INTRODUCTION ' This Initial Study has been prepared in accordance with the California Environmental Quality Act (CEQA), the State Guidelines for Implementing CEQA, and the City of Newport Beach Policy K3. The study' s purpose is to enable the City of Newport Beach to determine whether development of a proposed multi-story medical office building will result in a significant ' effect on the environment. The proposed development is a seven-story, 80,000 gross square-foot medical office building and related parking structure located in Block 400 of Newport Center, in Newport Beach. The discretionary actions currently being requested for the project include: - A change in zoning to reclassify Block 400 from C-O-H to Planned Community;) ' - A resubdivision; - A use permit; - A grading permit; and - A building permit. Prior to the approval of the requested zone change, the project applicant is required to obtain the necessary Traffic Phasing Ordinance (TPO) appro- val for the project from the City's Transportation Engineering Department. This requirement was met in September 1983 and is disucssed in detail in Section III.G. of the Initial Study. ' The aforementioned discretionary actions are being requested subsequent to General Plan Amendment (GPA) 81-2 (approved May 1983) which amended the City's Land Use Element to allow 80,000 square feet of office use to be added to the project site. The environmental impact report (EIR) prepared for GPA 81-2 addressed the environmental effects associated With the proposed 80,000 square foot development.2 The EIR was prepared pursuant 1 At the request of the City for administrative purposes, the proposed zone change includes all of the Block 400. The proposed development will only affect a portion of Block 400, and no additional development or changes are proposed for the remainder. of Block 400. 2 The EIR for GPA 81-2 is available for public review at the City of Newport Beach, City Hall-Planning Department, 3300 Newport Boulevard, Newport Beach, CA. 92660. 1 r � to Section 15069.8(a) of the CEQA Guidelines, allowing for the preparation ' of a Program EIR on a series of discretionary approvals which are related as logical parts in a chain of contemplated actions. The Program EIR eval- uates the impacts associated with ultimate implementation of the proposed development. At each discretionary level of project review, the specific activity (Zone Change, Use Permit, etc.) is examined in light of the Pro- gram EIR to determine the need for additional environmental analysis. Such , use of a Program EIR is in accordance with the provisions of CEQA and is encouraged by the State to avoid duplicative evaluation of 'basic policy considerations. The EIR for GPA 81-2 addressed the environmental impacts associated with the proposed development, based upon the most definitive project data available at that time. This Initial Study focusses upon those environ- mental issues for which additional project data has become available.. In the discussion of specific environmental issues which follows in Section III - EXISTING CONDITIONS, IMPACTS AND MITIGATION MEASURES, the reader is , referred to the Certified Final EIR for a detailed discussion of those environmental issues not affected by the additional project data. In the case where specific analyses in the EIR can be augmented by the additional data, a complete discussion of the relevant subject is provided. Since the preparation of the EIR for GPA 81-2, a number of new developments have been proposed W the vicinity of Newport Center. These developments will proportionately add to the cumulative impacts identified in Section 8.0 of the EIR for GPA 81-2. The proposed developments include the following: Project Type # Units or Sq. Ft. r PCH Frontage Residential 151 Dwelling Units Four Seasons Hotel Hotel 325 Rooms Edwards Cinema Expansion Theater �650 Seats Carver Office Business Office 17,000 square feet Auer Office Business Office 23,000 square feet Newport Village Residential 428 Dwelling Units (Max)1 1 The General Plan Amendment for the project allows for 'up to a maximum of 428 d.u. 2 r i II. PROJECT DESCRIPTION ' A. PROJECT LOCATION The 16-acre Block 400 study area is located in Newport Center. Block 400 is bounded on the north by San Nicholas Drive, on the east by Avocado Avenue, on the west by Newport Center Drive and the south by San Miguel rDrive. Fashion Island is west of Block 400 across Newport Center Drive and the Edwards Newport Cinema is across San Miguel Drive to the south. (See Exhibits 1 and 2.) B. PROJECT HISTORY In 1981, Newport Center Medical Buildings, Inc. (NCMB) proposed to con- struct the subject 80,000-square foot, seven-story medical office buiding in Block 400 of Newport Center. City staff informed the applicant that GPA 78-2 had established development limits for Newport Center, at which the amount of existing development within Block 400, approximately 353,600 square feet of medical and general office uses, was the maximum allowable development for the subject property. In 1983, GPA 81-2 amended the City's Land Use Element to permit an additional 80,000 square feet of development in Newport Center. The specific provisions of GPA 81-2 relative to Block, 400 include the following: r1. Allow the addition of 80,000 square feet of medical office development rin Newport Center, along with related parking facilities. 2. Specify this additional allowable development to Block 400, on the parcel located at 400 Newport Center Drive East. r3. The property shall be rezoned to the P-C (Planned Community) District. r4. Specify the development be subject to further review and approval of a ■ use permit. 5. At the time of future discretionary actions the project shall be required to contribute a sum equal to their fair share of future cir- 3 r 1 i ' \ SANN FERNAN00 OASRIEL �i18 I 210 MOUNTAINS I P ' -- I GLENDALE PASADENA ' �101 101 104 �IS4��410 HOLLYWOOD � n p 6 o p 10 ..... 101 10 f0 MOUNTAINS � ^ POMONA/ pP 10 80 MALIBU SANTA MONICA LOS �J 1 ANGELES e0 % P, WHIMER 4 PACIFIC OCEAN 81- 91 St \ r , REOON00 BEACH TORRANCE •pP LAKEWOOD / P ANAHEIM \ 1 LO 22 9ANTA ANA ORANGE COUNTY\'NG ' BEACH SEA EACH 408 bb ' SiVINE r P NEWPORT BEACH PROJECT SITE LAGUNA BEACH r� DANA POINT — SAN CLEMENTE i r Regional Location r BLOCK 400 - MEDICAL OFFICE • • CITY OF NEWPORT BEACH EXHIBIT 1 Ir \ �o C � 9P NEWPORT \ N � 1DA ` w m PROJECT SST ct c /R!//NE G"OAST a`11 �n Y� T,.�� R ry .• ' ccnw,v__� c y\ h m�`�� � `••i PEA Jdad m .rqT� `' S I°• Ito _ I�j � m 'bLAZA .P9ok' � �-�::�'ra-� •.•; p D 4/UQpSCO no �y_ �n�Q.U•c } 1 1 ' Site.

The Block 400 study area currently contains four multi-story office build- ings (ranging from six- to nine-stories), three of which house medical offices and one containing business offices. The proposed project will be , situated adjacent to San Miguel Drive, between the existing seven-story medical office building located at the southwest corner of Block 400 and the nine-story medical office building at the southeast corner. Exhibit 3 ' presents the site plan for the proposed project, while Exhibit 4 shows a section view of the project. , The area proposed for development is part of the large parking lot which , comprises the central portion of Block 400. Much of the southern half of the parking lot lies at an elevation approximately ten feet lower than the northern half. A concrete retaining wall , which increases in height from , east to west, defines the boundary of this grade separation. The project proposal includes a two-story parking structure which will abut the exist- ing retaining wall . The parking structure will extend south approximately 120 feet from the retaining wall , with the upper deck level located 11 feet above grade. Access onto the upper parking deck will be provided from the north as the elevation of the adjacent property. is close to that , 5 ' n -,C o .. i � Sri 1 - \• SITE PLAN.

