Since when should government be deciding how people use their property? That isn't balancing interests, it is controlling property value.
Maybe I know something about Sustainable Development that you don't. I was on the very first Agenda21 roundtable in the US in 1994. I promise you, the process is totally corrupt, unconstitutional, and, at least so far as many "open government" and "public disclosure" laws are concerned, illegal. Sustainable Development in Florida, Smart Growth in Portland, or anywhere else for that matter follows the same blueprint. If you want to learn more about how poorly the results of the system were in Portland, go HERE. I suggest you buy and read Mr. O'Toole's book. But then, perhaps you should also read mine.
I invented a free-market means to "balance" any competing claim on property that are actually just to rural property owners. It allows them to market the natural attributes of their property. It is FAR more sophisticated than anything the environmentalists propose. If you check the Reviews of the book you will note development interests, wildlife biologists, foresters, timbermen, and regulators are speaking nothing but praise for it. Maybe you should be a little more circumspect.
