A big port is by the sea. 

The Port of Los Angeles is a big place by the sea. 


The Port of Los Angeles is a very busy seaport. 

Long ago, the bay was just a shallow mudflat. It was too soft for big docks. In 1871, Phineas Banning helped fix this. He dredged the channel. Dredging means digging out the bottom of the water. This made the water deep enough for ships.
Today, the port moves a lot of goods. It is the busiest port in the United States for containers. Containers are large metal boxes used to carry goods. Many items come from China, Japan, and Vietnam. The port brings in furniture, clothes, and electronics. 
Ships also bring pollution to the air. The port works to fix this. They use a Clean Air Action Program. This plan helps reduce smoke from ships and trucks. The port even gives power to ships while they dock. This helps keep the air cleaner for people.
The Port of Los Angeles is a huge seaport in San Pedro Bay. 

Moving goods through the port follows a specific way it works. Huge ships arrive at the docks to drop off cargo. Most of this cargo is kept in containers, which are large metal boxes. The port has 82 container cranes to lift these boxes. 
In the past, the bay was very different. It was once a shallow mudflat. The ground was too soft to build any docks. In 1542, Juan Rodriquez Cabrillo found the area and called it the "Bay of Smokes." Later, Phineas Banning helped make the port better. In 1871, he dredged the channel to make it deeper. Dredging is the way people dig out the bottom of the water. This allowed ships to reach the shore more easily.
History shows how much the port has grown over time. In the 1920s, it became busier than San Francisco. During World War II, more than 90,000 people worked there to build ships. 
Working at a large port involves many different jobs. Special pilots meet ships to help them steer through the busy water. 
The Port of Los Angeles is a massive maritime gateway located in San Pedro Bay. 

Moving goods through such a large facility requires a complex mechanical process. The port utilizes 25 cargo terminals and 82 container cranes to manage its workload. 
To keep large ships safe, the port relies on specialized maritime infrastructure. One critical component is the breakwater, a heavy structure built to protect the harbor from waves. In the early 1930s, a massive expansion included building an outer breakwater three miles out at sea. This structure is over two miles in length. An inner breakwater was also constructed off Terminal Island to create calm docks. These improvements allowed the harbor to host sailing events during the 1932 Summer Olympics. Today, the port even uses pilots to guide ships. These pilots have specialized knowledge of the congested waterways in San Pedro Bay.
The history of the area began with the discovery of the "Bay of Smokes" in 1542 by Juan Rodriquez Cabrillo. Originally, the bay was a shallow mudflat that was too soft for wharves. Ships had to anchor far out or beach themselves on the sticky ground. Phineas Banning changed this in 1871 by dredging the channel to Wilmington. Dredging is the process of digging out the bottom of a waterway to make it deeper. Banning also built the first railroad in the area in 1868. Following his death in 1885, his sons continued to promote the port's growth.
Growth accelerated through various political and industrial shifts. In 1897, a commission led by Rear Admiral John C. Walker endorsed San Pedro after a period known as the Free Harbor Fight. This led to federal support and the construction of breakwaters starting in 1899. By the 1920s, the port had surpassed San Francisco as the busiest seaport on the West Coast. During World War II, the port became a center for shipbuilding, employing over 90,000 people. 
The economic significance of the port is reflected in its massive trade numbers. In 2019, the port moved 8.8 million TEU, which refers to the volume of containers. This makes it the busiest port in the United States by container volume. In that same year, the port's top trading partners were China and Hong Kong, Japan, and Vietnam. The most imported goods included furniture, automobile parts, apparel, and electronics. 
Modern port operations must also address environmental challenges. Large ships and diesel trucks emit nitrogen oxides and particulate matter. These pollutants contribute to smog in Southern California. To combat this, the port implemented the Clean Air Action Program (CAAP) in 2002. This program uses cleaner-burning equipment to reduce harmful emissions. The port also installed Alternative Maritime Power (AMP) berths in 2004. These allow ships to plug into grid power instead of running their engines while docked.
