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.

Westminister Ditch

This project has been completed

Westminister (BBQ) Ditch is an existing drainage channel located just north of the intersection of FM 518 & Pearland Parkway.  The ditch is a grass-lined channel that drains east before discharging into Clear Creek.

The purpose of this project is to shift the ditch within District owned Right of Way in order to provide sufficient maintenance access on both sides of the channel.  The District will also rehabilitate and re-establish the slope of this ditch as well as replace failing outfalls.

Pre & During Construction


Clear Creek Reclamation Project

This project has been completed

This project’s scope is to remove approximately 90,000 yards of dirt from the Clear Creek channel creating a bench just above the static water level, thus creating additional detention within the banks of the channel.  This project continues and connects with a job completed last year just upstream that commenced one quarter mile south of the Barry Rose bridge.  The previous job was approximately one quarter mile in length, the current project is approximately one half mile in length.

Masonic Lodge Ditch

This project has been completed

The Brazoria Drainage District No. 4 is scheduled to begin drainage reclamation and maintenance activities on the Willowick drainage ditch and detention system in June 2019.

Project scope shall include, but is not limited to, ditch reclamation, concrete box culvert installation, and maintenance of the drainage ditch adjacent to Willowick subdivision. Included in this work is the reclamation of the drainage easement within the Willowick subdivision for maintenance access.

The initial phase of the project shall include drainage easement reclamation work consisting of the removal of trees, debris, and any encroachments upon the drainage easement. The drainage easement has been located and marked by a professional land surveyor. The drainage easement will be cleared of any encroachment including structures, fence, plantings, and any other obstructions to the operation and maintenance of the drainage facility. Property owners with identified encroachments will receive with this correspondence an exhibit reflecting the area of encroachment that will need to be remedied.

The Masonic Lodge Ditch job is a channel improvement project to restore 2,500 feet of open ditch from the rear of the CF Spencer Masonic Lodge on Walnut St. at the north and extending south to the recently completed Fite Rd. extension.  The installation of the box culvert storm sewer beneath the Fite Rd. extension made possible the improvements that this ditch has needed for some time.  The project scope includes the regrading of approximately 2,100 linear feet of open ditch, installation of 300 feet of concrete box culvert, and the replacement of failing outfall pipes from the Willowick subdivision.
