Approval of proposal from Beemats, New Smyrna Beach, FL, in the amount of $171,072.00 for the annual harvesting, maintenance and re-nourishment of vegetated mats at the Indian Hills Recreation Area.

The Indian Hills Recreation Area stormwater treatment utilizes a vegetated floating wetland system to improve the water quality prior to discharging excess stormwater to the Indian River Lagoon.  This system consists of mats made of a buoyant material fitted with perforated pots which are planted with specific aquatic plants to absorb and store excess nitrogen and phosphorus from the water column.  A total of twelve (12) islands will be maintained every four (4) months, which consists of trimming the plants, collecting and composting the plant biomass, collecting samples for laboratory testing and reporting results of removed nutrients.

The floating mats have exceeded their life expectancy (7 years).  A replacement program has been implemented to replace the old islands over a three-year period.  In 2022 five mats were replaced and the anchoring systems refurbished.  This year four islands will be replaced.
