CITY OF DUBLIN Memo
OffIce of the City Manager
To: Members of Dublin City Council
From: Community Services Advisory Commission
Subject: Traffic Calming Policy
Date: September 15, 1999
Attached please find Resolution 42-99 adopting a traffic calming policy for the City of Dublin. This
resolution and the associated policy were prepared by the Community Services Advisory Commission
(CSAC) for Council's review and approval.
In June of this year, City Council requested that the Community Services Advisory Commission
develop a process through which residents could request traffic calming measures within a
neighborhood. Since given this assignment, the Commission has held five meetings dedicated
specifically to this task. Input was given by the City Engineer and Chief of Police and a presentation
was made to the Commission by the City of Columbus Traffic Calming Coordinator. Additionally,
the Commission reviewed several traffic calming policies from other communities throughout the
country including policies from Portland, Oregon; Fairfax, Virginia; Greenbelt, Maryland; Dallas,
Texas; Broken Arrow, Arizona; and Columbus Ohio. The Commission also reviewed two draft
policies previously prepared for Council by Traffic Engineering Services, Inc. and the Transportation
Task Force. From these policies and staff input, the attached traffic calming policy was developed.
The policy is designed to allow for resident input and participation throughout the process, This
includes residents initiating neighborhood safety and awareness programs before the City considers
traffic calming alternatives, as well as involving residents in petition circulation and traffic calming
devise selection. CSAC determined that active resident participation will lead to more meaningful
results. Further, CSAC designed this policy as an additional tool for the City to remedy traffic issues
in residential areas. It is an extraordinary measure attempting to balance all facets of safety and
community standards when other available remedies have not adequately addressed residential traffic
calming concems.
Two issues not included in the policy, but discussed at length by the Commission, involved cost
sharing by residents and future street design. Members were of a consensus view that while some
policies from other communities did contain cost sharing as a program component, this would not be
recommended for the City of Dublin's program. Three factors that differentiated the City of Dublin
from those cities with cost sharing programs were the high service levels offered in Dublin, the
relative size of our community and potential disparate taxpayer effect. The Commission also
discussed the importance of focusing on the design of streets within new residential developments,
to better enhance traffic safety and minimize street modifications in the future.
Thank you for your consideration of this policy. Should you have any questions or comments related
to the policy, please contact Rick Gerber, CSAC Chair or Michelle Crandall, Management Assistant.

City of Dublin
Traffic Calming Policy
I. Definitions
Affected Area - The area in which the placement of traffic calming devices will
affect. This shall be determined by defining the area significantly affected by
street modifications and with input from residents. At a minimum this will
include the households located on the affected street and any households located
on cul-de-sacs attached to the affected street.
Cul-de-sac - A short street having only one end open to traffic and the other end
being permanently terminated with a vehicular turn around provided.
Cut-through Traffic - Traffic which uses local or collector streets to travel
through a residential neighborhood without having an origin or destination within
the neighborhood.
Loop Street - A street that has both of its terminuses on the same street.
II, Process
This policy is designed to provide a process through which residents can request
traffic calming measures within neighborhoods. Each step explained below has
been summarized in the attached flowchart.
A. City Receives Request
A request for the study and design of traffic calming measures may be
initiated by any resident ofthe City of Dublin.
B. Neighborhood Involvement Assessed
After a request has been received, the City will evaluate to what extent
other activities have been pursued by the residents of the requesting area.
If efforts, such as requests for increased enforcement and neighborhood
speed watch programs have been initiated by the residents and have not
been determined effective in the reduction of speed, volume and cut-
through traffic, then the request will proceed to the next step. If such
efforts have not been pursued, the City will advise the requesting applicant
as to programs they would need to initiate prior to proceeding with a
traffic calming request.
C. Pre-qualification of Street
Traffic calming measures are suitable in residential areas to manage speed,
volume and cut-through traffic. Therefore, characteristics of the streets
must be residential in nature. The street pre-qualifications are designed to
insure that the street segment is appropriate for considering traffic
calming. Since there are negative impacts of traffic calming devices,
some restrictions, in the best interest of emergency and transit services,
have been added to the list of pre-qualifications.
Streets must meet the following standards in order to pre-qualify for traffic
calming:
1. The street has a posted speed limit of 25 mph or less.
2. The street is classified as a local or collector on the City's
thoroughfare plan.
3. The street has a right-of-way that is 60 feet wide or less.
4. The street has a standard curb and gutter cross section, and/or all
drainage and safety concerns can be addressed to the satisfaction of
the City Engineer.
5. The street is at least 1000 feet in length.
6. The street is not a cul-de-sac street.
7. The street is not a loop street within a subdivision.
8. The street is not along a COT A bus route.
9. The street is not a street that has a fire station or so close to a fire
station that it is a primary emergency route.
If the street meets all of the above pre-qualification standards, the request
proceeds to the next step. If the street does not meet all of these standards,
then the request for traffic calming is not considered further.
D. Affected Area Defined
Once a street has met the pre-qualification standards, the affected area will
then be defined. Such determination will be completed by the City
Manager or the City Manager's designee, with input from residents.
E. Petition Requested
Following a determination of the affected area, a petition is requested from
the households of the affected area. This petition is to be circulated by the
resident(s) requesting traffic calming measures.
F. Petition Received by the City
Once received, the petition will be reviewed and validated by the City. In
order for the request to proceed, the petition must contain signatures from
two-thirds of the households in the affected area and 90% of the
households on the affected street.
G. Comprehensive Study Completed
Once streets are pre-qualified, and the appropriate percentages of
signatures are received and validated, the City will perform a
comprehensive study of the affected area. The study will be performed by
a qualified professional engmeer who has expenence m traffic
engmeenng. The study will include collecting speed and volume data
along the routes and studying the affect of the traffic calming devices on
City services. The study will also examine existing traffic control devices
along the street. If any existing device is found to be unwarranted, it is
subject to removal regardless of whether the street receives treatment for
traffic calming.
H. Street Priority
Through a point system, the data gathered in the comprehensive study will
then be used to establish a street priority ranking. The point system will
be according to the following criteria:
1. Speed
a. 5 points for each 1 mph the 85th percentile speed exceeds
32mph.
b. Minus 5 points for each 1 mph the 85th percentile speed is
less than 32mph.
c. If the 85th percentile speeds are less than 28mph, the street
shall not be considered for traffic calming.
2. Volume
a. Local Streets
1. 1 point for each 100 vehicles above 1000 vehicles
per day.
2. Minus 1 point for each 100 vehicles below 1000
vehicles per day.
b. Collector Streets
1. 1 point for each 100 vehicles above 2000 vehicles
per day.
2. Minus 1 point for each 100 vehicles below 2000
vehicles per day.
3. Cut-through Traffic
'l2 point for each 1 % the percentage of cut-through traffic exceeds
20%.
The points will be totaled in a chart similar to the one below. The streets
that qualify will be ranked in order from the most points to the least points
in a table similar to the one found below.
Cut-through Total

I. Traffic Calming Measures Selected
Working with the residents in the affected area, City Staff will select an
appropriate type of traffic calming measure(s) for the street. Stop signs
and traffic lights are not considered traffic calming measures for the
purpose of this policy. Concurrence of two-thirds of the households in the
affected area and 90% of the households on the affected street will be
required to agree upon the type of traffic calming measure(s) to be
implemented.
J. Funding and Installation
Following the selection of traffic calming measures, the street will be
placed on a priority list for funding and installation. Based on the level of
funding allocated for this purpose, streets shall be funded beginning with
the highest ranked street. If all streets contained on the list cannot be
funded during a year, the list will be carried over to the next year.
