Residents in the Avalon at Telfair may have noticed some work in the big ditch (known as Ditch H). The Fort Bend Drainage District is repairing the side slopes of the ditch to fix some naturally occurring erosion. The ditch is close to the FBCLID 17 East Levee so we wanted to give our residents an update of the work.
Natural erosion of Ditch “H” seems to be caused by multiple sand layers within the side slopes of the ditch. When water levels rise in the ditch, the fine sands get saturated and are carried away when the water levels recede in the ditch creating voids that result in erosion or “sloughing” of the side slopes. The District has been watching the erosion because of its proximity to the bottom of the District’s levee.
Although this erosion repair project is being done by the Fort Bend Drainage District, our FBCLID 17 worked closely with the Drainage District on possible options for repair. We helped to prioritize this erosion repair project by purchasing the timber pile material used for the project. In return, the Drainage District provided the labor and equipment to install the timber piles and to re-establish the side slopes. This work will be ongoing for a while to protect the side slopes of Ditch H and reduce erosion into our levee.
