Maps, data and research › Annexation and boundary changes
Metro provides boundary change filing and mapping services for the region’s cities and special districts; including fire, water, and park districts. Metro handles the statutorily required distribution of the final action packet on each boundary change.

The local jurisdiction initiates a boundary change, and should provide Metro with the following items for the final action packet:
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 199.461 and/or ORS 222.180 and/or ORS 222.750).
In addition to the items listed above, the Secretary of State's letter acknowledging receipt and filing is included in the final action packets which are posted here on Metro's website. Use the links on the right to download a packet.
