CC Work Session 2. 3. Meeting Date: 07/24/2012 Submitted For: Shane Nelson By: Len Linton, Engineering/Public Works Title: Street Light Installation Contract with Connexus Energy for Sunwood Drive Realignment Background: The realignment of Sunwood Drive will require 10 existing light fixtures to be relocated from their existing position to the new along the new alignment. In addition to the 10 relocated fixtures an additional 14 new fixtures are required. The cost to relocate the existing 10 fixtures and install 14 identical fixtures along with 33 electrical receptacles for boulevard trees and power to the center of the roundabout would be $103,932. These lights would be 100 Watt and 70 Watt Metal Halide fixtures identical to the 128 fixtures that would remain along the untouched portions of Sunwood Drive. The cost to relocate the existing 10 poles with LED components and install 14 LED fixtures along with 33 electrical receptacles for boulevard trees and power to the center of the roundabout would be $111,732. These lights would be 55 Watt fixtures and have a slightly different look than the 128 fixtures that would remain along the untouched portions of Sunwood Drive. Both metal halide and LED have similar "white" light. The cost to retrofit the remaining 128 street lights to have the LED fixture and would cost between $700 each for a total of $89,600. An analysis of the electrical cost savings versus the additional construction costs shows a significant payback period. The payback period to change to all LED is nearly 30 years. The payback period to install LED on all relocated and new street lights is nearly 13 years. Recommendation: Staff recommends installation of metal halide type fixtures identical to the one in place along existing Sunwood Drive. The cost has been budgeted for in the project and consistency of street lights is maintained for both aesthetics and maintenance issues. Funding Source: The project has $112,000 budgeted for street light replacement. Council Action: Motion to recommend entering into an agreement with Connexus Energy to relocate 10 existing metal halide fixtures and install 14 additional metal halide fixtures along with 33 duplex receptacles and power to the center of the roundabout in an amount of $103,932.
