About this file
This is a set of planning layout drawings for the Maintenance Dredging 2025 Oregon and Washington Clamshell project, solicitation number W9127N25BA002, issued by the US Army Corps of Engineers Portland District. The comprehensive document contains 20 detailed drawing sheets covering multiple river locations including Port Orford, Charleston, Baker Bay, Chinook, Longview Turning Basin, Old Mouth Cowlitz, Kalama Anchorage, and Vancouver Lower Anchorage. Each drawing provides specific surveying data, dredging area boundaries, placement site details, required dredging depths, and geographical coordinates, with survey dates ranging from January to April 2025.
The project involves maintenance dredging at various river locations along the Oregon and Washington coastline, with precise specifications for dredging depths, placement sites, and material dispersal. Placement sites have specific maximum capacity limits, such as 100,000 cubic yards at 2 feet deposition for Baker Bay and Chinook sites, and restrictions on material distribution during flood and slack tides. The project includes multiple dredging areas with varying required depths, ranging from 10 to 45 feet, and uses clamshell dredging techniques. The award date is listed as 04-APR-2025, with individual site survey dates varying, and the project is managed by key personnel including Patrick L. Duyck, Daniel F. Howard, and Colonel Larry Caswell, Jr.
