In order to access our backyard for our pool construction, we would need to temporarily take down the fence between our yard and our neighbor's yard. They are not fans of the pool idea in and of itself, but agreed to this back in July. We provided them a document outlining what we'd assume responsibility for (fencing, irrigation, sod) but our big miss was not getting their agreement in writing... 
The project is already underway; we've paid our BYOP fee, have HOA approval, getting close to things beginning. Today they called to let us know they wanted to talk about the pool and long story short, informed my husband that they decided they no longer will allow us to remove the fence between our properties nor can their yard be damaged at all because of this project (magically "forgot" that they had even agreed in the first place). Without going into detail, nightmare situation.
We are working with our BYOP guy as well as waiting to hear back from the excavator in terms of how they'll get into our backyard to do the dig. We have 5'4" to work with inside the fence in question, and the other side of the house really isn't feasible as our AC unit + existing patio are on that side. Has anyone ran into this as we are bound and determined to figure out how to make this work now with this major wrench being thrown into our plans. FWIW, we are in Austin, working with BYOP on an IG pool and anticipate there being plenty of rock... Thanks in advance for any ideas/suggestions!
