IINTRODUCTION The purpose of this study is to assess the traffic-related impacts of proposed commercial office/retail development on the site located at 2912 West Coast Highway in Newport Beach. The study will address the existing traffic conditions in the area surrounding the proposed project, including the eleven critical intersections identified by the City Traffic Engineer. It will provide an estimate of trip generation and distribution for the proposed development, as well as identify the potential traffic impacts of the project in the context of conditions including other committed develop- ment in the area. The study is intended to satisfy the requirements of the Traffic Phasing Ordinance of the City of Newport Beach and includes the necessary analyses of peak-period and peak hour traffic flow conditions at critical intersections. On-site circulation and parking provisions will be evaluated as well as the adequacy of site access._ i I PROJECT DESCRIPTION The proposed project site is located along the north side of West Coast Highway, west of Riverside Avenue, in the area known as Mariners' Mile. Figure 1 shows the location of the proposed project. Proposed development would consist of approximately 6,750 square feet of retail space and 9.200 square feet of office space. Parking would be provided (65 spaces) on the rear portion of the site. Access to/from the project would be along Avon Street. Figure 2 is the proposed project site plan. With the development of the proposed project. an existing 2.050 square foot restaurant and 460 square foot electronics store would be eliminated. EXISTING CONDITIONS Existing land uses surrounding the project site include marine-related uses, retail uses. restaurants and commercial office space. ROADWAY CHARACTERISTICS Arterials immediately surrounding and serving the project site include 1 West Coast Highway. Avon Street and Riverside Avenue. To a lesser degree. project traffic would be expected to use Newport Boulevard. Tustin Avenue and Dover Drive. The following provides a brief description of the three arterials surrounding and serving the project. l _ - 1 - y . DKS Associates ! 55 J 4 p�P 'J• �.

OOO ➢N� �J[' c.0 5 TR 0`)v _4V Figure 2 SITE PLAN r l Coast Highway (State Route 1) parallels the coastline throughout the City of Newport Beach. It connects Newport Beach with the coastal cities of Huntington Beach, Seal Beach and Long Beach to the north and Laguna Beach, South Laguna and Dana Point to the south. It serves as an alternative travel route to the I-405 Freeway between the south County and the Irvine/- Newport Beach/John Wayne Airport areas during congested peak hours. Within Newport Beach. it is one of two routes (the other being the Bristol Couplet) around Newport Bay. Because of this, it serves a significant amount of "around the Bay" travel between the eastern and western sections of the City. In the vicinity of the proposed project. Coast Highway consists of three westbound travel lanes and two eastbound travel lanes. Based on traffic count data collected in 1986. Coast Highway in the vicinity of the proposed project carries approximately 54.000 vehicles per day. During peak summer months. the volume of traffic increases to approximately 54,000 vehicles per day. + Riverside Avenue, immediately north of Coast Highway, has two lanes in each direction. North of Avon Street. Riverside Avenue becomes a two-lane roadway, serving the residential areas of Newport Heights. Avon Street is presently a local roadway extending west of Riverside Avenue and east of Riverside to Tustin Avenue. At the present time. it serves as secondary access to development along Riverside Avenue. Most importantly, it provides access to the Post office customers and service/delivery vehicles. EXISTING PEAK HOUR CONDITIONS Analysis of peak hourly traffic operating conditions at critical Intersec- tions provides an indication