This is pretty good idea our City is doing to keep the I just got the news in email and haven't gone over to see the aquatic mats, but plan to.
"These floating MAPS (Managed Aquatic Plant Systems) are located between City
Hall and Winter Springs Highschool. These 800 square feet floating mats are 1/2
inch thick and feature cutouts for aquatic plants. This project involves using multiple
floating mats to make up 5 separate islands totaling approximately
4,575 square feet. Each plant is encased in reusable polypropylene,
allowing the roots to extend into the water. The floating islands
will serve as active biological systems. These plants will remove excess
nitrogen and phosphorous from the water, aiding in pollution removal and
nutrient control. Each island contains up to 8 hydroponic plant species.
Stormwater runoff from urban sources often contains nutrient and
chemical contaminants that negatively impact water quality and ecosystem
health. Floating treatment wetlands are proven to be effective solutions for
cleaning waterways."
