<br />Conditional Use Permit, James Nordenstrom <br />May 18, 1993 <br /> <br />Page 2 <br /> <br />allow the surround property owners with some "say" in this <br />process. <br /> <br />The applicant has proposed to excavate 7,500 cubic yards of <br />fill from a 260x150 foot low land area that is part of a <br />drainage and utility easement. All of the excavated black dirt <br />will remain on site and will be used for landscaping purposes <br />around the home. I have attached a site plan/survey which <br />shows the location of the proposed excavation area. <br /> <br />The DNR, Army Corps of Engineers, and the Sherburne County Soil <br />and Water District were all notified of this proposal. At the <br />time this memo was written, only Dale Homuth of the DNR had <br />sent a response regarding this project. Included is a copy of <br />Mr. Homuth's letter for your review. In the letter, Mr. Homuth <br />points out that DNR approval is not required for this issue <br />because it is not a public water wetland and no permit from the <br />DNR will be required. <br /> <br />I will update the Planning Commission regarding responses from <br />the Army Corps of Engineers and the Sherburne County Soil and <br />Water District, if they are available, at the Tuesday night <br />meeting. <br /> <br />EROSION CONTROL <br /> <br />It is important to avoid erosion by making sure all exposed <br />ground areas shall be planted with ground cover sufficient to <br />contain the soil. Ground cover should be tended as necessary <br />until the ground cover is self sustaining, thereby reducing the <br />chance for excavated material to flow back into the wetland and <br />degrade water quality. <br /> <br />DRAINAGE <br /> <br />Terry Maurer, City Engineer, reviewed this proposal and did not <br />feel drainage would be a problem as long as the excavated <br />material would not be placed in an area which could disrupt <br />existing drainage patterns. <br /> <br />SLOPES <br /> <br />According to Elk River City Code, slopes can not be any steeper <br />than 4 foot horizontal to 1 foot vertical. For safety purposes, <br />this is especially true of excavated ponds. The actual depth <br />of the pond should not be greater than 4-5 feet to ensure to <br />the greatest extent possible that this pond will be safe in a <br />residential area while providing beneficial wildlife habitat. <br />
