R', <br />k'k. <br />Zoning File #1668 <br />September 1991 <br />Page 5 <br />1017.7 elevation. The northern drainageway at the 1017.9 <br />elevation would receive overflow but the major drainage would <br />extend to the east through the 1017,7 exit point. To be <br />consistent with the Minnehaha Creek Watershed District's first <br />review comments^ any excavation for the purpose of retention on <br />the site must be above the 1017.7 elevation. Baseo on the width <br />constraints along the east side of the property for the public <br />works needsr the excavation would have to be made to the west <br />side of the designated wetland area. This would require a <br />separate conditional use permit and variance review if the <br />excavation would be contiguous to the designated wetland «nd not <br />maintain the required 26' setback. There is also a need to <br />redefine the drainageways as the old drainage paths are <br />interspersed now with mature l.umroocks and other forms of natural <br />obstacles. Drainage easements will be taken over these <br />drainageways as 6ho%m on Exhibit H. <br />Steve McComas* a limnologist with the Bonestroo firm, was <br />asked to formally classify the type of wetlands. Mr. McComas has <br />made a complete inspection of the property and has confirmed the <br />wetland as a Type II. His final report will be sent to the MCWD <br />for their review and further consideration of the City's <br />application. Mr. McComas will also be asked to appear before the <br />Planning Ccxnmission if the City proposes a retention pond either <br />contiguous or within 26' of the designated wetland area requiring <br />a full variance review. <br />The Planning Commission adopted the staff's approval <br />racomirendation subject to Conditions 1-6. The enclosed <br />approval resolution has been amended per the recent drainage <br />Information. <br />Isv
