TO: HONORABLE MAYOR AND CITY COUNCIL

GEORGE RODERICKS, CITY MANAGER
FROM: GABRIELA RUIZ, PUBLIC WORKS ASSOCIATE ENGINEER
VIA: ROBERT OVADIA, PUBLIC WORKS DIRECTOR
DATE: JUNE 17, 2026
SUBJECT: THE TOWN CENTER/LIBRARY AREA PARKING AND

DINKELSPIEL STATION LANE PEDESTRIAN PATHWAY

EVALUATIONS

RECOMMENDATION
Staff recommends the City Council review the results of the Parking Study for Town Center/Library Complex and Vicinity and the Dinkelspiel Station Lane Pedestrian Pathway evaluation; and provide relevant feedback and direction to staff regarding potential parking area and pedestrian walkway improvements.

BACKGROUND
The FY 2025/26 Capital Improvement Program (CIP) budget included an analysis of parking in and around the Town Center/Library complex as well as the Town Center & Library Circulation Project – Holbrook-Palmer Park Connection to review and analyze pedestrian connectivity option and traffic adjustments around Town Center to facilitate access and mobility between the Town Center and Holbrook-Palmer Park, along Dinkelspiel Station Lane. The City Council, at their meeting on January 21, 2026, approved a professional services agreement with TJKM Transportation Consultants to conduct the evaluations.

The existing parking lot at the Town Center and Library Complex currently has 98 parking spaces for vehicles and 3 spaces for motorcycles. The Complex experiences recurring parking challenges due to the success of the Town Center and Library. The parking demand exceeds the capacity of the existing parking lot and has impacted the residential streets around the Complex. To address these concerns, the Town has implemented a permit parking program for Ashfield Road and Maple Avenue and encourages visitors to park at Holbrook Palmer Park, where there is ample parking.

Currently, Dinkelspiel Station Lane does not have a dedicated walkway or sidewalk between Maple Avenue and Watkins Avenue to facilitate pedestrian mobility between the Town Center Complex and Holbrook-Palmer Park. Due to the limited right-of-way along Dinkelspiel Station

Town Center/Library Parking and
Dinkelspiel Station Lane Pedestrian Walkway
JUNE 17, 2026

Lane, consideration of one-way traffic along area streets may need to be evaluated to facilitate such improvement.

The study was authorized to evaluate parking needs, and improvements at the Town Center as well as to identify how pedestrian facilities can be implemented along Dinkelspiel Station Lane to enhance safety and mobility for pedestrian, bicycle and vehicular traffic.

ANALYSIS
Parking Study
The Parking Study evaluated the current parking supply and demand for the following:
• Town Center/Library Complex Parking Lot
• Street parking along Watkins Avenue, Walnut Avenue, Maple Avenue, Ashfield Road, and Fair Oaks Lane; all between El Camino Real and Dinkelspiel Station Lane • Street parking along Lloyden Drive between Fair Oaks Lane and Belleau Avenue The Town Center Parking Lot inventory is shown in Table 1:

In March 2026, a survey was conducted to assess the parking needs of the Town employees, Mademoiselle Collette café and Library staff. The net driving demand for employees across all departments is approximately 40 spaces on a typical weekday, as shown in Table 2. Parking demand associated with the Mademoiselle Collette café includes at least two employee vehicles during peak hours, delivery trucks twice a day, and a customer count ranging between 100 and 200 on weekdays (including overlap with Library demand). Parking demand for Library patronage is difficult to accurately access; however, door sensor counts shows Mondays and Thursdays as the most visited days with around 500 entries per day. In addition, the Library maintains a full 7-day schedule every week of various programs and events. The most recurring program is Storytime, which averages around 100 attendees.

Town Center/Library Parking and
Dinkelspiel Station Lane Pedestrian Walkway
JUNE 17, 2026

Parking Data was collected for Tuesday-Thursday, March 3-5, 2026, from 9am to 5pm. Manual counts were collected every hour for a total of 8 hours (Table 3). The key findings from the parking occupancy data:
• Regular spaces routinely hit critical capacity
• Peak demand is sharply concentrated in the 10am-1pm window • Afternoon recovery is consistent
• Demand is consistent across all three weekdays
• EV charging infrastructure meets the demand
• Handicap and accessible spaces remain largely available

Parking occupancy data was also collected on streets in the immediate vicinity of the Town Center for the following blocks:
• Watkins Avenue, Walnut Avenue, Maple Avenue, and Ashfield Road; all between El Camino Real and Dinkelspiel Station Lane (March 3-5, Tuesday-Thursday, 9am-5pm) • Fair Oaks Lane between El Camino Real and Dinkelspiel Station Lane (April 7-9, TuesdayThursday, 9am-5pm) • Lloyden Drive between Fair Oaks Lane and Belleau Avenue (April 7-9, TuesdayThursday, 9am-5pm)

Town Center/Library Parking and
Dinkelspiel Station Lane Pedestrian Walkway
JUNE 17, 2026

The key findings from the on-street parking assessment are as follows:
• Low overall utilization
• Peak demand occurs mid-morning
• Walnut Avenue has high demand
• Permit-restricted streets stay lightly used
• Limited to no spillover from Town Center Lot
Study found that the current parking enforcement policies and outcomes are appropriate and consistent with other communities with the characteristics and demographics similar to Atherton.

No changes are recommended at this time.

Potential Parking Lot Improvements:

Approximately 17 additional parking spaces can be added to the parking lot in the Town Center/Library complex by paving unimproved areas and restriping existing parking spots with narrower spaces. Additionally, a new pedestrian crossing is proposed to accommodate safer pedestrian crossing from the railroad track side to the Town Center/Library side. The preliminary estimate for design and construction is approximately $85,000.

Additionally, the Study recommends addressing the parking conditions in a multi-phase approach over the next several years. Phase I will include parking lot improvements and collect parking data six months after the additional of 17 spaces to determine if demand is better met. If not, Phase II may include consideration of rescheduling of Library programs to non-peak hours or relocation to the Holbrook Palmer Park. Additional alternatives could include consideration of incentives to employees for alternative parking, commuter benefit programs, flexible work schedule for employees and limited on-street parking permits for employees as well as additional analysis for the Library and café.

Dinkelspiel Station Lane Pedestrian Pathway
Holbrook-Palmer Park provides an opportunity for additional parking for the Town Center/Library Complex. The preliminary review indicates that Holbrook Palmer Park’s parking has ample spaces available during the weekdays. The Park is located off of Watkins Avenue, approximately 2,000 feet away or about 8-10 minutes walking distance from the Town Center. Two alternatives were considered for improvements along Dinkelspiel Station Lane between Maple and Watkins.

Alternative 1 – Walkway Along Dinkelspiel Station Lane
• Provide a five-foot wide pedestrian walkway for the entire length of Dinkelspiel Station Lane from Maple Avenue to Watkins Avenue
• Installation of new ADA-compliant curb ramps and truncated domes at street crossings

Town Center/Library Parking and
Dinkelspiel Station Lane Pedestrian Walkway
JUNE 17, 2026

• To accommodate these improvements, relocation of a fire hydrant and a utility box at the Maple Avenue intersection and removal approximately 12 trees would be required. No parking would be permitted along Dinkelspiel Station Lane. • The preliminary cost estimate for these improvements is approximately $205,000.

Alternative 2 – Retaining Parking Spaces and Partial Walkway Along Dinkelspiel Station Lane • Retain approximately six marked parking spaces between Maple Avenue and Walnut Avenue, and restrict parking between Walnut Avenue and Watkins Avenue. • Provide a five-foot wide walkway between Walnut Avenue and Watkins Avenue with new ADA-compliant curb ramps and truncated domes
• To accommodate these improvements, relocation of a fire hydrant and a utility box at the Maple Avenue intersection and removal approximately 10 trees would be required. • The preliminary cost estimate for these improvements is approximately $145,000.

Each of the two alternatives result in different outcomes. Alternative I maximizes benefits to pedestrians and bicyclists providing safer and convenient walking and cycling environment along the two blocks of Station Lane. It results in loss of six parking spaces. Alternative II maintains parking between Maple and Walnut and adds a walkway between Walnut and Watkins. It does not improve the current walking environment between Maple and Walnut. For maximum benefit to all pedestrians and bicyclists, and to encourage more parking at the HPP Lot, Alternative I is preferred. The difference in the loss of trees and rough order of magnitude (ROM) costs for the two alternatives is not significant enough to choose one over the other.

The study also evaluated the intersection of Station Lane and Watkins Avenue, specifically related to pedestrian crossings. A key concern identified during the review is the potential for restricted visibility between southbound motorists on Watkins and pedestrians using the proposed crosswalk.

While field observations suggest that sight-distance limitations may exist, a detailed more detailed engineering evaluation is necessary to confirm the extent of the issue. This next phase of analysis would also include a more detailed assessment for the placement and visibility of pedestrian warning signs and other traffic control devices that could be accommodated. It is important to note that due to the proximity of the pedestrian crossing to the Watkins Avenue rail crossing, consultation with the California Public Utilities Commission will be needed and such consultation may limit warning devices that would detract from those associated with the rail crossing. At this time, the following improvements are recommended at this intersection:
• Installation of a new crosswalk and ADA-compliant curb ramps along Watkins, south of railroad tracks
• Removal of three (3) trees
• Installation of crosswalks related signs and traffic control devices to alert drivers along Watkins
• The estimated cost for these baseline improvements is included in the two alternatives discussed above

Town Center/Library Parking and
Dinkelspiel Station Lane Pedestrian Walkway
JUNE 17, 2026

Ultimately, the Study recommends the implementation of Alternative, providing a complete pedestrian walkway along Dinkelspiel Station Lane with the proposed crosswalk improvements at Watkins Avenue. This approach will not only benefit all pedestrians and bicyclists along Station Lane, but it will also encourage use of the Holbrook Park Parking Lot relieving the parking crunch at the Town Center.

