Huntington completes bioswale project

January 11, 2017 by  

The Town of Huntington recently finished building a bioswale resembling a rain garden at Centerport Beach.

The project will filter 80% of the stormwater that has led to the pollution of Centerport Harbor. A bioswale is a trench or depression that catches rainwater runoff, slowing it down with vegetation like herbs and grasses, and filtering it through organic matter like mulch.

The Huntington bioswale includes 75 trees and eight types of plants native to the area, along with paths made of pavers that are permeable. The bioswale sits on 6,900 square feet that had previously been a parking lot on the beach, and features a curb that is lower on the south side than the north, in order to trap stormwater before it can reach the harbor.

It is important to remove impurities as runoff flows across parking lots, rooftops, roads, and other similar surfaces, picking up pollutants like pet waste, motor oil, pesticides, sediment, and heavy metals, all of which can then contaminate beaches and bays.

Frank P. Petrone, Huntington’s Supervisor, said the bioswale is so beautiful people may think it was constructed simply for aesthetic reasons, but it truly is a natural filter that will clean runoff before it empties into the harbor.

Municipalities like this can benefit by working with a postcard printing company, which can create a card for mailing to residents explaining the project.
