A drainage study was completed in 2018 for areas of the Settlers Park subdivision post Hurricane Harvey. These areas regularly experience excessive street ponding during major storm events. The study identified multiple areas that far exceeded the city's performance criteria within the Master Drainage Plan and they have been programmed in phases in the current capital improvement program.
This project will involve constructing a new storm drainage outfall into LID 2 Ditch “C”, replacement of storm sewer, water mains, concrete roadways reconstruction and replacement of sidewalks along portions of Mesquite Drive, Sleepy Hollow Drive and Green Fields Drive within the Settlers Park Subdivision.
After project completion, the area will see a reduction in the ponding depths and times during major rain events along with a general improvement in driving conditions on the roads.
Halff & Associates, Inc., was selected through an RFQ process as the consultant to perform the engineering services required for this project. This selection was in accordance with City Policy PU-109 for procurement of professional services.
