This report presents guidance for practitioners in assessing the impacts of bridge deck runoff on receiving waters and, if necessary, identifying the most appropriate method of mitigation as part of an overall management plan. This volume, Volume 2, presents the assessment process that was developed on the basis of the findings in the final report (Volume 1). This volume is the Practitioner's Handbook. It guides the user through a step-by-step process that begins with the collection of some basic data and the identification of the main areas of concern. Following these initial steps, the Handbook helps the user select the most appropriate analysis method, conduct an assessment of the results, and develop a management plan. Use of the Handbook and accompanying final report should be particularly helpful for practitioners (especially those responsible for structural, hydraulic, and water quality design and evaluation) in making sound, scientifically defensible decisions concerning the need for water runoff controls on new, replacement, or existing structures. |
