Re: West Berkeley Family Practice Traffic and Parking Study
Dear Ms. Rosencranz:
This letter presents our findings concerning the traffic operations and parking supply near the West Berkeley Family Practice (Project) site in Berkeley, California. The site is at 2031 Sixth Street in Berkeley, California and is the largest primary care site within the LifeLong Medical Care organization. Due to the tightly constrained size and configuration at the current site, the current clinic is finding that the conditions are compromising the provision of quality patient care and exacerbating waiting times.
To alleviate these issues, LifeLong Medical Care is preparing to expand the 11,737 square-foot facility by 7,982 square feet. This study’s purpose is to determine the impact on the traffic operations at the nearby intersection of University Avenue/Sixth Street, and to ensure that the parking supply available to the site is adequate to serve the estimated demand. This study was scoped in consultation with LifeLong Medical Care and planning and traffic engineering staff from the City of Berkeley.
PROJECT DESCRIPTION
The current Project site provides medical care for people of all ages, including pediatric and prenatal care, mental health care, drop-in clinics for children and adults, nurse advice, and health education classes. Currently the clinic is approximately 12,000 square feet and provides care to roughly 6,600 patients in 28,000 patient-visits per year. The clinic also has about 55 staff members on-site daily. With the proposed expansion, the clinic will be 19,717 square feet, with the ability to serve about 40,000 patient-visits per year. Approximately 73 staff members will be on-site daily. Construction is expected to begin in 2010, with move-in scheduled for the end of 2011.
The Project study area is shown on Figure 1. (All figures are attached at the end of the report.)
MODE CHOICE SURVEY
Two surveys, one for patients and one for staff, were prepared by Fehr & Peers and sent to LifeLong Medical Care for distribution at the Project site. Clinic staff conducted the survey over an eight-day period from July 13th to July 20th and received 206 patient responses and 47 staff responses. There was a 50 percent response rate from patients and an 80 percent response rate from staff. Sample surveys can be seen in the attachments.
Table 1 shows the mode choice of both patients and staff, and Table 2 summarizes where drivers parked their vehicles.

Over three-quarters of the patient-visits are currently by private automobile, many of which park in the clinic’s fourteen-space parking lot. About 80 percent of the staff drive alone, while others bike or walk; those who drive generally park on the street surrounding the clinic.
The staff surveys convey that over 90 percent of staff arrive and depart during the traditional AM and PM peak periods (7:00 AM to 9:00 AM and 4:00 PM to 6:00 PM).

TRAFFIC IMPACT ANALYSIS
Existing Traffic Conditions
One intersection was selected for the traffic analysis, based on the size of the Project and the current operating condition of the intersection: University Avenue and Sixth Street. For the purpose of this study, existing traffic volumes in the West Berkeley Circulation Master Plan: Draft Existing Conditions Report (October, 2007) were used. In the AM peak hour, the major traffic movements are along University Avenue moving through the intersection. In the PM peak hour, these movements are still substantial, but there are also heavy movements from the north and south turning west toward the Interstate 80/580 freeway.
Figure 2 shows the existing traffic volumes, geometry, and traffic control at the intersection.
Project Trip Generation To estimate current trip generation of the site, Fehr & Peers obtained data on the operating characteristics of the site, including yearly patient visits, daily staff on site, operating hours, and typical day-of-week distribution for patient visits, along with the results of the mode choice survey. Daily Trip Generation Person Trips To calculate the number of daily patient trips, the number of yearly patient trips (28,000) was reduced to weekly trips (539) and then to weekday trips. About 10 percent of the typical patient visits occur on the weekends, so 18 percent (90 percent divided by 5 days per week) of the weekly 539 patient visits were assumed to occur on a typical weekday – 97 visits per weekday. Dividing two times the total daily visits (to account for patients coming to and leaving the site) by the square footage results in a trip generation rate of roughly 16.5 daily patient-trips per thousand square feet (ksf). Furthermore, each of the 55 staff on-site each day also make two trips, creating an additional 110 trips each day, or 9.4 trips per ksf. Dividing the sum of the patient trips and staff trips by the square footage results in a trip generation rate of 25.9 daily person trips per ksf. Vehicle Trips The mode choice surveys indicate that vehicle trips comprise 82 percent of all patient trips and 83 percent of all staff trips, after accounting for trips made by transit, walking or biking, as well as carpooling, and drop-off trips, which amount to two vehicle trips per person trip (the technical appendix contains the calculation of the vehicle factors.) Applying the corresponding reduction factors of 18 percent for patients, and 17 percent for staff, to the daily person-trip generation, results in a final trip generation rate of 21.3 daily vehicle trips per ksf. Peak Hour Trip Generation Person-Trips Since patient visits are evenly distributed throughout the day, there are an estimated 20 patient trips during each peak hour. Based on survey data, less than half of the staff arrive and leave during the AM and PM peak commute hours, resulting in approximately 20 staff trips during the peak hour. Combining the patient and staff trips results in a peak hour trip generation rate of 3.4 peak hour person trips per ksf.

