Flood Control District Completes First Phase of Aldine Westfield Stormwater Detention Basin

The Harris County Flood Control District has completed construction of Phase 1 of the Aldine Westfield Stormwater Detention Basin, located south of Greens Road and north of Beltway 8, just off Aldine Westfield Road in the Greens Bayou Watershed. The $6.94 million construction contract was funded through the Flood Control District’s Capital Improvements Program and the 2018 Bond Program.

The Aldine Westfield Stormwater Detention Basin is expected to reduce flood risks in the Greens Bayou watershed by taking in excess stormwater during heavy rain events and then releasing it slowly back into the channel once the threat of flooding has passed. Phase 1 provides storage for approximately 667 acre-feet, or just over 217 million gallons of stormwater that might otherwise flood homes and businesses during heavy rain events.

“The completion of Phase 1 of this project brings us closer to providing flood protection to some of the most flood-prone neighborhoods in our County,” said Harris County Precinct One Commissioner Rodney Ellis, whose precinct includes the Aldine Westfield detention basin in north-central Harris County. “The Greens Bayou Watershed has been long overdue for this type of investment, and I am glad that our County’s equity guidelines have allowed us to prioritize the people and neighborhoods that most need flood protection.”

The Aldine Westfield Stormwater Detention Basin project is designed to be constructed in two phases. Phase 1 was constructed in the southern compartment of the stormwater detention basin footprint. Phase 2, currently undergoing design, will be constructed in the northern compartment of the site and is expected to hold another 600 acre-feet (190 million gallons) of stormwater once complete.

The project is part of the overall flood risk reduction plan for the mid-reach stretch of Greens Bayou. This plan includes 11 miles of channel conveyance improvements and the construction of four stormwater detention basins: Aldine Westfield (Phase 1 complete), Glen Forest (complete), Kuykendahl (complete) and Lauder (Phase 1 under construction).
