To assure continued compliance with minimum retro-reflectivity requirements the city has adopted a "measured sign retroreflectivity" assessment method. This method consists of regular inspections with each sign being measured once in every twenty-four (24) month time period. These inspections are done in daylight with the retroreflectivity being measured using a hand-held, portable, contact reflectometer. This device provides a standardized methodology for measuring retroreflectivity pursuant to ASTM E1709. In the course of these inspections the city may employ department personnel or outside contractors to secure these measurements. Once out on the intended route the inspector gives each road sign a pass/fail mark on either a printed or electronic inventory for the particular route being inspected at that time. A repair work order is then generated from this inventory and all signs found to be sub-standard will be replaced in a timely manner.
