Excavation of the pool site is done in accordance with the County or Township that you live in:
The site will need to be excavated larger than the actual pool size. Our standard is to excavate the site 4ft. larger all the way around the entire pool size. However, this may be More/Less than what your Township or County requires. There is No Uniform Code between Townships/Counties. You can get this information by contacting your local Township or County Zoning office.
