Policy for the Consideration and Installation of Speed Humps
The City Council is granted the authority under State Statute to approve or deny all
traffic control requests based on conformance with the Minnesota Manual on Uniform
Traffic Control Devices (MnMUTCD) and local ordinances and regulations which may be
influenced by environmental, social, economic and/or financial implications within the city.
The City Council understands that because of the emotional situation often
associated with some requests, it is sometimes difficult to analyze such requests using
rational criteria. To enhance the City Council's ability to use rational criteria in evaluating
traffic control requests and minimize the installation of unnecessary signage and traffic
control devices throughout the city and provide for safer and more livable neighborhoods,
guidelines should be established.
Consideration of speed hump installation will only be given after the "problem"
situation has been addressed in accordance with the MnMUTCD and City policy/practice
including the Stop Sign Policy and traffic law enforcement. Speed hump systems may be
installed when the following guidelines are met:
1. The average traffic volume must be less than 1,500 vehicles and more than
200 vehicles in a 24 hour period (average daily traffic).
2. 50 percent of surveyed motorists must exceed 30 m.p.h. and/or 30 percent
must exceed 35 m.p.h., or 50 percent of the streets' traffic must be cut -
through traffic as determined by traffic counts and traffic forecasting
techniques.
3. The roadway must be less than or equal to 36 feet in width.
4. The road must have no more than two traffic lanes.
5. The street must have a speed limit of no more than 30 m.p.h.
6. The street must be a local access residential street, including minor
residential collector streets in a developed area.
7. The estimated diversion of local traffic to other adjacent local streets cannot
be greater than 20 percent of the existing average daily traffic.
8. Areas of streets for installation of speed humps must have a grade of 5
percent or less.
9. Speed humps will not be installed on streets within areas where horizontal
curves have less than a 300 foot centerline radius or in areas where a
minimum stopping sight distance is less than 200 feet.
10. Speed humps should be installed at intervals of approximately 250 feet to 500
feet, although this can vary depending on existing conditions.
11. Traffic signs, pavement markings and other guidelines not specified above for
speed hump design and installation shall be in accordance with the Institute
of Transportation Engineers document "Guidelines for the Design and
Application of Speed Humps" (1997).
PROCEDURES:
1. All speed hump requests will be reviewed by the City Engineer but requests
will only be considered and processed if supported by staff or by petition
signed by over 75% of the property owners whose property accesses the
street on which the speed humps are proposed.

2. If a valid petition is received, the City Engineer will evaluate the proposed location in
accordance with the above guidelines.
3. If a speed hump installation does appear feasible, a preliminary design for an installation
will be prepared by the City Engineer. This preliminary design will then be mailed to all
residents whose property abuts the proposed limits of the installation, as well as to other
property owners use this street on a daily basis as determined by the City Engineer.
4. A date will then be established for City Council consideration of the speed hump
installation request and all of the affected property owners as identified in point No. 3
will receive notice of the City Council meeting.
