Monrovia Renewal North Area Road Work Construction Activities Set To Continue, With Major Street Work Now Underway!

Street reconstruction activities are underway in the North Section of the City’s Monrovia Renewal Project.  Pulverizing activities are being completed on the streets that are scheduled for a full 4” Reconstruction.  The planned street improvements as a part of Monrovia Renewal include 4” Full Reconstruction, 2” Asphalt Overlay, and Microsurfacing totaling nearly 2.3 million square feet of street improvements.  As this is the largest section of Monrovia Renewal, street improvements will continue between now and August 2019.  For purposes of managing a project of this scale, Sully-Miller is conducting the paving work in phases and each area will receive a subsequent schedule and notification prior to work taking place in their immediate area.  If your street is not listed in the information below, it will be coming shortly!

Monrovia Renewal Phase 1

Work will continue in the North Section and will include:

  • Water Tie-Ins
    • Streets include: Greystone Avenue, Prospect Avenue and Norumbega Avenue
    • These activities may require water shut downs to complete the work. All impacted customers will be notified at least 24 hours in advance of water shut down
    • The schedule for the remaining street areas will be shared prior to work taking place in those areas.
  • Saw cutting and removals
    • Streets include: Westside of Highland Place, Northside of Franklin Place and Encinitas Avenue
  • Slot Patching / Street Reconstruction
    • Streets include: Melrose Avenue, Highland Place and Encinitas Avenue
    • As outlined in the step by step overview below, these streets will be:
      • Paving: will continue through this coming week
      • Concrete pouring: will continue for the next two weeks

Work will continue to focus on concrete improvements as well as water and sewer work. Street construction and paving activities are set to resume around the end of July!

Overview of Street Reconstruction Process and Impacts:

As part of the complete reconstruction, the streets will be pulverized to dirt in a multiple step process:

  1. Day 1: A machine will pulverize the existing roadway surface 10" deep to create new base material. This dirt material will be rolled and compacted to be driven on.
  2. Day 2: A couple of days later, crews will return with large machines to remove 4" of the pulverized material. This dirt material will, again, be rolled and compacted to be driven on.
  3. Days 3 & 4: After the material has been removed, crews will return to pave new asphalt on the street. Paving will be completed in 2 - 2" sections on two different days. We anticipate approximately 2 weeks between the initial layer of asphalt being paved and the final cap paving.

*Although this process will take approximately 4 working days for each street section, there might be downtime between each phase meaning that the entire process might take a couple of weeks.

During this process, it is important to remember:

  • Although many streets will be turned to dirt, vehicles may still access the street (except for intermittent periods during active construction
  • There will be parking restrictions in place during work hours however vehicles will be permitted to park on the street at the end of working days. PLEASE ADHERE TO ALL POSTED PARKING RESTRICTIONS.
  • Driveways will be accessible every night; however access may be limited during daytime work activities.
  • Pulverized streets may remain dirt streets for up to three weeks.

The project area map below indicates the specific road work that will take place on each street. More details on the upcoming road work for Monrovia Renewal will be included in future updates, including dates and specific street locations. We appreciate your patience and support while we work to execute these improvements throughout our community!

Suspension of Street Sweeping Enforcement in North Section Construction Area as Monrovia Renewal Work Continues

As we have embarked on Monrovia Renewal North area improvements and have assessed the extensive nature of the construction activity, the City has measured the need to suspend traditional street sweeping operations and enforcement while construction is underway. Beginning Monday, June 17, posted street sweeping restrictions will not be enforced in the current work area, specifically, the portion of the City that is north of and including Hillcrest Boulevard, Grand Avenue, and Greystone Avenue.

While construction activity continues in this section, residents are advised to adhere to all posted construction parking signs! The suspension of enforcement applies only to street sweeping restrictions; all other parking and vehicle code sections will remain enforced.

The suspension of citations related to street sweeping will take into effect June 17, 2019 and will continue through August 31, 2019.

We appreciate all of your patience as we continue Monrovia Renewal. Should you have any questions or concerns please do not hesitate to call (626) 932-5575 or monroviarenewal@ci.monrovia.ca.us.


Monrovia Renewal South Section Project Completion Plan Developed - City Working to Finalize Updated Schedule with New Contractor, Work Set to Begin Within the Next Few Weeks!

