I’m designing an 8’ x 20’ deck that is 24’ above grade and attached to the house with a ledger board. There will be one deck beam opposite the ledger board that is comprised of two 2x8s. I’m planning on four 6x6 posts that are each set on top of 3 stacked 12’ x 12’ x 1.7” concrete pavers in 3’ deep holes (frost is not an issue). The 6x6 posts will be 11’ tall extending through the deck to accommodate railings and also support the beam for a pergola above the deck. Questions:
1. Would notching the 6x6 posts to accommodate the deck beam weaken them too much to provide adequate lateral / twisting support for the pergola?
2. Is back filling the post holes with gravel acceptable as opposed to concrete?
