||Black Hammock Island Park is located in the extreme northeastern section of Jacksonville near the Nassau River. Only about five families lived in the area in 1971, but with the building of paved roads in the late 1970ís and early 1980ís, the start of mail delivery and garbage service, and the opening of the Dames Point Bridge in 1989, a population boom began. The City purchased the property in 1981, and the first facility built at the park was the community center in 1985. Since the parkís inception, the islandís Civic Association has played a leading role in the development and management of the property. City-funded improvements made over the years include expansion of the community center in 1990 and construction of two tennis courts and a walking/jogging trail in 1996.