The broader study included an evaluation of One-way traffic operations for Dinkelspiel Station Lane between Watkins and the Town Center, was contingent upon the completion of the Parking Study and a finding that a pedestrian walkway could only be added if the Town considered reducing the roadway width to accommodate the walkway. Since the Parking Study identified street improvements that can create a five-foot wide walkway along Station Lane, One-way operation analysis was not conducted.

With Council feedback and direction, staff can solicit a proposal for full design services for the outlined improvements.

FISCAL IMPACT
Sufficient funds are available in the FY 2025-26 Capital Improvements Program Budget. Funds for Town Center & Library Circulation Project – Holbrook-Palmer Park Connection is included in the Civic Center Master Plan Implementation Program budget in the amount of $200,000.

GOAL ALIGNMENT
This Report and its contents are in alignment with the following Council Policy Goals:
• Goal B - Improve Public Safety & Emergency Preparedness • Goal E - Maintain and Improve Public Infrastructure

EXECUTIVE SUMMARY
The Atherton Town Center Complex that includes the City Hall and Atherton Library provides extensive services and programs to the Atherton community. In recent years, the Complex has seen increased activities that results in shortage of parking at the on-site parking lot. To fully assess the parking conditions and develop recommendations, in January 2026, the Town retained services of TJKM Transportation Consultants. The Scope of the Parking Study included assessment of the parking supply/demand imbalance at the parking lot and streets surrounding the Town Center, and development of recommendations to address the parking crunch . The Study also included an evaluation of the walking environment along Watkins Avenue and Dinkelspiel Station Lane between the Holbrook Palmer Park parking lot (HPP Lot) and the Town Center, with an intent to encourage parking at the HPP Lot and walking to the Town Center. In addition, TJKM completed a warrants analysis for the Middlefield Road intersections at Watkins Avenue and Fair Oaks / Palmer Lane, and final study report has been submitted to the Town. Figure 1 shows a Study Area Vicinity Map depicting all three study areas.

Parking Study
Currently, the Parking Lot has 98 parking spaces for vehicles and three spaces for motorcycles.

The Lot experiences very high demand during mid-day peak times, Monday through Thursday.

While the Lot may reach full capacity at times, any intrusion of vehicles into the neighborhood streets is minimal. Overall, the study resulted in the following key findings and recommendations:

2 ▪ Phase I – Specific improvements within the Lot, discussed in this report, will create additional 17 parking spaces. Considering the current level of parking shortfall, an addition of 17 spaces should be able to meet the parking demand for all employees and visitors in the near term. Estimated cost of these improvements is $82,200. ▪ Phase II – If parking demand continues to exceed the supply after addition of 17 spaces, other solutions and strategies should be evaluated for implementation.

Due to the possibility of negative impacts on some users, a phased approach is highly recommended.

Figure 1 – Study Area Vicinity Map

3 Dinkelspiel Station Lane Improvements
Station Lane between the Town Center and Watkins Avenue is approximately 20 feet wide with one travel lane in each direction and unimproved shoulders. Parking is allowed on the south side (residential side) only. The assessment of walking environment along the street resulted in two improvement alternatives. Alternative I includes a 5-feet wide walking path along Station Lane connecting Watkins Avenue to the Town Center, and no curb parking allowed in this section.

Alternative II includes creation of six marked parking spaces between Maple and Walnut (no walking path), and a 5-feet wide walking path between Walnut and Watkins (no parking). Both Alternatives include pedestrian safety and crosswalk improvements at the Watkins/Station Lane intersection. The study recommends Alternative I for implementation. Estimated cost of Alternative I improvements is $202,800.

Overall, this report recommends two improvements:

1. Town Center Parking Lot Improvements adding 17 spaces. Estimated cost is $82,200.

2. Dinkelspiel Station Lane Walking Path Improvements. Estimated cost is $202,800.

Additional details are provided below.

A. PARKING STUDY
TJKM completed a comprehensive assessment of the current parking supply and demand for the following:
▪ Town Center Parking Lot
▪ Watkins Avenue, Walnut Avenue, Maple Avenue, Ashfield Road, and Fair Oaks Lane; all between El Camino Real and Dinkelspiel Station Lane
▪ Lloyden Drive between Fair Oaks Lane and Belleau Avenue Details of the assessment, key findings and recommendations are further discussed below.

Town Center Parking Lot
The study completed an inventory of the current parking supply at the Town Center and Library Lot and existing parking demand for the City employees, visitors, and deliveries.

Parking Supply
The Lot currently has a total of 98 spaces for vehicles and three spaces for motorcycles. Table 1 shows all parking spaces by type of allowed use.

This inventory includes all spaces in various parking areas wrapped around the City Hall. Except one curbside pick-up space, all parking spaces are typical, perpendicular or at 90 degrees and at least nine feet wide allowing convenient parking for all users. Figure 2 shows existing parking layout.

Town Employee Parking Needs
In March 2026, a survey was conducted to assess the parking needs of the Town employees currently working at the Town Center. This brief survey was completed by Department representatives, and included questions relevant to part-time and full-time employee counts, their commute hours and mode, and other parking-relevant needs. All six departments completed the survey. A summary is provided in Table 2.

Here are the key findings from the Town Employee Parking Demand survey:
▪ Police dominates headcount but not parking - With 31 full-time employees, Police is by far the largest department, yet only 10 vehicles are parked on-site during daytime hours (7am–7pm). The remaining 21 employees either work nights (5 vehicles parked overnight) or are off-site, or do not drive to work, meaning the department's true parking footprint is much smaller than its staff size suggests.
▪ Net driving demand is 40 spaces on a typical weekday - Of total 68 employees (63 FT + 5 PT), 35 full-timers and 5 part-timers drive regularly, yielding a core daily demand of approximately 40 vehicles. This is a useful baseline for the Lot usage by the employees. ▪ Library creates the most parking variability - Staff count ranges between 6 to 14 depending on the day, and the vehicle count from 5 to 12. Some employees park on nearby streets (Station Lane, Lloyden, Holbrook Palmer Park) in the afternoon, creating a direct link between the Library scheduling and off-site parking usage. ▪ Planning is entirely part-time - The Planning department has no full-time staff and 5 part-timers working on-site at least 2 days per week. This means Planning's parking contribution is intermittent and harder to predict, but also has a lower impact on peak weekday demand.
▪ On-site presence is well below total headcount across all departments - Across the board, the number of employees working on-site and driving regularly is significantly lower than total staff (36 of 63 full-timers on-site; 35 actually driving). Nearly 45%

5 employees not generating daily parking demand suggests the Lot's employee load is manageable even as the town grows, provided scheduling remains distributed.

Table 2 – Town Employee Parking Needs
Mademoiselle Colette Coffee Shop Parking Needs
In addition to the Town Departments, Mademoiselle Colette Coffee Shop also provided information on their parking needs. Here are key takeaways:
▪ Employees - There are five on-site employees. The opener arrives at 7am and leaves between 1:30pm and 3:00pm. The closer arrives between 9am and 11am and leaves at 5pm. At least two employee vehicles are parked during the mid-day peak parking demand hours.

6 ▪ Customers - The customer count ranges between 100 and 200 on weekdays, most arriving between 8am and 1pm. Depending on how many customers arrive during the mid-day peak parking demand times, how many actually drive, and how long they stay, their impact on overall parking crunch could be significant.
▪ Deliveries and Pick-ups - The Distribution Truck arrives as early as 6:00am and leaves by 9:30am, well before the peak parking demand hours. The delivery truck arrives twice a day; only once during the peak demand times. Doordash pickups are less than 10 per days and spread throughout the day, resulting in no material impact on the parking crunch.

The information gathered so far suggests that the Coffee Shop visitors do contribute to the peak parking demand, the extent of which can be determined by a brief, well-structured survey of the Coffee Shop visitors. This survey should be conducted if the recommended near-term improvements (discussed below) do not fully address the current parking imbalance.

Library Programs and Services Parking Needs
The Library is open from 10am to 8pm, Monday-Thursday and from 10am to 5pm on FridaySunday. It offers popular programs and services that attract users throughout the day. From the review of the door sensor counts for eight weeks of January and February 2026, it appears that Mondays and Thursdays are the most visited days with around 500 entries per day and Fridays are the least visited days with entries around 325 per day. While it is difficult to accurately translate number of entries to number of parking spaces required, this data helps understand peak days and times when the Library attracts most visitors.

In addition to completing the employee survey and door counts, the Library shared monthly events calendars for four months (Dec. 2025 – Mar. 2026) with detailed information on events scheduled for each day. Here are the key findings across all four months of the Library programming:
▪ Storytime and Makerspace are the backbone of the schedule - Storytime (in its various forms: Signs & Rhymes, Baby Bounce, Family Storytime, Musical Jamboree) runs nearly every day of the week across all four months, making it the single most recurring program.

Open Makerspace & Sewing on Tuesdays and Thursdays evenings (5:30-7:30p) is equally consistent, appearing without exception every week across all months. Baby Bounce and Storytime are popular programs attracting around 50 and 100 attendees, respectively. ▪ Late afternoon (4-5p) is the prime children's programming slot - The overwhelming majority of kids' craft and activity events, cloud dough, felt keychains, paper crafts, Mario workshops, slime, DIY toys, are scheduled between 4p and 5p on weekdays, strongly suggesting this is the post-school pickup window the Library targets for family engagement.
▪ Mornings are adult-oriented, evenings are community-oriented - Tai Chi (11am-12pm Wednesdays), Yoga at Jennings (11:30am-12:30pm Thursdays), Walking Club (Fridays at 9:45am at Holbrook Palmer Park), and Book Club/Brain Games all cluster in the morning.

