Current Language 404.34(b)3

Any lighting installed for sports facilities or parking areas shall adhere to the following standards:

i. To minimize sports facilities lighting adverse off-site impacts, mounting heights shall be established to achieve a minimum lighting fixture angle of twenty-five degrees down from horizontal.

ii. Provide automatic and/or telephonic control system to enforce shut-off sports facilities lighting by 11:00 PM. On-site manual and/or telephonic control system shall also be provided to allow for the lights to be turned on or off at will (before curfew) to assure that only active and/or desired areas are lighted.

iii. Where applicable, the installed sports facility lighting shall not be used for parking area tasks. Parking areas shall be lighted by separate luminaires not associated with field illuminance needs. All such parking area lighting fixtures shall be fully shielded and installed such that no direct light is emitted above the horizontal plane. Total parking area lighting lumens shall be reduced by at least 30% or extinguished by 11:00 PM.
