The city installs traffic signals and signs in accordance with the Manual on Uniform Traffic Control Devices (MUTCD). This document, produced by the State of Iowa, sets the standards for signals and signs.
Occasionally, the city will be asked to evaluate a street or intersection to consider a change in the regulations. In this case, the City would conduct a traffic study to determine if a change is warranted under the specifications of the MUCTD. Please contact the Engineering Division at 515-278-3950 or via email to request a traffic study.
