Amount Budgeted: $500,000
Additional Appropriation: N/A
Account Number(s): 215-400-8828-8005
ORIGINATED BY: Nadia Carrasco, Assistant Engineer
REVIEWED BY: Elias Sassoon, PE, Director of Public Works
APPROVED BY: Doug Willmore, City Manager
ATTACHED SUPPORTING DOCUMENTS:
A. Willdan’s Proposal for Design Services (page A-1)
B. Amendment No. 1 (page B-1)
BACKGROUND AND DISCUSSION:
On October 22, 2018, the Traffic Safety Committee (TSC) discussed and reviewed, as
part of its working plan for this fiscal year, the traffic signal warrants that were
conducted and met for the intersections of Hawthorne Boulevard & Via Rivera, and
Palos Verdes Drive South & Palos Verdes Drive East. The warrant studies were
completed in 2014 and 2017. W illdan Engineering indicated that the warrants are still
valid, and thus, no re-evaluation is needed.
The traffic signal warrant study for the intersection of Hawthorne Boulevard & Via Rivera
was conducted and included as part of the City of Rancho Palos Verdes General Plan
Update, Traffic Impact Analysis of May 2017, prepared by Translutions, Inc.
1
The traffic signal warrant study for the intersection of Palos Verdes Drive South & Palos
Verdes Drive East was part of the Palos Verdes Drive South Traffic Report, prepared by
Willdan Engineering in November 2014.
Based on the studies previously performed by these two traffic engineering consulting
firms, the Traffic Safety Committee directed Staff to forward a recommendation to the
City Council to consider the preparation of the engineering design plans for the traffic
signal lights at these two intersections. The design fee for engineering design services
for the traffic signal design at Hawthorne Boulevard & Via Rivera intersection is
$18,818, which will include the synchronization with the traffic signal lights along
Hawthorne Boulevard. The design fee for the Palos Verdes Drive South & Palos
Verdes Drive East intersection is $15,780. It is estimated to complete the engineering
design for these two intersections within a 6 month period.
Authorization to Amend the existing contract with Willdan to perform this work was
approved by the City Council at the July 31, 2018 meeting (Attachment B). The
estimated construction costs for the installation of the traffic signal lights are $200,000
for the Hawthorne Boulevard & Via Rivera intersection and $250,000 for the Palos
Verdes Drive South & Palos Verdes Drive East intersection.
ALTERNATIVES:
In addition to the Staff recommendation(s), the following alternative action is available
for the City Council’s consideration:
1. Discuss other options which may be appropriate in lieu of Staff’s
recommendation.

Subject: Proposal to Provide Professional Traffic Engineering Design Services
for the Traffic Signal Installation at Hawthorne Boulevard and Via
Rivera
Dear Ms. Carrasco:
Pursuant to the Professional Services Agreement between the City of Rancho Palos
Verdes and Willdan Engineering dated September 5, 2017, Willdan Engineering is
pleased to submit this proposal to provide professional traffic engineering design services
to the City of Rancho Palos Verdes for the preparation of plans, specifications, and
estimates (PS&E) for the installation of a traffic signal at the intersection of Hawthorne
Boulevard and Via Rivera. Hawthorne Boulevard is a synchronized corridor from Palos
Verdes Drive South to Highridge Road and the new signalized intersection falls within this
stretch of corridor and will need to be synchronized with the adjacent traffic signals.
The following is our proposed scope of work, schedule and fee:
SCOPE OF WORK
1.Meet with City staff to review specific design and construction requirements.
Obtain record drawings of striping plans, utility plans, roadway plans, street lighting
plans, etc.
2.Conduct a field investigation to verify existing topographic conditions and identify
unusual or special conditions, if any.
3.Provide utility coordination, including notices to all utility companies in accordance
with City’s procedures. All documentation of contacts and responses will be copied
to the City. Willdan Engineering will prepare utility notices and deliver them to the
City for mailing under City letterhead. If so desired by the City, Willdan Engineering
can transmit these notices under Willdan Engineering’s letterhead; however, the
City shall be responsible for any fees assessed to Willdan Engineering by the utility
companies. In either case, all responses, questions, and correspondence from the
utility companies will be addressed to Willdan Engineering’s Utility Coordinator.
