When a deed near Baldwin says lot and block, you'll need the River Falls plat map to make sense of it. In this River Falls guide: where plats are filed, plat versus tax map, and the details that matter to buyers.
Who keeps the River Falls plat map
For a lot in River Falls, the deed usually cites the plat; bring that to the recorder's office or its online index.
Opening the official parcel viewer
Begin with the St. Croix County Beacon site; it maps each assessed parcel in the county, North Hudson included. For a tract near North Hudson, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. If you're looking near North Hudson, the record panel usually lists the owner of record, assessed acreage, a parcel ID and often a sale date.
Places you'll see on the map
Hudson holds the county offices, where most land records are kept. Smaller places on the map include Roberts, North Hudson, and Hammond, where town lots give way to larger tracts. About 96,763 people call St. Croix County home (Census estimate, 2023) on some 722 square miles. St. Croix County dates to 1849, so old deeds can run back a long way.
Where the recorded documents are
The map is an index, not the title: deeds, subdivision plats and easements covering ground around Roberts sit with the Register of Deeds. Older tracts near Roberts can go back through many deeds, so a title company is worth hiring on a real sale.
Replats and vacations
Lots near Hudson can be combined or reconfigured by a replat, search the index for replats of the same subdivision; vacated streets or alleys also get recorded.
Using it on a phone
The parcel map usually runs in a mobile browser, useful out on a road near Hammond, so load it before you lose signal. A printout of the tract near Hammond helps when you meet an owner or agent.
Legal descriptions in Wisconsin
Wisconsin uses the Public Land Survey System, so rural legal descriptions near Hudson cite section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though real sections near North Hudson vary in size. Copy the legal description from the record for the parcel near Hudson when you talk to a surveyor.
What the map can't tell you
Listed acreage is a tax-roll number; only a licensed surveyor can set the real lines for a parcel near Hammond. For a tract near Baldwin, records update in batches, so a deed recorded last month might lag behind.
City limits and county records
River Falls lies within St. Croix County, Wisconsin, and the county assessor maps its lots. For acreage around North Hudson, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, but the county runs assessment and recording. Land beyond the city limits out by Roberts generally answers to county rules instead.
When there's no plat
Acreage around North Hudson outside a subdivision is often described by metes and bounds or survey description; look for a recorded survey for land near Hammond.
When a parcel crosses a boundary
St. Croix County borders Washington County, MN, Barron County, Dunn County, Pierce County, and Polk County, all with their own assessor records. A tract near the line by North Hudson may be split across two assessors' files, so look at the adjacent map too. For a parcel near Roberts, the Platbookmapper state page lists each bordering county map for Wisconsin.
How a plat differs from the tax map
The tax map on the St. Croix County Beacon site is a summary, but the recorded plat is what the deed relies on.

Utility or drainage strips on a lot in River Falls can block a shed or pool; check the plat notes and any covenants.

Getting answers from the right desk
