Annexation Information

A petitioner needs to complete the Annexation Packet for annexing property into a service district. 

The Annexation Packets are available below and also by calling 503-742-4567. Once you have completed the Annexation Packet return it to our office. The Annexation Packet is then filed with Clackamas County Elections. The Elections office requires two checks to accompany boundary change applications, one to Clackamas County for the application fee and the second to Metro for the mapping fee.

Tri-City Service District (TCSD)

The TCSD primarily provides regional collection and wholesale sanitary sewer treatment services. The TCSD boundaries coincide with those of the partner cities of Gladstone, Oregon City and West Linn. Property owners must first annex to one of the member cities, then to TCSD. Only those parcels in one or another of the cities can receive sanitary sewer service.
