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

像许多沿海社区一样，佛罗里达州的卡纳维拉尔角市面临着沿海洪水和近岸水域有害藻华(HABS)的压力。建筑环境中陈旧的基础设施和加速的气候变化共同放大了这些威胁，对公共安全、生态系统健康和私人财产产生了有害影响。卡纳维拉尔角市政府与其学术和社区合作伙伴合作，已将基于绿色雨水基础设施(GSI)的干预措施确定为其缓解气候和水质的主要战略之一。这个智能互联社区公民创新挑战全奖(SCC-CIRITY-FA)项目将在卡纳维拉尔角的退伍军人纪念公园建立一个GSI生物礁试点和相关的水文监测系统。这项试点的绩效数据将直接用于指导卡纳维拉尔角和佛罗里达州东部印第安河泻湖分水岭其他类似情况的沿海社区后续GSI项目的设计、实施和监测协议。这包括卡纳维拉尔角最近制定了一项雄心勃勃的25年总体规划，在总统街附近进行GSI干预，总统街是最近暴雨洪水事件的热点。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。这些做法被广泛推广为降低洪水风险、改善水质和创造有价值的绿地设施的工具。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，往往被确定为主要污染物负荷源。相对缺乏监测和性能数据、不明确的许可设计标准以及对维护协议的误解，这些都是GSI更广泛应用的关键障碍。为了帮助克服这些障碍，卡纳维拉尔角积极作为这一试点项目的合作伙伴和东道主，该项目将客观地测试GSI干预措施在缓解暴雨洪水和非点源养分负荷问题方面的实地表现。预计项目结果将影响更广泛的市政考虑，以及在高度受损的印度河泻湖的分水岭内采取适当的GSI干预措施。印第安河泻湖是160万人的家园，经常被描述为北美生物多样性最丰富的河口。公民创新挑战是与能源部、国土安全部和国家科学基金会的合作。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。

Like many coastal communities, the City of Cape Canaveral, Florida is confronted with the stressors of coastal flooding and harmful algal blooms (HABs) in nearshore waters. Antiquated infrastructure in the built environment and accelerating climate change are together amplifying these threats, with deleterious impacts to public safety, ecosystem health, and private property. The Cape Canaveral municipal government – in collaboration with its academic and community partners – has identified green stormwater infrastructure (GSI) based interventions as one of its primary strategies for climate and water quality mitigation. This Smart and Connected Communities Civic Innovation Challenge Full Award (SCC-CIVIC-FA) project will establish a pilot GSI bioswale and associated hydrologic monitoring system at Veterans Memorial Park in the City of Cape Canaveral. Performance data from this pilot will directly used to guide design, implementation, and monitoring protocols within subsequent GSI projects in Cape Canaveral and other similarly situated coastal communities in the Indian River Lagoon watershed of eastern Florida. This includes Cape Canaveral’s recent development of an ambitious 25-year master plan for GSI interventions within its Presidential Streets neighborhood, a hotspot for recent stormwater flooding events. 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 widely promoted as a tool for reducing flood risk, improving water quality, 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. 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. To help overcome these barriers, Cape Canaveral is motivated to serve as a partner and host for this pilot project that will objectively test the field performance of GSI interventions for mitigating stormwater-based flooding and non-point nutrient load issues. Project results are anticipated to influence broader municipal consideration and adoption of suitable GSI interventions within the watershed of the highly impaired Indian River Lagoon, home to 1.6 million people and often described as the most biodiverse estuary in North America.The CIVIC Innovation Challenge is a collaboration with Department of Energy, Department of Homeland Security, and the National Science FoundationThis 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.
