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
subsequest 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.
B. Evaluating Projects:
1. The applicant files a request or consideration of the
entire project, under the pr isions of the Ordinance,
with the Planning Department: The request must be
accompanied by a project dq cription, project phasing
schedule, site plan, and es as set by the City
Council.
2. A traffic analysis shai then be prepared by a
qualified traffic engtheer under contract to the City
according to the methodology approved by the City Council.
3. The traffic analysO; 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 mote 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

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 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.
C. Where a full traffic analysis is performed under Section
IIB, the following I.C.U. calculations shall be performed
for each impacted intersection:
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.

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.
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.
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:
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 existin uses on the projectg
site except that no credit shall e 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.
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.

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.
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

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.
