Public Works Agreement with Interstate Striping, Inc. for enhancing the Avenida Traffic Circles (page R-1) EXECUTIVE SUMMARY: • In 2021, Public Works received requests to investigate traffic conditions on Avenida Classica between Crest Road and Los Verdes Drive. As a result, the City contracted with the traffic engineering consultant to conduct a traffic study. • Based on an alternative recommendation from the traffic study, the TSC recommended, and the City Council approved , the installation of the Avenida Classica Traffic Circles Pilot Project. • Installation of the traffic circles was completed on October 15, 2024 and approximately six months thereafter, a post-installation speed study found that speeds were reduced on Avenida Classica by 7 to 9 miles per hour on average. • Subsequently, Staff received a petition from some area residents requesting to remove the traffic circles along Avenida Classica, expressing the following concerns: o Potential safety risks: increased collision risks and higher crash probability, visibility issues, pedestrian and cyclist safety, potentially unlawful speed limit sign removal, emergency vehicle obstructions, and no justifiable crash history. o Deviation from due process and legal liability to the City. o Ethics violations and conflicts of interests. 2 o Cost burden and transparency. • Staff presented the petition and a corresponding Staff Report to the TSC for consideration. The Staff Report concluded that there was no increased safety risk, deviation from due process, legal liability, ethics violation, conflict of interest, or lack of transparency (Attachment C). Additionally, the Staff Report recommended various measures to address the design and operational concerns presented in the petition based on the Project Traffic Engineer’s recommendations. • On November 3, 2025, the TSC passed a motion, with three members in favor and two opposed, to recommend to the City Council continuing with the traffic circle project with the improvements recommended by Staff to help the community navigate the circles. • The City Council is being asked to direct Staff to either remove the traffic circles and discontinue the pilot project or implement the recommended improvements and continue the project. BACKGROUND: Since 2021, Public Works received requests to investigate traffic conditions on Avenida Classica between Crest Road and Los Verdes Drive. Residents reported concerns about speeding, cut-through traffic, and erratic driving along Avenida Classica and surrounding roadways. The City contracted with KOA, a traffic engineering consultant firm, to perform a traffic study. Staff and the traffic engineering consultant met with the community, who brought up the following main concerns: • Speeding – Residents raised concerns over aggressive and fast-driving motorists at various times of the day on Avenida Classica, likely those driving to and from the nearby Los Verdes Golf Course. • Driver Safety – Residents reported a number of traffic collisions on the street, resulting from erratic driving and/or inattention to the roadway and roadside conditions within the neighborhood context. • Various collisions and “close-calls” were reported between aggressive/speeding drivers and other cars driving on Avenida Classica, parked cars along the street, and drivers backing out and heading into driveways. • Pedestrian Safety – Residents expressed concerns about speeding motorists not safely yielding to and/or navigating around pedestrians crossing the street. • Blind Curves – Concerns were raised about traffic safety due to visibility conflicts between motorists traveling along the horizontal curves, between motorists approaching in the opposite direction, and motorists on the street conflicting with motorists backing out of residential driveways. The results of the study provided numerous recommendations and an alternative for the TSC to consider, with the primary recommendation being to install traffic diverters to 3 prevent through traffic from using Avenida Classica to get to the Los Verdes Golf Course (Attachment F). In keeping with the Public Works Department’s practice of notifying residents within 500- foot radius of proposed projects, on July 7, 2023, notifications were sent to residents adjacent to Avenida Classica, Avenida Esplendida, Avenida Celestial, Avenida Selecta, Los Verdes Drive, and Crest Road up to Avenida Esplendida (Attachment P) inviting input on the upcoming TSC meeting (Attachment M). At its regular meeting on July 24, 2023, the TSC opted not to proceed with the traffic diverters and to instead recommend that the City Council approve the implementation of traffic circles along Avenida Classica. On September 18, 2023, notifications were sent to residents within a 500-foot radius of Avenida Classica inviting input on the upcoming City Council meeting (Attachment N). At its October 3, 2023 meeting, the City Council considered TSC’s recommendations, Staff recommendations, and public testimony. After considering the information presented that evening, the City Council approved the installation of the traffic circles pilot project. Following the City Council’s approval of the traffic circle pilot project, the City contracted with the traffic engineering consultant, General Technologies and Solutions (GTS), which developed the traffic circle engineering design. The design development process included coordination with the Los Angeles County Fire Department (LACFD) to ensure that the proposed traffic circle design elements would not impede or conflict with their fire/emergency operational capabilities and response time. Staff approved the final plans for installation upon receipt of LACFD’s written concurrence (Attachment G), and construction was scheduled for the fall of 2024. On October 3, 2024, Staff notified the community that the Avenida Classica Traffic Circle Pilot Project (Pilot Project) will be implemented in accordance with City Council approval (Attachment L). The community notification expanded upon the earlier notifications to add residents adjacent to Crest Road up to Avenida Tranquila, Avenida Magnifica, Avenida Refinida, and Avenida Tranquila (Attachment P). The pilot project officially commenced on October 15, 2024, with the installation of the traffic circles at Avenida Classica/Avenida Celestial and Avenida Classica/Avenida Esplendida using temporary materials, see Figure 1. [CONTINUED ON NEXT PAGE] 4 Figure 1 – Avenida Classica Pilot Project Traffic Circles Installed The City’s traffic consultant conducted a speed study approximately 6 -months after the installation of the traffic circles to evaluate the traffic calming effects of the traffic circles. On June 16, 2025, Staff notified the community , using the expanded notification map (Attachment P), of the upcoming TSC meeting (Attachment K), during which an update on the Pilot Project would be presented. At the June 30, 2025 TSC meeting, staff reported the results of the Pilot Project concluding that the installation of the temporary pilot traffic circles was effective in reducing vehicle speeds along the study segment of Avenida Classica. Speed data was collected in June 2021 and December 2022, prior to the traffic circles being installed and then again in March 2025, after the traffic circles were installed. Speed data indicated an average reduction of 7 to 9 miles per hour when compared to pre-installation conditions. Based on the findings of the June 27, 2025, GTS Memorandum: Avenida Classica Before- and-After Speed Study (Attachment E), Staff recommended, and TSC concurred, that five modifications to the traffic circles should be implemented as follows: • Install red curb at the intersection of Avenida Classica and Avenida Esplendida; • Add a Pedestrian Ahead sign on Avenida Classica at the start of the red curb on the eastbound approach of Avenida Esplendida; • Install circular direction arrow signs and/or ONE WAY signs to indicate travel direction; • Modify striping along Avenida Classica to enhance the entry to the traffic circle ; and • Increase the existing 20-foot diameter to 22-feet. While engineering of the recommended modifications was underway; on September 15, 2025, Staff received a petition (Attachment A) from a group of area residents to remove the traffic circles pilot project listing the following concerns: • Safety risks (top priority); • Deviation from due process; • Ethics and conflicts of interest; • Legal liability to the City; and, 5 • Cost burden and transparency. DISCUSSION: Summarized below are the petitioners’ concerns along with Staff’s responses (which incorporate some GTS recommendations) for the City Council’s consideration: Petition Elements A. Petitioners’ Concern of Safety Risks The petition identifies the following items as safety risks: increased collision risks and higher crash probability, visibility issues, pedestrian and cyclist safety, potentially unlawful speed limit sign removal, emergency vehicle obstructions, and no justifiable crash history. Increased Collision Risks and Higher Crash Probability Traffic circles are commonly used and an industry-accepted traffic calming measure, particularly effective in urban settings. Studies have shown no increase in collision risk associated with their use. The Federal Highway Administration (FHWA) and the Insurance Institute for Highway Safety (IIHS) have consistently found that traffic circles have been shown to decrease crash severity by eliminating high-speed, right-angle, collisions by forcing drivers to slow down as they approach the intersection. Although the Pilot Project traffic circles are currently controlled by two-way stop signs on the side streets, both intersections could be converted to an all-yield configuration to minimize confusion regarding right-of-way. This modification would require drivers on Avenida Classica to yield to vehicles already within the intersection, consistent with the operation of modern roundabouts. Creating an all-yield condition at the traffic circles is part of the improvements recommended by the TSC in conjunction with continuing the Avenida Classica traffic circles project. An example of additional signage is shown below in Figure 2. Figure 2 – “Yield” Signs for Traffic Circle Entrances Source: Google 6 Visibility Issues As noted in the June 30, 2025 TSC Staff Report (Attachment D), the City’s traffic engineering consultant conducted a sight distance analysis and determined that parked vehicles along Avenida Classica, approaching Avenida Esplendida from the west, could restrict visibility. To address this issue, Staff recommended, and the TSC concurred, extending the existing red curb along Avenida Classica to prohibit parking and improve sight distance at the intersection. Due to visibility concerns, this improvement was installed on August 24, 2025. Pedestrian and Cyclist Safety The new traffic circles have proven to be effective in reducing speeds, thereby creating a safer environment for pedestrians and cyclists travelling along Avenida Classica. Studies have shown the risk of serious pedestrian injury or fatality exponentially decreases when speeds are reduced from 30 mph to 25 mph; 20 mph has a 95% survivability rate, whereas 30 mph has as 55% rate. The City’s traffic engineering consultant also recommended, and the TSC concurred, installing a “Pedestrian Ahead” sign on Avenida Classica approaching Avenida Esplendida. Further, the traffic circles were designed to allow vehicles to remain within the intersection without encroaching on pedestrian paths of travel. Potentially Unlawful Speed Limit Sign Removal Based on a review of Google Street View imagery, the 25 -mph speed limit sign was removed, by someone other than the City, sometime between January 2018 and December 2023. Public Works has no record or information regarding the reason for or circumstances surrounding its removal. In accordance with the California Vehicle Code, §22352 sets the prima facie speed limits: Twenty-five miles per hour: (1) On any highway, in any business or residence district unless a different speed is determined by local authority or the Department of Transportation under procedures set forth in this code. By Government code, there is no requirement to install or post speed limits in residential districts as they default to 25 mph. Accordingly, most residential streets in the City are not posted with 25 miles per hour signs. In addition, GTS did not include reinstallation of the 25 mph speed limit signs as part of the recommended improvements. Based on these factors, Public Works does not plan to replace the signs. Emergency Vehicle Obstructions As noted in the November 3, 2025 TSC Staff Report (Attachment C), Staff coordinated with LACFD during both the design and installation phase of the traffic circles (Attachment G). LACFD visited the traffic circles in March 2025, navigating the two intersections using both a standard-size fire engine and a longer articulated ladder truck (Attachment H). Prior to the November 3, 2025 TSC meeting, Staff followed up with LACFD and reconfirmed that they have responded to calls on Avenida Classica since the installation of the Pilot Project and the traffic circles are no problem for their trucks (Attachment I). Figure 3: LACFD official and articulated ladder engine 7 No Justifiable Crash History A specific crash history threshold is not commonly used as an eligibility criteria for the installation of traffic calming measures in the same way as it is used for installing traffic control devices such as traffic signals. Rather, speed data and user experience is used as the basis for considering traffic calming measures. For the Avenida Classica corridor, the initial traffic study confirmed speeds 7 miles per hour or greater over the speed limit . For residential streets, the installation of traffic calming measures is commonly used by many jurisdictions to mitigate such speeds. B. Petitioners’ Concern of Deviation from Due Process The petition states that the TSC introduced and approved the circles without a required public petition and public engagement. It further states that the TSC failed to adhere to City procedures and that community engagement was ignored. While no specific petition was submitted for the installation of traffic circles, a petition requesting traffic diverters and traffic calming initiated the initial KOA traffic study along Avenida Classica, in which, traffic circles were discussed as a potential traffic calming measure. The petition was included as an attachment to the July 24, 2023 TSC meeting staff report (Attachment Q). Staff notes that at the time that the TSC considered this item, the City practice was not to use a petition process nor minimum daily traffic criteria. This practice was applied to other traffic calming requests considered by the TSC during that timeframe. More recently, during 2024, the TSC formally adopted a specific petition process, which has been subject to ongoing TSC modifications. At that meeting, the TSC recommended to the City Council installation of traffic circles as an alternative to traffic diverters. Additionally, as previously noted, a community notification was distributed on July 7, 2023, informing the public of the July 24, 2023 TSC meeting. The TSC serves as an advisory body to the City Council and is not subject to any formal legal procedures or requirements under the Rancho Palos Verdes Municipal Code (RPVMC). 