MONTHLY UPDATES OF VARIOUS PROJECTS/PROGRAMS: 1. Adaptive Traffic Control Signal System (ATCS) – AE/Malpica - Staff continues to monitor the ATCS performance and has made minor technical system adjustments to accommodate field changes. 2. Professional On-Call Traffic and Transportation Engineering Services – AE/Malpica - Request for Proposals (RFP) Contracts were awarded to Kimley Horn Associates, Iteris Inc. and Fehr & Peers at the June 15th City Council meeting for on-call traffic and transportation engineering services. Each contract is for a duration of three (3) years, beginning July 1, 2021 and continuing through 2024. Retaining three (3) consultants enables the City to efficiently solicit the required th ree (3) quotes, per the City’s Purchasing Ordinance, prior to awarding work for certain public projects. The scope of services includes traffic design, traffic impact analysis, traffic and adaptive system support, transportation system planning, congestion management support, traffic signal operation and coordination, funding and grant support, public meetings support, and other traffic-related services. 3. Caltrans Pavement Rehabilitation Project/State Route 57 Freeway – AE/Malpica - Caltrans and the City entered into a Cooperative Agreement in 2020 under which Caltrans will display and maintain detours in the City as part of the rehabilitation project along the SR-57 between the Orange/LA County lines to the SR-60. The overall project scope is for pavement replacement with concrete slabs in both directions of SR-57, which will enhance ride quality and maximize the service of the roadway. The High-Occupancy Vehicle (HOV) Lanes on SR-57 have been closed since April 2021 to allow for the first phase of the project. Extended weekend closures are scheduled to begin in Stage 2 of the project. Closures have not been scheduled. Staff 1.A.a Packet Pg. 7 Attachment: T&T Commission Meeting Minutes - July 8, 2021 (T&T Commission Meeting Minutes of July 8, 2021) JULY 8, 2021 PAGE 3 T&T COMMISSION continues to work closely with the agency and will update the Commission accordingly. 4. Grand Avenue/Golden Springs Drive Intersection Improvements – AE/Malpica - This project is underway as scheduled with 35% completion as of today. A 90-day settlement period for the slopes (inside the golf course) at the southeast of the intersection will begin mid-July 2021 for preparation of the new relocated tunnel (north of Golden Springs Drive). Traffic delays are anticipated for the next couple of months during the installation of the new decorative traffic signal poles, roadway paving, striping, streetscape improvements installation of pre-cast architectural features, and architectural lighting. Staff will continue to work closely with the contractor to minimize delays at this intersection and will keep the L.A. County Sheriff’s Department, Fire Station 120, and the public informed of potenti al delays. 5. NTMP/Featherwood Drive Neighborhood – Neighborhood Traffic Management Program – AE/Malpica - A resident requested to address speeding concerns along Featherwood Drive, between Looking Glass Drive and Sylvan Glen Road. In response to the request, staff mailed out 135 notification letters to the residents on all affected streets and provided them with the opportunity to express their support for an NTMP in the area via an online survey petition launched in June 2021. Meanwhile, speed and volume counts were collected and are currently under review. To move forward with the NTMP process, the survey responses are required to obtain at least 51% support for the NTMP. The online survey responses were due by June 25, 2021, and only 13 responses (4 opposed) were received by the due date. This led to about 9.6% support for the process, which is significantly lower than the required 51% per the program guidelines ; therefore, staff will work with the resident to consider other options to mitigate traffic concerns along Featherwood Drive. AE/Malpica responded to C/Busteed that the typical survey response rate is 13 to 14 percent. 