Before an offer near Dacono, pull up the Firestone flood zone map: the zone on that map shapes insurance, building rules and resale. This Firestone guide covers: locating a parcel on FEMA's map, reading the zone codes, and confirming the outline on the county map.
The Firestone flood zone map: start here
Start with FEMA's Flood Map Service Center: type an address near Berthoud, and choose the dynamic map. Rural land near Platteville with no street number is still easy to locate: zoom in from the nearest road then click the parcel area.
Where the parcel data lives
Property in and around Longmont can be looked up on the Weld County parcel viewer, a viewer that needs no account. Closer to Berthoud, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. With a lot near Longmont, the parcel card usually lists the owner of record, acreage on the tax roll, a parcel ID and in many cases the last transfer.
What to request from a seller
Ask the listing agent for any Elevation Certificate for the house near Dacono; an insurance quote early keeps the budget honest.
City limits and county records
Firestone sits in Weld County, Colorado, so its parcels are on the county's map. With a lot near Longmont, 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 toward Berthoud generally follows county rules rather than the town's.
What the zone letters mean
An AE label includes a base flood elevation (BFE), which plain A zones lack; surveyors near Berthoud use that number. Out toward Berthoud, a shaded X area marks moderate flood hazard, roughly the 100- to 500-year range; unshaded X means minimal mapped risk.
Parcel lines plus flood zones
FEMA's map shows zones but not ownership, so open the Weld County parcel viewer next to see exactly which lot near Frederick you're looking at.
Legal descriptions in Colorado
Colorado uses the Public Land Survey System, which means a tract near Frederick is described by 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 Mead vary in size. Keep the legal description for land near Berthoud for any title or survey request.
Getting your bearings
Greeley is the county seat, where most land records are kept. You'll also find Frederick, Mead, Dacono, and Platteville, each with its own cluster of lots. About 359,442 people call Weld County home (Census Bureau estimate, 2023) across roughly 3,985 square miles. Weld County was formed in 1861, and some chains of title near Mead are long. Landmarks such as Pawnee National Grassland are easy to spot when you zoom out from Berthoud.
Which office to call
If the acreage or value on a parcel near Platteville looks off are handled by the County Assessor, since that office keeps the assessment data. Questions about what you can build around Mead go to planning, building or health offices, and the answer depends on jurisdiction.
Lenders and permits
If you're looking near Frederick, ask for an Elevation Certificate: it compares the building to the BFE. Building or adding on near Longmont in a mapped zone usually means extra permit review; check with the county or town building office early.
A word on accuracy
Listed acreage is an estimate; only a licensed surveyor establishes the real lines on land around Longmont. Around Berthoud, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Backing up the map with records
The map is an index, not the title: deeds, subdivision plats and easements covering ground around Frederick are kept by the County Clerk and Recorder. Long-held tracts around Mead can go back through many deeds, and a title company is worth hiring on a real sale.
On site with the map
Most viewers work in a phone browser, useful out on a road near Platteville, so load it before you lose signal. A printout of the tract near Berthoud is a good backup.
Water near Platteville
Low-lying fields near Platteville may not have detailed mapping, so walk the land after rain. Wetlands near Berthoud can limit building even outside a flood zone; check the National Wetlands Inventory mapper for a first look.
Frequently asked
Is AE a high-risk flood zone in Firestone?
Both are high-risk zones, but only AE has a base flood elevation, which shapes building rules near Frederick.
How can I tell if a house near Mead is in a flood zone?
In most cases, look up the spot near Longmont in FEMA's National Flood Hazard Layer viewer; then confirm the parcel on the county viewer.
What is a LOMA around Longmont?
Good question; FEMA's LOMA process is the usual route when a building near Frederick sits above the base flood elevation; a surveyor's elevation data supports it.
Is flood insurance mandatory near Berthoud?
Good question; lenders generally require it for buildings near Mead in a Special Flood Hazard Area when the loan is federally regulated or insured; outside those zones it's your call.
Can I print the parcel map for land near Longmont?
Some viewers offer PDF export; include the record panel for the lot near Dacono.
