We have an 8-ft diameter, 3 ft deep, concrete ornamental pond in our front yard. It's dirty, stagnant, attracts mosquitoes, and is dangerously alluring to our toddler. I want to get rid of it, but hiring a contractcor to rip out the concrete is expensive. Can I just fill it myself? If so,
1) Do I need to punch holes in the concrete for drainage?
2) Do I use gravel to fill it partway and then cover with topsoil? How much of each? Or is it beeter to use all clean soil fill?
3) I'd like to plant grass over it when I'm done. How do I deal with settling? Rip out the grass and put new soil down every time?
