If you want to make your neighbors happy maintaining a low array profile can mprove the aesthetics. You don't need a lot of ground clearance for vegetation maintenance like we do in the East so you could go for 2 ft clearance or even less.
Keeping the tiit angle low helps too. If you're net metered then there isn't any real penalty down to around 10 degrees tilt, below which soiling becomes significantly more of a problem. The other way to reduce array height is to install the modules in single rows in landscape. Many commercial rooftop PV support structures are designed that way and could be adapted for ground mount use.
I installed our array at 3 ft ground clearance and a 13 degrees tilt following the contour of our hill because it was both less expensive and because we like the way that looks.

It all depends on how accommodating you want to be.
