ADMINISTRATIVE PROCEDURES FOR IMPLEMENTING
THE TRAFFIC PHASING ORDINANCE
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 # rovisions of the Ordinance,
with the Planning Department. The request must be
accompanied by a projectAescription, 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 according to the methodology
approved by the CitA Council.
C. Staff Recommendation.
1. The City's Traffic Engineer will review the report
prepared by thl consultant and transmit the findings
and worksheet o the Planning Department for
presentation Jo the Planning Commission.
D. Planning Commiss' n Review and Findings:
The Planning Co ission 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 follow g findings:
1. The Cit has issued a building or grading permit for
the pro ect prior to May 8, 1978, and that the person
to whoit such permit was issued has, in good faith and
in reliance upon such permit, diligently commenced
constiuction 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
S -1
Administrative Procedures for Implementing
the Traffic Phasing Ordinance - Page 2
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)

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) w #ll 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.
S -1
Administrative Procedures for Implementing
the Traffic Phasing Ordinance - Page 4
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 byithe 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.0 calculations shall be performed
for each impacted intersection:
1. The existing I.C.U.j
I
2. The I.C.U., with tr *ffic system improvements that will
be installed before one year after project completion.
This I.C.U. calcula ion shall be based on all projected
traffic sources exc4t 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:
f
S -1
Administrative Procedures for Implementing
the Traffic Phasing Ordinance - Page 5
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 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 annual 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.
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.
40
Administrative Procedures for Implementing
S -1
the Traffic Phasing Ordinance - Page 6
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:
j
1. Trip generation estimates for the project shall be
based on standard tip generation values established by
the City Traffic Engineer with the approval of the
Planning Commissionior City Council on appeal or
review. These trip generation figures may be modified
only when the applicant proposed specific, permanent
measures that will rAduce 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.

S -1
the Traffic Phasing Ordinance - Page 7
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:
10 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.
