So what's that dock made out of anyway?

As the dock moves toward completion I've been asked a few times about the materials used.  The piles are greenheart and the decking is purple heart.  They are both imported from South America.  This can raise concerns about whether the dock is being built out of eco friendly and sustainable materials or contributing to deforestation and global warming.

When the design work was started almost 4 years ago CBI and others raised the question/concern about what materials would be used and  advocated for the dock to be built out of sustainable resources.   For all of our information I have copied the relevent parts of the contract specs used by the DCR (Department of Conservation and Recreation) .
