Mounds View Stormwater Pond Assessment <br />4 RECOMMENDATIONS <br />July 2023 <br />Table 4.3 Sediment Sampling for High and Medium Priority Ponds <br />AA-1.131 H 0.92 2 <br />$4,300 Collected at random or along transect <br />from inlet to outlet. <br />$4,300 <br />AA-1.132 H 0.58 2 <br />Collected at random or along transect <br />from inlet to outlet. <br />$4,300 Collected at random or along transect <br />EW-11.131 H 0.89 2 <br />from inlet to outlet. <br />EW-11.P3 I H 0.07 <br />GF-4.P2 H 0.15 <br />SC-2. <br />H <br />0.22 <br />SC-2.P2 H <br />0.19 <br />$4,300 Collected at random or along transect <br />from inlet to outlet. <br />$4,300 Collected at random or along transect <br />from inlet to outlet. <br />$4,300 Collected at random or along transect <br />from inlet to outlet. <br />$4,300 Collected at random or along transect <br />from inlet to outlet. <br />$4,300 Collected at random or along transect <br />SC-4.123 M 0.09 2 from inlet to outlet. <br />EW-4.P4 Collected within each acre of each of <br />Silver L 11.77 12 $10,150 the three bays at random or along <br />View* transect from inlet to outlet. <br />The dredging cost estimates provided in Section 4.3 assume Level 2 sediment for disposal management. <br />Costs will be updated following the sediment characterization. <br />It is recommended that all ponds be tested within a year of dredging for accurate contamination <br />characterization. Please note that the cost of sediment sampling is based on sampling ponds individually; <br />the cost will be reduced if ponds can be grouped and sampled on the same day. <br />*Silver View Pond was included as a line item in case the City would like to get an idea of how much <br />disposal would cost for future planning. Additional sediment testing would be required again within a year <br />before dredging. <br />AA-1.P1 and AA-1.P2 ponds sediments were sampled and summarized in a memo which can be found in <br />Appendix D. <br />24 <br />
