Ramirez, Associate Planner (949) 644 -3230, gramirezecity .newport- beach.ca.us SUBJECT: Use Permit No. 2004 -046 and Traffic Study 2004 -006 (PA2004 -257) 20162 Birch Street APPLICANT: Rick Wood representing Birch Medical Office Center REQUEST The applicant requests approval of a use permit to allow the conversion of a portion of an existing general office building to medical office use. The existing building is approximately 32,278 square feet, of which approximately 16,257 square feet are proposed for medical office use. Approval of a traffic study pursuant to the Traffic Phasing Ordinance (TPO) is also requested. Approve Use Permit No. 2004 -046 and Traffic Study No. 2004 -002 subject to the findings and conditions of approval included within the attached draft resolution. DISCUSSION Site/Project Overview The existing building and site improvements received approval of a Use Permit from the County of Orange in 2001 for the initial construction on the approximate 1.54 acre site. At that .time it was determined that the development met all building development regulations including floor area ratio, building height, setbacks, parking and landscaping as prescribed by the Santa Ana Heights Specific Plan. The proposed conversion consists of interior tenant alterations and improvements to general medical office uses and minor modifications to the parking lot in order to achieve the required number of parking spaces. No exterior changes to the building are proposed and the project as requested remains in compliance with all applicable development regulations. Birch Medical Office Center April 21, 2005 Page 3 The property is located within the Santa Ana Heights Specific Plan (Business Park) and has a General Plan land use designation of Administrative, Professional, & Financial Commercial. Site /Project Characteristics Lot Area: 67,337 square feet FAR Permitted: 0.5 FAR Existing: 0.479 Building Square Footage: Proposed: 32,278 gross sqft. Proposed Use Square Footage: Medical Office Use: 16,257 sqft. General Office Use: 14,131 sqft. Stairs, Elevator, Mechanical: 1,890 sqft. Parking Required: 122 Existing Parking Provided: 120 spaces Proposed Parking: 122 spaces Analysis The proposed medical office use is subject to the approval of a use permit by the Planning Director as specked by the Santa Ana Heights Specific Plan, however, since the Traffic Study requires Planning Commission approval, the use permit request comes before the Commission as well. A traffic study is required pursuant to the Traffic Phasing Ordinance (TPO) when a project will generate more than 300 average daily trips (ADT). The City Traffic Engineer prepared a preliminary estimate of trips and concluded that a traffic study would be required for the proposed medical office building. A traffic study has been prepared by Austin Foust Associates, Inc. (Exhibit 2) under the supervision of the City Traffic Engineer pursuant to the TPO and its implementing guidelines. Additionally, the Traffic Engineer prepared a supplemental analysis that included a follow -up ICU analysis. These two documents will be cumulatively referred to as the "traffic study" in this report. Parking The existing development, approved by the County, provides 120 parking spaces for 29,944 square foot building (11250 gross). Staff analyzed parking based on a slightly different square foot total of 30,388 based upon the city's parking standards that use net square feet for office uses and gross square feet for medical office uses. Mechanical equipment rooms, elevator shafts and stairwells were not included in the original parking calculation based upon the County's methodology for calculating gross square footage and parking. The result is a total of 122 parking spaces required based on a 1/250 parking requirement for both types of office uses. Although the existing requirement is 1/200 for medical office uses, this project had a complete development review application on file with the City thereby allowing it to be parked at the previous 1/250 rate which is consistent with the ordinance adopted by the City Council. I Birch Medical Office Center April 21, 2005 Page 4 In addition to the two space increase, the Building Code requires a higher percentage of disabled parking spaces for medical office uses that will increase the number of disabled spaces from 5 to 10. Therefore, a portion of the parking lot will be re- striped and several of the landscape fingers may have to be slightly reduced in size to accommodate these larger spaces. The reduction in landscaping is minimal and the resulting plan revisions remain compliant with landscape standards. Use Permit The use permit request is for the conversion of general office space into medical office use as required by the Santa Ana Heights Specific Plan regulations. No inpatient uses are requested or permitted, nor will uses that render patients incapable of unassisted self preservation requested or permitted, at this time. In order for the Planning Commission to approve the requested Use Permit, the following findings must be made. That the proposed location of the use is in accord with the objectives of this code and the purposes of the district in which the site is located. The proposed medical use is located in an area