DearJerry:
As requested, we have reviewed our proposal to identify the amount of our overall effort that will
address the City of Coppell's concerns in regard to interchange issues at Sandy Lake Road and
at BassPro Drive/Bethel Road. I estimate that the issues constitute between $9,000 and $10,000
of our project effort.

Re: SH114/121 Schematic Alternative Development
DearJer~:
In follow-up to our meeting with TxDOT and HDR on May 5, 2000, Parsons Transportation Group Inc. is
pleased to submit this proposal to provide professional traffic engineering and roadway design services in
connection with the City's efforts to optimize the SH114/SH121 MIS schematic in serving both regional
traffic and local access. We understand that the City is concerned about HDR's proposed schematic as it
currently exists. The existing access to the Mills Mall and to the Bass Pro area as well as the important
functions that SH 26 and Bus 114 (LP 382) will play in providing access to this important growth area of the
City are not adequately addressed in the current schematic. The purpose of this alternative design study
will be to develop and evaluate alternatives that will best provide for the existing and expected local access
requirements while providing for regional travel needs.
If accepted, this letter will become an agreement between the City of Grapevine (GV) and Parsons
Transportation Group Inc. (PTG) to provide the scope of services outlined below.

Parkway (FM 2499)/Grapevine Mills Parkway North/Sandy Lake Road area.
