Is there away, with parcels, to take an area with the labels; create different C Coef. and then average them?
EX.
I would have a Site / Grass/ Under there i would place all the grass parcels with associated labels
Site / Pavement / Same as above
Site / Roof / Same as above
I can then hopefully, with all the parcels, I can average the C Coef. to get it averaged or a weighed number.
I figured if this works, we can use this for our existing conditions, and possibly storm sewer calcs.
Thanks for your help!
