A. Minutes of the April 14, 2016 Regular Meeting C/Garg moved, VC/Mehta seconded, to approve the Minutes of the April 14, 2016 Regular Meeting Minutes: AYES: COMMISSIONERS: Garg, Mirzaei, VC/Mehta, Chair/ Pechy NOES: COMMISSIONERS: None ABSENT: COMMISSIONERS: Quan PUBLIC COMMENTS: None A. Receive and File Traffic Enforcement Updates for: 1. Citations: February, March and April 2016 2. Collisions: February, March and April 2016 3. Street Sweeping: February, March and April 2016 May 12, 2016 PAGE 2 T&T COMMISSION C/Mirzaei asked if there was a reason for the increase in parking citations. PWD/Liu said it was fairly static. Chair/Pechy asked if there had been an increase or decrease in the number of Sheriff's personnel. PWD/Liu responded "no." VC/Mehta asked if the citations include moving and parking violations and what constitutes a parking violation. PWD/Liu explained that both are included and on street sweeping days, there is no parking during specific hours along with other areas of the City where there are no parking anytime and no stopping anytime signs. Also, there are parking districts within the neighborhoods surrounding Diamond Bar High School where parking permits are required. Chair/Pechy moved, VC/Mehta seconded, to Receive and File the Traffic Enforcement Updates for February, March and April 2016. Motion carried by the following Roll Call vote: AYES: NOES: ABSENT: IV. OLD BUSINESS: a NJ ZIATA COMMISSIONERS: COMMISSIONERS: COMMISSIONERS: None Garg, Mirzaei VC/Mehta, Chair/ Pechy None Quan C/Garg stated that Birdseye Drive turns into Kiowa Crest; however, after that there are no stop signs on Birdseye Drive until Ironbark Drive and drivers speed on Birdseye Drive, especially along Maple Hill Elementary School. AE/Malpica indicated that a warrant analysis was done a couple of years ago and was not met for a stop sign along Birdseye Drive. The warrant analysis included traffic volumes, speed and pedestrian crossings. A traffic engineer recently reviewed this area and concluded that the warrant analysis was still accurate. PWD/Liu added that stop sign warrants require an engineering study by a licensed traffic engineer and certain criteria is required to be met. In terms of traffic control, stop signs are designed to control the right-of-way movement and are not meant to control speed of vehicles. It is regulatory signage that provides proper assignment of right-of-way priorities. Staff will follow up with the Sheriff's Department for possible increased enforcement activities, as well as communicating to the school principal that parents need to be reminded to watch out for kids in the area. In most cases, violators are residents and/or parents. VC/Mehta shared that a couple of days ago, a driver cut in front of him to make a right turn from the second lane at Copley Drive and Golden Springs Drive, which is an issue he previously discussed with the Commission. AE/Malpica responded that at this time, staff is working on the Request for Proposal (RFP) to modify that May 12, 2016 PAGE 3 T&T COMMISSION M intersection from protective permissive to protective only, as previously reported. This is part of the traffic study that includes turn lanes, line -of -sight and traffic signal operations, all of which will be addressed when this project goes through the design and construction phase. Chair/Pechy reiterated his concern about Diamond Bar Boulevard and Palomino Drive. He is still noticing that traffic is crossing over at the light on Diamond Bar Boulevard and often blocking the intersection for people attempting to exit Palomino Drive on the green light. Also, vehicles heading southbound on Diamond Bar Boulevard making a U -Turn at Palomino Drive often block the intersection during the middle of the phase so that people on Palomino Drive are unable to proceed on the green light. He noticed that there have been signs placed around the City "do not block intersection" and wondered if that type of signage might be helpful at this location. PWD/Liu said that staff would look into that and report back. With respect to congestion and U -Turns at the intersection, staff will work with the City's Traffic Engineer to see what type of signage might be effective. A. Traffic Signal Infrastructure Upgrades Project — AE/Malpica reported that Phase I of this project includes replacing 5.5 miles of copper wire with fiber optic cable, upgrade traffic controllers at 15 intersections and rewiring of three (3) intersections. This work is intended to bring all existing infrastructure up to current standards. Construction is scheduled to begin in June, with completion tentatively scheduled for September. Phase 11 is a continuation of the planned upgrades recommended in the Traffic Signal Operations Maintenance Master Plan with the following tentative schedule: City Council award of design contract to Iteris, Inc. on May 17th, bid award construction contract in August, begin construction in September, and completion of construction in December. This project will include rewiring of three (3) intersections, replacement of 4.3 miles of copper cable with fiber optic cable, update traffic signal components in the traffic signal cabinets, and replacement of 30 traffic controllers at 30 intersections. Work is being completed to bring all existing infrastructure to current standards. B. Adaptive Traffic Control Signal System — RFP — AE/Malpica shared that staff held a pre -proposal meeting on May 4th at City Hall to answer questions from prospective consultants related to the RFPs. The tentative schedule is award of design