You should dig all the dirt that's piled up by the fence because the
moisture will rot the wood. THEN install the retaining boards (pressure
treated) next to the fence. I've got 120' of fence that's constructed
with 2x12's next to it to retain the dirt which is higher on my property
than the neighbors. It's been holding up well for more than 13 years.
The previous fences didn't last but a few years w/o PT wood and retainer.

Good afternoon!
Hi, I'm new here. Great site!
We are in the process of adding lots of dirt to level our 32'x26'
backyard.
It has taken months to get the dirt ready for seeding (new construction
had left all kinds of trash in soil).

My next problem is that my lot angles from 6" to 2' sloped on one side
of my neighbor. There is a fence which is supporting the dirt, but I
want to reinforce on my side. I was thinking of digging in and putting
2x10s the length of the fence and filling the dirt back.

Any suggestions?
PS...its a condo, so I am limited in what I can do ie using cement or
some more permanent fixes without board approval....
Thanks!
