Another Hole

Recently I posted a picture of a deep pothole near my house.  Or maybe it would be more accurate to call it a sinkhole.  It opened up in a hole several feet deep.  Today I ran across another one.  The local populace is really good about trying to mark such disasters-in-waiting but the question is why they keep appearing on roads that have relatively recently been paved?  This is the third hole within a mile of my house.  Does anyone in officialdom notice these?  Do they actual do anything about them, as in requiring the contractor to come and repair it?  Or telling the street department to do it?  There’s no sign of such initiative.
