Installation & Removal Criteria

Speed Hump Location Considerations
  • The street shall provide access (via a driveway or on-street parking) to abutting residential and/or commercial properties (residential local or collector streets). Residential properties include multiple dwellings such as apartment complexes
  • The street shall not have more than one traffic lane in each direction.
  • The street shall have a regulatory speed limit of 25 mph or less.
  • The 85th percentile speed on the street section must be at least 7 mph over the regulatory speed limit.
  • Speed humps should not be located in a horizontal curve, on vertical curves where visibility of the hump is restricted, or on the approaches to these curves.
  • For speed hump installation, the street should have curb and gutter. Considerations may be given to streets without curb and gutter. In such cases, special care should be used to accommodate drainage and prevent vehicle run around.
  • Street segment boundaries identified for traffic calming should be uninterrupted segments of street (i.e., no stop signs).
If an applicant does identify a street segment with interrupted points, then the project plan may direct the existing interrupted points be removed.
  • Speed humps will not be located in front of a driveway or within an intersection. Speed humps shall be kept a minimum of 100 feet from the near curb line of an intersecting street.
  • Speed humps will not be located over manholes or adjacent to a fire hydrant.
  • Speed humps located near drainage inlets will be placed immediately downstream of the inlet.
  • Speed humps will be located as near as practical on property lines to minimize the intrusion of the speed hump on abutting property frontages.
  • To the extent possible, speed humps will be located near existing mid-block street lighting.
  • A speed hump will not be located in front of a property if the occupant objects to its placement or, in the case of multiple dwellings, if a majority of the households on the property object to its placement. Fulfillment of this requirement is the responsibility of the applicant (contact person).
  • The average daily traffic must be less than 5,000 vehicles per day to qualify for speed humps.
Speed Hump Spacing & Location
  • Speed humps will typically be placed 200 to 600 feet apart. Other spacing may be used upon based on engineering judgment.
  • On single short blocks (300 to 500 feet), a single speed hump will be positioned near the mid-point.
  • On single blocks of moderate length (500 to 1,000 feet), a two speed hump configuration at third points will be used.
  • On very long blocks (1,000 to 1,600 feet), three speed humps will be placed on approximate quarter points.
  • On lengthy continuous street segments or segments comprised of a number of blocks, desirable interior speed hump spacing will be 400 to 600 feet.
  • A street segment or block must be at least 300 feet to qualify for speed hump installation.
Speed Hump Removal
  • Citizens may request a street segment be reviewed for the possible removal of some or all of the existing humps. An application will be available from the Public Works Department.
The affected area will be determined by Public Works Department Engineering Division staff and will include primarily those properties facing or abutting the street segment on which speed humps are located. A property will be considered part of the affected area if its only ingress and egress route requires traveling over existing speed humps requested to be removed.
  • The removal request must originate from a resident, business, or entity whose property is within the affected segment area. The affected area will be determined by Public Works Engineering Division staff and will include primarily those properties facing or abutting the street segment on which speed humps are located. A property will be considered part of the affected area if its only ingress and egress route requires traveling over existing speed humps requested to be removed.
  • Notification / Evidence of Support
  • Subsequent to the application for speed hump removal on a segment, a map of the affected area will be prepared and a petition packet sent to the applicant (contact person) for documenting support for the removal. All properties within the affected area must be accounted for, either by signature and indication of preference (in favor or oppose) or by written statement by the contact person why a specific property was not represented. There must be at least a 67 percent evidence of support to further the process.

    Requests with either no petition or with a petition that does not account for all properties will be considered incomplete and will not further the process.

    The specific street segment indicated on the removal application will be the basis to identify the speed humps for removal. Final determination for the removal will be at the discretion of the City of Owasso Public Works Department staff.

    Based on engineering judgment, the review process may recommend removal of none, some, or all of the speed humps. Factors considered, but not limited to, are:
    • Existing speed hump locations and spacing
    • Stop / yield signs along the segment
    • Historical and existing traffic speed and volume information
    • Collision history
    • Presence or absence of sidewalks, schools and parks

If speed studies conducted along the requested segment or portions of the segment show the 85th percentile speed is greater than or equal to 7 mph over the posted speed limit, then no hump removal will occur along the segment or portion of the segment represented by the study.

In addition, the city reserves the right to remove any traffic calming measure that is potentially unsafe and impairs the public safety and welfare.

Design Standards, Construction, & Maintenance

The City of Owasso Public Works Department will prepare and maintain current design standards and installation and removal procedures for speed humps and other traffic calming devices in accordance with current design practices and criteria.

Design and construction or removal of traffic calming devices along with associated pavement markings and signs will be the responsibility of the Public Works Department. Future maintenance of traffic calming devices will be the responsibility of the City of Owasso.
