TERRA engineered the site plans for stormwater management of the development on the “Poetry Foundation” property. As the project’s site was a lot-to-lot building, TERRA accommodated stormwater detention in two ways. One, TERRA engineered a 2,353 CF concrete storm tank beneath the building. Two, TERRA provided a nine-inch-wide French drain system along the northern facade, abutting the city sidewalk. The French drain allowed TERRA to meet CDWM volume control requirements in an indiscrete way, not distracting from the architectural detailing. The French drain is comprised of filter fabric wrapped aggregates and a perforated pipe under drain. This design was permitted through the Chicago Department of Water Management (DWM) – Sewer Section to verify 2009 regulation requirements were met.
TERRA provided construction services for the project, including site observations during civil design installations, review of product submittals and coordination with the design team to respond to RFIs.