designated as Business Park by the Speck Plan District No. 7 district, which is a business office designation. The existing office building was originally constructed in compliance with all applicable development regulations related to setbacks, building height, floor area and has not proven to conflict with surrounding uses or proven inconsistent with the APF zoning district. Medical office uses are consistent with this zoning designation and are allowed with a use permit. Additionally, it is not likely the medical office use within the existing building will prove incompatible with the surrounding area. 2. That the proposed location of the use permit and the proposed conditions under which it would be operated or maintained will be consistent with the General Plan and the purpose of the district in which the site is located; will not be detrimental to the public health, safety, peace, morals, comfort, or welfare of persons residing or working in or adjacent to the neighborhood of such use; and will not be detrimental to the properties or improvements in the vicinity or to the general welfare of the city. The medical office use is consistent with the Administrative, Professional and Financial Commercial General Plan Land Use designation and the purpose of the Santa Ana Heights (Business Park) Speck Plan. The proposed use office development is located in an existing office building along a portion of Birch Street developed with similar sized office buildings. The proposed use provides the required parking and only minor peak hour trip increases are projected. The operational characteristics and function of the proposed medical office use will be located entirely within the building. The proposal is for professional medical office uses that will have typical business hours and will not 0 Birch Medical Office Center April 21, 2005 Page 5 function as a clinic or emergency medical facility. Although not entirely occupied, the existing office building has not proven to be detrimental to the surrounding area or the City, nor is it anticipated that the proposed use will be detrimental. 3. That the proposed use will comply with the provisions of this code, including any specific condition required for the proposed use in the district in which it would be located. Medical office uses are permitted in the Santa Ana Heights Specific Plan (Business Park) district with the approval of a Use Permit. The project has been reviewed and conditioned to ensure that conflicts with surrounding land uses are minimized or eliminated to the greatest extent possible. Additionally, the project adheres to all applicable development regulations and will provide the minimum required parking. Given that the proposed location is in an existing conforming building, staff believes the findings to approve the medical office use can be made and recommended conditions of approval have been included in the draft resolution. Traffic Study The traffic study identifies the potential traffic and circulation impacts associated with the proposed development. The project is forecast to open later this year. Therefore the analysis has been conducted for the year 2006. The study analyzed the conversion of 18,885 square feet of the existing office building to a medical office use. The study concluded that the conversion will result in 680 new average daily trips above the existing general office use. Of these, 20 new AM peak hour trips and 59 new PM peak hour trips will be generated. The study evaluated eleven (11) intersections with potential impacts analyzed using the methodology required by the TPO. The City considers Level of Service D (LOS) as the upper limit of satisfactory operations for intersections. Mitigation is required for any intersection where project traffic causes the intersection to deteriorate from LOS D to LOS E. If an intersection is operating at LOS E or worse in the baseline condition, project impact occurs when the project- generated traffic increases the ICU (Intersection Capacity Utilization) by 0.01 or more. The project is forecast to contribute one percent or more to the traffic volume at three intersections: • Birch Street and Bristol Street • Birch Street and Bristol Street North • MacArthur Boulevard and Birch Street 1 Birch Medical Office Center April 21, 2005 Page 6 The other eight intersections were omitted from further ICU analysis as they did not meet the One Percent Test per the TPO. The ICU analysis of these three intersections concludes that the three intersections continue to operate at LOS B or better during both the morning and evening peak hours, and, therefore, no mitigation is required. The traffic study also performed a cumulative analysis that includes background traffic, approved and cumulative projects. The City of Newport Beach identified traffic growth from 11 approved and reasonably foreseeable projects that are anticipated for completion within the next few years. As with the TPO analysis, the proposed project did not pass the 1% test at the three intersections previously mentioned. The subsequent ICU analysis determined that the proposed project would have no marginal impact on those intersection and they will continue to operate at LOS B. Santa Ana Heights Project Advisory Committee (PAC) The