Further discussion included parking and street width based on City regulations and parking restrictions; advantage to the City of less asphalt installed due to the more narrow street width and smaller diameter cul-de-sac. Mr. Schwartz advised that the firs preliminary design had included a 100' cul-de-sac with island, and prompting staff s requested revision as indicated, based on the City's difficulty in maintaining those types of designs during the winter. Member DeBenedet advised that his only concern was how the developer intended to manage storm water. Vice Chair Stenlund noted that the goal was for a twenty (20) year service life and routine 48 hour rain event; and suggested pervious pavement for the cul-de-sac as a perfect opportunity for a grant from the area watershed district, since this is a limited traffic road. Mr. Schwartz noted that the soils were not great in this area. 8. LED Lighting Retrofit Plan Mr. Schwartz displayed a map of the areas outlined in Attachment A for a proposed LED Retrofit Four Year Plan from 2013 —2016. Mr. Schwartz advised that the City Council appropriated $25,000/year, beginning in 2013,to replace or retrofit existing lighting systems. Mr. Schwartz noted that these were for street lights owned by the City, with the remainder of those currently unaffected owned by Xcel Energy. As part of this plan, Mr. Schwartz advised that a light meter study was indicated for Larpenteur Avenue, felt to be over-lit at this time, and advised that anticipated spillover lighting from parking lots may allow elimination of some overhead lights. At the request of commissioners, Mr. Schwartz confirmed that it would require the hiring of a consultant or testing company for that study. Discussion included how the various areas were selected based on lighting age and how it fit the annual budget allotment; identification of the lights by I-35W as the oldest in the community, but the hardest to replace based on design issues, as well as original light installations on both sides of County Road B-2, with anticipated replacement only on the pedestrian side for safety issues; installation of lights on County Road C in about 2006; and ownership of lights by the City on the west side of Snelling Avenue, and the east side owned by Xcel. Member DeBenedet suggested that light replacements at the City Hall campus seemed to cut electrical power requirements by 2/3, but on County Road C, they were only reduced by a small fraction; and questioned why more significant reductions were not available as part of the replacement.
