  7. Color Temperature Maximum 3,000K, except for sports fields/courts Source: northgatelighting.co.uk/wp-content/uploads/2017/08/color-temperature-scale.jpg | 7

  8. Exemptions – Single Family Dwellings Current: light fixtures with 2,000 lumens or less are exempt Proposed changes to exemption: ➢ Reduce lumens for exempt fixtures to 1,500 lumens (~ 75 watt bulb) ➢ Exempt only from the location/shielding and full cut-off requirements | 8

  9. Exemptions – Motion Activated Security Lighting Current exemptions: • Single family – if 6,000 lumens or less, extinguished within 5 min., and bulb not visible 5’ above property line • Other uses – if bulb not visible 5’ above property line Proposed changes to exemptions: ➢ Reduce lumens for single family to 4,000 lumens or less (~ 200 watt bulb) ➢ No change to 5 min. requirement for single family ➢ Replace 5’ above property line standard with a requirement for light to be directed onto the property | 9

  10. Sports Illumination Plans • Reduce the hours for lighting on outdoor playing fields/courts on residentially zoned and developed properties ➢ Current: 7:00 am to 11:00 pm ➢ Proposed: 7:00 am to 10:00 pm • Update the perimeter areas for playing fields/courts in coordination with FCPA • Require ARB review of stand-alone SIPs located in Historic Overlay Districts | 10

  11. Potential Future Amendments • Photometric plans are currently required for service station canopies and vehicles sales areas to demonstrate a maximum of 30 footcandles ➢ Consider expanding this requirement to other light intensive uses such as drive-throughs • Consider adding a requirement for lighting on private streets to comply with the same light source and light level requirements of the PFM for public streets • Consider overlay district light level standards similar to the model lighting ordinance of the International Dark Sky Association | 11
