Redistricting Information

After the 2010 Census, 2011 and 2012 were transitional years for redistricting of political boundaries. Political boundaries that effect voters in Multnomah County include US Congress, State Senate, State House, Metro Council, Multnomah County Commissioners, PCC board, MHCC board, ESD boards, Rockwood and Interlachen PUD boards. 

All districts have completed the redistricting process and that information is available on our website.
