TRAFFIC SAFETY COMMISSION STAFF REPORT
Item 5.1
Meeting Date 12/12/24
ITEM TITLE: RESOLUTION OF THE TRAFFIC SAFETY COMMISSION OF THE
CITY OF CHULA VISTA APPROVING AN ALL-WAY STOP AT THE
INTERSECTION OF SANTA CHRISTINA AVENUE AND SANTA
LIZA AVENUE, AND TO ACCORDINGLY AMEND SCHEDULE II OF
THE REGISTER OF SCHEDULES MAINTAINED IN THE OFFICE OF
THE CITY ENGINEER
SUBMITTED BY: City Traffic Engineer
At the request of a member of the community, Staff evaluated Santa Christina Avenue and Santa
Liza Avenue (“Intersection”) for all-way stop control. The warrant study determined that the
Intersection accumulated 46 points. Staff is recommending the implementation of an all-way stop
control at the Intersection.
RECOMMENDATION
That the Traffic Safety Commission approve the resolution.
DISCUSSION
Existing Conditions
The Intersection is located in Otay Ranch Village 2. Both Santa Christina Avenue and Santa Liza
Avenue are classified as minor roads. The Intersection is located in the vicinity of Sonia
Sotomayor Elementary School, which is the primary generator of pedestrian and vehicular traffic
during the peak hours.
All-Way Stop Warrant Study
Traffic Engineering staff studied the Intersection in accordance with the California Manual on
Uniform Traffic Control Devices (CA MUTCD) and City Council Policy No. 478-03, which sets
criteria for determining whether all-way stop control is warranted at an intersection based on its
location, collision history, unusual conditions, pedestrian and traffic volumes, and how traffic
volumes between the major and minor approach streets relate (Attachment 2).
In addition, there are three unique situations that suggest all-way stop control could be warranted
irrespective of the total accumulated points, paraphrased below:
Case 1: CA MUTCD criteria are met
Case 2: One of the warrant criteria accumulated the maximum points available to that criterion
Case 3: If the Intersection: is in a residence district as defined by the California Vehicle Code, is
not within 600 feet of another controlled intersection, and there is a parallel arterial road that can
act as an alternative route; the Intersection can accumulate ten additional points.

Page 2, Item 5.1
Meeting Date 12/12/24
The table below summarizes the points accumulated for each warrant criterion:
Warrant Criteria Maximum Accumulated
Case 1 Caltrans Criteria
Case 2 Max Points on a
Criterion
Case 3 Residence District 10 0
1 Accidents in 12 Months 25 0
2 Unusual Conditions 21 19
3 Pedestrian Volume 20 20
4 Traffic Volume 24 0
5 Traffic Volume Difference 10 7
Total 45 (Minimum to
warrant) 46
CONCLUSION
As shown on the above table, the intersection accumulated a total of 46 points. Therefore, Staff
recommends the implementation of an all-way stop control at the Intersection.
FISCAL IMPACT
The addition of two stop signs, limit lines, crosswalk lines, and “STOP” pavement legends would
require nominal cost of approximately $2,500. This work is anticipated to be performed by City
forces, funded by capital improvement project TRF0332 “Signing and Striping Program.”

