Harris County Flood Control District works on projects all over the county, including projects near Pearland and Friendswood. Both the Mud Gully project and the Southbelt Detention Basin and Dagg Road project are making progress this spring.

Mud Gully

The concrete work on Mud Gully Channel is still on track to begin this spring. The project will be federally funded but overseen by the Harris County Flood Control District. The concrete in-line will be necessary, as the channel has been worn down over time due to erosion. An end date for construction has yet to be determined.

Timeline: spring 2020-TBD


Cost: $5 million
