ZC 17-02 and CU 17-02 The applicant is seeking a zone change to Mineral Excavation Overlay and a CUP for mineral excavation on approximately 61.3 acres along Baldwin Avenue near the northern limits of Elk River. Site operations will include stripping, extraction,processing, and recycling of concrete and asphalt reclamation. Materials suitable for reclamation will also be blended onsite with excavated aggregates. Zoning The property is currently zoned Commercial Reserve Transition (CRT) and the applicant is proposing to add the Mineral Excavation Overlay District to the site. The Mineral Excavation Overlay District designation allows for mining operations with approval of a CUP. Surrounding properties are used for mining and residential uses. Staff does not have any concerns with impacts to the surrounding area. Transportation/Access Access to the site will be via Baldwin Avenue,which borders the eastern side of the project area. This access point will be shared with the mining operation to the north. Most traffic will travel south along Baldwin and turn onto 225I Ave NW,which intersects Highway 169. All operation activities will meet road restriction rules. Hours of Operation The proposed hours of operation are 24 hours a day except for Sundays and holidays. The site will be subject to the State of Minnesota noise standards and will comply with the stricter night time standards during the period from 7 p.m. to 7 a.m. as defined by MN Rules Chapter 7030, Noise Pollution Control. Setbacks The setbacks to this project are 50 feet along Baldwin Ave. and the northern property line along Livonia Township. Also, the setback of 30 feet is required along the property line adjacent to US Hwy 169. Because mining is occurring on properties to the south,it is suggested that mining is permitted within the setback areas to avoid a windrow situation along the property lines in collaboration with mining operations to the south. Setback from the property line to the south will be 30 feet, unless mining collaboration agreement across property lines is confirmed. Environmental Review An Environmental review was completed for a gravel mine operation on November 7, 2016.
