Our landscaped site is approximately 80% natively, non-irrigated vegetated. However, 20% of our site landscape is forced (due to owner requirements) to irrigate grass in a fairly in-efficient way (would not meet LEED requirements).

My question is: does the 80% non-irrigated landscape outweigh the 20% even though the 20% irrigated is over the LEED efficiency threshold for that section? Or does the threshold violation disqualify us from the credit?
