Request for Speed Humps on Goldrush Drive. DDPW/Liu presented staffs report. Staff recommends that the Traffic and Transportation Commission review and discuss the supporting speed hump documents/studies received from other municipalities. He discussed the current speed hump policies for the cities of Brea, Chino Hills, Mission Viejo, Pasadena, Santa Ana and Walnut. He explained that the City Council requested that the Traffic and Transportation Commission to again consider its previous recommendation for a "No Speed Hump" policy on a citywide basis. C/Morris stated that staffs report indicates the maximum grade recommended for speed hump installation is 8 percent. He pointed out that the report indicates that the Goldrush Drive grade is from 8.7 percent to 14.3 percent which indicates the street exceeds the general speed hump criteria. DDPW/Liu confirmed that Goldrush Drive is a steep grade. Staff recommends that if the City adopts a speed hump policy, no speed hump be installed when the street grade exceeds 8 percent because of the potential safety hazard. JANUARY 8, 1998 PAGE 3 T&T COMMISSION C/Morris stated he believes that a speed hump installation on either Goldrush Drive or on Armitos Place would serve as a "launch ramp". He reiterated his opposition to having speed humps in the City of Diamond Bar on public streets. C/Nice confirmed his previous opposition to speed hump installations in the City of Diamond Bar. VC/Virginkar concurred with C/Nice. Based upon previous discussions, he is still opposed to speed hump installations in the City. Chair/Leonard-Colby said she believes staffs thorough investigations support a "no speed hump" policy. C/Morris stated he favors investigation of alternative mitigation measures such as flashing lights for City streets that have steep grades. Sgt. Rawlings reported that during the last 12 months, three traffic collisions occurred and 154 hazardous citations were issued on Goldrush Drive which translates to an enforcement index of 77.0 for the street or twice the amount for the rest of the City. He pointed out that the January 1, 1998 law requiring school buses to engage flashing red lights when stopped to load or unload has resulted in three traffic collisions in Southern California. The law is well- meaning but has not necessarily achieved its intended goal. Following discussion of the Commission's previous decision to recommend a "No Speed Hump" policy for the City of Diamond Bar, C/Morris moved, VC/Virginkar seconded, that the Traffic and Transportation Commission uphold its previous decision to recommend a "No Speed Hump" policy for the City of Diamond Bar and requested that staff investigate alternative safety mitigation measures for Goldrush Drive. The motion was carried 4-0 with the following Roll Call vote: AYES: COMMISSIONERS: Morris, Nice, VC/Virginkar, Chair/Leonard-Colby NOES: COMMISSIONERS: None ABSENT: COMMISSIONERS: Istik VII.

These entrances now prohibit right turns from the school parking lot. The Brea Canyon Road bus ingress/egress has been opened on a trail basis as an egress for vehicles. The school has recommended modification of the Brea Canyon Road at Pathfinder Road signal light. Prior to any alterations, staff will observe the area for approximately 30 days. DDPW/Liu reported that the cross -hatch striping on the eastbound side of Grand Avenue between Montefino Avenue and Diamond Bar Boulevard was installed on December 23, 1997. City Council has asked staff to monitor the effectiveness of the installation and requested that the Traffic and Transportation Commission consider alternatives including the feasibility of a Class II bikeway installation and report back to the City Council in six months. DDPW/Liu stated that at its December 16, 1997 meeting, the City Council established an off-site parking task force headed by Chair/Leonard-Colby to identify the issues related to the prohibition of street parking for certain types of vehicles in the City of Diamond Bar. He further stated that the City Council also established solid waste standards task force to consider the AB939 requirements of whether of not the City -�-, will be able to achieve the 50 percent diversion rate and examine the current permit system for the waste haulers. VIII. ITEMS FROM COMMISSIONERS: C/Morris asked about the status of the stop sign warrant study at the T -intersection of Palomino Drive and Bellena Drive. DDPW/Liu responded that as a result of the school safety study, a number of intersections were identified for warrant study. He indicated he will report back to the Commission regarding the status of this intersection. VC/Virginkar stated that two residents requested the City investigate the traffic signal timing at Summitridge Drive and Grand Avenue. He said they are concerned that during the evening rush hours, the westbound left turn signal is too short and traffic backs up outside the left turn pocket.
