BACKGROUND
In December 2019, the City of Santa Clarita (City) executed a funding agreement with the Los
Angeles County Metropolitan Transportation Authority (Metro) after obtaining Measure R grant
funds for the design of the Sierra Highway Traffic Signal Interconnect and Adaptive System
project. This project will provide a design to integrate the traffic signals along Sierra Highway,
from Dockweiler Drive to Whispering Leaves Drive, into the City's Intelligent Transportation
System to provide coordinated signal timing along Sierra Highway. This project is a joint effort
and collaboration between the City and the State of California Department of Transportation
(Caltrans).

Packet Pg. 132
As an alternative to the State Route-14 freeway, traffic on Sierra Highway increases when the
freeway is congested, significantly impacting the signalized intersections. This project will create
a design that will provide fiber-optic network redundancy along Sierra Highway that will link the
signals along that route to the City's and Caltrans' Intelligent Transportation Systems (ITS). The
design will also include measures to ensure that the system would continue to function without
any disruption even during times when there is a break in one segment of the fiber optic cable
link. Additionally, the project design will include traffic signal modifications, left -turn lane
extensions and median modifications, new generation traffic signal controllers, dynamic lane
operations, and various intersections and street improvement solutions to enhance safety and
increase traffic flow, particularly during peak commute hours.
This project is an example of Santa Clarita's commitment to utilizing technology to improve
mobility. This project supports the Building and Creating Community theme of the City's five-
year strategic plan, Santa Clarita 2020.
A Request for Proposal (RFP) for design services was advertised on the City's website on
April 13, 2020. The RFP solicited firms to identify their relevant experience in similar projects
and demonstrate their design approach for this project.
On May 20, 2020, three firms submitted proposals. Staff reviewed the proposals and based on
their evaluations, scored the submitted proposals on a 100-point scale.
Rank Company Score
1 Kimley-Horn and Associates, Inc. 95.3
2 Iteris, Inc. 87.6
3 TransCore, LLC 81.0
The scoring system heavily emphasized the understanding of the following: scope and approach
to the required work; key development items; potential issues and resolutions; the consultant's
previous experience with similar projects and experience working with the City; qualifications of
the project team and their resources; and organization of the proposal. Additionally, each firm
was asked to provide detailed hours and the scope of work required to prepare the plans,
specifications, and engineer's estimate.
The top firm, Kimley-Horn and Associates, Inc. (Kimley-Horn), demonstrated an in-depth
understanding of the project needs and provided a detailed scope of work and approach to the
project. Kimley-Horn analyzed the existing streets and identified key design factors that will
need to be addressed in the design. Kimley-Horn was previously hired by the City to design
multiple phases of the City's ITS program and has established good working relationships with
City staff.
Based on their design experience on previous City traffic projects and the completeness of their
proposal for this project, staff recommends the City Council award the design contract to
Kimley-Horn.
The requested contingency will cover any unforeseen modification, coordination with Caltrans,

and additional work required by the City.
California Government Code 4526 prescribes the selection of architectural and engineering
services to be based on demonstrated competence, professional qualifications necessary for the
satisfactory performance of the services required and does not authorize the selection of a
professional architect and engineering services based on cost. City staff negotiated a fair and
reasonable price with Kimley-Horn.
ALTERNATIVE ACTION
Other action as determined by the City Council.
FISCAL IMPACT
Upon approval of the recommended actions, adequate funds will be available in expenditure
account C0060270-5161.001 (Measure R Highway Operational Improvements) to support this
recommended contract and project administrative costs.

