Recent Action: December 4, 2018 – Harris County Commissioners Court approved a $188,180 agreement with an engineering firm for final design of this project.

C-05 South Belt Stormwater Detention Basin


This bond project includes Phase 3 design and construction to expand the South Belt Stormwater Detention Basin (HCFCD Unit A520-03-00). 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. The basin provides stormwater storage needed for mitigation of expected increases in stormwater flows resulting from future channel improvements to Beamer Ditch (HCFCD Unit A120-00-00, also known as Mud Gully), Turkey Creek (HCFCD Unit 119-00-00) and other projects.The basin is ultimately designed to hold up to 1,550 acre-feet or 505 million gallons of stormwater.

This project is located on a 174-acre site on Beamer Ditch/Mud Gully, near the intersection of Beamer and Dixie Farm roads in the Clear Creek watershed of southeast Harris County.


Phase 3 of the basin excavation is currently in the DESIGN stage. This stage will result in engineering plans and documents necessary for the next bidding and construction stage.

Bond Project C-05 is a potential Partnership project. Total allocation for Phase 3 of the basin is currently $15.95 million on the Bond Project List, of which approximately $11.96 million would be partnership funding, if granted, and $3.99 million would be local costs. If partnership funds are not available, the project will be funded totally from the 2018 Bond Program as a “Local Only” project.

 Phase 2

  • This phase expanded the basin to include basin compartments south and west of the Phase 1 compartment.
  • Construction began in November 2016 and was substantially complete in 2019.
  • Harris County Commissioners Court awarded a $15.78 million construction contract to James Construction Group LLC for Phase 2 of the basin project.
  • The project continued the partnership between Harris County Flood Control District and Galveston County.

Phase 1

  • This phase included excavation of the basin compartment northeast of Beamer Ditch/Mud Gully.
  • Construction began in late September 2014 and was complete in 2018.
  • Harris County Commissioners Court awarded an approximately $3.46 million construction contract to low bidder Trans-Global Solutions Inc.
  • The project was a partnership between the Harris County Flood Control District and Galveston County. Galveston County pledged up to $10 million of total basin construction costs.
  • Construction costs for Phase 1 were shared equally by the Flood Control District and Galveston County.
