CITY COUNCIL AGENDA
ITEM NO. 16
TO: MAYOR AND MEMBERS OF THE CITY COUNCIL
FROM: PUBLIC WORKS DEPARTMENT
SUBJECT: SANTIAGO DRIVE STATUS REPORT
Staff continues to work with OCTA, Costa Mesa and the County of Orange to reclassify
the segment of Santiago Drive between Irvine Avenue and Tustin Avenue from a
Secondary Arterial to a Collector Arterial. We have just completed the necessary Traffic
Study to analyze impacts to other streets resulting from the reclassification. The City of
Costa Mesa had asked for a number of specific impacts to be studied. A copy of their
letter is attached for your information.
The Traffic Study has been mailed to OCTA, Costa Mesa and the County of Orange for
review and comment. Their responses are due back by October 2, 1998. Additional
studies may be required depending upon the input from these other agencies.
A copy of the Traffic Study has also been sent to the spokesperson for the residents on
Santiago Drive. Additional copies are available in the Public Works Department.
The next step will be the formal application to OCTA for the reclassification. They will
only approve the reclassification if Costa Mesa and the County are in agreement. I
anticipate that the County will have no objections. In fact, the study indicates that they
would be able to reclassify the segment of Santiago Drive between Tustin and Santa Ana
Avenues and they are likely to do so.
Costa Mesa staff has expressed concerns about the potential impact of the
reclassification on other streets in the area. The Traffic Study was specifically intended to
address those concerns and should be adequate. The study does show that there will be
a small (less than 500 cars per day) increase on several of the east -west streets between
17'' Street and Santiago Drive. Changes of this magnitude should not be noticeable to
residents along these streets and hopefully they will not be the basis for objections by
Costa Mesa.
Respectfully sub fitted,
Public Works Department

SUBJECT: RECLASSIFICATION OF SANTIAGO DRIVE /22ND STREET
Dear Mr. Edmonston:
Thank you for your letter of December 18, 1997, providing notice for the preparation
of a Request For Proposal (RFP) for the necessary traffic analysis to document the
impact of reclassifying Santiago Drive /22nd Street, between Irvine Avenue and
Newport Boulevard, from a Secondary Arterial to a Collector Arterial. A segment of
this street is within the city limits of Costa Mesa and comprises a full 50 percent of
the affected street. I am, therefore, most interested in this process and that the scope
of work includes specific issues that are of the utmost importance to our community.
The City of Newport Beach, in cooperation with the City of Costa Mesa through the
Santa Ana River Crossing (SARX) study, was involved in the past downgrading of
East 191h Street between Irvine Avenue and Newport Boulevard. As a result, I am
sure you are aware of the major issues of interest to Costa Mesa regarding the need
for a higher level arterial between 17th Street and Del Mar Avenue/University Drive.
The recently completed East Side Residential Traffic Management Study, with which
we were both also involved, identified that the possible diversion of traffic to
paralleling local streets, particularly in the vicinity of freeway access, is a well-
documented concern of our residents. The loss of a future, secondary arterial to /from
the SR -55 Freeway will likely have a bearing on future residential traffic patterns.
The RFP should, at a minimum, include the following items:
• Analysis of Post 2010 Level of Service at the cross streets of Santiago Drive /22nd
Street with Santa Ana Avenue, Orange Avenue, and Newport Boulevard.
• Analysis of the Post 2010 Traffic Projections on Del Mar Avenue, between Irvine
Avenue and Newport Boulevard.
• Santa Isabel, as the nearest collector arterial with east/west circulation across the
SR -55 Freeway, requires analysis of Post 2010 Traffic Projections between Irvine
Avenue and Newport Boulevard, including its intersections at Tustin Avenue,
Santa Ana Avenue, Orange Avenue, and Newport Boulevard.
• Analysis of possible future diversion of traffic on Virginia Place and Cecil Place,
between Santa Ana Avenue and Newport Boulevard, as an alternative access
route to the northbound SR -55 on ramp.
• Analysis of traffic diversion on other residential streets that provide a through
connection between Irvine Avenue and Newport Boulevard under Post 2010
conditions.

The downgrading of East 191h Street as well as the East Side Study relied on the
future improvements specified in the present Master Plan of Arterial Highways,
including future widening of Santiago Drive /22nd Street. In light of these issues, I
appreciate the opportunity to work with you on this study and address items of
mutual interest to both of our communities.
If you have any questions, please contact me at (714) 754 -5182.
