<br />Anderson, CUP <br />April 26, 1994 <br /> <br />') <br /> <br />"J <br /> <br />Page 2 <br /> <br />District were all notified of this proposal. At the time this memo was <br />written, the DNR and the Soil & Water Conservation District have replied. <br />Attached is a copy of their response for your review. No permits will be <br />required from either the DNR or the Soil & Water Conservation District. I <br />will update the Planning Commission regarding the response from the Army <br />Corps of Engineers, if available, at Tuesday night's meeting. <br /> <br />e <br /> <br />EROSION CONTROL <br /> <br />It is important to avoid erosion by making sure all disturbed areas be planted <br />with ground cover sufficient to contain the soil. Ground cover should be <br />tended as necessary until it is self sustaining, thereby reducing the chance <br />for excavated material to flow back into the wetland and degrade water <br />quality. Silt fencing should be used along the wetland boundaries until the <br />existing vegetation has a chance to take hold. <br /> <br />DRAINAGE <br /> <br />Terry Maurer, City Engineer, did not feel drainage would be a problem as <br />long as the excavated material would not be placed in an area which could A <br />disrupt existing drainage patterns. . <br /> <br />SLOPES <br /> <br />According to Elk River City Code, slopes can not be any steeper than 4 feet <br />horizontal to one foot vertical. For safety purposes, this is especially true of <br />excavated ponds. The actual depth of the pond should not be greater than 4 <br />to 5 feet to ensure that this pond will be safe in a residential area while <br />providing beneficial wildlife habitat. The outer edge of the excavated pond <br />should also be irregular, as this is enhancement for various types of wildlife. <br /> <br />EXCAVATED MATERIAL <br /> <br />All the excavated material will remain on site and be used for landscaping <br />purposes near the home. The 1991 Wetland Conservation Act prohibits any <br />of the excavated material to be placed back within the wetland boundaries, <br />therefore, all excavated material must be removed from the wetland itself. <br /> <br />RECOMMENDATION <br /> <br />Staff is recommending approval of the request by Brian Anderson to excavate <br />approximately 5,000 cubic yards of black dirt from a wetland to enhance <br />wildlife viewing with the following conditions: <br /> <br />e <br /> <br />anderson. planning <br />
