Rancho San Pedro was one of the first California land grants and the first to win a patent from the United States. The Spanish Crown granted the 75,000 acres (300 km2) of land to soldier Juan José Domínguez in 1784, with his descendants validating their legal claim with the Mexican government at 48,000 acres (190 km2) in 1828, and later maintaining their legal claim through a United States patent validating 43,119 acres (174.50 km2) in 1858. The original Spanish land grant included what today consists of the Pacific coast cities of Los Angeles harbor, San Pedro, the Palos Verdes peninsula, Torrance, Redondo Beach, Hermosa Beach, and Manhattan Beach, and east to the Los Angeles River, including the cities of Lomita, Gardena, Harbor City, Wilmington, Carson, Compton, and western portions of Long Beach and Paramount.

Redondo Beach is a coastal city in Los Angeles County, California, United States, located in the South Bay region of the Greater Los Angeles area. It is one of three adjacent beach cities along the southern portion of Santa Monica Bay. The population was 71,576 at the 2020 census, up from 66,748 at the 2010 census.
