AGENDA REPORT �F t�� �"
C ='I'Y OF MOORPARK _ �?
TO: The Honorable City Council.
FROM: Kenneth C. Gilbert, Director of Public Works
DATE: February 3, 1995 (Council Meeting 2- 15 -95)
SUBJECT: Consider a Project for the Construction of Modifications
to the Traffic Signals at the Intersection of High Street
& Spring Road and the Intersection of Los Angeles Avenue
& Tierra Rejada Road
DISCUSSION
A. Background
The Transportation and Streets Committee has discussed the
desirability of constructing certain modifications to the
traffic signals at the subject intersections, for the purpose of
improving traffic flow and driver convenience. The proposed
Scope of Work for these traffic signal modifications is
generally described as follows:
1. High Street and Spring Road: Placement of an overhead
internally illuminated street name sign on the mast arm
located at the northeast corner. The sign copy shall read as
follows:
High Street
Los Angeles Avenue
2. Los Angeles Avenue and Tierra Rejada Road: The installation
of one or more RIGHT TURN ARROW(S) for north -to -east right
turn traffic, to operate coincidentally with the existing
east -to -south LEFT TURN arrow.
B. Estimated Construction Cost
Staff solicited informal bids
received from Taft Electric.
work is as follows:
High Street and Spring Road:
Los Angeles Avenue and Tierra
sig_me
for this work. Only one bid was
The price quoted to perform this
$1,280
Rejada Road: $2,880
Total $4,160

C. Encroachment Permit Requirements
Both of these traffic signals are owned by Caltrans. It will be
necessary, therefore, for the City to obtain an encroachment
permit from Caltrans to perform the work. One of the
requirements of the permit is that a project design be prepared
for the desired traffic signal modifications. Caltrans requires
that the design be prepared by a Cal.trans' approved traffic
signal design engineer.
D. Request for Proposals (RFP)
Staff prepared and distributed an RFP to six traffic engineering
firms requesting that they submit Proposals for the required
design work. The list of firms which received the RFP is as
follows:
• Associated Transportation Engineers
• Signal Maintenance Inc.
• Linscott, Law & Greenspan
• WPA Traffic Engineering
• Dwight French & Associates
• ASL Consulting Engineers
• Boyle Engineering
The scope of work set forth in the RFP required 1) an
investigation phase to evaluate the existing traffic signal
installation and determine that the desired modifications were
feasible; and, if determined feasible, 2) the preparation of a
design for the fabrication, procurement and installation of the
required hardware improvements, which would meet the
requirements of Caltrans.
E. Proposals
Proposals were received from two firms. Both firms appear to be
qualified to perform the work. The fee quotations from each
firm are summarized in the Chart attached as Exhibit 'S'.
Should the City Council wish to proceed with this project, Staff
would recommend the selection of WPA Traffic Engineering, Inc.
The fee quoted by that firm is $10,750.

1. High St. & Spring Rd.: The design costs for this project are
almost twice the cost of the fabrication and installation of
the subject sign. Upon relinquishment of Spring Road to the
City, Caltrans approval will no longer be required. It is
recommended, therefore, that this modification be deferred
until after this traffic signal is relinquished to the City.
2. Tierra Rejada Rd & L. A. Ave.: The design for this project
is almost three times the estimated cost of construction.
One of the conditions of approval for PC -3 requires the
developer to modify this traffic to add North -south Left turn
arrows when and if warranted by a Traffic Study. It is
recommended, therefore, that the subject traffic signal
modification be deferred and included in that future traffic
signal modification project
RECOIIIENDATION
It is the recommendation of staff that the subject traffic signal
modifications be deferred at this time.
