Meeting Date: 5/17/2016
FROM: Daryl Grigsby, Public Works Director
Prepared By: David Athey, Supervising Civil Engineer
SUBJECT: ROADWAY SEALING 2016, SPECIFICATION NO. 91311
RECOMMENDATION
1. Approve plans and specifications for the Roadway Sealing 2016 Project, Specification No.
91311; and
2. Authorize staff to advertise for bids and authorize the City Manager to award the contract if the
lowest responsible bid is within the Engineer’s Estimate of $1,199,705.
DISCUSSION
Background
The City’s Pavement Maintenance Plan (Pavement Plan) was adopted by the City Council on April
14, 1998. The Pavement Plan was updated to provide additional emphasis on arterial street
maintenance in 2009. A key Pavement Plan element is the establishment of a rotating and
methodical pavement maintenance approach. This ensures that entire City road system receives
regular preventative or corrective maintenance on a regular basis. Last summer, available street
maintenance funding from the City’s Local Revenue Measure was used for arterial maintenance
efforts on Johnson Avenue and Osos Street. Funding was not used for annual neighborhood street
sealing last year in accordance with Council’s direction. This year, the program funding will be
used to seal neighborhood pavement maintenance Areas 1 and 8 (Attachment A).
The intent of this project is to prevent more expensive maintenance work in the future. Preventative
and ongoing maintenance is less costly and more environmentally beneficial than street re-paving.
Ongoing neighborhood street maintenance also enables the City to make progress on the Council’s
established goal to maintain at least 70% of local streets in good condition and less than 7% in bad
condition.
In anticipation of this year’s roadway sealing project, the City’s Street Maintenance crew has
performed pavement repairs and crack sealing in pavement maintenance Areas 1 and 8. This
preparatory work increases the slurry seal application’s long-term effectiveness and reduces overall
construction costs.
Slurry seal is a mixture of asphalt emulsion, aggregates and water. The quality of the seal is very
much dependent on the quality of its materials. In the past, the City has used potable water from
fire hydrants. Recently, however, the City started using reclaimed water since it does not have
an effect on the slurry emulsion, it is more environmentally beneficial, and most importantly,

saves drinking water for potable uses. The City has saved tens of thousands of gallons since
switching to recycled water.
CONCURRENCES
This project is categorically exempt from environmental review pursuant to CEQA Guidelines
section 15301 (Existing Facilities) since it is a maintenance and replacement project and a Notice
of Exemption has been filed through the Community Development Department.
FISCAL IMPACT
There is currently $499,665 in the Street Reconstruction & Resurfacing Master Account;
however, several significant repairs are planned for completion on the arterial system through the
existing Job Order Contract. In addition, minor funding augmentation is required to support
required ramp construction work associated with Area 1 and 8. At this time it anticipated that
$300,000 will be available to support this and the 2016 CDBG 2016 Curb Ramps Project. In
addition, staff is recommending using $30,000 of Bicycle Facility Improvement funds to pay for
implementation of bicycle related striping. With the approval of the 2016-2017 Budget
Supplement, an additional $1,510,700 in construction funds will be available on July 1, 2016,
bringing the total funding available to $1,792,700 to support this request of $1,454,661. This
project will not be awarded until after July 1, 2016. A recommendation to award this project will
not be made until Council approves the 2016-17 Financial Plan Supplement.
These projects are 100% funded through the Local Revenue Measure, the half-cent revenue
enhancement measure approved by the City’s residents.

ALTERNATIVES
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 seal streets. School is
out and neighborhood traffic volume is lower.
