Vineyard sits on the eastern shore of Utah Lake, beneath the Wasatch Mountains, and has become the fastest-growing suburb in America. The city was population 139 at the 2010 census and reached 13,000 by 2020. The driver is the massive redevelopment of the former Geneva Steel site, one of the nation's largest mills until it closed in the early 2000s. A 700-acre project called Utah City is transforming the lakeshore into a mixed-use urban center with residential, commercial, and recreation. Utah Valley University bought 125 acres to build a west campus. The Huntsman Cancer Center is locating a new Utah County facility on the UVU site. For the roughly 2,700 Medicare residents in this young, growing city, that means working with a very different community character than traditional Utah communities.
