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

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?

NC-2009 SSc6.1:Stormwater Design—Quantity Control

1-year and 2-year 24-hour Design Storm

Michael DeVuono, I've digged through both forum 6.1 and 6.2 but didn't found international data for Design Storm. I am doing a project in Russia. We have sites with existing imperviousness 50% or less and need this data for SSc6.1-1 and SSc6.1-2. Thank you for halping.

Liubov, there are several good resources posted in the Resources tab above that should help. (You'll need to log on as a paid member to access this and other LEEDuser, guidance, though.)

Tristan, I've checked all the Resources but cannot find any link regarding 1 and 2 year 24h design storm values outside USA (there are several for Oregon, Maryland, Colorado, etc). Could you point at a link or report for Europe or Russia? Liubov did you find any information for Russia? We have projects in Europe and Russia and this is currently such a tricky credit to fulfill, but only because of the specific regulations... Thanks!
