High-risk regions of Texas — and what's stored there.

Houston / Galveston

Harvey-class rainfall events plus Gulf surge. Heavy concentration of restored muscle cars, late-model exotics and Houston-area private collections.

Bolivar Peninsula / Beaumont

Ike storm-surge corridor. Coastal collections and inherited family vehicles stored in slab-on-grade garages.

Corpus Christi / Coastal Bend

Direct hurricane landfall zone (Harvey, Hanna). Heavy classic American truck and muscle ownership.

Austin / Hill Country

Flash Flood Alley — the most dangerous flash-flood corridor in North America. Six-hour warning windows on Onion Creek, the Blanco and the Guadalupe.

Dallas–Fort Worth

Trinity River flooding plus urban drainage failure in Highland Park and University Park collections.

San Antonio

Olmos Basin flash flooding. Concentration of restored vehicles in older neighborhoods with century-old storm infrastructure.

Pre-Event Protocol

The Texas pre-storm checklist.

Whether the threat is named, or it's just the radar lighting up over the Hill Country.

  1. T-48 hr
    Confirm garage drainage is clear. Move floor-stored items. Pre-position FloodVault at the front of the vehicle.
  2. T-24 hr
    Open and inspect. Verify the TIZIP track is clean. Confirm your deployment path.
  3. T-6 hr
    Deploy. 8–12 minutes solo. Close the zipper. Verify continuous seal along the base.
  4. T-0
    Evacuate inland — or just go to bed. The vehicle is sealed.

Harvey was a 1-in-1,000-year storm. So was the next one.
