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

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 eachstreet with a postedspeedlimit 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 speedlimit 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) establishesminimum and maximum prima facie speedlimits for all streets in the State. The minimum prima facie speed limit is 25 miles per hour ( MPH) and the maximum speedlimit 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 speedsurvey for abovesegmentsin accordancewith 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 describesthe 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 RaisedMedian (2 per direction).

Existing SpeedLimit – Posted45 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 unreasonableviolator
Elimination of unjustifiable “ tolerances” of higher speed travel Based on the 85thpercentile 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 amendedto reflect the speedlimit decrease:

Olympic Parkway between Olympic Vista Road and Wueste Road, proposed Speed Limit decreaseto 40 mph.

FISCAL IMPACT:

The decreaseof the speedlimit would require the posting of new speedlimit signs and speedlimit pavement legends. This work will be funded by an existing Traffic Engineering Capital Improvement Project, TRF-0332, Signing and Striping Program.

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 accordancewith 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 speedlimit within the City; and
WHEREAS, as described in the CVC, the E& TS shall include: 1) Prevailing speedsas determined by traffic engineering measurements; 2) Accident records; and 3) Traffic/ roadside conditions not apparentto 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 speedlimit and be approved by a registeredCivil 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 meansthat 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 decreasedfrom 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 Docusign Envelope ID: F0847ADB- 3C85- 4B85- 87E3- 5B3E645DD556 esolution No. TSC 2024- 004
