History of Imperial

The city of Imperial was started by the Imperial Land Company. George Chaffey gave the city its name. Imperial got its first post office in 1901. The city officially became a city (was incorporated) in 1904. Allison Peck was the first mayor of Imperial.

The town was planned in 1902 for homes and businesses. Its first buildings included a printing press, a drug store, and a church. Imperial was also home to the first school and the first Chamber of Commerce in the valley.

Imperial was the first city in the valley to become officially incorporated on July 12, 1904. It was first thought to become the county seat, which is like the main city for the county. But in 1907, El Centro became the county seat instead.

Over the years, Imperial became home to important places. These include the Imperial Irrigation District, the California Mid-Winter Fair, and the Imperial County airport. Many businesses also opened in the city. Imperial was hit by strong earthquakes in 1916 and 1940. In 1979, another earthquake damaged many old buildings downtown, including City Hall. It took several years for the city to rebuild its business area.

In June 2014, a McDonnell Douglas AV-8B Harrier II jet from Marine Corps Air Station Yuma crashed in a neighborhood. The pilot was safe, and no one on the ground was hurt.

Geography and Landscape

Imperial covers about 5.9 square miles (15.3 square kilometers) of land. It is located in the Imperial Valley, which is part of the Colorado Desert. The city is actually 59.5 feet (18.14 meters) below sea level.

Farmers in the area get water from canals. These canals bring water from the nearby Colorado River. The Salton Sea was formed in 1905 after a flood from the Colorado River.

The land in this region is always changing. This is because it is where two large tectonic plates meet. These plates are slowly moving apart and sliding past each other. This movement causes earthquakes in the area. It also makes the land slowly sink over time.

Climate and Weather

Imperial has a very hot desert climate. Summers are long and extremely hot. Winters are mild and pleasant. Imperial gets only about 3 inches (7.6 cm) of rain each year. December is usually the wettest month.

From July to September, the North American Monsoon brings more humidity. Sometimes, the weather can feel like tropical areas. This can lead to daily thunderstorms with hail, heavy rain, lightning, and dust storms called Haboobs.

During hurricane season, storms from the Pacific Ocean sometimes move up the Baja California Peninsula. These storms can bring heavy rain to the desert. This can cause flash floods. In winter, rain showers come from occasional storms. These storms can bring cold temperatures and mountain snowfall to nearby areas. Snow almost never falls in Imperial. A tiny bit fell in 1932, and sleet mixed with hail fell briefly in 1967.

On average, temperatures drop below freezing about 3.7 days a year. In December, the coldest month, the average high is 67.5°F (19.7°C). The average low is 42.3°F (5.7°C). In August, the warmest month, the average high is 104.5°F (40.3°C). The average low is 78.4°F (25.8°C).
