Recent Action: Construction began in late May 2019 on Phase 1, the south cell, of this basin. 

C-33 Aldine Westfield Stormwater Detention Basin

Project Description

This project will construct a stormwater detention basin on a 113-acre site on Greens Bayou near the Sam Houston Tollway and Aldine Westfield Road in north central Harris County.

According to a conceptual engineering report completed in 2017 – and in keeping with its location just south of Bush Intercontinental Airport – the basin will be designed without a permanent pool so as not to attract waterfowl. South and north compartments will be constructed in two phases – the south compartment first – to allow for necessary environmental permitting. Eventually, the two basin compartments will be connected by a 48-inch pipe and will outfall into Greens Bayou. Portions of the basin -- formally identified as HCFCD Unit P500-04-00 -- have been partially excavated via an earlier excavation and removal agreement.

A preliminary goal is to design the basin to hold approximately 1,250 acre-feet, or more than 407.3 million gallons, of stormwater that otherwise might flood homes and businesses during heavy rain events.  The benefits of this project are best understood as part of a suite of projects – Progress Greens – that will work together to reduce flooding risks within the 213 square miles of the Greens Bayou watershed.

Project Stage

This project is currently in the DESIGN stage. This stage of the project will result in construction plans that can be taken to Harris County Commissioners Court for approval to seek construction bids and then advanced to the CONSTRUCTION stage.

Bond Project Listing

The Aldine Westfield Stormwater Detention Basin project is and will be funded both through the Flood Control District's Capital Improvements Program (for design of multiple phases) and through the 2018 Bond Program (for all future construction). Total allocation for all future stages and phases of Bond Project C-33 on the Bond Project List is currently $15.1 million. No funding partner has been identified at this time. If partnership funds are not available, the project will be funded totally from the 2018 Bond Program as a “Local Only” project.

Progress Greens...

....is the name given to a suite of flood damage reduction projects currently active in the Greens Bayou watershed of Harris County. The Harris County Flood Control District is taking the lead in some of those projects, with grant assistance from the Federal Emergency Management Agency (FEMA). In others, the U.S. Army Corps of Engineers will design and construct the project, with partnership assistance from the Flood Control District.

All projects under the Progress Greens umbrella will function together to reduce flooding risks and damages for residents and businesses within the 213 square miles of the Greens Bayou watershed.