English Conversation Club (5-6p Mondays) and 3D Printing for Families (5:30-6:30p

7 Mondays) anchor the evening adult/family slots, creating a clear morning-adult/eveningcommunity rhythm. ▪ Mondays are the most programmatically dense day - Across all four months, Mondays consistently carry the highest number of simultaneous programs: Baby Bounce, Creative Writing, a children's craft activity, English Convo Club, and 3D Printing for Families - often five or more distinct events. This likely drives the highest visitor traffic of any weekday. ▪ Special/featured events rotate monthly and reflect cultural moments - Each month introduces 2-4 themed signature events tied to the season or cultural calendar: Lunar New Year activities and West Coast Lion Dance (February), Holi Splatter Art and Ramadan/Eid Storytime (March), holiday floral demos and tree lighting (December), and winter craft series (January). These events likely draw many first-time visitors beyond the regular audience.
▪ Library promotes learning and community engagement year around – Except for the major holidays, the Library maintained a full 7-day schedule every week, reflecting strong year-round programming commitment to the Atherton community.

Parking Enforcement
Since parking enforcement policies have measurable impact on the parking supply/demand imbalance, the study took a cursory look at the Town’s parking enforcement efforts. Based on the information provided by the Code Enforcement Team, here are some key findings:
▪ Parking enforcement is a shared responsibility. On a typical weekday, 3 to 5 police officers and one code enforcement officer are available to conduct parking enforcement activities and respond to parking-related concerns throughout the Town. ▪ Parking enforcement is active and ongoing. Permit parking restrictions on Maple Avenue and Ashfield Lane are enforced daily through both proactive patrols and complaint-based responses. Failure to obey permit parking signage is the most common violation in the Maple Avenue and Ashfield Lane permit parking areas. ▪ Enforcement has resulted in substantial compliance efforts. Since permit parking was implemented last fall, approximately 50 citations and a similar number of verbal warnings have been issued, demonstrating active education and enforcement of the new parking regulations.

The current parking enforcement policies and outcomes are appropriate and consistent with other communities with the characteristics and demographics similar to Atherton. No changes are recommended at this time.

Parking Data Collection
To assess the current parking demand at the Town Center Lot, TJKM, through a data collection vendor, collected parking occupancy data for Tuesday-Thursday, March 3-5, 2026, from 9am to

8 5pm. Manual counts were collected every hour for a total of 8 hours. Table 2 shows hourly parking occupancy for three days of data collection.

** - Hour beginning at 9 AM (i.e., count taken between 9 AM to 10 AM) Red = demand exceeding 90% of supply
Here are the key findings from the parking occupancy data:
▪ Regular spaces routinely hit critical capacity - The 84 regular spaces reached or exceeded the 90% threshold (76+ spaces) on all three observation days at 11am with Thursday recording a full 84/84 occupancy around 10am. This is a meaningful constraint

9 given that other space types (HC, motorcycle, EV) are reserved and not available to general parkers.
▪ Peak demand is sharply concentrated in the 10am-1pm window - All three days show regular space counts climbing steeply from 9am, peaking between 10-11am, then gradually declining through the afternoon. By 3pm, occupancy drops to the low-60s, well below critical levels.
▪ Afternoon recovery is consistent - Occupancy levels start tapering off after 2pm, implying that the elevated demand is primarily during the mid-day hours of 10am-2pm. ▪ Demand is consistent across all three weekdays - Tuesday, Wednesday, and Thursday show nearly identical patterns, suggesting this is a reliable baseline rather than an anomaly. The lot regularly operates near capacity during mid-day peak hours regardless of the day.
▪ EV charging infrastructure meets the demand - All four EV spaces were occupied only four times while at least three spaces were occupied six times during 24 observations over the three days. This level of usage indicates that the current EV charging demand is well supported by the existing infrastructure.
▪ Handicap and accessible spaces remain largely available - HC and HC Van Accessible spaces rarely recorded more than 1-2 occupied spaces at any hour, indicating ADA supply is adequate relative to current demand.

Overall, the current parking demand suggests that additional parking supply or reduced parking demand during the mid-day peak hours is necessary to relieve recurring parking congestion during those hours.

On-Street Parking
The study area described below and shown in Figure 1 contains approximately 173 on-street parking spaces. While curb spaces are not marked, the approximate inventory was arrived at by determining available curb space along these streets that can practically and safely accommodate vehicle parking. Appropriate adjustments were made for any driveways, narrow shoulders, and other physical obstructions.

To assess any impact of the parking crunch at the Town Center Lot and spillover parking into the neighborhoods, parking occupancy data was collected on streets in the immediate vicinity of the Town Center for the following blocks:
▪ Watkins Avenue, Walnut Avenue, Maple Avenue, and Ashfield Road; all between El Camino Real and Dinkelspiel Station Lane (March 3-5, Tuesday-Thursday, 9am-5pm) ▪ Fair Oaks Lane between El Camino Real and Dinkelspiel Station Lane (April 7-9, TuesdayThursday, 9am-5pm) ▪ Lloyden Drive between Fair Oaks Lane and Belleau Avenue (April 7-9, Tuesday-Thursday, 9am-5pm)
Hourly parking occupancy counts are provided in Table 4. Here are the key findings from the onstreet parking assessment:

10 1. Low overall utilization - The study area's 173 on-street spaces never exceeded 35% occupancy across all observed days and hours, indicating ample available capacity at all times.

2. Peak demand occurs mid-morning - The highest single recorded count was 60 occupied spaces (35%) at 11am on Tuesday, March 3. Although the demand is low throughout the day, it generally peaks between 10am-12pm and tapers off by 4pm.

3. Walnut Avenue has high demand - Walnut Avenue consistently showed the highest individual occupancy, frequently reaching 8-11 cars on each side, making it the most utilized street in the study area.

4. Permit-restricted streets stay lightly used - Ashfield Road and Maple Avenue, both subject to "Permit Parking Only, Monday-Friday 9am-6pm," rarely exceeded 5 occupied spaces per side, suggesting low permit demand or strong compliance discouraging nonpermit users.

5. No spillover from Town Center Lot - During the Town Center Parking Lot's highestdemand window (10am-12pm), neighborhood on-street occupancy ranged only 25-35%, with no measurable surge, indicating that the Lot's busy periods are not pushing overflow vehicles onto surrounding streets.

Overall parking assessment for the Town Center Lot and on-street parking indicate that the Lot consistently experiences peak demand during mid-day hours, specifically around 10am to 12pm.

It is likely that some employees or visitors arriving during peak hours are unable to find any open space at the Lot and choose to park at the HPP Lot on a nearby residential street. Although, the on-street parking occupancy data suggests that any such spillover into the residential streets is minimal. This finding further establishes that the Town Center Lot, even when full, could be short in supply by less than 10 vehicles. This imbalance in parking supply and demand can be primarily addressed in two ways – by increasing parking supply, or reducing parking demand. These options are further discussed below.

Increasing Parking Supply
For the highest convenience to the Town employees and visitors, increasing parking supply at the Town Center Lot is the most direct approach to meeting their parking needs at all hours. To identify potential opportunities for creating additional spaces, TJKM reviewed existing parking layout, conducted field observations and measurements, and discussed with Public Works staff on-site. A few design iterations resulted in identifying several opportunities to create a total of 17 additional spaces as outlined below:

For the Northern Section of the Lot (close to the tracks), 11 spaces can be added in the section that is currently closed-off for a construction project; two spaces can be added by reducing stall widths in a couple of sections and one space can be added where a tree was removed. Figure 3 shows the existing layout and a conceptual design outlining all improvements necessary to create a total of 14 additional spaces. In addition, a new pedestrian crossing will be added to accommodate safer pedestrian crossing within the Lot, from the railroad track side to the Town Center and Library side.

11 For the Southern Section, three new spaces can be added by converting currently unimproved areas into properly paved and marked parking area – two near the southern Fair Oaks driveway and one near the Ashfield Road end to the parking lot. Figure 4 shows the existing layout and a conceptual design outlining all improvements necessary to create a total of three additional spaces.

Total costs of design and construction, including contingencies for the entire lot is estimated at $82,200. Detailed cost breakdown is provided in Table 5. For 17 new spaces, this translates to $4,835 per space – relatively low investment that significantly benefits the Town Center employees and visitors.

Reducing Parking Demand
In addition to creating more supply, a typical parking assessment also explores strategies and solutions that result in reduced parking demand. Most urbanized areas across US and around the world aim at reducing parking demand for numerous reasons that include fiscal constraints to build and operate parking facilities, land use efficiencies, induced demand, negative environmental impacts of promoting auto travel over sustainable transportation options and equity. There is a wide variety of proven Transportation Demand Management (TDM) solutions that includes parking cash-out programs, paid parking, carpool/vanpool incentives, transit pass subsidies, pre-tax commuter benefit programs, incentives for walking or bicycling to worksites and much more. While benefits of such TDM programs are unquestionable, it is somewhat premature to consider them for the Town of Atherton at this time for the following reasons:
▪ The current parking crunch is mostly limited to mid-day hours, and the shortfall is likely under 10 spaces. There are realistic options to increase parking supply at a nominal cost.

In addition, dispersing parking demand from mid-day should also be considered. ▪ TDM solutions are typically geared towards reducing employee parking demand as they occupy parking spaces for nearly nine hours a day. Since mid-day crunch is a result of visitor parking who occupy over half of the total parking supply, any benefit of the TDM solutions will be limited.
▪ Most TDM strategies require commuter behavioral changes, and their benefits are realized over time. In addition, initial rollout, and on-going management of TDM programs require additional resources.

Parking Study Recommendations
Based on the study findings, it is recommended that the Town address the parking conditions in a multi-phase approach over the next several years.

Phase I – Improvements at the Town Center Lot

1. Implement Town Center Parking Lot improvements resulting in additional 17 parking spaces. Estimated cost is $82,200.

2. Collect parking occupancy data six months after the addition of 17 spaces to see if the parking demand is fully met at all hours. If not, consider Phase II implementation.

12 Phase II – Policy and Program Changes
Since adding parking supply at the Town Center Lot is not an option any longer, additional strategies and solutions should be explored that either reduce or disperse the parking demand.

