NC-v4 SSc4:Rainwater management

Option 2

Hello, I wonder how should I understand Opt.2 BD+C Rain water Mgmt credit. "Manage on site the annual increase in runoff volume from the natural land cover condition to the post-developed condition." Does that mean that I should design the site so that it can help increase annual runoff volume and stays in such condition all the way thru post-developed condition, given the base line is "natural land cover condition" ?

Thank you Michael, it's much clearer the way you said it.

Hi, I am not sure about the definition of "natural land cover condition" and which predevelopment conditions should be used. If the pre Development site, for example, is a parking lot, the Pre Development Volume is the volume from parking lot or from the same site before any land modification was undertaken "Natural"? Thank you.

Natural Condition = What your site was in the Stone Age, before it was touched by man.
