Elementary School on nearby Mercedes Lane (across Laurel Road from the site). At the conclusion of the hearing, the City Council directed Staff to oversee a supplemental traffic study that included analysis of potential pedestrian impacts. City Staff hired Fehr and Peers to conduct the study. It is noted that the cost for the study was covered equally by the two applicants of the development projects and the property owner per a pass-through account with the City, but the consultants were managed by City Staff from beginning to end.
Study Purpose and Key Elements
Purpose
Per the Introduction of the Laurel Plaza Supplemental Traffic Operations Analysis Assessment (hereafter “traffic analysis” or “study”) the study’s purpose is to “…evaluate the potential effects of the development of the Laurel Plaza Project on the nearby area roadway Levels of Service, evaluate the proposed site plan, review collision trends adjacent to the Project site, and assess the Project’s compatibility with the adjacent transportation network and land uses.” Due to the interest of impacts to the nearby school, Fehr and Peers waited at least a week after school was back in session from summer break to obtain more accurate traffic counts and observations, which were conducted in August 2021. The Study looked at the existing transportation system, including Laurel Road, O’Hara Avenue, and Mercedes Lane. It also factored Tri-Delta bus services, bicycle facilities, and pedestrian facilities.
Data Collection
Data collection in August 2021 was done during weekday mornings and afternoon peak periods to coincide with the time-periods when adjacent street traffic demands are the greatest, and with the nearby school’s departure patterns. That data collection also included Laurel Elementary School Field Observations of pick-up and drop-off activities, as summarized in the following bullet list:
Inadequate pick-up and drop-off capacity at Laurel Elementary School results in vehicles spilling back onto Laurel Road.
One of the eastbound through lanes on Laurel Road gets blocked, prohibiting through movement, due to pick-up and drop-off.
Vehicles in the westbound left turn lane at Laurel Road and Mercedes Lane are unable to complete their movement due to vehicle spill back from the drop-off and pick-up areas.
Parents use the Laurel Plaza parking lot to drop off their children or park their vehicle at Laurel Plaza and walk their children to and from school. In the afternoon peak hour, more than 100 pedestrians were observed to cross Laurel Road, primarily due to pick-up and drop-off occurring in Laurel Plaza. A crossing guard at Laurel Road and Mercedes Lane is present to assist children crossing to and from Laurel Plaza.

Site Plan Reviews
The study looked at both site plans and assessed internal circulation for vehicles, pedestrian, and bicycles. Recommendations were provided as summarized below:
Provide signage on-site that indicates parking is for Laurel Plaza customers only, and that school pick-ups and drop-offs are prohibited.
Eliminate spaces 35, 36, and 37 (McDonald’s) to increase the drive-through throat depth and accommodate additional vehicle queues. Shift the drive-through pedestrian crossing to the east, bulb out the pedestrian areas adjacent to the crossing, and incorporate a raised crossing to improve pedestrian visibility. Additionally, include a 10-to15-foot pedestrian barrier (i.e., fence) to the right of pedestrians existing McDonald’s building to increase visibility to vehicles exiting the drive-through.
Provide at least four bicycle parking spaces (McDonald’s). Shift the Quick Quack internal north-south connector to align with the McDonald’s driveway.
Laurel Road and Mercedes Lane
Suggestions for improvements to the Laurel Road/Mercedes Lane intersection provided in the study included:
Modifying the traffic signal phasing and timing to install leading pedestrian intervals at the intersection to improve pedestrian visibility and reduce potential conflicts between pedestrians and vehicles.
Install blank out “No Turn on Red” signage for the eastbound and southbound approaches. This signage should be operational during school pick-up and dropoff periods only. Install high-visibility crosswalks with advanced stop bars for all crosswalks.
Vehicle Miles Traveled (VMT)
Vehicle miles traveled per the requirements of SB 743 were analyzed in the study. Based on guidance by CCTA (Contra Costa Transportation Authority) and OPR (Governor’s Office of Planning and Research) the project can be assumed to have a less than significant impact.
Conclusions
Results of the study show that no new impacts were identified and operations of the intersections that would provide primary site access would not significantly change with the addition of the project traffic. The proposed projects would generate less traffic than the previously approved projects for the same locations within Laurel Plaza. Inadequate pick-up and drop-off capacity at the adjacent Laurel Elementary School results in a substantial number of parents using the Laurel Plaza shopping center parking lot to pick-up and drop-off 165
Subject: Laurel Plaza Supplemental Traffic Operations Analysis Assessment – Work Session Date: January 25, 2022
their children, which results in pedestrians crossing Laurel Road at Mercedes Lane during the morning and afternoon peaks with the school stationed crossing guard at the location.
Assessment of historic collisions in the vicinity of the project site were found to be substantially below predicted values on roadways of similar design and capacity. Based on the results of the study, the recommendations covered throughout this Staff Report would enhance site access, circulation, and safety for all travel modes.
Analysis
The Laurel Plaza Supplemental Traffic Operations Analysis Assessment was conducted based on City Council direction to look at potential pedestrian impacts associated with the two proposed development projects in Laurel Plaza. Staff also requested the consultants to analyze on site circulation, level of service at nearby intersections, opportunities for enhancements, and VMT. The study identified a very low incident count at the study intersections, and that Laurel Road pedestrian crossings during pick-up and drop-off were mostly attributable to the use of Laurel Plaza as a pick-up and drop-off location, likely due to overcrowding and traffic backups onto Mercedes Lane and Laurel Road. The owners and future developers of Laurel Plaza should not be responsible to solve the lack of pick-up and drop-off availability on school grounds; however, there are still several recommendations that can ensure future development of the commercial site functions in a safe manner with the proximity of the school, and those recommendations are included throughout this Staff Report and summarized in in the “Conclusions” section of the attached study.
When considering the findings of the traffic analysis, the development projects should be able to proceed with their requests for conditional use permits and designs reviews with the recommendations in the study integrated into their applications. It is noted these recommendations are not results of lowering significant impacts to a less than significant level, rather only recommendations for enhancements and improvements to the on- and offsite functions.
Recommendation
Staff recommends the City Council direct the applicants of both development projects to modify their projects to implement all the onsite recommendations, and direct Staff to work with the applicants on ways to proceed with implementing the off-site recommendations.

