SRS RN: Sustainable and Equitable Urban Stream Corridors: Improving aesthetic, social, water quality, and ecological values of urban watersheds to achieve downstream rural benefits

城市流域和河流走廊向下游河流输出大量污染物。这些污染物包括杀虫剂、垃圾以及过多的沉积物和营养物。这些城市非点源污染物增加了下游处理饮用水的成本，并导致湖泊、水库和河口的藻类大量繁殖。许多城市正在重新考虑其城市河流走廊的目标，并相应地修改景观规划和建筑法规。一些城市重新开发了城市水道，作为视觉，娱乐和社会设施，并在此过程中改善了下游水质。这个探索性的项目问：有哪些可供选择的城市河流廊道管理模式可以为更广泛的社区提供更广泛的生态系统服务并改善下游水质？替代模式的社会、监管和工程障碍是什么？多元化的核心团队将招募城市雨水管理人员和利益相关者团体，共同重新构想城市河流走廊，为更广泛的城市居民提供更广泛的有价值的生态系统服务，并改善下游农村水生系统的功能。最终目标是制定一个进程，使广泛的行为者和利益攸关方聚集在一起，制定城市河流管理的新模式，为当地和下游居民提供公平的生态系统服务。这项规划赠款将通过促进讨论、创建协作科学网络以及整合和吸收与城市河流走廊管理相关的数据，为这一新模式奠定基础。城市河流问题涉及许多相互交织的水文、生态、工程、社会、经济和政治问题，这项工作将测试在沟通、感知和理解方面弥合学科鸿沟的方法。该奖项反映了NSF的法定使命，并被认为值得通过使用基金会的知识价值和更广泛的影响审查标准进行评估来支持。

Urban watersheds and stream corridors export large amounts of pollutants to downstream rivers. These pollutants include pesticides, trash, and excessive concentrations of sediment and nutrients. These urban non-point source pollutants increase the cost of treating drinking water downstream and contribute to algal blooms in lakes, reservoirs, and estuaries. Many cities are rethinking their goals for urban stream corridors and revising landscape plans and building codes accordingly. Some cities have redeveloped urban waterways as visual, recreational, and social amenities and have improved downstream water quality in the process. This exploratory project asks: What are alternative urban stream corridor management paradigms that would provide a wider range of ecosystem services for a broader spectrum of the community and improve downstream water quality? What are the social, regulatory, and engineering impediments to alternative paradigms?The diverse core team will recruit urban stormwater managers and stakeholder groups to come together to re-imagine urban stream corridors that can provide a wider range of valuable ecosystem services to a wider spectrum of urban residents and improve the function of downstream rural aquatic systems. The ultimate goal is to develop a process by which a broad cast of actors and stakeholders come together to develop new paradigms for urban stream management that provide equitable delivery of ecosystem services to local and downstream residents. This planning grant will lay the groundwork for this new paradigm by facilitating discussions, creating collaborative scientific networks, and integrating and assimilating data relevant to urban stream corridor management. Urban stream problems involve many intertwined hydrologic, ecologic, engineering, social, economic, and political issues, and this effort will test approaches for bridging disciplinary divides in communication, perception, and understanding.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.
