Talking Retaining wall foundation question

I am located in South Seattle and would like to build a forty inch high retaining wall. I will be using the eight inch high by seventeen inch wide and twelve inch deep decorative cinder block style blocks from Lowe's to complete the project. These blocks also have a lip at the back on the bottom for reinforcement. I will be placing a three foot tall chain link fence on top and filling the center holes with concrete at a five foot spacing. What kind of footer or foundation, if any will I need?

You can never go wrong pouring some sort of footer. Weather you use a stone base or concrete. Dont know much about landscape block but regular block definatly need a concrete footer below frostline if you have that issue there

Find the manufacturer's website and installation instructions. It should have foundation/footer requirements which most likely will be compacted crushed stone.