Santa Ana Height PAC provided comments on the proposed plan that indicate that the conversion of the office space to medical office is acceptable if the project provides required parking. Environmental Review This project has been reviewed and it has been determined that it is categorically exempt from the requirements of the California Environmental Quality Act under Class 1 (Existing Facilities). This exemption covers interior alterations to existing private buildings. The interior alterations proposed and parking lot changes at the property are minor and the site has no significant environmental resources that would be impacted by the construction and operation of the project. Public Notice Notice of this hearing was published in the Daily Pilot, mailed to property owners within 300 feet of the property (excluding roads and waterways) and posted at the site a minimum of 10 days in advance of this hearing consistent with the Municipal Code. Additionally, the item appeared upon the agenda for this meeting, which was posted at City Hall and on the city website. 0 Prepared by: Submitted by: Birch Medical Office Center April 21, 2005 Page 7 4:�n c [ J CIYj Gregg B.

WHEREAS, an application was filed by Birch Medical Office Center regarding a property located at 20162 Birch Street requesting approval of Use Permit No. 2004 -046 to convert a portion of an existing office building to be used for medical office uses and approval of Traffic Study No. 2004 -006 pursuant to the Traffic Phasing Ordinance. WHEREAS, a public hearing was held on April 21, 2005 in the City Hall Council Chambers, 3300 Newport Boulevard, Newport Beach, California. A notice of time, place and purpose of the aforesaid meeting was given. Evidence, both written and oral, was presented to and considered by the Planning Commission at this meeting. Now, therefore the Planning Commission hereby resolves as follows: Section No. 1: The Planning Commission makes the following findings: 1. The Land Use Element of the General Plan designates the site for Administrative, Professional and Financial. Medical office uses are permitted uses within this category. 2. The project will not be detrimental to the public health, safety, peace, comfort, or welfare of persons residing or working in or adjacent to the neighborhood of such use; and will not be detrimental to the properties or improvements in the vicinity or to the general welfare of the City for the following reasons: a. The proposed medical use is located in an area designated as Business Park by the Santa Ana Heights Specific Plan district, which is a professional business office designation. The existing office building was originally constructed in compliance with all applicable development regulations related to setbacks, building height, floor area, and has not proven to conflict with surrounding uses or proven inconsistent with the APF zoning district. Medical office uses are consistent with this zoning designation and it is not likely the use will prove inconsistent with the surrounding area. b. The medical office use is consistent with the Administrative, Professional and Financial Commercial General Plan Land Use designation and the purpose of the Santa Ana Heights (Business Park) Specific Plan. The office development is located in an existing office building along a portion of Birch Street developed with similar sized office buildings. The operational characteristics and function of the proposed medical office use will be located entirely within the building. The professional medical office uses will have typical business hours and will not function as a clinic or emergency medical facility. The existing office building has not proven to be detrimental to the surrounding area or the City, nor is it anticipated that the proposed use will be detrimental. City of Newport Beach Planning Commission Resolution No. _ Paoe 2 of 4 2. A traffic study, entitled Traffic Analysis for Birch Street Medical Office Conversion (Austin - Foust Associates, Inc. January 28, 2005), was prepared for the project in compliance with Chapter 15.40 of the Municipal Code (Traffic Phasing Ordinance). a. The. proposed office conversion of up to 18,855 square feet of medical office use is expected to generate 680 new daily trips with 20 new trips during the morning, and 59 new trips during the evening peak hour. b. The traffic study determined that the project will contribute less than a 1 % increase in traffic at eight (8) of the eleven (11) intersections examined and therefore no mitigation is required for those. c. The traffic study determined that the project will not cause the level of service to decline at the remaining three (3) intersections where there will be an increase of more than 1% in traffic volume based on the ICU Analysis, and therefore, no mitigation is required. 3. The project is exempt from environmental review pursuant to Section 15302 (Class 1) of the implementing guidelines of the California Environmental Quality Act. This exemption covers interior alterations to existing private buildings. The interior alterations and parking lot changes at the property are minor, and the site has no significant environmental resources that would be impacted by the construction and operation of the project.

