1) Local County inspector said that concrete seawall being used as fill
was
an environmental hazard. I asked him if he knew what concrete was? He
didn't, I informed him that it's oyster shells (limestone) that have been
ground and kiln dried. Then pushing the issue I asked him if oyster shell
are a hazard ( we live in Florida). He then said that concrete has
additives that are a hazard. I informed him that the additives were also
products mined from the earth like Silica (sand) and Gypsum neither of
which
are hazards.


The environmental hazard as seen by beach huggers is not the content of
the material. It is the effects on the beach itself caused by armoring which
isn't natural.