 As we’ve been sharing for the past several weeks, we have had a bit of a delay in completing all of the planned work located in the South Section of Monrovia Renewal.  For reference, the South Section of our overall Citywide infrastructure improvement plan includes the entire portion of the City located south of the I-210 Freeway, and during the past few months, the City has been working to develop an alternative plan to complete the street repair work for that particular section of town.  We had been working with one contractor (Sequel Contractors), however, for a variety of coordination and scheduling issues, here at the City, we have had to develop an alternative plan in order to finish the identified work, which includes (among other things) around 1.35 million square feet of street improvements!

Well… after some delay, we’re delighted to share that we’ve finalized a plan to complete the remaining work, as the City has formally engaged another contractor to finish out our South Section upgrades!  We spent significant time this past week working through project details with our new contractor (Sully-Miller), and we expect to have a full run-down – including an updated work schedule – ready to distribute within the next week or two.  In addition, based on our discussions to date, we do anticipate that the construction work in the South Section will begin in early August!

A map highlighting the streets that still require additional work is included below.  In addition, all of us here at the City appreciate the patience that the community has had with us as we’ve worked through executing our signature capital improvement initiative.  Monrovia Renewal has certainly been messy, but the end result will be upgraded infrastructure throughout our community!

Of course, if you have any questions or concerns, please contact a member of our project team (626) 932-5575 or at monroviarenewal@ci.monrovia.ca.us.

Monrova Renewal Street Repairs - South Section


Initial City Entryway Improvements at Huntington Drive / 5th Avenue Set to Take Place in Mid-July, Work will Involve Upgrading the Southeast Entryway Corner to Monrovia

During the past year, staff has been engaged in coordinating a capital improvement project that will result in a reconfiguration of the intersection at 5th Avenue / Huntington Drive.  The planned improvements are funded through a variety of different sources, and the overall elements associated with the enhancements include:

  • An initial reconfiguration of the Southeast entryway corner of Huntington Drive / 5th Avenue to facilitate future phases of the improvements
  • Installation of a new entryway monument at the location (along with the corresponding entryway monuments / public art along the entire stretch of Huntington Drive in Monrovia), along with new landscaping
  • Widening Huntington Drive at 5th Avenue in Monrovia to facilitate improved traffic flow at the location
  • Installation of new traffic signals at the Huntington Drive / 5th Avenue intersection to facilitate protected left turn movements in all directions

Given the coordination that has occurred to date, the first phase of the planned improvements – reconfiguring and widening the southwest entryway corner of Huntington Drive / 5th Avenue to facilitate all of the other enhancements – is scheduled to begin in a few weeks in mid-July.  As part of that work, the existing entryway monument will need to be removed, and staff is in the process of coordinating that removal process now.

In order for the reconfiguration of the southwest entryway corner on Huntington Drive to proceed, the City needs to expand the area of this particular corner to facilitate all of the planned future work.  To accomplish this task, the City’s contractor will work to expand the covering over an existing underground pedestrian trail that travels below Huntington Drive, along the Santa Anita wash. 

Utilizing some of the existing structure, a box culvert will be built in the wash that will include a traffic rated deck to match the existing grade of the corner.  This will add more than 100 additional square feet of space to this corner and will form the basis for the eventual installation of new welcome monuments, improved landscaping, new traffic signals, and pedestrian space.

This initial work is slated to begin in mid-July, and as part of the construction activity, we will be removing the existing entryway monument (and don’t worry… the City will be saving the monument!).  In addition, existing fencing and landscaping will also be removed as a part of preparing the corner for work.  Once everything is cleared, City contractors will begin building the structural support for the expansion, which will take place below the road along the pedestrian trail.  Once that is complete, contractors will focus on constructing the deck at grade.

The overall work will take around 4-weeks to complete, and although the work will take place out of the roadway, there may be times when contractors will be encroaching onto Fifth Avenue and Huntington Drive during the construction activity.  Of course, in those instances, proper and thorough traffic control will be installed to ensure that the work zone is safe at all times.  In addition, due to the potential traffic delays, our team has been in touch with our counterparts at the City of Arcadia to advise of potential impacts.  Finally, we ask all motorists and pedestrians in the area to be please be safe and expect delays.

