History

Umatilla County was created on September 27, 1862, out of a portion of Wasco County. Adjustments were made to the county's boundaries following the creation of Grant, Morrow, Union, and Wallowa Counties. This legislative act also designated Marshall Station as the temporary county seat. An 1865 election selected Umatilla City, now known as Umatilla, as the county seat. With the development of wheat farming, population shifted to the north and east parts of the county, and a subsequent election in 1868 moved the county seat again to Pendleton.
The Umatilla Indian Reservation was established by the Treaty of Walla Walla in 1855. The Umatillas, Walla Wallas, and Cayuse tribes were resettled there, and is located immediately southeast of Pendleton.
EZ Wireless of Hermiston officially opened on February 4, 2004, one of the largest known Wi-Fi wide area networks in the United States, covering parts of Umatilla County, Morrow County and Benton County, Washington. Although created to facilitate communications among local police, firemen and EMT workers who immediately respond to possible accidents or terrorist attacks on the Umatilla Chemical Depot, where the U.S. Army maintained a national arsenal of nerve gas, the network can be accessed in some places by the public for free.

Economy

The gold rush of 1862 brought miners and stock raisers to the mountains and grasslands of Umatilla County. Another stimulus was the arrival of the railroad in 1881, opening the region to the development of dry-land wheat farming. Water for irrigation has been key to economic diversification and growth, most recently in the Hermiston area, where potatoes, onions, corn, and more than 200 other crops are grown commercially. Low-cost power through Umatilla Electric Cooperative and good freeway access are also driving growth in the Hermiston area, with amazon.com developing large data-center operations there, and major distribution facilities for Walmart, FedEx, UPS, and Meyer Distributing are all located in Hermiston.
The Greater Hermiston area, which encompasses the Hermiston, Umatilla, Stanfield, & Echo zip codes, and equates to a less than 10-minute commuting distance, has seen strong job growth since 2012. The Hermiston area added 2,930 jobs from 2012 to 2022, which equates to 91% of all net job growth in Umatilla County over that time. More recently, Greater Hermiston accounted for 114% of Umatilla County job gains from 2019 to 2022 as a result of 1,121 jobs added compared to net losses of 74 and 48 jobs in Pendleton and Milton-Freewater respectively.

Communities

Umatilla County is generally divided into three distinct economic and cultural areas, which are the West End, the Pendleton area, and the Milton-Freewater area. Although each of these communities shares some economic ties, the distance between each creates three very distinct communities. The West End includes the communities of Hermiston, Umatilla, Stanfield, and Echo. The Pendleton area includes Pendleton, Pilot Rock, Adams, and Athena. The Milton-Freewater area is largely tied to the Walla Walla, Washington area, and is considered a part of the Walla Walla Metropolitan Planning Organization. The similarities between the areas has created a long-standing rivalry, particularly between the West-End and the Pendleton-area, with regard to economic opportunity and public resources. The West End, led by Hermiston as its largest city, is now nearly twice the size of the Pendleton area, and is projected to be nearly three times the size of the Pendleton area by 2035.
