Ahead of any purchase around Edgerton, check the Beloit flood zone map: FEMA's zone label affects insurance, building rules and resale. In this Beloit guide: finding the address on FEMA's map, reading the zone codes, and pairing it with the Rock County ArcGIS parcel map.
Where the Beloit flood zone map lives
Flood zones come from FEMA's Flood Map Service Center: type an address near Janesville, and choose the dynamic map. Rural land near Footville with no street number is still easy to locate: zoom in from Interstate 39 then click the parcel area.
Getting to the right map
The official parcel map for this area is the Rock County ArcGIS parcel map, and it opens in a browser with no account. On ground around Evansville, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. For acreage around Brodhead, the parcel card typically gives the owner of record, acreage on the tax roll, a parcel ID and in many cases the last transfer.
Reading the legal description
Wisconsin follows the Public Land Survey System, which means a tract near Brodhead is described by section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though corrections make some sections near Orfordville odd-sized. Write down the legal description for the tract near Orfordville for any title or survey request.
Where Beloit fits in
Beloit is part of Rock County, Wisconsin, so its parcels are on the county's map. For acreage around Edgerton, city or town hall handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Acreage past the town limits near Evansville often answers to county rules instead.
What the zone letters mean
An AE label carries a published BFE, while plain Zone A does not; that elevation drives building rules near Evansville. For land near Footville, minimal risk is not no risk: according to FEMA, floods happen outside mapped zones too.
A short flood checklist
Ask the listing agent for any Elevation Certificate on the property near Brodhead; an insurance quote early keeps the budget honest.
Water near Footville
Small streams around Edgerton may not have detailed mapping, so walk the land after rain. Marshy spots near Orfordville can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
Matching the zone to the lot lines
FEMA's map shows zones but not ownership, so check the Rock County ArcGIS parcel map too to see exactly which lot near Evansville you're looking at.
Field tips
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Footville, so load it before you lose signal. A screenshot of the parcel near Brodhead with its ID is a good backup.
Which office to call
Questions about value or the owner field for land near Evansville are handled by the county real property listing office, which maintains the tax roll. Zoning, permits and septic questions near Footville need the planning or permitting office, and the answer depends on jurisdiction.
Insurance, lenders and building
For a home near Edgerton, an Elevation Certificate from a surveyor helps: it compares the building to the BFE. Remodeling a house in a zone near Evansville often needs a floodplain permit; call the permitting office before you plan.
A quick look at the area
Janesville holds the county offices, home to the main records offices. Other places on the map include Footville, Orfordville, and Brodhead. Roughly 164,278 people live in Rock County (Census Bureau estimate, 2023) spread over roughly 718 square miles. Rock County was organized in 1839, and some chains of title near Evansville are long.
What the map can't tell you
Listed acreage is an assessed number; only a licensed surveyor sets the real boundary for a parcel near Orfordville. Out toward Janesville, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Neighboring parcel maps
Rock County borders Boone County, IL, Winnebago County, IL, Dane County, Green County, and Jefferson County, and each of those keeps its own parcel map. Ground near Janesville that runs to the line can show up across two assessors' files, so check the adjacent map as well. For a parcel near Evansville, the Platbookmapper state page lists each neighboring county map across Wisconsin.
Beloit: common questions

Is my property near Brodhead in a flood zone?
Good question; look up the spot near Janesville in FEMA's National Flood Hazard Layer viewer; no account is needed.
Does the county parcel map show flood zones in Beloit?
For most people, a flood layer may appear in the Rock County ArcGIS parcel map layer list, though it can lag behind FEMA's current panels.

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.
