The dome will be Type II-B construction and classified as an A-4 occupancy. It will have a maximum occupancy of 636. The Dome will not have a fire suppression system. The support building will have a fire suppression system. Refer to the code analysis for a complete presentation of code compliance. Entrance to the site will be from Ferrett Street. There will be 135 parking spaces. Overall, during the development of the dome and support building, 46.1% of the site will be impervious area, resulting in 53.9% as open/green space. An assumed additional 1.51 acres of impervious space will be generated during future phases which results in an ultimate impervious percentage of 63.7%, 36.3% pervious area. Stormwater will be collected via structures and pipes and directed to four infiltration basins. One on the west side of the site will be used for a portion of the dome which may be expanded or placed underground as future development occurs. Stormwater for the parking lot and the rest of the dome will be directed to the three western. The Preliminary Plat and Final Plat application are to combine the two lots into one. Additionally, an easement vacation request is included to vacate a portion of existing utility and drainage easements to allow for development on the site. The Final Plat shows that there will still be an easement on the entire perimeter of the site to adequately accommodate the existing and proposed utilities. VARIANCE REQUES The proposed athletic dome will be 78 -ft tall at the highest point. Because the height limit of the E-3 zone district is 65-ft, we are requesting a height variance. Please see the sheet AS-2 Elevations Variance Area to show the portion of the top of the dome that exceeds the height limitation and the proportional area in scale to the overall dome. Article II, Division 2, Section 117-53(b)(2)(a) in the City Code provides the review criteria for a variance request. Following are the review criteria with a statement on how this variance request addresses each criterion: A. In considering all requests for a variance and in taking subsequent action, the city staff, the board and the council shall make a finding of fact that the proposed action will not: 1. Impair an adequate supply of light and air to adjacent property. Response: There will be no impairment to the supply of light and air to the adjacent properties. The athletic dome complies with building setbacks and a 13-ft increase in height for the rounded portion of the dome top does not pose any encroachment issue of air or light to adjacent properties. Adjacent to the south is Highway 10. No shadowing will occur from the additional dome height to the south. To the west of the dome is a large portion of the subject site where there will be a future support clinic and restaurant building and therefore the dome does not encroach to any adjacent property to the west. To the north of the dome is the parking lot, and therefore the adjacent properties to the north are far enough away from the dome that they will not be impacted by the requested height increase. Directly to the east of the site is the local street, and the closest lot across the street is far enough to not be impacted either by the requested height increase. 2. Unreasonably increase the congestion in the public street. Response: The request for a height variance for the athletic facility will not impact traffic. While a height variance for most buildings is associated with an additional floor space and more people, the height for a Page 2 952.426.0699 + www.ISGInc.com
