MAIN STREET TRAFFIC CONTROLS (MAIN STREET AT 'B' STREET INTERSECTION
RECOMMENDATION:
Staff recommends three separate actions related to the Main Street and "B" Street
intersection:
A. That the Tustin City Council not authorize a four-way stop sign
installation at the subject-intersection.
Be
That the California Pepper tree at the southwesterly corner be
removed and red zones be installed at the easterly and westerly
Main Street approaches.
C. That a traffic signal not be installed at the subject intersection
at this time.
BACKGROUND:
On April 7, 1986, the City Council considered and approved the installation of a
traffic signal at the intersection of Main Street and Pacific Street and, the
Tustin Community Redevelopment Agency appropriated funds in the amount of
$99,000.00 for said work.
The intersection of Main Street and "B" Street was also briefly discusse-d at that
meeting, but staff requested that any decisions related to this intersection be
continued until such time a current warrant study for a four-way stop sign
installation could be completed.
DISCUSSION:
The warrant studies for both a traffic signal and four-way stop sign installation
at Main Street and "B" Street were completed on April 23, 1986 with the following
results:
° The intersection meets the warrants for a traffic signal installation
but does not meet the warrants for a four-way stop sign installation.
In the event a traffic signal is installed at this intersection a four-way stop
sign could be installed during the design and construction phase of the traffic
signal, but only if a traffic signal is ultimately installed.
APRIL 28, 1986

The City's Consultant Traffic Engineer recommends against the installation of a
traffic signal at Main Street and "B" Street. The warrants for a traffic signal
installation were barely satisfied.
The accident history at this intersection is as follows:
1983 - Three right angle type
1984 - One right angle type
1985 - Four right angle type
1986 to Date - Two right angle type
The estimated installation cost of a traffic signal at this intersection is
$85,000 with an on-going estimated monthly energy and maintenance cost of
$228.00. {Signal energy - $105; Safety light energy - $60; Signal maintenance -
$63).
The re-investigation of this intersection revealed two areas of concern which have
been reported in previous investigations and require action as follows:
1. California Pepper tree on southwesterly corner of Main Street at
"B" Street impairs visibility and should be removed.
A minimum of 60 feet of red zones should be installed at both the
easterly and westerly approaches of Main Street to provide improved
visibility for motorists utilizing "B" Street to approach Main Street.
