Our Project Story

Uline’s NYC/PHILA branch is located between Hamilton Boulevard and the Route 222 bypass on a parcel of about 200 acres in western Lehigh County that spans both Upper Macungie and Lower Macungie Townships.

Developed by Liberty for Uline, a leading distributor of shipping, industrial and packaging materials, the facility encompasses two buildings that range in size from 1.19 million SF to 1.28 million square feet, including 70,000 square feet of office space. From this location, Uline serves East Coast customers from Maine to Washington, DC.

Isett was the site/civil engineer on the project, which also required extensive traffic improvements due to the increased traffic flow from the site. Isett’s traffic engineers conducted numerous traffic studies, designed roadway improvements including turn lanes along Cetronia Road, Mill Creek Road, and Grange Road and designed new and upgraded existing traffic signals. Structural engineering design by Isett featured tilt-up construction of pre-engineered panels.

The extensive campus also features a network of walking trails which Isett designed, as well as extensive campus landscape plans that include the planting of red oak and evergreen trees to provide screening.

Isett’s Environmental Consulting department conducted environmental and wetland assessments and prepared PA Natural Diversity Index (PNDI) and Cultural Resources Reports required by state agencies.
