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 /> <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 /> <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 /> <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
