The details of option 3 are presented below.
Cut-fill maps have been created at a 1/10th foot drop per 100 feet with a cut-fill ratio of 1.3. The cut fill values are outlined in the following table. Piping estimations are approximate, but additional piping may be needed, though the total amount probably will not make much of a difference from the estimations presented here.
The cut fill map for option 3 is given below.
