700 & 605 Jackson Street

Flood resilient mixed-use

700 Jackson Street is a 14-story, 684,000 square foot mixed-use residential building with integral parking for 443 cars, located in Hoboken, NJ. The project includes 424 residential apartments including 42 affordable units, 30,000 square feet of ground level retail space, an outdoor pool, fitness center and other amenities. In addition to the residential complex, the project also includes 605 Jackson street building which is a 6,650 square foot gymnasium building and public outdoor spaces.

To combat the structural challenge of the residential tower overlapping with the parking levels below, The Harman Group’s team of engineers and parking experts worked collectively to design the optimal parking layout to allow for the maximum amount of parking while adhering to a cost-effective design.

The project site is located on Jackson Street by the Palisades Cliffs. This area was impacted by floodwaters during Superstorm Sandy. The 700 Jackson building is designed with a special flood proofing system to minimize the impact of such weather events. Flood proofing systems are a great measure for flood mitigation, but these systems create additional hydrostatic pressure build up below slabs on grade. Our design team is working on a structural slab on grade system that will resist this pressure in addition to interior load bearing flood walls and support for panelized flood barrier system around the retail perimeter of the building, that will hold water up to six feet above grade.

In addition, site subsurface conditions consist of loose fill, very soft peat and clay, which are highly compressible and are not suitable for support of the proposed structure with shallow foundations. Therefore the building loads will be transferred to bedrock using deep foundations.
