At its meeting of July 26, 2011, the City Council approved plans and specifications for

program by slurry sealing aged asphalt concrete pavement on street segments in Area

to extend and preserve the pavement life on City streets.
On September 13, 2011, the City Council awarded Cash Contract No. S.S. 633 to
American Asphalt South, Incorporated for the Slurry Seal Project Area “B” & Remainder
of Area “A.”

completed per previously approved plans and specifications and to the satisfaction of
the Director of Public Works. Therefore, the project is deemed complete and staff
recommends releasing the remaining retention funds to American Asphalt South, Inc.
Under the Slurry Seal Project Area “B” & Remainder of Area “A, a total of seventy-one
residential street segments and three arterial street segments were sealed, covering a
total of approximately ten linear miles of roadway. Specifically, the improvements
