Pot Hole Repair
The Operations and Maintenance Division repairs many potholes each year through
a private contractor. A pothole is an area of the roadway that is missing a piece
or pieces of pavement and a hole has been created. As the diagrams show, water is
the main culprit and the pavement continues to deteriorate and the pothole worsens
as vehicles run over them or hit them.
A pothole is fixed by removing the loose pavement and cleaning the hole, then spraying
it with a tack coat of liquid asphalt. Next, hot asphalt is compacted into the hole
and the surfaced leveled and rolled to create a smooth surface. In some cases, the
deteriorated area will require a larger area to be removed by saw-cutting additional
pavement around the pothole, removing additional amounts of pavement, aggregate
base and the underlying soil, and then filling the area with new hot asphalt to
be compacted and smoothed.
If you notice a crack or pothole on a county street, you may submit a
 service request or contact
the Operations & Maintenance office at  (714) 955-0200. An Inspector will be
sent to inspect the area and then schedule a crew to make the necessary repairs
as needed.