FinalMemorandum
Date: January 7, 2022
To: Kenneth Strelo, City of Oakley
From: Mark Howard, Cody Lim, and Bill Burton, Fehr & Peers Subject: Laurel Plaza Supplemental Traffic Operations Analysis Assessment WC21-3831
This technical memorandum documents the results of the updated transportation analysis prepared for the development of the Laurel/O’Hara Retail Center (Project) in Oakley, California. A previous study, Draft Traffic Impact Study for the Laurel/O’Hara Retail Center dated April 10, 2007, for development of this retail parcel was prepared by Kimley-Horn and approved by the city. An updated transportation study, Oakley McDonald’s and Quick Quack Traffic Analysis dated March 15, 2021, was completed by Kimley-Horn to analyze proposed modifications to the original land use plan reviewed and approved in 2007. This transportation assessment was prepared to review and update the analysis and recommendations of the previous traffic studies.
The current site features a 4,000 square foot bank and a gas station with convenience market. The proposed project would add a 4,597 square foot McDonalds restaurant and 3,600 square foot Quick Quack carwash. Future development of the site would include adding a shopping center with 26,000 square feet of retail space. The primary purpose of this evaluation is to identify the effects of the proposed project on the surrounding transportation system, with an emphasis on potential impacts and conflicts of McDonald’s and Quick Quack carwash related traffic with local school traffic (specifically, Laurel Elementary School).
ExecutiveSummary
The results of this transportation assessment indicate that the operations of the study intersections would remain within the acceptable level of service limits outlined by the City of Oakley’s deficiency thresholds when project traffic is added to existing traffic levels. Vehicle queues would slightly increase with the addition of the proposed project trips, but not to the degree to cause negative consequences to circulation. Field observations found that inadequate pick-up and drop-off City of Oakley

capacity exists at Laurel Elementary School, causing excessive vehicle queuing and parents pickingup or dropping-off their children in Laurel Plaza.
Based on the results of the assessment and field observations, the following improvements are recommended to enhance site access, safety, and circulation for all travel modes:
Install high-visibility crosswalks with advanced stop bars for all crosswalks at the intersection of Laurel Road & Mercedes Lane.
Modify the signal phasing to include leading pedestrian intervals at the Laurel Road/Mercedes Lane intersection to improve pedestrian visibility and reduce conflicts between pedestrians and vehicles.
Install blank out “No Turn on Red” signage to increase pedestrian safety for the eastbound and southbound approaches at the Laurel Road/Mercedes Lane intersection. The blank out signs should be operational during school pick-up and drop-off hours. Provide signage on-site in the Laurel Plaza center that indicates parking is for Laurel Plaza customers only (i.e., Laurel Elementary School parking, pick-up and drop-off is prohibited). Eliminate spaces 35, 36 and 37 in the McDonald’s parking lot due to potential conflicts with drive-thru queues. Increase the drive-thru throat depth to accommodate additional vehicle queues.
Shift the drive-thru pedestrian crossing to the east, bulb out the pedestrian areas adjacent to the crossing, and incorporate a raised crossing to improve pedestrian visibility.
Additionally, include a 10-to-15-foot pedestrian barrier (i.e., fence) to the right of pedestrians exiting the McDonalds building to increase visibility to vehicles exiting the drive-thru.
Provide bicycle parking as part of the proposed project. To provide for safe and more efficient on-site circulation, shift the Quick Quack internal connector south to align with the McDonalds driveway.
Introduction
This section discusses the study’s purpose, study locations, analysis scenarios, analysis methods, and criteria used to identify potential violations of the city’s established Level of Service policies.
Study Purpose and Project Description
The study’s purpose is to evaluate the potential effects of the development of the Laurel Plaza Project on the nearby area roadway Levels of Service, evaluate the proposed site plan, review 170

collision trends adjacent to the Project site and assess the Project’s compatibility with the adjacent transportation network and land uses. The Project site is in the City of Oakley, bound by Laurel Road to the south, O’Hara Avenue to the east, and residential development to the north and west. (See Figure 1 – all figures are provided at the end of this memorandum). The existing site is currently occupied by a gas station with a convenience store and a drive-in bank. Complete buildout of the development will include a shopping center with 26,000 square feet of retail space, a 4,597 square foot McDonalds, and a Quick Quack carwash. Vehicular access would be provided via Laurel Road and O’Hara Avenue. The project site plans are shown on Figure 2A and 2B.
Study Location and Analysis Scenarios
The effects of the Project on the study area roadway facilities were determined by measuring the change in delay that Project-generated traffic would create at intersections in the vicinity of the site during the weekday morning (7:00 to 9:00 AM) and afternoon (1:30 to 6:00 PM) peak periods. Based off project trip generation, trip distribution and previous traffic reports prepared for this plaza, analysis of the following intersections were included in the assessment:
1. Laurel Road/O’Hara Avenue
2. Laurel Road/Mercedes Lane
Operations of signalized intersections were evaluated using the method from Transportation Research Board’s Highway Capacity Manual 6th Edition methods. The following scenarios were evaluated:
1. Existing – Based on traffic counts collected at the above intersections when area schools were in normal session. The existing conditions analysis makes use of the highest hour of traffic counted during the observation period.
2. Existing Plus Project – Existing traffic counts plus traffic generated by the proposed Project.
3. Cumulative – Projected traffic volumes based on traffic growth trends that are described in the Oakley General Plan and supplemented by traffic forecasts for the study area in the 2040 Contra Costa Countywide travel demand model. Land uses assumed on the parcels adjacent to the Project site, including the parcels zoned for commercial and retail business at the Laurel Road & O’Hara Avenue intersection.
4. Cumulative with Project – Cumulative forecasts plus traffic expected to be generated by the Project.

Analysis Methods
The operations of roadway facilities are described with the term “level of service” (LOS). LOS is a qualitative description of traffic flow from a vehicle drivers’ perspective based on factors such as speed, travel time, delay, and freedom to maneuver. Six levels of service are defined ranging from LOS A (free-flow conditions) to LOS F (over-capacity conditions). LOS E corresponds to operations “at capacity.” When volumes exceed capacity, stop-and-go conditions result, and operations are designated LOS F.
Signalized Intersections
Traffic conditions at signalized intersections were evaluated using methods developed by the Transportation Research Board (TRB), as documented in the Highway Capacity Manual 6th Edition for vehicles using the analysis software Synchro 11.0. The HCM method calculates control delay at an intersection based on inputs such as traffic volumes, lane geometry, signal phasing and timing, pedestrian crossing times, and peak hour factors. Control delay is defined as the delay directly associated with the traffic control device (i.e., a stop sign or a traffic signal) and specifically includes initial deceleration delay, queue move-up time, stopped delay, and final acceleration delay. The relationship between LOS and control delay for signalized intersections is summarized in Table 1. 176

