In 2002, a group of five Port St. John residents formed "Port St. John For Tomorrow"^[7] (PSJ4T) and tried to incorporate the Port St. John area.^[8] Included in PSJ4T's incorporation plans were five separate communities: Delespine, Williams Point, Hardeeville, Frontenac and a part of Sharpes.^[9] PSJ4T had not informed^[10] these five communities. When the five communities did find out, they expressed disinterest in being included in the incorporation effort.^[11] A feasibility study^[12] was requested by PSJ4T members.^[13] Voters approved the study.^[14] The study was funded by Brevard County^[15] and performed by the University of Central Florida.^[16] The five reviewing committees in Tallahassee said the study was "deeply flawed.".^[17] The county allowed the residents of Port St. John and the five communities to vote on becoming a city. Howard Futch^[18] and Randy Ball (CS/HB 1071)^[19] sponsored the bills in the Senate and House.^[20] The incorporation issue was defeated in November 2002, 73% to 27%,^[21] including most of the people in the five communities.^[22] State statute prevented Port St. John from considering incorporation for ten years.

In 2012, the area received national attention when a mother shot and killed her four teenagers and herself.^[23][24]
