Defect Code 7
Tree Root Damage / Heaved Flag
Street tree roots heave and crack sidewalks. NYC DOT cites the property owner, but Parks owns the tree. We coordinate Parks-approved root pruning, replace the heaved flags, and install root barriers to protect the new pour.
Signs You Have This Violation

- Flag tipped up at the tree-pit side
