THE TRAFFIC PHASING ORDINANCE
S -1
I. ADMINISTRATIVE PROCEDURES
A. General:
These procedures apply to all commercial or industrial
projects which have a gross floor area greater than 10,000
sq.ft., or with an Average Daily Trip generator of more than
130 daily trips; and all residential projects of more than
ten dwelling units.
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
The traffic projected one year after pro ect
completion, during any a.m. or p.m. 2.5 our peak
traffic period on each leg of each critical
intersection, will be increased less than 18 by
traffic generated from the project during any a.m. or
p.m. 2.5 hour period; or
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:
will neither cause nor make worse an
unsatisfactory level of traffic service on any
major," "primary- modified," or "primary"
streets: or
may cause or make worse an unsatisfactory level •
of traffic service on one or more "major,"
primary- modified," or "primary" streets; or
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)
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.
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.
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 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 I.D.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.
Where a full traffic analysis is performed under Section
IIB, the following I.C.U. calculations shall be performed
for each impacted intersection:
The existing I.C.U.

Administrative Procedures for Implementing
the Traffic Phasing Ordinance - Page 4
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.
III. DEFINITIONS AND ANALYSIS RESTRAINTS
A. Traffic System Improvements:
Traffic system improvements may be included in the traffic
analysis for a proposed project, provided that:
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 •
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
The improvement design has been approved by the City
Council, and is defined sufficiently to permit an
I.C.U. analysis to be performed.
Projected Capacity Increases from Traffic System
Improvements:
For purposes of the traffic analysis, 708 of the incremental
increase in intersection capacity (based on a capacity of
1600 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.
Traffic Volumes:
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 gen-
erated by previously approved projects or portions of •
projects expected to exist in the same time period
plus estimated increases in regional traffic.
Administrative Procedures for Implementin¢

the Traffic Phasing Ordinance - Page 5
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 II.A.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 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.
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 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.
