"The new legislation will allow owners and developers the option of building 30% of roof space as green roofs, or a combination of green roofs and solar panels. The proposed ordinance builds on legislation requiring 15% roof space to be set aside for solar panels adopted earlier in 2016, and allows owners and developers to implement two square feet of green roofs instead of one square foot of solar panels if they wish."
The green roof includes a combination of intensive (8 inch) plantings and extensive (4.25 inch) green roof areas. The LiveRoof installation was performed by

We have developed a patented "hybrid" modular system which combines the best features of all existing types of green roofing. LiveRoof provides the Natural Function and Natural Beauty of "built in place" green roof systems but without the extensive ongoing costs of maturation. LiveRoof offers the speed of installation of modules but without grid lines or compartmentalization of soil. LiveRoof systems offer the prevegetation of carpet or sod-like green roof systems but with a broader plant palette and without the need for excessive watering and maintenance required by mat systems (for establishment).
We populate each module with locally blended engineered soils and locally selected and grown RoofTop Proven™ plants, under the care of local professional horticulturists. Our grower network has over 500 years collective experience in horticulture, and each local licensed grower typically has decades of experience growing plants in the local climate, and uses this knowledge to select the right plants for the unique challenges of each project. We also have over a dozen Accredited Green Roof Professionals (GRP) in our network and our professional representatives provide industry leading support.
LiveRoof is also an industry leader in research, and our green roof system was the first to receive FM Approval, a Class A Fire Rating, and to conduct Full Scale Wind Uplift testing. Our organization has bred, selected and introduced dozens of plants specifically for thriving under the rigorous challenges of rooftop environments. We have supported institutions in researching optimum stormwater management, the most effective irrigation methods, and much more.
