APPROVAL OF MINUTES: Minutes of the June 14, 2007 meeting — continued to the August 9, 2007 Meeting. II. PUBLIC COMMENTS: Genea Wall, 1557 Meadow Glen Road, spoke in favor of a crossing guard at Mountain Laurel Way on Diamond Bar Boulevard. SE/Yee responded to the speaker that at its June 14, 2007 meeting, the Traffic and Transportation Commission concurred with the findings of the crossing guard warrant study that a crossing guard was not warranted at the location. At the Commission's recommendation, staff engaged in discussions with school officials at Chaparral Middle School and determined that the school principal was very proactive in school traffic safety. In addition to addressing the issue on the PA system on a daily basis, the school and the Sheriff's Department provide consistent and ongoing safety education for the students and parents. Additionally, staff has provided additional recommendation for striping and signage on every leg of the intersection as well as split phasing of the traffic signal that would provide isolated crosswalk movement on the north leg of the intersection. This information was provided during a community meeting that Ms. Wall attended. At the conclusion of the community meeting residents acknowledged staff's proposal would be helpful. Staff intends to bring this matter to the City Council on August 7th C/Pincher asked if there was a possibility to post flashing lights during school crossing hours as an added alert for drivers. PWD/Liu said it was an option that involved July 12, 2007 PAGE 2 T&T COMMISSION IV. additional signage at a signalized intersection and flashing lights would be more appropriate at un -signalized intersections to not confuse the issue. Ms. Wall said she believed adult presence would greatly help mitigate the situation at the intersection because young children were not responsible enough to fend for themselves. CONSENT CALENDAR: A. Traffic Signal Warrant Analysis for Grand Avenue/Cahill Place and Grand Avenue/Gleghorn Drive. PWD/Liu referred to staff's report and recommended that the Commission concur with staff's findings. C/Shah moved, C/Pincher seconded to recommend that the intersections of northbound and southbound Grand Avenue from Cahill Place and Cleghorn Drive remain un -signalized.

Street Sweeping: March, April, May and June 2007 V. OLD BUSINESS: None VI. NEW BUSINESS: A. Traffic Concerns along Pathfinder Road west of Brea Canyon Road and east of the SR57. SE/Molina presented staff's report and recommended that the Traffic and Transportation Commission concur with staff to install Texas dots along the median striping along Pathfinder Road west of South Brea Canyon Road and east of the SR 57. C/Shah wanted to know if staff had considered a landscaped median at this location in place of Texas dots. PWD/Liu responded that landscaped medians provide good traffic control but require considerable resources. In addition, 1 1 �1_ July 12, 2007 PAGE 3 T&T COMMISSION landscaped medians are not installed to prevent illegal maneuvers. This proposal is an interim measure to mitigate illegal moves. C/Pincher was concerned that the no -left turn sign at the Denny's Restaurant entrance was missing. She was also concerned about the behavior of the drivers exiting the driveways and wondered why the Texas dots would not be installed all the way to the bridge. SE/Molina responded that the dots could be installed from the bridge to the crosswalk. However, she would have to check with the City's traffic engineer to see if it was acceptable to place them inside the median area. At this time there is no additional striping contemplated. SE/Molina said staff would modify the recommendation to include dots along all of the striping from crosswalk to crosswalk. SE/Molina indicated to VC/Mok that affected businesses and property owners along Pathfinder Road were notified of this meeting as well as staff's recommendation. C/Pincher moved, VC/Mok seconded to concur with staff to install Texas dots along the median striping on Pathfinder Road west of Brea Canyon Road and west of the SR 57. C/Shah asked for the maker of the motion to modify her motion to request that staff develop a priority list for medians based on need. C/Pincher concurred with the recommended amendment and VC/Mok seconded the amended motion. Motion carried by the following Roll Call vote: AYES: COMMISSIONERS: Pincher, Shah, VC/Mok NOES: COMMISSIONERS: None ABSENT: COMMISSIONERS: Lin, Chair/Shay VII. STATUS OF PREVIOUS ACTION ITEMS AE/Molina reported that in February staff received a request from a concerned resident about speeding and cut -through traffic along Palomino Drive. In accordance with the Neighborhood Traffic Management Program manual guidelines, 51 percent of the residents are required to sign a petition in favor of launching the NTMP. The individual requesting the mitigation was advised of the requirement and obtained signatures in excess of the 51 percent required. On June 28'h, staff held a meeting with residents living on Palomino Drive. About 20 residents of Palomino Drive and neighboring streets attended the meeting and provided valuable input. Staff recorded the meeting and will be taking a four-day traffic volume and speed data count on Thursday, Friday, Saturday and Sunday to develop an action plan for addressing the concerns. At a subsequent meeting staff will provide information regarding possible mitigation tools. VIII. ITEMS FROM COMMISSIONERS C/Pincher asked if it was still appropriate to have a left turn lane from westbound Grand Avenue into the shopping center immediately east of Diamond Bar Boulevard. When exiting the shopping area drivers make illegal left turns onto westbound Grand July 12, 2007 PAGE 4 T&T COMMISSION Avenue across traffic. PWD/Liu recalled that several years ago staff attempted to work with the shopping center owner to create a better circulation pattern and the City was asked to keep the circulation as it had been for many years. As a result, the City installed river rock with median openings to allow the access. Staff will investigate to determine if additional measures can be implemented to address the illegal left turn movement from the shopping center onto westbound Grand Avenue. C/Shah said that at Golden Springs Drive and Grand Avenue the left and middle lanes do not line up properly because of the two left -turn pockets causing motorists to become confused and move over into the wrong lane. He asked staff to investigate the matter and report back to the Commission. IX. INFORMATIONAL ITEMS Staff updated the Commission on the following items: A.
