PLEDGE OF ALLEGIANCE ROLL CALL: Absent: Also Present: I. APPROVAL OF MINUTES: Commissioner Quan led the Pledge of Allegiance. Commissioners Mahendra Garg, Cynthia Quan Vice Chair Surendra Mehta Commissioner Shokoufeh Mirzaei and Chair Ed Pechy David Liu, Public Works Director; Kimberly Young, Senior Civil Engineer; Christian Malpica, Associate Engineer; and Marcy Hilario, Administrative Coordinator. A. Minutes of the May 12, 2016 Regular Meeting C/Garg moved, VC/Mehta seconded, to approve the Minutes of the May 12, 2016 Regular Meeting: Motion carried by the following Roll Call vote:. AYES: COMMISSIONERS: Garg, VC/Mehta NOES: COMMISSIONERS: None ABSTAIN: COMMISSIONERS: Quan ABSENT: COMMISSIONERS: Mirzaei, Chair/Pechy II. PUBLIC COMMENTS: None III. ITEMS FROM STAFF: A. Receive and File Traffic Enforcement Updates for: 1. Citations: March, April and May 2016 2. Collisions: March, April and May 2016 3. Street Sweeping: March, April and May 2016 JUNE 9, 2016 PAGE 2 T&T COMMISSION C/Garg asked why there was such a large discrepancy between May 2015 and May 2016. PWD/Liu answered that when comparing statistics, there have been additional citations issued during May 2016 because the City now has additional CSO coverage in response to concerns about additional parking enforcement on street sweeping days. VC/Mehta moved, C/Quan seconded, to receive and file the Traffic Enforcement Updates for March, April and May 2016. Motion carried by the following Roll Call vote: AYES: COMMISSIONERS: Garg, Quan, VC/Mehta NOES: COMMISSIONERS: None ABSENT: COMMISSIONERS: Mirzaei, Chair/Pechy IV. OLD BUSINESS: None V. NEW BUSINESS: None VI. STATUS OF PREVIOUS ACTION ITEMS: None VII. ITEMS FROM COMMISSIONERS: C/Garg said he understood stop signs were not warranted on Birdseye Drive and asked if instead of stop signs, a couple of speed bumps could be installed. PWD/Liu explained that speed cushions are traffic calming tools the City uses. The Neighborhood Traffic Management Program (NTMP) is a collaboration between staff and the affected residents, and to implement this program, it must be initiated by the residents. For example, if residents come to the Commission to say they have a problem on their street, whether it be speeding, cut -through traffic or some other issue, they must do so with at least 51 percent of the residents of that particular area having signed a petition asking staff to initiate the program. At that point, staff will commence engineering studies of the area to see if it is warranted to design and construct the improvements. Staff has learned that without the communication and collaboration between staff and most of the affected residents, the program is likely to fail. Once the engineering data (traffic counts, accident history, etc.) is received, it is imparted to the residents and, along with a conceptual mitigation/traffic calming plan, that plan is then discussed with the residents. If 67 percent of the residents support the concept plans, staff will begin the design plans and set aside an amount in the Capital Improvement Program budget to proceed with the improvements. Staff's advice to the Commission is that when there are neighborhood traffic concerns about residential streets, a request for consideration of any mitigation should be initiated by the residents. JUNE 9, 2016 PAGE 3 T&T COMMISSION C/Quan encouraged C/Garg to speak with the school district first because the school districts have always been able to get a good and swift response from the Sheriff's Department. In addition, the school district has been successful at calming residents and inviting them to participate in school district meetings to voice their concerns. PWD/Liu said that staff would position the radar trailer to gather information after school starts, toward the end of August. Until school starts, the information will not represent the true traffic conditions in terms of school related traffic. During the next few months, Commissioners can talk with residents and suggest they come to the Traffic and Transportation Commission meeting to voice their concerns, should they have any. VC/Mehta reiterated his concerns about the Copley Drive and Golden Springs Drive intersection and asked if something could be done about there being a "no turn on red" sign installed. Staff will incorporate that into the review for the design of the intersection modification project. VIII. INFORMATIONAL ITEMS: A. Traffic Signal Infrastructure Upgrades Project, Phase I & Phase II — AE/Malpica reported that for Phase I, the contractor has completed removal of the interconnect copper cable and installed twenty-one (21) number 6 pull boxes and eleven (11) new conduit extensions along Pathfinder Road and Diamond Bar Boulevard. Staff continues to work closely with the contractor to avoid any unnecessary delays. Phase II project design is underway with tentative completion in