The City of West Palm Beach submitted a petition on May 27, 2020, requesting the Department designate Grassy Waters Preserve, excluding the M Canal, as a Special Waters OFW. Grassy Waters Preserve is 23-square mile aquatic preserve located in eastern Palm Beach County and is wholly owned by the City of West Palm Beach. The preserve is designated as protected conservation land in the City’s comprehensive plan. The Florida Legislature has recognized the significance of Grassy Waters Preserve and has limited its use to water supply, environmental, educational, or conservation purposes.
