LEED CREDIT 6.1 QUANTITY
LEED CREDIT 6.1 QUANTITY
(OP)
I have a site located in the County of Orange (California) with existing Imperviousness less than 50%. My question pertains to Leed Credit 6.1. Please see my questions below. I would greatly appreciate any feedback.
The requirement is to provide discharge rate and volume for the existing and proposed conditions. They require the 1 year and 2 year 24 hour events. Does anyone know how to determine the 1 year event? I have no problem with the 2 year event. I am using AES Ratscx. Thanks!

If you need another source for rainfall data try http://hdsc.nws.noaa.gov/hdsc/pfds/

You'll then have to print out and use the maps, which is cumbersome and inconvenient but is the best information available.
If that doesn't work, call Orange County and ask them if they have the data you need.
good luck

Thanks for clarifying. That is exactly where I stand. I will have to interpolate to determine the 1 year data, using the 2 year to 100 year IDF, as you suggest CVG. Or I can obtain precipitation data from the nearest rain gage, and develop my own 1 year precipitation from the data.
RE: LEED CREDIT 6.1 QUANTITY
Why not do this ? Might save you hours of work.
The website clearly says that NOAA 2 does have 1 year data but CG may be right and the website wrong. If CVG is correct wouldn't a call to whoever is requiring you to do these calculations ( is that Orange County ?) be the most direct route to an answer ?
good luck
