If so, is native material acceptable backfill over the top of that last 5’ wide section of the foundation?

RESPONSE: The additional foundation excavation width of 5-ft is correctly shown on the plans. The total base foundation width is (4-ft of Bench Width) + (8-ft [min] + 12-inches of reinforcement support) + (5-ft of additional base foundation).