Parking on the deck level will be restricted to employee use only and will be controlled through an assigned parking space ' program developed by the project sponsor. The lower parking level will include entrances from the south and will be utilized for visitor parking. The location and design of the proposed parking structure eliminates the need for ramps typically associated with ' such parking structures. The total parking provided within Block 400 upon completion of the proposed project will be 1,247 parking spaces, which equals 3.54 parking spaces per 1,000 square feet of gross building area. The parking deck level plan is presented in Exhibit 5. The proposed seven-story office building will be constructed directly south of the parking structure. The architectural design of the proposed office building is very similar to that of the two existing medical office build- ings located in the eastern portion of Block 400. Exhibit 6 presents the north and east elevations for the project, while Exhibits 7 and 8 delineate the ground and typical floor plans. ' The length of the building will extend along a north-south axis thus maximizing southerly views towards the ocean. Exhibit 9 provides an ' oblique aerial view of Block 400 on which a rendering of the proposed project has been plotted. The spatial relationship between the proposed project and nearby existing buildings can be noted within the exhibit. ' Also apparent in Exhibit 9 is the similarity of the proposed office building to the office buildings located to the east. If the requested actions are approved, construction of the proposed project is anticipated to begin in the Spring of 1984.

EXISTING CONDITIONS, IMPACTS, CITY POLICIES AND REQUIREMENTS, AND MITIGATION MEASURES 1 A. LANDFORM/GEOLOGY 1 A detailed discussion of issues pertaining to landform and geology is con- tained in the GPA 81-2 EIR. The following provides a summary of the EIR 1 analysis. 1 Existing Conditions 1 The Block 400 study area is flat and contains four high-rise office build- ings, parking areas, and access drives. 1 The study area is underlain by sandstone and clayey siltstone bedrock with 1 a thin mantle of topsoils and compacted fill . The Pelican Hill fault is located approximately 4,500 feet to the east of 1 the site. Major fault zones of significance within the region include the Newport-Inglewood, Elsinore, San Jacinto and San Andreas systems. 1 No significant landslide or erosion hazards are presented within the study 1 area. 1 Impacts Grading activity will be confined to excavation within the existing paved 1 areas over which the new development will be constructed. A bearing wall for the parking structure will be constructed approximately 2" apart from 1 the retaining wall , thus not affecting the structural integrity of the retaining wall . The project site will be subject to the regional groundshaking hazards posed by major active faults in southern California. 1 No significant geotechnical constraints are anticipated. City Policies and Requirements ' A. An erosion, siltation, and dust control- plan shall, •be prepared by a civil engineer, and based on recommendations of a soil engineer and an 1 7 engineering geologist subsequent to the completion of a comprehensive ' soil and geologic investigation of the site. Permanent reproducible copies of the "Approved as Built" grading plans on standard size sheet , shall be furnished to the Building Department. B. Prior to issuance of building permits, a specific soils and foundation , study will be prepared. C. All buildings will conform to the Uniform Building Code (UBC) and city seismic design standards. ' Mitigation Measures ' Landform, geology and soil impacts have been -mitigated through measures in- , corporated into the project or they will be mitigated through compliance with the existing City policies and requirements listed above. No further mitigation measures are proposed. ' B. HYDROLOGY ' A complete discussion of hydrology issues is contained in the GPA 81-2 EIR. ' The following provides a summary of the EIR analysis. Existing Conditions ' Surface runoff within the Block 400 area flows into the existing storm ' drain system which outlets to Newport Harbor. Local groundwater tables beneath Newport Center are exposed to very little ' rainwater percolation due to large areas of paved surfacing. , Existing urban uses contribute to the pollutants (oil , gas., fertilizers, , pesticides, etc.) found in stormwater discharges from the study area. Impacts No significant impact on existing drainage patterns and flow/volumes within , the area is anticipated. 8 ' 1 ' Short-term construction-related sediment increases and long-term urban pollutant discharges will incrementally increase pollutant loads to the existing storm drain system. ' Existing City Policies and Requirements D. An erosion, siltation, and dust control plan shall be prepared by the ' applicant and approved by the Building Department. ' E. The vaccumn sweeping of parking areas and access roads at regular intervals shall be accomplished, to reduce the amount of litter and ' dirt available for suspension in runoff, in a manner approved by the Planning Department. tMitigation Measures ' Hydrology impacts have been mitigated through measures incorporated into the project or through compliance with existing City policies and requirements ' listed above. No further mitigation measures are proposed. ' C. BIOLOGICAL RESOURCES ' The Block 400 study area is presently developed and a discussion of biolo- gical resources is not applicable. ' D. CULTURAL/SCIENTIFIC RESOURCES Existing Conditions t Due to the existing developed nature of the study area, archaeological and paleontological investigations were not conducted. Any resources which may have occurred within the study area have likely been destroyed by previous ' grading and construction. ' Impacts ' No adverse impacts are anticipated. 9 Mitigation Measures ' No mitigation measures are proposed. E. LAND USE AND LAND USE REGULATION Existing Conditions Land Use t Block 400 contains professional medical office and related service commer- cial uses. As shown in Exhibit 10, four buildings are currently situated ' in the block. Table I presents a statistical analysis of the existing buildings within Block 400. Table 1 'BLOCK 400.

A detailed discussion of the proposed development's relationship to other elements of the General Plan is contained in Section 3.5 of the EIR for GPA 81-2. Zoning Code: Except for the corners of the block which are zoned for open space, Block 400 is zoned "C-O-H", limited commercial-multiple residential combining district which allows multiple residential dwellings, hotels, motels, professional office and retail sales. The combining district H designation establishes parking standards. The Zoning Code designates the minimum building site area, lot dimensions, yards/setbacks and maximum floor area for this commercial district. Impacts Land Use ' Development of the proposed seven-story 80,000 square foot office building will increase the land use intensity of the Block 400 study area. The ` impacts associated with this intensification are discussed throughout the EIR for GPA 81-2 as well as this Initial Study. ' Land Use Regulation General Plan - Land Use Element: The proposed project is consistent with the existing General Plan land use designation for Block 400. The project's relationship to other elements of the General Plan are dis- cussed in detail within the EIR for GPA 81-2. Zoning Codes: As part of GPA 81-2, the City Council adopted the Planning Commission's five recommendations relative to• Block 400. •One of the recom- ' 11 mendations was that Block 400 be rezoned to the P-C - Planned Community District. Under this zoning designation, development within Block 400 would be limited to: "Those land uses permitted by the City's General Plan at or below a density or intensity prescribed by the General Plan" (Section 20.51.025(a) of the Planning and Zoning Code of the City of Newport Beach). Pursuant to this recommendation, the project applicant is requesting a zone change from the site's existing, C-0-H designati'on to P-C. As the proposed .project is consistent with the land use and density prescribed by the General Plan, so would it also be consistent with the uses allowed under the P-C zoning designation. As part of rezoning Block 400 to a P.C. District, a 'Planned Community Development Plan has been prepared for the subject area. The development plan establishes development standards for the site and divided Block 400 into two subareas. Area 1 includes the three existing medical office buildings, the proposed medical office building, and the parking area for the four medical office buildings. Area 2 includes the Great Western Savings building and related parking ' area (see Exhibit 3). Under the provisions of the proposed Development Plan, Area 2 would maintain the existing C-04 zoning, development standards and new P.C. development standards would apply to Area 1. Table 2 provides a comparison of the development standards for C-04 zoning and the standards proposed in the Planned Community Development Plan for Area 1 of Block 400.

