Southlake Boulevard; at the southeast corner of Peytonville Road and W. Southlake Blvd. LEGAL DESCRIPTION: Lot 1 R, Block 1 R, Carroll High School Addition LAND USE CATEGORY: Public CURRENT ZONING: “S-P-1” Detailed Site Plan District HISTORY: Case ZA90-59, preliminary plat and Case ZA9060 final plat, approved November 20, 1990. Case ZA90-058, zoning change and site plan, for “S-P-1” zoning was approved December 4, 1990. This was the intial plan approval for new construction of the High School and support facilities. The plan approved the school building, football stadium and track, baseball field, tennis courts, practice fields, field house and parking areas. According to the City Council minutes, it was recognized that lighting was not shown on the site plan, but was specifically contemplated with regard to the tennis courts and baseball fields with the school receiving direction and agreeing to be “very careful not to disturb the neighborhood when installing lighting.” Case ZA97-108, revised site plan was approved October, 7, 1997. This plan added to the school building, the field house, the parking area and added a new softball field. Lighting of the football field was shown on the plan not to exceed 0.2 foot candles at the residential property lines. No lighting was shown for the tennis courts or baseball fields. Lighting Ordinance No. 693-B was approved September 7, 1999. Case ZA99-078, zoning change and site plan was approved June 20, 2000. This plan added the natatorium, accessory buildings, parking and changed the football stadium to a track and practice filed. A variance to allow lighting for the tennis courts was initially proposed, but was withdrawn. Case ZA00-006, plat revision was approved June 6, 2000. This plat added the land for the natatorium. LV04-001 Attachment A Page 1 STAFF COMMENTS: According to the applicants engineering, the lighting at the property line will be within the limits of the ordinance. The Lighting Ordinance does not speak to hours of operation, but that may be taken into consideration when considering a variance. The hours of operation for Bicentennial Park and Bob Jones Park’s baseball fields are as follows: Play is to stop at 10:00 PM and lights out by 10:30 PM Sunday through Thursday nights and one hour later on Friday and Saturday nights. The 20 footcandle standard in the lighting ordinance was arrived at after a survey of lighting levels on existing parking lots in the city. Athletic field lighting was not considered when the ordinance was written. All athletic fields lighted since the ordinance was adopted in 1999 have been permitted by the variance process in the ordinance. th The revised plans received Thursday February 27 reflect a change in the design criteria for the baseball field lighting. The new design is based on a 60/ 40 design criteria, that is a desired level of 60 footcandles on the infield and 40 footcandles on the outfield. Also, the applicant did not request a variance to the spill over limits at the property line. The applicants chart of spill levels shows a 1.04 average and 1.30 maximum illumination level for the vertical reading. The ordinance limits those levels to 0.5 footcandles. The new photometric plot shows average lumens outfield to be 41.9 and infield to be 70.9 initial footcandles. The maximums are 56.8 for outfield and 93.8 for infield.
