501 Grant Ave Sunnyside, WA Built in 1930, the Sunnyside Water Department building was home to the city's two water wells (since capped but still in the basement) as well as the vehicle maintenance department. Over the years as new facilities were developed, the old building was boarded up and used for storage. In 2015 the Port of Sunnyside, working with Co Dinn Cellars, the City of Sunnyside and Yakima County came up with a plan to convert the classic Deco-inspired building into a modern winery and tasting room. We did keep the large overhead crane in the tasting bar!
