ADNIMISTIZATIVE PROCEDURES FOR IMPLEMENTING
THE TRAFFIC PHASING ORDINANCE
I. Administrative Procedures
A. General:
These procedures apply to all projects which have an Average
Daily Trip generator of more than 300 daily trips.
B. Evaluating Projects:
1. The applicant files a request for consideration of the
entire project, under the provisions of the Ordinance
with the Planning Department The request must be
accompanied by a project description, project phasing
schedule, site plan, and fees as set by the City Council.
2. A traffic analysis shall then be prepared by a qualified
traffic engineer under contract to the City according to
the methodology approved by the City Council.
3. The traffic analysis shall evaluate the traffic generated
from all proposed land uses. Subject to the provisions of
sub - section B.4., in the case of conversion of an existing
building to a more intense land use, the incremental
difference in traffic generated by the development shall
be evaluated.
4. Traffic generated by both existing and proposed land
uses shall be evaluated for any project proposed
subsequent to, and within the time frame for analysis
used by (one year subsequent to the anticipated date of
occupancy), a previously approved Traffic Study.
C. Staff Recommendation:
1. The City's Traffic Engineer will review the report
prepared by the consultant and transmit the findings and
worksheet to the Planning Department for presentation
to the Planning Commission.

D. Planning Commission Review and Findings:
The Planning Commission shall review the determination and
recommendations of the Traffic Engineer and the Planning
Department, at a duly noticed public hearing, and make one of
the following findings:
1. The City has issued a building or grading permit for the
project prior to May 8, 1978, and that the person to
whom such permit was issued has, in good faith and in
reliance upon such permit, diligently commenced
construction and performed and incurred substantial
liabilities for work and materials necessary therefor.
No change, causing a substantial increase in traffic
volumes, has been made in such project, except in
accordance with the provisions of the Traffic Phasing
Ordinance; or
2. The traffic projected one year after project completion, •
during any a.m. or p.m. 2.5 hour peak traffic period on
each leg of each critical intersection, will be increased
less than 1% by traffic generated from the project during
any a.m. or p.m. 2.5 hour period; or
3. A traffic analysis has been performed and accepted. The
traffic analysis was based on the projected street system
and projected traffic volumes one year after completion
of the project or portion of the project for which the
traffic analysis was performed. The traffic analysis has
shown that at that time, the additional traffic generated
by the project, or portion of the project, including any
approved trip generation reduction measures:
a. will neither cause nor make worse an
unsatisfactory level of traffic service on any
major," "primary modified," or "primary" streets;
or

b. may cause or make worse an unsatisfactory level
of traffic service on one or more "major," "primary
modified," or "primary" streets; or
C. may cause or make worse an unsatisfactory level
of traffic service on one or more "major," "primary
modified," or "primary" streets; however, the
benefits outweigh the anticipated negative impact
on transportation facilities, for the following
reasons: (specify)
E. Approval of Applications:
A simple majority vote by the Planning Commission, subject to
City Council review or appeal, is required for finding D.1, D.2,
D.3.a., or D.3.b. A four -fifths majority vote by the Planning
Commission (or by the City Council on appeal or review) is
required for finding D.3.c.
F. Appeals:
1. The determination of the Planning Commission may be
appealed to the City Council pursuant to the procedure
set forth in Section 20.80.070 of the Newport Beach
Municipal Code.
2. The City Council shall have a Right of Review as set
forth in Section 20.80.075 of the Newport Beach
Municipal Code.
II. Outline of Methodology for Traffic Analyses
A. Designation of Impacted Intersections and Determination of
Project Impact for the a.m. and p.m. 2.5 Hour Peak Periods:
1. The Traffic Engineer will determine which intersections
will be affected by the proposed project according to its
size and geographic location.
2. An analysis will be done whereby it will be determined
if one year after completion of the project, or portions of
the project for which the traffic analysis is being
3

