Planning Commission Meeting Minutes August 10, 2023 Page 10 of 14 Planning Commission that streetlights do not need to comply with the proposed regulations. Krantz asked about the cost of the ballfield retrofit for lighting. Zuccaro says $250,000 and this includes lights and lighting systems. Baskett recalled the original options and wonders where the other cities fell in relation to our proposal. Brackett Hogstad says that other jurisdictions mostly employ use changes, or development type as their compliance trigger. Howe asked for clarity on the downtown exemption. Brackett Hogstad says the downtown area is subject to brightness and color regulations and has tighter restrictions on brightness but is exempt from trespass requirements. Brackett Hogstad mentions it is difficult to identify the offending light in an area like downtown. The lower lumen max is intended to help address the lack of trespass regulation. Baskett is more comfortable with the downtown exemption with more understanding. Public Comment: Cindy Bedell, resident, commented that the Option 2 changes are a step in the right direction, yet still thinks that there should be a requirement for existing homes. Residential light trespass should be included in her opinion. Some of the new homes south of Harper Lake have egregious lighting. Some modifications could be very simple, motion detectors next to homes only and not on backlots, no use of flood lights overnight. She thinks education will be important. She encourages the city to investigate providing discounts and samples at local hardware stores. Josh Cooperman, resident, is strong supporter of Dark Sky. He appreciates the work staff has put into this. Responding to other public comments, he thinks that security concerns are valid, but that has nothing to do with Dark Sky compliance. He thinks the Ordinance will have little impact due to overall sky glow from surrounding communities, but that it is still worthwhile. He thinks Louisville could set a positive example and that creative ideas could be used. He makes one more plug for correlated color temperature of the lighting. He mentions that Dark Sky International certifies lights up to 3,000 kelvins. Dark Sky International would prefer under 2,200, but it is difficult to find such lighting. He thinks 2,700 kelvins would be a good maximum, with a waiver option up to 3,000K, as a standard of 3,000K does not accomplish enough. Finally, regarding compliance, the original intention at City Council was to pursue amortization on a timeline of less than 10 years. That said, the Ordinance should reflect the community's desires. He still prefers amortization because it is more stringent, but he supports Option 2 as well. John Webb, resident, spoke on behalf of the Bee City Committee and the insects. He read a memo about the role night flyers play in pollination.
