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
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
• 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
• 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
• 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
• 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
• 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.
