Streetscape Lighting Improvements

Project Overview

The streetscape lighting along Ferry Street was expanded along the main downtown area.  Project entailed improvements to the walks, street and lighting.  Design for the project included site lighting design, light level analysis and HPS versus LED replacement analysis.  A study was conducted to determine the feasibility of using LED technology for the lamps versus traditional HID fixtures.  The study included review of projected energy savings, light levels, maintenance, and initial investment as well as the payback to use LED technology.  The LED lamps were not used due to a lengthy payback period.

This project was completed in conjunction with Prein & Newhof (Civil Engineering).
