If the PDF panel for Tyler County is hard to read, FEMA's National Flood Hazard Layer viewer draws the zones over aerial imagery and reports the zone wherever you click near Chester. Then open the Texas county CAD map for Tyler County to confirm the parcel near Chester. The Tyler County record gives the parcel number and legal description that an insurer or lender near Chester may ask for.

Zone A, AE and X in plain English
On the FIRM covering Tyler County, zones that start with A or V are Special Flood Hazard Areas, defined by a 1-percent annual chance of being flooded. Zone AE near Woodville means FEMA published a base flood elevation; plain Zone A means no detailed elevation was studied. Shaded Zone X around Chester sits in the moderate band between the 100-year and 500-year floods. Clear, unshaded X near Chester is outside the 500-year floodplain.

A creek near Woodville that lists no detailed zone can still flood; FEMA says moderate- and low-risk areas still carry risk.
Questions to ask before buying in Tyler County
For a house near Woodville, ask the seller for any elevation certificate on file and the current flood insurance declarations page. Quotes for land near Hillister depend on the zone and the building's elevation, so bring both to the agent.
Flood insurance and building rules in Tyler County
Here's why the zone matters at a closing in Chester. When a county home falls inside an A or V zone and carries a federally backed mortgage, federal rules call for flood insurance; that applies where the local government around Woodville is in the National Flood Insurance Program. Outside the A zones around Woodville, coverage is optional, although some lenders require it anyway. Where a structure near Chester looks higher than the shading suggests, the owner can ask FEMA for a Letter of Map Amendment (LOMA), supported by elevation data from a professional surveyor. Building or filling inside a mapped zone near Chester commonly requires a permit and an elevation check; the county floodplain administrator can say what applies.
Tyler County, TX: common questions
Who prepares an elevation certificate for a house in Colmesneil?
A professional surveyor or engineer prepares it, and the building office serving Colmesneil may already have one on file for newer construction.
Does the Tyler County parcel map show flood zones?
Check the layer list in the Texas county CAD map; if Tyler County includes a floodplain layer, confirm the zone on FEMA's map anyway.
Does a 100-year floodplain near Ivanhoe flood only once a century?
Not at all; a Tyler County tract in that zone carries a 1-in-100 chance in any single year, not a once-a-century schedule.
How do I know if a property in Tyler County is in a flood zone?
Look it up at FEMA's Flood Map Service Center, then match the parcel lines in the Texas county CAD map; for land near Ivanhoe, a zone starting with A or V is high risk.
Do I need a permit to build in the floodplain near Colmesneil?
Building in a Special Flood Hazard Area near Colmesneil usually needs a floodplain permit and may require elevating the structure, so check with the county floodplain administrator.
Can a flood zone in Tyler County be changed?
For a lot in Colmesneil, hire a surveyor for an elevation certificate, then file a LOMA request with FEMA.