of traffic flow and locations of potential congestion in the area surrounding the proposed project. Eleven critical intersections in the vicinity of the proposed project have been identified for analysis by the City's Traffic Engineer. Intersection Capacity Utilization (ICU) analyses have been performed for the morning peak hour and the evening peak hour at each of these inter- sections. The data used in these analyses represent conditions as of Winter/Spring 1987. Table 1 summarizes the results of these analyses. Review of Table 1 shows that all of the intersections within the vicinity of the proposed project are operating acceptably. with ICU values of 0.90 or better during peak hours, except the intersection of Coast Highway at Superior Avenue/Balboa Boulevard. During the morning peak hour. this intersection presently operates with an ICU ratio of 0.98. Copies of the 1 ICU worksheets are included in Appendix A of this report. t - - 3 - f ITABLE 1 SUMMARY Of EXISTING (1987) INTERSECTION CAPACITY UTILIZATION ANALYSES Existing Conditions ICU j Critical intersection AM Peak Hour PM Peak hour i Coast Highway at: Orange Street 0.57 0.85 Prospect Street 0.60 0.89 Balboa Boulevard/ Superior Avenue 0.98* 0.86 Riverside Avenue 0.76 0.76 Tustin Avenue 0.78 0.63 Dover Drive/ Bayshore Drive 0.65 0.76 Bayside Drive 0.79 0.90 f Newport Boulevard at: i Via Lido 0.73 0.73 Hospital Road 0.55 0.76 I *Indicates that existing operating conditions are less than satisfactory, defined as a ICU greater than 0.90. l 1 i ESTIMATED PROJECT TRAFFIC TRIP GENERATION To assess the impacts of the proposed development on the surrounding cir- culation system, tripmaking to/from the proposed project has been estimated. Table 2 shows the trip generation rates approved by the City of Newport Beach for estimating project tripmaking. These rates have been applied to the quantities of land use proposed for the project and the resulting estimate of tripmaking attributable to the proposed project is presented in Table 2. It has been assumed that approximately 15 percent of the estimated travel demand attributable to the project could be satisfied within the site. It would be expected that the businesses and their employees in the project office space would utilize the on-site retail . The retail space could include office supplies. services such as copying or printing, or snacks and sundries. The project is estimated to generate approximately 390 average daily trips. Approximately 30 trips are estimated to occur during the morning peak hour and 44 during the evening peak hour. Of these, approximately 331 average daily trips would be external to the project site. with approximately 26 occurring during the morning peak hour and 38 occurring during the evening peak hour. Existing uses which would be eliminated with the development of the proposed project include a 2.050 square foot restaurant and a 460 square foot elec- tronics store. To determine the increase in traffic which could be expected to occur with the proposed uses, estimated trip-making for the existing uses which will be eliminated must be subtracted from estimated trip-making for the proposed uses. Table 3 summarizes estimated trip-making for the existing uses and the net increase in traffic which would be expected with the proposed uses. Review of Table 3 shows that the project is expected to add approximately surrounding roadway system. trips to the 9 159 additional average daily p Approximately 22 trips (18 inbound. 