Never put Yard Waste in storm drains.
Allowing yard waste such as grass clippings and leaves to get into storm drains can clog the system and cause irreparable harm. Although leaves and organic waste are biodegradable, their breakdown process robs valuable oxygen from the water. This stresses and even kills fish and other aquatic life. By composting your grass clippings, yard waste, and other biodegradable materials (e.g., banana peels and eggshells), you will return valuable nutrients and moisture to the soil. Do your part! Water is life. Let’s rescue it – together.
What you can do:
- Never put yard waste in storm drains or creeks
- Use your green waste container
- Leave grass clippings on the lawn
- Start a compost pile. See below for a schedule of free home composting workshops available throughout the County and information on reduced price compost bins available in most areas of the County
- Use organic mulch
Don’t pour it on. Use care. Use less.
As Contra Costa residents, we live in an environment surrounded by beautiful creeks, rivers, the Delta and the Bay – each important to our everyday life. It’s up to us to make sure that we keep our water clean and healthy today and in the future.
Over use of pesticide products is not healthy for your garden or the environment. Please use these products sparingly, follow the instructions on the label, and avoid applying these products on rainy or windy days. Better yet, use less toxic alternatives. This will help prevent run-off into storm drains and our waterways.
When the pesticide container you’re using is almost empty, rinse it and your application equipment at least three times and pour that diluted mix on your lawn. If an accidental spill happens, cover the area with sawdust or kitty litter, sweep it into a plastic garbage bag, and take it to a household hazardous waste facility.
