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: ADMINISTRATIVE PROCEDURES FOR IMPLEMENTING THE TRAFFIC PHASING ORDINANCE - Page 2 S -1 2/26/79 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 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.

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): ADMINISTRATIVE PROCEDURES FOR IMPLEMENTING THE TRAFFIC PHASING ORDINANCE - Page 3 S -1 2/26/79 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. 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. 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 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. y ADMINISTRATIVE PROCEDURES FOR IMPLEMENTING THE TRAFFIC PHASING ORDINANCE - Page 5 S -1 2/26/79 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.
