Project Status as of August 2022

As part of the scope of this project, a study was first conducted to evaluate the flow of water heading towards Dickinson Bayou so various options for drainage improvements for the Gum Bayou Watershed could be considered and evaluated. As a result of the study, culverts were proposed at Columbia Memorial Parkway and League City Parkway and were also analyzed to determine the appropriate size to reduce ponding and the potential overflows. Hydrology and hydraulics (H&H) studies of Gum Bayou from League City Parkway (SH 96) to Dickinson Bayou and the existing Gum Bayou bridges were also conducted to determine possible improvements that would allow detention to better drain from the Bay Ridge subdivision. The consultant is now preparing the final design scope of work to be submitted to the City for review by mid-August. If accepted, staff will present the design contract to Council in September and subsequently, the consultant will begin the required final design and work with the U.S Army Corp of Engineers (USACE) to determine if an individual or nationwide permit is needed.
