TO: WILLIAM A. HUSTON, CITY MANAGER
FROM: PUBLIC WORKS DEPARTMENT/ENGINEERING DIVISION
SUBJECT: STATUS REPORT - 1992 CONGESTION MANAGEMENT PROGRAM (CMP) LEVEL
OF SERVICE UPDATE
RECOMMENDATION:
Receive and.file.
BACKGROUND:
In accordance with the current Orange County CMP guidelines, the
County of Orange is responsible for providing levels of service to
Orange County cities for streets designated on the Orange County
CMP Highway System. Within the City of Tustin, Jamboree Road,
Irvine Boulevard, and Edinger Avenue are identified on the CMP
Highway System.
DISCUSSION:
In April 1992, the City of Tustin received materials submitted by
the Orange County Environmental Management Agency regarding the
collection of data pertinent to the 1992 level of service
calculations for the CMP Highway System. The calculations were
completed and received by the City of Tustin in June, 1992, and are
summarized in the attached exhibits.
Also, attached to this report is a comparison of levels of service
for roadway links and intersections on the CMP Highway System
within•Tustin for 1991 and 1992. Particular attention is directed
to the intersections of Irvine Boulevard/Jamboree Road and Edinger
Avenue/Jamboree Road. These intersections show significant
decreases in levels of service from 1991 to 1992. This is
attributed primarily to commuter traffic on Jamboree Road. Since
its September 1991 opening through the Marine Corps Air Station,
Jamboree Road has been used as a bypass route by commuters to avoid
traffic congestion on the SR -55 Freeway. The impact of this to the
City of Tustin is not only an increase in traffic congestion within
the City, but also the future possibility that its levels of
service may exceed CMP requirements, with the possible loss of CMP
funding if suitable improvements are not implemented.
Staff has recognized a potential concern with the level of service
at the Jamboree Road/Edinger Avenue intersection and with City
Council concurrence in Spring 1992, submitted two projects to the
County for Measure M funding that would enhance the intersection
traffic capacity and provide full major arterial highway widening
.of Edinger Avenue from Harvard Avenue to west of Jamboree Road.

JULY 20, 1992

Unfortunately, Measure M funding for these projects was denied
under the first year call for projects. However, it is envisioned
at this time that with the Eastern Transportation Corridor, an
overcrossing of Edinger Avenue by Jamboree Road will be pursued by
the Transportation Corridor Agencies (TCA) in accordance with the
TCA Board's actions of May 14, 1992. Also, Measure M funding for
the widening of Edinger Avenue to its full 6 -lane major arterial
width in this area may be reapplied for in the next call for
Measure M projects in Fall, 1992.
The capacity along Irvine Boulevard will increase with the
implementation of the County of Orange's Irvine Boulevard Widening
and Restriping Project, which is currently in the environmental
stages. Implementation of that project will provide a 6 -lane
facility where only 4 -lanes exist today.
The level of service at the intersection of Irvine
Boulevard/Jamboree Road will be enhanced with the future
implementation of a third northbound through lane on Jamboree Road
from the I-5 Freeway to Irvine Boulevard, and also with the
completion of the East leg of the Irvine Boulevard/Jamboree Road
intersection, which is in the County. The City's seven year CMP
Capital Improvement Program currently calls for utilizing
Proposition 111 funds on the Jamboree Road widening as well as
County of Orange funds since a portion of this link (I-5 Freeway to
Bryan Avenue) lies within the unincorporated area.
It should also be indicated that current I-5 and SR -55 Freeway
construction is having a significant impact on City streets due to
traffic diversion from the freeways onto the local arterial system.
In conclusion, the City of Tustin remains in compliance with the
current CMP requirements provided the levels of service do not
deteriorate below level E. As can be seen in the attachment, the
City of Tustin in terms of 1992 reporting is within CMP compliance
at this time.
This is a status report only and no Council action other than
receive and file is necessary at this time.
