Surface to Elevation

I’ve got two borrow locations that I can dispose of excavated material. I ran a Surface to Elevation and used Original Ground to Elevation 25.0’. Does the report compute the available volume beneath elevation 25.0’?

I think this answers my question. From TBC Help:

Surface to Elevation - Select to generate a comparison of the volume formed by comparing one surface to a flat plane defined by the user giving its elevation.

The ‘Volumes Above/Beneath 25.00’ are the calculated from original ground to Elevation 25.0’. Therefore, I have approximately 80k CY capacity for disposal.
