were all that was holding up the failed section of wall. (Boats
have been removed to safer locations, electric has been turned
off to the power pedestals and area has been cordoned off.)
Repairs to be, in multiple steps, not necessarily in below order.
1. Emergency/Safety Repairs, possibly installing more
timber piles north/waterward of C-Dock to help dock hold
wall somewhat up while final plans are determined.
2. Excavator/Back-Hoe will be needed to access
south/landward side ol'wall to remove pressure from
backside. Note the tiebacks to cap are in place, so the
failure appears to be in the tieback to deadman
