What's New

House Bill 2800

Clackamas County opposes House Bill 2800: the Board of County Commissioners unanimously opposes HB 2800, which proposes a change in the governance of the Tri-City Service District. The Tri-City Service District was formed in 1980 by a vote of the public, who agreed to the County Commission serving as the District's governing body. Any change to the governance structure of the Tri-City Service District should be decided upon by a vote of the public in each of the cities, rather than be mandated by the State Legislature. The Board of County Commissioners recognizes that rate increases are one of the driving factors behind the bill's introduction and notes that these increases are necessary to help pay for capital improvements to the Tri-City plant, stemming in large part from growth within the District. A change to the District's governance will not change the fact that there is a need for capital improvements to avoid violations to the Clean Water Act, which protects public health and environmental quality.

Clackamas County hopes to continue the positive 35-year relationship and service with our partners Gladstone, Oregon City, West Linn, and the region. We believe we can reach agreement on these issues without legislative intervention. We urge a "no" vote if HB 2800 is considered.
