Town Ditch Improvements – Old Alvin Rd. to Pearland Pkwy.

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.

Construction Complete

Rogers Middle School Ditch

This project has been completed

Rogers Middle School Ditch was regraded and reseeded to improve flow and functionality.

Country Place Detention Basin

This detention pond will be located on a 20.031-acre tract near Country Place ditch and Clear Creek.  This project is located in the Country Place development adjacent to both Country Place Ditch and Clear Creek.  The total area of the tract will be fully utilized for flood mitigation and will provide additional detention storage in the area.

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.

Harrison Rogers Detention Facility

The recently dedicated Harrison Rogers Detention Facility will deepen 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.

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

Cowart/Bailey Pond Weir Improvement Project

This project has been completed

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.

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.

Installation of Drainage Improvements

Sand Pit Policy

The District has adopted a new Sand Pit Policy for all sand pit’s within our jurisdiction effective December 1, 2021.  Each sand pit is required to renew their discharge permit through the District on an annual basis.  See the attached document below.

Acknowledgement Form

An Acknowledgement Form will need to be filled out and signed for all new and re-development.

Maintenance Declaration

A Maintenance Declaration will be required for all new and re-development.  The Maintenance Declaration must be signed and notarized by the owner of the property and the original delivered to the District offices.

With the Declaration a developer will need to provide a Maintenance Plan (example below) and exhibit (survey) for the property.  All three documents will be filed in the Real Property Records with Brazoria County.