Table 1: Signalized Intersection LOS Criteria
Level of
Service Description Delay in Seconds
A
Progression is extremely favorable and most vehicles arrive during the green phase. Most vehicles do not stop at all. Short cycle lengths may also contribute to low delay.
< 10.0
B Progression is good, cycle lengths are short, or both. More vehicles stop than with LOS A, causing higher levels of average delay. > 10.0 to 20.0 C
Higher congestion may result from fair progression, longer cycle lengths, or both. Individual cycle failures may begin to appear at this level, though many still pass through the intersection without stopping.
> 20.0 to 35.0
D
The influence of congestion becomes more noticeable. Longer delays may result from some combination of unfavorable progression, long cycle lengths, or high V/C ratios. Many vehicles stop, and the proportion of vehicles not stopping declines. Individual cycle failures are noticeable. > 35.0 to 55.0
E
This level is considered by many agencies to be the limit of acceptable delay.
These high delay values generally indicate poor progression, long cycle lengths, and high V/C ratios. Individual cycle failures are frequent occurrences. > 55.0 to 80.0
F
This level is considered unacceptable with oversaturation, which is when arrival flow rates exceed the capacity of the intersection. This level may also occur at high V/C ratios below 1.0 with many individual cycle failures. Poor progression and long cycle lengths may also be contributing factors to such delay levels. > 80.0

Regulatory Setting and LOS Policies
Intersection levels of service were evaluated in this study for General Plan compliance and to identify potential transportation improvements that could be implemented as part of the Project to improve the overall operations of the transportation system for all travel modes. The City of Oakley generally strives to maintain level of service D operations for signalized intersections, unless other standards are adopted by CCTA or another regional agency.
The Project could have a noticeable effect on local and regional travel if it would cause an increase in traffic which is substantial in relation to the traffic load and capacity of the street system (i.e., result in a substantial increase in either the number of vehicle trips, or delay and congestion at intersections), or change the condition of an existing street (e.g., street closures, changing direction of travel) in a manner that would substantially change access or traffic load and capacity of the street system. Criteria were developed based on level of service policies contained within the City of Oakley General Plan and previously used by the City of Oakley as signalized intersection thresholds of significance.

Recommendations will be designed to enhance mobility for all travel modes, including transit vehicles, without degrading or precluding the provision of planned bicycle, pedestrian, and transit facilities. Intersection or roadway improvements may be recommended under the following circumstances for signalized intersections:
1. Project-related traffic causes the Level of Service (LOS) rating to deteriorate from LOS D (55-seconds) or better to LOS E or F, or from LOS E to LOS F.
2. For intersections already operating at an unacceptable LOS without the Project it is considered a significant impact of the Project increase the average intersection delay by more than 5 seconds.
ExistingConditions
This section describes the transportation facilities in the study area, including the surrounding roadway network, transit, pedestrian, and bicycle facilities in the Project’s vicinity. Existing intersection operations are also described.
Existing Transportation System
Vehicular access to the site is provided from Laurel Road, O’Hara Avenue, and Mercedes Lane.
Laurel Road is an east-west arterial road with two travel lanes in each direction, traveling from State Route 4 to Teton Road in the City of Oakley. The posted speed limit along Laurel Road is 35 miles per hour. Sidewalks are located on both sides of the roadway along the Project frontage.
Adjacent land uses along Laurel Road are primarily residential. Laurel Elementary School is bounded by Laurel Road to the north.
O’Hara Avenue is a north-south suburban roadway that provides two lanes in each direction, connecting Oakley to Brentwood. Land uses along O’Hara Avenue primarily consist of residential, developments, with vacant parcels that have a commercial or retail designation for future development. There is a posted speed limit of 35 miles per hour, and a designated sidewalk along the western side of the roadway along the Project frontage.
Mercedes Lane is a north-south local residential roadway that connects Laurel Plaza to the nearby residential area with one lane in each direction. Laurel Elementary School is located on the western side of the roadway. There is a sidewalk on the western side of the road adjacent to the Elementary School and posted speed limit of 25 miles per hour.
178

Transit Service
Transit service in the area is provided by Tri Delta Transit with transit stops located within 0.5 miles of the Project site. There are stops located north of the project site at O’ Hara Avenue & West Cypress Road which provide both eastbound and westbound travel for routes 383, 391, and 393.
Additional stops exist east of the project site along Laurel Road which provide east and westbound travel for Route 383. Route 383 connects the study area to the Antioch BART Station on weekdays with 60-minute headways from 5:00 AM to 6:00 PM. Route 391 connects the study area to the Brentwood Park & Ride and the Antioch & Pittsburg Center BART stations on weekdays. The route runs from 5:00 AM to 11:00 PM on 30-minute headways in the AM peak hours, 15-minute headways in the PM peak hours, and 60-minute headways during off-peak hours. Route 393 provides weekend service from the study area to the Antioch BART station on 60-minute headways from 8:00 AM to 12:00 AM on Saturdays and 60-minutes headways from 7:00 AM to 10:00 PM on Sundays and holidays.
Bicycle Facilities
Class II bike lanes denoted by pavement striping exist in both directions along Laurel Road. There are also Class II bike lanes along O’Hara Avenue in both directions, north of the O’Hara Avenue & Laurel Road intersection. However, only the bike lane on the western side of O’Hara Avenue continues south past the intersection.
Pedestrian Facilities
There are existing sidewalks along both sides of Laurel Road and the western side of O’Hara Avenue with crosswalks at all four approaches of the Laurel Road/O’Hara Avenue intersection and all the approaches except the westbound approach at the Laurel Road/Mercedes Lane intersection. The western crosswalk at Laurel Road/Mercedes Lane experiences higher than normal pedestrian volumes in the morning and afternoon peak times due to Laurel Plaza being used as a pickup/drop-off area for students attending Laurel Elementary School.
Data Collection
Intersection turning movement counts were collected in August 2021 during the weekday morning (6:00-9:00 AM) and afternoon (1:30-6:00 PM) peak periods to coincide with the time-periods when adjacent street traffic demands are the greatest, and with the nearby school arrival and departure patterns. The counts were collected at the intersection of Laurel Road and O’Hara Avenue, immediately adjacent to the Project site, and at the intersection of Laurel Road and Mercedes Lane, the location of one of the Project driveways. The traffic analysis incorporates volumes from the highest hours of traffic observed during the count periods, which reflect peak traffic associated with activities at the Laurel Elementary School. Peak hour intersection vehicle volumes are summarized 179

in Figure 3 along with existing lane configurations and traffic controls. Existing pedestrian and bicycle volumes are summarized in Figure 4. The traffic counts for existing conditions at O’Hara Avenue/Laurel Road and Mercedes Lane/Laurel Road are provided in Attachment A.
Laurel Elementary School Field Observations
Field observations of pick-up and drop-off activities at the Laurel Elementary School were conducted. The following observations were made:
Inadequate pick-up and drop-off capacity at Laurel Elementary School results in vehicles spilling back onto Laurel Road.
One of the eastbound through lanes on Laurel Road gets blocked due to pick-up and drop off.
Vehicles in the westbound left turn lane at Laurel Road & Mercedes Lane are unable to complete their movement due to vehicle spill back from the drop-off and pick-up area. Parents use Laurel Plaza to drop off their children or park their vehicle at Laurel Plaza and walk their children to and from school. In the afternoon peak hour, more than 100 pedestrians were observed to cross Laurel Road, primarily due to pick-up and drop-off occurring in Laurel Plaza.
A crossing guard at Laurel Road & Mercedes Lane is present to assist children crossing to and from Laurel Plaza.

