I think I might be over-engineering this but I live in CT and I'm also worried about snow weight. Adding a 8x10 deck attached to existing deck, 2x10's spaced 16" oc sitting on 3-2x10's supported by 4-6x6 posts. also adding cross bracing front to back on the 6x6's
Soil bearing capacity is between 3000 and 6000 psf. Thoughts?
