Project Description

Bond Project C-33 will construct a two-phase stormwater detention basin to reduce the risk of flooding in the mid-reach stretch of Greens Bayou by taking in excess stormwater during heavy rain events and then releasing it slowly back to the channel when the threat of flooding has passed. Phase 1 was constructed to hold approximately 667 acre-feet of stormwater (approximately 217 million gallons), and Phase II is expected to hold another 600 acre-feet (190 million gallons) of stormwater once complete. Together, the two phases are anticipated to hold 1,250 acre-feet, or 407.3 million gallons, of excess stormwater that might otherwise flood homes and businesses.

South and north compartments are being constructed in two phases – the south compartment first – to allow for necessary environmental permitting. Eventually, the two basin compartments will be connected by two 5'x4' reinforced concrete boxes and will outfall into Greens Bayou. Prior to construction of Phase I (completed in March 2021), portions of the stormwater detention basin partially excavated via an earlier excavation and removal agreement.

Greens Bayou Mid-Reach Program
This project is part of the Greens Mid-Reach Program. As originally envisioned, the Greens Mid-Reach Program is a several-hundred-million-dollar effort focused on the area from Veterans Memorial Drive downstream to JFK Boulevard. The Flood Control District began implementing this vision in the 2000s to bring much-needed flood risk reduction to residents along Greens Bayou.

In total, the Greens Mid-Reach Program proposes 11 miles of channel conveyance improvements and 10,500 acre-feet of stormwater storage through five stormwater detention basins to mitigate the increased flow of water and prevent any regional impacts. As of July 2022, 8,200 acre-feet of the required stormwater detention has already been completed or is currently under construction, including Bond Project C-33, the Aldine Westfield Stormwater Detention Basin, and Bond Project C-34, the Lauder Stormwater Detention Basin. The Glen Forest Stormwater Detention Basin and the Kuykendahl Stormwater Detention Basin are fully constructed and the fifth Hardy Stormwater Detention Basin is still in early feasibility.

Location

This project is located south of Greens Road and north of Beltway 8, just off of Aldine Westfield Road.

Stage

Phase I of this project is COMPLETE. Phase II of this project is in the DESIGN stage.

Bond Project Listing

Total allocation for all future stages and phases of Bond Project C-33 on the Bond Project List is currently $15.1 million. Both phases have received funding through the Flood Control District's Capital Improvements Program and through the 2018 Bond Program. Phase I is fully funded. Total estimated cost for Phase II is $10.9 million and to fund the project to completion, a grant application for Community Development Block Grant Mitigation (CDBG-MIT) funding was applied for and submitted to The Texas General Land Office in October of 2020 in the amount of about $10 million.
