The City Council adopted Council Policy 000-14 which sets forth the criteria that are used to determine if road undulations will be recommended for installation. The criteria are very specific. Road undulations will only be installed on local streets. The through traffic volume on the street must exceed 500 vehicles per day.
In order to consider the installation of road undulations the 85th-percentile speed must be at or above 35 miles per hour. The 85th-percentile speed is the speed at which 85% of the vehicles are traveling at or below. Potential speed hump locations are reviewed with the Fire Department to determine if they will have negative effect on emergency response.
