Abstract:This report builds on recent FHWA manuals by expanding and presenting additional data, design criteria, and monitoring study results on ; stormwater best management practices (BMPs) implemented in ultra-urban areas. An extensive literature search was performed along ; with a comprehensive analysis of documented information currently available, with the focus on identifying new and successful ; technologies for ultra-urban areas. Factors used to identify ultra-urban BMP studies included: ; .. Limited space available for BMP implementation (less than 0.5 ha 1 ac) . . Drainage area imperviousness greater than 50 percent. . Property value of land more than $215 per square meter ($20 per square foot) . . Location of BMP in right-of-way (only available space) . Existence of build-out conditions at the site (lot-line to lot-line development) . ; The purpose of this report is to provide a planning-level review of the applicability and use of new and more traditional BMPs in ultra-urban ; areas. This report focuses on the unique characteristics specific to ultra-urban settings and provides specific guidance for selecting and ; siting stormwater management technologies. The information is structured in an informative, user-friendly format, with case studies ; highlighting examples of BMP monitoring throughout the country and tables illustrating the characteristics of each BMP to facilitate ; comparison and identification of specific technologies appropriate to a given site. BMP information is provided in fact sheets, which ; address applicability, effectiveness, siting and design, maintenance, and cost considerations. The report is organized into separate ; chapters that address ultra-urban considerations, BMP design information tailored to the ultra-urban environment, monitoring program ; design, and BMP selection.