Ms. Nance Rosencranz October 8, 2009 Page 4 of 11
Vehicle Trips Applying the reduction factors to account for non-automobile modes results in a final peak hour vehicle trip generation rate of 2.8 peak hour trips per ksf. Comparison to Other Trip Generation Rate Sources In order to ensure that this rate is reasonable for the site, several sources were consulted. The Institute of Transportation Engineers’ (ITE) Trip Generation, 8th Edition contains rates for: hospital (code 610), clinic (code 630), and medical office building (MOB) (code 720). The daily rates range from 16.50 trips per ksf to 36.13 per ksf. These rates are supplemented by other studies Fehr & Peers has completed in Walnut Creek, Tracy, Oakland, Roseville, Palo Alto, and Hayward. These past studies show daily rates ranging from 13.31 to 40.71. (See Table 3).

Selected Trip Generation Rate It was decided that the ITE MOB rate, shown in bold in Table 3, should be used for the traffic analysis, because it is a standard rate supported by nationwide surveys, and is similar to the site-specific rate estimated by Fehr & Peers based on site characteristics. The ITE MOB average rate does not adjust for the size of the site; therefore, the linear regression equation provided in Trip Generation, 8th Edition was used instead. This equation was created using the same data that was used to calculate the average rate. The equation is as follows:
Daily Trips = 40.89 x (Square Footage) – 214.97
ATTACHMENT 6 ZAB 12-10-09 Page4of 36
Ms. Nance Rosencranz October 8, 2009 Page 5 of 11
Using the ITE equation for daily trips and the peak hour average rates for hourly trips results in 326 more trips throughout the day due to the project, 18 of which occur during the AM peak hour and 27 of which occur during the PM peak hour. As shown in Table 4, the ITE based peak hour trip generation is slightly higher than the trip generation based on Fehr & Peers’ site-specific rates. Thus, the traffic operations analysis based on ITE rates for the PM peak hour is more conservative.

Trip Distribution and Assignment This traffic analysis conservatively assumes that all new project trips would travel through the Sixth Street and University Avenue intersection. The trips were proportioned based on the current movements to and from the south approach of the intersection. The resulting Project trip turning movements are shown on Figure 2. Intersection Level of Service
Traffic operations at the Sixth Street and University Avenue intersection were analyzed using the Synchro 7.0 software program. Synchro is based on procedures outlined in the Transportation Research Board's 2000 Highway Capacity Manual (HCM). The analysis results include a descriptive term known as level of service (LOS). LOS is a measure of traffic operating conditions, which varies from LOS A (indicating free flow traffic conditions with little or no delay) to LOS F (representing over-saturated conditions where traffic flows exceed design capacity resulting in long queues and delays). These grades represent the perspective of drivers and are an indication of the comfort and convenience associated with driving.
The LOS is determined differently depending on the type of control at the intersection. For signalized intersections, the LOS rating is based on the weighted average control delay of all movements measured in seconds per vehicle. Peak hour traffic volumes, lane configurations, and signal timing plans are used as inputs in the LOS calculations. Table 5 summarizes the relationship between the average control delay per vehicle and LOS for signalized and unsignalized intersections.