Ii EXHIBIT NO. 2 Traffic Impact Analysis dated January 28, 2005 15 BIRCH STREET MEDICAL OFFICE CONVERSION TPO TRAFFIC ANALYSIS Prepared by: Austin-Foust Associates, Inc. 2020 North Tustin Avenue Santa Ana, California 92705 -7827 (714) 667 -0496 January 28, 2005 m BIRCH STREET MEDICAL OFFICE CONVERSION TPO TRAFFIC ANALYSIS This report summarizes an analysis performed for the proposed conversion of 18,885 square feet of existing general office space to medical office space at 20162 Birch Street in Newport Beach based on the City's Traffic Phasing Ordinance (TPO) methodology. In addition, this report summarizes the results of an analysis of cumulative conditions in compliance with California Environmental Quality Act (CEQA) requirements. PROJECT DESCRIPTION The existing office building at 20162 Birch Street consists of 31,500 square feet of general office space. The project consists of converting 18,885 square feet of existing general office space to medical office space. The project is located on the east side of Birch Street south of Bristol Street in the City of Newport Beach. Figure 1 illustrates the location of the project. Figure 2 illustrates the proposed site plan. TRIP GENERATION AND DISTRIBUTION The proposed project consists of the conversion of 18,885 square feet of existing general office space to medical office space. The increase in traffic generated by the proposed medical office space was added to the surrounding circulation system. Trip generation for the proposed project is summarized in Table 1. As this table indicates, the proposed project results in an increase of 680 new trips daily. During the AM peak hour there is an increase of 20 trips generated compared with the trip generation of the existing office space. During the PM peak hour the proposed project generates 59 new trips compared with the trip generation of the existing office space. Trip distribution of project - generated traffic onto the surrounding circulation system was determined from observed travel patterns in the vicinity of the project site as well as from locations and levels of development in relation to the subject property. The general distribution is illustrated in Figure 3. Project - generated trips were distributed to the circulation system according to these distribution patterns. Figure 4 illustrates AM peak hour project trips, and Figure 5 illustrates PM peak hour project trips. Birch Street Medical Office Coaversioa TPO 1 Austin -Foust Associates, Inc.

These intersections are: MacArthur Boulevard and Campus Drive Campus Drive/Irvine Avenue and Bristol Street North Campus Drive/Irvine Avenue and Bristol Street Irvine Avenue and Orchard Drive Irvine Avenue and Mesa Drive Irvine Avenue and University Drive MacArthur Boulevard and Birch Street Birch Street and Bristol Street North Birch Street and Bristol Street Jamboree Road and Bristol Street North Jamboree Road and Bristol Street Existing (2004) peak hour intersection volumes were provided by City Staff. An ambient growth rate of 1.0 percent per year was added to the existing volumes on MacArthur Boulevard, Irvine Avenue, and Jamboree Road. Construction of the project is assumed to be complete in 2005; therefore, the study year is 2006. Traffic generated by approved projects in the study area, obtained from City Staff, were added to the existing peak hour volumes to obtain year 2006 background peak hour volumes for the intersections prior to the addition of project - generated traffic. Table 2 summarizes the approved projects included in this analysis. Background- plus - project peak hour volumes were obtained by adding the project - generated peak hour intersection volumes presented above to the existing- plus - regional growth- plus- approved projects peak hour volumes. The TPO analysis consists of a one percent analysis and an intersection capacity utilization (ICU) analysis at each study intersection. The one percent analysis compares the proposed project traffic with projected background peak hour volumes. To pass the one percent analysis, peak hour traffic from the proposed project must be less than one percent of the projected background peak hour traffic on each leg 1 of the intersection. If the proposed project passes the one percent analysis, then the ICU analysis is not l Birch Street Medical Office Conversion TPO 8 Austin -Foust Associates, Inc.

