Airport Road Properties engaged CP to assist with their plans to expand the available leased space at their facility in Sussex County, New Jersey on two separate occasions (2015 and 2023/24). The projects included both design and permitting services for the construction of three new flex space commercial buildings (two in 2015 and one in 2023/24) and the associated site improvements, which includes a new on-site septic system (2015) and expansion of the septic system (2023/24) to serve all three of the buildings. Updated stormwater design to accommodate the latest building addressed the revised NJDEP Stormwater Management Rules (2023). The end result of the project more than doubled the available leased space for the client at this location. Significant grade differences on the property required design of a number of rockery/stone retaining walls to provide level areas for the flex buildings and associated parking areas.
