Westmorland (formerly, Westmoreland) is a city in Imperial County, California. Westmorland is located 8.5 miles (14 km) southwest of Calipatria. The population was 2,225 at the 2010 census, up from 2,131 in 2000. It is part of the El Centro Metropolitan Area.
Westmorland is on State Route 86, which was upgraded to a new six-lane highway to reduce its infamous auto accident and fatality risk, while it connects with Brawley, El Centro and Mexicali, Baja California, Mexico.
The post office, originally called Westmoreland, opened in 1909; it closed in 1912 and re-opened in 1919. It was renamed to Westmorland in 1936. Westmorland incorporated in 1934.
From the 1920s through the 1950s Westmorland was the site of illegal gaming establishments and many brothels, but these were later destroyed in an attempt to improve the town's image.[when?]
Westmorland has dealt with the image of high poverty rates, and prior to the 1990s North American Free Trade Agreement (NAFTA) economic boom, a nearly dormant farm food shipping industry.
