This may not belong here as it relates more to hardscaping, but let's see what you think:
A job we are working on requires a retaining wall of approximately 8'. "We" plan to build it out of mafia block (see below). A slope will intersect the face of wall perpendicularly, and cover it diagonally from one corner to the other (other diagram).
The plan is to create a substantial footing out of 3/4" crushed stone, and to have a 3' wide drainage space behind the wall - also filled with 3/4" crushed stone.
Soil is very sandy and well draining.
- Is this crazy?
- What should we be concerned about?
- Is this something that should get an engineer's stamp? (We're in NY)
