Known as “The City of Open Spaces and Friendly Faces”, Piedmont has ranked among the fastest growing cities in Oklahoma, but it wasn’t always that way. Although Piedmont was incorporated before Oklahoma became a state, its population was less than 300 until the 1950’s. Piedmont is in the Central Plains eco-region, which is a transition area between the once prairie (now winter wheat-growing) region to the west and the forested low mountains to the east.
