When a listing near Afton mentions a lot number, look up the Cottage Grove plat map it refers to. In this Cottage Grove guide: where plats are filed, plat versus tax map, and what to look for on the sheet.
Getting started with the Cottage Grove plat map
For a subdivision near Hastings, look for the plat book reference on the parcel record; use it to request a copy.
The viewer Washington County publishes
Begin with the Washington County ArcGIS parcel map; it includes every assessed parcel in the county, Landfall included. For a tract near Woodbury, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. For a tract near Afton, a pop-up or side panel typically gives the owner of record, assessed acreage, the parcel number and often a sale date.
Metes and bounds instead
Acreage around Lake St. Croix Beach outside a subdivision may have no plat at all; look for a recorded survey for land near Hastings.
Offices that can help
For assessment questions about property around Lake St. Croix Beach are handled by the County Assessor, which maintains the tax roll. Building or septic questions for a lot near Lake St. Croix Beach are for the local planning and health departments, depending on whether the land is inside town limits.
Washington County in a few facts
Stillwater serves as the county seat, home to the main records offices. You'll also find Newport, Hastings, Woodbury, and Afton, each with its own cluster of lots. About 278,936 people live in Washington County (Census estimate, 2023) spread over roughly 385 square miles. Washington County was formed in 1849, and some chains of title near Newport are long. Features like Afton State Park are easy to spot when you zoom out from Woodbury.
Legal descriptions in Minnesota
Minnesota is laid out under the Public Land Survey System, so deeds around Lake St. Croix Beach reference sections and townships. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though real sections near Lake St. Croix Beach vary in size. Write down the legal description for the tract near Woodbury when you talk to a surveyor.
Using it on a phone
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Hastings, but coverage can be spotty out of town. A printout of the tract near Lake St. Croix Beach helps when you meet an owner or agent.
Replats and vacations
An amended plat may change lots around Afton, search the index for replats of the same subdivision; street vacations near Woodbury show up in the records too.
Cottage Grove, MN: the basics
Cottage Grove lies within Washington County, Minnesota, and the county assessor maps its lots. Around Woodbury, city or town hall handles matters such as zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Lots just outside the city limits toward Hastings often falls under county rules rather than the town's.
A word on accuracy
Acreage on the record is an estimate; only a licensed surveyor sets the real boundary on land around Afton. Out toward Lake St. Croix Beach, records update in batches, so a deed recorded last month might lag behind.
Recorded plat or GIS layer
The Washington County ArcGIS parcel map draws parcels for taxes, but the recorded plat is what the deed relies on.
Lots, blocks and easements
For land near Newport, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
Recorded documents worth pulling
When the details count, pull the recorded deed through the County Recorder; the parcel map near Lake St. Croix Beach only summarizes it. Older tracts near Landfall can go back through several deeds, and a title company can sort it out if money is changing hands.
Getting a copy
Closer to Woodbury, many recorder offices offer an online index, while others require a visit or a request; copy fees are usually small.
Land on the county line
Washington County meets Anoka County, Chisago County, Dakota County, Ramsey County, and Pierce County, WI; every one of them runs a separate parcel map. Ground near Hastings that runs to the line may be split in two county records, so look at the neighboring map too. Closer to Landfall, our state page lists every neighboring county map for Minnesota.
