History of Mabton
Settlement in the Mabton area began around 1884, which was approximately five years before Washington became a state in 1889. The town grew out of a Northern Pacific Railway stop where the company had built a water tower.
In 1892, Sam P. Flower built a store and warehouse that was followed by several stores, a hotel, railroad depot and schoolhouse. The Mabton Townsite Company made their first plat for development in 1902 and Mabton incorporated on November 7, 1905.
The current city limits constitute an area of approximately 525 acres with an Urban Growth Area (UGA) of 578 acres. The population estimate for 2015 is 2,500 people.
