Project Background

In May 2020, the Town Council adopted a "Worst-First" pavement repair approach, prioritizing streets designated as being "Very Poor" (a Pavement Condition Index, or PCI, range of 0-25) and "Poor" (a PCI ranging from 26-50) pavement condition.  A Town Council Goal for 2022 is to implement the 2021 Pavement Management Program, including the design for the 2022-2024 "Worst First" Pavement Rehabilitation Project and the Annual Pavement Repair Project.  

The scope of the 2022-2024 Pavement Rehabilitation Projects aims to rehabilitate residential and collector streets with a PCI of 50 or less in 2024.  Project scopes will include pavement rehabilitation, storm repairs, limited curb, and gutter repairs, and installing/upgrading substandard curb ramps. The Town Council awarded the design contract to Harris and Associates on October 27, 2021.   

On August 4, 2022, the Town awarded DeSilva Gates Construction (Dublin, CA) a construction contract for the 2022 Pavement Rehabilitation Project (CIP 22-401). The 2022 Pavement Rehabilitation Project started construction this Fall of 2022.  For more information on what to expect, please see the Pavement Management Program FAQ sheet below. DeSilva Gates Construction's general construction schedule, not adjusted for weather delays and other factors to be as follows:

The above schedule is subject to change without notice. The schedule does not account for delays for additional work, weather, equipment breakdowns, utility conflicts, and other issues. For a more detailed schedule, including work locations, please see the 3-week look ahead schedule posted below.

2022 Pavement Rehabilitation Project

The design street list for the 2022 Pavement Rehabilitation project is below.  These streets were chosen based on their PCI as well as preliminary field investigation.  Treatments will vary from microsurfacing, cape seal, and overlay.  The streets listed in the table below is subject to change during design due to underground conflicts, budgets, construction bid proposal, etc.  The final list will be made available when the Town Council awards the construction contract.  

NOTE: The street list is subject to change.

Concrete Repair

During design, the concrete curb, gutter, and sidewalk abutting private properties were inspected in preparation for the street rehabilitation projects. Portions of the sidewalk, curb, and gutter were marked accordingly for repairs. Sidewalk inspection is based on criteria from Caltrans and Federal Americans with Disabilities Act (ADA) regulations and standards. The maximum vertical surface separation between concrete surfaces is ¼ inch, and the maximum openings (such as cracks and holes) in the surface is ½ inch, but other issues may be cited that exceed Federal regulations.

Curbs and gutters capture runoff from the street and convey the water to storm drain inlets and other capture points. The new pavement surfaces will be paved to match the existing curb and gutter. Curb and gutter that is sunken or raised can cause ponding. Cracks in the concrete cause water intrusion underneath the new pavement, accelerating pavement deterioration over time, will require repairs.

 Property Owner Responsibilities To Maintain Curb, Gutter, Sidewalks, and Other Improvements

The Town of Moraga does not maintain curbs, gutters, sidewalks, pathways, trees, shrubs, hedges, and other landscaping or improvements in what the Town defines as the sidewalk area from the roadway edge to the private property line, which is considered to be part of the Public Right-of-Way (ROW). This policy established from the Moraga Municipal Code has been in place since 1977 for sidewalks and, in its existing form, has been in place since 1990, which expanded responsibility limits outwards to include gutters and parking strips. The property owner maintenance responsibility of improvements along their properties is consistent with other local jurisdictions, including Contra Costa County and the Cities of Lafayette and Orinda, to name a few.

Per the Moraga Municipal Code (MMC) Section 12.04.010 A - Property owner(s) are responsible for repairing and maintaining sidewalk area. A link to the MMC is as follows: https://library.municode.com/ca/moraga/codes/municipal_code. The relevant section is noted below:

 "12.04.010 A. The owner of a parcel of real property which fronts on any portion of a sidewalk area between the property line of the parcel and the street line, including a parking strip and curb, is responsible for the repair and maintenance of the sidewalk area and shall pay the cost and expense of repair and maintenance."

 The "sidewalk area" is measured from the street pavement edge (including the parking strip and/or curb/gutter if present) to the private property line, regardless of an actual paved sidewalk being present.

 Can the limits of the marked-out concrete areas be reduced?

Property owners are being asked to replace sections of curb and gutter from score mark joint to score mark joint as this is the Town standard for replacing concrete. In limited cases that do not cause drainage or ADA compliance issues, Engineering staff may be able to approve a reduction in the portion of needed concrete replacement. In most cases, unfortunately, it is not possible to reduce the amount of concrete replacement. Please contact the Engineering staff if you would like to review the marked replacement limits.

Options for concrete repair:

1. Short-term repair - Grind, cut, or seal flush any gaps or offsets to be flush with adjoining concrete within certain limits. Please confer with the Town Public Works Engineering staff to determine if this is an appropriate repair solution for your situation. If it is determined to be an appropriate solution, the property owner will have to hire a licensed contractor to perform or complete the work themselves. Sealing gaps and offset will filler or sealant material is not an approved long-term repair method due to concerns regarding ADA compliance, long-term stability (particularly for curbs/gutters that are subject to the weight of vehicles), and concerns of materials or pollutants entering the storm drainage system. Please consult the Engineering staff for possible exceptions. Please see the "Hiring a licensed contractor or complete work themselves" section below for requirements.
2. Remove and replace – Removing the marked-out area and replacing it with a new curb gutter and/or sidewalk. The property owner can hire a licensed contractor to perform the work, complete the work themselves or enter into an agreement with the Town for the property owner to pay for the replacement of concrete utilizing the Town's Contractor to complete the work. The use of the Town's contractor is limited to the contractor accepting this additional work (outside their original contract work scope) at their original bid item pricing.

Hiring a Licensed Contractor or Complete the Work Themselves:

Property owners can complete the repairs by hiring a licensed contractor or completing the work themselves. The work requires an Encroachment Permit as a cost to the property owners to ensure all work is completed per Town standards. The encroachment permit form can be found at www.moraga.ca.us/encroachmentpermits. For questions or additional information, contact the encroachment permit staff at (925) 888-7041 or via email at encrpermit@moraga.ca.us. All repairs must be completed by February 1, 2023, to prevent conflicts with the Town's contractor street work and to allow for abatement work to occur. 

The Town reserves the right to complete the repairs and seek reimbursement, including all administration costs.

Utilizing the Town's contractor:

The Town understands the challenges in meeting this deadline, including the short time frame to perform repairs; difficulty in finding reasonably priced contractors; the unplanned time associated with retaining a contractor and permits; and the costs of the repairs. To assist property owners, the Town developed the option to address the quick time frame necessary for completing the work; to ease the property owners' burden of retaining contractors and managing the work; and, in some cases, provide a more cost-effective alternative.

Property owners can enter into an agreement with the Town to utilize the Town Contractor to complete the concrete curb, gutter, and sidewalk repairs. The Town has negotiated an all-inclusive price for the repair work that includes site inspections/permits, construction insurance, and staff administration costs. The following lists the pass-thru construction costs based on the lowest, responsive, and responsible construction bid received on August 2, 2022, from DeSilva Gates Construction, for various items related to the replacement of underdrains, curbs/gutters, and/or sidewalks: 

• Remove and replace curb and gutter                            $160 per linear foot
• Remove and replace sidewalk                                         $30 per square foot
• Remove and replace underdrain                                    $1,000 each

 If you have received an agreement and elect this option, please return it by the deadline listed on the agreement to guarantee the work will be included. If it is passed the deadline, please contact the Town's Project Manager to check the status of the concrete work and if the Town's contractor is willing to complete additional work.
