Halls Bayou (sub-watershed)

Halls Bayou, a tributary of Greens Bayou, is located in north central Harris County, Texas. Approximately 20 miles in length, Halls Bayou collects stormwater from the Veterans Memorial Drive area flowing east until it joins Greens Bayou at the city of Houston’s Brock Park. Flooding along Halls Bayou is a persistent hazard for area residents, businesses and property owners. Flooding has been documented at least 14 times since 1970. During Tropical Storm Allison in 2001, more than 13,000 homes in the Halls Bayou watershed flooded, and during Hurricane Ike in 2008 approximately 1,400 homes were damaged by flooding.

The actual timing of individual projects will depend on a variety of factors including environmental permitting and right-of-way acquisition. Projects will be authorized individually for funding by Harris County Commissioners Court, based on recommendations by the Flood Control District.
