                                      MEMORANDUM

Date:            Tuesday, September 27, 2011

To:              Bryan H. Montgomery, City Manager

From:            Jason Vogan, Public Works Director/City Engineer

Subject:         Capital Improvement Program Update


The Public Works and Engineering capital improvement staff, in collaboration with various
other City staff members; are currently working on numerous design and construction
projects. Many of these projects are carryovers from the prior fiscal year, while a few are the
result of the CIP update approved for this fiscal year. The following is a brief status report on
the active projects:
      •   Sierracrete Study- While not a standalone capital project, the Sierracrete study was
          to be the precursor to remediating the pavement issues that accompany this
          structurally flawed road base material. Although the County Health Department
          concluded several years ago that there was no health risk posed by the material, the
          poor performance of the pavement has clearly indicated that the material is inferior to
          traditional base rock. The study concluded that in general Sierracrete deteriorates
          roughly twice as fast as a traditional roadway. Structurally speaking, it would take
          more the twice the depth of asphalt over an equivalent depth of Sierracrete to provide
          the same support as a traditional roadway (i.e., 4.5" of asphalt over 6" of Sierracrete
          would be equivalent to 2" and asphalt over 6" of baserock).

          The study provides several remediation recommendations, the most expensive of
          which would be to entirely remove and replace all the Sierracrete material (roughly
          $13 per square foot). Since there are roughly 11 miles of Sierracrete streets in
          Oakley, full removal is probably not economically feasible unless outside sources
          can be identified. Since the bulk of the Sierracrete streets are in neighborhoods as
          opposed to collectors and arterials, staff believes that a more economically feasible
          approach will be to increase the surface treatment frequency for the Sierracrete

        neighborhoods and to completely remove Sierracrete from the collectors and
        arterials.

        The logic behind staff's recommendation is that since neighborhood streets have less
        heavy vehicle weight and volume, their treatments are typically less expensive.
        Projects typically include limited digouts, crack sealing, and slurry sealing. Based on
        the report recommendations the City's surface treatment designer has developed a
        detail for the Sierracrete streets that includes a focused pavement removal in the
        areas that have surface cracking, a full depth removal in the failed areas, and a
        typical slurry seal for the remainder of the roadway. While the cost will be more
        expensive then our normal neighborhood treatment program the result should be a
        better functioning pavement. Staff is proposing that this approach be used in our next
        neighborhood treatment project (as described in the CIP 14 update, the next
        neighborhood to receive treatment will be the area north of Main and west of Miguel).

        As opposed to the neighborhood treatments, arterial and collector pavement rehab
        projects are much more involved and expensive. The extent of Sierracrete on these
        streets is pretty limited. As opposed to the increased maintenance frequency
        approach, staff believes these roadways will be better served by completely
        removing the Sierracrete material. The reconstructed roadway will perform better
        over time and the higher initial investment will result in a more efficient long term
        maintenance program. As discussed in the CIP 14 update, the first roadway to
        receive this treatment will be Empire Avenue between Main Street and Oakley Road.

    •   Project 11, Main Street Downtown- This project will reconstruct and reconfigure
        existing Main Street in the downtown area from roughly Vintage Parkway to
        Norcross. The project will include a center landscaped median, one lane of traffic in
        each direction, and angled parking stalls on each side as well as enhanced .
        landscaping and street furniture. The design has been started and construction is
        anticipated to begin in the spring of 2012.

    •   Project 12, Citywide Safety and Traffic Management Improvements- This annual
        project implements spot transportation safety improvements such as the
        Neighborhood Traffic Management Program (NTMP). Areas being studied include
        Silverspur Lane cut-through and speeds, Barndance Way volumes and speeds, and
        the Charles Way neighborhood volumes and speeds. The project also recently
        installed over a dozen radar speed signs that have been very well received by the
        community.

    •   Project 13, Citywide Frontage Improvement Gap Closures- This annual project is
        used to fill in gaps in sidewalks throughout the City. The project on Empire Avenue at
        Oakley Road is well underway and is ahead of schedule. This project is also
        constructing medians in Empire Avenue and is incorporating a pavement
        rehabilitation project from roughly Holly Drive to Main Street. The pavement rehab

        project was designed prior to the Sierracrete study, and the study confirms that there
        is a confined amount of Sierracrete in some of the areas that the County widened.
        Staff is working with the contractor to define the limits for removal and a change order
        will be prepared to remove the Sierracrete completely. It is likely that the change
        order amount will exceed Staffs approval authority so it will probably be presented to
        the City Council in October. Upcoming phases of gap closures will likely include
        Empire at Bedford, the last remaining gaps on Cypress, and Main Street projects
        following the relinquishment (such as the small gap between the mobile home park
        and Oil Can Henry).

    •   Project 14, Citywide Pavement Management- This annual project is used to perform
        preventative maintenance on streets throughout the City. A neighborhood slurry seal
        project has been designed for the area north of Main and west of Miguel. The
        neighborhood includes Sierra crete so the project will be the start of that remediation
        effort. A separate project has been designed for Cypress Road between Empire and
        Rose. These repairs are more extensive then the slurry seal project, so the Cypress
        project will follow the bidding of the neighborhood project and may be phased
        depending on available budget.