This may include:
▪ Rescheduling of some programs and activities at the Library to non-peak hours or relocation to the Holbrook Palmer Park
▪ Incentives to Town employees who park at the Holbrook Palmer Park ▪ Incentives to employees for use of alternate commute options in-lieu of driving ▪ Pre-tax commuter benefit programs
▪ Flexible work schedule for employees
▪ Limited on-street parking permits for employees
These are some of the solutions that have worked well in many communities. Phase II should examine feasibility, costs, and benefits of such solutions for Atherton. The exploration will include further discussions with the two largest venues that attract over 50 percent of the visitors during the peak parking demand times of 10am to 12pm – Library and Coffee Shop. User surveys specific to these visitors will provide much-needed information on how many visitors drive and park solely to visit the Library or Coffee Shop and what are the days and times of their peak demand. Surveys to gauge employee interest in alternative commute options and level of incentives may also lead to most beneficial TDM solutions that could reduce employee parking demand and relieve parking congestion.

B. DINKELSPIEL STATION LANE IMPROVEMENTS
To increase the parking availability for the Town Center employees and visitors, Holbrook Palmer Park’s parking lot was evaluated where plenty of spaces are available during the weekdays. The Park is located off of Watkins Avenue, approximately 2,000 feet away or about 8-10 minutes walking distance to the Town Center. The entire walking environment, from the Park to the Town Center was evaluated resulting in the following findings:
▪ From the HPP Lot to the intersection of Watkins and Station Lane, the existing sidewalk on the east side (Park side), although narrow, offers convenient walking path with raised curb separating pedestrians from the travel lane. On the west side, unimproved shoulder of varying width exists, although not recommended for walking. ▪ The railroad crossing, just north of the Station Lane intersection is well marked for pedestrian crossing with ADA complaint truncated domes. ▪ Watkins Avenue at Station Lane, just south of the railroad crossing, does not have any marked crosswalks. A pedestrian needing to cross Watkins and continue walking along Station Lane toward Town Center would need a safer crossing. ▪ Station Lane between Maple Avenue and Watkins Avenue is approximately 20 feet wide with unpaved shoulders. Vehicles are routinely parked on the south side (residential side) while parking is not allowed on the north side (railroad tracks side). There are several wellgrown trees that limit available shoulder width to accommodate vehicles and pedestrians. ▪ Minimal streetlights exists along the entire path, from the Park to the Town Center.

13 The assessment identified several potential improvements that would improve overall walking experience between the Park and the Town Center resulting in relieving some of the parking congestion at the Town Center Lot.

There are two alternatives for Station Lane improvements between Maple and Watkins. Each of these improvements and Rough Order of Magnitude (ROM) costs are discussed below. It is noted that these improvements and ROM costs are for initial discussion purposes only. Additional surveying and review by a certified arborist are necessary to further validate these improvements.

Alternative I - Walking Path Along Station Lane
To encourage parking at the HPP Parking Lot and walking to the Town Center, it is critical to create a safe and comfortable walking experience along Station Lane between Maple and Watkins.

Currently, the south side of Station Lane has several mature trees constricting the available shoulder width at places. Although not a preferred option, with the removal of some trees, it is feasible to create a five-feet wide walking path for the entire section. Figure 5 shows a conceptual design that depicts the recommended improvements that include the following:
▪ Five-feet wide pedestrian path for the entire length
▪ Installation of new ADA-compliant curb ramps and truncated domes at several locations ▪ Relocation of a fire hydrant and a utility box at Maple intersection ▪ Removal up to 12 trees (subject to City Arborist review and approval) The ROM design and construction costs for these suggested improvements is approximately $202,800 (Table 6). This alternative creates safer walking environment required to encourage parking at the Holbrook Park Parking Lot. It also benefits nearby residents who walk and bike along Station Lane. The overall benefit to relieving parking crunch and improving walking and bicycling environment for all users provides a compelling reason to consider removal of several trees.

Alternative II - Parking Spaces & Walking Path Along Station Lane During very high parking demand at the Town Center, it is not unusual to see up to 5-8 vehicles parked along Station Lane between Maple Avenue and Watkins Avenue. Some of these vehicles are parked too close to the driveways or encroach into the travel lanes raising safety concerns.

This situation can be corrected by creating marked spaces where adequate shoulder width is available and restricting parking where unsafe. Leaving adequate clearances for the driveways and mature trees, six spaces can be created between Maple and Walnut. Due to over-grown trees and vegetation and very limited shoulder width, no formal spaces can be created between Walnut and Watkins. For this section, five-feet wide pedestrian walking path is recommended (similar to Alternative I). Figure 5 shows a conceptual design showing the following improvements:
▪ Six marked parking spaces between Maple and Walnut. No parking allowed between Maple and Watkins
▪ Five-feet wide walking path between Walnut and Watkins ▪ New ADA-compliant curb ramps and truncated domes
▪ Removal of up to 10 trees (subject to City Arborist review and approval)

14 The ROM costs for these improvements is approximately $143,800. Details are provided in Table

7. Comparison of Alternatives I and II – Each of the two alternatives result in different outcomes.

Alternative I maximizes benefits to pedestrians and bicyclists providing safer and convenient walking and cycling environment along the two blocks of Station Lane. It results in loss of six parking spaces. Alternative II maintains parking between Maple and Walnut and adds a walking path between Walnut and Watkins. It does not improve the current walking environment between Maple and Walnut. For maximum benefit to all pedestrians and bicyclists, and to encourage more parking at the HPP Lot, Alternative 1 is preferred. The difference in the loss of trees and ROM costs for the two alternatives is not significant enough to choose one over the other.

Dinkelspiel Station Lane / Watkins Avenue Crosswalk
The study evaluated the intersection of Station Lane and Watkins Avenue, specifically related to pedestrian crossings. The railroad tracks run parallel to Station Lane just north of its intersection with Watkins. This, along with a slight grade difference along Watkins, and not having a marked crosswalk creates somewhat challenging conditions for pedestrians wanting to cross Watkins at Station Lane, just south of the railroad tracks.

TJKM reviewed the feasibility and preliminary safety considerations associated with installing a new uncontrolled pedestrian crossing on Watkins at the south leg of the intersection. The proposed crossing location is immediately south of an active Caltrain crossing, where the railroad tracks create a vertical crest along the Watkins Avenue corridor.

A key concern identified during the review is the potential for restricted visibility between southbound motorists on Watkins and pedestrians using the proposed crosswalk. Due to the roadway profile, drivers approaching from the north may experience limited sight distance as they traverse the rail crossing crest, potentially reducing their ability to detect pedestrians at the proposed crossing location south of the tracks.

While field observations suggest that sight-distance limitations may exist, a detailed engineering evaluation is necessary to confirm the extent of the issue. This evaluation would include a topographic survey to accurately document roadway elevations at the proposed crosswalk, the railroad crossing crest, and the southbound vehicle approach. The survey data will allow for a formal sight-distance analysis that considers the relative elevations of drivers and pedestrians and determines whether adequate stopping and pedestrian visibility can be achieved.

Additional review should also assess the placement and visibility of pedestrian warning signs and other traffic control devices. Particular attention should be given to their interaction with existing railroad warning equipment, including flashing signals, to ensure that railroad infrastructure does not obstruct or diminish the effectiveness of pedestrian crossing warnings.

Irrespective of the implementation of the Station Lane Improvement alternatives discussed above, the following improvements are recommended at this intersection:
▪ Installation of a new crosswalk and ADA-compliant curb ramps along Watkins, south of railroad tracks

15 ▪ Removal of three trees
▪ Installation of crosswalks related signs and traffic control devices to alert drivers along Watkins
The recommended improvements will comply with the City Design Guidelines, Caltrans standards, and ADA regulations. The ROM cost for these improvements is included in the two alternatives discussed above.

Dinkelspiel Station Lane Recommendations
Alternative I and Watkins/Station Lane crosswalk improvements will not only benefit all pedestrians and bicyclists along Station Lane, but it will also encourage use of the Holbrook Park Parking Lot relieving the parking crunch at the Town Center. The study recommends implementation of these improvements. The estimated cost is $202,800.

CITY COUNCIL STAFF REPORT – REGULAR AGENDA
TO: HONORABLE MAYOR AND CITY COUNCIL

GEORGE RODERICKS, CITY MANAGER
FROM: GABRIELA RUIZ, ASSOCIATE ENGINEER
VIA: ROBERT OVADIA, PUBLIC WORKS DIRECTOR
DATE: JUNE 17, 2026
SUBJECT: MIDDLEFIELD ROAD TRAFFIC STUDY (WATKINS AVENUE

AND FAIR OAKS LANE)

RECOMMENDATION
Staff recommends that the City Council review the results of the Middlefield Road Traffic Signal/High Intensity Activated Crosswalk (HAWK) Beacon/Rectangular Rapid Flashing Beacon (RRFB) Warrant Study at Watkins Avenue and Fair Oaks Lane/Palmer Lane, provide feedback and direction to staff regarding next steps.

BACKGROUND
The FY 2025/26 Capital Improvement Program (CIP) budget included the evaluation of traffic control devices at both the Middlefield Road/Watkins Avenue and Middlefield Road/Fair Oaks Lane intersections. The City Council approved a professional services agreement with TJKM Transportation Consultants to conduct the evaluation at the City Council Meeting on January 21, 2026.

Middlefield Road at Watkins Avenue and Fair Oaks Lane intersections are currently stop controlled on the side street approaches to Middlefield Road. High traffic demand at both intersections lead to vehicular and pedestrian mobility concerns and long queues on the approaches to Middlefield Road, as left-turning vehicles at both intersections, and through movements at Fair Oaks Lane/Palmer Lane, struggle to find adequate gaps, particularly during peak hours.

To address these issues, signal warrant analysis and evaluation of Rectangular Rapid Flashing Beacon (RRFB) and High Intensity Activated Crosswalk (HAWK) at the Middlefield Road intersections with Watkins Avenue and Fair Oaks Lane was completed to determine appropriate improvements to improve mobility and safety at the intersections.

Middlefield Road Traffic Study
(Watkins Avenue and Fair Oaks Lane)
JUNE 17, 2026

The preliminary results of the warrant study were presented to the Transportation, Bicycle and Pedestrian Safety Committee at their meeting on May 26, 2026.

