CITY COUNCIL STAFF REPORT
Department: Public Works/Engineering
Meeting Date: February 17, 2026
SUBJECT:

Study Session to Review Traffic Circulation and Safety Improvements at and around the Ivy Drive Neighborhood
EXECUTIVE SUMMARY:

The City Council will hold a study session to consider proposed changes for safety improvements at various intersections near the Ivy Drive Neighborhood, including Moraga Way, Ivy Drive, Coral Drive, Ardith Drive and El Camino Moraga. This study session was at the request of the City Council, following a discussion in July 2025. The City Council requested additional data and a more holistic approach that considered other school safety improvements.

RECOMMENDATION:

Review and provide direction on the following Staff recommendations:

1. Remove the existing “No Left Turn” signs at southbound Moraga Way/Ivy Drive (north) intersection;

2. Change existing time restriction on “No U-Turn/No Left Turn” signs on southbound Moraga Way at Southwaite Court and Whitehall Drive;

3. Install new “No Right Turn” sign at southbound Ivy Drive at Ardith Drive;

4. Modify traffic signal timings at Coral Drive and Ivy Drive (south) intersections on Moraga Way;

5. Add STOP sign and additional striping changes on Coral Drive at Ardith Drive/Court; and

6. Implement NO PARKING restriction on Eastbound El Camino Moraga near the exit driveway at Del Rey Elementary.

BACKGROUND:

Over the last several years, the City received complaints from drivers about the effectiveness of the No Left Turn sign at the intersection of Moraga Way and Ivy Drive (North). The sign was put in place in 2000 because Ivy Drive neighborhood residents expressed concerns about vehicles utilizing Ivy Drive to bypass congestion on Moraga Way and access Miramonte High School.

At its meeting on July 15, 2025, City Council was presented with recommendations from a traffic study to consider removal of the No Left Turn sign and to implement additional Item C.1
Packet Page 4
traffic calming measures in the Ivy Drive Neighborhood to improve traffic safety and circulation.

Based on feedback received during public comments, the City Council directed staff to gather additional data and bring the item back to a City Council study session.

Two additional requests were received for other traffic related concerns in the vicinity of Ivy Drive, at Coral Drive and El Camino Moraga. Studies were conducted at these two locations, recommendations of which are also being presented for City Council consideration.

DISCUSSION:

Ivy Drive Circulation Study:

The City contracted with traffic consultant AMG to prepare a technical memorandum to supplement the December 8, 2024, Moraga Way Circulation Studies (Attachment B & C) to document the results of a license plate recognition (LPR)–based origin–destination (OD) analysis. The purpose of the supplemental analysis is to evaluate cut-through traffic patterns using LPR data, confirm the temporal and directional trends identified in the previous StreetLight Insight analysis, and quantify the real-world share of cut-through trips between key roadway segments during the weekday a.m. peak period. Circulation study counts were collected on Tuesday, August 26, 2025.

Turning movement counts were collected on Thursday, September 9, 2025, between 7:00 a.m. and 9:00 a.m., at three key intersections along Moraga Way (Moraga Way & Ivy Drive North, Moraga Way & Coral Drive, and Moraga Way & Ivy Drive South). These intersections serve as the primary access points into and out of the neighborhood surrounding Orinda Intermediate School (OIS).

Recommendations:

Findings from the additional data reinforces the prior recommendations to remove the No Left Turn restriction, supported by targeted operational improvements along Moraga Way and Ivy Drive. This approach will provide a balanced strategy that enhances arterial function, discourages cut-through traffic, supports school access needs, and improves overall safety and predictability within the corridor. Additional recommendations include:

1. Implement Signal Coordination and Timing Improvements on Moraga Way Enhance signal coordination along Moraga Way to reduce delay and improve traffic progression. When the arterial operates efficiently, drivers are more likely to remain on Moraga Way rather than divert through Ivy Drive or Ardith Drive.

Improved travel times and fewer stops along Moraga Way will make it the preferred route for through traffic.

2. Increase Delay at the Ivy Drive and Coral Drive Signal Introduce additional delay at the Ivy Drive and Coral Drive intersection during the morning peak hour to discourage cut-through traffic. By making the neighborhood route less advantageous, this adjustment helps shift non-school traffic back to Item C.1
Packet Page 5
Moraga Way while still maintaining access for residents and school-related vehicles.

3. Support Safer and More Predictable School Access
Removing the No Left Turn restriction accommodates the substantial number of vehicles directly accessing OIS. Allowing this movement legally eliminates unsafe and unpredictable maneuvers associated with drivers violating the restriction and helps maintain a safer and more orderly school drop-off environment. Additional operational improvements include adjusting the time restriction on “No U-Turn/No Left Turn” signs on southbound Moraga Way at Southwaite Court and Whitehall Drive to better match the school drop off times, and adding a “No Right Turn” sign at southbound Ivy Drive at Ardith Drive to deter Miramonte High School cut-through traffic.

Analysis of All-Way Stop Control Warrants and Safety:

The City received a request from the community to install an all-way stop control at Coral Drive and Ardith Drive intersections. There are currently stop signs on Ardith Drive and Ardith Court, but not on Coral Drive. Due to the proximity of this intersection to Ivy Drive and the significant traffic circulation that goes through here, a stop sign warrant analysis was performed (Attachment D). The warrant analysis was based on the criteria in the California Manual on Uniform Traffic Control Devices (CA-MUTCD). Although the intersection did not meet all-way stop control warrants that include the collision warrant, volume warrant or combination warrant, it did meet the optional warrant for visibility based on the limited sight distance. Based on meeting the optional warrant and engineering judgment, Staff recommends converting this intersection to an all-way or 4-way STOP controlled. The study also recommended relocating the STOP bar on Ardith Drive by 10 feet to the north and to stripe edge lines and a centerline with 10-foot travel lanes on Coral Drive between Moraga Way and Ardith Drive/Court to improve pedestrian safety, which Staff also supports.

Evaluate Traffic Circulation at Del Rey Elementary:

The City received a request to review parking on El Camino Moraga adjacent to Del Rey Elementary due to significant safety and circulation related traffic issues observed during school drop-off and pick-up. El Camino Moraga currently has parking restrictions on the west side of the street, but parking is allowed on the east side. Vehicles parked in the area adjacent to the Del Rey Elementary exit driveway severely impact traffic flow during school pick up and drop off and can potentially affect circulation on Moraga Way. Vehicles parked in the area block the pedestrian access along El Camino Moraga between the entrance and exit to the school. Staff support the study’s recommendation to implement NO PARKING restrictions immediately adjacent to the exit driveway, on both sides to improve circulation and safety at Del Rey Elementary. See study in Attachment E.

FISCAL IMPACT:

The cost for implementing the proposed changes is estimated to be about $7,000 plus Staff time for procurement and managing the project, plus ongoing maintenance expenditure of installation and removal of the restricted turn movement signs at the beginning and end of each school year. There are sufficient funds available under Traffic Item C.1
Packet Page 6
Calming and Pedestrian Safety Program (CIP # 4107) budget, which is funded by Fund #200, Gas Tax.

STRATEGIC PLAN INITIATIVE:

2.d – Focus on capital projects that enhance circulation, mobility, and transportation and improve road safety overall.

Email: [email protected] Date: February 5, 2025 Subject: Moraga Way Circulation Studies: Supplemental Intersection and Timing Analysis Introduction
This technical memorandum supplements the Circulation Study near Ivy Drive and Ardith Drive performed in December 2024. This document expands the previous study by performing a detailed intersection operational analysis at seven intersections along Moraga Way, which includes four stopcontrolled and three signalized intersections from Ivy Drive (North) to Ivy Drive (South). Existing intersection delays, signal timing, and field observations were reviewed, and recommendations that address both operational and safety concerns are discussed. The study intersections are as follows:

1. Moraga Way & Ivy Drive (North)

2. Moraga Way & Southwaite Court

3. Moraga Way & El Camino Moraga (Signalized Intersection)

4. Moraga Way & Whitehall Drive

5. Moraga Way & Coral Drive (Signalized Intersection)

6. Moraga Way & Eastwood Drive

7. Moraga Way & Ivy Drive (South) (Signalized Intersection) An additional study, titled Supplemental LPR Cut-Through Analysis was performed concurrently and analyzed the extent of cut-through traffic using License Plate Recognition data in the vicinity of Orinda Intermediate School.

Existing Synchro Analysis and Observations
Synchro, a traffic and signal timing analysis tool, was used to model all three signalized intersections and four stop controlled intersections. Recent signal timings and turning movement count data were populated in the model. The existing conditions operational performance were analyzed using the Highway Capacity Manual (HCM) methodology and field/SimTraffic simulation observations. The stopcontrolled intersections were evaluated using HCM 7th Edition, which is the most recent analysis methodology. The signalized intersections were evaluated with HCM 2000 due to the non-standard phasing in use at all three signalized intersections. Appendix A shows the traffic count data for each Item C.1

intersection, which was collected on September 9th, 2025. This section describes the existing operation of the study intersections, and the following section describes the proposed recommendations.

Moraga Way & Ivy Drive (North)
A steady stream of vehicles traveling on Moraga Way resulted in high delays for vehicles turning onto Moraga Way at this one-way stop-controlled (OWS) intersection. The stop-controlled approach currently operates at LOS F. Turning movement counts at the intersection revealed that 369 vehicles turn left from the southbound direction during the a.m. peak hour which was observed to be between 7:45 a.m. and 8:45 a.m. During the time that left turns are restricted (7:00 a.m. to 8:00 a.m.), 98 vehicles made the left turn. The southbound left movement operates at LOS B, indicating insignificant delay.

Moraga Way & Southwaite Court
No operational issues were noted at this one-way stop-controlled intersection. The stop-controlled approach operates at LOS C. The southbound left turn volume was light for the duration of the data collection period. There is currently a “No Left Turn” at this intersection with turns restricted from 7 a.m. to 8 a.m.

Moraga Way & El Camino Moraga
No major operational issues were noted at this signalized intersection. Delays varied depending on whether a pedestrian call was being served (pedestrians are served with an exclusive phase) and vehicle demand but remained moderate throughout the morning period. Occasionally, the southbound phase terminated while vehicles were still arriving to serve a handful of vehicles for the northbound left movement. This increased the delay for several southbound vehicles only to serve 1 or 2 northbound left vehicles. The intersection operates at LOS C, with the northbound left and eastbound directions at LOS D.

Moraga Way & Whitehall Drive
Approximately 20 vehicles during the peak hour of 7:45 a.m. to 8:45 a.m. made a southbound-left turn onto Whitehall Drive, which is currently prohibited from 7 a.m. to 8 a.m. Only two vehicles made the left turn during the restricted period. Given that there is no left turn pocket, occasionally a vehicle intending to go straight in the southbound direction gets delayed because the vehicle in front intends to turn left and needs to find an acceptable gap. This occasionally blocks the southbound movement on Moraga Way, causing additional delays along the corridor. The stop-controlled approach operates at LOS D.

Moraga Way & Coral Drive
Side street delays were occasionally high while platoons of vehicles passed the intersection while delays for though movements were moderate. It was observed that drivers intending to make a southbound left turn blocks following through vehicles, causing additional delays. 44 vehicles made the left turn onto Coral Drive during the peak hour, which was from 7:45 a.m. to 8:45 a.m. There is currently no “No Left Turn” sign at this intersection. 31 pedestrians used the crosswalk during the peak hour, indicating Item C.1

extensive crosswalk usage. The crosswalks operate under an exclusive phase, which may increase pedestrian safety, but requires all vehicles to stop. The intersection operates at LOS B and the side street operates at LOS E.

Moraga Way & Eastwood Drive
This intersection is one-way stop controlled and has a Rapid Rectangular Flashing Beacon (RRFB) for the pedestrian crosswalk across Moraga Way. The peak hour left turn volume was 8 vehicles. No operational issues were noted at this intersection. The stop-controlled approach operates at LOS C.

Moraga Way & Ivy Drive (South)
It was observed that the southbound through movement terminates early while there is still traffic arriving at the signal. This creates additional delays for the southbound movement, which is the movement that can be improved to provide a faster route than cutting through Ivy Drive. Additionally, the maximum green times set in the controller are high for all phases which resulted in long cycle lengths, delays, and queuing, including for phases along Moraga Way.

It was also observed that there is a long queue for the southbound right turn movement at the intersection. Due to the long queue for that movement, drivers are impatient and try to make that movement as soon as they can. However, due to the large numbers of pedestrians using the conflicting crosswalk while it is also green for that movement, there was a potential conflict for pedestrians getting hit by impatient drivers. The intersection operates at LOS C.

Recommendations
The main goals of the recommendations are to improve the signal timing for vehicles traveling on Moraga Way so that it is a faster route compared to Ivy Drive. While the posted speed limit will not increase, the delays experienced by drivers on Moraga Way should decrease, which should increase the average travel speed to be closer to the speed limit. Recommendations focus on signal timing modifications including signal coordination and the update of timing parameters based on MUTCD standards, possible signal modifications, and possible geometric changes.

Implementing coordination is expected to improve operations and safety for the three signalized intersections for the following reasons:
• Non-stop vehicle progression is possible in both directions with steady demand on all vehicle and pedestrian phases.
• Travel time will be reduced, resulting in a faster trip compared to using Ivy Drive. • Safer for pedestrians because few vehicles arrive during the pedestrian phases crossing Moraga Way (vehicles arrive right as the green turns on).
• Reduced speeding because vehicles travel in platoons with the first vehicles traveling at the speed limit because the green will not turn on early for speeding drivers.

Implementing signal coordination along Moraga Way is expected to reduce congestion on Moraga Way and thereby eliminating the need for drivers to cut through Ivy Drive. Currently, drivers are making a left turn where there is no left turn pocket (such as at Whitehall Drive), which creates delays for following vehicles and increases the likelihood of rear-end collisions. By allowing vehicles to make the left turn at Ivy Drive (North), we can expect fewer vehicles to make left turns at Whitehall Drive and Coral Drive.

Moraga Way & Ivy Drive (North)
For recommendations at Ivy Drive (North), please see the concurrently released Supplemental LPR CutThrough Analysis, which includes an in-depth origin-destination study throughout the area.

For recommendations at Southwaite Court, please see the concurrently released Supplemental LPR Cut-Through Analysis, which includes an in-depth origin-destination study throughout the area.

Moraga Way & El Camino Moraga
Timing changes reflect slightly more preference to the southbound phase compared to the northbound left phase. The minimum green times and yellow times are suggested to be increased slightly to meet CA MUTCD minimum requirements. Coordination timing is recommended and is expected to greatly decrease travel time for through running vehicles, while not increasing the existing cycle length.

