Mile Square Regional Park is a park located in Fountain Valley, California. It includes two lakes, three 18-hole golf courses, archery range, baseball and softball fields, picnic shelters, and a 20-acre (81,000 m2) urban nature area planted with California native plants, a 55-acre (223,000 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.