8 Including tonight’s meeting, Staff sent out community notifications on six separate occasions, five of which specifically invited residents to provide input on traffic circles along Avenida Classica. C. Legal Liability to the City The petition asserts that there is elevated legal liability to the City associated with the traffic circles. The City acted based on recommendations from a licensed Professional Traffic Engineer. Furthermore, under California State Law, the doctrine known as “design immunity” applies when a governing body, such as the City Council, formally approves a public improvement. Under Government Code Section 830.6, the City is immune from liability for an injury caused by a plan or design of public property (in this case the design of traffic circles) if these elements are established: (1) the plan or design was approved before construction by either the City’s City Council (or an employee with authority to approve designs [or was built in conformity with standards so approved]); and (2) there is some evidence that the City’s approval was reasonable. D. Petitioners’ Concern of Ethics Violations and Conflicts of Interests The petition asserts that a TSC committee member lobbied the committee, creating a perception of possible self-dealing. At the time, a previous member of TSC lived along Avenida Classica during consideration of traffic calming measures and implementation of the Pilot Project. However, the previous TSC member recused himself from the TSC’s discussion, deliberation, and vote on proposed traffic calming measures. The former TSC member spoke as a private resident, expressly stating that he was doing so. E. Petitioners’ Concern of Cost Burden and Transparency The petition states that no transparency has been provided by the City on the costs and uncertainty of the traffic circles. The petition further claims that there will be a maintenance burden on the residents despite not requesting or supporting the circles. The cost to design and construct the initial pilot traffic circles was approximately $40,000. Staff are still obtaining quotes from vendors for the improvements, which are anticipated to cost in the range of approximately $15,000. Similar to other traffic calming improvements, the HOA is not responsible for maintenance of the traffic circles. Measures to Address Design and Operational Concerns All design and operational concerns raised in the petition were reviewed by GTS. Staff concluded that all design and operational concerns have been, or can be, addressed through appropriate engineering measures including installing all all-yield control signs (Attachment B). Most of these were already considered and incorporated into the proposed modifications reviewed and recommended by the TSC at its June 30, 2025 meeting. A summary of the petition’s design and operational concerns and the recommended City-engineering responses and measures are listed below: 9 • Increased Collision Risks and Higher Crash Probability o Mitigation measures: Modifications such as splitter island delineators, botts dots, advanced signage, all-yield control, etc. ▪ Not completed - awaiting outcome of City Council direction on petition. • Visibility Issues o Mitigation Measure: Extend red curb ▪ Completed. • Pedestrian and Cyclist Safety o Mitigation Measures: splitter island delineators, botts dots, advanced signage, all-yield control, etc. ▪ Not completed - awaiting outcome of City Council direction on petition. • Potentially Unlawful Speed Limit Sign Removal o Mitigation Measure: Although not required by the California Vehicle Code, a 25-mph speed limit sign can be re-installed along Avenida Classica at an appropriate location as determined by a traffic engineer. ▪ Not completed - awaiting outcome of City Council direction on petition. • Emergency Vehicle Obstructions o Mitigation Measure: Although the Fire Department stated on three separate occasions that the traffic circles do not affect their response, coordination will continue as needed. ▪ Ongoing. Traffic Safety Committee At the November 3, 2025 TSC Special Meeting, Staff presented the petition and a Staff Report addressing the concerns raised in the petition (Attachment C). In advance of the TSC meeting, on October 20, 2025, notifications were sent to the community, using the expanded map (Attachment P), inviting input on the upcoming meeting (Attachment J). The TSC received public comment and passed a motion with three members in favor and two opposed to continue with the traffic circle project, with improvements, recommended by Staff with optimized signage for early notification of circles being ahead and anything else that might help the community navigate the circles. ADDITIONAL INFORMATION: Council Meeting Notification In advance of tonight’s City Council meeting, on February 13, 2026, notifications were sent to the community, using the expanded map (Attachment P), inviting input on tonight’s meeting (Attachment O). 10 TSC Attendance at City Council Meeting The TSC Chair and other members of the TSC were invited to attend tonight’s meeting to provide additional information regarding their discussion and to respond to any questions from the City Council. CONCLUSION: The City Council is recommended to consider a petition to remove the Avenida Classica Traffic Circles Pilot Project and TSC’s recommendation to continue with the Pilot Project with modifications, and to direct staff to either remove the traffic circles and discontinue the pilot project or implement the improvements recommended by Staff to enhance navigability of the project. ALTERNATIVES: In addition to the Staff recommendation, the following alternative actions are available for City Council’s consideration: 1. Remove one traffic circle while continuing with the other traffic circle. In this case, Staff would recommend keeping the traffic circle at the intersection of Avenida Classica and Avenida Esplendida because most of the original traffic complaints were focused on the segment from Avenida Esplendida to Los Verdes Drive; or 2. Take other action as deemed appropriate. 11 September 15,2025 To: Rancho Palos Verdes Traffic Safety Committee, City Council, and Department of Public Works Attached please find a copy of a petition physically signed by residents at 32 separate residences in proximity to the recently-installed traffic circles at the intersections of Avenida Celestial & Avenida Classica and Avenida Esplendida & Avenida Classica who are seeking that these dangerous traffic devices be removed from our community. A map of the residences expressing support for the traffic circle removal can be found on page 3. This petition follows a digital petition where 50 respondents from 34 households sought their removal. Key Concerns 1. Safety Risks (Top Priority) • Increased Collision Risks: Vehicles drive straight through circles without slowing or yielding, defeating intended safety functions. • Visibility Issues: Traffic circles combined with blind curves and the steep slope combine to make more significant and dangerous visibility issues, heightening risks for pedestrians, cyclists, and drivers. • Pedestrian and Cyclist Safety: Lack of sidewalks forces pedestrians onto roads closer to traffic, and since circles result in cars driving closer to curbs, residents report frequent near-accidents. • Higher Crash Probability: Traffic circles increase risk for T-bone collisions compared to previous 2-way stop-sign intersections. • Potentially Nefarious and Criminal Speed Limit Sign Removal: A speed limit sign was removed during the time period speed studies were conducted to justify device installation. While Public Works claims they did not remove the sign, they also have made no effort to replace the sign a full two years after being notified that it is missing on multiple occasions. • Emergency Vehicle Obstruction: Circles may delay critical response times for large vehicles like fire trucks. • No Justifiable Crash History: City’s own crash data shows negligible accident history, undermining safety justification. KOA traffic study showed no accident history. 2. Deviation from Due Process • Improper Committee Procedure: The Traffic Safety Committee introduced and approved circles without required public petition and engagement. • Failed Mandatory Criteria: Did not meet minimum daily traffic (1,418 vs required 1,500) or eligibility point score (21 vs required 51). • Violation of Resident Approval Process: Required petition with 60% local support never obtained or pursued. A-1 • Lack of Transparency: Circles installed in locations that differed from the alternative proposal prepared by the Public Works Department in its public agenda at meeting where Traffic Safety Committee approved. Further, Committee adopted its own proposal without any public comment. 3. Ethics and Conflicts of Interest • Conflict of Interest: Then-committee member David Tomblin publicly lobbied the committee he served on for traffic devices to be installed on his street Avenida Classica, creating perception of possible self-dealing. One traffic circle was installed directly in front of his house and the other was installed within 310 feet of his house. • Ethics Policy Needed: City lacks explicit ethics rules to prevent committee members from influencing projects for personal gain. 4. Cost Burden and Transparency • High Costs and Uncertainty: According to different estimates, the cost of a traffic circle can range from $10,000–$250,000 per circle; no transparency has been provided by the City. • Maintenance Burden on Residents: Residents/HOA expected to maintain landscaping despite not requesting or supporting these circle installations. 5. Legal Liability to the City • Dangerous Street Obstructions: These devices do not operate as proper traffic circles. • Failure to Adhere to City Procedures: Installation violated explicit RPV traffic calming guidelines/rules, potentially increasing City’s liability in event of accidents. Devices did not meet RPV requirements for installation. • Community Engagement Ignored: Residents most impacted by installations were inadequately consulted or informed. • Formal Notice of Risk: Petition serves as official notice regarding potential City liability for any future injuries that result from the installation of these dangerous devices. In addition to the petition, attached also is a document detailing our many issues with these dangerous traffic devices. Thank you. A-2 A-3 A-4 A-5 A-6 A-7 A-8 A-9 A-10 A-11 A-12 A-13 Remove the Traffic Circles - Page 1 Petition to Remove the Traffic Circles on Avenida Classica We, the residents directly affected by the traffic circles on Avenida Classica at intersections of Avenida Celestial and Avenida Esplendida, respectfully but firmly ask the City of Rancho Palos Verdes to remove these installations and restore safe, familiar, and functional traffic control to our neighborhood. These traffic circles—whether in their current form or modified—have made our streets more dangerous, disrupted traffic flow, and created ongoing maintenance and financial concerns. They are unpopular, unnecessary, and, we believe, implemented without proper community support. We do not want the City to spend any more money on this failed project. We do not want the circles "improved," expanded, or redesigned. We want them removed. To collect views on the traffic circles, a google form was initiated and distributed to people living on Avenida Classica, Avenida Celestial, Avenida Esplendida, and Avenida Selecta. The survey received 53 responses with 50 respondents (94%) seeking the traffic circles’ removal and 3 respondents (6%) expressing a desire for the traffic circles to remain. Based on households, 34 households want the traffic circles removed, and 3 households want to keep the traffic circles. The map on Page 2 shows the distribution of household views, and Page 3 lists the respondents. In collecting support for this petition, various residents provided their reasons for opposing the traffic circles. The pages that follow attempt to summarize those varied views into once document. Residents signing this petition have diverse individual reasons for supporting removal, summarized herein. Not all signatories necessarily agree with every detailed argument presented. While the universal request of all petition signers is the removal of the traffic circles, some respondents believe there are actions necessary beyond removal of the traffic circles. Actions Requested: • Immediate Removal: Eliminate traffic circles at intersections of Avenida Classica/Celestial and Avenida Classica/Esplendida. • Restore Speed Limit Sign: Reinstall missing speed limit sign at logical, visible location and confirm circumstances of its removal. • Full Cost Transparency: Detailed disclosure of all incurred and projected expenses related to the circles. • Commitment to Follow Published Guidelines and Due Process: Ensure meaningful resident involvement and adherence to established City procedures for all future projects. • Adopt Ethics Guidelines: Create and enforce rules preventing the Traffic Safety Committee members from influencing projects involving personal interests.

