CIVIC-PG Track A: Assessing the Performance of Green Stormwater Infrastructure for Climate Adaptation and Coastal Resilience in the City of Cape Canaveral, Florida

该项目计划在佛罗里达州卡纳维拉尔角市建立一个城市水文监测网，通过参与性的特雷特进程。像许多沿海社区一样，卡纳维拉尔角面临着越来越大的洪水风险和近岸水域有害藻类大量繁殖的压力。建筑环境中陈旧的基础设施和加速的气候变化正在放大城市洪水和藻类大量繁殖的影响，导致对公共安全、生态系统健康和私人财产的威胁日益增加。卡纳维拉尔角市政府正与其学术和社区合作伙伴合作，计划设计、实施、监测和评估基于自然的绿色雨水基础设施(GSI)，作为缓解当前和未来这些压力来源的一种方法。这个GSI监测网络将为卡纳维拉尔角和佛罗里达州东部更广泛的印度河泻湖分水岭带来重要好处，同时也展示了在同样脆弱的沿海地区优化和评估GSI绩效的机会。GSI是指一套雨水管理实践，旨在维护、恢复和/或模拟已建成环境中开发前的水文条件。这些做法正越来越多地被作为降低洪水风险、改善水质、改善城市栖息地和创造宝贵的绿地便利设施的工具加以推广。然而，GSI尚未在美国大部分地区大规模采用，包括佛罗里达州沿海的大部分地区，在这些地区，现有的雨水基础设施系统在很大程度上不适应气候变化驱动的洪水风险，往往被视为受损的水生态系统的主要污染物负荷源。相对缺乏监测和性能数据，模糊的许可设计标准，以及误解的维护协议，都被普遍认为是在佛罗里达州和其他地方更广泛应用GSI的关键障碍。为了帮助克服这些障碍，卡纳维拉尔角积极作为一个应用研究项目的合作伙伴和东道主，该项目全面测试GSI干预措施的现场表现，以缓解当地严重的暴雨洪水和非点源养分负荷问题。全面实施的项目的主要研究目标包括表征雨水入渗率-容量、区域营养负荷减少性能，以及对GSI系统作为市政设施的公开评估。预计结果将促进在危险的印第安河泻湖分水岭进行更多的GSI研究和采用，该分水岭拥有150万人口，经常被描述为北美生物多样性最丰富的河口，并广泛影响世界各地城市化沿海社区的GSI监测实践的演变。该项目是对公民创新挑战计划的响应--Track A.生活在不断变化的气候中：围绕适应、恢复和缓解的灾前行动--是NSF、国土安全部和能源部的合作。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

This project plans to establish an urban hydrology monitoring network within the City of Cape Canaveral, Florida, through a participatory charrette process. Like many coastal communities, Cape Canaveral is confronted with the stressors of growing flood risk and harmful algal blooms in nearshore waters. A combination of antiquated infrastructure in the built environment and accelerating climate change is amplifying the impacts of both urban flooding and algal blooms, resulting in increasing threats to public safety, ecosystem health, and private property. The Cape Canaveral municipal government, in collaboration with its academic and community partners, is planning to design, implement, monitor, and assess nature-based green stormwater infrastructure (GSI) as an approach for mitigating these current and future stressors. This GSI monitoring network will provide important benefits for Cape Canaveral and the broader Indian River Lagoon watershed of eastern Florida, while also demonstrating opportunities for optimizing and assessing GSI performance in similarly vulnerable coastal locations. GSI refers to a set of stormwater management practices that are designed to maintain, restore, and/or mimic pre-development hydrologic conditions within built environments. These practices are being increasingly promoted as a tool for reducing flood risk, improving water quality, enhancing urban habitat, and creating valuable green space amenities. However, GSI has not yet been adopted at scale in much of the U.S., including areas – like much of coastal Florida – where existing stormwater infrastructure systems are largely maladapted to climate change-driven flood risks and often identified as a primary pollutant load source into impaired aquatic ecosystems. A relative lack of monitoring and performance data, ambiguous permitting design standards, and misunderstood maintenance protocols are all commonly cited as key barriers to the wider application of GSI, in Florida and elsewhere. To help overcome these barriers, Cape Canaveral is motivated to serve as a partner and host for an applied research program that comprehensively tests the field performance of GSI interventions for mitigating locally severe stormwater-based flooding and non-point nutrient load issues. Key research goals for the fully implemented project include characterization of stormwater infiltration rate-capacity, areal nutrient-load reduction performance, and public valuation of GSI systems as a municipal amenity. Results are anticipated to facilitate greater GSI research and adoption in the imperiled Indian River Lagoon watershed, home to 1.5 million people and often described as the most biodiverse estuary in North America, and broadly impact the evolution of GSI monitoring practices in urbanized coastal communities across the world. This project is in response to the Civic Innovation Challenge program—Track A. Living in a changing climate: pre-disaster action around adaptation, resilience, and mitigation—and is a collaboration between NSF, the Department of Homeland Security, and the Department of Energy.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
