This document is the case study for the Brightview Senior Housing Development, Lake Tappan, NY, (METRIC). A limited footprint for stormwater drainage discussed.

The Brightview Senior Housing Development, a new nursing home complex, had a limited footprint for stormwater drainage that required 2.2 million liters (79,000 cubic feet) of water storage.

The development chose to utilize 458 MC-4500 StormTech Chambers that would be dispersed over four different areas. All of the systems would be installed under parking lots, which required the ability to handle top load strength for vehicles driving and parking on top of the system. In addition, StormTech Isolator Rows were part of the design. The Isolator Row catches sediment, so it can’t settle at the bottom of the bed. Nyloplast Inline Drains were used to capture the stormwater, while N-12 HDPE pipe was used to convey stormwater from the capture phase to the storage in the chamber systems.

The installation was done in Spring 2017 using 458 MC-4500 StormTech Chambers, N-12 Dual Wall HDPE Pipe, 14 Nyloplast Inline Drains.

Photographs of the project are included.
