Water Quality

'Green' Gardens

What we do in our yards can either have a good or adverse effect on the water quality of our streams and lakes. Distributing natural vegetation, using excess lawn chemicals and not disposing of grass clippings can create a mess of problems. So before you reach for a spray gun or fertilizer spreader, please consider the impact it may have on our water.


Eco-friendly H2O Tips

  • Only use safe (and whenever possible) organic lawn products. Read all instructions and use product sparingly.

  • Never apply lawn chemicals near waterways.

  • Don't dump leaves or lawn clippings in a nearby stream. Compost it. (See below.)

  • Keep storm drains near your home clear of debris.

  • Use gravel and stepping stones in place of concrete for patios and walks to help increase soil absorption of water runoff.

  • Rather than plastic film, use straw or unity fabric for mulch and ground cover.

  • Angle gutter downspouts away from storm drains.
