The values presented in Tables 1 and 2 show the <br />estimated annual volume and pollutant load reductions based on the conceptual analysis, and <br />don’t include any site-specific constraints for individual developments within the AUAR area. <br /> <br />Potential Impact to Downstream Receiving Waters <br />The analysis within the AUAR area shows that the runoff volumes will be reduced by <br />approximately 70 percent for each of the three revised land use scenarios as compared to <br />existing conditions. This is achieved through implementing City of Lino Lakes, RCWD, and <br />NPDES volume reduction requirements. This reduction in runoff translates directly to the <br />reduction in pollutant loads shown in Table 2. <br /> <br />
