I think by turning up for the meeting will be important to hear the proposals. I do believe they have the intent to qualify this in such a way that we will always be able to keep it as a beach dive, and add markers to help designate safe zone for divers, and boaters - you all stay over there, and fisherman you can fish over here. It makes for a happy family. I think it will be very worth while to attend.
Please note that the Blue Heron Bridge is a very special area blessed by creatures on journey and some that are residential. Being so close to the Gulf Stream current brings in a polithera of unusual creatures and marine migrations of many many varieties.
Designating an area as a Sanctuary is only part of the issue. The word "sanctuary" in the eyes of government often doesn't mean protection. There are marina sanctuaries where fishing is allowed - good example being the Keys National Marine Sanctuary - parts of it are off limits to fishing, and parts are even off limits to diving. Much of it, though is available to fishing and lobster trapping - even on a commercial basis. So, the question is, what protections are being sought with this effort? This is a can of worms that should opened carefully - for example, I would not want BHB diving to be required to be done with a commercial operator - and there are example of sanctuaries where this is required.
