TriMet buses and commuter rail also serve [[Wilsonville, Oregon]], which is outside the TriMet district, in order to provide connections to transit services operated by [[South Metro Area Regional Transit|SMART]] in that city.

A state law that went into effect on October 1, 1987, enabled communities with a population of less than 10,000 to petition to leave the TriMet district. A petition, which needed to be signed by at least 15&nbsp;percent of registered voters in the affected area, must demonstrate that a community is not receiving adequate service and that TriMet's payroll tax is adversely affecting business activity for the withdrawal from the transit district to be approved.<ref>{{Cite news |last=Boyd |first=Malcolm |date=September 30, 1987 |title=Sandy City Council to ponder secession from Tri-Met |url=https://infoweb.newsbank.com/apps/news/document-view?p=EANX-NB&docref=image/v2%3A11A73E5827618330%40EANX-NB-13298BD05455A553%402447069-1328D7C5DF93D6BD%4028-1328D7C5DF93D6BD%40 |url-access=registration |url-status=live |archive-url=https://web.archive.org/web/20230915040324/https://infoweb.newsbank.com/apps/news/user/login?destination=document-view%3Fp%3DEANX-NB%26docref%3Dimage/v2%253A11A73E5827618330%2540EANX-NB-13298BD05455A553%25402447069-1328D7C5DF93D6BD%254028-1328D7C5DF93D6BD%2540 |archive-date=September 15, 2023 |access-date=April 9, 2022 |work=The Oregonian |page=B7 |via=NewsBank}}</ref> The first three areas to make use of the law and withdraw from the TriMet district, effective January 1, 1989, were [[Damascus, Oregon|Damascus]], [[Molalla, Oregon|Molalla]], and [[Wilsonville, Oregon|Wilsonville]].<ref name="withdrawal-approved-1988">Federman, Stan (December 1, 1988).
