<br />CASE # 0 <br /> <br />CONSIDER PARKING RAMP LIGHTING <br />By: Steven Jankowski, Assistant City Engineer <br /> <br />Background: <br /> <br />Council has made inquiries as to the appropriate level dflightingin the municipal ramp; There <br />are several levels of ramp lighting. They include night time lighting, daytime lighting. and an <br />emergency lighting system which is supplied by a generator in the event of a power failure. The <br />building maintenance supervisor and the building official have been working together to insure <br />that these lighting levels meet building code.requirementsbut still operate economically. <br /> <br />Staff is currently working on the reduction of day time lighting levels. On bright sunny days light <br />levels have been measured within 1 foot- candle of the minimum lighting threshold in the darkest <br />locations within the ramp. Daytime lighting could be turned off in such instances. However to <br />address the issue of variable conditions (i.e. cloudy intervals or daytime storms) staff will be <br />installing photo sensors in the darker locations to activate the daytime lighting when they fall <br />below acceptable standards. These photo sensors cost less than $200 and will be installed by the <br />building maintenance department in mid July. The electrical savings will be evaluated by <br />comparing the post installation electric bill to a similar period from last year. <br /> <br />Staff will be measuring the current night time lighting . levels and comparing them with code <br />standards. Consideration will then be given to whether the City should pursue further <br />optimization of these lighting levels. While tuming the lighting system off completely during the <br />early moming hours may seem logical because of the unlikely use of the facility during this <br />period, this would be ill advised due to code requirements which must be met at all times the <br />public is available to the ramp. The ramp, because of its open design would be extremely <br />difficult to close on a daily basis. . <br /> <br />Action: <br /> <br />No action required. For jnformational pllrposes. <br /> <br />Reviewed By: <br />Director of Public Works/Principal City Engineer <br />City Engineer <br />Maintenance Supervisor <br />Building Official <br /> <br />PW: 07/21/09 <br /> <br />17 <br />
