Diamond Bar Boulevard Building Diamond Bar, California Dear Mr. Zelefsky: As requested, Linscott, Law & Greenspan, Engineers (LLG) is pleased to submit the findings of a Parking Study Addendum we completed for the 750 N. Diamond Bar Boulevard (DBB) Building, located in the City of Diamond Bar. This letter report supplements our prior study dated August 8, 2018 to further validate the adequacy of on-site parking with the conversion of office-designated floor area to medical office space (herein after referred to as Project) as well as address the comments/concerns from adjacent property owners regarding potential parking intrusion by the Project. The existing building consists of general office, medical office, medical lab, bank, and storage uses, totaling 35,687 square feet (SF). As currently envisioned, the applicant/owner of the building proposes to convert 5,272 SF of office space within four (4) suites to medical office uses, plus add 1,190 SF of retail pharmacy space in place of office space. It should be noted that of the 5,272 SF of office space to be converted to medical office use, 2,771 SF of office space is currently occupied in Suites 222 and 222a, and the remaining 2,501 SF is currently vacant in Suites 224 and 228. Based on a review of the Project site plan prepared by Primior, the on-site parking supply would be increased from an existing total of 102 spaces to a proposed total of 119 spaces. Therefore, the Project’s proposed parking supply of 119 spaces was utilized as the proposed future parking supply for the DBB Building Project. This Parking Study Addendum evaluates the Project’s parking requirements based on the City of Diamond Bar Municipal Code, application of the shared parking Mr. Howard Zelefsky November 7, 2019 Page 2 3839 -Parking Study Addendum 11-07-2019N:\3800\2173839 - 750 N.

The study focused on the following:  Validation of existing parking spaces on the site (i.e. visitor, short-term parking, handicapped parking, reserved, etc.)  Calculates the Code-based parking requirements for the existing and proposed mix of uses/tenants for the DBB Building based on the application of City Code parking ratios.  Collection of existing parking demand surveys of the DBB Building over a three- day period to establish actual “shared” parking peak parking requirements for the current mix of office and medical office tenants, inclusive of potential parking intrusion by the Project at adjacent properties to the immediate north and immediate south.  Estimates future parking demands for the DBB Building by utilizing existing parking survey data, proposed tenant mix and ULI rates.  Compares survey plus shared parking demand against the existing/future parking supply, in order to identify any potential, operational surplus or deficiency in parking supply upon implementation of the Project. Our method of analysis, findings, and conclusions are described in detail in the following sections of this report. PROJECT DESCRIPTION The Project is an existing medical office/professional office building located at 750 N. Diamond Bar Boulevard. The existing building has a total of 35,387 square-feet (SF) of floor area on two levels. Currently, a total of 102 parking spaces are now provided at the subject property. Figure 1 presents an aerial map of the DBB Building, as well as the adjoining buildings. Figure 2-1 presents an existing site plan for the DBB Building, inclusive of a breakdown of the existing on-site parking supply. Table 1 presents the existing development summary and tenant mix, as well as the proposed Project and tenant mix for the DBB Building. The current tenant mix, which occupies 31,996 SF, consists of 15,552 SF of office space, 11,634 SF of medical office uses, a 1,343 SF medical lab, a 2,755 SF credit union, and 712 SF of storage space. The remaining floor area of 3,691 SF is a vacant office floor area. Mr. Howard Zelefsky November 7, 2019 Page 3 3839 -Parking Study Addendum 11-07-2019N:\3800\2173839 - 750 N. Diamond Bar Blvd Parking, Diamond Bar\2019 Parking Study Addendum\Report\3839 -Parking Study Addendum 11-07-2019.docx A summary of the information provided in Table 1 is provided below. As shown the applicant/owner of the building proposes to increase the medical office uses from 11,634 SF to 16,906 SF, plus add 1,190 SF of retail pharmacy space in place of office space. With the Project, the existing office floor area would be reduced from 19,243 SF to 12,781 SF. Figure 2-2 presents the proposed site plan for the Project and associated parking facilities, prepared by Primior. Review of Figure 2-2 shows that with the relocation/restriping of handicap stalls and the construction of new stalls on the eastern-most portion of the site would result in a net total of 17 new parking stalls. Therefore, the on-site parking supply would be increased to 119 spaces, which would meet the requirements of the City’s Municipal Code, as shown below and in Table 1.

