RE: PROPOSAL TO PROVIDE ENGINEERING SERVICES FOR TRAFFIC
SIGNAL MODIFICATIONS AT WALNUT GROVE AVENUE /HELLMAN
AVENUE /RAMONA BOULEVARD AND INSTALLATION OF TRAFFIC
SIGNAL AT HELLMAN AVENUE /1 -10 ON /OFF RAMPS
Attached for your consideration is an engineering proposal from Willdan for engineering
design, utility coordination, contract administration, and construction observation services
for the traffic signal modification at Walnut Grove Avenue /Hellman Avenue /Ramona
Boulevard and installation of a new traffic signal at Hellman Avenue /1 -10 On /Off Ramps.
A traffic study was recently completed analyzing the existing traffic flow at the intersections
of Walnut Grove Avenue and Hellman Avenue /Ramona Boulevard and at Hellman Avenue
and the 1 -10 Freeway Ramps. The traffic study concluded the installation of anew traffic
signal at the Hellman Avenue /1 -10 Freeway Ramps was justifiable using Caltrans traffic
signal warrant analysis. Due to the close proximity of the two intersections, it is
recommended that the existing traffic signal at Walnut Grove Avenue and Hellman
Avenue /Ramona Boulevard and the new signal at Hellman Avenue and the 1 -10 Freeway
Ramps operate as one signalized location.
The project consists of modifying the existing traffic signal at Walnut Grove Avenue and
Hellman Avenue /Ramona Boulevard to include new intersection phasing and vehicle
heads, and to install new traffic signal poles, vehicle indications and detection at the 1 -10
Freeway Ramps at Hellman Avenue. Both intersections will be connected to the traffic
signal controller at Walnut Grove Avenue and Hellman Avenue /Ramona Boulevard.
A description of the proposed traffic signal timing can be found in Exhibit "A ".

Subject: Proposal to Provide Engineering Services for Traffic Signal Modifications
at Walnut Grove Avenue /Hellman Avenue /Ramona Boulevard and
Installation of Traffic Signal at Hellman Avenue /1 -10 On /Off Ramps
Dear Mr. Tripepi:
As requested, we are pleased to be given the opportunity to submit this proposal for
installation of a new traffic signal at Hellman Avenue /1 -10 On /Off Ramps and
modification to the traffic signal at Walnut Grove Avenue /Hellman Avenue /Ramona
Boulevard.
A traffic study was recently completed analyzing the existing traffic flow at the
intersections of Walnut Grove Avenue and Hellman Avenue /Ramona Boulevard and at
Hellman Avenue and the 1 -10 Freeway Ramps. The traffic study concluded the
installation of a new traffic signal at the Hellman Avenue /1 -10 Freeway Ramps was
justifiable using Caltrans' traffic signal warrant analysis. Due to the close proximity of
the two intersections, it is recommended that the existing traffic signal at Walnut Grove
Avenue and Hellman Avenue /Ramona Boulevard and Hellman Avenue and the new
traffic signal at 1 -10 Freeway Ramps operate as one signalized location.
The project consists of modifying the existing traffic signal at Walnut Grove Avenue and
Hellman Avenue /Ramona Boulevard to include new intersection phasing and vehicle
heads, and to install traffic signal poles, vehicle indications, and detection at the 1 -10
Freeway Ramps at Hellman Avenue. Both intersections will be connected to the traffic
signal controller at Walnut Grove Avenue and Hellman Avenue /Ramona Boulevard.
SCOPE OF SERVICES
We propose to provide the following basic services for the project:

A. AUTHORIZATION TO REJECT CLAIMS AGAINST THE CITY FROM
CATHERINE AND LAWRENCE PANARELLI
B. AUTHORIZATION TO REJECT CLAIMS AGAINST THE CITY FROM
HONG BUM CHOI AND KIE SOK CHOI
Councilman Taylor referring to CC -B, asked why the claim is filed against the City when
it was the Gas Company that was doing the work.
Nancy Valderrama, City Clerk, replied that the attorney representing the claimants was
informed of that fact but insisted on filing a claim against the City nevertheless. The claim was
sent to the City's adjuster Carl Warren & Company who recommended rejection of the claim and
will ultimately tender the claim over to the Gas Company.
Councilmember Clark requested an explanation from the City Attorney on the standard
procedure of claims filed.
Robert Kress, City Attorney, explained that the City is part of the Joint Powers Insurance
Authority pool. Claims are typically referred to the City's adjuster, Carl Warren & Company,
and they routinely recommend rejection. Mr. Kress stated that this does not indicate that the
matter will not be settled in a future time. However, it does set up time parameters on the statute
of limitations in which to file a claim.
