The South Terrace

Pollution Control

Pollution Control

Based on studies by the US EPA, it is estimated that the South Terrace's green roof will remove 680 pounds of particulate matter pollution from the air annually.

Plant Purification

The perennial and Sedum species on the South Terrace remove the equivalent of 255 passenger cars’ worth of carbon dioxide and air pollutants from the atmosphere each year. The growing medium which supports the plants acts as a natural rainwater filter, restoring pH and removing hard metals like zinc and copper. By storing and re-evaporating up to 80% of the rainfall during storms, our green roof also reduces the burden on municipal drainage systems and helps to protect water quality.
