Does this area form part of the RAMSAR wetlands conservation area? If it does as I think it does then use this as a defense because its one thing BCC is cautious of and knows full well the consequences of ignoring this. This then becomes a federal issue rather than local but good luck with it as dog owners are very intolerant of anything that takes away their dogs rights. I have seen police officers verbally abused by dog owners when requesting that the dogs be on a leash.
