The presentation ofthe City of Louisville Citywide Signal Warrant Analysis, and Via Appia Corridor Analysis included the following: The history of the Via Appia Corridor Analysis of Spring 2004; and the Summary of Signal Warrant Analysis of Fall 2004. The six intersections studied were Via Appia and Pine; Via Appia and Tyler; Via Appia and Lafayette; Dillon and Pierce; McCaslin and Washington; and South Boulder Road and Eisenhower. All traffic counts were conducted on September 14, 2004. Speed data was collected concurrently and accident data was reviewed. The intersections of PineNia Appia and Pierce/Dillon would meet warrants for traffic signals. W oolfall reviewed the traffic calming devices along Via Appia, such as reducing the number of lanes, more speed reminder signs, raised pedestrian crossing or intersections, diverting traffic to Tyler, which would require new signage and street striping. He noted the cost would approach one million dollars. He explained the roundabouts concepts in place of traffic signals at Via Appia and Tyler. He outlined the choices for the intersections would be a traffic signal at Pine, traffic signal at Tyler, roundabout at Pine, or at Tyler. Mayor Sisk opened the public hearing and requested public comment. PUBLIC COMMENT Alex Amiello, 4090 26th Street, Boulder, CO offered a PowerPoint presentation, which centered on roundabouts. He explained a roundabout design, and pointed out the differences between traffic circles, rotaries and roundabouts. He reviewed the history of roundabouts, and noted there are approximately 100 roundabouts in the United States. He had several examples of roundabouts throughout the State of Colorado. He outlined the cost of the roundabout located on the Rock Creek Parkway in Superior, Colorado. He noted the advantages of roundabouts include slower vehicle speeds in intersections; safety, reduced delay, lower maintenance cost, and improved operation during off-peak. He stated roundabouts are safer intersections and reduce conflicts. He explained the disadvantages of roundabouts are right-of way issues; costs; construction impacts, and public opinion. Chip Weincek, 672 W. Pine Street, Louisville, CO thanked the Mayor and Council for the thorough traffic study performed on Via Appia. He voiced his opinion that roundabouts would be a good solution for Via Appia, and noted success of the new roundabout in the Town of Superior. He presented a petition signed by citizens requesting consideration of an alternative to a traffic light at W. Pine and Via Appia. Gerry Christensen, 778 Owl Court, Louisville, CO requested that the speed limit along Via Appia not be increased.
