Environmental Impact Statement (EIS): An environmental impact statement (EIS) is a disclosure document that provides a complete analysis of all appropriate impact areas and provides a means for agencies, project sponsors, and the public to consider an action's significant adverse environmental impacts, alternatives, and mitigations. An EIS facilitates the weighing of social, economic, and environmental factors early in the planning and decision-making process. A draft EIS (DEIS) is the initial statement that is circulated for public review and comment, which are then incorporated (as appropriate) into the DEIS to produce a final EIS (FEIS). The FEIS is the disclosure document upon which the lead and involved agencies base their decisions as set forth in a Statement of Findings. (NYC Mayor's Office of Sustainability)
