Hurricane exposure, windstorm and flood insurance
Lago Mar is in Galveston County, where Hurricane Ike made landfall near Galveston on Sept. 13, 2008 as a Category 2 storm with a destructive surge along the upper Texas coast. Because the county is in TWIA's catastrophe area, each home needs a windstorm certificate of compliance (WPI-8) to qualify for TWIA wind and hail coverage, and TDI's windstorm code follows the 2024 IRC and IBC as of April 1, 2026. Flood risk differs by lot, so the lot itself has to be checked.
- Ask the builder or seller for the WPI-8 and look it up on TDI's site.
- Ask for the elevation certificate, and price flood insurance even outside a high-risk zone.
Before you make an offer: Before you offer, check the lot on FEMA's map and get quotes for homeowners, windstorm and flood coverage.
