This state beach was named in memory of State Assemblyman Robert W. Crown, who campaigned for the site's preservation as public parkland. Known as Alameda Beach from the 1880s until the outbreak of World War II, it was an amusement center and day-trip destination for San Francisco and Bay Area residents. The beach is a great achievement of landscaping and engineering. After wind and water action had eroded the beach dangerously, it was restored in early 1982 with sand from San Francisco Bay, pumped ashore by pipeline from a barge. More sand has been added since then, and groins have been constructed to keep it in place.