I , 1J F. DEMOGRAPHICS Existing Conditions The Block 400-Newport Center study area has a mix of professional office and commercial uses. Based on City of Newport Beach Planning Department employment rates, a total of 1,157 persons work in Block 400.1 Table 3 provides an estimate of land uses and employment rates used to derive the existing employment statistic. Impacts , Implementation of the proposed development will result in increased employ- ment opportunities in the B1'ock 400-Newport Center study area. As shown in Table 3, approximately 256 additional employees will be generated by the medical office use proposed for the study area. Employment created, by the proposed medical office will add to the demand for housing within h the city and surrounding areas. _ Table 3 EMPLOYEES WITHOUT/WITH PROPOSED DEVELOPMENT BLOCK 400-NEWPORT CENTER Amount of Area (sq.ft.)

The impact was considered to be acceptable when balanced against the benefit of the project, as noted in the statement of Facts and Findings and accompanying statement of Overriding Conside- rations. 1 G., TRANSPORTATION/CIRCULATION The following discussion is based upon; 1) the transportation/circulation analysis contained in the EIR for GPA 81-2, and 2) a traffic' study pre- pared for the project by Basmaciyan-Darnell , Inc. (BDI) in August 1983. The traffic study prepared by BDI is intended to supplement the information in the EIR 'and was also used in meeting the requirements of the Traffic Phasing Ordinance (TPO) of the City of Newport Beach. A more detailed description of the TPO requirements is provided later in the discussion. The complete traffic report is included as Appendix A. Existing Conditions Air Transportation John Wayne Orange County Airport is the principal general aviation facility in Orange County. Privately owned aircraft account for approxiately 90 percent of the flight activity. In 1979, the airport accommodated approxi- mately one-half (2.6 million passengers) of the commercial air passenger demand generated in the county.1 The remaining air passenger demand is accommodated at the Los Angeles International , Ontario International or Long Beach Airports. •� The airport is currently faced with several problems including vehicle traffic congestion on arterials providing access to the airport and an acute shortage of parking. Safely is also a concern due to the high volume of air traffic. The airport presently exceeds state noise standards. 1 City of Newport Beach, Certified EIR, General Plan 'Amendment 80-3, January 16, 1981. 15 The study area currently contains 73,600 square feet of professional office space and 280,000 square feet of medical office space. At this level of development, about three air passengers per day are generated (based on a rate of 0.28 air passengers per 100 employees and an estimate of 1,183 em- ployees).1 It is estimated that approximately one-half of these passengers utilize the John-Wayne - Orange County Airport. .I Vehicular Transportation/Circulation The local circulation system serving the Block 400 study area includes Avo- cado Avenue, Coast Highway, Jamboree Road, MacArthur Boulevard, Newport Center Drive,, Santa Cruz Drive, Santa Rosa Drive, San Joaquin Hills Road, San Miguel Drive and San Nicolas Drive. Exhibit 11 illustrates the 1982 average daily traffic volumes on major thoroughfares within the City. At a rate of 13 trip ends per 1,000 square feet of professional office and a rate of 40 trips per 1,000 square feet of medical office, the existing land uses withn the study area generate approximately 129157 vehicle trips per day.2 Parking A parking study for the project was completed by Basmaciyan-Darnell , Inc. in October 1983 (a copy of the study is, included in Appendix A). The study included a series of onsite parking surveys to determine ,the parking char- acteristics of the Block 400 area. Based upon the results of the surveys, it was determined that approximately 835 parking spaces are needed for the existing 271,945 gross square feet of medical office buildings within ' Block 400. This amount of parking equates to approximately 3.07 parking spaces per 1,000 gross square feet of building area. It was also, deter- mined that compact cars constitute from 33 to 52 percent of the parked cars . within Block 400, depending on the time of day and day of survey. rl 1 City of 'Newport Beach, op. cit. , January 16, 1981. 2 Trip factor for professional office taken from GPA 81-2 EIR. 16 IIII.

OF NEWPORT BEACH 1982 Average Daily Traffic BLOCK 400 _ MEDICAL OFFICE • • CITY OF NEWPORT BEACH EXHIBIT 11 Impacts Air Transportation The addition of 80,000 square feet of medical office space would generate �- 0.7 additional air passengers per day (based on a rate of 0.28 air passengers per day per 100 employees). Approximately one-half of these passengers are expected to utilize the John Wayne-Orange County Airport. Vehicular Transportation/Circulation Traffic Generation Based upon a rate of 40 daily vehicle trips per 1,000 square feet of medi- cal office, the proposed 80,000 square-foot development will generate 3,200 vehicle trips per day. Table 4 summarizes the traffic generation charac- teristics projected for the proposed development. The trip generation rates used in this analysis are based on traffic counts and field surveys ' conducted for the existing buidlings in Block 400. It is important to note that the peak hour generation rates for medical office buildings are typically lower than other commercial uses. The majority of traffic from patients utilizing medical offices occurs evenly throughout the day.

