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 40 mph speed limit be established on Mount Miguel Road
between Proctor Valley Road/East `H' Street and SR-125.
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 September 7, 2011 meeting of the Safety Commission, a motion was made to accept
staff's recommendation and approve the establishment of the 40 mph posted speed limit on
Mount Miguel Road between Proctor Valley Road/East `H' Street and SR-125.
The motion carried by a vote of 5 (in favor) - 0 (opposed) - 2 (absent).

DISCUSSION
Currently, there are 35 mph posted speed limit signs on Mount Miguel Road between Proctor
Valley Road/East `H' Street and SR-125. The developer installed these signs as a continuation
of the existing 35 mph posted speed limit at Mount Miguel Road between East "H" Street and
Mackenzie Creek Road. 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 Mount
Miguel Road without an impact of any roadside or nearby development and /or construction.
Now that constriction 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 Mount Miguel Road between Proctor Valley
Road/East `H' Street and SR-125 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`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 85t1i 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. If the
speed limit were to be 35 mph, approximately half of the vehicles would be considerably over
the posted speed limit.
Physical Conditions:
Mount Miguel Road between Proctor Valley Road/East `H' Street and SR-125 is 6,098 feet (1.15
miles) long and 74' wide curb-to-curb with a 10' raised median. The street is classified as a
Class I Collector. Mount San Miguel Park is located on the northeast corner of Mount Miguel

CONCLUSION
Based on the 85"' percentile speed of the roadway, as well as other roadway characteristics
outlined in the Engineering/Traffic Survey, staff has determined that the 40 mph speed limit
should be established along Mount Miguel Road.
Should City Council establish the proposed 40 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 cost of the new signs necessary to implement the proposed speed limit modification is part
of the City's Pavement Rehabilitation Program that is budgeted in the Capital Improvement
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.
