This report explores practices for the reduction of stormwater volumes in urban highway environments. The report outlines a five-step process for the identification, evaluation, and design of solutions for runoff volume reduction based on site-specific conditions. The manual also includes a set of volume reduction approach fact sheets and a user guide for the Volume Performance Tool. NCHRP Web Only Document 209 (at: http://www.trb.org/Main/Blurbs/172417.aspx): Volume Reduction of Highway Runoff in Urban Areas: Final Report and NCHRP Report 802 Appendices C through F explores the research developed for this report to help achieve surface runoff volume reduction of highway runoff in urban areas. The report is accompanied by a CD-ROM that contains a tool to estimate the performance of volume reduction. The CD-ROM is also available for download from TRB’s website as an ISO image at http://onlinepubs.trb.org/onlinepubs/nchrp/nchrp_rpt_802.iso. (Author/publisher) SWOV employees can access the CD-ROM here: http://bibliotheek.wp.swov.nl/pdfs/CRP_CD_162
