Before you buy or build near Guthrie, pull up the King County flood zone map: a mapped flood zone changes insurance, permits and resale. In this King County guide: locating a parcel on FEMA's map, reading the zone codes, and confirming the outline on the county map.
Checking the King County flood zone map step by step
If you'd rather pan and zoom, open the National Flood Hazard Layer viewer, which draws the zones over aerial imagery, whether the land is near Guthrie or elsewhere in the county. Rural land near Grassland with no street number is still easy to locate: search the nearest road and click inside the land.
Opening the official parcel viewer
Your first stop is the King County parcel viewer; it maps every assessed parcel around Grow and Grassland. For a tract near Dumont, enter a street address, an owner's name or a parcel number, and the matching parcel lights up. For a parcel near Dumont, write down the parcel ID before closing the panel; each office in the county uses it to find the file.
Water near Grow
Small streams around Grow aren't always studied in detail, so walk the land after rain. Marshy spots near Guthrie can limit building too; check the National Wetlands Inventory mapper for a first look.
What the zone letters mean
Out toward Guthrie, A and V zones are Special Flood Hazard Areas, meaning a 1% or greater chance of flooding each year. If you're looking near Guthrie, shaded Zone X is moderate risk, between the 1% and 0.2% annual chance floods; unshaded X is minimal risk.
Backing up the map with records
For property near Finney, the map is an index, not the title: deeds, subdivision plats and easements for parcels in the county are filed with the County Clerk. Long-held tracts around Grow can trace back through several deeds, so a title company earns its fee before a purchase.
Matching the zone to the lot lines
FEMA doesn't draw property lines, so pair it with the King County parcel viewer to confirm you have the right parcel near Grow.
Sections, lots and bearings
Tracts outside towns near Guthrie commonly use metes-and-bounds descriptions, listing bearings, distances and landmarks. Subdivision lots in Guthrie usually use lot and block from a recorded plat instead, making them easier to find. Keep the legal description for land near Grassland for any title or survey request.
What the map can't tell you
If you're looking near Dumont, the acreage figure is a tax-roll number; only a licensed surveyor establishes the real boundary on the ground. In and around Grassland, owner names and values update on a schedule, so a deed recorded last month might lag behind.
What to request from a seller
With a lot near Finney, request for any Elevation Certificate before closing; getting a quote early avoids surprises.
On site with the map
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Grassland, so load it before you lose signal. A saved image of the lot near Grow and its lines is a good backup.
Getting your bearings
Guthrie is the county seat, home to the main records offices. You'll also find Dumont, Finney, Grow, and Grassland, each with its own cluster of lots. Roughly 217 people call King County home (Census Bureau estimate, 2023) spread over some 911 square miles. King County was organized in 1891, which matters when you trace an old farm's title. Places such as Grassland make handy reference points on the map.
Neighboring parcel maps
King County borders Cottle County, Dickens County, Foard County, Haskell County, and Kent County, and each of those keeps its own parcel map. Ground near Dumont that runs to the line can be split in two county records, so look at the neighboring map too. If the land is near Dumont, the Platbookmapper state page links every bordering county map across Texas.
Getting answers from the right desk
Questions about value or the owner field for land near Grow go to the appraisal district, since that office keeps the assessment data. Questions about what you can build around Grow need the planning or permitting office, depending on whether the land is inside town limits.
Money questions tied to the zone
If you're looking near Finney, an Elevation Certificate from a surveyor helps: it can change the insurance price a lot. New construction in a floodplain near Grow often needs a floodplain permit; check with the county or town building office early.

What is the difference between Zone A and AE for land near Grow?
For land near Grow, an AE zone has a 1% annual chance of flooding and a base flood elevation; unnumbered A zones don't list one.

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.
