Author Walt Morey owned an estate in Wilsonville. After his death in 1992, his widow sold the property to a developer, and the housing development built on that property, Morey's Landing, bears his name. The children's section of the Wilsonville Public Library is dedicated to his memory..

In 1995, Dammasch State Hospital was closed by the state of Oregon, and the site was then proposed as a location for what became the Coffee Creek Correctional Facility, which opened in 2001. In protest of the construction of the prison, specifically the effect on property values, Larry Eaton began erecting school buses on his property. The former grounds of the state hospital are, as of 2008, under development as Villebois, a primarily residential complex.
