Project Narrative: New Bedford’s first green roof was installed on the new addition to the city’s Hastings Keith federal office building. The 3,400 ft² green roof is designed to help reduce pollution and to provide protection for the new EPDM roof membrane. In addition, the plantings provide an aesthetic benefit to the building occupants with offices above the roof.

The extensive green roof was designed by Oak Point Associates and features alternating curvi-linear bands of five plant species. These included: Achillea x ‘Moonshine,’ Festuca amethystine ‘Superba,’ Sedum spurium ‘Bronze Carpet,’ Sedum spectabile ‘Autumn Joy,’ and Festuca glauca ‘Elijah Blue.’
