“…The detailed computational procedure can be found in the SUSTAIN manual [6] and is not given here. The optimization module helps users to test different LID designs in terms of cost and performance and to select the most cost-effective LID design and location [10]. However, the optimization module was not used in this study because local cost functions for LIDs are not available for Taiwan.…”

Low impact development (LID) has been widely accepted at lot-scale design but less so for watershed-scale cases because of the absence of appropriate assessment tools. The USEPA developed the System for Urban Stormwater Treatment and Analysis Integration Model (SUSTAIN) to evaluate the performance of LID practices at different spatial scales; however, the application of this model has been limited relative to the large number of LID cases. In this study, the SUSTAIN model was applied to a Taiwanese watershed to determine the feasibility of applying the model to international cases. Model calibration and verification were performed, and different types of LID facilities were evaluated. The results showed that infiltration was the dominant contribution to LID performance and that the plant intercept had a minor effect on the treatment. The number of units also influenced the overall performance.Increasing the number of LID units further decreased the pollution. The results of a watershed-scale simulation were used to rank the primary areas for nonpoint source pollution and to identify effective LID practices.

“…LID can also be targeted for expansion or alteration as required to address action plan "prepare and monitor" trigger points, such as those associated with increasing rainfall, increased population, land use changes, and more. LID is flexible, can be developed as necessary, can be quite cost effective (Saravanapavan et al, 2013), and can be easily combined with other stormwater management techniques to form a comprehensive regional and local strategy.LIDs can also generate benefits regarding other urban water managementissues, such as water availability (Walsh et al, 2012).However LID implementation requires the active involvement of a large number of property owners, raising new difficulties.…”

Managing urban stormwater is challenging under the best of situations, and due to projected increases in intensity of rainfall events is exacerbated by climate change. Institutional and individual aspects of urban stormwater management and the implications for low impact development (LID) are then presented. The paperframes stormwater as a "public good provision" issue in order to buildon existing knowledge about that kind of social dilemma. This topic is then examined in more detail through stakeholder interviews conducted in Somerville, Massachusetts, USA. Interviews were completed at a variety of management levels, from household to regional planning level, and are related back to the theory of public good provision. Finally, synthesis of theory and practice results in specific recommendations for urban stormwater management, based on revising thestormwater institutional framework, showcasing redevelopment opportunities, and facilitating education and awareness through local NGOs.

Low impact development (LID) is a relatively new concept in land use management that aims to maintain hydrological conditions at a predevelopment level without deteriorating water quality during land development. The United States Environmental Protection Agency (USEPA) developed the System for Urban Stormwater Treatment and Analysis Integration model (SUSTAIN) to evaluate the performance of LID practices at different spatial scales; however, the application of this model has been limited relative to LID modeling. In this study, the SUSTAIN model was applied to a Taiwanese watershed. Model calibration and verification were performed, and different types of LID facilities were evaluated. The model simulation process and the verified model parameters could be used in other cases. Four LID scenarios combining bioretention ponds, grass swales, and pervious pavements were designed based on the land characteristics. For the SUSTAIN OPEN ACCESSWater 2014, 6 3576 model simulation, the results showed that pollution reduction was mainly due to water quantity reduction, infiltration was the dominant mechanism and plant interception had a minor effect on the treatment. The simulation results were used to rank the primary areas for nonpoint source pollution and identify effective LID practices. In addition to the case study, a sensitivity analysis of the model parameters was performed, showing that the soil infiltration rate was the most sensitive parameter affecting the LID performance. The objectives of the study are to confirm the applicability of the SUSTAIN model and to assess the effectiveness of LID practices in the studied watershed.
