Ash Trees in Right-of-Way
The City has developed a plan where all ash trees in the right-of-way must be either treated or removed in the next five years. The City will be responsible for any trees that are removed, but residents who are interested in treating ash trees that are located on city right-of-way must follow a permit system. The permitting system is free and necessary for our Parks Department to keep track of which city trees have been treated.
Here is how the process works:
The City of Johnston is no longer allowing first time treatments for Emerald Ash Borer. If you are currently treating your tree(s), please contact the Johnston Parks office at 515-727-8091 to make sure you have a current permit. There is no charge for the permit.
If you have a question about the health of your ash tree in the right-of-way, please contact the parks office and a representative will evaluate your tree.
If there is an ash tree located in the city right-of-way near you, and you would like to treat it against Emerald Ash Borer, and return it to the Johnston Parks Department. Forms may be taken to Crown Point Community Center at 6300 Pioneer Parkway, where the Parks Department is located, or mailed to Johnston City Hall at P.O. Box 410, Johnston, Iowa 50131.
The injection treatment for ash trees located on the city right-of-way must be done once every two years and treatments range from $150 to $400, depending on the size of the tree. The city recommends getting a couple of estimates. The city Arborist has determined that injection is the most environmentally-friendly way to treat a healthy ash tree against Emerald Ash Borer. The city will not permit trees to be treated with soil injections or soil drenching to reduce the potential for chemical runoff and groundwater contamination. Only trunk injections will be permitted. Treatment is not always a guarantee that a tree will survive EAB. For ash trees located on private property, residents and business owners may treat their trees however they wish, though city staff recommends trunk injections over drenches and sprays due to environmental concerns.
