What is Sediment Keep Yard waste Out of the Storm Drain Collection Practices for Professionals Working in Streets
What is Sediment
Sediment is the scientific term for mud, dirt, and soil. While it is a natural part of the environment, too much of it in one place can pollute our streams, lakes, and rivers. Sediment runoff into our streets and stormwater drains negatively impacts the health of local streams by degrading habitat for aquatic life, decreasing recreational value, and promoting growth of invasive plant species and algae.
Keep Yard waste Out of the Storm Drain
Did you know?
Yard waste can can ruin creeks and lakes. Leaves and other yard waste flow through the storm drain to our creeks, streams, lakes and rivers. When the leaves and other yard waste decay it uses up oxygen and releases pollutants that can kill plants and other organisms that live in our waterways.
Yard waste in streets and storm drains:
- Is dangerous for cyclists and motorists;
- Ruins creeks and lakes – Yard waste decays in the water using up oxygen and releasing pollutants that can kill plants and other organisms;
- Can cause flooding; and,
- Leads to more stormwater maintenance costs. We spend thousands of dollars a year to flush out clogged storm drains.
Here's how you can help:
- Leave grass clippings on the lawn (they’re good fertilizer)
- Mow away from the pavement
- Sweep or blow clippings back onto the lawn
- Make compost! Mix grass clippings with leaves and soil
- Keep leaves off the street
There are a few options when collecting leaves and grass clippings:
Year-round - Do yard waste curbside pickup with the City of Raleigh.
Seasonal - Take part in loose leaf collection from November to February. This is for residential properties only. Commercial properties should bring their leaves and grass clippings to the Yard Waste Center.
