The Wrigley Greenbelt is a 12-acre site along the east bank of the River between 34th Street and Willow Street in the City of Long Beach. The City's General Plan identifies the zoning of the site as public open space. On April 20, 2000 Los Angeles County Public Works held Earth Day 2000 at the site between Spring Street and Willow Street. Fifty sycamore and cottonwood trees were planted on one half of the site, with the support of the neighborhood association, Wrigley Association. The other half of Wrigley Greenbelt is also landscaped with trees and located along a residential neighborhood.