contract in July, bid award to contractor in April 2017, begin construction and implementation in June 2017, with construction and implementation to be completed by April 2018. All projects must be completed by the summer of 2018. This project will enhance the signal timing by adjusting the cycles, splits and offsets and optimize traffic flow based on real- time traffic conditions. C. Area 4 Road Maintenance Project — AE/Beshay reported that the project is in the design phase. Plans and specs will be completed within the next two weeks with construction to begin in July. May 12, 2016 PAGE 4 T&T COMMISSION D. Willow Heights Construction Update — AE/Beshay stated that this update concerns the Diamond Bar Boulevard/Brea Canyon Road enhancement project. Bid opening was held Thursday, May 5th and staff received five (5) bids. The lowest bidder is Beador Construction Company, with a total bid of $436,700. Staff will begin checking the proposal to verify the responsiveness of this bid. Bid award is scheduled in June, with construction to commence in mid-July. E. Lemon Avenue Interchange Project — SCENoung indicated that staff expected to receive the RTL by the end of April; however, Caltrans made changes to the electrical standards as late as April 15th, which requires the plans to be updated to the new standards and specifications. As a result of the additional work required to meet the current standards, staff expects it will delay the RTL until the end of May, with construction proposed to commence within the next six months. F. SR -67/60 Confluence Project— SCENoung reported that the westbound on- ramp Phase I continues to be under construction, moving toward completion next summer. Staff continues to monitor traffic along Grand Avenue and Golden Springs Drive to ensure that phasing and striping changes minimize traffic impacts. Construction of the westbound off -ramp is scheduled to begin by September/October once funding paperwork is in place for the TIGER grant. Once in place, money can be authorized to allow staff to go out to bid and award the contract. Chair/Pechy noticed a number of detour signs along Golden Springs Drive and asked if they were related to this project. SCENoung reiterated that when the ramps are closed for this project, there will be detours along Golden Springs Drive within the City of Diamond Bar. These closures are sporadic and the City is notified prior to closure of the ramp being approved by Caltrans, at which time the detour ramps will be uncovered. Detours are permitted only at nighttime and during the day the signs are to remain covered. VC/Mehta stated that he has seen a good deal of backup on southbound Grand Avenue in the evening and asked how this was impacting the City's traffic. SCENoung explained that the backup is due to the striping at the existing off -ramp intersection, which has combined the left -turn pocket with the through lane which requires split -phasing and limits the number of cars that can go through the intersection. It has not affected the Diamond Bar roadways; however, it has significantly affected southbound traffic coming from the cities of Walnut, Industry and beyond. Unfortunately, as long as this Caltrans timing scenario is implemented, there will be some congestion. This is a temporary situation during construction until next summer. G. TR 63623 — South Pointe Residential Development — SCENoung stated that infrastructure improvements of storm drains and sewer grading continues and is nearing completion. Recently, the City Council accepted the park dedication from the school district for a public park on Larkstone Drive as part of this project. The developer is responsible for constructing the park and staff is currently in the final stages of reviewing the park improvement plans so that the developer can begin construction, which they expect to complete prior to May 12, 2016 PAGE 5 T&T COMMISSION the opening of the model homes. In addition, the City Council accepted dedication from the school district for Larkstone Drive between the school and the property, which will be dedicated as a public street and will provide the only access for the park. Chair/Pechy asked if the roadway would also- be an access road for residents. SCE/Young responded that Larkstone Drive will be the primary access for residents. As one travels down Larkstone Drive toward South Point Middle School, the first access will be toward the residential development and immediately before reaching the school at the cul-de-sac will be the park access. H. Grand Avenue/Golden Springs Drive Intersection Improvements Update— SCE/Young pdate—SCENoung shared that staff continues to work with the City of Industry on the design of this intersection, as well as work with the landscape architect to provide enhancements to the intersection similar to what was done at Grand Avenue and Diamond Bar Boulevard. I I. Morning Canyon Road Rehabilitation Project — AE/Bes hay reported that the project will be advertised within the next few weeks, with the bid opening scheduled in June. The bid award is scheduled for a City Council meeting in July. VI. SCHEDULE OF FUTURE CITY EVENTS: As stated in the agenda. Chair/Pechy noted that on May 17th, the City Council will honor retiring Supervisor Don Knabe and that the next Traffic and Transportation Commission meeting is scheduled for Thursday, June gth. ADJOURNMENT: There being no further business to come before the Traffic and Transportation Commission, Chair/Pechy adjourned the meeting at 7:35 p.m. The foregoing minutes are hereby approved this day of 2016.
