History Of The District

HISTORY HIGHLIGHTS

Shortly after the Allen brothers chose to establish Houston at the confluence of Buffalo and White Oak Bayous, virtually every structure in the new settlement flooded. The Flood District was created in response to repeated flooding problems and has evolved over time.Since its creation, the Flood Control District's role has become increasingly complex, and the District’s responsibilities now include many other facets that contribute to regional flood risk reduction.
