DATE: JANUARY 7, 2004
RE: REQUEST FOR TRAFFIC CONTROLS FOR THE ALLEY WEST OF
WALNUT GROVE AVENUE BETWEEN FERN AVENUE AND
KLINGERMAN AVENUE
A resident has requested traffic controls for the alley west of Walnut Grove Avenue, between
Klingerman and Fern Avenues. The concern is with speeding and the use of the alley as a short
cut. Although the resident wants "speed bumps", City policy has been not to install such
devices. Staff is concerned with vehicles losing control and damaging private property.
The Commission approved the staff recommendation of no "speed bumps" with the addition of
installing two (2) 15 mph signs at each end and selective enforcement. Attached is a copy of the
staff report and the minutes from the December 4, 2003 Commission meeting.
RECOMMENDATION
It is recommended that the City Council approve the Traffic Commission's recommendation to
deny traffic controls for the alley west of Walnut Grove Avenue between Fern and Klingerman
Avenues. It is further recommended that staff be directed to install two (2) 15 mph signs and
continue selective enforcement.

ROSEMEAD TRAFFIC COMMISSSION
FROM: JOANNE ITAGAKI, TRAFFIC ENGINEERING DEPUTY
DATE: November 24, 2003
RE: Request for Traffic Controls in the Alley West of Walnut Grove
Avenue between Fern Avenue and Klingerman Avenue
REQUEST
Mr. Eddie Ochoa, 2409 Walnut Grove Avenue, has requested the City to review
the conditions in the alley west of Walnut Grove Avenue between Fern Avenue
and Klingerman Avenue. Mr. Ochoa is concerned with the speeding and cut-
through traffic using this alley. He indicated that most of the speeding and cut-
through seems to occur with the start and release periods of Sanchez
Elementary and Temple Intermediate schools.
CONDITIONS
The alley west of Walnut Grove Avenue between Fern Avenue and Klingerman
Avenue is approximately 20 feet wide with a concrete drain pan running down the
middle of the alley. On the east side of the alley are the wall/fences and garage
access of the residential homes fronting on Walnut Grove Avenue. On the west
side of the alley is the sports park and school grounds. There is a gated entry to
the school grounds directly across from Andy Pacheco Court.
Andy Pacheco Court breaks the alley into two sections. The intersection of the
alley and Andy Pacheco Court is controlled by stop signs in all directions.
DATA
Turning movement counts into and out of the alley at Fern Avenue and Walnut
Grove Avenue were taken during the morning (7:00 to 9:00) and afternoon (4:00
to 6:00) peak hours. This data identified the 7:30 AM and 4:00 PM hours as
having the peak turning movement volumes. The following was observed:,

Speed data was also collected for vehicles traveling in the alley. This data was
collected for a half-hour period starting at 7:15 AM. The speed data is
summarized below-
# observed Highest Lowest 85"' %
North of Andy Pacheco Ct. 14 37 mph 13 mph 30 mph
South of Andy Pacheco Ct. 21 35 mph 18 mph 35 mph
DISCUSSION
Field observations were done in the morning start times of Sanchez Elementary
and Temple Intermediate schools. During these observations, vehicles were
identified traveling at speeds greater than the 15 mph speed limit for alleys. 6
vehicles of the 35 total vehicles observed were traveling at or above 30 mph. It
was difficult to determine exactly which vehicles were using the alley as a "cut-
through". However, it appeared that possibly 8 to 10 vehicles observed went
through the alley from Klingerman Avenue to Fern Avenue or vise versa.
Currently, the City policy is not to install speed bumps within the public right-of-
way. The primary concern with installing speed bumps is there is no recognized
standard design for speed bumps. Specifically with regards to speed bumps in
an alley, staff has concerns with vehicles possibly loosing control and colliding
with the adjacent garages and walls. Unlike streets, the alley doesn't provide a
"buffer" area of sidewalk or yards should a vehicle loose control.
Another concern with the installation of a speed bump in this particular alley is
the presence of a concrete drain area in the center of the alley. This drain area
indicates flow is from the sides of the alley flows north/south out of the alley. A
speed bump could not be installed the width of the alley because it would prohibit
drainage. If the speed bump was installed in two sections avoiding the drainage
area, vehicles would likely drive with one set of wheels in the drainage area and
one set over the speed bumps.
Based on the speed data collected, there are vehicles traveling higher than the
speed limit with alleys. The installation of a speed limit sign may help to inform
motorists of the speed in an alley. However, selective enforcement would be the
most effective in controlling speeds.

With regards to the cut-through traffic, it is difficult to determine why the motorists
may be using the alley as an alternative route. They may perceive problems with
the traffic signals on Walnut Grove Avenue then take the alley. They may also
be traveling to one of the schools and this is an "easier" route.
RECOMMENDATION
The installation of speed bumps in the alley west of Walnut Grove Avenue
between Fern Avenue and Klingerman Avenue is not recommended. Selective
enforcement of speeds in the alley is recommended at this time.

enforcement of speeds in the alley is recommended at this time.
Chairperson Knapp asked about making the alley a one-way street Deputy
Traffic Engineer Itagaki was. concerned about the inconvenience it will cause the
residents. They would have to go around the block to get in or out of their
driveways. '
Chairperson Knapp also recommended the possibility of installing rumble strips.
Deputy Traffic Engineer Itagaki stated that the residents at this location have no
front yards and that the noise factor would affect them even more because of the
closeness to their homes.

carried unanimously to approve the Traffic Engineer's recommendation with the
addition of installing two (2) 15 mph signs at each end and to have selective
enforcement at this location.
