Vulnerability Assessment for Hood County, TX

Abstract

Looking forward, we mapped the 100-year and 500-year floodplains in the County. A 100-year floodplain indicates areas that have a 1% chance each year of flooding. The majority of the floodplain follows the Brazos River, as would be expected, and its small tributaries and creeks. This floodplain does flow through the historic area of downtown Granbury and along the Lake. We also mapped potential sources of technological disaster or spills including known Superfund sites (areas the EPA has identified in need of hazardous waste clean-up) and areas that host tanks or can have spills of toxic substances. There are two Superfund sites, one in downtown Granbury along the River and one to the north-east of town.
