 The California Exposition and State Fair Board of Directors are required to maintain and preserve Bushy Lake and the Cal Expo floodplains in a way that is consistent with what a state park and natural preserve are.Assembly Bill 889 also requires that the preservation and management of Bushy Lake and the flood plains of Cal Expo conform to the standards and regulations of the American River Parkway Plan.The Bushy Lake Preservation Act also only allows that parking is to be permitted during the time of the State Fair and only on specified land, however, AB 889 requires one acre of land to be designated at all times for public use as long as cars are not parked there for more than 34 days.
