ARDEN HILLS CITY COUNCIL WORK SESSION -SEPTEMBER 21,2009 2 IA. Green Lighting System for Hockey Rinks and Softball Fields (continued) Craig Gallup, Musko thanked the Council for their time and gave a formal presentation about athletic lighting, energy efficiency and Iife cycle costs. He noted that Musko was responsible for 80% of the outdoor athletic lighting in the State of Minnesota. Mr. Gallup indicated that not all outdoor lighting was created equally and that the cost of replacement, along with the utility expense should be taken into consideration. He noted that some lighting systems are even going wireless. Further explanation was given regarding the relation of spilled light in relation to the height of the light pole. Lastly he reviewed the pricing for various lighting systems and noted there were grants available for the systems. After his presentation, Mr. Gallup asked for comments or questions from the Council. Councilmember Holden questioned the warm-up period of the lights. Mr. Gallup explained that the ?fights took roughly five to six minutes to warm up and light at their peak level. Mayor Harpstead questioned if the existing poles could be used for the new lights and asked the age of the poles. Mr. Gallup stated he would work with the current light poles and that this would be a cost savings to the City. Park and Recreation Manager Olson stated that she was unsure but thought that the poles were at least 15 years old. Mayor Harpstead asked if there were complaints about light spilling over from the hockey rinks for ball fields. Park and Recreation Manager Olson explained there have been calls from concerned citizens if the lights are left on beyond the allotted times. Mayor Harpstead felt this lighting system was a step in the right direction both economically and environmentally. He thanked Mr. Gallop for his presentation. It was the consensus of the Council to direct staff to pursue the new green lighting system grant opportunities.
