This District project included clearing and reestablishing the banks along a section of approximately 1,400 linear feet of Old Mary’s Creek starting at the Mary’s Creek Bypass.
This drainage project is part of the Texas Water Development Board grant program 75/25 local match agreement. The District was awarded the grant to enclose the ditch with reinforced concrete boxes and to construct mitigation ponds associated with the project. The goal of these improvements is to provide flood relief to the surrounding area and localized flooding which includes the neighborhoods of Willowcrest and Willowick.
This is a joint partnership project with the City of Pearland that will replace a full 120′ run and a partial run of RCP that has separated. Both runs will be straighten out the 30″ RCP. The District will also realign the open ditch to the south which flows into Old Mary’s Creek.
The District removed the failing rip-rap on the banks of Mary’s Creek at the bridge at Pearland Pkwy. and replaced it with concrete lining. The concrete will last a considerably longer length of time and allow for more efficient routine maintenance at that location.
The District will excavate benching areas along Mary’s Creek between FM 1128 & Magnolia Pkwy. These areas will expand the total capacity of the creek without causing a negative downstream or upstream impact.
This project is a precursor to the West Lea Ditch Improvements job.
The Orange St. Detention Pond was constructed as mitigation for the Mykawa Drainage Improvement project which included installation of a double row of 4′ x 10′ RCBs. Completion of the Mykawa project enclosed the ditch on the west side of Mykawa from Cherry St. to Orange St.

Orange St. Pond - Before & After
Town Ditch is being regraded and reseeded from Old Alvin Rd. to Pearland Pkwy. as part of the continued effort to improve drainage in the area.
Rogers Middle School Ditch was regraded and reseeded to improve flow and functionality.
The District has identified the need for improvements to the weir structures at the Bailey Detention Pond (south of Bailey; west of Wells Dr.) and the Cowart Diversion Detention Pond (between Veterans Dr. and Wells Dr.).
A drainage study of the Hood Ditch area was completed in August 2017 which identified several projects that would reduce flooding along Hood Ditch. The improvements at the Diversion Pond were included in this study and was used as a guide to scope this project.
The proposed optimization of the existing weir to Bailey Pond has also been identified by observations during rain events and the LOMR for Coward Creek Diversion improvements. These improvements will provide efficient use of the available volume in both ponds and will reduce the flooding risk to residents along the north/south streets between Bailey and CR 100.
