The surface area of the future design is 1025 sq ft. My plans are to run Pebble Tech to the edge. The process from here will be the same as it would be for a new overflow feature. I agree, David's tolerances are spot on! Three days with an excavator mounted hammer (a skidsteer mounted hammer down in the hole may be better or just keep the excavator far enough from the edge or ....gulp), bolt cutters, acetylene torch a Bobcat and two 10 yard dumptrucks, Starbucks and Redbulls for all, and viola ready for anything.
