PANTERA DRIVE NEIGHBORHOOD TRAFFIC MANAGEMENT PROGRAM � ( NTMP ) . o .y N AE/Malpica presented staff's report and recommended that the Traffic and � Transportation Commission receive public comments regarding the proposed � Pantera Drive NTMP . � �e Ste hanie Lubian , 823 Rexford Court, stated that not onI ~ p y is speeding a problem , but in her opinion , the signage will not help at all because 90 percent a of the traffic on Summitridge Drive and Pantera Drive run the stop signs . o, Erica Ramirez , 674 Pantera Drive , said that her street is curved and children �;, crossing the street are in jeopardy because drivers flying down the street do ; not have a clear line of sight. In the evenings , the park is extremely busy and � vehicles are coming down Pantera Drive at increased speeds . She also does �, not believe signage will help . This is a growing community with an elementary � school and lots of traffic. � Candi Holden , 608 Sky Court , has back injuries and finds it difficult to drive on o streets with speed humps . If the problem is speeding and stop signs , this is a w law enforcement issue . She would favor increased patrol in the area instead of � parking humps . In addition , it might help for the school to have a crossing � guard . � � Rhonda Mekhail , 909 Pantera , asked for speed humps several years ago due ~ to speeding traffic and failure of drivers to stop at the stop signs. She felt that d a crossing guard would not help , nor would blinking lights or signage . Ms . r Mekhail feels speed humps are important and she was told years ago that they � would impede safety vehicles and fire trucks from being able to get to the a school in time , in case of an emergency . She is thankful this program has been initiated because she cannot let herchildren playoutside forfeartheywill be hit by a car. PacketPg . 14 1 .B.a ' SEPTEMBER 12, 2019 PAGE 4 T&T COMMISSION A speaker asked for statistics on the speed humps on �eyland Drive and wanted to know if they had made any changes in traffic behavior. PWD/Liu explained that the speed humps were done as a pilot project and ;, ultimately, staff determined that speed cushions were just as effective , which N slows traffic. Staff concluded that speed humps were not something that N should be done in Diamond Bar and as a result, guidelines and tools were established for the NTMP , one of which was the speed cushions . They are E constructed with the spacing to accommodate the service vehicles to respond d within their requirements. d � AE/Malpica stated there is a difference in design between speed humps, speed o bumps and speed cushions . As PWD/Liu explained , the speed bumps and d speed humps are based on different heights and extend the entire width of the � street. Speed cushions have divisions between them to allow emergency � vehicles to pass through unimpeded . With the NTMP guidelines , the City is no c longer considering gutter to gutter speed humps and speed bumps . d Adam Tran , 751 Pantera Drive , (next door to Pantera Elementary School) , o asked if there would be follow-up meetings after tonighYs discussion . He is •y disappointed that more families (from the affected area) are not participating •� this evening . It is a challenge to get people to open their doors to discuss this o program because he and his wife went door to door in their neighborhood � attempting to promote tonighYs meeting . Mr. Tran 's number one concern is F speeding , which is something he and his wife observe in the morning when — they leave to drop their kids off for school and in the middle of the day when � parents pick up their kids . It is not only that people are speeding , many � parents park across the street from the school waiting to pick up their kids and °,' the kids tend to rush across the street to get to their parents . Heading north d down Pantera Drive , there is a blind spot and he has observed parents rushing � across the street to prevent the kids from being hit. He spoke to the principal � of the elementary schooi last year but has not spoken with the new principai . c His wife spoke with the new principal and was told the school had been trying �� for years to get a crosswalk for the parents and students . From 6 p . m . to 10 � p . m . there are young people speeding out of the park and up and down the o street. y Trichia Tran , 751 Pantera Drive , said she was the person who initiated this o process . When she and her husband were going door-to-door, they � encountered a big language barrier. Many residents speak Chinese or � Mandarin and her husband speaks neither. Also, many residents did not want ~ to answer the door or, if they did , they answered it by yelling at her and telling d her to get off of their property through their doorbell security system . t Therefore , Ms . Tran and her husband began walking together with their � children and encountered a problem with dogs rushing out of houses and going a for her baby in its stroller. There is quite a curve on Pantera Drive and , as a stay-at-home mom , she has a view from her bedroom window of the entire street and said that for her, it is more about speeding than traffic and quite often , cars speed right through the stop signs . A couple of Ms . Tran's goals led to her initiating this program : 1 ) A speed bump to help slow traffic going PacketPg. 