III. REQUEST:
City Initiated
THAT SPEED LIMIT FOR CHERRYWOOD STREET FROM GARVEY
AVENUE SOUTH TO NORMA AVENUE BE REDUCED FROM 35 MILES-
PER-HOUR TO 30 MILES-PER-HOUR AND SPEED LIMIT FOR
CALVADOS AVENUE FROM GARVEY AVENUE SOUTH TO NORMA
AVENUE BE REDUCED FROM 35 MILES-PER-HOUR TO 25 MILES-
PER-HOUR.
FINDINGS:
The speed limits on Cherrywood Street and Calvados Avenue are specified in
Section 22-131 of the West Covina Municipal Code as 35 miles-per-hour from
Garvey Avenue South to Norma Avenue. Staff conducted an Engineering and
Traffic Survey for Garvey Avenue South (See EXhibit A) and found that the critical
approach speed was measured at 28 miles-pet-hour on Cherrywood Street and 25
miles-per-hour on Calvados Avenue. In accordance with California Manual of
Uniform Traffic Control Devices (MUTCD), speed limits should be established at
the nearest 5 miles-per-hour increment to the 85 th percentile speed, which is defined as that speed which 85 percent of the traffic is moving. Therefore, the reduction in
the posted speed limit from 35 miles-per-hour to 30 miles-per-hour for Cherrywood
Street from Garvey Avenue South to Norma Avenue and 35 miles-per-hour to 25
miles-per-hour for Calvados Avenue from Garvey Avenue South to Norma Avenue
will comply with provision of the California MUTCD.
TRAFFIC COMMITTEE RECOMMENDATION:
THAT AN ORDINANCE BE INTRODUCED AMENDING SECTION 22-
131 OF THE WEST COVINA MUNICIPAL CODE RELATING TO T1TE
REDUCTION OF THE POSTED SPEED LIMITS ON THE FOLLOWING
STREET SEGMENTS:
1. CHERRYWOOD STREET FROM GARVEY AVENUE SOUTH TO

ENGINEERING AND TRAFFIC SURVEY OF GARVEY AVENUE SOUTH
Introduction:
The effective enforcement of posted speed limits with radar on certain streets requires
that an Engineering and Traffic Survey must be completed within the previous five
years. The majority of drivers complies with the law but disregard regulations that they
consider unreasonable. A small segment of the population is repeatedly inclined to be
reckless, unreliable, or have faulty judgment and must be controlled by enforcement.
According to the Manual of Uniform Traffic Control Devices (MUTCD), speed limits
should be established at the nearest 5 mph increment to the 85 th percentile speed, which
is defined as that speed at or below which 85 percent of the traffic is moving. The 85 th
percentile is often referred to as critical speed. Pace speed is defined as the 10-mile
increment of speed containing the largest number of vehicles. Speed limits higher than
the 85th percentile are not considered reasonable and prudent. Speed limits below the
85 1 percentile do not ordinarily facilitate the orderly movement of traffic and require
constant enforcement to maintain compliance.
The establishment of a speed limit of more than 5 miles per hour below the 85
percentile (critical) speed must be justified in the engineering and traffic survey and
approved by a registered Civil or Traffic Engineer. It should also be done with great
care as studies have shown that establishing a speed limit at less than this the 85
percentile generally results in an increase in collision rates and may make violators of a
disproportionate number of the reasonable majority of drivers.
Section 22358 of the Vehicle Code states that it is the intent of the Legislature that
physical conditions such as width, curvature, grade and surface conditions, or any
condition readily apparent to the driver, in the absence of other factors, would not
require special downward speed zoning. When roadside developments results in traffic
conflicts and unusual conditions which are not readily apparent to the driver, as indicated
in collision records, speed limits some what below the 85 th percentile may be justified.

B. Accident Records
The following analysis of the accident history for Garvey Avenue South is in
accordance with the procedures outlined in "Guidelines for Uniform Traffic
Controls" distributed by the Los Angeles County Department of Public Works.
County guidelines classify as excessive any accident rate that exceeds1.6 times
the County expected rate determined from the countywide experience charts. If
the City mid-block accident rates are in excess of the 1.6 times the County
expected rate, a 5 mph reduction of the speed limit may be justified. This is to
say that if the Priority Rating meets or exceeds 1.6, a 5-mph reduction of the
speed limit from the critical approach speed (85%) may be justified..

NOTE:A/MV denotes accidents .per million vehicles entering the intersection.
C. Physical Conditions
1. Horizontal Alignment - Mostly tangent, all curves are posted with advisory signs
where warranted.
2. Vertical alignment - Maximum grades occur at freeway underpasses with grades
that range from -4.1% to +6.1%. The remaining segments have relatively gentle
slopes that range between -0.8% to +1.1%.
3. Roadside Friction - Garvey Avenue South is broken into several independent
segments. Minor intersections provide no significant conflict. The intersection of
Garvey Avenue South and Orange Avenue has a "T" type configuration and is
controlled by a stop sign on Garvey Avenue South. All other major intersections
are controlled by traffic signals. There are commercial, multi-family and single
family residences abutting Garvey Avenue South. Along the segment between
Citrus Avenue and Ban-anca Street, there is a "T" type intersection With on-ramp
and off-ramp to the 1-10 freeway and is controlled by a stop sign at the off-ramp.
Between Barranca Street and Holt Avenue, there is a "T" type of intersection with
on-ramp and off-ramp to the 1-10 freeway and is control by a stop sign on the
westbound approach of Garvey avenue South and at the off-ramp.
D. Conditions Not Readily Apparent To The Driver.
None
E. Analysis
The first table entitled " Prevailing Speeds" list the critical approach speeds (85%)
which is the primary component of Engineering and Traffic Survey. The 85%
speed is listed for each of the eleven segments of Garvey Avenue South. The
critical approach speeds (85%) are generally within 5 mph of the posted speed
limit. The critical approach speeds (85%) for the nine of the eleven segments of
Garvey Avenue .South are within 5 mph of the posted speed limit.
Garvey Avenue South
September 28, 2011
F. Conclusion
Retention of the existing speed limits for the nine of the eleven segments of
Garvey Avenue South will comply with the provision of the California MUTCD.
Presently the posted speed limit for the segment of Cherrywood Street from
Garvey Avenue South to Norma Avenue is 35 mph and the critical approach
speed was measured at 28 mph and the posted speed limit for the segment of
Calvados Avenue from Garvey Avenue South to Norma Avenue is 35 mph and
the critical approach speed was measured at 25 mph. In accordance with the
provision of the California MUTCD, speed limits should be established at the
nearest 5 mph increment to the 85`11 percentile speed, which is defined as that
speed which 85 percent of the traffic is moving. Therefore, the reduction in the
posted speed limit from 35 mph to 30 mph for Cherrywood Street from Garvey
Avenue South to Norma Avenue and the reduction in the posted speed limit from
35 mph to 25 mph for Calvados AVenue from Garvey Avenue South to Norma
Avenue. Cherrywood Street and Calvados Avenue will comply with provision of
the California MUTCD; the following speeds shall be reduced along Garvey
Avenue South:
LIMITS SPEED LIMIT
West City Limit to Orange Avenue 40 mph
West Covina Parkway to Sunset Avenue 40 mph
Glendora Avenue to Lark Ellen Avenue 35 mph
