Services Director Assistant City Manag~r Page 1 of 2 ITEM NO. `7'' ~ ~ ~ DESCRIPTION: On May 4, 2010, the City Council awarded Contract No. 10-04, 2009-2010 Annual Street Overlay Program to G. Bortolotto & Co., Inc. The Annual Street Overlay project consists of removing and replacing failed asphalt concrete (AC) pavement and resurfacing the street with a minimum 1-1/2-inch overlay of AC, and re-striping pavement markings. Wineberry Way is one of the streets included in the Annual Overlay Program. It has been identified that approximately 60 LF of 12-inch reinforced concrete storm drain pipe on Wineberry Way requires repair (Attachment 1). Staff recommends completing this repair prior to resurFacing the street. The total cost to repair the storm drain is $9,174, including a 10% contingency. The work can be completed under this contract and it is proposed to be funded from Gas Tax Reserves. A second modification to the contract is being recommended to address allowing traffic flow along Central Parkway later this summer. This work will involve additional pavement on Central Parkway befinreen Lockhart Street and Fallon Road (Attachment 2). The total cost of the additional pavement work is $53,471, including a 10% contingency. Central Parkway was constructed by the Lin Family as part of the Dublin Ranch backbone infrastructure. The existing Central Parkway improvements include the two center travel lanes and the median island as well as the outside travel lane and frontage improvements (curb and gutter) on the north side of Central Parkway adjacent to the Fallon Sports Park. The final completion of the outside travel lane and frontage improvements on the south side of the street were partially deferred, which is a common practice when the roadway will not be immediately open to general traffic. The work that was deferred was the placement of the top layer of asphalt concrete and curb and gutter. The original plan anticipated that the work would be constructed at a later date by the developer of the adjoining property in conjunction with the frontage improvements. As development has slowed there is currently no development with final approvals for construction on the property on the south side of the street. The City proposes to open Central Parkway to traffic this summer and Staff recommends that the top layer of pavement be installed at this time in order to provide the full pavement structural section in advance of traffic being placed on the street. The cost of constructing the inside travel lanes is part of the Eastern Dublin Traffic Impact Fee program and the additional pavement work should be paid by the fee. Adequate funds currently exist in the Eastern Dublin Traffic Impact Fee Section 1 reserves to complete this work. A Budget Change Form (Attachment 3) and Contract Change Order (Attachment 4) are presented for City Council approval. NOTICING REQUIREMENTS/PUBLIC OUTREACH: Public Noticing is not required.
