Sequel Contractors have begun preparations related to the street improvement component of Monrovia Renewal in the South section.  Various improvements are planned depending on the current street condition including slurry seal, asphalt overlay activities, micro-surfacing, and complete street reconstruction.

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

Please see the project area map for the specific street treatments in your area. You will find further details related to the three street treatments and possible impacts below.

Monrovia Renewal South Section Street Work


Southwest / Southwest Sections of Monrovia Renewal Getting Newly-Painted Curb Addresses

As a follow-up to the Monrovia Renewal improvements completed in the Southwest and Southeast sections of the City, house numbers needed to be re-painted on the streets where curb and gutters had been removed and replaced. These two sections had approximately 900 address needed this service and to complete this work by a contractor would have been a costly endeavor.

City staff proposed a unique solution to this taxing project. Staff proposed working with a long time partner and non-profit, Care for the Children to pay them directly to complete the work at a significantly lower rate. Care for the Children has long served our community by painting house numbers on curbs and are the subject area experts in this field. Although, typically this organization collects donations for curb painting, the City developed a plan to re-paint addresses, without solicitation or donation. This cost saving plan allowed for the replacement of curb addresses at a lower rate, while also benefiting Care for the Children.

In the coming weeks, the traditional voluntary donation curb painting program will resume, on streets where curb addresses were not impacted by Monrovia Renewal! Many thanks to the members of our City team in the Public Works Division for their assistance in developing this innovative solution.

Basement Repairs at the Historic Museum Have Begun

During the past year, staff has been assessing the situation at the Monrovia Historic Museum, which has been subject to repeated instances of flooding in the basement. Based on our assessment to date, staff has developed a multi-pronged approach to address the ongoing flooding and moisture issues at the Museum, with the planned maintenance activities set to begin on October 8, 2018. As part of our repair efforts, staff has coordinated a number of repair enhancements at the Museum, to include installation of a dry well, new hardscape, a permanent dehumidifier, and interior wall treatments at the museum. An overview of each phase of the work is outlined below:

  • Dry Well Installation
    • The installation of a new dry well is planned at the northeast section of the building.
    • Construction work should take no more than 2 - 3 days, and the work will only p,act the lawn in front of the Museum.
    • The dry well has been designed in this location to act as a collector for any water in the exterior of the building, and staff will be on site supervising the entire project.
    • The dry well installations is tentatively scheduled to take place the week of October 8, 2018.
  • Hardscape Improvements
    • As part of the enhancements, we are looking to make hardscape improvements to the landscaped area on the southwest side of the building.
    • The hardscape plan also includes creating a new concrete curb around the basement door on the northeast side of the building.
    • These hardscape improvements are tentatively scheduled to take place in late-October / early-November 2018.
  • Permanent Dehumidifier
    • Based on the issues that are occurring at the Museum, we are also looking to install a permanent dehumidifier in the basement that is properly connected to a drainage system.
    • Given the experience that we have had in the basement during the past several years, it was determined that an ongoing dehumidifier treatment system would be needed to manage the moisture.
    • This work is scheduled to take place in November 2018.
  • Interior Wall Treatment
    • The final maintenance treatment at the Museum will involve applying a new sealant to all of the walls in the basement, and then repainting the area.
    • This work is scheduled to take place in November / December 2018.

Staff developed this suite of maintenance activities after much consideration, and the proposed workplan will go a long ways towards finally resolving the ongoing moisture related issues we have been experiencing at the Museum. If you should have any questions about this plan, please call the Public Works Division at (626) 932-5575.
