After removing the pool (alas, no photos of the bulldozers), we let it sit for a while to see if the dirt would settle anymore. It stayed level. In November 2007 we had all new irrigation, large raised planters and a mulched orchard area installed. A line for container pots was also installed.
We had various problems with the irrigation but the installers have worked with us and I think it is all working as planned now. I worked with a local company that focues on sustainable landscaping.
