Here are a few tips for preventing stormwater pollution from your yard:

Try to clean up after your pet before it rains and dispose of the waste in a garbage can or flush it down the toilet.
Adequately contain your curbside trash so that it won’t leak, fall over, or blow around.
Preserve established trees in your yard and neighborhood.
Don’t overuse fertilizers and pesticides, if you choose to use them.
Plant trees, shrubs, and ground covers that filter pollutants and reduce stormwater runoff.
Don’t cut your grass too short. Adjust your lawnmower to the proper height to reduce runoff from lawns.
Choose to plant native vegetation and or plants that require little or no fertilizer.
Don’t overwater your plants and lawn. Make sure water doesn’t wash over streets and sidewalks.
Recycle yard debris, or use it to make compost, instead of raking it into streets where it can wash into storm sewers.
Compost or mulch can help to hold moisture in the soil and control weeds.
Sweep your garage and driveway into a dustpan rather than into the street.
