CC - Item 3I - Lengthening Left Turn Lanes Walnut Grove Ave at Hellman•
•
ROSEMEAD CITY COUNCIL
STAFF REPORT
TO: THE HONORABLE MAYOR AND CITY COUNCIL
FROM: ANDREW C. LAZZARETTO, CITY MANAG
DATE: NOVEMBER 28, 2006
SUBJECT: LENGTHENING OF LEFT TURN LANES FOR NORTHBOUND AND
SOUTHBOUND WALNUT GROVE AVENUE AT HELLMAN AVENUE
SUMMARY
The recent traffic signal modification at the intersection of Walnut Grove Avenue and
Hellman Avenue has caused a need for additional storage length for left turn traffic.
This need is in both the northbound and southbound directions. With the new traffic
signal at Hellman Avenue and the 1-10 Freeway ramps and the associated signal
operation, this left turn storage demand is not likely to diminish.
Staff Recommendation
Staff recommends that the City Council approve the Traffic Commission's
recommendation to:
• Lengthen the southbound left turn lane to 120 feet;
• Lengthen the northbound left turn lane to 200 feet;
• Install 85 feet of "No Parking Any Time" on the west side of Walnut Grove Avenue;
and
• Install 185 feet of "No Parking Any Time" on the east side of Walnut Grove Avenue.
ANALYSIS
Field observations during various times of the day revealed that the existing left turn
lanes on Walnut Grove Avenue at Hellman Avenue were not long enough to store all left
turning vehicles. This results in vehicles blocking the Number 1 lanes of through traffic
in each direction. In addition, vehicles wanting to access the left turn lane in the
northbound direction were unable to "sneak" around the vehicles in the Number 1 lane
because of the double yellow centerline separating traffic.
The traffic signal operation at this intersection has changed with the installation of the
traffic signal at the 1-10 ramps. These two signals are connected and work together as
one unit and the left turn storage demand is not likely to diminish.

The extension of the northbound left turn lane will require the removal of parking on
both sides of Walnut Grove Avenue from Hellman Avenue to approximately 380 feet to
the south. On the west side of Walnut Grove Avenue, there will be a removal of
approximately 6 parking spaces. On the east side of Walnut Grove Avenue, there will
be a removal of approximately 7 parking spaces. The number of removed parking
spaces is based on a parking length of approximately 20 feet and the number of
driveways on either side of the street.

Hellman Avenue has caused a need for additional storage length for left turn traffic.
This need is in both the northbound and southbound directions. With the new traffic
signal at Hellman Avenue and the 1-10 Freeway ramps and the signal operation, this left
turn storage demand is not likely to diminish.
Staff Recommendation
It is staffs recommendation that the Traffic Commission recommends the City Council
approve:
• The extension of the southbound left turn lane to 120 feet.
• The extension of the northbound left turn lane to 200 feet.
• The installation of 185 feet of "No Parking Any Time" on the west side of Walnut
Grove Avenue. This will remove approximately 6 parking spaces.

direction separated by a double yellow centerline. Parking in the immediate vicinity of
Hellman Avenue is restricted on the west side of Walnut Grove Avenue. Beyond this

A. REQUEST FOR ADDITIONAL NO PARKING FOR OVER 80
INCHES WIDE SIGN ON WALNUT GROVE AVENUE AT
GRAND AVENUE
Deputy Traffic Engineer Itagaki presented the staff report.
RECOMMENDATION:
It was staff's recommendation that the Traffic Commission recommend the City
Council approve:
• The installation of an additional "No Parking Vehicles Over 80 Inches..."
sign.
• The replacement of the existing No Parking Vehicles Over 80 Inches..."
for southbound Walnut Grove Avenue just south of the City limits due to
extensive graffiti obscuring the sign.
• Selective enforcement of trucks parking in the subject area.
Speaking before the Commission:
Rosa Vasquez
4911 Walnut Grove Avenue
Rosemead, California 91770
Ms. Vasquez thanked the Commission and Mr. Wagner for their assistance. She
was in favor of the sign, but wanted to revise the sign to read: "No Cominercial
Vehicle At Any Time", and placed in front of her house for better visibility when
exiting and entering her driveway. She does not feel that the 2 hour parking is a
solution.
It was moved by Commissioner Knapp, seconded by Commissioner Masuda,
and carried unanimously to approve the Traffic Engineer's recommendation,
with the addition of painting red curb on both sides of Mrs. Vasquez's driveway
(in the middle) to Grand and not install a sign at this time.
