Meeting Date: 3/6/2018
FROM: Daryl R. Grigsby, Director of Public Works
Prepared By: Brian Nelson, Acting Supervising Civil Engineer
SUBJECT: CONCRETE STREETS AND ACCESSIBILITY IMPROVEMENTS PROJECT,
SPECIFICATION NO. 91455
RECOMMENDATION
1. Approve plans and specifications for the Concrete Streets and Accessibility Improvements
Project, Specification Number. 91455; and
2. Authorize staff to advertise for bids and authorize the City Manager to award the
construction contract if the lowest responsible bid is within the Engineer’s Estimate of
$660,000.
DISCUSSION
Background
The City’s Pavement Maintenance Plan (Pavement Plan) was adopted by the City Council on
April 14, 1998. A key element of the Pavement Plan is the establishment of a rotating and
methodical approach to ensuring all areas of the City receive regular preventative or corrective
maintenance. The City has applied this approach to asphalt streets, which represent over 99% of
City streets. This routine maintenance approach was not suitable to the City’s concrete streets,
however, due to the relative longevity of concrete pavement and high costs of concrete
maintenance. As a result, the City has several concrete streets which have never received
maintenance. Furthermore, the City’s most recent Pavement Condition Survey indicated that,
while overall Pavement Condition Index (PCI) has increase from 72 to 73; the concrete streets
have declined to 35.
Three concrete intersections included in this project have been identified as in need of attention.
The intersections include Dana and Nipomo, Palm and Toro, and Palm and Johnson. These
intersections are very uneven and present a challenge to pedestrians crossing the street,
particularly those with mobility limitations. This project will allow for complete reconstruction
of these intersections, including upgraded new curb ramp facilities, without impacting funding
for regularly planned neighborhood paving. The new intersections will be safer and more
accessible. Additionally, Dana Street, which is in poor condition, will receive an asphalt concrete
overlay which will remove surface irregularities, seal cracks, and bring the roadway back to
excellent condition.
Completion of the Concrete Streets and Accessibility Improvements Project will enable the City
to make progress towards the Council’s established goal of maintaining at least 70% of streets in
good condition and have no less than 7% of the City’s streets in bad condition. This project also
helps implement multimodal improvements, a Major City Goal, due to the installation of curb
ramps and providing a smoother roadway surface which is more conducive to bicycle

transportation needs.
ENVIRONMENTAL REVIEW
This project is categorically exempt from environmental review pursuant to section 15301 of the
CEQA Guidelines (Existing Facilities) since it is a maintenance and replacement project. A
Notice of Exemption has been filed through the Community Development Department.
FISCAL IMPACT
There is currently a balance of $920,000 in the Street Reconstruction and Resurfacing Master
Account (Specification Number 90346). A portion of those funds will be used for construction
of the upcoming CDBG Marsh Street Ramps Project, leaving a balance of $840,000 for
construction of this project, which is sufficient to support this request.
Other sources of funding include the Water Distribution System Improvements Master Account
($3,783,838) and the Collections System Improvement Master Account ($2,512,683). These
funding sources support adjustment of water and sewer facilities to the new pavement elevations.
This project is 95% funded through the Local Revenue Measure.

Concrete Streets and Accessibility Improvements Project (91455)
Remaining Street Reconstruction and Resurfacing Master Account funding is planned to be used
for the Roadway Sealing project planned for summer 2018.
ALTERNATIVES
1. Deny authorization to advertise. The City Council may choose not to authorize project
advertisement. This is not recommended since summer is the best time to pave streets and
impacts to the public and adjacent schools will be minimized.
