Tree Planting

Planting trees on public property

Planting trees on public property in Waterloo is an important part of maintaining and improving our urban forest. In many neighborhoods, the lots do not provide sufficient space to support trees. In such instances, plantings located on public property provide a majority of the overstory vegetation.

The City of Waterloo Leisure Services Department encourages property owners to plant trees on the City owned right of way between the sidewalk and the street. If you choose to plant a tree in this area you must “plant the right tree, in the right place”.

Tree Planting Guidelines

The following guidelines will help prevent future maintenance problems and reduce potential hazards.

Notify the City Forester

City Code 7-5-3(a) requires a property owner to receive a permit from the City Forester before a tree is planted on public property. The City Forester will determine the best location for the planting and advise as to the suitability of the proposed variety.

Locate All Buried Utilities

It is the responsibility of the person planting the tree to locate all buried utilities. (Iowa One Call: 1-800-292-8989)
