September 29, 2020 – Harris County Commissioners Court authorized the acquisition of a tract of land for this project.


This project (Project ID: P518-12-00-E001) will construct a dry-bottom, in-line stormwater detention basin and a wet-bottom, off-line stormwater detention basin to reduce the risk of flooding by holding excess stormwater during heavy rain events. When the project has been completed, the stormwater detention basins will hold approximately 229 additional acre-feet, or almost 75 million additional gallons, of stormwater storage in the Halls Bayou Watershed. All projects included within C-41 will make improvements to the main stem of Halls Bayou. 


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


The stormwater detention basins will be located along the northern bank of the main stem of Halls Bayou, just upstream of IH-45. Constituting 34 acres in area, the proposed project site is bounded by Blue Bell Road to the north, Halls Bayou to the south, Angie Lane to the west and IH-45 to the east. 


This project is in the FEASIBILITY STUDY stage.
