About the Forestry Division

The Forestry Division maintains trees growing in the public right-of-way and on other City property, including parks, trails, golf courses, and open space. Through planting, pruning, inspections, proactive tree care, and branch recycling, the division promotes public safety, improves tree health, and grows a resilient urban forest. The Forestry Division also issues permits for work on City-owned trees, provides guidance on tree care and hiring a licensed arborist, answers questions about trees on private property, inspects privately owned trees for insect and disease concerns, and offers volunteer opportunities that help care for Louisville's urban forest.

Who is responsible for maintaining a tree?

If a tree is growing on your property, you are responsible for maintaining it, including branches that extend over public sidewalks, streets, alleys, and other public rights-of-way. Trees growing in the public right-of-way or on other City property are maintained by the City.

What types of trees can I plant in the public right-of-way?

All trees planted in the public right-of-way require a permit and approval from the City Forester. Certain species are prohibited because they are invasive, produce excessive cotton or fruit, have weak wood, or are likely to create future maintenance or sidewalk clearance issues. Prohibited species include cotton-bearing cottonwoods, boxelder, Siberian elm, Russian olive, and silver maple. Ornamental and fruit trees with low-growing branches, such as crabapple, hawthorn, and fruit trees, should also be avoided.

Who should I hire to work on my trees?

For large trees, hazardous work, or trees showing signs of disease or decline, the City recommends hiring a licensed and insured arborist who employs an ISA Certified Arborist. Before hiring a tree care company, get multiple estimates, verify the company's City license and insurance, and pay only after the work is complete.

Can the City require my neighbor to prune or remove a tree?

Only if the City Forester determines the tree poses a public safety hazard or violates the Louisville Municipal Code. Most issues involving privately owned trees, such as branches extending over a property line, are civil matters that must be resolved between neighbors. The City Forester can provide guidance and help identify possible solutions.

Is topping a tree recommended?

No. Topping removes a tree's upper branches and is considered a harmful pruning practice. It weakens the tree, increases the risk of insects and decay, creates weakly attached regrowth that is more likely to fail during storms, and shortens the tree's lifespan. Proper pruning improves tree health and safety without causing these long-term problems.

Will the City pick up fallen tree branches?

The City removes fallen branches only when they obstruct a public street, sidewalk, or other public travel area and cannot be safely moved by the property owner. Property owners are responsible for disposing of branches from trees on private property. Residents can use the City's seasonal Branch Drop-Off Site for disposal.

Where can I learn more about tree care?

The International Society of Arboriculture (ISA) and American Forests provide reliable information about tree planting, pruning, and long-term tree care. You can also contact the City Forester with questions about trees in Louisville.

Do I need a permit to work on a tree?

A permit from the City Forester is required before planting, pruning, spraying, removing, or otherwise working on any tree growing in the public right-of-way or on other City property. No permit is required to work on trees growing entirely on private property unless otherwise required by the Louisville Municipal Code.
