He further stated that it was also noted that there are about 15 vacant spaces in the First Mortgage parking lot. He stated that they would recommended that the 2 -hour restricted parking remain across from ' the homes and that the red curb be extended another 15 feet to afford sight distance off of the street. He then stated that it does appear that the parking lot at First Mortgage Corporation can be easily double decked. December 16, 1993 PUBLIC COMMENTS: CONSENT CALENDAR: OLD BUSINESS: Page 2 k There were none. There were no items on the Consent Calendar. There were none. NEW BUSINESS: Striping on SE/Liu presented the staff report regarding the request made by a Mt. Laurel Way resident to investigate the appropriateness of designating turn lanes at Diamond Bar on Mountain Laurel Way at Diamond Bar Boulevard. It was Blvd. determined that the count data clearly indicates that left turns are the predominant traffic movement on Mountain Laurel Way in that the left turn volume exceeds the sum of the through and right turn movements on each approach. Striping to provide left turn lanes would improve the operating efficiency of the intersection and reduce delay. It is recommended that the Commission approve the striping of left and through lanes on the eastbound and westbound approaches of Mountain Laurel Way at Diamond Bar Boulevard and install 100 feet of red curb on the north side of Mountain Laurel— Way aure!Way between Silver Rain Drive and Diamond Bar Boulevard. Chair/Chavers opened the meeting to allow those wishing to speak to address the Commission. Deborah Renegar, residing at 1386 Rolling Knoll Road, requested clarification if the left turn lane will be designated for only left turns with the arrow. SE/Liu confirmed that the left turn arrows will be painted in the left turn lanes to be specifically designated for left turn movements, and the right curb lane will allow a shared through and right turn movements. Furthermore, signing could be implemented on the parkway portion of the street in addition to the pavement marking. Chair/Chavers expressed concern with combining through and right, particularly since the eastbound movement to go south on Diamond Bar Boulevard is a fairly substantial movement. Striping a left lane must turn left, in combination with a right and through, in this situation, would create congestion by backing up the right turn. He further expressed concern with posting a left lane must turn left type of sign on the right side of the street because it is not naturalb, seen by a motorist. Also, because Diamond Bar Boulevard it sufficiently wide, mounting a left lane must turn left sign on the mast arm may not be enough advanced warning for motorists. He stated that the solution being recommended may actually create 1 1 1 December 16, 1993 Page''3 more of a problem existing now. Chair/Chavers then suggested that the lanes be realigned by placing the left turn lanes, making the inbound lane about 16 feet, and then combining the through and the right for the delay problems. Moving the left turn lanes over a bit will thus improve visibility from left turning vehicles. VC/Gravdahl expressed concern if a week to respond was adequate for those residents affected by the red curb. SE/Liu stated that if the recommendation goes forward to the City Council, the Council would have to adopt a resolution, thus giving ample time in that respect. Additionally, staff will follow up with telephone calls or site visits to the respective properties. He then stated that the remedy being recommended here is identical to the remedy recommended for the intersection of Diamond Bar Boulevard at Cold Spring Lane, which had a similar problem, and that remedy seems to be working. C/Cheng concurred with the suggestion made by Chair/Chavers to realign the lanes to improve visibility and have a through and right lane. SE/Liu suggested that staff could review the existing condition on Cold Spring Lane and Diamond Bar Boulevard, possibly updating the traffic count information, for purposes of comparison with the situation on Mountain Laurel Way and Diamond Bar Boulevard. Moved by VC/Gravdahl, seconded by Chair/Chavers and carried unanimously to table the item to the meeting of January 13, 1994, and to direct staff to bring back the traffic counts on Cold Spring Lane at Diamond Bar Boulevard. ITEMS FROM Chair/Chavers, in regards to Golden Springs Drive resurfacing COMMISSIONERS. project, suggested that the next time such a project is undertaken, the City should embed loops right after rotomilling, followed by resurfacing so that new holes are not cut into brand new pavement and the loops are installed much quicker. VC/Gravdahl expressed concern that the ridges existing in some places where the lanes meet on Golden Springs Drive could cause problems for scooters and motorcycles. Chair/Chavers inquired why the right turn lane at Grand Ave. and Golden Springs Drive, for north bound Golden Springs Drive to go east on Grand Ave., was utilized rather than doing double -lefts or some other use of the pavement cross section. December 16® 1993 Mage 4 SE/Liu stated that the northbound Golden Springs Drive right turn lane at Grand Ave. was recommended to the City Council by staff and the Traffic and Transportation Commission. Chair/Chavers stated that the item that came before the Commission was an informational item only, and the Commission did not make a recommendation. He expressed concern that creating the right turn lane at Grand Ave. and Golden Springs Drive basically precludes any option of creating a double left from Grand Ave. to Golden Springs Drive in either direction by narrowing the two receiving lanes. It is not the best use of the pavement. He stated that double left turn lanes could have been put on Grand Ave. at Golden Springs, but it would have pushed the through traffic over into the right lane similar to what exists at Diamond Bar Boulevard. SE/Liu stated that as part of the Grand Avenue Traffic Signal Synchronization Project, Grand Avenue/Golden Springs Drive and Grand Avenue/Diamond Bar Boulevard intersections will be analyzed and modified accordingly. -- C/Cheng requested an update on the design status of the traffic signal at the intersection of Diamond Bar Blvd. and Shadow Canyon Drive. SE/Liu reported that the plans and specifications are expected to be completed in February of 1994. ITEMS FROM SE/Liu reported that the County has indicated that the existing STAFF: raised median between the two ramp terminals on Pathfinder Bridge is feasible based upon the traffic projections (to year 2008) for the left turn demands. The noses are permanent, but the section between the two noses can be removed at any given time if future demand so warranted. He then reported that staff has provided a service request to the County to install the right turn lane and the installation of those parking restriction signs as recommended by the Commission for east bound Pathfinder Road at Brea Canyon Road. SE/Liu reported that the City has sent letters to the two School Districts and all principals of the elementary schools throughout the -- City regarding the crossing guard warrant item. He then reported that the Holiday Shuttle Ridership program is being used more thar the previous years.
