South Section Infrastructure Improvements to Break Ground in April 2018!

The Monrovia Renewal South Section Infrastructure Improvements Project includes the area of the City that is located below the 210 Freeway. The scope of work includes the removal and replacement of concrete sidewalk, curb and gutter, and driveway approaches, the replacement of water service lines, sewer lining and point repairs at various locations, pipeline and valve improvements to the City's water system, installation of drainage improvements, and a complete battery of roadway improvements.

The three stages of construction will follow the same outline as the Northwest section. However, for the South project section, there will be an additional bit of work involved to install a sidewalk, trees, shrubs and irrigation on the north side of Duarte Avenue, east of California Avenue. Find your area on the map below to see what improvements are planned for your neighborhood!

Prior to construction, the contractor will provide a number of notices and postings in the impacted area. If you have any questions or concerns regarding the construction activities, please contact Public Works at (626) 932-5575.

Renewal - South Section

Northwest Section Construction Continues!

The City continues to progress through the Northwest Section of Monrovia Renewal, which is a multi-year infrastructure initiative aimed at making priority repairs to the City's water and sewer pipelines, water facilities, streets, sidewalks, curbs and gutters. Work is presently underway in the Northwest project area, which includes the section of the City bound by Myrtle Avenue to the east, the City limits to the west, Hillcrest Boulevard to the north and Colorado Boulevard to the south.

Three Stages of Construction Work:

There is a variety of work taking place, including underground utilities, concrete construction, and street construction. The work is being executed in stages to progress efficiently while minimizing impacts to the nearby residents and businesses. Work typically progresses in the following manner:

  1. All necessary underground work related to water and sewer pipelines.
  2. Repairs and replacements of curbs, gutters and driveway approaches.
  3. Street repairs and rehabilitation. Streets scheduled for repairs may receive one of three treatments: slurry seal which is a new sealant/top coat; a grind and overlay, which removes the top two inches of asphalt pavement and replaces it with new surface, or full reconstruction which means the street is removed down to dirt and fully reconstructed.

Oakglade Reservoir Upgrade Project

The Oakglade Reservoir Upgrade Project is a major water facility project that will replace and expand the City's existing reservoir located at 733 Oakglade Drive, as part of Monrovia Renewal.  The Oakglade Reservoir was initially built in the late 1800s and was one of the original water reservoirs for Monrovia.  However, over time, the reservoir has developed excessive leaks and cracks.  Given the growth of our community, the tank is currently too small to handle the increased water capacity needs of the City.Oakglade Reservoir Entrance

To that end, as part of the Monrovia Renewal project, the City is looking to replace the existing Oakglade Reservoir, which has a capacity of 900,000 gallons, with a brand new 1.5-million-gallon reservoir.  This will increase our supply capacity by 67%, while also improving emergency and operational water storage requirements in the area.

While the improvement project is important, staff has recognized that the overall initiative will be very invasive for the residents that live off of Oakglade Drive and Ridgeside Drive.  Based on our current project schedule, we anticipate that we will be ready to begin construction in late January/February 2018.

Pursuant to the California Environmental Quality Act (CEQA) an Initial Study has been prepared for the proposed project, which determined there could be significant impacts however, through the incorporation of mitigation measures, these impacts would be reduced to less than significant levels.  Impacts to all other study areas were found to be less than significant.  A Mitigated Negative Declaration (MND) has been prepared. The public review period for the Initial Study and Draft MND took place October 9-30, 2017.

Sidewalks Repairs Complete in Northwest Section of Monrovia Renewal - Now Underway in South Section

During the past year, the City has been working with Precision Concrete Cutting to assess the City’s entire sidewalk system - about 125 miles of sidewalk! Their Sidewalk Master Plan reported the condition of all our sidewalks, and the City has created a plan to address these issues. Some damaged sections of sidewalk will need to be removed and replaced, whereas other sections can be repaired using Precision's patented sidewalk cutting technology to remove sidewalk lifts up to 2 inches in height and address cracks and other imperfections. This technique has minimal impact and results in a cost savings of up to 84% over replacing the whole panel! 

Precision has completed more than 7,000 sidewalk repairs in the Southwest and Southeast Sections (area between Colorado Boulevard and the I-210 Freeway) of Monrovia Renewal over the past year.

Precision's crews have completed sidewalk repairs in the Northwest Section of Monrovia Renewal - the area west of Myrtle Avenue between Colorado and Hillcrest Boulevards - to reduce trip hazards and other sidewalk issues. They are now working in the South Section - the area south of the 210 freeway to City limits.

Note that there are no roadway impacts while these repairs are taking place, as Precision uses a mobile cart on the sidewalk area itself. Cones will be placed in the work area. Pedestrians should use caution when moving through the area and cross to the other side of the street or take an alternate route where possible.

If you have any questions, please contact Public Works 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.

The City’s sewer maintenance contractor, National Plant Services, is currently working in the Northwest segment of Monrovia Renewal, which is the area between Colorado Boulevard and Hillcrest Boulevard, east of Myrtle Avenue extending to the City’s western limits.

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.

After we complete work in the Northwest section, additional sewer maintenance and CCTV work will occur in the South section to prepare for repairs that will take place starting in Winter 2017.
