627.706, Florida Statutes, 'sinkhole' means a landform created by subsidence of soil, sediment, or rock as underlying strata are dissolved by groundwater." Sinkholes are common and a natural occurrence in Florida due to the process of water dissolving the porous limestone. This process will slowly create underground cavities that can cause the top ground to collapse or sink.
What this says in a nut shell is that sinkhole are from THE BOTTOM UP. What we have in this situation is to much rain washing away a little sand outside the path and may have caused the path to weaken and crack out into the path about 18 inches from the curb. they will cut out the cracked blacktop, put in some crushed gravel and patch the hole with blacktop. When and if you have a true sink hole, the maintenance folks will rope off not only the area, but a good distance in all directions from the sink hole.
