Public Works Committee 5. 5. Meeting Date: 03/31/2015 By: Bruce Westby, Engineering/Public Works Title: Consider Street and Pedestrian Facility Lighting Plans - Center Street and Riverdale Drive Purpose/Background: Purpose: The purpose of this case is to consider proposed street and pedestrian facility lighting plans for Center Street and Riverdale Drive. Background: Staff has been working with Connexus Energy to develop street and pedestrian facility lighting plans for both the Center Street and Riverdale Drive projects. Street and pedestrian facility lighting was not included in the construction plans as bid for either project, but staff believes street and pedestrian facility lighting is appropriate for both projects and is seeking input from the Public Works committee on the currently proposed designs attached to this case. Riverdale Drive Lighting Plans Connexus Energy has provided the City with a proposal including costs for 27 street lights with 135 watt LED shoebox style light fixtures mounted on 30-foot tall fiberglass poles, as well as 27 pedestrian facility lights with Traditionaire style 50 watt LED light fixtures on 14-foot tall fiberglass poles with 14 of these lights located along the 10-foot wide Mississippi River Trail that will be constructed along the south side of Riverdale Drive this spring, and the other 13 lights along the 10-foot wide City trail on the north side of Riverdale. This design would provide continuous lighting along the entire corridor that is being reconstructed and extended as part of the Riverdale Drive project that will be completed this spring. A cost estimate for the street and pedestrian facility lights is attached. Conduits for lighting were installed under each of the driveways and street intersections with the Riverdale Drive project so none of the existing infrastructure will be damaged. Center Street Lighting Plans Connexus Energy has provided the City with 3 proposals to date. The first lighting proposal was submitted on October 3, 2014 and included 2 street lights at the intersection of Center Street and 145th Avenue NW with 135 watt LED shoebox style light fixtures mounted on 25-foot tall poles that match the pole and fixture styles along Sunwood Drive, and ten (10) 50 watt LED lights on 14-foot tall poles. Attached is a dated drawing showing this design. The estimated cost for this design was $39,206. The second lighting proposal was submitted on February 24, 2015 and included 2 street lights at the intersection of Center Street and 145th Avenue NW with 135 watt LED shoebox style light fixtures mounted on 25-foot tall poles that match the pole and fixture styles along Sunwood Drive, and eight (8) 50 watt LED lights on 14-foot tall poles. Attached is a dated drawing showing this design. City staff requested the revised design because the lighting levels between Sunwood Drive and 140 Avenue on the first proposal appeared to be excessive so two were removed. The estimated cost for this design was $34,583. The third lighting proposal was submitted on March 13, 2015 and included 2 street lights at the intersection of
