Weighing a property around Anton? A quick look at the Washington County flood zone map shows whether the lot falls inside a mapped floodplain, and the lookup is free. This Washington County guide covers: finding the address on FEMA's map, reading the zone codes, and pairing it with the Colorado Public Parcel Map.
Getting started with the Washington County flood zone map
For land near Akron, start with FEMA's Flood Map Service Center: enter the street address, and pick the FIRMette or map view. Rural land near Platner with no street number is still easy to locate: search the nearest road and click inside the land.
Getting to the right map
Parcels around Lindon appear on the Colorado Public Parcel Map, which opens without registering. For a home near Anton, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. If the land is near Akron, save the parcel ID from that panel; every records desk in the county will want it.
Decoding the flood zone labels
If you're looking near Otis, any A or V zone are Special Flood Hazard Areas, which FEMA defines as a 1% annual chance of flooding. For property near Cope, minimal risk is not no risk: according to FEMA, many claims come from moderate- and low-risk areas.
Before you lean on the lines
If the land is near Lindon, the acreage figure is an assessed number; just a licensed surveyor sets the real lines on the ground. In and around Akron, owner names and values update on a schedule, so a deed recorded last month can take weeks to appear.
What to request from a seller
Request for any Elevation Certificate for the house near Akron; getting a quote early avoids surprises.
When a parcel crosses a boundary
Washington County borders Adams County, Arapahoe County, Kit Carson County, Lincoln County, and Logan County, all with their own assessor records. A tract near the line by Akron can be split across two assessors' files, so look at the neighboring map too. With a lot near Otis, our state page links each neighboring county map for Colorado.
Field tips
Most viewers work in a phone browser, which helps when you're standing on land near Cope, so load it before you lose signal. A screenshot of the parcel near Anton with its ID helps when you meet an owner or agent.
Sections, lots and bearings
Colorado follows the Public Land Survey System, which means a tract near Lindon is described by section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though real sections near Last Chance vary in size. Copy the legal description from the record for the parcel near Platner before you request a deed or survey.
The paper trail behind a parcel
For a parcel near Platner, the map is an index, not the title: recorded deeds, subdivision plats and easements for parcels in the county sit with the County Clerk and Recorder. For acreage around Last Chance, bring the book and page shown in the record panel and the lookup takes minutes.
Lining it up with the parcel map
FEMA's map shows zones but not ownership, so check the Colorado Public Parcel Map too to see exactly which lot near Cope you're looking at.
Getting your bearings
Akron holds the county offices, where most land records are kept. You'll also find Otis, Cope, Anton, and Last Chance, each with its own cluster of lots. About 4,855 people live in Washington County (Census estimate, 2023) on some 2,518 square miles. Washington County dates to 1887, which matters when you trace an old farm's title.
Offices that can help
For assessment questions about property around Otis go to the County Assessor, since that office keeps the assessment data. Questions about what you can build around Cope are for the local planning and health departments, and the answer depends on jurisdiction.
Low spots and local drainage
Low-lying fields near Platner aren't always studied in detail, so ask neighbors about past flooding. Wetlands near Akron can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
Insurance, lenders and building
If you're looking near Platner, ask for an Elevation Certificate: it can change the insurance price a lot. Remodeling a house in a zone near Otis usually means extra permit review; 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.
