Our project is located in a small, tight suburban lot. The only landscape requirements within the zoning information is that A) 5% of the parking lot must be landscaped, B) any retention areas must be landscaped (not within our site boundary) and C) the landscape setbacks must be landscaped (also not within our site boundary.) Basically our landscaped area = 20% of our parking lot paved area. We think this meets the requirement for SSc5.2, BUT are worried that LEED will make us use the 20% of the site area. Which we do not meet - we are currently landscaped 12% of our site area. But if we follow our 5% zoning number we are eligible for the credit and also eligible for the exemplary performance. Any advice here?
