District Maps & Information


Redistricting Information

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.