Cost Burden and Transparency • High Costs and Uncertainty: According to different estimates, the cost of a traffic circle can range from $10,000–$250,000 per circle; no transparency has been provided by the City. • Maintenance Burden on Residents: Residents/HOA expected to maintain landscaping despite not requesting or supporting these circle installations. 5. Legal Liability to the City • Failure to Adhere to City Procedures: Installation violated explicit RPV traffic calming guidelines/rules, potentially increasing City’s liability in event of accidents. Devices did not meet RPV requirements for installation. • Community Engagement Ignored: Residents most impacted by installations were inadequately consulted or informed. • Formal Notice of Risk: Petition serves as official notice regarding potential City liability for any future injuries. A Special Note to the Rancho Palos Verdes Mayor and City Council: You are encouraged to read this letter in full. You are receiving it because the Traffic Safety Committee—acting under delegated authority—is not adhering to the published guidelines posted on its own website. In our neighborhood, this failure has resulted in the installation of two dangerous traffic devices, implemented through actions that significantly exceed the committee’s authorized scope and materially deviated from published guidelines. Guidelines have been set and posted, and they are choosing not to follow them. These actions have compromised public safety and materially increased the City’s liability. This letter outlines the details of one project. If similar overreach has occurred in other committee-endorsed projects, the public’s risk and the City’s legal exposure could be exponentially greater than what is detailed here. Given the controversy and safety risks surrounding these traffic circles, Page 40 presents a ChatGPT-generated example of a legal strategy for a plaintiff’s attorney illustrating how the City could be sued if a hypothetical fatality were to occur, helping the City to better grasp the magnitude of its potential liability exposure. A-18 Remove the Traffic Circles - Page 6 Key Concerns 1. Safety: The Circles Make Our Streets More Dangerous • Cars predominately drive straight through traffic circles without slowing down, yielding, or turning their steering wheels. There is no circular movement necessary around these devices for the vast majority of traffic, which defeats the purpose of a traffic circle. These are not only defective devices, they are dangerous and unwelcomed obstructions in our streets. • Drivers fail to yield. Vehicles on Avenida Classica regularly ignore or do not understand traffic circle right-of-way rules for those who have already entered the circle and force others— especially pedestrians and cyclists and those turning left to or from Avenida Celestial or Esplendida—to stop inside the circle to avoid collision, a serious safety issue that did not exist prior to these unsafe devices being installed. • Visibility is poor. The combination of hedges and a steep slope makes it hard for drivers on Avenida Celestial to see oncoming northbound Avenida Classica traffic. Both circles are also within a few hundred feet of separate blind curves. Avenida Celestial and Avenida Esplendida drivers must inch into the circle before they can safely proceed which places them at risk of T- bone collision from undiverted Avenida Classica traffic driving straight through these defective circles close to the curb. At the same time, Avenida Classic drivers wishing to drive straight through the circle drive closer to the curb and are guiding their cars into sections of Avenida Celestial and Avenida Classica where they have greater risk of hitting pedestrians, cyclists, and cars. Avenida Classica is a wide road; thus, prior to the traffic circles Avenida Classica drivers typically drove closer to the median of the street instead of closer to the curb as they do with the presence of the circles. When Avenida Classica drivers can drive closer to the median with no circles, it is safer for all pedestrians, cyclists, and drivers. • Pedestrians and cyclists are less safe. Residents report it’s harder to cross Avenida Classica safely since the traffic circles were installed. One neighbor who walks the street daily says he’s nearly been hit several times. A tall hedge blocks the only sidewalk between the circles, forcing pedestrians on the side of the street without sidewalks to walk in the street between the circles. They must either cross within the circles—where drivers are focused on navigating the device—or change behavior and cross closer to blind curves that exist on either side of both circles, with little time to be seen and for drivers to react. Traffic now travels closer to the curb to maneuver the circle, putting pedestrians walking on the side of the road without sidewalks at greater risk. Avenida Classica between Los Verdes and Avenida Esplendida does not have a sidewalk on either side of the road which makes crosses after the blind curve and before the circle increasingly dangerous for pedestrians. • Residents face materially higher crash risk. Residents face a higher chance of T-bone collisions when turning onto or off of side streets, compared to the previous two-way stop system. • Controversial and potentially criminal removal of speed limit sign. Google Earth and Apple Maps show a 25 MPH sign at the intersection of Avenida Classica and Avenida Celestial from at A-19 Remove the Traffic Circles - Page 7 least August 2008 to October 2018. It disappeared sometime between October 2018 and July 2023. At a minimum, the City was alerted to the missing sign in public comments by Chris Carbonel at the July 24, 2023 Traffic Safety Committee meeting, yet no replacement has been made. If removed by bad actors to inflate traffic speeds for mandatory traffic studies to justifying extreme and expensive Level 2 measures like traffic circles, this sign removal may be both life- endangering and criminal/unlawful. o City rules1 require Level 2 devices like traffic circles only where the 85th percentile speed exceeds the limit by 7+ MPH. The June 2021 and December 2022 traffic studies2 found 7.0 and 7.5 MPH excess speeds—barely qualifying for consideration of a Level 2 device under City rules. It is very possible the sign was removed prior to these speed tests which would have potentially increased speeds enough to get excess speeds over 7 mph. Even with the questionable speed studies, the project only met 4 of 6 required criteria (FAILED 2 criteria) set by the Public Works Department in the City of Rancho Palos Verdes Neighborhood Traffic Calming Program requirements for Level 2 measures such as traffic circles—further casting doubt on the legitimacy of the installation of these dangerous devices in our community.3 • Wrong-way turns are common. Many drivers, including locals, turn left the wrong way around the circle—suggesting not confusion but preference. Thus, this poor design promotes more traffic violations. The Los Angeles County Sheriff’s Department (LASD) conducted a 2-hour enforcement operation on April 22, 2025, and they observed 3 wrong-way turns in the traffic circle in that short period.4 LASD operations confirm that these devices have brought illegal and unsafe behavior to our neighborhood that did not exist before the traffic circles. • The terrain is a problem. The circle on Avenida Celestial is on a steep slope half way up a hill with large concrete storm channels on either side. The result is a bumpy, awkward, and sometimes unsafe maneuver around the tilted circle. • There is increased flood risk. Further modifications to the Avenida Celestial circle could interfere with drainage or push vehicles toward storm channels, heightening flood or hydroplaning danger during storms. • Many drivers are unfamiliar with traffic circles. Traffic circles are rare in this area, and the nearby golf course brings a steady stream of newcomers to Avenida Classica who are not expecting these circles after the blind curves and often don’t know how to navigate them—leading to confusion, increased crash risk, and reduced neighborhood safety. 1 City of Rancho Palos Verdes Neighborhood Traffic Calming Program “Minimum Threshold for Level 2 Measures”: https://www.rpvca.gov/DocumentCenter/View/94/Traffic-Calming-Guidelines-PDF (page 11-12, 15-31). 2 Traffic Safety Committee Agenda Report by Ramzi Awwad, Public Works Director. https://rpv.granicus.com/DocumentViewer.php?file=rpv_d683c024a0f7b25bc1013b0bd10bcf5a.pdf&view=1 (page 30 of 189) 3 City of Rancho Palos Verdes Neighborhood Traffic Calming Program “Minimum Threshold for Level 2 Measures”: https://www.rpvca.gov/DocumentCenter/View/94/Traffic-Calming-Guidelines-PDF (page 11-12, 15-31). 4 https://rpv.granicus.com/DocumentViewer.php?file=rpv_19d4a7a1801a678affdac7afbd3908e0.pdf&view=1 (page 13 of 39). A-20 Remove the Traffic Circles - Page 8 • Blind curves limit driver reaction time. Although traffic circles become visible about 200 feet in advance, they remain in peripheral vision for much of that visibility range as drivers complete the blind curves. By the time the circles are in full and central view, drivers must quickly adjust—often steering closer to the curb, where pedestrians walk or cross due to lack of sidewalks—greatly increasing the risk of pedestrian fatalities and collisions. • Emergency vehicles may be slowed. In time-sensitive situations, the circles could hinder large first responders’ vehicles like fire trucks trying to navigate these obstructed intersections. This will be made worse by the plan to further widen the circles. • Crash history did not justify installation of dangerous devices in the neighborhood. These dangerous traffic circles introduce new safety risks that are specific to these traffic devices onto a stretch of road that lacks evidence of material safety incident history. The July 2023 KOA Traffic Calming Plan for Avenida Classica included a review of the CWITRS/TIMS crash database, and it found no history of any reported accidents between 2017 to 20225. o Public Work Director Ramzi Awwad indicated in his July 24, 2023 memo to the Traffic Safety Committee that “A review of the state-wide crash database found collisions in the subject area. A more detailed review of City records showed the following result. One crash was recorded for Avenida Classica between Crest Road and Los Verdes Drive during the most recent 5-year period for which data is available (2018 through 2022). That crash occurred on 03-13-2020 and was a vehicle colliding with a fixed object.”6 ▪ Awwad’s comments reference “collisions” (plural) being found in the state-wide crash database, yet KOA’s work cites no accidents in the database they reviewed. Are these the same databases? The comment about a “more detailed review of City records” implies it found one single-car incident that the report references on 3-13- 2020. Why are specifics provided on the incident uncovered via the City record review, but no specifics about number of incidents or specifics on date and factors for the “incidents” in the state databases? How many incidents did Awwad find in the state-wide crash database? What are the facts of those crashes? How should we think about the conflicting information from KOA and Awwad on database reviews? • Speed is not the only dimension of safety. While the City reported a modest 7–9 mph reduction in vehicle speed (from ~32 mph to ~24 mph), the study ignores the far more serious issue of the new traffic risks and violations the traffic circles have proliferated: yield violations, wrong-way driving, near-collisions, and increased risk of accidents for pedestrians, cyclists, and side-street residents have made the streets materially more dangerous. 5 https://rpv.granicus.com/DocumentViewer.php?file=rpv_d683c024a0f7b25bc1013b0bd10bcf5a.pdf&view=1 (pages 60 and 61). 6 https://rpv.granicus.com/DocumentViewer.php?file=rpv_d683c024a0f7b25bc1013b0bd10bcf5a.pdf&view=1 (page 32). A-21 Remove the Traffic Circles - Page 9 3. Deviation from Due Process. The Project May Not Have Followed Proper RPV Required Procedures • The Traffic Safety Committee did not follow proper procedure. At a public Traffic Safety Committee meeting on July 24, 2023, under Chair John Tye, the Committee diverged from Public Works Director Ramzi Awwad’s primary recommendation—road diverters to restrict turns at Avenida Classica & Los Verdes and Avenida Esplendida & Los Verdes, a traffic signal at Hawthorne Boulevard & Los Verdes, and wayfinding signage7. Awwad also provided the Committee with an Alternative Recommendation to consider which was to install traffic circles at 1. Avenida Classica at Los Verdes Drive and 2. Avenida Classica at Avenida Esplendida. Instead, Chair Tye introduced a competing proposal to Awwad’s alternative proposal for committee vote at the end of more than two hours of public comment on Awwad’s primary recommendation. Tye’s competing proposal was seconded by Mark Crossman (current Chair). Tye’s proposal moved one of Awwad’s alternative proposal traffic circles from Avenida Classica and Los Verdes Drive to Avenida Classica and Avenida Celestial. Within a few minutes of Tye making this proposal, the members of the Committee except David Tamblin, who chose to be recognized as absent in his role of committee member and instead act in the capacity of a citizen at this meeting lobbying the committee, unanimously approved Tye’s counter proposal. While dozens spoke for and against Awwad’s primary recommendation featuring diverters on Los Verdes Drive, no public input was sought on Awwad’s alternative recommendation or Tye’s alternative recommendation that was passed. Mailers sent in advance of the meeting to all residents within 500 feet of Avenida Classica referenced a link to an agenda where Awwad’s plan for Los Verdes diverters could be reviewed (see page 24). The traffic circles ultimately approved at that meeting and installed were inconsistent with Awwad’s primary or alternative recommendations that was made available to the public in the agenda ahead of the meeting. This fact pattern is highly problematic for a number of reasons: o A traffic circle is defined by the City of Rancho Palos Verdes as a Level 2 traffic device by rules published by Awwad’s Public Works Department. There are specific criteria that must be met to install a Level 2 traffic device that Public Works Director Awwad and the Traffic Safety Committee did not followed. According to published guidelines of the Public Works Department on the Traffic Safety Committee website in a document called “City of Rancho Palos Verdes Neighborhood Traffic Calming Program: A community leader guide”, multiple requirements were violated with the installation of these traffic circles. The guide outlines “Minimum Thresholds for Level 2 Measures”8 and below is a discussion of how this criterion was not met or was controversially passed. ▪ Controversial Pass: “Streets with a prevailing (85th percentile) speed of 7 mph or more over the posted or designated speed limit” 7 https://rpv.granicus.com/DocumentViewer.php?file=rpv_d683c024a0f7b25bc1013b0bd10bcf5a.pdf&view=1 (page 36) 8 https://www.rpvca.gov/DocumentCenter/View/94/Traffic-Calming-Guidelines-PDF (page 11 and 12) A-22 Remove the Traffic Circles - Page 10 ▪ This criterion is technically met, but a critical speed limit sign was removed from the downhill, southbound section of Avenida Classica that may have been instrumental in the traffic study showing the excess speed reading of 7.5 mph, just 0.5 mph over the minimum threshold. ▪ The City’s first response should have been the Level 1 measure of reinstalling the speed limit sign that was removed. Ideally, the speed limit sign should be installed at the top of Avenida Classica near Crest Rd. rather than half way down the street (the street’s midpoint of 750 feet) on its steep downhill section after a curve. ▪ FAIL: “Streets with an average daily traffic of at least 1,500 vehicles per day or peak hour traffic of at least 150 vehicles per hour.” ▪ The KOA traffic study reported traffic volumes on the street at 1,418 9. This is below the 1,500-vehicle minimum threshold. ▪ FAIL: Level-2 Device Eligibility and Prioritization Formula. The requirements contain a formula where an area is assessed points across 6 factors and must score a minimum total of 51 points to be considered for a Level 2 device such as a traffic circle. As shown on Page 19, the Avenida Classica projects earned a score of only 21 which is materially below the required minimum score of 51 for a Level 2 traffic device. In this case, despite failing this test, this street received two Level 2 traffic circles that this test indicated it was not eligible to have installed. As explained in the guidelines, this scoring system is intended to help the City rank requests in terms of priority given factors such as the large expense involved in installing a Level 2 device. If we look at other streets like Crest and Crenshaw or PV Drive in various sections such as Portuguese Bend or PV Drive N between Crenshaw and PV Drive E where 2 lanes merge down to 1 and traffic is terrible on a daily basis, it is difficult to fathom this project being among the highest priority projects based on this score of 21. ▪ FAIL: Guidelines state that “Level 2 traffic calming measures must be initiated through a petition process. The