are pulsar metal halides. At 24,000 hours, half will still be working and half will be out. Connexus does scheduled regroup lamping at 20,000 hours at dusk to dawn usage that is five years. Motion by Councilmember McGlone, seconded by Councilmember Elvig to recommend to City Council to stay with the 100 watt metal halide light fixtures that we already have. Motion carried. Voting Yes: Chairperson Backous and Councilmembers Elvig and McGlone. Voting No: None. Case 5.4 Consider Guard Rail Enhancements for the Parking Ramp Public Works Director/Principal City Engineer Olson reviewed the staff report and stated that there has been some concern with regard to the height of the guardrails, both on the top floor also in the second and third floors on the north side and the east side. Mr. Fossing of LSA Design was present to discuss the design features and the two options being presented and the related costs. Basically, Option A is currently right now the guardrail height at the roof level is 43 inches, the concrete portion of it is 2 foot 6 and the steel portion is 13 inches above that. It is basically doubling that existing rail. Option B would be fully enclosing levels 2 and 3 so there would be screen fencing that would go from the top of the wall to the other side of the lower wall. Mr. Fossing reviewed the costs for Option A is 147,658 and Option B is $302,000 and then Items 3 and 4 is separate from that. Item 3 is sunscreen and Option 4 is to fill in the sloping floors. Chairperson Backous stated they should decide between Option A and Option B first and then talk about 3 and 4. Motion by Councilmember Elvig, seconded by Councilmember McGlone to recommend to City Council to move forward with enhancements of thirteen inch where there are none on the fourth floor. Staff was directed to bring forward that alternative in a separate case on February 14th. Motion carried. Voting Yes: Chairperson Backous and Councilmembers Elvig and McGlone. There were two other alternatives that were discussed that evening. The first item that was discussed was a sunscreen. The sun hits, particularly in the winter months, the eyes of the driver driving from the 1st to the second floor or from the second to third floors and thereby blinds the driver. The recommendation of the Committee was to explore alternative methods to screen the sun similar to the banners that were installed next to the temporary construction access and not spend $43,325 to provide sun screens. The last action that was discussed was providing a chain link connection between the internal ramps. The cost of this alternative would result in a change order on the Contract for $15,911.