Exhibit 12 shows the project directional distribution and assignment of project traffic. Based upon this distribu- tion pattern, the resulting project-related 2 1/2 hour afternoon peak period and afternoon peak hour traffic volumes were estimated, and are pre- sented in Exhibits 13 and 14, respectively. ' Critical Intersection Analysis As noted earlier, the TPO requirements for the proposed project has been met.1 The following provides .a summarization of the analysis used for the TPO requirements. The City of Newport Beach Traffic Phasing Ordinance (TPO) requires that 'a Critical Intersection Analysis be conducted for any office, industrial or commercial development of 10,000 square feet or more. The analysis in- cludes: 1) identifying the critical intersections to be examined; 2) eval- uating project-related impacts on the 2-1/2 hour afternoon peak period traffic volumes for critical intersections; and 3) preparing Intersection Capacity Utilization (ICU) calculations for those critical intersections which exceed the TPO 1% standards. It is anticipated that the proposed development will initially be occupied in 1985 with full occupancy by 1986. The City Traffic Engi neer identified 32 critical intersections that could be affected by the project at full occupancy. Table 5 provides a list of the critical intersections and Exhibit 15 illustrates the location of each intersection. Each critical intersection was evaluated, by BDI to determine the need for an ICU analysis. For each intersections where, on any approach leg, pro- ject traffic is estimated to be greater than 1% of the projected peak 2-1/2 1 The TPO for the proposed project was approved by the Planning Commission on September 8, 1983. if ` � � � � � � � � � i � is � � � >� » r• � Newport v ON souleYer 6% a Irvin* Avenue % 10% ut 2% 6% i 2% • Dover Drive 16% a c i Eaerb4j o • ' 10% —10% • O a Jamboree 3% to 10 10% 7% aftpoad a O �•�Crut 4 ,•o44V 7% 6% • � •oN •a�n � o - •c �• Newport r° y e% 2% • o u� r�GeP score n 10% n to �`; ; o, x 10% o • iR o OJEC 20% o a y Avooetl '>':.:.{•N.,-`•.�� n SITE ; 12% ° 00 n e 10% 67% 20% M•oArthur oobeorort 10% Bou•va 21 ' 20% LEGEND • 26% 6% 20 PERCENTAGE OF PROJECT- 2% Drive o 2% M•r Beo b!uu Drlr!t t0 et • RELATED TRAFFIC s • Avenuer • 1% 15% 6% SOURCE: B.D.I.'

The results of the 1% analysis identified 14 of the 32 critical intersections as needing an ICU analysis. These 14 intersections are indicated on Table 5. The worksheets used in the 1% analysis are included in Appendix A. Table 6 summarizes the results of the ICU analysis conducted for the 14 subject intersections. The scenarios presented in Table 6 include existing conditions, projected conditions for 1986 with approved developments and regional traffic growth, and projected conditions with project traffic ' added. As shown, all but two of the fourteen critical intersections evalu- ated have an acceptable (by City standards) ICU rating of less than 0.9000. By 1986, two of the fourteen critical intersections will have ICU's greater than 0.9000 with traffic from regional growth and approved developments. The addition of project-related traffic of these same two intersections adds incremental traffic impact to these projected levels. These intersec- tions are Jamboree Road at Bristol Street North, and Jamboree Road at Coast Highway. The following provides a brief description of the ICU character- istics of these two intersections. ' Jamboree Road at Bristol Street North. As indicated in Table 6, the inter- section is projected to have an ICU value of 0.9078 in 1986 without the project, and an ICU value of 0.9107 with the project. Completion of the extension of the Corona del Mar Freeway is anticipated by 1986. This free- way project will modify the intersection so that the current left turn to I reach the freeway would be a right turn to an on-ramp, and northbound through traffic would not- be stopped. Assuming that 15 percent of the ' northbound left turn will remain as trips with local destinations, the ICU value would be reduced to 0.6647. Jamboree Road at Coast Highway. This intersection is projected to have an ICU value of 0.9162 without the project and an ICU of 0.9241 with the project in 1986. This ICU would be reduced if the westbound right turn lane on Coast Highway were to be converted to an optional through and ■ right turn lane. The resulting ICU with such an improvement would be 0.8562 in 1986, including traffic to/from committed projects and the pro- posed medical office expansion. 1C Table 5 LIST OF CRITICAL INTERSECTIONS- Project-Related' Traffic Exceeds 1% of 2-1/2 Hr.

Parking The proposed addition of 80,000 square feet to the project site would increase the total building area to 351,945 square feet (271,945 + 80,000) and a total of 1,080 parking spaces (351,945 x 3.07/1,000) would be needed. Included in the parking proposal is a two-story parking structure which will provide additional parking spaces. The total number of parking spaces provided in the Block 400 study area upon completion of the project would be 1,247 which provides a ratio of 3.54 parking spaces per 1,000 square feet (gross) of total building area. This number of parking spaces is approximately 18 percent greater than the amount of parking recommended by the project traffic consultant, thus providing more than ample parking for the Block 400 study area. , Existing City Policies and Requirements F. The project shall be required to contribute a sum equal to their fair share of future circulaton system improvements as shown on the City's Master Plan of streets and Highways. Mitigation Measures 1. The ,requirements of the approved Traffic Study shall be made, and the westbound right-turn lane at the intersection of Coast Highway/'Jamboree Road should be converted to an optional right-turn and through traffic lane. This would necessitate the construction of an additional west- bound lane exiting from the intersection. Such a modification will result in less congestion at the intersection and will improve the 1986 ICU rating to an acceptable level of 0.8562. , H. ACOUSTIC ENVIRONMENT The following analysis is based primarily upon the comprehensive noise measurement survey and computer modeling noise study which was conducted for GPA 81-2 and is discussed in the GPA EIR. 22 0 Existing Conditions The Block 400 study area is not subject to exterior noise levels over 65 CNEL; however the site is subject to noise levels of 50 to 60 CNEL gener- ated by military helicopters operating out of MCAS(H)-Tustin. Impacts The project site and surrounding vicinity will be subject to short-term acoustic impacts during project grading and building construction activi- ties. Each discrete construction phase will have its own mix of equipment and consequently its own noise characteristics. Noise from earthmoving equipment may range from 73 to 96 dBA at 50 feet. Typical operating cycles may involve one to two minutes of full power operation followed by ' three to four minutes at lower power. Table 7 delineates additional construction equipment noise ranges by category. Noise and vibration from ' construction activities could affect the use of sensitive medical moni- toring equipment and other medical activities within Block 400. Long-term acoustic impacts from the proposed development are those associ- ated with project-generated traffic. Implementation of the proposed development will not create a significant increase in long-term noise levels onsite and the use will not be subject to exterior noise levels in excess of 65 CNEL. However, the distribution of project-generated traffic onto the local circulation system will result in an incremental increase 1 in noise levels adjacent to the affected roadways. Table 8 depicts the increase in the existing noise levels due to traffic from the project. ' The effect of this roadway noise increase is more notable for noise-sensi- tive land uses adjacent to affected roadways. Of particular concern in regards to noise sensitive uses adjacent to roadways affected by project traffic is the Irvine Terrace residential community. This community is located south of and adjacent to Pacific Coast Highway between Jamboree Road and Newport Center Drive. Future noise levels within Irvine Terrace are projected to exceed City criteria regardless of whether or not the proposed development is implemented. 23 I� TABLE 7 CONSTRUCTION EQUIPMENT NOISE RANGES , NOISE LEVEL(dBA) AT 50 FT 60 70 60 90 100 110 COMPACTORS 01OLLERS) H m FRONT LOADERS BACKHOES 0, TRACTORS H SCRAPERS, GRADERS PAVERS H ' TRUCKS CONCRETE MIXERS m CONCRETE PUMPS H CRANES (MOVABLE) I-- CRANES (DERRICK) H PUMPS 4 GENERATORS W F COMPRESSORS , k PNEUMATIC WRENCHES f� JACK HAMMERS AND ROCK DRILLS t0u PLE DRIVERS (PEAKS) VIBRATOR O SAWS NOTE:BASED ON LIMITED AVAILABLE DATA SAMPLES. ,. � 1I SOURCE: EPA, 1971:*NOISE FROM CONSTRUCTION EQUIPMENT AND OPERATIONS, BUILDING EQUIPMENT, AND HOME APPLIANCES-. NTD3000.1 24 r Project-generated traffic utilizing Pacific Coast Highway will cause an incremental increase in noise levels affecting this residential area. Generally, a 2 to 3 dBA increase in noise levels is necessary to be considered significant. "Noise wall funds" have been and will continue to be established by the City to initiate mitigation of traffic noise for the older residential areas of the community. Applicants for committed and proposed projects are required to contribute to a fund if it is determined that their projects are incrementally increasing the traffic volumes and noise adjacent to these sensitive residential areas.

