All parkway trees are owned and maintained by North Riverside Public Works. If a tree is dead or diseased, Public Works will have it removed. If the parkway tree is not dead or diseased, we will NOT remove the tree.
Tree trimming happens on an as needed basis. The Director will conduct several surveys to monitor trimming needs and pertain to those needed during the spring and then fall months.
All trimming is completed by a contractor and to trim according to specifications set by Public Works. We trim the tree over the curb line at a 17 foot height. Walkways are trimmed to balance and at a height of 8 foot on dry conditions to avoid branches hitting walkers or bikers. Any crossing, dead or damaged branches also will be removed. The expense of all tree service is paid for by Public Works.
If you have a parkway tree in front of your home, it’s suggested to rod your sewer line every 2 years to prevent root blockages.
Tree planting is a service provided through Public Works as well. If you would like a tree on your parkway, you are to call Public Works and be placed on the planting list. In the late summer, our very own Garden Club will contact those interested and explain the different types of trees offered and mark out the best location for your new tree. Once again this program is free to our residents. All planting will occur when the tree is dormant. Typically the planting season is early November.

Caring for Your Tree
For the first two years of a tree's life, consistent moisture is key in the development of its root zone. Watering once a week at the base of your tree for one hour with your hose at a very slow trickle is best. If Mother Nature isn't co-operating and we are experiencing extended hot and dry days, a new tree may need watering as often as three times a week to insure the root ball does not dry out.
To help mositure remain in the soil and keep roots actively growing, apply a 2-4" thick doughnut ring of mulch (keep soil from touching the bark) at the base of your tree each year. Not only will mulch assist in moisture retention but it also protects tree bark from lawn mower damage, deters weed growth and prevents soil erosion.
Do not apply too much mulch! Volcano mulching (see below), applying too much mulch by piling it up against the trunk, is detrimental to the health of the tree. Too much mulch can kill a tree by suffocating it, encouraging abnormal root growth or cause the bark to rot.
Follow the 2-4" high doughnut ring rule and your tree will love you for it!
Emerald Ash Borer
Emerald Ash Borer is the newest and most destructive insect we have seen in years. If you have an Ash tree and think it may be diseased, please call Public Works. Typically you will notice the following on an infected Ash tree:
- The crown or top of the tree will start to die back first.
- You will notice new sucker growth from the base of the tree or just above the crotch of the tree with some bark splitting.
- Wood Peckers will start to appear trying to get at the larva just under the bark.
- You will also notice serpentine galleries and D-shaped exit holes within the trunk of the tree.
- Soon, you will see branches large and small starting to fall.

Public Works has been applying a Merit Drench every spring since the insect was observed in Michigan several years ago.
Our hope is to delay the infestation of our Ash trees and/or until the Department of Agriculture or another agency can introduce a predator or cure to kill off this borer and eliminate from our territory.
