STAFF €PORT
TO: THE HONORABLE CHAIRMAN AND COMMISSIONERS
FROM: JOANNE ITAGAKI, TRAFFIC ENGINEERING DEPUTY
DATE: DECEMBER 4, 2008
SUBJECT: JACKSOE~I AVENUE/GARVALIA AVENUE - PROPOSE® STOP SIGN?
INSTALLATION
BACI(GROUND
In September 2008, the Traffic Commission reviewed a request regarding speeding on
Jackson Avenue between Fern Avenue and Graves Avenue. Residents also asked for
the .installation of stop signs to slow traffic. Staff analyzed the intersection of Jackson
Avenue/Garvalia Avenue for the installation of a multi-way stop. The Ca{ifornia Manual
on Uniform Traffic Control Devices (CP. MUTCD) guidelines were not satisfied.
However, after discussion regarding the intersection of Jackson Avenue/Garvalia
Avenue; the Traffic Commission determined that vehicles traveling on Jackson Avenue
could .not be seen from Garvalia Avenue. Based on those concerns staff concurred that
there were existing visibility constraints at the location and based on that finding, it vdas
initially recommended that the stop signs not be installed. That could not be addressed
through the installation of parking restrictions or the trimming of trees. Therefore, the
Traffic Commission recommended to the City Council the installation of STOP signs on
Jackson Avenue at Garvalia Avenue.
The City Council has requested this item be brought back to the Traffic Commission.
®ISCUSSION
As discussed at the September 2008 Traffic Commission meeting, the CA MUTCD
provides criteria/guidelines for the use of STOP signs. For the intersection of Jackson
Avenue/Garvalia Avenue, the criteria for "Multiway Stop Applications" were analyzed.
The analysis indicated that the subject .intersection did not satisfy these criteria.
However, the CA MUTCD allows for consideration of "other criteria" to be considered
including:
A. The need to control left-turn conflicts;

B. The need to control vehicle/pedestrian conflicts near locations that generate
high pedestrian volumes;
C. Locations where a road user, after stopping, cannot see conflicting traffic
and is not able to reasonably safely negotiate the intersection unless
conflicting cross traffic is also required to stop; and
D. An intersection of two residential neighborhood collector (through) streets of
similar design and operating characteristics where multiway stop control
would improve traffic operational characteristics of the intersection."
Based on item C (above), it is feasib{e to recommend the installation of STOP signs on
Jackson Avenue at Garvalia Avenue.
Recommendation
Based on the discussion made by the Traffic Commission and field observations of the
intersection in September 2008, the Traffic Commission recommended the City Council
install STOP signs oi-~ Jackson Avenue at Garvalia Avenue. City staff concurs with the
recommendation of the Traffic Commission.
