 The idea gained popular support through the 1990s, however, partly in response to the passage of the Washington State Growth Management Act of 1990.Formation of an exploration committee in 1995 led to a successful public vote shortly thereafter, and the city formally incorporated on August 31, 1998, 97 years after its original founding.Following incorporation, the new government set about devising a local set of zoning codes and a downtown development plan with the intent of reviving and rebuilding the traditional core areas of the city.
