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

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 speedlimit 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 speedlimit 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 streetsin the State. The minimum prima facie speedlimit 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 changethe prima facie and/or updatevarious speedlimits in the City.

The CVC requires that local agenciesreview changesin local speedlimits 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 changesin 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 describedin the California Vehicle Code, the survey shall include:
1) Prevailing speedsasdetermined by traffic engineering measurements; 2) Accident records;
3) Traffic/ roadsideconditions not readily apparentto the driver.

Meeting Date 12/12/24
Physical Conditions
The following information describesthe 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 RaisedMedian (2 per direction).

Existing SpeedLimit – Posted50 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 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 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 amendedto reflect the speedlimit decrease:

Olympic Parkway between Hunte Parkway and Olympic Vista Road, proposed Speed Limit decreaseto 45 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 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 segmentof Olympic Parkway from Hunte Parkway to Olympic Vista Road in accordance with the California Vehicle Code (CVC), which stipulates that posted speedlimits 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 speedlimit on street can be enforced “prima facie,” which means that the Police Department can use RADAR/ LIDAR technology to enforce the speedlimit and the burden of proving whether the driver was proceeding at a safe speedis 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 amendedto reflect the speedlimit increaseasfollows:
