Trees

FAQs

  • Is this a City tree or my tree?  
    Check the Public Viewer to determine whether the tree is close to the property line. If unable to determine, contact the City Arborist to make a final determination.
  • Can I fertilize my trees?
    A soil test needs to be conducted prior to applying fertilizers. A soil test will tell you exactly which nutrients are missing to make your tree thrive. Learn more about soil tests and the City's Landcare Ordinance.

    Contact the City Arborist.
  • How do I find an Arborist to do work on my private trees?

City Trees in the Road Right-of-Way (ROW)

Every street varies with its road right-of-way width. It can be the back edge of the sidewalk up to 15-20’ from the edge of the curb of the street into the lawn. The first step to determining whether a tree is in the ROW is to check the Public Viewer to see a rough idea where the line is between the road ROW and your property. This is close but not always perfect. For final judgment on whether a tree is a City tree or not please contact the City Arborist who will check street maps and measure the ROW distances to make a determination. If you have surveyed your property in the past or know where your property pins are that helps with measuring the ROW width and is important information to include in your request to the City Arborist. Trees are measured off the center of the tree at the base.

How to use Public Viewer: Type the address into the "find property" search bar and press enter on the keyboard. Select the property you are looking for from the search results and it will automatically zoom in to view the property. You can also use "zoom" manually by using the plus/minus buttons on the top right and left click and hold and drag the screen to center on where you are looking. 

In order to see satellite imagery and the trees, left click the top right button that has 3 horizontal lines. Left click "Basemap", left click "Local", left click "2022 South Portland Aerials".

City Tree Work Requests:

City Tree Inspections: 

Inspections can be requested for trees on City property near your home if you suspect their are issues with their health or damage causing safety concerns to the public. Inspections are conducted by the City Arborist and include a visual general health and risk inspection of the tree. To request an inspection, contact the City Arborist. Generally, inspections can be completed within one week of the request. After an inspection, any work determined to be needed will be coordinated either with our tree contractors or our in house parks crew.

Request City to Perform Tree Work: 

To request that the City perform work on City trees in the right-of-way, contact the City Arborist or submit an online request through VueWorks Request. This will be added to our list of work to be completed. The list is managed in order of risk to the public, not in order it was received. This may take some time to complete especially depending on time of year. If you do not want to wait for our crews availabiliy, approved maintenance may be completed at your own expense by a private contractor. 

Private Contractor to Perform Work on City Trees: 

If you would like to hire a private contractor to complete tree maintenance on a City tree in the right-of-way, fill out a permit application (PDF) for approval and submit it to the City Arborist. Approval from the City Arborist is only required for trees on City Property that you would like your private arborist to perform maintenance on (ie. prune a city tree away from your house etc).

Tree Planting: 

To get on the list to plant a tree in the road ROW in front of your house, contact the City Arborist. Tree plantings are completed as budget and time are available.

Tree Fund: We accept donations to be used to plant trees. If you are interested in donating in memorial of a loved one or just want to help plant more trees in South Portland please let us know.  Make a donation online, or send a check.

Checks can be made out to: City of South Portland with a note for "Tree Fund"
Please send checks to:

City Tree Contractors: 

Most of tree work is completed by our professional tree contractor Asplundh Tree Experts. This company provided a bid and was awarded the contract. The contract goes out to competitive bidding every 2 years. The City's Parks crew does some tree work, mainly from the ground as well as some tasks that can be completed from our small bucket truck.

Tree Work Objectives: Maintenance pruning to include hazard reduction and pruning dead, decayed, or dying branches, weakly attached branches or over extended branches and limbs blocking street signs, stop signs, traffic signals and street lights. Clearance pruning shall be pruned to 14 feet over streets, 10 feet over driveways, 15 feet over house roofs and 8 feet over walkways.

Tree Care Around Power Lines:  Central Maine Power prunes all trees (City and Private) around their power lines on a 6 year cycle. They also do hazard tree removal and storm tree removals around their power lines. They are a private company that maintains their infrastructure and does not work for the city. Visit the CMP website to learn more.

Private Property Trees

Trees on private property are the responsibility of the property owner.  You must be aware of City ordinances before engaging in tree work. To find a list of Maine Licensed Arborist companies see the State of Maine website for a listing.

General Information

Pesticide and fertilizer ordinance:

Major Invasive Insects: 

We have several major invasive insects that threaten our City's trees. 

How the City is proactively managing invasive insects:

Emerald Ash Borer: We have inventoried all of the City Ash trees and inspected their health and Emerald Ash Borer (EAB) infestation level. We have prioritized which trees we are treating to save from EAB. Our contractor will be treating them in late June of 2025. For a complete list of Ash trees and which trees are being treated email the City Arborist. Ash trees that are observed to be too infested to save will be removed due to public safety risk.

View the City's Notification of Treatment for more information on how the City is treating trees for EAB.

View the Oregon Department of Forestry's EAB Treatment Factsheet for more information on treatments for EAB.

Hemlock Woolly Adelgid: We are monitoring our forest trees for this insect.

Brown Tail Moth: This is currently at low population in South Portland this year (2025).

Winter Moth: In 2017, The Maine Forest Service and the City of South Portland released a parasitic fly (Cyzenis albicans) that has been effective in controlling winter moth in Hinckley Park. It was reassessed for efficacy in 2019 and the parasitic fly is controlling the population of winter moth to 40% of its former populations.

Check out the Maine Forest Service links for more info about each insect.