Table 6 shows the LOS results for the existing, near-term, and cumulative cases analyzed. The results are discussed below. Existing and Existing Plus Project Cases AM and PM peak hour intersection turning movements published in the West Berkeley Circulation Master Plan: Draft Existing Conditions Report were used to represent existing conditions. Using these volumes, the intersection currently operates at LOS D in the AM peak hour and LOS F in the PM peak hour. Project-generated traffic was added to the existing volumes to estimate intersection turning volumes after the completion of the project. With the project, the levels of service do not change and the average delay increases by approximately one second during both peak hours. (Refer to Figure 2 and Table 6). Near-Term and Near-Term Plus Project Cases The Project is estimated to be completed in 2012. To determine the background volumes for this scenario, the existing traffic volumes were adjusted to reflect estimated regional traffic growth, as well as to reflect traffic from recently approved local projects. For the regional growth, the existing volumes were increased by two percent, reflecting four years of one-half percent growth per year. For the traffic from local projects, a list of recently approved projects, along with the traffic studies prepared for those projects, was supplied by the City of Berkeley. Fehr & Peers determined the trip assignment from each project to the University/Sixth intersection, and added it to the intersection’s turning movements. Figure 2 shows the resulting traffic volumes. The technical appendix contains the specific traffic added from each project. Using the resulting Near-Term volumes, the intersection is projected to continue to operate at LOS D in the AM peak hour and LOS F in the PM peak hour. With the addition of Project traffic, the levels of service do not change and the average delay increases by approximately one second during the PM peak hour only. (Refer to Figure 2 and Table 6).

Cumulative and Cumulative Plus Project Cases AM and PM peak hour intersection turning movements published in the West Berkeley Circulation Master Plan: Future Conditions Report were used for cumulative conditions. Using these volumes, the intersection is projected to operate at LOS E in the AM peak hour and LOS F in the PM peak hour. With the addition of project traffic, the levels of service do not change and the average delay increases by approximately one second during both peak hours. (Refer to figure 3 and Table 6).

Traffic Impact Significance Determination The significance criteria established by the City of Berkeley in Guidelines for Development of Transportation Impact Reports for signalized intersections are used to identify potential significant impacts. The following criteria are used to determine if the proposed project would cause a significant impact: A significant traffic-related impact would occur at signalized intersections if the addition of project traffic results in:
Intersection operations degrade from LOS D to LOS E or worse and more than a 2-second increase in delay; or
ATTACHMENT 6 ZAB 12-10-09 Page7of 36
Ms. Nance Rosencranz October 8, 2009 Page 8 of 11
More than a 3-second increase in delay at intersections operating at LOS E without and with the project; or
Intersection operations degrade from LOS E to LOS F and more than a 3-second increase in delay; or
At intersections operating at LOS F without the project, a change in the volume-to-capacity (v/c) ratio of more than 0.01.
Based on these criteria, the Project does not result in a significant impact on the intersection under any scenario, and mitigation is not needed. The Synchro worksheets used to complete this analysis are provided in the attachments.
PARKING IMPACT ANALYSIS
The following discussion summarizes the existing parking supply and demand, both in the Project site parking lot and on surrounding streets; estimates the current and future parking demand at the peak, mid-day period; discusses the impact of the Project on area parking supply; and discusses the potential mitigations for the Project’s parking deficit.
Existing Parking Supply and Occupancy
Fehr & Peers surveyed the streets within a one-to-two-block radius of the clinic to catalog the parking supply in the area, and the demand for parking during the clinic’s peak parking period, mid-afternoon. The area was surveyed on Wednesday, June 3, 2009 between 1:00 PM and 2:00 PM The following streets were included in the survey:
University Avenue between Fifth Street and Seventh Street
Addison Street between Fourth Street and Eighth Street
Allston Way between Fifth Street and Seventh Street
Fifth Street between University Avenue and Allston Way
Sixth Street between University Avenue and Bancroft Way
Seventh Street between University Avenue and Allston Way
Also included in the survey were the 14 parking spaces currently in the WBFP parking lot.
Figure 4 shows the parking available in the area, as well as the restrictions on certain spaces, including metered spaces, spaces for the physically disabled, and time restricted spaces. Figure 5 shows the number of spaces available on each block, as well as the number occupied at the time of the survey. Table A-1, included in the attachments, provides these quantities and enumerates the restrictions for each block.
Overall, 345 parking spaces are provided in the study area, and about 292 were occupied during the survey. All 14 of the clinic’s current spaces were occupied during the data collection. Of the 53 unoccupied spaces, 23 were restricted by either meters or disabled parking signs. Thus, about 30 unrestricted spaces in the immediate area surrounding the site are available during what is estimated to be the peak period of demand for parking at the site. During this period, 90 percent of the unrestricted spaces were occupied.
ATTACHMENT 6 ZAB 12-10-09 Page8of 36

