In page Richland, Washington:

"

In 1904–1905, W.R. Amon and his son Howard purchased 2,300 acres (9 km2) and proposed a town site on the north bank of the Yakima River. Postal authorities approved the designation of this town site as Richland in 1905, naming it for Nelson Rich,[1] a state legislator and land developer. In 1906, the town was registered at the Benton County Courthouse. It was incorporated on April 28, 1910, as a fourth-class city.[citation needed]
