Environmental Impact Assessment and Permitting


Decision makers use environmental impact documents to determine the potential effect of proposed actions on the environment. Applied Coastal provides expert analysis of waves, currents, sediment transport, and geologic deposits influencing dredging and construction activities from the continental slope to the coastal plain. Detailed analyses of existing conditions and an evaluation of the potential impacts caused by proposed actions is the foundation for all National Environmental Policy Act (NEPA) documents that are required for all major engineering activities in the coastal zone. Applied Coastal personnel have identified issues pertaining to proposed actions, conducted literature reviews to assist in assessing problem scope, evaluated potential impacts of proposed actions, and provide environmental permitting support. We rely on remote sensing and GIS technologies as a means of analyzing historical change relative to the condition of ecosystems and resources, and numerical modeling technology for predicting potential impacts.
