Roy Rd. Detention Pond

The Roy Rd. Detention Pond project is located at the dead end of Roy Rd. adjacent to the south side of Clear Creek in Brookside Village.  It will encompass the District acquired 14.335 acre Taha tract (purchased in FY 2020) and the previously acquired 4.13 acre Loonam tract allowing for a potential total of 18.465 surface acres of detention area and will provide additional flood mitigation for that area in Brookside Village.

Mary’s Creek Channel Lining @ Pearland Pkwy.

This project has been completed

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.

Mary’s Creek Benching

This project has been completed

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.

Orange St. Detention Pond

This project has been completed

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.

This 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.
