Document Description
The purpose of this project is to prepare the harbor for arrival of the ship M/V Delta Mariner, in support of delivery of the Delta IV rocket to Vandenberg Air Force Base.
The project consists of maintenance dredging the harbor at Vandenberg Air Force Base to its previously dredged depth of 12 feet MLLW. Dredging will occur as necessary to maintain depth for boats for approximately 16 years. Dredging may be required annually, and possibly twice in some years, depending on delivery schedule and sediment circulation patterns. If performed annually, predicted sediment volumes will be 1,500 to 5,000 cubic yards per dredging event. A bucket dredge mounted to a crane on the edge of the dock to be drained. Once drained, sediments will be transported by truck to Pt. Pedernales, where they will be used to back-fill an old borrow pit. Kelp mitigation will involve placing approximately 150 one-ton boulders into a sandy area between the break water and the mooring dolphins using a barge-mounted crane.
