Project Description

Construction began in late 2020 on a project to widen and deepen a segment of Armand Bayou from Sam Houston Tollway East to Spencer Highway. The Harris County Flood Control District is working with the Harris County Toll Road Authority on the project, in connection with a HCTRA project to expand the toll road.

HCTRA will fund the channel project, which is being managed by the Flood Control District.

Channel improvements along this 2,300-foot section of Armand Bayou will mitigate for increased stormwater flows as a result of the road project. The new design will deepen and widen the channel to allow for storm sewer outfall from HCTRA’s tollway widening.

The current V-shaped channel has an average depth of about 6 feet, with a bank-to-bank channel width that varies between 20 feet and 30 feet.

The proposed channel will have a trapezoidal (flat-bottom) cross-section, with an average depth of 8 feet and a bottom width of 61 feet. The bank-to-bank channel width is as much as 122 feet.

Property along the channel was acquired to widen the current 30-foot channel corridor to a maximum of 182 feet, including maintenance berms that will allow for future routine maintenance access.

Natural stable channel design features of the new channel will improve its environmental value, while also working to stabilize the slopes. These environmentally friendly features include using natural root balls to armor the “toe” of the bayou banks, and using a series of pools and rock riffles to slow the water and reduce erosion. This new reach of Armand Bayou will have room to meander more naturally within the channel corridor.
