Cityside Park is a public promenade along Treasure Island’s west shore facing San Francisco’s soaring skyline. The first 6 acres of what will eventually be a 24-acre park will open Sept. 13. TICD contracted CMG Landscape Architecture to build Cityside Park, which will function as a regular city park, with bicycle and hiking paths, a great lawn, 20-foot picnic tables, and barbecue grills.
