Case File:CU 12-21 Spectrum sports complex Page 3 baseball field. Spectrum has indicated their plans to move the bleachers around, to accommodate seasonal activities. The area will need to be graded to maintain the necessary"flat" surface for sports fields. Much of the property is located within the flood fringe, and the applicant must prove there is no increase to the flood elevations. Staff and the DNR have reviewed the application documents, and are comfortable with the proposal. A formal NPDES permit will need to be approved because the impacted are is larger than 1 acre. Parking Parking for assembly,including sports arenas,is based on one parking stall per 3 seats at design capacity. The plans include six 42-seat movable bleachers,generating 252 seats,requiring 84 parking stalls. Because there are a number of activities proposed for the athletic complex, staff applied the parking demand of the single highest user,which is likely to be football. In addition to the 73 parking spaces, Spectrum provides 110 proof of parking/ overflow spaces, exceeding the requirement. In summary, the facility provides 73 of the required 84 spaces,plus an additional 110 spacing in the overflow area. Lighting The site improvements include additional parking lot lighting, and in phase II, field lighting. Lighting levels have been provided for both the parking lot and the field. Parking lot lighting The parking lot lights meet the lighting requirements of the ordinance, although it is unclear how high the poles are. Field lighting Phase II of the project is the lighting of the main athletic field. There is no timetable to add the lights. Four 70 foot high poles are proposed,with hooded fixtures. The lighting plan shows light directed at the field;at the adjacent property lines (measured three feet above ground level), the foot-candles measure no higher than .04. At this level, the nearest home site, according to the Kliever Lake Fields East plat,is 150 feet away. The nearest home is 460 feet to the east, and 490 feet to the south. Field lighting is not regulated specifically by the Zoning Ordinance. In these situations, the Planning Commission should look to the standards for granting a Conditional Use Permit, determining if these standards are satisfied. Generally, the largest issue associated with field lighting is impact to adjacent property owners. Staff comments have been centered on the reach of the lighting on adjacent county roads and residential property. While the lights are designed to minimize light spill (confirmed by the light photometric plan), a neighbor will still see illumination in the night sky. While this illumination cannot be blocked, the landscaping plan was designed to create a vegetative buffer on the south property line, to help mitigate the impacts. Landscaping The ordinance requires landscaping at a ratio of 3 trees,plus one tree per 40 feet of perimeter of the `described area'. Spectrum has developed a landscaping plan that is based the number of trees on the perimeter of the lot south of Trott Brook,which is supported by staff. The landscaping plan does not include the area north of Trott Brook in calculating tree requirements, as no activity is proposed here; N:\Departments\Community Development\Planning\Case Files\CUP\CU 12-21 Spectrum Field Complex\CU 12-21 SR to PC 11-13-12.docx