TRAFFIC SAFETY COMMISSION AGENDA STATEMENT
Item __5.2____
Meeting Date 12/12/24
ITEM TITLE: RESOLUTION OF THE SAFETY COMMISSION OF THE CITY OF
CHULA VISTA RECOMMENDING THAT THE CHULA VISTA CITY
COUNCIL REDUCE THE EXISTING SPEED LIMIT ON OLYMPIC
PARKWAY BETWEEN HUNTE PARKWAY AND OLYMPIC VISTA
ROAD FROM 50 MPH TO 45 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: City Traffic Engineer
Staff completed an Engineering and Traffic Survey for a segment of Olympic Parkway in
accordance with the California Vehicle Code, which indicates that the posting of speed limits be
determined by an Engineering and Traffic Survey for each street with a posted speed limit within
the City (with some exceptions). Based on the results of the speed survey, staff has determined
that the speed limit on Olympic Parkway between Hunte Parkway and Olympic Vista Road be
reduced from 50 mph to 45 mph (see Attachment “A”, Location Plat).
RECOMMENDATION: That the Traffic Safety Commission concur with staff and recommend
that the Chula Vista City Council reduce the existing speed limit on Olympic Parkway between
Hunte Parkway and Olympic Vista Road from 50 mph to 45 mph, and that Schedule X of the
register maintained in the Office of the City Engineer be amended to reflect these speed limits
DISCUSSION:
The California Vehicle Code (CVC) establishes minimum and maximum prima facie speed limits
for all streets in the State. The minimum prima facie speed limit is 25 miles per hour (MPH) and
the maximum speed limit is 65 MPH and an engineering and traffic survey (E&TS) is required to
change the prima facie and/or update various speed limits in the City.
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
engineering and traffic survey or due to changes in roadway and traffic conditions.
Currently, the existing posted speed limit on Olympic Parkway between Hunte Parkway and
Olympic Vista Road is 50 mph.
City staff completed a speed survey for above segments 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.

Page 2, Item _5.2__
Meeting Date 12/12/24
Physical Conditions
The following information describes the existing conditions along of Olympic Parkway:
Classification Between Olympic Parkway between Hunte Parkway and Olympic Vista
Road – Four Lane Major Arterial.
Length/Width – 2,428 feet (0.46 miles) long and 88’ to 92’ wide.
Average Daily Traffic: 12,241
Number of Lanes: Four lanes with Raised Median (2 per direction).
Existing Speed Limit – Posted 50 mph.
85% Percentile Speed: 48 mph.
Striping – Four lanes of traffic with a raised median.
Parking – Parking is not allowed along both side of this segment.
Bike Lanes in both directions.
Horizontal Alignment – Horizontal Curve east of Hunte Parkway.
Accident Rate History – The accident rate at this segment is 0.32 (WB)/0.33 (EB) accidents
per million vehicle miles, which is lower than the rate of 1.00 for similar roadways in the
State of California (2021).
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 the collision rate outlined in the
Engineering/Traffic Survey, staff has determined that the speed limit on Olympic Parkway
between Hunte Parkway and Olympic Vista Road be reduced from 50 mph to 45 mph.
Should the City Council establish the proposed 45 mph speed limit, Schedule X of the register
maintained in the Office of the City Engineer be amended to reflect the speed limit decrease:
Olympic Parkway between Hunte Parkway and Olympic Vista Road, proposed Speed
Limit decrease to 45 mph.
FISCAL IMPACT:
The decrease of the speed limit would require the posting of new speed limit signs and speed limit
pavement legends. This work will be funded by an existing Traffic Engineering Capital
Improvement Project, TRF-0332, Signing and Striping Program.

Date of Speed Survey: 8/20/2024
Critical Speed (85th) 48 MPH
50th Percentile 43 MPH
Existing Posted Speed Limit 50 MPH
10 MPH Pace 38-47 MPH
Percent in Pace 77%
Street Classification: Minor Arterial (Divided)
Length of Street Segment: 0.46 miles
Average Daily Traffic: 6,016
Total Accidents (3 years): 1

Accident Rate (MVM): 0.33
California Statewide Accidents Rate (MVM, 2019-2021): 1.00
Justification: When the nearest 5 mph increment of the 85th-percentile speed would require a
rounding up, the speed limit may be rounded down to the nearest 5 mph increment
below the 85th percentile speed, if no further reduction is used (CVC 22358.6(c); CA-
MUTCD Section 2B.13, standard 12a, Option 2).
TRAFFIC ENGINEER’S RECOMMENDATIONS/AUTHORITY:
Posted Speed Limit: 45 MPH
This survey was prepared in accordance with the requirements of Section 627 of the California Vehicle
Code using methods prescribed in Section 2B.13 of the California Manual on Uniform Traffic Control
Devices. Based on the measured critical speeds, it is appropriate and justified to recommend the posted
speed limit be 45 MPH along the subject segment of the road.
APPROVALS:
☐ Recertification of the existing speed zone per Sections 22357,
22358, and 40802 of the California Vehicle Code
☒ Establishment of new speed zone

