We determine the locations and the number of trees to plant in parks. We select types of trees that will help increase urban forestry diversity, and we plant during the season that is best for the tree.
Tree Placement Guidelines
We follow several placement guidelines when we plant trees to reduce future maintenance. Before we consider a location, we make sure it is an appropriate environment for the tree.
Trees Near Overhead Wires
Trees Near Infrastructure
Tree Species Diversity
We are committed to maintaining a diverse population of trees.
Following the devastating loss of American Elms due to Dutch Elm Disease in the 1970s, species diversity became an important consideration when determining new trees to plant. This is why we typically plant a wide variety of tree types in each park.
Species diversity helps reduce the losses that may occur from a future insect or disease infestation.
Trees We Plant
Planting in Woodland Areas (Natural Areas)
We do not actively plant trees in woodland areas.These areas regenerate and new trees grow naturally on their own. If we must remove trees in a natural area to control an invasive species, we will plant new trees and speed up the natural regeneration process.
We routinely prune to keep our city beautiful and maintain the health of our trees in parkland areas.
Reasons to Prune
- Remove limbs that may fall and hurt people
- Provide clearance for signs, signals or street lights
- Reduce potential of criminal activity
- Remove limbs that may fall and damage property
- Remove limbs that rub against buildings
- Reduce potential of criminal activity
Maintain traffic flow
- Provide clearance for signs, signals, street lights, and pedestrians
- Remove unhealthy branches
- Fix growth defects
- Lower wind resistance
Pruning in Woodland Areas (Natural Areas)
We only prune in woodland areas to make them safe for the public and to provide clearance for pathways, roads, signs, and street lights.
We will remove a park tree if the tree:
We pay to remove park trees.
Marking and Notification
We will mark park trees we need to remove as follows:
Green Paint Ring
The tree has Emerald Ash Borer and will remain marked for five days. After five days, we will remove the tree as soon as possible.
Green Paint X
We will remove the non-symptomatic tree as part of the canopy replacement plan for ash trees.
The tree is not currently scheduled for removal. We wrap non-symptomatic public ash trees with informational ribbons to raise awareness for the canopy replacement plan for ash trees.
We only use green to mark ash trees.
Orange Paint Ring
The tree has Dutch Elm Disease and will remain marked for five days. After five days, we will remove the tree as soon as possible.
Orange Paint X
We will remove the tree for another reason. For example, it is dead or dying.
We make the final decision about boulevard tree removal, but will do our best to answer any questions you have.
Tree Stump Removal
We hire private companies to grind stumps because it is more cost effective. They grind the stump below the surrounding soil or deeper if we need to plant a new tree in the same spot.
We first grind stumps in locations where we need to plant new trees (referred to as “deep grinds”). Then, we remove stumps on a street-by-street basis (“regular grinds”). We may remove a stump the same year the tree was cut down, or the next year.
The budgeted funds available determine how many stumps we can grind and when. We may not have the resources to remove every tree stump each year.
Removal in Woodland Areas (Natural Areas)
We do not remove trees from woodland areas unless they are dangerous or diseased. If a tree has the potential to fall, or is located where it could cause harm to people or property, we will remove it. For example, a tree near a path could be dangerous, but a tree in the middle of a natural area away from paths or roads is not dangerous.
If there is a fallen tree wedged between other trees or resting on a weak branch, we may need to make it safe. We will not remove the tree from the site, but will rest it safely on the ground. The tree will naturally decompose and will not damage nearby trees.
We may remove diseased trees from natural areas to protect the trees around them.

The maps are a good representation of park trees, but may have some inaccuracies because the trees in our parks change constantly. We update the tree data yearly.
