Ahead of any purchase around Oakdale, look at the Monroe County flood zone map: FEMA's zone label affects insurance, permits and resale. What this county guide covers: locating a parcel on FEMA's map, decoding A, AE and X, and pairing it with the county Beacon site, at least around Tunnel City.
Where the Monroe County flood zone map lives
If you'd rather pan and zoom, try the National Flood Hazard Layer viewer, which draws the zones over aerial imagery, for land near Tunnel City included. Vacant ground around Cashton is still easy to locate: pan from the closest town and click the spot.
Getting to the right map
Your first stop is the Monroe County Beacon site; it maps every assessed parcel around Oakdale and Melvina. If you only know roughly where the land is, follow the nearest road on the aerial until the lines appear, then click inside the one you want, which applies near Angelo as much as anywhere. With a lot near Tunnel City, copy the parcel ID from that panel; each clerk in the county uses it to find the file.
Beyond the mapped zones
Small streams around Angelo may not have detailed mapping, so look for water marks and debris lines. Wet ground around Clifton is a separate issue from flood zones; the National Wetlands Inventory mapper shows mapped wetlands.
Who handles what
For assessment questions about property around Oakdale go to the county real property listing office, since that office keeps the assessment data. Building or septic questions for a lot near Norwalk go to planning, building or health offices, town or county, depending on location.
Decoding the flood zone labels
If you're looking near Cataract, A and V zones are Special Flood Hazard Areas, meaning a 1% or greater chance of flooding each year. If the land is near Farmers Valley, shaded Zone X marks moderate flood hazard, between the 1% and 0.2% annual chance floods; unshaded X is minimal risk.
Matching the zone to the lot lines
FEMA's map shows zones but not ownership, so check the Monroe County Beacon site too to confirm you have the right parcel near Norwalk.
Next door to Monroe County
Monroe County meets Jackson County, Juneau County, La Crosse County, and Vernon County, and each of those keeps its own parcel map. Ground near Tomah that runs to the line may be split across two assessors' files, so open the adjacent map as well. For a parcel near Angelo, our state page lists each bordering county map for Wisconsin.
Lenders and permits
If a building sits in a Special Flood Hazard Area and a federally regulated lender is involved, mandatory purchase rules apply where the community participates in the National Flood Insurance Program, for land near Kendall included. Remodeling a house in a zone near Melvina usually means extra permit review; call the permitting office early.
Recorded documents worth pulling
When the details count, request the recorded deed through the Register of Deeds; the parcel line is a drawing of it, and that holds around Sparta too. Long-held tracts around Melvina can sit on several deeds, so a title company is worth hiring before a purchase.
Using it on a phone
Most viewers work in a phone browser, useful out on a road near Melvina, but coverage can be spotty out of town. A printout of the tract near Kendall is a good backup.
Questions to ask before you buy
If the land is near Angelo, request for any Elevation Certificate before closing; getting a quote early avoids surprises.
Places you'll see on the map
Sparta holds the county offices, where most land records are kept. Smaller places on the map include Tomah, Cashton, Kendall, and Melvina, where town lots give way to larger tracts. Roughly 46,151 people live in Monroe County (Census Bureau estimate, 2023) across about 901 square miles. Monroe County dates to 1854, which matters when you trace an old farm's title.
Sections, lots and bearings
Wisconsin is laid out under the Public Land Survey System, so rural legal descriptions near Tunnel City cite section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though sections near Tunnel City can be irregular. Write down the legal description for the tract near Cashton for any title or survey request.
