City-Owned Street Lighting Study

Update of original article posted on January 27, 2019

We drove most of the streets of Ivins counting and photographing city-owned street and walkway lighting. This is the first step we need to take to determine how many of the city-owned existing lights meet the requirements of the International Dark Sky Association (IDA). Yes, we know there are other lights we need to analyze, but we have to start somewhere.

We counted 338 city-owned lights. Next, we need to determine if they meet IDAs shielding, lumens, and correlated color requirements (CCTs) for the City to get designated as an International Dark Sky Community.

Here’s a breakdown of what we found:

  • 1 box light
  • 1 of these
  • 34 lantern lights
  • 68 cobra lights
  • 187 bollard lights
  • 9 pole lights – doubles
  • 39 pole lights – singles

Here is where they are:

Here are the streets we covered (highlighted):

We conducted the lighting inventory on the streets highlighted. The other streets are primarily in subdivisions where there are typically no city-owned lights.
