Before an offer near Greystone, pull up the Moffat County flood zone map: the zone on that map shapes insurance, building rules and resale. What this Moffat County guide covers: finding the address on FEMA's map, reading the zone codes, and confirming the outline on the county map.
Getting started with the Moffat County flood zone map
If you're looking near Craig, flood zones come from FEMA's Flood Map Service Center: enter the street address, then open the map view for that panel. Rural land near Dinosaur National Monument with no street number is still easy to locate: zoom in from the nearest road and click inside the land.
The free map to start with
Go first to the Moffat County ArcGIS parcel map; it maps each assessed parcel around Routt National Forest and Dinosaur National Monument. If you only know roughly where the land is, pan along the nearest road and click the parcel itself, for land near Greystone included. If you're looking near Browns Park National Wildlife Refuge, write down the parcel ID before closing the panel; each records desk in the county will want it.
Field tips
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Browns Park National Wildlife Refuge, though signal can drop in rural spots. A screenshot of the parcel near Hamilton with its ID keeps working without signal.
Zones on the Moffat County flood zone map
Zone AE comes with a base flood elevation, and an unnumbered A zone has none; builders around Browns Park National Wildlife Refuge design to it. With a lot near Browns Park National Wildlife Refuge, a shaded X area is moderate risk, between the 1% and 0.2% annual chance floods; plain X, or C on older maps, is minimal risk.
Water near Blue Mountain
Small streams around Dinosaur National Monument aren't always studied in detail, so ask neighbors about past flooding. Marshy spots near Dinosaur National Monument can limit building too; check the National Wetlands Inventory mapper for a first look.
A quick look at the area
Craig holds the county offices, home to the main records offices. Other places on the map include Dinosaur, Maybell, Blue Mountain, and Elk Springs, where town lots give way to larger tracts. Around 13,327 people call Moffat County home (Census estimate, 2023) across roughly 4,743 square miles. The county was formed in 1911, which matters when you trace an old farm's title, at least around Elk Springs. Features like Browns Park National Wildlife Refuge help you orient on the aerial.
Who handles what
If the acreage or value on a parcel near Blue Mountain looks off belong with the County Assessor, the office behind the parcel record. Zoning, permits and septic questions near Maybell go to planning, building or health offices, depending on whether the land is inside town limits.
Neighboring parcel maps
Moffat County meets Rio Blanco County, Routt County, Daggett County, UT, Uintah County, UT, and Carbon County, WY, all with their own assessor records. Acreage along the edge near Craig can show up in two county records, so open the neighboring map before you assume the acreage. Out toward Dinosaur National Monument, our state page links every bordering county map across Colorado.
Reading the legal description
Colorado uses the Public Land Survey System, so rural legal descriptions near Routt National Forest cite section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though sections near Dinosaur National Monument can be irregular. Copy the legal description from the record for the parcel near Dinosaur National Monument when you talk to a surveyor.
Lining it up with the parcel map
FEMA doesn't draw property lines, so check the Moffat County ArcGIS parcel map too to confirm you have the right parcel near Dinosaur.
Deeds, plats and who keeps them
For anything that matters, get the recorded deed from the County Clerk and Recorder; the viewer just points to it, for land near Elk Springs included. On ground around Dinosaur National Monument, have ready the document number shown in the record panel so staff can find the deed fast.
What to request from a seller
Ask the seller for any Elevation Certificate for the house near Greystone; an insurance quote early avoids surprises.
What a flood zone means for a buyer
For land near Craig, ask for an Elevation Certificate: it compares the building to the BFE. New construction in a floodplain near Dinosaur National Monument often needs a floodplain permit; call the permitting office before you plan.

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.
