The City of Atlanta Department of Watershed Management selected Astra for the Construction Management at Risk (CMAR) delivery of Upper Proctor Creek Capacity Relief Project at Rodney Cook, Sr Park in Historic Vine City.

The project, located between Joseph E. Boone Boulevard, Walnut Street, Thurmond Street and Elm Street, addresses sewer system capacity relief for the Mineral Springs and Beckwith Street Trunks by collecting surface water runoff and redirecting the flow away from the combined sewer system.

The stormwater detention/retention facility consists of a pond, water quality features, storm drain pipelines, sidewalks and roadway improvements. Our scope included soil remediation, dewatering, utility coordination for water, storm, sewer, and telecommunications in a right-of-way, where we provided traffic control measures. 

The project also involved relocation water meters, rock excavation and restoration of landscaping for combined sewer system capacity relief. Components of the gravity sewer system included 880’ of 8” PVC pipe, 1100’ of 96” RCP, 1100’ of 10” DIP. The Department of Watershed Management is responsible for maintenance of the combined sewer system to facilitate proper drainage for the city public rights-of-way.

The site is a low area that was once populated with residential homes.  Today, most of the residential homes have been demolished but, many of the utilities are still in place. The project also includes soil remediation of the site and demolition of the remaining residences. Astra was responsible for oversight during construction of the entire project to ensure regulatory compliance with permits and approved remediation plans.

The scope of the project includes:

• Installing a new capacity relief storage facility and green infrastructure 
• Re-routing 1,100 LF of 96-inch combined trunk sewer
• Extending 48” storm sewer to the Georgia World Congress Center Parking lot 
• Installing pipeline and adjusting grade of streets in the project area 
• Soil remediation and utility relocation

JUSTIFICATION

• Enhances system operational efficiency and reliability
• Reduces frequency and cost of corrective and emergency maintenance 
• Provides essential capacity relief to the Beckwith combined sewer trunk
• Decreases frequency and magnitude of flooding in the vicinity of Rodney Cook, Sr. Park
