For a more interactive look, try the National Flood Hazard Layer viewer, which draws the zones over aerial imagery. Vacant ground around Firestone is still easy to locate: zoom in from the nearest road and click inside the land.
Getting to the right map
Go first to the Weld County parcel viewer; it covers every tax parcel from Dacono to Frederick. With a lot near Lochbuie, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. For land near Brighton, a pop-up or side panel normally shows the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.
Low spots and local drainage
Creeks and ditches near Firestone aren't always studied in detail, so look for water marks and debris lines. Marshy spots near Frederick can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
Places you'll see on the map
Greeley serves as the county seat, home to the main records offices. Other places on the map include Lochbuie, Dacono, Brighton, and Frederick, each with its own cluster of lots. About 359,442 people call Weld County home (Census estimate, 2023) spread over roughly 3,985 square miles. Weld County was formed in 1861, and some chains of title near Platteville are long. Landmarks such as Pawnee National Grassland make handy reference points on the map near Brighton.
Where Fort Lupton fits in
Fort Lupton lies within Weld County, Colorado, so its parcels are on the county's map. For land near Firestone, the municipality handles things like zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Acreage past the city limits near Firestone generally answers to county rules, not municipal ones.
Decoding the flood zone labels
Zone AE includes a base flood elevation (BFE), while plain Zone A does not; surveyors near Frederick use that number. For property near Frederick, a shaded X area marks moderate flood hazard, roughly the 100- to 500-year range; plain X, or C on older maps, is minimal risk.
Offices that can help
For assessment questions about property around Platteville go to the County Assessor, since that office keeps the assessment data. Zoning, permits and septic questions near Dacono are for the local planning and health departments, town or county, depending on location.
Taking the map into the field
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Lochbuie, though signal can drop in rural spots. A saved image of the lot near Platteville and its lines is a good backup.
Reading the legal description
Colorado is laid out under the Public Land Survey System, so rural legal descriptions near Platteville cite section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though sections near Lochbuie can be irregular. Keep the legal description for land near Lochbuie for any title or survey request.
Parcel lines plus flood zones
If only part of a parcel near Firestone is shaded, the location of the house or building pad decides a lot.
What to request from a seller
Request about past flood claims on the property near Firestone; an insurance quote early keeps the budget honest.
Money questions tied to the zone
For a tract near Dacono, ask for an Elevation Certificate: it compares the building to the BFE. New construction in a floodplain near Firestone often needs a floodplain permit; check with the county or town building office early.
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. Acreage along the edge near Dacono may be split in two county records, so look at the neighboring map before you assume the acreage. Out toward Dacono, our state page lists every neighboring county map across Colorado.