    •   Project 23, Main Street Medians, Bridgehead to Live Oak- This new project will install
        landscaped medians on Main Street from Bridgehead Road to as far east as funds
        will allow, (likely between Sandy Lane and Live Oak Avenue). The design
        agreement, which includes plans, specifications, and construction estimates for the
        entire stretch of Main Street from Bridgehead to Big Break, was approved at the first
        September meeting.

    •    Project 77, Citywide Street Name Signs- This is the sixth installment of this project to
         replace all street name signs in Oakley with the current decorative standard.The
         project has replaced all arterial and collector street signs and will continue to
         transition into neighborhoods.

    •    Project 91, O'Hara/Cypress Signalization- This project to widen and signalize the
         O'Hara and Cypress intersection is mostly complete, with only punchlist items
         remaining.

    •    Project 92, Neroly Road Westerly Extension- This project to construct the westerly
         extension of Neroly Road from the new Neroly/Empire intersection is currently under
         construction. The project has been on hold while PG&E coordinates and schedules
         the utility connections, but the contractor should complete the project in October.

    •    Project 96, O'Hara Widening, Cypress to Laurel- This project will widen O'Hara
         Avenue as a four lane divided arterial from Laurel Road north across the CCWD
         canal and in front of the Moura parcel. The project will also complete frontage
         improvements on the west side of O'Hara just north of Chianti. Design,

        environmental, and property acquisition are underway. Staff is also coordinating
        access modifications and parking restrictions with the elementary school district. The
        project is planned to be constructed in the summer of 2012.

    •   Project 100, Live Oak Storm Water Outfall- This project, to construct the detention
        basin outfall and three inlet structures for the existing basin west of Live Oak Avenue
        as well as a sewer extension in Live Oak was recently bid for the second time. The
        engineer's estimate for the project was less then $750,000 and bids again were in
        excess of $1.2 million. Staff is analyzing the bids and available funds to determine if
        there is a common issue driving the cost, and if the project may be able to be
        phased.

    •   Project 105, Main Street Frontage Improvements- This project, to install frontage
        improvements and the poles for a future traffic signal on the south side of Main
        between the Public Storage center and the Raley's Shopping Center is 90%
        designed. The project will be constructed once Main Street has been relinquished,
        which should make the project cheaper and easier to implement.

    •   Project 113, O'Hara Widening, Carpenter to Vintage- Design is nearing coQ]lletion,
        and PG&E is finalizing the utility relocation plans. An arborist has been retained to
        make recommendations on preserving the redwood tree. Construction will follow the
        utility relocation.

    •   Project 116, Marsh Creek Restoration- Design of this project to widen Marsh Creek
        and restore habitat is nearly complete and resource agency permits have been
        applied for. Construction is planned for the spring of 2012.

    •   Project 123, Holly Creek Park Phase II- Construction of this project to place irrigation
        and turf in the basin portion of the park is mostly complete and the plant
        establishment period is underway. The park is expected to be open for use at the
        beginning of November.

    •   Project 124, Laurel Road Widening, O'Hara to Rose- This project, to widen the north
        side of Laurel from O'Hara to Rose Avenue, is currently under design. The project
        will realign the Laurel Ballfields driveway with Cloverbrook Avenue and will expand
        the parking lot at the park. The project is expected to go to construction next fall.

    •   Project 125, LED Streetlight Replacement- This project will replace several hundred
        high pressure sodium streetlights with LED technology. All project agreements with
        PG&E have been approved, and PG&E reports that the materials have been ordered
        and the contractor has been selected. The lighting supplier indicates that the lights
        are in high demand and are being delivered as quickly as they can be manufactured.

    •    Project 128, Live Oak and Oakley Road Pedestrian Pathway- This project which
         constructed a pedestrian pathway on the north side of Oakley Road and the east
         side of Live Oak Avenue to connect the Heather Park neighborhood to Orchard Park
         School is mostly complete. Only punchlist items remain. The project seems to have
         been well received by the community.

    •    Project 130, Crockett Park All Access Playground- This project will replace the
         obsolete play equipment at Crockett Park with modern all abilities play equipment.
         Proposals have been obtained from three suppliers and the equipment will be
         ordered as soon as one has been selected. Delivery team and installation should
         take a month to six weeks.

    •    Project 131, Oakley Downtown Revitalization -In conjunction with Project 11, two
         new restaurants will be constructed on Main Street in front of City Hall, along with a
         public plaza between the restaurants. The City Council has approved the design and
         the Disposition and Development Agreements required to proceed with the project,
         and the design work on the restaurants is well underway. Also, the current Oakley
         Plaza strip mall and the CentroMart buildings will receive new facades and the
         associated parking lot will be rehabilitated. The Ad-Hoc Committee has reviewed
         some preliminary designs and will present those ideas during a work session at the
         September 2ih City Council Meeting.
