Although trees provide many benefits to the City of Ann Arbor, they also have the potential to be destructive to manmade structures such as sidewalks and foundation. Tree roots cause damage through penetration of concrete structures and by the upward movement of concrete material causing fracture.
The objective of this project is to provide the
audience the zones of safe areas to plant trees depending on the tree's
diameter at DBH. I have taken the project a step further. I
provided data to supplement the city and its residents with methods to
plant trees so the roots grow downward to prevent sidewalk destruction
and foundations. Recently, numerous studies have been conducted
for technical considerations for street tree planting, i.e. "critical root
zone." In addition, several contractors can correct root damage
as well as apply techniques to plant trees to prevent root damage.
Again, I will state that I do not support
or recommend any of the methods in this report or other reports.
It is my intent to provide the audience with addition information so they
can make a judgment.