Existing Intersection LOS
Existing intersection lane configurations, signal timings, and peak hour turning movement volumes were input into the Synchro 11.0 software program to calculate the levels of service for the study intersections during each peak hour. The existing conditions peak hour intersection LOS results are presented below in Table 2. Detailed LOS calculation worksheets can be found in Attachment B. Both intersections were found to operate within the level of service standards set by the City of Oakley during both peak hours. 181

ProjectCharacteristics
This section provides an overview of the proposed Project components and addresses the proposed Project trip generation, distribution, and assignment characteristics, allowing for an evaluation of potential Project effects on the surrounding roadway network. The amount of traffic associated with the Project was estimated using a three-step process:
1. Trip Generation – The amount of vehicle traffic entering/exiting the Project site was estimated.
2. Trip Distribution – The direction trips would use to approach and depart the site was projected.
3. Trip Assignment – Trips were then assigned to specific roadway segments and intersection turning movements.
Trip Generation
Trip generation refers to the process of estimating the amount of vehicular traffic a project would add to the surrounding roadway system. Estimates are created for the daily condition and for the peak one-hour periods during the morning and afternoon commute when traffic volumes on the adjacent streets are typically the highest. Project trip generation was estimated using rates from the data found in the Institute of Transportation Engineers (ITE) Trip Generation Manual (10th Edition). The ITE Trip Generation Manual is a published guide on trip generation rates of various land uses. It is continually updated and includes information on over 170 land uses. The Trip Generation Manual is considered the industry standard for transportation professionals for evaluating the potential transportation outcomes of various land use decisions within the United States.
Trip generation estimates were developed for the proposed Project and existing land uses.
Reduction in the form of pass-by and internal capture trips were applied to reflect a more accurate estimation of the site’s trip generation. Pass-by trips are a subset of trips traveling along a road that make a stop at a location along their route. These vehicles are already travelling along the street system with a different ultimate destination in mind. They are not considered as new trips, since they are just stops along a trip route that was already occurring. They are assigned to the project’s driveways, but not the adjacent street network. Internal capture trips are trips contained within an integrated mixed-use development. Since mixed-use developments contain multiple different land uses, people may travel between the various uses, making multiple stops within a single trip. The trip generation data from the ITE Trip Generation Manual reflects all trips generated by a specific land use and does not factor out pass-by and internal capture trips. Adjustments for reductions 186

associated with both trip types were made from data provided within the ITE Trip Generation Handbook (3rd Edition), a supplemental document to the ITE Trip Generation Manual. The results of this assessment are presented in Table 4. The proposed McDonalds, Quick Quack Car Wash and Shopping Center is anticipated to generate 2,154 daily trips, 146 AM peak hour trips and 177 PM peak hour trips on a typical weekday.

Project Trip Distribution and Assignment
Project trip distribution refers to the directions of approach and departure that vehicles would take to access and leave the site. Estimates of regional project trip distribution were developed based on existing travel patterns in the area, the City’s Vistro Model, and the location of complementary land uses. The resulting trip distribution percentages are shown on Figure 5. The Project trip generation estimates, in combination with the expected trip distribution patterns, were used to assign vehicle trips to the local roadway network, as shown on Figure 6. 188

This section presents the evaluation of intersection Levels of Service under Existing with Project conditions.
Existing with Project Traffic Volumes
The Project traffic volumes on Figure 6 were added to the existing traffic volumes from Figure 3 to estimate the Existing with Project traffic volumes, as shown on Figure 7.
Analysis of Existing with Project Conditions
Intersection Operations
Existing with Project intersection operations were evaluated using the methods described in Section
1. The Existing with Project analysis results are presented in Table 5, based on the traffic volumes and intersection configurations presented on Figure 7. Table 5 also includes the operations results for Existing conditions. The addition of project traffic would slightly increase delay at the study intersections, but not result in conditions that fall below the City of Oakley’s thresholds.

CumulativeTrafficConditions
This section discusses Cumulative traffic conditions both without and with the Project.
Cumulative Traffic Volumes
Cumulative forecasts were developed using traffic growth trends as described in the Oakley General Plan and supplemented by a check of traffic forecasts for the study area in the 2040 Contra Costa Countywide travel demand model. To develop a more accurate 2040 cumulative forecast, future potential developments on the surrounding parcels adjacent to the project site were included in this analysis scenario. The three relevant parcels are located to the northeast, southeast, and southwest relative to the Laurel Road & O’Hara Avenue intersection and are zoned for future retail development. The potential additional future trips associated with development on these parcels were manually added to the model forecasts. Table 7 shows the trip generation associated with the adjacent parcels.

The resulting Cumulative without Project forecasts and lane configurations are presented in Figure 8, which are representative of anticipated conditions in the year 2040. The project volumes from Figure 6 were added to the Cumulative without Project traffic volumes to represent Cumulative with Project Conditions, as presented on Figure 9.
Heavy vehicle percentages and pedestrian and bicycle activity at the study intersections were left unchanged with respect to existing conditions. Traffic signal timing was optimized at intersections where the initial analysis indicated LOS D, E or F operations, reflecting that as part of Oakley’s continuing maintenance of traffic signals, signal timing for intersections near capacity are regularly updated to better accommodate actual travel demand.

Analysis of Cumulative Conditions
Intersection Operations
Levels of service calculations were conducted to evaluate intersection operations under Cumulative conditions both without and with the Project. The LOS results are summarized in Table 8. The corresponding LOS calculation sheets are included in Attachment B. The results of the LOS calculations indicate that with planned development and growth in Oakley in the cumulative condition, the intersection of O’Hara Avenue at Laurel Road will operate at LOS E during the morning peak and will be below acceptable serviceable levels during the afternoon peak as dictated by the City of Oakley. The addition of project traffic is expected to further degrade the operation of O’Hara Avenue at Laurel Road, but the intersections will remain at their same service level classifications.