Of note, given the visibility of the entryway monument at 5th Avenue / Huntington Drive for Monrovia, staff is planning to coordinate a City Council Study Session to review the planned improvements at the intersection location on July 16.  At that meeting, we’ll describe all of the planned work in greater detail, including a review of design concepts for the newly planned entryway monument.  The new entryway monument art components that we’ve been developing have been inspired by the Station Square art / signage program, and we look forward to sharing these new design concepts with everyone once they are vetted a bit further.  However… as a sneak peak of where we’re headed… see the draft rendering below!

In the meantime, if you have any questions about this matter, please call Public Works at (626) 932-5575 or email PWcomments@ci.monrovia.ca.us.

Improvements to Intersection of Huntington & Mayflower Completed on June 23 - Staff to Continue to Monitor Conditions at Intersection

On June 23, Los Angeles County Public Works Crews implemented improvements to the operations of the intersection at Huntington Drive and Myrtle Avenue.  The improvements include a revised striping and signage plan as well as changes to the traffic signal operations, all of which will:

  • Close the gap in the median on Mayflower Avenue to prevent left turn movements
  • Changing the signal operations to a "Split Phase" whereby traffic on Mayflower Avenue will cycle with all northbound traffic at one and then all southbound traffic that they are not on the same cycle; this will improve left turn movements for vehicles traveling both directions on Mayflower Avenue.
  • Implement new lane configurations for the Northbound traffic on Mayflower Avenue, including:
    • Number 1 Lane: Left Turn only
    • Number 2 Lane: Left Turn or Straight/Through
    • Number 3 Lane: Right Turn only

Staff worked with Los Angeles County Public Works, over the last several months, to review the conditions at this intersection and design the implemented improvements. The primary concern that was hears was issues with motorists on northbound Mayflower Avenue as they approach Huntington Drive. This area has been known to back up severely due to capacity of left turns at Huntington Drive, the left turns of vehicles into and out of the shopping center on the East side of Mayflower. These improvements will increase the throughput of vehicles on northbound Mayflower to alleviate these conditions.

Public Works and Engineering staff will continue to monitor conditions at this intersection to ensure that the improvements are operating as designed. If necessary, minor changes and improvements will be implemented if necessary. Please contact Public Works if you have any questions or concerns.


Annual Citywide Sewer Cleaning Program Set to Begin, With 200,000 Linear Feet of Sewer Lines Set to be Cleaned by July

We wanted to let everyone know that this week, the City started our annual sewer maintenance program, and our team has been deployed in concert with a private contractor (Houston Harris) to coordinate an initial cleaning of ~250,000 linear feet of sewer lines throughout the City.  And just in case you didn’t know… 250,000 linear feet is equivalent to nearly 47 miles!

Overall, the City’s sanitary sewer system contains approximately 92 miles of sewer line comprised of various sizes (ranging from 6” to 24” diameters) and materials (including iron, steel, and vitrified clay).  Given that quantity of sewer lines, our sewer maintenance program includes the cleaning of around 250,000 linear feet of sewer pipelines annually.  The crews in the field now are using a method known as hydro jetting to clear any possible sewer blockages, and additionally, our team will be coordinating the inspection of the sewer lines utilizing closed circuit video.  Other maintenance activities include root removal and pest control programs.

During the next few months, we will be coordinating this sewer maintenance work, and if you see large equipment located throughout town at sewer manholes… rest assured, our team is hard at work keeping the brown in the round!


Southern California Edison Planning Electrical System Improvements That Will Impact Portions of Myrtle, Walnut and Primrose

Construction crews and inspectors from Southern California Edison (SCE) are coordinating a significant electrical system undergrounding improvement project that will impact the area of Myrtle Avenue, Primrose Avenue, and Walnut Avenue. The construction work, which is anticipated to last 6 – 8 weeks, will involve trenching and excavating portions of the 800 block of South Myrtle Avenue, along with portions of Walnut Avenue adjacent west of Myrtle Avenue, in order to install new conduits, ducts, and other underground structures to reroute existing SCE infrastructure.  Of particular note, as part of the work, SCE will need to have a trench cut across Myrtle Avenue, which will require robust traffic control efforts.

Work began on June 17 with crews trenching and installing conduit within the roadway to connect all of the underground vaults and facilities that were previously installed.  Work began on Primrose north to Walnut and down Walnut eastbound to Myrtle.  Work is taking place along one side of the street so through traffic will be available; motorists are advised to be cautious when traveling through work areas.  All businesses and residences in the area will be accessible at all times.  Please contact Public Works with any questions about the work progress and schedule!
