Short answer: TxDOT’s Houston District is widening FM 529 for about 12 miles, from SH 99 (Grand Parkway) west to FM 362, in Harris and Waller Counties. The right of way grows from about 120 feet to about 180 feet, requiring roughly 106 to 109 acres of new right of way. Acquisition began in summer 2025. If you own frontage on FM 529, expect an appraisal and a written offer, and review both before you sign.

Why FM 529 frontage is valuable

The FM 529 corridor west of the Grand Parkway is growing fast, with new subdivisions and commercial sites around Cypress and Katy. Land with highway frontage often has value well above its current farm or residential use. An appraisal that treats your tract as acreage, instead of as future commercial or subdivision land, may understate what you are owed.

How the TxDOT offer process works

  1. Appraisal of the strip and any damage to the remainder
  2. Initial offer in writing, with the Texas Landowner’s Bill of Rights
  3. Final offer at least 30 days later, with the appraisal reports relied on, and at least 14 days to respond
  4. Condemnation and a special commissioners’ hearing if there is no agreement

What to look for in an FM 529 offer

  • Highest and best use of the whole tract, not just its current use
  • Driveways, medians and turn lanes that change how customers reach you
  • Setbacks, parking and septic or detention that may no longer fit after the taking
  • Signs, gates, fences and trees in the strip
