Mission Beach is a community built on a sandbar between the Pacific Ocean and Mission Bay. It is part of the city of San Diego, California.Mission Beach spans nearly two miles of ocean front. It is bounded by the San Diego River estuary on the south, Mission Bay Park on the east, and the community of Pacific Beach on the north. A boardwalk runs along the beaches on both the ocean and bay sides of the community. The main artery through Mission Beach is Mission Boulevard. The community is divided into South Mission, a peninsula, and North Mission. At the south end of the beach a jetty, with grass, parking and a walk, extends into the ocean.LandMany residential structures in Mission Beach were built in the 1930s and '40s as summer cottages and some date as early as the 1920s. The rare airplane bungalow on Manhattan Court was built in 1924. Because of problems to work out with developing on sand, Mission Beach developed later than the neighboring communities of Ocean Beach to the south and Pacific Beach to the north. As a result of a new official subdivision in 1914, encouraged by land sales in those next-door communities and a new wooden bridge linking Mission Beach with Ocean Beach, John D. Spreckels offered small lots for sale. As a result, Mission Beach is the most densely developed residential community in San Diego with a land use designation across the majority of its land area of 36 dwelling units per acre. It also has the smallest lots in the city, ranging from to 2,400 square feet (220 m2). Few have been consolidated to form larger lots. Many of the structures within the community have been redeveloped into two-story homes. The wooden bridge to Ocean Beach was closed to traffic in 1950 and demolished in 1951.
