Green Cay Wetlands is a nature preserve located in Boynton Beach, Florida. The 100-acre property was purchased in 1999 from Ted and Trudy Winsberg, who used the property for farming. The Winsbergs sold the property for 1/3 of its appraised value with the condition that it would be made into a wetland. Construction began in July 2003. It was created jointly by the Palm Beach County Utilities Department and the Palm Beach County Parks and Recreation Department in 2004.
