Per V4.1 BD+C beta guide "25% of the minimum 30% total outdoor space requirement must be planted with two or more types of vegetation". However, the guide does not specify the vegetation types, can turfgrass now be considered as one of the vegetation types?
As mentioned by Michael DeVuono in "LEEDuser's viewpoint" section :
Turf grass is no longer called out as noncompliant. Instead, the credit calls for “a diversity” of vegetation.
