A 50 MPH SPEED LIMIT ON HUNTE PARKWAY BETWEEN
EASTLAKE PARKWAY AND OLYMPIC PARKWAY AND
AMENDING SCHEDULE X OF THE REGISTER MAINTAINED IN

ESTABLISHED SPEED LIMIT

4/STHS VOTE: YES ^ NO
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 50 mph speed limit be established on Hunte Parkway between
Olympic Parkway and Eastlake Parkway.
ENVIRONMENTAL REVIEW
The Director of Development Services has reviewed the proposed activities for compliance 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 June 1, 2011 meeting of the Safety Commission, a motion was made to accept staff s
recommendation and approve the establishment of the 50 mph posted speed limit on Hunte
Parkway between Olympic Parkway and Eastlake Parkway. The motion carried by a vote of
6 (in favor) - 0 (opposed) - 1 (absent).

DISCUSSION
Currently, there are no speed limit signs posted on Hunte Parkway between Olympic Parkway
and Eastlake Parkway. 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 Hunte Parkway without an impact of any roadside or nearby development and /or
construction. Now that construction activity and the one-year maintenance period within this
roadway has been completed and accepted by the City, the speed limit can be established.
City staff completed a speed survey along Hunte Parkway between Olympic Parkway and
Eastlake Parkway 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 (2010 MUTCD, Traffic Operations
Policy Directive 09-04) states that the speed limit shall be established at the nearest 5mph
increment of the 85`h 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 85`h percentile speed are not generally considered
reasonable and safe while speed limits below the 85`h 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:
Eastlake Parkway between Olympic Pazkway and Hunte Parkway is 8,534 feet (1.62 miles) long
and 104'-120' wide curb-to-curb. The street is classified as a Six-Lane Major. High Tech
High/Middle and Elementary schools are located at the intersection with Discovery Falls Drive.
Bike lanes exist along both sides of the segment and no parking is allowed. At the intersection
of Hunte Parkway and Eastlake Parkway, the three thru lanes and the dual left-turn lanes are
closed and traffic is diverted to the two right-turn lanes.

CONCLUSION
Based on the 85`h percentile speed of the roadway, as well as other roadway characteristics
outlined in the Engineering/Traffic Survey, staff has determined that the 50 mph speed limit
should be established along Hunte Parkway.
Should the Safety Commission, and ultimately City Council, establish the proposed 50 mph
speed limit, Schedule X of the register maintained in the office of the City Engineer would be
revised to show the following:

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 establishment of the speed limit would require the posting of new speed limit signs and
speed limit legends. The required signing and striping will be constructed and completed by the
developer as part of development requirements. Therefore, there is no fiscal impact to the City
beside on-going regular maintenance.
ONGOING FISCAL IMPACT
There will only be minor routine maintenance costs in 7 to 10 years. The eligible funding
source is Transnet or Gas Tax.
