The following statement is provided by Portland Parks and Recreation Urban Forestry:
The best protection for sidewalks is to plant the right tree in the right place. However, extra protection can be taken by installing root barriers at the time of planting. Root barriers guide roots downward and away from infrastructure and therefore may help prevent sidewalk damage and reduce sidewalk trip hazards. Root barriers are required by Portland Parks and Recreation Urban Forestry for all planting sites less than 4 feet wide, and are recommended for all other street tree planting sites. Root barriers are panels or rolls of rigid plastic either 12" or 18" high and a few millimeters thick. The rolls are cut, or panels lock together, to achieve desired length, which is 6' long.
We'd love to help you plant this tree, but first we need you to make sure
we are planting in your neighborhood and that the city allows this tree for
your home. Let's start by checking your address. Or if you're already
approved, logon here.
As a non-profit we rely on government support, foundation support, and individuals like you to plant your trees. Together we will make the urban forest greener for everyone.
The quantity of trees exceeds the number available. Please adjust quantities accordingly.