Noise wall funds have been established for Jamboree• Road, West Newport , and Irvine Terrace. The project shall be required to contribute a sum equal to their fair share for each fund. Mitigation Measures 2. Only quieted or "hushed" models of construction equipment suitable for work in hospital zones shall be used. 3. Pavement breaking and hauling shall be conducted only on weekends to ' avoid disturbance of existing nearby medical offices. 4. Noise generating activities and equipment shall be located as far as practicable from the existing office buildings to effectuate noise reduction achieved by distance. Affected activities include, but are not limited to, trucking, concrete delivery and pumping, welding, power generation, and compressed air supplies. 5. All tenants of the medical office buildings within Block 400 shall receive a schedule of construction activities prior to initial ground- breaking, and shall be notified of any major change(s) to the set schedule. I. AIR RESOURCES Existing Conditions The study area is located within the South Coast Air Basin (SCAB). The air quality of the basin is determined by the primary pollutant emissions added N in the air mass. daily, and b the secondary pollutants already present Y Y Primary pollutants are emitted directly from a source and include carbon monoxide (CO), nitric oxide and nitrogen dioxide (NO and NO2), sulfur dioxide (SO2), particulates and various hydrocarbons (HC). Secondary pol- lutants are created with the passage of time, in the air mass, and include ozone (03), photochemical aerosols and peroxyacetylnitrate (PAN). 26 ' Air quality conditions at the site is a function of the primary pollutants emitted locally, the existing regional ambient air quality, and the meteor- ological and topographical factors which influence the intrusion of pollu- tants into the area from sources outside the immediate vicinity. Climatel The study area has a Mediterranean-type climate (warm summers and mild. win- ters). The climatological monitoring station nearest the site is the Newport Beach Harbor station. Available 1982 data indicates that the annual precipitation was 11.11 inches. Most rainfall occurs between November and April when the permanent high pressure system in the eastern Pacific weakens. Temperatures recorded during 1982 range from a high of 880 F to a low of 370 F, with an annual average temperature of approximately 60.60 F. ' Generally, winds with 5- to 10-mile-per-hour speeds flow offshore during ' the nighttime hours and are replaced by onshore breezes of the same magni- tude by 10 a.m. Summer months usually include a northwesterly and south- easterly flow pattern superimposed upon the daily sea breeze. Air Quality Ambient Air Quality ' Ambient air quality data is usually described in terms of compliance with state and federal standards, which have been adopted to protect public health with some margin of safety. In addition to ambient standards, Cali- fornia has adopted episode criteria for oxidant, carbon monoxide, sulfur dioxide and particulate matter. Episode criteria levels represent short- term exposures at which public health is actually threatened. In Orange County, air quality data is collected primarily by the South Coast Air Quality Management District (SCAQMD). The closest operating monitoring station is located in Costa Mesa and provides air quality data 1 National Oceanic and Atmosphere Administration, Climatological data Annual Summary, V. 86, n. 13, 1982. 27 which can be considered to be indicative of the conditions in the general vicinity of the project site. Available air quality data from the Costa Mesa station during 1982 is summarized below. Oxidants represent the major air quality problem within the South Coast Air Basin. Ozone levels monitored at the Costa Mesa station exceeded State standards on 25 days during 1982. State standards for carbon monoxide were exceeded on 5 days. Nitrogen dioxide and sulfur dioxide levels ' remained well below state standards during 1982. Particulate concentra- tions are not monitored at the Costa Mesa station. , Existing Emissions The Block 400 study area is currently developed with general office and medical office uses. Pollutant emissions from existing land uses include emissions from stationary and mobile sources. Stationary source considera- tions include onsite emissions from space and water heating devices and offsite emissions at the power plant associated with the generation of electricity. Mobile source considerations include emissions from traffic generated by existing uses. Table 9 presents the amount of stationary and mobile source emissions generated from existing land uses on the project site. , Table 9 EXISTING STATIONARY AND MOBILE SOURCE EMISSIONSI Stationary Mobile Total from Primary Source Emissions Source Emissions Both Sources Pollutant (Tons/Day) (Tons/Day) (Tons/Day) CO '0.00349 2.22401 2.22750 HC 0.00306 0.21195 0.21501 NOx 0.03899 0.37166 0.41065 sox 0.04391 0.04179 0.08570 , Particulates 0.00673 0.05075 0.05748 1 Source: City of Newport Beach, GPA 81-2 EIR, April 1982. 2£ 1 1 Impacts Climate Development of the project may influence the micrometeorological conditions in and around the Block 400 study area. Construction of the proposed 7-story, 80,000 square foot office building may affect the direction and velocity of winds local to the project site. Also, areas immediately adja- cent to the proposed office building may experience a change in surface/air ' temperatures due to shading and reflection from the proposed structure. The extent of micrometeorological impacts is not anticipated to be signifi- cant. Air Quality Implementation. of the proposed development will result in short-term con- struction-related air quality impacts as well as long-term impacts associ- ated'with usage of the proposed structures. Short-Term Impacts ' Preparation of the site for development will produce two types of air con- taminants on a short-term basis: exhaust emissions from construction equipment and fugitive dust generated as a result of grading. These emir- ' sions produced during grading and construction activities, although of short-term duration, could be troublesome to workers and adjacent proper- ties. Each of these is discussed in greater detail below. ' Construction-Related Exhaust Emissions: Development of the project may involve heavy trucks, earthmoving equipment, air compressors, generators, and other equipment which utilize internal combustion engines. Exhaust emissions from such equipment can be anticipated to be comparable to other development projects and will not have a significant effect on state and federal air quality standards. Fugitive Dust Emissions: Construction activities are a source of fugitive ' dust emissions that may have a substantial temporary impact on local air ' 29 quality. Grading and building construction are the development activities ' with typically the highest dust emission potential , but, due to the minimal amount of grading necessary for the proposed development, project dust emissions are anticipated to be insignificant. Long-Term Impacts Long-term air quality impacts are those associated with permanent usage of the facilities proposed for Block 400. Air pollutants generated by the proposed development can be projected as the sum of both stationary and ' mobile source emissions. Table 10 ,provides a "summary of the Block 400 emissions projected for 1995. For comparison purposes, the summary ' includes future emissions with and without the proposed devel'opment.l Table 10 1995 STATIONARY AND MOBILE SOURCE EMISSIONS - WITHOUT/WITH PROJECT2 ' Stationary Mobile Total from Both , Source Emissions Source Emissions Sources Without/ Primary Without/With Project Without/With Project With Project Pollutant (Tons/Day) (Tons/Day) (Tons/Day) ' CO .0035/:0042 .7941/1.0050 .7076/1.0092 HC .0031/.0031 .0866/0.1096 .0897/0.1133 NOx .0390/.0467 .2090/0.2645 .2480/0.3121 Sox .0439/.0538 .0418/0.0529 .0857/0.1067 Particulates .0067/.0082 .0508/0.0642 .0575/0.0724 ' Mitigation Measures ' Due to the absence of significant air quality impacts, no mitigation , measures are proposed. _ 1 Emissions for existing land uses in Table 8 differ from those found in Table 7 due to lower mobile source emission rates anticipated for 1995.

