West Gum Bayou Drainage Improvements

West Gum Bayou Drainage Improvements project was funded through a Community Development Block Grant (CDBG) from the Texas General Land Office awarded to the City of Dickinson for infrastructure improvements due to damage from Hurricane Harvey. The area had a history of repetitive loss which means structural flooding more than once in the same location. More specifically, the roadways leading to the high school experienced frequent flooding that prevented access to and from the school. The project aimed to increase the storage capacity and conveyance in the channel and reduce structural and street flooding. 

Huitt-Zollars served as the prime engineering consultant. The design team provided grant application support, modeling, preliminary design, final design, bidding, and construction phase services. Associated Testing Laboratories performed the geotechnical investigation. Cypress Environmental Consulting prepared the environmental documentation including the USACE Nationwide Permit Pre-construction Notification.

The project consisted of 4,200 LF of channel improvements to the north side of the channel, three new detention ponds, and improvements to the channel culvert crossing at two roadways, California Avenue and Owens Drive. These improvements added capacity in the channel, provided additional storage in the ponds, and improved choke points in the system at the two roadway crossings making a significant impact on the area's drainage.
