ITEMS FROM COMMISSIONERS: PWD/Liu stated that at the last meeting several Commissioners brought up issues and observations to which staff would like to respond. VC/Pincher asked staff to look at the feasibility of a left -turn arrow at the Von's driveway off of Diamond Bar Boulevard. The City has certain criteria it must follow during signal warrant surveys. Based on the existing conditions, traffic volumes from the two shopping centers do not meet the warrant criteria for a left -turn signal. Staff is looking at a possible timing change as an alternative solution. VC/Pincher suggested pavement markings to indicate correct traffic movement directions from both shopping centers. PWD/Liu said that staff would discuss the recommendation with the property owners. PWD/Liu responded to C/Lin that the Golden Springs Drive traffic signals and Grand Avenue SR 60 on/off ramp signals are not interconnected because the on/off ramp signals are state-owned and the Golden Springs traffic signals are City owned. The City's Traffic Engineer confirmed that the signal at Grand and Golden Springs is running on a cycle that is 1 '/2 times the length of the onramp signal which means that City's signals are coordinated with Caltrans signals every other cycle length. PWD/Liu responded to Chair/House that the signals along Diamond Bar Boulevard, from 9:00 a.m. to 3:30 p.m., on weekdays have green phases along the corridor so that more time is allocated to side streets based on residential needs. PWD/Liu responded to C/Carrera that the reason for the short green phase eastbound on Maple Hill at about 5:30 is very likely due to the signal transition from free mode to coordinated mode to adjust to the additional traffic volume needs on Diamond Bar Boulevard. C/Lin said he observed that on Diamond Bar Boulevard near the SR60 interchange north of Kmart, when vehicles turn right out of the gas station they quickly have to merge left to get out of the right turn lane and he asked if Caltrans could combine the right -turn lane and through lane. If there is no room, there should be some kind of advanced warning so that people who turn out of the gas station know immediately that they are entering a right -turn only lane instead of a through lane. PWD/Liu responded that staff brought this matter to Caltrans attention a few years ago and staff will revisit the issue with Caltrans. VIII. INFORMATIONAL ITEMS: A. Diamond Bar Boulevard Median Modification - AE/Molina reported that this project involves the realigning of medians to improve the line of sight for vehicles making left turn movements in both directions at Diamond Bar Boulevard just north of Montefino. The bid opening for this project was held on Thursday, June 3. A total of eight bids were received with the apparent low bidder being Elite Companies US Inc. with a bid of $54,843.50 while the engineer's estimate was $66,900.

D. Industry's Grand Avenue Bridge Widening/Interchange Project — PWD/Liu stated that staff is still working with Industry's consultant to look at the travel demand forecast. Yesterday staff met with the new Caltrans District 7 Director, Mike Miles to update him on current projects. ( E. SR57/60 Feasibility Study—PWD/Liu explained that staff met with Metro. The final draft has not been given to the two cities due to current year budget concerns.

RJ Noble Company is the apparent low bidder with a bid of $908,712. The engineer's estimate was $999,000. Staff anticipates taking an Award of Contract to Council on June 15 for consideration. I. NTMP — Maple Hill Road, Cleghorn Drive/Gold Nugget Avenue, Briar Creek Road/Decorah Road Neighborhoods — AE/Molina stated that staff has not received a petition for the Maple Hill Road neighborhood to install the centerline striping proposed to the residents. Cleghorn Drive/Gold Nugget Avenue speed cushion construction is anticipated to begin on Monday. All residents have been notified. Construction is anticipated to be completed by the end of the week. Staff conducted a meeting for the Briar Creek Road/Decorah Road neighborhood in April. Subsequently, staff collected the traffic data and the data is currently being analyzed by staff and the City's JUNE 10, 2010 PAGE 4 T&T COMMISSION consultant to determine a potential concept plan to address the residents' concerns. J. Traffic Signal Maintenance Services Contract—AE/Molina reported that staff circulated an RFP for this contract in April. Two proposals were received and evaluated and based upon the qualifications presented in the proposal, staff selected Republic ITS, the City's. current signal maintenance contractor for a new three-year contract. K. FY 2010-2011 Adopted CIP Budget (Attachment A) — Receive and File. PWD/Liu reported that there are four categories under next year's Goals and Objectives: Traffic Mitigation, Fiscal Responsibility/Economic Development, Communications and, Other Items. VC/Pincher asked about "Monitor and Evaluate the NTMP Solution." PWD/Liu responded that for the past two or three years, staff has budgeted $200,000- $300,000 for the NTMP, and this year we proposed an amount of $65,000 for FY 2010-2011. Fundamentally, Council and staff support this program but this program requires commitment from the residents as well as a collaboration process to be successful. VC/Pincher said she understood the need for budget reduction and reiterated her feeling that this was such an important program for the residents of D.B. IX.

