Under California Streets and Highways Code Section 93, Caltrans is authorized to construct and maintain detours as may be necessary to facilitate the movement of traffic where state highways are closed or obstructed by construction or otherwise.

Adaptive Traffic Signal Control Signal System (ATCS) One of the main objectives of the ATCS is to move more traffic along the main arterials during rush hours. The City's ATCS was originally configured to be activated during rush hours, however, due to the significant decrease in main arterials traffic during COVID-19, the ATCS was configured to reprioritize and minimize the wait time for traffic coming out of the side streets, while traffic was light along the main arterials. In the last couple of months; however, staff has observed an increase in rush-hour traffic. Therefore, the ATCS has been adjusted to allow more arterial traffic during weekday rush hours. B. NTMP/Del Sol Ln Neighborhood —Neighborhood Traffic Management Program On May 26ih, the City received a report of speeding concern along N Del Sol Lane between Sunset Crossing Road and Cougas Creek Road, and on Highland Valley Road between N Del Sol Lane and Overlook Ridge Road — attached is a map of the neighborhood. The NTMP was launched and traffic detectors were placed throughout the neighborhood to collect speed and volume data for seven (7) consecutive days in the areas of concern, which include N Del Sol Lane and Highland Valley Road. Once the data is organized and sorted by the vendor, the City will review and share the results with the neighborhood captains/residents. Packet Pg. 16 C. Grand Avenue/Golden Springs Drive Intersection Improvements The intersection improvements project, will include slope grading at the southeast corner of the intersection. To prepare for and create space for the regraded slopes, Hole #3 needed to be relocated. In the past few weeks, Hole #3 was relocated and graded; and irrigation lines and new sods were installed. This work is now completed. It is separate from the Diamond Bar Golf Course Renovation Project, a major improvements project and a precursor to the 57/60 Confluence Project. As for the main intersection improvements project, before starting any construction work on the roadway, storm drain, tunnel relocation, retaining walls and grading, a Temporary Construction License (TLC) agreement needs to be executed between the County of Los Angeles, as the owner of the Golf Course, and the City of Industry that is in charge of the construction work. The TLC has not been executed to date. The road work and intersection construction is tentatively scheduled to commence in January/February 2021, D. Diamond Bar Boulevard Complete Streets Corridor The design phase of the project has been completed. Staff received the 100% Plans, Specifications, and Estimates (PS&E) documents from the project consultant. Staff continues to pursue additional funding for the construction phase of the project. E. Diamond Bar Boulevard Rehabilitation (Mountain Laurel Way to Pathfinder Road) Plans and Specifications are in the final review stage for a pavement rehabilitation project on Diamond Bar Boulevard beginning where last year's project left off on Mountain Laurel Way and ending at Pathfinder Road, The Project will consist of a 2" - 6" pavement grind and upgraded or newly constructed ADA curb ramps where the existing ramps do not meet current ADA standards. Staff plans to finalize the design as soon as possible. Once the design is complete, plans will need to be approved at a regularly scheduled City Council Meeting prior to soliciting construction bids. Given the upcoming holiday schedule construction is likely to begin in 2021, consistent with the schedule of last year's project. F. Traffic Signal Battery Backup Project Battery backup units are a critical part of the City's public safety efforts as they allow traffic signals to fully operate for a short period of time then operate on red flash for several hours in an emergency situation resulting in a power outage. The City of Diamond Bar has a total of 66 signalized intersections. To date, the City has installed battery backup systems at 55 of the signals. This final project has installed eleven (11) new battery backup systems on the remaining intersections that do not already have one in place, bringing the total to 66. The locations are: 1. Brea Canyon Road & Glenbrook Drive 2. Brea Canyon Road & Lycoming Street 3. Brea Canyon Road & Silver Bullet Drive 4. Brea Canyon Road & Washington Street 5. Brea Canyon Cut Off & Oak Crest Drive 6, Brea Canyon Cut Off & Fallowfield Drive 7, Bridgegate Drive at 1440 Bridgegate Drive 8, Gateway Center Drive & Valley Vista Drive 9, Golden Springs Drive & Sylvan Glen 10. Pathfinder Road & Peaceful Hills Road 11. Chino Hills Parkway & Chino Avenue This project began on October 9, 2020 and was completed on October 16, 2020. All 11 battery backup units have been successfully installed and tested. The City now has functional battery backups for all 66 of the City -operated signals. G. New City of Diamond Bar Transportation Study Guidelines for Vehicle Miles Traveled and Level of Service Assessment Changes in state law have fundamentally redefined how project -generated traffic impacts are measured under the California Environmental Quality Act (CEQA). Rather than evaluating how a project affects motorists, CEQA now requires the impact of project -generated traffic to be measured in terms of its contribution to greenhouse gas (GHG) emissions. The new metric used to assess such impacts is "Vehicle Miles Traveled" (VMT), replacing "Level of Service" (LOS) as the measure of transportation impacts in environmental impact reports and other CEQA documents. To establish new baselines and thresholds of significance to evaluate VMT impacts the City Council, at its July 21, 2020 meeting adopted Resolution No. 2020-30. Subsequently, the City's Traffic Impact Analysis Guidelines (TIA, Rev. 2009) had to be updated to reflect the change to the project evaluation process. The City, with the assistance of a consultant, completed a comprehensive update of the City 's TIA. The new document "City of Diamond Bar Transportation Study Guidelines for Vehicle Miles Traveled and Level of Service Assessment' (TSG) will completely replace the TIA. The TSG establishes the methodology for determining the baselines from which VMT thresholds are measured. Outside of the CEQA process, the City has the option to continue to evaluate projects using the LOS metric, and may still assess fair share fees for intersection and other roadway improvements, and Diamond Bar will continue to do so in accordance with General Plan Goals and Policies, and the new TSG.
