Greenfield (formerly, Clarke Colony) is a city in Monterey County, California, United States in the Salinas Valley, 33 miles (53 km) southeast of Salinas, at an elevation of 289 feet (88 m). The city was the fastest growing in the county during the 2000s: the population was 12,583 in 2000, increasing to 16,330 in the 2010 census. Its most well-known public event is the annual Harvest Festival. Greenfield is a member of the Association of Monterey Bay Area Governments.


John S. Clarke and other promoters laid out the town from 1902 to 1905 on part of the Rancho Arroyo Seco Mexican land grant, created by a subdivision of 4,000 acres (1,600 ha). The Clark Colony Water Company, which became the organization for water distribution, filled the city with water from the nearby Arroyo Seco AVA was formed in April 1905. The organized water canal system and ideal growing conditions attracted people of Danish, Swiss and other nationalities from surrounding areas to settle in Greenfield. Today, the Clark Colony Water Company still holds 1916 Prior Rights guaranteeing delivery to its members a certain amount of water from the Arroyo Seco River before any other agencies. In 1906, the district purchased a lot from Edward Greenfield along with two adjacent to the Arroyo Seco Development Company. Clark Colony evolved into Clark City and was eventually renamed Greenfield, in honor of Mr. Greenfield., after the United States Postal Service informed the City that there were too many "Clark Cities" in the state. Greenfield was recognized as a municipality by the State legislature and incorporated on January 7, 1947. Greenfield's first Mayor was Tom Rogers.

In recent years, the town has seen an influx of immigrants from the Mexican state of Oaxaca. Many Oaxacans speak indigenous languages not related to English or Spanish; as a result, they find communication with the large Spanish-speaking and smaller English-speaking population difficult. Probably the largest single bloc of such immigrants are speakers of the Copala Triqui language, who have fled from poverty and long-standing armed conflict in their native region.

Arts and culture

Greenfield holds an annual harvest festival each third Sunday of October.

A Northern Campus for the Yanks Air Museum of Chino, CA will be built in Greenfield on a 440 acres (1.8 km2) plot known as the "Hanson Ranch" purchased in 1994 by museum founders Charles and Judith Nichols. Ironically, in World War II the Hanson Ranch was the site of the Hanson Auxiliary Field. The new airstrip will use the original location and will see World War II aircraft landing there some 75 years later. This planned project will include a museum facility and the 4,250 feet (1,300 m) runway that will support both museum flight operations as well as serve the private aviation needs of both museum visitors and local aviators. The new museum facility is not intended to replace the existing facility in Chino, but to greatly expand the opportunities.

Greenfield is constructing the Tom Rogers Community Museum. Named after the first mayor of Greenfield, it will showcase the history of the city as far back as 1905.
