The project is limited to excavation of approximately 2,850 cy (cubic yards) of accumulated sediment/material from the harbor entrance by means of two long-reach excavators. One excavator will be located along the upland property of the harbor (adjacent to the boathouse) and a second excavator will be barge mounted. The two excavators will work in tandem to dredge the harbor to the approved maintenance
depth. As the material is being excavated, it will be deposited onto hoppers and low-level conveyors located on the lawn area adjacent to the boathouse to move the material approximately 250 feet to be deposited into lined and sealed trucks. The dredged material will be transported outside the Lake Tahoe basin to a legal point of disposal. To minimize turbidity, all dredging will be done behind heavy-duty turbidity curtains, which will remain until the turbidity is reduced to acceptable levels. The 30-inch-wide conveyor belt to move the dredged material will be above a continuous, 12-foot-wide, Mirafil woven filter fabric bordered by staked fiber rolls. The filter fabric will capture any material spilled from the conveyor belts so personnel can deposit it into the trucks for transport.