Vehicle Queues
The addition of Project traffic is expected to increase vehicle turn queues at Laurel Road & O’Hara Avenue, as illustrated in Table 9. Though queues would exceed available storage by more than 25 feet for several movements in the “Without Project” cumulative scenario, project traffic would further increase the lengths of these queues. Below are listed those movements for which project volumes would further exacerbate excessive queue lengths at Laurel Road & O’Hara Avenue in the cumulative condition:
Southbound left turn (storage capacity of 175 feet) increases from 175 to 200 feet in the morning peak hour and 250 to 300 feet in the afternoon peak hour. 198

Collision Data Review and Countermeasures
A quantitative crash/collision analysis was prepared using collision data from the Statewide Integrated Traffic Records System (SWITRS) collected over a five-year period (January 1, 2015 through December 31, 2019). The two study locations for this assessment include the segment of Laurel Road between Woodhill Drive and O’Hara Avenue and the intersection of Laurel Road and Mercedes Lane.
Over the five-year period, there were 10 total collisions with reported injuries or property damage.
There were 2 collisions within the study segment with 1 non-severe visible injury collision and 1 property damage only collision. There were 8 collisions at the Laurel Road/Mercedes Lane 199

intersection, and all were property damage only collisions. Of all collisions within the study area, 9 collisions were property damage only, and 1 collision was a non-severe visible injury. There were no fatal or severe injury collisions within the study area in the five-year evaluation period. Table 10 summaries the collision severity along the study segment and at the study intersection on Laurel Road.

Table 11 summarizes the collision types for the analysis segment and at the intersection. None of the collisions involved a bicyclist or pedestrian within the five-year evaluation period. Rear end collisions were the most common collision type with 5 rear-end collisions of the 10 total collisions.
All of collisions that occurred along the study segment were rear end collisions. The study intersection had 3 broadside collisions, 1 sideswipe collision, and 1 hit object collision. All but one collision in the study area involved multiple vehicles. The only single vehicle collision was a hit object collision that occurred at the intersection.

Table 12 summarizes the primary collision factors for the study segment and at the study intersection. Unsafe speed is the most common collision factor as the primary factor for 5 of the 10 total collisions. All collisions that occurred along the study segment were due to unsafe speed. The study intersection had 3 collisions due to unsafe speed, 2 collisions due to traffic signals and signs, 1 collision due to following too closely, and 1 collision due to unsafe starting or backing. A collision map is provided in Figure 10.

Predictive Method Comparison and Collision Concerns
A comparison of the observed collision frequencies to the expected collision frequencies was prepared. The predictive method analysis used for the crash rate comparison is based on the procedures outlined in the AASHTO Highway Safety Manual (HSM). The predictive method for urban and suburban arterials is a procedure used to estimate the expected average crash frequency within a study area. It accounts for traffic volume and various roadway characteristics such as the cross section, number of driveways, annual daily traffic, speed, presence of on-street parking, and fixed objects near the roadway. When observed crash data is available, the Empirical Bayes method is applied within the predicted method to combine predicted average crash frequency with observed crash frequency. The segment of Laurel Road from Woodhill Drive to O’Hara Avenue and the intersection of Laurel Road and Mercedes Lane were defined as the study area for the collision assessment. Since observed crash data is available, the area was evaluated using the Empirical Bayes Method within the predictive method.
The number of crashes expected is presented as the number of crashes per year. Using the model, the expected number of crashes per year is 1.8 along the study segment and 4.7 at the study intersection. Based on the SWITRS collision data, there were 2 crashes over five years (0.4 crashes per year) along the study segment and 8 crashes over five years (1.4 crashes per year) at the study intersection. Table 13 shows the actual and predicted collision frequencies of the study segment and intersection. The data indicates that fewer accidents occur within the study area than would be expected at locations with similar characteristics.

Fehr & Peers also evaluated the collision trends based on the type of occurrence. The collisions that occurred most frequently were rear end collisions and broadside collisions which occurred 6 and 3 times respectively. Although they are the most common, the number of occurrences is small, and below the predicted values. With rear end accidents averaging 1.2 occurrences per year and broadside collisions averaging less than one occurrence per year.
Site Plan Review
This section summarizes the assessment of site access and internal circulation for vehicles, pedestrians, and bicycles. See Figure 11A and 11B for a summary of the site plan recommendations.
McDonalds
Site access is proposed to be provided from two existing driveways on Laurel Road, one full access signalized intersection at Laurel Road & Mercedes Lane and one unsignalized right-in, right-out intersection east of Mercedes Lane. From field observations, as previously discussed, it was noted that extensive pick-up and drop-off activity occurs in Laurel Plaza for Laurel Elementary School associated with inadequate capacity at that location.
Site Recommendation 1: Provide signage on-site that indicates parking is for Laurel Plaza customers only and that school pick-ups and drop offs are prohibited.
Vehicles in the drive-thru queue may obstruct vehicle parking spaces 35, 36 and 37 during peak customer periods.
Site Recommendation 2: Eliminate spaces 35, 36 and 37. Increase the drive-thru throat depth to accommodate additional vehicle queues.
Pedestrian access is provided via the Laurel Road & Mercedes Lane intersection and by an access point located on Laurel Road between the two driveways. The pedestrian path connecting to Laurel Road between Mercedes Lane and the Project driveway has a path of travel that crosses the drivethru travel lanes. With the proposed layout, the building may impede pedestrian visibility for vehicles leaving the drive-thru.
Site Recommendation 3: Shift the drive-thru pedestrian crossing to the east, bulb out the pedestrian areas adjacent to the crossing, and incorporate a raised crossing to improve pedestrian visibility. Additionally, include a 10-to-15-foot pedestrian barrier (i.e., fence) to the right of pedestrians exiting the McDonalds building to increase visibility to vehicles exiting the drive-thru.

