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.

该项目计划通过参与性专家研讨会在佛罗里达州卡纳维拉尔角市建立一个城市水文监测网络，与许多沿海社区一样，卡纳维拉尔角也面临着近岸水域日益增长的洪水风险和有害藻华的压力。建筑环境中陈旧的基础设施和加速的气候变化相结合，加剧了城市洪水和藻华的影响，导致对卡纳维拉尔角的公共安全、生态系统健康和私人财产的威胁日益增加。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），作为缓解这些当前和未来压力源的方法。该 GSI 监测网络将提供重要的信息。为卡纳维拉尔角和佛罗里达州东部更广泛的印第安河泻湖流域带来好处，同时也展示了在类似脆弱的沿海地区优化和评估 GSI 绩效的机会 GSI 是指一套旨在维护、恢复和/或恢复的雨水管理实践。或模仿这些做法被越来越多地推广为减少洪水风险、改善水质、改善城市栖息地和创造有价值的绿色空间设施的工具。美国的大部分地区，包括佛罗里达州沿海地区，现有的雨水基础设施系统在很大程度上无法适应气候变化驱动的洪水风险，并且经常被认为是受损水生生态系统的主要污染物负荷源。相对缺乏监测和性能数据。 ， 模糊的允许的设计标准和被误解的维护协议通常被认为是 GSI 在佛罗里达州和其他地方广泛应用的主要障碍。为了帮助克服这些障碍，卡纳维拉尔角有动力成为应用研究项目的合作伙伴和主办方。全面测试 GSI 干预措施的现场性能，以减轻当地严重的雨水洪水和非点养分负荷问题。全面实施的项目的关键研究目标包括雨水渗透率能力、面积养分负荷的表征。预计结果将促进在濒危的印第安河泻湖流域进行更多的 GSI 研究和采用，该流域拥有 150 万人口，通常被称为北美生物多样性最丰富的河口。广泛影响世界各地城市化沿海社区 GSI 监测实践的演变 该项目是为了响应公民创新挑战计划 - 轨道 A。生活在不断变化的气候中：围绕适应的灾前行动，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。