petition, which is shown on page 33, must have the support of 60% of the property owners on the section of street (or neighborhood) within the limits of the requested traffic calming measures as recommended in the Engineering Study. The limits generally consist of all properties between the first and last device in a series, as well as any property within 200 feet of any device.”10 See page 20 of this letter. ▪ There were petitions that were circulated among residents regarding the traffic diverter plan for Los Verdes Drive as outlined as Director Awwad’s 9 https://rpv.granicus.com/DocumentViewer.php?file=rpv_d683c024a0f7b25bc1013b0bd10bcf5a.pdf&view=1 (page 51 of 189) 10 https://www.rpvca.gov/DocumentCenter/View/94/Traffic -Calming-Guidelines-PDF (Page 5 and 33) A-23 Remove the Traffic Circles - Page 11 primary recommendation. Awwad sent out a letter about his primary recommendation to residents within 500 feet of the projects. ▪ Traffic circles were not initiated through a resident petition process. Traffic circles were a recommendation that came from the KOA report and Awwad. To move forward with a Level 2 device for the area, a petition with 60% support from property owners in the area would have been necessary. Such a petition does not exist for the traffic circles. ▪ RPV’s formal “Level 2 Traffic Calming Petition” includes the following language that must be on the signed petition and in this case explicitly mention the traffic circles. The petitions must explicitly have mentioned “traffic circles” as well as the intersections of Avenida Classica and Avenida Celestial and Avenida Classica and Avenida Esplendida and have the signatures of 60% of the people living within 200 feet of the circles: ▪ Explicit Required Level 2 Traffic Calming Petition Language (page 33)11: “Install (specified traffic calming tool) on (subject street) between (first cross-street) or at (specified location) per the attached conceptual plans dated (month/day/year).” ▪ Whether by mistake or intention, Awwad’s alternative recommendation called for a traffic circle at Avenida Classica and Los Verdes, but the KOA report discussed installation of a circle at the Avenida Classica and Avenida Celestial intersection. The agenda exposed to the public in the letter sent out publicizing the July 24, 2023 meeting to residents within 500 feet of the projects did not indicate that a traffic circle at the intersection of Avenida Celestial and Avenida Classica would be within the range of outcomes that could be adopted at that meeting based on primary and alternative proposals of Awwad and based on the lack of public petition supporting such a project. ▪ FAIL: Awwad stated the following in his memo to the Traffic Safety Committee on July 24, 2023: “Alternatives: In addition to the Staff recommendation, the following alternative actions are available for the Traffic Safety Committee’s consideration: 1. Recommend to the City Council the installation of traffic circles at the intersections of Avenida Classica at Los Verdes Drive and Avenida Classica at Avenida Esplendida; or….” 11 https://www.rpvca.gov/DocumentCenter/View/94/Traffic -Calming-Guidelines-PDF (Page 33) A-24 Remove the Traffic Circles - Page 12 ▪ Under Rancho Palos Verdes guidelines, Alternative 1 was not an option available to the Traffic Safety Committee, and Director Awwad should not have presented it to them as something they had the authority to do. ▪ There was no resident-initiated public petition showing 60% support for the traffic circles. ▪ Traffic circles on Avenida Classica were not permitted due to failure of the minimum traffic volume requirement of 1,500 vehicles and the Level 2 device quantitative score that was 21 and thus substantially below the minimum score of 51 that is required for Level 2 device consideration. ▪ Further, within their range of options, Awwad did not mention that they could take a Level 1 device action and reinstall the speed limit sign that had been removed from the street sometime after October 2018. • See July 24, 2023 meeting from minute 2h 40m - 2h 55m12. Troubling comments from Tye during that section of the meeting: o 2:51:30: Tye: “I don’t want to call it a cop out and I don’t want to call it a halfway measure, but I am trying to resolve an issue without causing more problems for other folks here. So, my suggestion would be as an interim... as an incremental measure would be to use the traffic circles to reduce speeds, use additional signage, investigate other possible mitigation factors while reducing speed before we go… before we go to traffic diverters. ▪ This statement seems to show a fundamental misunderstanding about traffic circles being a serious Level 2 traffic device that has an established and published due process and guidelines that the Traffic Safety Committee and Public Works Director are required to follow. o 2:55:00: Tye: “I know it is contrary to traffic study, and they (City Council) are going to ask for your opinion, and I expect you to give it to them as you gave it to us, I expect no less. But that being said, you know what, let’s roll the dice.” o 2:56:59: Tye: “I’m trying to come up with a viable solution without going all in which will cause other issues. ▪ Gambling references in the context of installation of public safety devices are highly inappropriate, objectionable, and offensive. 12 Chair John Tye deviating from https://rpv.granicus.com/player/clip/4372 A-25 Remove the Traffic Circles - Page 13 3. Conflicts of Interest and Other Controversies • Conflict of Interest and Personal Gain: In 2023, David Tomblin, a Public Safety Committee member living at Avenida Esplendida and Avenida Classica, asked to be marked absent during committee role call at the July 24th meeting and instead lobbied the committee as a resident to support installing traffic devices on his street. o Traffic Safety Committee meeting minutes from July 24, 2023: “MOTION TO ALLOW MEMBER TOMBLIN TO PARTICIPATE AS A RESIDENT: David Tomblin, Committee Member, has requested to be absent from his seat and instead participate as a resident speaking on the item of Avenida Classica.”13 o The resulting outcome of this project is that one traffic circle was installed directly in front of Tomblin’s home and another one was installed within ~310 feet of his property. Note that neighbors have reported that he has since sold his home and moved out of the neighborhood. o Traffic circles cost tens of thousands of dollars to design and construct. This reality in cooperation with safety standards is likely why the City has created extensive guidelines and criteria that must be met to install them. These two traffic circles were installed despite failing these explicit guidelines. o What’s the probability that two top-priority, data-backed safety projects in Rancho Palos Verdes just happen to be within ~300 feet of a Traffic Safety Committee member’s home? The fact that this project scored a 21 on a scale of 100 when a score of 51 was necessary to advance a project goes a long way towards answering that question. o This episode suggests RPV needs an ethics policy to bar committee members from advancing or lobbying for personal projects before committees they serve on. • Was the Traffic Deverter Project proposal for Avenida Classica and Los Verdes Drive really about speed or was it about changing traffic patterns and traffic volume on Avenida Classica? o There is a letter in the July 24, 2023 agenda from Chris Carbonel detailing his conversations with David Tomblin, Dan Myers, and others who promoted the Los Verdes Traffic diverter petition. Carbonel’s first-person accounts raise interesting questions about the motivations behind this project.14 13 https://rpv.granicus.com/DocumentViewer.php?file=rpv_633ab8a07882ff8abcb9ac50310715f0.pdf&view=1 (page 2). 14 https://rpv.granicus.com/DocumentViewer.php?file=rpv_d683c024a0f7b25bc1013b0bd10bcf5a.pdf&view=1 (page 86-99 of 189). A-26 Remove the Traffic Circles - Page 14 4. The Circles Are Costly—and the Burden Falls on Residents • Cost estimates vary widely. The City’s 2008 Traffic Calming Guide lists cost estimates of $10,000–$30,000 per circle. Other cities such as San Diego and engineering firms estimate costs in the range of $90,000–$250,000 each. We believe the public deserves transparency. • We request a full cost breakdown. This should include construction, design, engineering, land acquisition, and maintenance—along with the projected cost if the circles are made permanent and annual upkeep. • HOA responsible for maintenance. The Rancho Palos Verdes Neighborhood Traffic Calming Guide15 regarding traffic circles indicates “landscaping must be maintained by the residents/HOA”. We strongly object to being required to maintain installations we neither requested nor support. 5. These Circles Do Not Fit the Location • These were two-way stops—not the kind of balanced intersections where traffic circles are typically used. • Traffic is extremely uneven. For every 10 cars on Avenida Classica, we estimate that only one enters or exits from Avenida Celestial—leading drivers on the main road to treat the circle as theirs to dominate. Stop signs and stop lines remain in place on Avenida Esplendida further emboldening Avenida Classica traffic in the circle. • These do not operate as traffic circles and that reality cannot be fixed. Avenida Classica is a wide road. The City is limited in its ability to widen these circles from an engineering perspective due to needs of emergency vehicles, and even if widened to maximum permissible amount, traffic will still be able to drive straight through the circles without turning steering wheels. • We believe these may be the first circles in RPV. We object to being a laboratory for confusion and unsafe behavior that puts our families at risk. • Many drivers are unfamiliar with the area. Avenida Classica leads to Los Verdes Golf Course and draws non-resident traffic that cannot be expected to navigate poorly designed and unfamiliar circles safely, especially when they are surrounded by blind curves that reveal them only a few hundred feet in advance. • The circles are unattractive. They detract from the neighborhood’s appearance and property values. Numerous people mentioned that they believe that they impair our property values. 15 https://www.rpvca.gov/DocumentCenter/View/94/Traffic -Calming-Guidelines-PDF (Page 22) A-27 Remove the Traffic Circles - Page 15 6. Questions about the Quality of the KOA Traffic Study • The July 2023 KOA report references the existence of a southbound speed limit sign on Avenida Classica. As previously discussed, this sign does not exist, and was publicly reported as missing on July 24, 2023 at the Traffic Safety Committee meeting, the same month as the KOA report. Does KOA have photos that it took when inspecting these streets where the speed limit sign is visible, or did they rely on outdated maps such as those from Apple Maps that continue to show a picture from 2018 as their latest photo that shows the sign present? Unless KOA has its own photos that show the sign was up during the various speed studies of the road or the City can find confirmation in its records when the City might have removed this sign, the presumption should be that there was no speed limit sign posted during the speed studies used to justify this project. • The KOA report treats safety as a one-dimensional consideration of speed. As discussed in this letter, there are many other dimensions of safety that were either ignored or minimized in the KOA recommendation. Some important considerations: o These traffic circles are defective and cars drive straight through them. o The blind curves on either side of the circles result in difficult visibility issues. o There is no discussion in the circle designs as to where pedestrians are expected to cross the streets. Designs do not accommodate designated pedestrian crossing area. o Most sections of these streets only have a sidewalk on one side of the street and one section immediately before the Avenida Esplendida circle coming out of a blind curve where pedestrians are expected to cross lacks a sidewalk on either side of the street. o Hedge barriers between the traffic circles means that some pedestrians will have no choice but to walk on the street and traffic circles result in cars driving closer to the curb increasing pedestrian danger. o The City of Rancho Palos Verdes has specific guidelines posted that must be met to qualify for a Level 2 traffic device like a traffic circle. The traffic study resulted in this street failing these minimum criteria which made the traffic circles disqualified recommendations that KAO should not have offered. This fact is not acknowledged in the report and compliant alternatives are not offered. o Director Awwad claims he found multiple collisions in a state-wide database, yet the KOA report covering a longer period than Awwad’s review found no incidents. How does KOA explain these inconsistencies? o The study concluded that 4-way stop signs didn't meet required criteria, but it's unclear if it accounted for pedestrian needs, lack of sidewalks, or blind curves. Regardless of KOA’s findings, several residents indicated that they still support 4-way stop signs, citing poor visibility and the danger pedestrians face crossing from the sidewalk-less side. The traffic A-28 Remove the Traffic Circles - Page 16 study seems to minimalize the issue of visibility caused by blind curves and focus purely on a one-dimensional and simplistic definition of safety being equivalent to speed reduction. ▪ In talking with people, many expressed concerns over the blind curves and the limited visibility near the curves. Both traffic circles are situated extremely close to the blind curves. Several thought 4-way stop signs were the best solution because they would provide pedestrians and cyclists the best opportunity for a safe crossing and walking along the street, risk of t-bone collision would be materially lower than with traffic circles, and cars would leave these intersections at slower speeds with a stop sign than they would with traffic circles (especially a circle that requires no turning of steering wheel). ▪ California Vehicle Code section 22450 (c): Regardless of KOA’s finding, one resident pointed out that the City still has the authority to install 4-way stops. ▪ CVC 22450 (c): “Notwithstanding any other provision of law, a local authority may adopt rules and regulations by ordinance or resolution providing for the placement of a stop sign at any location on a highway under its jurisdiction where the stop sign would enhance traffic safety.” 7. The City Should Be Held Accountable if Someone Is Injured by These Circles • The City’s formal requirements for installation of these traffic circles were not followed. The Traffic Safety Committee and Public Works Director deviated from RPV requirements making these illegal and dangerous road obstructions that could result in critical or fatal injuries. • The City’s duty is to do no harm. These circles have harmed our neighborhood—physically, financially, and civically. They should be removed before someone is seriously or critically injured and irreversible damage is done. • There was a lack of community engagement. The people most affected by this project were not properly consulted or involved. We provided feedback on a project from the City Public Works Director that the Traffic Safety Committee rejected and proposed their own. • This petition serves as formal notice. If an accident, injury, or fatality occurs at these intersections, the record will show that residents raised serious safety concerns in advance including their lack of operation as traffic circles and the legality of these circles’ existence since RPV formal process was not followed. A-29 Remove the Traffic Circles - Page 17 What We’re Asking For • Immediate removal of the traffic circles on Avenida Classica at Avenida Celestial and Avenida Esplendida. • Repost the southbound speed limit sign on Avenida Classica. If speed is truly an issue on this street, re-install the speed limit sign that went missing years ago under mysterious circumstances. Ideally, it would make sense to have the speed limit sign posted at the beginning of the street by Crest rather than the midpoint (750 foot mark) of the street. We would also like confirmation from the City as to whether the City removed this speed limit sign, whether it has knowledge of how it came to be removed, or its removal was a criminal act. • Full disclosure of all costs incurred and projected. • A renewed commitment to meaningful public engagement and proper following of City procedures on future projects. Traffic Safety Committee guidelines have been in place since 2008, and it is our expectation that members of the committee and the City follow these published guidelines. • Adopt ethics requirements that bar committee members from directly or indirectly bringing projects to the committee during their tenure to avoid perception or reality of self-dealing. • Consider having Traffic Safety Committee members and members of the Public Works Department sign annual ethics statements and acknowledgements that they have read and are committed to following the “City of Rancho Palos Verdes Neighborhood Traffic Calming Program: A community leader guide” which provides guidelines for how this program is to operate.

