NC-2009 SSc6.1: Stormwater Design—Quantity Control
Sorry, might be a stupid question:
in our case the pre-development is a demolished building complex.
Do we calculate the post-development against the previous development or the undeveloped conditions?
Thanks

As far as LEED goes, your pre-development is based on what is on the ground right now, before you start construction. However, check with your local regs, as well as NPDES requirements, which usually make you take a portion or all of existing impervious or other cover types back to meadow.
