Other things to consider:
- What is on the other side of the beach? Is it a causeway (like Dunedin), parking lot? private residnces/condos? If it's private residences, you'll need to go to those owners and get their blessings. I know how that sounds, but if you try to do something like this in front of their homes and they bitch to City Hall, you'll find yourself out in the cold really quick.

-Are there turtle populations in the area? If so, the turtle people will probably object. Same with the bird people.

I know that I sound like a nay-sayer, but again, this is what I do for a living, and I have seen some really great ideas get shot down for some really silly reasons brought up by 1 or 2 people!
