Oyster Bay Goes Green with New Rain Garden
By Amy Mandelbaum and Mark A. Tedesco
Did you ever stop to think where water goes after it leaves your downspout? If you’re like most people, once stormwater is out of sight, it’s out of mind. Most likely, the stormwater rushes down your driveway, onto the street, and to the nearest storm drain. If you don’t live in the Big, I mean, Green Apple, then that drain goes directly to your local waterway, whether it be a lake, creek, river, bay, estuary, or even the ocean. So, what’s the big deal?
Well, that stormwater isn’t so clean by the time it makes it to your local waterway, as it picks up litter, nutrients, and plenty of other things along the way. This polluted stormwater runoff goes directly into the water without having a chance to be cleaned.
So, what can we do about it? That’s where green infrastructure comes into play. Green infrastructure is essentially mimicking what nature did before we started building gray infrastructure, such as gutters, roads, pipes, etc. Out of the many green infrastructure practices, one of the best for filtering polluted stormwater runoff is a rain garden: a shallow, vegetated basin that captures, treats, and infiltrates polluted stormwater runoff within a day. It is designed to treat the first inch of rain, which is the most polluted, and the plants, soil, and mulch filter the polluted stormwater runoff before it enters your local waterway.
The Town of Oyster Bay realized the need to redirect the polluted stormwater runoff from the roadway along the waterfront before going into nearby Oyster Bay, a Long Island Sound Stewardship Area, and eventually Long Island Sound. The Town sought and received a Long Island Sound Futures Fund grant to install a rain garden, all while educating the local community. The rain garden was installed in October, with assistance from other local organizations and volunteers. As part of the project, a corresponding rain garden training program is also offered for homeowners, municipal officials, and landscape professionals. This rain garden now serves as a demonstration to the local community and its visitors of a green infrastructure practice that can be easily incorporated into the landscape.
So, the next time it rains, I hope you take a closer look at your downspout.
