Undertaken by Columbia-based U.S. Group Inc., the $5.5 million project involves installation of underground storage chambers designed to channel away storm water runoff. The project also involves designing a landscaped parking area with a variety of native trees.
The company installed more than 2,500 yellow storm water chambers about 5 feet underground, each of which allows rainwater to soak into the ground underneath the parking area. The project also saw placing a system of pipes alongside the chambers on top of gravel beds and filtration matting throughout the project. Pollution filtration devices were also installed to ensure that the lot was environmentally friendly.
Advanced Drainage Systems Inc., headquartered in Hilliard, Ohio, manufactured the entire system. Jeff Kinard, the senior design engineer of the U.S. Group and project manager for the job, was reported stating that U.S. Group came up with the largest invisible land saver systems.
Kinard adds that with the underside of the chamber open, a large area of storage is available and the present crushed stone completely encapsulates the system and goes to a minimum of six inches above it. He explains that whenever it rains, the water flows into those land saver units and soaks into the ground.
Soth Carolina-based Corbett Concrete Construction and Columbia-based C.R. Jackson assisted the U.S. Group, who were in charge of putting in the more than 17.7km of curb and gutter work at the parking area, and the paving, respectively.
