Hi All. This is just a suggestion. To achieving this credit the pre-development condition is no more the "existing site" we were talking about in v2009, but is now(LEED v4) the "natural land cover condition". It sounds similar but the treshold to reach is now very higher. Am i wrong? I think it will be very expensive for the Contractors to set back the site's rainwater impacts to the Age of Stone.

LEED v4 is actually a much more achievable SWM target than in previous versions of LEED, and some may argue, as step backwards. As for cost, if the project is located in the US, there are most likely much more stringent SWM requirements in place at the local level. But modeling a site in a Pre vs. Post condition is hardly some groundbreaking engineering requirements. We have been doing this for decades.
