It includes two lakes, three 18-hole golf courses, an archery range, baseball and softball fields, picnic shelters, a 20-acre (81,000 m2) urban nature area planted with California native plants, a 55-acre (220,000 m2) recreation center with tennis courts, basketball courts, racquetball courts, a gymnasium, the Kingston Boys & Girls Club, and a community center.
This regional park was built on a naval landing field soon after the city was incorporated.
James Kanno, one of America's first Japanese American mayors, led the effort to create the park.
[1] The park derives its name from the near-perfect square of land that it occupies, bounded by Edinger and Warner Avenues on the north and south sides, and Brookhurst and Euclid Streets on the west and east sides, respectively.
In March 1967, Orange County entered into a long-term lease with the Navy Department for the perimeter area of the site which allowed the county to develop this area for regional park purposes.
