DISCUSSION
The Public Works Services Department is responsible for the maintenance and repair of
approximately 147 miles of pavement within the community. In 1999, as part of the
Pavement Management Program, staff prioritized the condition of all City streets and
established an eight (8) year slurry seal program to efficiently prolong the life of City
streets. The 2007/2008 Capital Improvement Program includes the Annual Asphalt and
Concrete Program for this work. The Department is scheduled to slurry seal approximately
18.5 miles of City residential streets per year. The attachment is a map of the area where
the work was performed for FY 2008-2009.

An asphalt slurry seal is a mixture of well-graded fine aggregate, emulsified asphalt and
water applied to the street pavement as a surface treatment. It is designed for both
preventive and corrective maintenance to older pavement surfaces where surface cracks
and loss of surface material are evident. This process makes the pavement impermeable
to air, water and improves skid resistance. To reduce the need for more costly
maintenance or construction work in the future, this application is repeated once every
eight years.
The Slurry Seal Project is awarded on an amount based on the engineer's estimate of
quantities and the low bidder's unit bid prices. The final contract amount is based on
actual installed quantities based on specific field conditions; such as, pavement surface
texture, undulations, and indentations; therefore, the awarded contract amount and final
contract amounts vary. The difference between the contract amount as bid and the actual
material cost is identified in Table 1 below as Contract Savings.
In addition to the work originally covered by the contract, and contract savings, two (2)
Contract Change Orders (CCO) were written.
CCO#1, for the amount of 36,594.10, was issued to the contractor for additional streets
affected by the Sanitation Districts of Los Angeles County Sewer Relief Project. The work
of this change was pre approved by City Council on May 5, 2009. CCO#2, for the amount
of $20,050 was issued for the slurry of Orange Grove Avenue within the City of Sierra
Madre. The cost of the work performed in Sierra Madre was added at the request of the
City of Sierra Madre . The cost for this work will be reimbursed to the City of Arcadia by the
City of Sierra Madre at the close of the project.
