City of Arden Hills, Minnesota <br />Sign Retroreflectivity Policy <br />Article I. Purpose and Goal <br />The purpose of this policy is to establish how the City will implement an assessment or <br />management method, or combination of methods, to meet the minimum sign retroreflectivity <br />requirements in the Minnesota Manual on Uniform Traffic Control Devices (MN MUTCD). <br />Substantial conformance with the MN MUTCD is achieved by having a method in place to <br />maintain minimum retroreflectivity levels. Conformance does not require or guarantee that <br />every individual sign in the city will meet or exceed the minimum retroreflective levels at every <br />point in time. <br />The goal of this policy is to improve public safety on the City's streets and roads and prioritize <br />the City's limited resources to replace signs. <br />Article II. Applicable Signs <br />This policy applies to all regulatory, warning, and guide signs as set forth in the MN MUTCD. <br />Pursuant to Section 2A.8 of the MN MUTCD the City excludes the following signs from the <br />retroreflectivity maintenance guidelines: <br />A. Parking, Standing, and Stopping signs (R7 and R8 series) <br />B. Walking, Hitchhiking, Crossing signs (R9 series, R10-1 through R10-4b) <br />C. Acknowledgement signs, including Memorial signs <br />D. All signs with blue or brown backgrounds <br />E. Bikeway signs that are intended for exclusive use by bicyclists or pedestrians <br />Article III.
