Figure 1 titled "Vicinity Map" shows the project location. 1 Figure 2 titled "Site Plan" shows the layout of the project known as the "Newport Sea Crest Apartments. " As is indicated on Figure 2 , the existing project will replace four existing single family dwelling units. 1 This analysis has been conducted in accordance with the City of Newport Beach traffic phasing analysis method- ology. 1 1 i i 1 i 1 1 � 1 1 '� 1 y�c• � 2 v �t NO 5644E /5fh 5T /S"S p RM05PEC7-sr.

' Table 1 indicates that the net total 24 hour volume generated by the project will be 370 vehicles. This table also shows the projected p.m. peak hour generation, as well as the 2-1/2 hour p.m. peak generation totals. ' The traffic generation rates utilized in Table 1 were obtained from the City Traffic Engineer. TABLE 1 Trip Generation T r i p R a t e T r i p E n d s ' No. P.M. P.M. P.M.

Figure 3 titled "Trip Distribution and Assignment" shows that it is estimated that 70 percent of the generated traffic will be oriented northerly while 10 percent will be oriented westerly and 20 percent easterly. Figure 3 also shows, using these percentage distributions, the specific project trip assignments for the 2-1/2 hour p.m. peak at the six intersections that were selected by the City Traffic Engineer to be included in the analysis. These specific intersections are as follows: ' o Placentia Avenue/Superior Avenue o Coast Highway/Balboa Boulevard-Superior Avenue o Coast Highway/Prospect Street ' o Coast Highway/Orange Street o Coast Highway/Riverside Avenue o Coast Highway at Dover Drive/Bayshore Drive ' 5 70 � w ° N05C4LE /5fh 57 �z PR0.5PE0r sr.

