Landscape and Gardening

Fertilizers, pesticides and other chemicals that are left on yards or driveways can be blown or washed into storm drains that flow to the ocean. Overwatering lawns can also send litter, leaves, motor oil and other pollutants into storm drains.

Unlike water in sanitary sewers (from sinks and toilets), water in storm drains is not treated before entering our waterways. You would never pour gardening products into the ocean, so don’t let them enter the storm drains.

Tips for Landscape and Gardening

  • Prevent erosion of slopes by planting fast-growing, dense ground covering plants that will shield and blind the soil.
  • If fertilizer is spilled, sweep up the spill before irrigating. If the fertilizer is liquid, apply an absorbent material such as cat litter, and then sweep it up and dispose of it in the trash.
  • Do not overwater! Use irrigation practices such as drip irrigation, soaker hoses or micro spray systems. Periodically inspect and fix leaks and misdirected sprinklers.
