Federal Flood Risk Reduction Project – Clear Creek

The Clear Creek Federal Flood Damage Reduction Project is a partnership project between the U.S. Army Corps of Engineers, the Harris County Flood Control District, Galveston County, and Brazoria Drainage District No. 4.  As of the June 2019 Project Partnership Agreement between the Corps and the Harris County Flood Control District, the Flood Control District is the lead agency for this project, under a non-federal implementation pilot program authorized by Section 1043(b) of the Water Resources Reform and Development Act (WRRDA) of 2014.

Flood Warning System

Harris County Flood Warning System

In 2018 Brazoria Drainage District No. 4, through the use of a Memorandum of Understanding (MOU) with the City of Pearland and an Inter-local agreement with the Harris County Flood Control District, installed 8 new rain/storm gauges throughout the district (map of gauge locations).

The purpose of this project was to remove the old gauges that the City of Pearland owned and replace them with the newest technology in order to give residents within our jurisdiction real-time monitoring of our local streams and bayous.  The data includes water levels, rainfall amount, historical flooding data, a visual cross-section of the associated drainage channel, and our benchmark information at each gauge station.

When it begins to rain, data-collecting sensors at each gauge station transmit rainfall amounts via radio frequency every time 0.04 inches of rain is measured by the sensor. Sensors that transmit bayou/stream levels report every 0.10 foot rise in water levels.  The sensors transmit information to four primary repeaters located in the Huffman, Clodine, League City, and Tomball areas.The repeaters then relay the data to primary and back-up base stations located at Houston Transtar and at the Harris County Appraisal District. The information is monitored daily by software and by Flood Control District staff to ensure the gauges are properly functioning and transmitting accurate data.

Update: We have are in the process of adding 8 new locations around our District.  Check out the latest map and get live updates via text or email at the Harris County Flood Warning System site:

Westminister Ditch

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.

Country Place Ditch

Brazoria Drainage District No. 4 is scheduled to begin drainage reclamation and maintenance activities on the Country Place, The Lakes at Country Place, and Southdown drainage ditch in July 2019.

Project scope shall include, but is not limited to, Drainage Right of Way reclamation, outfall repairs, and maintenance of the drainage ditch adjacent to Country Place, The Lakes at Country Place, and Southdown subdivisions.

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 Right of Way. The Drainage Right of Way has been located by a professional land surveyor. The Drainage Right of Way will be cleared of any encroachment including structures, fence, plantings, and any other obstructions to the operation and maintenance of the drainage facility.

The drainage channel known as Country Place/Southdown Ditch extends from State Highway 288 east, then turning north to outfall into Clear Creek.  The neighborhoods to the north and south of this ditch began construction in the early 1980s.  The outfall pipes from those neighborhoods have needed repairs or replacement for several years.  This project will first address those failing outfall pipes and structures from Country Place and Southdown, then will refocus to regrading of the channel.

This project is scheduled to start in July 2019


Government Ditch

This is an inter-local project with Brazoria County to clean out and improve approximately 2.3 miles of a drainage ditch extending from FM 1462 in Rosharon, south to County Road 655 on the Ramsey and Jester state farm property.  This ditch is located in an area that does not currently have Drainage District representation.

This job has been completed.

Springfield Ditch

Springfield Ditch & Park Village Detention Pond

The detention facilities for the neighborhoods of Springfield and Park Village have been plagued with drainage difficulties for many years.  In an effort to more effectively drain these facilities, the District engineered and has nearly completed a project that combined the two detention ponds with the drainage channel that was located between the ponds.  This design addressed the drainage concerns, replaced failing outfall pipes, and simplified the maintenance burden in perpetuity.

This project is near completion with only hydro-mulch grass seeding left to finish.
