Suggested Revisions to WSDOT Manuals for Implementing Washington State Highway Runoff Water Quality Research Results

Description:

The Washington State Department of Transportation (WSDOT)/University of Washington Highway Runoff Water Quality research project, conducted from 1977 to 1982, produced a number of results of potential use to WSDOT. An effort was required to implement these results in the Department's procedures. One phase of implementation completed previously involved preparation of a guide for assessing the impacts of operating highways on aquatic ecosystems and training WSDOT personnel in its use. The present phase involved formulating decision criteria in a number of water quality problem areas of concern to WSDOT and determining the need for revisions to departmental documents for consistency with the research results and the new criteria. The results of this phase are presented in a two volume implementation manual and this document listing the suggested modifications to the WSDOT Design Manual, Highway Hydraulic Manual, Quality Standards for Highway Maintenance, and Maintenance Manual to reflect the results of the research and criteria development.
