In my backyard there is a 20' x 20' sandbox on a slight incline (0' to 1.5') with an approximate volume of 300 cubic feet (11 cubic yards).
The sandbox served as a foundation for an above-ground salt water swimming pool for years (perhaps decades).
I want to remove the sandbox from my yard.
I have put together 100 sandbags, but I have no use for them and no one in the area seems interested in them. As well, for all that work, the sand that went into these sandbags hardly made a dent in the sandbox.
When digging down, it's just the top level that is sand. Beneath the sand is a fine gravel. I don't know the specific type of sand; it is similar to the sand found at the beach.
Is spreading the sand in the yard an option? Would covering in soil and grass (sod or seed) work?
