 Technical Committee on Environmental Design

 Work Underway/Planned for 2009
  • Coordinating with the NCHRP project panel
      updating the 1991 Guide for Transportation
      Landscape and Environmental Design.
  •   Proposed activities:
       Web-based guidance on new methods for
        retaining and using storm water runoff in
        ROW (jointly with TCHH)
       AASHTO’s CSS work and publications
        TRB Task Forces on CSS and
        Visualization
                                              27
Technical Committee on Environmental Design

 Publications (current or proposed) that the
  TCED committee is interested in
  participating in updating/developing, now
  or in the future, include:
  •   On-Site Drainage Retention, not Conveyance
      (currently proposed as a new topic)
  •   Developing and Retaining an Effective CSS
      Program (currently proposed as a new topic)




                                                    28
Technical Committee on Environmental Design

 5-Year Goals
 1. Retain multi-disciplinary membership
 2. Gain exception from SCOH/SCOD rule which limits eligible
      Chairs of Technical Committees
 3.   Fill remaining vacancies
 4.   Gain approval for 1 additional Region 4 member
 5.   Share CSS activities
 6.   Publication updates
      1. 2nd request to place pocket-sized 40-page 1993 Guide
            on Evaluation and Abatement of Traffic Noise on the
            AASHTO Web site. We have determined the guidance to
            still be current, but few ask for it in printed version.

                                                                29
