falls inside a mapped floodplain, and it costs nothing to check. What this county guide covers: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the county Beacon site around Beaver Dam Lake.
Where the Dodge County flood zone map lives
For a more interactive look, try the National Flood Hazard Layer viewer, which lets you click a spot and read its zone, which applies near Beaver Dam Lake as much as anywhere. A tract near Columbus without an address is still easy to locate: zoom in from Interstate 41 then click the parcel area.
Getting to the right map
Begin with the Dodge County Beacon site; it includes every assessed parcel around Columbus and Horicon National Wildlife Refuge. When a rural tract has no street number, pan along Interstate 41 until the lines appear, then click inside the one you want. For a home near Mayville, copy the parcel ID from that panel; every office in the county will want it.
Offices that can help
For assessment questions about property around Mayville are handled by the county real property listing office, the office behind the parcel record. Zoning, permits and septic questions near Horicon are for the local planning and health departments, and the answer depends on jurisdiction.
Sections, lots and bearings
Wisconsin is laid out under the Public Land Survey System, so deeds around Horicon National Wildlife Refuge 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 Horicon National Wildlife Refuge vary in size. Copy the legal description from the record for the parcel near Fox Lake when you talk to a surveyor.
Dodge County in a few facts
Juneau is the county seat, home to the main records offices. You'll also find Beaver Dam, Columbus, Fox Lake, and Hartford. About 88,231 people call Dodge County home (Census estimate, 2023) spread over some 876 square miles. Dodge County dates to 1844, which matters when you trace an old farm's title. Features like Beaver Dam Lake, Fox Lake, and Horicon National Wildlife Refuge help you orient on the aerial.
When a parcel crosses a boundary
Dodge County touches Columbia County, Dane County, Fond du Lac County, Green Lake County, and Jefferson County, all with their own assessor records. A tract near the line by Mayville can be split in two county records, so look at the neighboring map before you assume the acreage. In and around Horicon, our state page links every neighboring county map for Wisconsin.
What the zone letters mean
Zone AE comes with a base flood elevation, and an unnumbered A zone has none; surveyors near Horicon National Wildlife Refuge use that number. If you're looking near Ashippun, a low-risk label isn't a guarantee: FEMA notes that many claims come from moderate- and low-risk areas.
Lining it up with the parcel map
FEMA's map shows zones but not ownership, so open the Dodge County Beacon site next to see exactly which lot near Mayville you're looking at.
Lenders and permits
Closer to Fox Lake, get the Elevation Certificate if one exists: it records the building's elevation against the base flood. Remodeling a house in a zone near Beaver Dam often needs a floodplain permit; check with the county or town building office early.
A short flood checklist
Ask the listing agent whether the home has flooded on the property near Horicon National Wildlife Refuge; getting a quote early keeps the budget honest.
Field tips
Most viewers work in a phone browser, handy when you're parked on a road near Alderley, so load it before you lose signal. A screenshot of the parcel near Rubicon with its ID helps when you meet an owner or agent.
What the map can't tell you
Listed acreage is a tax-roll number; only a licensed surveyor establishes the real corners for a parcel near Beaver Dam Lake. Owner names and values update on a schedule, so a recent sale near Beaver Dam Lake can take weeks to appear.
Low spots and local drainage
Creeks and ditches near Hartford aren't always studied in detail, so look for water marks and debris lines. Wet ground around Juneau is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
Quick answers
How do I get a property removed from a flood zone around Hartford?
For most people, you can ask FEMA for a LOMA if surveyed elevations show the building near Rubicon is above the BFE, and lenders accept the result.
Is Zone X safe from flooding near Burnett?
In most cases, X zones around Rubicon are lower risk, not no risk, and floods still happen outside high-risk zones.
What is the difference between Zone A and AE around Horicon National Wildlife Refuge?
Short answer: both are high-risk zones, but only AE has a base flood elevation, which shapes building rules near Hartford.
Where do I find the BFE for a lot near Beaver Dam?
Generally, the base flood elevation is the water level expected in the 1% annual chance flood; surveyors near Alderley use it often.
How do I save a parcel from the viewer around Ashippun?
On ground around Beaver Dam Lake, some viewers offer PDF export; downloads of raw data vary by county.