Project Parking Demand
The following discussion is summarized in Table 7.
Site-Specific Estimate
To approximate demand for the current site, we estimated that the maximum number of patients that would need to park in the area at a certain time would be twice the average of the hourly rate for patient arrivals. This conservatively assumes that the average patient stay is two hours long, although survey data shows that the average duration of a patient’s visit is between 30 and 90 minutes. There are, on average, 97 patient visits per day arriving between 8:00 AM and 6:00 PM, resulting in roughly 10 patient visits per hour. Considering that roughly 64 percent of patients drive and park in the area, based on the travel mode survey, the estimated patient parking demand is 13 spaces. Considering that 79 percent of staff drive and park in the area, the 55 staff members would require 44 parking spaces. Thus, we estimate that currently the clinic’s peak parking demand is 57 parking spaces.
With the projections of 40,000 yearly visits and 73 full-time staff on site, the same methodology results in 138 patient visits per day, 18 of whom will need parking during the peak period, as well as 58 of the 73 staff members, totaling 76 parking spaces for which there will be demand. Thus, the estimated project parking demand is 19 spaces higher than the estimated current parking demand (76 future spaces minus 57 existing spaces).
City Code Requirement
Chapter 23, Section E.64 of the City of Berkeley Municipal Code and Zoning Ordinance states that “[t]he district minimum standard parking requirement for commercial floor area is two spaces per 1,000 square feet of gross floor area” unless the land use meets a special criterion, for which there are different requirements. For medical practitioner offices, the requirement is one space per 300 ksf, or 3.3 spaces per ksf. These requirements are applicable based on the standards of the West Berkeley Commercial District, which borders but does not include the site based on Plate 4 of the Official Zoning Maps in Chapter 23, Section F. According to these maps, the site is labeled as “R-4,” or part of the Multi-Family Residential District. The same specific-use requirements apply to hospitals and medical offices, but the district minimum for the West Berkeley Commercial District does not apply to the Multi-Family Residential District.
Currently the clinic provides 14 parking spaces on-site. By the standards for the medical practitioner office use, the clinic should provide 39 parking spaces (11.737 ksf x 3.33 spaces per ksf). With the proposed 7,982 square foot expansion, the clinic’s parking requirement would be 66 parking spaces, a net increase of 27 spaces over the current requirement.

