However in analysis, staff modified the 0-75'zone calculation to include an <br /> estimated square footage of existing patio and flagstvne paver walkways within 75 feet of the <br /> lake which were not specificalfy calculated. Prior to placement on the City Counci) agenda the <br /> applicant should provide clarification as to the amount of hardcover existing and proposed <br /> within the 75-foot setback. <br /> ------------------------------------------------------------------------------------ <br /> lake and Average Lakeshare Setback Variances <br /> The average lakeshore setback line divides the home almost in half; all the proposed additions <br /> or changes are shown to be lakeward of the line therefore requiring an average lakeshore <br /> setback variance. Neighboring hames are over 400 feet away and are separated visually by <br /> exi5ting vegetation and/or topographic differences. The proposed one-story additions to the <br /> home will have minimal visual impact from the lake and will have minimal impact the existing <br /> views of the lake from the adjacent homes. <br /> Properties on Long Lake are subject to a 10�-foot setback for structures when served by private <br /> septic systems; a 75-foot setback is required for sewered properties. Currently the subject <br /> property is served by a private septic system. The property owners hope to connect to City <br /> sewer in the future; however, the current projects must be held the current setback <br /> requirement. 'Tfie existing home encroaches appraximately 14 feet ahead of the 7.00-foot <br /> setback line. The applicant's proposal includes modifying an existing octagonal room on the <br /> west sicle of the home to create a square roorn; this addition will be lakeward of the average <br /> lakeshore setback but will meet the 100-foot setback. The changes on the east side will result in <br /> the removal of a grade level deck to be replaced with a larger 14' x 23' enclosed addition <br /> completeiy within the average lakeshore setback and 100 foot lake setback. Finally, a pool is <br /> proposed to be constructed lalceward af the horne, approximately 50 feet from the OHWL and <br /> ahead of the average lakeshore setback, almost entirely within the 75-foot zone where no <br /> hardcover or structure is permitted. <br /> Hardcover Variance <br /> The portion of the application subject to a hardcover �ariance is the pool and pool patio <br /> surround within the 75-foot setback where hardcover is not is permitted. The pool is not an <br /> allowed hardcover encroachment within tfiis zone. <br /> Percinent Authority <br /> In reviewing applications for�ariance, the Planning Commission shalE cor�sider the effect af the <br /> proposed variance upon the health, safety and welfare of the community, existing and <br /> anticipated traffic conditions, light and air,danger of fire, risk to the public safety, and the effett <br />