ANALYSIS
TJKM collected pedestrian, bicycle, and traffic counts, and vehicular speeds, evaluated the intersections of Middlefield Road at Watkins Avenue and at Fair Oaks Lane, and conducted a warrant analysis for traffic signals, rectangular rapid flashing beacons (RRFB) and pedestrian hybrid beacons (HAWK) at each location to enhance pedestrian safety and improve mobility of all modes (vehicle, bicycle and pedestrian).

The following summarizes the peak hour volumes and counts along Middlefield Road at Watkins Avenue and at Fair Oaks Lane:

At Watkins Avenue:

Vehicular:

Middlefield Eastbound – 8,939 (Daily); 748 (AM Peak); 662 (PM Peak) Middlefield Westbound – 9,334 (Daily); 542 (AM Peak); 802 (PM Peak) Middlefield Total – 18,273 (Daily); 1,290 (AM Peak); 1,464 (PM Peak) Watkins Avenue – 2,056 (Daily); 161 (AM Peak); 174 (PM Peak) Pedestrian: 3 (AM Peak); 3 (PM Peak)
At Fair Oaks Lane:

Vehicular:

Middlefield Eastbound – 5,632 (Daily); 601 (AM Peak); 415 (PM Peak) Middlefield Westbound – 7,158 (Daily); 441 (AM Peak); 635 (PM Peak) Middlefield Total – 12,790 (Daily); 1,042 (AM Peak); 1,050 (PM Peak) Fair Oaks Lane – 2,239 (Daily); 173 (AM Peak); 261 (PM Peak) Palmer Avenue – 437 (Daily); 121 (AM Peak); 18 (PM Peak) Pedestrian: 12 (AM Peak); 5 (PM Peak)
Warrant analyses are conducted in conformance with the California Manual of Uniform Traffic Devices (MUTCD) to evaluate whether thresholds are met for the installation of control devices such as traffic signals, HAWK signals, and rectangular rapid flashing beacons (RRFB) based on vehicular and pedestrian volumes, traffic accident history and other related factors.

A brief summary of Traffic Signal Warrants are as follows:

Warrant 1 – 8-hour vehicle volume – any one of the following would satisfy this warrant:

A. The Minimum Vehicular Volume, Condition A, is intended for application at locations where a large volume of intersecting traffic is the principal reason to consider installing a traffic control signal. This is compared hourly and 8 hours must be satisfied. (one-lane each

Middlefield Road Traffic Study
(Watkins Avenue and Fair Oaks Lane)
JUNE 17, 2026

way [urban] main roadway/approach roadway = 500 / 150). This is compared at both 100% and at 80% of the threshold.

B. The Interruption of Continuous Traffic, Condition B, is intended for application at locations where Condition A is not satisfied and where the traffic volume on a major street is so heavy that traffic on a minor intersecting street suffers excessive delay or conflict in entering or crossing the major street. This is compared hourly and 8 hours must be satisfied. (one-lane each way [urban] main roadway/approach roadway = 750 / 75). This is compared at both 100% and at 80% of the threshold.

C. The combination of Conditions A and B is intended for application at locations where Condition A is not satisfied and Condition B is not satisfied and should be applied only after an adequate trial of other alternatives that could cause less delay and inconvenience to traffic has failed to solve the traffic problems.

Warrant 2 – 4-hour vehicle volume – The Four-Hour Vehicular Volume signal warrant conditions are intended to be applied where the volume of intersecting traffic is the principal reason to consider installing a traffic control signal. Hourly vehicle volumes are plotted against a curve measuring the hourly vehicular volume of the major street (total of both approaches) and the corresponding vehicles per hour on the more critical minor-street approach (one direction only) and 4 hours need to plot above the curve.

Warrant 3 – Peak Hour – The Peak Hour signal warrant is intended for use at a location where traffic conditions are such that for a minimum of 1 hour of an average day, the minor-street traffic suffers undue delay when entering or crossing the major street.

Warrant 4 – Pedestrian Volume – is intended for application where the traffic volume on a major street is so heavy that pedestrians experience excessive delay in crossing the major street.

Warrant 5 – School Crossing - is intended for application where the fact that schoolchildren cross the major street is the principal reason to consider installing a traffic control signal.

Warrant 6 – Coordinated Signal System - Progressive movement in a coordinated signal system sometimes necessitates installing traffic control signals at intersections where they would not otherwise be needed in order to maintain proper platooning of vehicles.

Warrant 7 – Crash Experience - The Crash Experience signal warrant conditions are intended for application where the severity and frequency of crashes are the principal reasons to consider installing a traffic control signal.

Warrant 8 – Roadway Network - Installing a traffic control signal at some intersections might be justified to encourage concentration and organization of traffic flow on a roadway network.

Warrant 9 – Intersection near Grade Crossing - The Intersection Near a Grade Crossing signal warrant is intended for use at a location where none of the conditions described in the other eight traffic signal warrants are met, but the proximity of a grade crossing on an approach controlled by a STOP or YIELD sign at a highway-highway intersection is the principal reason to consider

Middlefield Road Traffic Study
(Watkins Avenue and Fair Oaks Lane)
JUNE 17, 2026

installing a traffic control signal. This warrant was not evaluated as the intersections are not near a rail crossing.

Table 1 summarizes the evaluation for the Middlefield Road and Watkins Avenue intersection, summarizes the Traffic Signal Warrants for the intersection and indicates that Warrants 1, 2, and 3 are satisfied based on vehicular volumes, and that warrants related to pedestrian volumes and accident history are not met:

Similarly, as shown in Table 2, Traffic Signal Warrants 1, 2, and 3 are satisfied for the Middlefield Road and Fair Oaks Lane/Palmer Lane intersection.

Middlefield Road Traffic Study
(Watkins Avenue and Fair Oaks Lane)
JUNE 17, 2026

Due to low pedestrian crossing volumes, the criteria for both the High Intensity Activated Crosswalk (HAWK) and the Rectangular Rapid-Flashing Beacon (RRFB) are not met at either location. The study recommends installation of new traffic signals at Middlefield Road and Watkins Avenue as well as at Middlefield Road and Fair Oaks Lane/Palmer Lane.

The next steps in the evaluation would include a signal timing analysis as a pre-cursor to design to understand how the signal would be operated to improve mobility and safety at the intersection and along the corridor.

The Committee recommended moving forward with the next step in the evaluation process and suggested that the evaluation include current as well as out-year volume projections and that the analysis show current operations, the impacts of installing the Watkins Signal, followed by the signal at Fair Oaks Lane/Palmer Avenue.

Staff is seeking feedback on the analysis and recommendation from the Committee as well as direction regarding next steps.

FISCAL IMPACT
Sufficient funds are available in the Capital Improvements Program Budget. Funds for Evaluation of traffic control devices and other improvements at both Middlefield Road/Fair Oaks Lane and Middlefield/Watkins Avenue is included in the Traffic Safety Improvement Program budget in the amount of $100,000.

GOAL ALIGNMENT

Subject: Signal Warrant Analysis and Evaluation of Rectangular Rapid Flashing Beacon (RRFB) and High Intensity Activated Crosswalk (HAWK) for Two Study Intersections along Middlefield Road in the Town of Atherton, California.

EXECUTIVE SUMMARY
In January 2026, Town of Atherton retained TJKM Transportation Consultants to conduct three studies.

Study A focuses on the Parking Study for the Town Center Complex and Vicinity, and Holbrook Palmer Park Parking Lot; Study B is for the Traffic Study for Middlefield Road; and Study C is for the Dinkelspiel Station Lane One-Way Operations. This technical memorandum presents analysis and results for Study B that involved warrants analysis for a new traffic signal, RRFB and HAWK at two study intersections – Middlefield Road and Watkins Avenue and Middlefield Road and Fair Oaks Lane/Palmer Lane.

For the Middlefield Road and Watkins Avenue intersection, Traffic Signal Warrants 1, 2, and 3 are satisfied because the eight-hour vehicular volume meets the required threshold for Condition B and attains 80 percent of the thresholds for Conditions A and B. Additionally, the four-hour vehicular volume and the peak-hour volume meet their respective criteria, including criterion B. Warrants 4 through 8 are not satisfied since pedestrian volumes fall short of the required levels, an insufficient number of schoolchildren were observed not meeting the school crossing warrant, the nearby signalized intersection lies less than 1,000 feet away, preventing compliance with the coordinated signal system warrant, only one crash occurred within a 12-month period, and the roadway network lacks enough major routes to fulfill the network warrant. Furthermore, because pedestrian crossing volumes are low, neither the High Intensity Activated Crosswalk (HAWK) nor the Rectangular RapidFlashing Beacon (RRFB) criteria are met at the intersection. Table 1 below provides the summary of the traffic signal warrant analysis for Middlefield Road and Watkins Avenue. 1

For the Middlefield Road and Fair Oaks Lane/Palmer Lane intersection, the Traffic Signal Warrants 1, 2, and 3 are satisfied since vehicular volumes meet the eight-hour, four-hour, and peak-hour criteria, respectively. Warrants 4 through 8, however, are not met because pedestrian volumes are below the required threshold, too few schoolchildren were recorded to justify the school crossing warrant, the nearby signalized intersection is located within 1,000 feet, thus not meeting the coordinated signal system warrant, crash data do not satisfy the crash experience requirement, and the roadway network lacks a sufficient number of major routes to meet the network warrant. Moreover, due to low pedestrian crossing volumes, the criteria for both the High Intensity Activated Crosswalk (HAWK) and the Rectangular Rapid-Flashing Beacon (RRFB) are not met at this location. Table 2 below provides the summary of the warrant analysis for Middlefield Road and Fair Oaks Lane/Palmer Lane.

INTRODUCTION
This technical memorandum presents result of a comprehensive evaluation of traffic signal warrants (Warrants 1 through 8) at two study intersections along Middlefield Road as requested by the Town of Atherton, in accordance with the criteria outlined in the California Manual on Uniform Traffic Control Devices (California MUTCD), 2026 Edition. The analysis incorporates peak hour turning movement counts, 8-hour vehicular volumes, and pedestrian crossing volumes to determine warrant satisfaction.

