Environmental stewardship practice at state Departments of Transportation (DOTs)
has grown exponentially in recent years. NCHRP 25-25(04) presents a compendium of
environmental stewardship practices in construction and maintenance, developed from
the literature, state transportation agency manuals and procedures, and the contributions
of state DOTs and practitioners. The best practices herein serve as a guide to the
development of Environmental Management Systems and environmental strategic plans
both on the organizational level and in specific functional areas. Practices can
also serve as foundational elements for individual environmental guidance resources
that DOTs may develop.

The research reported herein was performed under NCHRP Project 25-25(04) by Venner
Consulting of Littleton Colorado as a subcontract to Parsons Brinkerhoff Quade and
Douglas. Hal Kassoff of Parsons Brinkerhoff serves as PB's Principal Investigator
for the NCHRP 25-25 series. Marie Venner served as Principal Investigator for this
project and authored/edited the report with editing assistance from Lisa Zeimer
of Parsons Brinckerhoff. Many state transportation agencies contributed to the collection
of these practices for this report and the AASHTO Subcommittees on Construction
and Maintenance participated in review of the compendium and addition of further
exemplary practices. The author wishes to acknowledge their generosity and invaluable
assistance, without which this project would not have been possible.
