FAQs about SSc6.2 :

Why do the requirements focus on 1-year and 2-year, 24-hour storms?

Why include the 1-year storm in the credit requirements? Won't management practices for the 2-year storm be effective?

How can green roofs count as a stormwater control measure?

How can I achieve compliance if my project's stormwater control measures are outside the LEED project boundary?

I have 100-year data—how do I convert to 2-year?

Is it an acceptable strategy to capture the rainwater into tanks and discharge it into the public sewers after the rainstorm reducing the peak discharge?

Are there special considerations for international projects?

What performance threshold do I need to achieve for an Exemplary Performance point?

The calculations for this credit are always a headache! While our projects are usually awarded the credit, the equations in the LEED Reference Guide are helpful mostly for sizing a reservoir or cistern, but don't help you get to the final results. Does US

I have a project with a LEED site boundary that includes some undisturbed naturally forested area. How do I account for this area in stormwater quality calculations?

Does it route through a BMP?

No. It accounts for more than 50% of the LEED project site and naturally infiltrates water because it is undisturbed.

Tough to say without seeing this first hand, but, this credit leaves a lot up to the discretion of your CE, with the catch all that the approach should be acceptable within the locality. If I were working on this project, I would totally net out the undisturbed areas, and route only the disturbed area through the a BMP with 80% TSS removal.