Traffic Analysis 017075tpt.doc required and no further analysis is necessary. If the proposed project does not pass the one percent t analysis, then the ICU analysis must be performed for the intersection which fails to pass the one percent I - test. i . Table 3 summarizes the results of the one percent analysis (the one percent analysis sheets are ,i included in the appendix). As this table indicates, the proposed project does not pass the one percent analysis at two study intersections during the AM and PM peak hour; therefore, an ICU analysis is I ' required for the intersections of Birch Street and Bristol Street North and Birch Street and Bristol Street. An ICU analysis was performed for the two intersections which did not pass the one percent test. Existing lane configurations were assumed, and a capacity of 1,600 vph per lane with no clearance factor was utilized. Table 4 summarizes the existing, background, and background- plus - project ICU values l during the AM and PM peak hours (actual ICU calculation sheets are included in the appendix). As the ICU summary table indicates, the project will have no marginal impact on the intersections of Birch Street and Bristol Street North and Birch Street and Bristol Street which will operate at level of service (LOS) `B" or better during the AM and PM peak hours. The project has no marginal impact on the study intersections, and no mitigation is required. . CUMULATIVE CONDITIONS ANALYSIS City Staff provided a list of I1 known but not approved projects for use in a cumulative conditions analysis. These cumulative projects are summarized in Table 5. Trip generation and distribution for each cumulative project was also provided by City Staff. The peak hour cumulative intersection volumes were added to the background volumes presented earlier, then project - generated traffic was compared to one percent of the background - plus - cumulative traffic. The proposed project does not pass the one percent test at the two study intersections identified above; therefore, an ICU analysis is required at these study intersections. The results of the cumulative ICU analysis are summarized in Table 6 (actual ICU calculation sheets are included in the appendix). As the cumulative ICU table indicates, the proposed project will have no marginal impact on the study intersections which continue to operate at LOS `B" or better, and no mitigation is required.

Birch Street is a four -lane street with a two -way left -turn lane in the vicinity of the project site. Project traffic has full access to Birch Street from the project driveway. 1 . The project will provide 122 parking spaces on -site, including five handicapped parking spaces. . The City parking requirement is one space per 250 square feet of office space, which results in 122 spaces for the entire site. The project will provide the required number of parking spaces on -site. Two -way circulation with 90 -degree parking is provided in the parking lot. The site plan indicates that parking spaces vary from 16 feet to 18 feet deep with a width of nine feet. The drive aisles vary from 24 feet to 25 rh feet. The City Municipal Code specifies that the minimum length of parking spaces is 17 feet with a minimum width of 8 t/2 feet and a minimum drive aisle width of 26 feet. The parking plan should be redesigned to provide the minimum parking space dimensions. A delivery truck loading area should be shown on the site plan. Deliveries to medical office buildings tend to be more frequent than deliveries to general office buildings, and a specified loading zone should be indicated on the site plan. CONCLUSIONS The proposed project, consisting of the conversion of 18,885 square feet of existing general office space out of 31,500 square feet of existing general office space to medical office space, will generate 680 more daily trips than is currently being generated by the site, and 20 more AM peak hour trips and 59 more PM peak hour trips than existing uses. The marginal impact of project traffic on the street system was determined at 11 intersections in the vicinity. Two of the 11 intersections did not pass the City's one percent analysis; however, the project had no marginal impact on the ICU values at these two intersections, which will continue to operate at level of service (LOS) `B" or better during the AM and PM peak hours. Consequently, the proposed project has no significant impact on the study