Project Description

Bond Project C-26 will construct channel conveyance improvements and construct stormwater detention basins to reduce the risk of flooding 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.

As part of the preliminary engineering stage, the Flood Control District is evaluating various alternatives, including channel conveyance improvements and stormwater detention basins, to determine the optimal solution for reducing the risk of flooding in this area.

This project is part the Watershed-Wide Project Implementation Program for Halls Bayou.


Tributary P118-23-00 is located just upstream (west) of Hardy Toll Road with an approximate length of 1.5 miles and drainage area of 780 acres. The channel terminates at Canino Road. Sub-tributaryP118-23-02 intersects with P118-23-00 near Gulf Bank Road.


This project is in the PRELIMINARY ENGINEERING stage and is expected to be compete in spring 2022. This stage of the project will result in a Preliminary Engineering Report (PER) with a recommended project that can be taken to Harris County Commissioners Court for approval and then advanced to the DESIGN stage. The PER may identify needed right-of-way acquisition, utility relocation and a preliminary cost estimate.

Bond Project Listing

Bond Project C-26 is a potential future Partnership project with the City of Houston and Harris County. Total allocation for this project is currently $28 million on the Bond Project List, of which approximately $25.2 million is partnership funding and $2.8 million is local funding.

Additionally, the Flood Control District has been aggressively pursuing multiple grant opportunities, including a grant application to the Texas General Land Office (GLO) for Community Development Block Grant for Mitigation (CDBG-MIT) funding in October 2020 in the amount of about approximately $28.5 million for this project. While that specific application was not awarded, as of December 2021, Harris County is continuing to work with the GLO on a potential $750 million commitment of CDBG-MIT funding for flood risk reduction projects across Harris County.

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.

Public Information Session

A series of projects in the Halls Bayou watershed are included in two separate applications for federal funding through the Community Development Block Grant for Mitigation (CDBG-MIT) Program. The projects included are Bond Project IDs: C-01, C-23, C-24, C-26, C-28, C-30 and C-41. A virtual Public Information Session to discuss these projects was held on:

Date: Wednesday, September 23, 2020
Time: 6:30 p.m. to 7:30 p.m.

The official public comment period for the CDBG-MIT applications will be open from October 3 – October 16, 2020. We encourage residents to learn more about the application process, submit a comment and view the meeting presentation and video:

Community Engagement Meeting

A Community Engagement Meeting for this project was held on November 11, 2019 at the Hardy Senior Center, 11901 W. Hardy Road in Houston.
