Hello LEEDuser Community!
I have two questions related to calculating the 25% Vegetated Space for the Sustainable Sites Credit in LEED v4.0:
(1) If we are landscaping using a mixture of gravel with bushes, how do we calculate the amount of vegetated space? Can we count the entire area enclosed by the gravel/bushes mixture or do we have to exclude the gravel? Also, the bushes will grow over time and thus their amount of their "ground coverage" will increase over time. So, how has LEED historically handled this situation?
(2) While I understand that turf-grass doesn't count towards the 25% of vegetative space, would something like ice-plants be acceptable?