intersections, and no additional intersection improvements are required. The impact of traffic from known but not approved projects was included in a cumulative conditions analysis. Under cumulative conditions, the project passed the City's one percent test at all but Birch street Medical Office Conversion TPO 15 Austin -Foust Associates, Inc. Traffic Analysis 017075rpt.doc 41 two study intersections. However, the project had no marginal impact on the ICU values at any of these two intersections during the AM or PM peak hour. Therefore, the proposed project has no significant impact on the study intersections under cumulative conditions, and no intersection mitigation measures are required. DEFINITIONS Certain terms used throughout this report are defined below to clarify their intended meaning: ADT Average Daily Traffic. Generally used to measure the total two - directional traffic volumes passing a given point on a roadway. DU Dwelling Unit. Used in quantifying residential land use. ICU Intersection Capacity Utilization. A measure of the volume to capacity ratio for an intersection. Typically used to determine the peak hour level of service for a given set of intersection volumes. LOS Level of Service. A scale used to evaluate circulation system performance based on intersection ICU values or volume/capacity ratios of arterial segments. Peak Hour This refers to the hour during the AM peak period (typically 7 AM - 9 AM) or the PM peak period (typically 3 PM - 6 PM) in which the greatest number of vehicle trips are generated by a given land use or are traveling on a given roadway. TSF Thousand Square Feet. Used in quantifying non - residential land uses, and refers to building floor area. Vic Volume to Capacity Ratio. This is typically used to describe the percentage of capacity utilized by existing or projected traffic on a segment of an arterial or intersection. VPH Vehicles Per Hour. Used for roadway volumes (counts or forecasts) and trip generation estimates. Measures the number of vehicles in a one hour period, typically the AM or PM peak hour.

BOX 1768, NEWPORT BEACH, CA 92659 -1768 (949) 644 -3311 MEMORANDUM TO: Gregg Ramirez Planning Department FROM: David Keely Traffic Engin i g DATE: April 13, 2005 SUBJECT: Birch Street Medical Office Conversion TPO — Supplemental Analysis This memorandum provides supplemental traffic analysis for the proposed Birch Street Medical Office conversion project located at 20162 Birch Street. The final traffic study, dated January 28, 2005, was prepared by Austin Foust Associates, Inc. Table 3 of the study summarizes the results of the One Percent Analysis. The TPO study identified the intersections of Birch Street/Bristol Street North and Birch Street/Bristol Street did not pass the one percent test. To pass the one percent test, peak hour traffic from the proposed project must be less than one percent of the projected background peak hour traffic on any leg of the intersections. If an intersection fails the One Percent analysis, further analysis is required utilizing the Intersection Capacity Utilization (ICU) methodology for all analysis scenarios (TPO and Cumulative Conditions). The results of the TPO indicated that the propose project was not forecast to cause any significant traffic related impacts. Additional review of the report revealed that the intersection of MacArthur Boulevard /Birch Street also fails the One Percent analysis during the p.m. peak hour. Therefore, additional ICU analysis of MacArthur Boulevard /Birch Street is required for TPO and Cumulative Conditions. Table 1 summarizes the Level of Service ranges. Table 2 summarizes the ICU analysis for the additional intersection under TPO analysis conditions (Approved Projects Conditions). Table 3 summarizes the ICU analysis for the additional intersection under Cumulative Conditions. icu analysis worksheets are provided in Attachment A. 4( Table 1 Level of Service Summary LOS ICU A 0.00 -0.60 B 0.61 -0.70 C 0.71 -0.80 D 0.81 -0.90 E 0.91 -1.00 F 1.01 & u Table 2 ICU Analysis S mmary TPO Conditions Table 3 ICU Analysis Summary Cumulative Conditions Existing roved Projects Approved Projects + Project Intersection AM PM AM PM AM PM MacArthur /Birch 0.38 0.48 0.39 0.48 0.39 0.48 Table 3 ICU Analysis Summary Cumulative Conditions As shown in Table 2 and 3, the intersection of MacArthur Boulevard /Birch Street intersection if forecast to operate at LOS A under all analysis scenarios.
