i am going to try to fill in an L shaped pool ( 16ftx33ft,7ftx10ft) deep end is 10ft and the shallow end is 4ft. i found a calculator on the internet that found how many yards of fill dirt i would need and it came out to 170. i am not sure if it is correct, is it? if this is true i am in a heap of trouble, the pool is only aproachable by a skid loader due to trees, landscaping, and neighboring houses. what should my plan of attack be? i am doing this for a friend of the family, so i am trying to find the most inexpensive way to complete the project.
