The leaves are finally changing color and falling across Kentucky, but there is a right way and a wrong way to dispose of them.
Mark York, Lexington's acting director of the Division of Environmental Policy says leaves and grass that are blown onto the street can clog storm drains.
When storm drains clog with leaves, rain runoff can cause street flooding.
Yard waste that makes it into creeks will decompose, taking oxygen out of the water that is needed by fish.
To properly dispose of your yard waste, city officials recommend using a mulching mower.
Lexington residents can also place their grass and leaves into brown paper bags which will be picked up along with the trash.
Once most of the leaves have fallen, Lexington crews will use large vacuums to pick up piles of leaves along street curbs.
If you see a clogged storm sewer, call 311.