4 outbound) are estimated to occur during the morning peak hour and 20 trips (2 inbound, 18 outbound) are estimated to occur during the evening peak hour. TRIP DISTRIBUTION The trip distribution characteristics for the proposed project and for the existing uses were estimated based on distribution assumptions contained in previous studies for the site and surrounding sites, and on conversations ! - - 5 - 1 TABLE 2 SUMMARY OF TRIP GENERATION CHARACTERISTICS Trip Generation Rates AM Pk 2-/12 Hr AM Peak Hour PM Pk 2-1/2 Hr PM Peak Hour L..nd Use Units Daily In Out In Out In Out In Out Retail (General ) 1.000 SF 40.0 1.4 1.0 0.7 0.5 3.0 4.0 1.5 2.0 Office 1.000 SF 13.0 4.0 0.8 2.0 0.4 1.2 3.4 0.6 1.7 Estimated Trip Generation AM Pk 2-/12 Hr AM Peak Hour PM Pk 2-1/2 Hr PM Peak Hour Land Use Units Daily In Out In Out In Out In Out Retail (General ) 6.750 SF 270 9 7 5 3 20 27 10 13 Office 9.200 SF 120 37 7 18 4 11 31 5 16 Subtotal 390 46 14 23 7 31 58 15 29 Less-15% Internal Trip-making 58 7 2 3 1 5 9 3 4 331 39 12 20 6 26 49 13 25 TABLE 3 SUMMARY OF TRIP GENERATION CHARACTERISTICS Trip Generation Rates AM Pk 2-/12 Hr AM Peak Hour PM Pk 2-1/2 fir PM Peak Hour Land Use Units Daily In Out In Out In Out In Out Restaurant 1.000 SF 75.0 2.0 v`'�O 1.0 0.5 10.0 6.0 5.0 3.0 Retail (General ) 1.000 SF 40.0 1.4 1.0 . 0.7 0.5 3.0 4.0 1.5 2.0 Estimated Trip Generation AM Pk 2-/12 Hr AM Peak Hour PM Pk 2-1/2 fir PM Peak Hour Land Use Units Daily In Out In Out In Out In Out Restaurant 2.050 SF 154 4 2 1 1 21 12 10 6 Retail (General ) 460 SF 18 1 Nom Nom Nom 1 2 1 1 Subtotal 172 5 2 2 2 22 14 11 7 Proposed Project 331 39 12 20 6 26 49 13 25 Existing Uses 172 5 2 2 2 22 14 11 7 Net Increase With Proposed Project 159 34 10 18 4 4 35 2 18 with the City' s Traffic Engineer. The most significant feature of the project affecting trip distribution is the inability to provide direct access to/from Coast Highway. Vehicles must enter/exit the site from Avon Street. Figure 3 shows the trip distribution to/from the project site. In general . approximately 48 percent of the project traffic is estimated to be oriented to/from the west along Coast Highway and approximately 38 percent is oriented to/from the east. This is consistent with the assump- tions used in the Mariners' Mile Specific Plan Traffic Study and in the previous study for this project site. The additional trips estimated to be generated by the proposed project have been distributed to the surrounding roadway system based on the trip distribution patterns depicted in Figure 3. Figure 4 shows the resulting project-related peak hour traffic volumes along roadways in the vicinity of the proposed project. TRAFFIC IMPACT ANALYSIS Under the City of Newport Beach Traffic Phasing Ordinance. project traffic impacts are estimated and evaluated for morning and evening peak conditions at critical signalized intersections within the City, as identified by the i City's Traffic Engineer. If estimated project traffic for the morning peak 2 1/2 hour period or the evening peak 2 1/2 hour period at an inter- section is greater than 1 percent of the existing condition traffic volume. plus regional growth, plus estimated traffic for projects which have been approved but not yet constructed, an Intersection Capacity Utilization (ICU) analysis is performed. If the additional increment of traffic attri- butable to the proposed project results in or makes worse an ICU value i greater than 0.90. further analysis is required to develop specific miti- gation measures. y As discussed previously, the City's Traffic Engineer has identified 11 J critical intersections within the City which might be impacted by the proposed project. Project impacts at each of these intersections have been estimated and evaluated for 1990 conditions, as defined by the City's Traffic Engineer. This would represent traffic flow conditions approxi- mately one year after completion of the proposed project. APPROVED PROJECTS To develop estimates of traffic for 1990. the City provides estimates of traffic to/from projects which have been approved for future construction but are not yet completed, occupied and generating traffic. This additional traffic is to be added to existing traffic volumes and regional growth to obtain an estimate of cumulative traffic for a desired timeframe.

