I was not able to take pictures of everything but here are the main pictures to give you an idea:
We used lots of fill. This is the first delivery of dirt which was dumped in the front yard.
The first layer of fill at the bottom was actually gravel. That covered the holes in the bottom of the pool and dirt fill was dumped on top of that.
More fill,
...keep filling. Needless to say the Bobcat bulldozer tore up the yard. A lot more than I anticipated. It also broke underground sprinkler piping and even cracked some of the driveway it was so heavy.
After finally getting filled in, the dirt was raked out and leveled before inspection. We passed inspection so now there is no more pool to worry about.
We wanted to be able to enjoy our backyard so we replaced the pool with a wood deck which has ample space for us to use the grill or walk around on. Ultimately I would like another slab but I want to give the ground time to settle. I expect to see the ground dip somewhat where the pool used to be as the fill dirt settles. Putting a concrete slab over the filled in pool would not have been a good idea since the ground had not settled yet.
