Project Description

Recent Actions

May 2019  Construction began on Phase 1, the south cell, of this basin. 

July 30, 2019 – Harris County Commissioners Court authorized an agreement with an engineering firm for an additional $185,020 in engineering services in support of this project. 

June 18, 2019  A Community Engagement Meeting was held for this project 

March 26, 2019 – Harris County Commissioners Court awarded a $6.85 million contract for construction of Phase I (the south cell) of this project. 

January 29, 2019 – Harris County Commissioners Court approved a $49,976 agreement with an engineering firm for materials engineering and testing services in support of this project. 

December 18, 2018 – Harris County Commissioners Court authorized an $100,000 amendment to a previous $543,000 agreement with an engineering firm to provide final design of this project 

October 9, 2018 – Harris County Commissioners Court authorized negotiations with a consultant for materials engineering and testing services in support of this project 

December 19, 2017 – Harris County Commissioners Court approved a $543,000 agreement with an engineering firm for design, bidding and construction phase engineering services in connection with this project.

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 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.

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.
