Johnson City

History

On June 16, 1970, the residents of a trailer court owned by Delbert Johnson (1909–1986) voted 49-to-10 to incorporate. Johnson had started the development in 1959, and in 1968 was unsuccessful in having the area annexed to Gladstone. The 55th Oregon Legislative Assembly in 1969 established a boundary review board to prevent an increase in small incorporated cities, but proponents of Johnson City's incorporation had filed for an election before the law took effect. The community is also known as Johnson Mobile Estates. Johnson City residents are not eligible to participate in the Clackamas County library system (LINCC), or any of its county partners. They are also not eligible for North Clackamas Parks and Recreation (NCPRD) programs, which includes Meals on Wheels. In an effort to join LINCC, the Johnson City Tenant Collective (JCTC) put Measure 3–585 on the 2022 November General Election ballot. It did not pass, and there is an open investigation against the owner of Johnson Mobile Estates for possible voter intimidation.
