Question about landscaping around excavation

[gdog2004]

Hi guys. I had my 21' AGP installed. Its level and all but there was a 13" dropoff from high point to low point when excavating.
The excavator dug an additional 2 to 3 feet around the pool so its up to my townships code. So how exactly do I landscape this ? Do I fill it all in with plastic and rocks ? On one side the rocks will come about a foot up the pool wall. On the other side not so much. Is this normal ?

Does your township have any guidelines as to what you can do to it? If not then I'd backfill it and plant some small plants or dress it however you prefer.
