Byrnes Down Subdivision
Storm Water Improvement Project
Charleston, South Carolina
Like many low lying areas of the South Carolina coast, the Byrnes Down subdivision in Charleston experienced drainage challenges as the surrounding areas developed. The City studied the underlying engineering and easement issues throughout the late 1990ís and spent half a decade designing and permitting a solution to alleviate flooding in the quaint neighborhood of oak-lined streets and brick bungalows.
Chandler Construction Services, Inc. was pre-qualified to bid the project in 2004 based on experience with regimented construction schedules and past work in urban areas. In 2006, Chandler was awarded the $6 million dollar drainage improvement project. Construction is underway and is expected to be completed in 2007.
Throughout the project underground utilities will be relocated and public concerns will be managed to facilitate construction of more than 10,000 lineal feet of concrete drainage pipe and box culvert. SCDOT-approved traffic control, ecological awareness, storm water management, and scheduling remain instrumental in the successful completion of the project.
In the summer months the outfall structure was constructed under four active pressurized force mains. Demolition was initiated along Nicholson Street as 5x6 foot box culvert was installed on grade and utility conflicts were eliminated. In September, night work began as a 4x7 foot box culvert was extended across U.S. Highway 17N. Throughout upcoming months collector lines will be constructed and restoration work will begin.
