NC-2009 SSc6.1: Stormwater Design—Quantity Control
My project is using Option 1: Design stroms,Case 2 :Site with existing imperviousness mote than 50%
LEED online template V 5.0 Table 6.1-3 Site runoff: Two year,24 hour Design storm quantity is requested to fill in cf/storm
Just wish to re-confirm that the cf/storm stand for cubic feet per storm?
Civil engineer had provided me a value in cubic meter 8900m3 per storm.
Am I correct to fill that in form as 314300 cf/storm (using 1 cubic foot = 0.02831685 cubic meter)
Thank you

Why do the requirements focus on 1-year and 2-year, 24-hour storms?
How can green roofs count as a stormwater control measure?
I have 100-year data—how do I convert to 2-year?
Are there special considerations for international projects?
What performance threshold do I need to achieve for an Exemplary Performance point?

Thank you Michael .
LEED 2009 NC online template version 5 mentions cf/storm and not cfs.
am i missing something?
How to convert m3 into cubic feet/sec now?

It appears they are looking for total volume (quantity), not the rate, if that is the case the units are simply CF, convert your m^3 to f^3. I would put the total volume in this block and move on.
CF/sec measures the rate, the volume that runs off per second.
I am working on cleaning up a lot of this language for v4, so it is in actual engineering terminology.
