The Houston-Galveston region is one of the most flood-impacted areas in the nation. Due to its vulnerability to tropical storm events, the metropolitan area is regularly subjected to billion-dollar losses when residential and industrial areas are inundation from storm surge. Based on expected sea-level rise, more intense rainfall episodes, and a rapidly growing population, the flood loss problem is becoming worse. In recent years, scientists, policy makers, and elected officials have been calling for a comprehensive coastal storm surge protection system for the Galveston Bay region, yet little is understood on the future costs of flooding in the Houston Galveston Region.