Moraga Way & Whitehall Drive
If a left turn pocket is installed at Coral Drive (see next section), the number of vehicles that will make a left turn at this intersection may decrease since a more convenient left turn option exists 1,200 feet down the road at Coral Drive. Whitehall Drive and Coral Drive lead both lead to Ardith Drive, indicating drivers can choose either Whitehall Drive or Coral Drive to make a southbound left turn. Additional recommendations for Whitehall Drive are discussed in the Supplemental LPR Cut-Through Analysis.

Moraga Way & Coral Drive
The signal timing parameters are adjusted to more effectively prioritize vehicles on Moraga Way. The minimum green times and yellow times are suggested to be increased slightly to meet CA MUTCD minimum requirements. In an attempt to reduce cut-through traffic, the side street phase delay may increase slightly, as recommended by the Supplemental LPR Cut-Through Analysis.

Coordination timing is recommended and is expected to greatly decrease travel time for throughrunning vehicles and maintain a moderate cycle length. A short left-turn pocket can help reduce delays due to southbound left traffic blocking southbound through traffic. There may be space if the bus stop is relocated to the nearside of the intersection in the northbound direction.

This intersection is operating effectively, and no recommendations are made.

Moraga Way & Ivy Drive (South)
Changes to the maximum green times are suggested for the AM, off-peak, and PM time periods. The goal is to lower the actuated cycle length during heavy periods and to give a slightly greater proportion of time to Moraga Way. The existing timing sheet uses Max Limit (1) green time all day and night except for 3:00 pm to 4:30 pm when Max Limit 2 is in effect. The Max Limit 2 values are significantly higher than the Max Limit 1. While the afternoon school period was not analyzed for this study, it is recommended to use the Max Limit 2 values during AM and PM school times and use Max Limit 1 at other times of day. Both maxes were adjusted to result in reasonable fully actuated cycle lengths at all times of day, with a slightly higher cycle length during school times. By redistributing time and lowering the maximum cycle length, overall delays and queues are expected to decrease. The time assigned to Ivy Drive (coming from OIS) was slightly decreased to create a longer delay for this cutthrough approach. The timing changes also reflect slightly higher preference to the southbound vehicle movement along Moraga Way. The yellow times are suggested to be increased slightly to meet CA MUTCD minimum requirements.

Coordination timing is recommended and is expected to greatly decrease travel time for throughrunning vehicles and while not increasing the cycle length. To improve safety for the crosswalks with the most pedestrians, “No Right Turn” blank out signs can be installed and can be illuminated during the Walk interval, which is typically 7 seconds in duration. The goal of these signs is to draw attention to pedestrians in the crosswalk. These signs will only illuminate when a pedestrian phase is served, so drivers will be able to make a right turn on red during other phases when safe. An example of this operation is shown in Figure 1. These signs are recommended to be placed for vehicles making a southbound right turn from Moraga Way heading toward Miramonte High School and for vehicles making an eastbound right turn from Ivy Drive (Miramonte High School) heading toward Moraga.

Figure 1: No Right Turn During Pedestrian Phase (Image credit: San Diego Tribune) Curb extensions or bulb outs on the north, east, and west corners can reduce the pedestrian crossing time and distance. Also, this additional space created by the bulb outs for pedestrians gives them more Item C.1

space to congregate while they wait for the signal. Additionally, the waiting position for pedestrians is more visible to drivers, which may eliminate the need for a Leading Pedestrian Interval (LPI). An LPI is faster to implement and can improve safety in the near term before the geometric changes are made.

The south leg crosswalk crossing Moraga Way is proposed to shift slightly due to the bulb out, which reduces the length and provides better pedestrian visibility to drivers. Approximate locations of the bulb outs and crosswalk are shown in Figure 2.

Analysis of Proposed Conditions
Two scenarios were created in Synchro consisting of existing conditions and recommended improvements. The level of service for the existing and recommended improvements scenarios are similar for each of the intersections with no significant difference in delay according to the Highway Capacity Manual methodology. Using the HCM methodology, individual movement delays remained similar because actuated phase duration times and cycle lengths remained similar for each scenario, which is the basis of the methodology. Since specific controller parameters (such as gap times) are not incorporated in the HCM methodology, the proposed timing changes are expected to marginally improve intersection operations. The recommended improvements have safety benefits because the timing parameters were brought into compliance with CA MUTCD standards and geometric changes were included.

Signal coordination improves the overall arterial travel time, as shown in Table 1. Travel times on Moraga Way between El Camino Moraga and Ivy Drive (South) reduce from 3 minutes and 15 seconds to 2 minutes and 52 seconds in the northbound direction and from 3 minutes and 35 seconds to 3 minutes and 2 seconds. Travel time benefits can bring additional safety benefits by reducing traffic on neighborhood local streets. Appendix C shows the Synchro HCM and Arterial LOS reports.

Conclusion
Implementing timing and intersection geometry recommendations are expected to improve safety and improve operations along Moraga Way. Signal coordination is expected to reduce the travel time along Moraga Way by 20-30 seconds per vehicle, which is expected to reduce cut-through traffic by making Moraga Way a faster route compared to Ivy Drive. Additionally, at Ivy Drive (South), “No Right Turn” blank out signs, pedestrian bulb outs, and a shifted crosswalk aim to draw driver’s attention to pedestrians in the crosswalk. Table 2, below, summarizes the recommendations.

This technical memorandum supplements the Circulation Study near Ivy Drive and Ardith Drive by documenting the results of a License Plate Recognition (LPR)–based Origin–Destination (OD) analysis.

The purpose of this supplemental analysis is to evaluate cut-through traffic patterns using LPR data, confirm the temporal and directional trends identified in the previous StreetLight Insight analysis, and quantify the real-world share of cut-through trips between key roadway segments during the weekday a.m. peak period. The weekday a.m. peak period analyzed coincides with nearby school start times:
approximately 8:00 a.m. at Del Rey Elementary, 8:30 a.m. at Miramonte High School, and 8:45 a.m. at Orinda Intermediate School (OIS), all of which directly influence morning traffic patterns along Ivy Drive and Ardith Drive. Orinda Intermediate School has a Zero Period every day except Fridays that starts at 7:50 a.m.

StreetLight Insight OD Analysis
The StreetLight analysis conducted for the original report used the Origin–Destination with Gates function to estimate trip movements between Ivy Drive (North), Ivy Drive (South), Coral Drive, Ardith Drive, and the Orinda Intermediate School (OIS) Driveway. StreetLight’s platform applies anonymized mobile device and GPS data to infer trip volumes, directions, and temporal distributions.

For each 15-minute interval between 7:15 a.m. and 9:30 a.m., the tool reported modeled trip volumes entering and exiting the defined gates. Cut-through trips were defined as those entering the corridor from Ivy Drive (North) and the OIS Driveway and exiting via another downstream gate (Ivy Drive South, Ardith Drive, or Coral Drive). The resulting dataset was normalized by the total number of cut-through trips during the period to obtain the share of total cut-throughs by time slot.

During the AM Peak hour (7:45 a.m.-8:45 a.m.) the average number of cut-through trips was 94 out of a total of 397 vehicles (24%) on Ivy Drive towards Coral Drive and the southern limit of Ivy Drive. It was also observed that while the percentage of cut-through trips is substantial during that AM Peak hour, the percentage of cut-through trips is reduced to 0% after 9:15 a.m., showing that there is a definite Item C.1

License Plate Recognition (LPR) OD Analysis
To validate and supplement these findings, manual origin–destination (OD) data were collected by recording the last four digits of vehicle license plates at four strategic locations along the corridor:
• Ivy Drive (North)
• Orinda Intermediate School (OIS) Driveway
• Ardith Drive
• Ivy Drive (South)
Observers recorded time-stamped license plate digits between 7:00 a.m. and 9:00 a.m. Cut-through trips were identified by matching license plate digits observed at both an upstream and downstream gate. Each unique match represented one verified cut-through trip.

Manual intersection observers also collected turning movement counts to confirm the directionality and volume trends indicated by the OD matching process.

Ivy Drive – Cut Through Analysis
Ivy Drive is a two-lane residential roadway
connecting Moraga Way (North) to Moraga Way
(South) and provides direct access to Orinda
Intermediate School (OIS), resulting in high traffic
volumes during school drop-off and pick-up periods.

The analyzed segment was between Ivy Drive North
& Moraga Way and Ivy Drive South & Moraga Way.

The cut-through analysis was conducted using
License Plate Recognition (LPR) data, with the start
gate located at Ivy Drive & Moraga Way (North) and
the exit gate at Ivy Drive & Moraga Way (South).

This setup captured vehicle travel patterns through
Ivy Drive to identify cut-through movements.

A total of 415 vehicles were recorded during the
peak period at the Ivy Drive North entry point, of
which 105 trips (approximately 25%) were identified
as cut-through traffic using Ivy Drive to bypass
congestion on Moraga Way. The analysis was
performed to evaluate the effectiveness of existing
No Left Turn restrictions and to assess whether
additional measures were needed to reduce schoolrelated cut-through traffic and improve safety near Orinda Intermediate School.

Findings – Ivy Drive
• Total matched plates: 105
• Peak cut-through window: 7:15 to 8:15 a.m. (percentage of cut through ranges between 36% - 47%)
• Highest 15-minute share: 47% between 7:30 and 7:45 a.m.

StreetLight and License Plate Recognition (LPR) data both show that cut-through activity on Ivy Drive is concentrated during the morning school arrival period. While the two datasets differ in collection methods, they display consistent overall trends, with the LPR data capturing an earlier and more defined peak. The highest cut-through percentage, 47 percent, occurred between 7:30 and 7:45 a.m.

Vehicles accessing the OIS driveway are not included in the cut-through totals.

Cut-through traffic increases noticeably between 7:15 and 8:15 a.m. Drivers continue to make the left turn from Moraga Way onto Ivy Drive during this period despite the existing restriction, indicating that the No Left Turn regulation is not effective.

These findings show the need to remove the No Left Turn restriction during the morning peak hour to accommodate the 109 school-bound vehicles that rely on this movement and to eliminate unsafe behaviors associated with violating the restriction. Cut-through activity identified in the data can be managed through signal coordination and operational adjustments along Moraga Way, along with increased delays at Ivy Drive and Coral Drive to reduce the attractiveness of the neighborhood bypass route.

Ardith Drive – Cut Through Analysis
Ardith Drive is a two-lane residential
roadway that connects Ivy Drive to Coral
Drive and provides an indirect alternate
route between the northern and southern
sections of Moraga Way. The corridor is
often used by drivers attempting to bypass
congestion on Moraga Way during the
morning school drop-off period for Orinda
Intermediate School (OIS) and Miramonte
High School.

The cut-through analysis was conducted
using License Plate Recognition (LPR) data
between Ivy Drive & Ardith Drive (start
gate) and Ardith Drive & Coral Drive (exit
gate). This setup was designed to capture
vehicles traveling through Ardith Drive
without stopping, in order to evaluate the
extent of bypass traffic using this local
street instead of Moraga Way.

Of the same 415 vehicles recorded at the
Ivy Drive North entry location, 118 trips
(approximately 28%) were identified as cut-through movements that diverted via Ardith Drive and Coral Drive to rejoin Moraga Way, contributing to neighborhood congestion and safety concerns.

Findings – Ardith Drive
• Total matched plates: 118
• Peak cut-through window: 7:45 to 8:30 a.m.
• Highest 15-minute share: 41 percent between 7:45 and 8:00 a.m and another 41 percent between 8:00 and 8:15 a.m.

StreetLight and License Plate Recognition (LPR) data both identify the morning school arrival period as the primary window of cut-through activity on Ardith Drive. The LPR data captures a more pronounced peak, with cut-through percentages increasing notably after 7:45 a.m. and continuing through 8:45 a.m., which is consistent with drivers attempting to avoid school-related congestion on Ivy Drive. The OIS school bell time is 8:45 a.m.

The highest cut-through levels recorded in the table occur in the LPR dataset between 7:45–8:00 a.m. (41%) and 8:00–8:15 a.m. (41%), indicating a strong concentration of bypass activity during these periods. StreetLight data similarly shows elevated cut-through percentages between 7:45–8:15 a.m. (20% to 26%). Together, the datasets show that cut-through traffic steadily increases after 7:45 a.m. and remains elevated through 8:15 a.m., with activity in both datasets decreasing after this point.

These findings show that cut-through activity on Ardith Drive is concentrated in a peak window roughly between 7:45 and 8:45 a.m., with the highest cut-through percentages appearing when congestion near the school is greatest. The timing and magnitude of these increases demonstrate that the existing No Left Turn restriction at Moraga Way and Ivy Drive is not preventing diversion, as drivers simply reroute to Ardith Drive when Ivy Drive becomes congested.

The documented behavior supports the need to remove the No Left Turn restriction and instead manage traffic through corridor-level operational adjustments that reduce congestion on Moraga Way.

Improving the arterial flow decreases the incentive for drivers to divert to either Ivy Drive or Ardith Drive, helping to reduce neighborhood cut-through activity during the school arrival period.

Comparison of StreetLight and LPR Analysis
Table 4 summarizes the comparison between the two methodologies used to evaluate cut-through traffic on Ivy Drive and Ardith Drive. StreetLight and License Plate Recognition (LPR) analyses rely on different data collection methods, yet both provide a consistent and comparable depiction of travel behavior in the study area. StreetLight estimates regional travel movements using modeled GPS and mobile device data, while LPR provides direct, site-specific observations of vehicles traveling through the monitored locations.

Item C.1
Packet Page 77
Despite differences in data resolution and sampling, both datasets identify the same morning school arrival period as the primary window of cut-through activity on Ivy Drive and Ardith Drive. The peak cut-through percentages occur before the Orinda Intermediate School (OIS) 8:45 a.m. bell time, reflecting diversion in response to morning congestion near the school. StreetLight and LPR results differ in magnitude due to methodological differences, but both clearly show elevated activity between 7:15 and 8:15 a.m. on Ivy Drive and between 7:45 and 8:45 a.m. on Ardith Drive.

The LPR data consistently shows more defined peaks, such as the 47 percent peak on Ivy Drive (7:30– 7:45 a.m.) and 41 percent peaks on Ardith Drive (7:45–8:00 a.m. and 8:00–8:15 a.m.), compared with StreetLight peaks in the 17–27 percent range. The similarity in timing across both datasets confirms that school schedules directly shape the morning traffic patterns, and that the periods of diversion are captured reliably by both methodologies.