Rather, they are illustrating that: 1. These devices do not function as proper traffic circles since drivers on Avenida Classica drive straight through the “circles” without a need to turn their steering wheels. These are simply dangerous obstacles inserted in the road. 2. The circles result in the drivers driving significantly closer to the curbs than in the past since the “circles” forcing them further from the street’s median. 3. Circles pushing cars towards the curbs makes for dangerous situations for pedestrians, cycles, and drivers coming in and out of side streets of Avenida Celestial and Avenida Esplendida. 4. These circles have been dangerously inserted on steep hills. 5. Circles are only visible for ~200 feet and most of that distance is in side peripheral view of the driver instead of in the middle of their field of vision.

ChatGPT Asked to Act as a Plaintiff’s Lawyer in the Hypothetical Situation that Someone is Severely Injured or Killed as a Result of the Traffic Circle. ChatGPT was asked to outline a legal strategy in the event of injury or death caused by the traffic circles. This hypothetical is presented to help the City recognize how the circles’ safety issues, procedural violations, and ethical concerns collectively create significant legal liability. 1. Establishing City Liability: The Core Legal Theory I would pursue the claim under California Government Code § 835 (Dangerous Condition of Public Property). To prevail, we must show: • A dangerous condition existed on public property; • The condition proximately caused the decedent’s death; • The dangerous condition created a foreseeable risk of death/injury; • The City had actual or constructive notice of the dangerous condition and failed to remedy it. The fact pattern of in this letter helps establish every element. How the Petition Strengthens the Case A. Foreseeability & Actual Notice • The letter was submitted to the City before the fatality, creating a contemporaneous public record of known safety hazards. • It cites multiple categories of foreseeable harm: T-bone collisions, yield violations, wrong-way driving, poor visibility, obstructed pedestrian paths, and possible speed manipulation through the removal of speed limit signage. B. City-Created Risk • The City affirmatively created the dangerous condition by deviating from its own safety guidelines, installing the circles improperly, and failing to correct known hazards. • These dangerous traffic circles would not have existed if City published guidelines were followed. The circles were never initiated through the required public petition, failed the threshold point scoring system (21 vs. required 51), and violated procedural safeguards necessary for installation of Level 2 devices. • The City had formal notice of a removed speed limit sign on July 24, 2023 or earlier, and the sign remains unposted as of July 29, 2025. A-53 Remove the Traffic Circles - Page 41 C. Violation of Statutory Duties / Administrative Rules • The Traffic Safety Committee violated its own Neighborhood Traffic Calming Program (NTCP) guidelines first published in 2008 and maintained on their website as of the current date (7.29.2025) and presented to the public as their current guidelines. • The City failed to follow due process, providing no opportunity for public comment on the proposal ultimately adopted and the 60%-support petition requirement was ignored. • The City ignored the failed criteria for Level 2 devices and the mysterious removal of the speed limit sign may have resulted in fabricated legal justification through flawed or manipulated data. D. Conflict of Interest = Gross Negligence • The proximity of a committee member’s home to the devices, combined with procedural irregularities and his active lobbying of the committee to pass a proposal, suggests self-dealing or bias, which elevates the negligence from passive oversight to gross negligence.

In October 2024, temporary traffic circles (consisting of striping and bollards) were installed at the following intersections: • Avenida Classica at Ave Celestial • Avenida Classica at Ave Esplendida This memo presents the results of a study comparing traffic speeds on Avenida Classica at the same point, before and after the installation. An aerial view of the study area, before the installation, is shown in Exhibit 1. 1. Background Avenida Classica is a 0.3-mile-long residential street between Crest Road and Los Verdes Drive in the City of Rancho Palos Verdes (RPV). The posted speed limit is 25 mph. The street has two pronounced curves, one with a radius of 220 feet and one with a radius of 150 feet. The terrain is sloping, with an elevation gain of 85 feet between Los Verdes Drive and Crest Road. Prior to the traffic circle installation, the intersection of Avenida Classica and Ave Esplendida was two-way STOP controlled with STOP signs at the Ave Esplendida approaches. The intersection of Avenida Classica and Ave Celestial had no intersection controls. In April 2023, KOA Corporation completed a Traffic Calming Plan for Avenida Classica recommending the installation of traffic circles and providing a concept design. GTS completed the final design for the traffic circles in May 2024. GTS has also carried out other studies in the area, including a memo presenting recommendations for filling a sidewalk gap on Avenida Classica directly south of Ave Esplendida (January 2023) and a memo evaluating the need for a marked crosswalk across Avenida Classica at the intersection with Ave Esplendida. Speeds were measured for the KOA study, before the traffic circle installation, in June 2021 and December 2022. Speeds were measured again, after the traffic circle installation, in March 2025. E-1 2 Exhibit 1. Study area aerial image before circle installation (source: NearMap) E-2 3 2. Speed Surveys Speed data collection took place at the same location (shown in Exhibit 2, utilizing the same utility pole for anchoring, and employing the same type of equipment (pneumatic tubes positioned across the street) and logging the same parameters (traffic volumes and speeds) in June 2021 (before traffic circle installation) and in November 2024 and March 2025 (after traffic circle installation). In each case, speed data was collected in 15-minute increments over a 48-hour period. The data collection in June 2021, November 2024, and March 2025 was done by the same company in each case (AimTD). Exhibit 2. Location of speed data collection (map provided by AimTD) Speed data collection also took place in December 2022 (before circle installation), but this used a different technology (roadside radar counters). The 85th-percentile speed is used in the traffic engineering industry as a reference to establish speed limits based on the concept that most motorists can be relied upon to drive at a reasonable speed. Studies have shown that setting arbitrarily low speed limits results in wholesale violations and does not necessarily result in lower driving speeds. The California Vehicle Code (CVC), Section 627, refers to the 85th percentile speed, as described above, as essentially representing the speed considered safe and reasonable for setting speed limits on roadways, with certain modifications based on the application of the judgement of a Traffic Engineer due to specific site conditions. The results of the speed surveys are summarized as follows: • June 22, 2021 (before traffic circle installation): The 85th-percentile speed was 32 mph (30 mph eastbound and 32 mph westbound). The AM average speed (12:00 AM – 12:00 PM) was 25 mph. The PM average speed (12:00 PM – 12:00 AM) was 25 mph. E-3 4 • June 23, 2021 (before traffic circle installation): The 85th-percentile speed was 31 mph (30 mph eastbound and 34 mph westbound). The AM average speed (12:00 AM – 12:00 PM) was 27 mph. The PM average speed (12:00 PM – 12:00 AM) was 26 mph. • December 2022 (before traffic circle installation): The 85th-percentile speed was 32.5 mph. The available data from this survey does not include an eastbound/westbound breakdown or an overall average speed. Therefore, the data from this survey is not included in the comparison, but it is described here for the sake of completeness. • November 12, 2024 (after traffic circle installation): The 85th-percentile speed was 27 mph (25 mph eastbound and 27 mph westbound). The AM average speed (12:00 AM – 12:00 PM) was 22 mph. The PM average speed (12:00 PM – 12:00 AM) was 21 mph. • November 13, 2024 (after traffic circle installation): The 85th-percentile speed was 28 mph (25 mph eastbound and 27 mph westbound). The AM average speed (12:00 AM – 12:00 PM) was 22 mph. The PM average speed (12:00 PM – 12:00 AM) was 22 mph. • March 25, 2025 (after traffic circle installation): The 85th-percentile speed was 24 mph (23 mph eastbound and 24 mph westbound). The AM average speed (12:00 AM – 12:00 PM) was 19 mph. The PM average speed (12:00 PM – 12:00 AM) was 19 mph. • March 26, 2025 (after traffic circle installation): The 85th-percentile speed was 24 mph (22 mph eastbound and 25 mph westbound). The AM average speed (12:00 AM – 12:00 PM) was 19 mph. The PM average speed (12:00 PM – 12:00 AM) was 19 mph. Exhibit 3 provides a high-level overview of the findings in terms of the 85th-percentile speed, derived from the combined eastbound and westbound directions and the combined days of each data collection effort. Overall, comparing speeds before and after traffic circle installation, a reduction in the 85th-percentile speed ranging from 7 mph to 9 mph is observed. Exhibit 3. Combined 85th-percentile speed for each data collection period Exhibit 4 shows the 85th-percentile speed, broken down by direction, AM/PM, and day, for each data collection period. Overall, AM and PM speeds are similar, westbound speeds tend to be higher than eastbound speeds due to the westbound direction leading downhill, and a reduction in 85th-percentile speed ranging between 4 mph and 9 mph can be observed from the pre-installation data to the post-installation 32 32.5 25 23 0 5 10 15 20 25 30 35 June 2021 December 2022 November 2024 March 2025 85th-percentile Speed (Eastbound and Westbound Combined) E-4 5 data. A reduction in speed is also observable between the November 2024 data and the March 2025 data, suggesting that speeds have decreased more after the traffic circles have been in place for longer. Exhibit 5 shows the average speed, also broken down by direction, AM/PM, and day, for each data collection period. Again, AM and PM speeds are similar, westbound speeds are higher, and average speeds decreased by between 3 mph and 8 mph from the pre-installation data to the post-installation data. Similarly to the 85th-percentile data, the average speed data shows a slight further reduction between November 2024 and March 2025.

Emergency Vehicle Testing The Los Angeles County Fire Department visited the traffic circles in March 2025, navigating the two intersections with a standard-size fire engine. They concluded that the traffic circles could be navigated successfully and did not create a problem for emergency response. 4. Traffic Enforcement Operations The Los Angeles County Sheriff’s Department (LASD) conducted an enforcement operation in the study area on April 22, 2025 from 4:00 pm to 6:00 pm. The patrol car location is shown in Exhibit 6. The timeframe was selected based on a request from a neighborhood resident, who noted that this period typically sees the highest traffic volume on the weekday due to activity at the nearby golf course. Exhibit 6. Patrol car location (map provided by LASD) LASD was stationed at the location indicated on Avenida Classica to monitor vehicle speeds coming from both Crest Road (southbound) and Los Verdes Drive (northbound). Using a handheld LiDAR speed gun, which can measure vehicle speeds at a distance of up to 1,500 feet, LASD recorded vehicle speeds on Avenida Classica approximately 500 feet south of Crest Road and between 50 and 100 feet north of Los Verdes Drive. During the two-hour period, around 200 vehicles were observed, with only one vehicle reaching a maximum speed of 30 mph. All other vehicles were traveling well below the 25 mph limit. LASD also observed three instances of drivers on Avenida Classica making improper left turns onto Avenida Celestial (going the wrong way on part of the traffic circle): 1) A solid waste collection truck going southbound 2) A visitor unfamiliar with the area going northbound 3) A resident going southbound No citations were issued, only verbal warnings. E-7 8 From a public safety perspective, LASD currently does not see speeding as a primary issue in this area, especially with the traffic circles in place. However, both LASD and City public safety staff observed a visibility concern at the intersection of Avenida Classica and Ave Esplendida. There were numerous pedestrians crossing during the enforcement period, and visibility is limited due to the curve from Los Verdes Drive onto Avenida Classica. There were a few instances where vehicles needed to stop at the traffic circle to allow pedestrians to finish crossing. City public safety staff noted that the absence of a stop sign and or marked crosswalk raises safety concerns in what appears to be a highly walkable neighborhood. 5. Sight Distance Analysis Per the California Highway Design Manual, 7th Edition (Table 201.1), the stopping sight distance at 25 mph is 150 feet. GTS conducted a site visit in December 2024 and measured the sight distances along Avenida Classica at the intersection with Ave Esplendida. While the sight distance is adequate for the southbound approach, there is sight distance limitation for the northbound approach for a vehicle pulled forward to the curb line, as shown in Exhibit 7. If no parked vehicles are present along Avenida Classica, the sight distance of 150 feet (at 25mph) is currently achieved. However, if parked vehicles are present, the sight distance is obstructed. It should be noted that pedestrians mostly cross at the east approach of the intersection as there are no sidewalks on the west approach. Exhibit 8 shows the view along northbound Avenida Classica approaching the Ave Esplendida intersection. If cars are parked in the visible area that is currently not red-curbed, the view can be obstructed, as shown in Exhibit 9. Exhibit 7. Sight triangles for a vehicle approaching Avenida Classica on Ave Esplendida, showing 150-ft sight distance E-8 9 Exhibit 8. Sight distance on northbound Avenida Classica (150-foot distance) approaching Ave Esplendida Exhibit 9. The same view as in the previous exhibit, with a parked car blocking the view E-9 10 6. Conclusions and Recommendations A significant reduction in speed has been observed since the traffic circles were installed. This is observable both in the 85th-percentile speed and in the average speed, during the AM and PM periods and in both the eastbound and the westbound directions. For an accurate comparison, it was ensured that the “after” data (November 2024 and March 2025) was collected in the same location, using the same methods, as the “before” data (June 2021). The most recent data (March 2025) shows an 85th-percentile speed that is close to the posted speed limit, and an average speed that is well below the speed limit. It can be concluded that the desired traffic calming effect has been achieved. Periodic monitoring of speeds should be continued to assess the effect over the long term. Although speeds have been reduced, the following actions could still be taken for added safety: Short-term: 1. Daylight the intersection of Avenida Classica and Ave Esplendida by red-curbing the northbound approach for an additional 30 feet beyond the existing red curb, making a total of about 75 feet from the intersection, as shown in Exhibit 11. 2. Add a Pedestrian Ahead sign at the start of the red curb (W11-2 sign and AHEAD) to notify uphill vehicles of pedestrians crossing. 3. Roundabout directional arrow (R6-4 series) signs and/or ONE WAY (R6-1R or R6-2R) signs are also recommended signs to indicate the travel direction within a roundabout. 4. To further discourage errant left turns, in addition to the larger traffic circle described in item 5, the City could modify the striping along Avenida Classica to enhance the entry to the roundabout in terms of splitter island, entry lane widths, and entry deflection angles. Although this is typically done for a more permanent installation such as concrete or Vortex type roundabout, this can also be done for the existing tactical implementation. 5. The existing 20-foot diameter of the traffic circle at the intersection of Avenida Classica and Ave Esplendida could be increased to a 20-foot diameter curbed inner circle plus a 1-foot all around mountable radius, resulting in a 20 + 2 = 22-foot new widened diameter. 6. The City could install a traffic circle made of readily available materials per the specifications described in item 5 above. An example of such an installation is shown in Exhibit 10. E-10 11 Exhibit 10. Example of a temporary traffic circle (Encinitas, CA) Long-term: 7. The City could install a more robust, permanent traffic circle according to the specifications of item 5 above. 8. The City could close the sidewalk gap on Avenida Classica south of Ave Esplendida, as outlined in the Feb. 2023 GTS memo. E-11 12 Exhibit 11.

