Next‐Generation Stormwater Infrastructures: A Typology of Paradigms for Design and Operation

ABSTRACT The conventional approach to urban stormwater system design is deemed unsatisfactory, primarily due to its narrowly defined objective. Such a design approach is limited due to the amplified variability of stressors resulting from climate change, urbanization, and ecologically harmful resource use. Additionally, recent technological advancements are not yet adequately utilized. In this perspective piece, we aim to introduce and summarize design paradigms that are gaining traction within the context of next‐generation stormwater infrastructures. Each paradigm offers its own set of vision and goals. Here, we consider common values, trends, ideas, and real‐world practices in the stormwater management field. We first highlight the limitations of the conventional paradigm—it falls short of effectively addressing the increasing challenges associated with the planet's uncertain hydroclimatic future and the new integrated objectives of urban stormwater systems. To address these challenges, this paper presents a summary of paradigms, offering an expanded vocabulary that enables urban stormwater system designers to recognize future uncertainties in stormwater systems and extend their functionality. This encompasses concepts that deal with design in the face of uncertainties: stormwater systems' (1) robustness & resilience, (2) adaptability, and (3) characteristics of antifragility. Additionally, some paradigms recognize urban stormwater systems as an integral component of a comprehensive and integrated urban environment, encompassing concepts such as (4) sustainability and (5) multi‐functionality. Compiling the vocabulary of paradigms in one place and amplifying the discussion can potentially assist researchers, system designers, and decision‐makers in meaningfully broadening the scope of their design goals.