ENERGY CONSUMPTION Existing Conditions Based on an electricity consumption rate of 34.2 kwh per year for each square foot of office, existing offices in Block 400 consume approximately 12 million kwh of electricity per year.1 Based on a natural gas usage rate ' of 42 cubic feet per year for each square foot of office space, offices in Block 400 use approximately 6.5 million cubic feet of natural gas per ' year.2,3 ' Impacts ' Development of the proposed project will result in increased energy consumption during site development and after occupancy. Based upon the aforementioned electricity consumption rate of 34.2 kwh per year for each ' square foot of office, the proposed 80,000 square-foot office will consume approximately 2.74 million kwh annually. The proposed medical building will not utilize natural gas. ' Mitigation Measures The following conservation measures are recommended to reduce the energy ' requirements of the proposed development. ' Building Envelope 6. Energy-efficient tinted glass is proposed for the exterior of the of- fice building. ' 7. Interior walls between conditioned and unconditioned spaces within the proposed building shall be adequately insulated to prevent undesired heat transfer. 1 Electricity consumption rate from South Coast Air Quality Management District, op. cit., October 1980, Table X, p. 57. 2 Only the 80,000 square foot medical building and the 73,600 square foot general office building utilize natural gas (Frank• C. Rhodes, Jr., Newport Center Medical Buildings, March 11, 1982) 3 Natural gas usage rate from South Coast Air Quality Management Dis- trict, op. cit., October 1980, Table XI, p. 58. J± 1 &. Air infiltration, via doors and windows in exterior walls and adjacent to unconditioned spaces, shall be minimized through proper design and use of weatherstripping. ' Heating Ventilation and Air Conditioning (HVAC) 1 9. Determination of design loads for heating and cooling requirements shall be in accordance with procedures described in the latest ASHRAE Handbook of Fundamentals. 10. HVAC equipment for the proposed office shall meet or exceed the oper- ating efficiency standards specified in the State Appliance Efficiency , Regulations. 11. HVAC equipment should be designed with an economizer cycle to maximize r the efficient use of outside air in meeting interior heating/cooling requirements: 12. Necessary maintenance information shall be supplied by the manufacturer ' for HVAC equipment requiring periodic maintenance for efficient opera- tion. Service of HVAC equipment should be maintained on a regular basis as a part of a building maintenance program. Service Water Heating, ' 13. All water heating devices within the proposed office shall meet or ex- ceed the operating efficiency standards specified in the State Appli- ance Efficiency Regulations. , 14. Health codes only require tepid water for hand washing and a range of 1050 F to 1200 F water temperatures for health care facilities. Small ' end-use water heaters can be used to boost water temperatures for spe- cial high-temperature medical uses. The use of a low-temperature pri- mary hot water system, backed by end-use water heaters, where needed, should be considered in the design of the proposed building. 1 32 r 15. All hot water lines shall be insulated to provide hot water faster with less waste (in the case of non-circulating hot water systems) and pre- vent heat undesired heat transfer. Lighting 16. The design of the interior lighting system shall incorporate the following practices: ' - Use of natural daylight designed for general lighting or specific task applications; - Use of the most energy efficient light source available suitable for the given application; Use of the most effective type of light and lighting source for ' the given application; - Attention to system maintenance in both design and operation, so that planning for system deterioration does not require excessive ' initial wattage; and Design of the system to allow for flexible control.. ' 17. Exterior lighting design should maximize the use of energy efficient High Intensity Discharge lighting sources. Such sources include, in ascending order of efficiency, mercury lamps, metal halide lamps and high pressure sodium lamps. ' System Controls 18. The operation of mechanical and electrical equipment associated with ' the proposed development should be systematically controlled to maxi- mize efficiency and reduce energy consumption. Given the size of the ' proposed building, consideration should be given to the utilization of a computerized Energy Management System to regulate, coordinate, and integrate the operation of individual systems (i .e., HVAC equipment, 00 JJ lighting, compressors, elevators, etc.) within the development. At a ' minimum, time clocks should be utilized to limit the unnecessary use of energy during non-business hours, and to reduce electrical loads ' during peak-demand periods. K. AESTHETICS ' Existing Conditions ' Newport Center is a distinct and highly visible regional landmark. The , complex is comprised of a variety of low and high-rise structures exhi- biting a wide range of shapes and surface textures. The northeastern ' quadrant, within which Block 400 is situated, is dominated by an urbanscape of high-rise buildings. Block 400 is presently developed with four high- rise buildings along the east and west sides of an internal parking area ' (see Exhibits 16 and 17).. Views from surrounding areas on the south and southwest look through Block 400 to similar high-rise developments on the ' north. Westerly and southerly views look through to the Pacific Ocean, Newport Harbor and Balboa Peninsula areas in the distance. Views looking ' !I east and southeast through Block 400 primarily encompass the surrounding hillside residential areas. Impacts i The .proposed office building and related parking facility will intensify the urban appearance of Block 400 and add another structural element to the ' Newport Center skyline. The proposed seven-story building will partially obscure existing views ' through the study area. Those areas which will experience view impacts from the project include the five-story Cal-American commercial building , located directly north of and' adjacent to Block 400 and nearby residential areas located to the east. Views from the Big Canyon residential area , will not be significantly affected due to the elevation difference, and existing buildings and dense vegetation situated between the project site ' and Big Canyon homes. 34 I ' 0{Ii` �j M1ifa. � �`�C`,^�- \ \+ cNIaS L`,.v` •'cY/F� 1 a .� -- _ iv'e 1 1$i Cr-"..c .V / SS 93 �` _i � ivi Np y �•!• ` /g _� _ -:_ -__^,y.:� r,$ram. +� �'(f1 ' ��� •-= -.-/'��G , .`:{ v1 ;'�v Qri; � � �'l..c .• � BM` ''�-:-'-,l , !t r � U•7 „men 3 \ { I .�i =�•.. .zzs'!..�, !! -:� ��_ ` \, LEY S], I \\` , ' j �tide`fi✓ � � �{256?�'. 1 .`�tt i` t�.�^�ti> _ 'F� �: `'�(•��`^'l`eR�\ r! -Eio r{,�n j it ,�,� ; ,r.

