TipStormwater Smart

  • Follow directions on pesticides and fertilizers, (measure, do not estimate amounts) and do not use if rain is predicted within 48 hours.
  • Water your lawn and garden by hand to control the amount of water you use.
  • Set irrigation systems to reflect seasonal water needs. If water flows off your yard and onto your driveway or sidewalk, your system is over-watering.
  • Mulch grass clippings or leave them on the lawn. If necessary, dispose in a green waste container.
  • Prevent urban runoff by taking your car to a commercial car wash whenever possible.
  • When cleaning around the house choose soaps, cleaners, or detergents labeled “non-toxic,” “phosphate free” or “biodegradable.”
  • When cleaning your car, shake floor mats into a trash can or vacuum to clean.
  • Take your vehicle to a commercial carwash where the washwater is recycled and sent to the sanitation district.
  • Use a nozzle to turn off water when not actively washing down your car.
  • Monitor vehicles for leaks and place pans under leaks. Keep your car well maintained to stop and prevent leaks.
  • Use cat litter or other absorbents and sweep to remove liquids left by vehicles or any other kind of outdoor “wet spill.”
  • Perform automobile repair and maintenance under a covered area and use drip pans or plastic sheeting to keep spills and waste material from reaching storm drains.
  • Never pour oil or antifreeze in the street, gutter or storm drains. Recycle these substances at a service station or used oil recycling center.
  • Store household hazardous waste (HHW) in closed, labeled containers inside or under a cover and dispose of them at an HHW collection center.
  • Do not hose down your driveway, sidewalk or patio. Sweep up debris and dispose of it in the trash.
  • Always pick up after your pet. Flush waste down the toilet or dispose of it in the trash.
  • Bathe pets indoors or have them professionally groomed.

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.
