Zoning File #2329 January 13, 1998 Page 3Duplex Credit Implications <br />Zoning Code Sec. 10.20, Subd. 3 (I) allows one duple.x to be located on a single lot in the LR-lC-1 <br />zone as a conditional use upon application therefore, provided that the following conditions are met: <br />1. Public sanitary sewer service is available. <br />2. The lot is adjacent to a commercial or industrial district. <br />3. The duple.x is constructed within 200' of the commercial or industrial district. <br />These standards would be met by the current proposal. A duplex is (briefly) defined as a single <br />building on a single lot containing two separate dwelling units. The duplex CUP standards do niit <br />require a duple.x lot to meet double the area standards. <br />The Shoreland District requirements specify that any lot approved for duplex use shall be at least <br />135' in width and at least 26,000 s.f. in area if riparian, and at least 17,500 s.f. in area if non-riparian. <br />Both proposed lots meet the minimum area as established in the zoning district and Shoreland <br />standards. However, lot width and the 'back lot' status of the riparian lot stand out as potential <br />additional issues. <br />Back Lot Considerations <br />Applicant's sketch plan proposes a 30' wide outlet over the existing shared driveway serving the four <br />existing neighboring residences and the four proposed new dwelling units. This number of homes <br />being served far exceeds the City's three-unit threshold for requiring development of a full-fledged <br />roadway. Likewise, applicant's plan proposes a 12'-20' easement driveway providing access to the <br />proposed lakeshore duplex, which clearly is in conflict with many of the back lot ordinance <br />requirements in regards to access, i.e.: <br />11.30 Subd. 5C does not allow the creation of back lots which are accessed by <br />easement such as that proposed. <br />11.30 Subd. 5C(lc) disallow's a front/back lot division w'hen the residence structure <br />on a neighboring lot adjacent to the back lot is less distant from the access outlt than <br />the zoning district front setback standard. The adjacent residence to the east is within <br />3 feet of the p.oposed outlot, rather than the 30' required. <br />Subd. 5C(2b) requires the lot width of a back lot to meet the zoning district standard