Orinda Intermediate School (OIS) Driveway Circulation Analysis To better understand school-related
circulation patterns along Ivy Drive, a
focused License Plate Recognition (LPR)
analysis was conducted between the OIS
school driveway and the north end of Ivy
Drive at Moraga Way. The analysis
captured inbound movements from Ivy
Drive North toward the school driveway.

The purpose of this study was to quantify
the number and timing of vehicles
entering the OIS driveway and determine
how much of the corridor’s overall traffic
is related to school drop-off activity
compared with cut-through movements.

Inbound Movements – Ivy
Drive North & Moraga Way to
OIS Driveway
The inbound LPR analysis shows that a
significant share of the southbound traffic
approaching Ivy Drive during the morning period is directly related to school activity. Between 7:00 and 9:00 a.m., 415 vehicles made the left-turn movement from Moraga Way onto Ivy Drive. Of these, 109 vehicles entered the OIS driveway, while 223 vehicles used Ivy Drive and Ardith Drive as cut-through routes to bypass congestion on Moraga Way (118 via Ardith Drive and 105 via Ivy Drive). The remaining vehicles either entered the neighborhood or dropped off students along Ivy Drive without entering the school driveway.

The left turn serves an essential function for school access, and a substantial portion of drivers violate the existing No Left Turn restriction to avoid delays on Moraga Way. This combination demonstrates that the current restriction is not effective and does not align with actual travel behavior during the school arrival period. Removing the restriction would reduce illegal maneuvers, improve operational consistency, and provide a direct and appropriate connection to the school during the morning drop-off window.

Summary
The LPR analysis of inbound traffic to the Orinda Intermediate School (OIS) driveway from Ivy Drive North and Moraga Way shows that school-related activity increases steadily through the morning, with the highest levels occurring immediately before the OIS 8:45 a.m. bell time. Of the 415 vehicles traveling southbound on Ivy Drive during the study period, 109 entered the OIS driveway, confirming that a substantial portion of inbound traffic is directly associated with school drop-off activity. Driveway entries remain minimal before 7:30 a.m. (one vehicle per interval), then rise between 7:30 and 8:00 a.m. (5 to 13 vehicles). Volumes increase more notably from 8:00 to 8:15 a.m. (25 vehicles) and from 8:15 to 8:30 a.m. (39 vehicles). A final surge occurs between 8:30 and 8:45 a.m. (24 vehicles), coinciding with last-minute arrivals prior to school start time. This pattern closely matches the broader cut-through and circulation trends on Ivy Drive and Ardith Drive, demonstrating the strong influence of school drop-off activity on congestion and routing behavior within the corridor.

Table 6 summarizes the key components influencing corridor operations during the morning peak, including the number of vehicles making the left turn at Ivy Drive, the corresponding cut-through volumes on Ivy Drive and Ardith Drive, the number of vehicles entering the OIS driveway, and the combined cut-through percentage for each 15-minute interval. This table illustrates how school-related traffic, cut-through behavior, and left-turn activity interact throughout the peak period and provides a consolidated view of the factors shaping morning circulation.

Turning Movement Counts (TMCs) were also reviewed to support the LPR analysis and to better understand how many vehicles enter and exit the neighborhood during the morning peak hour. The TMC data helps confirm the magnitude and direction of traffic flow observed in the cut-through analysis and provides additional context for developing appropriate recommendations.

Item C.1
Packet Page 81
The counts were conducted on September 9, 2025, between 7:00 a.m. and 9:00 a.m., at three key intersections along Moraga Way: Moraga Way & Ivy Drive North, Moraga Way & Coral Drive, and Moraga Way & Ivy Drive South. These intersections serve as the primary access points into and out of the neighborhood surrounding Orinda Intermediate School.

Across the three locations, the TMCs recorded a total of 620 inbound movements and 772 outbound movements during the two-hour period. The highest inbound volumes were observed at Ivy Drive North (454 vehicles in), followed by Coral Drive (92 vehicles in) and Ivy Drive South (74 vehicles in).

Outbound volumes showed a similar pattern, with 346 outbound at Ivy Drive North, 236 at Coral Drive, and 190 at Ivy Drive South. These traffic volumes demonstrate the significant level of circulation occurring through the neighborhood during the morning period and align with the patterns identified through the LPR cut-through analysis.

The TMC results confirm the high level of activity entering the neighborhood during the school arrival window and reinforce the LPR findings by showing how traffic distributes across the three access points. Together, these datasets provide a comprehensive understanding of corridor operations and support the development of targeted recommendations to address school traffic and cut-through behavior.

Recommendations
Based on the evaluation of morning peak traffic conditions, school-related travel patterns, and observed cut-through activity documented through both StreetLight Insight and License Plate Recognition (LPR) origin–destination analyses, intersection-specific operational recommendations have been developed to address recurring congestion, cut-through behavior, and safety concerns within the Ivy Drive and Ardith Drive neighborhood corridors. Both datasets consistently identify the morning school arrival period as the primary window of cut-through activity, with demand increasing sharply between approximately 7:15 a.m. and 8:45 a.m. This period corresponds with overlapping school start times at Del Rey Elementary, Miramonte High School, and Orinda Intermediate School (OIS), including OIS Zero Period beginning at 7:50 a.m. and the main bell time at 8:45 a.m.

Moraga Way & Ivy Drive (Northbound)
• Serves as the primary access point for Orinda Intermediate School (OIS), with 415 vehicles making the left-turn movement during the morning period and 109 vehicles entering the OIS driveway.
• The existing No Left Turn restriction is frequently violated and does not align with peak cutthrough activity, which occurs between 7:15 and 8:15 a.m. • Removal of the No Left Turn restriction is recommended to accommodate school access and reduce illegal turning movements.

Moraga Way & El Camino Moraga
• Functions as a key corridor intersection influencing progression and delay along Moraga Way.

Item C.1
Packet Page 82
• Congestion at this location contributes to diversion onto Ivy Drive and Ardith Drive during the morning peak.
• Evaluation of signal timing and coordination improvements is recommended to improve corridor operations and reduce diversion; timing recommendations are provided in the supplemental Intersection and Timing analysis report.

Moraga Way & Southwaite Drive
• Functions as a neighborhood access point where left turns during the morning peak contribute to conflicts and diversion.
• Existing restriction times do not fully align with peak cut-through activity, which extends to approximately 8:30 a.m.
• Modifying the No Left Turn restriction to 7:30 a.m. – 8:30 a.m. is recommended to better target peak school arrival conditions.

Moraga Way & Whitehall Drive
• Similar neighborhood access point where left turns contribute to cut-through movements during the morning peak.
• Adjusting the No Left Turn restriction to 7:30 a.m. – 8:30 a.m. is recommended to align with peak cut-through activity and reduce conflicts.

Moraga Way & Coral Drive
• Acts as a primary exit point for cut-through traffic using Ardith Drive, with approximately 28 percent of observed vehicles diverting through this route. • Peak cut-through activity occurs between 7:45 and 8:15 a.m., coinciding with peak schoolrelated congestion. • Evaluation of signal timing parameter adjustments and geometric improvements is recommended to discourage cut-through movements and improve mainline operations; refer to the supplemental Intersection and Timing analysis report.

Moraga Way & Ivy Drive (Southbound)
• Peak cut-through activity occurs earlier, between 7:30 and 7:45 a.m. • Evaluation of signal timing parameter adjustments and geometric improvements is recommended to discourage diversion and improve overall intersection safety; refer to the supplemental Intersection and Timing analysis report.

Ivy Drive & Ardith Drive
• Serves as a key internal neighborhood connection with the highest observed cut-through volumes, reaching 41 percent during peak 15-minute intervals.

Item C.1
Packet Page 83
• Cut-through activity increases after 7:45 a.m. and remains elevated through approximately 8:15 a.m.
• Installation of a No Right Turn restriction from 7:30 a.m. – 8:30 a.m. is recommended to limit neighborhood circulation and deter cut-through movements.

The intersection-specific recommendations are summarized in Table 7 and are intended to respond directly to the documented cut-through patterns identified through StreetLight Insight, LPR origin– destination analysis and turning movement counts. Together, these measures are designed to improve school access, reduce unsafe and inefficient diversion behavior, and support overall corridor operations along Moraga Way during the morning peak period.

Conclusion
Collectively, these findings indicate that the existing No Left Turn restriction from Moraga Way onto Ivy Drive (north), currently in effect from 7:00 to 8:00 a.m., does not align with the period of highest cutthrough activity on neighborhood streets. The most significant diversion occurs after 7:15 a.m. and remains elevated until approximately 8:15 a.m., extending beyond the current restriction window. The high frequency of observed violations further indicates that the restriction is not effectively managing neighborhood traffic and contributes to unsafe and unpredictable turning movements.

Removal of the No Left Turn restriction at Moraga Way and Ivy Drive (north) is recommended to allow vehicles traveling to Orinda Intermediate School (OIS) to access Ivy Drive directly and reduce illegal turning behavior. To support improved corridor operations and reinforce Moraga Way as the preferred through route, evaluation of signal timing and coordination improvements along Moraga Way, including at Moraga Way and El Camino Moraga, is also recommended, with specific timing recommendations documented in the supplemental Intersection and Timing analysis report.

To address cut-through activity at other neighborhood access points, modifications to existing No Left Turn restriction times are recommended at Moraga Way and Southwaite Drive and at Moraga Way and Whitehall Drive. Adjusting these restrictions to operate from 7:30 a.m. to 8:30 a.m. better aligns with observed peak school arrival and cut-through activity and is intended to reduce conflicts and diversion to adjacent neighborhood streets.

In addition, evaluation of signal timing parameter adjustments and geometric improvements is recommended at Moraga Way and Coral Drive and at Moraga Way and Ivy Drive (south) to discourage cut-through movements and improve mainline operations and general intersection safety. Timingrelated recommendations for these locations are provided in the supplemental Intersection and Timing analysis report.

Finally, installation of a No Right Turn restriction at Ivy Drive and Ardith Drive from 7:30 a.m. to 8:30 a.m. is recommended to limit internal neighborhood circulation and deter cut-through movements between Ivy Drive and Ardith Drive during the morning peak period.

Together, these recommendations are intended to address documented cut-through patterns, improve safety and operational consistency, and balance school access needs with neighborhood protection.

Introduction
This technical memorandum summarizes the results and recommended solutions of two circulation studies on Moraga Way. The first study (i) reviews the applicability and effectiveness of three existing No Left Turn signs on Moraga Way. The second study (ii) examines the need of installing a new No Left Turn sign on Moraga Way at the Moraga Way & Orchard Road (north) intersection.

Study #1: Circulation Study near Ivy
Drive and Ardith Drive
There are 3 existing No Left Turn signs along
Moraga Way at the following intersections,
shown in Figure 1:
• Moraga Way & Ivy Drive (north)
• Moraga Way & Southwaite Court
• Moraga Way & Whitehall Drive
These signs were installed to deter vehicles
from taking Ivy Drive and Ardith Way to get to
the signalized Moraga Way & Ivy Drive (south)
and Moraga Way & Coral Drive intersections.

The city wants to study the effectiveness of
these signs since the three nearest schools (Del
Rey Elementary, Orinda Intermediate School,
and Miramonte High School) have changed
their start times since the installation of these
No Left Turn signs. Currently, the signs restrict
the left turns at these intersections from 7:00am
to 8:00am.

Figure 2 shows both of the roadway segments (Ivy
Drive and Ardith Drive) and the intersections that
currently have the No Left turn signs. Additionally, the City wants to determine the feasibility of installing a No Right Turn sign at the intersection of Ivy Drive &
Ardith Drive (shown in Figure 2) to deter cut-through
traffic from taking Ardith Drive to get to the
intersection of Moraga Way & Coral Drive.

The purpose of this study is to evaluate existing traffic patterns on Ivy Drive & Ardith Way and make
recommendations to deter cut-through traffic and
improve safety conditions on these roadways.

Existing Roadway Infrastructure & Traffic
Operations
Moraga Way is a bi-directional two-lane north-south
roadway with a posted speed limit of 35 miles per
hour (mph) throughout the study area. However,
specific speed limits are enforced between Coral
Drive and Ivy Drive (north) as stated on signage near
the segment, as shown in Figure 3. The speed limit
is reduced to 25 mph from Monday to Friday during
school hours (7:30-8:30 AM and 2:00-4:00 PM). The
roadway features a horizontal S-curve just north of
Coral Drive and connects several roadways,
including Ivy Drive, Eastwood/Estabueno Drive,
Coral Drive, Lavenida Drive, Whitehall Drive, and El
Camino Moraga. There are marked crosswalks
present at Ivy Drive (south), Eastwood Drive, Coral
Drive, and El Camino Moraga to facilitate pedestrian
movement across Moraga Way.

On-street parking is allowed along Moraga Way
between Altamount Drive and Leslee Lane. There
are Class II Bike Lanes throughout the entire
segment providing a dedicated space for cyclists.

Parking is restricted where bike lanes are present.

Parking is only allowed beyond the bike lanes or off
the roadway edge. This can be seen on Moraga Way between Ivy Drive (north) and El Camino Moraga.

Sidewalks are present on the southbound side of the street between Ivy Drive (south) and Altamount Figure 3: Special 25 mph speed limit sign on

Data Collection
AMG collected intersection turning movement counts (TMC) on Thursday, May 24, 2024, at six (6) locations during the weekday a.m. (7:30 a.m.-10:30 a.m.) peak period. The following are the seven intersections where data was collected, including the three intersections with the No Left Turn signs, as shown in Figure 4:

1. Moraga Way & Ivy Drive (north)

2. Moraga Way & Southwaite Court

3. Moraga Way & Whitehall Drive

4. Moraga Way & Coral Drive
(Signalized Intersection)

5. Moraga Way & Ivy Drive
(Signalized Intersection)

6. Ivy Drive & Ardith Drive
Speed Data was also collected on Ardith
Drive during the same weekday a.m. (7:30
a.m.-10:30 a.m.) peak period. It should be
noted that the data was collected during
these specific times to capture entrance and
dismissal times of nearby Miramonte High
School, Orinda Intermediate School, and
Del Rey Elementary School. Appendix A
contains the existing traffic counts.

The data collected was utilized to evaluate if
the times posted on the No Left Turn signs
at the intersections of Moraga Way & Ivy
Drive (north), Moraga Way & Southwaite
Court, and Moraga Way & Whitehall Drive
should be changed/modified.

Timing information was collected at the intersections of Moraga Way & Ivy Drive (south) and Moraga Way & Coral Drive to improve signal timing parameters and deter cut-through traffic.

