MEMORANDUM
TO: Ken Griffin, City of Co I
FROM: John Polster, ITS
DATE: February 22, 20
RE: Status Reports on SH 121
Attached are three status reports from the North Texas Tollway Authority on various issues
associated with the development of SH 121.
The first is a report on the placement of fiber optic cable along the length of SH 121. The fiber
optic installation consists of 288 strands of fiber. 144 strands will be used by NTTA for its
communication requirements. The remaining 144 strands will be made available to local
governments for their use for communications, redundancy and interoperability. It may be
advantageous for Coppell to review this offer to determine if there is a possibility of utilizing a
portion of these lines.
The second report is a briefing on the status of the Landscape Project and the construction of
pavement markings, signage and sound walls. Currently, NTTA anticipates expending about
$500,000 per mile on landscaping of SH 121. I have attached a map of the focus areas,
estimated schedule, a sample plant palate, a rendering of the typical layout at MacArthur and a
sample of the "fractured fin" sound wall form liner. Additionally, I am attaching the actual noise
wall design sheets for your review and records. These plans show the location and details of
each wall.
Finally, the third report is a progress report on the final design and construction of SH 121. The
area to review in this report is the location and particulars of the toll gantries within the corporate
limits of Coppell. I am also attaching the actual 60% plan set for your review. To the extent
that Coppell has any comments associated with the plans for SH 121, now is the time to provide
them.
I would like to meet with you once you receive this material and have had time to review it.
Should you have questions in the mean time, please do not hesitate to contact me.

EXECUTIVE SUMMARY
Landscape Project Briefing on
President George Bush Turnpike Eastern Extension
and State Highway 121
February 6, 2008
Background
• Resolutions were approved by the North Texas Tollway Authority (NTTA) Board
for work authorizations with HNTB Corporation for landscape design services on:
• President George Bush Turnpike Eastern Extension (PGBT EE) at the
June 2007 Board Meeting.
• State Highway (SH) 121 at the July 2007 Board Meeting.
• The landscape design for both projects will comply with the NTTA System Wide
Design Guidelines (SWDG), including changes currently anticipated through the
SWDG 2.0 revision process.
General Overview
• The proposed PGBT EE landscape project limits extend from SH 78 to Interstate
Highway (IH) 30. It encompasses a total of 10.28 miles including 1.38 miles
within the Texas Department of Transportation (TxDOT) section north of IH 30.
• Eight priority focus areas have been identified and design is just
beginning. After the PGBT EE roadway construction is completed, the
project will be let as a single landscape construction contract.
• A 30 percent plan submittal is anticipated for April 2008.
• Proposed landscape project limits for SH 121 extend from Business 121 in
Lewisville (Segment 1) to west of Hardin Boulevard in McKinney (Segment 3)
and covers 22.6 linear miles. The project does not include 3.3 miles within
Segments 4 and 5 at the Dallas North Tollway (DNT) and U.S. 75 interchanges.
• Fourteen priority focus areas are identified for Segments 1, 2 and 3.
• The schedule for landscape design plans and construction documents for
Segments 1 and 2 will allow landscape improvements to begin when
construction along these segments is completed.
• Landscape design plans and construction documents for Segment 3 will
occur after the landscape project letting for Segments 1 and 2.
• For Segments 1 and 2, a 60 percent plan submittal is anticipated for
February 2008.
• The extent of landscape improvements included in median areas will take into
account the timing of future widening projects. Where widening projects are
likely to occur in the short-term, landscape improvements will be located outside
of the median areas.
Budget/Future Impacts
• Landscape plans are being developed with a construction cost (current dollars) of
approximately $500,000 per mile.
• Detailed estimates will be prepared as plans progress.
Staff Recommendations
None at this time.

EXECUTIVE SUMMARY
State Highway 121
Fiber Optic Cable and Electrical Infrastructure
Award of Contract 02314-SH1 21 -00-CN-IT
February 6, 2008
Back-ground/History
• The North Texas Tollway Authority (NTTA) currently maintains a fiber optic network
infrastructure necessary for data and voice communications between facilities and
devices located throughout the Dallas North Tollway (DNT), President George
Bush Turnpike (PGBT), Addison Airport Toll Tunnel (AATT) and Mountain Creek
Lake Bridge (MCLB). This network supports the NTTA's toll collection system,
security system, Intelligent Transportation System (ITS), and voice and data
networks.
• The NTTA's ITS is comprised of Closed Circuit Television (CCTV) cameras,
Dynamic Message Signs (DMS), Travel Times sensors, and pavement sensors.
• The incident management system utilizes CCTV cameras to automatically
detect traffic accidents and incidents along the NTTA's roadways. This
system facilitates reduced incident detection and response times, which
increases mobility and traveler safety along the NTTA's roadways.
• The traffic management system utilizes travel times sensors to collect travel
data from ToIITag- equipped vehicles and provides pre -trip and roadway
travel information to the traveling public via DMS and the NTTA's public
website.
• Road Weather Information Systems (RWIS) sensors provide pavement
condition data to the maintenance department for facilities monitoring and
the coordination of the NTTA's snow and ice sanding program.
Genera! Overview
• CCTV and DMS foundations were included in the State Highway 121 roadway
design plans and are currently under construction.
• The fiber optic cable backbone will utilize existing TxDOT- installed conduit where
available.
• Current design plans specify the installation of thirty -eight CCTV camera locations,
eighteen travel time sensors, three DMS and one RWIS sensor along Segments 1
and 2 of State Highway 121.
• To facilitate continued operational efficiencies and service levels throughout
Segments 1 and 2 of State Highway 121, communications and electrical
infrastructure must be installed to support ITS devices.
• The proposed project will deploy fiber optic cable and fiber optic laterals to planned
ITS devices and ITS electrical conduit infrastructure along Segments 1 and 2 of
State Highway 121 from the south end Business 121 to Hillcrest Road.
• The fiber optic installation consists of a group of 144- strands to be used by the
NTTA for its current and planned communications requirements, as well as an
additional 144- strand grouping to be provided to regional authorities for redundancy
and interoperability.
NTTA Board Meeting — Executive Summary
Electrical infrastructure including conduit, ground boxes and junction boxes will be
installed to service ITS devices. Electrical conductor wire and transformers will be
installed by the roadway contractor.
The anticipated duration of this contract is 120 days. Substantial completion of the
installation of the ITS communication conduit system ITS electrical systems is to
occur no later than May 15, 2008, for Segment 1 and June 15, 2008, for Segment
2.
The recommended firm has indicated that they will meet or exceed the NTTA
BOPP goal of 20 %.
Budget/Future Impact
• The Engineer's estimate for the installation of fiber optic cable and electrical
infrastructure is $4.3 million.
• Thirteen proposers purchased bid documents.
• Bids and qualification information were received from potential proposers on
January 28, 2008. Five proposers submitted qualifications, of which were
determined to be qualified bidders.
