SUMMARY
Based on the provisions of California Vehicle Code (CVC) Section 22357 and 22358 and
pursuant to authority under Chula Vista Municipal Code (CVMC) Section 10.48.020, the City
Engineer has determined that a 45 mph speed limit be established on La Media Road between
Olympic Parkway and Birch Road/State Street.
ENVIRONMENTAL REVIEW
The Director of Development Services has reviewed the proposed activities for complialzce with
the California Environmental Quality Act (CEQA) and has determined that the activities qualify
for a Class 1 (c) categorical exemption pursuant to Section 15301 [Existing Facilities] of the
State CEQA Guidelines because the proposal involves negligible or no expansion of an existing
City street use. Thus, no further environmental review is necessary.
RECOMMENDATION
Council adopt the Ordinance.
BOARDS/COMMISSION RECOMMENDATION
At the September 7, 2011 meeting of the Safety Commission, a motion was. made to accept
staff's recommendation and approve the establishment of the 45 mph posted speed limit on La
Media Road between Olympic Parkway and Birch Road/State Street. The motion carried by a
vote of 6 (in favor) - 0 (opposed) - 1 {absent).

DISCUSSION
Currently, there are 45 mph posted speed limit signs and legends on La Media Road between
Olympic Parkway and Birch Road/State Street. However, the posted speed limit was not
established by an "Engineering and Traffic Survey" and without the adoption of City Council
Ordinance as required by the California Vehicle Code and the Chula Vista Municipal Code.
Speed zones are established on the basis of an engineering study. The engineering study
includes an analysis of the current speed distribution of free-flowing vehicles along La Media
Road without an impact of any roadside or nearby development and /or construction. Now that
construction activity within this roadway has been completed and accepted by the City, the speed
limit can be established.
City staff completed a speed survey along La Media Road between Olympic Parkway and Birch
Road/State Street in accordance with the California Vehicle Code Section 22357, 22358, 40802
and the Chula Vista Municipal Code Section 10.48.020, which indicates that the posting of speed
limits be determined by an Engineering and Traffic Survey at least once every seven years. 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.
These roadway characteristics are then used to help determine an appropriate speed limit. In
addition, the Manual on Uniform Traffic Control Devices (MUTCD, Traffic Operations Policy
Directive 09-04} states that the speed limit shall be established at the nearest Smph increment of
the 85`'' percentile speed. Also, if the Smph reduction is applied, the Engineering and Traffic
Survey shall document in writing the conditions and justification for the lower speed limit and be
approved by a registered Civil or Traffic Engineer.
Speed limits established on this basis conform to the consensus of those who drive the street as
to what speed is reasonable and safe, and are not dependent on the judgment of one or a few
individuals. Speed limits higher. than the 85th percentile speed are not generally considered
reasonable and safe while speed limits below the 85th percentile typically do not facilitate the
orderly movement of traffic. Only when roadside development results in traffic conflicts or
unusual conditions not readily apparent to drivers may speed limits be further reduced.
Physical Conditions:
La Media Road between Olympic Parkway and Birch Road/State Street is 2,845 feet (0.54 miles)
long and 104'-121' wide curb-to-curb. The street is classified as a Six-Lane Major. Bilce lanes
exist along both sides of the segment and no parking is allowed. Fire Station No. 7 is located on
Santa Venetia Street, just west of La Media Road.

Parking and Bike No Parking allowed. Bike lanes are located along the entire segment in both
Facilities directions.
Residential and multi-family residential with no direct driveway access or
Land Use frontage.
A horizontal curve located approximately 160' south of Olympic Parkway with
Horizontal Alignment a radius of 4400' over a length of 375' along the centerline produces a design
s eed eater than 60 m h.

Vertical Alignment o

The accident rate at this segment is 0.00 (accidents per million vehicle miles)
Accident Rate: and is lower than the rate of 1.70 for similar roadways in the State of California
Segment /State (2008).
Fire Station No. 7 is located at the intersection La Media Rd and Santa Venetia
Special Conditions Street. Otay Ranch High School is located within proximity of 920' of La
Media Rd. Bike lanes are located alon the entire se ent.
CONCLUSION
Based on the 85t~' percentile speed of the roadway, as well as other roadway characteristics
outlined in the Engineering/Traffic Survey, staff has determined that the 45 mph speed limit
should be established along La Media Road.
Should the City Council establish the proposed 45 mph speed limit, Schedule X of the register
maintained in the office of the City Engineer would be revised to show the following:
10.48.020 Schedule X -Established Speed Limits in Certain Zones -Designated
Name of Street Beginning At Ending At Proposed Speed Limit
La Media Road Olympic Parkway Birch Road/State
Street 45 mph
DECISION MAKER CONFLICT
Staff has reviewed the property holdings of the City Council and has found no property holdings
within 500 feet of the boundaries of the property, which is the subject of this action.

CURRENT YEAR FISCAL IMPACT
The cost for the speed limit signs has been paid by the developer. These signs will be re-
installed as part of the City's Pavement Rehabilitation Program that is budgeted in the Capital
hnprovement Program for fiscal year 2011-12. Therefore, there is no fiscal impact as a result of
approving this ordinance.
ONGOING FISCAL IMPACT
There is no ongoing fiscal impact as a result of approving this ordinance.
