C-03 Federal Flood Risk Reduction Project

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, 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 local sponsors 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 bridges (except for railroads); 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.

In 2013, the Corps completed a General Reevaluation Report (GRR), which presents an alternative to the Clear Creek Federal Project that was 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)
  • 20.4 miles of channel improvements along Clear Creek, Mud Gully, Turkey Creek and Mary’s Creek.
  • 500 acre-feet of in-line stormwater detention along Clear Creek.
  • 14 bridge replacements or modifications
  • Environmental enhancements.

RECENT ACTION

July 30, 2019 – Harris County Commissioners Court authorized an additional $1.9 million for surveying services in support of this project.

On June 4, 2019, Harris County Commissioners Court authorized execution of a Project Partnership Agreement between the Harris County Flood Control District and U.S. Army Corps of Engineers in connection with this project. Commissioners Court also authorized negotiation of interlocal agreements with Brazoria Drainage District No. 4 and Galveston County to share the non-federal costs and the operations and maintenance responsibilities of the project. Commissioners Court also approved an agreement not to exceed $750,000 with an engineering firm for engineering services and hydraulic and hydrologic analyses.

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 $187 million in federal funds to complete the project.

Project construction is expected to start in late 2019.

Brief History of the Project

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.
