In NJ you are allowed to have as many lights installed with out question BUT they all have to work.
Some thing tells me you are not a very good house keeper.
check out 5 quarter Southern Yellow Pine for decking strong as oak a lot cheaper and apply a water proofing liquid like Thompsons one a year.
Think about Southern Yellow Pine,find a saw mill or lumber yard,tell them what you think you will need,if it is T&G the saw mill can make it up...
