We have a large site in an industrial park. We plan to include a 24 Acre parcel in our project site boundary that is owned by our client and part of this area will contain the water detention pond and the rest will be left in its existing field grass condition. The detention pond will have an adaptable pond seed mix applied with no irrigation. How should these areas be factored into our irrigation efficiency calcs. Since they are not irrigated will they help us achieve this credit, or will LEED consider this as turf which to my understanding requires irrigation?
