Hi All, 

Can there be absolutely no uncontrolled flow to achieve this credit? For example, if the required retention volume for the 95th percentile storm is 100 CF, can I oversize ...

Hashir Usman LEEDuser Basic Member May 5, 2020- 8:18 am Hi Andrea, LEED Guide says ''All runoff from the chosen percentile of precipitation events must be managed such that there is no surface discharge from the site. Techniques include, but are not limited to, infiltration, storage and re-use, bioretention, open-grid pavement, and the reduction of impervious area.'' So, I guess it is to use all those techniques that best mimic the natural hydrological conditions before any development occurred. And I read it in this forum that only storing and reusing the runoff volume does not comply...
