I have a fence that runs down the side of my corner property with a pavement (~1m wide) and road on the other side.
The alleyway between fence and house is 2.2m wide.
There is a drop of ~800mm from the pavement level to the nominal garden grade.
This has been handled by an embankment and/or sleeper retaining wall with 1m of raised planter.
I want to terminate the planter to the fence where the below image is taken and dig out everything to the left as close to the fence as possible and add a masonry retaining wall.
Question time:
I will, hopefully, at some point in the future, be digging a pool just inside of this and will need to set the footing ~ 1m deep so they don't get in the way of future excavations.

Question time:
- What regulations exist for retaining walls bordering a highway, but still within my boundry?
- My provisional plan was 140mm CMUs, rebar @ filled, does this seem suitable or should I go up to 215? - I figured the 1m of pavement should offset any direct vehicle load spread.
- I was going to put in a single 32mm drainage pipe down the length of the back of the wall (about 6m) and have a single drainage point through the wall - would this be acceptable?
