DESCRIPTION: On May 20, 1997, the City Council awarded the annual slurrs, seal ,
contract to Valley Slurry Seal. This project is a preventive maintenance application used to prolong the
life ora street. The material consists ora sand/oil mixture which seals cracks and provides a new uniform
wearing surface. The City streets are presently on a five- to seven-year cycle. Before seal coats are
applied to the streets, oil spots are removed and asphalt failures are repaired.
Asphalt repairs performed at the Dublin Sports Grounds parking lot exceeded the budgeted amount as the
repair was more extensive than originally estimated. During repair operations, the Contractor encountered
failures extending beyond the original marked areas and it was necessary to repair the pavement failures
to ensure a lasting Slurry Seal.
This year's project also experienced a cost overrun in the street repair. Cause of this overrun was due
to the last-minute addition of Elk Court for street repair. The addition was a response to the residents'
concern over the deteriorating condition of the street. Repairs at Serra Court also contributed to the higher
costs because extensive damage to the subgrade caused by the subterranean springs made it necessary to
repair more area than originally estimated.
Slurry sealing and striping of the Dublin Sports Grounds and Civic Center parking lots were included in
the Slurry Seal Street Program because of the similarity of work.
Attached as Exl~bit 2 is a Budget Change Form, which will appropriate funds in accordance with the
final project costs. The overrun on the Street portion of the project will be funded by an additional
appropriation fi-om Gas Tax Reserves. The Par'king Lot overrun will be accounted for with a transfer
fi.om the Budgeted Contingent Reserve.
The City Engineer has reviewed the work on the project and determined that it is complete and in
accordmnce with the approved specifications. Staffrecommends that the City Council accept the
improvements under this contract and approve the budget change to cover all improvement costs.

City Manager: Date:
;REASON FOR BUDGET CHANGE ENTRY: A single contract was used to perform the Annual Street Slurry
Seal Program on City Streets and the sealing ofparklng lois at the Civic Center and Sports Grounds. Pavement
Failure Repair for both surface streets and Dublin Sports Ground were more extensive than initially anticipated.
In order to immediately address deteriorating conditions, Elk Court was added to the project. Additionally,
S~ra Court required more repair because of damage to the subgrade caused by underground spring water. This
Budget Change will appropriate an additional amount of-Gas Tax Funds from Reserves.
When failure repair began on the Sports Grounds Parking Lot, areas beyond those originally outlined were
found to be in need of repair. The cost overrun is proposed to be covered by a mmsfer from the General Fund
Budgeted Contingent Reserve.
