The city is about 14 miles (23 km) south of downtown San Diego. It's also only 5 miles (8 km) northwest of downtown Tijuana, Mexico. Imperial Beach is the southernmost city in California. It's also the most southwesterly city in the continental United States.

History of Imperial Beach

Santiago E. Argüello
Rancho Melijo, which included all of modern-day Imperial Beach, was given to Californio rancher Santiago E. Argüello in 1833.

Imperial Beach is on the traditional land of the Kumeyaay people. They had a village here called Alyshuwii. The city was founded in June 1887. It got its name from Imperial County, California, a desert area about 100 miles (160 km) to the east.

Farmers and landowners from the Imperial Valley came here in the late 1880s. They were looking for cooler weather during the hot summer months. In March 1887, over 2,000 workers came to nearby Coronado, California. They were building the Hotel del Coronado, which was the biggest resort in the world at that time. Many of these workers stayed in Imperial Beach. Some even made it their permanent home.

The city officially became a city in 1956. It started with its own fire department and police. Later, the San Diego County Sheriff's Department took over policing services.

Imperial Beach has worked to become more welcoming to visitors. In 2004, the city started a plan to improve its main streets. These improvements included areas along Palm Avenue and Seacoast Drive. In December 2013, a new hotel called Pier South Resort was finished. It has 78 rooms, a restaurant, and a spa.

Environment and Water Quality

Imperial Beach is at the end of the Tijuana River watershed. This means that anything that happens upriver can affect the city. Sometimes, the beaches in Imperial Beach have to close. This can happen because of pollution or spills that affect the water quality. For example, beaches have been closed since December 8, 2021.

The water quality has been a concern due to issues with wastewater flowing into the Pacific Ocean. This has caused problems for local businesses and can affect people's health. The city and other groups are working to improve the water quality and keep the beaches clean and safe.
