Statesboro-Bulloch County Parks and Recreation unveiled a proposal Tuesday for a $5.6 million expansion and renovation of Splash in the Boro Family Waterpark, including a wave pool attraction projected to cost almost $4 million. Other parts of the project include a new beach-themed concession area and an expansion of the entrance area to accommodate people waiting for admission. Space will also be added in the winter bathhouse, including a dedicated first-aid station for year-round use.
