Retaining wall question.

Hello,

I am putting my first pool into my very small property. I intended to move for years so put it off but the market here is crazy, like $1mil for my 1500sqft house with postage stamp lot so sadly I’m not going anywhere.

I have researched this topic on here but it’s all regarding much bigger retaining walls.

The pool is planned for the rear corner of the lot. The back side being level with the neighbours property. The side has a small wall.
The whole yard was heavy stone bricks, which I have removed, and I put in a new fence and redid the small wall. The retaining wall for the bricks was pressure treated 6x6 butted up against 4x4 fence posts. This all held fine.

I redid the posts with 6x6s and the wall with 6x6, they go against the posts.
Anyways, I am looking at a 15’ above ground pool, and hoping to come close to this wall. I’ve read about surcharge and believe I should be ok. The max height of this wall is 12”, minimum height is about 8. I was planning on going 3 feet back, as the formula is twice height , but I figured I’d err on the side of caution. But as it isn’t a stone wall…..is this a concern? The pool will be dug in 6” at least I think making the height of the wall even less. I just really don’t want a surprise someday. Aka a collapsed pool.
I understand the wood wall requires replacement eventually and not a lifetime material. But if all in good condition, is this a concern?

Thank you!
 
Ideally you would have built a wall and put the on it. This way you would loose as little space as possible. Do you have the needed setbacks and is the fence the required height for a pool?

Hey Bill.

I can move away from the wall 3 or 4 feet if need be. I just want to know if that’s far enough to not have issues from the weight. The wall was not designed with a pool in mind, I just put back what was there. The pool idea came after.
The fence height is more then good for the pool. I could move the pool like 10 feet from the wall as well but am not sure the electrical cord will reach.
But that’s minor, I’m most concerned about the weight and close far away is safe.
 
I misunderstood, I was thinking you wanted to add a retaining wall on your side of the fence. I guess there is a one on the other side of the fence and the ground drops off.

The biggest factor is going to be what was put in place to manage water from building up behind the retaining wall. And how well is the wall set into the ground.

For piece of mind an engineer would be your best bet.