6. NTMP/Hawkwood Drive Neighborhood Traffic Management Program – AE/Aoun – 200 NTMP survey letters were mailed to the Hawkwood Drive neighborhood residents. The letter contains a link to an online survey where residents can petition to either include or exclude their neighborhood from the NTMP. To date, staf f has received over 30 responses, heavily in favor of being included in the NTMP. This neighborhood will be split into two (2) separate sub - neighborhoods labeled as Area 1 and Area 2. Area 1 includes all homes on Hawkwood Drive, while Area 2 includes all homes on Falcon Ridge Road and the connected cul-de-sacs. The sub-areas serve to 1.A.a Packet Pg. 8 Attachment: T&T Commission Meeting Minutes - July 8, 2021 (T&T Commission Meeting Minutes of July 8, 2021) JULY 8, 2021 PAGE 4 T&T COMMISSION better separate any proposed traffic calming mitigations and allow residents to have a greater influence on their street’s NTMP process. 7. NTMP/Del Sol Lane Neighborhood – Neighborhood Traffic Management Program – AE/Aoun - A Traffic Engineering Consultant was selected to prepare a traffic calming plan for the neighborhood. The plan will be presented at a second NTMP neighborhood meeting where the residents will have the opportunity to share their thou ghts and concerns on the proposed measures. The contract will be awarded at the beginning of the new fiscal year, which began July 1, 2021. Staff will update the Commission at a future meeting regarding the second NTMP meeting date for this neighborhood. 8. Diamond Bar Boulevard Rehabilitation (Mountain Laurel Way to Pathfinder Road) - AE/Aoun - Construction of the project began in late May and is scheduled to be completed by mid-August. The contractor has completed all concrete improvements, including ADA curb ramps, curb and gutter, and sidewalk replacement. Pavement grinding began on Friday, June 24, 2021, at Mountain Laurel Way and is scheduled to continue until Thursday, July 1, 2021, with paving and striping commencing subsequently. A minimum of one lane will remain open in each direction at all times. Staff is continuously inspecting the project and monitoring traffic conditions along the boulevard. Once complete, the project will have rehabilitated approximately one mile of Diamond Bar Boulevard and enhanced the bike lane striping along the corridor. 9. Citywide Speed Zone Survey Extension – AE/Aoun - Pursuant to CVC 40802, jurisdictions are required to have a valid Speed Zone Survey in order for officers to enforce the posted speed limits on public streets. The Survey involves gathering speed and volume data on public roadways, excluding residential streets. The data is analyzed by a registered professional engineer and submitted as a comprehensive study that recommends the posted speed limits in the City. The Study is valid for 5 years and can be extended to 7 years if the citing officers have the proper training and the electronic speed measuring devices have the proper certifications. The validation can subsequently be extended to 10 years if a registered engineer determines no significant changes in roadway or traffic conditions have occurred. The City of Diamond Bar last performed a Citywide Speed Zone Survey in 2014 on 39 roadway segments. The Survey validation was extended to 2021 in 2019. The City solicited the services of Kimley Horn Assoc., a professional engineering firm that has served the City as an on -call traffic engineering consultant, to study the roadway conditions for another extension. The study recommended the City extend the validity of the Survey to 10 years, expiring June 9, 2024. A copy of the recommendation was forwarded to the L.A County Sheriff’s Department Walnut/Diamond Bar and is posted on the City’s website. 1.A.a Packet Pg. 9 Attachment: T&T Commission Meeting Minutes - July 8, 2021 (T&T Commission Meeting Minutes of July 8, 2021) JULY 8, 2021 PAGE 5 T&T COMMISSION 10.

Local Roadway Safety Plan (LRSP) – AE/Malpica - The LRSP report was completed in accordance with the Federal regulation that requires each State to prepare and implement a Strategic Highway Safety Plan (SHSP). Cities can implement an LRSP to address local safety needs while also contributing to the success of the SHSP. Grant funding is available through the Highway Safety Improvement Program (HSIP), administered by the California Department of Transportation (Caltrans), for local LRSP projects. Grant applications for the next HSIP Cycle 11 are expected to open by April of 2022. Preparation of Diamond Bar’s LRSP was made possible with a $72,000 Caltrans grant, matched by $8,000 in City funds for an overall project cost of $80,000 total.

