punch list of items for the striper to install striping where it was missed and fix
substandard striping. In particular, the thermal plastic signal head legend on
the southbound lanes of Diamond Bar Boulevard between Kmart and Golden
Springs Drive is substandard and must meet City standards. Today, staff met
with the designers for the design of Residential Area 4 and Arterial Zone 2 with
work planned for next summer.

on interpreting the final traffic counts taken in June and staff is planning to

forwarded to the consultant to prepare for a neighborhood meeting prior to the
Thanksgiving holiday.
J. Prospectors Road Rehab Project — AE/Molina stated that at its October 2"d
meeting, the City Council awarded the contracts for this work. Staff decided to
postpone the project until after the first of the year, so as not to disrupt
residents during the holiday season.
SE/Yee responded to C/Pincher that the study session was scheduled to commence
at 5:00 p.m. with another agenda item preceding the Industry's Grand Avenue Bridge
Widening/Interchange Project item.
VC/Mok stated that a resident approached him and asked if the phasing of the signal
at the intersection of Golden Springs Drive/Diamond Bar Boulevard was permanently
set or if staff would study the traffic flow for possible adjustments (Item B). SE/Yee
responded that there have been calls about the timing at Brea Canyon Road/Golden
Springs Drive and at Golden Springs Drive/Diamond Bar Boulevard intersections.
During the switchover from in -pavement loop detection to video detection, the signal
had to be put on recall. In about a week this will be corrected.
