FOLLOW-UP ITEMS
Streetlight Replacement
The City streetlight replacement program began in earnest in 2015 and originally identified
13,000 lights for replacement. Approximately 1,500 lights remain. These remaining lights are the
post top variety which are mostly residential. Staff anticipates completing these replacements by
early 2027. The remaining replacements are estimated to cost roughly $1M.
The replacements are saving on wattage use and are being installed at a dim setting. The lights
and settings are tracked in ArcGIS which will allow for efficient auditing and data needs over
time
