Request by the Flood Control District for approval to submit an application to the Texas Water Development Board for grant funds in the amount of $2,500,000, with no required match, for Halls Aldine Westfield South Stormwater Detention Basin and Mainstem Channel Conveyance Improvements (Halls Bayou Watershed, Bond ID C-41, Precinct 2).

Background and Discussion:
It is recommended that the Flood Control District be authorized to apply for grant award funds from the Texas Water Development Board to fund the Halls Aldine Westfield South Stormwater Detention Basin & Mainstem Channel Conveyance Improvements in the Halls Bayou Watershed. The 89th Texas Legislature allocated funds in Senate Bill 1 to the Harris County Flood Control District. Senate Bill 1 was signed by the Governor on June 22, 2025, and was effective on September 1, 2025. This allocation from the Texas Legislature is being obtained through the Texas Water Development Board. The project in Senate Bill 1 is the Halls Aldine Westfield South Stormwater Detention Basin & Mainstem Channel Conveyance Improvements in the Halls Bayou Watershed (HC Pct. 2). These grant funds were appropriated in Senate Bill 1 from the 89th Texas Legislature, secured by Representative Walle, HD140.
Expected Impact:
This grant would fund feasibility, preliminary engineering and design. The feasibility, preliminary engineering report, and design will determine the ultimate benefits provided. The proposed P118-00-00 Halls Aldine Westfield South Stormwater Detention Basin & Mainstem Channel Conveyance includes approximately 950 acre-feet of storage within a proposed 90-acre site between Mesquite Street and Halls Bayou. The channel improvements are approximately 5,500 linear feet along Halls Bayou. Due to the size of the basin area, a phased implementation plan will likely be proposed. It is estimated that following the ultimate project, the 100-yr (preAtlas-14) inundation area would be removed from approximately 339 structures, approximately 6 miles of roadway, and approximately 221 acres. The Flood Control District will utilize its resources and applicable consultants during the design and construction phases of the project, as well as the management of the grant approval process in compliance with Harris County statutes, applicable laws of the state of Texas, and Policy regarding Federal Grant Awards.
Alternative Options:
The alternative is to not apply for grant funding, wherein existing flooding risks remain in place, or the project will need to be entirely funded with local funding.
County Strategic Plan Goal: 2. Connect our community with safe, reliable, equitably distributed, and well-maintained infrastructure.
County Strategic Plan Objective: H: Improve the condition and resilience of County transportation, flood control, and other infrastructure.