Parking ratios from the City Code relevant to the project site in either its current or proposed development pattern are as follows:  Office, administrative, corporate: 1 space/400 square-feet (SF) gross floor area (GFA)  Clinics, medical/dental offices: 1 space/250 SF GFA Mr. Howard Zelefsky November 7, 2019 Page 4 3839 -Parking Study Addendum 11-07-2019N:\3800\2173839 - 750 N. Diamond Bar Blvd Parking, Diamond Bar\2019 Parking Study Addendum\Report\3839 -Parking Study Addendum 11-07-2019.docx  General retail: 1 space/250 SF GFA  Banks and financial services: 1 space/300 SF GFA Under the existing land use mix, the City Code requirement totals 109 spaces, which corresponds to a Code-based deficiency of 7 spaces when compared against the existing supply of 102 spaces for the DBB Building. The City Code requirement for the Project totals 119 spaces. Compared against the 119-space supply, the 119-space Code requirement would exactly match the supply. Based on the above findings, the City Code-based parking requirements for the existing land use mix, and the proposed Project would be adequately served by the future on-site parking supply for the DBB Building (119 spaces). To validate the adequacy of the proposed parking supply of 119 spaces at the DBB Building with the existing mix of uses/tenants and the proposed Project as summarized in Table 1, a parking demand has been prepared based using actual field-studied demands (parking surveys) of the subject property. The following section calculates the parking requirements for the DBB Building based on actual field-studied demands (parking surveys) and application of the current shared parking methodology outlined in ULI Shared Parking, 2nd Edition. PARKING DEMAND ANALYSIS This section evaluates the actual field study data for the existing tenancies in combination with a forecast for the existing floor area vacancies, inclusive of the proposed Project, which utilizes the current Urban Land Institute (ULI) shared parking methodology. Given the DBB Building is an established office development, the collection of parking survey data provides support of the “shared” parking demands of the existing tenant mix. As noted earlier, this Parking Study Addendum estimates future parking demands for the DBB Building by utilizing existing parking survey data to establish the center’s existing peak parking demand, illustrate the sharing of a common parking supply by a mix of office and medical office uses, and via the use of the shared parking methodology, forecast the hourly demand for the proposed tenant mix, which includes additional medical office floor area and a proposed pharmacy. Observed Parking Demand Consistent with study parameters of the approved scope of work for this addendum, field studies of actual parking demand at DBB Building were undertaken to evaluate Mr. Howard Zelefsky November 7, 2019 Page 5 3839 -Parking Study Addendum 11-07-2019N:\3800\2173839 - 750 N. Diamond Bar Blvd Parking, Diamond Bar\2019 Parking Study Addendum\Report\3839 -Parking Study Addendum 11-07-2019.docx current parking conditions and to develop insights as to potential parking intrusion into the adjacent properties, as well as identify duration of vehicles parked on-site. To establish the existing (baseline) shared parking demand of the existing uses at DBB Building, hourly surveys of actual parking demand were conducted at the site from 6:00 AM – 6:00 PM on Monday, October 7, 2019, Tuesday, October 8, 2019, and Wednesday, October 9, 2019. As a supplement, pedestrian affinity observations were collected to determine the potential for parking intrusion from the northern/southern off-site adjacent lots1 (i.e. patrons of the Project parking off-site in adjacent lots and walking to the Project facilities). From these supplemental observations, “off-site parking