THIS INFORMATION WILL BE PROVIDED AT THE DECEMBER 9, 2010 MEETING CITY OF DIAMOND BAR MINUTES OF THE TRAFFIC AND TRANSPORTATION COMMISSION MEETING SEPTEMBER 9, 2010 CALL TO ORDER: Chairman House called the meeting to order at 7:03 p.m, in the South Coast Air Quality Management/Government Center Hearing Board Room, 21865 Copley Drive, Diamond Bar, California 91765. PLEDGE OF ALLEGIANCE: Vice -Chair Pincher led the Pledge of Allegiance. ROLL CALL: Commissioners Ted Carrera, Jimmy Lin, Kenneth Mok, Vice -Chair Liana Pincher and Chair Kevin House Also Present: David Liu, Public Works Director; Rick Yee, Senior Civil Engineer; Kimberly Molina, Associate Engineer; Christian Malpica-Perez, Associate Engineer (Traffic); and Marcy Hilario, Senior Administrative Assistant I. APPROVAL OF MINUTES: A. Minutes of the August 12, 2010 regular meeting. C/Carrera moved, C/Mok seconded, to approve the August 12, 2010 minutes as presented. Motion carried by the following Roll Call vote: AYES: COMMISSIONERS: Carrera, Lin, Mok, VC/Pincher, Chair/House NOES: COMMISSIONERS: None ABSENT: COMMISSIONERS: None II. PUBLIC COMMENTS: Lynn Liu, 20819 Cliffside Lane, expressed concern about the northbound Brea Canyon Road left turn lane at Diamond Point Lane and the southbound vehicles making a right turn. This blocks the left turn lane queue. She said that vehicles have to sit through three or four light cycles before being able to proceed, especially during pickup and drop-off at South Point Middle School. She requested installation of a "no right turn on red between 7:00 a.m. to 8:00 a.m. and 2:00 p.m. to 3:00 p.m. on school days." C/Carrera asked if there was a plan for the City to work with South Point Middle School staff to resolve student drop-off issues. PWD/Liu responded that Diamond Point Lane has sufficient capacity and what the speaker references is the intersection bottleneck during peak hours. Staff will investigate the reported condition. SEPTEMBER 9, 2010 PAGE 2 T&T COMMISSION IV U Chair/House felt the matter required more enforcement to stop traffic from blocking the intersection and that perhaps the school could be required to move the traffic through the drop-off area faster. ITEMS FROM STAFF: A. Received and Filed Traffic Enforcement Updates for: 1. Citations: June, July and August 2010 2. Collisions: June, July and August 2010 3. Street Sweeping: June, July and August 2010 C/Mok asked if there was a reason for the decrease in citations. PWD/Liu said that the fine print refers to an officer injury as well as a vacation period. OLD BUSINESS: None NEW BUSINESS: None VI. STATUS OF PREVIOUS ACTION ITEMS: SE/Yee reported that staff conducted a field investigation on a matter that C/Carrera brought up at the last meeting regarding morning traffic and vehicles attempting to make a u -turn in order to head westbound on Pathfinder Road at Evergreen Springs Road adjacent to DBHS. The turn movement referenced by C/Carrera has a protected -permissive left turn signal and he went on to explain how the signal timing works. The green arrow goes on first and when the signal turns red, the permissive green is still available for a left turn. Currently, the total cycle length is 65 seconds with 31 seconds dedicated to through traffic and left -turn eastbound movements. During morning hours, the westbound traffic is heavy. Staff also looked at shortening time from the side streets and accommodating a longer green on the left turn. However, taking the entire intersection into consideration, staff felt it would be best to retain the current timing program rather than to provide preferential treatment to vehicles during a very short timeframe during the day and penalize the remainder of the neighborhood. Chair/House said that at the last meeting he stated one could make a left turn out of the DBHS parking lot. In fact, it is a right -turn only onto Pathfinder Road from Brahma Road and vehicles are forced to go to the left turn lane on Pathfinder Road to make a u -turn to travel westbound. He asked why vehicles are not permitted to make a left turn out of Brahma Drive. PWD/Liu explained that he would need to check the previously approved circulation plan established for the high school and that he would provide a copy of the traffic circulation plan that was devised about five years ago by the Sheriff's Department, the City's Traffic Engineer, and the school. It appears to him SEPTEMBER 9, 2010 PAGE 3 T&T COMMISSION that the school is no longer using that plan. Chair/House said that as Commissioners they need to know all of the facts about traffic patterns in order to come to some resolution. VII. ITEMS FROM COMMISSIONERS: VC/Pincher asked why the speed limit is posted at 45 mph on Brea Canyon Road south of Pathfinder Road south of DBHS. She said it felt good to have someone come from another state and comment on how clean the City is. Chair/House felt the Pathfinder Road improvements were completed very quickly and every time he drove by the area, AE/Ching was present making sure the City was well represented. C/Lin said he believed the issue he brought up a couple of months ago about the on/off ramp at Golden Springs and Grand Avenue was still valid. C/Carrera asked about the scope of work being done on Diamond Bar Boulevard at Albertsons and the Post Office. AE/Malpica-Perez explained that the purpose of the work is to improve the line of sight issue by realigning the medians for better access to the post office and the Allegro condominiums. Chair/House asked if there was reason for the red cones on Pathfinder Road westbound lanes. SE/Yee explained that the project is substantially complete with minor punch list items remaining. At the conclusion of the project, the cones will be removed. VIII. INFORMATIONAL ITEMS: A. Diamond Bar Boulevard Median Modification —AE/Malpica-Perez reported that the project is in its last phase with completion scheduled for early next week. Once completed, the project is expected to improve the line of sight for vehicles making a left turn from Diamond Bar Boulevard into the post office and Allegro Condominiums. B. Diamond Bar TMS/Traffic Signal Interconnect Links — SE/Yee stated that staff has made substantial progress on the integration of the CCTV, eight of which have been installed. Currently, there is streaming video coming into City Hall and remote control to pan, tilt and zoom each of the cameras. The streaming video quality is being tweaked as well as minor communication issues that will need to be resolved. The project