July. B. Adaptive Traffic Control Signal System— RFP —AE/Malpica stated that staff received five proposals on May 20th. Proposal evaluation is scheduled for the last week of June, with a tentative interview of potential consultants by the second week of July and presentation of a contract to the City Council in August. C. Copley Drive/Golden Springs Drive Intersection Enhancements — AE/Malpica indicated that staff is developing a Request for Proposal (RFP), which is scheduled to be issued in the next couple of weeks. D. Area 4 Road Maintenance Project —AE/Malpica reported that design of the Area 4 project has been completed. The project will be advertised next week with bid opening on June 30th and commencement of construction in August. E. Willow Heights Update —AE/Malpica shared that the Diamond Bar Boulevard and Brea Canyon Road Intersection Enhancement Construction Management and Construction contracts are scheduled for the June 21St City Council meeting with construction anticipated to begin prior to August. Previous to the JUNE 9, 2016 PAGE 4 T&T COMMISSION initiation of this project, utility pole relocations and intersection widening must be completed. It is necessary that Edison relocate their poles in early July so that intersection widening can take place by late July to early August. F. Morning Canyon Road Rehabilitation Project—SCE/Young stated thatthis project is nearing final design in order to go out to bid in July. A contract award will be scheduled to go before the City Council in August. Staff met with the Walnut Valley Water District in the field last month to discuss some conflicts between their existing facilities and the new curb and gutter that is being pushed out into the roadway. The City is working with the water district in an attempt to accommodate them as much as possible while maintaining the current design. G. Lemon Avenue Interchange Project — SCE/Young reported that staff met with Caltrans today. The plans are nearing final approval, possibly next week. Once staff receives final approval the hope is to move swiftly into the construction phase of the project within the next three to four months. H. SR -57/60 Confluence Project — SCE/Young relayed that construction continues on the westbound SR -60 on-ramp while striping along Grand Avenue remains as it has been for the past month. Congestion in the southbound direction remains due to the phasing of the intersection at the existing westbound on/off ramps. Staff expects this scenario to remain in place for several months as the contractor continues to worts on the westbound on-ramp. Phase II, the westbound SR -60 off -ramp, will be under construction within the next three to four months. I. TR 63623—South Pointe Residential Development—SCE/Young indicated that rough grading was completed and utility improvement construction continues for the storm drain and sewer. While the site was technically rough graded at one point, it has now been disturbed by trenching for storm drains and sewer facilities. The contractor expects this construction to continue for the next few months before they are able to finalize grading and begin construction of the residential units. Plans for Larkstone Park, which will be constructed adjacent to this development by Lennar Homes, are nearing completion. VC/Mehta asked if this project would impact traffic on major arterials. SCE/Young responded that the residential development is along Larkstone Drive and access to the development will be via Lemon Avenue and Golden Springs Drive. There was a Traffic Impact Analysis study completed, as part of the Environmental Review process for the project, and there were impacts identified. As a result, the developerwas required to submit "fair -share impact fees", which means the developer will be paying the City for impacts resulting from this development. These are funds that the City can use as needed at the intersections identified in the report. JUNE 9, 2016 PAGE 5 T&T COMMISSION Grand Avenue/Golden Springs Drive Intersection Improvements Update — SCE/Young shared that this project is still in the design phase. It is a joint project between the City of Industry and the City of Diamond Bar, which consists of mitigation required by the City of Industry's development. The City of Industry is the lead on the project and Diamond Bar is participating, since the project is in the City's jurisdiction. The project will incorporate the streetscape elements of the Grand Avenue/Diamond Bar Boulevard Project. AE/Malpica explained the 30 -day Southern California Edison rehab project taking place in front of Lorbeer Middle School and responded to Commissioners' questions and concerns. K. 2016-17 Fiscal Year Capital Improvement Projects. PWD/Liu provided an overview of the upcoming Capital Improvement Projects (CIP) for the upcoming Fiscal Year and responded to Commissioners' questions. VI.
