Meeting Date 9/02/2020
ITEM TITLE: RESOLUTION OF THE SAFETY COMMISSION OF THE CITY OF CHULA
VISTA APPROVING THE IMPLEMENTATION OF ALL-WAY STOP
CONTROL AT THE INTERSECTION OF SANTA VICTORIA ROAD AND
CALLE AVILA, AND TO ACCORDINGLY AMEND SCHEDULE II OF THE
REGISTER OF SCHEDULES MAINTAINED IN THE OFFICE OF THE
CITY ENGINEER
SUBMITTED BY: Principal Traffic Engineer
City Staff received a request from a resident for the installation of an all-way stop at the intersection of
Santa Victoria Road and Calle Avila (the “Intersection”) adjacent to Otay Ranch High School. Staff
conducted an investigation and prepared a warrant study that concluded that all-way stop control is
warranted.
RECOMMENDATION:
Safety Commission adopt the resolution.
DISCUSSION:
City Staff received a request from a resident requesting the installation of an all -way stop at the
Intersection, which is adjacent to Otay Ranch High School. Staff conducted an all-way stop warrant
study per Council Policy #478-03, the results of which are presented below.
When evaluating an intersection for all-way stop control, various factors are studied to determine the
need for implementation. The physical factors (topography) of an area, vehicle volumes and speeds,
roadway alignment (vertical and horizontal curves), collision history, pedestrian volumes and available
sight distance are all taken into consideration.
The Intersection has four legs: Santa Victoria Road is a northbound/southbound street with one lane of
travel in each direction. The Intersection provides access to Otay Ranch High School and the Villas de
Avila community. Santa Victoria Road is 38 feet wide, but at the curb extensions to define parking
areas, it is as narrow as 24 feet wide. There is parking on both sides of the street with a marked,
uncontrolled crosswalk across the north leg of Santa Victoria Road. The Intersection was observed to
be used heavily by Otay Ranch High School students in the morning and afternoon. The Average Daily
Traffic (ADT) on Santa Victoria Road is 4,537 with a 25 mph speed limit.
Calle Avila serves Otay Ranch High School and the Villas de Avila complex. East of Santa Victoria
Road, Calle Avila is a private street (east/west direction) with stop control at the Intersection. The ADT
approaching the Intersection 2,068.
In the past five years, the Intersection had one reported collision that may have been susceptible to
correction by the installation of an all-way stop control.

Meeting Date 9/02/2020
All-Way Stop Warrant Study:
Physical Conditions:
The following table shows the existing conditions for the streets at this intersection:
Street Santa Victoria Road Calle Avila
Width 38 feet at Intersection 28 feet
ADT (Year)
Approaching only 4,537 (2019) 657 (2019)

On-Street Parking Allowed Only in Condo Complex on
east side
Vertical Alignment 2.17% grade No information
Horizontal Alignment Tangent Tangent
An all-way stop warrant evaluation was conducted and the Intersection received a total of 55 points
based on the following conditions:
Criteria 1 - Accident History: (5 points assigned out of a maximum of 25 points)
▪ 5 points were assigned for 1 accident.
Criteria 2 - Unusual Conditions: (14 points assigned out of a maximum 21 points)
▪ 7 points assigned for being adjacent to high school
▪ 7 points assigned for being on a suggested route to school with no other stop control
Criteria 3 -Pedestrian Volume: (20 points assigned out of a maximum 20 points)
▪ 20 points were assigned because 96 pedestrians were observed crossing Santa Victoria Rd
between 2:10 pm to 3:10 pm on 8/8/2019.
Criteria 4 - Traffic Volume: (11 points assigned out of a maximum of 24 points)
▪ 11 points were assigned based on observed volumes.
Criteria 5 - Traffic Volume Difference: (5 points assigned out of a maximum 10 points)
▪ 5 points were assigned because of the Intersection’s volume ratio. Calle Avila approach
volumes were 50.6% of the approach volumes on Santa Victoria Road.
CONCLUSION:
The Intersection received a total of 55 points out of a possible 100 points, where a minimum of 45
Page 3, Item 1__
Meeting Date 9/02/2020
points are required to warrant the installation of an all-way stop control. Therefore, Staff recommends
implementing all-way stop control at the Intersection
FISCAL IMPACT:
The estimated cost for the installation of two stop signs, stop bars, crosswalk and pavement legends at
this intersection is $5,000. This cost will be funded by an existing Traffic Engineering Capital
Improvement Project.