Executive Summary CITY OF RANCHO PALOS VERDES-TRAFFIC CALMING PLANS | AVENIDA CLASSICA PAGE 1 1.0 EXECUTIVE SUMMARY 1.1 SUMMARY OF FINDINGS In response to concerns raised by residents of Avenida Classica in the City of Rancho Palos Verdes, KOA Corporation (KOA) was retained by the City (RPV) to perform an analysis of the existing traffic conditions on Avenida Classica and nearby impacted areas, to determine whether the concerns support further consideration of implementing traffic calming measures. The sections following describe the various data collection, engineering analyses, local community outreach, and subsequent technical recommendations resulting from this traffic calming study effort. "Traffic Calming" is an aspect of community traffic management that focuses on implementing physical roadway measures to alter driver behaviors determined to be negatively affecting the livability and safety of residents and other non-motorized road users. Traffic calming uses physical design and other measures to improve safety for motorists, pedestrians, and cyclists. Traffic calming involves a uniform process that identifies the need for, and develops and installs as justified, approved traffic control devices and horizontal/vertical measures targeted at reducing specific concerns, such as excessive traffic speeding, cut- through traffic volumes, and/or other unsafe or undesired traffic movements and driver behaviors. Representatives of the City of RPV and KOA organized an in-person meeting with residents of Avenida Classica to collect feedback, confirm the perceived concerns, and incorporate input and observations into the development of traffic calming strategies for the street. Relevant traffic data collected by KOA was organized and analyzed to establish a baseline understanding of residents’ concerns, and to identify traffic factors such as existing average daily traffic (ADT) volume levels, vehicle speeds, and the nature and extent of traffic collisions. Through extensive study it was determined that the neighborhood concerns about speeding, cut-through traffic and erratic driving were valid and reasonable to justify the consideration of significant traffic calming measures, primarily aimed at reducing vehicle speeds and diverting golf course-related traffic away from Avenida Classica. F-5 Executive Summary CITY OF RANCHO PALOS VERDES-TRAFFIC CALMING PLANS | AVENIDA CLASSICA PAGE 2 1.2 AVENIDA CLASSICA – TRAFFIC CALMING NEEDS AND GOALS Avenida Classica is a 1,580-foot long, two-lane local street serving local residents in the westerly part of Rancho Palos Verdes, just west of the intersection of Hawthorne Boulevard and Crest Road near the Los Verdes Golf Course. Avenida Classica is bound by Crest Road to the north and Los Verdes Drive to the south. See Figure 1.1 for a map of the study area. The goals of this study are as follows: · Identify and analyze ongoing traffic concerns within the neighborhood, based on an assessment of measured vehicle volumes, speeds, field observations, and resident input and feedback; · Recommend traffic calming countermeasures to mitigate the traffic concerns to appropriate levels that are consistent with the City’s goals, policies and standards for residential communities in Rancho Palos Verdes; and · Minimize any potential adverse impacts of the recommended traffic calming recommendations on: o Other adjacent streets and neighborhoods o Emergency vehicle response times; o Pedestrians, bicyclists and other non-motorized road users · Prepare a Traffic Calming Plan for Avenida Classica documenting the existing conditions, data collection, engineering analysis, community outreach, and conceptual plans and cost estimates to implement the recommended traffic calming countermeasures. Through community engagement efforts, residents of Avenida Classica voiced their concerns to the City and KOA about their experienced and perceived traffic and safety issues occurring on the street. After conducting a detailed analysis and series of discussions with City staff and the affected residents, the following conceptual improvements were developed: Implement traffic calming measures to reduce daily travel speeds on Avenida Classica to speeds closer to that of the currently established speed limit. o Install diagonal diverters at the southerly ends of Avenida Classica and Avenue Esplendida, at Los Verdes Drive, to prevent the use of the streets as cut-through routes to and from the Los Verdes Golf Course. o In the case that diverter improvements are not supported or approved, consider the installation of two (2) raised traffic circles on Avenida Classica at Avenue Esplendida and Avenue Celestial. Install additional wayfinding guide signage at strategic points along the Hawthorne/Los Verdes access route to and from the golf course. This measure will help to direct and inform golf course visitors as to the correct available route to reach the golf course. Install a traffic signal at the intersection of Hawthorne Boulevard and Los Verdes Drive. The traffic analysis indicates that a signal is warranted during the four-hour and peak-hour periods, and would benefit the potential increase in traffic volumes resulting from the abovementioned traffic calming improvements. Note: the recommendation for traffic signal installation presumes that the abovementioned traffic calming diverters would be concurrently installed, as the resulting traffic diversions to the intersection of Los Verdes Drive and Hawthorne Boulevard support the satisfaction of the traffic signal warrant. F-6 Executive Summary CITY OF RANCHO PALOS VERDES-TRAFFIC CALMING PLANS | AVENIDA CLASSICA PAGE 3 FIGURE 1.1 – STUDY AREA Los Verdes Golf Course F-7 Existing Conditions and Data Collection CITY OF RANCHO PALOS VERDES-TRAFFIC CALMING PLANS | AVENIDA CLASSICA PAGE 4 2.0 EXISTING CONDITIONS AND DATA COLLECTION Avenida Classica is a 40-foot wide, two-lane undivided local street serving local residents, with direct access to Crest Road on the north (uphill end of the street), and Los Verdes Drive to the south (downhill end). The posted speed limit on Avenida Classica is 25 miles per hour, and on-street parking is permitted on both sides except during street sweeping hours between 7:30AM and 4:30PM during the first and third Thursday of the month. The physical roadway alignment of Avenida Classica is characterized by significant horizontal and vertical changes over its quarter-mile span, having two horizontal curves (R=195’ and R=250’, approximately) separated by a 350-foot tangent section, as well as a vertical grade change ranging between 0 and 22 percent, for an average of about 7 percent on the street. Figure 2.2 illustrates the elevation profile of the roadway with respect to the intersecting cross streets (i.e., Avenue Celestial and Avenue Esplendida) within the study area. To understand the existing conditions for the various traffic characteristics that comprise this evaluation, KOA collected data at select locations based on comments received from the community during June 22, 2021, Traffic Safety Committee meeting and other correspondences with the City. The following data was collected as part of this traffic study. 2.1 TRAFFIC VOLUMES Initial traffic volume data was collected on a Tuesday (June 22nd) in 2021. 24-hour Average Daily Traffic (ADT) volume counts were collected using fixed roadway machine/tube counters placed across the street. These devices register two-way vehicle traffic driving through a selected point on the traveled way. Two- way traffic counts were taken on Avenida Classica at approximately mid-segment between Celestial and Esplendida. Intersection turning movement counts were also collected in 2021 at two intersections along Avenida Classica, at (1) Avenue Esplendida and (2) Los Verdes Drive. Additional traffic volume counts were collected in late 2022/early 2023 as part of an expanded analysis to identify potential traffic impacts and contingent strategies related to the implementation of the recommended traffic calming measures on Avenida Classica. 2.2 SPEED COUNT DATA To determine whether potential speeding issues exist on Avenida Classica in accordance with resident concerns, 24-hour traffic speed counts were collected concurrently with the ADT volume counts on Avenida Classica, on Tuesday, June 22nd, 2021; Wednesday, June 23rd, 2021; and during the 2022 holiday period from Monday, December 19th through Sunday, December 25th. Figure 2.1 illustrates the study locations of the ADT count and speed measurements.

The following points encompass the purpose of the outreach meeting: · Inform residents of the status of the project study, and open up the discussion to input · Seek to refine the scope of work of the study based on resident input · Discuss potentially available traffic calming options, and gauge residents’ general level of support for certain ideas · Provide a follow-up plan based on the results of the meeting A variety of discussion topics were covered during the meeting. Various ideas, issues and suggestions were raised by the residents, as summarized below. Los Verdes Golf Course F-9 Existing Conditions and Data Collection CITY OF RANCHO PALOS VERDES-TRAFFIC CALMING PLANS | AVENIDA CLASSICA PAGE 6 Issues · Speeding – Residents raised concerns over aggressive and fast-driving motorists at various times of the day on Avenida Classica, likely those driving to and from the nearby Los Verdes Golf Course · Driver Safety – Residents reported a number of traffic collisions on the street, resulting from erratic driving and/or inattention to the roadway and roadside conditions within the neighborhood context. Various collisions and “close-calls” were reported between aggressive/speeding drivers and other cars driving on Avenida Classica, parked cars along the street, and drivers backing out and heading into driveways. · Pedestrian Safety – Residents expressed concerns about speeding motorists not safely yielding to and/or navigating around pedestrians crossing the street · Blind Curves – Concerns were raised about the traffic safety due to visibility conflicts between motorists traveling along the horizontal curves, and motorists both approaching in the opposite direction on the street and backing out of residential driveways. Ideas and Suggestions · Enforcement – Deploy additional enforcement to monitor speed and provide immediate relief. · Speed Humps – Under the right conditions, and when designed properly, speed humps may be effective at attenuating speeding behavior; however, standard practice is to obtain a general consensus on their use, and it is currently not known whether the community would support their implementation. · Stop Signs – As stated in Sections 2B.04 and 2B.05 of the CAMUTCD, and as a common industry practice, stop signs are not a “cure-all” or substitute for other, more appropriate traffic control devices, and should not be used as a means to address speed control issues. Stop signs are intended to regulate right-of-way at conflicts between roadways and turning maneuvers, and so KOA will investigate whether the two existing mid-segment intersections (presently only two-way stop controlled) are warranted to consider the implementation of all-way stop controls. · Traffic Signals – Due to the local neighborhood setting, signalized traffic control devices will not be appropriate for Avenida Classica. KOA nevertheless plans to investigate whether a traffic signal at the nearby intersection of Los Verdes and Hawthorne Boulevard is warranted, due to its location and proximity to the study area as a critical entry point into and out of the Los Verdes neighborhood. · Traffic Circles – The implementation of neighborhood traffic circles in similar local street settings has demonstrated high effectiveness in reducing speeds, compared to other low-cost measures. KOA will evaluate whether the physical roadway and intersection conditions on Avenida Classica can accommodate viable traffic circle features. · Turning Movement Restrictions and/or Street Closure – Residents expressed an interest in restricting turning movements into and out of Avenida Classica at the south end of the street, in order to minimize cut-through traffic through the neighborhood. KOA will evaluate potential options for traffic diversion strategies and investigate the potential impacts of such measures. · Lighted Crosswalks – One resident’s suggestion put forth during the meeting was to install “lighted crosswalk”, which typically involves the implementation of high-visibility marked crosswalks along with illuminating features such as street lights, rectangular rapid-flashing beacons, and/or in-roadway warning lights.

ADT data can help estimate the overall level of traffic regularly experienced on a given roadway segment, as well as identify particular periods throughout the day when traffic volumes demonstrate rising or falling fluctuation patterns. While ADTs do not depict the exact origins and destinations of those cars which it measures, ADT does reveal a sense of the daily “busyness” of a street as traveled by cars, and the directional distribution of traffic throughout the day. ADT counts on Avenida Classica were collected on two typical, consecutive weekdays in June 2021. Figure 3.1 illustrates the 48-hour average daily traffic volume in each direction, and for the two directions combined. Figure 3.2 shows the two-day average roadway volumes during the AM hours (i.e., midnight to noon), while Figure 3.3 shows the two-day average roadway volumes during the PM hours (noon to midnight). The two-day average 24-hour traffic volume on Avenida Classica was 1,418 vehicles per day, including 472 vehicles (33%) during the AM hours per day and 946 vehicles (67%) during the PM hours per day. On the average day, 53% of traffic on Avenida Classica was in the southbound direction, while 47% of traffic was in the northbound direction.

