Boston’s 101 Seaport–a 17-story, 440,000-sq.-ft. office building–is topped off with 5,000 sq. ft. of living roof that will reduce the need for onsite stormwater management systems. The soil in the green roof system, made by LiveRoof and designed by Copley Wolff Design Group, Landscape Architects and Planners, acts like a sponge and absorbs excess rainwater, thus reducing the impact of a new building on the municipal storm drainage system and surrounding watershed by reducing flooding and erosion.
