[USCC] Runoff Reduction

Thu Jan 22 12:53:39 CST 2009

Sandy,

I know what you are talking about. I am the person in charge of Marketing 
the Dano Drum in the Americas. Also, I am a CPESC (Certified in 
Professional and Erosion Control) and CFM (Certified Floatplane Manager).

Let me give you some links. EPA and the Water Quality Department haven't 
granted a special CN (Curve Number) to the Compost yet. This probably will 
come from the USDA - NRCS, which are the ones that came with the TR-55 and 
TR-20 software. USDA-NRCS is also the one from where we take the Curve 
Numbers for either Agriculture or Urban Erosion.

[USCC] runoff reduction
Are there any studies out there that prove there is a reduction in curve
number if a "green space" has a compost blanket rather than just mulch or
matting?  If so what would that curve number be and also what kind of 
credit
can you get for infiltration.

Re: [USCC] runoff reduction

There are a few published studies on compost blankets that quantify their 
effect on runoff volume (among other storm water characteristics). These 
studies report rainfall and runoff amounts. If rainfall and runoff depth 
are known, you can calculate the runoff curve number (CN) based on the 
USDA-SCS TR55 methodology. Based on the values reported in these studies, 
an average CN of 55 has been determined for hydrologic soil group B.  This 
CN is similar to a public green space, 75% brush covered area, and a 
woodland according to CN book values provided by the USDA SCS TR55. 

I am not sure I understand your question about obtaining credit for 
infiltration. Are you trying to calculate infiltration or rainfall 
absorption of a compost blanket?Dr. Britt Faucette, Ecologist, CPESC, LEED
