[ NCHRP 25-25 (Research for the AASHTO Standing Committee on the Environment) ]

  Project Data
Funds: $49,858
Research Agency: Parsons Brinckerhoff Quade & Douglas
Principal Investigator: Joe Crossett, TransTech Management
Effective Date: 9/30/2003
Completion Date: 9/30/2004

When developing EA and EIS project documentation, many authors have taken the "more is better" approach to ensure all areas have been documented to the fullest extent possible. This has resulted in rather lengthy and detailed NEPA documentation when it may be possible to ensure environmental protection and accomplish the same decision-making process with briefer, more focused NEPA discussion. The objective of this study is to research the nationwide experiences regarding NEPA data needs to develop a better understanding of the optimum and appropriate level of documentation needed to make a decision.
