Evergreen Fountains, a senior living community in Spokane Valley, recently completed a more than $12 million expansion project to add a three-story living facility, cottages, a skywalk and an outdoor recreation park. Evergreen Fountains – co-owned by real estate developers Prokey and Greg Arger and Greg’s son, Gene – opened in 2008 with more than 106 independent, light-assisted and assisted-living apartments.
