RECOMMENDATION
Recommendation
That Council adopts the attached resolution (Attachment I) and approves the plans and specifications for the FY 2016 Pavement Rehabilitation Project, and calls for bids to be received on April 26, 2016.
Body
BACKGROUND
This year’s Pavement Rehabilitation Project calls for the rehabilitation of fifty-eight city street sections. Please see Attachment II for the list of streets. The proposed improvements will repair failed pavement sections and improve the riding surface of the streets.
DISCUSSION
The approval of Measure C has made additional funds available to the City’s Street Pavement Management Program, which is over and above funds the City receives annually from Measure B, Measure BB, Gas Tax, Vehicle Registration Fees, and funds from the Street System Improvements Fund. This has allowed the City to engage in the largest street pavement improvement program in the City’s recent history, and provided a one-time opportunity to improve more of the City’s street network. The City’s Pavement Management Program falls into two main categories: 1) Street Pavement Preventative Maintenance & Resurfacing Program, which is presented in a separate report, and 2) Street Pavement Rehabilitation & Reconstruction Program, presented in this report.
The Pavement Rehabilitation & Reconstruction Program involves repairing severely deteriorated streets to return them to acceptable pavement condition standards and may involve one of three types of treatments: 1) standard overlay of the existing street pavement with new Hot Mix Asphalt Concrete; 2) Cold-In-Place Recycling (CIR), which involves pulverization of the top layer of existing asphalt concrete pavement, treating the resulting aggregates with chemicals and placing the resulting material back followed by a new layer of Hot Mix Asphalt Concrete; or 3) Full Depth Reclamation (FDR), where the entire pavement section down to the subgrade is pulverized, reusing the pulverized aggregate material as a compacted and stabilized base course that is capped with new Hot Mix Asphalt Concrete.
Over recent years and consistent with Council’s objectives in the use of environmentally friendly products, and reduction of carbon footprint, engineering staff has moved toward the use of environmentally friendly materials and methods of the pavement construction. Ironically, these methods have also proven to reduce cost and time. The pavement methods described above all involve reusing the existing pavement. In addition to the cost savings from not off hauling the old asphalt concrete material, the reduced number of truck trips also reduces carbon footprint. Staff is currently reviewing another method of pavement construction, called Hot In Place Recycling (HIR), which involves heating the existing deteriorated pavement in-place, mixing rejuvenating chemicals, and placing the pavement back as a smooth rideable surface.
The FY 2016 Pavement Rehabilitation & Reconstruction project involves fifty-eight street sections. Please see Attachment II for the list of streets included in this project. The identified streets were selected based on staff’s analysis of the Pavement Condition Indices (PCI) identified through the City’s computerized Pavement Managements Program (PMP), field examination, and the functional classification of each street. This project will cover fifteen lane-miles of streets. Overall, the City is responsible for the maintenance of 657 lane-miles of roadway.
The rather large number of streets included in this year’s program, as compared to prior years, is made possible by the infusion of additional funds from Measure C. This one-time increase in funding, which seriously improves current pavement conditions, still does not address many areas of the City; and will not significantly decrease the street maintenance backlog, which stood at over $100 million in 2015 and is expected to grow according to the February 25, 2014 Hayward Pavement Management System Update Report submitted to the Metropolitan Transportation Commission (MTC).
According to this report, the City will need to spend an average of $17 million per year over the next five years in order to maintain the City’s current network PCI of sixty-seven. In order to increase the PCI by five points or bring the street network PCI to seventy-two, the City will need to spend an average of $24 million per year over the next five years. To put into perspective, an area such as the Old Hayward Highlands Area (OHHA) neighborhood, which has very poor street infrastructure, would require basic roadway reconstruction (i.e., excluding concrete curbs, and sidewalks, or other mitigation works) at a cost of over $12 million just to bring streets in this neighborhood to current standards, according to a study performed by a city consultant, MMS Design Associates in 2007 (cost estimates prorated to 2015 dollars). The street infrastructure in the OHHA Neighborhood, in many respects, is unique given its history and the fact that many properties in this neighborhood have a Deferred Improvement Agreement, which make the property owners responsible for the cost of improvements at their frontage, including the grant of right of way.
As requested, staff will revisit this issue with Council at a Work Session to present current maintenance work in OHHA, and discuss ongoing efforts to identify funding sources to address the overwhelming maintenance and repair/replacement backlog in that area in a manner that will not negatively impact the overall City Pavement Rehabilitation program throughout the City.
This project is categorically exempt under Section 15301(c) of the California Environmental Quality Act Guidelines for the operation, repair, maintenance, or minor alteration of existing facilities.
FISCAL IMPACT
The estimated project costs are as follows:
The Recommended FY 2016 Capital Improvement Program includes funding from various sources as follows:
PUBLIC CONTACT
Because of the large number of street sections to be improved throughout the city, staff has undertaken careful planning to prevent traffic congestion and limit inconvenience to the community. To this end, a staging plan has been developed that divides the city into three construction zones, with the contractor required to complete work in one zone before moving to another zone. Also, the contractor will be required to allow local traffic at all times, and to keep side streets open when working on a given street to allow residents places to park that are not too far from their homes.
Immediately after the construction contract is awarded, a preliminary notice explaining the project will be posted and distributed to all residents and businesses along the affected streets. After the construction work has been scheduled, signs on barricades will be posted seventy-two hours prior to commencement of work indicating the date and time of work for each street. Residents will be advised to park their vehicles on side streets outside of the work area during the period when the streets are being treated.
COMPLETE STREETS
The existing bicycle facilities, sidewalk, and street lighting will be maintained during construction. This project will reconstruct existing curb ramps that are not ADA compliant. Improvements along these streets are consistent with the City’s adopted Complete Streets Policy, which ensures that consideration is given to all users of the street, including pedestrians, bicyclists, transit, senior citizens and school children, in addition to vehicular traffic.
