RAPID: Sustainable Stormwater Technologies

1010131个月通过向纽约市公园和娱乐部(DPR)授予非NSF ARRA资金，创造了一个狭窄的机会窗口，以非常积极的时间尺度在全市范围内安装一个新的“绿色街道”网络。DPR使用“绿色街道”(Green Street)一词来指代在公共通行权内未充分利用的不透水表面上建造的特别工程的植被覆盖的交通岛、中间带和凸起。ARRA资金不能用于购置和安装一般事务绩效测量仪器，而且在一般事务建造后安装这种仪器是有问题的。需要的是在施工过程中进行安装。该仪器将能够获取真实城市环境中不同环境和雨水负荷条件下的雨量捕获率、污染分配和蒸发蒸腾的数据。快速拨款的目的是资助(1)在建造GS性能测量仪器期间快速安装，以及(2)涉及学生使用安装的仪器来获得目标数据以测试GS性能的特定假设的研究。需要检验的假设之一是，与未灌溉的基线相比，通过利用径流收集和GS，可以增加蒸发蒸腾率，从而最大限度地有益地利用本来不受欢迎的雨水径流。这些数据将非常重要，因为它们将帮助全国各地的自来水公司评估新的GS基础设施将在多大程度上比传统的雨水管理手段更具成本效益和可持续性。即将到来的数十亿美元的城市基础设施决策将对城市水环境产生数十年的影响。

1010131MontaltoA narrow time window of opportunity has been created by the award of non-NSF ARRA funds to the NYC Department of Parks and Recreation (DPR) to install a network of new "Green Streets" across the City on a very aggressive time scale. DPR uses the term "Green Streets" (GS) to denote specially engineered vegetated traffic islands, medians, and bump-outs constructed on underutilized impervious surfaces within the public right-of-way. The ARRA funds can not be used to acquire and install instrumentation for GS performance measurements, and installation of such instrumentation post GS construction is problematic. What is needed is installation during construction. The instrumentation will enable the acquisition of data on stormwater volume capture rates, pollution partitioning, and evaportranspiration under variable environmental and stormwater loading conditions in real urban settings. The purposes of the RAPID grant are to fund (1) fast-track installation during construction of instrumentation for GS performance measurement, and (2) research involving students using the installed instrumentation to obtain the targeted data to test specific hypotheses on GS performance. Among the hypotheses to be tested is that by utilizing runoff harvesting in conjunction with GS, evapotranspiration rates can be increased in comparison to un-irrigated baselines, thus maximizing beneficial use of otherwise undesirable stormwater runoff. These data will be important because they will help water utilities around the nation assess the extent to which new GS infrastructure will be more cost-effective and sustainable than traditional means of stormwater management. Upcoming "billion dollar" urban infrastructure decisions will be impacting the urban water environment for decades.