Adaptive Traffic Control System (ATCS) Staff continues to monitor the ATCS performance and continues to make field adjustments to address unforeseen challenges. B. Audible Pedestrian Signal and Pedestrian Pushbuttons New Audible Pedestrian Signal (APS) crosswalk buttons , also known as audible crossing indicators, were installed at the intersection of Golden Springs Drive and Diamond Bar Boulevard. This is in response to a request from a visually impaired resident who uses this intersection to travel from home to the nearby outdoor shopping center. These upgraded APS are American with Disability Act (ADA) compliant as they communicate information about the WALK and DON’T WALK intervals at signalized intersections in non-visual formats (i.e., audible tone and vibrotactile surface) to pedestrians who are visually impaired or have low vision. This unit also announces which street you are going to cross and the countdown of h ow long you have to cross. The “touchless” activation is a great feature o f this new APS. By simply waving a hand over the button, the flashing light indicates that the button has been activated. CITY OF DIAMOND BAR ~ 21810 COPLEY DRIVE ~ DIAMOND BAR, CA 91765 ~ TEL.

Caltrans Pavement Rehabilitation Project/State Route 57 Freeway Long-term closure of northbound SR-57 Brea Canyon Road on-ramp was performed on July 28, 2021, as part of the project to remove and replace concrete slabs in both directions of SR-57. This will enhance ride quality and maximize the service of the roadway. Caltrans released a notification to all agencies located in the vicinity of the freeway advising of the anticipated noise, vibrations, and dust associated with construction activities. Detours through the City of Diamond Bar have not been scheduled, as of yet; however, staff continues to work closely with the agency and will update the Commissio n accordingly. D. Grand Avenue/Golden Springs Drive Intersection Improvements This project is underway as scheduled, with 45% completion as of September 3, 2021. A 90-day settlement period for the slopes (inside the golf course), at the southwest corner of the intersection, is in its 7th week. This settlement phase will prepare the foundation for the new relocated tunnel (west of Golden Springs Drive) connecting the northern and southern portions of the golf course. Installation of the decorative traffic signal poles, along with streetscape improvements, has been partially completed. Retaining walls construction in the golf course parking lot is currently underway, which will be followed by the ground preparation for the construction of the new dedicated southbound right turn lane on Golden Springs Drive onto westbound Grand Avenue. The work of all electrical, remaining streetscape, pre-cast architectural features, and architectural lighting will continue for the next couple of months. Staff will continue to work closely with the contractor to minimize delay s at this intersection and keep the Sheriff’s Department, Fire Station #120, and the public informed of potential delays. E. NTMP/Featherwood Drive Neighborhood – Neighborhood Traffic Management Program Speed and volume traffic counts were collected at three locations along Featherwood Drive between Sylvan Glen Road and Looking Glass Drive. The data shows speeds between 25 MPH to 28 MPH. Based on CVC 22350, “No person shall drive a vehicle […] at a speed greater than is reasonable or prudent […] and in no event at a speed which endangers the safety of persons or property”. The City’s residential street speeds are posted at 25 MPH. The original requestor has been kept updated all along. Staff is currently working with the Sheriff’s Department to patrol the area when possible. Meanwhile, staff will continue to consider other countermeasures that the collected traffic data support. 3.B Packet Pg. 18 F. NTMP/Hawkwood Drive Neighborhood – Neighborhood Traffic Management Program In late June, the NTMP petition letters were mailed to the residents in the Hawkwood Drive neighborhood. The survey response rate was low . About 21% of residents from Area 1 and 13% of residents from Area 2 participated in the petition. The City was made aware that several residents did not have the opportunity to participate due to not receiving the letter or being unable to access the online petition form before the closing date. The City will not be able to move forward with the NTMP if there is low interest in the program. To provide opportunities for more residents to participate, the City has mailed out a new letter/notice and re-opened the petition for an additional four (4) weeks. Staff continues to work with the neighborhood NTMP captain