For any lot around Milliken, the Windsor GIS map shows parcel boundaries plus basic tax data. In this Windsor guide: which viewer to open, how to search it, and what to double-check with records.
Opening the Windsor GIS map: start here
Closer to Greeley, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
Pulling up a parcel
Your first stop is the Weld County parcel viewer; it maps every tax parcel around Eaton and Greeley. If the land is near Milliken, type a street address, an owner's name or a parcel number, and the matching parcel lights up. For land near Milliken, the record panel typically gives the owner of record, acreage on the tax roll, a parcel ID and often a sale date.
Which office to call
Anything recorded against property around Greeley are with the County Clerk and Recorder, often with an online index. Questions about what you can build around Ault are for the local planning and health departments, town or county, depending on location.
Where Windsor fits in
Windsor lies within Weld County, Colorado, and the county assessor maps its lots. Around Johnstown, city or town hall handles matters such as zoning, permits and utilities within town limits, while the county keeps the tax map. Land beyond the city limits out by Eaton usually falls under county rules instead.
Deeds, plats and who keeps them
The map is an index, not the title: deeds, plats and easements covering ground around Ault are kept by the County Clerk and Recorder. Out toward Severance, have ready the book and page shown in the record panel and the lookup takes minutes.
Taking the map into the field
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Ault, but coverage can be spotty out of town. A saved image of the lot near Severance and its lines keeps working without signal.
Printing and saving
Save a screenshot of the lot near Johnstown and its record panel, which helps later when you ask the assessor or a title company.
Land on the county line
Weld County meets Adams County, Boulder County, Broomfield County, Larimer County, and Logan County, all with their own assessor records. Ground near Johnstown that runs to the line can be split across two assessors' files, so open the neighboring map as well. If the land is near Milliken, our state page links every bordering county map for Colorado.
Weld County in a few facts
Greeley is the county seat, where most land records are kept. You'll also find Severance, Eaton, and Johnstown. About 359,442 people live in Weld County (Census Bureau estimate, 2023) across about 3,985 square miles. Weld County was organized in 1861, and some chains of title near Ault are long. Features like Pawnee National Grassland help you orient on the aerial around Milliken.
Searching the map
Vacant ground near Milliken may lack an address, so zoom in from the nearest road and click the outline. On ground around Johnstown, searching by parcel number never misses, and you'll find it on tax statements.
Beyond the parcel lines
If the land is near Milliken, layer lists often include zoning, flood zones, city limits, school districts or contours; not every viewer has them all.
When the map won't load
When the map won't open around Eaton, switch browsers or turn off pop-up blockers; links occasionally change, and our directory page keeps the current one.
What the record panel tells you
Recent sales on nearby lots near Greeley are a useful starting point; an appraiser is the real authority.
What the map can't tell you
The acreage figure is an assessed number; only a licensed surveyor establishes the real lines on land around Greeley. Around Greeley, records update in batches, so a deed recorded last month can take weeks to appear.
Reading the legal description
Colorado follows the Public Land Survey System, so rural legal descriptions near Ault cite section, township and range. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though real sections near Eaton vary in size. Keep the legal description for land near Ault before you request a deed or survey.

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.
