PWD/Liu confirmed C/Pincher's statement that if someone harassed the CSO to the point where he felt it was necessary to call for assistance he could do so.

Motion carried by the following Roll Call vote: AYES: COMMISSIONERS: Mahlke, Pincher, Pirritano, VC/Mok, Chair/Carrera NOES: ABSENT: OLD BUSINESS NEW BUSINESS COMMISSIONERS: COMMISSIONERS: None None STATUS OF PREVIOUS ACTION ITEMS: VII. ITEMS FROM COMMISSIONERS: None None None Chair/Carrera shared that he observed the morning traffic backed up on Diamond Bar Boulevard at Mountain Laurel Way on its way to Lorbeer Middle School. He asked for the methodology for allowing the traffic to turn right while still allowing the southbound Diamond Bar Boulevard traffic to proceed through. AE/Malpica explained that staff has been out in the field observing students crossing, as well as vehicular turning movements at this intersection since late last week. The current crossing guard is new to this location (about 2 weeks or so), and she is still on a learning curve. In the AM peak hour during the school drop-off time, both pedestrian and vehicular traffic are heavy. Balancing the needs of these two user groups is key to reducing the congestion concern. We have an established one-way vehicular circulation pattern to and from Chapparal Middle School. If we pushed too many vehicles through this intersection, we could end up with more congestion issues in this neighborhood. Staff has been discussing our observations with the new crossing guard to ensure that she manages this intersection effectively and efficiently. FEBRUARY 14, 2013 PAGE 3 T&T COMMISSION Staff is also looking at the feasibility of extending the right turn pocket (on southbound Diamond Bar Boulevard) to store more vehicles for right -turn movement and to minimize heavy congestion on the thru lanes. Upon consulting with our traffic engineer about some timing improvements, the traffic engineer suggested running this intersection on free mode. This way, we do not shorten the green time from other phases (directions). The free mode will provide the necessary green time for each direction depending on the demand, especially during the 15-20 minute school rush hour. PWD/Liu stated that staff has been reviewing the current traffic flow plan around the school for the past couple of weeks and will be working with the parents and school authorities to help mitigate this situation. Chair/Carrera said that the flow works well. The right turn pocket is set up for a non - traffic condition; however, when there is a greater traffic flow condition, there are more people waiting to turn right, which slows traffic. He understands why staff would not endorse a longer right -turn lane. VIII. INFORMATIONAL ITEMS: A. CDBG Curb Ramp Project AE/Malpica stated that the contractor has completed all of the CDBG curb ramps in the Peaceful Hills Road/Pathfinder Road area. The construction crew is currently working on the Gateway Center area which should be completed by the end of next week or the middle of the following week. B. CCTV Project AE/Malpica indicated that the contractor will commence installation of cameras at eight locations next Monday, which will take approximately three weeks after which testing will commence. The project is anticipated to be completed by the end of March, weather permitting. C. Median Project at Grand Avenue and Summitridge Drive AE/Malpica explained that this project is part of the retrofitting project that commenced in 2008. The City's consultant checked all of the intersections for possible line -of -sight issue throughout the City, made an assessment of the six locations and presented his recommendation to staff. To date, three locations have been completed. The Grand Avenue and Summitridge Drive location is the fourth location slated for improvement. This project should be completed by the end of March. FEBRUARY 14, 2013 PAGE 4 T&T COMMISSION D. Traffic Signal Operation and Maintenance Master Plan AE/Malpica stated that the purpose of this plan is to provide a comprehensive study of the City's traffic signal system, to examine the current hardware and software, and to make an assessment of the current coordination and maintenance efforts and, most importantly, to identify any deficiencies. This roadmap will provide the basis for recommended improvements. This plan should be completed within the next three to four months. PWD/Liu explained that when looking at the age and condition of some of the signalized intersections, these existing traffic signals are more than 30 years old. This report would lay the groundwork for future operation and maintenance of the City's traffic signal system. E. SR57160 Confluence at Grand Avenue Project — Public Hearing PWD/Liu announced that, working alongside Caltrans, there will be a public hearing on March 6th from 5:30 p.m. to 8:00 p.m. at SCAQMD in the GB Conference Room. The purpose of this public hearing will be to discuss the two-mile long confluence area along the SR -57/60 that includes proposed auxiliary lanes and on/off ramp re -configurations. From 5:30 p.m. to about 6:15 p.m., attendees will have an opportunity to view mockups of the project. At 6:15 p.m., Caltrans will make a presentation after which the Q&A session will continue until 7:15 p.m., with an opportunity for the public to interact with staff and Caltrans until 8:00 p.m. This is a major first step toward the "Big Fix" improvements and Industry's effort to widen the Grand Avenue bridge/overpass across the freeway. Caltrans recently completed the Draft Environment Impact Report in which they evaluated the potential impacts of the no-build/build improvement alternatives. The Public Hearing notice has been published in various newspapers, as well as the March issue of the City's newsletter. The review period commences February 18th and continues to April 5, 2013 when the public review period ends. VC/Mok asked how extensive the advertising would be for the public to attend the hearing. PWD/Liu responded that this item will be on the front page of the March City Newsletter. In addition, the public hearing notice will be published in various newspapers such as the San Gabriel Valley Tribune, La Opinion and others. Also, the City of Industry has setup the website www.freetheway.org which is dedicated to the SR -57/60 and will provide a link to the public hearing meeting and the Draft EIR document. A copy of the Draft EIR will be available for public viewing at the Diamond Bar Public Library. VC/Mok asked staff to notify Gina from the Diamond Bar/Walnut Patch as well. PWD/Liu thanked VC/Mok for this reminder. Chair/Carrera encouraged Commissioners and members of the public to attend this significant public hearing and assist in moving this project forward. FEBRUARY 14, 2013 PAGE 5 T&T COMMISSION PWD/Liu further stated that the golf course designer and L.A. County representatives will be present at the public hearing to talk about how this project will impact the golf course and require a complete reconstruction. IX.