demand” associated with the DBB building was determined, and therefore was added to the on- site parking demand. The parking surveys, conducted by NDS under the direction of LLG, consisted of counting the number of parked vehicles within the entire DBB Building lot and keeping track of the duration that were observed parked on-site. This information reflects a more precise parking demand for the DBB Building, specifically, the shared parking demand associated with 31,996 SF of occupied floor area (89.7% occupancy). Appendix A contains the detailed survey data with a summary of the data presented in the following tables noted below, as well as supplemental pedestrian affinity studies, and parking duration studies. A summary of the results of the parking surveys that were performed at the DBB Building on a recent Monday, Tuesday and Wednesday is summarized in Tables 2, 3, and 4, respectively. These tables present the parking demand at the DBB Building for each hour during the count dates, and compared observed demand against existing on-site parking supply of 102 spaces. A review of these tables indicate a total peak demand of 83 spaces (81% utilization) occurred on Wednesday at 11:00 AM (See Table 4), and was comprised of 83 occupied spaces for the DBB Building (on site and those observed parked in adjacent properties. Comparing the DBB Building’s 83- space peak demand against the existing supply of 102 spaces corresponds to an observed surplus of 19 spaces. A review of Tables 2 and 3 indicate that the peak parking demand observed at the DBB Building was less on Monday, October 7, 2019 and totaled 70 vehicles (69% utilization) at 11:00 PM, whereas the peak demand on Tuesday, October 8, 2019 was 1 For this analysis, the parking demand observed to park in adjacent properties to the north and to the south during the parking demand studies conducted on October 7, 8 and 9, 2019 were presumed to be generated by DBB Building. Mr. Howard Zelefsky November 7, 2019 Page 6 3839 -Parking Study Addendum 11-07-2019N:\3800\2173839 - 750 N. Diamond Bar Blvd Parking, Diamond Bar\2019 Parking Study Addendum\Report\3839 -Parking Study Addendum 11-07-2019.docx less than Wednesday as well and totaled 70 vehicles (69% utilization) at 12:00 PM, respectively. It is important to note that based on City code, the existing occupied uses, as shown below, would require 100 spaces whereas the existing observed peak demand for the current tenant mix totaled 83 spaces. EXISTING OCCUPIED AND VACANT SF CODE PARKING CALCULATIONS Description Existing Occupied SF Ratio Requirement General Office 15,552 SF 1 sp/400 SF 39 spaces Medical Office 11,634 SF 1 sp/250 SF 47 spaces Medical Lab 1,343 SF 1 sp/300 SF 5 spaces Bank 2,755 SF 1 sp/300 SF 9 spaces Storage 712 SF ---- 0 spaces Subtotal 31.996 SF 100 spaces Office (Vacant) 3,691 SF 1 sp/400 SF 9 spaces Total 35,687 SF 109 spaces Forecast Parking Demand Based on the results of actual parking demand studies of the DBB Building, it was established that the peak parking demand for the current occupied floor area and mix of tenants totaled 83 parking spaces (See Table 4 at 11:00 AM). Conservatively, without adjustment to account for the conversion of existing occupied office floor area of 2,771 SF, the code parking requirements associated with the addition of 5,272 SF of medical office space and a 1,190 SF pharmacy amounts to 21 spaces and 5 spaces, respectively for a total of 26 spaces. PROPOSED PROJECT SF CODE PARKING CALCULATIONS Description Proposed Project SF Ratio Requirement Medical Office 5,272 SF 1 sp/250 SF 21 spaces Pharmacy 1,190 SF 1 sp/250 SF 5 spaces Subtotal 6,462 SF 26 spaces Existing Peak Demand Occupied SF Wed, 10/9 at 11 am 83 spaces Total 35,687 SF 109 spaces This total, when added to the observed peak demand of 83 spaces results in a forecast peak parking demand for the DBB Building of 109 spaces (83 + 26) upon completion of the Project. Compared against the proposed 119-space supply, the forecast 109- space peak parking demand would result in a surplus of 10 spaces (8.4% contingency supply. Mr. Howard Zelefsky November 7, 2019 Page 7 3839 -Parking Study Addendum 11-07-2019N:\3800\2173839 - 750 N. Diamond Bar Blvd Parking, Diamond Bar\2019 Parking Study Addendum\Report\3839 -Parking Study Addendum 11-07-2019.docx Shared Parking Demand Assessment The Shared Parking methodology was applied in estimating