Sand Separation Project
Project Description:
This is primarily a maintenance dredging project for the South Entrance Channel to Marina del Rey Harbor. CJW is the contractor that was selected they will dredge the sediment and pump the material to parking lot 3 on Dockweiler Beach. CJW will remove and separate approximately 50,000 cubic meters of material over the next few months. Screens and Hydrocyclones will be used to separate the sand from the fine grained material. As the material is processed the products will be debris, sand, fine grained material such as silts and clays and water. The sand will be spread on the adjacent beach filling in the eroded area after it has been determined to be acceptable for beach placement. The debris along with the fine grained material will need to be disposed of in an acceptable manner, methods could include; placement in a Port fill, upland placement in an acceptable landfill or placed in the CAD Site and covered with clean material. All water that is used in the removal and processing of the sediment will need to be treated before it is allowed to return to open water.
