Galveston County, Texas
Galveston County stretches along Galveston Bay south of Houston, from the commuter hubs of League City and Friendswood to the island city of Galveston and industrial Texas City. Mainland growth runs down I-45; on the coastal side, surge zones, windstorm-insurance territory and seawall elevation rules separate buildable lots from speculation.
