Current Projects

Jenkins Detention Pond

The Jenkins Detention Pond project involves channel improvements and mitigation to widen Hickory Slough along the District acquired 7-acre Jenkins tract between Roy Rd. & Garden Rd.

 

CR 130/CR 127 Detention Mitigation

This project consists of the design and construction new drainage ditches through the Pearland Regional Airport to provide drainage relief for CR 127 and regrading the roadside ditches along CR 130 to redirect flows towards Cowart Creek more efficiently.  The project includes construction of a detention pond adjacent to Cowarts Creek to mitigate the increased flows.  An MOU between the District, Brazoria County, and Pearland Regional Airport has established drainage easements necessary for the ditches and detention required.

Construction In Progress

Joe Martin Ditch Improvements

The improvements along Joe Martin Ditch will be broken down into segments.  This project includes regrading, installation of storm sewer pipe, and slope paving within the Joe Martin Ditch right-of-way from Mary’s Creek to Sleepy Hollow Dr.  Substantial erosion and siltation of the existing ditch is preventing the adjacent Woodcreek Subdivision storm sewer system from properly draining causing the system to retain excessive stormwater.

Garden Rd. Detention Pond

The District purchased approximately 27-acres at the end of Garden Rd. adjacent to Clear Creek for this regional flood mitigation basin in Brookside Village.  The first phase will consist of constructing a dry basin that will provide immediate benefit to the watershed.  Future phase(s) propose to expand the facility utilizing a pump system to maximize volume capacities.

Cannan Ditch Detention Pond

 

 

The District acquired approximately 43-acres adjacent to Cannan Ditch in an area that was identified in the District’s Master Drainage Plan as an area for regional detention.  The District will be able to create approximately 280 acre-feet of detention capacity in an area that has had flood problems in the past.

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.

West Lea Drainage Improvements

This project is part of a collaborative effort with the City of Pearland

The West Lea Drainage Improvements project will be a multi-phased project that will incorporate improvements to the interior of the West Lea subdivision drainage system, the drainage ditch that conveys storm water from the subdivision, and Mary’s Creek which is the receiving stream.

Mary’s Creek will be reconstructed to install in-line storage through benching sections on the north bank of the channel.  The extents of the channel benching will start from the weir at the West Mary’s Detention Basin to the channel crossing at Magnolia Pkwy.  A total of approximately 3,800 linear feet of benching will be constructed with stop blocks placed at an interval of approximately 500 feet in order to keep the channel conveyance similar to the existing condition, thereby creating additional storage in the floodplain with the benched sections.

The Mary’s Creek benching project will coincide with the rehabilitation of the West Lea Ditch and drainage improvements within the West Lea subdivision.  These improvements will not alter the runoff volume from the West Lea subdivision, only the timing of inflow into Mary’s Creek,  reducing the contribution of runoff to Mary’s Creek during peak times.  The benching section on Mary’s Creek will provide additional capacity without impacting the 100-year storm frequency.
