The Heritage Golf Classic was first played in Sea Pines Resort in 1969 and has been a regular stop on the PGA Tour ever since. Also in 1969, the Hilton Head Island Community Association successfully fought off the development of a BASF chemical complex on the shores of Victoria Bluff (now Colleton River Plantation). Soon after, the association and other concerned citizens "south of the Broad" fought the development of off-shore oil platforms by Brown & Root (a division of Halliburton) and ten-story tall liquefied natural gas shipping spheres by Chicago Bridge & Iron. These events helped to energize the community, and the Chamber of Commerce started drumming up support for the town to incorporate as a municipality. After the Four Seasons Resort (now Hilton Head Resort) was built along William Hilton Parkway, a referendum of incorporation was passed in May 1983. Hilton Head Island had become a town.
