If citizens are interested in having speed humps installed on their street, the following process applies:

1. Citizen Request - Citizens should contact CDOT to request speed humps.

2. Evaluation - CDOT evaluates the street to determine if speed humps will address the citizens' traffic concerns and if the street meets the required criteria for speed hump installation.

3. Criteria:

• A street must be classified as a two-lane, local residential street.  
• Average Weekday Traffic (AAWT) volumes should be greater than 1,000.
• The speed of 15% of the vehicles should be equal to or greater than five (5) miles over the posted speed limit.
• Grade is less than or equal to 8%.
• Horizontal radius of street is less than or equal to 300.

• Street's current speed limit should be posted as 25 mph if it is a local street, or 30 mph if it is a neighborhood collector.
• Street should not be a primary emergency response route.

4. Neighborhood Support - If a street qualifies for speed humps, neighborhood support is desired, and can be obtained by one of two methods: 

1)  A letter of endorsement from the neighborhood association based upon a board vote.  The neighborhood association will be required to notify affected property owners (as defined by CDOT) of the impending installation, and no petition will be required, or

2)  If the neighborhood association does not support the proposed service, the resident can petition.  A petition requires signatures from at least  60% of all property owners in the impact area.  If a petition is required, the CDOT will define the impact area and issue the petition.

5. Prioritization for Installation - After the request is submitted to CDOT, the street will be evaluated and rated for priority. Petitions are mailed to citizens of the highest ranking 35-40 streets in winter / spring. Installation is accomplished by annual contract in late spring or summer.

* Due to the large number of requests, neighborhoods may have to wait before receiving speed humps. Neighborhoods that do not rate high on the City's priority list, and therefore do not make the following year's installation schedule, may elect to pay for the total cost of the speed humps. By doing this, they will be included on the next installation schedule. The neighborhoods will not be reimbursed by the City at a later date.
