Even small things we do can have a big (negative) effect on our water quality.
Have you heard that plant debris from yards, flowerbeds, and trees can block storm drains and release nutrients that pollute our waterways?

Grass clippings, fallen leaves, and plant trimmings can be easily washed or blown into storm drains or directly into our waters when piled near the roads or waterways. When washed into the storm drains, it can cause clogs and even cause localized neighborhood flooding during rainfall events.
Once the plant matter enters the waterways, it will begin to break down, releasing large amounts of nutrients such as nitrogen and phosphorus. These excess nutrients can fuel algal blooms and lead to fish kills as the oxygen levels become depleted in the water. Keeping plant debris away from drains, rivers, canals, and ponds will help prevent pollution.
Plant Debris Stormwater Solutions
1. Dispose of debris
If you have leaves, lawn clippings, or plant cuttings in your yard rake or collect yard waste into piles. Dispose of it in trash bins or follow composting guidelines to use it as a natural mulch.
2. Leave it alone
Because plant debris has high amounts of nutrients, it can act as a natural fertilizer. Letting leaves and lawn clippings lie where they fall, distributed across your yard, will allow them to slowly break down and the nutrients will absorb back into the soil. Avoid raking them into large piles, which can easily blow away and create dead spots in your yard. As a bonus many critters live amongst plant debris, as it provides food, shelter, and moisture for them. Plant litter can create an important habitat that supports a much larger ecosystem!
3. Keep debris contained
While you can leave plant debris where it fell in your yard, take care to pick up debris that is close to the streets or any areas where it could wash or blow into storm drains or waterways. Creating a clean barrier around your yard will keep plant matter out of our stormwater and keep your yard healthy.
4. Keep a buffer around stormwater systems
Creating a “no-mow” zone around your drains, ponds, or canals can help keep debris out of our stormwater systems by acting as a natural barrier to block it from entering. These natural zones will also help to trap excess nutrients in runoff as they enter the waterways.
