Root pruning / root shaving The careful shaving or cutting back of invasive tree roots that have grown upward and lifted adjacent concrete sidewalk flags.
Shaving down tree roots is often necessary to lay a new, level concrete flag. However, in NYC, you cannot simply chop away at tree roots with an axe. Any root pruning of street trees must be overseen by a certified arborist and approved by the NYC Parks Department to ensure the tree's structural stability is not compromised.
Frequently Asked Questions About Root pruning / root shaving
What is root pruning or shaving?
Cutting back or shaving invasive tree roots that have grown upward and lifted sidewalk flags, so a level slab can be placed.
Can a contractor cut street tree roots in NYC?
Not freely. Root work on City trees is regulated and generally requires NYC Parks approval, with oversight appropriate to the tree's health.
Why are the restrictions so strict?
Removing structural roots can destabilize a mature tree, creating a risk of failure in a storm.
What is the alternative if roots cannot be cut?
Root bridging, slight grade adjustment, or in some cases referral to the Parks Trees and Sidewalks Program.
