This year's Annual Overlay Program consisted of reconstructing Village Parkway -- between Kimball Avenue and Amador Valley Blvd., both northbound and southbound lanes. In a normal overlay, failed areas are dug out and repaired and then pavement reinforcing fabric and 1 1/2 inches of asphalt paving are placed over the entire surface. Apparently, Alameda County performed at least two overlays on Village Parkway, which has resulted in a higher-than-usual crown. The street also needed extensive repair due to numerous failed asphalt areas which have reflected up through the previous overlays. Because of these existing conditions, the normal overlay process could not effectively be used. Raising the crown another 1 1/2 inches as in a normal overlay would have caused further drainage problems, and unrepaired deep asphalt failures would continue to deteriorate the surface. Therefore, Staff prepared the contract to include the reconstruction of the road pavement by removing 4 inches of asphalt concrete from the outside lanes and a minimum of 6 inches from the center (crown) of the roadway. The entire surface was then repaved with reinforcing fabric and 4 inches of asphalt, thereby lowering the crown a minimum of 2 inches. I CITY CLERK The project was approved for grant funds from the State-Local Transportation Partnership Program (SB300 gas tax). During the course of the project, extensive base failures occurred due to subsurface water, and a large Change Order was approved by the City Council to properly complete the roadway repairs. It was decided to borrow monies from the 1994-95 Overlay Program to pay for these unexpected repairs and thus downsize next year's Overlay Program. The City Engineer has reviewed the work on the project and determined that it is complete and in accordance with the approved plans and specifications. Staff recommends that the City Council accept the improvements and authorize payment and retention to Meridian Paving & Grading in the amount of $26,654.23. a:~overlay~agstacpt - 2 -
