>  I looked more closely at the US Tower foundation plans and  they specify 
that the top of the foundation be a maximum of 8" above grade  with a full 8' 
below grade.  A minimum above grade dimension is not  specified.  They also 
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.
