Before an offer near Union Grove, check the Sturtevant flood zone map: a mapped flood zone changes insurance, building rules and resale. What this Sturtevant guide covers: the free FEMA tools, what each zone label means, when insurance is required and how to challenge a map that looks wrong.
The Sturtevant flood zone map: start here
Flood zones come from FEMA's Flood Map Service Center: search an address around Elmwood Park, then open the map view for that panel. Vacant ground around Elmwood Park is still easy to locate: zoom in from US Route 45 and click the spot.
Opening the official parcel viewer
Your first stop is the Racine County ArcGIS parcel map; it maps each assessed parcel around Union Grove and Elmwood Park. On ground around Yorkville, type a street address, an owner's name or a parcel number, then pick the result to center the map on it. In and around Union Grove, the record panel typically gives the owner of record, acreage on the tax roll, the parcel number and sometimes recent sales.
City limits and county records
Sturtevant sits in Racine County, Wisconsin, and the county assessor maps its lots. On ground around Caledonia, city or town hall handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Lots just outside the town limits near Elmwood Park usually follows county rules rather than the town's.
Offices that can help
If the acreage or value on a parcel near Union Grove looks off go to the county real property listing office, which maintains the tax roll. Questions about what you can build around Yorkville are for the local planning and health departments, and the answer depends on jurisdiction.
Decoding the flood zone labels
An AE label comes with a base flood elevation, and an unnumbered A zone has none; that elevation drives building rules near Union Grove. For property near Racine, minimal risk is not no risk: according to FEMA, many claims come from moderate- and low-risk areas.
Parcel lines plus flood zones
FEMA doesn't draw property lines, so open the Racine County ArcGIS parcel map next for the outline of the tract near Racine.
Legal descriptions in Wisconsin
Wisconsin is laid out under the Public Land Survey System, which means a tract near Racine 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 sections near Elmwood Park can be irregular. Copy the legal description from the record for the parcel near Racine for any title or survey request.
Beyond the mapped zones
Small streams around Caledonia may not have detailed mapping, so ask neighbors about past flooding. Wetlands near Racine can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
A quick look at the area
Racine serves as the county seat, where most land records are kept. Smaller places on the map include Mount Pleasant, Elmwood Park, and Yorkville, each with its own cluster of lots. Roughly 196,613 people call Racine County home (Census Bureau estimate, 2023) spread over about 333 square miles. Racine County was formed in 1836, and some chains of title near Caledonia are long.
Where the recorded documents are
The map is an index, not the title: deeds, subdivision plats and easements covering ground around Caledonia are filed with the Register of Deeds. Long-held tracts near Caledonia can sit on several deeds, and a title company earns its fee before a purchase.
A short flood checklist
Ask the seller whether the home has flooded on the property near Elmwood Park; getting a quote early avoids surprises.
What a flood zone means for a buyer
If a building sits in a Special Flood Hazard Area and a federally regulated lender is involved, flood insurance is generally required in communities in the NFIP, and that holds around Union Grove too. Remodeling a house in a zone near Elmwood Park can trigger elevation rules; ask the local floodplain administrator before you plan.
On site with the map
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Caledonia, though signal can drop in rural spots. A saved image of the lot near Caledonia and its lines keeps working without signal.
