TERRY HUFFMAN, PHD

President /Senior Wetland Regulatory Scientist

Terry has a unique combination of in-depth experience with ecological research and the environmental regulatory process. Prior to starting Huffman-Broadway Group, Inc., he was the US Army Corps of Engineers’ (Corps) Chief Wetlands Scientist at the Corps’ Environmental Laboratory in Vicksburg Mississippi, where he developed the wetlands definition used by the Corps and the US Environmental Protection Agency (EPA). He pioneered the combined use of multiple environmental factors of wetland vegetation, soil and hydrology conditions and their identification through the use of field indicators to determine the presence or absence of wetlands subject to regulation under the Clean Water Act. This seminal work led to the development of the wetland delineation methodology in use by the Corps and EPA today. As noted in the preface to the Corps’ 1987 Wetlands Delineation Manual, Part II of the Manual is based on Terry’s 1980 paper entitled “Multiple Parameter Approach to the Field Identification and Delineation of Wetlands.” As a lead technical representative for the Corps, Terry also played a major role in developing the language pertaining to wetlands in the EPA 404(b)(1) Guidelines for the discharge of dredged or fill material into waters of the US, including wetlands. His nearly 35 years of work with the Corps and as a private consultant has provided Terry with extensive onsite experience with virtually all types of aquatic and wetland environments and a unique understanding of the environmental permitting and compliance process.
