The MCR Regional Sediment Management Plan

The Mouth of the Columbia River Regional Sediment Management Plans (MCRRSMP) are the outcome of a multi-year, bi-state collaborative effort to manage dredged sediment placement at the mouth of the Columbia River in a beneficial way.  The plans are supported by the Lower Columbia Solutions Group (LCSG) and additional agencies, who have committed to working together in a collaborative manner for adaptive sediment management (see attached 2012 Declaration of Cooperation).  The Plans outline near-shore and beneficial use disposal sites along the Oregon and Washington coasts, which are monitored for biological and other impacts.

Based around an adaptive management framework, the MCRRSMPs are to some extent living documents that are constantly being adapted by new research and monitoring. Below are the 2011 and 2023 Regional Sediment Management Plans, as well as the associated Declaration of Cooperation signed by the stakeholders in support of the Plan in 2012. Documents and progress reports leading up to the development of this plan can be found on the main Regional Sediment Management Planning page.

The 2023 RSPM provides an updated vision and direction for an ongoing beneficial use program that builds on experiences and lessons learned through a series of demonstration placements of dredged materials from the MCR. Specifically, the Update:

• Reaffirms the program goals and elements identified in the 2011 RSMP.
• Identifies current management direction and structure.
• Identifies the focus for program activities in the near-term and intermediate futures.
• Summarizes scientific findings from research and monitoring conducted to date.
• Updates the program’s history and accomplishments.
• Reorganizes and expands the contents of the 2011 RSMP.
