1. Zoning File #1785 November 13, 1992 Page 3 proposes a realignment of all three properties whereby proposed Lots 2 and 3 will have lakeshore. The existing structure on Lot 3 will now meet the required 10' setback from the side lot line where structure had originally encroached into 610 Bi'^ Island approximately 1-2', The existing structure on Lot 2 is located approximately 4* from the newly proposed side lot line between Lots 2 and 3, Per Section 10.31, Subd, 18 (E), no setback can be reduced to less than 10'. The proposed lot line arrangment can not be approved unless applicant proposes the removal and replacement with a conforming structure. Refer to Exhibit F. Proposed Lot 1 provides applicant with higher and dryer elevations to north Increasing the building envelope. Based on lot widths, proposed Lot 1 will be required to meet a 30* interior lot line setback based on the 120' width measured at the Intersection of the side lot lines with the 75' setback line. Proposed Lots 2 and 3, because their lot widths are less than 100' in width, will be required to meet a 10' interior lot line setback. As proposed Lot 3 is located adjacent to a street at both the north lot line and the south lot line, a 30* setback would be required if new construction was proposed. The second part of the subdivision application involves the creation of easements for the purpose of sharing an on-site septic system. The drainfield area is to be located on proposed Lot 2 with tanks installed on proposed Lot 1. Please review Exhibit D, Weckman's memo, both Lots 1 and 2 are proposed for new construction with cabins having two bedrooms, bathrooms and kitchen sink. On-site sewage treatment is required. Test information confirms adequate area for a four bedroom mound system. A 10' setback variance will be required between the shared lot lines of proposed Lots 2 and 3 because septic tanks do not meet the required 20* setback from shared lot line. Each of the parcels will grant easements in favor of each other to allow the shared use and maintenance of the septic system. Weckman notes this is the only suitable area on both properties for septic use and that no alternate site is available but finds no problem as cabins are seasonal and would not be used to capacity for extended periods. The sharing of a septic system would not be in conflict with the MPCA or the City of Orono on-site septic standards. In fact, this may be a solution for several properties on Big Island where outhouses exist and do not conform to the required separation distance to OHWL - such as the outhouses on both of these properties. Staff has conditioned approval of this shared septic system based on the granting of mutual easements and subject to the limitation of the number of bedrooms to two for both properties. It is also suggested that covenants define location of test site on property in order to assure protection during construction and with future seasonal recreational use.
