Conditional Use Permit, James Nordenstrom Page 2 <br /> May 18, 1993 <br /> • allow the surround property owners with some "say" in this <br /> process . <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 /> 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 /> 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 /> EROSION CONTROL <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 /> DRAINAGE <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 /> SLOPES <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 /> • <br />
