Green Stormwater Infrastructure Monitoring of Philadelphia’s Green City, Clean Waters Program

Post Construction Green Infrastructure Performance Monitoring Parameters and Their Functional Components

“…These three step processes in conjunction with the components of green infrastructure monitoring program (Figure 4) can be elaborated in each In general monitoring and evaluation of post-construction green infrastructure practices have three step processes. However, additional sub-questions shall be addressed in order to formulate a "well-organized" process see Figure 5 below [8,37,41,43,45]. These three step processes in conjunction with the components of green infrastructure monitoring program (Figure 4) can be elaborated in each step.…”

“…These three step processes in conjunction with the components of green infrastructure monitoring program (Figure 4) can be elaborated in each step. These steps are fundamentals to create accurate successful and well organize green infrastructure practices monitoring and evaluating programs [36,37,41,46]. Below are the range of supplemental sub questions that should be addressed to create accurate performance standards.…”

“…can be used to analyze, interpret, and draw conclusions. This allows decision makers to make informed decisions about how to adapt and make the necessary adjustments to the design of future green infrastructure practices [33][34][35][36][37][38][39]. However, a baseline mapping or threshold should be established and defined by the initial state of the Watershed (CSO's, MS4), or flooded areas before performing monitoring and assess the impacts and benefits of post constructed green infrastructure projects.…”

“…Variables are conditions that have an effect on the green infrastructure programs implementation, its functional performance as designed and maintain its functionality over time. These monitoring activities and their functional parameters can be varied by locations, physical settings, and types of the practices, materials, land use, land cover, policy/partnerships implementation strategies and community acceptance [21,37,43,[52][53][54]. For example, if the models set up to monitor the performance of post-constructed green infrastructure practice using quantitative variables such as rainfall and its functional components as hydrology and hydraulics in a particular watershed, model result should provide us information on flow quantities, qualities, and time of concentrations, what is the stormwater runoff flow pattern and how much are going to flow into green infrastructure practices?…”
