Review, develop, and recommend AASHTO positions on environmental design issues for the AASHTO Highway Subcommittee on Design, as required or assigned.
TCED Objective and Scope:
Primary responsibility to investigate current issues related to
environmental design and highways and
recommend positions to the SCOD.

4. 4 Technical Committee on Environmental Design Continuing coordination with the following committees:
Hydrology and Hydraulics.
AASHTO’s Context Sensitive Solutions/Design Task Force (or subsequent committee).
TRB Task Forces on CSS and Visualization in Transportation and the Committee on Landscape and Environmental Design. Multidisciplinary approach within the TCED and coordination with allied TCs:
Hydrology and Hydraulics, regarding storm water runoff concepts. Retention and use of water, rather than conveyance.
AASHTO’s Context Sensitive Solutions/Design Task Force (or subsequent committee), regarding stakeholder involvement.

Abatement of Traffic Noise (1993)
2004 review determined this to be current and relevant.
Recommend placing this document on the AASHTO web site.
The TCED provided a comprehensive review of this publication in 2004 and determined it to be current and relevant.
TCED is recommending that the 40-page half-size printed document be placed on the AASHTO web site.
Current TCED membership does not have expertise in Noise Abatement. Future reviews will rely on input from noise experts in our member DOTs.

7. 7 Guide to Wetland Mitigation Issues for Transportation Designers (1996)
2004 review determined this to be current.
Significant recent changes in wetland mitigation requirements warrants an evaluation of this document to be considered for a complete TCED review.
Guide to Wetland Mitigation Issues for Transportation Designers, 1996
Our 2004 review determined this to still be current, but enhanced usefulness would come from an on-line “Wetland Mitigation Best Practices” web page that all DOTs could reference, contribute to, and maintain. However, since 2004, significant changes in wetland mitigation such as the USACE’s shift to use banking found in the Compensatory Mitigation Rule for Losses of Aquatic Resources. Also, the Arid West supplement to the 1997 Wetland Delineation Manual issued in 2006 brings new requirements into determining where the delineation line should be which directly affects the amount of wetlands needed to mitigate. This will be considered for another possible review.

TCED review in 2004 determined this document to be obsolete.
TCED recommends it be REMOVED from the AASHTO web listing of TCED publications.
Policy on Land Use and Source Control Aspects of Traffic Noise Attenuation, 1980
The TCED 2004 review determined this 4-page booklet to be out of date and not worthy of rewrite, and we again recommend it be REMOVED from the AASHTO listing of TCED publications. It looks as though it has been removed from the Bookstore listing of publications; please remove from TCED web site.

Work begun March 2006
“Contentious project from the beginning”
AASHTO TCED
First look early 2008; not well received
“Final” draft much improved
Combined comments to contractor April 2009 TRB AFB-40 attempted to accomplish a comprehensive update through volunteer technical experts, 2000-2004. This effort failed due to the magnitude of the revision needed for the product to be useful in the current transportation environment. AFB-40 then developed and submitted an NCHRP problem statement in 2004 for funding in the 2005 cycle.
NCHRP - NCHRP accepted this project for funding in 2005 and the project began in December. Contentious project from the beginning. Many opinions from State DOTs and other stakeholders on the needed content. Significant stakeholder outreach occurred as the scope was refined. The primary work is complete, the NCHRP panel and TCED are awaiting final edits by the contractor.

27. 27 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
The committee is coordinating with the NCHRP project panel 15-33, updating/rewriting the 1991 Guide for Transportation Landscape and Environmental Design. We expect it to be ready for SCOD balloting in late 2009.
Additional major activities this committee is interested in participating in (they are currently just proposals):
Web-based guidance on new methods for retaining and using stormwater runoff in ROW (jointly with the TC on Hydrology/Hydraulics, not begun)
AASHTO’s CSS work and publications (not begun)
TRB Task Forces on CSS and Visualization (not begun)

29. 29 5-Year Goals
Retain multi-disciplinary membership
Gain exception from SCOH/SCOD rule which limits eligible Chairs of Technical Committees
Fill remaining vacancies
Gain approval for 1 additional Region 4 member
Share CSS activities
Publication updates
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. Committee’s 5 year goals:
The TCED is comprised of approximately 1/3 Design Engineers, 1/3 Landscape Architects, and 1/3 NEPA staff. This professional diversity serves TCED and AASHTO very well.
Gain exception to the recent SCOH/SCOD rules limiting eligible Chairs of Technical Committees, especially for the 3 TC’s, like TCED, that have multi-disciplinary membership. The TCED continues to believe all TC members should be eligible to serve as a TC Chair; TC members should have delegated authority to designate/elect any co-member as Chair.
TCED currently has 1 vacancy from Region 2. The current member states are Florida, South Carolina and West Virginia.
We currently have two vacancies from Region 3. One vacancy was created from the retirement of Win Stebbins from Michigan.
The current member states are Indiana and Iowa.
Allow 1 additional TCED membership from Region 4, which is Hawaii. Hawaii can only afford to attend one meeting per year due to obvious logistics. The other member states are California, Idaho, Utah and Wyoming.
Share CSS successes and problems with AASHTO/FHWA as TCED members’ DOTs implement and maintain CSS/CSD. About 6-8 TCED members are either their DOT CSS Coordinator or on their DOT CSS Team, and share their experiences at each TCED meeting.
