Excavation to prepare for timber lagging wall
 
The clearing, grubbing and tree removal has been completed along the harbor access road. Excavation of the hillside has begun this week to prepare the slope for the timber lagging wall. Pile layout and installation will follow the completion of the excavation. After the piles are installed crews will begin placing the timber lagging between the piles. The completed retaining wall will be permanent and will provide the necessary shoring of the hillside for the multi-use trail.
