Inquiry

Using LEED-NC 2.2 & applying the on-campus application guide for a new building in an existing campus setting, can credits 6.1 & 6.2 be met by an analysis of an existing on-campus detention pond constructed at the time of original campus construction (1970\'s), provided that the pond meets or is upgraded to meet these requirements? If not isn\'t LEED punishing the institutions that had the foresight to plan effectively and implement appropriate storm drainage practices before it was the popular thing to do? The proposed approach would use the native lands prior to 1970 as the pre-development site condition (imperviousness less than 50%) and require that post-campus construction storm water (including all existing & future planned buildings / improvements) meet the requirements of 6.1 & 6.2. Should the existing pond prove adequate to meet the requirements then the project could count the credits, if not then improvements to the existing pond could be made to meet the requirements and achieve the credits.