Bicycle lanes are provided on Laurel Road for bicyclists traveling to the Project site, however it is unclear if bicycle parking is included on site.
Site Recommendation 4: Provide at least four bicycle parking spaces.
Quick Quack Car Wash
Site access is proposed to be provided primarily from three existing driveways, two on Laurel Road, and one on O’Hara Avenue. Both driveways on Laurel Road are unsignalized right-in, right-out intersections; the driveway located on O’Hara Avenue is a full access unsignalized intersection.
Bicycle lanes are provided on Laurel Road for bicyclists traveling to the Project site with bicycle parking located on-site along the pedestrian path on the southern portion of the site. Pedestrian access is provided by an access point on Laurel Road. Pedestrian paths of travel are provided for pedestrians wishing to go to other parts of the shopping plaza. An on-site intersection is proposed in the northeast corner of the project site that does not align with the on-site driveway associated with the proposed McDonald’s. Offset intersections are nonstandard and may present safety and operational issues.
Site Recommendation 1: To provide for safe and more efficient on-site circulation, shift the Quick Quack internal north-south connector to align with the McDonalds driveway.
Laurel Road & Mercedes Lane Recommendations
Based on the intersection operations analysis, collision assessment and observations made during school pick-up and drop-off activities, the following improvements are suggested for pedestrian and vehicle activity at this Laurel Road/Mercedes Lane intersection:
Modify the traffic signal phasing and timing to install leading pedestrian intervals at the intersection to improve pedestrian visibility and reduce potential conflicts between pedestrians and vehicles.
Install blank out “No Turn on Red” signage for the eastbound and southbound approaches.
This signage should be operational during school pick up and drop off periods only. Install high-visibility crosswalks with advanced stop bars for all crosswalks. 205

Vehicle Parking Requirements
Parking requirements and design guidance are outlined in the City of Oakley Municipal Code of Ordinances Chapter 9.1.1402. For the proposed McDonald’s, the City’s Municipal code specifies a minimum of one (1) parking space per each 150 square feet of net public area for primary use eating and drinking establishments. For the Quick Quack Carwash, the City’s Municipal Code calls for one (1) space for each five hundred (500) square feet of gross floor area. Thus, seven total parking spaces are required for the Quick Quack Carwash. The current proposed site shows 71 parking spots provided within the adjacent parking lot which is more adequate for the required 38 minimum spots.
Vehicle Miles Traveled
On September 27, 2013, Senate Bill (SB) 743 was signed into law. The California state legislature found that with the adoption of the Sustainable Communities and Climate Protection Act of 2008 (SB 375), the State had signaled its commitment to encourage land use and transportation planning decisions and investments that reduce vehicle miles traveled and thereby contribute to the reduction of greenhouse gas emissions, as required by the California Global Warming Solutions Act of 2006 (Assembly Bill 32). In December 2018, the Governor’s Office of Planning and Research (OPR) finalized new CEQA guidelines (CEQA Guidelines section 15064.3), that identify vehicle-miles traveled (VMT) as the most appropriate criteria to evaluate a project’s transportation impacts.
The implementation of SB 743 eliminated the use of criteria such as auto delay, level of service, and similar measures of vehicle capacity of traffic congestion as the basis for determining significant impacts as part of CEQA compliance. The SB 743 VMT criteria promote the reduction of greenhouse gas emissions, the development of multimodal transportation networks, and a diversity of land uses.
In November 2017, OPR released a technical advisory containing recommendations regarding the assessment of VMT, proposed thresholds of significance, and potential mitigation measures for lead agencies to use while implementing the required changes contained in Senate Bill 743 (SB 743). Also in November 2017, OPR released the proposed text for Section 15064.3, “Determining the Significance of Transportation Impacts,” which summarized the criteria for analyzing transportation impacts for land use projects and transportation projects and directs lead agencies to “choose the most appropriate methodology to evaluate a project’s vehicle miles traveled, including whether to express the change in absolute terms, per capita, per household or in any other measure.” OPR recommends that for most instances a per service population threshold should be adopted and that a fifteen percent reduction below that of existing development would be a reasonable threshold.
209
Kenneth Strelo
January 7, 2022
As the City of Oakley has not yet formally adopted VMT criteria, standards, or thresholds at the time this report was prepared, this assessment follows the current OPR and CCTA guidance related to VMT.
Based on the guidance published by both CCTA and OPR, the project can be assumed to have a less than significant impact related to VMT. The project is a local serving retail use that is not expected to attract regional trips. Projects that consist of local-serving retail uses can be presumed to have a less-than-significant impact absent substantial evidence to the contrary, since these types of projects will primarily draw users and customers from a relatively small geographic area that will lead to short-distance trips and trips that are linked to other destinations.
Conclusions
Results of this transportation assessment indicate that no new impacts were identified and operations of the intersections that would provide primary site access would not significantly change with the addition of project traffic. Based on the land use changes on the proposed site, such as no pharmacy/drugstore, the currently proposed project would generate fewer trips than the project evaluated in the previously approved study. Inadequate pick-up and drop-off capacity at the adjacent Laurel Elementary School result in a substantial number of parents using the Laurel Plaza shopping center parking lot to pick up and drop off their children. This results in many pedestrians crossing Laurel Road at Mercedes Lane during the morning and afternoon peaks, with the school stationing a crossing-guard at this location. The assessment of historic collisions in the vicinity of the project site found collision rates substantially below predicted values on roadways of similar design and volume (i.e., the adjacent roadways have operated in a manner safer than what would be expected with the given conditions). Based on the results of the transportation assessment, the following improvements are recommended to enhance site access, circulation, and safety for all travel modes.
Install high-visibility crosswalks with advanced stop bars for all crosswalks at the intersection of Laurel Road & Mercedes Lane.
Modify the signal phasing to include leading pedestrian intervals at the Laurel Road/Mercedes Lane intersection to improve pedestrian visibility and reduce conflicts between pedestrians and vehicles.
Install blank out “No Turn on Red” signage to increase pedestrian safety for the eastbound and southbound approaches at the Laurel Road/Mercedes Lane intersection. The blank out signs should be operational during school pick-up and drop-off hours. 210
Kenneth Strelo
January 7, 2022
Provide signage on-site in the Laurel Plaza center that indicates parking is for Laurel Plaza customers only (i.e., Laurel Elementary School parking is prohibited). Eliminate spaces 35, 36 and 37 in the McDonald’s parking lot due to potential conflicts with drive-thru queues. Increase the drive-thru throat depth to accommodate additional vehicle queues.
Shift the drive-thru pedestrian crossing to the east, bulb out the pedestrian areas adjacent to the crossing, and incorporate a raised crossing to improve pedestrian visibility.
Additionally, include a 10-to-15-foot pedestrian barrier (i.e., fence) to the right of pedestrians exiting the McDonalds building to increase visibility to vehicles exiting the drive-thru.
Provide bicycle parking as part of the proposed project. To provide for safe and more efficient on-site circulation, shift the Quick Quack internal connector south to align with the McDonalds driveway.
This completes our draft assessment of the Laurel Plaza shopping center development project.

