June 1915 Clarendon Beach opens to the public as a municipal facility, despite the uncompleted state of the bathhouse, which was delayed by a carpenters' strike. Clarendon Beach's first public season comes to a close. Total summer attendance reaches 134,000, held down by the inconvenience of ongoing construction on the bathhouse. 1 March 1916 City Council authorizes the purchase of 30,000 bath towels for rental to the beach-going public when the bathhouse opens three months later. A completed bathhouse and administration building enhances the opening of Clarendon Beach's first season at full operational level.
Patrons pay ten cents apiece for admission to the beach.
Summer attendance totals 408,700. Floodlights are added to permit late-night swimming. Plans call for the closure of Clarendon Beach, in lieu of a larger Montrose Beach to the east on land created by landfill. The city looks for new uses of the Clarendon Beach site as construction of the new Montrose Beach moves swiftly. The privately-owned Wilson Avenue Beach also prepares to close for good.
