The area was considered desirable by the Union Pacific Railroad because of the many stone quarries in the area near the town of Stout (now flooded by Horsetooth Reservoir). The influx of railroad workers to work the quarries prompted Flowers to open a general store, saloon, barber shop, and post office. In 1880 he built a one-story sandstone structure to house his business. The Bellvue Post Office opened in the building on June 24, 1884. The building served as the local general store and post office up through the middle 20th century, when it became the meeting house of Cache la Poudre Grange, Chapter 456 of the Colorado State grange, a designation for which it is now commonly known.
