Mounds View Stormwater Pond Assessment <br />4 RECOMMENDATIONS <br />July 2023 <br />4 RECOMMENDATIONS <br />Based on the basin analysis, we have identified recommendations for maintenance activities, sediment <br />sampling, assessment and restoration activities, and additional analysis. <br />4.1 DREDGING <br />4.1.1 PRIORITIZATION <br />Dredging priority was determined based on the current sedimentation levels and the rate of sediment <br />accumulation. Dredging is recommended for basins when greater than 50% of the storage volume is <br />filled. Dredging priority was divided into three categories: High, Medium, and Low. <br />High priority was given to basins in which dredging is recommended within the next five years. <br />• Medium priority was given to basins in which dredging is recommended within the next six to ten <br />years. <br />• Low priority was assigned to basins in which dredging is not recommended within the next ten <br />years. <br />Sedimental delta priority was determined based on pond surveys and field observations and also divided <br />into High, Medium, and Low categories: <br />High: Sediment delta is likely impacting pond performance. <br />• Medium: Sediment delta is not currently impacting pond performance but should be monitored <br />closely. <br />• Low: Sediment delta is present but not impacting pond performance and not a concern. <br />Dredging and sediment delta prioritizations can be found in Table 4.1. <br />19 <br />
