We have a Group Project with a well defined and large LEED Boundary that has some formal landscaping with irrigation, some areas (i.e. steep slopes at grading) that have turfgrass with no irrigation, and a remaining area of undisturbed vegetation including fields and woods (no irrigation).

Throughout the Water Budget instructions, the term "designed landscape" is used when detailing the calculation approach and I assume this would suggest that the undisturbed fields and woods areas are excluded. Would this be an accurate interpretation of those instructions?

Many Thanks!
