Biohazard and Crime Scene Remediation in Johnson City, OR

Johnson City is a city in Clackamas County, Oregon, that had a population of 539 as of the 2020 census, living in 275 households.

Because of its tiny area of just 0.069 square miles, Johnson City's population density is over 8,000 persons per square mile, making it the most densely populated city in Oregon.

Johnson City was incorporated on June 16, 1970, when residents of a trailer court owned by Delbert Johnson voted 49 to 10 to incorporate, after Johnson had started the development in 1959 and failed in 1968 to have the area annexed to Gladstone.

The community is also known as Johnson Mobile Estates, and it sits at an elevation of 112 feet near Gladstone in Clackamas County.

Johnson City's incorporation vote came just ahead of a 1969 law by the 55th Oregon Legislative Assembly that created a boundary review board to prevent an increase in small incorporated cities, since proponents had filed for the election before the law took effect.

Johnson City residents are not eligible to participate in the Clackamas County library system, known as LINCC, or in North Clackamas Parks and Recreation programs, which include Meals on Wheels.

In an effort to join the library system, the Johnson City Tenant Collective put Measure 3-585 on the November 2022 ballot, but it did not pass, and there is an open investigation against the owner of Johnson Mobile Estates for possible voter intimidation.

Johnson City is listed with ZIP code 97267 and area codes 503 and 971, and the city is entirely urban, with 100 percent of its residents living in urban areas as of the 2020 census.
