After browsing through Julie’s pool build I was intrigued by the concept of an irrigated lot. Where I’m originally from (Miami) an irrigated lot would be called storm surge, here in Atlanta, it would be a flash flood. The concept was quite foreign to me; there is a blurb in the link below if you are so inclined as I was. Interesting.

Without an option for flooding your yard, I suspect sprinkling city water would be the only other option?
