Liu, Public Works Director/City Engineer SUBJECT: NTMP Hawkwood - Stop Signs & Pavement Legends Recommendations RECOMMENDATION: Concur with the installation of two (2) stop signs and associated legend markings at the intersections of Hawkwood Road and Chirping Sparrow Road and Ambusher Street, as the final phase of the NTMP. BACKGROUND/DISCUSSION: In response to ongoing neighborhood concerns regarding speeding along Hawkwood Road, the Public Works Department implemented a multi -phase Neighborhood Traffic Management Program (NTMP) to improve safety and calm traffic. The Traffic and Transportation Commission has been kept informed and engaged throughout the development and implementation of the program since its inception. Phase 1 of the program, completed in 2023, involved roadway striping enhancements followed by a post-implementation monitoring period to evaluate effectiveness. Based on the observed conditions, staff determined that additional traffic calming measures were necessary, prompting the initiation of Phase 2. Phase 2 was completed in June 2025 and included the installation of three (3) strategically placed speed cushions between Bent Twig Lane and Falcon Ridge Road. Additional improvements included double yellow centerlines, edge line striping, and CITY OF DIAMOND BAR ~ 21810 COPLEY DRIVE ~ DIAMOND BAR, CA 91765 ~ TEL. (909) 839-7040 ~ FAX (909) 861-3117 5.1 Packet Pg. 54 associated signage. A speed study conducted following implementation found the 85th percentile speeds to range between 25 and 28 MPH, which is generally considered acceptable for residential streets and consistent with industry standards. In addition to concerns about speeding, residents also raised issues related to vehicles failing to yield at the T-intersections of Hawkwood Road at Chirping Sparrow Road and Ambusher Street. In response, staff proactively evaluated the conditions and is recommending the installation of two (2) stop signs and associated legend striping at these intersections. These improvements are proposed as Phase 3, the final phase of the Hawkwood Road NTMP. Refer to the attached plan and technical memorandum for additional details. Attachments: 1.

The study area consists of the segment of Hawkwood Road between the existing terminus south of Falcon Ridge Road and Bent Twig Lane to the north. Midblock centerline striping and three sets of speed cushions were installed throughout the study area in late 2024. The following analysis evaluated vehicle speeds along various segments of the roadway before and after implementation. KeyFindings The study area is separated into four study segments, where speed data was evaluated over seven consecutive days in the years 2022, 2023, and 2025 (Table 1) 1. South of Falcon Ridge Road 2. Between Falcon Ridge Road and Chirping Sparrow Road 3. Between Ambushers Street and Barbi Lane 4. North of Barbi Lane Improvements installed throughout the study area consisted of the following: 2023 Double yellow centerline striping on approach to intersections, edge lines, and speed limit pavement legends. 5.1.b Packet Pg. 57 Attachment: Fehr Peers Memo - Hawkwood Road NTMP Phase 3 Stop Signs and Pavement Legends (NTMP Hawkwood - Stop Signs & Chris Malpica, City of Diamond Bar May 9, 2025 Page 2 of 3 2024 Speed cushions, double yellow centerline midblock, and pavement legends for speed cushions.

Treatments implemented in 2024 were more effective at reducing vehicle speeds (compared to those in 2023), and especially within segments 1 and 2 south of Chirping Sparrow Road. All observed 85th percentile speeds are within 5 mph of the posted speed limit (25 mph), which is in alignment with speed-setting standards1. Where speed cushions were implemented in 2024 (segments 2 and 4), observed vehicle speeds decreased to the posted speed limit, demonstrating the effectiveness of implemented measures. While immediate actions to address excessive travels speeds is not necessary, the City may continue to monitor studied locations and consider additional speed management measures if observed 85th percentile speeds increase. Recommendations To support neighborhood traffic calming efforts along Hawkwood Road, the installation of side street stop control is recommended at the intersections with Chirping Sparrow Road and Ambushers Street. Hawkwood functions as a neighborhood collector with horizontal curves and grade changes throughout and has recently undergone calming treatments as described earlier in 1 Per the California Manual on Uniform Traffic Control Devices (CA-MUTCD), an 85th percentile speed that is within 5 mph of the posted speed limit aligns with established speed-setting guidance outlined in Section 2B.13. A 5-mph rounding tolerance is commonly applied when determining posted speed limits, and deviations within this range are not typically considered grounds for speed related intervention. As such, although the observed 85th percentile speed exceeds the posted limit of 25 mph in certain segments, it remains within acceptable thresholds. 5.1.b Packet Pg. 58 Attachment: Fehr Peers Memo - Hawkwood Road NTMP Phase 3 Stop Signs and Pavement Legends (NTMP Hawkwood - Stop Signs & Chris Malpica, City of Diamond Bar May 9, 2025 Page 3 of 3 this study. Although effective speed reductions were observed, the uncontrolled intersections can be improved by installing stop control to more efficiently assign right-of-way. Under the California MUTCD (Sections 2B.04 and 2B.06), stop signs are warranted on minor approaches when the volume or functional classification difference between roads makes the standard right-of-way rule2 insufficient to ensure safe operation, or where sight distance is limited. Hawkwood carries higher traffic volumes and serves as a through route, while both Ambushers Street and Chirping Sparrow Road terminate as they intersect with Hawkwood Road. Assigning right-of-way via stop signs will clarify intersection control and enhance safety. The California Vehicle Code defaults to right-hand or prior-entry yielding at uncontrolled intersections, and at an uncontrolled T intersection the traffic on the through road (Hawkwood) has the right-of-way, and drivers on the terminating side streets must yield to cross traffic on Hawkwood. However, without regulatory signs, this right-of-way rule relies solely on driver judgment and sight distance, which can be compromised by Hawkwoods curves and grades. While stop signs should not be used for speed control, their use here aligns with traffic calming goals by reinforcing safe entry behavior at conflict points. Stop control on Chirping Sparrow Road and Ambushers Street is thus justified and recommended as part of a broader, systemically applied safety strategy. 2 https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=VEH&sectionNum=21800. 5.1.b Packet Pg. 59 Attachment: Fehr Peers Memo - Hawkwood Road NTMP Phase 3 Stop Signs and Pavement Legends (NTMP Hawkwood - Stop Signs &