the parking needs of the Project. This goes beyond simply calculating the City Code requirement, and looks at the operational demand picture within the actual physical setting. The objective of this Shared Parking analysis is to estimate the peak parking requirements for the various components of the Project based upon their combined parking demand patterns. In order to determine the most appropriate peak-parking requirement for the DBB Building with the proposed Project, utilization of the actual survey data for the existing land uses has been combined with ULI shared parking techniques applied to the proposed medical office uses and pharmacy retail floor area. The analytical procedures in a Shared Parking analysis are well documented in the Urban Land Institute’s (ULI’s) Shared Parking (First and Second Editions) publication. As part of the shared parking calculations, the Project’s shared parking requirements were added to the existing parking demand observed (based on parking demand field studies/surveys that were performed), and compares the resultant shared parking demand for the Project against the future parking supply, in order to identify any potential parking surplus or deficiency. The hourly parking demand profiles (expressed in percent of peak demand) utilized in this analysis and applied to the proposed Project at DBB Building are based on profiles developed by the Urban Land Institute (ULI) and published in Shared Parking, 2nd Edition, unless otherwise noted. For the Project’s proposed Pharmacy-use, the code requirement for general retail of 1 space per 250 SF was utilized and the ULI retail use profiles are applied directly. The resulting profiles represent the most likely hourly parking demand profile, and are applied to the City’s retail parking ratio of 1 space per 250 SF. From Table 1, a total of 1,190 SF of Pharmacy floor area is proposed. For medical office uses, the parking profile in the ULI publication was used and applied to the City’s Parking Code ratio of 1 space per 250 SF to forecast its weekday hourly demand. Based on the proposed Project, the applicant/owner of the building proposes to convert 5,272 SF of office space within four (4) suites to medical office uses. Since the existing parking surveys were conducted while 2,771 SF of office space was currently occupied in Suites 222 and 222a, adjustments were made to the existing parking surveys due to the proposed Project renovating and reoccupying these uses Mr. Howard Zelefsky November 7, 2019 Page 8 3839 -Parking Study Addendum 11-07-2019N:\3800\2173839 - 750 N. Diamond Bar Blvd Parking, Diamond Bar\2019 Parking Study Addendum\Report\3839 -Parking Study Addendum 11-07-2019.docx with medical office use. A composite parking ratio was calculated for each day that counts were collected and ranged from 2.19 to 2.59 spaces per 1000 SF of GFA, which is in line with the City’s office parking ratio of 2.5 spaces per 1000 SF of GFA (1 space per 400 SF of GFA). In order to provide a conservative assessment, the minimum ratio of 2.19 spaces per 1000 SF was applied to the 2,771 SF existing office to be converted to medical office and the ULI office use profiles were applied directly. Shared Parking Demand Analysis Results Tables 5, 6 and 7 summarize the results of this approach and present the forecast parking demand for the vacant uses and the proposed Project for a weekday (Monday, Tuesday and Wednesday) based on the survey-shared parking methodology. Appendix B contains the overall shared parking analysis calculation worksheets for DBB Building for a weekday. Column (1) of Tables 5, 6 and 7 presents a summary of the weekday (Monday, Tuesday and Wednesday) parking survey data collected at the site for 31,996 SF of occupied floor area, as summarized in Tables 2, 3 and 4, respectively, while Column (2) summarizes the estimated hourly parking demand associated with 2,771 SF of existing occupied office space that would be renovated to accommodate the proposed Project. Columns (3) and (4) present the parking accumulation characteristics of the proposed medical office and pharmacy components of the Project, respectively, for the hours of 6:00 AM to 6:00 PM. Column (5) presents the expected joint-use parking demand for the entire site on an hourly basis, while Column (6) summarizes the hourly parking surplus/deficiency for the DBB Building when compared to