Powell Drive & Persimmon Place Corridor (Scott Drive to Rowlett Road)
This localized infrastructure improvement project focused on the complete reconstruction of approximately 1,650 linear feet (L.F.) of a residential alleyway with a typical width of 10 feet. The newly engineered structural profile features an inverted 8-inch x 5-inch x 8-inch (3-inch invert) reinforced concrete pavement section supported by a durable lime-stabilized, compacted subgrade layer.
The legacy alley corridors offered highly restrictive, minimal underground storage capacity for adequate stormwater conveyance, elevating flash flood risks for the adjacent residential properties.
To mitigate this liability, BHC engineered the alley infrastructure improvements to robustly accommodate a rigorous 100-year design storm event. This was accomplished by implementing an integrated hydrodynamic system: leveraging controlled surface storage via custom "V"-shaped inverted alley sections, optimizing localized drainage inlets, and routing overflow securely into a newly upsized subsurface underground storm drainage system.