From: Ben Huie, P.E.
Kimley-Horn and Associates, Inc.
Date: March 15, 2021
Subject: Oakley McDonald’s and Quick Quack Traffic Analysis A McDonald’s fast food restaurant and a Quick Quack car wash facility are proposed to be developed on the northwest corner of Laurel Road and O’Hara Avenue in Oakley, CA. The 3,595 square-foot Quick Quack car wash facility will be located adjacent to the existing 7-11 gas station and convenience store, while the 4,597 square-foot McDonald’s will be located to the east of Laurel Road and Mercedes Lane. The proposed land uses will replace previously approved land uses within the parcel. KimleyHorn compared the trip generation between the previously approved land uses and the proposed land uses to determine if the project is estimated to generate more vehicle trips. A drive-through queuing and on-site circulation analysis was also conducted to evaluate the adequacy of the proposed drivethrough lanes for each project. In addition, on-site pedestrian circulation and access to nearby facilities will be evaluated to determine whether the McDonald’s project has adequate pedestrian access. The following discusses the methodology, analysis, and results of the trip generation comparison and queuing analysis.
BACKGROUND
A previous traffic study, Draft Traffic Impact Study for the Laurel/O’Hara Retail Center dated April 10, 2007, for this retail parcel was prepared by Kimley-Horn and approved by the City. The proposed McDonald’s restaurant will replace the 5,343 square-foot fast-food restaurant and 12-fueling position gas station that was planned in the traffic study. A trip generation study was conducted for the existing 7-11 gas station and convenience store, following the 2007 traffic impact study, in the Trip Generation Study for the Laurel Road and O’Hara Avenue Commercial Project dated January 9, 2017 which replaced the 17,270 square-foot pharmacy that was previously planned. The Quick Quack carwash will be an additional land use replacing the previously approved pharmacy/drugstore with drive-through window. The land use comparison is shown in Table 1. The proposed site plans are shown in Figure 1 and Figure 2 for the McDonalds and Quick Quack projects, respectively. The previous study site plan is shown in Figure 3.

TRIP GENERATION
PREVIOUS PROJECT
Trip generation is typically estimated by using the Institute of Transportation Engineers (ITE) Trip Generation Manual. The previous study used the then-current 7th Edition version of the Trip Generation Manual. The most current version is the 10th Edition version of the Trip Generation Manual. Therefore, the previous land uses were updated with the latest Trip Generation Manual, 10th Edition trip rates to accurately compare the two.
The same ITE Land Use Codes used to develop the trip generation in the 7th Edition for the previous project were also used to develop the trip generation in the 10th Edition for the proposed project, with the exception of the gas station, which was previously ITE Land Use Code 946 but has been updated to ITE Land Use Code 945 in the 10th Edition. Since the site contains retail uses, pass-by trip reductions were applied as specified in the ITE Trip Generation Handbook, 3 rd Edition to account for vehicle trips
that are already on the road and will choose to stop as they pass by the site. These are not new vehicle trips but considered to be pass-by trips. In addition, this parcel includes a multi-use development which has potential interaction among the uses within the site. These types of trips are considered internal to the site and are “captured” within the site. The standard engineering reference for determining internal capture reductions for the proposed project is the ITE Trip Generation Handbook, 3rd Edition. Using the 7 th Edition, the previously approved project was expected to generate a total of 8,110 daily trips, 223 AM peak hour trips, and 301 PM peak hour trips. It should be noted that the previous daily trip generation did not include internal capture and pass-by trips. Therefore, with the addition of internal capture and pass-by percentages, the daily trips results in a decrease from 8,110 daily trips to 3,668 daily trips. Using the 10th Edition, the previously approved project is expected to generate a total of 4,106 daily trips, 250 AM peak hour trips, and 308 PM peak hour trips. As a result of the change in methodology and trip generation rates from the 7th Edition to 10th Edition, the trips for the retail enter increases in daily, AM and PM peak hour trips.
The updated 10th Edition trip generation for the previous study is shown in Table 2. The trip generation comparison between the ITE Trip Generation Manual 7
th Edition and 10th Edition is shown in Table 3.
As shown, the 10th Edition results in slightly more peak hour trips than the 7th Edition. 253

Note: The previous 2007 traffic impact study, using the ITE Trip Generation Manual 7th Edition, assumes a daily trip of 8,110 trips without internal capture and pass-by reductions. With both internal capture and pass-by reductions, the daily trip results in 3,668 trips.
PROPOSED PROJECT
The number of project trips for the proposed project was also estimated using the Institute of Transportation Engineers (ITE) Trip Generation, 10th Edition. For the proposed developments, average rates were used to estimate the number of project trips based on ITE Land Use 934 (Fast-Food Restaurant with Drive-Through) for the McDonalds and ITE Land Use 948 (Automated Car Wash) for the Quick Quack. Pass-by reduction and internal capture were applied to the proposed retail site using 254
kimley-horn.com 4637 Chabot Dr., Suite 300, Pleasanton, CA 94588 925-398-4840 the same methodology as the previous land use assumptions. Table 4 presents the trip generation for the entire retail site with the proposed project. The proposed retail site is anticipated to generate 3,480 daily trips, 222 AM peak hour trips, and 286 PM peak hour trips. It should be noted that although the shopping center, gasoline station, and drive-in bank uses and sizes do not change from the previous to proposed land use assumptions, the internal capture trips show minor changes as a result of the changes in land use and size for the entire retail center.

TRIP COMPARISON
With the previous project and proposed project trip generations shown in Tables 2 and 4, Table 5 summarizes the comparison between the two versions of the project. The proposed project will result in 626 fewer daily trips, 28 fewer AM peak hour trips, and 22 fewer PM peak hour trips. Since the daily, AM, and PM peak hour trips decreased, the proposed project should not result in any additional impacts than identified in the previous traffic study.

