The procedures in this User Manual replace guidance in all previous versions of the DMMP User Manual. The updates apply to all projects in Puget Sound, on the Washington Coast, the north side of the Columbia River, and all other water bodies within the State of Washington.
This edition of the DMMP User Manual reflects technical and policy updates that have occurred through the sediment management annual review meeting process and public workshops. It is considered to be a living document and is revised periodically as needed to reflect changes made through the public review process.
