Construction at Fernhill

The Western Wetlands, about two acres of “vertical flow, rock filter” treatment wetlands, are under construction. The rock filter system is being built atop the asphalt liner of the former materials handling yard, using a type of rock that supports organisms that remove pollutants from water. Delivery of the rocks will begin on December 13, with up to 33 truckloads per day, Monday – Thursday, through mid-January. The trucks will enter from Fern Hill Road and exit at Poplar Lane. Vertical flow treatment wetlands are another innovation in water treatment that is quite different from the 90-acre natural treatment wetlands to the south that uses a diversity of native plants to filter the water. After the vertical flow filter system is built, the Western Wetlands will be landscaped with native plants. A new ADA accessible trail will circle the new facility.
