We thought our retaining wall would be below a metre but on further investigation it looks like it will be 1.2-1.4m at it's highest point.
It's a 27m wall and the majority of it will be below 1 metre.
I rang our council and they said we need to get an engineering report done and council approval.
We can download the council approval form but how do we go about the engineering report?
Is it expensive?
Or are there ways we can avoid the report as it's only 20-40cm?
Someone said we should just build up the lowest point with compacted soil and build the wall on that to reduce depth.
Or do a terraced retaining wall (but is more expensive and we lose some of our land).
Or just build the wall and cover up the extra depth with dirt (*******?).
We plan to use concrete sleepers.
Any advice would be very much appreciated as we hope to do it asap.
