TERRA engineered the sitework and stormwater detention for this large scale, 13-acre phased CHA development. The project is located on South State Street between 27th and 30th Street in the City of Chicago. The existing 16 buildings are being renovated and the entire site is being completely renovated inclusive of the private driveways and fire lane running through the development. Work included the design, coordination, and relocation of all new underground utilities for site including the electrical, gas, storm sewer and water services for the site and the buildings. TERRA’s design included a new 2,000 LF private water main to service each of the buildings.

TERRA provided storm water detention for the entire site through the use of an underground, prefabricated, concrete detention tank by StormTrap. This was a pilot project for the Department of Water Management. TERRA worked closely with the DWM to research the effects of placing this system in part below the ground water table. To do this, TERRA designed a waterproof system that satisfied all of the department’s requirements. Each phase has been permitted individually through the Chicago Department of Water Management (DWM) – Sewer Section.

TERRA designed the overall site concept and landscape layout. The pre-existing flow of the pedestrian traffic was examined to provide a more aesthetic and efficient site layout. The site landscape design was permitted per the City of Chicago Landscape ordinance.

TERRA permitted the project through the City of Chicago – Department of Buildings and the Chicago Department of Transportation.

TERRA provided construction services for the project throughout each of the phases including site observations during civil design installations, reviewing of product submittals, and coordination with the design team to respond to RFIs and unforeseen conditions upon excavation.
