[TowerTalk] base below ground level/drainage

[Roger (K8RI)]

Assuming you have the room, just dig out around the tower base, say 6" or so 
and out about 10'. put in pea gravel up to within about 2" of the top of the 
base. Make sure the area is well drained.  Then the area can be used to 
plant shrubs or flowers. If you move you take the tower down, and fill the 
area over the concrete with mulch, pea gravel, or resod the whole thing.
