This maple has been planted many moons ago by the city on the city right of way in front of my house. Its roots have been growing in my front yard. Mowing the lawn has become a pain but it's bearable. But should I be concerned about these roots doing some sort of damage to the foundation of my house in the long term? The main cast iron sewer pipe from 1960 between the house and the street is located near the tree and it gets clogged with roots every few years. Can the roots cause the pipe to collapse?