Analysis
Field Observations & Visual Assessments
Field observations and visual assessments were conducted on Thursday, May 23, and Tuesday, May 28, 2024, during the weekday a.m. peak period. The purpose of this field review was to analyze any potential conflicts, safety issues, existing roadway conditions, and existing traffic to propose any potential improvements and recommendations.

Moraga Way & Ivy Drive (North) Intersection
At this intersection, there is currently a No Left Turn sign that restricts the left turn movement from Moraga Way onto Ivy Drive from 7:00am to 8:00am, as shown in Figure 5. It was observed that a few vehicles would make the illegal left turn/U-turn movement during the restricted time slot,
however, most of the traffic at the intersection seemed to occur from 8:00am to 9:00am. Figure 6 shows the queueing that is generated by the left turn/U-turn movement from 8:00am to 9:00am.

Moraga Way & Southwaite Court Intersection
At this intersection, there is currently a No Left Turn sign that restricts the left turn movement from Moraga Way
onto Southwaite Court from 7:00am to 8:00am. The sign at this intersection is identical to the sign shown in Figure 4.

No vehicles were observed making the illegal left turn/Uturn movement at the intersection.

Moraga Way & Whitehall Drive Intersection
At this intersection, there is currently a No Left Turn sign that restricts the left turn movement from Moraga Way
onto Whitehall Drive from 7:00am to 8:00am. The sign at this intersection is identical to the sign shown in Figure 4.

No vehicles were observed making the illegal left turn/Uturn movement at the intersection.

Ivy Drive & Ardith Drive Intersection
At this intersection, it was observed that many vehicles would make a right turn from Ivy Drive onto Ardith Drive from around 8:00am to 8:20am. Due to the nature of the roadway, there are sight visibility issues for drivers making that right turn movement from Ivy Drive onto Ardith Way.

Moraga Way & Ivy Drive (South) Intersection
Traffic congestion was observed at the intersection during the AM Peak. The movements with the longest queues were movements heading towards Miramonte High School, the eastbound right turn from Moraga Way onto Ivy Drive, the westbound left turn from Moraga Way onto Ivy Drive, and the southbound through movement on Ivy Drive. Figure 7 shows the queue that forms for the eastbound right turn movement.

Several pedestrians and school children were observed crossing all the crosswalks at the intersection. It was also observed that most pedestrians would cross the intersection at the unmarked crossing, across the north leg approach. While most pedestrians crossed the unmarked crossing during phases that did not conflict, there were several conflicts with vehicles making the eastbound right turn movement from Moraga Way onto Ivy Drive.

Cut-Through Analysis
AMG conducted a cut-through analysis on Ivy Drive
and Ardith Drive to see what percentage of trips on
these roadways were cut-through trips using
Streetlight Insight1
. Origin-Destination Analysis with
gates was used to calculate the percentage of trips
that were cut-through.

On Ivy Drive, the cut-through movement that was
analyzed was from vehicles getting on Ivy Drive
through the intersection of Moraga Way & Ivy Drive
(north) and ending up on Ivy Drive at the intersection
of Moraga Way & Ivy Drive (south) or ending up on
Coral Drive at the intersection of Moraga Way &
Coral Drive. Figure 8 shows the area used in the
origin-destination analysis. Table 1 shows the
percentage of cut-through trips on Ivy Drive during
the peak AM period. During the AM Peak hour (7:45am-8:45am) the average number of cut-through trips was 94 out of a total of 397 vehicles (24%) on Ivy Drive towards Coral Drive and the southern limit of Ivy Drive. It was also observed that while the percentage of cut-through trips is substantial during that AM Peak hour, the percentage of cut-through trips is reduced to 0% after 9:15am, showing that there is a definite peak of cut-through trips during the AM Peak hour.

No Left Turn Signs Analysis
Besides using Streetlight Insight data to determine cut-through movements on Ivy Drive and Ardith Drive, turning movement counts were also used to evaluate whether the No Left Turn signs on Ivy Drive, Southwaite Court, and Whitehall Drive should be removed or have a time change, and if new restricted movement signs should be installed on Ardith Drive. Figure 9 shows the number and percentage of vehicles making the southbound left turn from Moraga Way onto Ivy Drive compared to the rest of the movements at the intersection. The peak for the southbound left movement at the intersection occurs at 8:00am with 148 vehicles (53%) making this movement, and then dips significantly after 8:45am.

While the cut-through analysis and the turning movements at the intersection support a No Left turn sign at the intersection from 7:45am to 8:45am, this intersection is not only used by Miramonte High School students for cut-through, but it is also the main access point for Orinda Intermediate School (OIS). Consequently, most of the congestion for the southbound left movement, particularly from 8:30am to 8:45am is not only due to cut-through trips to the high school, but trips to OIS, since OIS starts school at 8:45am. Installing a No Left Turn sign at the intersection from 7:45am to 8:45 will likely prompt vehicles going to OIS to alternate routes that will increase cut-through trips on the neighboring roadways and worsen congestion on Moraga Way. Therefore, it is recommended that the No Left turn sign at the intersection of Moraga Way & Ivy Drive be removed.

Figure 10 shows the number and
percentage of vehicles making the
eastbound right turn from Ivy Drive
to Ardith Drive compared to the
rest of the movements at the
intersection. The peak for the
eastbound right movement at the
intersection occurs at 8:00am with
44 vehicles (29%) making this
movement, and gradually
decreases after. These turning
movements support installing a No
Right Turn sign on Ivy Drive onto
Ardith Way from 7:30am to
8:30am. This right turn restriction
will deter vehicles from using
Ardith Drive as a cut-through route
while also accommodating vehicles trying to go to OIS.

Figure 11 shows the percentage of
vehicles making the southbound left
turn from Moraga Way onto
Whitehall Drive compared to the rest
of the movements at the
intersection. The peak for the
southbound left movement at the
intersection occurs at 8:30am with 8
vehicles (7%) making this
movement. At the intersection of
Moraga Way & Southwaite Court,
very few vehicles are making the
southbound left turn movement
during the AM peak period. The
highest occurrence (2 vehicles) for
the southbound left movement at
this intersection occurs at 8:15am.

While the No Left Turn is recommended to be removed at the intersection of Moraga Way & Ivy Drive, it is recommended to maintain the No Left Turn signs at the intersections of Moraga Way & Southwaite Court and Moraga Way & Whitehall Drive and change the timing restriction on the signs from 7:00am to 8:00am to 7:30am to 8:30am.

Although very few vehicles are making the left turn at both intersections, removing the signs will likely prompt vehicles into making the left turn movement onto Southwaite Court and Whitehall Drive.

Removing the signs would potentially increase the number of conflicts occurring on Southwaite Court since it is a dead end and increase the cut-through traffic on Whitehall Drive since it connects to Ardith Drive and Coral Drive to the north.

Speed Analysis
AMG utilized the speed data collected on Ardith Drive to determine if any traffic calming or speed limit changes were necessary on those roadways. The speed data was collected adjacent to 4 Westover Court.

The posted speed limit on Ardith Drive is 25 miles per hour (mph). Going more than 5+ miles per hour over the speed limit is considered speeding, so any vehicles going more than 30 miles per hour on Ardith Drive are speeding. Table 2 shows the results of the speed analysis. The number and percentage of vehicles going over 30 miles per hour and over during the entire day was 10 out of 309 vehicles (3%) in the southbound direction and 10 out of 221 vehicles (5%) in the northbound direction, respectively.

During the AM Peak period, the number and percentage of vehicles going over 30 miles per hour was 6 out of 109 vehicles (6%) in the southbound direction and 1 out of 53 vehicles (2%) in the northbound direction, respectively. Since the percentage of vehicles going over 30 miles per hour does not vary significantly between the AM Peak period and the daily period, no traffic calming improvements or speed limit changes are recommended on Ardith Drive at this time.

To verify results of this speed analysis, the Orinda Police Department set up a speed trailer on Ardith Drive to get additional speed data. The speed data was collected from Monday, November 25th, 2024, to Sunday, December 8th, 2024, near the Ardith Drive & Westover Court intersection, for vehicles driving in the southbound direction. Table 3 shows the results of the speed analysis using this data.

From the speed data collected, the number and percentage of vehicles going over 30 miles per hour and over during the thirteen-day period at all hours (24-hour period) was 254 out of 4,873 vehicles (5%) in the southbound direction. The number and percentage of vehicles going over 30 miles per hour and over during the thirteen-day period during the a.m. peak period (7:00am to 9:00am) was 117 out of 3,647 vehicles (12%) in the southbound direction.

Based on the results, the daily percentage of southbound trips going over 30 miles per hour is similar, confirming the previous analysis. However, the new data suggests that during the AM Peak Period, the percentage of southbound trips going over 30 miles per hour is substantially higher than the previous analysis proposes. Due to the high percentage of speeding in the southbound direction, the City could consider installing a No Right Turn sign at the intersection of Ivy Drive & Ardith Drive. The City could also consider some traffic calming improvements, including additional speed limit signage throughout the entire roadway section.

Additionally, the City could change the prima facie speed limit on Ardith Drive from 25 mph to 15 mph.

Ardith Drive meets the requirements to change the prima facie speed limit per California Vehicle Code 22358.4, and it would require the City to conduct an Engineering & Traffic Study and then pass an ordinance/resolution. After the ordinance/resolution is passed, the City would be required to install advanced speed limit warning signs.

Moraga Way & Ivy Drive (south) and Moraga Way & Coral Drive Timing Evaluation AMG utilized the existing timing sheet and field evaluation to prepare the existing Synchro for the intersections of Moraga Way & Ivy Drive (south) and Moraga Way & Coral Drive. Currently, the timing parameters favor the movements through Moraga Way, but the delays on the westbound approaches of Ivy Drive and Coral Drive are currently Level of Service (LOS) E & C, respectively. Therefore, AMG proposes changes to the max limits for the phases that control those approaches to change the delays on those approaches to LOS F at the Moraga Way & Ivy Drive (south) and to LOS E at Moraga Way & Coral Drive intersection. At Moraga Way & Coral Drive, the minimum green time and the Flash Don’t Walk parameter were also modified based on the crosswalk length and the updated MUTCD recommendations. This change will deter drivers from using Ivy Drive and Coral Drive as cut-through roadways, since there will be more delays. AMG will go to the field and implement these changes on the controller. Minimum gap times were also reviewed but no changes to existing minimum gap times are recommended. Appendix B shows the proposed changes on the intersection timing sheets.

Moraga Way & Ivy Drive (south) Intersection Evaluation
As mentioned in the field review, and supported by the pedestrian counts at the intersection, a large number of students and pedestrians use the unmarked crossing across the north approach on Moraga Way. The City could consider installing crosswalk markings at that approach to improve pedestrian safety and improve driver awareness. However, this could lead to further delays and congestion at the intersection due to more pedestrians feeling safe to use this crossing.

It was also observed that there is a long queue for the eastbound right turn movement at the intersection. Due to the long queue for that movement, drivers are inpatient and try to make that movement as soon as they can. However, due to the large numbers of pedestrians using the west crosswalk while it is also green for that movement, there was a potential conflict for pedestrians getting hit by impatient drivers. A Leading Pedestrian Interval (LPI) could be implemented in the future at that crossing to help mitigate that conflict.

Conclusion
Based on the results of the analysis, the existing No Left Turn sign at the intersection of Moraga Way & Ivy Drive (north) should be removed, while the existing No Left Turn sign at the intersections of Southwaite Court and Whitehall Drive should have timing changes. A No Right Turn sign should be installed at the intersection of Ivy Drive & Ardith Drive and timing changes should be applied to the intersections of Moraga Way & Ivy Drive (south) and Moraga Way & Coral Drive to deter cut-through trips. All these proposed changes should be implemented as part of a “pilot” program. A few months after implementing these changes, AMG will review their effectiveness through data collection and field review. If cut-through trips have not decreased, the No Left Turn sign at the intersection of Moraga Way & Ivy Drive (north) should be reinstalled with timing changes. Table 4 below summarizes the priority, locations, and recommended actions to reduce cut-through trips and improve safety throughout the entire study segment.

Study #2: Circulation Study near Orchard Rd
The purpose of this study is to evaluate existing
traffic patterns on Orchard Road and make
recommendations to deter cut-through traffic and
improve safety conditions on this roadway.

The feasibility of installing a No Left Turn sign at
the intersection of Moraga Way & Orchard Road
(north) to deter cut-through traffic from taking
Orchard Road to get to the intersection of Orchard
Road & Glorietta Boulevard was analyzed. Figure
12 shows the study roadway segment (Orchard
Road) and the intersection of Moraga Way &
Orchard Road (north) where the No Left turn sign is
considered.

Existing Roadway Infrastructure & Traffic
Operations
Orchard Road is a bi-directional, two-lane northsouth roadway with a posted speed limit of 25 miles per hour (mph), which reduces to 15 mph around
areas with significant horizontal and vertical
curvatures, as shown in Figure 13. The road features
numerous horizontal curves that influence the speed
limit, ensuring safer travel through the winding
segments. Orchard Road connects Moraga Way to
Oakwood Road, Brookside Road, Scenic Drive,
Valley Drive, and Glorietta Boulevard. There are no
marked crosswalks, sidewalks, or pedestrian safety
signs along Orchard Road. Although there are no
posted signs regarding on-street parking, vehicles
are observed to park in areas with enough space to
avoid disrupting road traffic. The street does not
include any dedicated bike facilities.

Data Collection
AMG collected intersection turning movement
counts (TMC) on Thursday, May 24, 2024, at the
study intersection, Moraga Way & Orchard Road
(north) during the weekday a.m. (7:30 a.m.-10:30 a.m.) peak period. Speed Data was also collected on Figure 12: Study Roadway Segments & location

Orchard Road during the same weekday a.m. (7:30 a.m.-10:30 a.m.) peak period. It should be noted that the data was collected during these specific times to capture entrance and dismissal times of nearby Glorietta Elementary School, Miramonte High School, Orinda Intermediate School, and Del Rey Elementary School. Additional speed data was collected from Tuesday, October 8th, 2024 to Sunday, October 13th, 2024 to verify speed results. Appendix C contains the existing traffic counts for this study.

The data collected was utilized to evaluate the need for installing a No Left Turn sign at the intersection of Moraga Way & Orchard Road and additional traffic calming measures on Orchard Road.

Analysis
Field Observations & Visual Assessments
Field observations and visual assessments were conducted on Tuesday, May 28, 2024, during the weekday a.m. peak period. The purpose of this field review was to analyze any potential conflicts, safety issues, existing roadway conditions, and existing traffic to propose any potential improvements and recommendations.

