Hurricane Matthew (October 8, 2016) dropped 16″ of rain in Goldsboro, NC, where I spend many weekends with my partner. The Neuse River flooded. (I only received 7″ of rain in Moncure, 85 miles to the west.)
These are a few pictures taken several weeks later, after the river has (mostly) returned to its normal limits and most people have dragged sodden drywall and carpets to the curb.
I am now looking for a consumer-grade device that can tell relative elevations within several inches, so we can figure out which parts of the property, if any, are dryer than others. (We left during the storm and didn’t see the actual water flow.)
We lost the furnaces and ductwork. The HVAC system has been replaced, and the new furnace sits on a higher base.
