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.