Moraga Way & Orchard Rd (North) Intersection
Not many vehicles were observed making a left turn movement from Moraga Way onto Orchard Rd at this intersection during the am peak period. However, for the few vehicles making that left turn, it was observed that it took vehicles a long time to find a gap in traffic that allowed them to safely complete the left turn maneuver.

Cut-Through Analysis
AMG conducted a cut-through analysis on Orchard
Road to see what percentage of trips on these
roadways were cut-through trips using Streetlight
Insight2
. Origin-Destination Analysis with gates was
used to calculate the percentage of trips that were cutthrough.

On Orchard Road, the cut-through movement that
was analyzed was from vehicles getting on Orchard
Road through the intersection of Moraga Way &
Orchard Road (north) and ending up on Orchard Road
at the intersection of Glorietta Blvd & Orchard Road.

Figure 14 shows the area used in the origin-destination analysis. Table 5 shows the percentage of cut-through
trips on Orchard Road during the peak AM period.

During the AM Peak hour (7:45am-8:45am) the

average number of cut-through trips was 9 out of a total of 47 vehicles (20%) on Orchard Road. It was also observed that while the percentage of cut-through trips is substantial during that AM Peak hour, the percentage of cut-through trips is reduced to 0% after 8:45am, showing that there is a definite peak of cut-through trips during the AM Peak hour.

No Left Turn Signs Analysis
Besides using Streetlight Insight
data to determine cut-through
movements on Orchard Road,
turning movement counts were
also used to evaluate whether new
restricted No Left Turn movement
signs should be installed on
Orchard Road. Figure 15 shows
the percentage of vehicles making
the southbound left turn from
Moraga Way onto Orchard Road
compared to the rest of the
movements at the intersection.

The peak for the southbound left
movement at the intersection
occurs at 8:00am with 9 vehicles (4%) making this movement, and gradually decreases after. Based on the cut-through analysis and the turning movements at the intersection, the installation of a No Left Turn sign is not supported currently.

Speed Analysis
AMG utilized the speed data collected on Orchard Road to determine if any traffic calming or speed limit changes were necessary on those roadways. The speed data was collected in front of 50/53 Orchard Road and 68/70 Orchard Road.

The posted speed limit on Orchard Road is 25 miles per hour (mph), however there are multiple warning signs for 15 miles per hour (mph) wherever there is horizontal curvature. Going more than 5+ miles per hour over the speed limit is considered speeding, so any vehicles going more than 30 miles per hour on the straight sections of Orchard Road are speeding. Table 6 & Table 7 show the results of the speed analysis. From the speed data collected in front of 50/53 Orchard Road, the number and percentage of vehicles going over 30 miles per hour and over during the entire day was 22 out of 156 vehicles (14%) in the southbound direction and 23 out of 262 vehicles (9%) in the northbound direction, respectively.

During the AM Peak period, the number and percentage of vehicles going over 30 miles per hour was 5 out of 35 vehicles (14%) in the southbound direction and 2 out of 59 vehicles (3%) in the northbound direction, respectively. From the speed data collected in front of 68/70 Orchard Road, the number and percentage of vehicles going over 30 miles per hour and over during the entire day was 59 out of 483 vehicles (12%) in the southbound direction and 39 out of 426 vehicles (9%) in the northbound direction, respectively. During the AM Peak period, the number and percentage of vehicles going over 30 miles per hour was 15 out of 97 vehicles (15%) in the southbound direction and 7 out of 97 vehicles (7%) in the northbound direction, respectively. The percentages of vehicles going over 30 miles per hour do not significantly increase during the AM Peak period at both locations.

To verify results of this speed analysis, the Orinda Police Department set up a speed trailer on Orchard Road to get additional speed data. The speed data was collected from Tuesday, October 8th, 2024, to Sunday, October 13th, 2024, just north of the Orchard Road & Brookside Drive intersection, for vehicles driving in the northbound direction. Table 8 shows the results of the speed analysis using this data.

From the speed data collected, the number and percentage of vehicles going over 30 miles per hour and over during the six-day period at all hours (24-hour period) was 598 out of 15,049 vehicles (4%) in the northbound direction. The number and percentage of vehicles going over 30 miles per hour and over Item C.1

during the six-day period during the a.m. peak period (7:00am to 9:00am) was 195 out of 3,647 vehicles (5%) in the northbound direction.

Since the percentages obtained with the additional speed data are similar to the previous speed analysis, the new data confirms that the percentages of vehicles going over 30 miles per hour do not significantly increase during the AM Peak period at both locations.

Conclusion
Based on the results of the analysis, installing a new No Left turn sign at the intersection of Moraga Way & Orchard Road (north) is not feasible at the moment. Based on the speed analysis, the percentages of vehicles going over 30 miles per hour do not significantly increase during the AM Peak period at both locations. However, due to the high percentage of speeding in the southbound direction throughout the day, the City could consider some traffic calming improvements, including additional speed limit signage throughout the entire roadway section, and speed cushions at selected locations.

Per the City’s Neighborhood Traffic Management Program (NTMP), speed cushions on Orchard Road may be feasible since it is a residential road and has low average daily traffic.

Additionally, the City could change the prima facie speed limit on Orchard Road from 25 mph to 15 mph. Orchard Road meets the requirements to change the prima facie speed limit per California Vehicle Code 22358.4, and it would require the City to conduct an Engineering & Traffic Study and then pass an ordinance/resolution. After the ordinance/resolution is passed, the City would be required to install advanced speed limit warning signs.

Subject: Evaluate Potential Parking Restrictions at Del Rey Elementary in the City of Orinda, CA
It is our understanding that along El Camino Moraga adjacent to Del Rey Elementary, cars are parked or waiting along red curb area on the east side and block sight visibility for vehicles exiting the parking lot.

Apparently, vehicles also park on the sidewalk
in the yellow area as shown in Figure 1. There is
currently no parking on the west side of the
street.

AMG conducted a field review to determine if
more parking restrictions are needed or
recommend any changes to the existing.

Observations During Field Visit
AMG conducted field observations on March 20,
2025, during these hours:

Pick-up observations – 7:45 – 8:00 AM
Drop-off observations – 2:40 – 3:00 PM
AMG staff was present 30 minutes before and
after each event.

The following are observations of key issues
during the filed visit.

1. Parking-Related Issues:
• Unpermitted Parking: Vehicles parked between the school’s entry and exit driveways on El Camino Moraga and obstruct the continuous sidewalk, forcing pedestrians onto the street as shown in Figure 2.
• Encroachment on Narrow Sidewalk: Vehicles parked along the eastbound sidewalk near the exit driveway and reduce pedestrian space and create conflicts with opening car doors.
• Parking at Exit Driveway: Vehicles parked on the east side of the school’s exit driveway during PM pick-up which blocks sightlines and reduces visibility of oncoming traffic. • Parking Along Red Curb: Unpermitted parking along the red curb opposite Don Gabriel Way during AM drop-off reduces visibility and obstructs pedestrian flow.

May 14, 2025

2. Visibility and Sightline Issues:
• Crosswalk Visibility: On-street parking on both the east and west sides of the Don Gabriel Way crosswalk obstruct sightlines, making it difficult for drivers to see pedestrians crossing.
• Student Safety Concern: Parked
vehicles near the Don Gabriel Way
crosswalk create visibility concern
for students, as observed by the
crossing guard.
• U-Turn Conflicts: Vehicles making
U-turns on El Camino Moraga
disrupt circulation and create
additional visibility issues for both
pedestrians and drivers.

3. Circulation and Traffic Flow Issues:
• Discontinuous Sidewalks: Missing
sidewalk sections along the
eastbound direction of El Camino
Moraga force pedestrians to use
the street, creating a challenging
walking environment.
• Pedestrian Congestion: The narrow
6-foot sidewalk on the eastbound
side of El Camino Moraga serves as
the primary pedestrian route but is
obstructed by parked vehicles,
reducing available walking space. The opening of car doors onto the sidewalk further exacerbates the issue, creating a safety concern for pedestrians. • No Separate Bus Zone: The lack of a designated bus loading area leads to conflicts between school buses and private vehicles during peak times. • Intersection Congestion: Three-point turns and U-turns made by vehicles on El Camino Moraga contribute to traffic congestion and safety
concerns.

Additional detailed field notes and photos taken during the field visit are contained in Appendix A.

Recommendation
To provide a safer environment for pedestrians and improve intersection sight visibility, AMG recommend the following:
• Install “No Parking” or red curb on curb (southside)
between entry and exit driveways.
• Install “No Parking” or red curb on curb (southside) 150’ east of the exit driveway as shown in Figure 3.

DEL REY ELEMENTARY SCHOOL, ORINDA

FIELD VISIT MEMO
Date – March 20, 2025
Time
Pick-up observations – 7:45 – 8:00 AM
Drop-off observations – 2:40 – 3:000 PM

INTRODUCTION
This memo summarizes the findings from a field visit conducted at Del Rey Elementary School, located on El Camino Moraga, in the City of Orinda.

SUMMARY
The first drop-off occurred at 7:28 AM, with all activity cleared by 8:10 AM.

PEDESTRIAN SAFETY INFRASTRUCTURE

1. Crosswalks:
o Markings: High-visibility yellow ladder crosswalks are present on El Camino Moraga at the following intersections:
 Don Gabriel Way (North leg).
 Moraga Way (West & South legs).
o Condition: Crosswalk markings appear freshly painted and are in good condition. o Placement: Crosswalks are logically placed at intersections. However, due to high residential density to the north of the school, approximately 5 - 10 pedestrians were observed jaywalking, particularly at Don Gabriel Way and the school’s exit driveway.

2. Crossing Aids:
o No pedestrian crossing signals, or countdown timers are present as the intersections are unsignalized.
o A crossing guard was present at the El Camino Moraga and Don Gabriel Way intersection (7:45 - 8:10 AM and 2:40 – 3:00 PM), effectively managing pedestrian flow.

3. Sidewalks:
o Sidewalks along the eastbound direction of El Camino Moraga are discontinuous and missing in some sections. A short sidewalk exists between Don Gabriel Way and the school’s exit driveway along the westbound direction, but the remaining pedestrian traffic must rely on a 6-foot sidewalk along the eastbound direction. However, this sidewalk is frequently obstructed by unpermitted parking between the school’s entry and exit driveways, impacting pedestrian flow and safety.

Additional unpermitted parking between the exit driveway and Moraga Way further worsens Item C.1
Packet Page 151
DEL REY ELEMENTARY SCHOOL, ORINDA – FIELD VISIT MEMO
2 conditions, with vehicle doors opening onto the already narrow sidewalk which serves at the primary pedestrian access.
o On the west side of Don Gabriel Way, between the parking lot and the crosswalk, a barricaded 6-foot sidewalk serves as a safety buffer from unpermitted parking along the red curb during the AM dropoff. However, these parked vehicles create visibility concerns for students crossing at the Don Gabriel Way crosswalk, as observed during the field visit and noted by the crossing guard.

4. Curb Ramps:
o Curb ramps are present, ADA-compliant, and aligned with crosswalks.

5. Pedestrian Barriers:
o The lack of continuous sidewalks and parking encroaching on the only sidewalk along the eastbound direction creates an unsafe pedestrian environment, forcing children to walk in the street instead of on the sidewalk.
o Illegal on-street parking (AM-Drop-off) on the west side of Don Gabriel Way and near the school's exit driveway obstructs visibility, further compromising pedestrian safety.

VEHICLE SAFETY INFRASTRUCTURE

1. School Zone Signage:
o School zone signs are located at key points but lack flashing beacons due to the absence of signalized intersections.

2. Speed Control Measures:
o No speed humps or speed reduction measures are present.

3. Drop-Off/Pick-Up Zone Design:
o Clearly marked with "No Parking" and "Drop-Off Only" signage. o No separate zones for buses and private vehicles, leading to occasional conflicts.

CYCLIST SAFETY INFRASTRUCTURE

1. Bike Lanes:
o No bike lanes or sharrows are present. During the field visit, there were very few bikers observed.

SIGHTLINES AND VISIBILITY
• Unpermitted on-street parking on both the east and west sides of the crosswalk on Don Gabriel Way during AM drop-off and PM pick-up obstructs visibility and sightlines. • During PM pick-up, parking on the east side of the exit driveway blocks sightlines and reduces visibility of oncoming traffic.

TRAFFIC MANAGEMENT FEATURES

1. Signage and Pavement Markings:
o Markings for loading/unloading zones and fire lanes are present. o "No U-turns" signs are needed as vehicles were observed making three-point turns on El Camino Moraga, adding to congestion and safety concerns.

2. Intersection Design:
o All intersections are stop-controlled with stop signs..

Item C.1
Packet Page 152
DEL REY ELEMENTARY SCHOOL, ORINDA – FIELD VISIT MEMO
3 CROSSING GUARD EFFECTIVENESS
o Managed pedestrian flow optimally by grouping 5-6 students before allowing crossings, minimizing vehicle delays.

STAFF VOLUNTEER PRESENCE
o One staff member assisted with vehicle unloading.

SPECIFIC ISSUES:

1. Parking-Related Issues:
• Unpermitted Parking: Vehicles parked between the school’s entry and exit driveways on El Camino Moraga obstruct the only continuous sidewalk, forcing pedestrians into the street. • Encroachment on Narrow Sidewalk: Vehicles parked along the eastbound sidewalk near the exit driveway reduce pedestrian space and create conflicts with opening car doors. • Parking at Exit Driveway: Vehicles parked on the east side of the school’s exit driveway during PM pickup block sightlines and reduce visibility of oncoming traffic. • Parking Along Red Curb: Unpermitted parking along the red curb on Don Gabriel Way during AM dropoff reduces visibility and obstructs pedestrian flow.

2. Visibility and Sightline Issues:
• Crosswalk Visibility: On-street parking on both the east and west sides of the Don Gabriel Way crosswalk obstruct sightlines, making it difficult for drivers to see pedestrians cross. • Student Safety Concern: Parked vehicles near the Don Gabriel Way crosswalk create visibility concern for students, as observed by the crossing guard.
• U-Turn Conflicts: Vehicles making U-turns on El Camino Moraga disrupt circulation and create additional visibility hazards for both pedestrians and drivers.

3. Circulation and Traffic Flow Issues:
• Discontinuous Sidewalks: Missing sidewalk sections along the eastbound direction of El Camino Moraga force pedestrians to use the street, creating a hazardous walking environment. • Pedestrian Congestion: The narrow 6-foot sidewalk on the eastbound side of El Camino Moraga serves as the primary pedestrian route but is obstructed by parked vehicles, reducing safe walking space. • No Separate Bus Zone: The lack of a designated bus loading area leads to conflicts between school buses and private vehicles during peak times.
• Intersection Congestion: Three-point turns and U-turns made by vehicles on El Camino Moraga contribute to traffic congestion and pedestrian safety risks.

