Im getting ready to build a 9 foot block wall. 13 courses high. The first four courses are 8 x 8 x 16 for a retaining wall. The remainder of the wall will be 6 x 8 x 16 and 9 courses high.
What are the required dimensions of the footer and how many inches of compaction will I need?

That's a monster retaining wall. When were you planning to start?
