Before you buy or build near Interstate 20, check the Midland County flood zone map: FEMA's zone label affects insurance, building rules and resale. What this Midland 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 Midland County flood zone map
Start with FEMA's Flood Map Service Center: type an address near Interstate 20, and pick the FIRMette or map view. Rural land near Interstate 20 with no street number can still be found: search the nearest road then click the parcel area.
Getting to the right map
Parcels around Interstate 20 can be looked up on the Midland CAD interactive map, free to use and open without a login. If you only know roughly where the land is, pan along Interstate 20 and select the outline. For a tract near Interstate 20, a pop-up or side panel normally shows the owner of record, assessed acreage, the parcel number and often a sale date.
Who handles what
For assessment questions about property around Interstate 20 are handled by the appraisal district, the office behind the parcel record. Building or septic questions for a lot near Interstate 20 are for the local planning and health departments, depending on whether the land is inside town limits.
Water near Interstate 20
Creeks and ditches near Greenwood aren't always studied in detail, so ask neighbors about past flooding. Wetlands near Interstate 20 can limit building even outside a flood zone; check the National Wetlands Inventory mapper for a first look.
Taking the map into the field
Most viewers work in a phone browser, handy when you're parked on a road near Interstate 20, though signal can drop in rural spots. A printout of the tract near Interstate 20 helps when you meet an owner or agent.
A word on accuracy
Tax maps are drawn for assessment, not measured on the ground, so a tree line near Interstate 20 may sit a few yards off the line on screen. Owner names and values update on a schedule, so a recent sale near Interstate 20 may not show yet.
A quick look at the area
Midland holds the county offices, home to the main records offices. You'll also find Odessa, Chub, Greenwood, and Interstate 20, where town lots give way to larger tracts. Around 177,108 people live in Midland County (Census Bureau estimate, 2023) on some 900 square miles. Midland County was formed in 1885, which matters when you trace an old farm's title.
When a parcel crosses a boundary
Midland County touches Andrews County, Ector County, Glasscock County, Martin County, and Reagan County, all with their own assessor records. Ground near Interstate 20 that runs to the line may be split across two assessors' files, so open the neighboring map before you assume the acreage. With a lot near Interstate 20, our state page lists each neighboring county map across Texas.
Sections, lots and bearings
Rural deeds near Interstate 20 commonly use metes-and-bounds descriptions, which trace the boundary call by call. Subdivision lots in Interstate 20 refer to a recorded plat, which is simpler to follow. Write down the legal description for the tract near Interstate 20 when you talk to a surveyor.
What the zone letters mean
If you're looking near Interstate 20, zones beginning with A or V mark the Special Flood Hazard Area, meaning a 1% or greater chance of flooding each year. For acreage around Interstate 20, a low-risk label isn't a guarantee: FEMA notes that floods happen outside mapped zones too.
What to request from a seller
Request for any Elevation Certificate for the house near Interstate 20; getting a quote early keeps the budget honest.
Lining it up with the parcel map
If only part of a parcel near Interstate 20 is shaded, what matters is where the building sits.
Lenders and permits
For a structure inside an A or V zone and the loan is federally backed or regulated, the lender will require flood insurance in communities in the NFIP, whether the land is near Interstate 20 or elsewhere in the county. New construction in a floodplain near Interstate 20 usually means extra permit review; ask the local floodplain administrator early.

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.
