Thank you. My understanding is that the pier locations will be staked so we see if any major roots will be hit. We know that some roots will be in the way, so I agree with the plan to immediately expose these roots once hit, and smooth cut them to avoid ripping or pulling when the drilling takes place. Thick pieces of plywood will need to be used underneath this equipment from the pint of entry (5’ beyond the drip line to each pier location. We want to be present when this occurs. Also, I have to ask the question again, do we know for sure that a two-man auger method is not possible? Slade Strickland Director of Parks and Recreation Town of Addison P.O.
