Nabueth <br />August 9, 1982 <br />s: <br />#693 Theron Hineline, 1565 Orono Oaks Drive - <br />Conditional Use Permit + Variance <br />t : • , ■■ <br />Application <• Conditional Use Permit 4> Variance required to <br />dredge wetland and create wildlife pond <br />Action Required - Planning Commission to act on application - <br />all property owners within 300 ft have been <br />notified. <br />Planning Commission should review the following pages of the CMP <br />Environmental Section <br />Map 4, CMP 3-4, 3-5, 3-16, 3-17, 3-18, 3-19 (Policies 3,4,5,6 & 7) <br />3-23 (Policies 1 & 3) <br />List of Exhibits <br />Exhibit A - Engineer's letter <br />Exhibit B - Planning Commission minutes July 19, 1982 <br />Exhibit C - Property Owners List <br />In rovioi/ of tho englnoor's report, tho proposed alterations c:? <br />the wetlands will not alter the drainage characteristics of the <br />Watershed - storage capacity will not be increased nor will it <br />be decreased. Clearly if the wetland is converted to a wildlife <br />pond that must contain standing water of a minimum 3* depth, <br />there will be drastic changes in the aquatic vegetation and the <br />assimilative rate. <br />The CMP finds limiting urbanization of the rural areas of the <br />watershed to be the key factor in controlling quality of water. <br />Aquatic vegetation in wetlands or marshes has been found to <br />function only during summer months because of the freezing winter <br />tesqieratures, much of the filtration value of the natural marsh <br />process is lost during the annual spring snow melt. It further <br />notes that marshes that have dryer areas, which have water in <br />them only interimittently, absorb a greater amount of phosphorous <br />and have an assimilative rate of 20 Ibs/acro/year as opposed to <br />marshes with permanent standing water with an assimilative capacity <br />of 4 Ib/acre/year. <br />I have been in contact wxtn Clifford Reap of the M.C.W.D. who <br />advises that if approved by the City a permit would be required. <br />I gathered from talking with Reep that they would follow the <br />guidelines of the DNR. <br />1
