Mason Creek Extension Project is Completed


October 20, 2005
Residents living in Katy can look forward to improved drainage, as the Harris County Flood Control District recently completed a $5.1 million project to extend Mason Creek and construct a stormwater detention basin.

The Mason Creek Extension Project is designed to provide residents on the east side of Katy in Harris County functional infrastructure that reduces the risk of flooding while incorporating environmental features, including enhanced wildlife habitat, wetland areas, thousands of trees and improved stormwater quality.



The project is a partnership between the District and the City of Katy. Construction on the project began in 2002 and ended last June. The project extended Mason Creek from its original end near Trotter Drive to the Katy Hockley Cutoff Road near Katy Park.

Stormwater Quality Features Bring Additional Benefits
The extension augments the area's existing roadside drainage system by providing better area-wide drainage and allowing roadside ditches to drain more quickly and efficiently. Water collected in the extension drains into a large stormwater detention basin, where three water quality ponds are specially designed to filter sediments and other impurities from the water before it enters the creek. All three ponds combined hold roughly 44 acre-feet of water.

"The District and Katy are pleased to help reduce flood risks and at the same time enhance the quality of stormwater in the area. Filtering sediments and other pollutants from stormwater provides a cleaner habitat for aquatic life and simultaneously maintains a channel's carrying capacity. It's a win-win situation," said Heather Saucier, spokeswoman for the District.

Trees Enhance Project Area
The District signed an inter-local agreement with Harris County Precinct 3 on Sept. 13 for the precinct to build park features on the entire project site. There also will be approximately 7,000 trees planted along the creek's extension and detention area.