SAFETY COMMISSION AGENDA STATEMENT
Item __ 2___
Meeting Date 9/02/2020
ITEM TITLE: RESOLUTION OF THE SAFETY COMMISSION OF THE CITY OF
CHULA VISTA RECOMMENDING THAT THE CHULA VISTA CITY
COUNCIL INCREASE THE EXISTING SPEED LIMIT ON
EASTLAKE PARKWAY BETWEEN OLYMPIC PARKWAY AND
HUNTE PARKWAY FROM 45 MPH TO 50 MPH, AND THAT
SCHEDULE X OF THE REGISTER MAINTAINED IN THE OFFICE
OF THE CITY ENGINEER BE AMENDED TO REFLECT THESE
SPEED LIMITS
SUBMITTED BY: Principal Traffic Engineer
Staff completed an Engineering and Traffic Survey (E&TS) on Eastlake Parkway between
Olympic Parkway and Hunte Parkway (the “Segment”) in accordance with the California
Vehicle Code (CVC) and California Manual on Uniform Traffic Control Devices (CAMUTCD),
which indicate that the posting of speed limits that are not the maximum or standard prima facie
speed limits defined by the CVC be determined by an E&TS for each street with a posted speed
limit within the City. Based on the results of the E&TS, staff has determined that the speed limit
on Eastlake Parkway between Olympic Parkway and Hunte Parkway be increased from 45 mph
to 50 mph (see Attachment 1, Location Plat).
RECOMMENDATION: That the Safety Commission adopt the resolution.
DISCUSSION:
The CVC establishes minimum and maximum prima facie speed limits for all streets in the State.
The minimum prima facie speed limit is 25 mph for specific roadway conditions and the
maximum speed limit is 65 mph (55 mph for undivided roads) and an Engineering and Traffic
Survey (E&TS) is required to change the prima facie speed limit from these preset limits for any
City roadway that do not meet those conditions.
The CVC requires that local agencies review changes in local speed limits every five to ten years
to determine if the existing street segment speed limits require updating due to the age of the
E&TS or changes in roadway and traffic conditions. In June 2019, staff completed an E&TS for
the segment of Eastlake Parkway between Olympic Parkway and Hunte Parkway in accordance
with the California Vehicle Code.
As described in the California Vehicle Code, the survey shall include:
(1) Prevailing speeds as determined by traffic engineering measurements;
(2) Accident records;
(3) Traffic/roadside conditions not readily apparent to the driver.
Currently, the existing posted speed limit on the Segment is 50 mph, and signs and pavement
legends have indicated 50 mph since prior to October 2012. However, Ordinance 3190 approved
Page 2, Item _ 2__
Meeting Date 9/02/2020
in July 2011 establishes a speed limit of 45 mph on the Segment, and its underlying E&TS has
expired. It is proposed to update the E&TS and Ordinance 3190 based on the observed 85th
percentile speed.
Physical Conditions
The following information describes the existing conditions along the subject Segment on
Eastlake Parkway:
• Six-lane Prime Arterial.
• Length/Width – 1.05 miles long and 104’ to 120’ wide.
• Average Daily Traffic: 12,718 (2018)
• Number of Lanes: 6 lanes (3 per direction).
• Existing Speed Limit – Posted 50 mph.
• 85% Percentile Speed: 1) Olympic PW to Birch Rd - 46 mph. 2) Birch Rd to Hunte PW –
50 mph.
• Striping – Six lanes of traffic.
• Parking – Parking is not allowed along entire segment.
• Bike Lanes in both directions.
• Horizontal Alignment – Horizontal Curve with a radius of 1100’ over a length of 204’
yields a design speed of 55 mph.
• Vertical Alignment – Crest Vertical Curve with a 7.25% over 1350’ yields a design speed
of 55 mph.
• Accident Rate History – The accident rate at this segment is 0.41 accidents per million
vehicle miles, which is lower than the rate of 1.36 for similar roadways in the State of
California (2016).
Traffic Calming
Given the short length and major roadway classification, no traffic calming measures are
feasible.

