Identification of research needs related to highway runoff management.

This report presents an analysis of research needs in the area of highway water runoff management and control. Research directors and water-quality professionals from state departments of transportation (DOTs) participated in a survey to identify pressing needs related to the impacts and control of stormwater runoff. The survey results were supplemented with an extensive literature review and analysis by the research team. This report will be of great value in formulating high-priority research efforts at the national, state, and local levels.
