AGENDA ITEM Item No.: 13 Date: August 12, 2019 Item Description: LAI 9-000051 — Dale Gustafson o/b/o John & Trudy Wilgers, 1905 Concordia St, Variance — Resolution Presenter: Melanie Curtis Agenda Consent Agenda Planner Section: 1. Purpose. This application is regarding variance approvals relating to repair of a lakeshore slope failure. 2. MN§15.99 Application Deadline. The application was received on June 19, 2019 and considered to be complete on July 3rd. Therefore the 60 -Day review period expires on September 1, 2019. 3. Background/ Summary. While the foundation work for the new home was underway, there were several consecutive rain events resulting in failure of the lower portion of the lake slope on the property. The applicant is proposing to install a subterranean timber wall grid system in the area of the recent slope failure. The grid layout will create "boxes" to be filled with soil to recreate the slope. Deep rooted plants are proposed to be installed on the slope. Because the walls are not permitted within the lake yard, a 75 -foot lake setback variance is required. This is the second slope failure in the last 7 years. 4. Planning Commission Vote and Comment. On July 15th the Planning Commission held a public hearing. Following the public hearing the Planning Commission voted 6 to 0 in favor of a motion to approve the requested setback variance for the walls. 5. Public Comment. No written comments from the neighbors were received; one neighbor spoke at the public hearing. Please refer to the draft minutes (Exhibit C) for more detail. 6. Staff Recommendation. The City's engineer provided the following comments. Staff recommends approval conditioned upon the applicant providing the requested information. These conditions have been included in the draft approval resolution. a. Wall and site plans specific to this site should be submitted for review and approval. The plans should include existing and proposed contours, location of subterranean wall (including draintile with pipe material, diameter, and invert elevations indicated), erosion control, and proposed restoration/landscaping. b. It appears that the slope repair needs to extend into the adjacent property to the north. The design should include all areas needing stabilization, and a temporary easement/permanent agreement may be necessary with the adjacent property owner. COUNCIL ACTION REQUESTED Motion to adopt or amend the approval resolution. Prepared By: V11GG Reviewed By: J. Barnhart Approved By: -Sb)X