RESOLUTION OF THE TRAFFIC SAFETY COMMISSION
OF THE CITY OF CHULA VISTA RECOMMENDING THAT
THE CHULA VISTA CITY COUNCIL DECREASE THE
EXISTING SPEED LIMIT ON OLYMPIC PARKWAY
BETWEEN HUNTE PARKWAY TO OLYMPIC VISTA ROAD
FROM 50 MPH TO 45 MPH, AND THAT SCHEDULE X OF
THE REGISTER MAINTAINED IN THE OFFICE OF THE
CITY ENGINEER BE AMENDED TO REFLECT THE
REVISED SPEED LIMIT
WHEREAS, staff completed an Engineering and Traffic Survey (E&TS) on a segment of
Olympic Parkway from Hunte Parkway to Olympic Vista Road in accordance with the California
Vehicle Code (CVC), which stipulates that posted speed limits be determined by an Engineering
and Traffic Survey for each street with a posted speed limit within the City; and
WHEREAS, as described in the CVC, the E&TS shall include: 1) Prevailing speeds as
determined by traffic engineering measurements; 2) Collision records; and 3) Traffic/roadside
conditions not apparent to the driver; and
WHEREAS, the California Manual on Uniform Traffic Control Devices (CA MUTCD)
states that the speed limit shall be established at the nearest 5 mph increment of the 85th
percentile speed. Also, if the 5-mph reduction is applied, the E&TS shall document in writing
the conditions and justification for the lower speed limit and be approved by a registered Civil or
Traffic Engineer; 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 fourteen (14) 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 street can be enforced “prima
facie,” 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, denial of this resolution perpetuates the expired status of the E&TS for
Olympic Parkway such that the Police Department will be unable to enforce the posted speed
limit using RADAR/LIDAR technology; 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 on Olympic Parkway between
Hunte Parkway and Olympic Vista Road should be decreased from 50 mph to 45 mph; and
NOW, THEREFORE, BE IT RESOLVED that the Traffic Safety Commission of the City
of Chula Vista does hereby recommend that the City Council, establish the proposed 45 mph
speed limit and that Schedule X of the register maintained in the Office of the City Engineer be
amended to reflect the speed limit increase as follows:

TRAFFIC SAFETY COMMISSION AGENDA STATEMENT
Item __5.3____
Meeting Date 12/12/24
ITEM TITLE: RESOLUTION OF THE SAFETY COMMISSION OF THE CITY OF
CHULA VISTA RECOMMENDING THAT THE CHULA VISTA CITY
COUNCIL REDUCE THE EXISTING SPEED LIMIT ON OLYMPIC
PARKWAY BETWEEN OLYMPIC VISTA ROAD AND WUESTE
ROAD FROM 45 MPH TO 40 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: City Traffic Engineer
Staff completed an Engineering and Traffic Survey for a segment of Olympic Parkway in
accordance with the California Vehicle Code, which indicates that the posting of speed limits be
determined by an Engineering and Traffic Survey for each street with a posted speed limit within
the City (with some exceptions). Based on the results of the speed survey, staff has determined
that the speed limit on Olympic Parkway between Olympic Vista Road and Wueste Road be
reduced from 45 mph to 40 mph (see Attachment “A”, Location Plat).
RECOMMENDATION: That the Traffic Safety Commission concur with staff and recommend
that the Chula Vista City Council reduce the existing speed limit on Olympic Parkway between
Olympic Vista Road and Wueste Road be reduced from 45 mph to 40 mph, and that Schedule X
of the register maintained in the Office of the City Engineer be amended to reflect these speed
limits
DISCUSSION:
The California Vehicle Code (CVC) establishes minimum and maximum prima facie speed limits
for all streets in the State. The minimum prima facie speed limit is 25 miles per hour (MPH) and
the maximum speed limit is 65 MPH and an engineering and traffic survey (E&TS) is required to
change the prima facie and/or update various speed limits in the City.
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
engineering and traffic survey or due to changes in roadway and traffic conditions.
Currently, the existing posted speed limit on Olympic Parkway between Olympic Vista Road and
Wueste Road is 45 mph.
City staff completed a speed survey for above segments 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.

