first question.. is the 4 square for 80m (in which case 3 feet is in the 
noise) or for 2m, (in which case it's not...

if you're on 40m, a quarter wavelength is, what, about 33 ft, so you're 
talking 1/40th of a wavelength with 3 ft.. probably not an issue. Probably 
not even an issue with 20m (unless you have some sort of exotic phasing 
system that will be picky about tiny changes in mutual Z, and then, you 
have much bigger problems to worry about)

I'd guess that the small scale slopes will have less effect than other 
things around (horses, towers, etc.).

It's actually,
