The City of Chanhassen does not install speed humps (bumps) on our public streets for the following reasons:

• Speed humps cause delays for police and fire vehicles of 3-10 seconds per hump.
• Maintenance activities, including snow plowing, are significantly more difficult to accomplish.  In addition, they become a danger to the traveling public and maintenance staff when hidden by snow.
• Negative impacts of increased braking and acceleration.
• Speeds may increase between humps as drivers try to make up for lost time.
• Noise levels may increase.
• Negative impact on air quality and energy consumption.
• Speeds may increase over time as drivers get used to the feel of the speed humps.
• Traffic volume may be diverted to adjacent streets as drivers seek alternate routes to avoid the speed humps.
• Some motorists may drive with their wheels in the gutter, bike lane, or road shoulder in order to minimize the impact of the humps.
