Speed Humps

Description
Speed humps are asphalt mounds placed on roadways for the purpose of slowing traffic. Speed humps are different than speed bumps, which are commonly seen in parking lots or on private streets.

Speed humps are typically:
  • on residential streets
  • not used on major roads or bus routes
  • placed mid-block, not at an intersection
  • not on grades greater than 8%
  • work well with curb extensions
Disadvantages
  • Residents living near speed humps must tolerate increased noise levels as vehicles traverse speed humps day and night.
  • Vehicles may drive on sidewalks or through front yards to avoid speed humps.
  • Traffic may be diverted to previously quiet parallel streets in the neighborhood.
  • Emergency service response time suffers.
  • Motorized street sweeping equipment cannot be used at speed hump locations.
  • Speed humps interfere with street repaving, decreasing the effectiveness of both the speed hump and the new pavement surface.
  • Speed humps block the flow of drainage water on some streets and can cause flooding problems.
  • Speed humps require signing and striping, which some residents consider unattractive.
Speed Hump Process
  1. Once residents express interest in speed humps, city staff sends speed information to residents.
  2. Residents complete and return a Warrant for Speed Hump Form along with the Speed Hump Petition with signatures of residents who live on the street where speed hump is proposed.
  3. city staff conducts a preliminary inspection of the street to determine if speed hump is appropriate. If not, staff notifies residents in writing that their street is not eligible for a speed hump.
  4. If residents wish to pursue speed hump, they notify city staff. Residents and staff work together to determine appropriate locations for speed hump, and staff prepares petition showing the proposed location.
  5. Residents circulate petition and document 100% support from affected area neighborhood residences.
  6. Residents submit signed petition back to the city. city staff verifies the petition.
  7. If consensus building is adequate, staff has the hump installed as shown on the petition. After installation, staff will sign and stripe the hump according to city standards.
  8. Residents may circulate petition and obtain signatures for up to 6 months from the distribution of the petitions. Any petitions older than 6 months that are submitted to the city will be rejected.
  9. If, at a future time, residents want to remove speed hump, they must submit a petition with at least 51% approval of the original affected neighborhood area. If approved, residents must pay to remove the hump
