Break down 6" pump in MH for bypass and roll all hoses up break down wellpoint pump and points. Rain at 2pm.
Pumped out perimeter of #s-100, back-filled and compacted to within 3' of grade so contractor can cut walls tomorrow. Re-connected existing 4" underdrain to new box culvert and sealed. Shut down and removed wellpoint system for return tomorrow. Removed 6" pump from box culvert. Helped pond contractor set up 8" dewatering pump.

Met with Larry on site about debris from pond excavation, 6" backflow relocation and grade issue at #s-100 in relation to existing curb and driveway to parking area for civic center. Also discussed options for driveway modification with John and Butch from city. They liked my idea and will let me know tomorrow.
