Tree ordinances are important for protecting the community forest and public safety. These municipal regulations provide authority over trees, define responsibilities, offer guidance to residents and establish minimum standards for a community’s tree program. Most tree ordinances are focused on publicly-owned trees such as street trees, park trees and trees in public spaces.

Tree ordinances are a tool that help local officials implement community forestry programs. They provide guidance to residents, developers, landscape architects, utilities and private contractors when it comes to trees.

Washoe County
Washoe County’s Parks & Open Space staff are responsible for maintaining public trees in County parks.
