  • When do I need a tree permit?

    Generally you need a permit to remove trees, whether on private or public property. Residents also need permission to prune or plant trees located in city rights-of-way.  If you are not sure if you need a permit, call the city arborist at 302-227-6181, ext. 206.

  • Why do trees need to be protected during construction?

    Any construction activity or digging under a tree’s canopy (or the “dripline”) can harm or kill the tree. A majority trees' roots are in this zone and within the top two feet of the soil. Cutting roots and compacting soil should be avoided as much as possible. 

  • What can I do if a tree is damaging my sidewalk?

    If the tree is on city property and was planted by the city, call the city arborist at 302-227-6181, ext. 206. The city will evaluate both the tree and sidewalk to decide on the best course of action. If the tree is on private property or wasn’t planted by the city, the city may still be able to provide advice.

  • What can I do about tree roots getting into my sewer lines?

    Typically, tree roots only invade old lines where there is a leak. Clay pipes are especially susceptible to root intrusion. Rarely do tree roots enter or crush sewer lines that are in good condition. A plumber can use a camera to diagnose tree root intrusion. The best solution is to replace the sewer line, but root removal from the pipe and sewer line repairs may also be an option. The city typically will not remove a tree for issues related to sewer conflicts if there are other viable options.
