Initial Assessment: Requests will be reviewed and screened to determine if the locations are eligible for the Traffic Calming Program. See map below for eligible and ineligible streets (PDF of eligible and ineligible streets) 

In order for a location to be eligible it must meet the following criteria and your street :

• The street must have a posted speed limit of 25 MPH or qualify as a residential street based on the criteria set in the California Vehicle Code. Arterials are prohibited from having speed humps installed.
• The street must have a minimum length of 500 feet between curves.
• The street can only be two vehicular travel lanes wide.
• City staff can determine that the benefits of the hump request does not pose a safety risk to roadway users or a reduction of emergency vehicle response times.
• The street must have a minimum score of 35 points from the project ranking recommendations (attached)

Petition Requests: Residents interested in traffic calming must submit a request to the City.  Signatures of a majority of neighborhood residences whose property line is immediately adjacent to the subject street must accompany the request to be considered. One vote per household is permitted. Use the form below to collect signatures.

Annually, staff will review, score and rank the requests.  Below is the criteria used for scoring and ranking.  Ranked projects are then brought to the BTSSC for a determination of what streets to proceed with as part of the annual traffic calming project. This will include an evaluation of available funding and if sufficient funding is not available for all of the eligible streets, then the locations that were not selected will be delayed until funding becomes available.

Timeline

Based on the evaluation from the BTSSC and staff, The City will survey both the residents and property owners to gauge support for the proposed solution with surveys being sent to both the street address and mailing address for the property. If a residence is owner occupied then the property owner would be eligible to submit two survey responses. In order for the hump installation to move forward, at least 50% of the surveys must be returned and over 50% of returned surveys must support installation of the humps. Once the survey is complete, a letter and/or e-mail will be sent to the residents/property owners informing them of the survey results.

If approved, the project will be included as part of the annual speed hump contract. If sufficient funding is not available for all of the approved hump locations then the locations with the lowest scores will be delayed until funding becomes available.
