Ahead of any purchase around Gladewater, pull up the Upshur County flood zone map: FEMA's zone label affects insurance, building rules and resale. This Upshur County guide covers: finding the address on FEMA's map, reading the zone codes, and matching it with the county parcel viewer.
Getting started with the Upshur County flood zone map
Flood zones come from FEMA's Flood Map Service Center: search an address around Coffeeville, and choose the dynamic map. Vacant ground around Kelsey is still easy to locate: zoom in from the nearest road then click the parcel area.
The viewer Upshur County publishes
Go first to the Texas county CAD map; it covers each tax parcel from Rhonesboro to Ore City. With a lot near Coffeeville, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a parcel near Diana, save the parcel ID from that panel; each records desk in the county will want it.
Reading A, AE and X
For property near Union Grove, A and V zones mark the Special Flood Hazard Area, land with a 1-percent chance of flooding in any year. For property near Gilmer, shaded Zone X is moderate risk, between the 1% and 0.2% annual chance floods; plain X, or C on older maps, means minimal mapped risk.
Limits of the parcel data
Closer to East Mountain, the acreage figure is an assessed number; only a licensed surveyor can set the real corners on the ground. In and around Union Grove, owner names and values update on a schedule, so a deed recorded last month can take weeks to appear.
The paper trail behind a parcel
On ground around Gilmer, the map is an index, not the title: deeds, plats and easements for parcels in the county are kept by the County Clerk. Long-held tracts near East Mountain can sit on many deeds, so a title company can sort it out if money is changing hands.
Low spots and local drainage
Small streams around Union Grove aren't always studied in detail, so look for water marks and debris lines. Marshy spots near Ore City can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
Which office to call
If the acreage or value on a parcel near Rhonesboro looks off go to the appraisal district, since that office keeps the assessment data. Questions about what you can build around Kelsey need the planning or permitting office, and the answer depends on jurisdiction.
A quick look at the area
Gilmer holds the county offices, home to the main records offices. You'll also find Clarksville City, East Mountain, Gladewater, and Ore City, each with its own cluster of lots. Around 43,281 people call Upshur County home (Census estimate, 2023) on roughly 583 square miles. Upshur County was formed in 1846, so old deeds can run back a long way.
When a parcel crosses a boundary
Upshur County meets Camp County, Gregg County, Harrison County, Marion County, and Morris County, all with their own assessor records. A tract near the line by Gilmer can show up across two assessors' files, so look at the neighboring map before you assume the acreage. With a lot near Diana, the Platbookmapper state page lists each bordering county map across Texas.
Matching the zone to the lot lines
FEMA doesn't draw property lines, so check the Texas county CAD map too to see exactly which lot near Clarksville City you're looking at.
A short flood checklist
For a home near Rhonesboro, ask the seller for any Elevation Certificate before closing; an insurance quote early keeps the budget honest.
Money questions tied to the zone
For a home near Coffeeville, get the Elevation Certificate if one exists: it can change the insurance price a lot. Building or adding on near Warren City in a mapped zone can trigger elevation rules; check with the county or town building office early.
Field tips
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Diana, so load it before you lose signal. A screenshot of the parcel near Diana with its ID is a good backup.
Upshur County: common questions
How do I check the flood zone for an address in Upshur County?
Short answer: FEMA's free map shows the zone for any spot near Kelsey, and the zone code appears on the map.
What is a LOMA for land near Kelsey?
If you're looking near Ore City, a Letter of Map Amendment (LOMA) from FEMA can remove a structure on naturally high ground; a surveyor's elevation data supports it.
Is flood insurance mandatory near Ore City?
It depends, but for a building near Enoch in an A or V zone with a federally backed or regulated mortgage, it's generally required, in communities that take part in the NFIP.
What is the difference between Zone A and AE near East Mountain?
In and around Clarksville City, both are high-risk zones, but only AE has a base flood elevation; unnumbered A zones don't list one.
Who do I call about a parcel near Clarksville City?
For a home near Enoch, the appraisal district handles values and the tax roll, and the County Clerk keeps deeds.