AGENDA TITLE: Remove Existing “No Left Turn” Sign from southbound Moraga Way at Ivy Drive (North) Intersection and Install a New “No Right Turn” Sign at southbound Ivy Drive and Ardith Drive Intersection
RECOMMENDATION:

Approve Resolution 41-25 (Traffic Order 238) to authorize the following:
1) Remove existing “No Left Turn” signs at southbound Moraga Way/Ivy Drive (north) intersection and Rescind Resolution 15-02 (Traffic Order 115); 2) Change existing time restriction on “No U-Turn/No Left Turn” signs on southbound Moraga Way at Southwaite Court on school days to 7:30 a.m. to 8:30.a.m., Weekdays Only and Rescind Resolution 41-12 (Traffic Order 155);
3) Change existing time restriction on “No U-Turn/No Left Turn” signs on southbound Moraga Way at Whitehall Drive on school days to 7:30 a.m. to 8:30.a.m., weekdays only and Rescind Resolution 42-12 (Traffic Order 156); and
4) Install new “No Right Turn” sign at southbound Ivy Drive at Ardith Drive restricting turn movements on school days from 7:30 a.m. to 8:30.a.m., weekdays only.

BACKGROUND:

In 1999, the City conducted a study to review the traffic concerns in the Ivy Drive neighborhood. There are three grade schools in the vicinity of the Ivy Drive neighborhood with multiple school start times. Del Rey Elementary School started at 8:00 a.m., Orinda Intermediate School (OIS) started at 8:45 a.m., and Miramonte High School started at 8:00 a.m. in 1999. Based on results of the study and feedback from residents, traffic issues were caused by three major factors at that time:

1. Speeding by neighborhood residents.

2. Drop off and pickup traffic at Orinda Intermediate School.

3. Traffic to Miramonte High School utilizing Ivy Drive to bypass congestion on Moraga Way.

At the direction of the City Council, several measures were implemented. These included restriping Ivy Drive and installing stop signs at three intersections: Ardith Drive and Coral Drive, Eastwood Drive and Coral Drive, and Ardith Drive and Ivy Drive. The traffic study did not recommend measures such as no left turn restrictions that would reduce volumes on Ivy Drive because it would increase volumes on adjacent streets such as Coral Drive.

At the June 20, 2000, City Council meeting, Ivy Drive neighborhood traffic calming measures were further discussed. Various traffic calming recommendations were presented to City Council including installation of a “No Left Turn” Sign from southbound Moraga Way at Ivy Drive (North) 7:00 a.m. to 8:00 a.m. Monday through Friday during F.9
Packet Pg. 98
Item C.1
Packet Page 164
the school year for a trial period. During the trial period, Staff would evaluate compliance with the prohibition and what effect it has had on traffic patterns in the area.

The City Council adopted Resolution 55-00 (Traffic Order 86) on August 1, 2000, for a three-month trial period that prohibited left turns from Moraga Way onto Ivy Drive between the hours of 7:00 a.m. and 8:00 a.m. Monday through Friday beginning August 28, 2000.

Staff evaluated the traffic patterns and found the new “No Left Turn” signs had the desired effect, and therefore they were approved for permanent installation at the April 2, 2002, City Council meeting by Resolution 15-02 (Traffic Order 115). Traffic Order 115 states, “Left Turns from Moraga Way onto Ivy Drive shall be prohibited on school days between the hours of 7:00 a.m. and 8:00 a.m., Monday through Friday beginning April 3, 2002. This shall rescind the Traffic Order No. 86, passed by Resolution 55-00 on August 1, 2000.” The existing “No Left Turn” signs still reflect these hours and are removed every summer and reinstalled when school is back in session.

In August of 2012, the City Council adopted Resolution 41-12, Traffic Order 155, prohibiting U-turns and left turns from Moraga Way onto Southwaite Court on school days between the hours of 7 a.m. and 8 a.m., Monday through Friday. At the same meeting, the City Council also adopted Resolution 42-12, Traffic Order 156, prohibiting U-turns and left turns from Moraga Way onto Whitehall Drive on school days between the hours of 7 a.m. and 8 a.m., Monday through Friday.

In January 2017, per request from then Chair Roberts, the Traffic Safety Advisory Committee (TSAC) considered adjusting the hours for the restricted “No Left Turn” from Moraga Way onto Ivy Drive (north) due to a change in the Miramonte High School start times on Monday, Wednesday, and Friday from 8:00 a.m. to 8:30 a.m. The TSAC discussed adjusting the time to later than 8:00 a.m. but realized that it would negatively impact those traveling to OIS which starts at 8:45 a.m. and will not align well with the days when school started earlier. Members of the Orinda Union School District (OUSD) and the OIS Principal also expressed concerns that extending the turn restriction time would negatively affect vehicles traveling to OIS. Following discussion and feedback from neighbors and school district, TSAC did not take any action to modify the timings on the sign.

The location map in Attachment B shows the existing intersections with turn restriction signs and evaluated intersections.

DISCUSSION:

California's SB 328, approved in 2019, required high schools to start no earlier than 8:30 a.m. and middle schools no earlier than 8:00 a.m. to be implemented no later than July 1, 2022. Miramonte High School start time was changed on all days to 8:30 a.m. starting the 2022-2023 school year.

In January 2023, the TSAC was requested by OIS staff to re-evaluate the need for the “No Left Turn” signs from Moraga Way onto Ivy Drive (north) because the prohibited left F.9
Packet Pg. 99
Item C.1
Packet Page 165
was no longer serving its intended purpose after Miramonte High School changed the start time from 8:00 a.m. to 8:30 a.m. for all days, and it adversely affected staff and students who have earlier classes at OIS before 8:00 a.m., which required them to take alternate routes to school. The current start time for OIS is 8:45 a.m.

The existing restriction from southbound Moraga Way turning movement onto Ivy Drive requires southbound vehicles to use Coral Drive (a signalized intersection) as an alternate route to access Ivy Drive, including traffic going to OIS. Vehicles taking a left from southbound Moraga Way onto Coral Drive, must wait for a break in traffic without the benefit of a dedicated left-turn arrow or a separate left-turn signal.

A Public Meeting was held on October 25, 2023, via Zoom, to discuss potential changes to the existing “No Left Turn” signs at the Moraga Way and Ivy Drive (north), Moraga Way and Southwaite Court, and Moraga Way and Whitehall Drive intersections. Further outreach included mailing approximately 675 mailers to the property owners of the Ivy Drive neighborhood, as well as notifying students, teachers and administration of Miramonte High School and Orinda Intermediate School. The Zoom meeting was attended by approximately 90 people. Staff also received numerous emails before and after the meeting, both in support of keeping the signs and removing them. Most comments and concerns regarded the “No Left Turn” signs, volume of vehicles, and speeding in the neighborhood.

Staff presented the findings to the TSAC at the May 13, 2024 meeting and recommended funding a traffic study to review the nature and composition of traffic utilizing Ivy Drive from the Moraga Way and Ivy Drive (north) intersection to the Moraga Way and Ivy Drive (south) intersection. In May of 2024, the City issued a task order to Advanced Mobility Group (AMG), who is an on-call traffic engineering firm under contract with the City to conduct the study during the 2024-2025 school year, to evaluate existing traffic patterns on Ivy Drive and Ardith Drive and provide recommendations to deter cut-through traffic and improve safety conditions in the Ivy Drive neighborhood. The Moraga Way Circulation Study was completed in December 2024 (Attachment C).

The study evaluated if the times posted on the “No Left Turn” and “No U-Turn/No Left Turn” signs at the intersections of Moraga Way and Ivy Drive (north), Moraga Way and Southwaite Court, and Moraga Way and Whitehall Drive should remain, be modified, or the signs removed. Additional conditions that would improve traffic circulation in the neighborhood were also evaluated.

The Traffic Study Recommendations Include:
1) Remove the “No Left Turn” sign at southbound Moraga Way and Ivy Drive (north) intersection;
2) Change existing time restriction on “No U-Turn/No Left Turn” signs on southbound Moraga Way at Southwaite Court and on southbound Moraga Way at Whitehall Drive, to 7:30 a.m. to 8:30.a.m.;
3) Install new “No Right Turn” sign on southbound Ivy Drive at Ardith Drive, restricting right turn movements from 7:30 a.m. to 8:30.a.m.; and
F.9
Packet Pg. 100
Item C.1
Packet Page 166
4) Modify traffic signal “Maximum Limit” parameters at Moraga Way and Coral Drive and Moraga Way and Ivy Drive (south) intersections to improve circulation on Moraga Way.

The traffic study noted that very few vehicles make the left turn at southbound Moraga Way at Southwaite Court and on southbound Moraga Way at Whitehall Drive but stated that “removing the signs will likely prompt vehicles into making the left turn movement onto Southwaite Court and Whitehall Drive. Removing the signs would potentially increase the number of conflicts occurring on Southwaite Court since it is a dead end and increase the cut-through traffic on Whitehall Drive since it connects to Ardith Drive and Coral Drive to the north.”
The traffic study recommends the changes to be implemented on a trial basis to monitor performance and take corrective actions if required.

Staff presented the study and recommendations to the TSAC on February 24, 2025.

Staff recommended that TSAC recommend to the City Council approval to implement the changes. The TSAC meeting was well attended by Ivy Drive neighborhood residents, and teachers and students of OIS. After reviewing the study and hearing public comments, the TSAC requested Staff to perform additional public outreach in the form of a second public meeting via Zoom to present a “Yes/No” survey requesting additional feedback about the prohibited turn movement signs and other recommendations presented in the study.

The second public meeting was held on April 16, 2025 via Zoom. Outreach included mailing approximately 675 mailers to the property owners of the Ivy Drive neighborhood, as well as students, teachers and administration of Miramonte High School and OIS.

The Zoom meeting was attended by 41 people and an additional six survey responses were received from people that had technical difficulties during the meeting. Staff also received numerous emails regarding the “No Left Turn” signs, the proposed “No Right Turn” sign from Ivy Drive to Ardith, volume of vehicles, and speeding in the neighborhood.

Nine survey questions were presented during the meeting as polls. The second public meeting survey results were then presented to the TSAC at the May 19, 2025, meeting.

Responses received from the survey were somewhat distributed, but the overall preference was in support of removing or modifying the existing turning restriction time and support for removal of the “No Left Turn” signs on Moraga Way at Ivy Drive (north) as part of a pilot program for five to six months in the 25/26 school year as supported by the traffic study. The TSAC recommended City Council approval of the proposed changes.

Consistent with the direction of TSAC, Staff is recommending that the City Council approve Resolution 41-25, Traffic Order 238, which will:
1) Remove the existing “No Left Turn” signs at southbound Moraga Way/Ivy Drive (north) intersection and Rescind Resolution 15-02 (Traffic Order 115); F.9
Packet Pg. 101
Item C.1
Packet Page 167
2) Change existing time restriction on “No U-Turn/No Left Turn” signs on southbound Moraga Way at Southwaite Court on school days to 7:30 a.m. to 8:30.a.m., Weekdays Only and Rescind Resolution 41-12 (Traffic Order 155); 3) Change existing time restriction on “No U-Turn/No Left Turn” signs on southbound Moraga Way at Whitehall Drive on school days to 7:30 a.m. to 8:30.a.m., weekdays only and Rescind Resolution 42-12 (Traffic Order 156); and 4) Install new “No Right Turn” sign at southbound Ivy Drive at Ardith Drive restricting turn movements on school days from 7:30 a.m. to 8:30.a.m., weekdays only.

NEXT STEPS:

Upon City Council approval, Staff will implement the changes prior to start of the 2025/2026 school year. The changes will be monitored during the first year and Staff will bring back recommendations to the City Council if further changes are necessary.

FISCAL IMPACT:

The cost for implementing the proposed changes and reevaluation in the first year is estimated to be about $7,000 plus Staff time for procurement and managing the project, plus ongoing maintenance expenditure of installation and removal of the restricted turn movement signs at the beginning and end of each school year. There are sufficient funds available under Traffic Calming and Pedestrian Safety Program (CIP # 4107) budget, which is funded by Fund #200, Gas Tax.

Public Works Director Scott Christie gave a brief staff report and PowerPoint presentation of the matter.

Vice Mayor Iverson inquired whether residents on Ardith Drive had provided input regarding the proposed right-turn recommendation. Mr. Christie indicated that a few comments had been received.

Councilmember Hoxie raised concerns about the traffic study's validity, noting it was conducted on a school finals day (Friday, May 24), which may have resulted in atypically low traffic. She also observed that the limited number of left turns recorded between 7:00–8:00 a.m. could be attributed to an existing “No Left Turn” sign.

Councilmember Gee emphasized the complexity of the traffic issue, likening it to a situation where addressing a problem in one area causes new problems elsewhere.

She sought clarity on the core problem being addressed—whether it was related to changes in Miramonte’s schedule or access to OIS—and acknowledged the broader challenges of managing peak-time traffic in neighborhoods.

Mr. Christie explained the issue stems from multiple factors, including early arrival times for Miramonte students and staff. He noted the current left-turn restriction prevents legal access during early hours, and the proposed modification would alleviate this.

Vice Mayor Iverson shared student feedback that congestion on Moraga Way leads drivers to use Ardith and Ivy as alternate routes to bypass inefficient traffic signals. She and Councilmember Hoxie discussed the feasibility of alternate routes (e.g., Coral) and their impact on commute times.

Councilmember Gee suggested evaluating the stop sign configuration at Ardith and Coral, specifically considering a four-way stop. Mr. Christie confirmed this has been reviewed and a consultant will be engaged to assess the intersection.

Councilmember Hoxie raised the need to complete the sidewalk along Coral to Moraga Way. Mr. Christie stated this could be considered in a future Capital Improvement Project (CIP), pending support.

Mayor Malkani referred to cut-through traffic analysis and questioned the destinations of drivers turning left—whether they are heading to OIS or continuing to Miramonte. Mr.

Christie responded that the consultant may have used cell phone and traffic volume data, but he would need to confirm.

Regarding traffic signal timing, Mayor Malkani asked about measures taken to improve flow. Mr. Christie explained adjustments involve changing phase durations and vehicle queuing times. These are reviewed periodically and can be further evaluated.

Councilmember Riley asked whether changing the hours of the left-turn restriction had been considered as an alternative to removing the sign entirely. Mr. Christie suspected it had been discussed but would confirm with the consultant.