In addition, this memorandum discusses results of the evaluation for the applicability of alternative pedestrian crossing treatments, including a Rectangular Rapid Flashing Beacon (RRFB) and a HighIntensity Activated Crosswalk (HAWK) signal, based on pedestrian demand, roadway geometry, vehicular speeds, and safety considerations.

STUDY AREA
The Study included two intersections shown in the Vicinity Map below.

Middlefield Road and Watkins Avenue is a stop-controlled intersection with Watkins Avenue operating under stop control. Middlefield Road functions as a primary east-west arterial through the Town of Atherton, carrying relatively higher traffic volumes and serving regional connectivity. The intersection experiences peak hour turning movements associated with residential access, with limited pedestrian crossing opportunities across Middlefield Road due to higher vehicle speeds and traffic continuity. The peak-hour volume entering the intersection was recorded at 1,639 vehicles per hour (veh/h). The posted speed limit on Middlefield Road is 30 miles per hour (mph), while the posted speed limit on Watkins Avenue is 25 mph in the vicinity of the intersection.

Middlefield Road and Fair Oaks Lane/Palmer Lane is a closely spaced, offset unsignalized intersection, with Fair Oaks Lane and Palmer Lane forming a split intersection along Middlefield Road.

Both minor approaches operate under stop control, while Middlefield Road remains free-flowing. This configuration introduces potential operational and safety challenges, including conflicts, limited sight distance, and difficulty for pedestrians crossing the arterial. The intersection serves local residential traffic and generates intermittent peak hour turning movements, particularly during commuter periods. The peak-hour volume entering the intersection was recorded at 1,336 veh/h. The posted speed limit on Middlefield Road is 30 mph, while the posted speed limits on Fair Oaks Lane and Palmer Lane are 25 mph in the vicinity of the intersection.

DATA COLLECTION
TJKM collected 24-hour Average Daily Traffic (ADT) counts and 7-hour turning movement counts (TMC). 24-hour ADT was collected right next to the intersection leg for all the legs at the two study intersections to conduct the warrant analysis. ADT was collected on Tuesday, March 10, 2026, when the schools were in session. Below are the locations of ADT counts –

1. Middlefield Road, east of Watkins Avenue

2. Middlefield Road, west of Watkins Avenue

3. Watkins Avenue, south of Middlefield Road

4. Middlefield Road, east of Fair Oaks Lane/Palmer Lane

5. Middlefield Road, west of Fair Oaks Lane/Palmer Lane

6. Fair Oaks Lane, south of Middlefield Road

7. Palmer Lane, north of Middlefield Road

Vicinity Map
Turning Movement Counts (TMC) were collected for vehicles with peds and bikes for seven hours, three hours for the AM peak period and four hours for the PM peak period. TMC were collected on the same day of ADT on Tuesday, March 10, 2026, for the AM peak period between 07:00 AM to 10:00 AM and the PM peak period between 02:00 PM to 06:00 PM. Raw collision data was provided by the Town for both the study intersections. Appendix A contains recoded average daily traffic, turning movement counts and the provided collision data.

ANALYSIS AND RESULTS
The study included warrant analysis for a Traffic Signal, HAWK and RRFB, further discussed in Section I, II and III, respectively. The following appendices are also included – 4

• Appendix A: Data Collection (Average Daily Traffic Counts, Turning Movement Counts, and Raw Collision Data) [13]
• Appendix B: California MUTCD 2026 Edition Guidelines for Warrant Analysis [53] • Appendix C: Warrant 1, Eight-Hour Vehicular Volume Detailed Evaluation [98] • Appendix D: Detailed Traffic Signal Warrants Worksheet [101] I – Traffic Signal Warrant Analysis
There are total eight applicable signal warrants that apply at the two study intersections. The warrant analysis was conducted based on the guidelines established in the California MUTCD, 2026 Edition.

Middlefield Road and Watkins Avenue
Warrant 1 – Eight-Hour Vehicular Volume
Warrant 1 evaluates whether traffic volumes on the major street and the critical minor streets are sufficiently high to justify signalization over an extended period of the day. This warrant considers both individual and combined approach volumes and compares them against thresholds established in the California MUTCD, 2026 Edition. The intent is to identify locations where recurring traffic demand results in operational inefficiencies or delays that may be mitigated through signal control.

Both Condition A (Minimum Vehicular Volume) and Condition B (Interruption of Continuous Traffic) were evaluated for Warrant 1. Based on a comparison of the major-street and critical minor-street volumes to the 100 percent threshold criteria, four hours under Condition A and more than eight hours under Condition B exceeded the applicable thresholds. Accordingly, the MUTCD requirement of a minimum of eight qualifying hours is satisfied under Condition B. In addition, when comparing the combined approach volumes to 80 percent of the threshold criteria, both Condition A and Condition B recorded more than eight hours exceeding the reduced thresholds. Hence, warrant 1 is satisfied.

Detailed evaluation for Eight Hour Warrant 1 is contained in Appendix C.

Warrant 2 – Four-Hour Vehicular Volume
Warrant 2 evaluates whether traffic volumes during any four hours of an average day are sufficient to justify signalization. In accordance with the California MUTCD, 2026 Edition, this warrant is assessed by comparing the total volume on both approaches of the major street with the higher-volume approach on the minor street. These volumes are plotted against the criteria presented in Figure 4C1, and the warrant is considered satisfied when the plotted points fall above the applicable curve.

As required, four individual hours of traffic volumes were selected and analyzed. The evaluated hours include one hour from 8:00 AM to 9:00 AM, two hours from 2:00 PM to 4:00 PM, and one hour from 5:00 PM to 6:00 PM. For each of these hours, the total volume on the major street (both approaches) was plotted against the higher-volume minor street approach on Figure 4C-1 of the California MUTCD.

All plotted data points fall above the applicable curve. Hence, warrant 2 is satisfied. The plotted chart for Four Hour Warrant 2 is provided in Appendix D.

Warrant 3 – Peak Hour Volume
Warrant 3 evaluates traffic conditions during the single highest hour of an average day to determine whether a traffic signal is justified. In accordance with the California MUTCD, 2026 Edition, this warrant is intended to address locations where minor-street traffic experiences excessive delay when 5

attempting to enter or cross a major street during peak traffic conditions. The analysis is conducted using the criteria and curves presented in Figure 4C-3.

The California MUTCD specifies that satisfying any one of the applicable criteria is sufficient to meet the warrant. For this analysis, Criterion B was evaluated. This criterion requires that the plotted point representing the major-street traffic volume (total of both approaches) and the corresponding minorstreet traffic volume (higher-volume approach, one direction only) during the peak hour of an average day falls above the applicable curve in Figure 4C-3.

The peak hour volume from 3:00 PM to 4:00 PM was plotted on Figure 4C-3 and falls above the applicable curve. Accordingly, Criterion B is met. Hence, warrant 3 is satisfied. Appendix D includes the plotted chart for Peak Hour Warrant 3.

Warrant 4 – Pedestrian Volume
Warrant 4 evaluates the need for a traffic signal based on pedestrian crossing demand at an intersection or midblock location. In accordance with the California MUTCD, 2026 Edition, this warrant assesses whether pedestrian volumes, in combination with vehicular traffic on the major street, create conditions that justify signalization. The evaluation is conducted using the criteria and curves presented in Figures 4C-5 and 4C-6.

Pedestrian activity at the study intersection was observed to be minimal crossing the major street, with a maximum of four pedestrians per hour recorded during the study period. Both Criterion A and Criterion B were evaluated to determine if the warrant is satisfied. Under Criterion A, four peak hours were analyzed, including two hours from 7:00 AM to 9:00 AM and two hours from 4:00 PM to 6:00 PM.

For each of these hours, the total major-street volume (both approaches) was plotted against the corresponding pedestrian volumes crossing the major street. All plotted points fall below the applicable curve; therefore, Criterion A is not met.

Under Criterion B, the peak hour from 5:00 PM to 6:00 PM was evaluated by plotting the total majorstreet volume against the corresponding pedestrian crossing volume. The resulting point also falls below the applicable curve; therefore, Criterion B is not met. Hence, warrant 4 is not satisfied.

Appendix D includes the plotted charts for Pedestrian volume Warrant 4.

Warrant 5 – School Crossing
Warrant 5 evaluates the need for a traffic signal based on the presence of school-aged pedestrians and their ability to safely cross the roadway. In accordance with the California MUTCD, 2026 Edition, this warrant considers the frequency of school crossings, the availability of adequate gaps in traffic, and the proximity of existing traffic control devices.

As noted previously, pedestrian activity at the study intersection is minimal. During the observation period, two schoolchildren crossing were recorded crossing the major street out of which one was crossing within a single hour. Even with the nearest existing traffic signal located more than 300 feet from the study intersection, and the installation of a new signal at this location would not restrict progressive traffic flow, due to a smaller number of schoolchildren crossing, warrant 5 is not satisfied.

Warrant 6 – Coordinated Signal System
Warrant 6 evaluates the need for a traffic signal at locations that can be effectively incorporated into a coordinated signal system. In accordance with the California MUTCD, 2026 Edition, this warrant is 6

typically applicable when the study intersection is located at an appropriate distance, generally, greater than 1,000 feet from an existing signalized intersection to allow for proper signal coordination and progression.

The study intersection is located approximately 645 feet east of the signalized intersection of Middlefield Road and Marsh Road. This distance is less than the minimum spacing typically required for effective coordination within a signal system. Although the adjacent intersection operates as part of a coordinated system with platooned traffic progressing toward the study location, the close proximity limits the feasibility of providing independent signal control while maintaining efficient progression. Based on the insufficient spacing between the two intersections, warrant 6 is not satisfied.

Warrant 7 – Crash Experience
Warrant 7 evaluates the need for a traffic signal based on the frequency and type of crashes at an intersection that may be correctable by signalization. In accordance with the California MUTCD 2026 Edition, this warrant requires that a minimum number of reportable crashes occur within a 12-month period, along with satisfaction of specified traffic volume conditions. Additionally, an adequate trial of alternative safety measures must have been implemented and found ineffective in reducing crash frequency.

