- Guidelines for evaluating and selecting modifications to existing roadway drainage infrastructure to improve water quality in ultra-urban areas / by GeoSyntec Consultants.(CARDINAL)309384; National Research Council (U.S.).Transportation Research Board.(CARDINAL)141287; National Cooperative Highway Research Program.(CARDINAL)281856; American Association of State Highway and Transportation Officials.(CARDINAL)138446; United States.Federal Highway Administration.(CARDINAL)139839;
Research sponsored by the American Association of State Highway and Transportation Officials in cooperation with the Federal Highway Administration"TRB's National Cooperative Highway Research Program (NCHRP) Report 728: Guidelines for Evaluating and Selecting Modifications to Existing Roadway Drainage Infrastructure to Improve Water Quality in Ultra-Urban Areas provides guidelines to evaluate and select hydraulic modifications to existing drainage infrastructure that will help mitigate potential impacts of highway runoff on receiving waters. The guidelines are directed specifically at roadway facilities in dense urban areas that can be particularly difficult and costly to retrofit because of space limitations, high pollutant loadings, hydrologic flashiness, hydraulic constraints, legacy contamination, utility conflicts, and other issues. The guidelines are accompanied by a Microsoft® Excel-based design and sizing tool on a CD-ROM included with the print version of the report. The tool generates best management practice (BMP) performance curves that relate the performance and design criteria for selected BMP controls described in the guidelines for each of the 15 U.S. rain zones. The Excel spreadsheet that is content on the CD-ROM is available for download."--Summary.Includes bibliographical references (pages 161-167).- Subjects: Technical reports.; Road drainage.; Urban runoff.;

Includes bibliographical references (page 37-41).Introduction -- Trenchless renewal methods -- Current practice and experience -- Conclusions -- Appendix A. Survey questionnaire -- Appendix B. Agencies responding to questionnaire.The Renewal of Stormwater Systems Using Trenchless Technologies summarizes technologies used for the renewal of stormwater systems, including new, emerging, and underutilized trenchless methods, and identifies future research needs. Both trenchless replacement and trenchless renewal methods can reduce negative impacts associated with surface disruption by moving the work area outside of the travel lanes and concentrating the construction impacts off the roadway. Trenchless renewal can extend the service life of existing stormwater facilities by addressing decay such as corrosion, abrasion, and erosion; reducing or eliminating infiltration and exfiltration; and providing a structural repair or improving the structural capacity of culverts, pipelines, manholes, and related stormwater structures. In some situations, trenchless renewal can even improve the hydraulic capacity of the stormwater system.Research sponsored by the American Association of State Highway and Transportation Officials in cooperation with the Federal Highway Administration- Subjects: Storm sewers; Trenchless construction; Urban runoff; Transportation agencies;
