Urban Stormwater Management: Evolution of Process and Technology
Abstract The practice of urban stormwater management has evolved over the course of several decades. Initially, stormwater management concerned itself primarily with abating downstream flooding and was the sole domain of engineers. As the regulatory climate changed over time, so did design philosophy, along with the types of management practices, the computational methods, and the prominence of stormwater management as an integral part of the overall site planning process. The milestones of this evolution include the addition of stormwater quality treatment as a regulatory standard and, more recently, a focus on reducing the overall volume of runoff through the use of small-scale, distributed management practices (often under the banner of Low-Impact Development or Environmental Site Design). The volume reduction strategy, referred to as “runoff reduction,” has been adopted as a regulatory standard in some parts of the USA, along with new stormwater practice design specifications and computational methods. The approach demands that stormwater design reach beyond sole reliance on engineering, as the new best management practices (BMPs) include site design strategies that incorporate elements of soil science, horticulture, landscape architecture, and, importantly, site planning. These new strategies have certainly been elevated to prominence by virtue of the hydrologic benefits but also by the integration of stormwater management into Clean Water Act permits and Total Maximum Daily Loads (TMDLs) assigned to impaired urban streams and receiving waterbodies. This chapter will outline the evolution of stormwater management regulatory goals and the corresponding design strategies and include examples of how these approaches are changing the structural and nonstructural design of the urban landscape.
