FROM: Jay D. Walter, Director of Public Works how
Prepared By: Barbara Lynch, City Engineer
SUBJECT: LOS OSOS VALLEY ROAD ROAD PAVEMENT REPAIR,
SPECIFICATION NO. 91004.
RECOMMENDATIONS
1. Authorize staff to advertise for bids for the repair of the pavement on the Los Osos Valley
Road and authorize the City Manager to award the contract if the lowest responsible bid is
less than or equal to the Engineer's Estimate of$120,000. .
2. Approve the transfer of $151,500 from the Street Reconstruction master project account to
the project accounts to fund design support and construction.
3. Approve a sole source purchase order with Dokken Engineering in an amount not to exceed
$15,000 to prepare project plans and obtain State of California Department of Transportation
encroachment permit for this work.
DISCUSSION
Recent rains have aggravated road conditions in some areas of the City. The most noticed of
these is the stretch of Los Osos Valley Road between the Highway 101 northbound and
southbound on and off-ramps. While the bridge structure and maintenance is the responsibility of
Caltrans, the pavement on top of the bridge and on the approaches is the responsibility of the
City, per the maintenance agreement in place with Caltrans. Maintenance by local agencies of the
pavement surface on Caltrans structures is a normal practice.
The worst areas on Los Osos Valley Road are in the immediate vicinity of both the north and
southbound ramps. This, coupled with the narrowness of the bridge crossing has made repairs
difficult. The condition of the pavement is such that holes are continuing to grow as the
pavement overlay delaminates from the bridge deck. Staff has attempted on a couple of occasions
to place temporary patch material in the large holes that have developed, but the material has not
stayed in place. Drivers have been uncooperative during flagging operations, resulting in danger
to themselves, other drivers, and staff.
Investigative work is planned by the consultants for the Los Osos Valley Road interchange
project and they have an encroachment permit from Caltrans for a southbound ramp closure to
occur at night. Staff originally thought the City might be able to complete some work at night
during the closure for the investigative work, but neither the duration nor the extent of the
closure are long enough to achieve the needed work. Staff is now pursuing a short turn-around

project to be completed by a contractor. Because of the high degree of disruption to the area to
complete repairs, staff is planning a full restoration project for this short stretch so that additional
closures will not be needed during summer paving operations. This work was planned to occur_
this summer, but staff feels that because of the deteriorating condition, combined with the high
traffic volumes, this work should occur as soon as possible.
CONCURRENCE
Community Development has issued a Notice of Exemption for this project. Staff is anticipating
a request from Caltrans to do the work at night. If such a request is made, engineering staff will
work with the Community Development Department on obtaining permission for night work, or
negotiating with Caltrans for other hours.
FISCAL IMPACT
This project will be funded from the master Capital Improvement Project account for Street
Reconstruction and Resurfacing(R&R), the same account that would be used when the work was
to occur this summer.
Dokken Engineering is currently under contract with the City to complete the design of the
interchange project in the same location. They have already developed plan layouts of the area
and have an encroachment permit with Caltrans for investigative work. Staff is proposing that a
small portion of the funding be used to have Dokken Engineering provide a simple construction
plan and obtain permission under their existing encroachment permit with Caltrans for the
necessary ramp closures and traffic control. Staff believes this will substantially expedite the
process.
The 2009-11 Financial Plan, Appendix B, pages 3-143 through 3-145, identifies $1,825,000 in
the 2009-10 fiscal year for Street R&R construction projects. This amount, in addition to
previous year carry-over funding, brings the current total available in the master account to
$2,483,492. There is sufficient funding in the master account to support this project request.

ALTERNATIVE
Delay the project Rehabilitation of this section of roadway could be delayed and the work
completed with other paving work planned to occur this summer. This could reduce the cost by
bidding the work as a part of a larger project. This would result in continued pavement
deterioration and complaints until repairs were made. Maintenance staff has attempted repairs in
the past and cannot rely on the patch material to stay in place. .