Based on the crash data provided for the period from January 1, 2022, through January 31, 2026, a review of the most recent 12-month period identified one reported crash, which occurred on October 10, 2025. This does not meet the minimum requirement of five or more crashes within a 12-month period as specified by the California MUTCD. Furthermore, none of the applicable crash condition thresholds outlined in Table 4C-2 or Table 4C-3 (including angle and pedestrian crashes, or fatal-andinjury crashes) are satisfied.

Although traffic volume conditions under Warrant 1 (Condition A – Minimum Vehicular Volume and Condition B – Interruption of Continuous Traffic) meet at least 80 percent of the required thresholds, the crash frequency requirement is not met. Hence, warrant 7 is not satisfied.

Warrant 8 – Roadway Network
Warrant 8 evaluates the need for a traffic signal based on the functional importance of the roadway within the transportation network and the minimum volume of traffic entering the intersection. In accordance with the California MUTCD, 2026 Edition, this warrant is applied when the intersection involves two major routes that:
• Serves as part of the principal highway network for through traffic, • Functions as a rural or suburban highway outside of, entering, or traversing a city, and • Appears as a major route on an official plan.

At the study intersection, Middlefield Road serves as a major route A satisfies all three criteria of a principal route, including network function, official plan designation, and classification as a rural/suburban highway, while Watkins Avenue does not serve as a major route. Although, entering volumes during the typical weekday peak hour (05:00 PM – 06:00 PM) total 1,598 vehicles per hour, exceeding the 1,000 vehicles per hour minimum threshold, warrant 8 is not satisfied. 7

Warrant 9 – Intersections Near a Grade Crossing
Warrant 9 applies to intersections located in close proximity to a railroad grade crossing. The warrant is intended to address locations where vehicles stopped at an intersection could queue onto the railroad tracks. The warrant is satisfied when a railroad grade crossing is located within 140 feet of a STOP- or YIELD-controlled approach to an intersection, and the traffic volumes during the highest hour of rail activity exceed the thresholds established by the California MUTCD.

This warrant is not applicable to the study intersection because there are no railroad grade crossings in the vicinity of the intersection. Therefore, the criteria for Warrant 9 are not met and no further evaluation was conducted.

A completed traffic Signal Warrant Worksheet for Middlefield Road and Watkins Avenue is contained in Appendix D.

Middlefield Road and Fair Oaks Lane/Palmer Lane
Warrant 1 – Eight-Hour Vehicular Volume
Warrant 1 evaluates whether traffic volumes on the major street and the critical minor street are sufficiently high to justify signalization over an extended period of the day. This warrant considers both individual and combined approach volumes and compares them against thresholds established in the California MUTCD, 2026 Edition. The intent is to identify locations where recurring traffic demand results in operational inefficiencies or delays that may be mitigated through signal control.

Both Condition A (Minimum Vehicular Volume) and Condition B (Interruption of Continuous Traffic) were evaluated for Warrant 1. Based on a comparison of the major-street and critical minor-street volumes to the 100 percent threshold criteria, five hours under Condition A and seven hours under Condition B exceeded the applicable thresholds. Accordingly, the MUTCD requirement of a minimum of eight qualifying hours is not satisfied under Condition A and B. In addition, when comparing the combined approach volumes to 80 percent of the threshold criteria, both Condition A and Condition B recorded more than eight hours exceeding the reduced thresholds. Hence, warrant 1 is satisfied.

Detailed evaluation for Eight Hour Warrant 1 is contained in Appendix C.

Warrant 2 – Four-Hour Vehicular Volume
Warrant 2 evaluates whether traffic volumes during any four hours of an average day are sufficient to justify signalization. In accordance with the California MUTCD, 2026 Edition, this warrant is assessed by comparing the total volume on both approaches of the major street with the higher-volume approach on the minor street. These volumes are plotted against the criteria presented in Figure 4C1, and the warrant is considered satisfied when the plotted points fall above the applicable curve.

As required, four individual hours of traffic volumes were selected and analyzed. The evaluated hours include one hour from 08:00 AM to 09:00 AM, and three hours from 03:00 PM to 06:00 PM. For each of these hours, the total volume on the major street (both approaches) was plotted against the highervolume minor street approach on Figure 4C-1 of the California MUTCD.

All plotted data points fall above the applicable curve. Hence, warrant 2 is satisfied. The plotted chart for Four Hour Warrant 2 is provided in Appendix D.

Warrant 3 – Peak Hour Volume
Warrant 3 evaluates traffic conditions during the single highest hour of an average day to determine whether a traffic signal is justified. In accordance with the California MUTCD, 2026 Edition, this warrant is intended to address locations where minor-street traffic experiences excessive delay when attempting to enter or cross a major street during peak traffic conditions. The analysis is conducted using the criteria and curves presented in Figure 4C-3.

The California MUTCD specifies that satisfying any one of the applicable criteria is sufficient to meet the warrant. For this analysis, Criterion B was evaluated. This criterion requires that the plotted point representing the major-street traffic volume (total of both approaches) and the corresponding minorstreet traffic volume (higher-volume approach, one direction only) during the peak hour of an average day falls above the applicable curve in Figure 4C-3.

The peak hour volume from 3:00 PM to 4:00 PM was plotted on Figure 4C-3 and falls above the applicable curve. Accordingly, Criterion B is met. Hence, warrant 3 is satisfied. Appendix D includes the plotted chart for Peak Hour Warrant 3.

Warrant 4 – Pedestrian Volume
Warrant 4 evaluates the need for a traffic signal based on pedestrian crossing demand at an intersection or midblock location. In accordance with the California MUTCD, 2026 Edition, this warrant assesses whether pedestrian volumes, in combination with vehicular traffic on the major street, create conditions that justify signalization. The evaluation is conducted using the criteria and curves presented in Figures 4C-5 and 4C-6.

Pedestrian activity at the study intersection was observed to be minimal crossing the major street, with a maximum of four pedestrians per hour recorded during the study period. Both Criterion A and Criterion B were evaluated to determine if the warrant is satisfied. Under Criterion A, four peak hours were analyzed, including one hour from 08:00 AM to 09:00 AM and three hours from 03:00 PM to 06:00 PM. For each of these hours, the total major-street volume (both approaches) was plotted against the corresponding pedestrian volumes crossing the major street. All plotted points fall below the applicable curve; accordingly, Criterion A is not met.

Under Criterion B, the peak hour from 5:00 PM to 6:00 PM was evaluated by plotting the total majorstreet volume against the corresponding pedestrian crossing volume. The resulting point also falls below the applicable curve; accordingly, Criterion B is not met. Hence, warrant 4 is not satisfied.

Appendix D includes the plotted charts for Pedestrian volume Warrant 4.

Warrant 5 – School Crossing
Warrant 5 evaluates the need for a traffic signal based on the presence of school-aged pedestrians and their ability to safely cross the roadway. In accordance with the California MUTCD, 2026 Edition, this warrant considers the frequency of school crossings, the availability of adequate gaps in traffic, and the proximity of existing traffic control devices.

As noted previously, pedestrian activity at the study intersection is minimal. During the observation period, two school-aged pedestrians were recorded crossing the major street out of which one was crossing within a single hour. Even with the nearest existing traffic signal located more than 300 feet from the study intersection, and the installation of a new signal at this location would not restrict progressive traffic flow, due to a smaller number of schoolchildren crossing, warrant 5 is not satisfied. 9

Warrant 6 – Coordinated Signal System
Warrant 6 evaluates the need for a traffic signal at locations that can be effectively incorporated into a coordinated signal system. In accordance with the California MUTCD, 2026 Edition, this warrant is typically applicable when the study intersection is located at an appropriate distance, generally, greater than 1,000 feet from an existing signalized intersection to allow for proper signal coordination and progression.

The study intersection is located approximately 985 feet west of the signalized intersection of Middlefield Road and Marsh Road. This distance is less than the minimum spacing typically required for effective coordination within a signal system. Although the adjacent intersection operates as part of a coordinated system with platooned traffic progressing toward the study location, the close proximity limits the feasibility of providing independent signal control while maintaining efficient progression. Based on the insufficient spacing between the two intersections, warrant 6 is not satisfied.

Warrant 7 – Crash Experience
Warrant 7 evaluates the need for a traffic signal based on the frequency and type of crashes at an intersection that may be correctable by signalization. In accordance with the California MUTCD 2026 Edition, this warrant requires that a minimum number of reportable crashes occur within a 12-month period, along with satisfaction of specified traffic volume conditions. Additionally, an adequate trial of alternative safety measures must have been implemented and found ineffective in reducing crash frequency.

Based on the crash data provided for the period from January 1, 2022, through January 31, 2026, a review of the most recent 12-month period identified no reported crash, which occurred on October 10, 2025. In the prior 12-month period there were two reportable crashes recorded in the year 2024 which were broadside collisions correctable by a traffic signal. One was recorded on January 7, 2024, and another was recorded on October 16, 2024. This does not meet the minimum requirement of five or more crashes within a 12-month period as specified by the California MUTCD. Furthermore, none of the applicable crash condition thresholds outlined in Table 4C-2 or Table 4C-3 (including angle and pedestrian crashes, or fatal-and-injury crashes) are satisfied.

Although traffic volume conditions under Warrant 1 (Condition A – Minimum Vehicular Volume and Condition B – Interruption of Continuous Traffic) meet at least 80 percent of the required thresholds, the crash frequency requirement is not met. Hence, warrant 7 is not satisfied.

Warrant 8 – Roadway Network
Warrant 8 evaluates the need for a traffic signal based on the functional importance of the roadway within the transportation network and the minimum volume of traffic entering the intersection. In accordance with the California MUTCD, 2026 Edition, this warrant is applied when the intersection involves two major routes that:
• Serves as part of the principal highway network for through traffic, • Functions as a rural or suburban highway outside of, entering, or traversing a city, and • Appears as a major route on an official plan.
10

At the study intersection, Middlefield Road serves as a major route A satisfies all three criteria of a principal route, including network function, official plan designation, and classification as a rural/suburban highway, while Watkins Avenue does not serve as a major route. Although, entering volumes during the typical weekday peak hour (03:00 PM – 04:00 PM) total 1,334 vehicles per hour, exceeding the 1,000 vehicles per hour minimum threshold, warrant 8 is not satisfied.

