This project has been completed
Due to devastating damage from Hurricane Harvey the Brazoria Drainage District No. 4 began channel improvements on Mary’s Creek in the Independence Park area. The first phase of improvements were from John Lizer Road to Liberty Drive near the old park entrance.
Once this section is complete work will continue on to other sections of the Creek. This project is necessary to stabilize the severely eroded banks of the channel and improve the conveyance of storm water during future flood events.
