The roots of this tree have invaded our sprinkler system, which now requires a repair of a broken sprinkler line in order to water this side of the yard. We have had a couple of companies let us know that the root invasion is so bad that it'll likely cost thousands of dollars just to have the roots removed in order to get to the sprinkler line so that it can be repaired. In addition, the roots have now lifted the sidewalk approximately 1 1/2 inches and clearly is a public hazard. We have an active community that includes children, elderly, and disabled that use this sidewalk. Thank you for your help.
