DESCRIPTION: On March 14, 1994, the City Council awarded Contract 94-01,
the Village Parkway Reconstruction/Overlay project, to Meridian Paving & Grading.
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.