Project Parking Supply
The clinic is proposing to add two spaces as part of its expansion, which would reduce its deficit to 17 spaces using the site-specific demand estimate, or to 25 spaces using the City Code requirement.
Availability of On-Street Parking Vacancy to Serve Project Demand
Based on our demand estimates and the survey data, it appears that some patients and most staff who drive currently use near-by on-street spaces. In the parking survey, which covered a roughly two-block radius from the project site, there were approximately 30 vacant, unrestricted spaces in which additional patients and staff could park, including 15 vacant spaces within 500 feet of the site. While these would potentially satisfy the extra demand from the expansion of the clinic, City of Berkeley staff have stated that, since the Project is located in a residential area, existing vacancies should not be relied upon to serve the Project’s parking requirement.
Mitigations for Parking Deficit
LifeLong Medical Care has committed to mitigate the full parking deficit based on the site-specific demand estimate, 17 spaces, with additional off-site parking. LifeLong is in the process of securing additional parking in up to three off-site lots. The agreements currently being negotiated include 15 spaces in the lot immediately west of 824 University, which is located about 550 feet from the Project site, and 2 or more spaces as required by the City, in the 824 University lot behind the Chaat Indian Restaurant or in the 1900 Fourth Street lot across from Spenger’s Restaurant, located 800 feet from the Project site. (This lot has as more than sufficient capacity to serve LifeLong’s entire deficit, if needed). In addition to these two sites, Lifelong is in discussions for the lease of additional spaces at 920 University (La Quinta Motel), located 600 feet from the project site. This lot has 22 surplus spaces.
In addition, the applicant is considering implementation of several strategies to reduce the overall vehicle trip generation and parking demand of the proposed project. One option is to provide commuter check transit subsidies to staff members to encourage using alternate modes to work. While the nearest Bay Area Rapid Transit (BART) station is over one mile away, there are many bus connections along University Avenue that travel through Downtown Oakland and Downtown Berkeley. To make the BART option more appealing, LifeLong Medical Care may investigate organizing one or more vanpools to either the North Berkeley, Downtown Berkeley, or Ashby BART stations, and/or participate in a joint venture with other West Berkeley employers to provide similar service. The West Berkeley Shuttle Service currently provides shuttle service between the
ATTACHMENT 6 ZAB 12-10-09 Page10of 36
Ms. Nance Rosencranz October 8, 2009 Page 11 of 11
Ashby BART station and West Berkeley south of Dwight Way, and the applicant is open to considering participation in this service if it extends closer to the Project site. Other options to reduce the number of single-occupancy vehicle trips by staff to and from the site are to encourage carpooling, provide increased bike parking and shower facilities on-site.
Implementation of carpooling/vanpooling incentives, transit subsidies, and bike parking/on-site shower facilities has the potential to reduce vehicle trip generation and corresponding parking demand by 5 to 10 percent or more, based on available research and case studies nationwide. (One summary report on employer-based programs is included in the technical appendix, in a separate volume.) The actual reduction that may be achieved at the Project site cannot be quantified based on these studies, as each employment site is unique. However, the implementation of such measures is becoming more and more common as traffic congestion and concerns about climate change increase, and we understand that Lifelong Medical Care is committed to investigating all feasible options to reduce vehicle trips and parking demand.
SUMMARY OF FINDINGS
The 7,982 foot expansion to the current West Berkeley Family Practice facility will increase peak hour trips to and from the clinic by over 50 percent, but will have little effect on the traffic operations at the intersection of University Avenue and Sixth Street, the closest major intersection. We conservatively assumed that all project trips would come into and leave the site through this intersection, and distributed them according to the existing proportions on each roadway segment. The additional trips do not have a significant impact on the operations at the intersection and no mitigation is needed.
Based on surveys conducted at the site and considering the operating characteristics of the site, it is estimated that the proposed project would have a peak parking demand of 19 additional vehicles. LifeLong Medical Care proposes to mitigate this deficit through a combination of two additional on-site spaces and up to 17 additional off-site spaces. In addition, LifeLong Medical Care will investigate and implement as feasible a number of trip reduction strategies, including carpool/vanpool incentives, transit incentives and/or subsidies, provision of bike lockers and shower facilities, and participation in an extended West Berkeley Shuttle service, if and when the service can be extended into the Project area.
