Project Description

The Aldine Westfield Stormwater Detention Basin (HCFCD Unit P500-04-00) will reduce flood risks in the Greens Bayou watershed by taking in excess stormwater during heavy rain events and then releasing it slowly back to the bayou when the threat of flooding has passed. The basin will be located south of Greens Road and north of Beltway 8, just off of Aldine Westfield Road.

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.

Stage

This project is currently in 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.

Bond Listing

List of 2018 Bond Projects

The Harris County Flood Control District has a significant number of flood damage reduction projects occurring all over Harris County as part of its on-going Capital Improvement Program (CIP), Operations and Maintenance, and the 2018 Bond Program.

The map will be updated when projects advance or when more information becomes available.

Project Lifecycle

Every flood damage reduction project is unique. Yet each project begins and ends, with common and predictable milestones along the way. Whether a project moves forward – and how quickly – depends on many factors, including the availability of funding at each milestone, shifting community priorities for flood damage reduction, and other changing circumstances (such as the price of trees or concrete) from year to year.
