h) SB 1 Trade Corridors Enhancement Program (TCEP) 2020 Grant
Application for the SR-57/60 Confluence Relief Program –
PWD/Liu– On August 3, 2020 the LA County Metropolitan
Transportation Authority (LA Metro), in partnership with Caltrans,
submitted the grant application for the SR-57/60 Confluence Chokepoint
Relief Program Project to the California Transportation Commission
seeking $217.9 million in funding from Senate Bill 1 (SB 1) Trade
Corridors Enhancement Program (TCEP). The City of Diamond Bar
actively participated in the preparation of this application together with
Caltrans, the San Gabriel Valley Council of Governments (SGVCOG)
and the City of Industry. This project has a total cost of $420,288,000
and with 2020 TCEP funding, LA Metro will be able to begin
construction in August 2022 rather than July 2024. Diamond Bar
believes this project is a strong candidate for SB1 TCEP 2020 funding
and expects to learn of the grant decision by November 12th.

Pathfinder Road) – AE/Aoun – Plans and Specifications for a
pavement rehabilitation project on Diamond Bar Boulevard beginning

completed this month with construction tentatively scheduled for
October.

Caltrans District 7 commenced a roadway resurfacing and restoration
SEPTEMBER 10, 2020 PAGE 4 T&T COMMISSION
project along State Route 57 (SR-57) freeway (the “Project”) for
approximately 4.5 miles. The three-year project will cover both
northbound and southbound lanes along SR-57 between the Orange
County Line toward Los Angeles County, where SR-57 merges with
State Route 60 near Grand Avenue. Under California Streets and
Highways Code Section 93, Caltrans is authorized to construct and
maintain detours as may be necessary to facilitate the movement of
traffic where state highways are closed or obstructed by construction or
otherwise. The City of Diamond Bar roadways will be affected during
the Project-related traffic detours. The Project estimates 16 extended
weekend closure detours (over eight two-day weekends) for the
duration of the project, which will be scheduled to be implemented
during the low traffic hours and City Staff and traffic consultants will be
monitoring the traffic flow and adjusting the City traffic signals timing, as
needed, to ensure a steady flow of traffic during the detours. The City
and Caltrans negotiated a Traffic Detour Cooperative Agreement,
approved by the City Council at its August 18, 2020 meeting, under
which the City will be reimbursed for the traffic monitoring and signal
adjustment, as well as additional Sheriff’s services, as applicable. Per
the Agreement and upon completion of the Project, Caltrans, at its cost,
will restore the City streets impacted by the detours to their condition
prior to the detours and to achieve that goal, Caltrans, in coordination
with the City Staff, will evaluate the condition of streets before
commencement and after project completion.
k) Suspension of Street Sweeping Parking Enforcement – PWD/Liu –
At its September 1st regular meeting, the City Council approved the
suspension of parking citations for street sweeping infractions in
residential areas for the remainder of 2020. The suspension went into
effect immediately and was implemented in support of residents who
are continuing to follow state and local COVID-19 safety mandates and
are working or schooling from home. During the suspension, street
sweepers will continue to maintain their schedules and residents are
asked to move their vehicles during their neighborhood’s designated
day and time to allow for effective removal of excess debris. Street
sweeping schedules are listed on the City’s website at
www.diamondbarca.gov/streetsweeping.
