At any point in time, there are projects
requiring fill and projects with excess fill
needing to be exported.  A website attempts to link up
those with supply and those with demand.  As
the situation is, by definition, dynamic, the price
fluctuates widely.

There are usually move sites seeking export
than import, in which case, the dumpsite of
choice for Southern Orange County tends to be
Camp Pendleton, where dump fees are about
$80 per truck (10-wheeler).
