< • f #2340 - Robert & Iris Waade May 21,1998 Page 3 location of the road within Outlot A has been shifted to the west side of the Outlot, leaving a 17 setback to the adjacent garage structure. Outlot B does not meet the 30' width requirement and requires a variance, and use of Outlot B to serve as access to all three units does not meet code standards. At least one of the units must have its access other than Outlot B or a variance would be necessary. It appears that this can be accomplished without causing a hardcover overage. Also, Oultlot B does not extend to the defined rear (south) line of Lot 1, creating a 'flag' lot which requires a variance per Section 11.31 Subd. 5C. Outlot C is being provided at the request of Hennepin County Public Works for needed sight distance improvements and added right-of-way at this location. The hill along North Shore Drive needs to be cut down to provide adequate sight distance. This excavation would be the responsibility of the developer. Grading & Drainage Plan The revised grading plan was submitted prior to the road relocation and duplex size reduction, and does not reflect those changes. This most current grading plan has been reviewed by the City Engineer, and his comments appear in Exhibit C, summarized as follows: 1. If pond reaches overflow elevation (i.e. if normal outlet pipe is plugged or a huge storm hits) it will overflow eastward, affecting neighboring properties. This should (and probably can) be revised to avoid such routing. 2. The grading plan reduces potential surface storm ponding for easterly lots, hence while total area draining to east is reduced, its storage potential is also reduced. A greater concern is that if stormwater from the east overflowed into this property prior to this development, it will now be blocked. This issue needs further detailed review before the drainage plans can be approved. It is likely that an analysis of the immediate watershed is necessary. t 3. A revised grading and drainage plan reflecting the road nnd duplex changes should be submitted. Some pond outlet details are needed. Staff and the city Engineer are scheduled to meet with the applicant on V .y 26 to review grading and drainage issues. Berm The grading plan proposes a berm approximately 2-3' above existing grades and 15' in vddth along the west lot line abutting Lakeside Marina. At the Planning Commis.«ic" meeting on May 18, HIM il
