    Rain gardens and bioswales are examples of detention ponds. Rain gardens are shallow, vegetated basins that are frequently installed adjacent to impermeable surfaces such as roads, sidewalks, and parking lots. A runoff inlet allows the stormwater to pool in the rain garden and then either slowly infiltrate into the ground or be absorbed by the vegetation (Yang, Dick, McCoy, Phelan, & Grewal, 2013). Bioswales…

    more than 100 years ago, its surface drainage system consists of a single surface drainage channel at its downstream basin (Smith et. al., 2005). Whole watershed comprises of about 98% of medium residential settlement and 2% of forest and woody wetlands. Moores Run is accompanied by two USGS stream flow gaging stations; USGS 01585230 at Radecke Avenue and USGS 01585225 at a tributary of Moores Run, near Todd Avenue (Figure 1). Major source of Moores Run flow is the surface run-off during storms.…

    the volume of water is unable to seep in to the ground efficiently and runoff is created. Runoff is when the water travels across the ground surface and flows in to storm drains, streams, or other direct routes to significant water sources. As researchers May, Horner, Karr, Mar, and Welch state, urban development increases the amount of impervious surfaces which, while it does not contribute to pollution, alters the physical behavior of water systems (May, Horner, Karr, Mar, & Welch, 1997).…

    This passage uses a lot of numerical data to clearly point out some possible influences that may be caused by the project. (e.g. “Development of the athletic complex will disturb approximately 68.5 acres and create 8.29 acres of new impervious surface.”).
