I have 3 parking lots which are comprised of gravel (chat)....what would the coefficient for this be? I believe it should be less than any kind of pavement but more than grass.

Steve, I'd say this is highly variable. It would depend a lot on the type and size of gravel, and the characteristics of the sub-base. I think you have the right idea, but obviously that leaves a lot of variability.
