Construction Notices

We will do our best to minimize the impacts on residents and business. Construction notices will be delivered to all residents and businesses in the impacted area(s) prior to work taking place. The notices will outline the work taking place, a schedule overview, and information on associated impacts, such as parking restrictions and driveway access:

  • Initial Notice – This notice will be distributed approximately one week prior to work commencing.
  • Two Day Notice – A final notice will be provided two days before the activity begins to serve as a reminder of the upcoming work and associated impacts.

In addition, parking notices will be posted in the areas where parking will be impacted. During these activities, there will be intermittent road closures and parking restrictions. Streets and driveways may be inaccessible for intermittent periods during the day but will be accessible every night.

We appreciate your patience and support while we work to execute these improvements throughout our community! If you have any questions about the Monrovia Renewal Project, please feel free to contact Public Works at (626) 932-5575 or

We recognize that construction can be messy and inconvenient, and we appreciate your patience through this process!

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 them in coordination with ongoing or upcoming Monrovia Renewal construction activity.
As a 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.
If you have any questions or concerns, please contact the Public Works Division at (626) 932-5575.

A Note on Construction Schedules...

We are committed to providing you with timely updates on the project's progress and the construction scheduled to take place. Unfortunately, in construction, schedules frequently change at the last minute, due to weather conditions, crew availability, coordination with other agencies, and other unforeseen conditions. We strive to update when these changes occur, and we thank you for your flexibility in advance!

Sewer Cleaning and Closed-Circuit Television (CCTV)

As a part of our routine maintenance program and to facilitate the design of Monrovia Renewal repairs, all of the sewer lines in the City are being cleaned and inspected using Closed Circuit Television (CCTV) technology.

When National Plant Services is out in the field, they use a jetter (or cleaning truck) and a box truck containing the television equipment. The equipment is situated next to sewer manholes located in the road, and the crew takes about 30 minutes at each manhole location. The lines are first cleaned and then inspected utilizing the television equipment.