to encourage a s much participation as possible. G. NTMP/Del Sol Lane Neighborhood – Neighborhood Traffic Management Program Staff held a kickoff meeting with the selected Traffic Engineering Consultant, Kimley Horn, to prepare the construction plans for the Del Sol Lane NTMP. The Consultant has been provided with the traffic speed and volume data collected in the neighborhood, as well as the residents' opinions that were shared in the first neighborhood meeting. The traffic calming design plans will be presented at a second NTMP neighborhood meeting where the residents will have the opportunity to share their thoughts and concerns on the proposed measures before finalizing the design. H. Diamond Bar Boulevard Rehabilitation (Mountain Laurel Way to Pathfinder Road) Construction of the project was completed in early August prior to the start of the school year. The work included a 2” - 4” mill and overlay of the pavement including the full intersections, new and improved ADA curb ramps, curb/gutter and sidewalk replacement, new traffic loops, a rehabilitated bus pad at Silver Hawk Drive, and enhanced bike lane striping along the entire corridor. The project was completed on schedule and under budget. Final administrative paperwork is being completed to close out the project. I. New Street Name Signs for Niagara Bottling Company On August 20, 2021, Public Works installed four (4) new illuminated street name signs at the intersection of 1440 Bridgegate Drive, where Niagara Bottling Company occupies the sole property served by this intersection. Previously, the signs read the property 3.B Packet Pg. 19 address, but are now personalized to read “Niagara Way.” This is the first installation of the City’s new design for the illuminated street name sign, which features the City’s Windmill logo and the latest styling. All other signalized intersections will also receive these updates in a future City project. Public Works has determined that these new signs will improve wayfinding along Bridgegate Drive for employees, visitors, couriers, and emergency services. The sign replacement was approved at the December 15, 2020 City Council meeting and is paid for by Niagara Bottling Company. The attached Exhibits “A” and “B” detail the previous and newly installed signs for Niagara Bottling Company. J. Upcoming Construction Projects Staff approved plans and issued encroachment permits for several utility improvement projects that are anticipated to start construction in the coming weeks: • Tesla – 2785 S Diamond Bar Boulevard o Installation of Twenty-Four (24) New Tesla V3 Supercharger Stations • MCI Metro (Verizon) – Golden Springs Drive from Golden Prados Drive to Ballena Drive o Final Asphalt Restorations (Slurry Seal + Striping) • MCI Metro (Verizon) – Grand Avenue from Montefino Avenue to Diamond Bar Boulevard o Installation of New Underground Fiber Optic Cable • MCI Metro (Verizon) – Grand Avenue from Diamond Bar Boulevard to Summitridge Drive o Installation of New Underground Fiber Optic Cable • Southern California Edison –Torito Lane at Golden Springs Drive o Installation of New SCE Electrical Vault Public Works staff is committed to ensuring that all construction impacts are properly mitigated to limit the effect on our community. The City’s Public Works Inspector monitors all active utility construction projects to ensure that work is completed per the approved plans and permit conditions. K. Local Roadway Safety Plan (LRSP) A prioritized list of countermeasure projects for the Highway Safety Improvement Program (HSIP) was identified in the LRSP final report. Staff is currently reviewing the 3.B Packet Pg. 20 list and will identify the projects with high cost-effectiveness that will have the greatest chance of receiving federal funding in Caltrans’s HSIP grant call -for-projects. Applications for Cycle 11 of the grant program are due April 2022. A final proposed list of project(s) will be presented at a future Traffic and Transportation Commission meeting. L. Diamond Bar Golf Course Renovation Project In conjunction with the Grand Avenue and Golden Springs Drive Intersection Improvements Project, the Diamond Bar Golf Course Renovation Project is a precursor to the SR-57/60 Confluence Project. As a result of the acquisition of right -of-way from Diamond Bar Golf Course for the Confluence Project, six (6) course holes of the golf course will be directly impacted and required to be reconfigured along the SR-57/60 frontage and Grand Avenue. Therefore, all eighteen (18) golf course holes will be modified. During the renovation project, all facilities of the golf course will be temporarily closed beginning September 1st.
