Mike,
I would like to reqest two slope functions for v11.

First I would like to have a function to calculate the average slope of a polygon. (S% =(0.0023xIxL)/A
Where:
S = Average natural slope of parcel in percent
I = Contour interval of map in feet, with contour intervals to be five feet or less
L = Total length of the contour lines within the parcel in feet
A = Area of the parcel in acres
0.0023 = Constant which converts square feet into acres

Second, I would like the slope also expressed in % in the Path/Profile tool.
I would also like to see the watershed calculation tool suggested in a previous post.
Thanks, John