15 7'.B.a ' SEPTEMBER 12, 2019 PAGE 5 T&T COMMISSION down Pantera Drive to Bowcreek Drive at the curve where the elementary school ends , and 2) protection for families trying to cross the street to take advantage of programs in the park. In addition , there are skateboarders that come to the area at about 3 :00 a . m . who start at the top of the hill , hang onto � the back bumpers of cars and let go to speed down the hill . She feeis the N speed humps will help in this instance as weli . She wished the signage wouid � help but does not believe it will . ;, a Richard Young , 675 Bowcreek Drive , shared he has called the Sheriff's d Department and sent them an email to let them know that, as a neurosurgeon d he sees trauma with high speed injuries and kids getting hit. He has a 4-year �' oid and 2-year old and does a lot of yard work out in front of his home and �°, since sending the email he has noticed an increase in police presence . The ; issue is that everyone is rushed and everything people have said happens on a `- daily basis because of all of the activities at the park. Safety is number one o, and when his 2-year old ran out into the street to retrieve a ball , he felt that was � the last straw and he needed to take action . He believes speed bumps and � street narrowing are a great deterrent. However, with all of the street parking , o the street is narrower and it is already essentially a two-lane street. Fire •y Station 121 is just down the hili and he did not believe speed humps would E appreciably delay them in getting to Pantera Elementary. Another option is o speed dips which he has seen in the City of Los Angeles . � � Larry Holden , 608 Sky Court, stated that he concurs with everything that has � been said and the bottom line is that traffic needs to be slowed down on o, Pantera Drive . As previously stated , speed bumps will be an issue for his wife � as they have already changed their path of travel from �eyland Drive to ;, Summitridge Drive . He felt that enforcement could be increased and asked if it y costs more for the City to ask for patrols on Pantera Drive and whetherthe City � has input on where the Sheriff's Department patrols . � VC/Gonzalez indicated that when the Sheriff's Department receives a c complaint and the City makes a complaint directly to the Sheriffs Department, �� a patrol request is forwarded to the department and the units working that area � pick those up on a daily basis . o N Mr. Holden continued that people are saying signage will not work ; however, � he agrees there should be a crosswalk at Pantera Elementary School and o another stop sign between Rexford Court and Bowcreek Drive at the � crosswalk, including increased enforcement. � � C/Quan added that she understands the speakers' concerns . She was a � principal at Golden Springs Elementary and at Ranch Oaks and she witnessed � instances of drivers that did not follow signage . Even with a crossing guard , � there continues to be moments of anxiety. The crosswalk heips ; however, does Q not completely deter any speeding . The best thing is education and enforcement presence . C/Quan shared that every time she requested enforcement presence ; drivers behaved themselves. Once the Sheriff's car moved out of the area , they returned to their old habits . Packet Pg. 16 1 :Ba SEPTEMBER 12, 2019 PAGE 6 T&T COMMISSION PWD/Liu reminded the Commission and the audience about the process the City must take in this effort. TonighYs meeting is an introductory meeting , the purpose of which is to gather additional input from residents . Staff has been in conversation with some of the residents over the past few months . In addition , � increased enforcement and additional signage were implemented on that N stretch of Pantera Drive . It is clear that whatever is agreed upon has to be � done through this consensus building process , which means that staff will a continue with outreach to the residents. Ultimately, in order to be successful , � the majority of the residents will need to support the traffic calming devices . g Bottom line, with respect to speeding , the only permanent solution that would v� help address that issue would be the speed cushions . However, in order to 0 implement speed cushions , certain standards have to be met. Also , everyone a needs to keep in mind that they will be permanent roadway features, which can � only be reversed through this same process and approved by a majority of � affected residents . Staff sent out about 170 letters inviting people to tonighYs � meeting and only about 10 are present. Based on past experience , however, ; tonighYs turnout is good , but there needs to be a continuing outreach effort. � Crosswalks and stop signs will not work. Stop signs are traffic "regulatory" o signs and are not meant to slow down traffic, but are designed and enforced to y make sure there is proper traffic assignment (orderly movement of vehicles � through intersections) . Without the presence of law enforcement, people will � continue to roll through the stop signs . There will also need to be a dialogue � with the school officials . r PWD/Liu added that staffwill continue reaching out to residents . This program °' was initiated after stafftalked with Mr. and Mrs . Tran . All stakeholders have to � participate in this effort. This could be a phased or incrementai approach . °,' Staff wili continue to work with the Sheriff's Department to make sure they are d present; however, they cannot be on-site 24/7 . There is a dedicated black and � white that visits each of the schoois on a rotational basis . PWD/Liu believes � the school district can play a very important part by educating parents and � understanding what they need to do to create a safe environment for the �� students . � � Chair/Garg thanked residents for their participation .
