What is one of the components of a street tree ordinance that helps protect trees?

One of the key components of a street tree ordinance is the specification of tree species and height requirements below utility lines. This is essential for several reasons. Firstly, it ensures that trees planted in proximity to utility lines will not grow into a height that could interfere with electrical wires, thereby minimizing the risk of power outages and safety hazards. Proper species selection based on expected mature height is critical to promote healthy growth and longevity of street trees, as well as to maintain the aesthetic and functional integrity of urban landscapes.

By enforcing height requirements, municipalities can also reduce the need for frequent pruning, which can stress trees and may lead to weakened structures. This aspect of the ordinance fosters a healthier urban forest by encouraging species that will thrive without conflict with utilities, thus promoting sustainability and reducing maintenance costs for the city. Furthermore, this ordinance helps the community to maintain clear sightlines and reduce the risk of property damage, enhancing public safety.

While the other components mentioned also have merits, they do not specifically address the direct interaction between trees and utility infrastructure, which is a critical consideration in urban planning and tree management.
