Before you buy or build near Attwater Prairie Chicken National Wildlife Refuge, look at the Colorado County flood zone map: a mapped flood zone changes insurance, building rules and resale. What this Colorado County guide covers: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the Colorado CAD interactive map.
Where the Colorado County flood zone map lives
Start with FEMA's Flood Map Service Center: search an address around Garwood, and choose the dynamic map. Vacant ground around Rock Island is still easy to locate: search the nearest road and click inside the land.
Pulling up a parcel
Go first to the Colorado CAD interactive map; it maps every tax parcel from Rock Island to Nada. If you only know roughly where the land is, follow the nearest road on the aerial and select the outline, whether the land is near Eagle Lake or elsewhere in the county. For a home near Attwater Prairie Chicken National Wildlife Refuge, copy the parcel ID before closing the panel; each clerk in the county asks for it first.
Water near Glidden
Low-lying fields near Rock Island aren't always studied in detail, so walk the land after rain. Marshy spots near Attwater Prairie Chicken National Wildlife Refuge can limit building too; check the National Wetlands Inventory mapper for a first look.
What to request from a seller
Request for any Elevation Certificate for the house near Rock Island; an insurance quote early avoids surprises.
Places you'll see on the map
Columbus is the county seat, which is where the courthouse records live. You'll also find Eagle Lake, Weimar, Garwood, and Glidden, each with its own cluster of lots. About 21,117 people call Colorado County home (Census estimate, 2023) spread over some 960 square miles. Colorado County was organized in 1837, so old deeds can run back a long way. Places such as Attwater Prairie Chicken National Wildlife Refuge make handy reference points on the map.
Next door to Colorado County
Colorado County borders Austin County, Fayette County, Jackson County, Lavaca County, and Wharton County; every one of them runs a separate parcel map. A tract near the line by Eagle Lake may be split across two assessors' files, so look at the adjacent map too. Out toward Sheridan, our state page links each neighboring county map across Texas.
Sections, lots and bearings
Tracts outside towns near Attwater Prairie Chicken National Wildlife Refuge are often described by metes and bounds, listing bearings, distances and landmarks. Subdivision lots in Attwater Prairie Chicken National Wildlife Refuge usually use lot and block from a recorded plat instead, which is simpler to follow. Copy the legal description from the record for the parcel near Sheridan before you request a deed or survey.
Decoding the flood zone labels
An AE label comes with a base flood elevation, and an unnumbered A zone has none; builders around Eagle Lake design to it. For a tract near Attwater Prairie Chicken National Wildlife Refuge, a shaded X area marks moderate flood hazard, between the 1% and 0.2% annual chance floods; unshaded X is minimal risk.
Backing up the map with records
Before you sign anything, get the recorded deed from the County Clerk; the parcel map near Rock Island only summarizes it. Older tracts near Attwater Prairie Chicken National Wildlife Refuge can sit on several deeds, and a title company is worth hiring if money is changing hands.
Matching the zone to the lot lines
FEMA doesn't draw property lines, so open the Colorado CAD interactive map next to see exactly which lot near Nada you're looking at.
Using it on a phone
Most viewers work in a phone browser, which helps when you're standing on land near Attwater Prairie Chicken National Wildlife Refuge, so load it before you lose signal. A screenshot of the parcel near Weimar with its ID is a good backup.
Insurance, lenders and building
If you're looking near Rock Island, ask for an Elevation Certificate: it records the building's elevation against the base flood. Building or adding on near Eagle Lake in a mapped zone can trigger elevation rules; check with the county or town building office early.
Getting answers from the right desk
Anything recorded against property around Rock Island are with the County Clerk, sometimes only in person. Zoning, permits and septic questions near Columbus need the planning or permitting office, depending on whether the land is inside town limits.
