Procedure for citizens requesting physical traffic calming measures in residential streets in Berkeley


Berkeley City Council passed a resolution in December 2009, establishing a process for evaluating citizens’ requests for physical traffic calming measures in residential streets. To start the process, citizens need to contact PW Transportation as a first step for requesting traffic calming by either phone or email:

The following procedure establishes the methodology for processing such requests:

  1. The PW Transportation Division evaluates citizens’ requests for physical traffic calming in residential streets on an annual basis, to coincide with the City of Berkeley’s bi-annual budget cycle.
  2. Requests need to be made in writing, detailing the nature, frequency and the impact of the traffic problem, using the City-provided form. The deadline for receiving requests is Dec 31 every year for processing in the following year. The PW Transportation Division as the owner of the process records and maintains a list of these requests. You must be a resident of the area/street to request a traffic calming study/any potential measures.
  3. Between Jan 1 and Feb 15 the staff, based on criteria set out in the Traffic Calming Policy, conducts an initial review of the request, and if the request warrants further investigation, the staff will define the impacted area and the petition area.
  4. The applicant(s) will then be given this information in order to complete signature collection, which should then be submitted by March 15.
  5. From Apr 15 to Jun15 traffic surveys are conducted to obtain pertinent traffic information. This data will be analyzed, and a determination will be made by July 15 whether the reported problem is validated.
  6. Following validation of the reported problem, the staff will spend the months of August and September to complete their study and identify possible solutions.
  7. During the months of October and November, the staff will meet with the affected community to seek their preferred solution out of the options presented by the staff. At the end of this process a consensus, as defined in the Traffic Calming Policy, is reached on the preferred solution.
  8. The staff will complete cost estimates for the selected solution(s) during the month of December, and will rank the project’s priority per the criteria set out in the City’s Traffic Calming Policy. The project will then be presented for inclusion in the Traffic Calming Capital Improvement Projects (CIP) list during the annual budget process.  Currently there is an annual budget of $50,000 citywide that will be applied to the top priority projects according to a point system (outlined in the Traffic Calming Policy) on an annual basis
