This project includes right-of-way acquisition, design and construction of a stormwater detention basin, HCFCD Unit U501-06-00, on South Mayde Creek. Stormwater detention basins reduce flooding risks and damages during heavy rain events by safely storing excess stormwater and slowly releasing it back to the bayou when the threat of flooding has passed.


This project will be located near South Mayde Creek in the Addicks Reservoir watershed of northwest Harris County.


This project is currently in the PRELIMINARY ENGINEERING stage. This stage of the project will result in a recommended project that can be taken to Harris County Commissioners Court for approval and then advanced to the DESIGN stage.
