In late 2016, the City of Ormond Beach designed a floating wetland component, as part of the stormwater treatment system, for a chain of ponds in the central portion of the city. We installed 5,888 square feet of Beemats floating wetland islands in a 2.71 acre lake, covering 5 % of the surface area of the water body. Over the past five years, the freshwater aquatic plants growing on the wetlands have removed 983.21 pounds of nitrogen and 32.3 pounds of phosphorus from this pond. During the first two years, stored nitrogen in the water caused explosive growth of the wetland biomass and impressive nutrient harvests. After 2019, the nitrogen levels moderated in the water column and subsequent harvests have been more balanced with the phosphorus levels.
