Monrovia Renewal Related Construction

Monrovia Renewal is the largest public works project in the City's history, making citywide repairs where they are most needed to our water and sewer pipelines, water facilities, streets, sidewalks, curbs, and gutters. Visit the Monrovia Renewal page to learn more.


Monrovia Renewal is Underway in the North Section!

Monrovia Renewal construction activities in the North are in full swing! The North Section includes all areas located north of, and including Hillcrest Boulevard, Grand Avenue, and Greystone Avenue.  The City’s Contractor – Sully Miller Contracting Company – has crews working throughout various locations in the north, performing mainline sewer repairs, water service line repairs, and concrete work.

Construction Notices

We will do our best to minimize the impacts on residents. Sully Miller will deliver notices to all residents 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:

  1. Initial Notice - This notice will be distributed approximately one week prior to work commencing.
  2. 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 recognize that construction can be messy and inconvenient, and thank you for your cooperation and patience as we work through these improvements!

After Procurement Delays, Terrardo Drive Speed Bumps Installation is set to Move Forward

Just a quick note to let everyone know that we’re making plans to move forward with the installation of speed bumps on Terrado Drive.  If you recall, in late 2018, residents on Terrado Drive submitted a petition asking that the City install speed bumps on their street.  Based on that feedback and an assessment conducted by staff, we made plans in December to coordinate the installation of the requisite speed bumps.

Based on the preliminary engineering work that was done, it was determined that nine speed bumps would need to be installed on Terrado Drive, and based on the cost of the improvements and our existing procurement processes, we coordinated an informal bid which identified Lake Traffic as the low bidder.  However, after awarding the procurement contract for purchasing nine speed bumps to that firm, they became non-responsive, which has required that we look to purchase the speed bumps from an alternative firm.  Given that delay, we are currently around 6 – 8 weeks away from receiving and installing the speed bumps.  We’ve communicated this updated schedule to the residents on Terrado Drive, and if you have any questions about this matter, please feel free to call the Public Works Division, (626) 932-5575.

Minor Traffic Delays at the Intersection of Huntington and Myrtle the Week of March 18

Starting on Monday, March 18th, one of Metro and CalTrans contractors, Traffic Loops, will be working on installing some new equipment at the intersection of Huntington and Myrtle and anticipate finishing work by the end of the week.  This equipment installation is part of the I-210 Connected Corridors Pilot Project that the City of Monrovia is partnering with CalTrans, Metro, LA County, City of Pasadena, City of Arcadia and the City of Duarte.  Traffic Loops will be installing new conduit along with a camera detection system.  This equipment will be used as part of a pilot project that has an ultimate goal of trying to improve traffic flow during major traffic incidents along the I-210 corridor.

During the week of March 18th, the intersection of Huntington and Myrtle will be on a timer rather than a detection loop system.  If you have any questions please feel free to call Public Works at 626-932-5575.

Southern California Edison Engaged in Ongoing Repair Work Here in Town for the Remainder of 2019

Southern California Edison has been coordinating with City staff on upcoming work that will take place over the next 9 months.  SCE staff has identified a number of needed repairs to their infrastructure citywide, ranging from replacing conductors, cross-arms, cabling, anchoring poles, pole replacement, or simple miscellaneous repairs.  Each of these needed repairs has been given a priority level designation (1-3) with 3 being the highest priority repair.

To date, SCE staff has identified approximately 200 Tier 3 repairs that need to be completed by May 31.  In addition to the Tier 3 repairs, SCE staff has identified an additional 350 Tier 2 and Tier 1 repairs that need to be completed by the end of the year (December 31).  In total, that means SCE will be repairing approximately 550 various pieces of equipment throughout town over the next 9 months.  Public Works staff is coordinating with SCE staff on permitting, scheduling of work, and ultimately coordination that helps SCE complete their interim and final completion dates.  Because of the volume of work, this will likely mean that SCE will be working seven days a week between now and the end of May to meet the first interim completion date for Tier 3 repairs.

SCE will be sending out mailers, door knockers, and other notification letters to the residents in the impacted areas in advance of the work.  Additional notification will be required when SCE needs access to private property as well as additional notification that results in any temporary power outages.  If there are any questions regarding SCE’s activity, please visit SCE’s website. If you have any questions or concerns, please feel free to call Public Works at (626) 932-5575.
