The site is located on an area delineated as a wetland. The site is located on the Lake <br /> Mendota Priority Watershed. The goals of the priority watershed for newly <br /> developing sites are 7.5 Vac/yr. soil erosion control. Due to the slopes, it is expected <br /> that soil loss will be a moderate concern, but the post development due to the <br /> proposed commercial land use will be the main concern and needs 80% pollutant <br /> reduction for post development. <br /> 2. The rezoning of the site is considered a sensitive area, due to the proximity to the <br /> Yahara River. <br /> 3. The water quality component should be addressed to prevent sediment, phosphorus <br /> and other pollutants from leaving the site. <br /> 4. 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 /> 5. The site contains a stream that drains to the Yahara River. Provisions to ensure <br /> protection to the stream need to be adressed. <br /> 6. The runoff control after development should be addressed to maintain the park 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 />
