Background: Benton County Talks Trash
Following a pair of conflicting 2021 decisions from its appointed solid waste and land use
bodies, and in response to substantial community concern over a proposed landfill expansion,
the Board of County Commissioners asked Oregon Consensus to help understand the situation
and identify, if possible, a constructive path forward on solid waste and disposal, including at
the Coffin Butte Landfill. Following the Board’s direction, a third-party facilitation team helped
convene a community member-based Workgroup representing a diverse balance of
perspectives and established a Charter and Bylaws to guide the work.
Dubbed “Benton County Talks Trash,” the workgroup was tasked with building “common
understandings” around key topics and outlining the table of contents for a modern, long-term
Sustainable Materials Management Plan. To complete these tasks, the workgroup established
five subcommittees to dive into specific topic areas and then report back:
- Developing a Sustainable Materials Management Plan (SMMP)
- Estimating the Landfill Size, Capacity and Longevity
- Clarifying legal issues and reviewing land use law
- Determining the status of past land use Conditions of Approval
- Improving Community Education and Outreach
