Is it ok to bury the old wooden retaining wall?

I want to redo my retaining wall at the back yard. The wall will have concrete footer 4"-8", CMU blocks and caps, rebars, drain, etc).

I got two quotes that are reasonable in cost, but involves leaving the old wooden retaining wall, build the new one in front of it, then cover the old wall with dirt.

The thrid quote involves removing the old retaining wall. But the quote is over three times the other two.

Is it ok to bury the old wooden retaining wall?

Everything turns to dirt eventually, it's not going to cause any issues if buried.

Just think of all those tree roots that are in the ground!

If the old wood wall is left in place eventually it will rot away. At some point way in the future there may be a low spot that needs to be filled in with dirt. Other than that I might have them remove the top pieces of wood from the old wall and bury it so you can mow right over it.

I was worried about it becoming a home ground for termites. I think I will remove just the top layer and burry the rest. Thanks for the info...

The odds are termites will get into it at some point. A lot depends on your location as some areas are worse than others for termites. The fact that the timbers were soaked in creosote makes the wood less attractive to termites.
