We get quite a bit of rain around here, but screw anchors seem to last 
forever.  20, 30 years and you still see no corosion.  OTOH you don't want 
to plant them near a marsh.   I think a lot depends on the PH of the soil. 
You see a lot of lime sperad on farm land that was once swamp.

Again, it depends on how much rain and what kind of soil, but for me, I'd 
not use screw anchors except in an emergency or it they were the only viable 
method available. (or on a small tower)
