Abstract

ABSTRACT With increasing investment in infrastructure to address flooding, including green and grey solutions, there are challenges in selecting the type and location of infrastructure. This paper proposes a method to prioritize locations for stormwater infrastructure. Compared to prior work, it considers both green and grey infrastructure and enables detailed spatial analysis of a community. It uses quantitative measures and includes the multiple potential benefits of green versus grey infrastructure. The method is applied to the coastal county of Chatham County, GA, USA. Results show how the methodology is used to select green or grey infrastructure solutions and highlight locations that should be prioritized for infrastructure investment. Analyses accounting for uncertainties in future climate projections and population estimates are also conducted. The method includes local community characteristics, results in clear placement locations, and with decision-maker input, enables solutions to be adapted as stakeholder priorities evolve to increase community flood resilience.

社区规模的空间测绘，优先考虑绿色和灰色基础设施位置，以提高抗洪能力

摘要随着对基础设施的投资不断增加，包括绿色和灰色解决方案，在选择基础设施的类型和位置方面存在挑战。本文提出了一种确定雨水基础设施位置的方法。与之前的工作相比，它同时考虑了绿色和灰色基础设施，并能够对社区进行详细的空间分析。它采用了量化指标，包括绿色基础设施与灰色基础设施的多重潜在效益。该方法应用于美国乔治亚州查塔姆县的沿海县。结果显示了该方法如何用于选择绿色或灰色基础设施解决方案，并突出了应优先进行基础设施投资的地点。还对未来气候预测和人口估计中的不确定性进行了分析。该方法包括当地社区特征，产生明确的安置位置，并在决策者的投入下，使解决方案能够随着利益相关者优先事项的发展而进行调整，以提高社区的抗洪能力。

期刊介绍： Sustainable and Resilient Infrastructure is an interdisciplinary journal that focuses on the sustainable development of resilient communities. Sustainability is defined in relation to the ability of infrastructure to address the needs of the present without sacrificing the ability of future generations to meet their needs. Resilience is considered in relation to both natural hazards (like earthquakes, tsunami, hurricanes, cyclones, tornado, flooding and drought) and anthropogenic hazards (like human errors and malevolent attacks.) Resilience is taken to depend both on the performance of the built and modified natural environment and on the contextual characteristics of social, economic and political institutions. Sustainability and resilience are considered both for physical and non-physical infrastructure.
