Trucking and hauling shall be allowed between the hours of 6:00 a.m. and 7:00 p.m. Monday- Saturday. 16. Tiller will work with staff to combine all active Conditional Use Permits for each of the three sites in Elk River by the end of 2018. Background/Discussion Case No. CU 17-34 The applicant is seeking a Conditional Use Permit (CUP) amendment for mineral excavation on 12450 Ranch Road (PID 75-121-2000 etc.) and near the northern limits of Elk River, see location map attached. Site operations include stripping, extraction, processing, and recycling of concrete and asphalt reclamation. Materials suitable for reclamation will also be blended onsite with excavated aggregates. The applicant has previously received a CUP for this location. Portable Concrete Plant Portable concrete plants are used to produce materials for road construction, such as concrete pavement and bridge structures. The proposed plant will be located on site near the aggregate being sourced. The applicant has requested the concrete plant be portable and approved for the entirety of the site in order to keep the plant near the aggregate being sourced. Staff is recommending that the portable concrete plant maintain a 50 foot setback from all neighboring property lines. 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. Tiller has conducted sound level monitoring for all sites in Elk River and has demonstrated the ability to comply with the nighttime noise standards. This information has been received by the City of Elk River as part of their annual Mineral Excavation License application. Based on this information and monitoring of noise complaints from residents, staff recommends the approval of this request to permit a portable concrete plant on this site. Applicable Regulations The issuance of a Conditional Use Permit can be ordered only if the use at the proposed location: 1. Will not endanger, injure or detrimentally affect the use and enjoyment of other property in the immediate vicinity or the public health, safety, morals, comfort, convenience or general welfare of the neighborhood or the city. The proposed use will not detrimentally affect nearby property as the use fits with the intended use of the development and is located adjacent to other mineral excavation establishments. The annual permitting process takes neighboring properties into account. The proposed use will comply with MN Rules Chapter 7030, Noise Pollution Control for all sites during all operating hours.
