BACKGROUND: The Engineering Division inspects and rates 1/3 of the City's streets on a yearly basis. The results of this inspection are input into a computer database which is used to project the future condition of the streets based on their current condition, surface type (i.e. brick, concrete, asphalt, etc.), average daily traffic, traffic type (i.e. trucks, cars, etc.). This data, paired with available funding, is used to prepare the yearly street improvement program. Staff then determines which streets need to have the surface restored or be totally reconstructed. The Street Restoration project generally involves the placement of a 1 to 2 inch hot mix asphalt surface course on an existing paved surface that has been prepared to receive the overlay. A ' portion of the existing pavement surface is often removed by cold milling to reduce the impact of the overlay to existing curbs, driveways, etc., unless additional structural capacity is desired in the pavement. The purpose of the street restoration program is to increase the useful life of a pavement in advance of its deteriorating to a condition that would require its complete reconstruction and improve the street's ride ability. This year's program will include approximately 12 centerline miles of streets in the City. A final listing of the streets in this year's program is attached. The project specifications were prepared by the Engineering Divioject was advertised on March 26, 2004 and bids were received on April 13, 2004. The results of the letting are as follows (bid tabulation attached):
