Surfside (or Surfside Colony) is a small gated community with three rows of houses, lettered A, B, and C. Surfside is part of the city of Seal Beach, California and is located on the west side of Pacific Coast Highway, southwest of the Naval Weapons Station Seal Beach between the station and the Huntington Beach community of Sunset Beach. It is also near the Huntington Beach community of Huntington Harbour. The southern entrance to the Surfside Colony is easy to spot by the water tower (which was built into a house) that can be seen from Pacific Coast Highway.
The Surfside Colony is served by the Surfside Colony Community Services Tax District and the Surfside Colony Storm Water Protection Tax District. Lifeguard services are provided by the city of Seal Beach.
Surfside Colony was begun in 1929 as an oceanside resort community. It was incorporated with the state of California in 1930. There were originally plans to develop both sides of Pacific Coast Highway (with D and E rows of houses on the east side), but these plans never materialized. A tunnel, which still exists though it is inaccessible, was built under Pacific Coast Highway to facilitate easy transit back and forth.
During World War II, the U.S. Navy developed the area to the north of Surfside as an ammunition depot. A large jetty and channel were built to allow ships to dock. This development altered Surfside and its beachfront significantly. Changes in wave patterns and resulting erosion have continued to plague the community since then. Every few years, the U.S. Army Corps of Engineers must work to replenish and rebuild the beach, dredging and refilling with millions of cubic yards of sand.
On July 4, 2008, a small plane pulling an advertising banner lost power and was forced to land in the water just off the shore of Surfside. The pilot suffered only minor injuries, and no one in the water was injured.
The colony of Surfside is located adjacent to the Pacific Ocean beach. It is said that no home in the colony is more than 75 feet (23 m) from the sand. Also visible from Surfside is a portion of Anaheim Bay, which is across Pacific Coast Highway and connects to Huntington Harbour.