is substantially complete. VC/Pincher asked if the Commissioners would have an opportunity to view the system. SE/Yee explained that staff is moving in that direction and hopes to be able to demonstrate the features of the system in a couple of months. C. Traffic Signal Battery Backup System Project — AE/Malpica-Perez explained that the City's traffic consultant configured eight of the battery backup units last week. Once the configuration is complete, staff will be able to monitor those units during power outage events. SEPTEMBER 9, 2010 PAGE 4 T&T COMMISSION D. Industry's Grand Avenue Bridge Widening/Interchange Project — SE/Yee stated that this is a two -phased project with the first phase being construction of the westbound SR -60 slip ramp on the border of City of Industry and D.B. The environmental document for the first phase is scheduled for public circulation sometime in October, with construction contemplated to commence in 2012. The second phase consists of the Grand Avenue bridge widening, construction of by-pass roads from eastbound SR -60 to Grand Avenue and from Grand Avenue to the eastbound SR -60, as well as the Grand Avenue ramp reconfiguration. The second phase is currently in the environmental document development phase. Staff continues to attend monthly project update meetings and have tentatively scheduled a study session with the City Council sometime in November. Commissioners will be invited to attend, E. SR -57/60 Feasibility Study — SE/Yee reported that this joint study between Metro, City of Industry and D.B. looked at the SR -57/60 interchange to determine potential improvement alternatives. Three major alternatives were discussed: Alternative A - New connections, Alternative B — Separation of the two freeways by laying them side by side, and Alternative C— Double decking of the two freeways. The general conclusion of this study released last week indicated that all three alternatives have similar performance with respect to traffic operations while differing substantially in cost. Alternative A appears to be the lowest cost and will provide the least amount of residential property impact. At the same time, all three alternatives have relatively comparable impacts in terms of their right-of-way costs. This item is anticipated to be included in a City Council study session update for November and, again, the Commissioners are invited to attend that study session. C/Lin asked if the Commissioners could receive a summary report prior to the study session. SE/Yee said that staff plans to provide a packet to the Commissioners prior to the actual presentation. F. Pathfinder Median Improvement Project — SE/Yee reported that the project is substantially complete with minor punch list items to be completed. This project was funded with grant funds — mainly the Highway Safety Improvement Program, as well as some contribution from Prop C local fund budget. G. Environmental Enhancement Mitigation (EEM) Improvement Project- SE/Yee stated that this project is also funded through grantfunds in an amount close to $300,000. Across from Caltrans property on Golden Springs Drive, there is quite a bit of irrigation line and most of the system will be above ground with a layer of mulch to cover the unsightly area. On the slope along Via Sorella and Brea Canyon Road there is above -ground irrigation which will receive plantings. The end result will also include a layer of mulch to improve the landscape. H. Lemon Avenue On/Off Ramps Project — AE/Molina reported that 95 percent plans were completed and distributed to all Caltrans divisions responsible for reviewing the plans as well as, to the City and its consultant. There will be a meeting next Wednesday to go over all critical comments on the 95 percent plans. Additionally, staff provided a full written project update in the Commission packets. The right-of-way acquisition will commence at the SEPTEMBER 9, 2010 PAGE 5 T&T COMMISSION beginning of 2011 and continue for 18 months with construction for the two- year project beginning in 2012. C/Carrera asked who would assume ownership and on-going maintenance of the retaining wall. AE/Molina said this issue was under review. It is believed that Caltrans will maintain structural responsibility for the retaining wall — the aesthetic responsibility will be negotiated between the state and the City with respect to graffiti control. C/Lin asked if there would be a taking of private properties. AE/Molina replied there were five (5) partial takes along the residential rear yards of Flintage Drive and two property takes of commercial properties to accommodate a curb ramp and eastbound on-ramp. Caltrans will negotiate the takes. C/Lin asked if there was any damage reimbursement for businesses. AE/Molina responded that the City conducted an independent economic analysis of the impacts to the intersection of Golden Springs Drive and Brea Canyon Road once the existing hook ramps are closed. As a way to mitigate any losses, Caltrans agreed to have the new eastbound off -ramp signage read Lemon Avenue/Brea Canyon Road and once a vehicle exits onto Lemon Avenue, "way finding" signs will be incorporated to get motorists back to the shopping center through Lemon Avenue and Golden Springs Drive. I. Residential — Area 6 Slurry Seal Project — AE/Molina reported that all of the streets that were designed to have the grind overlay treatment have been completed. Slurry seal operations commenced last week and due to the unseasonably cool and damp weather, the work could not be completed as scheduled. Therefore, the slurry seal will continue until Monday of next week. Once completed, the striping will be installed to complete the entire Area 6 project. J. NTMP — Maple Hill Road, Cleghorn Drive/Gold Nugget Avenue, and Briar Creek Road/Decorah Road Neighborhoods — SE/Yee updated the Commission and thanked everyone who attended the most recent neighborhood meeting. Staff is looking to coordinate and collaborate with the neighborhood to have them obtain the necessary signatures to gain consensus for the concept plan. Staff has had a bit of difficulty getting in touch with individuals who volunteered to lead the effort. There was additional discussion regarding school traffic circulation and related issues. PWD/Liu reported that the City officially closed escrow and became the owner of the building across the street last week. Staff is currently working with the architects on interior improvements which should be finished in about a year. IX.
