This is noted on <br />the preliminary plat and shall be noted on the certificate of survey submitted with the building <br />permit. <br /> <br />OHWL Setback <br /> <br />The required setback from the OHWL is 75 feet; however, Section 1102.07(2)(a) of the <br />Overlay District provisions states “Where structures exist on the adjoining lots on both sides of <br />a proposed building site, structure setbacks may be altered without a variance to conform to the <br />adjoining setbacks from the ordinary high water level, provided the proposed building site is <br />not located in a shore impact zone.” <br /> <br />The OHWL setback from the existing house on the proposed Lot 1 is 54.8 feet and the OHWL <br />setback on the adjoining parcel to the south, 6770 West Shadow Lake Drive, is approximately <br />67 feet. The average OHWL setback for Lot 2 is then 60.9 feet. The preliminary plat shows a <br />OHWL building setback line on Lot 2 extending from the house structures on Lot 1 and 6770 <br />West Shadow Lake Drive that is a minimum of 65 feet from the OHWL. The proposed house <br />on Lot 2 is setback 78 feet from the OHWL. This is compliant with both the required and <br />average setback. <br /> <br />Variances <br /> <br />Variances are required for lot size and street setback. <br /> <br />Lot Size <br /> <br />The required minimum lot size for riparian shoreland parcels is 20,000 sf. The larger lots <br />promote less intense development along lakes and provide additional surface area to minimize <br />the amount of stormwater runoff impacts into the public waters. Per Section 1102.07(1)(c)1 of <br />the Overlay District provisions: Only land above the ordinary high water level (OHWL) of <br />public waters and outside existing watercourses can be used to meet the lot area standards.