REGIONAL GROWTH The City has developed estimates of the annual rate of growth along region- ally significant arterials within the City. This is because traffic volumes along these roadways would be expected to increase not only as a result of additional approved development within the City. but also due to additional growth and development in the surrounding region. Within the study area of the proposed project. the following annual growth rates were applied to the existing volume at critical intersections: Coast Highway: IJamboree Road to Newport Boulevard 1% Newport Boulevard to West City limits 2.5% Newport Boulevard: Coast Highway to North City Limits 1% ONE PERCENT ANALYSIS The estimated morning peak 2 1/2 hour traffic volume and evening peak 2 1/2 hour traffic volume to/from the proposed project have been compared to the base volume (existing traffic plus regional growth plus approved projects' traffic) for 1990 conditions at each of the critical inters- ections. The estimated peak 2-1/2 hour project volume was greater than 1 percent of the base- volume at only one intersection: Coast Highway at Riverside Avenue. Therefore. ICU analyses have been performed for 1990 conditions at this intersection. Table 5 summarizes the results of this analysis. The One Percent Analysis worksheets are included in Appendix B of this report. INTERSECTION CAPACITY UTILIZATION ANALYSIS Table 6 is a summary of the ICU values estimated at the intersection of Coast Highway and Riverside Avenue for existing conditions. 1990 base condi- tions (existing traffic plus regional growth plus estimated approved pro- jects' traffic). and 1990 conditions plus the proposed project. - 12 - i TABLE 5 I SUMMARY Of 1 PERCENT ANALYSIS i Does Project Traffic Constitute Less Than 1% of Peak 2.5 Hour Volume?

The proposed project has no effect on the ICU values at this intersection. The morning and evening peak hour ICU values are estimated to remain at 0.95 with the additional increment of traffic to/from the proposed project. ' SITE ACCESS. INTERNAL CIRCULATION AND PARKING SITE ACCESS As discussed previously and depicted in Figure 2. project access is to be provided along Avon Street. The access is adequate to accommodate the level of tripmaking estimated for the proposed project. The dominant demand will be outbound during the evening peak hour, at which time approximately 25 vehicles are estimated to exit the site. Since the movement of vehicles from the site will be made by right turns from the access drive (Avon Street does not presently extend west of the project). the estimated exiting traffic can be easily accommodated by one outbound lane. INTERNAL CIRCULATION Traffic circulation within-the project site is limited to ingress/egress of the parking area. A 25-foot wide driveway along Avon Street provides access to/from the parking area. Parking Based on the City' s Zoning Code, the uses proposed for the site would require parking space be provided at a rate of 1 stall per 250 square feet of gross floor area. This equates to a requirement of 64 on site parking stalls. As proposed, the project would provide 65 parking stalls in an at-grade parking area. Sixteen parking stalls, or approximately 25 percent of the parking supply, are to be compact car stalls. This is consistent with the City's parking standards. i - - 15 - 1 SUMMARY o The proposed project is to consist of approximately 6,750 square feet of retail space and 9,200 square feet of office space. Parking is to be provided (65 stalls) on a surface lot at the rear of the site, and in an amount consistent with the requirements of the City's Zoning Code. Access to/from the project is along Avon Street. o The project is estimated to generate approximately 390 average daily trips. Approximately 30 trips are estimated to occur during the morning peak hour and 44 trips are estimated to occur during the evening peak hour. It is estimated that approximately 15 percent of the estimated travel demand for the proposed project would be satisfied on-site due to the mix of office and retail opportunities proposed for the site. ! These trips, which remain internal to the site, would therefore not impact the surrounding roadways. Also, there are presently uses on the site which have been estimated to generate approximately 172 average daily trips (4 during the morning peak hour, 18 during the evening peak hour). and which will be eliminated to accommodate the proposed project. Therefore. the net increase in trips which is estimated to be added to the surrounding roadways with the proposed project is 159 average daily trips (22 during the morning peak hour and 20 during the peak hour). o The 1 Percent Analysis was performed for the eleven critical inter- sections in the vicinity of the project, as identified by the City' s Traffic Engineer. Project traffic is estimated to exceed i percent of the base traffic volume (existing traffic plus regional growth plus approved projects traffic) only at the intersection of Coast Highway at Riverside Avenue. o Intersection Capacity Utilization analysis performed for this inter- section indicates that with existing traffic plus regional growth and approved projects' traffic. this intersection will operate with an ICU i ratio of 0.95 during both the morning and the evening peak hour. The addition of project traffic has no impact on ICU values at this inter- section. o The proposed access along Avon Street would be adequate to accommodate estimated project traffic.
