Hillsborough, New Jersey is the ideal location for transportation and logistics. It is less than an hour from New York City and relatively close to Philadelphia and Allentown, PA. It is also close to multiple ports which are known cumulatively as PATH (Port Authority NY&NJ). In 2016 the PATH did $187 billion in imports and exports. There are also numerous airports (Newark, LaGuardia, JFK) and the goods arriving from these airports most be moved regionally. The newly constructed Midpoint Logistics fills this need by providing 423,000 square feet of warehouse space.  

A complex of this size and 100% impervious coverage needs a robust stormwater management system. Engineers at David A. Stires worked with Contech to develop an underground detention system made from 1,415 LF or 42” and 6,780 LF 60” Aluminized Steel Type2.  Corrugated metal pipe was chose based on its design flexibility, storage volume, service life, and cost.

A large amount of detention was required to store the required volume to mimic the predeveloped hydrology. In total, over 148,050 cf of storage was required, or 1.1 million gallons. This is equivalent to 1.67 olympic size swimming pools.

Regulations also called for water quality treatment. To meet this requirement five Jellyfish Filters were installed downstream of the detention system. This reduced the water quality volume by half, thus reducing size of the filters needed. 

Overall, the Contech design saved the owners approximately $300k versus alternate designs.