This is a medium to high cost tool. PROS 1. Good temporary public relations tool. 2. Serves to inform the public that speeding is undesirable behavior for which there are consequences. CONS 1. Effects are not permanent. 2. Enforcement is an expensive tool. Residents actively make notes of speeding vehicles and warning letters are sent to owners by Agency staff. City of Diamond Bar Neighborhood Traffic Management Program PERMANENT This is a program that allows residents to alert drivers of excessive speed without the risk of citation. The system requires active community support to be effective. The neighborhood association activates the program. When a speed issue is identified, pertinent information is collected by volunteers. PROS 1. Results in slight reduction in speeds. 2. Community becomes involved in problem identification and solution. CONS 1. Minimal effectiveness when device is removed. 2. Minimal long-term impact on travel speeds. � m M City of Diamond Bar Neighborhood Traffic Management Program ILIWFUKAKT PERMANENT A speed cushion is a variation on a standard speed hump. They taper off at the edges.

Potential to reduce traffic speed. 2. Reduces traffic volumes. 3. Can be used to reduce cut -through traffic. 4. Self -enforcing. 5. Minimal impact to on -street parking. 6. Minimum maintenance. 7. OK for emergency vehicles. CONS 1. Care needed if placed on transit routes. 2. May transfer problems elsewhere. 3. Not aesthetically pleasing. 4. May cause vehicles to encroach into bicycle lanes. Where are these located in Diamond Bar? *Sunset Crossing Road *Palomino Drive *Jubilee Lane *Castle Rock Road M City of Diamond Bar Neighborhood Traffic Management Program TEMPORARY PERMANENT Raised islands are installed along the center of the street to narrow the travel lanes in each direction. They can be landscaped to improve the aesthetics of the location and can have a built in pedestrian refuge when placed in conjunction with a mid -block crosswalk. Parking may need to be removed along the affected roadway section. Bicycle users may feel more vulnerable on narrower lanes PROS 1. Results in reduction in speeds 2. Enhances pedestrian environment. 3. Helps safety when used on curved roads by reducing speed. 4. Can be evaluated on temporary basis first. 5. Can be landscaped and made into a "Gateway" feature. CONS 1. May result in loss of on -street parking. 2. Moderately expensive measure if landscaped. 3. Center islands may be hit at night unless well marked. 4. Reduced lane widths not favored by bicycle users. Where are these located in Diamond Bar? W07•u i. 11=_ *Prospectors Raod i ME =r�lr City of Diamond Bar Neighborhood Traffic Management Program Striped parking lanes added to the roadway top reduce the effective width of the traveled way. This helps to reduce traffic speeds. PROS Where is this located in 1. Low cost measure. Diamond Bar? 2. Effective speed reduction technique. *Prospectors 3. Can be used on sloped roadways. 4. No loss of parking *Sunset Crossing Road CONS *Cliffbranch 1. Requires at least 40 foot roadway. City of Diamond Bar Neighborhood Traffic Management Program Traffic safety campaigns for a particular neighborhood usually consist of leaflets, fliers or letters sent out to residents and schools.