The speed survey data was used to identify the prevailing speeds traveled by motorists on a typical day. Speed survey locations were chosen based on reviewing the existing conditions and selecting a mid- block point where the influence of traffic controls and turning traffic would be minimized and would sufficiently represent free-flow travel speeds on the street. According to the California Vehicle Code (CVC), the prima facie, or “default” speed limit on residential streets is 25 miles per hour, unless otherwise posted. There are currently 25-MPH (Type R2-1) speed limit signs posted on Avenida Classica north of Los Verdes Drive in the northbound direction, and north of Avenue Celestial in the southbound direction. The average (50th percentile) speed recorded on Avenida Classica in June 2021 was greater than the posted speed limit, measured at 27 mph during the AM and 26 mph during the PM hours. The 85th percentile speed, or critical speed, generally represents the upper limit of the speed range that most reasonable and prudent motorists will drive. For a typical residential street, an 85th percentile speed reported above 25 miles per hour may indicate either a) a potential speeding concern, in which measures should be implemented to reduce vehicle speeds; or b) an evident need to accept a higher posted speed limit in order to better serve the needs of motorists. The two-day, bi-directional average 85th percentile speed recorded on Avenida Classica in June 2021 was 32 mph, which is 7 mph in excess of the posted speed limit. Table 3.1 summarizes the two-day traffic speed data for the street, in each direction as well as for the combined directions of travel during the June 2021 survey period. KOA performed a follow-up speed survey in late December 2022 using roadside radar counters, to re- evaluate travel speeds during the typical holiday season when schools were not in session. The findings of the follow-up speed survey were comparable to the June 2021 survey. Over the 5-day survey period from Monday 12/19 to Sunday 12/25, the average daily two-way 85th percentile speed was 32.5 mph, which is 7.5 mph above the posted speed limit. Table 3.2 summarizes the five-day traffic speed data during the December 2022 survey period.

Due to the potential increase in traffic volumes entering Hawthorne Boulevard from Los Verdes Drive, resulting from the implementation of certain traffic calming measures on Avenida Classica, it was determined that sight distance should be evaluated at this location to identify any potential safety concerns. Motorists departing from the Los Verdes Golf Course originally destined to proceed north on Avenida Classica, may likely divert to the intersection at Los Verdes Drive and Hawthorne, where they will be required to turn left across the free-flowing traffic lanes onto northbound Hawthorne Boulevard. The avoidance of collisions and negotiation of right-of-way between vehicles on conflicting travel paths depends in part on the judgement, capabilities, and response of the individual drivers. However, it is important for a driver approaching the potential intersecting path of another vehicle to have an unobstructed view of the entire intersection ahead (including at driveways), and within a reasonable amount of time, in order to control the operation of their vehicle and avoid striking motorists within the traveled way. This includes providing sufficient view of traffic control devices, and sufficient lengths along the intersecting street to permit drivers to anticipate and avoid potential collisions with one another. The sight distance needed in each situation is directly related to approaching vehicle speed, roadway and lane geometry, and the distance available to traverse during the perception-reaction-braking time period. Specified areas along intersection approach legs and across their included corners should ideally be clear of obstructions that might block a drivers’ view of potentially conflicting vehicles. These “corner sight triangle” areas are determined by calculating triangular geometries that account for observed driver behavior and documented speed choice of drivers on the intersection approach. By providing unobstructed corner sight areas, if a vehicle stopped on the minor street sees that the intersecting roadway is clear and leaves its stopping point to either cross or enter the major street, oncoming vehicles in either direction will have sufficient time to negotiate the entering vehicle and prevent collision. The recommended geometry of the corner sight triangles, based on the American Association of State Highway and Transportation Officials’ (AASHTO) latest A Policy on Geometric Design of Highways and Streets (shown below as Table 3.2) varies with the type of traffic control at the intersection and prevailing vehicle speeds. Table 3.3 indicates various sight distance adjustment factors based on the vertical grade of the primary street. It is important to note that these values are not required to be met as a uniform standard, and therefore non-satisfaction of AASHTO sight distance recommendations does not necessarily indicate improper roadway design. In reality, drivers will often self-mitigate low sight distance conditions by encroaching slightly beyond the stop line before entering the intersecting roadway to gain a better vision of oncoming traffic. However, it is strongly recommended that as a conservative measure, the subject intersections should account for the AASHTO minimum sight distance to minimize the potential for adverse vehicle conflicts. Based on this analysis, KOA noted that the corner sight distance between drivers waiting from a stopped position on Los Verdes Drive and drivers approaching north and south on Hawthorne Boulevard is less than the recommended minimum AASHTO calculated sight distance. The primary factor causing the limited sight is the high approach speed of traffic on Hawthorne Boulevard, coupled with vertical grade constraints and boundary wall obstructions behind the westerly sidewalk. Figure 3.4A shows the ISD analysis diagram for Hawthorne Boulevard at Los Verdes Drive. F-18 Analysis CITY OF RANCHO PALOS VERDES-TRAFFIC CALMING PLANS | AVENIDA CLASSICA PAGE 15 TABLE 3.2 – MINIMUM RECOMMENDED SIGHT DISTANCE BASED ON VEHICLE MANEUVER TABLE 3.3 - ADJUSTMENT FACTORS FOR SIGHT DISTANCE BASED ON APPROACH GRADE It is important to note that adequate sight distance issues may be improved, or potentially corrected, by drivers who are waiting at the stop line, by pulling forward slightly beyond the stop bar provided that they do so without encroaching into the opposing traveled way. Figure 3.4B (second inset) illustrates the improved sight distance conditions for drivers waiting to exit onto Hawthorne Boulevard by "creeping" forward to a point of visibility. As illustrated in Figure 3.4B, with drivers on the Los Verdes Drive approach creeping past the limit line to view opposing traffic, the available left- and right-turn sight distance improves in each direction; however, the minimum recommended adequate sight distance is still not available.

Eight-hour vehicular, pedestrians and bicycle traffic volume count data was collected from 6AM to 9AM, 11AM to 1PM, and 4PM to 7PM for all four legs of the intersections, on Tuesday, Jun 22nd, 2021. 3.3.1 ALL-WAY STOP WARRANT ANALYSIS: AVE ESPLENDIDA AND AVENIDA CLASSICA This intersection is an unsignalized four-leg, two-way stop controlled intersection between Avenue Esplendida (stop-controlled direction) and Avenida Classica. Avenida Classica is the major roadway, with one lane in each direction, and Ave Esplendida is the minor street with one lane in each direction. There were no posted speed limits found on Avenue Esplendida; therefore, it follows that the prima facie limit on Avenue Esplendida is 25 mph. The posted speed limit on Avenida Classica is 25 mph. There are no horizontal or vertical curvatures observed on either roadway. On-street parking is generally allowed on both roadways. Figure 3.5 shows the AM and PM peak hour vehicle turning movement at the intersection. FIGURE 3.5 - AM/PM PEAK HOUR VEHICLE TURNING MOVEMENTS AT AVENUE ESPLENDIDA AND AVENIDA CLASSICA F-21 Analysis CITY OF RANCHO PALOS VERDES-TRAFFIC CALMING PLANS | AVENIDA CLASSICA PAGE 18 The multi-way stop sign warrant analysis was conducted based on Chapter 2B- Regulatory Signs, Barricades and Gates- Section 2B.07 Multiway STOP Application, of the California Manual on Uniform Traffic Control Devices (CAMUTCD), 2014 Edition Revision 6. The CAMUTCD identifies various factors that may be utilized in considering the need for additional stop controls, such as vehicular volumes, traffic collisions, pedestrian activity, traffic speeds and other physical and operational characteristics of the subject location. These criteria are organized into various “warrants” in the CAMUTCD. Using the available traffic data, KOA conducted an analysis to determine if the installation of a multi-way stop is warranted under the present conditions. The warrant study includes a review of daily and hourly vehicle traffic volumes and peak-period pedestrian and bicycle volumes. The following is a summary of the findings for the CAMUTCD stop sign warrant analysis: A: Not Met Temporary Traffic Control. There are currently no plans in place to install a traffic signal at this location in the immediate future; therefore, the installation of a multi-way stop at this intersection would not serve to provide any urgent or desired safety benefits to control traffic during the preparation or consideration of such signalized controls. B: Not Met Crash Problem. From 2017 to 2022, there were no accidents reported in the SWITRS/TIMS database. Therefore, this warrant criterion is not met. C: Not Met Minimum Traffic Volumes. A stop sign installation may be considered where major and minor street traffic volumes meet minimum values and conditions designated in the CAMUTCD. As shown in the traffic counts data, the intersection of Avenue Esplendida and Avenida Classica exhibit a relatively low degree of traffic volumes which do not exceed the minimum thresholds; therefore, this warrant criterion is not met. D: Not Met 80% of Minimum Volumes. Where none of the above criteria are satisfied, but where the Crash Problem and Minimum Traffic Volumes warrants are both satisfied to 80 percent of the minimum values, a stop sign installation may be considered. As shown in traffic data, the eight-hour traffic volumes do not exceed the minimum 80% threshold; therefore, this warrant criterion is not met. Based on the above multi-way stop control warrant evaluation, the subject intersection is presently not warranted for the consideration of an all-way STOP. 3.3.2 ALL-WAY STOP WARRANT ANALYSIS: AVENIDA CLASSICA AND LOS VERDES DRIVE This intersection is an unsignalized T-intersection where Avenida Classica terminates from the north at Los Verdes Drive, which runs east/west. Los Verdes Drive is the major road at this intersection, with one lane in each direction, while Avenida Classica is the minor street with one lane in each direction. The prima facie speed limit on Los Verdes Drive is 25 mph, and the posted speed limit on Avenida Classica is 25 mph. Avenida Classica intersects perpendicularly with a horizontally curved portion of Los Verdes Drive. On-street parking is permitted on both roadways except during days and hours of street sweeping activities. Figure 3.6 shows the AM and PM peak hour vehicle turning movement at the intersection.

