||Glynlea Park is located in southeast Jacksonville, south of Atlantic Boulevard in the Glynlea Park/Holiday Hill community. Development of the Glynlea and Holiday Hill neighborhoods began in 1948 and 1955 respectively. The facility opened as a Duval County park in 1956, and that same year the Southside Youth Athletic Association (SYAA) was formed and has been providing youth programs at the park ever since. The Glynlea-Holiday Hill Association purchased two parcels at the park in 1956 and 1962, and built and operated a community building and private swimming pool for a number of years. After the City re-acquired the parcels in 1985, the structures were demolished. The SYAA, which sent two boys (Storm Davis and Joel Davis) from its baseball program to the major leagues, has worked with the City over the years to improve and maintain the park.