Kimley-Horn will prepare Final Plans, Specifications, and Opinion of Probable Cost Estimates for the City of Santa Clarita's Sierra Highway
Traffic Signal Interconnect and Adaptive System Project. The following detailed scope of work with tasks and subtasks is anticipated to
complete the project.
S dIIIbt IIk III IlFlii IId I',IeVjew
1 Senior -level traffic, civil, and ITS engineers of Kimley-Horn, experienced in completing projects through the construction stage, will perform
field analysis of the project intersections. Kimley-Horn will conduct a field visit and review the existing traffic signal equipment, interconnect
systems, and roadway to conform to current California MUTCD standards and Standard Specifications and Plans for Public Works
Construction (Green Book).
Kimley-Horn will conduct a field visit of the project area to identify potential design conflicts and constraints. Our team will prepare a
photo log documenting existing cabinet controller equipment and hardware, signal equipment, signal standards, line of sight, and existing
electrical service. Photos of utility equipment, fences, walls, sidewalks, driveways, or any other constraints that may interfere with the
proposed improvements, both along the segment and at intersections, will be provided.
2 Kimley-Horn will obtain readily available improvement plans (traffic signals, interconnect, signing/striping), aerial photos, signal timing
sheets, and right-of-way mapping from the City and Caltrans.
3 Kimley-Horn will notify the utility owners with facilities within the limits of the project. Contact information for utility owners will be provided
by City staff. We will request locations for existing and proposed underground and overhead utilities, including high -risk utilities. Kimley-
Horn will provide coordination interface to establish controls for utilities that would be included within the right-of-way limits and identify
existing underground and overhead utility lines that may interfere with the location of the proposed ITS field element equipment.
Our team will compile the information in a matrix to include dates of notification, person/utility notified, and responses from utility
departments. Copies of this information will be updated and provided to the City.
4 The Kimley-Horn team will perform a field survey from 100 ft south of the intersection of Sierra Highway and Placerita Canyon Road to
1000 feet north of SR 14 ramp exit. The topographic survey will consist of ground elevations collected at 50-foot cross section intervals
throughout the project site. The survey will be provided with contour intervals of 1-foot. Elevations will be obtained along the edge of
pavement, top of curb, flow line, gutter edge, edge of sidewalk, back of walk, and right-of-way/property line. The survey will consist of
elevations and/or locations of above ground utilities, trees (4-inch diameter at breast height and greater), ditches/swales, as well as
signing, fences, building exterior walls, and striping features. Readily visible surface indications of buried utilities as well as utilities shown
on readily available municipal utility maps provided by the City will be located and plotted on the survey.
The surveys will be tied horizontally to the California State Plane coordinate system (NAD83) and based upon existing centerline
monumentation. Vertically to the Los Angeles Public Works benchmark network (NAVD 88).
We will establish/identify local control at each survey location to assist during the construction phase of the project. A final project control
report will be made available to the City.

The City of Santa Clarita staff will collect 24 hours of turning movement counts, pedestrian counts, and bicycle counts for a single typical
weekday (Tuesday/Wednesday/Thursday) and 24 hours on a single Saturday or Sunday using the collection and analysis process of Miovision
technologies at the following locations:
II Sierra Highway/Newhall Avenue
2 Sierra Highway/Dockweiler Drive
3 Sierra Highway/Placerita Canyon Road
4 Sierra Highway & SR-14 SB On -Off Ramp
5 Sierra Highway & Kay Drive
6 Sierra Highway & Golden Valley Road
'7 Sierra Highway & Rainbow Glen Drive
4 Sierra Highway & FriendlyValley Parkway
2 Sierra Highway & Whispering Leaves Drive
The result will be uploaded by Miovision to the City's online portal for review and viewing.
Kimley-Horn will prepare a traffic analysis to evaluate three options:
(')Ilptlloin 'II This option will restrict all left -turn movements at the SR 14 on/off Ramp and will divert vehicles entering the freeway to the
intersection of Sierra Highway and Placerita Canyon Road, where the roadway will open up to two left -turn pockets, one of which being a
designated Freeway Only Lane. For vehicles exiting along the southbound SR 14 and seeking to continue south along Sierra Highway, they
will be able to make a U-turn at Sierra Highway.
(')Ilptlloin 2, This option will analyze extending the median along Sierra Highway to only allow for the left -turn movement from the SR 14
southbound off -ramp onto Sierra Highway. The existing SR 14 on -ramp at the intersection of Sierra Highway and Placerita Canyon Road
will include the same improvements proposed in Option 1 to mitigate for the closure of the SB on -ramp.
(')Ilptlloin & This option will analyze converting the intersection of Sierra Highway and southbound SR 14 on/off-ramps to a signalized
intersection and allowing for left -turn movement from SR 14 off -ramp into Sierra Highway.
The following scenarios will be evaluated for each of the three options to prepare the traffic analysis Technical Memorandum:
0Existing conditions (2020)
0Opening year conditions
0Opening year plus project conditions
0 Future year plus project conditions (2040)
0Conduct intersection level of service (LOS) analysis per the
Highway Capacity Manual (HCM) methodology.
0Weaving analysis