There are currently no plans in place to install a traffic signal at this location in the immediate future; therefore, the installation of a multi-way stop at this intersection would not serve to provide any urgent or desired safety benefits to control traffic during the preparation or consideration of such signalized controls. B: Not Met Crash Problem. From 2017 to 2022, there were no accidents reported in the SWITRS/TIMS database. Therefore, this warrant criterion is not met. C: Not Met Minimum Traffic Volumes. A stop sign installation may be considered where major and minor street traffic volumes meet minimum values and conditions designated in the CAMUTCD. As shown in the traffic counts data, the intersection traffic volumes at Los Verdes Drive and Avenida Classica do not exceed the minimum thresholds; therefore, this warrant criterion is not met. D: Not Met F-23 Analysis CITY OF RANCHO PALOS VERDES-TRAFFIC CALMING PLANS | AVENIDA CLASSICA PAGE 20 80% of Minimum Volumes. Where none of the above criteria are satisfied, but where the Crash Problem and Minimum Traffic Volumes warrants are both satisfied to 80 percent of the minimum values, a stop sign installation may be considered. As shown in Appendix, the eight-hour traffic volumes do not exceed the minimum 80% threshold; therefore, this warrant criterion is not met. Based on the above multi-way stop control warrant evaluation, the subject intersection is presently not warranted for the use of an all-way STOP. 3.5 SPEED HUMPS ANALYSIS Speed humps are designed to reduce vehicle speed and improve road safety in residential areas. Speed humps are areas of pavement raised 2-3 inches in height over a length of typically 12-22 feet across the roadway. The main objective of the speed humps is to reduce the speed of traffic and make the road safer for pedestrians, cyclists, and motorist. As per the City of RPV’s ‘Neighborhood Traffic Calming Program1, there are some general conditions and requirements which must be fulfilled to consider the installation of speed humps along Avenida Classica. The City’s guidelines also include the following key geometric constraints and conditions to consider when evaluating the feasibility of installing speed humps: (1) Speed humps are typically not used on street profiles where the grade exceeds 8%; (2) The installation of speed humps should also not be considered on streets greater than 40 feet wide, or with volumes exceeding 3,000 vehicles per day; and (3) Speed humps are also not recommended on horizontal curves of less than 300 feet centerline radius, and vertical curves with less than the minimum safe stopping sight distance1. Note that the abovementioned maximum street grade threshold of 8% is intended to limit the turbulence on vehicles crossing over speed humps while simultaneously negotiating a steep grade. Since the street grade of Avenida Classica is 9%, this maximum criterion is not satisfied. The horizontal curvature minimum is also unmet for either curve since the centerline radii of these curves are less than 300 feet (i.e., R=195’ for the southerly curve, and R=245’ for the northerly curve). Based on this analysis, the criteria to consider installing speed humps on Avenida Classica is not sufficiently satisfied. 3.6 MARKED CROSSWALK AND LIGHTED CROSSWALK Crosswalks in general are designated areas where pedestrians are given the right-of-way and where drivers are expected to stop for pedestrians crossing the street. A marked crosswalk is a type of pedestrian crossing that is delineated by painted lines, signs, and/or other markings on the road, while a lighted crosswalk is a type of pedestrian crossing that is illuminated or has lighting to make it more visible to drivers and pedestrians. Marked crosswalks are usually found at major intersections and are intended to extend the travel path of pedestrians from one roadside to the other. The purpose of marked crosswalks is to provide a safe and visible area for pedestrians to cross the street and to increase driver awareness of pedestrian crossings. Based on the analysis and safety considerations, the installation of crosswalks across Avenida Classica are not required, nor recommended. This takes into account a number of variables, including pedestrian volume, and vehicle speeds, absence or discontinuity of sidewalks and curb ramps, driver expectations, pedestrian activity, the presence of other pedestrian crossings in the area, and general suitability for the local neighborhood context. While there is no single prescribed “warrant” to determine the eligibility of a location to install a marked crosswalk, in KOA’s experience, for the few local agencies that develop their 1 ‘Neighborhood Traffic Calming Program’, City of Rancho Palos Verdes, December 2008 F-24 Analysis CITY OF RANCHO PALOS VERDES-TRAFFIC CALMING PLANS | AVENIDA CLASSICA PAGE 21 own guidelines, a minimum threshold of 20 pedestrian crossings during the peak hour is typically used, to determine whether a marked crosswalk should be considered. Peak-hour pedestrian crossing volumes on Avenida Classica were counted as 9 during the AM hour and 7 during the PM peak hour. Similar to the marked crosswalk case, there exists no official “warrant” criterion for crosswalk illumination. Some local agencies have established soft thresholds such as 50 or 100 pedestrian crossings at night. The CA MUTCD also prescribes a 40 pedestrian/hour criterion for in-roadway warning lights. Given the low pedestrian volumes at the study intersection, Avenida Classica does not meet the minimum requirements and conditions to consider installing a marked crosswalk and/or crosswalk lighting features. 3.7 SOUTHBOUND RIGHT-TURN DIVERTER AT LOS VERDES DRIVE Diagonal diverters are islands built diagonally across a street or intersection which prevent certain turning traffic movements. In order to reduce cut-through traffic on Los Verdes Drive, a diagonal diverter could be installed at the south end of the street, which would to prevent golf course-related traffic from using Avenida Classica to travel in and out of the neighborhood to access the golf course. A diverter would force southbound right-turning vehicles to make a left onto Los Verdes Drive, and northbound left-turning vehicles to continue straight on Los Verdes Drive. A similar design would be useful to implement at Los Verdes Drive and Avenue Esplendida, as well, in order to prevent diverted traffic from attempting to use Esplendida as a secondary cut-through route. The main goal of this measure would be the redirect golf course-related traffic away from Avenida Classica and instead enter/exit the neighborhood by using the intersection of Hawthorne Boulevard at Los Verdes Drive. 3.8 TRAFFIC SIGNAL AT HAWTHORNE BOULEVARD AND LOS VERDES DRIVE Due to the potential for diverted traffic (identified in Section 3.7 above) to increase traffic volumes at the existing unsignalized intersection of Hawthorne Boulevard and Los Verdes Drive, a traffic signal warrant analysis was conducted to determine if there would be a newly-generated need to install traffic signal controls at the affected intersection. The traffic signal warrant analysis was prepared in accordance with Chapter 4C- Traffic Control Signal Needs Studies, of the CAMUTCD. The warrant study included a review of eight-hour, four-hour and peak-hour vehicle traffic volumes, and pedestrian volumes. Hawthorne Boulevard is considered the major roadway, with a curb-to-curb width of 80 feet and posted speed of 45 mph. Los Verdes Drive is considered the minor roadway with a curb-to-curb width of 40 feet and prima facie speed limit of 25 mph. The signal warrant reflects existing traffic conditions based on volume data collected on a typical Friday in 2023. The analysis also considers the addition of diverted traffic due to the implementation of diagonal diverter traffic calming measures mentioned above in Section 3.7. The latest data was collected on March 17, 2023, from 7:00-9:00 AM, 11:00-1:00 MD, and 2:00-6:00 PM. There are total of nine possible signal warrants, three of which are applicable to the study intersection: WARRANT 1- EIGHT HOUR VEHICLE VOLUME This warrant is intended for scenarios where the volume of intersecting traffic is the principal reason for considering a signal installation. It also applies to operating conditions where traffic volume on a major street is so heavy that traffic on the minor intersecting street encounters an excessive delay or hazardous conditions while entering or crossing the major street. The major street approach volumes along Hawthorne Boulevard and the minor street approach volumes along Los Verdes Drive were evaluated based on the 24- hour traffic counts. As shown in Figure below, CAMUTCD Warrant #1 (Eight Hour Vehicular Volume) was met. The eight-hour traffic volumes on the higher approach of the minor street do not meet the requirement of 150 (at 100%) or 120 (at 80%) vehicles per hour for minimum vehicle volume conditions. The interruption of continuous traffic conditions is not met based on the minimum of 75 (at 100%) or 60 (at 80%) vehicles on the higher approach of the minor street. F-25 Analysis CITY OF RANCHO PALOS VERDES-TRAFFIC CALMING PLANS | AVENIDA CLASSICA PAGE 22 The combined volume of both approaches on Hawthorne Boulevard and the higher volume on Los Verdes Drive does not meet the required volumes in Warrant 1. Therefore, the study intersection does not satisfy Warrant 1. WARRANT 2- FOUR HOUR VEHICLE VOLUME This warrant is intended to determine if minor street traffic suffers undue delay in entering or crossing the major street in the four highest hours of the day. Warrant 2 requires that all the plotted points fall above the curve in Figure 4C-1 of the CAMUTCD. As shown in the Figure below, all four traffic volume plot points for the four hours meet the minimum conditions. Therefore, the intersection meets the four-hour volume warrant to consider the installation of a traffic signal. F-26 Analysis CITY OF RANCHO PALOS VERDES-TRAFFIC CALMING PLANS | AVENIDA CLASSICA PAGE 23 WARRANT 3- PEAK HOUR VEHICLE VOLUME This warrant determines if, for one hour of the day, minor street traffic suffers undue delay in entering or crossing the major street. Based on the traffic volumes collected, the peak-hour volumes along Hawthorne Boulevard were 2,035 vehicles in the morning and 1,944 in the evening; the highest volumes on the minor street approach were 119 in the AM peak hour and 145 in the PM peak hour. Based on the volume criteria for this warrant, as illustrated in the figure below (indicated by the plotted red triangle points for the AM and PM peak hour volumes on the major and minor streets) the minimum requirement is satisfied to consider the installation of a traffic signal. F-27 Analysis CITY OF RANCHO PALOS VERDES-TRAFFIC CALMING PLANS | AVENIDA CLASSICA PAGE 24 3.9 TRAFFIC CIRCLE / ISLAND Traffic circles require drivers to slow down to a speed that allows them to comfortably maneuver around them. Traffic circles can improve safety by forcing speeding traffic to conform to lower speeds designated for the roadway, without requiring vehicles to fully stop, and can also improve pedestrian safety by reducing the number of conflict points between pedestrians and vehicles. Traffic circles created by constructing a raised island placed at the center of the intersection. They may be landscaped with ground cover and/or street trees. The primary purpose of traffic circles is to slow traffic while providing right-of-way control at intersections. Traffic circles are most effective when constructed in a series on a local service street; however, they can be difficult for large vehicles to negotiate and must be carefully designed to ensure that pedestrian and emergency vehicle mobility is not compromised. Based on the traffic analysis of the study area, there are two locations identified where a traffic circle may feasibly be implemented: (1) Avenida Classica at Ave Celestial, with a circle diameter of 26 feet; and (2) Avenida Classica at Avenue Esplendida with a circle diameter of 25 feet. The two traffic circle locations would be spaced 300 feet away from each other, and would serve to physically attenuate traffic speeds, particularly along the central “straight-head” segment on Avenida Classica between Esplendida and Celestial. 3.10 WAYFINDING SIGNAGE In the case that Avenida Classica is altered with traffic calming measures to prevent its use as a viable route to and from the Los Verdes Golf Course, installing wayfinding signage in the surrounding area can be an F-28 Analysis CITY OF RANCHO PALOS VERDES-TRAFFIC CALMING PLANS | AVENIDA CLASSICA PAGE 25 effective solution to help visitors to find the appropriate entrance and exit routes. Wayfinding signage is designed to help drivers navigate the physical environment, reach their destination, and locate convenient routes to return to the external street network, by providing clear and concise information about where to go and what to expect. In order to most efficiently direct drivers away from Avenida Classica and to the golf course entrance, the wayfinding signage should be strategically placed in areas where people are likely to look for information. This might include on Los Verdes Drive along the main roadway leading to the golf course, the golf course parking lot, and other key locations along Los Verdes Drive and Hawthorne Boulevard. Additional wayfinding signs may be placed at the entry points to Avenida Classica indicating where access to the golf course is not available. It is important to note that in the interest of serving the local aesthetic context of the neighborhood, all wayfinding signage should be designed to be visually appealing and easy to read, with clear and concise messages that convey the necessary information. This might include directional arrows, maps, or other graphics that help visitors understand where to go. The signage should also be consistent with City and County standards and requirements, in terms of design and messaging to help create a cohesive and unified visual identity for both the golf course and City. In the study area, there are three primary locations that put new wayfinding signage to guide visitors about the main entrance of the golf course. (1) Southbound Hawthorne Boulevard at Crest Road: Install one Los Verdes Golf Course location sign which guides visitors to proceed straight (i.e., south on Hawthorne Boulevard, rather than right to Avenida Classica) to reach their destination. CAMUTCD signs G200-80(CA), G200-81A(CA) and M6-3 are viable sign combination options for this purpose. (2) Avenida Classica and Los Verdes Drive: In conjunction with the installation of right-turn diverters at Los Verdes/Esplendida and Los Verdes/Classica, turn restriction signage should be installed to restrict access to and from the golf course along Avenida Classica and Avenue Esplendida. (3) Los Verdes Drive and Hawthorne Boulevard: Similar to sign combination (1) above, a similar sign combination would be installed at key points along the inbound route from Hawthorne Boulevard to Los Verdes Drive, including at the northwest corner of the intersection at Hawthorne/Los Verdes. This intersection would serve as the primary neighborhood entrance and exit for the Los Verdes Golf Course. As per the sample graphic below, or as depicted on CAMUTCD Figure 2D-18, this intersection would be an ideal candidate location for a new golf course entrance wayfinding sign. FIGURE 3.7 – RECOMMENDED WAYFINDING AND TRAFFIC SIGNAGE F-29 Conclusion and Recommendations CITY OF RANCHO PALOS VERDES-TRAFFIC CALMING PLANS | AVENIDA CLASSICA PAGE 26 4.0 CONCLUSION AND RECOMMENDATIONS 4.1 RECOMMENDED TRAFFIC CALMING MEASURES Based on the various traffic analyses described in Section 3, it is recommended that traffic calming measures be explored and undertaken to address the identified issues. The three primary concerns for targeting are as follows: (1) The existing daily 85th percentile speed is around 32-33 miles per hour, which is greater than 5 miles per hour above the existing speed limit (25 miles per hour) of the roadway. Implementation of physical traffic calming measures would benefit road users and adjacent residents by serving to reduce daily travel speeds on Avenida Classica to lower speeds that more closer match the currently established speed limit of the street. (2) Diagonal diverter traffic calming devices, installed at the intersections of Los Verdes/Classica and Los Verdes/Esplendida, are recommended for consideration. These features would physically restrict golf course-related traffic movements from accessing Avenida Classica and Avenue Esplendida as cut- through routes. (3) In the case that diagonal diverters are not advocated for, or otherwise not permitted, by the local residents or City officials, traffic circles would provide another viable option to improve traffic safety on Avenida Classica. Implementation of traffic circles would not preclude drivers from using Avenida Classica as a route to access the golf course; however, the circles would expectedly reduce speeding and erratic driving maneuvers on the street at all times of the day. (4) In order to better inform and direct golf course-related traffic away from sensitive local streets in the neighborhood, particularly Avenida Classica and Avenue Esplendida, it is recommended that additional wayfinding signage be installed in the vicinity of the study area. As shown in the previous section, the wayfinding sign system would include golf course signs on Hawthorne Boulevard and Los Verdes Drive informing motorists to utilize this alternate ingress and egress route. (5) Based on the traffic signal warrant analysis, the intersection of Hawthorne Boulevard and Los Verdes Drive is warrant for consideration of traffic signalization. The traffic signal installation is contingent on the concurrent assumption that the proposed traffic calming diverters will be installed, since they would result in traffic diversions to the intersection of Los Verdes Drive and Hawthorne that support the satisfaction of the traffic signal warrant.
