As part of phase 1 of the master plan, Soissons Landing was upgraded with new ferry docks and a waiting plaza, while the Parade Ground was regraded for lawn sports, while the Historic District gained concessions. In 2013, construction started on a new potable water connection (which replaced a locally illegal connection from the Brooklyn-Battery Tunnel) as well as repairs to the seawall. The Liggett Terrace courtyard was built in 2014, as was Hammock Grove and a new play structure. The Oyster Pavilion opened in June 2015, followed by the Hills section of the park in July 2016. The island became more popular over the years. While it attracted 275,000 visitors in 2009, over 800,000 people came to the island in 2018.
