<br />Tom Wiley <br />July 18, 1994 <br /> <br />Page 2 <br /> <br />. <br /> <br />The Department of Natural Resources (DNR), U.S. Army Corps of Engineers, <br />and Sherburne County Soil and Water Conservation District have been <br />notified in regard to this project. <br /> <br />Sherburne County Soil and Water Conservation District mentioned that the <br />pond is defined as a wetland by the 1989 Federal Manual for Identifying and <br />Delineating Jurisdictional Wetlands. Concern was mentioned in regard to <br />draining and filling of the wetland area. Mr. Wiley only intends to excavate <br />the area around the pond and fill on a site outside the wetland boundaries. <br />At the time this report was completed, the DNR and Army Corps of <br />Engineers had not responded. <br /> <br />This wetland is under the jurisdiction of the Wetland Conservation Act <br />(W.C.A.). The City of Elk River is the local governmental unit implementing <br />that act. <br /> <br />EROSION CONTROL <br /> <br />. <br /> <br />Erosion around the wetland should be avoided and all disturbed areas should <br />be protected by planting sufficient ground cover to contain the soil. Ground <br />cover should be protected as necessary until self sustaining, thereby reducing <br />the chance for excavated material to flow back into the wetland and degrade <br />water quality. Silt fencing would aid the wetland boundaries until the <br />existing vegetation secures soil. <br /> <br />DRAINAGE <br /> <br />City Engineer Terry Maurer commented on this project and mentioned <br />concern about excavated soil draining back into the wetland area. After <br />reviewing the proposed site for the excavated soil, Mr. Maurer did not <br />anticipate problems that could disrupt existing drainage patterns. <br /> <br />SLOPE <br /> <br />According to City Code, slopes can not be greater than four (4) feet horizontal <br />to one (1) foot vertical. Mr. Wiley is proposing a five (5) to one (1) slope for <br />the pond area. <br /> <br />. <br /> <br />Currently, the pond is approximately six (6) feet in depth. Newly excavated <br />areas of pond should remain consistent in depth with the existing pond. If <br />depth of the excavated pond areas exceeds four (4) to five (5) feet, it becomes <br />less desirable for specific wildlife species to take advantage of the wetland <br />habitat. It also helps ensure that the pond is safe in a residential area. <br /> <br />wiley. troy <br />
