Landscaping and gardening can be major contributors to storm water pollution. Soils, yard wastes, over-watering, and garden chemicals become part of the urban runoff mix that winds its way through streets, gutters and storm drains before entering our river tributaries.
Over-watering lawns and using sprinklers that function improperly not only waste water, but increase pollutants that flow into storm drains.
Chemicals are washed off lawns and landscaped areas killing insects, poisoning fish, and contaminate ground and surface water.
Improper application of fertilizer can cause an algal bloom
. Leaves, grass clippings and tree trimmings that are swept or blown into the street and gutter also cause storm water pollution. These wastes clog catch basins, increasing the risk of flooding on your street, and carry lawn chemicals into the river.