Mayor Malkani opened the Public Forum, and she noted written comments were also received on the matter.

Tim Silviera, 64 Ivy Drive, emphasized that traffic changes made in 1999, including the "No Left Turn" sign on South Orinda, were implemented for neighborhood safety. He urged that the sign remain in place, warning that its removal would increase cut-through traffic, and believes the traffic issue is unresolvable due to the volume of cars.

Doreen Marr, Ivy Drive, said she participated in all meetings when changes were made, cited many changes over the years with Fehr and Peers doing studies and problems with traffic, rear-ending, kids getting hit, etc., and she asked not to remove the “No Left Turn” sign.

Emily Wax-Polkari,182 Ardith Court, raised concerns about traffic congestion and safety near OIS and Miramonte Schools. She recommended staggering school start times by 30 minutes to improve the effectiveness of “No Left Turn” signs. She strongly opposed reopening Coral Drive as a cut-through due to safety risks, including a blind intersection and lack of sidewalks. She urged the City to prioritize pedestrian safety improvements on Coral Drive immediately, without waiting for lengthy studies.

Lisa Rudolph, an OIS teacher and parent, supported addressing traffic issues, particularly due to Miramonte student cut-throughs. She noted light traffic from 7–8 a.m. but heavy congestion between 8 and 8:30 a.m. She opposed changing OIS start times, citing disruption to schedules. She raised serious safety concerns about Coral Drive, citing delays, a blind hill, and heavy pedestrian use, especially by children. With many families using Coral for early OIS programs, she called for continued dialogue and comprehensive safety solutions around schools and Moraga Way.

Karen Lum-Mackley, 93 Coral Drive, a retired pediatrician, stressed student safety and supported keeping the “No Left Turn” sign. She highlighted hazardous conditions near the OIS walkway and noted her four-year involvement in traffic mitigation efforts.

Pointing out that 73% of residents were unaware of the sign, she questioned the relevance of the decades-old decision and urged for a more inclusive, transparent process instead of unilateral changes.

Chris Gurit, 60 Ivy Drive, shared results from a personal traffic survey near OIS, noting 134 vehicles passed straight through the Ivy Drive stop sign toward Miramonte, totaling over 24,000 trips annually—a major safety concern. Only 48 vehicles came from Coral Drive, showing less southern traffic. He reported 471 total trips during the count despite 800 students and 14 buses, highlighting the need to reduce vehicle volume near bus stops and sixth graders. He also compared travel times, noting it took 9 minutes via Coral versus 2 minutes via Ivy Drive, underscoring safety and time trade-offs.

Page Mittler, a parent of students at Miramonte and OIS, clarified the traffic study took place during "dead week," not finals. She shared how the “No Left Turn” restriction impacted her family, making it difficult for her Miramonte student to drop off younger siblings on time. She noted the alternative route was too slow. Ms. Mittler expressed concern that allowing left turns between 8:00 and 8:30 a.m. leads to heavy cut-through traffic from Miramonte students and questioned whether partial restrictions could effectively resolve the issue without a full-time “No Left Turn” from Moraga onto Ivy Drive.

Mayor Malkani said when Ms. Mittler said a parent’s Miramonte child who was trying to drop OIS children early, she asked and confirmed it was before 8 a.m.

Whitney Marr, 54 Ivy Drive, noted that during a Zoom call with 41 neighborhood members, the majority did not support keeping the “No Left Turn” sign, suggesting some attendees tried to flood the meeting to push their views. He emphasized the long effort put into the issue, encouraged collaborative problem-solving, and stated that input from 600 people could generate many ideas. He urged the Council not to remove the “No Left Turn” sign.

Councilmember Gee asked if there was consideration given to changing the hours of the “No Left Turn” sign.

Council discussion ensued regarding the following:

Traffic Timing & School Start Times:

Vice Mayor Iverson and Councilmembers noted that changing OIS school start times isn’t feasible due to tight schedules and impacts on teachers and after-school activities.

The 7–8 a.m. “No Left Turn” sign was originally to reduce Miramonte cut-through traffic before school but now is less effective because Miramonte starts later (8:30 a.m.).

Congestion between Ivy Drive and Miramonte is problematic, and removing the sign might increase traffic.

Traffic Study Validity:

Councilmember Riley and others questioned the timing and reliability of the traffic study, noting it was conducted during “dead week,” and existing signs may have influenced driver behavior, casting doubt on data accuracy.

Neighborhood Concerns vs. Traffic Flow:

Councilmember Hoxie emphasized protecting the quiet of Ivy Drive residents from early morning traffic, favoring keeping the “No Left Turn” sign to maintain neighborhood calm.

Vice Mayor Iverson countered that maintaining the sign solely for neighborhood quiet enjoyment isn’t sufficient justification, especially if it inconveniences those legitimately trying to get to school.

Proposed Traffic Measures:
• Trial of a “No Right Turn” on Ardith to discourage cut-through traffic, along with possible speed bumps (currently disallowed by Fire Department).

Item C.1
Packet Page 173
Orinda City Council Minutes Page 7 of 19 07.15.25
• Consideration of a 4-way stop at Ardith and Coral, pedestrian safety improvements like sidewalks, especially on Coral Drive due to children walking. • Acknowledgment that long-term infrastructure improvements will need to be budgeted and planned.

Safety Concerns:

Councilmembers agreed pedestrian safety is critical, given the number of children walking in the area and teenage drivers using shortcuts.

Balancing Cut-Through Traffic and School Access:

Vice Mayor Iverson framed the challenge as balancing Miramonte students’ shortcut traffic with the need for OIS students, buses, and pedestrians to arrive safely and on time. Councilmember Hoxie stressed that the cut-through issue and the early morning traffic calming measure are separate and should be addressed individually.

Next Steps:

The Council leaned toward approving a pilot program adjusting signs (including removing the “No Left Turn” from 7–8 a.m., trying “No Right Turn” on Ardith) with continued monitoring and community input. They emphasized the difficulty of the problem due to multiple schools in close proximity starting within the same timeframe.

City Manager Smith asked if there is a way to de-couple the “No Left Turn” on Ivy from the other safety improvements staff is also recommending tonight so the City could spend more time on that matter. Mr. Christie said it is possible; however, they might want to entertain the idea of giving staff some flexibility on adjusting the time to be more in-sync because leaving it at the same time does not serve the purpose.

Mayor Malkani suggested shifting the “No Left Turn” sign restriction to 6:45–7:45 a.m., aiming to allow OIS teachers and students to arrive by 8 a.m. while preserving a quiet period for residents.

City Manager Smith said because school starts soon, staff asked if the Council could agree on certain immediate improvements and defer the more controversial “No Left Turn” issue on Ivy Drive for later discussion. Since this was not agendized separately, staff recommended no changes to the sign tonight unless consensus emerged, and suggested a potential medium-term time adjustment.

Vice Mayor Iverson expressed concern that the Council may not be equipped to iterate effectively on this complex issue, and noted TSAC had spent two years reviewing it.

She supported staff’s full recommendation but her motion lacked a second and it died.

Councilmember Riley questioned the validity of the traffic study because the sign was in place during data collection. She proposed temporarily removing the “No Left Turn” sign for a week to gather clearer data.

Item C.1
Packet Page 174
Orinda City Council Minutes Page 8 of 19 07.15.25
City Manager Smith suggested that without a Council motion, staff could return with options including a temporary lift of the “No Left Turn” sign during the school year for better data, and explore other safety improvements. Recommended no action tonight but direction to continue study.

Vice Mayor Iverson’s Cautioned that changing signs abruptly during the school year risks confusion and traffic citations; suggested a longer-term trial (3 months) with good public communication.

Councilmember Gee emphasized desire for a comprehensive approach, including safety improvements at Coral/Ardith intersection and sidewalks, even if funding isn’t immediately available. Asked for clearer data on who needs to get where and when.

Councilmember Hoxie suggested using the 2x2 committee to discuss OIS start times and related traffic needs with the school district superintendent. Vice Mayor Iverson Preferred that TSAC directly engage with the Superintendent to avoid delays, rather than waiting for the biannual 2x2 meetings.

Mayor Malkani noted lack of majority support for any change today but recognized interest in revisiting the issue soon. Asked City Manager for guidance on what should return to Council.

City Manager Smith heard a desire for a more holistic approach, including school safety, sight distance, stop signs, sidewalks, and additional traffic analysis. She offered to return with a limited Traffic Order proposal (e.g., temporarily removing the “No Left Turn” sign) for study purposes.

Councilmember Riley requested a separate study session with the traffic consultant and staff to review the study methodology and goals. She suggested inviting the school district, but Mayor Malkani preferred the session be limited to the Council.

Vice Mayor Iverson asked City Manager to confirm with the Fire Department if speed bumps could be reconsidered on Ardith, as TSAC’s current blanket ban is due to evacuation routes, and Ardith might be an exception.

Councilmember Riley said she is struggling with how the study was done when the sign said do not turn left. Mr. Christie said in hindsight, he would have invited the traffic consultant tonight and he cannot precisely answer the question on how they do that.

He can look at windows around it and draw conclusions based on overall traffic patterns, but he acknowledged the question and was not sure how that process works.

Orinda City Council Minutes Page 9 of 19 07.15.25
City Manager Smith said if there is no desire for a Councilmember to make another motion, staff could receive direction to take this back and look at other things, such as better understanding it, put in place a limited Traffic Order during the school year so they can measure the 7 to 8 a.m. traffic and return to the Council. All of these things should not occur tonight, and if there is no thought of de-coupling the first item in the Traffic Order for the remainder of items, she would suggest not taking action on any recommendations and give staff direction. For example, there could be a temporary lift of the “No Left Turn” sign to do additional study.

Councilmember Riley asked if the Council could agendize a separate study session in the Sarge Room with the traffic consultant to get more information. She would also add direction to obtain more information from the person who conducted the study and an answer as to what they are trying to achieve and what does this achieve if the sign is taken away.

Councilmember Hoxie suggested the school district also be invited for the study session, and Mayor Malkani was opposed to this and felt strongly that it should only be the City Council. She recommended obtaining more data on the number of students at Miramonte and OIS have reasons to be at school before regular start times.

Vice Mayor Iverson asked before the meeting if the City Manager could reach out to the Fire Department. She knows TSAC has a blanket “No speed bumps” rule so she did not want to get a “no” before asking the question because Ardith is so different from the evacuation route problem that created that prohibition, so this would be a very helpful solution to discuss this.

City Manager Smith asked if the Council was interested in the limited Traffic Order as part of the analysis or just talk about it and give further direction on that from the study session.

Mayor Malkani said Items 3 and 4 are the Southway Court and Whitehall Drive “No Left Turn” signs, and it is changing the hours from 7 to 8 to 7:30 to 8:30 a.m. She thought she heard consensus on that. Vice Mayor Iverson said they could change the time, but all Councilmembers agreed to evaluate it with the other items.

City Manager Smith confirmed staff has direction to agendize a study session and hold more discussion around the issue.

Subject: Re: OIS Parent Input—No Left on Ivy Drive
Brandyn, Yes, most definitely share my email far and wide. There are several important additional considerations that I am concerned have been overlooked:
• Forcing OIS staff and zero period parents to turn left at Coral Drive is significantly less safe, and more disruptive to the flow of traffic on Moraga Way. While Coral Drive does have a stoplight, it does not have a left turn lane. Traffic backs up (sometimes unsafely) behind cars attempting to turn left, and I've personally been forced to turn on a yellow light multiple times, which increases the likelihood of a car accident if oncoming traffic does not stop. I've also been honked at and nearly rear-ended by cars tailgating on Moraga Way as I slow to a stop at Coral Drive waiting for a break in traffic to safely turn left. Further, there are often children making their way to early dropoff at Del Rey Elementary School during this time (Dolphin Club opens at 7 a.m. every school day).

In contrast, given the natural hills on Moraga Way approaching Ivy Drive, there is often a break in cars allowing a safe left turn onto Ivy Drive. Ivy Drive is also sufficiently removed from Del Rey as to rarely have pedestrians between 7 and 8 a.m.
•
• The carbon impact of all OIS staff and zero period families having to travel an extra 1.4 miles each day to school is significant. Assuming, conservatively, that just 100 cars are impacted (the true number is likely higher), times 180 school days per year, that's 25,200 extra miles, representing

10.2 metric tons of carbon dioxide. This additional CO2 provides measurable societal damage. In addition to negative environmental impact, the extra 1.4 miles in driving adds at least 3 minutes to each trip. That's 54,000 minutes, or a staggering 900 hours of productivity lost per year. Again, this is likely an underestimation as I suspect the true number of daily impacted drivers exceeds 100. •
• Finally, "protecting" Ivy Drive residents who live north of OIS gives zero consideration to residents who live on Coral Drive. Coral Drive is steep, includes blind spots at the top of the hill, and does not have the same traffic calming measures in place on Ivy Drive. I am all for stopping drivers who inappropriately use a residential neighborhood as a cut-through to drive to a different destination.

That was the purpose of the original sign, and is no longer a reality. Instead, the sign now discriminates against and negatively impacts those staff and families who are legitimately driving to Orinda Intermediate School each morning. If neighbors cannot abide by school traffic, they should consider moving. OIS has been open for over 50 years. School traffic should not be a surprise to residents on Ivy Drive, and a desire to re-route legitimate school traffic to a less safe route is frankly the epitome of NIMBYism.

Subject: OIS Parent Input—No Left on Ivy Drive
Dear Council Members,
I’m an OIS parent, and writing to request your support for removing the outdated “No Left Turn” sign at Moraga Way/Ivy Drive. Our daughter, who is in 7th grade, had zero period Jazz Band last year, and dropoff by 7:30 am was made significantly more challenging given the no left on Ivy. We live in North Orinda, and driving past OIS and Del Rey to turn left at Coral Dr. needlessly added both time and mileage to our daily routine.

Please support the sound recommendations of the TASC and city staff, who devoted significant time and resources to studying this issue and correctly concluded the sign does more harm than good, and no longer serves its original purpose. If you choose to continue to ignore TASC recommendations, I kindly request a written response detailing the basis for this decision, and information on how this decision may be appealed.

Thank you for your attention to this matter,

EXTERNAL EMAIL - This email was sent by a person from outside your organization. Exercise caution when clicking links, opening attachments or taking further action, before validating its authenticity.

Dear City Council and Planning Commission members,
I am writing to voice my support for the removal of the “No left turn between 7-8am” on Ivy Drive and Moraga Way.