QUEUING ANALYSIS
The following section provides the queuing analysis for each project. The queuing analysis was conducted to determine whether drive-through lanes for each project would provide adequate capacity to accommodate the queues from the proposed uses and whether the queues would block on-site circulation or extend into either the internal driveway aisle or off-site arterial roadways. For the McDonald’s site, there are two proposed drive-through lanes that merge into one lane for a total storage length of 245 feet, which can accommodate 12 vehicles assuming a vehicle length of 20 feet. For the Quick Quack site, there are two proposed drive-through lanes that are 120 feet each for a total of 240 feet, which can accommodate 12 vehicles total.
DRIVE-THROUGH SERVICE TIMES
Due to the effects of COVID-19 and its shelter-in-place restrictions, collecting service times at similar McDonald’s and Quick Quack drive-through locations was not feasible. Therefore, service times from the Proposed McDonald’s Side-by-Side Drive-Through Modifications dated January 16, 2018, a previous Kimley-Horn study for a McDonald’s located at 10000 Crow Canyon Road in the Town of Danville, was used. Service times at the pick-up window, or the time between one vehicle arrival at the pick-up window to the next vehicle arrival, was collected at this McDonald’s location. The average service time observed at the pick-up window during the weekend dinnertime period was approximately 33 seconds per vehicle. For the Quick Quack car wash, the client provided an average service time of 180 seconds per vehicle.
DRIVE-THROUGH DEMAND
To determine the peak hour demand for both projects, trip generation for each land use were determined for the Saturday peak hour of generator as a conservative analysis. Based on data provided by the McDonald’s client, approximately 70 percent of orders are taken from the drive-through, while the remaining 30 percent are from inside the store. Therefore, the peak hour demand for the project drive-through is estimated to be 70 percent of the peak hour trip generation for the entire project site.
The Saturday peak hour of generator trip generation is shown in Table 6. McDonald’s is expected to generate 90 inbound Saturday peak hour trips and Quick Quack is expected to generate 19 inbound Saturday peak hour trips. These values were used to evaluate the queuing analysis. 256

QUEUING ANALYSIS
A micro-simulation model within an Excel Spreadsheet was used to determine the drive-through queuing for the project. Based on the service times and the drive-through demands, a queuing analysis was run with 1,000 iterations for the Saturday peak hour of generator, assuming an average vehicle length of 20 feet. Of the 1,000 iterations completed for the McDonald’s drive-through, 95% of the iterations have a maximum queue of 13 vehicles or less. The McDonald’s drive-through lanes can accommodate approximately 12 vehicles; therefore, the proposed 95th percentile queue is expected to extend out of the McDonald’s drive-through lane by one vehicle. However, based on the site plan, the one vehicle exceeding the drive-through lane storage would have a minimal effect on adjacent parking spaces. Of the 1,000 iterations completed for the Quick Quack drive-through, 95% of the iterations have a maximum queue of 10 vehicles or less. The two Quick Quack drive-through lanes of 120 feet each lane can accommodate approximately 12 vehicles total; therefore, the proposed length of Quick Quack drive-through lanes is sufficient to accommodate the 95th percentile queue.
PEDESTRIAN ACCESS
The following provides a description of the pedestrian facilities on-site and off-site to determine the McDonald’s adequacy of pedestrian access to nearby land uses. Since the McDonald’s project, and not the Quick Quack car wash, is most likely to attract pedestrians from nearby uses, such as Laurel Elementary School located southwest of the intersection of Laurel Road and Mercedes Lane, pedestrian access to the McDonald’s site was evaluated. The following provides a description of the pedestrian connectivity to the project site:
Laurel Road and Mercedes Lane Intersection
o Yellow marked crosswalks are provided on the north, south, and west legs of the intersection to allow pedestrians on the south side of Laurel Road, such as students from Laurel Elementary School, to access the McDonald’s site. Each crosswalk has a pedestrian signal.
257
kimley-horn.com 4637 Chabot Dr., Suite 300, Pleasanton, CA 94588 925-398-4840 o America Disability Act (ADA) ramps are provided at each end of each crosswalk at the intersection.
o In discussion with the City, there is a crossing guard on the west leg of the intersection during school days to assist students and parents crossing Laurel Road. o An eastbound right turn (EBR) on red is restricted from 7:30 AM to 8:30 AM and from 1:00 PM to 3:00 PM during school days since students are crossing the south leg of the intersection.
The existing sidewalk on the north side of Laurel Road (east of the intersection of Laurel Road and Mercedes Lane), connects to the pedestrian pathway that provides access to the McDonald’s project site from the south. An ADA ramp is proposed at this pedestrian crossing. The existing sidewalk on the west side of Mercedes Lanes (north of the intersection of Laurel Road and Mercedes Lane), connects to a proposed ADA ramp and the proposed pedestrian pathway that leads to the McDonald’s project entrance from the north. Additional proposed ADA ramps are provided throughout the project site. The proposed McDonalds drive-through queue is not expected to extend beyond the entrance of the parking lot and conflict with the pedestrian pathway just north of the drive-through entrance.
Based on the City of Oakley Municipal Code, Title 9.1.1402 (l3)1, “The on-site pedestrian circulation system shall be lighted to enhance pedestrian safety and allow its use at night”. Therefore, increased visibility at the pedestrian pathway that crosses the McDonald’s drive-through lane is recommended to warn drive-through patrons of pedestrians crossing. It is recommended that sufficient lighting be provided and/or warning signs be provided to increase driver awareness. In addition, it is recommended that the landscaping within the pedestrian pathway, north of the drive-through entrance, allow for pedestrian visibility to oncoming vehicles traveling to and from the intersection of Laurel Road and Mercedes Lane. A summary of the on-site and off-site pedestrian facilities is provided in Attachment A.
CONCLUSION
Based on the results of the traffic analysis, the proposed project would not result in any new traffic impacts compared to the previously approved project. The proposed project would generate approximately 626 fewer trips daily, 28 fewer trips in the AM peak hour, and 22 fewer trips in the PM peak hour from the previously approved study. McDonald’s is expected to generate a 95th percentile queue of 13 vehicles, with one vehicle extending out of the storage capacity of 12 vehicles. However, this one vehicle is not expected to significantly affect the operations of the adjacent parking spaces nor block the pedestrian crosswalk. Quick Quack is expected to generate a 95th percentile of 10 vehicles, which would also be accommodated by the storage capacity of 12 vehicles. The queuing analysis shows that the proposed project drive-throughs would be sufficient and no changes to the site are recommended. Many existing and proposed pedestrian facilities are provided on-site and off-site to 1 Oakley Municipal Code, Title 9 Land Use Regulation, City of Oakley, November 2020. 258
kimley-horn.com 4637 Chabot Dr., Suite 300, Pleasanton, CA 94588 925-398-4840 assist with pedestrian access and connectivity to the McDonald’s project site. Existing pedestrian facilities include crosswalks, sidewalks, ADA ramps, and crossing guards for the Laurel Elementary School. Proposed pedestrian facilities include pedestrian pathways and ADA ramps that connect to the McDonald’s project entrance. It is recommended that increased visibility to the pedestrian walkway is provided to warn drive-through patrons of pedestrians potentially crossing as vehicles exit the drivethrough. Examples of improvements include providing luminaires or warning signs.
