When a deed near Berthoud says lot and block, the Johnstown plat map is where those numbers come from. In this Johnstown guide: where plats are filed, how a plat differs from a parcel map, and what to look for on the sheet.
Who keeps the Johnstown plat map
For land around Berthoud, the deed usually cites the plat; that makes the request quick.
The free map to start with
Your first stop is the Weld County parcel viewer; it maps every tax parcel in the county, Berthoud included. For a tract near Mead, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. In and around Evans, write down the parcel ID while you have it open; every clerk in the county asks for it first.
Getting answers from the right desk
If the acreage or value on a parcel near Gilcrest looks off go to the County Assessor, which maintains the tax roll. Questions about what you can build around Gilcrest go to planning, building or health offices, and the answer depends on jurisdiction.
Where the recorded documents are
For anything that matters, request the recorded deed through the County Clerk and Recorder; the parcel map near Platteville only summarizes it. If you're looking near Berthoud, have ready the document number from the tax record so staff can find the deed fast.
Reading the legal description
Colorado follows the Public Land Survey System, so deeds around Platteville reference sections and townships. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though sections near Platteville can be irregular.

Johnstown and the county around it
Johnstown sits in Weld County, Colorado, so its parcels are on the county's map. Out toward Mead, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Lots just outside the town limits out by Evans often falls under county rules, not municipal ones.

When a plat changes

Limits of the parcel data
The acreage figure is an assessed number; only a licensed surveyor establishes the real lines on land around Gilcrest. With a lot near Mead, owner names and values update on a schedule, so a deed recorded last month might lag behind.
When there's no plat
Acreage around Berthoud outside a subdivision is often described by metes and bounds or survey description; look for a recorded survey for land there.