For the last two years we have complied with this sign in order get our current OIS student to school on time for her zero period start. This has had a significant impact on our time during busy working day commutes, safety, carbon footprint, and even academic performance (accumulated tardies due to additional length of time it takes to get to school in the morning at this hour).

Many mornings we have witnessed the cumulative traffic impact this unnecessary rerouting has on the rest of the community including long back ups on Moraga Way as we wait to turn left on Coral Drive, increasing traffic around the El Camino and Moraga Way intersection where children are making their way to Del Rey elementary school, as well as occasionally having to make quick and less than ideal left turns on Coral Drive with oncoming traffic approaching.

Given the Orinda City staff and the Traffic Advisory Safety Committee have concluded that the sign no longer serves its original purpose (deterring Miramonte traffic from cutting through Ivy Drive before high school start times changed), we especially hope removal of this sign will be acted on expeditiously.

We anticipate a continuing need to arrive at OIS between 7-8am during school days for the next ten years as we have 4 remaining children who will attend OIS and would greatly appreciate removing this unnecessary barrier to safely and timely getting them to school.

Thank you for your consideration,
Connie and Brian Park

Petition to Install a Four-Way Stop Sign at
Ardith and Coral
Many children walk to school in the Ivy Drive neighborhood. Children use Coral Drive to get to Del Rey, OIS, and Miramonte. The intersection of Coral and Ardith is at the crest of a hill with limited visibility for drivers approaching on Coral from both directions. Children coming from Ardith Court, the south side of Coral and Carisbrook need to cross Coral at Ardith, and it is difficult for drivers to see a pedestrian in the intersection while approaching. In addition, if the city proceeds with the plan recommended by the TSAC to remove the No Left Turn sign from Moraga Way to Ivy Drive and install a No Right Turn sign on Ardith Drive at Ivy Drive, this could lead to an increase in cut-through traffic in the mornings on Coral Drive. A four-way stop sign is necessary to give pedestrians a safe place to cross Coral Drive and to slow any cut-through traffic traveling on Coral for the safety of pedestrians in the intersection and pedestrians on Coral between Ardith Drive and Moraga Way.

By typing my name below, I am confirming that I am in favor of installing a four-way stop at this intersection.

The visibility as you drive up Coral is definitely a
challenge. I've had several incidents where I've
had to hit my brakes because of an Amazon truck
crossing the street unexpectedly, or a car
dropping off an OIS student on the other side of
the crest, or just saw a pedestrian. And that's
coming from someone who is a cautious driver. I
worry about the potential for increased traffic
from tardy Miramonte students or other drivers
frustrated with the Moraga Way traffic who use
Ivy and Coral as a cut-through and drive a bit
faster than expected.

Making a left turn from Coral into Ardith can be
scary as people are often coming up Coral fast
and it is difficult to see oncoming traffic.

consistently for the past 7 years. Walking
conditions on Coral are very unsafe and MANY,
MANY children are walking to school along this
route. This stop sign is needed for several
reasons. First of all, it is a blind intersection. You
can't see anything until you are at the top of the
hill. Second, high school drivers are driving at the
same time that younger children are walking. The
high schoolers speed down Coral like they are on
a race track. This stop sign will force them to
slow down a bit. Please install this stop sign AND
finish the sidewalk along Coral before a tragedy
occurs. Thank you.

I have lived in Orinda for 17 years and we have
witnessed excessive speeding on a daily basis - middle school and high school driving to OIS and Miramonte . We have asked about speed bumps
on Coral drive to slow down traffic for safety
purposes . We have also inquired about additional
safety measures for families and students
walking up and down the street - there is limited
sidewalk on Coral Drive . This is a heavy traffic
street that truly needs safety improvements

Dear City Council and Planning Commission, I am an Orinda resident who commutes to work every day using Moraga Way to Los Perales Elementary School. For the past 15 years, I’ve been frustrated driving to work because I leave around 7am and there’s lights traffic, yet I can’t make a left onto Ivy Dr. I can understand when the three schools, Del Rey, Miramonte and OIS, had conflicting schedules but it’s no longer an issue. I find I create more of a traffic issue making a left onto Coral Drive because there’s no left turning lane, like there is for Ivy Drive.

Please consider removing the no left turning lane onto Ivy Drive during 7-8am.

Sincerely,
Suzanne Tom

Dear Mayor Brandyn Iverson, Vice-Mayor Darlene Gee, and Council Members Latika Malkani, Cara Hoxie, and Janet Riley:

As an Ivy Drive resident with involvement in the City of Orinda’s (City’s) past traffic studies, I am writing to you regarding traffic and pedestrian safety for residents in the Ivy Drive neighborhood and the increased volume of cars travelling to south Orinda, particularly in the morning hours.

As you well know, there has been a wrangling of issues on increased cut-through speeding traffic to Miramonte High School (MHS) on residential streets in our neighborhood, and the three “No Left Turn” sign restrictions on Moraga Way with the change in the schools’ bell schedules.

The recent Traffic Safety Advisory Committee (TSAC) one-day study, along with its proposal that went before City council to remove the NO LEFT TURN sign at Ivy/North (on a trial basis) and changing the times at the NO LEFT TURN signs at Southwaite and Whitehall, has caused much debate. I was pleased to see that the Council recognized that there were outstanding issues that needed further study and moved to delay its July 2025 vote on TSAC’s proposal for further review.

With the help of State funding received 25 years ago, the City of Orinda was able to implement the first phase of a very comprehensive plan (which included the three NO LEFT TURN signs on Moraga Way) for pedestrian safety and traffic mitigation in south Orinda. Attachment A to this email is a letter to State Senator Richard Rainey dated April 20, 2000, outlining the City’s, OUSD, and Ivy Drive Neighborhood’s intent and mutual resolve to improve school safety if funding could be provided.

My recommendation: The long-standing agreement on “safe routes to school” with the City of Orinda, OUSD, and Ivy Drive area residents must continue to be embraced for the safety of our neighborhood. The three Moraga Way NO LEFT TURN signs were put in place to keep our children and residents safer as they Item C.1

History of Pedestrian and Traffic Safety Work in Ivy Drive and South Orinda My name is Doreen Marr, and I have been a resident in Ivy Drive since 1980. Together with my husband, we raised our two daughters (who attended Del Rey, OIS, and Miramonte) in this home. As a long-time Ivy resident, I’ve seen the City of Orinda become incorporated in 1985, observed the gradual development and growth of the City, and noticed the surge in student population at Orinda Intermediate School (OIS) after Pine Grove Intermediate merged (in 1975) with Inland Valley (now OIS) to become the only intermediate school serving the City.

In each subsequent year with population growth and more housing development in Orinda, followed an increasing OIS and Del Rey population, as well as an increasing Miramonte High School (MHS) population using Ivy Drive as a cut-through passage to the Miramonte campus.

I witnessed the evolution of: increased reckless driving, daily dangerous situations of speeding cars, students walking intertwined with cars, buses, bikes, and garbage trucks on the street and nearly being hit, near rear-endings of cars as residents backing out of their driveways, increased rude behavior by frustrated and angry students and parents (even saw a student walking and hit to the ground by a reckless driver; fortunately not severely injured), south Ivy streets all the way to Arroyo Drive and adjacent side streets were flooded with student cars serving as an overflow parking lot for MHS (sadly, residents weren’t getting their mail as the postal service couldn’t gain access to mailboxes, emergency vehicles couldn’t reach residents in a timely manner, and elderly residents couldn’t have their friends visit as they would have to park too far away), 75% of Orinda students coming to south Orinda daily, with studies counting nearly 4000 cars daily; all these disruptions to the Ivy Drive neighborhood caused pandemonium.

Ivy Drive residents became outraged as the neighborhood streets were becoming increasingly dangerous for students and residents for walking, biking, driving to school or work. As a neighborhood of 600+ homes, we started organizing to be heard by our local officials. As a retired environmental engineer with experience in City Planning, I understood organizations and local government. So, in 1995, I began my outreach to the Orinda City Council and staff, City Manager, City Police, City Fire Department, OUSD, OIS, and Miramonte High School, which was the start of a 9-year long effort in seeking traffic and pedestrian safety improvements in south Orinda. At the time, Police Chief Dan Lawrence would tell the residents “Do not let your kids walk or bike to school, it’s too dangerous.” After 2 years of writing numerous letters for help, making phone calls, and attending countless meetings with the City of Orinda staff, City Manager, OUSD, OIS, MHS, and City Police Department, we were finally able to receive focused attention to the Ivy neighborhood problems and concerns. A very extensive stakeholder group in Orinda ---City Planning, City Item C.1
Packet Page 206
Continued - Attachment B (Page 2 of 3)
Public Works and Engineering, City hired traffic engineering consultants - Wilbur Smith (1997) and Fehr and Peers (1999), school districts - OUSD Superintendent, OIS Principal, and MHS Principal with Acalanes, City Police Chief, City Fire Department, and several Ivy Drive residents ---came together to learn about the issues, address traffic problems, assess data collected, and brainstorm traffic and pedestrian safety mitigating measures. This stakeholder group known as the Ivy Drive Neighborhood Traffic Committee met every two weeks for almost 4 years, and with the completed traffic engineering studies they were able to identify traffic mitigation and pedestrian safety improvements along the Moraga Corridor and Ivy Drive neighborhood.

Potential traffic mitigation and pedestrian safety improvements were now identified, but the next hurdle was how to fund these improvements. At the time, the City and OUSD/MHS of Acalanes indicated they had no funds. With determination to make our neighborhood safer, Ivy area residents Karen Lum, Tim Silveira, and myself earnestly took upon the task of seeking out funds with our legislative offices and gratefully received the attention of State Senator Richard Rainey. The residents provided documentation and photos in several meetings with Senator Rainey. Together with the City, OUSD and the Ivy Drive neighborhood, Senator Rainey was successful in locating funds for our highest priority traffic and pedestrian safety improvements in our neighborhood and around the four south Orinda schools. Attachment A to this email is a letter to Senator Rainey dated April 20, 2000, outlining our community’s intent and mutual resolve to improve school safety if funding could be provided.

With $600,000 received from the State, along with City funds, the City was able to start a first ever major launch in rehabilitating south Orinda to help alleviate traffic and pedestrian safety issues in our neighborhood. Once funds were received, it took almost 2 years to put in place the highest priority improvements, as listed below:

Infrastructure improvements
• Built a bus turnout at OIS.
• Design/Installed a right turn lane into MHS.
• Built a sidewalk along Coral from Ivy to Ardith
• Installed an asphalt roadside curbing along Moraga Way, starting at Coral, creating a safe lane for students walking to Del Rey
Traffic calming measures.
x Constructed Bulb Outs at Upper OIS, to narrow roads to slow down traffic. x Reconfigured the stop light at South Ivy/Moraga way, for better MHS traffic flow. x Improved street markings along Moraga Way corridor and Ivy Drive Item C.1
Packet Page 207
Continued - Attachment B (Page 3 of 3)
x Added speed cushions at key intersections along Ivy Drive x Installed new signage to curb traffic flowing on to Ivy Drive. Specifically: NO LEFT TURN Signs at Ivy, Southwaite, and Whitehall. This was a stop gap measure until a traffic signal could be installed at North Ivy to pulse traffic along Moraga Way. x Installed stop signs and crosswalks at Coral and Eastwood, at lower OIS. x Restored safety and property rights to South Ivy residents up to Arroyo Drive by installing “No Parking” restrictions. Worked with the City of Moraga to help us solve the parking problems at South Orinda, as the south side of the street on Ivy Drive is the limits of Moraga.
x Worked to support Measure J (2008) an extension to Measure C (1988) for voter approval for funding transportation and growth management in Contra Costa, especially for the Bus program.
x Reduced garbage truck congestion on Ivy Drive streets, by reaching out to Allied Waste Systems, Inc. and Valley Waste Management (Now Republic Services) to adjust trash pickup times to not conflict with school peak hours, especially morning hours.
x OIS principal established protocols for student drop-off/pick-up for the traffic circle within the school.
x MHS educated its students on parking restrictions on South Ivy, encouraged carpools and bus usage.
x City provided Police Enforcement around the schools, especially at the NO LEFT TURN Sign at Ivy/North. This took about a year for the community to learn and abide by these NO LEFT TURN restrictions.

All the prioritized infrastructure improvements, traffic calming measures, and school district outreach to its students and parents have significantly improved the safety of the students and the residents of our neighborhood. Neighborhood residents began to feel more secure and safe to let their children walk and bike to school.

As the City concluded this first phase of work, residents believed the city would continue its efforts in future planning and investing in more infrastructure projects to further improve the traffic and pedestrian pathways along the Moraga Way Corridor for the safety of this community. Capital improvement projects identified in past studies for future work were:
x Build a second entrance at Miramonte High School from Moraga Way x Install a traffic signal at Ivy Drive/North
x Establish a shuttle service along Moraga Way

Dear Council members,
I am writing to support the removal of the No Left Turn between 7 and 8am sign from Moraga Way onto Ivy Drive. This sign adds unnecessary time and mileage for OIS families dropping off their children in the morning. It leads to unsafe behaviors, with people doing illegal u-turns or dropping their child off on Moraga Way, where there is no safe place for children to cross. Families who drive all the way to Miramonte to turn left onto Ivy at the light then only add to the already heavy high school congestion.

We are asking that you please consider removing this sign ahead of next school year.

Thank you,
Marie Olson

Ryan, Thanks for keeping me on your mailing list. As you know I have been concerned for many years about people using Ivy Drive to bypass the line into Miramonte. Only a certain number of cars can get into Miramonte per minute and the bypasses actually decrease the number by triggering the light so they can get off Ivy Drive. The extra cars on Ivy Drive are a safety hazard for those walking and biking from the Ivy Drive neighborhood and those walking their dogs before work. I would be against making a change to help those who refuse to take their turn on Moraga way that would adversely affect the Ivy Drive neighborhoods. If the timing on the "no left turn" signs has not yet been updated to match the school hours then that should be done.

I won't be able to attend the meeting but i believe you fully understand the situation and will represent my views. If you wish feel free to share my thoughts with those making the decision but I believe coming from you they will have more impact. Pete Williams (South Ivy Drive resident).

Hello Ryan,
I’m unable to attend the upcoming City Council meeting, but I wanted to share my support and involvement. I have completed the surveys and signed the petition regarding the proposed traffic changes.

From what I’ve observed, either adjusting the timing or removing the restriction altogether would meaningfully improve traffic flow in the area. I am also very supportive of installing a 4-way stop sign at Coral and Ardith, as I believe it would enhance safety and consistency at that intersection.

Thank you for your continued dedication to this matter. Our community truly appreciates the time and effort you’ve invested.

Sara Megson
