Pre-fab urban boomtown just north of Tacoma, WA
, though desperately trying to identify itself as part of the Seattle
metro area, and the sixth largest city in Washington (population nearly 70,000).
Before incorporation as a city in 1990, Federal Way was the name for a loosely defined area between I-5 and Puget Sound and south of Sea-Tac Airport. Aside from scattered houses and a few developments, the only built-up area was that along Pacific Highway, state route 99. The area and city got its name from the establishment of the interstate so many years ago.
As a city, Federal Way has at least one of almost everything: amusement park, shopping mall, one of nearly each local restaurant chain, state park, major highway, major industrial company (Weyerhauser), etc. As a result, along with a glut of strip malls and apartment complexes, Federal Way has no actual identity to speak of -- a sort of urban suburbia.
Populated largely in the 90s by people attracted to Seattle and Redmond's tech-related boom, and DOA startups such as Freeinternet.com, it's standard of living has fallen considerably since the rather disastrous bursting of that bubble.
