Abstract: Washington State University (WSU) and project partners will complete the construction of the first university LID research program in the western US in 2010. The program will focus initially on the water quality treatment and flow control performance of permeable pavement and bioretention. The largest parking area on campus (impervious asphalt) was removed and replaced with pervious asphalt and concrete. A 0.24 ha (0.6 ac) gravel area adjacent to the parking lot was also removed and replaced with 39bioretention cells to assess development of soil characteristics, permeability over time, pollutant removal capability of various soil mixes, and plant performance. Two characteristics are unique to this installation. First, the permeable paving and bioretention research plots are full-scale and replicated. Second, the permeable pavement and bioretention systems can receive stormwater from natural storms delivered by gravity flow or synthetic stormwater can be blended and applied from cisterns at specific flow rates, volumes and pollutant concentrations.
