Annexation process

The local jurisdiction initiates a boundary change, and should provide Metro with the following items for the final action packet:

  • Final approval from DOR or the "Notice to Taxing Districts"
  • Annexation Order, Ordinance or Resolution
  • A valid legal description of the annexation
  • A map clearly showing the current boundary (if available) and the proposed annexation area
  • Any additional pertinent documents including staff comments and findings (if available)
  • A check payable to Metro for the mapping and filing fee (see below)

Metro will map the annexation and make the appropriate notifications to the Secretary of State's Archives Division, the county elections supervisor, and the county assessor. Please note that an annexation is not in effect until filed with the Secretary of State (subject to ORS 222.180 and/or ORS 222.750).
