on Implementation of Changes to the Section 4(f) Process
Friday, June 27, 2008 – 2:00 p.m.
406 Dirksen Senate Office Bldg.
Evaluating the Implementation of Section 4(f) Streamlining Provisions,
A Review of the U.S. Department of Transportation's Phase I Draft Study Plans:
June 9, 2008
This letter report will be the first of three to be issued in response to a congressional request in P.L. 109-59, The Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users. That Act required the U.S. Department of Transportation (DOT) to streamline the Section 4(f) evaluation process and to study the consequences of these regulatory changes. The Act also asked a Transportation Research Board committee to evaluate the design and outcomes of the U.S. DOT studies. In its first letter report, the committee finds that given the lack of baseline data and the qualitative nature of the issues under study, a truly experimental study design is not possible. Nonetheless, the committee makes several suggestions for how the proposed study design can be strengthened to allow reasonable inferences to be drawn.
This briefing was for members of Congress and congressional staff only. The report was publicly released on July 1, 2008 and can be found, in its entirety, on the Transportation Research Board’s Web site.
