Adaptive Management of Pilot Projects in Washington (2020)

The Lower Columbia Solutions Group (LCSG) conducted a January 14, 2020 workshop to explore the opportunities and constraints to federal funding for nearshore and on-shore beneficial use projects for the disposal of dredged materials from the Mouth of the Columbia River, as well as to develop plans for 2020/2021 beneficial use projects in the nearshore and on-shore along the Oregon and Washington coasts.   The workshop was organized around four key objectives:

  1. Assuming that we have progressed from a series of pilot projects to a routine disposal and monitoring program at the South Jetty Site, what is the threshold for no harm in terms of disposal volume? Are we comfortable that the site’s re-certification process scheduled for 2022 will provide the appropriate process and timing for assessing the need for adaptive management of disposal and monitoring at this site?
  2. What can we conclude about the North Head Site from the two-year pilot project? What are the next steps for this site?
  3. Based on what have we learned today about RSM authorities and funding opportunities, what are the strategies and next steps for establishing a sustainable beneficial use program at MCR?
  4. What is the overall strategy and the next steps for implementing onshore placement at Benson Beach?