Meeting Date 12/12/24
Physical Conditions
The following information describes the existing conditions along of Olympic Parkway
Classification Between Olympic Parkway between Olympic Vista Road and Wueste Road
– Four Lane Major Arterial.
Length/Width – 2,833 feet (0.53 miles) long and 66’ to 88’ wide.
Average Daily Traffic: 5,902
Number of Lanes: Four lanes with Raised Median (2 per direction).
Existing Speed Limit – Posted 45 mph.
85% Percentile Speed: 41 mph (WB)/42 mph (EB).
Striping – Four lanes of traffic with a raised median.
Parking – Parking is not allowed along both side of this segment.
Bike Lanes in both directions.
Horizontal Alignment – Horizontal Curve east of Olympic Vista Road.
Accident Rate History – The accident rate at this segment is 1.53 (WB)/1.42 (EB) accidents
per million vehicle miles, which is lower than the rate of 1.00 for similar roadways in the
State of California (2021).
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 the collision rate outlined in the
Engineering/Traffic Survey, staff has determined that the speed limit on Olympic Parkway
between Olympic Vista Road and Wueste Road be reduced from 45 mph to 40 mph.
Should the City Council establish the proposed 40 mph speed limit, Schedule X of the register
maintained in the Office of the City Engineer be amended to reflect the speed limit decrease:
Olympic Parkway between Olympic Vista Road and Wueste Road, proposed Speed Limit
decrease to 40 mph.
FISCAL IMPACT:
The decrease of the speed limit would require the posting of new speed limit signs and speed limit
pavement legends. This work will be funded by an existing Traffic Engineering Capital
Improvement Project, TRF-0332, Signing and Striping Program.

RESOLUTION NO. TSC-2024-______
RESOLUTION OF THE TRAFFIC SAFETY COMMISSION
OF THE CITY OF CHULA VISTA RECOMMENDING THAT
THE CHULA VISTA CITY COUNCIL DECREASE THE
EXISTING SPEED LIMIT ON OLYMPIC PARKWAY
BETWEEN OLYMPIC VISTA ROAD TO WUESTE ROAD
FROM 45 MPH TO 40 MPH, AND THAT SCHEDULE X OF
THE REGISTER MAINTAINED IN THE OFFICE OF THE
CITY ENGINEER BE AMENDED TO REFLECT THE
REVISED SPEED LIMIT
WHEREAS, staff completed an Engineering and Traffic Survey (E&TS) on a segment of
Olympic Parkway in accordance with the California Vehicle Code (CVC), which stipulates that
posted speed limits be determined by an Engineering and Traffic Survey for each street with a
posted speed limit within the City; 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 California Manual on Uniform Traffic Control Devices (CA MUTCD)
states that the speed limit shall be established at the nearest 5 mph increment of the 85th
percentile speed. Also, if the 5-mph reduction is applied, the E&TS shall document in writing
the conditions and justification for the lower speed limit and be approved by a registered Civil or
Traffic Engineer; 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 fourteen (14) 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 street can be enforced “prima
facie,” 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, denial of this resolution perpetuates the expired status of the E&TS for
Olympic Parkway such that the Police Department will be unable to enforce the posted speed
limit using RADAR/LIDAR technology; 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 on Olympic Parkway between
Olympic Vista Road and Wueste Road should be decreased from 45 mph to 40 mph; and
NOW, THEREFORE, BE IT RESOLVED that the Traffic Safety Commission of the City
of Chula Vista does hereby recommend that the City Council, establish the proposed 40 mph

speed limit and that Schedule X of the register maintained in the Office of the City Engineer be

proposed speed limit decrease to 40 mph.
