Oak Edge is a modern-age senior housing development in Memphis, Tennessee. The project consists of 50 cottages surrounding 107 independent-living apartments, 63 assisted-living units and 20 memory-care units.

With the new building and parking areas, a majority of the site is impervious; therefore, the need to capture stormwater was crucial. There is no area suitable for a retention pond, so storing the stormwater in a below-ground detention system was the best option. Corrugated metal pipe (CMP) offered the best option from a cost and design standpoint compared with RCP pipe and plastic chambers.

Contech Stormwater Design Engineers worked closely with Kimley Horn to determine the best layout configuration to maximize the storage volume in the smallest footprint. Contech used the Design Your Own Detention System online design tool to provide drawings to Kimley Horn reflecting the footprint and storage volume we were proposing. Two separate systems were designed. The first system is made from 2,800’ of 48” diameter aluminized CMP providing 34,948 CF of storage. The system is a single manifold consisting of 11 runs with bulkheads at the end. Each run is 251’ from the manifold to the bulkhead. The second system is made from 2,166’ of 96” diameter aluminized CMP providing 105,257 CF of storage. The system is a single manifold consisting of 9 runs with bulkheads at the end, and each run is 230’ from the manifold to the bulkhead.

The customer and contractor benefited from a single manifold design, as this reduced costs and lead times. Contech representatives were on-site during the installation to address any concerns the contractor has had. Acuff Enterprises backfilled the two systems with sand, and the installation was completed on time and without incident.
