We are currently having a pool built in Gilbert Az and we have run into an issue and I'm not sure how to proceed. Its an inground shotcrete pool and they just finished pouring the deck two days ago. I noticed that toward the back of the deck the ground is actually higher than the deck! My yard slopes from back to front slightly, just enough for storm water to drain to the front of the house. I brought this to the attention of the construction superintendent and he said they noticed that once the deck was complete. He is telling me that it will be fine as long as I slope the ground away from the deck, creating a "V" shaped trench that will allow water to drain. He also suggested we could build a retaining wall!! I have no idea whether either of these suggestions are going to actually work and I am concerned that they did not take into account the slope of my yard and are putting the responsibility on me to make it work . Any advice would be greatly appreciated.
