The applicant's plan involves installing new stairs to gain lake access and <br /> installing new retaining walls to support the stairs. Stairs are permissible. With the walls.the <br /> applicant is hoping to be proactive in protecting the trees,vegetation, and shoreline on the <br /> property.The walls as proposed range from 1 to 6 feet in height. Because some of the walls will <br /> exceed 4' in height, engineered design is required. Site pictures are included in the packet to <br /> illustrate the existing drainage and slope issues on the site. <br /> Hardcover Variance (78-1700) <br /> This property is located in the Tier 1 of the Stormwater Overlay District which permits a <br /> maximum of 25% hardcover on the lot. The applicant is proposing 26.33% hardcover which is <br /> 171.25 square feet over the allowed amount. <br /> Lot Area and Width Variance (78-350) <br /> Zoning Code Section 78-72 provides options for the redevelopment of lots which do not meet <br /> the minimum area or width requirements for the respective zoning district.Substandard <br /> properties within the Shoreland Overlay District, like the subject lot, are able to be redeveloped <br /> without variances if specific standards are met;such as: <br /> 1. All setback requirements can be met. <br /> 2. A Type 1 sewage treatment system consistent with Minnesota Rules,chapter 7080, can <br /> be installed or the lot is connected to a public sewer; and <br /> 3. The impervious surface coverage meets all hardcover location and square footage <br />
