From a Baygall Swamp to a bustling railyard that served as the largest employer in Central Florida, Lake Bonnet and its surrounding land played a myriad of roles throughout its history. This 180-acre piece of land adjacent to downtown Lakeland, FL was a working piece of infrastructure up until the 1950s. Fast-forward 60 years to today and to the next role of this derelict brownfield site: a public park. Bonnet Springs Park's visionary mission and technical challenge is to reverse the impacts of former Lakeland Rail Yard operations and create a site where wetlands work to manage and clean an urban watershed, artful landforms conceal decades of contamination, and imaginative horticulture encourages a connection to nature for future generations. This session will explore how innovative designs for brownfield sites, partnering, and funding are remediating the land and transforming it to a new Central Park for Florida.
