(UPDATE: On December 4, 2018, Harris County Commissioners Court approved a $3,556,000 agreement with an engineering firm for final design of this project.)
F-52 Rehabilitation of Channels Upstream of Barker Reservoir
The Harris County Flood Control District has begun a major investigation of the current condition and capacity of all 13 channels for which it has property rights -- approximately 20 linear miles within Harris County -- that flow into the Barker Reservoir.
The goal of this project, funded by the 2018 Bond Program, is to assess and repair impacts from recent flood events on channels that carry stormwater into the federal reservoir. The project is limited to channels within Harris County and for which the Flood Control District has property rights.
Rainfall within the 126-square-mile Barker Reservoir watershed drains along 47 miles of open streams, including Mason Creek (T101-00-00) and Upper Buffalo Bayou (T100-00-00).
Bond Project F-52 is a “Local Only” bond project, which means there is no other funding partner at this time and total project costs would be paid with bond funding. Total allocation for this multi-stage project is currently $30 million on the Bond Project List.
In 2018, the Flood Control District began construction on a pilot project to remove sediment from four channels near Addicks Reservoir and to restore them to their design capacity. Results of the pilot project will be used to guide procedures and develop the budget for a wider effort in both the Addicks Reservoir and Barker Reservoir watersheds. A goal of this effort is to determine a cost per mile of channel de-silted and repaired. This cost data will be used to plan the work and budget on the 13 Barker Reservoir watershed channels, using funds from the 2018 Bond Program.
On January 30, 2018, Harris County Commissioners Court awarded a $13.32 million construction contract to Lecon Inc. for the Addicks pilot project. The four channels are:
- Horsepen Creek, formally identified as HCFCD Unit U106-00-00, from near Hamstead Park Drive to the reservoir;
- Bear Creek, HCFCD Unit U102-00-00, from Greenhouse Road to just inside the reservoir;
- Portions of Langham Creek, HCFCD Unit U100-00-00, from State Highway 6 to the reservoir; and
- HCFCD Unit U107-00-00, a Langham Creek tributary on the west side of the reservoir, near Hidden Springs Drive.
Part of the Flood Control District’s overall maintenance program, the study follows the Tax Day 2016 and Hurricane Harvey storms, which sent record levels of sediment-laden stormwater through the channels leading into the reservoirs, and caused severe erosion in some areas. Deposited sediment can impede stormwater outfalls and reduce the capacity of channels to carry stormwater.
Addicks and Barker reservoirs were built in west Harris County by the U.S. Army Corps of Engineers after disastrous floods of 1929 and 1935. They are designed to temporarily hold back stormwater and prevent damages along Buffalo Bayou, downtown Houston and the Port of Houston. Both reservoirs provide substantial storage capacity.
The Corps owns, operates and maintains the reservoirs, including the operation of outlet facilities that control discharges from the reservoirs into Buffalo Bayou. Most Flood Control District easements end at the limits of the federal-owned land.
