Ratcliff Lake Recreation Area

Spillway Repair

Scope of Work

To provide all labor and materials to repair Ratcliff Lake Recreation Area dam spillway, construct the proposed dam access road and remove vegetation on the face of the dam.

Spillway repair will consist of constructing a new concrete spillway to the same general dimensions as the existing spillway including upstream and downstream cutoff walls. The existing spillway wing walls will also be replaced. The downstream chute of the spillway will be replaced as per drawings and specs.

Construction will consist of re-grading the chute and replacing the existing downstream chute with a chute consisting of grouted rip rap, articulated blocks or a combination of both. A gravel/perforated underdrain system will be constructed as part of this contract.

The proposed access road will be approximately 1200 feet long. The road location will be 30 – 50 feet from the toe of the dam. The road will be 12-feet wide constructed with flexible base material. A square pad at the end of the road is planned for a turnaround and staging area.

Vegetation removal consist of clearing and grubbing of all vegetation on the upstream and downstream face of the dam. Stump removal will be required on vegetation 4 inches in diameter and less.
