Three questions (Sorry about that last inadvertent post!):
1-The corporate campus on which my building sits has an NPDES demonstrating that the infiltration is =/> that of the pre-development site. Can we use this to qualify for SSC6 or do we still need to do the stormwater calcs?
2-The building is just one of a multi-building campus that shares impervious and pervious spaces, so whether we can use the NPDES or whether we need to do our own stormwater calcs according to the LEED SSC6 form, we will need to submit for the whole campus -- even though we're seeking certification of just one building. Is this acceptable or would this approach require a CIR?
3-How exactly can I use the Licensed Professional Exemption in this particular case? I have a stormwater specialist who is a P.E. What's the benefit of this exemption and what's required of him - besides his completing the LPE form?
Thanks much!!

Dianne,
Some responses:
1. I've seen previously conducted stormwater studies work to document this credit. It kind of depends on what information is included in the report, and whether it can be translated into showing management of at least 15% of the 2-yr, 24-hr volume.
2. In my experience, showing compliance on a campus-wide basis shouldn't be a problem. I'd recommend just making it really clear what the boundary is for the campus included in the stormwater analysis, and that the LEED project boundary falls completely within the larger campus boundary.
3. The form from LEED Online will show you exactly what documentation aspects you do not have to provide if you do an LPE exemption. In generally, the LPE exemption requires that you complete the associated form, and then you get a pass on providing a subset of the usual documentation. Which documentation is excused varies by credit, and the form will show this.
