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. .. 1997 SLURRY SEAL PROGRAM Area 1 Juarez Lane Peppertree Road (Silvergate to Shannon) Castillian Road (Silvergate to Padre) Padre Way Fenwick Way Fenwick Place Fenwick Court Royston Court.

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. Signature Mayor: Date: Signature Posted By: Signature Date:
