Urban imperviousness is an indicator determines the amount and spatial distribution of non-point source (NPS) pollutants from urban run-off. This paper applies numerous GIS functions (such as reclassify and zonal spatial analyst tools) and a GIS-based Utility (PLOAD) to model, analyze, and map out the NPS pollutants and distribution. As such an integrated land use and GIS modeling tool is developed to assess how built environment can be associated to addressing water quality issues.
