SUBJECT: STREET RECONSTRUCTION AND RESURFACING PROJECT,
SPECIFICATION NO. 90346
CAO RECOMMENDATION
Approve additional funding for the Street Reconstruction and Resurfacing Project.
DISCUSSION
Work is nearly complete for the summer street reconstruction project. During the third week of
August, virtually all of the asphalt was placed. The construction crew encountered a couple of
problems in the paving areas which resulted in the use of additional asphalt beyond that
accounted for in the project proposal. In the Oceanaire Area it was discovered that the streets
were built on a sandy, pebbly material rather than an accepted base material. The material did
not stay compacted once the existing layer of asphalt was removed, but moved around when a
vehicle drove on it. The loosest areas were removed and replaced with asphalt prior to paving.
In a couple of areas, the asphalt was thickened during the paving area to bridge weak spots and
allow the pavement to be placed and compacted properly. A couple of areas in the Oceanaire
area and the Pepper Street alley were wet to the point that they pushed through the new
pavement as it was being constructed. The work was stopped and the area removed and a deep
section of asphalt replaced to allow paving to continue. Final totals of the asphalt laid during the
week show we have exceeded our original asphalt estimate by about 25%.
FISCAL IMPACT
Funding for the General Fund portion will come from the existing street paving project account.
Adequate funds remain from the 2002-03 street reconstruction budget to cover the additional
costs.