Currently, Harbor Point has been developed with infrastructure improvements and lot grading only. No dwelling units have been constructed on the site. Development of the proposed seven-story medical office building will reduce ' the potential ocean views available to future residential units within Harbor Point. Exhibit 18 presents the expected westerly views from Harbor Point and the southerly view from the Cal-American building. ' Views from more distant residential areas will not be substantially ' affected by the proposed building. Exhibit 19 presents the expected views from other residential areas within the project vicinity. Potential view impacts resulting from the construction of a seven-story, ' 80,000-square foot office building have been reduced considerably by orienting the 186' length of the building on a north-south axis. Desirable southerly views towards the ocean would have been substantially obscured ' had the length of the proposed building been oriented on an east-west axis. As proposed, only the 67' width of the building will block views directly ' to the south. Potential impacts to westerly views have been reduced by aligning the proposed building with the two existing multi-story office ' buildings located in the southern portion of Block 400, thus helping to maintain the existing westerly view corridors. tMitigation Measures ' Due to the absence of significant aesthetic impacts, no mitigation measures are proposed. 1 1 '5 J - 1 1 � 1 IV.

This report has been prepared in accordance with the requirements of the Traffic Phasing Ordinance (TPO) of the City of Newport Beach. The infor- mation presented is a supplement to the traffic study contained in the EIR for General Plan Amendment (GPA) 81-2. Project Description The proposed 80,000 square foot medical office building is to be located in Block 400 of Newport Center. Block 400 is bounded by San Miguel Drive and San Nicholas Drive, and by Newport Center Drive East and Avocado Avenue. Figure 1 is a vicinity map depicting the location of the Block 400 project. Vehicular access to the site would be from San Miguel Drive and from San Nicolas Drive. The location of the project and the adjacent development within Block 400 are illustrated in Figure 2. EXISTING CONDITIONS In Block 400, the site proposed for development, there are now li three buildings with a total of 271 ,945 gross square feet of medical office. Approximately 1200 parking spaces for the three buildings are provided. The gross square footage for the three buildings is as follows: Building I - 80,000 s Building II - 100,497 Building III - 91 ,448 Total 271 ,945 gross square feet The location of each building and the proposed project is depicted in Figure 2. Existing Traffic Volumes The existing (1982) average daily traffic- (ADT) volumes for the , streets in the vicinity of the project are presented in Figure 3. The source of these traffic volumes is the City of Newport Beach Traffic Engineering Department.

Daily machine counts at each of the access drives were made as well as manual turning movement counts duringthe afternoon peak period between 3:00 and P 6:00 PM. The data collection was performed on June 28, 29 and i 30, 1983 (Tuesdaythru Thursday) . During these times the complex )Y g P was approximately 45% leased and occupied. Based on the traffic counts and the size of the existing buildings, daily and peak hourly trip generation rates were computed. These were then utilized for analyzing the traffic impacts of the proposed project. The trip generation rates are presented in the following section of this report. .PROJECT-RELATED TRAFFIC To estimate what effect the traffic volumes generated by the Block 400 project would .have on the surrounding circulation > system, a three-step process was used. First, the traffic that will be generated by the project was determined. The generated trips were then geographically distributed to major trip attractors in the area surrounding the project. (The trip attractors include employment centers, commercial centers, resi- dential areas. ) Finally, the project-related traffic was assigned to specific roadways. Trip-Generation The trip generation rates used in this analysis are based on the counts and field surveys conducted for the existing buildings in Block 460. The resulting generation rates were discussed with the City Traffic Engineer and represent the existing and projected tripmaking characteristics of the project. Table 1, presents results of the trip generation studies for the project site. TABLE 1 TRIP GENERATION SUMMARY FOR BLOCK 400 AND RECOMMENDED TRIP GENERATION CHARACTERISTICS Daily : 40 Trip Ends/1 ,000 sq. ft. of gross building area. Afternoon Peak Hour (4:30-5:30 PM) Inbound . 40 trip ends/1 , 000 sq. ft. of gross building area. Outbound 1 .90 trip ends/1 ,000 sq. ft. of gross building area. 2-1 /2 Hr.

Outbound 4.00 trip ends/1 ,000 sq. ft. of gross building area. 5 ,� I � Based on the trip generation rates in Table 1 , the proposed development of 80,000 square feet of gross medical office space would generate 3,200 daily vehicle trip ends. During the after- noon peak hour, 184 trip ends would be generated; during the afternoon 2-1 /2 hour peak period 448 vehicle trip ends would be generated. Table 2 is a summary of the estimated tripmaking to/from the proposed project.

The resulting trip distribution pattern is depicted in Figure 4. The traffic that would be generated by the proposed medical office development was then assigned to the surrounding street system in accordance with the distribution pattern shown on Figure 4. The resulting project-related 2-1 /2 hour afternoon peak period and afternoon peak hour traffic volumes are presented in Figures 5 and 6, respectively. TRAFFIC PHASING ORDINANCE (TPO) The City of Newport Beach Traffic Phasing Ordinance (TPO) requires the review of potential external traffic impacts on critical intersections for any office, industrial or commercial development of 10, 000 square feet or more and any residential development of 10 dwelling units or more. The process requires the identification of critical intersections to be examined, analysis of the impacts of the project on the 2-1 /2 hour after- noon peak period traffic volumes for critical intersections and, finally the preparation of Intersection Capacity Utilization Newport 8% gouN•vard ex kvloe Averwe -In % 2% 8% 1bx : mxM 2% ..

Should the ICU value yield an unsatis- factory Level of Service (LOS "E" or ICU greater than 0.9000) then additional analysis and identification of specific mitiga- tion measures are required. The proposed Block 400 Medical Office project will initially be occupied in 1985 with full occupancy by 1986. The City Traffic Engineer has identified 32 critical intersections that could be. affected by the proposed project at full occupancy. Table 3 is a list of the 32 intersections. Figure 7 is an illustration of the location of the 32 intersections. The first step in evaluating the intersections is to conduct the M 1 % Traffic Volume Analysis. 'The 1 % Traffic Volume Analysis takes into consideration existing traffic, regional growth and approved projects traffic. For those intersections where, on any approach leg, project traffic is estimated to be greater than 1 % of the projected peak 2-1 /2 hour traffic volume, Intersection Capacity Utilization Analysis (ICU) is required. The results of the 1 % analysis identified 14 of the 32 critical intersections where ICU analyses would be required. No ICU analysis would be required at the remaining 18 intersections. Table 3 is a summary of the results of the 1 % traffic volume analyses. Appendix A contains the worksheets for these analyses. ICUs were calculated for the fourteen (14) critical intersec- tions listed in Table 3 followed, by a "yes" The results of the ICU analyses are summarized in Table 4 and copies of the ICU worksheets are contained in Appendix B. A summary of the ICU' s for the 14 critical intersections are presented in Table 4. ICU' s are presented for existing condi- tions, expected conditions in 1986 with approved developments and regional growth traffic, and finally the resulting ICU' s in 1986 with project- related traffic added. In 1986 two of the fourteen critical intersections will have ICU' s greater than 0. 9000 with the regional growth and approved developments traffic. The addition of project-related traffic results in the same two intersections further exceeding an ICU of 0. 9000. These intersections are Jamboree Road at Bristol Street North and Jamboree Road at Pacific Coast Highway. Additional analyses of these two critical intersections has been performed and is discussed in the following paragraphs. Jamboree Road at Bristol Street North As indicated in Table 4, the intersection is projected to have an ICU value of 0.9078 in 1986 without the project and an ICU value of 0.9107 with the project. Completion of the extension of the Corona del Mar Freeway is anticipated by 1986. This project will modify the intersection so that the current left turn to reach the freeway would be a right turn to an on-ramp, and northbound through traf- fic would not be stopped.

