“…The initial construction cost (ICC) mainly includes the land, equipment and material costs, and excavation. 35 The initial construction components and unit costs used in this study are listed in Table 3. The monetary unit used in Table 3 is the RMB (in Chinese yuan), considering the currency exchange rate in 2022.…”

“…Costbenefit analysis, which aims to maximize the benefit while minimizing the investment, is the main method of investment decision. 33,34 Some cost-benefit analysis methods, such as the construction cost method [35][36][37] and the life cycle cost (LCC) method, 33,38,39 focus only on the cost impact of LID practices. The tools used to analyse the economic benefits of LID practices vary from life cycle cost models to cost-benefit analysis models.…”

“…A redução do volume escoado atenua a necessidade de implantação de estruturas de drenagem, possibilitando a redução da quantidade de materiais necessários para pavimentação de estradas e calçadas e para instalação de meios, calhas, sarjetas e redes de tubulações subterrâneas, reduzindo assim os custos com infraestrutura (EPA, 2007).…”

A concepção de infraestruturas sustentáveis, embora não nova, tem recebido crescente atenção nas políticas públicas devido ao crescimento urbano não planejado, atividades econômicas poluidoras e habitações precárias, resultando na subpriorização dessas infraestruturas. Isso tem levado a uma abordagem de "consertar depois", aumentando custos, como visto na drenagem urbana. O debate sobre sustentabilidade destaca os altos custos das infraestruturas tradicionais e a necessidade de soluções sustentáveis. Este artigo visa identificar os aspectos essenciais para promover infraestruturas sustentáveis no Brasil, especialmente no setor de saneamento, considerando o papel do Estado e a legislação internacional. Destaca-se a importância da gestão integrada baseada na dinâmica da natureza (Natural-Based Solutions) para prevenir desastres e promover soluções economicamente viáveis, oferecendo elementos para integrar políticas de saneamento, recursos hídricos, uso do solo urbano e prevenção de desastres. O texto discute a evolução das infraestruturas de drenagem, os investimentos públicos e políticas convergentes com o desenvolvimento sustentável, culminando em considerações finais sobre o tema.

“…Through these processes, pollutant concentrations of metals (zinc and copper), total suspended solids, total phosphorus, and total nitrogen have been reduced by more than 90% [76][77][78]. Capturing these contaminants at the source (i.e., upstream of the drainage point or outlets to rivers) prevents the contaminants from flowing downstream and also reduces the spread of contaminants within the watershed [79][80][81]. Thus, for this research, higher ENI 3 values were assigned to sites farthest from rivers as an indicator of "source control" to improve water quality in the rivers.…”

The primary goal of low impact development (LID) is to capture urban stormwater runoff; however, multiple indirect benefits (environmental and socioeconomic benefits) also exist (e.g., improvements to human health and decreased air pollution). Identifying sites with the highest demand or need for LID ensures the maximization of all benefits. This is a spatial decision-making problem that has not been widely addressed in the literature and was the focus of this research. Previous research has focused on finding feasible sites for installing LID, whilst only considering insufficient criteria which represent the benefits of LID (either neglecting the hydrological and hydraulic benefits or indirect benefits). This research considered the hydrological and hydraulic, environmental, and socioeconomic benefits of LID to identify sites with the highest demand for LID. Specifically, a geospatial framework was proposed that uses publicly available data, hydrological-hydraulic principles, and a simple additive weighting (SAW) method within a hierarchical decision-making model. Three indices were developed to determine the LID demand: (1) hydrological-hydraulic index (HHI), (2) socioeconomic index (SEI), and (3) environmental index (ENI). The HHI was developed based on a heuristic model using hydrological-hydraulic principles and validated against the results of a physical model, the Hydrologic Engineering Center-Hydrologic Modeling System model (HEC-HMS). The other two indices were generated using the SAW hierarchical model and then incorporated into the HHI index to generate the LID demand index (LIDDI). The framework was applied to the City of Toronto, yielding results that are validated against historical flooding records.
