History
On June 16, 1970, the residents of a trailer court owned by Delbert Johnson 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.
