The property's±118 feet of depth is challenging, particularly due to <br /> fact that the 75-foot and average lake setbacks; and the 30-foot rear yard setback nearly <br /> overlap. The required setbacks result in a 5 foot deep building envelope. <br /> The proposed 0.1 foot setback poses additional challenges regarding construction,the building <br /> code,fire codes, as well as the logistics of working within the adjacent property owned by the <br /> Hennepin County Regional Rail Authority(HCRRA). Included within Exhibit G are comments from <br /> the City's Engineer, Building Official, and the rear neighbor HCRAA. Resident neighbor <br /> comments are also attached as Exhibit H. <br /> Hardcover Variances (Sections 78-1700) <br /> The existing hardcover level is 42.9%;the addition is proposed to be constructed over an <br /> existing patio. No new hardcover is proposed. Due to the change in the nature of the <br /> nonconforming hardcover,an expansion from non-building to building, a hardcover variance is <br /> required. <br /> Governing Regulation:Variance(Section 78-123) <br /> In reviewing applications for variance, the Planning Commission shall consider the effect of the <br /> proposed variance upon the health, safety and welfare of the community, existing and <br />