Speed Enforceability
If the proposed speed increase is not approved, the following are the only means of enforcing
speed on the Segment:
Page 3, Item _ 2__
Meeting Date 9/02/2020
• Basic Speed Law: police car matches speed of vehicle and determines that speed is
unsafe for current conditions. Infeasible due to insufficient police availability and the
segment is too short.
• Maximum Speed Law: use RADAR/LiDAR methods to enforce speed limit of 65 mph.
If the proposed speed limit is approved, police can use RADAR/LiDAR to enforce the approved
posted speed limit.
CONCLUSION:
When speed limits are appropriately established the following objectives are achieved:
- Meaningful, unambiguous enforcement
- Voluntary public compliance
- Clear identification of the unreasonable violator
- Elimination of unjustifiable “tolerances” of higher speed travel
Based on the 85th percentile speed of the roadway, as well as a low collision rate outlined in the
Engineering/Traffic Survey, staff has is recommending the speed limit increase.
Should the City Council establish the proposed 50 mph speed limit, Schedule X of the register
maintained in the Office of the City Engineer be amended to reflect the speed limit increase:
• Eastlake Parkway, between Olympic Parkway and Hunte Parkway, proposed Speed Limit
Increase to 50 mph.
FISCAL IMPACT:
There is no fiscal impact with the increase of the speed limit because existing signs and marking
already indicate the proposed speed limit.

RESOLUTION NO. SC-2020-_____
RESOLUTION OF THE SAFETY COMMISSION OF THE
CITY OF CHULA VISTA RECOMMENDING THAT THE
CHULA VISTA CITY COUNCIL INCREASE THE EXISTING
SPEED LIMIT ON EASTLAKE PARKWAY BETWEEN
OLYMPIC PARKWAY AND HUNTE PARKWAY FROM 45
MPH TO 50 MPH AND THAT SCHEDULE X OF THE
REGISTER MAINTAINED IN THE OFFICE OF THE CITY
ENGINEER BE AMENDED TO REFLECT THIS SPEED
LIMIT
WHEREAS, staff completed Engineering and Traffic Survey (E&TS) on Eastlake
Parkway between Olympic Parkway and Hunte Parkway (the “Segment”) in accordance with the
California Vehicle Code (CVC) and the California Manual on Uniform Traffic Control Devices
(CAMUTCD), which stipulate that posted speed limits be determined by an E&TS for each street
with a posted speed limit within the City except those determined by CVC-defined prima facie
limits; and
WHEREAS, as described in the CVC, the E&TS shall include: 1) Prevailing speeds as
determined by traffic engineering measurements; 2) Accident records; and 3) Traffic/roadside
conditions not apparent to the driver; and
WHEREAS, the CVC and CAMUTCD state that the speed limit shall be established at
the nearest 5 mph increment of the 85th percentile speed with a permitted 5 mph downward
adjustment allowed for and elevated accident rate; and
WHEREAS, the CVC indicates that an E&TS may be valid (and thus enforceable by the
Police Department) for a period of up to ten (10) years or a time when conditions of the roadway
change, whichever is sooner; and
WHEREAS, with a valid E&TS, the posted speed limit on a street can be enforced which
means that the Police Department can use RADAR/LIDAR technology to enforce the speed limit
and the burden of proving whether the driver was proceeding at a safe speed is on the driver; and
WHEREAS, the E&TS for the Segment is expired, and the Police Department can only
enforce speed on the Segment with respect to the Basic Speed Law, which would require that a
police officer to follow vehicles the officer deems to be traveling at unsafe speeds and that he/she
prove that the driver was proceeding at an unsafe speed; and
WHEREAS, the Segment is a major roadway with no feasible or effective measures to
implement traffic calming measures; and
WHEREAS, denial of this resolution perpetuates the expired status of the E&TS for the
Segment such that the Police Department will be unable to enforce the existing posted speed
limit using RADAR/LIDAR technology; and
Resolution No. SC 2020-____
Page 2
WHEREAS, the speed limit on the Segment is inaccurately posted at 50 mph although
the speed limit on the Segment by ordinance is currently 45 mph; and
WHEREAS, based on the 85th percentile speed of the roadway and the collision rate
referenced in the E&TS, staff has determined that speed limit be increased from 45 mph to 50
mph.
NOW, THEREFORE, BE IT RESOLVED that the Safety Commission of the City of
Chula Vista does hereby recommend that the City Council establish the proposed 50 mph speed
limit on Eastlake Parkway from Olympic Parkway to Hunte Parkway and that Schedule X of the
register maintained in the Office of the City Engineer be amended to reflect the proposed speed
limit as follows:
Eastlake Parkway, from Olympic Parkway to Hunte Parkway speed limit 50 mph.
