ALL-WAY STOP SIGNS
The City Council of the City of Chula Vista does hereby resolve as
follows:
WHEREAS, at the August 14, 1990 meeting, during discussion of the
Oleander Avenue and East Oxford Street traffic problem, the City Council
indicated a need to modify the existing all-way stop policy to allow more
emphasis on school age pedestrian activity areas; and,
WHEREAS, Council also raised questions on the legal authority of
establishing all-way stops; and,
WHEREAS, local agencies, such as the City of Chula Vista, do have the
authority to adopt their own warrant system for the installation of all-way
stop controls since there is no mandated point or warrant system for the
placing of all-way stops; and,
WHEREAS, California Vehicle Code (CVC) 21354 leaves the weighing of
criteria to the discretion of local authorities and California Vehicle Code,
Section 21350 thru 21355, gives the authority to local agencies to install
all-way stop traffic controls upon streets in their respective jurisdiction;
and,
WHEREAS, staff has prepared a revision of the Ctty's all-way stop policy
that provides greater emphasis on pedestrian activity areas; and,
WHEREAS, at the Safety Commission meeting of November 8, 19gO, the Safety
Commission voted 7-0 to approve staff's report.
NOW, THEREFORE, BE IT RESOLVED that the City Council of the City of Chula

BACKGROUND
The CalTrans Traffic Manual and the Manual on Uniform Traffic Control
Devices list criteria in determining the need for an all-way stop.
Actual need for an all-way is determined by an engineering study which
examines the Special characteristics of the site.
All-way stop signs are very restrictive control s since they require all
motorists entering the intersection to stop at all times. When stop
signs are installed for speed control and/or there is no apparent traffic
reason for the stop (little or no cross traffic), motorists regard the
stop sign as an unnecessary impediment and often times do not make a
complete stop. When this occurs the expectations of other drivers and
pedestrians are altered, thereby Jeopardizing the safety performance of
the intersection. Although speeds will be lower in the vicinity of the
stop, speeds will be higher midblock as motorists try to makeup for the
time lost at the Unwarranted stop sign. Another negative aspect of
unwarranted stop signs is the increase in noise and pollution as vehicles
apply their brakes to slow down and accelerate out of the intersection.
It is impractical and impossible to install an all-way sto (or other
traffic control device such as a traffic signal) whenever and wherever a
request is made; otherwise during peak periods, extended delays to
motorists may result, thus forcing motorists to seek alternate routes
through parallels streets, often a residential area. A Traffic
Engineer's primary goal is to maintain safety and reduce vehicle delay.
PURPOSE
The purpose of a fully Justified, properly installed all-way stop is to
effectively assign right-of-way, maintain safety and reduce vehicle
delay. Generally, all-way stops are installed where traffic signals are
warranted and/or an accident history has been indicated by reported
accidents of a type susceptible to correction by an all-way stop.
POLXCY STATEMENT
It shall be the policy of the CIty of Chula Vista, through the Department
of Public Works/Engineering Division, to warrant the installation of
All-Way Stops in accordance with the following policy statements:

lhe California Vehicle Code, Section 2]350 thru 2]355, gives the
authority to local agencies to install a]]-way stop traffic controls
upon streets tn their respective jurisdiction.
According to Federal and State traffic control guidelines, all-way
stop installations should be reserved for the control of vehicular
traffic conflicts at intersections and should not be used as devices
to control speed.
The Ctty's policy for the installation of an all-way stop control
based on a point system. Points are assigned to traffic factors
based on the severity of traffic conditions. Factors measured are:
accident records
2. unusual conditions
3. pedestrian volumes
4. traffic volumes
5. traffic volume differentials

GENERAL:
A fully ;}ustifted, properly installed all-way stop can effectiveqy assign
right of way, reduce vehicle delay, and decrease accidents, Generally,
an all-way stop is reserved for the use at the intersection of two
through highways, and only as an interim traffic control measure prior to
stgna izat on. Stop signs are not to be used for speed control.
The posting of an intersection for all-way stop control should be based
on factual data. Warrants to be considered include:
1. Accident records
2. Unusual conditions
3. Traffic volumes
4. Traffic volume difference
5. Pedestrian volume
Points are assigned to each of these warrants. The total points possible
are 54. The installation of an all-way stop control is Justified with a
minimum of 30 points, unless any one of the CalTrans criteria is met.
ALL-WAY STOP POINT SYSTEM CRITERIA:
1. ACCIDENT WARRANT:
Two points are assigned for each accident susceptible to correction
by an all-way stop control during one full year prior to the
investigation date.

Nhere unusual conditions exist, such as a school, fire station,
playground, horizontal dr vertical curves, etc,, points are assigned
on the basis of engineering judgment. Unusual conditions shall be

considered only if within 50 feet o the subject intersection. In
residential neighborhoods where there is a concentration of school
age children activities separated from the resfdenttal neighborhood
by a collector street and coupled with other conditions, the City
Traffic Engineer may apply traffic engineering Judgment and waive
ltf
the ~u-polnt minimum point requirement to qua y the intersection
for an all-way stop control.
The 30-potnt minimum requirement may be waived and an all-way stop
ma~ be installed only if less restrictive controls have not
corrected a documented problem. '
All-way stops may be Justified based on projected volumes and
accident frequency when traffic signals are warranted and will be
Installed within a specified period of time.
