PROJECT DESCRIPTION

Bond Project C-28 will construct channel conveyance improvements and construct a stormwater detention basin 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.

Bond Project C-28 will work in conjunction with two proposed Harris County Engineering Department proposed: neighborhood drainage improvements in the Aldine Village subdivision and neighborhood drainage improvements in the Oak Glen Place subdivision.

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

Location

Tributary P118-25-00 is located just upstream (west) of Hardy Toll Road with an approximate length of 0.7 miles and a drainage area of 100 acres. The modeled channel terminates at Aldine Mail Route Road but continues north as a simple roadside ditch. Tributary P118-25-01 intersects Tributary P118-25-00 about 1,200 feet south of Aldine Mail Route Road. The exact project location is yet to be determined.

Stage

This project is currently in the PRELIMINARY ENGINEERING stage. This stage is expected to be complete in late winter 2021/2022. This stage of the project will result in a preliminary engineering report with a recommended project that can be taken to Harris County Commissioners Court for approval and then advanced to the DESIGN stage. The preliminary engineering report may identify needed right-of-way acquisition, utility relocation and a preliminary cost estimate.

Bond Project Listing

Bond Project C-28 is a “Partnership” project. Total allocation for this project is currently $24 million on the Bond Project List, of which approximately $21.6 million is partnership funding and $2.4 million is local funding.

The Flood Control District applied for funding through the Texas Water Development Board’s (TWDB) Flood Infrastructure Fund in September 2020. In September 2021, the Flood Control District was awarded a nearly $3.9 million grant for this project from the TWDB.

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 $12.1 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.