This analysis is also presented in Table 4; the value would be 0. 6647 with the freeway extension. tJamboree-Road-at Pacific Coast Highway. This intersection is projected to have an ICU value of 0.9162 without the project and an ICU of 0.6647 with the project in 1986. Mitigation of this project can be accomplished by the conversion of the westbound right turn lane on Pacific Coast Highway to an optional through and right turn lane. The resulting ICU with this improvement would be 0.8562 in 1986 , including traffic to/from committed projects and the proposed medical office expansion. SUMMARY OF FINDINGS AND CONCLUSIONS - The report has been prepared in accordance with the requirements of the Traffic Phasing Ordinance (TPO) of the City of Newport Beach for the construction of a fourth medical office building in Block 400 of Newport Center. The proposed building would have 80,000 square feet of gross area. The three existing buildings have a total of 271 , 945 gross sq. ft. - Trip generation rates for the existing buildings were — established on the basis of actual traffic counts at the driveways. For the proposed building, these trip generation rates are used. - Daily traffic to/from the proposed building would be 3,200 vehicles. In the afternoon peak hour there would be 152 outbound and 32 inbound vehicles. During the 2-1 /2 hour afternoon peak period, there would be 320 outbound and 128 inbound vehicles. ' - The City of Newport Beach has identified 32 intersections where the traffic impacts of the proposed building must be analyzed. At 14 of the 32 intersections traffic to/from the proposed building would exceed one percent of the traffic at the intersection at least on one approach. In accordance with the stipulations of the TPO, intersection capacity utilization (ICU) analyses would be required and were performed) at these 14 intersections. - At two of the 14 intersections the ICU would be in excess of 0. 9000 in 1986 considering existing traffic plus regional growth, plus traffic to/from committed projects. The addition of traffic to/from the proposed medical building would further i increase the ICU at these two intersections. The two inter- sections are Pacific Coast Highway at Jamboree Road and Bristol Street North at Jamboree Road. - At Pacific Coast Highway/Jamboree Road the 1986 ICU would be 0.9162 without the proposed building and 0.9241 with the proposed building. Therefore, improvements to reduce the ICU Ito a level below 0. 9000 would be required. . . ' 14 At Bristol Street North/Jamboree Road the 1986 ICU would be 0.9078 without the proposed building and 0.9107 with the proposed building. Therefore, improvements to reduce the ICU to a level below 0.9000 would be •required. Appropriate improvements at the two intersections are presented in the following section. MITIGATION MEASURES r - At the intersection of Pacific Coast Highway/Jamboree Road, ■ convert the westbound right-turn-only lane to an optional right-turn and through traffic lane. This would of course necessitate the construction of an additional westbound lane exiting from the intersection. With this improvement the 1986 ICU would be 0.8562, including traffic to/from the proposed building. - At the intersection of Bristol Street North/Jamboree Road the extension of the Corona del Mar Freeway to MacArthur Boulevard would alter traffic patterns and turning movements, since there would be an interchange of the Corona del Mar Freeway at Jamboree Road. With the Corona del Mar Freeway improvements and expected shifts in traffic movements the 1986 ICU would be 0.,6647, including traffic to/from the proposed project. . 1 r i 15 i i 1 . ! 1 1 Appendix A 2.5 Hour Peak Hour - 1% Analysis Worksheets ' 1% Traffic Volume Analysis Intersection San Joa uin Hi11s Rd.

Development within Block 400 con- sists of 271,945 square feet of gross building area within three buildings. The net leasable area is 227,316 square feet. ' The net leasable area represents 83. 6% of the gross building area. During the month of August, when the first set of parking sur- veys were conducted, 216, 499 square feet of space was leased. This represents 258,970 square feet of gross building area. Based on the peak parking demand for August 16, 1983 of 745 vehicles, the following parking demand rates are estimated. Parking Spaces/Gross Building Area = 2. 88 spaces/KSF (745 _ 258. 970) ' Parking Spaces/Gross Leasable Area = 3. 44 spaces/KSF (745 : 216. 499) The September parking counts, the second set of surveys, yielded a peak demand of 798 parked vehicles at 3 :00 PM on Tuesday Septem- ber 27, 1983. During September 217,099 of building area was ' leased. This represents 259,688 square feet of gross building area. The peak September parking demand for the project is esti- mated as follows : ' Parking Spaces/Gross Building Area (a) = 3. 07 spaces/KSF (798 - 259. 688) Parking Spaces/Gross Leasable Area (a) = 3. 67 spaces/KSF (798 . 217. 099) (a) Gross Building Area = Total building area. ' Gross Leasable Area = Total building area leased to tenants, excludes elevator shalls , corridor' s etc. Mr. Fred Talarico City of Newport Beach October 10, 1983 Page Two These peak parking demand rates represent the highest demand dur- ing the four data collection time periods.. The four survey days were Tuesday August 16, 1983, Tuesday September 20, 1983, Thursday September 22, 1983 and Tuesday September 27, 1983. The number of ' parked cars were counted every half hour between 7:30 AM and 5:30 PM. A copy of the summary sheets for each day are attached. Also attached is an exhibit showing the breakdown of each subarea of , the entire parking facility. Based on the four day parking demand data, the existing Block 400 medical offices (271,945 square feet of gross building area) would need 835 parking spaces (271.945 x 3. 07) . The proposed addition of 80,000 square feet to the site would ' increase the total building area to 351,.945 sq. ft. (271,945 + 80, 000) , and total of 1,080 parking spaces (351. 945 x 3. 07) would be required. , To be assured that sufficient parking would be available at all times it is recommended that more parking spaces be provided than the number calculated on the basis of the peak parking demand re- , corded during the four survey days. An increment of 10 to 15 per- cent may be appropriate. Using a 15 percent increment would re- sult in the need for 1242 parking spaces or a ratio 3.53 spaces , per thousand square feet of gross buildling area. During the parking surveys, parked cars were stratified by "compact" and "regular" sized. The percentage of compact cars are also pre- ' sented in the attached summary tables. Compact cars constitute from 33 to 52 percent of the parked cars depending on the time of day and day of survey. ' Please call me if you have any questions.
