The Public Works Department maintains City-planted trees in improved Rights-of-Way along certain streets. All trees in un-improved Rights-of-Way are not maintained by Public Works and are the property owner’s responsibility to maintain. Trees located on private property are maintained by the property owner. No trimming or maintenance of a City-maintained tree can take place without prior written consent from the Director of Public Works. For more information about whether a tree is City-maintained or not, please visit the Street Tree page.
