Originally a logging settlement, the area was first called "Federal Way" in 1929, when Federal Way School District #210 was created. The name derived from U.S. Route 99 (now State Route 99 or Pacific Highway South), completed that decade, which ran through the area on its way from Everett and Seattle to Tacoma. Federal Way High School was built, and about 20 years later, the name was adopted by the local Chamber of Commerce. The city was incorporated on February 28, 1990.
