The site is located on an area with highly erodible soil (PeC2, KrE2, BaC2). The site <br /> is located in the Sugar River Watershed. The goals of sediment reduction for <br /> developing sites in this area are 15 t/ac/yr of soil loss. Due to the slopes, it is <br /> expected that soil loss will be a very important concern. Also, the post development, <br /> due to the proposed commercial land use, will be the main concern for peak flows and <br /> needs 80% pollutant reduction in sediment for post development. <br /> 2. The water quality component should be addressed to prevent sediment, phosphorus <br /> and other pollutants from leaving the site. <br /> 3. Detailed Erosion Control Plan should include temporary and long-term sediment <br /> control. The plan should also include long-term sediment, phosphorus, zinc, and <br /> copper. <br /> 4. The runoff control after development should be addressed to maintain the peak flows <br /> and times of concentration to pre-development condition and to reduce pollutants <br /> according to the post development concerns. High density residential areas increase <br /> runoff. The post development curve number for this type of land use is 98. <br /> AR aw <br />
