Background /Discussion The applicant is seeking a Zone Change to Mineral Excavation Overlay and a Conditional Use Permit (CUP) for Mineral Excavation on approximately 63 acres along Baldwin Avenue and 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. Zo� The subject 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 district 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 225`h 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 MN State noise standards and will comply with the stricter night time standards during the period from 7:00 p.m. to 7:00 a.m. as defined by MN Rules Chapter 7030, Noise Pollution Control. Setbacks The setbacks as they apply to this project are 50 feet along Baldwin Ave and the first 540 feet from the southern property line from the southwest corner adjacent to PID #75- 103 -3100. Also, the setback of 30 feet is required along the property line adjacent to US Hwy 169 and the first 1,150 feet from the southern property line from the southeast corner adjacent to PID #75- 103 -4201. Because mining is occurring on properties to the north, it is suggested that mining permitted within the setback areas to avoid a windrow situation along the property lines in collaboration with mining operations to the north. Setback from the property line to the north 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.
