1119 Morse St NE – Green Roof

About the project

Date: September 14, 2022
Client: 1119-morse-st-ne
Address: 1119-morse-st-ne

Project Information This 7,544 SF 6” Modular System offers an ideal balance between performance and moderate structural load (30-45 lbs/ft²). It retains 50-75% of annual rainfall, meeting critical stormwater regulations, reduces HVAC costs by 10-30%, and supports a variety of plant palettes (sedums, grasses, perennials).
