“…In addition, the results implicate that the cost of installation of LID BMPs is affordable, easy to maintain, and offers various other environmental benefits to the community. These findings are similar to other research using the Green Values Calculator who also found long term economic benefits and stormwater reduction [40], [41], [42], [47]. …”

“…The National Green Values Calculator is an online tool developed to compare costs, benefits, and performance of GI compared to conventional stormwater management practices [39]. It has been used to assess the impact of stormwater management practices on water quality [40], adaptive capacity [41], runoff capture [42], and GI impacts on new housing [43], Using the calculators formulas, the total runoff reduction due to the LID retrofit design was calculated. Table 1 shows the input data used from Sugarland’s site characteristics into the National Green Values Calculator.…”

Climate change and its related factors are increasing the frequency of hurricanes, coastal storms, and urban flooding. Recovery from disasters can be slow, with jurisdictions failing to build back better, wasting time and money without improving resilience to the next disaster. To help attenuate floods and mitigate their impacts, Low Impact Development (LID) and the incorporation of green infrastructure (GI) is gaining in popularity. LID installs more natural methods of absorbing, redirecting, retaining, and filtering water, through GI installations such as rain gardens, detention ponds, and the reduction of impervious surfaces. LID is, however, primarily implemented and evaluated only on a local scale; few studies have assessed the broader impacts of GI on a larger scale. In fact, most performance calculators that evaluate the effects of GI are only useful at the site scale. Further, most advocates of GI propose its use in new developments, without much attention to retrofitting existing, suburban development. This article seeks to determine what the potential effects of retrofitting an existing, suburban neighborhood with GI for flood protection at a larger scale could be, using Sugar Land, Texas, USA as a case site. First, low-impact facilities are proposed and schematically designed at a site scale for a typical single-family lot. The volume of rainfall that can be retained on site, due to each incorporated feature, is then derived using the Green Values National Storm Water Management Calculator. Using this data, the total volume of rainfall that could be retained if all residential sites in Sugar Land incorporate similar facilities is then projected. The result show that Sugar Land has the capacity to capture 56 billion liters of stormwater water annually if all residential properties use LID. Additional benefits of the use of GI include reduced heat (37%), improved aesthetics and property values (20%), increased recreational opportunities (18%), improved water quality (12%), improved air quality (5%), increased green collar jobs (4%), reduced damage from harmful gas emissions (3%), and increased energy savings (1%), thereby surpassing conventional storm water management techniques [1].

“…Watershed‐scale models that use the Soil Conservation Service (SCS) curve number (United States Department of Agriculture, ) approach (e.g., LTHIA‐LID) simulate SCM function by modifying the curve number to lengthen travel time and increase initial abstraction. Hydrological modelling has been also used to optimize type, location, size, and cost of SCMs (Baek et al, ; Endreny & Collins, ; Gilroy & McCuen, ; Liu et al, ; Xing et al, ). More complex numerical models (e.g., HYDRUS and FEFLOW), based on Richards' unsaturated flow model coupled with soil hydraulic functions, are able to describe subsurface flow; however, the amount of input data and computational effort exceed that of approaches described above.…”

“…A variety of model types has been used that simulate hydrologic flowpaths and pollutant removal efficiency with a range of numerical approaches (e.g., process-based vs. stochastic). For example, the stormwater management model (Rossman & Huber, 2016) has been also used to optimize type, location, size, and cost of SCMs (Baek et al, 2015;Endreny & Collins, 2009;Gilroy & McCuen, 2009;Liu et al, 2016;Xing et al, 2016).

Deleterious effects of urban stormwater are widely recognized. In several countries, regulations have been put into place to improve the conditions of receiving water bodies, but planning and engineering of stormwater control is typically carried out at smaller scales. Quantifying cumulative effectiveness of many stormwater control measures on a watershed scale is critical to understanding how small‐scale practices translate to urban river health. We review 100 empirical and modelling studies of stormwater management effectiveness at the watershed scale in diverse physiographic settings. Effects of networks with stormwater control measures (SCMs) that promote infiltration and harvest have been more intensively studied than have detention‐based SCM networks. Studies of peak flows and flow volumes are common, whereas baseflow, groundwater recharge, and evapotranspiration have received comparatively little attention. Export of nutrients and suspended sediments have been the primary water quality focus in the United States, whereas metals, particularly those associated with sediments, have received greater attention in Europe and Australia. Often, quantifying cumulative effects of stormwater management is complicated by needing to separate its signal from the signal of urbanization itself, innate watershed characteristics that lead to a range of hydrologic and water quality responses, and the varying functions of multiple types of SCMs. Biases in geographic distribution of study areas, and size and impervious surface cover of watersheds studied also limit our understanding of responses. We propose hysteretic trajectories for how watershed function responds to increasing imperviousness and stormwater management. Even where impervious area is treated with SCMs, watershed function may not be restored to its predevelopment condition because of the lack of treatment of all stormwater generated from impervious surfaces; non‐additive effects of individual SCMs; and persistence of urban effects beyond impervious surfaces. In most cases, pollutant load decreases largely result from run‐off reductions rather than lowered solute or particulate concentrations. Understanding interactions between natural and built landscapes, including stormwater management strategies, is critical for successfully managing detrimental impacts of stormwater at the watershed scale.
