Trees to be Removed and Replaced Related to Monrovia Renewal Work

Throughout the City, a number of trees have been identified as being problematic due to their health and condition, as well as the impact they are having on the infrastructure. These trees have been assessed for their overall health and condition and for opportunities to minimize their impact on the infrastructure (such as root pruning or installing root barriers). The ultimate goal is to preserve as many trees as possible; however, in situations when the health of the tree is declining and the trees are impacting the infrastructure, a decision has been made to remove then in coordination with ongoing or upcoming Monrovia Renewal construction activity.

As part of the replacement of the sidewalk, the tree wells will be left intact so that new trees can be planted back in their place. The Field Services team is working to identify suitable replacement trees and will work to replace them when the construction is complete and the planting season is desirable.

As the work in this section progresses, we will be sure to keep you updated on any developments. As always, we thank you for your patience and understanding while we work to execute this project! Should you have any questions or concerns, please feel free to contact the Public Works Division at (626) 932-5575 or
