Second, the wetlands which would be disturbed and mitigated were studied as part of the COE permit. <br />6. River Protection <br />As is seen by the river location near the pit, there is a sharp outside bend in the river very near the <br />proposed pit. Although the pit will maintain a minimum 100' buffer from the toe of low water in the <br />river to the edge of excavation, embankment protection for this azea of the river is still warranted <br />for long term stability. This will ensure that the river never erodes into the lake during a lazge flow <br />event. <br />Therefore, a minimum durable rock size of 5' diameter is specified for a length of 225 feet and a <br />slope length of 16 feet as shown in the diagram below. The landowner has in the past placed many <br />lazge rock and concrete slabs of this approximate size in a portion of this area. This has provided <br />good protection but more material is needed laterally and vertically. The maximum slope of the em- <br />bankrnentwill be 2H I V. <br />"rbP OF BANK <br />North Fork Pit Mazch 04 25 <br />