Warrant 9 – Intersections Near a Grade Crossing
Warrant 9 applies to intersections located in close proximity to a railroad grade crossing. The warrant is intended to address locations where vehicles stopped at an intersection could queue onto the railroad tracks. The warrant is satisfied when a railroad grade crossing is located within 140 feet of a STOP- or YIELD-controlled approach to an intersection, and the traffic volumes during the highest hour of rail activity exceed the thresholds established by the California MUTCD.

This warrant is not applicable to the study intersection because there are no railroad grade crossings in the vicinity of the intersection. Therefore, the criteria for Warrant 9 are not met and no further evaluation was conducted.

A completed traffic Signal Warrant Worksheet for Middlefield Road and Watkins Avenue is contained in Appendix D.

II – High Intensity Activated Crosswalk (HAWK) Signal Warrant The installation of a HAWK Signal at the study intersections was assessed using Chapter 4J Pedestrian Hybrid Beacons, California MUTCD, 2026 Edition, for Low-Speed Roadways i.e., for roadways with a posted speed limit of 35 mph or less. Table 3 lists the max hourly pedestrian and vehicular volumes as observed from the peak-hour data collection period and presents results on whether a HAWK Signal warrant criteria were met or not.

The total number of pedestrians crossing the major streets at study intersections was less than 20 per hour. Hence, Warrant for pedestrian hybrid beacon is not satisfied.

III – Rectangular Rapid Flashing Beacon (RRFB) Warrant
The installation of RRFB was assessed using IRWL guidelines listed in Section 4U.02 (Line 15) of California MUTCD. For warrant analysis, threshold for pedestrian volumes is 40 or more pedestrians observed in any two hours, and a vehicular volume of more than 200 vehicles observed per hour was considered. The following Table 4 the hourly pedestrian and vehicular volumes as observed during the 11

peak hour data collection period and presents results on whether the RRFB Warrant criteria were met or not.

Even though the vehicular volume exceeds 200 vehicles per hour, the pedestrian crossing volume is fewer than 40 pedestrians within a two-hour period. Hence, Warrant for RRFB is not satisfied.

CONCLUSION
The study intersections of Middlefield Road and Watkins Avenue, and Middlefield Road and Fair Oaks Lane/Palmer Lane met Caltrans Traffic Signal Warrants 1, 2, and 3. Neither of the two intersections met the High Intensity Activated Crosswalk (HAWK) and Rectangular Rapid-Flashing Beacon (RRFB).

The study recommends installation on new traffic signals at Middlefield Road and Watkins Avenue as well as at Middlefield Road and Fair Oaks Lane/Palmer Lane. 12

Chapter 4C – Traffic Control Signal Needs Studies January 18, 2026 Part 4 Highway Traffic Signals
CHAPTER 4C. TRAFFIC CONTROL SIGNAL NEEDS STUDIES
Section 4C.01 Studies and Factors for Justifying Traffic Control Signals Standard:
01 Except for a temporary traffic control signal (see Section 4D.11) installed in a temporary traffic control zone, before a traffic control signal is installed at a particular location, an engineering study of traffic conditions, pedestrian characteristics, and physical characteristics of the location shall be performed to determine whether installation of a traffic control signal is justified at that location. 01a On State highways, the engineering study to evaluate proposed traffic control and design geometrics for intersections and other access improvements shall use Intersection Safety and Operational Assessment Process (ISOAP) and Information Guide. Intersection geometry and traffic control shall be determined through a performance-based analysis that considers all users and supports the principles of the Safe System Approach.

Option:
01b On local streets and highways, the engineering study to evaluate proposed traffic control and design geometrics for intersections and other access improvements may use Intersection Safety and Operational Assessment Process (ISOAP) and Information Guide.

Intersection geometry and traffic control may be determined through a performance-based analysis that considers all users and supports the principles of the Safe System Approach.

Support:
01c Refer to Caltrans’ website (https://dot.ca.gov/programs/traffic-operations/isoap) for more information on the ISOAP memo, guide, forms, related NCHRP publications, and other references and resources for the evaluation of proposed traffic control and design geometrics for intersections and other access improvements.

Standard:
02 The investigation of the need for a traffic control signal shall include an analysis of factors related to the existing operation and safety at the study location and the potential to improve these conditions, and the applicable factors contained in the following traffic signal warrants:

Warrant 1, Eight-Hour Vehicular Volume
Warrant 2, Four-Hour Vehicular Volume
Warrant 3, Peak Hour
Warrant 4, Pedestrian Volume
Warrant 5, School Crossing
Warrant 6, Coordinated Signal System
Warrant 7, Crash Experience
Warrant 8, Roadway Network
Warrant 9, Intersection Near a Grade Crossing
03 The satisfaction of a traffic signal warrant or warrants shall not in itself require the installation of a traffic control signal.

Support:
04 Sections 8D.08 and 8D.14 contain information regarding the use of traffic control signals instead of gates and/or flashing-light signals at grade crossings.

Guidance:
05 When considering the installation of a traffic control signal, alternatives to traffic control signals, including those listed in Section 4B.03, should also be considered.
06 A traffic control signal should not be installed unless one or more of the factors described in this Chapter are met. 07 A traffic control signal should not be installed unless an engineering study indicates that installing a traffic control signal will improve the overall safety and/or operation of the intersection. 08 The study should consider the effects of the right-turning vehicles from the minor-street approaches. Engineering judgment should be used to determine what, if any, portion of the right-turning traffic is subtracted from the minorstreet traffic count when evaluating the count against the signal warrants listed in Paragraph 2 of this Section. 09 Engineering judgment should also be used in applying various traffic signal warrants to cases where major-street approaches consist of one lane plus one left-turn or right-turn lane. The site-specific traffic characteristics should dictate whether a major-street approach is considered as one lane or two lanes. For example, for a major-street approach with one lane for through and right-turning traffic plus a left-turn lane, if engineering judgment indicates that California MUTCD 2026 Edition

Chapter 4C – Traffic Control Signal Needs Studies January 18, 2026 Part 4 Highway Traffic Signals
it should be considered a one-lane approach because the traffic using the left-turn lane is minor, the total traffic volume approaching the intersection should be applied against the signal warrants as a one-lane approach. The major-street approach should be considered two lanes if approximately half of the traffic on the approach turns left and the left-turn lane is of sufficient length to accommodate all left-turning vehicles. 10 Similar engineering judgment and rationale should be applied to a minor-street approach with one through/leftturn lane plus a right-turn lane. In this case, the degree of conflict of minor-street right-turning traffic with traffic on the major street should be considered. Thus, right-turning traffic should not be included in the minor-street volume if the movement enters the major street with minimal conflict. The minor-street approach should be evaluated as a one-lane approach with only the traffic volume in the through/left-turn lane considered.
11 If a minor-street approach has one combined through/right-turn lane plus a left-turn lane, the approach should either be analyzed as a two-lane approach based on the sum of the traffic volumes using both lanes or as a one-lane approach based on only the traffic volume in the approach lane with the higher volume. 12 At a location that is under development or construction or at a location where it is not possible to obtain a traffic count that would represent future traffic conditions, hourly volumes should be estimated as part of an engineering study for comparison with traffic signal warrants. Except for locations where the engineering study uses the satisfaction of Warrant 8 to justify a signal, a traffic control signal installed under projected conditions should have an engineering study done within 1 year of putting the signal into steady (stop-and-go) operation to determine if the signal is justified. If not justified, the signal should be taken out of steady (stop-and-go) operation or removed.

Option:
13 For signal warrant analysis, a location with a wide median may be analyzed as one intersection or as two intersections (see Section 2A.23) based on engineering judgment. Refer to CVC § 21361(a) for designation as a single intersection, for locations on the state highway system. 14 At an intersection with a high volume of left-turning traffic from the major street, the signal warrant analysis may be performed in a manner that considers the higher of the major-street left-turn volumes as the “minor-street” volume and the corresponding single direction of opposing traffic on the major street as the “major-street” volume of the major-street left-turn volumes plus the higher volume minor-street approach as the “minor street” volume and both approaches of the major street minus the higher of the major-street left-turn volume as “major street” volume. 15 For signal warrants requiring conditions to be present for a certain number of hours in order to be satisfied, any four consecutive 15-minute periods may be considered as 1 hour if the separate 1-hour periods used in the warrant analysis do not overlap each other and both the major-street volume and the minor-street volume are for the same specific 1-hour periods.
16 For signal warrant analysis, bicyclists may be counted as either vehicles or pedestrians.

Support:
17 When performing a signal warrant analysis, bicyclists riding in the street with other vehicular traffic are usually counted as vehicles and bicyclists who are clearly using pedestrian facilities are usually counted as pedestrians.

Option:
18 Engineering study data may include the following:

A. The number of vehicles entering the intersection in each hour from each approach during 12 hours of an average day. It is desirable that the hours selected contain the greatest percentage of the 24-hour traffic volume.

B. Vehicular volumes for each traffic movement from each approach, classified by vehicle type (heavy trucks, passenger cars and light trucks, public-transit vehicles, and, in some locations, bicycles), during each 15-minute period of the 2 hours in the morning and 2 hours in the afternoon during which the total traffic entering the intersection is the greatest.

C. Pedestrian volume counts on each crosswalk during the same periods as the vehicular counts in Item B and during the hours of highest pedestrian volume. Where young, elderly, and/or persons with physical or vision disabilities need special consideration, the pedestrians and their crossing times may be classified by general observation.

D. Information about nearby facilities and activity centers that serve the young, elderly, and/or persons with disabilities, including requests from persons with disabilities for accessible crossing improvements at the location under study. These persons might not be adequately reflected in the pedestrian volume count if the absence of a signal restrains their mobility.
