Jim,
Sent too soon. I want to also thank your for bringing the space around the back of the pool to my attention. There will be a 12" planter next to the retaining wall and then the 12" coping all around the pool. However, I am now gathering, as you noted, that 12" coping up against the planter is likely not enough room for ease of walking or the pool guy to clean. I will talk to pool builder as well as our landscaper (who work in conjunction) to be sure there is enough space between the planter and the coping. I am thinking we will need another 1/2-1' more and could add our artificial grass between planter and coping. Although this will push to pool closer into the yard, logic and practicality wins. The shortest distance between the pool and decking is 6', we were trying to not lose another foot yet we may need to shift the extra foot it from the front to the back of the pool. I just missed this one and no one but you caught it! The pool builder said when he lays it out in string we can make any adjustments. Now I have one! Without seeing plants there and only dirt no one may have caught this. From your experience, how many feet from waters edge do you think we need before hitting a plant? ( 1', 1.5', 2'?) If the yard space was not tight it would not be an issue. Thanks again, Ellen M
