ADMINISTRATIVE PROCEDURES FOR IMPLEMENTING 2/26/79
THE TRAFFIC PHASING ORDINANCE
I. ADMINISTRATIVE PROCEDURES
A. General:
These procedures apply to all commercial or ind strial projects which
have a gross floor area greater than 10,000 sq ft., and all residen-
tial projects of more than ten dwelling units
B. Evaluating Projects:
1. The applicant files a request for co ideration of the entire project,
under the provisions of the Ordinanc with the Community Develop-
ment Department. The request must a accompanied by a project
description, project phasing sched le, site plan, and fees as set
by the City Council.
2. A traffic analysis shall then
engineer according to the met
C. Staff Recommendation:
prepared by a qualified traffic
logy approved by the City Council.
1. The City's Traffic Enginee will review the report prepared by the
consultant and transmit t e findings and worksheet to the Community
Development Department f r presentation to the Planning Commission.
D. Planning Commission Review nd Findings:
The Planning Commission s all review the determination and recommenda-
tions of the Traffic Eng neer and the Community Development Department,
at a duly- noticed publi hearing, and make one of the following findings:
1. The City has issu a building or grading permit for the project
prior to May 8, 1 78, and that the person to whom such permit was
issued has in go d faith and in reliance upon such permit diligently
commenced const ction and performed and incurred substantial lia-
bilities for wo k and materials necessary therefore. No change
causing a subs antial increase in traffic volumes has been made in
such project, except in accordance with the provisions of the Traffic
Phasing Ordi nee; or
2. The traffic projected one year after project completion during any
2.5 hour p ak traffic period on each leg of each critical inter-
section w. 1 be increased less than 1% by traffic generated from
the proje t during that 2.5 hour period; or
3. A traffic analysis has been performed and accepted. The traffic
analys was based on the projected street system and projected
traff' volumes one year after completion of the project or portion
of t project for which the traffic analysis was performed. The
traf is analysis has shown that, at that time, the additional traffic
gen rated by the project, or portion of the project, including
an approved trip generation reduction measures:

c. may cause or make worse an unsatisfactory level of traffic ser-
vice on one or more "major ", "primary- modified ", or "primary"
streets; however, the benefits outweigh the anticipated nega-
tive 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 2.5 Hour Peak Period:
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 2.5
hour peak period. 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):
a. will neither cause nor make worse an unsatisfactory level of
traffic service on any major ", "primary- modified ", or "primary'
street; 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 ser-
vice on one or more "major ", "primary- modified ", or "primary"
streets; however, the benefits outweigh the anticipated nega-
tive 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

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. This I.C.U. must be
0.90 or less to make finding I.D.3.a.
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:
1. The improvement will be completed no more than one year after com-
pletion 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
The report will indicate the following:
1. Existing traffic.
2. Projected increases in regional traffic.
3. Projected traffic from committed projects that will be completed
before one year after the completion date of the project or portion
of the project for which the traffic analysis is being performed.

ADMINISTRATIVE PROCEDURES FOR IMPLEMENTING THE TRAFFIC PHASING ORDINANCE - Page 4 S -1
2/26/79
For purposes of the traffic analysis, 70% 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.
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 deter-
mined by annual 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 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 with
the approval of the Planning Commission or City Council on appeal or
review. These trip generation figures may be modified only when the
applicant proposes specific, permanent measures that will reduce traffic
generated by the project, provided that:
1. 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.
2. 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.

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 consis-
tent with the Circulation Element, or special assumptions as a basis
for the traffic analysis, he shall provide a description of such pro-
posals 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 analy-
sis 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:
I. It has been budgeted and committed for development by the City; or
2. The State or County or other governmental agency making the improve-
ment 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.
