The town of West Union stood between today’s Edgewood Road and Raymundo Drive in Woodside. It was originally developed by the employees of two lumber mills on West Union Creek established by Willard Whipple. Farming supplemented the lumber work, and other businesses such as a saloon and market quickly came into existence. When the timber ran out, two wineries began planting grapes and were successful. A school house stood where the power substation is currently.
