Long Island Sound Blue Plan Map Layers

The purpose of the Long Island Sound Blue Plan is to identify and protect places of traditional use and ecological significance, and to minimize conflicts, now and in the future. This includes preserving a collective vision of Long Island Sound, and facilitating a transparent, science-based decision-making process. The Long Island Sound Blue Plan process included (1) gathering data to develop an inventory of ecological resources and human uses and producing corresponding maps that were reviewed by experts and stakeholders for relevance and accuracy and (2) development of Blue Plan policy to be implemented though existing State permit processes that will minimize conflict with natural resources and traditional uses.
