Street Tree Replacement and Planting
Homeowners interested in obtaining replacement or new street trees for the tree belt in front of their homes should contact the Urban Resources Initiative (URI). This Yale University-based program handles this effort under contract for the New Haven Department of Parks, Recreation and Trees and builds stewardship for New Haven's urban forest. Call URI for information on how to get a new tree for the front of your house or any neighboring tree belt. The trees are planted for free as long as the requester commits to watering the tree after it is planted.

Adopt-A-Tree Program
The Department of Parks, Recreation and Trees is sponsoring an Adopt-A-Tree Program for the residents of the City of New Haven. Our beautiful street trees are an asset to our neighborhoods. They provide shade in the summer and act as a barrier for noise. Trees beautify our streets and produce life sustaining oxygen and trap air pollutants. They also decrease noise, increase property values and enhance civic pride.

Adopt-A-Tree Program Adopt-A-Tree Program


Join your neighbors this year and adopt a street tree in front of or near your house or apartment, or place of work. To obtain a certificate for adopting your tree, we ask that you commit to the following care for your adopted tree:

  • Water the tree at least twice weekly during the spring and summer.
  • Mulch the soil to conserve moisture and improve health. It is a good idea to plant flowers or ground cover around your tree and keep the root area neat and clean.
  • Follow the recommendations included in your Adopt-A-Tree packet.


Trim-A-Tree Program
Healthy and attractive trees add to the aesthetic value of your neighborhood and can increase your property value. Applications are available on-line (click here to download) or at the Parks Department Maintenance Division Office, 180 Park Road, Hamden, CT 06517 for tree pruning and shaping.
