Environmental impact assessment is now firmly established as an important and often mandatory part of proposing any development project. Environmental Impact Assessment in the United States provides foundational knowledge of environmental review in the United States as carried out at federal, state, and local levels, with detailed information about the National Environmental Policy Act (NEPA) and its applications, and other relevant federal and state legislation. This book will aid planners, architects, engineers, project managers, or consultants who work with environmental impact statements to assess the effects of a proposed activity on the environment and who develop and assess measures to avoid or minimize those impacts. It will serve as a desk reference for professional environmental planners as well as a core textbook for students who intend to work in the fields of environmental policy, civil engineering, environmental law, resources management, or other areas of environmental management.
