Mike, welcome to the forum!

Though I've never installed a FG pool, with any other type you need a couple of feet of 'overdig'. This allows you enough room to attach the pipes needed for plumbing the pool.

If you want a FG pool in your yard, call the local FG pros and see what they have to say

If you want a liner or 'crete' pool, I can assist you in your selection, and you'll get input on all 3 kinds from the nice folks here!

What you need to do is decide what kind of pool you want and what your budget is. (you could easily put up a AG pool on your basketball court )

I hope to hear back from you on this
