Street Sweeping: OLD BUSINESS August, September, October 2007 A. NTMP Pilot Project — Assessment of Before and After Data AE/Molina presented an overview of the project and subsequent evaluation and findings for each area as called out in staff's report. Chair/Shay asked what staffs expectations were regarding the effect of the installations on traffic volume. AE/Molina responded that areas in and around schools are typically not affected to any great extent. In areas such as Sunset Crossing Road and Fountain Springs Road, staff's goal was to provide measures that would make it inconvenient for cut -through traffic. PWD/Liu stated that these measures were installed as a direct result of input regarding the residents' concerns. Therefore, the measure of its success is whether the mitigation achieved the residents' expectations while remaining cost-effective. C/House asked how many signatures were required on petitions to launch the program. AE/Molina responded that when the City receives a request for speed bumps or other traffic calming devices, a letter is sent to the individual who initiated the request identifying the neighborhood that would be affected by such a request and include a petition indicating the initiator of the request would need to obtain signatures from 51 percent of the affected residents. C/House asked for information about stop sign warrant criteria. Mr. Castorena (from the audience) asked about how long the process takes. AE/Molina responded that from the time the City receives the petition launching the program, staff attempts to schedule the introductory meeting within four weeks depending on holiday schedules, etc. The process from request to design of proposed measures takes about six months C/Pincher moved, Chair/Shay seconded, to receive and file the report and approve receipt of the technical data.

ITEMS FROM COMMISSIONERS: House, Lin, Pincher, VC/Mok, Chair/Shay None None None NOVEMBER 8, 2007 PAGE 3 T&T COMMISSION C/Lin stated that traffic was moving great and the traffic has decreased significantly on Diamond Bar Boulevard since completion of the HOV lanes. C/Pincher asked if Caltrans planned to put a signal at the southbound SR57 at Diamond Bar Boulevard and Brea Canyon Road. PWD/Liu indicated that the matter is in design phase and awaiting Caltrans approval. The City plans to complete the installation from its Capital Improvement budget. PWD/Liu explained the video camera technology to C/House and indicated that most locations maintain the advance loops. C/Lin asked if the golf course issue was dead. PWD/Liu responded that the City Council would be discussing this matter as part of its goals and objectives discussion at the next Council meeting. In addition, the City continues to discuss Grand Avenue improvements with the City of Industry and Caltrans for possible impacts to the golf course. VII. INFORMATIONAL ITEMS A. ACE Grade Separation on Brea Canyon Road — SE/Yee reported that the project continues to move forward with completion scheduled for Fall of 2008. 13. Various Traffic Signal Improvements on Golden Springs Drive — SENee reported that a second left -turn pocket from westbound Golden Springs Drive to southbound Brea Canyon Road and video detection were recently completed. C. NTMP/Sunset Crossing Road and Prospectors Road traffic calming improvements — SE/Yee reported that staff was fine-tuning additional scope of work items and design is scheduled to be underway in the next couple of weeks with a first submittal in December. D. Industry's Grand Avenue Bridge Widening/Interchange Project — PWD/Liu stated that the City's objectives are to provide lasting congestion relief through the Grand Avenue corridor; assure local circulation impacts are mitigated and, minimize impacts to developed properties (Honda Dealership, golf course and residential properties). E. Lemon Avenue On/Off Ramps Project — PWD/Liu reported that the consultants were working on specific documents and expected the environmental document to be circulated in January/February 2008 with final design to commence in April 2008, final design approval about September 2009 and award of construction contract in 2010 with construction completion slated for 2012. F. SR57/60 Feasibility Study— PWD/Liu stated that the City's objectives are that the improvements provide long-term congestion relief, minimize the impact to developed properties within the City and ensure that the improvements are integrated and coordinated with the Grand Avenue Interchange Project. Staff NOVEMBER 8, 2007 PAGE 4 T&T COMMISSION suggested three concepts for further study: 1) missing freeway connectors and carpool extension concept; 2) parallel SR57/60 concept; and, 3) double -deck or tunnel option. C/Lin expressed that funding would be a big issue and the alternative should provide a cost benefit. In his opinion, the "missing link" is probably the least desirable of the alternatives because the missing link does not serve D.B. to any great extent; the more appropriate alternative is the 71 Freeway. PWD/Liu said that staff was fully aware of the issues. However, the City's approach is to put all options on the table for consideration. Staff believes the ultimate solution is a CD system that addresses the weaving issue and the Grand Avenue interchange will be a key component of the freeway improvements. The good news is that in its 20 -year planning document the MTA has identified that this interchange needs to be addressed and the money will have to be budgeted. G. Annual Slurry Seal Program — AE/Molina reported that work in Residential Area 3 and Arterial Zone 1 along Diamond Bar Boulevard continues because some areas of striping did not meet the degree of workmanship required by the City. Once work is satisfactorily completed, staff will take the Notice of Completion to Council for approval. H. NTMP Project/Palomino Drive—AE/Molina stated that the second meeting for the neighborhood is scheduled for December 10th and the consultant is putting together a list of proposed mitigation measures to address the neighborhood concerns. Prospectors Road Rehab. Project — A contract was awarded and executed with RJ Noble to rehab the roadway from Sunset Crossing Road to Golden Springs Drive. Construction is on hold until after the first of the year so as not to inconvenience residents during the holiday season and to coordinate construction with the traffic -calming project. VIII. SCHEDULE OF FUTURE CITY EVENTS: As listed in the Agenda. PWD/Liu asked for the Commissioners to consider whether they wished to go dark for the December 13th meeting and instead attend the NTMP meeting for the Palomino Drive neighborhood. The Commissioners concurred. AE/Molina announced that the City's Holiday Party was scheduled for December 14'x' at the Diamond Bar Center Ballroom.
