that the top of the foundation be a maximum of 8" above grade with a full 8'

specify that the area under the base plate be grouted after the tower is
installed, which is probably to keep water off of the mounting bolts.
Actually you use non-shrink grout and the grout becomes a
supporting part of the tower so that not all of the forces are on the bolts.
