Yard Waste

Remove leaves from storm drains to reduce water pollution and flooding.

Fallen leaves are loaded with natural fertilizer, which can cause water pollution that harms people and animals. Leaves that are left near the side of the road can also cause flooding when they block storm drains and waterways.

Keep the ponds and waterways in your community clean and healthy this fall with a few simple steps.

  • Never dump leaves in wetlands or waterways (it's harmful and illegal)
  • Bag leaves in paper bags for disposal by your town (check your town's disposal schedule)
  • Compost your yard waste at home in an area away from wetlands and storm drains
  • Keep paved areas and storm drains clear of leaves
  • Make sure your lawn service is properly disposing of all your waste
  • Mow your leaves with a mulching mower and let them stay them on the lawn as a natural fertilizer

Leaves as Water Pollution? Really?

Freshly fallen leaves contain a natural fertilizer called phosphorous.

When leaves fall in the autumn, they quickly begin to decompose, and rain washes the natural fertilizers out of them. When leaves fall in a forest or on your lawn, these fertilizers get recycled into the soil and trapped there, helping plants grow in the spring.

But when leaves, grass clippings or other organic materials, get dumped into wetlands, waterways or ponds, those natural fertilizers go right into our water and cause problems.

Similarly, when leaves or other yard waste are left on paved areas, rain washes those natural fertilizers into storm drains in your neighborhood that lead right to our waterways without first going to a water treatment plant.

Dumping of leaves can also cause blockages in storm drains and waterways that can cause flooding.

The Problem with Phosphorus and Our Water

When phosphorous gets added to streams, ponds and wetlands, it serves as an especially powerful fertilizer in the water.

It encourages lush growth of pond weeds and algae in the spring that can interfere with swimming, reduce the amount of oxygen in the water needed to sustain fish and aquatic life.

In severe cases, can contribute to the growth of cyanobacteria "blooms" that can be toxic to people and animals.
