Monrovia Renewal South Section Infrastructure Improvements - Work for Week of May 7, 2018

The Monrovia Renewal South Section project has begun! Last week, Sequel contractors, Inc. began infrastructure improvements in the South Section, which includes the entire area within the City Limits below the 210-Freeway. This week, the following work is set to take place:

  • Removal and replacement of sidewalk, curb and gutter, and driveway approaches in the area of South Myrtle, Peck Road and the streets in between
  • Removal and replacement of identified water service lines on Monrovista Avenue, Duarte Road and Evergreen Avenue
  • Dry Well installation on Atara Street (see more information about this particular project below)

As Sequel Contractors works their way through the South Section, the team will distribute advanced notices to residents and business owners where the work will be taking place. The team has also posted parking restrictions, and marked out streets, sidewalks, curbs and gutter, and driveways. 

Trees Identified to be Removed and Replaced in the South Section

While the project team was conducting survey work related to Monrovia Renewal in the South Section, a number of trees were identified as being problematic due to their health and condition as well as the impact they are having on the infrastructure. As the team as demonstrated in other sections, we strive to protect and maintain trees, even if it means designing the improvements around them. Before going to those lengths, the threes are assessed and evaluated for their health and condition. In the case where the tree's condition and health are struggling, the decision might be made to remove the tree.

In areas of the South, specifically along Myrtle Avenue and Peck Road, there are a number of liquidambar trees that are notorious for causing damage to the infrastructure and are in failing health. A number of these trees have been topped to prevent them from interfering with the utility lines, and as such, they are in declining condition.

The project team has identified a number of these trees to be removed in order to replace and improve the sidewalks in this area. The team is coordinating with the contractor and will notify the adjacent residents or businesses of the plan related to the trees.

As part of the replacement of the sidewalk, the tree wells will be left intact so that the new trees can be planted back in their place. The Field Services team is working to identify sustainable 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.

Installation of Drywell Improvements on Atara, Diamond, and El Dorado to Begin in South Section on May 7

As a component of the South Section, the project team developed some opportunities to better manage stormwater by infiltrating it into the ground utilizing new drywells and storm drain infrastructure. These efforts will help mitigate any run-off issues in the area and will aid in the preservation of the pavement by diverting the water into the proper drainage infrastructure.

The construction of drywells is quite different from the other activities that have been conducted as part of Monrovia Renewal as it will require drilling (using a rig that is about 30' tall) to about 50' below the ground! Water will be collected in new catch basins that will be installed on the streets and connected to pipeline to these drywells. Water will feed into the drywell and be infiltrated back into the ground. Below are some photos of a typical dry well construction site including the equipment used as a completed dry well and storm drain system.

Given the unique nature of this work, there will be some additional impacts to the surrounding residents and businesses including noise and vibrations. There will be intermittent closures on the street while the work is taking place during the day, but all residents will be able to access their street and driveways at the end of each day. The work will take about (5) days per location to drill and install the drywell. Crews will return at a later time to complete the construction of the catch basins and installation of the pipelines.

This week, drywells will be installed on Atara Street. Following the installation on Atara Street, dry wells will also be installed on:

  • Diamond Street between Alamitas Avenue and Mayflower Avenue
  • El Dorado Street between 5th Avenue and Encino Avenue

A sample outreach flyer with more information related to the drywells that will be distributed to the residents in the affected areas is attached to this report for your reference.

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.

For additional project information, please contact the Public Works Division at (626) 932-5575.

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.
