NATIONAL CITY TRAFFIC SAFETY COMMITTEE
AGENDA REPORT FOR MAY 8, 2013
ITEM TITLE:
ITEM NO. 4013-09
REQUEST FOR SAFETY ENHANCEMENTS ON CAGLE
STREET BETWEEN STOCKMAN STREET AND MENARD
STREET INCLUDING INSTALLATION OF ALL -WAY STOP
CONTROL AT THE INTERSECTION OF CAGLE STREET AND
MENARD STREET (BY NEIGHBORHOOD RESIDENTS)
PREPARED BY: Stephen Manganiello, City Engineer
DISCUSSION:
Several residents contacted staff with concerns regarding speeding, lack of curve
warning signs and visibility constraints along Cagle Street between Stockman Street and
Menard Street. Review of traffic collision history indicated no "reported" accidents within
recent years. The City previously installed a series of speed humps further east on
Cagle Street to slow traffic.
Staff performed an initial site evaluation and presented findings and recommendations to
the Traffic Safety Committee on February 20, 2013 (TSC Item No. 2013-2). Staff's
recommended was to install curve warning signs for both directions of travel.
Approximately 20 feet of red curb "No Parking" was also recommended to accompany
the proposed curve warning signs at the curve on the 3100 block of Cagle Street to
discourage vehicles from parking and blocking the signs. The Committee voted
unanimously to approve the staff recommendation.
TSC Item No. 2013-02 was then presented to City Council on March 5, 2013 for
approval. After listening to comments from the public and asking questions of staff, City
Council directed staff to perform a new site assessment to review the proposed type and
location of signs and amount of red curb on Cagle Street. City Council also directed
staff to evaluate the need for All -Way Stop Control at the intersection of Cagle Street
and Menard Street.
Staff performed a follow-up site evaluation and confirmed that 20 feet of red curb "No
Parking" would be required to accompany the proposed curve warning signs at the curve
on the 3100 block of Cagle Street to discourage vehicles from parking and blocking the
signs. Staff also reviewed site distance for vehicles and pedestrians at the intersection
of Cagle Street and Menard Street, a "T" intersection which is currentiy Stop controlled
for the south leg and uncontrolled for the east and west legs.
In accordance with the latest edition of the California Manual on Uniform Traffic Control
Devices (MUTCD), Section 2B.07 "Multi -Way Stop Applications" provides guidelines for
considering the need for installing multi -way Stop signs at intersections. Poor visibility
may be considered for justifying multi -way Stop control at, "Locations where a road user,
after stopping, cannot see conflicting traffic and is not able to negotiate the intersection
unless conflicting cross traffic is also required to stop."
For speeds of 3U MPi-i, the Galtrans Highway Design Manual (HDM) and American
Association of State Highway and Transportation Officials (AASHTO) require a minimum
stopping sight distance of 200 feet. Based on the roadway curvature for both the
eastbound and westbound approaches to the intersection of Cagle Street and Menard
Street, the minimum stopping sight distance requirement is not met. This considers
vehicles stopped on Menard Street and pedestrians crossing the far side of the
intersection,
Sections 21354 and 21355(a) of the California Vehicle Code provide authority to local
agencies to erect Stop signs at any location in their respective jurisdictions so as to
control traffic within an intersection.
STAFF RECOMMENDATION:
In order to enhance safety for both drivers and pedestrians along Cagle Street between
Stockman Street and Menard Street, staff recommends the following:
1) Install 20 feet red curb No Parking" at the curve on the 3100 block of Cagle
Street to accommodate refiectorized chevron curve warning signs (W1-8) for
eastbound traffic and discourage vehicles from parking and blocking the signs;
2) Install a curve ahead warning sign (W1-2) with 20 MPH plaque for eastbound
traffic;
3) install All -Way Stop Control at the intersection of Cagle Street and Menard Street
with Stop Ahead warning signs and pavement markings in advance of the
intersection for eastbound and westbound approaches;
4) Install 25 feet red curb "No Parking" as required in advance of the new Stop
signs for eastbound and westbound approaches to the intersection of Cagle
Street and Menard Street.
