• • D. Site and Neighborhood Planning Issues The site plan and operations plan for the proposed facility are inadequate to determine the impacts it will have on the surrounding area. At a minimum,the site and operations plan should include detail similar to that provided for the nearby Skaar Scattered Acres site, and should include: • • the location of all safety fencing, and gates; • any residential buildings within 2,000 feet of the site; • the location of any staging or scale areas, overburden storage or visual screening; • the location and type of erosion control measures; • information about any offsite users of quarried rock,with estimates of daily truck traffic; • location, length and surfacing of any driveways. and; • information about staging or phasing plans. This operation has the potential to generate impacts on neighboring residential properties in the form of noise, dust and blasting impacts, on surface water resources in the form of runoff and sedimentation, and on county roads in the form of increased truck traffic, dust and thud. E. Public,Local Government,And Agency Input Town Board Action On July 20, 1998,the Town Board of Cottage Grove voted to recommend approval of the CUP, with the condition that the area to be approved is limited to 15 acres. Minutes from the Town Board meeting indicate that Supervisor Anders will attend the county public hearing on 7/28. RPC Regional Planning Commission staff suggest that conditions and time frames similar to those imposed on the Skaar Scattered Acres site(CUP 1476) should apply to this petition as well. Land Conservation Department The county Land Conservation Department has expressed concerns about erosion control and stormwater management on the site. LCD points out that the soils in the area have a high silt and clay content, and in order to prevent sedimentation of Little Door Creek and its tributaries, recommends retention of all soil particles larger than 2 microns on site. Since this is a far more restrictive standard than the 5 micron particle retention standard used in the Lake Mendota Priority Watershed,achieving this result may be difficult using standard erosion control practices. III. CONCLUSIONS A. Summary of main issues/findings The project has the potential to impact nearby residences and surface water resources. Careful mitigation and control of quarrying operations will be necessary to minimize these impacts. B. Any recommended conditions of approval The ZNR Committee may wish to defer action on this request until issues can be resolved, revised plan materials submitted,and appropriate conditions developed. This project should be 4