' COMPLETED PROJECT TRAFFIC ' The City Traffic Engineer furnished a listing of other projects in the City that would be completed by 1987, the year of completion of the proposed project. Volumes for each of the six intersections listed above are provided in Appendix A. t II 1 1 ' 7 1 ' ONE PERCENT ANALYSIS ' Based on the estimated traffic generation from the pro- ject, existing traffic volumes at the six study intersec- tions, projected regional traffic growth along Coast ' Highway of 2 . 3 percent per year compounded and the p.m. peak traffic volumes from the completed projects, the one percent traffic volume analysis worksheets were completed. ' The completed one percent traffic volume analysis data sheets are shown in Appendix B. ' It was found that for all six of the study intersections the project traffic is estimated to be less than one percent of projected peak 2-1/2 hour traffic volume. ' Because the project traffic did not exceed the one percent criteria, an ICU analysis will not be needed for the project traffic analysis. 1 8 ' APPENDIX A ' Approved Project Traffic Volumes 1 t RPT NR: TE510 TRAFFIC PHASING ORDINANCE PAGE: 04 DATE: 04/17/85 REPORT ON APPROVED PROJECT VOLUMES SUMMARY INTERSECTION-NAME TNT-NR SUPERIOR AV / PLACENTIA AV 2565 2-1/2 HR-PM-PEAK 1-HOUR PM-PEAK YR NB SB EB 'aB NL NT NR SL ST SR EL ET ER 'aL YT 4R 97 151 50 L20 151 0 26 53 2 17 12 5 59 0 47 49 3 2-1/2 HR-AM-PEAK 1-HOUR AM-PEAK NB SB EB 4B NL NT NR SL ST SR EL ET ER wL YT UR 0 0 0 0 0 0 0 0 0 0 0 0 O 0 0 D 1 1 1 m m m m i m m � � � m m m HPT NR: TE510 TRAFFIC PHASING ORDINANCE PAGE: 02 DATE: 04/17/35 REPORT ON APPROVED PROJECT VOLUMES SUMMARY I4TERSECTION-NAME INT-NH COAST HWY / BALBOA BL - SUPEPIOF AV 1855 2-1/2 HR-PM-PEAK 1-HOUR PM-PEAK YR NH SB EB W8 NL NT NR SL ST SR EL ET ER WL WT WR 87 54 172 765 811 17 16 0 17 17 56 42 340 12 0 391 12 2-1/2 HR-AM-PEAK 1-HOUR AM-PEAK NB SB ES WB NL NT NR SL ST SR EL ET ER aL WT WR D 0 0 0 0 0 0 0 0 0 0 0 G 0 0 0 1 m m m m r ; m m m r m m m m m m m m m ROT NR: TE510 TRAFFIC PHASING ORDINANCE PAGE: 02 DATE: 04/17/85 REPORT ON APPROVED PROJECT VOLUMES SUMMARY INTERSECTION-NAME INT-NR COAST HWY / PROSPECT ST 2260 2-1/2 HR-PM-PEAK 1-HOUR PM-PEAK YR VB SB EB WB NL NT NR SL ST SR EL-- ET ER WL WT mR BT 0 0 647 1010 a 0 0 0 0 0 0 335 0 0 502 a 2-1/2 HR-AM-PEAK I-HOUR AM-PEAK Na SO EB WB NL NT NR SL ST SR £L ET ER WL WT WR 0 o D 0 o D o D o 0 a 0 0 0 0 0 m m r m .� m m � m m m = m m m m m � ROT NR: TE510 TRAFFIC PHASING ORDINANCE PAGE: 02 GATE: 04/17/35 REPORT ON APPROVED PROJECT VOLUMES SUMMARY INTERSECTION-NAHE INT-NR COAST HJY / ORANGE ST .2285 2-1/2 HR-PM-PEAK 1-HOUR PM-PEAK YR IN SB EB Na NL NT NR SL ST SR EL ET ER NL 4T 4R 97 a a 647 1010 0 a 0 a 0 0 0 335 ❑ D S❑l 1 2-1/2 HR-AM-PEAK 1-HOUR AM-PEAK NB SB E8 V8 NL NT NR St. ST SR EL ET ER VL 4T YR a 0 0 ❑ 0 0 0 G 0 0 0 0 0 0 0 0 L RPT NR: TESIO TRAFFIC PHASING ORDINANCE PAGE: 02 DATE: 04/17/35 REPORT ON APPROVEO PROJECT VOLUMES SUMMARY INTERSECTION-NAME INT-NR COAST HWY / RIVERSIDE AV 2630 2-1/2 HR-PM-PEAK 1-HOUR PM-PEAK YR VB S8 EB WB NL NT NR SL ST SR EL ET ER WL W7 WR 87 0 33 1047 1012 0 0 0 5 0 11 12 507 0 0 511 3 2-1/2 HR-AM-PEAK 1-HOUR AM-PEAK 148 SB EB WB NL NT NR SL ST SR EL ET ER WL WT WR 0 0 a 0 0 a 0 a 0 0 0 0 a 0 0 O 1 1 40T NR: TE510 TRAFFIC PHASING ORDINANCE PAGE: 02 DATE: 04/17/85 REPORT ON APPROVED PROJECT VOLUMES SUMMARY INTERSECTION-NAME INT-NR COAST HAY / DOVER OR - BAYSHORE OR 3060 2-1/2 HR-PM-PEAK 1-HOUR PM-PEAK YR NB SB EB 118 NL NT NR SL ST SR EL ET ER WL WT 4R 87 7 95 1037 1014 1 0 6 24 0 17 18 493 2 0 478 37 2-1/2 HR-AM-PEAK 1-HOUR AM-PEAK NB SB ES NB NL NT NR SL ST SR EL ET ER KL KT {,R a D a a 0 a D D D 0 a 0 a 0 a 0 r i ' APPENDIX B One Percent Analysis Data Sheets ' 1% Traffic Volume Analysis Intersection Placentia Ave./Superior Ave. (Existing Traffic Volumes based on verage 'inter Spring 1983 Peak 2� Hour Approved ' Approach Existing Regional Projects Projected 1% of Projected Project Direction Peak 2; Hour Growth Peak 2; Hour Peak 2.11 Hour Peak 21i Hour Peak 2� Hou Volume Volume Volume Volume Volume Volume Northbound 957 /049 /5l /ZDO 1E 9 southbound 1425 /SbZ •s A� (o Eastbound 1496 /bgD /20 17( O /$ S Westbound 1479 /SI 77Z lg D Project Traffic is estimated to be less than 1% of Projected Peak 22 Hour Traffic Volume ' a Project Traffic is estimated to be greater than 1% of Projected Peak 22 Hour Traffic Volume.
