PROJECT DESCRIPTION

The Clear Creek Federal Flood Damage Reduction Project is a partnership project between the U.S. Army Corps of Engineers, the Harris County Flood Control District, Galveston County, and Brazoria Drainage District No. 4. As of the June 2019 Project Partnership Agreement between the Corps and the Flood Control District, the Flood Control District is the lead agency for this project, under a non-federal implementation pilot program authorized by Section 1043(b) of the Water Resources Reform and Development Act (WRRDA) of 2014. 

As with other Corps projects led by the Flood Control District under Section 211(f) of WRDA 1996, this pilot program allows local sponsors to carry out federal projects subject to certain federal requirements, with the Corps providing administration and oversight. The pilot program also allows the Corps to transfer the estimated federal share of eligible project costs to the local sponsor before costs are incurred. 

As the lead agency, the Flood Control District will manage, design, and build the project; buy land, easements, and rights-of-way; relocate utilities; adjust or replace bridges; and operate and maintain portions of the project within Harris County after construction is complete. The Flood Control District will enter separate interlocal agreements to share the non-federal costs and the operation and maintenance responsibilities of the project. 

The project was identified and recommended by a General Reevaluation Report (GRR) completed by the Corps in 2013. The GRR presents an alternative to the Clear Creek Federal Project that was previously being implemented by the Corps, Flood Control District, and Galveston County based on a 1986 agreement. The revised project that will be constructed includes:

  • 2nd Outlet Channel and Gates from Clear Creek to Galveston Bay (already complete)
  • 15.1 miles of channel conveyance improvements along Clear Creek from State Highway 288 to Dixie Farm Road
  • 2.4 miles of channel conveyance improvements along Turkey Creek from Dixie Farm Road to Clear Creek
  • 2.1 miles of channel conveyance improvements along Mary's Creek from Harkey Road to State Highway 35
  • 0.8 miles of channel conveyance improvements along Mud Gully from Sagerock Drive to Beamer Road
  • 500 acre-feet of in-line stormwater detention along Clear Creek.
  • 22 bridge replacements or modifications
  • Environmental mitigation and enhancements

The Mud Gully (Beamer Ditch) project will be funded and constructed as part of the federal project and will extend existing concrete channel lining approximately 4,200 feet (0.8 mile) downstream along Beamer Ditch, from Sagerock Drive to Beamer Road, near the South Belt Stormwater Detention Basin.

Project Status

The Mud Gully portion of the federal project is in final design and is expected to go out for public bid in Spring 2020.

The remainder of the federal project is in preliminary engineering, with construction expected to begin in 2021.

Project cost and Funding

Current total cost for the Clear Creek project is estimated at $295 million. The estimated cost share is $147.5 million federal (50%) and $147.5 million local (50%). 

The project is one of four partnership projects between the Flood Control District and the Corps that were funded to completion by the Bipartisan Budget Act of 2018. The Corps has allocated a maximum amount of $187 million in federal funds to complete the project. 

History

The original 1986 Clear Creek Federal project called for more than 14 miles of channel conveyance improvements from Clear Lake to the Brazoria County line near Dixie Farm Road. Eleven bridge replacements or modifications were planned, and eight have been completed. 

A mile-long Second Outlet Channel from Clear Lake to Galveston Bay was also part of the plan, and its construction was completed in 1997 and was turned over to the Flood Control District to operate and maintain in 1998. The Second Outlet includes a large gated control structure that is opened during certain flooding conditions to allow flood waters to drain from Clear Lake to Galveston Bay, which in turn allows Clear Creek to drain sooner. During non-flooding conditions or "normal" conditions, the gates are closed to maintain a pre-project salinity level and environmental conditions in Clear Lake.

In June 1999, in response to community opposition, the Corps initiated a General Reevaluation Study to evaluate various alternatives. Brazoria Drainage District No. 4 joined the Flood Control District and Galveston County as local sponsors for the Corps reevaluation study. Up-to-date data and computer models were used, and public involvement continued through the reevaluation process.

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.
