Current Projects

Longherridge Dr.

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

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.

Hickory Slough Improvements – Max Rd. to Silverlake Pkwy.

This purpose of this project is to clean out silt and repair the slopes as needed on Hickory Slough from Max Rd. to Silverlake Pkwy.  The portion from Max Rd. to Cullen Blvd. will focus on the removal of silt islands and build up.  Further west, from Cullen Blvd. to Silverlake Pkwy. the focus will be on slope repairs on the south side of Hickory Slough.

McHard Rd. Detention Pond

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

This detention facility is designed as a regional mitigation basin strictly for the benefit of the watershed with no availability to be sold or allocated for public of private projects as part of a joint project with the City of Pearland.  This area was identified in the Master Drainage Plan and the specific property was found to be available during the design process of the McHard Rd. Extension project.  It is approximately 35 acres and the volume will be maximized to provide ultimate benefits to the surrounding community.

Mimosa Acres/Willowcrest Detention Facility

The Mimosa Acres/Willowcrest Detention Facility will expand the currently constructed detention pond on the eastern portion of the property and connect it to the proposed detention pond on the western portion.  The ponds will utilize a pumped system to fully maximize the capacity and will provide additional flood mitigation for the surrounding neighborhoods of Mimosa Acres and Willowcrest.

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.

The ponds will be located at the BDD4 offices property on either sides of the back parking lot and shop.

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.