performed, the project (including those portions for
which traffic analyses have been previously approved)
will generate one percent or more of the projected traffic
volumes for each leg of each impacted intersection
during that a.m. and p.m. 2.5 hour peak periods. If less
than a one percent increase is demonstrated for each leg,
then the analysis is concluded, and finding LD.2. may be
made.
B. If the initial Traffic Study indicated the project, or portion of the
project, for which the traffic analysis is being performed, one
year after completion may generate one percent or more of
projected traffic volumes on one or more legs of any impacted
intersection, then the Traffic Engineer or a qualified consultant
will analyze the intersection capacity utilization for the
impacted intersection(s):
The report will indicate the following.
1. Existing traffic. •
2. Projected increases in regional traffic by using the
transportation model and average growth rate for each
roadway over the preceding five (5) years.
3. Projected traffic from committed projects including all
projects within the City and sphere -of- influence
including the Newport Dunes, the Irvine Coastal Area,
Santa Ana Heights, Beeco- Banning property and
additional projects as determined by the Traffic Engineer
which would have significant traffic impacts in the City.
4. Traffic generated by the proposed project, or portion of
the project, without trip generation reduction measures.
5. Traffic generated by the proposed project, or portion of
the project; with approved trip generation reduction
measures.
C. Where a full traffic analysis is performed under Section IIB, the
following I.C.U. calculations shall be performed for each •
impacted intersection:
4
L-18
1. The existing I.C.U.
2. The I.C.U., with traffic system improvements that will be
installed before one year after project completion. This
I.C.U. calculation shall be based on all projected traffic
sources except the proposed project.
3. The I.C.U., with traffic system improvements that will be
installed before one year after project completion, based
on all sources of traffic, including traffic generated by the
proposed project, with approved trip generation
reduction measures.
I.C.U. calculations shall assume a lane capacity value of 1600 vphg for both
through and turn lanes; no factor for yellow time shall be included. I.C.U.
calculations shall be carried to three decimal places and rounded to two decimal
places.
IIL Definitions and Analysis Restraints
A. Traffic System Improvements:
Traffic system improvements may be included in the traffic
analysis for a proposed project, provided that:
1. The improvement will be completed no more than one
year after completion of the project or project phase for
which the traffic analysis is being performed; and
2. The improvement is included in the Circulation Element
of the General Plan, and is defined sufficiently therein to
permit an I.C.U. analysis to be performed; or
3. The improvement design has been approved by the City
Council, and is defined sufficiently to permit an I.C.U.
analysis to be performed.
B. Projected Capacity Increases from Traffic System
Improvements:
For purposes of the traffic analysis, 70% of the incremental
increase in intersection capacity (based on a capacity of 1600
5
Ir18 •
vehicles per hour of green time for each full traffic lane) shall be
utilized. Upon completion of the improvement, traffic volume
counts shall be updated, and any additional available capacity
may then be utilized in future traffic analyses.
C. Traffic Volumes:
1. Traffic volumes shall be based on up- to-date estimates of
traffic volumes expected to exist one year after
completion of the project, or portion of the project, for
which the traffic analysis is being performed. Such
estimates shall include existing traffic as determined by
biennial field counts plus traffic generated by previously
approved projects or portions of projects expected to
exist in the same time period plus estimated increases in
regional traffic.
If the intersection configuration being analyzed is the
ultimate configuration consistent with the Circulation
Element or otherwise approved by the City Council, then •
the traffic volumes used in the analysis shall include total
traffic expected to be generated from all previously
approved projects even if they will not be completed at
the time the subject project is completed.
2. The incremental regional traffic for the time period
between the date of existing counts and one year after
project completion will be estimated based on the rate
projected by the traffic model or on a growth projection
developed by the Traffic Engineer and approved by the
Planning Commission.
3. For making the 1% test of ILA.2., traffic volumes shall
not be used which exceed the capacity of the circulation
system specified in the General Plan.
D. Trip Generation:
1. Trip generation estimates for the project shall be based
on standard trip generation values established by the
City Traffic Engineer. Standard trip generation rates •
may be modified only when the applicant proposes
6
L-18
specific, permanent measures that will reduce peak hour
traffic generated by the project, provided that:
a. The applicant describes in writing, in advance of
the traffic analysis, the proposed measure, the
estimated reduction in trip generation that will
result, and the basis for the estimate. The estimate
must be approved by the Planning Commission or
City Council on appeal or review before the trip
generation figures may be reduced; and
b. The applicant provides the Planning Commission
with a written assurance that the proposed trip
generation reduction measure will be
permanently implemented, and agrees to make
said permanent implementation a condition for
project approval.
2. Credit shall be given for existing uses on the project site
except that no credit shall be given for any use that has
been terminated for more than one year prior to the
filing of an application for new development on the
property.
E. Traffic Distribution:
Traffic distribution shall be based on the traffic network
expected to exist one year after project completion including
those portions of the network associated with previously
approved projects or portions of projects expected to exist at
that time.
F. Improvements or Modifications to the Circulation System:
If the applicant wishes to propose quantifiable improvements or
changes to the circulation system, which may not appear to be
strictly consistent with the Circulation Element, or special
assumptions as a basis for the traffic analysis, he shall provide a
description of such proposals in writing to the Planning
Commission, along with supporting data justifying their use, in
advance of the traffic analysis. Such proposals may then be
7
L-18
used in the Traffic Analysis if they are approved by the
Planning Commission and the City Council.
IV. Issuance of Permits
Permits may be issued for all or a portion of a project after an
appropriate finding under I.D. has been made.
A. Grading Permits:
Grading permits may be issued prior to performance of the
traffic analysis if vesting rights associated with grading are
waived by applicant.
B. Building Permits:
Where traffic system improvements have been included in the
traffic analysis, building permits may be issued only after
traffic system improvement timing has been confirmed as
follows:
1. It has been budgeted and committed for development by
the City; or
2. The State or County or other governmental agency
making the improvement has accepted bids; or
3. The improvement is to be installed or guaranteed by the
applicant in conjunction with the development project
and is approved by the appropriate governmental
jurisdictions.
