PD&E studies are FDOT’s comprehensive approach to federal requirements under the National Environmental Policy Act (NEPA). We study the potential effects of a proposed project and evaluate how they might impact the social, physical, natural, and cultural/archeological environments. These studies are completed in tandem with the conceptual design process so that projects are developed in the most efficient way to reduce impacts to the human and natural environments. PGA’s PD&E Group offers a wide variety of services that contribute to PD&E studies, as well as managing them ourselves.
