We are working on a project that includes a green roof. The design of the green roof incorporates 8 different native or adapted species, ranging from different grasses and sedum species to larger shrubs. The design, however, does not mix all species together: it creates different planting areas for different species, all within one large green roof area. Which means that all species are on the same green roof, but each one is planted in a group within its type. Would this count towards credit compliance?

The guidance in LEED Interpretation 10231 does not specify how the variety of species should be laid out. There is much greater emphasis on how the design will support wildlife habitat. Therefore, I think as long as you have an intensive roof system, where the depth of the growing medium is 6 inches or more, and you can explain how the native or adapted plants selected for the roof support the endemic wildlife populations of the site, your green roof design will comply with these credit requirements.
