Attachment 4 Mr. Paschke thought people would probably be past that area by the time they came up on that sign. He noted that the sign was before FedEx, so it's the furthest down point, past 280. Chair Pribyl asked if anyone from the audience would like to speak to please come forward. Ms. Alana Howey, 991 Parker Ave, indicated that light pollution was the primary concern with these. Roseville was already very light. It has a lot of lights, and the City does not get very dark in this area. These LEDs make it challenging to shade from lateral to above. There was increasing evidence that it can disrupt bird migration. It can impact human health significantly, too. A lot of this was emerging research, looking at a few things. One was the density of the signs in this small area within our community, with cumulative impacts of light. So, if you think about one sign, it would not necessarily be such a big deal. But now we have four signs in a small area. We do not know what those impacts are, so that concerns me. Ms. Howey explained that the International Dark Skies Organization has published some best practices for light recommendations. One of the things to think about was maybe thinking about shutting them off overnight so that birds aren't screwed up on their migratory path, shutting them off from 11 o'clock till an hour before sunrise, that sort of thing. Another aspect was that their recommendation for our type of community would be more in the 40 to 80 nits overnight versus the 500 listed here. From what she has read, the light restrictions are way excessive. She thought the lights were super bright when she went down the highway. She wondered how light they needed them to be. Those were her concerns, and she would like the Commission to consider them when making this decision. She thought they should start with one and not have it be carte blanche. Chair Pribyl thanked Ms. Howey for her concerns. Member Bjorum thought Clear Channel could clarify that, too, from Member McGahee’s original comment about how the illumination of the original billboards—they are obviously lit by floodlights—relates to the brightness of these new installations. Mr. Weiland explained that was an excellent question, but it was hard to measure because one reflected light off something you see with your eye versus something directed at your eye. We designed them to look similar in brightness so that you will not be able to tell the difference from your eye on how they operate. It was not necessarily apples or apples on how they operate. These are not operating any brighter; we want them in that same realm, and that's why there are the conditions, or why there are fewer nits at night or during the day, constantly changing for ambient conditions around it.
