#15-3789 November 19, 2015 Page 2 of 4 Revised Survey Impacts Due to a lack of detail with regard to contour lines and the OHWL with the initially submitted survey, applicant was directed to submit an update corrected survey prior to Council review. The new survey (Exhibit A) reveals that a portion of the existing house is located less than 75 feet from the 929.4’ OHWL contour, and encroaches past the defined average lakeshore setback line. The result of this is that: 1) The house cannot be moved further west to increase the east side setback without encroaching further past the 75’ lakeshore setback; 2) Rebuilding on the same footprint but in a different massing configuration requires a lake setback variance; 3) The proposed lakeside deck has been relocated further eastward than originally intended (see Exhibit B) but still includes an encroachment of the newly defined lake setback and average setback lines.

(25 %) 2,832 s.f. (20.3 %) 3,094 s.f. (22.2 %) Planning Commission Recommendation The Planning Commission voted 4 to 0 to approve the variances to street and side setbacks in order to rebuild on the existing footprint. Planning Commission did not have the new information that confirms the need for lakeshore setback and average lakeshore setback variances, and therefore has not made a recommendation on those two variances.
