Alvin Texas sits in Brazoria County south of Houston and experienced catastrophic flooding during Hurricane Harvey in 2017 — Alvin recorded some of the highest rainfall totals in the event at over 40 inches. The city sits near the Houston Ship Channel petrochemical complex and Dow Chemical's Lake Jackson operations. Brazoria County's low elevation and Gulf Coast position create recurring hurricane flood risk. NASA Johnson Space Center is to the northeast creating aerospace infrastructure in the surrounding region.
