Traffic Calming Review by Traffic Safety Concerns Committee and Transportation Safety Commission
Once the City has received the request form, the Transportation Safety Concerns Committee (City staff) and the TSC will conduct a preliminary assessment of the situation. This may include looking at past traffic counts and accident rates, assessing the probability of cut-through traffic on the road, and gathering information on vehicle speeds and volumes through the neighborhood.
The preliminary assessment will be pooled with other requests for traffic calming projects.
The projects will be ranked accordingly to the ranking criteria, and those of top priority will be selected as the following year’s traffic management projects. The number of projects selected each year will depend on funding availability. Those not selected will be notified, and applications will be kept for possible selection the following year.
Public Works staff, and TSC will hold meetings with residents of the affected neighborhood to develop strategies to combat the traffic problems residents are experiencing. This is an opportunity for residents to offer suggestions and for staff to educate the residents and explain the constraints under which the program works. Also, during these meetings,
performance targets to measure the success of the project will be established by consensus of the neighborhood. The “neighborhood” may include any residents or businesses whose access to the primary arterial may be affected by the project. The list of residents will be generated through the city’s Information & Technology Department.
Public Works staff will develop a draft management plan for each project, based on input from the neighborhood and on experience from previous traffic calming projects. The draft plan will undergo technical review, and additional changes may be made based on comments received. The plan will then be reviewed at a neighborhood meeting for consensus.
Public Works may decide to test all or part of an overall strategy recommended by the management plan. A test would be expected to last about sixty days. Notification of the tests will be sent to all residents and businesses in the area and the schedule will be posted to the test site. Tests involving road closures or access restrictions will be posted and sent to newspapers for publication. Results of the tests will be made available to the public.
Traffic Calming Final Decision by City Manager: The Transportation Safety Commission recommendation is reviewed for final decision or for request for further information/action to render a final decision by City Manager.
Traffic Calming Final Procedure: If no test is necessary or if no significant changes are required as a result of testing, Public Works will assemble a final implementation strategy. This will likely include engineering plans for any traffic calming devices, a signing and striping plan, a cost estimate for implementation, and a listing of the performance targets established by the neighborhood. These plans will be made available for review upon request. Construction and/or implementation will begin as soon as plans are complete and approved by the Public Works Director.
After a period of at least 60 days, Public Works will send a survey to residents to measure their satisfaction with the project, and conduct a traffic study to measure the changes in traffic behavior against targets established by the neighborhood. Results of both the survey and test data will be sent to residents. If performance targets are not met and the project is deemed ineffective at addressing the problem, Public Works may act to alter the design of the traffic calming devices or reconvene public meetings to discuss additional steps that may be needed.
Traffic calming strategies will remain in place for a period of at least 18 months, at which time Public Works staff will evaluate their effectiveness based on comments by residents, staff, and the community at large.
