SUBJECT: APPROVE TRAFFIC SIGNAL MODIFICATION PLANS FOR RADAR
DETECTION AT RED HILL AVENUE INTERSECTIONS WITH VALENCIA
AVENUE, INDUSTRIAL DRIVE -PARKWAY LOOP, EDINGER AVENUE AND
MITCHELL AVENUE AS PART OF THE ORANGE COUNTY SANITATION
DISTRICT PROJECT
SUMMARY
The traffic signal modification plans for radar detection at Red Hill Avenue intersections with
Valencia Avenue, Industrial Drive -Parkway Loop, Edinger Avenue and Mitchell Avenue Project
were prepared by the City's consultant, Hartzog-Crabill Inc. The plans will be forwarded to the
Orange County Sanitation District (OCSD) for inclusion in the Gisler -Red Hill System
Improvements Sewer Project.
RECOMMENDATION
It is recommended that the City Council approve the plans and specifications for the installation
of radar detection along Red Hill at the intersections of Valencia Avenue, Industrial Drive —
Parkway Loop, Edinger Avenue, and Mitchell Avenue.
FISCAL IMPACT
There is no fiscal impact related to the approval of the plans. The funding to implement the
radar installation plans will entirely be the responsibility of OCSD as a related project cost.
CORRELATION TO THE STRATEGIC PLAN
This item contributes to the fulfillment of the City's Strategic Plan Goal G: Strong Community
and Regional Relationships. Specifically, by implementing Strategy 2, which encourages
working collaboratively with agencies outside Tustin on issues of mutual interest and concern to
the parties.
DISCUSSION AND BACKGROUND
The Orange County Sanitation District (OCSD) has been developing the Gisler -Red Hill System
Improvements and coordinating with City staff over the last year. The proposed OCSD project
consists of repairing two parallel sewers, a trunk and an interceptor that were constructed in the
1960s. The project is located primarily along Red Hill Avenue from Mitchell Avenue in the City of
Tustin to McGaw Avenue in the City of Irvine.
From approximately Warner Avenue to Valencia Avenue, the new sewer line will be located along
the proposed widened section on the easterly side of Red Hill Avenue that is currently unpaved.
From Valencia Avenue to Edinger Avenue, the pipeline will be located in the paved street. The
project also includes new manholes and a short section of pipeline on Red Hill Avenue south of the
intersection of Red Hill Avenue and Mitchell Avenue.

Due to the heavy traffic volumes on Red Hill Avenue, certain segments of the work will be done
during nights and weekends to minimize disruption. Construction of the OCSD project is
tentatively scheduled to begin in February 2016 and will take approximately 20 months. The
City requested radar detection installation prior to construction, thereby replacing existing in
pavement vehicle detection loops subject to interruption during construction. Radar detection
will ensure traffic signal operations are maintained in an effective and efficient manner during
the course of construction and will provide staff flexibility to adjust, if necessary, during various
stages of construction to enhance traffic flow along Red Hill Avenue, which currently carries an
average daily traffic (ADT) of 30,000 vehicles.
