He specializes in projects that are often large, complex, or controversial, and involve a combination of land use, environmental permitting, and other constraints. Dr. Latimer’s projects typically involve issues related to site evaluation and constraints analysis, wetlands, water quality, the Endangered Species Act (ESA), and the National Environmental Policy Act (NEPA). Dr. Latimer has extensive experience related specifically to planning, permitting, and implementing projects that challenge the built?natural environment interface, including landfills, mines, sewage treatment facilities, and similar developments. He has a solid understanding of engineering concepts and practices and is adept at working collaboratively with engineering professionals to ensure optimum balance between environmental and engineering constraints. These projects often require careful assessments of alternatives, impacts, and opportunities (including value engineering), as well as ensuring that the project and the associated public process (e.g., NEPA, local land use, etc.) is technically well supported. Dr. Latimer is also an adjunct professor at Portland State University where he develops and teaches environmental permitting and compliance workshops for professionals, including environmental project management, NEPA, wetlands, water quality, and endangered species.
