The development of the SH 114 / SH 121 MIS has continued to be a very labor-
intensive undertaking in both City Staff time and our consultant's time.
City Council has previously approved a contract with Parsons Transportation Group on
June 6, 2000 in an amount of $ 52,800.00 and a subsequent Change Order in an
amount of $ 21,030.30 on March 20, 2001. A contract was awarded by the City Council
to Turner Collie & Braden, Incorporated on June 18, 2002 in an amount of $ 50,000.00
for Traffic Analysis Services in the SH 114/ SH 121 Corridor and amendments on
August 19, 2003, in an amount of $ 27,360.00, on February 3, 2004 in an amount of
$ 50,000.00 and on September 7, 2004 in an amount of $ 50,000.00.

The total contracted to date for this project is $ 251,190.30.
In previous reports to City Council, staff has outlined the history of the project and the
process that the staff and the city's consultant were pursuing to finalize the project.
The TxDOT consultant has incorporated much of the City's recommended access and
interchange configurations into the plan in a preliminary phase. We still have some
access issues that we are working on with TxDOT and their consultant, HDR.
TxDOT and NCTCOG are still negotiating their traffic volume inconsistencies in the
western portion of the corridor in the vicinity of SH 26 and FM 1709.
During these discussions with NCTCOG, the City and TxDOT, some additional access
possibilities were identified, reviewed and analyzed. These access possibilities are:
• the east segment of the corridor in the vicinity of FM 2499, SH 26, 1 -635 and Bass
Pro Drive,
• the south segment of the corridor in the vicinity of SH 121, SH 360 and Hall Johnson
Road, and
• the west segment of the corridor in the vicinity of SH 26, FM 1709 and College
Street.
TxDOT's consultant has determined that the majority of the City's access suggestions
can be constructed from a physical perspective. However, the operations of the access
scheme has yet to be simulated by TxDOT's consultant. They are waiting for final
agreed upon traffic volume projections. Once those are finalized, the consultant will
model the proposed schematic to determine the operational characteristics of the flow
during the design hour and identify areas of undesirable congestion.
Our consultant will monitor the modeling efforts of TxDOT's consultant and will assist the
City in addressing any negative results of those computer model runs.
Attachment 5.1 to the proposed contract amendment describes the recent activities
undertaken by the City's consultant in this ongoing process.
The City Staff continues to make every effort to expedite the MIS process and receive
environmental clearance for this project as soon as possible.
This $ 625 Million project falls principally within the City Limits of Grapevine and virtually
all of the impacts of this project including right of way taking, access and visibility affect
the citizens and businesses in Grapevine.

Authorization to proceed under this amendment will be issued by City Staff in
$ 25,000.00 increments as necessary.
Staff recommends approval.

RE: Traffic Engineering Services — Supplemental Agreement No. 5
Continuation of Schematic Resolution Support Work for the SH 114/121 Corridor
Dear Jerry:
As you are aware, we have been called on to continue to support the subject schematic
resolution. This effort will be beyond our previous scope. It is therefore requested that this
supplemental agreement for additional funding of $200,000 be approved to cover our foreseeable
effort. Recent efforts have included those described in Attachment 5.1.
Additional Scope of Services
Task 5 - Continue coordinating assistance to City, NCTCOG, and TxDOT as needed. TC&B is,
at the request of the City, currently participating in the schematic resolution effort. This effort is
a cooperative effort by the City of Grapevine, TxDOT, NCTCOG, HDR (TxDOT's MIS
consultant) and TC&B to reach a consensus on the final schematic for the corridor. It involves
refining alternatives, modifying geometrics, and coming up with specific improvements that are
acceptable to all entities. TC&B will, as a part of this effort, continue to provide geometric
solutions and analysis as needed to support the original intent of the alternative schematic
proposed by the City to provide appropriate access in the corridor.
Compensation and Liability
Task 5 - $200,000
Period of Service and Schedule
As directed.

Authorization to Proceed
All terms and conditions stated in the original agreement, dated May 24, 2001, will remain in
effect. This supplemental agreement covers only the additional work identified above. If this
request for a Supplemental Agreement meets with your approval, we will consider your
acceptance in the space provided below as our authorization to continue the additional effort.
Please return one signed copy of this supplemental agreement for our files.

ATTACHMENT 5.1
Recent SH 121/SH 114 Schematic Resolution Effort
Recent efforts completed under Supplemental Agreement No. 4 included the following:
• Provided analysis of TxDOT's sub -consultant's (HDR) alternatives, coordinated with TxDOT, HDR
and other entities per City of Grapevine's request.
• Attended meetings and provided exhibits; regularly updated City of Grapevine access exhibit based on
decisions made during the meetings.
Prepared numerous alternatives along SH 114 between FM 1709 and SH 26 which included:
a. Developed braided ramps between on-ramp from FM 1709 to southbound SH 114 and
off -ramp from southbound SH 114 to southbound Frontage Road.
b. Looked at access issues for the existing Sam's Club parking lot and provided
workable ramp alternative.
c. Provide slip ramp from Texas U -Turn to on-ramp from the SH 114 northbound
Frontage Road to northbound SH 114.
d. Provided direct connector from FM 1709 to southbound SH 121.
e. Provided ramp from FM 1709 to SH 114 southbound Frontage Road.
f. Provided reduced lane configuration along SH 114 northbound Frontage Road
between College and Wall Streets and developed more efficient traffic movements to
Wall Street and FM 1709.
g. Developed an alternative to pull the northbound managed lanes to the north to deny
FM 1709 traffic access.
Much of the work above required developing profiles for the alignments to see if they would work
geometrically.
• Provided numerous alternatives along westbound SH 121/114 between International Parkway and
William D. Tate which included:
a. Modified braided ramps, on-ramp from Loop 382 to SH 121/114 and off -ramp from
SH 121/114 to Main Street to increase weave distance on the mainlanes.
b. Modified on-ramp from International Parkway to SH 121/114 to increase weaving
distance on the mainlanes.
c. Developed bypass under Main Street with a connection to southbound SH 121. This
particular alternative required the development of numerous profiles.
Eliminated successive entrance ramps along northbound SH 121 at Sandy Lake; this work included
combining ramps from SH 26, IH 635 and the ramp from the northbound Frontage Road into one main
on-ramp to northbound SH 121. The work also included adding an off -ramp from northbound SH 121
to the northbound Frontage Road
• Reworked the above alternative, based on TxDOT comments, back to a successive on-ramp
arrangement but separated the IH 635 traffic from the SH 26 and northbound frontage Road traffic.
This required moving the off -ramp from northbound SH 121 to the northbound Frontage Road back to
the south.
• Modified the alignment of the direct connect from northbound SH 121 to northbound SH 114 to
eliminate the conflict with existing restaurants below.
• Modified bypass alignment from southbound SH 114 Frontage Road, under William D. Tate and
Main, which connects to the eastbound SH 121/114 Frontage Road to allow for an access ramp to
Main Street. This also required the elimination of the movement providing traffic from William D.
Tate to bypass Main Street.
The work within this period also included modifications which stemmed from meetings the City of
Grapevine had with other public entities. Some of this work included reworking the alignment of the
bypass from northbound SH 121 under Bass Pro to the northbound Frontage Road and eliminating the
connection from 111 635 to the bypass. Also, moving the ramp connection southbound SH 121
Frontage Rd to westbound SH 121/114, from the proposed configuration farther to the south and
thereby eliminating the complex braid geometry.
