I live on a small lake. My backyard slopes about 30 deg toward the lake.
I would like to build a patio at the edge of the lake. The patio would be about 3 - 4 ft above the ground at its highest point. It will be about 3 ft wide and 12 ft long.
What do I need to build this patio using concrete blok?
Do I need to pour a footing or can I use block as the footing?
If I need to pour as footng how do I keep the cement from sliding down the hill?
Any other info would be appreciated.
Thanx
John

First check with the local building dept. most wetlands are protected sometimes with up to a 50' set-back.
Then I'd look at the blocks' web site that you will be using. They will have the best information on the type of interlock block.
...if you are refering to a cmu and it is 4' high you need to go to a soils engineer and a structural engineer to provide a design & stamp.
I would at any rate, if I were you. Soils on lake banks can be hard to read even for professional builders, and a retaining wall of this size needs an structural stamp for almost all locations. If it fails you could be in for quite a lawsuit, by others at the lake and if anyone /or thing gets hurt or damaged if it fails.
There are quite few points involved besides the design of the wall itself, such as deadman, steel reinforcing, the soil movement and presure, amount of moisture & perf. backflow diverters, run-off, grade of slope... and much much more.