the proposed parking supply of 119 spaces; the percentage surplus/deficiency is also noted in this column. Survey/Shared Parking Analysis Results Review of Tables 5, 6 and 7 show that the overall peak-parking requirement for the DBB Building during a weekday, assuming full occupancy and completion of the proposed Project, occurs on Wednesday at 11:00 AM and totals 102 spaces (See Table 7); the peak parking demand for Monday and Tuesday is less than that, and totals 89 spaces and 87 spaces, respectively (See Table 5 and Table 6). Based on a proposed parking supply of 119 spaces, a minimum surplus of 17 spaces on (14% contingency) a weekday is forecast during the peak hours. Mr. Howard Zelefsky November 7, 2019 Page 9 3839 -Parking Study Addendum 11-07-2019N:\3800\2173839 - 750 N. Diamond Bar Blvd Parking, Diamond Bar\2019 Parking Study Addendum\Report\3839 -Parking Study Addendum 11-07-2019.docx Figures 3, 4, and 5 graphically illustrate the weekday (Monday, Tuesday and Wednesday) hourly parking demand forecast for the Project, respectively. Each vacant land use component and its corresponding hourly Shared Parking demand for various mixes of uses, which were presented in Tables 5, 6, and 7, are depicted in these figures relative to a proposed parking supply of 119 spaces. A review of these figures indicates that the center’s proposed parking supply of 119 spaces will adequately accommodate the DBB Building’s weekday hourly demand based on the survey plus shared parking demand analysis. Survey/Shared Parking Analysis Conclusions Our findings above indicate that the proposed parking supply for the DBB Building would be adequate in meeting the overall future parking demand, inclusive of those associated with the Project, and that it would be reasonable and enforceable for all Project components to share the parking facilities. Furthermore, review of Tables 5, 6 and 7 indicate that excluding the parking demand credit associated with the removal and conversion of 2,771 SF of existing office to medical office-use would result in an overall peak-parking requirement for the DBB Building of 108 spaces on Wednesday at 11:00 AM (See Table 7). The peak parking demand for Monday and Tuesday would be less than that, and total 95 spaces and 93 spaces, respectively. Therefore, if no parking credits were to be applied for the center, the proposed parking supply of 119 spaces would still adequately accommodate the DBB Building’s hourly demand. To help manage parking demands of the existing and proposed tenants it is recommended that the Property Owner and/or Property Management Company consider implementation of a Parking Management Plan (PMP). Mr. Howard Zelefsky November 7, 2019 Page 10 3839 -Parking Study Addendum 11-07-2019N:\3800\2173839 - 750 N. Diamond Bar Blvd Parking, Diamond Bar\2019 Parking Study Addendum\Report\3839 -Parking Study Addendum 11-07-2019.docx PARKING MANAGEMENT PLAN This Parking Management Plan (PMP) outlines the proposed allocation of parking supply on site and key parking management strategies to maximize the availability of parking for customers/visitors and employees of the DBB Building. When the Property Owner/Property Management Company deems it necessary, the following key Parking Management Strategies could be implemented to minimize customer/employee disruption. PMP measures Specific PMP measures relative to the employee parking operation and short-term parking for customers/visitors are described below, and were developed based on the following objectives:  The PMP should identify where the office/medical office employees park within the site.  The PMP should identify where location of short-term parking spaces for customers/visitors to the bank, medical office, office, pharmacy-uses, etc. 1. The Property Owner/Property Management Company work with tenants of the center to implement an employee parking program, with the goal of providing convenient and accessible shopping experience for the customers/visitors of the building and to leave the most desirable parking spaces for use by customers/visitors. The location of designated employee parking spaces will be developed in collaboration between Property Owner/Property Management and the tenants. The employee parking spaces will be identified with a white or yellow circle. It is noted that these spaces will be open for customer use. 2. Property Owner/Property Management will work with tenants of the building to identify the need for “short term/time restricted spaces” on an as need basis, dependent on the needs of the proposed medical office and pharmacy uses. The short-term spaces may be used for “Patients/Visitors only”. The number and location of spaces will be determined by Property Owner/Property Management and the existing/potential tenants. 