If a legal description for land in Erie cites a lot number, you'll need the Erie plat map to make sense of it. Covered here for Erie: where to request a copy, plat versus tax map, and what to look for on the sheet.
The Erie plat map: start here
For land around Firestone, the deed or parcel record often names the subdivision and plat reference; use it to request a copy.
Where the parcel data lives
Go first to the Weld County parcel viewer; it covers each assessed parcel in the county, Thornton included. When a rural tract has no street number, zoom in from Firestone until the lines appear, then click inside the one you want. Write down the parcel ID while you have it open; each records desk in the county uses it to find the file.
Using it on a phone
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Dacono, though signal can drop in rural spots. A printout of the tract near Firestone helps when you meet an owner or agent.
Weld County in a few facts
Greeley serves as the county seat, where most land records are kept. Other places on the map include Dacono, Frederick, Firestone, and Northglenn, where town lots give way to larger tracts. About 359,442 people call Weld County home (Census estimate, 2023) on roughly 3,985 square miles. Weld County was formed in 1861, so old deeds can run back a long way. Features like Pawnee National Grassland help you orient on the aerial around Dacono.
When a plat changes
Lots near Dacono can be combined or reconfigured by a replat, so check for later filings; vacated streets or alleys also get recorded.
Limits of the parcel data
Listed acreage is an assessed number; only a licensed surveyor sets the real lines for a parcel near Northglenn. Around Thornton, records update in batches, so a deed recorded last month can take weeks to appear.
Erie, CO: the basics
Erie lies within Weld County, Colorado, and the county assessor maps its lots. With a lot near Frederick, 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 town limits near Northglenn usually follows county rules, not municipal ones.
Legal descriptions in Colorado
Colorado is laid out under the Public Land Survey System, which means a tract near Northglenn is described by section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though corrections make some sections near Northglenn odd-sized. Write down the legal description for the tract near Dacono for any title or survey request.
Two different maps
When the two disagree for a lot near Dacono, the recorded plat and a survey control.
Land on the county line
Weld County touches Adams County, Boulder County, Broomfield County, Larimer County, and Logan County, and each of those keeps its own parcel map. Ground near Northglenn that runs to the line can show up across two assessors' files, so look at the neighboring map before you assume the acreage. Around Frederick, our state page links every bordering county map for Colorado.
Details on the Erie plat map
Recorded easements around Frederick stay with the land when it sells; check the plat notes and any covenants.
Deeds, plats and who keeps them
The map is an index, not the title: recorded deeds, subdivision plats and easements covering ground around Longmont are kept by the County Clerk and Recorder. Out toward Dacono, have ready the instrument number listed on the parcel record and the lookup takes minutes.
Metes and bounds instead
Acreage around Northglenn outside a subdivision is often described by metes and bounds or survey description; look for a recorded survey for land near Longmont.
Getting a copy
The County Clerk and Recorder may have searchable images, while others require a visit or a request; copy fees are usually small.
Which office to call
Questions about value or the owner field for land near Northglenn belong with the County Assessor, since that office keeps the assessment data. Building or septic questions for a lot near Firestone are for the local planning and health departments, depending on whether the land is inside town limits.
