1 MINNETONKA PLANNING COMMISSION September 15, 2011 Brief Description Conditional use permits for pedestrian improvements in Minnetonka Mills Park Recommendation Recommend the city council approve the request Project No a Property Applicant Background Minnetonka Mills Park, north of Minnetonka Boulevard between I-494 and Plymouth Road. City of Minnetonka, represented by Perry Vetter In 2009, the city council approved a concept plan for development of Minnetonka Mills Park, which encompasses the property on both sides of Minnehaha Creek between I-494 and Plymouth Road. The plan contained a variety of components, including: botanical features, footpaths, pedestrian bridge crossings, creek overlooks, and tracings of the historic mills and other building foundations. (See pages A1 A2.) Since the concept plan approval, significant work has been done within the park: existing single-family homes owned by the city were demolished, invasive plant species were removed, and new plant species were planted. Construction of stone walls is on-going. Proposal Work is now set to begin on various pedestrian improvements included in the concept plan. However, some of the improvements would be within floodplain, wetland, and buffers areas surrounding Minnehaha Creek. (See pages A3 A4.) These improvements, and the construction activities required for each, may be regulated by one or more public agency: the Army Corps of Engineers, the Minnesota Department of Natural Resources (DNR), the Minnesota Board of Water and Soil Resources (BWSR), the Minnehaha Creek Watershed District (MCWD), and the city. A determination of which agency/agencies will regulate, review, and permit the proposed improvements can occur only after a meeting of representatives of these groups. City staff is working to facilitate such a meeting.

2 Meeting of September 15, 2011 Page 2 Subject: Minnetonka Mills Park In the meantime, the city is proposing to do all work which is clearly outside of the regulatory authority of these outside agencies. This work, which does not involve any floodplain fill or wetland impact, consists of: Earthen Trails. Earthen trails would be located throughout the site. These trails would be created simply through mowing and clearing of brush. In areas of uneven ground, the surface of the trail would be sculpted by hand. As pervious trails, no special city approval is required. Boardwalk. A boardwalk would be constructed on the south bank of the creek east of the Minnetonka Boulevard/Baker Road intersection. By city code, a boardwalk may be located with the shore impact zone of a creek only by conditional use permit. (City Code Subd.5) Formal Recreation Areas. Construction of more formal recreation areas including a formal seating area, to be known as the Heritage Garden, and various creekside patios and overlooks would occur throughout the park. By city code, public recreational uses are allowed within wetland buffers and within shore impact zone of a creek only by conditional use permit. (City Code Subd.7 and Subd.5) Approving Body The planning commission makes a recommendation to the city council, which has final authority to approve or deny the request. (City Code Subd.4) Staff Analysis Staff finds that the proposed work to be reasonable. (1) The proposed improvements would not adversely impact public health, safety, or welfare. Rather, they are intended to increase enjoyment of the community s natural and historic resources. (2) The proposed improvements would meet all minimum conditional use permit standards. These standards are outlined in the Supporting Information section of this report.

3 Meeting of September 15, 2011 Page 3 Subject: Minnetonka Mills Park Staff Recommendation (3) The proposed improvements are consistent with the previously approved concept plan for Minnetonka Mills Park. (4) Any work requiring floodplain fill or resulting in wetland impact would be reviewed at a later date. Recommend that the city council adopt the resolution on pages A12 A14. This resolution approves the following conditional use permits for pedestrian improvements at Minnetonka Mills Park: Conditional use permit for boardwalk within the shore impact zone; Conditional use permit for boardwalk within a wetland buffer; Conditional use permit for public recreational use within the shore impact zone; and Conditional use permit for public recreational use within a wetland buffer. Approval is based on the following findings: 1) The proposed improvements would not adversely impact public health, safety, or welfare. Rather, they are intended to increase enjoyment of the community s natural and historic resources. 2) The proposed improvements would meet all minimum conditional use permit standards. These standards are outlined in the Supporting Information section of this report. 3) The proposed improvements are consistent with the previously approved concept plan for Minnetonka Mills Park. Approval is subject to the following conditions: 1) No work may be done under these conditional use permits which requires floodplain fill or results in wetland impact. a. Boardwalk supports located within wetland buffers must each be less than two feet in diameter. b. Any grading work within floodplain areas must result in disturbance of less than 1,000 square feet or 20 cubic yards. 2) Existing wetland buffer areas must be maintained.

4 Meeting of September 15, 2011 Page 4 Subject: Minnetonka Mills Park 3) Prior to construction, install tree and wetland protection fencing and any other erosion control measures as required by natural resources staff. These items must be maintained throughout the course of construction. 4) Impervious materials, including crushed rock, may not be applied to earthen trails, without obtaining a floodplain alteration permit.

The proposed improvements would not adversely impact the creek. Rather, they are intended to increase enjoyment of this natural resource. b) the use is consistent with the goals, policies and objectives of the comprehensive plan; Finding: The proposed improvements are consistent with the comprehensive plan. The plan notes that parks in the Upper Minnehaha Creek corridor should be designed to implement complementary activities in appropriate areas that emphasis the creek corridor s natural resources, and recreational, educational, historic, and scenic values. c) the use does not have an undue adverse impact on governmental facilities, utilities, services or existing or proposed improvements; Finding: The proposed improvements would not adversely impact public facilities, utilities, or services. The funds associated with these improvements have been allocated in the Capital Improvements Plan (CIP).

Any conditions imposed upon such approvals shall be met. Finding: The pedestrian improvements proposed at this time do not require approval from any outside jurisdiction. Future Improvements As previously noted, some of the improvements approved with the Minnetonka Mills Park concept plan would be located within floodplain and wetland areas surrounding Minnehaha Creek. The conditional use and floodplain alteration permits required for these improvements will be brought to the planning commission and city council review following the determination of outside agency(s) will have jurisdictional authority. In addition, the trails throughout the park may require future review. Though currently planned as pervious, over time pervious trails may be covered with impervious materials, such as crushed rock, to: (1) prevent erosion; (2) reduce maintenance time and costs; and (3) establish the boundary of the trails. This impervious material would be considered fill, perhaps requiring conditional use and floodplain alteration permits.

8 Meeting of September 15, 2011 Page 8 Subject: Minnetonka Mills Park Natural Resources Neighborhood Comments Best management practices must be followed during the course of site preparation and construction activities. This would include installation and maintenance of a temporary rock driveway, erosion control, and tree protection fencing. As a condition of approval the applicant must submit a construction management plan detailing these management practices. The city sent notices to 51 area property owners and received the comments on pages A8 A10.

I have included a picture of where my house is located in relation to the park. I built this house in 1987 and have lived there since in peace, quiet and privacy. The plans as they sit are going to take that away and greatly devalue my house as I am SO close to the park. I would like to request that the city seriously consider purchasing my home. Please try to imagine how you would feel if this was your home. I would appreciate the opportunity to speak with you about this! Barb Seacord Home Cell A8