3. Property Owner/Property Management will work closely and inform with the tenants to ensure all parking demand associated with the DBB Building occurs on-site and eliminate parking intrusion in the adjacent properties. Property Owner/Property Management will work closely with the tenants to insure that both employees and property management work together to provide the best experience for the customers/visitors, as well as allowing the most desirable parking spaces to be accessed by the customers/visitors rather than the employees.   Mr. Howard Zelefsky November 7, 2019 Page 11 3839 -Parking Study Addendum 11-07-2019N:\3800\2173839 - 750 N. Diamond Bar Blvd Parking, Diamond Bar\2019 Parking Study Addendum\Report\3839 -Parking Study Addendum 11-07-2019.docx SUMMARY OF FINDINGS AND CONCLUSIONS 1. 750 N. Diamond Bar Boulevard (DBB) Building is an established professional office building that includes a tenant mix consisting of general office, medical office, medical lab, bank, and storage uses, totaling 35,687 square feet (SF). As currently envisioned, the applicant/owner of the building proposes to convert 5,272 SF of office space within four (4) suites to medical office uses, plus add 1,190 SF of retail pharmacy space in place of office space. Based on the Project site plan prepared by Primior, the on-site proposed parking supply would be increased from an existing 102 spaces to 119 spaces. 2. This Parking Study Addendum evaluates the existing tenancy condition as well as with full occupancy of the site with the proposed medical office and pharmacy uses using actual parking demand surveys. 3. Direct application of City parking codes to the existing and proposed mix of uses results in a total parking requirement of 119 parking spaces. When compared against the proposed parking supply of 119 spaces, the DBB Building satisfies the City’s parking code requirements. 4. To establish actual parking demand for the DBB Building, and identify potential parking intrusion into the adjacent properties, existing parking demand surveys of the subject property were conducted on three recent weekdays (Monday, October 7, 2019, Tuesday, October 8, 2019, and Wednesday, October 9, 2019). 5. The results of the parking demand surveys indicate that a total peak demand of 83 spaces occurred on Wednesday at 11:00 AM, inclusive of those observed parked in adjacent properties). Comparing the DBB Building’s 83-space peak demand against the existing supply of 102 spaces corresponds to an observed surplus of 19 spaces. This existing peak parking demand, when added to the 26- space code parking requirement of the Project, results in a forecast peak parking demand for the DBB Building of 109 spaces (83 + 26) upon completion of the Project. Compared against the proposed 119-space supply, the forecast 109- space peak parking demand would result in a surplus of 10 spaces (8.4% contingency supply. 6. A “blended” analysis of actual parking demand for existing occupancies that were based on a three-day survey of the Project site and the use of the shared parking approach indicates that the future minimum functional surplus at the DBB Building will be slightly greater. With additional medical space and a pharmacy, the resultant maximum or peak shared demand for the Project site is forecast to Mr. Howard Zelefsky November 7, 2019 Page 12 3839 -Parking Study Addendum 11-07-2019N:\3800\2173839 - 750 N. Diamond Bar Blvd Parking, Diamond Bar\2019 Parking Study Addendum\Report\3839 -Parking Study Addendum 11-07-2019.docx total 102 spaces, which translates to a surplus of 17 spaces when compared to a proposed parking supply of 119 spaces. 7. Based on the above findings, we conclude that based on the application of the shared parking approach, and on empirical study of existing parking demand, the parking needs of the DBB Building upon completion of the Project would be adequately served by the proposed parking supply. ● ● ● ● ● We appreciate the opportunity to provide this analysis.
